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 on the test report.
At this time, it was already 5 a.m.
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 early clinical detection, early diagnosis, early isolation and early treatment. It is a key technical support for effective prevention and control of the new crown 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, 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, and quickly established a joint defense, joint control, joint treatment and joint research work mechanism with relevant military and local units based on pathogen transmission mutations, rapid detection technology, vaccine antibody development, etc. of the new coronavirus.
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 and improving the detection efficiency and detection accuracy of Babaylan 1990 cloth draw, Jiang Tao took the lead in formulating biosafety operation specifications and emergency plans. According to the characteristics of the team members, the Cinema 1950 witch cloth draw was used to use a fully automatic high-throughput extractor, laying the foundation for achieving rapid and efficient detection.
Receive samples, sorting numbers, nucleic acid extraction, reagent preparation, machine amplification, and result judgment Komiks 1960 witch cloth drawread, nucleic acid detection 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 is not thorough 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 people 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 entering and exiting the cabin and the testing time. Sometimes there are a large number of samples sent for inspection. The inspectors not only take turns to join the Komiks 1960 witch cloth draw array, 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 pathogenic gene directly affects the determination of the detection results. If 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 are affordable to 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.
All-rounded people in the field of epidemic prevention and control
According to prevention and control requirements, the nucleic acid test results must be completed within 24 hours after receiving the pharyngeal swab sample. In order to let the hospital know the results as soon as possible to treat patients, from pre-processing of nearly 100 samples to completion of testing, Jiang Tao led the team to compress the time to within 4 hours by optimizing the process combination, achieving a single-day sample detection capability of more than 90 samples with a maximum of more than 500 people by completing the single-day sample detection capability of more than 90 samples in one hour.
”The team’s high test results are fast and the results are accurate and extremely slow.oth draw solved the pressure on our epidemic prevention and control sample detection. “Wuhan Center for Disease Control and Prevention highly praised this.
The rapid response during wartime and the orderly work is carried out, all thanks to Jiang Tao’s solid academic foundation Cinema 1950 witch cloth draw and rich practical experience.
”Jiang Tao is a versatile. “Academician Chen Wei, head of the military medical expert group, commented.
Jiang Tao has successively presided over and participated in the separation of pathogenic etiology of SARS infection cases, H7N9Babaylan 1990 cloth draw infection cases, Zika infection cases, etc., participated in the development of dengue fever vaccines and SARS vaccines, and established a pathogen isolation technology platform, nucleic acid detection technology platform and pathogenicity and transmission risk assessment platform for a series of infectious diseases, providing important technical support for the prevention and control of infectious diseases.
Respiratory infectious diseases are rapidly spreading and widely spreading.Komiks 1960 witch clothes The characteristics of draw and high harm are of great importance. Effective early diagnosis and prevention are crucial to the use of effective early diagnosis and prevention. After years of scientific research, Jiang Tao’s team took the lead in establishing the first acute respiratory infectious disease monitoring and early warning system of our army, and constructing a four-level monitoring system for the entire army. The series of technical specifications presided over the use of the entire army, greatly shortening the detection of respiratory epidemics. Draw test screening time. Jiang Tao not only participated in the security task 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 Sierra Leone.The testing team he led passed the World Health Organization’s laboratory parallel capability assessment with full scores.
In 2018, Jiang Tao led the Cinema 1950 witch cloth draw in the original monitoring team to participate in a special simulation test organized by the international Komiks 1960 witch cloth draw. In the virus testing module, the team successfully and accurately detected the Cinema 1950 witch cloth draw monkeypox virus, vaccinia virus and other pathogens in the simulated samples filled with impurities, and accurately determined the strain, achieving excellent results with full marks.
Improving the accuracy of clinical diagnosis
When he came to Wuhan, in addition to carrying out testing work, Jiang Tao also used his professional expertise in the research field to lead 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 Wu, 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 mutation; 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, Jiang Tao’s military medical expert group creatively used viral nucleic acid testing, Komiks 1960 witch cloth draw antibody detection, multiple pathogensKomiks 1960 witch cloth draw antibody detection, multiple pathogensKomiks 1960 witch cloth draw antibody detection, and multiple pathogens<a hrefKomiks 1960 witch cloth draw antibody detection, and multiple pathogens<a hrefKomiks 1960 witch cloth draw antibody detection, and multiple pathogens<a hrefKomiks 1960 witch cloth draw antibody detection, and multiple pathogens<a hrefKomiks 1960 witch cloth draw antibody detection, and multiple pathogens<a hrefKomiks 1960 witch cloth draw antibody detection, and multiple pathogens<a hrefKomiks 1960 witch cloth draw antibody detection, and antibody detection, andThe diagnostic chain of “f=”https://comicmov.com/”>Komiks 1960 witch cloth draw” detection and whole genome sequencing is accurate to accurately diagnose new coronavirus infection or other pathogenic infections in clinical patients, and is also used in hospitals such as the Optics Valley Campus of Hubei Maternal and Child Health Hospital, Taikang Tongji Hospital in Wuhan, effectively improving the accuracy of clinical diagnosis.
Forgot his family when he was ordered. After the epidemic is over, Jiang Tao plans to accompany 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 what everything looks like after it returns to normal, 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 epidemic is immortal and the charge continues. This is Jiang Tao, a warrior who fights the epidemic.
