Ten questions and ten answers about stem cells, and I will learn about her magic with you.

Through ten groups of questions and answers, this paper gives you the function and application of popular science stem cells, and shows you the important position of stem cell therapy in modern medical care.

Mother, the pilot of the boat of life, not only gave birth to us, but also promoted the reproduction of mankind. She is a great inheritor of life and a transmitter of love.

Cells, the weavers of the web of life, constitute the cornerstone of the human body, which is a miracle exhibitor with various forms and complicated functions.

The human body is a magnificent movement interwoven with countless cells, the harmonious resonance of 240 kinds and 60 trillion cells, and the subtle fusion of 4 major organizations, 36 organs and 8 major systems.

She is a special cell, but also the guardian of the source of life. She can regenerate new cells, replace aging cells and repair damaged tissues and organs. She is the mother of the cell world.

This kind of cell is the root of our life-stem cells.

With the progress of science, stem cell research has become one of the most advanced and active research directions in the global medical field.

However, for the general public, what exactly are stem cells? What does it do? What kind of people are suitable for repair intervention through stem cells? What are the risks even in treatment? This article will help you understand these questions easily through ten groups of questions and answers.

Ten questions and answers about stem cells

01

What are stem cells?

Stem cells are cells with self-renewal function and multi-directional differentiation ability.

Under certain conditions, these cells can differentiate into more than 220 different functional cells in human body. Because of its remarkable homing effect, stem cells can repair and replace damaged cells and promote organ regeneration. They are the basic cells that constitute various tissues and organs of the human body, so they are known as "the source of life" and are often called "universal cells" in the medical field.

02

What are the classifications of stem cells?

Scientific research shows that stem cells exist not only in embryos, but also in adults, which can be extracted from cord blood, umbilical cord, placenta, bone marrow, fat and other tissues.

Stem cells are divided into totipotent stem cells, pluripotent stem cells and unipotent stem cells according to their extensive differentiation ability.

Stem cells can be divided into embryonic stem cells and adult stem cells according to their stages of embryonic development.

According to the tissue type of stem cell differentiation, it can be divided into hematopoietic stem cells and mesenchymal stem cells.

03

What is stem cell therapy?

"Stem cell therapy" refers to a medical intervention that extracts stem cells from patients or uses other stem cells, cultivates them under laboratory conditions, and then transfuses them into patients through specific transplantation techniques, so as to repair the cells and tissues that have lost their functions, thus promoting their regeneration and improving their symptoms. At present, hematopoietic stem cells and mesenchymal stem cells are widely used in clinic.

04

What is the difference between autologous and allogeneic stem cells?

Autologous stem cells are derived from patients themselves, which have perfect tissue compatibility, no need for matching, high utilization rate of transplanted cells and no rejection.

Allogeneic stem cells are derived from individuals other than patients and have low immunogenicity. Autologous stem cells are not recommended for people with infectious diseases, major genetic diseases or other health problems.

05

How can stem cells be used to treat diseases?

Cells are the basic unit of life. Human life is accompanied by the process of self-replication and differentiation of stem cells from birth to growth. The ability of stem cells to treat diseases mainly stems from their biological characteristics, which include:

The ability of long-term survival and continuous self-replication;

It can differentiate across different lines and germ layers, showing high plasticity;

And its chemical tendency, that is, homing effect, provides an important biological basis for cell therapy.

06

Is stem cell therapy risky?

Compared with conventional drug therapy, stem cell therapy is considered safer and has fewer side effects. But this does not mean that the risk is zero. Looking at stem cell therapy objectively, the following are some main risks of stem cell therapy:

Tumor development: If stem cells divide or differentiate into abnormal cells uncontrollably, it may lead to cancer. This mainly applies to embryonic or fetal stem cells, or reprogrammed stem cells, because the risk is based on their pluripotency.

Immune rejection: The body may regard foreign stem cells as a threat and attack them, leading to inflammation and injury. This is more likely to happen in hematopoietic stem cells (HSC).

Infection or complications related to invasive medical procedures: Stem cell therapy may lead to infection or complications related to invasive medical procedures.

Drug interaction: Stem cell therapy may have unpredictable interactions with other drugs taken by patients, which may lead to adverse drug interactions.

Unconfirmed or untested stem cell therapy: There is also the risk that unscrupulous practitioners provide unconfirmed or untested stem cell therapy, which may be unsafe or effective.

The effect of treatment is uncertain: patients should also realize that stem cell therapy does not guarantee a cure, and in some cases, it may not be effective at all. Stem cell therapy may not provide lasting results, and patients may need additional treatment.

It should be noted that these risks may be different due to individual differences, treatment methods, stem cell types and other factors. Before receiving stem cell therapy, patients should fully discuss these risks with doctors and weigh the potential benefits and risks of treatment.

07

What diseases can stem cell therapy treat?

Stem cell therapy is mainly used in the fields of treatment, health care and beauty, and it is also used to improve some refractory diseases.

Heart disease: Stem cells can regenerate damaged heart cells and maintain the health and vitality of the heart through a specific process of induced differentiation in the treatment of heart disease.

Prevention and treatment of Alzheimer’s disease: Injecting induced differentiated stem cells can replace aging brain cells and improve cognitive function.

Treatment of liver cirrhosis: generate liver cells through differentiation, and promote the regeneration and repair of liver cells.

Cancer treatment: Directionally differentiated stem cells can enhance the body’s immune function and help fight tumors.

Treatment of premature ovarian failure: Stem cell therapy can restore ovarian function, promote the repair of damaged tissues, improve ovarian microenvironment, enhance reproductive capacity, prevent follicular atresia and promote follicular renewal.

Male hypofunction: Stem cell therapy can repair the aging of reproductive system, improve sexual function, maintain the balance of sex hormones, reduce nocturia, relieve the symptoms of prostatic hyperplasia, and help prevent prostate hypertrophy and other problems.

Enhance muscle function: with the increase of age, muscle function weakens, strength and relaxation function decline, and the body is bloated. Stem cell therapy can improve muscle function, enhance strength, improve body shape and show youthfulness.

08

What is the effect of stem cell therapy?

Stem cell therapy can be carried out by systemic infusion or fixed-point intervention. Clinicians adopt appropriate cell types and treatment strategies according to patients’ health status and disease needs.

Because this treatment can directly intervene in the cause of disease, avoid other physical injuries that may be caused by drugs and surgery, and help regulate the sub-health state, the effect is usually not limited to treating diseases, but also improving the overall function.

09

Is there an age limit for stem cell transfusion?

Traditionally, some types of stem cell transplantation, such as allogeneic bone marrow transplantation, often have age restrictions, and it is usually recommended to be 50 years old or under 45 years old. However, with the progress of medical technology, this limitation is being broken.

For example, it has been reported that a 71-year-old patient successfully received autologous hematopoietic stem cell transplantation, and a 69-year-old woman also successfully received her son’s hematopoietic stem cell transplantation.

These cases show that under proper medical conditions and monitoring, elderly patients may also successfully receive stem cell transfusion therapy, which proves that the age limit is gradually relaxing.

10

What are the taboo populations of stem cells?

Patients with advanced malignant brain tumors, especially brain tumors;

Patients with shock or general failure with abnormal vital signs (requiring disease correction) and those who do not cooperate with the examination;

Patients with heart, lung, liver, kidney and other important organ dysfunction (multiple organ dysfunction syndrome);

Patients with dysfunction of coagulation mechanism;

Patients with severe local infection;

Patients with positive serological results (such as HIV, hepatitis B, syphilis, etc.);

People with high allergic constitution or severe allergic history;

People with nervous system diseases or diseases that have not been diagnosed;

This group is in a special situation and has uncontrollable risks, so it needs careful diagnosis and treatment.

Write it at the end

Stem cells have excellent regeneration and repair functions, and these abilities will gradually weaken with age. Therefore, it is an increasingly popular choice to store healthy stem cells as early as possible, which will provide the possibility for future health management and disease treatment.

The 21st century will be the era of cell therapy, and the application of stem cells and immune cells is expected to play an important role in clinical treatment.

However, at present, except for the mature clinical application of hematopoietic stem cell transplantation, other types of stem cell therapy are mostly in the research stage, and strictly designed clinical trials are needed to prove their clinical advantages, safety and effectiveness, which need further study.

Moreover, non-compliant and eager stem cell therapy and research not only threaten the safety of patients, but also hinder the improvement of stem cell therapy and its research level, which needs the attention of legal supervision, and patients with hope in stem cell therapy should also be alert to fraud and pay attention to its development and related policies and regulations.

Some dating software is still "undefended" for minors.

  Multiple social apps can still be used normally without "real-name authentication". Insiders suggest that the youth mode should be turned on by default.

  Recently, many netizens found and reported that some dating software is not strict with the use of minors. The Beijing Youth Daily reporter found that when using multiple strangers’ dating software, there is no need for real-name authentication, and minors can use these strangers’ social software "unimpeded". It is particularly noteworthy that in terms of function, there is no difference between unauthenticated accounts and other accounts, and accounts without real-name authentication can also purchase adult products at will. In this regard, many people in the industry have suggested that the youth mode can be turned on by default when the user does not log in with an ID card.

  find

  Multiple social App users can also be rewarded without real-name authentication.

  The reporter of Beiqing Daily recently found that many social apps, such as soul, Detective, Momo, etc., can be used normally by simply choosing to log in with WeChat or mobile phone number without "real-name authentication".

  These platforms all suggest that users must be over 18 years old when registering. For example, after soul registers, users need to choose the date of birth, but users can enter the interface without hindrance by filling in a date over 18 years old at will. Among them, soul needs to use a virtual avatar, and exploration and Momo need to add a real and clear avatar.

  In the process of use, the above App will send a pop-up window in teenager mode to the user. The reporter of Beiqing Daily noticed that the youth mode entering Soul needs real-name authentication, and people’s faces will be dynamically recognized during the authentication process. After the tester enters his real name information, he can’t enter the teenager mode again. The teenage mode of exploring and momo is to set the password directly.

  In view of the fact that it can be used normally without real-name authentication, Momo customer service responded: "Some functions need real-name use." When asked which functions will be affected by not having a real name, the customer service did not give a positive answer. In addition, regarding whether the real name will restrict consumption, the customer service said: "No real name will not restrict consumption."

  When using the live reward function of Detective and Momo, even the account without real-name authentication will automatically jump to WeChat or Alipay.

  In terms of recharge, none of the above three softwares has relevant restrictions or secondary verification for minors. And there is no real name account and unlimited consumption, which can recharge the highest amount of soul coins, exploration coins, momo coins and VIP recharge.

  experience

  Push content is undifferentiated, making friends and shopping are not affected.

  The reporter of Beiqing Daily used an account without real-name authentication on a dating software, and marked "the second day" in the introduction. After searching for keywords such as "making friends in junior high school", "sexy underwear" and "adult products" on the home page, a lot of related push content appeared. The purchase of goods can automatically jump to WeChat or Alipay. In other words, if minors are not authenticated in this platform, it will not affect their use.

  After several keyword searches, Beiqing Daily reporter used the test account to open the above-mentioned dating software again, and the homepage push also became the corresponding content related to keywords, in which minor dating also appeared directly and many times. In the shopping column, most of the products pushed also meet the previous keywords.

  In the actual measurement, the reporter of Beiqing Daily also found that there are multiple video platforms in the youth protection mode, and the platforms will impose restrictions on young users in terms of content, usage duration and consumption.

  For example, the daily use time should not exceed 40 minutes, and it is forbidden to use the software from the evening to the next morning, and it is impossible to open or watch the live broadcast, reward, recharge, cash withdrawal and so on. For example, a survey shows that in the youth mode, except for the functions of mobile phone recharge and city service, other functions of life service, transportation and shopping consumption are all disabled, while the functions of financial management are directly hidden. Aauto Quicker and Tik Tok, short video applications, banned teenagers from watching live broadcasts, which fundamentally prevented the risk of teenagers’ recharge and reward. Tik Tok also closed Tik Tok Mall. Video platforms Iqiyi, Tencent, Youku and Mango TV have closed the membership center and all other consumption channels such as financial welfare and games. Bilibili has also closed consumer operations such as membership purchase and top-up rewards.

  suggestion

  Directly open the youth mode for the unauthenticated netizen platform.

  In response to the measured results of the reporter of Beiqing Daily, Professor Shang Jianhui, deputy dean of the School of Journalism and Communication of Hebei University, believes that the platform practice that has not yet imposed restrictions on young users does not conform to the norms. "According to the explicit requirements of the Regulations on the Protection of Minors’ Network (Draft for Comment) and the Regulations on the Protection of Children’s Personal Information Network, the network platform should formulate special rules and user agreements for the protection of children’s personal information. Therefore, this practice of the platform should be improved, otherwise it may cause harm such as premature maturity of children and deception of the network. "

  Professor Shang suggested how to improve the platform’s protection measures for minors. "At present, there are some voices in academic circles. The index system of minors’ network protection includes 19 indicators in six dimensions, including information prompt, technical protection, anti-addiction (comprehensive) management, emergency complaint and reporting mechanism, privacy and personal information protection system, scientific popularization and publicity and education."

  "Technical protection, information tips, scientific popularization and publicity and education are the weak links in the protection of minors on the Internet platform. The platform should first strengthen technical security protection and realize standardized management of the platform; Secondly, construct an omni-directional information prompt matrix to optimize the use environment of minors; Furthermore, practice the concept of multi-knowledge inclusiveness and do a good job in popular science and publicity and education; Finally, improve the youth model and enrich the content pool for minors. " Professor Shang said.

  Some operators who did not want to be named told the reporter of Beiqing Daily that "registering with a mobile phone number does not mean real-name authentication. Operators will not synchronize all users’ personal information to all platforms at will. It is not excluded that operators cooperate with some larger platforms to authorize the platforms to identify information through mobile phone numbers, but only if both parties sign an agreement to ensure the other party’s safe storage and standardized use of personal information. Therefore, it cannot be said that registering with a real-name mobile phone number is equivalent to real-name authentication. "

  Earlier, Jiang Yaodong, member of Chinese People’s Political Consultative Conference and former vice president of China University of Mining and Technology (Beijing), also suggested that "for users who have not been authenticated, the platform can default the user to enter the youth mode, which can protect minors from browsing age-appropriate content to the greatest extent."

  interlinkage

  According to public data, in 2021, the number of underage netizens in China reached 191 million, and the Internet penetration rate of minors reached 96.8%. According to a survey released by Beijing Internet Court, from June 2022 to May 2023, Beijing Internet Court accepted a total of 143 civil disputes involving minors, and the number of cases increased year by year, with game recharge and live rewards accounting for the largest proportion. Among them, the phenomenon that minors involved in litigation evade family supervision and anti-addiction measures is more prominent, and most minors evade family supervision and platform authentication measures. At the same time, minors are easily influenced by bad information. Some minors use the Internet to browse pornographic, bloody and violent bad content, and some minors are influenced by the online war and the "network water army" and learn to imitate bad online behavior.

Regenerative Medicine Breakthrough China Scientists Induce Human totipotent Stem Cells.

  Recently, researchers from China Academy of Sciences, Shenzhen Huada Institute of Life Sciences and other institutions have cultivated human pluripotent stem cells in a state similar to that of fertilized eggs developing for three days through somatic cell induction. This is the "youngest" human cell cultured in vitro in the world at present, and it is another subversive breakthrough in the field of regenerative medicine after scientists successfully induced human pluripotent stem cells. Related research results were published in the international academic journal Nature in the early morning of March 22nd, Beijing time.

  It is understood that researchers have developed a non-transgenic, fast and controllable "cocktail" cell reprogramming method, which can transform human pluripotent stem cells into totipotent 8-cell embryonic-like cells, that is, totipotent stem cells equivalent to the three-day development of fertilized eggs. This achievement will help to realize the in vitro regeneration of human organs in the future, and it is of great significance to solve the problems of organ shortage, allograft and xenotransplantation rejection.

  In 2012, the Nobel Prize in Physiology or Medicine was awarded to shinya yamanaka, a Japanese scientist who successfully induced mature somatic cells into pluripotent stem cells in blastocyst stage. The cells in human blastocyst stage are fertilized eggs developing 5-mdash; In the state of 6 days, its ability to further develop is limited.

  However, this study has made a big step forward in this field, and for the first time, embryonic cells with fertilized eggs divided for only 3 days were obtained. In the early stage of fertilized egg development, great changes have taken place every day, and it is these 2-mdash; In 3 days, scientists obtained human 8-cell embryonic-like totipotent stem cells through in vitro induction for the first time. This is the "youngest" human cell induced in vitro so far, and it has very strong development potential. This study will also help to unlock the key to the early development of human embryos.

  According to reports, these totipotent 8-cell embryonic-like cells reconstructed the embryonic state of fertilized eggs after only three times of division. Compared with pluripotent stem cells in the past, these cells can differentiate into placental tissues and may develop into more mature body tissues.

  "This progress is also a model of the combination of regenerative medicine and single cell sequencing technology." Dr. Liu Longqi from Shenzhen Huada Institute of Life Sciences, one of the authors of the paper, said, "The efficient identification and mechanism analysis of cells or tissues obtained by stem cell technology in vitro or in vivo will greatly accelerate the development of regenerative medicine."

  This is the first time that researchers have "transformed" human pluripotent stem cells into pluripotent embryonic cells in a real sense, so that people can reverse the "adult" version of cells into "infant" versions with more possibilities. At the same time, because the totipotent cells obtained this time are closer to the original state of early embryos, if they are used in regenerative medicine, the cultivated organs will be closer to the state of real organs, which is more conducive to transplantation.

  This breakthrough is due to the progress of single cell sequencing technology. In the past, researchers may have to process and culture thousands of cells, and the probability of success is less than 10%. Nowadays, based on the single-cell library sequencing platform (DNBelab C4) independently developed by Huada University, combined with the DNBSEQ sequencing technology created by Huada Zhizhi, scientists can conduct multidimensional single-cell analysis with high sensitivity and accuracy, quickly obtain cells with important development potential, and study the development direction of these cells.

  In this study, the research team also classified the induced pluripotent stem cells and injected them into mice for further development, and then used the single cell sequencing technology of Huada to conduct large-scale cell map analysis. Finally, the researchers confirmed that the experimental totipotent stem cells were highly similar to human 8-cell embryonic cells, which proved the totipotency of the cells. This provides a scientific basis for organ culture using patients’ own cells in the future and for organ transplantation and replacement.

  The research was led by China Academy of Sciences and Shenzhen Huada Institute of Life Sciences, with the participation of several research teams including Cambridge University, Jilin University and rajshahi University. This study has passed the ethical review and strictly followed the corresponding laws and regulations and ethical standards.

Pharmaceutical Business Advisor AstraZeneca Chloe Wang: Writing the Next Growth Decade with Ecosphere and Digitalization

    The column "Insight into New Trends and New Possibilities of Pharmacy" is a special program "Pharmacy Consultation" for the seventh anniversary of Ali Health Pharmacy jointly produced by Ali Health and Cyberblue. The purpose of this paper is to explore the new trend of medical and health industry in the new era from the perspective of pharmaceutical companies’ first site, and to discuss how pharmaceutical companies and Internet medical platforms can jointly build an ecology to provide users with more comprehensive, professional and convenient new ways of health services under the changing industry and around the changing needs of users.

    Today, we will review AstraZeneca’s innovative practice of deepening the China market for 30 years, and discuss the "entrepreneurial history" of this multinational pharmaceutical company in China from two dimensions of "digitalization" and "ecological circle".

    "Taking patients as the center and technology as the driving force, we will jointly explore the construction of a healthy and innovative ecology. While realizing digital medical care, we will help improve the integrated diagnosis and treatment and the whole course management plan, bringing new ideas for chronic disease management, primary care and multi-scene medical services. This is the fifth year of AstraZeneca’s health cooperation with Ali. In the year, AstraZeneca’s global executive vice president, international business and China President Chloe Wang sent a message to Ali Health.

    Behind this message, on the one hand, AstraZeneca’s positive layout in the digital field, and on the other hand, its interpretation in innovative ecological cooperation. These are the two main ideas that AstraZeneca cultivated in the China market for a long time.

    When talking about AstraZeneca, apart from its important role in tumor, cardiovascular and respiratory treatment, we will also mention AstraZeneca’s attitude of embracing the China market and focusing on the China market: in the past 30 years, AstraZeneca has embarked on its own path from product introduction to overweight manufacturing to the construction of innovative ecology.

    AstraZeneca embraced the China market vigorously, and the China market also gave AstraZeneca a good feedback-for a long time, AstraZeneca’s sales in China were among the best among multinational pharmaceutical companies.

    On the 30th birthday just past, AstraZeneca said that it would continue to "bring in" and "go out" simultaneously, push China’s innovation to the world and continue to embrace the China market.

    "Embrace the China market" is not just a slogan. How did AstraZeneca land? We try to deconstruct from two aspects: "digitalization" and "ecological circle".

    AstraZeneca’s Innovation Ecosphere

    As a leading pharmaceutical company in the world, AstraZeneca’s product innovation has always been at the forefront of the world. Although there are not a few multinational pharmaceutical companies with strong products entering the China market, AstraZeneca is the most outstanding in terms of volume and growth rate.

    Behind this is that AstraZeneca, on the basis of its rich treatment methods, has long been committed to promoting the mutually beneficial integration of global and local innovations in China: identifying the connection points between enterprises and policies and market trends, and the advantages of China’s supply chain, and constantly innovating the upstream and downstream cooperation models.

    In diagnosis, the industry trend of accurate detection should be followed. AstraZeneca and its partners announced the establishment of the MET HER2 Accurate Diagnosis Alliance to jointly build the capabilities in disease prevention and early screening, personalized treatment plan and so on.

    In terms of treatment, with the rise of local innovation in China, AstraZeneca actively explores ways to cooperate with local pharmaceutical companies with an open mind on its own product pipeline array. Last year, AstraZeneca and Unacon started cooperation on oxitinib. As a part of the long-term project of "lung cancer targeted joint scientific research cooperation", AstraZeneca is trying to link the clinical strength of local pharmaceutical companies to better improve the survival and benefit of lung cancer patients in China.

    In disease management, AstraZeneca starts from the scene of field diagnosis and treatment, helps medical institutions to build a bridge between doctors and patients, and provides solutions such as full course management and integrated diagnosis and treatment. AstraZeneca has signed strategic cooperation agreements with a number of medical groups to jointly integrate high-quality resources and strengthen the role of non-public medical care in China’s current medical system.

    From diagnosis to treatment to management, AstraZeneca’s strategic layout and cooperative ecology cover the complete treatment journey of patients.

    In addition to the traditional health industry chain, AstraZeneca is also actively embracing the new format of the health industry.

    In May this year, AstraZeneca and Ali Health jointly built a cardiovascular disease education and rehabilitation platform to provide customized and innovative digital health management services for patients with chronic diseases. Some consumption scenes of chronic diseases have been moved online, and through digital means, patients’ disease cognition and course management efficiency have been improved.

    "By building the" Troika "of innovative ecosystems such as China Smart Health Innovation Center (CCiC), International Life Science Innovation Park (iCampus) and AstraZeneca Zhongjin Medical Industry Fund (AZ-CICC Fund), AstraZeneca has joined hands with local pharmaceutical innovation forces in China to continuously and deeply build an international healthy innovation ecosystem." Zhu Lixuan, vice president of AstraZeneca China, head of the Digitalization and Business Innovation Department and the Business Strategy and Operational Excellence Department, explained the concept of the ecosphere.

    She said that AstraZeneca very much hopes to find an ecosystem partner who is also patient-centered and can complement each other’s business. The advantages of AstraZeneca in the field of medicine will be combined with excellent enterprises in the fields of equipment, special medical food, mental health and sports to achieve cooperation covering many aspects of the whole course management.

    Previously, foreign pharmaceutical companies relied on advanced products to meet the health needs of their stocks in the China market. Nowadays, the growth of the pharmaceutical industry needs everyone to make the cake in the market bigger together. The creation of AstraZeneca innovation ecosystem is the process of making the cake bigger with partners.

    Digitally open up the whole course management

    If the "ecological circle" is to improve the service experience of patients in the whole diagnosis and treatment process, then "digitalization" is a powerful tool to improve the medical and health service experience.

    The combination of "smart medical care" and "patient-centered" requires all parties in the medical system to cooperate through digital tools, provide continuous, convenient and high-quality services for patients, and track, record and guide each stage of the course.

    In this regard, AstraZeneca’s strategy is to focus on subdividing the treatment field, explore a set of landing models, and copy them to other fields.

    In terms of business, AstraZeneca supports associations, hospitals and experts to launch an innovative diagnosis and treatment system integrating screening, diagnosis, treatment and management; A digital management platform has been established in many fields, such as tumor, cardiovascular disease and chronic disease, so that every link of standardized treatment can be standardized, and standardized diagnosis and treatment data can be accumulated through standardized electronic medical records and quality control management in diagnosis and treatment.

    Faced with a series of problems such as uneven supply of medical resources in the low-end market and complicated process of patient diagnosis and treatment, AstraZeneca has applied for digital solutions such as remote consultation, multidisciplinary diagnosis and treatment (MDT) and distance academic training and education, and is committed to improving the quality of diagnosis and treatment in various places.

    In terms of channels, AstraZeneca also spared no effort to give full play to the advantages of digitalization.

    Grass-roots business has been difficult for many pharmaceutical companies to cover because of its wide distribution and low service efficiency. This is what AstraZeneca has been trying to overcome since it entered the China market. AstraZeneca has cooperated with many local e-commerce companies and Internet medical platforms, such as Ali Health, to create an online and offline integrated health service scene, which improves the accessibility of medical care and patient medication. In addition, AstraZeneca has specially built a grassroots business team to actively improve the medical service experience of patients in third-and fourth-tier cities.

    The innovation of digital diagnosis and treatment (service) and the improvement of infrastructure in distribution channels (tools) make AstraZeneca closer and closer to its goal in the grassroots market.

    In addition, based on the established standardized treatment database, AstraZeneca is also exploring the empowerment of product research and conducting comprehensive digital medical exploration and research.

    At the same time, AstraZeneca is also using some cutting-edge digital tools to empower the whole process.

    Shenrui Medical, a participating enterprise of AstraZeneca Zhongjin Medical Industry Fund, is one of the pioneers in the field of AI medical care in China. Its Dr.Wise AI medical auxiliary diagnosis system uses international cutting-edge technology to make artificial intelligence medical image diagnosis reach the advanced level, and it is in the forefront of the industry in the accurate diagnosis of diseases in various systems, which can provide clinical suggestions for doctors to make further diagnosis and treatment decisions. At present, the system is widely used in decision-making and follow-up of early screening of lung cancer, early screening of breast cancer and auxiliary assessment of stroke, which effectively helps to improve the efficiency of doctors’ diagnosis and treatment and reduce the rate of misdiagnosis and missed diagnosis.

    Digitalization is not a concept, but for "usefulness".

    "Realizing data insight and closed loop at each key node is the key to the success of digital transformation of pharmaceutical companies. But we can’t digitize for the sake of digitization. All digital transformations must be patient-centered, empower doctors and patients through digital innovation, improve the efficiency of disease management, and ultimately benefit patients. " Zhu Lixuan said this.

    Multinational pharmaceutical companies start businesses in China.

    Health is an eternal demand. No matter how the external environment changes, consumers are willing to invest in high-quality health needs.

    In the field of health consumption, there are both commodity consumption and service consumption, such as online consultation and telemedicine; It not only integrates cutting-edge scientific and technological innovations, but also integrates fine and intimate health guidance. Consumer demand is diversified, personalized and multi-level, and the update and upgrade speed is faster.

    Under the diversified consumer demand, AstraZeneca is exploring how to match the needs of China patients with more drugs and solutions.

    At first, AstraZeneca introduced abundant therapeutic tools to China. Since then, AstraZeneca has continued to expand the localization process in the supply chain to improve the accessibility of drugs at lower production costs.

    Nowadays, when the demand for health consumption is more and more diversified, from treatment to service, from effectiveness to accessibility, from the north to the low-end market, from simply eliminating illness to improving the whole process experience … AstraZeneca meets these diversified needs one by one. The process of finding the demand and satisfying it is a process of starting a business.

    Talking about AstraZeneca’s future layout of China market, Zhu Lizuan shared: "On the basis of the continuous improvement of agglomeration effect and mode maturity, the’ Troika’ of innovation centers, innovation parks and funds is expected to further strengthen their mutual coupling and driving operation modes and help more local innovation achievements to land. In the future, AstraZeneca will also promote more innovative models, innovative enterprises and innovative achievements in China to the world stage by building bridges to the sea, and vigorously promote the global layout and development of China enterprises. " Zhu Lixuan mentioned.

Many places in the country have successively adjusted the endurance category of the senior high school entrance examination to be exempted or selected.

  On March 10th, the Education Bureau of Hengyang City, Hunan Province issued a notice saying that after comprehensive research, it was decided to adjust the items and time of the physical education examination of Hengyang junior high school academic level examination in 2023: the middle and long-distance race (1000m for men and 800m for women) in the basic test items was adjusted from compulsory examination to exemption examination, and all candidates in this project were given full marks.

  This year, many places in the country have successively adjusted the plans for the senior high school entrance examination for physical education, and some places have adjusted endurance events such as long-distance running and swimming as optional items.

  Among them, on March 8, Hangzhou Education Bureau released the latest adjustment plan for the 2023 senior high school entrance examination physical examination. So far, 11 districts and cities in Zhejiang Province have officially announced the sports programs for this year’s senior high school entrance examination, and the 1000-meter running (boys) /800-meter running (girls) projects have been adjusted to "can run or not".

  The Paper noted that Lishui Education Bureau mentioned in answering questions from the public that candidates infected with novel coronavirus should carefully apply for physical endurance events such as 1000m (male) or 800m (female), and candidates who apply for such events should do a good job in personal health risk assessment.

  Lishui City Education Bureau also reminded that candidates who have been infected with novel coronavirus and other special physique should pay attention to the recovery training of physical skills and gradually increase the difficulty intensity when preparing for the exam. Warm-up exercises should be done before training, physical condition should be paid attention to during training, and rest should be paid attention to in time after training. If necessary, give feedback to the teacher or parents about your physical condition. If you have difficulty breathing, abnormal heart rate or excessive fatigue, you should consult a professional doctor in time.

  In Ji ‘an, Jiangxi Province, the notice issued by the Ji ‘an Municipal Education and Sports Bureau on March 6 stated that in 2023, there will be no compulsory items in the entrance examination for junior and middle school graduates, and the compulsory items (1000m for men/800m for women) will be adjusted to optional items. Candidates choose two items from five selected items for testing.

  The Education and Sports Bureau of Ji ‘an said that all localities should fully understand the background and significance of the adjustment of this year’s physical examination items in the province, that is, from three items of the original examination to two items of the examination, and from the original compulsory examination items to optional examination items, so as to take effective measures to prevent major risks.

  In addition, the "Notice on Doing a Good Job in the Physical Education Examination for Junior and Middle School Graduates in 2023" issued earlier by the Guangdong Provincial Department of Education also adjusted the compulsory items (men’s 1000 meters/women’s 800 meters and swimming) in the unified test project to optional items. The "Notice" pointed out that in view of the current epidemic situation in Guangdong Province and the physical health status of students, in order to effectively ensure the scientific, safe and smooth progress of the physical education examination for junior and middle school graduates in 2023, after in-depth analysis, comprehensive judgment and careful consideration, it was decided to make corresponding adjustments to the physical education entrance examination in Guangdong Province in 2023.

Keep enough cars and prepare enough people to go all out to ensure the express delivery "Spring Festival travel rush"

  CCTV News:Every year before the Spring Festival, it is the peak season for all kinds of express delivery. Since Spring Festival travel rush started on January 7th, the daily postal express delivery volume has been over 300 million pieces, with a peak of over 400 million pieces. What changes have been made to the express delivery capacity that will be tight in previous years? Can the express delivery business be guaranteed during the holidays? Is the way home by express delivery smooth?

  At 6: 30 in the morning, at this express outlet in Zhongguancun, the person in charge, Lei Liping, simply said a few words, and the express buddy immediately threw himself into the sorting work.

  As the nearest express terminal service point to customers, from 4: 00 in the morning, there are trucks coming into the field one after another, and express parcels sent from all over the country to nearby areas are pulled from the transit point. The express parcels waiting to be sorted and delivered quickly piled up a hill.

  "hurry up! Hurry up! " This is the word that reporters hear the most frequently at the scene. Lei Liping told reporters that near the Spring Festival, the peak of express delivery has been ushered in recent days. Because most of them are fresh food, gifts and other new year’s goods, in order to ensure the timeliness, the express delivered from all over the country in the morning should be delivered to customers before noon. Nearly 50 courier brothers in this outlet have to arrive at their posts before 6: 30 in the morning, and breakfast can only be solved.

  Less than 8 o’clock, the five express parcels sent in the morning have been sorted.

  Go all out to ensure the express delivery "Spring Festival travel rush", the grass-roots outlets at the end of delivery operate efficiently, and the circulation at the end is smooth. Then, what is the transition in express delivery with a wider business scope?

  The reporter saw in a courier transfer near the Capital Airport that dozens of unloading ports were full of trucks. On the other hand, there are long queues of vehicles waiting for unloading.

  Handling 600,000 peak packages per day is definitely not possible by manpower alone. The reporter saw at the scene that the automatic sorting equipment helped a lot. After unloading, these parcels were transported to the automatic sorting machine, and more than 600 sorting ports could be automatically divided into different parcel bags according to the area codes on the face sheet.

  Save enough cars and people. In order to cope with the peak of express delivery during the Spring Festival, recently, many express delivery companies have proposed "no fighting during the Spring Festival" to ensure the smooth flow of express logistics.

  In Beijing Xinfadi Fruit Wholesale Market, Wei Dongwen, who is in charge of contacting the truck service for merchants, asked about the shipment of merchants and contacted the truck by phone.

  Wei Dongwen told reporters that people have been going home for the New Year these days, but they have also left enough manpower to ensure the delivery needs of customers. During the Spring Festival, there are still many courier brothers who are ready to stick to their posts to ensure that the courier service during the festival is not interrupted.

  Shi Jianting and Zhang Huanrong, couples from Linfen, Shanxi, have stayed at the delivery line for four consecutive Spring Festival. The couple planned that after the 14th day of the first month, the list was running out, and they would go home at the wrong peak.

  The reporter learned in the interview that a number of measures have been introduced in various places to actively respond to the express delivery demand during the holiday season. Some express delivery companies start the "night delivery" mode, extend the delivery time at night, and give priority to timely delivery of drugs, epidemic prevention materials and food. Jiangsu issued 35 million yuan of government subsidies for the postal express delivery industry to stabilize and return to work, helping the postal express delivery industry to accelerate its recovery. In Luzhou, Sichuan, the bus driver undertakes the task of delivering the express delivery. After receiving the express delivery from the postal transport vehicle, the bus driver sorts and delivers the express delivery to the Jintong Post Express Station in each village to get through the "last mile" of the parcel entering the village.

Institute of Neuroscience, Chinese Academy of Sciences: There is the best research soil here.

  At the age of 30, Serina Liu became the head of a research team at the Institute of Neuroscience, China Academy of Sciences.

  It is the dream of young people doing scientific research to set up their own research groups. Serina Liu himself had never thought that this day would come so quickly.

  In 2018, the news that the world’s first somatic cloned monkey was born in the Institute of Neurology, Chinese Academy of Sciences was released, which was one of the most remarkable developments in the global scientific community that year. Behind this major breakthrough is a young team of "Dr. Tu", and Liu is really one of them.

  Serina Liu stood out from the crowd thanks to the innovative mechanism and system of Institute of Neurology, Chinese Academy of Sciences. After years of follow-up interviews with the Institute of Neurology of the Chinese Academy of Sciences, the reporter found that the best scientific research soil is accumulating here. After 20 years of exploring the reform of scientific research system, this young research institute is moving towards the ideal of becoming the world’s top scientific research institution. Aiming at the forefront of the world’s science and technology, a lean and efficient research team is marching forward bravely, striving to lead and promote the upgrading of strategic industries with major breakthroughs in basic scientific research, and make contributions to building an innovative country and building a world science and technology power.

  To grow up "lining", not talent "hat"

  In 2010, Serina Liu was admitted to the Institute of Neurology of Chinese Academy of Sciences from Shandong Normal University to study for a master’s degree, and joined the macaque platform hosted by her tutor Sun Qiang. In 2016, Dr. Serina Liu graduated and published a research paper on genetically modified monkeys with autism in the top international academic magazine Nature. With his academic achievements during his doctoral period, there is no problem in applying for top foreign laboratories. Serina Liu finally decided to stay and continue his postdoctoral research in the institute.

  Go to a good foreign laboratory as a postdoctoral researcher, and after publishing one or two good articles, apply to return to China to be a "thousand young people" — — This is the ideal growth track for most doctors in the field of life sciences after graduation. Moreover, with the "hat" of talents, the support of research funds, preferential policies for settling down and so on can follow. However, if you choose to go abroad, most of you can’t continue the project of "making cloned monkeys", and you can only do "short, flat and fast" projects in other directions.

  The purpose of Serina Liu’s stay is to continue to work on making monkey models of brain diseases. He knows that this is the breakthrough direction of the key layout of the Institute of Neurology of the Chinese Academy of Sciences, and he is eager to join in it. One of the main reasons why most brain diseases can’t be effectively treated is that the current mouse model for developing drugs is far from that of humans, and most of the drugs developed are ineffective or have side effects when tested in humans. The production of disease model monkeys will bring unprecedented bright prospects for the mechanism research, intervention, diagnosis and treatment of brain diseases.

  Muming Poo, an academician of the Chinese Academy of Sciences and director of the Institute of Neurology, also convinced Serina Liu that only by breaking through the somatic cell cloning technology of nonhuman primates can we truly solve a series of shortcomings faced by macaques as experimental animals, establish a competitive advantage in brain science research in China and become an international leader.

  "The domestic scientific research conditions are different, and the state pays more attention to personnel training. It is an inevitable trend to make more and more world-leading achievements in China." Serina Liu said, "In my opinion, no place can provide me with better opportunities and support than the nerve center."

  "For a young scientific research talent who gives up studying abroad and is willing to stay at home to challenge major scientific problems, if the challenge fails, can we correctly evaluate his ability and let him still have a good development prospect?" When Sun Qiang led the team led by Serina Liu to experience numerous failures and achieved the first major breakthrough in the world’s somatic cloning of monkeys, Muming Poo raised a question worth pondering.

  In July 2018, more than eight months after the birth of the cloned monkey, Serina Liu left the station early after only one year of postdoctoral work in the Institute of Neurology, Chinese Academy of Sciences, and was officially hired as a researcher and became a research team leader of the Institute of Neurology.

  In the past year, Serina Liu has obtained the same research start-up funds and operation funds as other researchers in the institute. His laboratory is 130 square meters, equipped with five employees, and recruits one or two students every year. "This is enough for a research group that has just started." Serina Liu said that he intends to complete the optimization and efficiency improvement of somatic cloning monkey technology in three to five years, and at the same time, open some interesting topics step by step, such as the neurobiological mechanism of puberty initiation in primates.

  Serina Liu’s growth trajectory is just one of the cases in which the nervous system does not take the usual path and innovates the system and mechanism.

  Speak by skill, not by title.

  "The research team leader recruited by the Institute of Neurology only looks at whether there is a good job, not whether there is experience in studying abroad." When Serina Liu hesitated to go abroad, Muming Poo’s words reassured him.

  This is not an exception, but a performance-centered talent use and evaluation system that the Institute of Neurology has been insisting on for many years.

  In 1998, the CPC Central Committee and the State Council made a major decision to build a national innovation system, and decided that the Chinese Academy of Sciences would launch a pilot project of knowledge innovation. As one of the important strategic arrangements of the pilot project, Chinese Academy of Sciences established the Institute of Neuroscience in November 1999, with Muming Poo as its director. At that time, the situation could be called "being ordered at a critical moment", and Muming Poo became the first foreign director of the Chinese Academy of Sciences.

  "Only by establishing a brand-new institute of modern scientific research system and using a new system and mechanism can we attract talents." At the beginning of its establishment, Muming Poo made up his mind to innovate the operation and management of scientific research institutes and vigorously reform the traditional scientific research evaluation and incentive system. His goal is to establish a top scientific research institution which is recognized by international peers and whose operation mode can be replicated and popularized in China.

  Since 2003, the Institute of Neurology has taken the lead in introducing an international scientific research evaluation system among national scientific research institutes. Here, heroes don’t ask the source, talents don’t have the distinction of "foreign soil", and researchers should speak by skill, not by title. Even well-known experts should abide by the strict assessment requirements of the institute, and even without a diploma, they can be hired as deputy senior professional and technical posts. All work is to create a good ecological environment for scientific and technological innovation.

  When receiving the olive branch from the nerve, Sun Qiang was still a little-known university lecturer. He graduated from Inner Mongolia University for Nationalities with no overseas study experience. At the age of 36, he had just been awarded the deputy senior title and experienced the failure of developing transgenic monkeys. He once considered whether to give up the research on nonhuman primates. At an academic conference, I learned about Sun Qiang’s practical foundation and technical level for many years. Muming Poo introduced him as a full-time senior engineer and entrusted him with the task of building a research platform for nonhuman primates.

  To work here, Sun Qiang only made one condition to Muming Poo: to bring two veterinarians with only junior college education. Although their education is not high, they are a very important part of the scientific research team and need spirituality and concentration to achieve the ultimate.

  At the beginning of 2018, the world’s first cloned monkey "Zhong Zhong" and "Hua Hua" cultivated by Sun Qiang’s team appeared in Cell magazine. This achievement, independently completed by scientists in China, is known as "a milestone breakthrough in the field of biotechnology in the world". The birth of the cloned monkey also proves that China has reached a stage from gradual and incremental innovation to a major breakthrough.

  Are "Dr. Tu" and "Dr. Tu" not as good as those who have drunk "foreign ink"? Obviously not. Major breakthroughs, such as synthetic insulin, have been made by local scientists in China, most of whom are young scientists. In Muming Poo’s eyes, young people are the most innovative when they are 25 to 35 years old, but many excellent students go abroad as postdoctoral fellows, and devote the time that they can do experiments wholeheartedly to foreign laboratories in order to become "foreign talents" and get the talent "hat" smoothly.

  "It seems that if you don’t go abroad, you can’t find a good job, and you don’t pay enough attention to the local talents you cultivate. This kind of employment orientation must be changed." Muming Poo regrets, "truly successful people don’t necessarily have to go abroad. It is very important to keep excellent doctoral and postdoctoral students in domestic first-class scientific research units and give them opportunities for innovation. There must be various mechanisms to encourage such talents. "

  This is what the nerve has been trying to do. Under the leadership of Muming Poo, the Institute of Neurology has continuously deepened the reform of mechanism and system, and made in-depth and extensive explorations and attempts in the innovation of system and mechanism such as postgraduate training, team research to promote cross-integration, selection and promotion, and evaluation.

  Yan Wang, secretary of the Party Committee of the Institute of Neurology, summed up the basic principles of talent work in the Institute of Neurology — — Provide a relatively stable scientific research environment, so that scientists can focus on research work; Carry out strict international assessment and implement a benign flow mechanism; Guide researchers to resist pressure and temptation, so that young scientists can work in a down-to-earth manner.

  With these three rules, the breakthrough is ahead, and all it takes is time. Of course, it is very important to delve into major issues.

  Stick to "big problems" instead of "short-term" topics.

  "Big problem" is a key word deeply rooted in the culture of the Institute of Neurology.

  It is precisely because of aiming at major scientific problems that the non-human primate research platform is built and perfected. In fact, since 2002, many research institutions in the world have started the research on somatic cell cloning of nonhuman primates. In 2010, Mitalipov, a scientist from Oregon Primate Research Center, led a team to successfully transplant cloned monkey embryos, but unfortunately, the success failed, and the embryos ended in abortion after 81 days of development.

  However, due to the high investment cost and long output cycle of primate research, at first, many researchers who took mice as experimental objects inside and outside the Institute of Neurology were not optimistic about the investment in somatic cloned monkeys. In 2009, Muming Poo made a public opinion, and used the director’s fund layout to build a non-human primate research platform. That year, the Chinese Academy of Sciences tried out the only stable support policy for the whole hospital system, including the director’s fund. Since 2012, the non-human primate research platform project has been supported by Chinese Academy of Sciences. The background is that the Chinese Academy of Sciences, as a national strategic scientific and technological force, launched the strategic pilot science and technology project (Class B) "Study on Brain Function Linkage Map" in this year. This special project is one of the first five Class B pilot projects initiated by the Chinese Academy of Sciences, which is earlier than the start time of related "brain projects" in the United States, Japan and the European Union.

  In 2014, the Chinese Academy of Sciences launched the "First Action" plan, which outlined the reform of the classification of research institutes and comprehensively promoted the reform of institutional mechanisms. In the same year, based on the Institute of Neurology, the Center for Excellence and Innovation in Brain Science of Chinese Academy of Sciences was established, becoming one of the first four centers for Excellence and innovation established by Chinese Academy of Sciences.

  In 2015, during the planning of "China Brain Project", scientists in China put forward a "one body and two wings" architecture, that is, the neural principle of brain cognition as the "main body" and the new means of diagnosis and treatment of brain diseases and the new brain-like intelligent technology as the "two wings". The Chinese Academy of Sciences responded quickly and planned the coordinated development of brain science and brain-like research. The Center for Excellence and Innovation in Brain Science and Intelligent Technology, jointly planned by Institute of Neurology and Institute of Automation, was formally established in this year.

  Major changes have spawned major outputs. Perhaps coincidentally, on November 27th, 2017, the 18th anniversary of the establishment of the Institute of Neurology, the somatic cloned monkey "Zhongzhong" was born. In Muming Poo’s view: "The reason for our success is that we saw that this problem can be solved and stuck to it, while most foreign laboratories gave up. Our success is due to the cohesion of a group of cutting-edge talents. "

  "If you want to make a breakthrough scientific discovery, you must do important problems. I hope that the teachers and students of the Institute of Neurology have the confidence to do the best work, have the confidence and courage to do important problems, and eventually make breakthrough scientific discoveries. " Muming Poo is convinced. The "baton" of evaluation is also guiding everyone to explore innovative major scientific issues in line with the direction of national strategic development, rather than simply doing the topic of "fast, safe and easy to publish articles".

  At the end of November every year, it is the "big gathering" of the Institute of Neurology. After the establishment of the Center for Excellence and Innovation in Brain Science and Intelligent Technology, this tradition continued and became the "big gathering" of the whole center, and the performance evaluation of the year was carried out at the same time as academic exchanges. The evaluation results are the basis for researchers to apply for annual research funds and adjust performance allowances, and directly affect their funding and promotion opportunities.

  The results of performance evaluation are divided into three grades: A, B and C. Members who have been rated as C for two consecutive years will be required to make rectification, and the annual performance allowance will be stopped during the rectification period; Members who have been rated as C for three consecutive years will be asked to withdraw; Members who have been rated as A for two consecutive years will be given priority in promotion assessment.

  Yan Wang remembers that when it was first implemented, the impact was great. Some researchers can’t figure out: why did they get a C in the evaluation because they have sent so many papers with high impact factors? Because the evaluation criteria are different, the "paper-only" evaluation system has been broken since the end of 2015, focusing on the contribution to the team’s key projects, excluding the results unrelated to the team’s projects; There are significant innovative achievements in the key areas of the center layout; The investment in interdisciplinary communication includes multi-unit "squatting" teaching and research, and guiding dual-tutor graduate students.

  What are good results and big results? What kind of achievement is a major breakthrough? "It is a major breakthrough to open up new scientific research fields and achieve milestones in the original scientific research fields. Looking around the world, the world’s top scientific research institutions have such achievements. Every scientific research field has well-known major unsolved problems, and it is the real leader in this field to continuously make major breakthroughs in one field. " Muming Poo said.

  It is necessary to "explore freely" and "tackle key problems by team"

  "It has been 5 years since I returned to China. Let’s see when I can get the first clinical approval." On July 8, Yang Hui, a researcher at the Institute of Neurology, wrote this sentence in a circle of friends, with a smiling expression of high morale.

  In 2014, 29-year-old Yang Hui became the youngest researcher in the Institute of Neurology, and served as the leader of the primate disease model research group and doctoral supervisor. "90% of rare diseases are incurable. Can we do something with gene editing?" Yang Hui said that rare diseases are actually not rare. There are more than 7,000 rare diseases found in the world, with more than 300 million patients, more than cancer patients. The goal of him and his team is to develop more efficient and safer gene editing tools and build a research and development platform for treating rare diseases. "The first gene drug in China will not be too far away".

  In the first half of this year, Yang Hui’s research group had a bumper harvest, and published two papers in Science and Nature. It was the first time in the world to confirm the off-target effect of single-base gene editing, and then further repaired the off-target "loophole" and established a new generation of single-base gene editing tools. The young researcher said frankly: "I’m still very uneasy, and I’m most worried about disappointing the students’ efforts day and night. Teacher Pu is still helping us to change articles over and over again during the Spring Festival holiday. Thank you for your efforts and hope that the results will benefit China patients as soon as possible. "

  The birth of somatic cloned monkeys undoubtedly brought Yang Hui closer to her dream. Starting from 2018, a monthly seminar on cloned monkeys will be held. In addition to the main personnel of the primate platform, many research groups of the Institute of Neurology will participate, expecting to bear more innovative fruits in deep cross-integration. Sun Qiang said that on the basis of successfully constructing the world’s first batch of somaclonal monkeys with dysrhythmia, more efforts are being organized, and the efforts of the Institute, the Center of Excellence and even the whole country are gathered to develop a variety of disease model monkeys and tool monkeys developed by somaclonal monkey technology as soon as possible. "Many research groups in the Institute have cooperated with us."

  In Muming Poo’s view, at present, breakthroughs in most fields require cooperative research, and establishing a concise and efficient research team is the key to a major breakthrough. "The biggest challenge in the biological science community at present is to establish an effective research team." The molecular mechanism and variety design of synthetic bovine insulin with full activity, high yield and high quality rice are not the results of individual combat. To make breakthrough work on major issues requires the team spirit of sincere cooperation, hard work and perseverance of each member, and puts the task and goal of team research above personal gains and losses.

  This is also the first-class scientific research culture that Muming Poo has always advocated, and the first-class scientific research institutions should have. "Looking for the development direction of the frontier of science must be free to explore. However, with the development of science and technology, it is difficult to make a real breakthrough only by individual’s free exploration. Therefore, it is an inevitable trend for young and middle-aged scientists to abandon the limitations of fame and fortune, cooperate with each other and jointly answer important scientific questions. "

  At the beginning of its establishment, the Institute of Neurology insisted on joint team research as the core way to solve major problems, and actively explored the establishment of scientific research systems and mechanisms that take into account collective goals and personal interests, demand orientation and free exploration. Here, most of the personal interests of scientific researchers are respected, most of their personal expertise is found, and valuable and distinctive frontier research fields are basically covered.

  Muming Poo has a profound understanding of the training methods of Chinese and Western scientists, and he hopes to promote the establishment of a new scientific culture in the nerve center and cultivate intellectuals who inherit China’s traditional values. In his view, Chinese researchers should have the spirit of selflessness, and more importantly, they should have the feeling of "worrying about the world first, and enjoying the world later" of China traditional intellectuals, so as to serve the country with scientific and technological achievements.

  "Please don’t buy things you don’t need in the near future. I am very seriously opposed to the idea of spending all the unspent funds before the end of the year. If we can’t use up the money, it means that we don’t need it. We must return it to the Chinese Academy of Sciences or other sources. This is the correct attitude of a scientist with social responsibility. " Muming Poo once sent an email to the research group leader in the institute.

  In his view, it is a basic social conscience that researchers should use research funds cautiously. The level of scientists is expressed by ideas and innovation, not by the latest models of instruments they have. The wind of "grabbing" resources once appeared in academic circles is a waste to society. The practice of the Institute of Neurology also proves this point. The rapid development depends not on the input of resources, but on the ideal of building a world-class scientific research institution and persisting in promoting the reform of the system and mechanism.

  At the beginning of his tenure as director of the Institute of Neurology, Muming Poo once put down his grandiloquence: "I have never been so confident in successfully establishing a world-class research institute on the land of China. This will be a research institute that will be recorded in the history of science in China. As the first director of the Institute of Neurology, I am determined to do my best to turn the Institute of Neurology into a fertile soil where the seeds of scientific invention will sprout, take root and blossom. "

  This year, 71-year-old Muming Poo will soon witness the 20th year of this research institute, which has devoted countless efforts to it, and complete another major turn. In the near future, it will continue to complete its mission and responsibility under the name of "Center for Excellence in Innovation of Brain Science and Intelligent Technology of Chinese Academy of Sciences".

  Innovation, innovation, and innovation.

  Fusion, fusion, re-fusion.

  This is the result of the times and the general trend. At present, the research of brain science and intelligent technology is facing unprecedented development opportunities. After 20 years of intensive cultivation, a research team led by outstanding scientists and with outstanding young scientists as the main body has become increasingly mature and has become a main force in the research of brain science and intelligent technology in China. After 20 years of reform and innovation, the rivers crossed, the bridges crossed and the roads traversed have been integrated into the great process of China’s scientific and technological innovation to overcome difficulties and become a cornerstone to consolidate the innovation-driven development strategy.

How to choose electric car charger?

With the popularity of electric vehicles, electric car charger has become an indispensable accessory for every electric vehicle user. However, there are many kinds of chargers in the market. How to choose a charger that suits you? The following will be popular science for everyone from several key aspects.

* * First, understand the battery type of electric vehicles * *

First of all, we need to know what kind of batteries our electric cars use, such as lead-acid batteries and lithium batteries. Different types of batteries have different requirements for chargers, so the choice of chargers must match the battery type.

* * Second, pay attention to the power and current of the charger * *

The power and current of the charger directly affect the charging speed and battery life. The higher the power, the faster the charging speed, but it may also cause damage to the battery. Therefore, when choosing a charger, we should choose a charger with moderate power and stable current according to the battery capacity and our own needs.

* * Third, pay attention to the safety performance of the charger * *

Safety performance is an important factor that cannot be ignored when choosing a charger. A high-quality charger should have multiple protection functions such as overcharge, overdischarge, overheating and short circuit to ensure the safety during charging. In addition, the charger with national certification mark should be selected to ensure product quality.

* * Fourth, consider the portability and ease of use of the charger * *

For users who often need to go out to charge, the portability and ease of use of the charger are also factors to be considered. Lightweight and compact chargers are easy to carry, while simple chargers can lower the use threshold.

* * 5. Understand the brand and reputation of the charger * *

Brand and word of mouth are important references when choosing a charger. Well-known brands usually have more advanced technology and stricter quality control, while good reputation means that products have been recognized by users in practical use.

To sum up, choosing a electric car charger that suits you needs to be considered from many aspects. I hope the above popular science content can help you to choose electric car charger better.

From 38 to 176, the descendants of Shenshan Village who fled the mountain came back!

   Jiangxi Daily reporter Zhang Tianqing Yang Jianzhi Li Xin

   Four years ago, the 24th day of the twelfth lunar month coincided with the lunar new year in the south. General Secretary of the Supreme Leader braved the snowstorm and came to Shenshan Village in Jinggangshan to pay a New Year call to the villagers. He said with deep affection: on the road to poverty alleviation, we can’t leave a poor family and a poor people behind.

   ▲ Jinggangshan Shenshan Village, villagers are communicating at the entrance of the village. Photography Jiangxi Daily reporter Hong Xiaobo

   After four years, another small year is coming. We drove along the winding Panshan Highway to Shenshan Village. There is a busy scene in the village, and everyone is nervously preparing for the annual village reunion dinner. The children danced happily, while the adults were busy, exchanging their harvests in the past year and their plans for the coming year. There was laughter everywhere.

   “1、2、3… … 176, there are 176 people eating New Year’s Eve this year. " Peng Zhanyang, a young village party secretary, counted the number of people one by one. "Well, there are 8 more people than last year!" He said.

   "Four years ago, among the 231 people in the village, the young descendants all went out, and only 38 old people and children guarded these 37 adobe houses. Who would have thought that in the past four years, the big guys have returned to the village one after another!" Lai Zhicheng, deputy secretary of the village branch, said happily.

   ▲ UAV aerial photography of Jinggangshan Shenshan Village Highway. Photography Jiangxi Daily reporter Hong Xiaobo

   Speaking of the past, Peng Shuisheng, a 79-year-old branch secretary, remembered the long-standing jingle in the village — — "There are women who don’t marry Shenshanlang, and Shenshan is a poor place; Sweet potatoes and sweet potatoes are the staple food, and young children flow abroad. " He said: "In those days, everyone who could go out left, and we called this ‘ Escape from the mountain ’ 。”

   Shenshan Village is located in the depths of Xiashan Mountain in Huang Yangjie, with only 5 fields per capita. No matter how well the fields are managed, they can barely make a living. The memory of poverty is rooted in the hearts of people in Shenshan Village from generation to generation. Escaping from the mountains has also become a common choice for the villagers.

   "Don’t go out can have what way? In the past, there was not even a decent road in the village. Although there were many bamboos on the mountain, the chopped bamboos had to be carried down by shoulders one by one. " Lai Fuqiao, 70, recalled: "In order to make some living money at home, every household in the village made bamboo chopsticks. After they were finished, they had to climb the mountain road for more than an hour to carry them out to sell. In the end, 100 pairs of chopsticks could only earn 2 yuan 30 cents, and many families earned less than 3,000 yuan a year."

   "In order to earn more money, the descendants in the village all went out to work, leaving us old guys to keep the mountain. At least, I was alone in this half of the mountain, and I didn’t even have anyone to talk to all day. I was very lonely. " Standing at the door of the house, 76-year-old Hu Yubao raised his arm and drew a half circle towards several houses on the hillside nearby.

   大山阻隔了神山村的发展,让神山村落下了“穷根”。2015年,神山村被评为省级贫困村,全村54户人家中,21户是建档立卡贫困户。

   越来越多精准扶贫的举措,加上越来越多回村创业的神山村人,让神山村“神气”了起来。

   村里的土地经过流转,460多亩种上了黄桃树、200多亩种上了茶树。21户贫困户都成了黄桃、茶叶合作社的“股东”,每年单是分红就有3000多元。

   5米多宽的盘山公路修通了,路灯也亮了,井冈山上的旅游大巴,顺着宽阔的新路开进村里来了。2019年,来神山村参观的游客达32万多人次。

   "Xiaohua, our farmhouse is understaffed, come back and help my parents!" Peng Shuisheng, the old township party secretary, called Peter Peng, the youngest son who works in a porcelain factory outside the mountain, back.

   Three brothers, Peng Changliang, Peng Qingliang and Peng Deliang, who have worked in Zhejiang, Guangdong and other places for more than 10 years, have started farmhouse music, keeping bees and selling honey, "Jinggang Hongshenshan Tea" and self-made "Shenliang Bamboo Wine", and their annual income has exceeded 400,000 yuan.

   Luo Linhui and Luo Lingen, two brothers, returned to the village from Longshi Town at the foot of the mountain, and opened a "tourist supermarket" at their doorstep, specializing in Shenshan local products, with an annual income of more than 200,000 yuan.

   The descendants who fled the mountain returned to the village, started their own businesses and became rich, showing their magical powers and attracting more people back to the village. The "census" of the resident population of village committees shows: 38 in 2016, 73 in 2017, 168 in 2018 and 176 in 2019 — — It has increased by 138 people in four years.

   "It’s good to come back. I’m not lonely anymore." Talking about changes, the old man Hu Yubao said: "The biggest change is that people talk anytime and anywhere." On the side, Peng Shuisheng gave a thumbs up: "I didn’t expect the afterlife in the village, and there are really many talented people!"

   The younger generation came back, and with the support of party committees and governments at all levels, the lives of people in Shenshan Village became richer.

   During the break, Peng Zhanyang sat with several villagers and made an "inventory" with his fingers broken: "One, two, three … … Since 2016, 22 villages have bought new houses in the city, 37 adobe houses have been reinforced and painted, the number of cars has increased from 7 to 39, and the number of farmhouses has increased from 0 to 21. "

   Li Shilong, an accountant of the village committee, added: "Four years ago, the per capita income in our village was only 3,000 yuan, but now it is 22,000 yuan. In the past, our village collective income was zero, and we didn’t have to do any accounts, but now it is 380,000 yuan."

   More changes are brewing!

   At the beginning of 2019, a company in Jinggangshan City took a fancy to Shenshan Village and invested more than 10 million yuan to build a rural revitalization research base in Shenshan Village. At present, the research base with a total area of more than 1000 square meters has been capped and can be put into trial operation after the Spring Festival. "After the research base is built, the research tourism, farmhouse music and homestay in Shenshan Village can be transformed into scale and standardization." Peng Zhanyang introduced.

   When we came down the mountain, we saw Tang Chao, the head of the tea cooperative, standing at the gate of the village Committee, giving dividends to 21 poor households’ "shareholders". 21 red gift bags filled with cash were placed on the table, and smiles bloomed on the villagers’ faces.

   Deep in the mountains, the chill still attacks people. But people’s hearts are already steaming!
