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 at Cinema 1950 witch cloth draw and a warrior who is the “Komiks 1960 witch cloth draw” in the war in Africa. 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 and accurate inspection is required
Nucleic acid testing is crucial for early clinical detection, early diagnosis, early isolation and early treatment, and is a key technical support for effective prevention and control of the new crown pneumonia epidemic.
”The cold-looking sampleBabaylan 1990 cloth draw is behind the patient’s living 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.
Following the three aspects of ensuring biosafety, improving detection efficiency and detection accuracy, Jiang Tao took the lead in formulating biosafety operation specifications and emergency plans, reasonably divided the labor according to the characteristics of the team members, and using a self-developed testing kit to adopt a fully automatic high-throughput extractor, laying the foundation for achieving rapid and efficient detection.
Receiving samples, sorting numbers, nucleic acid extraction, reagent preparation, machine amplification, and result interpretation, the 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?=”https://comicmov.com/”>Babaylan 1990 cloth draw If thorough enough, it is possible to expose the detector 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 entering and exiting the cabin and the testing time. Sometimes there are a large number of samples sent for inspection, and the inspectors 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 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, etc., etc., Jiang Tao will convene the Cinema 1950 witch cloth draw personnel for 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 result in a real delay in the treatment of patients. 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, 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 inspection is efficient and fast, and the results are accurate, which greatly alleviates the pressure of testing our epidemic prevention and control samples.Babaylan1990 cloth draw“Wuhan Municipal Center for Disease Control and Prevention highly praised this.
Fast response during wartime and orderly work is 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, commented. Jiang Tao has successively presided over and participated in the separation of pathogenic etiology such as SARS infection cases, H7N9 infection cases, Zika infection cases, etc., participated in the research and development of dengue fever vaccines and SARS vaccines, and established a pathogen isolation technology platform for a series of infectious diseases, a nucleic acid detection technology platform for a series of infectious diseases. Draw risk assessment platform provides important technology for infectious disease prevention and control. Draw support.
Respiratory infectious diseases have the characteristics of rapid transmission, wide coverage and great harm. 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 infectious disease monitoring and early warning system, constructing a four-level monitoring system for the entire army, and presiding on the use of a series of technical specifications 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 moved with the support of the PassageCinema 1950 witch clothes The test team of the draw laboratories went to Sierra Leone for the second time. The testing team led by him passed the World Health Organization with full marks.The laboratory is organized by h cloth drawKomiks 1960 witch cloth draw‘s ability assessment.
In 2018, Jiang Tao led the pathogen monitoring team to participate in a special Babaylan 1990 cloth draw simulation test by an international organization. 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 marks.
Improving the accuracy of clinical diagnosis
Cinema 1950 witch cloth draw When he came to Wuhan, in addition to carrying out testing work with Komiks 1960 witch cloth draw, 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 COVID-19, whether there are Komiks 1960 witch cloth draw in other respiratory virus infections or co-infections, which 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. In response to the novel coronavirus detected in clinical samples, Jiang Tao led his team to continue to conduct sequencing analysis.
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, Jiang Tao’s military medical expert group creatively used viral nucleic acid detection, antibody detection, multiple pathogen detection, and whole genome sequencingCinema 1950 witch cloth drawThis diagnostic chain accurately diagnoses clinical patients with Babaylan 1990 cloth drawThe new coronavirus infection or other pathogen infection, and is used in the Optical Valley Campus of Hubei Maternal and Child Health Hospital, Taikang Tongji Hospital and other hospitals 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 ended, they would take their wife and children to Wuhan again to see what everything would look like after it returned to normal, look at the Wuhan Yangtze River Bridge and the Yellow Crane Tower, and talk about the experience of fighting the epidemic in Wuhan.
The epidemic is immortal and the charge continues. This is Jiang Tao, a warrior who fights the epidemic.
