1Subtyping of type A influenza by sequencing the variable regions of HA gene specifically amplified with RT-PCR显示文摘The outbreak of a novel influenza A(H1N1) virus across the globe poses a threat to human health.It is of paramount importance to develop a rapid,reliable and inexpensive diagnostic procedure.Based on the bioinformatic information from public database,primers specific for influenza A virus surface protein haemagglutinin(HA) of several subtypes(including H1,H2,H3,H5,H7 and H9) were designed.Primer-specific PCR products were subjected to sequencing for accurately distinguishing H1 and H3 subtypes from others.This sequencing-based detection method will not only be applied to rapid detection and simultaneous subtype identification of new influenza A virus H1N1,but also provide the strategies to monitor other new types ofinfluenza virus with explosive potential.YAN An DING GuoHui ZHOU ZhenFeng DONG Hui ZHANG YaKun ZHU Lei HE YunGang ZHANG GuoQing LI YiXue SUN Bing HUANG Zhong LAN Ke JIN Li WANG HongYan WANG XiaoNing YANG Zhong ZHONG Yang DAI JianXin GUO YaJun WANG Hao CHE XiaoYan WU Fan YUAN ZhenGan ZHANG Xi CAO ZhiWei ZHOU XiaoNong ZHOU JiaHai MA ZhiYong TONG GuangZhi ZHAO GuoPing JIN WeiRong XIONG Hui 2009Chinese Science Bulletin2009,54,13:3
2Escaping alveolar macrophage endosomal retention explains massive expansion of SARS-CoV-2 delta variant显示文摘Dear Editor,Genetic variant Delta(B.1.617.2)of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),which possesses a remarkable ability to transmit and spread,is currently becoming predominant worldwide.Despite its great harm to human beings,how the Delta variant with T478K,P681R and L452R mutations achieves its ultrafast spread remains elusive.Entry of SARS-CoV-2 into host cells is mediated by a rapid enzymatic hydrolysis.Zhenfeng Wang Yabo Zhou Linlin Bao Dan Li Jiadi Lv Dianheng Wang Shunshun Li Wei-Min Tong Jiangning Liu Chuan Qin Bo Huang 2022Signal Transduction and Targeted Therapy2022,7,1:1
3ACE2 expression is regulated by AhR in SARS-CoV-2-infected macaques显示文摘During the current outbreak of coronavirus disease 2019(COVID-19)caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),more than 115 million people have been infected,and 2.5 million have died.1,2 Despite such great harm to human health,the pathogenesis of COVID-19 remains unclear.As the first step in the pathogenetic process,viral entry is mediated by the binding of the SARS-CoV-2 surface spike(S)protein to angiotensin-converting enzyme 2(ACE2)on host cells,such as lung epithelial cells.As an alternative to S protein-blocking strategies,manipulating host cell ACE2 expression may exert an inhibitory effect on SARS-CoV-2 infection.However,the molecular mechanism regulating ACE2 expression remains unclear.Jiadi Lv Pin Yu Zhenfeng Wang Wei Deng Linlin Bao Jiangning Liu Fengli Li Qiangqiang Zhu Nannan Zhou Qi Lv Guanpeng Wang Shunyi Wang Yabo Zhou Jiangping Song Wei-Min Tong Yuying Liu Chuan Qin Bo Huang 2021Cellular & Molecular Immunology2021,18,5:1
4SARS-CoV-2 treatment effects induced by ACE2-expressing microparticles are explained by the oxidized cholesterolincreased endosomal pH of alveolar macrophages显示文摘Exploring the cross-talk between the immune system and advanced biomaterials to treat SARS-CoV-2 infection is a promising strategy.Here,we show that ACE2-overexpressing A549 cell-derived microparticles(AO-MPs)are a potential therapeutic agent against SARS-CoV-2 infection.Intranasally administered AO-MPs dexterously navigate the anatomical and biological features of the lungs to enter the alveoli and are taken up by alveolar macrophages(AMs).Then,AO-MPs increase the endosomal pH but decrease the lysosomal pH in AMs,thus escorting bound SARS-CoV-2 from phago-endosomes to lysosomes for degradation.This pH regulation is attributable to oxidized cholesterol,which is enriched in AO-MPs and translocated to endosomal membranes,thus interfering with proton pumps and impairing endosomal acidification.In addition to promoting viral degradation,AO-MPs also inhibit the proinflammatory phenotype of AMs,leading to increased treatment efficacy in a SARS-CoV-2-infected mouse model without side effects.These findings highlight the potential use of AO-MPs to treat SARS-CoV-2-infected patients and showcase the feasibility of MP therapies for combatting emerging respiratory viruses in the future.Zhenfeng Wang Jiadi Lv Pin Yu Yajin Qu Yabo Zhou Li Zhou Qiangqiang Zhu Shunshun Li Jiangping Song Wei Deng Ran Gao Yuying Liu Jiangning Liu Wei-Min Tong Chuan Qin Bo Huang 2022Cellular & Molecular Immunology2022,19,2:1

6Airway administration of bisphosphate and dexamethasone inhibits SARS-CoV-2 variant infection by targeting alveolar macrophages显示文摘Dear Editor,Alveolar macrophages(AMs)are among the first immune cells to encounter SARS-CoV-2 during an infection due to their abundant numbers and physical location in the lungs.Thus,the reaction of AMs to SARS-CoV-2 has a profound impact on the outcome of the infection.In most cases,AMs can release cytokines and prime adaptive T-and B-cell immune responses to resolve the infection.Zhenfeng Wang Yabo Zhou Linlin Bao Dan Li Jiadi Lv Dianheng Wang Shunshun Li Jiangning Liu Chuan Qin Wei-Min Tong Bo Huang 2022Signal Transduction and Targeted Therapy2022,7,5:1

15Multi-Layer Tree Hierarchical Architecture Based on Web Service显示文摘To solve the problem of the information share and services integration in population information system, we propose a multi-layer tree hierarchical architecture. The command (Web Service Call) is recursively multicast from top layer of tree to bottom layer of tree and statistical data are gathered from bottom layer to top layer. We implemented the architecture by using Web Services technology. In our implementation, client program is the requestor of Web Services, and all leaf nodes of the last layer are only the provider of Web Services. For those nodes of intermediate layers, every node is not only the provider of Web Services, but also the dispatcher of Web Services. We take population census as an example to describe the working flow of the architecture.TONG Hengjian LI Deren ZHU Xinyan SHAO Zhenfeng 2006Wuhan University Journal of Natural Sciences2006,11,3:0
16Analysis of Microstructure of Reactor Pressure Vessel Steel due to Thermal Aging Effect by Small-angle Neutron Scattering显示文摘Reactor pressure vessels are of great importance for nuclear power safety and play an extremely important role in the safe operation of reactors and in preventing nuclear leakage.As material microstructure probe,neutrons have the advantages of high penetrability,ability to distinguish between adjacent nuclide and sensitivity to magnetism.The small-angle neutron scattering can accurately obtain the size distribution,volume fraction and composition of the defects of the nanosized copper clusters in the pressure vessel steel matrix,revealing the microstructure mechanism of the macroscopic mechanical properties.The thermal aging supervision samples from a nuclear power plant in China had been analyzed by small-angle neutron scattering.LI Bonan WANG Zijun LIU Rongdeng HAN Songbai SUN Kai CHEN Dongfeng LIU Yuntao WANG Chenglong TONG Zhenfeng LI Tianfu 2018中国原子能科学研究院年报2018,,1:0
