　　[Great motherland, unforgettable songs].

　　"Splendid rivers and mountains are picturesque, and the motherland is building a cross-horse. It’s a great honor for me to be an oil worker and travel around the world wearing an aluminum helmet … …” This heroic ode to oil workers is not only a clarion call to encourage oil workers from generation to generation to join in the construction of the motherland, but also an overall portrayal of the outstanding heroes of the working class in China. Although it was written more than half a century ago, it is still so exciting and exciting to sing today.

　　The composer Qin Yongcheng (1933— 2015) is the first generation composer trained in New China. During more than half a century’s creative career, he has created a large number of musical works with high artistic achievements and wide social influence, such as the song "I offer oil for the motherland", "Chairman Mao travels all over the motherland", My People，My Country, vocal concerto "Haiyan", symphonic poem "Two Little Cowboys" and movie music "Entrepreneurship" and "Marshal and Soldiers". He made great contributions to the music, art and education in our country all his life.

　　Three days with the "Iron Man"

　　In 1964, a notice brought Qin Yongcheng into close contact with Li Jiefu, a famous composer and president of Shenyang Conservatory of Music. It was this notice that made him have an indissoluble bond with oil workers all his life. In March this year, China Musicians Association organized some composers to experience life in Daqing Oilfield and created a batch of works reflecting oil workers. Dean Hijacking also received a notice, asking him to report to Sarthou, Heilongjiang Province on March 20th. After receiving the notice, the dean of the robbery immediately made preparations for leaving. Due to physical reasons, the college is going to find a young man to accompany the dean of the robbery to "go north". At the suggestion of the dean of the robbery, Qin Yongcheng will accompany him. Unfortunately, Qin Yongcheng was suffering from a high fever and had been in bed for three days. Upon hearing this, Dean Hijacking personally visited Qin Yongcheng’s home and told him to rest at ease for illness. In the face of this rare opportunity, Qin Yongcheng looked forward to his early recovery. Although his fever had gone down the next day, he was still very weak, and insisted on accompanying Dean Jiefu.

　　On the evening of 19th, Qin Yongcheng got his wish and boarded the train to the north. In the car, Qin Yongcheng finally put forward the question that was hidden in his heart: "Where are we going to Sarthou?" Dean Hijacking told him quietly: "Sarthou is a big oil field, called Daqing Oilfield, and it is still confidential." After moving to Daqing, Qin Yongcheng lived with many famous musicians such as Lv Ji, Qu Wei, Wang Xin, Zhang Lu and Jiefu in the guest house of Daqing Petroleum Command.

　　Since the next day, the oil field has arranged courses for musicians to introduce oil-related knowledge, from exploration and drilling to oil production and refining for ten days, with one content per day. Ten days later, the oilfield arranged for them to experience life in the first line. Qin Yongcheng, Jiefu and Wang Xin (songwriters of "Singing the Motherland") were assigned to the "1205 Hero Drilling Team" with Wang Jinxi, the "Iron Man", and lived together with the "Iron Man" for three days. During this period, Wang Jinxi told Qin Yongcheng that when he held a People’s Congress in Beijing in 1959, he saw that the buses in Beijing were in a heavy mood because of lack of oil and carrying gas bags. He also listened to him tell the story of the Daqing Petroleum Congress. In the spring of 1960, Wang Jinxi’s drilling team was in Yumen Oilfield. When it was heard that a large oil field had been discovered in the north, the whole country was going to hold a general meeting there, and immediately asked the superior to fight. They said goodbye to their relatives and boarded the train going north in their light clothes. Faced with the harsh climate, hard living and working environment, and poor equipment, oil workers shouted the loud slogan of "if you have the conditions, you should go if you don’t have the conditions" in order to get rid of the label of "poor oil" as soon as possible and break the economic blockade of western hostile forces. "When the oil workers roar, the earth will shake three times."Qin Yongcheng’s soul was strongly shocked and greatly impacted by his earth-shattering fearless revolutionary heroism. Especially in the days spent with Wang Jinxi and his heroic drilling crew, Qin Yongcheng’s understanding of oil workers has been greatly sublimated, and he has a strong emotional resonance. He is determined to create works that can reflect the spirit of oil workers to express his high respect for them.

　　A masterpiece completed in the canteen of the hostel.

　　After three days of experience, Qin Yongcheng returned to the guest house, and the Propaganda Department of the Party Committee of the Oilfield prepared a batch of lyrics reflecting the work and life of Daqing Oilfield and oil workers for them, hoping that composers would compose music for them. After the old composers had chosen the lyrics, Qin Yongcheng also chose them. At this time, a lyric jumped into his eyes, which was written by oil worker Xue Zhuguo, "I offer oil for my motherland." This first-person lyric is vivid and vivid, which vividly depicts the heroic and optimistic mood of oil workers and the fearless revolutionary spirit of fighting against the world. The more Qin Yongcheng watched it, the more he liked it. The more he watched it, the more excited he became. At this moment, he was inspired and full of thoughts. In the canteen of the hostel, he finished writing this work in just 20 minutes.

　　Inspired by the artistic conception of the lyrics, the prelude of the song adopts a fast speed, a lively and elastic rhythm, and a fluctuating melody line, like a train full of oil workers galloping in the splendid rivers and mountains of the motherland, from the northwest of the motherland to the northeast thousands of miles away. Then, the heroic song of the oil workers was introduced: "The beautiful rivers and mountains are picturesque, and the motherland is building a beautiful horse. I am honored to be an oil worker and wear an aluminum helmet to travel all over the world." The melody of the song is broad, fresh and smooth, which vividly depicts the bold spirit of oil workers and the revolutionary optimism full of pride and self-confidence. On the word "kua" of "kua steed", the melody absorbs the elements of rap music and adopts a sliding tone, which is not only in line with the rhyme of Chinese four tones but also forceful, and can better highlight the bold and hearty character of oil workers. These four sentences are lyrical paragraphs, which vividly depict the heroic fighting spirit and optimistic spirit of oil workers moving to the north and south and being at home all over the world.

　　In order to show the dauntless heroism spirit and heroic spirit of oil workers, who are "fearless of heaven, fearless of earth, and fearless of storm, thunder and lightning", Qin Yongcheng treated these two lyrics into short and powerful eight-point dotted notes and syncopated rhythm, which made the music more powerful and dynamic. At the same time, it not only forms a sharp contrast with the previous lyric paragraphs, but also lays a good foundation for the climax of the whole song that appears later.

　　The climax of the song is in the last two phrases, "I contribute oil to my motherland, where there is oil, my home is there". In order to make the climax of the song more prominent and infectious, Qin Yongcheng ingeniously treated the first beat at the beginning of this sentence as a rest, and started the word "I am" from the weak beat to highlight the word "ancestor" in the next section. Then, on the word "oil" for "offering oil", the melody adopts a circuitous upward movement, forming a large-span 10-degree interval in the range. In the last four bars of the song, Qin Yongcheng skillfully used the drawl of China’s traditional opera music for reference. It is worth mentioning that in the first draft of the work, the last four sections are not like this, but after Qin Yongcheng returned to school, he sang the work to friends and students, listened to and adopted everyone’s suggestions, and changed the original last simple melody into the current one-stop drawl. In this way, the music is more infectious and dynamic, which not only depicts the free and easy character of oil workers, but also makes the whole song end in an atmosphere full of optimism and pride. The revised work was published in the journal "Music Life" of Liaoning Branch of China Music Association, which soon became a hero’s ode to oil workers in the north and south of the motherland and inside and outside the Great Wall.

　　The only "composer of oil workers"

　　The first singer of this song, Liu Bingyi, a famous baritone singer of the former Central Orchestra, also played an important role in the promotion of this song. He and Qin Yongcheng also became attached to this song, and it was sung for 50 years. And Qin Yongcheng also started from this song, and successively created a number of excellent works reflecting oil workers. In 1973, as a key project of the Ministry of Culture, Changying filmed a feature film "Entrepreneurship" reflecting the Daqing Petroleum Congress, and specially invited Qin Yongcheng to create music for this film. Qin Yongcheng lived up to expectations, and created a number of well-known songs in his film music, such as Looking at Beijing with deep feelings, Entrepreneurial songs, and The Fragrance of Oil in Tianya Wan Li. Because of Qin Yongcheng’s outstanding contribution to the creation of oil-related music, the vast number of oil workers are familiar with the name Qin Yongcheng and affectionately call him "the composer of oil workers". In 1994, China Petroleum and Natural Gas Corporation (formerly the Ministry of Petroleum Industry) awarded Qin Yongcheng the honorary title of "composer of oil workers", and he was the only composer in China to win this honor. In 1996, China Records Corporation awarded Qin Yongcheng the "Golden Record Award" for this work, which was later included in the 20th century Chinese classics.

　　Praising the motherland and people and eulogizing the times and life are the themes of Qin Yongcheng’s life creation. It is precisely because of Qin Yongcheng’s deep patriotism, deep thoughts and feelings for the broad masses of the people, including oil workers, rich musical language based on Chinese excellent musical culture, and continuous absorption of rich nutrition and creative sources in the long-term in-depth social life that he created such immortal masterpieces represented by "I Contribute Oil to the Motherland", which are full of positive energy and the main theme of the times, and have high artistic value and appeal to both refined and popular tastes.

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.

　　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.

　　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.

　　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.

　　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.

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.

　　The Fourth Plenary Session of the 18th CPC Central Committee is a very important meeting held at the decisive stage of building a well-off society in an all-round way. The plenary session adopted "the Central Committee of the Communist Party of China’s Decision on Several Major Issues of Comprehensively Promoting the Rule of Law" (hereinafter referred to as the "Decision"), which made a top-level design and strategic deployment for comprehensively promoting the rule of law, clearly outlined the grand blueprint for the construction of China ruled by law, and specifically defined the road map and task book for comprehensively promoting the rule of law in various fields. It is a landmark programmatic document. The "Decision" makes an incisive exposition on safeguarding the authority of the Constitution, strengthening the implementation of the Constitution, and carrying forward the spirit of the Constitution, and puts forward clear requirements, which will surely raise the full implementation of the Constitution to a new level.

　　1. The Constitution is the fundamental law of the country, and it is the general charter for governing the country and safeguarding the country.

　　The "Decision" pointed out: "The Constitution is a concentrated expression of the will of the party and the people and a fundamental law formed through scientific and democratic procedures." We should fully understand the important position and role of the Constitution in the political and social life of the country, and earnestly enhance the consciousness and firmness of observing and safeguarding the Constitution.

　　The constitution is the concentrated expression of the common will of the party and the people. China’s Constitution is closely linked with the arduous struggle and brilliant achievements made by the Party and the people, the road ahead opened by the Party and the people and the valuable experience accumulated. As early as 1940, Comrade Mao Zedong pointed out that "after the success of the revolution had democratic facts, a fundamental law was promulgated to recognize it, which is the Constitution". Since the founding of New China, especially since the reform and opening up, the major principles and policies determined by the Party’s previous congresses have been fully reflected in the Constitution. For example, the 1982 Constitution and its four subsequent amendments timely wrote the Party’s major theoretical achievements such as Deng Xiaoping Theory, Theory of Three Represents’s Important Thought, Persistence in Reform and Opening-up, Primary Stage of Socialism, Socialist Market Economy, Ruling the Country by Law and Builders of Socialist Cause into the Constitution. The current constitution, in the form of the fundamental law of the country, establishes the development achievements of Socialism with Chinese characteristics’s road, theoretical system and system, reflects the common will and fundamental interests of the people of all ethnic groups in China, and is a high degree of unity of the party’s ideas and the people’s will. Safeguarding the legal authority of the Constitution means safeguarding the authority of the common will of the Party and the people, safeguarding the dignity of the constitutional law means safeguarding the dignity of the common will of the Party and the people, and ensuring the implementation of the constitutional law means ensuring the realization of the common will of the Party and the people. It is necessary to fully understand that only by earnestly respecting and effectively implementing the Constitution can the development of the cause of the party and the state and the happiness and well-being of the people be fundamentally guaranteed by law.

　　Constitution is a direct reflection of people’s democratic rights and wishes. The "Decision" pointed out that "the CPC Central Committee proposed constitutional amendments to the National People’s Congress and carried out constitutional amendments in accordance with the procedures stipulated in the Constitution." This fully embodies the organic unity of the party’s leadership, the people being the masters of the country and governing the country according to law, and highlights the distinctive characteristics of China’s socialist democracy. In the process of formulating and amending the constitution of our country, democracy is fully promoted, and procedures are strictly followed to ensure the extensive participation and high recognition of the whole party and society. When China’s first constitution was formulated in 1954, more than 8,000 representatives from state organs, Chinese People’s Political Consultative Conference, democratic parties, people’s organizations and all walks of life were organized to participate in the discussion, and more than 6,000 opinions were put forward after sorting out. In the subsequent national discussion, 150 million people participated, and more than 1 million amendments and suggestions were received from all over the country. In 1982, the draft amendment to the current constitution was fully discussed by the whole people for four months, and the opinions and suggestions from all sides inside and outside the party were widely solicited for the next four amendments. It can be said that the formation and development of the Constitution is a process in which the people directly exercise their democratic rights and reflect their democratic will, and it is also a process in which the wisdom and consensus of the whole party and the people of the whole country are highly condensed. It is necessary to fully understand that the constitution is formed and developed through scientific and democratic procedures, and it is the most extensive and true embodiment of socialist democracy in China.

　　The constitution is the highest code of conduct that the whole society must strictly abide by. Since the reform and opening up, China’s current constitution, with its supreme legal status and strong legal power, has guaranteed the people to be masters of their own affairs, promoted reform and opening up and socialist modernization, promoted the process of a socialist country ruled by law, and safeguarded national unity, national unity and social stability. Practice has proved that this is a good constitution that conforms to the national conditions, reality and the requirements of the development of the times. The Decision emphasizes that "all organizations and individuals must respect the legal authority of the Constitution" and that "people of all ethnic groups, all state organs and armed forces, all political parties, all social organizations, and all enterprises and institutions in China must take the Constitution as the fundamental criterion for their activities, and have the responsibility to safeguard the dignity of the Constitution and ensure its implementation", which further demonstrates the clear attitude and firm determination of the CPC Central Committee with the Supreme Leader Comrade as the general secretary in upholding the rule of law and governing the country according to the Constitution, and establishes the Constitution in the national governance system and institutions. We must always uphold the supremacy of the Constitution and fully understand that the Constitution, as the fundamental law to ensure the prosperity and long-term stability of the Party and the country, has the highest authority and must be fully respected and resolutely safeguarded.

　　Two, the life of the constitution lies in the implementation, and the authority of the constitution lies in the implementation.

　　The strength of the constitution is not only due to its lofty status, but also due to its effective implementation. Otherwise, the constitution can only stay at the level of "political declaration" and text. The "Decision" puts forward clear requirements for strengthening the implementation of the Constitution. We must persistently strengthen the implementation of the Constitution as the primary task and basic work of building a socialist country ruled by law, and pay close attention to it to ensure that the leading role of the Constitution in national governance and social governance is fully exerted.

　　Conscientiously fulfill the constitutional mission and work together for the prosperity of the country, the rejuvenation of the nation and the happiness of the people. The Constitution confirms the brilliant achievements made by our Party in leading the people’s long-term struggle, stipulates the nature and fundamental system of state power under the people’s democratic dictatorship, and defines the fundamental task and general goal of the country’s future construction and development. It is the highest embodiment of the central work, basic principles, major principles and important policies of the Party and the country in the new period. We should bravely shoulder the historical heavy responsibility and sacred mission entrusted by the Constitution, persist in emancipating our minds, comprehensively deepen reform, make overall plans to promote the construction of socialist economic, political, cultural, social and ecological civilization, and strive to achieve the goal of "two hundred years" and the great rejuvenation of the Chinese dream by the Chinese nation. We must adhere to the constitutional concept that all state power belongs to the people, adapt to the new requirements of promoting economic and social development and expanding people’s democracy, and mobilize and organize the people to manage state and social affairs, economic and cultural undertakings through various channels and forms in accordance with the provisions of the Constitution and laws, so as to jointly build, enjoy and develop together, so as to maximize the realization and maintenance of the people’s yearning for a better life.

　　Always abide by the constitutional principles and adhere to equality before the law. Equality is the basic attribute of socialist law. China’s Constitution stipulates: "All citizens of People’s Republic of China (PRC) are equal before the law." All citizens in China are equal in the application of laws, regardless of nationality, sex, occupation, family background, religious belief, education level and property status. The "Decision" once again reaffirms this important principle, emphasizing that any organization or individual "must operate within the scope of the constitutional law, must exercise power or rights, perform duties or obligations in accordance with the constitutional law, and must not have privileges beyond the constitutional law". It is necessary to safeguard the unity, dignity and authority of the national legal system and effectively ensure the effective implementation of constitutional laws. No one will be allowed to substitute words for laws, suppress laws and bending the law with power under any pretext or in any form. It is necessary to focus on standardizing and restraining public power, strengthen supervision, make sure that the right must be held accountable, the right to use it is supervised, and those who violate the law must be investigated, and resolutely correct those who fail to abide by the law, enforce the law lax, and fail to investigate the law.

　　Vigorously carry forward the spirit of the constitution, and effectively embody and run through the whole process of governing the country according to law. The core of the spirit of the Constitution is that the people are the masters of the country. The "Decision" emphasizes that it is necessary to "improve the socialist legal system with Chinese characteristics with the Constitution as the core" and "make every legislation conform to the spirit of the Constitution, reflect the will of the people and win the support of the people". This is an important premise and foundation for the correct and unified implementation of the Constitution. By the end of 2013, there were 243 effective laws, 731 administrative regulations and 9347 local regulations (including autonomous regulations and separate regulations) in China. It is important to keep these laws and regulations consistent with the spirit of the Constitution. The basic principles and systems established by the Constitution, the basic spirit of regulating state power and realizing citizens’ rights, etc., need to be refined through laws, regulations and other normative documents, and more importantly, the state administrative organs, judicial organs, procuratorial organs, all social organizations and all citizens need to consciously abide by them to implement them. It is necessary to regard the Constitution as the highest legal norm, strictly follow the clear statutory authority and requirements of the Constitution, scientifically legislate, strictly enforce the law, justly administer justice, and abide by the law by the whole people, so that the spirit of the Constitution can be fully reflected in all aspects of the rule of law.

　　Effectively safeguard the authority of the Constitution and resolutely investigate and correct all acts that violate the Constitution. It is the basic requirement of governing the country according to law and an important embodiment of the implementation of the constitution to abide by the law and prosecute those who violate the law. The current constitution meets the needs of building a well-off society in an all-round way and realizing the Chinese nation’s great rejuvenation of the Chinese dream, and its core position in the socialist legal system with Chinese characteristics has been formed. However, in real life, some departments just regard the Constitution as a supreme law. Many people think that the Constitution has little to do with ordinary people, and violations of the Constitution occur from time to time. In view of these problems in the implementation of the Constitution, the Decision emphasizes that "all acts that violate the Constitution must be investigated and corrected". It is necessary to formulate and improve the system of investigating the violation of the constitution, make clear provisions on the constitutive requirements, responsibilities, measures and procedures of investigating the violation of the constitution and strictly implement them, so that violations of the constitution can be stopped and corrected in time and the supreme authority of the constitution can be respected and safeguarded.

　　Adhere to the party’s leadership and unify the party’s leading the people in formulating and implementing constitutional laws with the party’s adherence to activities within the scope of constitutional laws. This is a profound summary of our party’s experience in governing the country, a deepening understanding of our party’s ruling laws, a fundamental embodiment of constitutional principles with people’s sovereignty, basic human rights, power restriction and socialist rule of law as the main contents, and the key to the implementation of the constitution. Our party leads the people to formulate the constitution, and leads the people to abide by and implement it. To govern the country according to law, we must first govern the country according to the constitution; The key to governing according to law is to govern according to the constitution. To strengthen the implementation of the Constitution, we must always adhere to the leading core role of the Party in taking the overall situation into account and coordinating all parties, adhere to the organic connection between the internal laws and regulations of the Party and constitutional laws, be good at making the Party’s ideas become the will of the state through legal procedures, be good at making the candidates recommended by the Party organizations become the leaders of state organs through legal procedures, be good at implementing the Party’s leadership over the country and society through state organs, and be good at using the principle of democratic centralism to safeguard the central authority and the unity of the whole party and the whole country.

　　Three, improve the supervision mechanism and procedures for the implementation of the Constitution, and effectively enhance the effectiveness of constitutional supervision.

　　Constitutional supervision is an important institutional form to ensure the implementation of the constitution and safeguard its authority and dignity. The implementation of the constitution cannot be separated from the constitutional supervision. Since the promulgation and implementation of the 1954 Constitution, especially the 1982 Constitution, China has continuously explored and gradually established a constitutional supervision system with China characteristics. Promoting the rule of law in an all-round way and strengthening the implementation of the constitution have put forward new and higher requirements for constitutional supervision.

　　Improve the constitutional supervision system of the National People’s Congress and its Standing Committee. China’s Constitution stipulates that the National People’s Congress and its Standing Committee are responsible for supervising the implementation of the Constitution. This reflects the system design that the National People’s Congress is the highest organ of state power and exercises state power on behalf of the people. Practice has proved that it conforms to China’s national conditions. The "Decision" emphasizes "improving the constitutional supervision system of the NPC and its Standing Committee", which not only highlights that the NPC and its Standing Committee have the highest constitutional supervision power, but also points out the direction of efforts to promote the institutionalization of constitutional supervision. It is necessary to improve the supervision mechanism and procedures, further clarify the object, scope and methods of constitutional supervision by the National People’s Congress and its Standing Committee, and make the principle requirements specific and procedural, so as to make the constitutional supervision more standardized and effective.

　　Give full play to the role of constitutional interpretation. According to the spirit of the Constitution, it is very important to explain the contents, meanings and boundaries of the Constitution, so as to ensure and supervise the full implementation of the Constitution. In the face of the complicated international situation and arduous domestic tasks, especially in the decisive stage of building a well-off society in an all-round way, it is necessary to pay attention to the use of constitutional interpretation and strengthen the function and effectiveness of constitutional supervision to solve the new situations and problems faced by reform and development according to law and safeguard national unity, national unity and social stability. In order to promote the concretization and institutionalization of constitutional interpretation, the "Decision" emphasizes "improving the procedural mechanism of constitutional interpretation". It is necessary to establish and improve the system of constitutional interpretation, clarify the conditions for submitting constitutional interpretation, the initiation and acceptance of requests for constitutional interpretation, the deliberation, adoption and publication of constitutional interpretation cases, ensure the implementation of constitutional interpretation, complement the advantages of constitutional amendment, and advance with legal interpretation, so that our constitution can keep pace with the times and keep pace with the times on the basis of maintaining stability and authority.

　　Strengthen the record review system and capacity building. It is an important content and link of constitutional supervision to record and review laws, administrative regulations and local regulations. According to statistics, by the end of 2013, the National People’s Congress Standing Committee (NPCSC) had received a total of 502 administrative regulations, 22,253 local regulations (including autonomous regulations and separate regulations) and 189 judicial interpretations. For the problems found in the review that are inconsistent with the constitutional laws, the enacting organs have been urged to amend or abolish them. The "Decision" emphasizes strengthening the record review system and capacity building, including all normative documents in the scope of record review, revoking and correcting unconstitutional and illegal normative documents according to law, and prohibiting local governments from issuing documents with legislative nature. It is necessary to improve the filing and review mechanism, improve the execution and binding force of the system, strengthen the cooperation between legislative supervision institutions, establish and improve the coordination and communication mechanism, effectively improve the filing and review ability, enhance the actual efficiency of filing and review, and safeguard the unity of the Constitution and the law.

　　Guide all sectors of society to actively participate in constitutional supervision. All power in our country belongs to the people, and every citizen has the responsibility of consciously respecting and maintaining the constitution itself, as well as the right and obligation to participate in supervision. According to statistics, since 2004, there have been 1,137 censorship suggestions put forward by citizens and organizations, of which 475 are within the scope of filing and censorship in the National People’s Congress Standing Committee (NPCSC). It is necessary to give full play to the important role of socialist deliberative democracy in constitutional supervision, pay attention to the democratic supervision role of the CPPCC and the United front, organize and guide democratic parties, people’s organizations and people from all walks of life to conduct in-depth investigations and studies on major issues related to the implementation, revision and interpretation of the Constitution, and actively make suggestions and suggestions. It is necessary to expand the channels for citizens to participate in constitutional supervision in an orderly manner, explore the establishment of an opinion processing and feedback mechanism, and fully mobilize the enthusiasm of all sectors of society to participate in constitutional supervision, so as to have a broader consensus and a solid foundation.

　　Fourth, the foundation of the constitution lies in inner support, and the power of the constitution comes from sincere belief.

　　Only when the constitution is deeply rooted in the hearts of the people and enters the masses of the people can it truly become the conscious action of all the people. It is necessary to enhance the conscious awareness of the whole society to be loyal to, abide by, safeguard and apply the Constitution, establish the belief and awe in the Constitution, and provide spiritual motivation and ideological guarantee for comprehensively promoting the rule of law and building a socialist country ruled by law.

　　Constitutional education is widely carried out in the whole society. The constitution is "a piece of paper with people’s rights written on it", which should be mastered, observed and used by the people. The "Decision" clearly designated December 4th, when the current Constitution of China was promulgated and put into effect, as the "National Constitution Day" every year, which provided an important opportunity for the centralized publicity and popularization of the Constitution. It is necessary to further improve the legal education system, highlight and strengthen constitutional education, make full use of various media to popularize constitutional knowledge, explain the spirit of the constitution, spread constitutional ideas, form a strong atmosphere for studying the constitution, and make the constitution a household name. It is necessary to bring constitutional education into the whole process of national education, starting with dolls and cultivating constitutional awareness from an early age. Through constitutional education, all the people should realize that the constitution is not only the highest code of conduct that must be observed, but also the most powerful weapon to protect their rights, fully believe in the constitution, actively use it, and become loyal advocates, conscious followers and firm defenders of the constitution.

　　Party member cadres should take the lead in safeguarding the dignity of the Constitution. Party member cadres and state functionaries have an important leading and exemplary role in observing and maintaining the Constitution. The "Decision" requires that party organizations of people’s congresses, governments, CPPCC, judicial organs and procuratorial organs at all levels should lead and supervise their units to abide by the constitutional laws. It is necessary to establish and improve the system for party and government leading cadres at all levels to study the Constitution, regard the Constitution as the study content of the theoretical study center group of the Party committee (party group), as an important aspect of cadre education in party member, and list it as a compulsory course for Party schools and administrative colleges, so as to comprehensively strengthen the study and mastery of the contents and basic spirit of the Constitution. It is necessary to educate party member cadres, especially leading cadres, to take the lead in establishing constitutional consciousness, cultivate constitutional thinking, and take the constitution as the criterion for judging right and wrong; Take the lead in acting in strict accordance with the Constitution and enhance the ability to observe, analyze and solve practical problems according to the Constitution; Take the lead in promoting constitutional practice, conscientiously perform the duties entrusted by the Constitution, and fight against all acts that undermine the authority and trample on the dignity of the Constitution, so that the Constitution truly becomes the highest rule of state governance and the fundamental principle that must be followed in carrying out its work.

　　Establish a constitutional oath system. The "Decision" clearly stated that "a constitutional oath system shall be established, and all state functionaries elected or appointed by the National People’s Congress and its Standing Committee shall publicly take an oath to the Constitution when they officially take office". The oath ceremony of the constitution strengthens the spirit of the constitution through solemn forms, which helps to enhance the sense of awe of the constitution and remember the solemn commitment made to the constitution; It is helpful to improve constitutional consciousness and cultivate constitutional belief. This innovative measure is of great significance for carrying forward the spirit of the Constitution and showing its authority. At present, among the 142 countries with written constitutions in the world, 97 countries have stipulated the oath system, and China is constantly exploring and practicing it. In March 2013, General Secretary of the Supreme Leader said at a meeting of the 12th National People’s Congress: "We will faithfully perform our duties entrusted by the Constitution, be loyal to the motherland, be loyal to the people, fulfill our duties, stay up all night in public, serve the people and do our best for the country." In December of the same year, 501 judges in the Supreme People’s Court solemnly swore allegiance to the Constitution and laws facing the national flag in accordance with the Provisions on Judge People’s Republic of China (PRC)’s Oath (Trial). We should conscientiously implement the constitutional oath system, clarify the specific procedures, contents, supervision and legal responsibilities of the oath, and make it a new important institutional form to ensure the implementation of the constitution and safeguard its authority and dignity.

　　People’s Daily (November 11th, 2014, 06 edition)

Guangzhou has built a high-speed highway, ranking first in the province. The "three-ring+nineteen-shot" main skeleton road network basically formed the northern section of the second airport expressway. On December 30, the northern section of the second airport expressway invested and constructed by Guangzhou Jiaotou Group passed the handover acceptance and was open to traffic. After this section is opened to traffic, a second high-speed passage will be added directly to Baiyun Airport, so that citizens in the north and east of Guangzhou will not need to detour by plane. The North Section of the Second Airport Expressway connects the North Second Ring Expressway, Huaguan Expressway and other national highways such as G106 and S118, forming a closed-loop regional traffic pattern of Guangzhou Airport and a new northbound exit passage, which will further enhance the distribution capacity of Baiyun Airport and accelerate the development of the airport economic zone, and play an important role in improving the layout of Guangzhou expressway network, alleviating the "bottleneck" of northbound exit traffic in Guangzhou, constructing the Pan-Pearl River Delta expressway pattern centered on Guangzhou, and promoting the interconnection of Guangdong-Hong Kong-Macao Greater Bay Area. Up to now, Guangzhou has built a high-speed highway with a mileage of over 1,100 kilometers, ranking first in the province in terms of construction scale, and the "three-ring+nineteen-shot" main skeleton road network has basically taken shape. Avoid congestion and bypass to build a second high-speed passage through the airport. "Driving to Baiyun Airport, the airport expressway is the only way." Mr. Li told reporters. However, on holidays, the traffic volume increases, and the airport expressway is often congested. "Leave some time in advance for holidays in case the traffic jam can’t catch up with the plane." With the opening of the northern section of the airport’s second expressway, Mr. Li’s worries will be effectively alleviated.The second expressway of the airport starts from Shanqian Interchange on the north extension line of the airport expressway and ends at Huangcun Interchange on Guangzhou-Shenzhen Expressway, with a total length of 44.46 kilometers. The project is roughly bounded by the North Second Ring Expressway and is divided into the northern section and the southern section. The northern section of the project is 22.11 kilometers (including 1.36 kilometers of connecting lines), with the construction standard of 8 lanes in two directions and the design speed of 100 kilometers per hour, with 7 interchanges and 1 management center. After the opening of the North Section of the Second Airport Expressway, the high-speed network around Baiyun Airport forms a closed loop, and citizens have one more route to choose from to go to the T1 and T2 terminals of Baiyun Airport or the surrounding area. They can drive from the North Section of the Second Airport Expressway to Fanghua Road and then to the T1 terminal via T3 interchange. In the future, after the planned road at the airport is completed and opened to traffic, the accessibility of the road network will be further improved. Citizens can switch from the airport north interchange to the T2 terminal and from the T3 interchange to the T3 (planned) terminal, which will effectively alleviate the traffic congestion of citizens during holidays, and citizens in Huadu District and Baiyun District can also reduce road detours when going to the airport. It is reported that the south section of the second expressway of the airport has started construction in an all-round way. When it is completed and opened to traffic, it will connect the northern section of the project and China Unicom’s seven expressways, and become an important highway hub in Guangdong-Hong Kong-Macao Greater Bay Area, further improving the "three-ring+nineteen-shot" expressway network, focusing on upgrading the energy level of the external expressway corridors in the directions of Guanghui, Guang ‘ao, Guangzhao and Guangqing, helping to build a Pan-Pearl River Delta expressway network with Guangzhou as the center and create a "one-hour traffic circle" in Guangdong-Hong Kong-Macao Greater Bay Area."After the second expressway of the airport is opened to traffic, the driving time from Tianhe to Baiyun Airport will be shortened from 1 hour to 30 minutes, and it will also become the fastest way for major cities in Guangdong-Hong Kong-Macao Greater Bay Area such as Dongguan, Foshan and Zhaoqing to go to Baiyun Airport." The person in charge of the second expressway project at the airport said. Insist on green and intensive construction to build Guangzhou Expressway demonstration project. The northern section of the second expressway of the airport passes through urban dense areas, crossing (passing through) high expressways, national and provincial highways and rapidly transforming roads, railways and subways for many times. The buildings (structures) and pipelines along the line are complicated and the construction requirements are extremely high. In this regard, Guangzhou Jiaotou Group has always adhered to the new development concept, focusing on intensive land conservation, safe construction and green construction. In the overall scheme selection, the route should be optimized on the principle of occupying cultivated land, fertile land and economic forest as little as possible; In the design stage, bridge structure should be adopted as much as possible to reduce the land occupation; Minimize temporary land occupation during the construction stage; After completion, vegetation, cultivated land and municipal roads will be restored in time. In addition, rainwater collection and accident emergency pools are set up on the road section passing through the water source protection area, and rainwater and sewage on the road surface are collected and treated centrally; Sound insulation and noise reduction measures are adopted in the road sections passing through environmentally sensitive points such as villages, campuses and residential areas, such as SMA, OGFC and PAC combined noise reduction pavement and fully enclosed sound insulation screen, so as to minimize the impact on the surrounding environment. It is understood that there are two underpass tunnels in the northern section of the second expressway of the airport.They are the airport north tunnel, the longest two-way eight-lane expressway in China with a length of 3,012m, and the airport south tunnel, the widest expressway in China with a length of 1,100m. By adopting the scheme of underpass tunnel, the environmental friendliness is improved and the construction difficulty is also increased. "Airport North Tunnel is located next to Liuxi River, with complex geological environment and great risk of collapse." The person in charge of the project said. In order to overcome the construction difficulties, geological conditions are taken as an important consideration in the scheme design of the north section of the second expressway of the airport, and the scheme is dynamically adjusted during the construction, and measures such as real-time monitoring and strengthening protection are taken to ensure the construction safety. At the same time, the northern section of the second expressway of the airport makes the best use of the existing corridor resources in route selection, creates a three-dimensional traffic system and releases the urban development space. "For example, in the section of National Highway 106, there is a subway under it, with National Highway 106 in the middle and the second expressway above the airport." The project leader introduced. The project also innovated the way of pipeline relocation. For the first time in Guangzhou expressway construction industry, the comprehensive pipeline relocation unit was selected by public bidding, and multiple pipeline relocation routes were optimized by design and construction general contracting, and all pipeline property rights units were organized to participate in the design scheme discussion, breaking the "fragmented" situation of pipeline relocation, which not only greatly reduced the amount of land occupation and house demolition, saved investment costs, but also provided orderly pipe network layout support for future road network improvement.Promote innovation and empower BIM technology to lead smart construction sites to build the second high-speed airport project. BIM technology is also widely used in site construction and management, effectively solving construction problems in complex environments. According to reports, BIM technology is based on three-dimensional digital technology, which combines the BIM model established in the early stage with the surrounding real terrain, environment and other data through multi-channel image fusion technology to generate a real digital virtual sand table of the project, and escorts the project construction by intelligent means. How to move the pipeline? The model predicts first. The airport second expressway project innovatively uses "GIS+BIM" technology to establish a virtual digital sand table, and generates a visual three-dimensional model of the invisible underground pipeline. "Through the BIM model, the pipeline relocation can be arranged in advance. For example, seeing the close relationship between the pipeline and the subway and finding the conflict point of the pipeline relocation will make the actual operation more organized." The project leader said. The northern section of the project involves the construction of G106 bridge pier, capping beam and steel box beam, as well as the prefabrication and erection of beam and slab. The project adopts BIM technology to build an all-round three-dimensional real-life model communication platform, observe the site construction in 360 degrees in real time, strengthen the deep interaction between the project company and the construction unit, realize the scientific, standardized and intelligent management of the project based on BIM technology, and speed up the progress of the project. With this technology, the SG08 contract section of the North Section of the Second Airport Expressway completed an output value of 80 million yuan in a single month, setting a new record for the monthly output value of the bridge standard. It is understood that,The research results of the project on BIM technology also won many honors, such as the third place in the BIM application category of bridges and tunnels in the 10th imagine cup Building Information Model (BIM) Application Competition. Expand the skill competition mode, and the provincial key project labor competition will boost the project construction. During the construction process, the northern section of the second expressway of the airport will also vigorously carry out the provincial key project labor competition to adapt to the development of the new era. By expanding the depth of labor competition and innovating the skill competition mode, the construction upsurge of catching up with learning will be set off in the whole project, which will effectively promote the high-quality and efficient construction of the project. It is understood that since 2017, the project has carried out a series of labor competition activities such as "attacking the city and pulling out the village", "taking root", "flowering results" and "making new achievements", with the goal of "model project, clean project and quality project". Through a series of skill competitions, such as steel bar welding and upsetting straight thread sleeve connection, experimental testing practice, engineering survey practice, New Jersey guardrail steel bar binding and pouring, and the appraisal of craftsmen’s construction teams, post experts (pacesetters), advanced collectives and individuals, technical exchanges and mutual promotion have been realized, and the simple production and physical labor competition has been upgraded into an intelligent and scientific research competition, and four advanced collectives and three winners of Guangdong May 1 Labor Medal have emerged.
