2Cold-chain transportation in the frozen food industry may have caused a recurrence of COVID-19 cases in destination:Successful isolation of SARS-CoV-2 virus from the imported frozen cod package surface显示文摘Coronavirus disease 2019(COVID-19)pandemic has spread in 220 countries/regions towreak havoc to human beings around theworld.At present,the second wave of COVID-19 has begun in many European countries.The complete control of COVID-19 is very urgent.Although China quickly brought the virus under control,there have been eight sporadic outbreaks in China since then.Both in Xinfadi of Beijing and Dalian outbreak of COVID-19,environmental swab samples related to imported cold chain food were tested nucleic acid positive for SARS-CoV-2.In this outbreak in Qingdao,we directly isolated SARS-CoV-2 from the cod outer package's surface swab samples.This is the first time worldwide,SARS-CoV-2 were isolated from the imported frozen cod outer package's surface,which showed that imported frozen food industry could import SARS-CoV-2 virus.Peipei Liu Mengjie Yang Xiang Zhao Yuanyuan Guo Liang Wang Jing Zhang Wenwen Lei Weifang Han Fachun Jiang William J.Liu George F.Gao Guizhen Wu 2020Biosafety and Health2020,2,4:41
3Ablation of gut microbiota alleviates obesity-induced hepatic steatosis and glucose intolerance by modulating bile acid metabolism in hamsters显示文摘Since metabolic process differs between humans and mice, studies were performed in hamsters, which are generally considered to be a more appropriate animal model for studies of obesityrelated metabolic disorders. The modulation of gut microbiota, bile acids and the farnesoid X receptor(FXR) axis is correlated with obesity-induced insulin resistance and hepatic steatosis in mice. However,the interactions among the gut microbiota, bile acids and FXR in metabolic disorders remained largely unexplored in hamsters. In the current study, hamsters fed a 60% high-fat diet(HFD) were administeredvehicle or an antibiotic cocktail by gavage twice a week for four weeks. Antibiotic treatment alleviated HFD-induced glucose intolerance, hepatic steatosis and inflammation accompanied with decreased hepatic lipogenesis and elevated thermogenesis in subcutaneous white adipose tissue(sWAT). In the livers of antibiotic-treated hamsters, cytochrome P450 family 7 subfamily B member 1(CYP7 B1) in the alternative bile acid synthesis pathway was upregulated, contributing to a more hydrophilic bile acid profile with increased tauro-β-muricholic acid(TβMCA). The intestinal FXR signaling was suppressed but remained unchanged in the liver. This study is of potential translational significance in determining the role of gut microbiota-mediated bile acid metabolism in modulating diet-induced glucose intolerance and hepatic steatosis in the hamster.Lulu Sun Yuanyuan Pang Xuemei Wang Qing Wu Huiying Liu Bo Liu George Liu Min Ye Wei Kong Changtao Jiang 2019Acta Pharmaceutica Sinica B2019,9,4:29
4Duck egg drop syndrome virus:an emerging Tembusu-related flavivirus in China显示文摘Duck egg drop syndrome virus(DEDSV) is a newly emerging pathogenic flavivirus isolated from ducks in China.DEDSV infection mainly results in severe egg drop syndrome in domestic poultry,which leads to huge economic losses.Thus,the discovery of ways and means to combat DEDSV is urgent.Since 2010,a remarkable amount of progress concerning DEDSV research has been achieved.Here,we review current knowledge on the epidemiology,symptomatology,and pathology of DEDSV.A detailed dissection of the viral genome and polyprotein sequences,comparative analysis of viral antigenicity and the corresponding potential immunity against the virus are also summarized.Current findings indicate that DEDSV should be a distinct species from Tembusu virus.Moreover,the adaption of DEDSV in wildlife and its high homology to pathogenic flaviviruses(e.g.,West Nile virus,Japanese encephalitis virus,and dengue virus),illustrate its reemergence and potential to become a zoonotic pathogen that should not be overlooked.Detailed insight into the antigenicity and corresponding immunity against the virus is of clear significance for the development of vaccines and antiviral drugs specific for DEDSV.LIU PeiPei LU Hao LI Shuang WU Ying George Fu GAO SU JingLiang 2013Science China(Life Sciences)2013,56,8:28
5Origin and molecular characterization of the human-infecting H6N1 infl uenza virus in Taiwan显示文摘In June 2013,the fi rst human H6N1 infl uenza virus infec-tion was confirmed in Taiwan.However,the origin and molecular characterization of this virus,A/Taiwan/2/2013(H6N1),have not been well studied thus far.In the present report,we performed phylogenetic and coalescent analy-ses of this virus and compared its molecular profi le/char-acteristics with other closely related strains.Molecular characterization of H6N1 revealed that it is a typical avian infl uenza virus of low pathogenicity,which might not rep-licate and propagate well in the upper airway in mammals.Phylogenetic analysis revealed that the virus clusters with A/chicken/Taiwan/A2837/2013(H6N1)in seven genes,except PB1.For the PB1 gene,A/Taiwan/2/2013 was clus-tered with a different H6N1 lineage from A/chicken/Taiwan/A2837/2013.Although a previous study demonstrated that the PB2,PA,and M genes of A/Taiwan/2/2013 might be derived from the H5N2 viruses,coalescent analyses revealed that these H5N2 viruses were derived from more recent strains than that of the ancestor of A/Taiwan/2/2013.Therefore,we propose that A/Taiwan/2/2013 is a reassor-tant from different H6N1 lineages circulating in chickens in Taiwan.Furthermore,compared to avian isolates,a sin-gle P186L(H3 numbering)substitution in the hemaggluti-nin H6 of the human isolate might increase the mammali-an receptor binding and,hence,this strain’s pathogenicity in humans.Overall,human infection with this virus seems an accidental event and is unlikely to cause an infl uenza pandemic.However,its co-circulation and potential reas-sortment with other infl uenza subtypes are still worthy of attention.Weifeng Shi Yi Shi Ying Wu Di Liu George F.Gao 2013Protein & Cell2013,4,11:26

8Combined acoustic radiation force impulse, aminotransferase to platelet ratio index and Forns index assessment for hepatic fibrosis grading in hepatitis B显示文摘AIM: To investigate the combined diagnostic accuracy of acoustic radiation force impulse(ARFI), aspartate aminotransferase to platelet ratio index(APRI) and Forns index for a non-invasive assessment of liver fibrosis in patients with chronic hepatitis B(CHB). METHODS: In this prospective study, 206 patients had CHB with liver fibrosis stages F0-F4 classified by METAVIR and 40 were healthy volunteers were measured by ARFI, APRI and Forns index separately or combined as indicated. RESULTS: ARFI, APRI or Forns index demonstrated a significant correlation with the histological stage(all P < 0.001). According to the AUROC of ARFI and APRI for evaluating fibrotic stages more than F2, ARFI showed an enhanced diagnostic accuracy than APRI(P < 0.05). The combined measurement of ARFI and APRI exhibited better accuracy than ARFI alone when evaluating ≥ F2 fibrotic stage(Z = 2.77, P = 0.006). Combination of ARFI, APRI and Forns index did not obviously improve the diagnostic accuracy compared to the combination of ARFI and APRI(Z = 0.958, P = 0.338). CONCLUSION: ARFI + APRI showed enhanced diagnostic accuracy than ARFI or APRI alone for significant liver fibrosis and ARFI + APRI + Forns index shows the same effect with ARFI + APRI.Chang-Feng Dong Jia Xiao Ling-Bo Shan Han-Ying Li Yong-Jia Xiong Gui-Lin Yang Jing Liu Si-Min Yao Sha-Xi Li Xiao-Hua Le Jing Yuan Bo-Ping Zhou George L Tipoe Ying-Xia Liu 2016World Journal of Hepatology2016,8,14:18

10Long Distance Transmission of SARS-CoV-2 from Contaminated Cold Chain Products to Humans——Qingdao City,Shandong Province,China,September 2020显示文摘Summary What is already known about this topic?Though coronavirus disease 2019(COVID-19)has largely been controlled in China,several outbreaks of COVID-19 have occurred from importation of cases or of suspected virus-contaminated products.Though several outbreaks have been traced to severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)isolated on the outer packaging of cold chain products,live virus has not been obtained.Huilai Ma Zhaoguo Wang Xiang Zhao Jun Han Yong Zhang Hong Wang Cao Chen Ji Wang Fachun Jiang Jie Lei Jingdong Song Shaofeng Jiang Shuangli Zhu Huihui Liu Dongyan Wang Yao Meng Naiying Mao Yanhai Wang Zhen Zhu Zhixiao Chen Bingling Wang Qinqin Song Haijun Du Qun Yuan Dong Xia Zhiqiang Xia Peipei Liu Yuchao Wu Zijian Feng Ruqin Gao George F.Gao Wenbo Xu 2021China CDC weekly2021,3,30:13
11Eleven COVID-19 Outbreaks with Local Transmissions Caused by the Imported SARS-CoV-2 Delta VOC-China,July-August,2021显示文摘Starting from December 2019,Wuhan,China,encountered the first outbreak of coronavirus disease 2019(COVID-19)(1-2).The epidemic was successfully suppressed by strict containment so that the number of infected people was reduced to 0 on April 8,2020(3–4).After that,China experienced roughly 3 dozen outbreaks with local transmission caused by imported severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).Lei Zhou Kai Nie Hongting Zhao Xiang Zhao Bixiong Ye Ji Wang Cao Chen Hong Wang Jiangli Di Jinsong Li Chao Li Zhixiao Chen Ruiqi Ren Peihua Niu Hui Chen Tao Chen Yali Wang Lili Li Bingxue Han Ruhan A Si Chen Dan Li Dan Li Chunxia Jin Xin Zhang Jiangmei Liu Chunyu Xu Yecheng Yao Yenan Feng Zhili Li Bike Zhang Yang Song Peter Hao Yanping Zhang Hao Li Qun Li George F.Gao Guoqing Shi Wenbo Xu 2021China CDC weekly2021,3,41:13

13Interaction of Hsp40 with influenza virus M2 protein: implications for PKR signaling pathway显示文摘Influenza virus contains three integral membrane proteins:haemagglutinin,neuraminidase,and matrix protein(M1 and M2).Among them,M2 protein functions as an ion channel,important for virus uncoating in endosomes of virus-infected cells and essential for virus replication.In an effort to explore potential new functions of M2 in the virus life cycle,we used yeast two-hybrid system to search for M2-associated cellular proteins.One of the positive clones was identified as human Hsp40/Hdj1,a DnaJ/Hsp40 family protein.Here,we report that both BM2(M2 of influenza B virus)and A/M2(M2 of influenza A virus)interacted with Hsp40 in vitro and in vivo.The region of M2-Hsp40 interaction has been mapped to the CTD1 domain of Hsp40.Hsp40 has been reported to be a regulator of PKR signaling pathway by interacting with p58^(IPK) that is a cellular inhibitor of PKR.PKR is a crucial component of the host defense response against virus infection.We therefore attempted to understand the relationship among M2,Hsp40 and p58^(IPK) by further experimentation.The results demonstrated that both A/M2 and BM2 are able to bind to p58^(IPK)in vitro and in vivo and enhance PKR autophosphorylation probably via forming a stable complex with Hsp40 and P58^(IPK),and consequently induce cell death.These results suggest that influenza virus M2 protein is involved in p58^(IPK)mediated PKR regulation during influenza virus infection,therefore affecting infected-cell life cycle and virus replication.Zhenhong Guan Di Liu Shuofu Mi Jie Zhang Qinong Ye Ming Wang George F.Gao Jinghua Yan 2010Protein & Cell2010,1,10:11
14A dimeric structure of PD-L1: functional units or evolutionary relics?显示文摘PD-L1 is a member of the B7 protein family,most of whose members so far were identified as dimers in a solution and crystalline state,either complexed or uncomplexed with their ligand(s).The binding of PD-L1 with its receptor PD-1(CD279)delivers an inhibitory signal regulating the T cell function.Simultaneously with the Garboczi group,we successfully solved another structure of human PD-L1(hPD-L1).Our protein crystallized in the space group of C222_(1) with two hPD-L1 molecules per asymmetric unit.After comparison of reported B7 structures,we have found some intrinsic factors involved in the interaction of these two molecules.Based on these results,we tend to believe this uncomplexed hPD-L1 structure demonstrated its potential dimeric state in solution,althougt it could just be an evolutionary relic,too weak to be detected under present technology,or still a functional unit deserved our attentions.Yong Chen Peipei Liu Feng Gao Hao Cheng Jianxun Qi George F.Gao 2010Protein & Cell2010,1,2:10
15Ent-11α-Hydroxy-15-oxo-kaur-16-en-19-oic-acid Inhibits Growth of Human Lung Cancer A549 Cells by Arresting Cell Cycle and Triggering Apoptosis显示文摘Objective: To examine the apoptotic effect of ent-11α-hydroxy-15-oxo-kaur-16-en-19-oic-acid (5F), a compound isolated from Pteris semipinnata L (PsL), in human lung cancer A549 cells. Methods: A549 cells were treated with 5F (0-80 μg/ml) for different time periods. Cytotoxicity was examined using a MTT method. Cell cycle was examined using propidium iodide staining. Apoptosis was examined using Hoechst 33258 staining, enzyme-linked immunosorbent assay (ELISA) and caspase-3 activity analysis. Expression of representative apoptosis-related proteins was evaluated by Western blot analysis. Reactive oxygen species (ROS) level was measured using standard protocols. Potential interaction of 5F with cisplatin was also examined. Results: 5F inhibited the proliferation of A549 cells in a concentration-and time-dependent manner. 5F increased the accumulation of cells in sub-G1 phase and arrested the cells in the G2 phase. Exposure to 5F induced morphological changes and DNA fragmentation that are characteristic of apoptosis. The expression of p21 was increased. 5F exposure also increased Bax expression, release of cytochrome c and apoptosis inducing factor (AIF), and activation of caspase-3. 5F significantly sensitized the cells to cisplatin toxicity. Interestingly, treatment with 5F did not increase ROS, but reduced ROS production induced by cisplatin. Conclusion: 5F could inhibit the proliferation of A549 cells by arresting the cells in G2 phase and by inducing mitochondrial-mediated apoptosis.Li Li George G Chen Ying-nian Lu Yi Liu Ke-feng Wu Xian-ling Gong Zhan-ping Gou Ming-yue Li Nian-ci Liang 2012Chinese Journal of Cancer Research2012,24,2:10
16Crystal structure of the swine-origin A (H1N1)- 2009 influenza A virus hemagglutinin (HA) reveals similar antigenicity to that of the 1918 pandemic virus显示文摘Influenza virus is the causative agent of the seasonal and occasional pandemic flu.The current H1N1 influenza pandemic,announced by the WHO in June 2009,is highly contagious and responsible for global economic losses and fatalities.Although the H1N1 gene segments have three origins in terms of host species,the virus has been named swine-origin influenza virus(S-OIV)due to a predominant swine origin.2009 S-OIV has been shown to highly resemble the 1918 pandemic virus in many aspects.Hemagglutinin is responsible for the host range and receptor binding of the virus and is therefore a primary indicator for the potential of infection.Primary sequence analysis of the 2009 S-OIV hemagglutinin(HA)reveals its closest relationship to that of the 1918 pandemic influenza virus,however,analysis at the structural level is necessary to critically assess the functional significance.In this report,we report the crystal structure of soluble hemagglutinin H1(09H1)at 2.9Å,illustrating that the 09H1 is very similar to the 1918 pandemic HA(18H1)in overall structure and the structural modules,including the five defined antiboby(Ab)-binding epitopes.Our results provide an explanation as to why sera from the survivors of the 1918 pandemics can neutralize the 2009 S-OIV,and people born around the 1918 are resistant to the current pandemic,yet younger generations are more susceptible to the 2009 pandemic.Wei Zhang Jianxun Qi Yi Shi Qing Li Feng Gao Yeping Sun Xishan Lu Qiong Lu Christopher J.Vavricka Di Liu Jinghua Yan George F.Gao 2010Protein & Cell2010,1,5:10
