Academician of the Chinese Academy of Engineering
"played with drugs" for 29 years, saved countless people
in the fight against SARS, the "Ebola Terminator"
is considered to be the prototype of the doctor Chen in "Wolf Warrior 2"
January On the second day of the Lunar New Year on the 26th, Chen Wei, 54-year-old
, led the expert team to Wuhan
. Two days later (January 28), the new coronavirus (2019-nCoV) nucleic acid detection reagent was jointly developed by the Military Medical Research Institute and local companies. The box (RT-PCR fluorescent probe method) passed the emergency approval of the National Medical Products Administration and obtained the medical device registration certificate.
4 days later (January 30), the emergency tent-type mobile testing laboratory of the Academy of Military Sciences began to operate. The use of self-developed testing kits and automatic nucleic acid extraction technology have greatly shortened the nucleic acid testing time compared with the current time. Speed of diagnosis.
quickly
Anyone familiar with Chen Wei knows that this is her greatest feature.
walks fast, speaks fast, and works fast. This is a habit she has developed in her research career for more than 20 years, because she always feels that time is not enough. The fast pace of
even made many male colleagues around him embarrassed: "She has a very sharp mind, can handle many things at the same time, and always can't keep up with her rhythm."
became a female scientist, this is Chen Wei in student days Things never thought of.
Chen Wei was born in Lanxi City, Zhejiang Province in 1966.
Chen Wei has been a "child of someone else's family" since she was a child. Not only is she beautiful, she is also an excellent and stable "school bully".
In 1988, Chen Wei graduated from the Department of Chemical Engineering, Zhejiang University. He obtained the only qualification recommended by Zhejiang University to Tsinghua University and successfully entered Tsinghua University for a master's degree in biochemical engineering.
At this time, she didn't want to be a scientist.
Her long hair is fluttering, avant-garde and fashionable. Netizens yelled "first love face" when they saw her young photos.
Chen Wei is a lively person. Although she is a science student, she likes literature and dance. She often visits the student cafeteria dance party on weekends. Also the first batch of waitresses in the university cafe.
In 1990, an opportunity to obtain antibodies from the Academy of Military Medical Sciences made her understand this place. She was attracted by the cutting-edge topics and scientific research equipment here, and she had a strong desire to participate in it.
In 1991, Chen Wei, who graduated with a master's degree, made a choice: join the army and go to the Academy of Military Medical Sciences for scientific research. Many people do not understand her choice, because before that, she had signed a contract with a well-known biological company in the south. If she followed the previous plan, she would live a life of high-paying white-collar workers. My family and friends all think that a master's degree from Tsinghua University is equivalent to burying themselves in the army.
Chen Wei, who is independent and independent, insisted on her decision.
In 1998, 32-year-old Chen Wei graduated with a doctorate from the Academy of Military Medical Sciences. In the same year, she became a mother, but after only one month of maternity leave, she returned to the laboratory. In a few years, Chen Wei rarely went home before 12 o'clock and returned to the dormitory.
On the night of the New Year’s Eve, she took the time to see her in-laws. When she returned to the laboratory, she saw only one place of liquid. Watching the two-month cell experiment disappeared instantly, she stood alone in the laboratory and cried loudly. .
Gradually, Chen Wei began to lead major scientific research tasks and emerged.
In the spring of 2003, SARS broke out, schools were closed, entertainment venues closed, and the whole country fell into panic.
At the critical moment, 37-year-old Chen Wei was ordered to develop a vaccine to prevent the SARS virus. She spends days in the laboratory without weekends and holidays.
took care of the children to her husband Ma Yiming.
The two met on the train. Chen Wei, who was a graduate student of Tsinghua University at the time, was invited by a classmate to travel to Mount Tai, Shandong.
met Ma Yiming on the way. When he got off the bus, Ma Yiming asked Chen Wei for a phone call. Chen Wei, who was cheerful, said: It just so happened that we just installed a phone in our dormitory and told her number..
Ma Yiming, if you get a treasure, keep it in your heart.
Under Ma Yiming's pursuit, the two came together in 1992. After
got married, Ma Yiming took on most of the housework and relieved Chen Wei's worries about her busy scientific work. He refused to let her do housework, thinking it was a "waste" of her talents, because she did other things more valuable.
In 2003, Chen Wei's research institute took the lead in isolating a new type of coronavirus in China and identified the culprit of SARS
. She led the research team to risk their lives and contact the SARS virus at zero distance to conduct in vitro cell tests on the SARS virus. , To construct a new animal experimental model. Although the
team has a high-level biosafety laboratory, the corresponding protective clothing is not enough. Chen Wei's team insists on relying on the existing conditions and does not create conditions to do it.
According to conventional practice, people must go out and breathe out after working in a negative pressure laboratory for up to 5 hours at a time. However, in order to fight the epidemic, she and her colleagues ignored the severe headache caused by the negative pressure and oxygen deficiency in the laboratory and stayed in for eight or nine hours. In order to stay longer, before entering the laboratory, try not to eat or drink, and use adult diapers to reduce the frequency of coming out.
At the most critical time of the experiment, Chen Wei and the team members did not close their eyes in the laboratory for 48 hours, and finally got an exciting result: Thanks to the protection of interferon, the cells were safe and sound under the attack of the SARS virus. In subsequent large animal and clinical trials, Chen Wei and the team were isolated separately because they had zero-distance contact with high concentrations of the SARS virus every day.
For more than 100 days, Ma Yiming and his 4-and-a-half-year-old son could not see Chen Wei.
One day, someone told Ma Yiming that there might be scenes of Chen Wei in "Oriental Space" today. He and his son stared at the TV at home. As soon as the mother came out, the son rushed to kiss the TV. The careful Ma Yiming took it.
Chen Wei traveled to 83 “SARS” designated hospitals across the country to guide drug use and collect data among high-risk groups. Her efforts paid off. She verified the effectiveness of interferon in the shortest time.
On April 28, 2003, the "recombinant human ω interferon" developed by her and her team was approved by the State Food and Drug Administration and was allowed to enter the clinic.
In order to meet the urgent need, Chen Wei organized all staff in the room to work overtime to produce, and worked continuously for more than 20 days and nights outside the camp, so that the daily output of "recombinant human omega interferon spray" was quickly increased from the initial several hundred to two. Ten thousand. After
, she personally delivered more than 2,000 nasal sprays to Xiaotangshan Hospital in time. According to statistics, a total of 14,000 medical staff across the country have used the "recombinant human omega interferon spray" and other protective measures have been taken, without any infection. A reporter from
asked her: "Are you afraid to face the SARS virus every day?" Chen Wei blurted out: "Wearing this uniform means you should do all this." This year,
, she won " "2003 National Top Ten Outstanding Youth" won the "China Youth Science and Technology Innovation Outstanding Award".
In May 2008, the Wenchuan earthquake occurred.
Chen Wei served as the deputy leader of the disaster assessment team of the National Earthquake Expert Committee, organizing the compilation of "Post-earthquake Health and Disease Prevention 30 Questions and Answers" and "Health and Epidemic Prevention and Psychological Assistance Knowledge Handbook", risking aftershocks to lead the team into Sichuan to fight the "epidemic" Two months. After returning home from the disaster area,
immediately joined the expert team of the "Army Olympic Security Command Team" and successfully handled multiple suspected biological incidents.
Dancing with "Poison"
In 2004, Chen Wei turned his attention to the virus "Ebola" with the highest fatality rate.
In 2006, Chen Wei's team's "Recombinant Ebola Vaccine Project" was supported by the National "863 Program".
In 2014, a large-scale Ebola epidemic broke out in West Africa and spread rapidly. It spread to Europe and America, causing global panic.
In order to keep the epidemic out of the country, Chen Wei disregarded the difficulties and dangers and led a team to Africa. In 2014, the world's first new genetic vaccine against Ebola was successfully developed. Soon after, Chen Wei’s team obtained the permit for overseas clinical trials, realizing my country’s independent research and development of vaccines overseas."Zero" breakthrough in clinical trials.
In 2015, Chen Wei's team walked into Sierra Leone and started the second phase of clinical trials there, building a safety barrier for the people in the epidemic area, and demonstrating China's image as a big country capable of contributing wisdom to the health of the people of the world.
Someone asked her "What is Ebola?" "Who can you use for Ebola vaccine?" Chen Wei did not answer at the time.
Some people also said that if there was no Ebola outbreak in 2014, what you did was not done in vain.
"If the vaccine is not applied, I feel very fortunate, at least the people all over the world are safe. This thing is normal for us, my predecessors, the older generation of scientists, many people I don't know what they are doing all their lives , But I know that once the country or the army needs us to show our strength, we can always see the strength of the army, from SARS, bird flu, Wenchuan, Olympic security to Ebola."
In the 30 years of military service, in Chen Wei's view, it is always the pursuit of scientific research workers and the responsibility of soldiers to play first moves and take the initiative.
On the battlefield of biosecurity prevention and control, they are one of the first line. A colleague said to her, "Chen Wei, you should do less research on'devilish' topics", but she can't think of anthrax, plague, smallpox, Ebola, and other powerful microorganisms in her mind. Used in wars and terrorist attacks, which will bring disastrous consequences to the country and nation, she has a sense of mission and urgency in casting a "biological shield".
In July 2015, the General Logistics Department of the Chinese People's Liberation Army held a promotion ceremony for the rank of major general. Chen Wei, 49, became the only female officer promoted that day.
In 2016, Chen Wei was awarded the CCTV-10 "Top Ten Scientific and Technological Innovation Figures in China in 2015" for her outstanding contribution to the fight against Egypt. At the same time, Tu Youyou, who won the Nobel Prize in Physiology or Medicine for the discovery of artemisinin, was also selected. professor.
In November 2019, 53-year-old Chen Wei was elected as an academician of the Chinese Academy of Engineering.
has made important contributions in the fight against SARS and Ebola. Chen Wei is also regarded as a "seed player" in the "100-meter" race for the development of the new coronavirus vaccine. On the fifth day of
arriving in Wuhan, at Jinyintan Hospital, Chen Wei saw Dean Zhang Dingyu, who was suffering from frostbite and his wife was infected with the new coronavirus, but who was still on the front line. She said to Dean Zhang: I am very moved by your deeds.
Dean Zhang replied to her: each other.
At present, in the absence of vaccines and specific drugs, the plasma of recovered patients is the most accessible resource for clinical specific treatment. "Because traditional Chinese culture advocates recuperation after serious illnesses, many recovered patients in the past were unwilling to donate their plasma." Chen Wei said.
On January 31, with the "Letter on Requesting Assistance in Collecting Blood Samples from New Coronavirus Pneumonia Patients" issued by the Ministry of Science and Technology of the People's Republic of China, 22 recovered patients expressed their willingness to let experts test whether blood samples meet the standards for donating plasma. Some of them are weak and have difficulty even collecting blood. Chen Wei was very moved.
"I am a mother, a daughter, and a wife. I want my family to be healthy, and I also hope that everyone in the world is healthy." As a soldier,
has only two states, one is fighting and the other is preparing to fight. We are currently in the epidemic area, and we are going to fight, and we are preparing to fight because of our previous accumulation in scientific research, including technical reserves. We must mobilize the "soldiers" that have been keeping soldiers for thousands of days, and throw them into this special war at the fastest speed.
This is Chen Wei's attitude.
