| 1 | Isolation and characterization of H7N9 viruses from live poultry markets--Implication of the source of current H7N9 infection in humans显示文摘On March 31, 2013, the National Health and Family Planning Commission announced that human infections with a previously undescribed influenza A (H7N9) virus had occurred in Shanghai and Anhui Province, China. To investigate the possible origins of the H7N9 viruses causing these human infections, we collected 970 samples, including drinking water, soil, and cloacal and tracheal swabs of poultry from live poultry markets and poultry farms in Shanghai and Anhui Province. Twenty samples were positive for the H7N9 influenza virus. Notably, all 20 viruses were isolated from samples collected from live poultry markets in Shanghai. Phylogenetic analyses showed that the six internal genes of these novel human H7N9 viruses were derived from avian H9N2 viruses, but the ancestor of their HA and NA genes is uncertain. When we examined the phylogenetic relationship between the H7N9 isolates from live poultry markets and the viruses that caused the human infections, we found that they shared high homology across all eight gene segments. We thus identified the direct avian origin of the H7N9 influenza viruses that caused the human infections. Importantly, we observed that the H7N9 viruses isolated from humans had acquired critical mutations that made them more 'human-like'. It is therefore imperative to take strong measures to control the spread of H7N9 viruses in birds and humans to prevent further threats to human health. | SHI JianZhong DENG GuoHua LIU PeiHong ZHOU JinPing GUAN LiZheng LI WenHui LI XuYong GUO Jing WANG GuoJun FAN Jun WANG JinLiang LI YuanYuan JIANG YongPing LIU LiLing TIAN GuoBin LI ChengJun CHEN HuaLan | 2013 | Chinese Science Bulletin2013，58，16： | 85 |

| 3 | Functional exhaustion of antiviral lymphocytes in COVID-19 patients显示文摘In December 2019,a novel coronavirus was first reported in Wuhan,China.1 It was named by the World Health Organization as severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)and is responsible for coronavirus disease 2019(COVID-19).Up to 28 February 2020,79,394 cases have been confirmed according to China’s National Health Commission.Outside China,the virus has spread rapidly to over 36 countries and territories. | Yuanhong Xuand Zhigang Tian Meijuan Zheng Yong Gao Gang Wang Guobin Song Siyu Liu Dandan Sun Yuanhong Xu Zhigang Tian | 2020 | Cellular & Molecular Immunology2020，17，5： | 54 |
| 4 | Vaccination of poultry successfully eliminated human infection with H7N9 virus in China显示文摘The H7 N9 viruses that emerged in China in 2013 were nonpathogenic in chickens but mutated to a highly pathogenic form in early 2017 and caused severe disease outbreaks in chickens. The H7 N9 influenza viruses have caused five waves of human infection, with almost half of the total number of human cases(766 of 1,567) being reported in the fifth wave, raising concerns that even more human infections could occur in the sixth wave. In September 2017, an H5/H7 bivalent inactivated vaccine for chickens was introduced, and the H7 N9 virus isolation rate in poultry dropped by 93.3% after vaccination. More importantly,only three H7 N9 human cases were reported between October 1, 2017 and September 30, 2018, indicating that vaccination of poultry successfully eliminated human infection with H7 N9 virus. These facts emphasize that active control of animal disease is extremely important for zoonosis control and human health protection. | Xianying Zeng Guobin Tian Jianzhong Shi Guohua Deng Chengjun Li Hualan Chen | 2018 | Science China(Life Sciences)2018，61，12： | 37 |
| 5 | Genetic and biological characteristics of the globally circulating H5N8 avian influenza viruses and the protective efficacy offered by the poultry vaccine currently used in China显示文摘The H5N8 avian influenza viruses have been widely circulating in wild birds and are responsible for the loss of over 33 million domestic poultry in Europe, Russia, Middle East, and Asia since January 2020. To monitor the invasion and spread of the H5N8 virus in China, we performed active surveillance by analyzing 317 wild bird samples and swab samples collected from 41,172 poultry all over the country. We isolated 22 H5N8 viruses from wild birds and 14 H5N8 viruses from waterfowls. Genetic analysis indicated that the 36 viruses formed two different genotypes: one genotype viruses were widely detected from different wild birds and domestic waterfowls;the other genotype was isolated from a whopper swan. We further revealed the origin and spatiotemporal spread of these two distinct H5N8 virus genotypes in 2020 and 2021. Animal studies indicated that the H5N8 isolates are highly pathogenic to chickens, mildly pathogenic in ducks, but have distinct pathotypes in mice. Moreover, we found that vaccinated poultry in China could be completely protected against H5N8 virus challenge. Given that the H5N8 viruses are likely to continue to spread in wild birds, vaccination of poultry is highly recommended in high-risk countries to prevent H5N8 avian influenza. | Pengfei Cui Xianying Zeng Xuyong Li Yanbing Li Jianzhong Shi Conghui Zhao Zhiyuan Qu Yanwen Wang Jing Guo Wenli Gu Qi Ma Yuancheng Zhang Weipeng Lin Minghui Li Jingman Tian Dongxue Wang Xin Xing Yanjing Liu Shuxin Pan Yaping Zhang Hongmei Bao Liling Liu Guobin Tian Chengjun Li Guohua Deng Hualan Chen | 2022 | Science China(Life Sciences)2022，65，4： | 12 |
| 6 | Influenza A virus use of BinCARD1 to facilitate the binding of viral NP to importinα7 is counteracted by TBK1-p62 axis-mediated autophagy显示文摘As a major component of the viral ribonucleoprotein(vRNP)complex in influenza A virus(IAV),nucleoprotein(NP)interacts with isoforms of importinαfamily members,leading to the import of itself and vRNP complex into the nucleus,a process pivotal in the replication cycle of IAV.In this study,we found that BinCARD1,an isoform of Bcl10-interacting protein with CARD(BinCARD),was leveraged by IAV for efficient viral replication.BinCARD1 promoted the nuclear import of the vRNP complex and newly synthesized NP and thus enhanced vRNP complex activity.Moreover,we found that BinCARD1 interacted with NP to promote NP binding to importinα7,an adaptor in the host nuclear import pathway.However,we also found that BinCARD1 promoted RIG-I-mediated innate immune signaling by mediating Lys63-linked polyubiquitination of TRAF3,and that TBK1 appeared to degrade BinCARD1.We showed that BinCARD1 was polyubiquitinated at residue K103 through a Lys63 linkage,which was recognized by the TBK1-p62 axis for autophagic degradation.Overall,our data demonstrate that IAV leverages BinCARD1 as an important host factor that promotes viral replication,and two mechanisms in the host defense system are triggered—innate immune signaling and autophagic degradation—to mitigate the promoting effect of BinCARD1 on the life cycle of IAV. | Xuyuan Wang Li Jiang Guangwen Wang Wenjun Shi Yuzhen Hu Bo Wang Xianying Zeng Guobin Tian Guohua Deng Jianzhong Shi Liling Liu Chengjun Li Hualan Chen | 2022 | Cellular & Molecular Immunology2022，19，10： | 3 |
| 7 | H7N9 virus infection triggers lethal cytokine storm by activating gasdermin E-mediated pyroptosis of lung alveolar epithelial cells显示文摘The H7N9 influenza virus emerged in China in 2013,causing more than 1560 human infections,39% of which were fatal.A ‘cytokine storm’ in the lungs of H7N9 patients has been linked to a poor prognosis and death;however,the underlying mechanism that triggers the cytokine storm is unknown.Here,we found that efficient replication of the H7N9 virus in mouse lungs activates gasdermin E(GSDME)-mediated pyroptosis in alveolar epithelial cells,and that the released cytosolic contents then trigger a cytokine storm.Knockout of Gsdme switched the manner of death of A549 and human primary alveolar epithelial cells from pyroptosis to apoptosis upon H7N9 virus infection,and Gsdme knockout mice survived H7N9 virus lethal infection.Our findings reveal that GSDME activation is a key and unique mechanism for the pulmonary cytokine storm and lethal outcome of H7N9 virus infection and thus opens a new door for the development of antivirals against the H7N9 virus. | Xiaopeng Wan Jiqing Li Yupeng Wang Xiaofei Yu Xijun He Jianzhong Shi Guohua Deng Xianying Zeng Guobin Tian Yanbing Li Yongping Jiang Yuntao Guan Chengjun Li Feng Shao Hualan Chen | 2022 | National Science Review2022，9，1： | 3 |
| 8 | Nanomaterials for environmental burden reduction,waste treatment,and nonpoint source pollution control:a review显示文摘Nanomaterials are applicable in the areas of reduction of environmental burden,reduction/treatment of industrial and agricultural wastes,and nonpoint source(NPS)pollution control.First,environmental burden reduction involves green process and engineering,emissions control,desulfurization/denitrification of nonrenewable energy sources,and improvement of agriculture and food systems.Second,reduction/treatment of industrial and agricultural wastes involves converting wastes into products,groundwater remediation,adsorption,delaying photocatalysis,and nanomembranes.Third,NPS pollution control involves controlling water pollution.Nanomaterials alter physical properties on a nanoscale due to their high specific surface area to volume ratio.They are used as catalysts,adsorbents,membranes,and additives to increase activity and capability due to their high specific surface areas and nano-sized effects.Thus,nanomaterials are more effective at treating environmental wastes because they reduce the amount of material needed. | Guobin SHAN Rao Y.SURAMPALLI Rajeshwar D.TYAGI Tian C.ZHANG | 2009 | Frontiers of Environmental Science & Engineering2009，3，3： | 2 |

| 12 | Phase Characterization and Formation Behavior in 6 wt%Si High-silicon Austenitic Stainless Steel during Isothermal Aging显示文摘The precipitation behavior of different phases in a high-silicon stainless steel(6 wt%Si)during aging at 600–1050℃for24 h was investigated.The morphology,crystal structure and composition of various precipitates were detailly characterized using optical microscopy,scanning electron microscopy and transmission electron microscopy.Four phases were mainly identified:χ-phase,M_6C carbides,σphase and a new type of fcc-phase.During aging at 600–900℃,the main precipitate was(Cr,Mo and Si)-richχ-phase which was directly precipitated fromγmatrix.Theχ-phase was calibrated as bcc structure with a lattice parameter of 8.90?.The peak temperature for the precipitation ofχ-phase was 800℃,and it was dissolved when aging at temperatures above 1000℃.Theσ-phase was observed only at 700℃and grew next toχ-phase.Above 700℃,a new fcc-phase was found to be precipitated along withχ-phase,with a space group of Fd3c and a lattice parameter of 12.56?.The M_6C carbides started to be precipitated at 700℃in the vicinity ofχ-phase.And its amount basically increased with the increasing of temperature.An orientation relationship between M_6C/γwas found:[100]c//[100]γ,(001)c//(001)γ,i.e.,the cube-on-cube relationship. | Sihan Chen Tian Liang Yangtao Zhou Weiwei Xing Chengwu Zheng Yingche Ma JinMing Wu Guobin Li Kui Liu | 2021 | Acta Metallurgica Sinica(English Letters)2021，34，5： | 0 |
| 13 | Construction,identification and biological feature study of human hepatocellular carcinoma cells stably expressing HBeAg显示文摘Objective: To construct a HepG2 cell line which stably expressing Hepatitis B e antigen(HBeAg)and investigate the effects of HBeAg on the proliferation,migration and invasion of HepG2 cells. Methods: The lentivirus carrying HBeAg gene was constructed and packaged. HepG2 cells were infected with the lentivirus and screened with puromycin to obtain HepG2 cells which stably expressing HBeAg(HepG2-HBeAg cells).The expression levels of HBeAg mRNA and protein were detected by RT-qPCR and Western blot,respectively. The content of HBeAg secretion in cell supernatant in both HepG2-HBeAg cells and control cells(HepG2-NC cells and HepG2 cells)were detected by IFMA assay. Furthermore,CCK-8 proliferation assay,colony formation assay and transwell migration and invasion assays were conducted to compare the abilities of cell proliferation,migration and invasion,respectively. Results: The expression of HBeAg in the HepG2-HBeAg cell was significantly higher than those in HepG2 cells and HepG2-NC cells. Secreted HBeAg in the supernatant of HepG2-HBeAg cells was 26. 33±2. 13 PEIU/mL but was undetectable in supernatant of control cells. The proliferation,migration and invasion were all significantly lower in HepG2-HBeAg cells compared to control cells(P<0. 01). Conclusion: A HepG2 cell line which stably expressing HBeAg was constructed successfully,and the over-expression of HBeAg could attenuate the proliferation,migration and invasion of hepatocellular carcinoma cells. | Yuxuan Li Shan Huang Kezhi Li Guobin Wu Hao Tian Yinnong Zhao | 2017 | 广西医科大学学报2017，34，12： | 0 |
| 14 | Modeling of kilometer-scale ionospheric irregularities at Mars显示文摘Recently, kilometer-scale Martian ionospheric irregularities have been measured by the Mars Atmosphere and Volatile EvolutioN(MAVEN) mission(Fowler et al., 2020). In this study, we carried out a simulation of these irregularities, assuming a uniform Martian zonal neutral wind and a cosinusoidal perturbation of the plasma density as the seeding source. Results show that a vertical electric field shear could be induced by such a plasma density perturbation. We find that the vertical electric field shear causes a velocity shear of the plasma between the topside and bottomside ionosphere, which in turn is able to produce kilometer-scale ionospheric irregularities — irregularities of a smaller scale than were seen in previous simulations(Jiang CH et al., 2021). These kilometer-scale variations with altitude, in plasma density and magnetic field profiles, are comparable to the MAVEN observations. | ChunHua Jiang Rong Tian LeHui Wei GuoBin Yang ZhengYu Zhao | 2022 | Earth and Planetary Physics2022，6，2： | 0 |
| 15 | M6PR interacts with the HA2 subunit of influenza A virus to facilitate the fusion of viral and endosomal membranes显示文摘Influenza A virus(IAV) commandeers numerous host cellular factors for successful replication. However, very few host factors have been revealed to be involved in the fusion of viral envelope and late endosomal membranes. In this study, we identified cation-dependent mannose-6-phosphate receptor(M6PR) as a crucial host factor for the replication of IAV. We found that siRNA knockdown of M6PR expression significantly reduced the growth titers of different subtypes of IAV, and that the inhibitory effect of M6PR siRNA treatment on IAV growth was overcome by the complement of exogenously expressed M6PR. When A549 cells were treated with siRNA targeting M6PR,the nuclear accumulation of viral nucleoprotein(NP) was dramatically inhibited at early timepoints post-infection, indicating that M6PR engages in the early stage of the IAV replication cycle. By investigating the role of M6PR in the individual entry and post-entry steps of IAV replication, we found that the downregulation of M6PR expression had no effect on attachment, internalization, early endosome trafficking,or late endosome acidification. However, we found that M6PR expression was critical for the fusion of viral envelope and late endosomal membranes. Of note, M6PR interacted with the hemagglutinin(HA) protein of IAV, and further studies showed that the lumenal domain of M6PR and the ectodomain of HA2 mediated the interaction and directly promoted the fusion of the viral and late endosomal membranes,thereby facilitating IAV replication. Together, our findings highlight the importance of the M6PR–HA interaction in the fusion of viral and late endosomal membranes during IAV replication. | Yuzhen Hu Li Jiang Guangwen Wang Yangming Song Zhibo Shan Xuyuan Wang Guohua Deng Jianzhong Shi Guobin Tian Xianying Zeng Liling Liu Hualan Chen Chengjun Li | 2024 | Science China(Life Sciences)2024，67，3： | 0 |
