CCTV News:WeChat official account, July 31st, 2008, WeChat released by Shanghai. In order to continuously consolidate the achievements of epidemic prevention and control, and find and control the epidemic risk as soon as possible, it was decided to carry out full-scale nucleic acid screening for streets (towns) with positive infection tracks in Jing ‘an District, Putuo District, Hongkou District, Yangpu District and Baoshan District and other administrative districts.

Each district should implement the territorial responsibility, reasonably organize open community nucleic acid sampling points, and carry out "three days and two inspections" from August 2 to August 4 (that is, complete two nucleic acid inspections within three days, at least 24 hours apart). Each district can arrange the screening time reasonably according to the actual situation of its own jurisdiction; It is necessary to fully launch and meticulously organize, and ensure that all personnel such as residential quarters, shops along the street, and guest (brigade) halls are included in the screening scope to ensure that no one is left behind. At the same time, routine screening on weekends is still carried out as planned.

All communities and units should strengthen the verification. During the screening period, the personnel in the above areas need to take nucleic acid samples within 24 hours to prove the communities (units and places).

The general public are requested to participate in nucleic acid screening and sampling in an orderly manner according to the arrangements of their towns and villages. During the sampling process, please do a good job of personal protection, wear masks in a standardized manner, and strictly keep the distance. Please also ask all towns, villages and units to do a good job in service guarantee.

　　On may 23,A large number of dead fish and shrimp appeared in Pukou section of Chuhe River in Nanjing, a first-class tributary on the left bank of the lower Yangtze River.. These days, the salvage of dead fish in the Nanjing section of the Chuhe River is still going on, and the foul smell of the water body has not been completely dispersed.What happened behind this?Let’s look at the investigation of the reporters at the reception desk.

　　01

　　Fly swarms! It stinks!

　　Dead fish in Nanjing section of Chuhe River are still being salvaged.

　　On May 25th, the work of salvaging dead fish continued. Along the way, the river gave off a pungent smell, with swarms of flies and foul smell. The villagers responsible for salvage told reporters,In the past two days, dead fish have been turning over the water surface, and the river is full of black. "It’s still dark, and I dare not wash my hands."

　　At noon on May 25, the reporter from the General Station went upstream along the Nanjing section of the Chuhe River and found that the work of salvaging dead fish along the coast continued.The river gave off a pungent smell along the way.Near Fuxing Culvert in Fuxing Wei, Yongning Street, Pukou District, Nanjing, the dead fish and mussels that have just been salvaged ashore are packed in more than a dozen white woven bags, with swarms of flies and foul smell.

　　The reporter saw at the scene that several nearby villagers, with tools such as net bags in their hands, were fishing for dead fish upstream along the Chuhe River. In the river, two people drive boats to salvage floating objects.

　　The villagers responsible for salvage told reporters that because the local maximum temperature exceeded 31℃ in these two days, dead fish kept turning over the water. Two days ago, the river was full of black, and it began to turn dark green on the 25th. The reporter saw near the Maozui Pumping Station in Chuhe River.Various impurities float in the river, and the black water body is still clearly visible.

　　Reporter:When did this happen?

　　Nearby villagers:It’s the 23rd.

　　Reporter:What was the water like on the 23rd? Is there any smell?

　　Nearby villagers:The water is black, not only black but also muddy. The pungent smell made us afraid to wash our hands.

　　It is understood that the Chuhe River is located between Jianghuai and is a first-class tributary on the left bank of the lower reaches of the Yangtze River. It originated in Liangyuan Town, Feidong County, Hefei City, and entered the Yangtze River in Liuhe District, Nanjing. The total length of the main stream is 269 kilometers, and the basin area is 7829.9 square kilometers.

　　Where does the foul-smelling water come from?

　　On the evening of May 23rd, the Ecological Environment Branch of Quanjiao County, Chuzhou City issued a statement saying that after the water quality of the Chuhe River was polluted, the local branch sluice and Xianghekou sluice were closed to intercept sewage, and emergency treatment and water quality monitoring were carried out.The reporter verified in many ways that after the pollution incident, the local investigation team has not yet been established.Anhui and Jiangsu are strengthening communication.

　　02

　　Reason disclosure!

　　The fire of hazardous chemicals caused pollutants to leak into the river.

　　The reporter learned from the insider that the abnormal water quality of the Chuhe River was related to the leakage of pollutants into the Chuhe River due to the fire of crude methanol, a hazardous chemical in the warehouse of Anhui Chuzhou Fuxin Petroleum Additives Co., Ltd. on May 7.

　　After continuous investigation for several days, the reporter learned from insiders that the water quality of the Chuhe River has been abnormal recently, which is related to the leakage of crude methanol fire pollutants from the warehouse of Anhui Chuzhou Fuxin Petroleum Additives Co., Ltd. into the Chuhe River.

　　At 7 o’clock on the evening of May 25th, the reporter from the General Desk, according to the instructions of the insider, rushed to the location of Fuxin Petroleum Warehouse and the third-phase standardized factory building on the east side of Jinger Road in Quanjiao Economic Development Zone for investigation. There are 6 workshops here, covering an area of 42 mu, which were completed in 2012. The workshops are owned by Quanjiao Parkson Metal Technology Co., Ltd. and are now leased to four local enterprises. Workshop 2, where a fire broke out, has been partially dismantled. Environmental monitoring personnel are taking sewage samples at the scene. There are still many plastic buckets filled with unknown liquid in the warehouse on the side. The air is filled with the pungent smell of chemicals.

　　The reporter found from the fire accident certificate issued by Quanjiao County Fire Rescue Brigade on May 24 that a fire broke out in the warehouse of Chuzhou Fuxin Additives Co., Ltd. at 7: 00 pm on May 7, and the Chuzhou Fire Rescue Detachment mobilized 30 fire engines and 140 fire rescuers for on-site disposal. The fire was extinguished at 0: 00 on May 8. After on-site investigation, the fire damaged the warehouse of Chuzhou Fuxin Petroleum Additives Co., Ltd., burned some goods and plastic barrels in the warehouse, and completely burned the tanker parked in the warehouse unloading crude methanol, with no casualties.

　　Dou Ping, Director of Ecological Environment Branch of Quanjiao County, Chuzhou City:There are mainly two kinds of storage materials, one is glycerol, whose chemical name is glycerol, and the other is molasses, which is a sugar substance. But the real fire was caused by the improper operation of the stevedores, that is, drivers of dangerous goods, in the process of unloading crude methanol, which led to the fire.

　　It is understood that the fire caused the destruction of No.2 factory building.A mixture of nearly 20 tons of crude methanol, a large amount of fire fighting foam, glycerin, molasses, etc.It flows into the flood discharge channel of the development zone through the side ditch next to the factory building, and enters the Chuhe River through the Garden Reservoir, Tuqiao Xihe River and Xianghe River. The reporter noticed that the trees near the scene of the incident turned yellow as a whole after being polluted, which was in sharp contrast with the surrounding green trees.

　　The reporter from the General Station learned in the Ecological Environment Branch of Quanjiao County, Chuzhou City that,The reason for the large area of dead fish in Chuhe River is related to the fire of crude methanol in the warehouse of Chuzhou Fuxin Petroleum Additives Co., Ltd. on May 7, which caused pollutants to leak into Chuhe River.

　　Dou Ping, Director of Ecological Environment Branch of Quanjiao County, Chuzhou City:According to our preliminary analysis and judgment, it is related to the fire of an enterprise in the development zone on May 7, which caused some material leakage in storage to be discharged into the water body with fire water and rainwater, which may be the main reason. It is also combined with the comprehensive formation of crayfish breeding tail water and concentrated backwater, as well as some weather reasons, such as high temperature and rain.

　　03

　　The staff at the gate reflected the abnormality of water body.

　　The relevant departments think that "no problem" is not taken seriously.

　　After the fire, the local eco-environmental department set up an earth dam in Huayuan Reservoir to block the polluted water. However, a heavy rain washed away the earth dam and the sewage entered the Garden Reservoir.

　　On may 20, the river water in the upper reaches of the sluice has been polluted. In this regard, the water conservancy bureau’s response is "by experience" and "no problem", so that the pollution problems that have been discovered have not been paid due attention and treatment.

　　After the fire broke out, the mixture of fire fighting foam, glycerin, molasses and crude methanol of hazardous chemicals flowed into the flood discharge channel of the development zone through the side ditch next to the factory building. The local eco-environmental department set up an earth dam more than ten meters long at Chuantang Road and Bridge in the upper reaches of Huayuan Reservoir, which is 3 kilometers away from the factory building, to block up the polluted water. At the same time, let enterprises assemble dozens of tank trucks from other places, extract thousands of tons of polluted water, box them or let enterprises transport them abroad for treatment.

　　The reporter walked along the river from the Garden Reservoir, followed the trail, and came to the Xianghekou Gate of the Yangtze River Diversion Project in Sima Mountain, Anhui Province. It is adjacent to the intersection of Xianghe River and Chuhe River. The staff told the reporter that on May 20, the upstream river under the sluice had obviously changed color and was polluted.

　　Wei Zhaohang, Deputy Director of Xianghekou Gate Management Office of Sima Mountain River Diversion Project in Anhui Province:The color is a little black, and the smell may be a little irritating.

　　Reporter:When this happens, is the gate open?

　　Wei Zhaohang, Deputy Director of Xianghekou Gate Management Office of Sima Mountain River Diversion Project in Anhui Province:In the closed state.

　　Dai Jinsong, Chief of Water Administration Section, Sima Mountain Diversion Project Management Office, Anhui Province:After discovering that the water body was abnormal, he (Wei Zhaohang) gave me a call and sent two photos. The water quality at the sluice was very poor and there were dead fish.

　　After reporting the abnormal situation of the water body to the management office of the Sima Mountain River Diversion Project, the staff of the Xianghekou Gate Management Office then rushed to the Hechang Office of Quanjiao County, but no one was seen. The staff reported the abnormal water body at the sluice to Yang Jun, a member of the party group of Quanjiao County Water Conservancy Bureau.

　　Wei Zhaohang, Deputy Director of Xianghekou Gate Management Office of Sima Mountain River Diversion Project in Anhui Province:Secretary Dai Chuanhua and Director Fang Chun from our institute went to Quanjiao Water Conservancy Bureau to reflect this situation.

　　Yang Jun, member of the Party Group of Quanjiao County Water Conservancy Bureau:On the 20th (Dai Chuanhua and Fang Chun), they asked me that the water in the Xianghekou sluice was a little black, and asked what the reason was. Honestly, I really don’t know.I can only rely on my experienceTell him that it may be just that shrimp (farming) changed water in May. Change the water in the shrimp field, and the water quality in the river is not good. In addition, a few days ago, the water level in the lower reaches of Xianghe River was relatively low, and it was also a waterway, in which boats were stirring. This happened in previous years. There should be no other situation, because I really don’t know what it is.

　　According to the reporter’s investigation, on May 20th, the People’s Government of Quanjiao County issued a letter to Chuzhou Water Conservancy Bureau, which mentioned that "in order to effectively protect the domestic water consumption of urban residents in Chuzhou City and Quanjiao County and the water consumption for agricultural production along the Weihe River embankment", it was requested to "arrange the Sima Mountain Management Office to start up and lift water", and on May 22nd, the Xianghekou sluice was opened to release water.

　　In this way, the "experience" and "no problem" of the relevant departments have made the pollution problems that have been discovered fail to get the attention and treatment they deserve.

　　Yang Jun, member of the Party Group of Quanjiao County Water Conservancy Bureau:Give me another one. To tell you the truth, I will retire in two months. I shouldn’t ask these things too much.

　　The reporter saw in the operation record book of the sluice management office of Xianghekou Gate in Sima Mountain River Diversion Project in Anhui Province that on the morning of May 18th, the sluice here had been completely closed. However, two days after the discovery of water pollution, at 10: 50 am on May 22, five holes in the seven-hole sluice of Xianghe Estuary were opened, and the sewage gathered in front of the sluice for two days entered the Chuhe River smoothly. This time, the water was released until 15: 50 on May 23, and the time was as long as 29 hours.

　　Wei Zhaohang, Deputy Director of Xianghekou Gate Management Office of Sima Mountain River Diversion Project in Anhui Province:This time, the water body was still black and smelly.

　　Huang Zhongfei, deputy director of Quanjiao County Water Resources Bureau:On May 23, it was said that there was public opinion, and it was found that there might be pollutants of unknown substances in the water body, causing the death of fish and shrimp. At that time, the Xianghe Gate was closed.

　　04

　　Lobsters died in a large area around abnormal water bodies.

　　Baixing hope water quality inspection

　　Department reply: No need.

　　This pollution incident not only caused a large number of fish and shrimp deaths in the Nanjing section of the Chuhe River, but also caused a large area of lobster deaths in Quanjiao, which brought huge losses to farmers. Some people reflected through Chuzhou 12345,The staff who claimed not to have participated in the problem solving became the "undertaker".

　　People are very worried about whether the sewage is toxic, and expect the water quality test results of the ecological environment department to give a professional answer, but Quanjiao County Ecological Environment Branch replied:It’s not necessary.

　　In the past few days, the reporter found in Jiangsu and Anhui that this pollution incident not only caused a large number of fish and shrimp deaths in the Nanjing section of the Chuhe River, but also caused a large area of lobster deaths in Quanjiao, which brought huge losses to farmers.

　　On the afternoon of May 26th, in Wugang Town, Quanjiao County, a villager told the reporter that the crayfish raised at home had died these days. At present, the villager and neighbors are afraid to raise crayfish with river water.

　　During the local visit, many villagers confirmed to reporters that river water pollution has had an impact on the local ecological environment and people’s lives. Among them, fish and shrimp death is the most obvious phenomenon.

　　Reporter:Can there be a phenomenon of large-scale death?

　　Villagers in Wugang Town, Quanjiao County:Yes, by the river.

　　Reporter:When did the mass death occur?

　　Villagers in Wugang Town, Quanjiao County:I’m afraid it was a few days ago, probably when there was polluted water.

　　For the difficulties caused by environmental pollution around us, some people reflected through the 12345 hotline in Chuzhou City.

　　The masses reported the problem through the hotline. Organizer: Did not participate in the handling.

　　During the visit, the reporter found that Chuzhou 12345 complained to the common people and was posted on the Internet by netizens. The content showed:

　　The 12345 hotline attached great importance to the problem that the water quality of Xianghe River in Laoguan Chencun Village, Xianghe Town, Quanjiao County was black and smelly, and immediately handed it over and urged the organizer to deal with it seriously. The feedback from Quanjiao County Government: The staff of the Environmental Protection Bureau visited the site recently, and the crayfish culture was concentrated on returning water to Xianghe River. In addition, the high temperature and no rainfall for a long time caused the water quality in some sections of Xianghe River to decline, and some of them were black and smelly, resulting in the death of fish and shrimp. No pollution sources such as enterprises and factories were found. Your report is true.

　　On May 26th, the reporter came to Quanjiao County Ecological Environment Branch of Chuzhou City to understand the situation. However, Yang Renyi, director of the office of Quanjiao County Ecological Environment Branch, the specific organizer mentioned in the hotline platform’s reply to the masses, told reporters that,He has never received any complaints from the masses forwarded by the hotline.

　　Reporter:Have you received any complaints about environmental protection from 12345, environmental hotline and 110 after the fire broke out?

　　Yang Renyi, Director of the Office of Ecological Environment Branch of Quanjiao County, Chuzhou City:No.

　　Reporter:But I saw a reply from Chuzhou 12345 about the problem that the water quality of Xianghe River in Laoguan Chencun, Xianghe Town, Quanjiao County was black and smelly, and the undertaker was Yang Renyi.

　　Yang Renyi, Director of the Office of Ecological Environment Branch of Quanjiao County, Chuzhou City:I didn’t reply. I’m not sure about it yet.

　　Reporter:Does that prove that this 12345 reply from Chuzhou is false?

　　Yang Renyi, Director of the Office of Ecological Environment Branch of Quanjiao County, Chuzhou City:It may be because the government’s 12345 platform is all on the government side, and it should be a unified reply from the government side. I am not sure about this.

　　Reporter:You just haven’t disposed of it?

　　Yang Renyi, Director of the Office of Ecological Environment Branch of Quanjiao County, Chuzhou City:Right, no.

　　Reporter:You are the organizer, that is, you have never participated in it from beginning to end?

　　Yang Renyi, Director of the Office of Ecological Environment Branch of Quanjiao County, Chuzhou City:Never participated.

　　How can a staff member who has not participated in problem solving become a "contractor"?The reporter further asked the Chuzhou municipal government for verification, but as of press time, he has not received a reply.

　　The reporter also found in the investigation that,The people are very worried about whether it is toxic to the sewage flowing into the Chuhe River.It is also expected that the water quality test results of the ecological environment department can give professional answers. With a series of questions, the reporter came to Quanjiao County Ecological Environment Branch to ask and got such a reply.

　　Dou Ping, Director of Ecological Environment Branch of Quanjiao County, Chuzhou City:I don’t see any laws and regulations that require toxicity analysis.

　　Reporter:So you didn’t do it?

　　Dou Ping, Director of Ecological Environment Branch of Quanjiao County, Chuzhou City:I really didn’t do it.

　　Reporter:Then, if water enters the river, is it toxic, and our environmental protection department doesn’t know?

　　Dou Ping, Director of Ecological Environment Branch of Quanjiao County, Chuzhou City:I don’t think it is necessary to do water for fire fighting.

　　At present, relevant departments in Jiangsu and Anhui are stepping up communication and coordination of this pollution incident.The reporter of the General Station will also continue to pay attention to the latest progress of the incident.

The emergence of "super bacteria" indifferent to all existing antibiotics is no longer just a doctor’s worry, but a fact.

According to The Paper’s report on January 17th, recently, the Centers for Disease Control and Prevention (CDC) published a case report-in Reno, Nevada, USA, a 70-year-old woman was infected with carbapenem-resistant enterobacteriaceae (CRE) and became resistant to 26 antibiotics available in the United States.

Carbapenem antibiotics are generally considered as the "bottom card" for human beings to fight bacteria at present. The emergence of "super bacteria" is because with the uncontrolled abuse of antibiotics, bacteria are resistant to antibiotics faster than the replacement of antibiotics.

Carbapenem-resistant Enterobacteriaceae

This woman lived in India for a period of time. Because of the thigh fracture and the infection of thigh bone and hip caused by it, she was treated in hospitals in India many times. In August 2016, the woman who had returned to the United States was diagnosed with systemic inflammatory response syndrome in a hospital in Reno. During the period, the attending doctor used 14 kinds of antibiotics, but the woman’s condition did not improve. Until the beginning of September 2016, the situation turned sharply and the sick woman died.

Only after the hospital sent it to the Centers for Disease Control and Prevention in the United States did it know that the bacteria infected by the woman were not only ineffective against 14 kinds of antibiotics, but were resistant to all the existing 26 kinds of antibiotics in the United States.This makes the doctor helpless.

After learning that the woman was infected with carbapenem-resistant Enterobacteriaceae, the local hospital took timely isolation measures and strictly screened the medical staff. Fortunately, the woman has been in an independent ward.

The bacteria infected by this woman are called "nightmare bacteria" because of "full drug resistance".If it is widely spread, the consequences will be unimaginable. The local hospital inspected all the people in the hospital during the period, but fortunately there was no sign of the spread of carbapenem-resistant Enterobacteriaceae.

Recently, however, a study published in the Proceedings of the National Academy of Sciences shows that the spread of carbapenem-resistant enterobacteriaceae may be going on in a secret way, because patients with this bacteria may have no symptoms.

The researchers extracted about 250 samples of carbapenem-resistant Enterobacteriaceae from patients in four hospitals in the United States. The analysis showed that the rich drug-resistant genes contained in the samples were easily exchanged among different strains. Although the researchers found no evidence of drug-resistant bacteria exchange, they saw many kinds of carbapenem-resistant Enterobacteriaceae bacteria. In the absence of any symptoms, drug-resistant bacteria may have spread covertly.

"Carbapenem-resistant Enterobacteriaceae bacteria are like invisible killers, because they don’t get sick as soon as they get infected like Salmonella," Tim Johnson, an expert on antibiotic resistance at the University of Minnesota in the United States, compared "superbacteria" to a faucet that drips slowly. "It doesn’t cause symptomatic diseases for a long time, but lurks in the body."

According to CNN, there are two types of carbapenem-resistant enterobacteriaceae, one is "New Delhi Metal-Beta-Lactamase (NDM)" and the other is "Klebsiella pneumoniae (KPC)", and the dead woman in Nevada was infected with NDM. Generally speaking, compared with NDM, there are more patients with KPC in the United States. As of January 6, 2017, there were 175 cases of NDM recorded by the US Centers for Disease Control and Prevention.

New Delhi metallo-β-lactamase type

"This case is very important because it tells us that even though this situation is rare, it still happened, which sounded the alarm for us." Randall Todd, director of the Department of Epidemiology and Public Health Prevention in the county where the woman lives, told the Huffington Post that this was the first time he had met a fully drug-resistant patient.

In fact, this is not the first case of "superbug" infection in the world or in the United States. In May 2016, US health officials reported that a 49-year-old woman with urinary tract infection in Pennsylvania was resistant to all known antibiotics. This is considered to be the first case of "superbug" infection in the United States. The woman had no experience of leaving the country within five months before the onset of the disease.

According to estimates by the Centers for Disease Control and Prevention, there are about 9,300 patients infected with "superbugs" in the United States every year, and about 600 of them die. A survey report by the British government shows that if people ignore the problem of antibiotic resistance, by 2050, it is estimated that 10 million people worldwide will die of "superbugs" every year.

Klebsiella pneumoniae type

In 2015, the World Health Organization (WTO) launched a global action plan, calling on countries to pay attention to drug resistance and ensure the rational use of antibiotics. However, in some countries, effective management mechanisms have not yet been established. In India, antibiotics are often used to treat diarrhea.

Superbacteria has become a global problem, and many infected people have returned to China after being infected in countries with backward sanitary conditions. In 2010, a Belgian man infected with superbugs died in Brussels, which was the first reported death of superbugs in the world. According to Agence France-Presse, the man was infected while being treated in a hospital in Pakistan. Hospitals are "storage tanks" for drug-resistant bacteria, and the number and variety of them are frequent places for "superbugs". In the same year, Japan confirmed for the first time that a male patient who returned to Japan from India was ineffective against most antibiotics.

For ordinary people, what are the ways to protect themselves in the face of "super bacteria"? Washing hands frequently, getting vaccinated and eating safe food can keep you away from "super bacteria" to a certain extent. Wash your hands frequently, especially. This advice, which has been hung in your mouth since childhood, is an effective way to prevent infection with "super bacteria". However, the above methods only deal with the spread of "super bacteria", and cautious and restrained use of antibiotics is the source.

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.

□ Our reporter Mei Jianfei Tian Mochi

We will make greater efforts to build a modern transportation infrastructure system. This year, Jiangsu will ensure that the investment in transportation infrastructure construction is 220 billion yuan. Focusing on "networking, supplementing the network and strengthening the chain", we continue to expand effective investment and strive to improve the efficiency of the comprehensive transportation network. Since the beginning of the year, a large number of major projects have been accelerated. Since March 12, reporters have visited the construction sites of several major transportation projects in the province, and the builders are full of enthusiasm and enthusiasm everywhere.

Railway construction is fully powered.

At present, the Shanghai-Suzhou-Lake Railway is undergoing track-laying operation. It is expected that the track-laying construction of the whole line will be completed by the end of June, and then it will be transferred to the stage of static acceptance, joint debugging and joint testing, and it will be ready for operation by the end of this year. At the same time, projects such as the high-speed railway along the north river, the Tongsu Jiayu-Yong high-speed railway, the Ninghuai intercity railway, the second phase of the Shanghai-Suzhou railway, the Weifang-Suzhou high-speed railway, and the Shangyuanmen river-crossing passage are progressing at full speed.

Facing the warm spring breeze, I walked into the construction site of Suzhou South Railway Station and saw a fiery scene. With the roar of the machine, the workers were busy.

"This year is the closing year of the construction of Suzhou South Railway Station. In order to ensure the progress, more than 1,000 workers from the project department quickly assembled after the Spring Festival. Everyone put into construction with full spirit, and multi-type work, multi-regional crossover operation and simultaneous construction." Wang Jianwei, chief engineer of the underground space of Suzhou South Railway Station of China Railway 14th Bureau, introduced that the internal space of Suzhou South Railway Station is divided into four floors: the lowest level is the intercity railway of the water town tourist line, and the construction has been completed; The second floor is the sinking square, and the floor and roof of the main structure are under construction; The third floor is the Shanghai-Suzhou-Lake Railway, and track-laying operations are under way; The fourth floor is the Tongsu Jiayong Railway, and the construction is expected to be completed in May.

At present, the pace of high-speed rail construction along the north river is accelerating. "Before the Spring Festival, we have completed 67 holes of girder erection. Since entering the market after the festival, the workers have immediately invested in the new year’s construction tasks. At present, the construction of girder erection has been carried out steadily. " Cheng Huaizhi, head of the girder erection branch of the Shanghai-Nanjing section of the high-speed railway along the Yangtze River in the 11th Bureau of China Railway, said, "This year, it is planned to erect 347 holes of box girder, and the team will strive for perfection to ensure good quality and complete the girder erection task of the tender section safely, smoothly, orderly and efficiently."

The total investment of the third bid in front of the Shanghai-Nanjing section of the high-speed railway along the north river is 3.344 billion yuan. The main construction contents include 20.47 kilometers of the main line of the bridge project and 2.56 kilometers of the subgrade project. "Since March, 1500 cubic meters of concrete has been poured every day. At present, the bridge pile foundation project has been completed by more than 70%, the pile cap has been completed by about 50%, and the subgrade project has been completed by 35%. " Wang Xue, secretary of the Third Bid Project Department along the North River of China Railway 24th Bureau, said that according to this progress, the box girder erection will be carried out in June this year, and the bridge pile foundation and subgrade works will be completed before the end of the year. It is expected that the girder erection will be completed in June 2025.

The second phase of Shanghai-Suzhou Railway, starting from Taicang Station and ending at Situan Station, is an important part of the coastal passage in the "eight vertical and eight horizontal" high-speed rail network planned by the national medium and long-term railway network. "At present, 1,100 cubic meters of concrete is poured every day, 80% of bridge bored piles are completed, 50% of bridge caps are completed, and the total construction period is about 30%." Qian Jing, secretary of the Party branch of the Shanghai-Suzhou Railway Project Department of the 24th Bureau of China Railway, said that by the end of this year, 80% of the subgrade works and 80% of the bridge works should be completed to ensure the smooth erection of the main precast beam. It is expected that the main structure of the bridge and subgrade will be completed in the first half of next year.

The construction of river crossing channel is changing with each passing day.

Since last year, 10 river-crossing passages in the province have been under construction at the same time. According to the plan, the Longtan Yangtze River Bridge will be built this year, and efforts will be made to build the Xianxin River Crossing Channel. At present, new progress has been made in the construction of Changtai Yangtze River Bridge, Zhangjinggao Yangtze River Bridge, Jiangyin Jingjiang Yangtze River Tunnel and Haitai Yangtze River Tunnel.

At the construction site of Haitai Yangtze River Tunnel, the first tunnel of Wanli Yangtze River, workers and mechanical vehicles operate in an orderly manner. "The construction of the foundation pit enclosure structure in the Jiangbei section of the tunnel has been completed, and the earthwork excavation, steel support erection and main structure construction are being accelerated to provide favorable conditions for the subsequent shield machine to enter the site." Cui Jia, executive deputy commander of Haitai Yangtze River Tunnel Construction Command of Provincial Communications and Construction Bureau, said that it is expected that all the main structures of the foundation pit in Jiangbei section and all the enclosure structures of the foundation pit in Jiangnan section will be completed by the end of the year.

The construction of Changtai Yangtze River Bridge has new changes every day. Two "diamond-shaped" towers with a height of 350 meters stand in the middle of the Yangtze River. With the blessing of the towers, the stay cables and steel truss beams form two huge "umbrellas", which seem to be suspended above the Yangtze River, which is very spectacular. "The main channel bridge is carrying out large-section steel truss girder hoisting and stay cable hanging." Li Zhen, on-site commander of Changtai Yangtze River Bridge Construction Command of Provincial Communications and Construction Bureau, said that this year the bridge will be closed and ancillary works such as pavement, traffic safety, electromechanical and greening will be carried out.

At the construction site of the north approach bridge of Longtan Yangtze River Bridge, the sound of machinery and metal instruments is endless. On the river surface, the cable-crossing crane effectively lifted the steel box beam to the sling position, and the hoisting construction of the main bridge steel beam proceeded smoothly, making a step-by-step progress towards the completion goal this year.

"Hanging beam is a key link in the construction of the superstructure of the bridge, which requires precise construction monitoring and skilled operation cooperation." Hu Yao, on-site commander of the Longtan Yangtze River Bridge Construction Command of the Provincial Communications and Construction Bureau, said that now everyone is working hard to catch up with the construction period and progress on the premise of ensuring safety and quality. At present, the north approach bridge of Longtan Yangtze River Bridge is undergoing steel beam welding and bridge deck erection, and the south approach bridge is undergoing ancillary works installation. The main bridge has entered the second stage of steel box girder hoisting, and the bridge closure is expected to be realized in April.

On March 13th, at the construction site of No.3 main tower pier of Chongqi Gongtie Yangtze River Bridge, workers were binding the steel bars of the pile caps to prepare for the concrete pouring of the first pile cap before the end of March. This indicates that after the bottom sealing construction of the steel cofferdams of No.3 and No.4 main piers of Chongqi Gongtie Yangtze River Bridge, which was built by China Railway Bridge Bureau, the double main piers on the water entered the stage of pile cap construction.

Speed up highway construction in "spring"

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.
