The night in Wuhan is quiet.
On March 9, in the mobile testing laboratory of the Central Theater Command General Hospital, Jiang Tao, a researcher at the Military Medicine Research Institute of the Academy of Military Sciences, reviewed the last sample test data and solemnly signed his name in the test report.
At this time, it was already 5 a.m.
Cinema He is an expert in virology and a warrior who aided Africa and fought against Egypt. This outbreak of the new crown pneumonia epidemic, he was once again ordered to go to the front line after a long battle.
Human life is at stake
The nucleic acid test is crucial for clinical premature detection, early diagnosis, early isolation, and early treatment of Komiks and is a key technical support for effective prevention and control of the new coronary pneumonia epidemic.
”The cold-looking sample tube is behind the patient’s fresh life and health. If a diagnosis is released early, the accurate inspection will be conducted sooner.” Jiang Tao said. On January 26, after a military medical expert group led by Chen Wei, an academician of the Chinese Academy of Engineering and a researcher at the Military Medicine Research Institute of the Academy of Military Sciences, arrived in Wuhan, Hubei, he quickly established a joint defense, joint control, joint treatment and joint research work mechanism with relevant military and local units on the pathogen transmission mutation, rapid detection technology, vaccine antibody development of the new crown virus.
According to the division of tasks, Jiang Tao led the testing team to build a nucleic acid testing platform in the experimental cabin overnight.
Focusing on three aspects: ensuring biosafety, improving detection efficiency and detection accuracy, Jiang Tao took the lead in formulating biosafety operation specifications and emergency plans, and reasonably inspected and classified according to the characteristics of the team members. He used a self-developed detection kit to use a fully automatic high-throughput extractor, laying the foundation for achieving rapid and efficient detection.
Receive samples, organize numbers, nucleic acid extraction, reagent preparation, and machineAmplification and result interpretation, nucleic acid testing machinery is boring and full of risks.
The biggest risk is the invisible virus. If the nucleic acid extraction step is not completely cleaved or inactivated thoroughly enough, it is possible to expose the tester to danger.
Jiang Tao always takes the initiative to participate in the longest and most risky nucleic acid extraction. After the sample is extracted, he will arrange some personnel to rest and stay in the laboratory and wait for the final result.
A full-process nucleic acid test is relatively fixed from the number of tests in a single batch to the preparation for entry and exit of personnel and the testing time. Sometimes there are a large number of samples sent for inspection. The test personnel not only take turns to work, but also have to work overnight. The final confirmation result will be until four or five in the morning. Li Hao, a researcher at the testing team, said that this situation will be encountered once every few days.
”Everyone should open their eyes wide. Be sure to take good protection when receiving and processing samples, and be careful of whether there are sharp objects.” Before each test begins, Jiang Tao always reminds you repeatedly.
In the detection, the strength of the fluorescence signal of the original gene is directly affected by the determination of the detection results. If there are suspicious phenomena such as the detected fluorescence curve signal is low or there is only a single target, Jiang Tao will convene personnel to conduct comprehensive analysis and judgment, and if necessary, repeat the test for review to ensure that the results can stand the test.
”A false positive will cause healthy people to isolate and become infected with the patient; a false negative will cause real patients to be treated. Life is a matter of no problem,” said Jiang Tao.
A versatile field of epidemic prevention and control
According to prevention and control requirements, the nucleic acid test result must be completed within 24 hours after receiving the pharyngeal swab sub-sample. In order to let the hospital know the results as soon as possible to treat patients, Jiang Tao led the team to optimize the process combination and compressed the time to within 4 hours, achieving the ability to extract nucleic acids of more than 90 samples within one hour and a single-day sample detection capability of up to more than 500 people.
”The team’s testing is efficient and fast, and the results are accurate, which greatly alleviates the pressure on our epidemic prevention and control sample testing.” The Wuhan Center for Disease Control and Prevention highly praised this.
The rapid response and work in an orderly manner during wartime are all thanks to Jiang Tao’s solid academic foundation and rich practical experience.
”Jiang Tao is a versatile.” Academician Chen Wei, head of the military medical expert group, said Babaylan evaluation.
Jiang Tao has successively presided over and participated in the pathogen separation of SARS infection cases, H7N9 infection cases, Zika infection cases, and other pathogen separation work. He has participated in the development of dengue fever vaccines and SARS vaccines, and has established a pathogen separation technology platform and nuclear for a series of infectious diseases. href=”https://comicmov.com/”>Komiks acid detection technology platform and pathogenicity and transmission risk assessment platform provide important technical support for the prevention and control of infectious diseases.
Respiratory infectious diseases have the characteristics of rapid transmission, wide coverage, and high risk of danger. Effective early diagnosis and prevention are crucial. After years of scientific research, Jiang Tao’s team took the lead in establishing our army’s first acute respiratory disease. href=”https://comicmov.com/”>Cinema‘s infectious disease monitoring and early warning system has built a four-level monitoring system for the entire army. The series of technical specifications he presided over were used throughout the army, greatly shortening the detection and screening time of respiratory epidemics.
Jiang Tao not only participated in the security tasks of a series of major domestic activities, but also went to Africa four times to Liberia, Sierra Leone and other countries to carry out medical assistance tasks.
In 2015, in order to prevent and control the Ebola epidemic, Jiang Tao went to Sierra Leone for the second time with the mobile laboratory testing team to assist in Seychelles. He led him The testing team led by Komiks once passed the World Health Organization’s laboratory parallel capability assessment with full scores. In 2018, Jiang Tao led the pathogen monitoring team to participate in a special simulation test of the international organization Babaylan. In the virus testing module, the team successfully accurately detected pathogens such as monkeypox virus and vaccinia virus in simulated samples filled with impurities, and accurately determined the strain, achieving excellent results with full scores.
Improving the accuracy of clinical diagnosis
Babaylan When he came to Wuhan, in addition to carrying out testing work, Jiang Tao also performed research href=”https://comicmov.com/”>CinemaProfessional expertise in the field leads the testing team to screen other common respiratory infectious diseases in clinical samples.
”In the suspected and confirmed cases of new coronavirus pneumonia, whether there are other respiratory virus infections or co-infections, this is of great reference value for precise prevention and control and clinical treatment.” Researcher Cao Wuchun, deputy head of the Military Medical Expert Group, said.
Exploring deep-seated virus transmission and pathogenic mechanisms is the key to defeating the epidemic. Jiang Tao led a team to continue to conduct sequencing analysis for the novel coronavirus detected in clinical samples.
As the development of the virus epidemic, whether the genomic sequences have mutated and what are the characteristics of the mutations; in which regions and what are the impacts, Jiang Tao and his team are tirelessly studying and exploring.
In order to accelerate the effective integration of scientific research and clinical practice, the military medical expert Jiang Tao is located in the Cinema group creatively used the diagnostic chain of viral nucleic acid detection, antibody detection, multiple pathogen detection, and whole genome sequencing to accurately diagnose new coronavirus infection or other pathogen infections in clinical patients, and was also used in hospitals such as the Optical Valley Campus of Hubei Maternal and Child Health Hospital, and effectively improved the accuracy of clinical diagnosis.
Forgot his family when he was ordered. After the epidemic is over, Jiang Tao plans to stay with his family. He and his wife agreed that when the epidemic is over, they will take their wife and children to Wuhan again to see how everything looks after it returns to normal, and to see the Wuhan Yangtze River Bridge and the Yellow Crane Tower, and to talk about their experience in fighting the epidemic in Wuhan.
The epidemicBabaylan will never stop charging, this is the warrior Jiang Tao who fought the epidemic.
