| 2 | The economic burden of influenza-associated outpatient visits and hospitalizations in China: a retrospective survey显示文摘Background:The seasonal influenza vaccine coverage rate in China is only 1.9%.There is no information available on the economic burden of influenza-associated outpatient visits and hospitalizations at the national level,even though this kind of information is important for informing national-level immunization policy decision-making.Methods:A retrospective telephone survey was conducted in 2013/14 to estimate the direct and indirect costs of seasonal influenza-associated outpatient visits and hospitalizations from a societal perspective.Study participants were laboratory-confirmed cases registered in the National Influenza-like Illness Surveillance Network and Severe Acute Respiratory Infections Sentinel Surveillance Network in China in 2013.Patient-reported costs from the survey were validated by a review of hospital accounts for a small sample of the inpatients.Results:The study enrolled 529 outpatients(median age:eight years;interquartile range[IQR]:five to 20 years)and 254 inpatients(median age:four years;IQR:two to seven years).Among the outpatients,22.1%(117/529)had underlying diseases and among the inpatients,52.8%(134/254)had underlying diseases.The average total costs related to influenza-associated outpatient visits and inpatient visits were US$155(standard deviation,SD US$122)and US$1,511(SD US$1,465),respectively.Direct medical costs accounted for 45 and 69%of the total costs related to influenza-associated outpatient and inpatient visits,respectively.For influenza outpatients,the mean cost per episode in children aged below five years(US$196)was higher than that in other age groups(US$129–153).For influenza inpatients,the mean cost per episode in adults aged over 60 years(US$2,735)was much higher than that in those aged below 60 years(US$1,417–1,621).Patients with underlying medical conditions had higher costs per episode than patients without underlying medical conditions(outpatients:US$186 vs.US$146;inpatients:US$1,800 vs.US$1,189).In the baseline analysis,inpatients reported costs were 18%higher than those found in the accounts review(n=38).Conclusion:The economic burden of influenza-associated outpatient and inpatient visits in China is substantial,particularly for young children,the elderly,and patients with underlying medical conditions.More widespread influenza vaccination would likely alleviate the economic burden of patients.The actual impact and cost-effectiveness analysis of the influenza immunization program in China merits further investigation. | Juan Yang Mark Jit Kathy S.Leung Ya-ming Zheng Lu-zhao Feng Li-ping Wang Eric H.Y.Lau Joseph T.Wu Hong-jie Yu | 2015 | Infectious Diseases of Poverty2015，4，1： | 44 |
| 3 | H5N1 avian influenza in China显示文摘H5N1 highly pathogenic avian influenza virus was first detected in a goose in Guangdong Province of China in 1996. Multiple genotypes of H5N1 viruses have been identified from apparently healthy waterfowl since 1999. In the years 2004-2008, over 100 outbreaks in domestic poultry occurred in 23 provinces and caused severe economic damage to the poultry industry in China. Beginning from 2004, a culling plus vaccination strategy has been implemented for the control of epidemics. Since then, over 35420000 poultry have been depopulated, and over 55 billion doses of the different vaccines have been used to control the outbreaks. Although it is logistically impossible to vaccinate every single bird in China due to the large poultry population and the complicated rearing styles, there is no doubt that the increased vaccination coverage has resulted in decreased disease epidemic and environmental virus loading. The experience in China suggests that vaccination has played an important role in the protection of poultry from H5N1 virus infection, the reduction of virus load in the environment, and the prevention of H5N1 virus transmission from poultry to humans. | CHEN HuaLan Animal Influenza Laboratory of the Ministry of Agriculture and National Key Laboratory of Veterinary Biotechnology, Harbin Veterinary Research Institute, Chinese Academy of Agricultural Sciences, Harbin 150001, China | 2009 | Science China(Life Sciences)2009，52，5： | 36 |
| 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 | Houttuynia cordata polysaccharide alleviated intestinal injury and modulated intestinal microbiota in H1N1 virus infected mice显示文摘Houttuynia cordata polysaccharide(HCP) is extracted from Houttuynia cordata, a key traditional Chinese medicine. The study was to investigate the effects of HCP on intestinal barrier and microbiota in H1N1 virus infected mice. Mice were infected with H1N1 virus and orally administrated HCP at a dosage of 40 mg×kg^(–1)×d^(–1). H1N1 infection caused pulmonary and intestinal injury and gut microbiota imbalance. HCP significantly suppressed the expression of hypoxia inducible factor-1α and decreased mucosubstances in goblet cells, but restored the level of zonula occludens-1 in intestine. HCP also reversed the composition change of intestinal microbiota caused by H1N1 infection, with significantly reduced relative abundances of Vibrio and Bacillus, the pathogenic bacterial genera. Furthermore, HCP rebalanced the gut microbiota and restored the intestinal homeostasis to some degree. The inhibition of inflammation was associated with the reduced level of Toll-like receptors and interleukin-1β in intestine, as well as the increased production of interleukin-10. Oral administration of HCP alleviated lung injury and intestinal dysfunction caused by H1N1 infection. HCP may gain systemic treatment by local acting on intestine and microbiota. This study proved the high-value application of HCP. | CHEN Mei-Yu LI Hong LU Xiao-Xiao LING Li-Jun WENG Hong-Bo SUN Wei CHEN Dao-Feng ZHANG Yun-Yi | 2019 | Chinese Journal of Natural Medicines2019，17，3： | 24 |
| 6 | Structure and sequence analysis of influenza A virus nucleoprotein显示文摘Influenza A virus nucleoprotein (NP) forms homo-oligomers and multiple copies of NP wrap around genomic RNA, along with a trimeric polymerase making up ribonucleoprotein (RNP) complex. Sequence comparison of more than 2500 influenza A NP showed that this protein contains 30.1 % of polymorphic residues. NP is composed of a head and a body domain and a tail loop/ linker region. The head domain is more conserved than the body domain, as revealed from the structure-based sequence alignment. NP oligomerization is mediated by the insertion of the non-polymorphic and structurally conserved tail loop of one NP molecule to a groove of another NP. The different form of NP oligomers is due to the flexibility of the polymorphic linkers that join the tail loop to the rest of the protein. The RNA binding property of NP is known to involve the protruding element and the flexible basic loop between the head and body domains, both having high degree of primary sequence conservation. To bind RNA, NP may first capture the RNA by the flexible basic loop and then the RNA is clamped by the protruding element. | NG Andy Ka-Leung SHAW Pang-Chui | 2009 | Science China(Life Sciences)2009，52，5： | 18 |

| 8 | Interspecies transmission and host restriction of avian H5N1 influenza virus显示文摘Long-term endemicity of avian H5N1 influenza virus in poultry and continuous sporadic human infections in several countries has raised the concern of another potential pandemic influenza. Suspicion of the avian origin of the previous pandemics results in the close investigation of the mechanism of interspecies transmission. Entry and fusion is the first step for the H5N1 influenza virus to get into the host cells affecting the host ranges. Therefore receptor usage study has been a major focus for the last few years. We now know the difference of the sialic acid structures and distributions in different species, even in the different parts of the same host. Many host factors interacting with the influenza virus component proteins have been identified and their role in the host range expansion and interspecies transmission is under detailed scrutiny. Here we review current progress in the receptor usage and host factors. | GAO George Fu | 2009 | Science China(Life Sciences)2009，52，5： | 14 |
| 9 | H5N6 influenza virus infection, the newest influenza显示文摘The most recent new emerging infection is the H5N6 inl uenza virus infection. This infection has just been reported from China in early May 2014. The disease is believed to be a cross species infection. All indexed cases are from China. Of interest, the H5N6 inl uenza virus is the primary virus for avian. The avian H5N6 inl uenza virus in avian population is a low virulent strain. However, the clinical manifestation in human seems severe. In this mini-review, the authors summarize and discuss on this new emerging inl uenza. | Beuy Joob Wiwanitkit Viroj | 2015 | Asian Pacific Journal of Tropical Biomedicine2015，5，6： | 14 |
| 10 | Research progress on human infection with avian influenza H7N9显示文摘Since the first case of novel H7N9 infection was reported,China has experienced five epidemics of H7N9.During the fifth wave,a highly pathogenic H7N9 strain emerged.Meanwhile,the H7N9 virus continues to accumulate mutations,and its affinity for the human respiratory epithelial sialic acid 2-6 receptor has increased.Therefore,a pandemic is still possible.In the past 6 years,we have accumulated rich experience in dealing with H7N9,especially in terms of virus tracing,epidemiological research,key site mutation monitoring,critical disease mechanisms,clinical treatment,and vaccine development.In the research fields above,significant progress has been made to effectively control the spread of the epidemic and reduce the fatality rate.To fully document the research progress concerning H7N9,we reviewed the clinical and epidemiological characteristics of H7N9,the key gene mutations of the virus,and H7N9 vaccine,thus providing a scientific basis for further monitoring and prevention of H7N9 influenza epidemics. | Xiaoxin Wu Lanlan Xiao Lanjuan Li | 2020 | Frontiers of Medicine2020，14，1： | 14 |
| 11 | Human avian influenza A (H5N1) virus infection in China显示文摘Highly pathogenic influenza A (H5N1) virus causes a widespread poultry deaths worldwide. The first human H5N1 infected case was reported in Hong Kong Special Administrative Region of China in 1997. Since then, the virus re-emerged in 2003 and continues to infect people worldwide. Currently, over 400 human infections have been reported in more than 15 countries and mortality rate is greater than 60%. H5N1 viruses still pose a potential pandemic threat in the future because of the continuing global spread and evolution. Here, we summarize the epidemiological, clinical and virological characteristics of human H5N1 infection in China monitored and identified by our national surveillance systems. | XU CuiLin, DONG LiBo, XIN Li, LAN Yu, CHEN YongKun, YANG LiMei & SHU YueLong State Key Laboratory for Viral Genetic and Engineering, National Institute for Viral Disease Control and Prevention, Chinese Center for Disease Control and Prevention (China CDC), Beijing 100052, China | 2009 | Science China(Life Sciences)2009，52，5： | 14 |

| 13 | Influenza A virus H5N1 entry into host cells is through clathrin-dependent endocytosis显示文摘Influenza A virus H5N1 presents a major threat to human health. The entry of influenza virus into host cells is believed to be mediated by hemagglutinin (HA), a virus surface glycoprotein that can bind terminal sialic acid residues on host cell glycoproteins and glycolipids. In this study, we elucidated the pathways through which H5N1 enters human lung carcinoma cell line A549. We first proved that H5N1 can enter A549 cells via endocytosis, as lysosomotropic agents, such as bafilomycin A1 and chloroquine, can rescue H5N1-induced A549 cell death. By using specific inhibitors, and siRNAs that target the clathrin pathway, we further found that H5N1 could enter A549 cells via clathrin-mediated endocytosis, while inhibitors targeting caveolae-mediated endocytosis could not inhibit H5N1 cell entry. These findings expand our understanding of H5N1 pathogenesis and provide new information for anti-viral drug research. | WANG HongLiang & JIANG ChengYu National Key Laboratory of Medical Molecular Biology, Institute of Basic Medical Sciences, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing 100005, China | 2009 | Science China(Life Sciences)2009，52，5： | 11 |
| 14 | Na^+/K^+-ATPase β1 subunit interacts with M2 proteins of influenza A and B viruses and affects the virus replication显示文摘Interplay between the host and influenza virus has a pivotal role for the outcome of infection.The matrix proteins M2/BM2 from influenza (A and B) viruses are small type III integral membrane proteins with a single transmembrane domain,a short amino-terminal ectodomain and a long carboxy-terminal cytoplasmic domain.They function as proton channels,mainly forming a membrane-spanning pore through the transmembrane domain tetramer,and are essential for virus assembly and release of the viral genetic materials in the endosomal fusion process.However,little is known about the host factors which interact with M2/BM2 proteins and the functions of the long cytoplasmic domain are currently unknown.Starting with yeast two-hybrid screening and applying a series of experiments we identified that the β1 subunit of the host Na+/K+-ATPase β1 subunit (ATP1B1) interacts with the cytoplasmic domain of both the M2 and BM2 proteins.A stable ATP1B1 knockdown MDCK cell line was established and we showed that the ATP1B1 knockdown suppressed influenza virus A/WSN/33 replication,implying that the interaction is crucial for influenza virus replication in the host cell.We propose that influenza virus M2/BM2 cytoplasmic domain has an important role in the virus-host interplay and facilitates virus replication. | GAO George Fu | 2010 | Science China(Life Sciences)2010，53，9： | 10 |

| 16 | Erucic acid from Isatis indigotica Fort. suppresses influenza A virus replication and inflammation in vitro and in vivo through modulation of NF-kB and p38 MAPK pathway显示文摘Isatis indigotica Fort.(Ban-Lan-Gen)is an herbal medicine prescribed for influenza treatment.However,its active components and mode of action remain mostly unknown.In the present study,erucic acid was isolated from Isatis indigotica Fort.,and subsequently its underlying mechanism against influenza A virus(IAV)infection was investigated in vitro and in vivo.Our results demonstrated that erucic acid exhibited broad-spectrum antiviral activity against IAV resulting from reduction of viral polymerase transcription activity.Erucic acid was found to exert inhibitory effects on IAV or viral(v)RNA-induced pro-inflam-matory mediators as well as interferons(IFNs).The molecular mechanism by which erucic acid with antiviral and anti-inflammatory properties was attributed to inactivation of NF-kB and p38 MAPK signaling.Furthermore,the NF-kB and p38 MAPK inhibitory effect of erucic acid led to diminishing the transcriptional activity of interferon-stimulated gene factor 3(ISGF-3),and thereby reducing IAV-triggered pro-inflammatory response amplification in IFN-β-sensitized cells.Additionally,IAV-or vRNA-triggered apoptosis of alveolar epithelial A549 cells was prevented by erucic acid.In vivo,erucic acid administration consistently displayed decreased lung viral load and viral antigens expression.Meanwhile,erucic acid markedly reduced CD8+cytotoxic T lymphocyte(CTL)recruitment,pro-apoptotic signaling,hyperactivity of multiple signaling pathways,and exacerbated immune inflammation in the lung,which resulted in decreased lung injury and mortality in mice with a mouse-adapted A/FM/1/47-MA(H1N1)strain infection.Our findings provided a mechanistic basis for the action of erucic acid against IAV-mediated inflammation and injury,suggesting that erucic acid may have a therapeutic potential in the treatment of influenza. | Xiaoli Liang Yuan Huang Xiping Pan Yanbing Hao Xiaowei Chen Haiming Jiang Jing Li Beixian Zhou Zifeng Yang | 2020 | Journal of Pharmaceutical Analysis2020，10，2： | 10 |

| 19 | Ventilator management for acute respiratory distress syndrome associated with avian infl uenza A(H7N9) virus infection: A case series显示文摘BACKGROUND: Data on the mechanical ventilation(MV) characteristics and radiologic features for the cases with H7 N9-induced ARDS were still lacking.METHODS: We describe the MV characteristics and radiologic features of adult patients with ARDS due to microbiologically confirmed H7 N9 admitted to our ICU over a 3-month period.RESULTS: Eight patients(mean age 57.38±16.75; 5 male) were diagnosed with H7 N9 in the first quarter of 2014. All developed respiratory failure complicated by acute respiratory distress syndrome(ARDS), which required MV in ICU. The baseline APACHE II and SOFA score was 11.77±6.32 and 7.71±3.12. The overall CT scores of the patients was 247.68±34.28 and the range of CT scores was 196.3–294.7. The average MV days was 14.63±6.14, and 4 patients required additional rescue therapies for refractory hypoxemia. Despite these measures, 3 patients died.CONCLUSION: In H7 N9-infected patients with ARDS, low tidal volume strategy was the conventional mode. RM as one of rescue therapies to refractory hypoxemia in these patients with serious architectural distortion and high CT scores, which could cause further lung damage, may induce bad outcomes and requires serious consideration. Prone ventilation may improve mortality, and should be performed at the early stage of the disease, not as a rescue therapy. | Hui Xie Zhi-gang Zhou Wei Jin Cheng-bin Yuan Jiang Du Jian Lu Rui-lan Wang | 2018 | World Journal of Emergency Medicine2018，9，2： | 9 |
| 20 | Effect of the Haoqinqingdan decoction on damp-heat syndrome in rats with influenza viral pneumonia显示文摘Objective: To investigate the effect of Chinese medicine prescription-Haoqinqingdan decoction on damp-heat syndrome in rats with influenza viral pneumonia and its influence on the immune function. Methods: A total of 48 Wistar rats were randomly divided into the normal control group, the damp-heat syndrome model group, the Haoqinqingdan decoction group (high, medium and low dose group) and the ribavirin group. The body temperature and weight of rats in each group were recorded after modeling. After treatment for 6 d, the concentration of T lymphocyte subgroup (CD3+ CD4+ , CD3+ CD8+ ) was determined by flow cytometry. The OD value of IFN毭/IL-4 was detected by double-antibody sandwich ELISA method, and its concentration was acquired through conversion. Results: After modeling, the temperature and weight of rats in each modeling group showed the increasing trend ( P<0.01). From the second day of treatment, there was significant difference in the body mass between groups, and the rat weight of the control group was higher than in the modeling group ( P<0.05 or 0.01). With the advances of treatment, only the temperature in the medium and high dose Haoqinqingdan decoction groups declined significantly ( P<0.05). After treatment, the CD4+ /CD8+ ratio of the damp-heat syndrome model group decreased more significantly compared with the control group. Elevated CD3+ CD8+ percentages and declined CD4+ /CD8+ ratios can be observed in the low dose group and ribavirin group ( P<0.05). Moreover, the CD3+ CD4+ percentage of ribavirin group was lower than in the control group ( P<0.05). After treatment, the IFN-毭 and IFN-毭/ IL-4 levels in the peripheral blood of rats in the dampheat syndrome group were obviously higher than in the control group ( P<0.05). Conclusions: Compared with ribavirin, the high dose Haoqinqingdan decoction can improve the ratio of T lymphocyte subgroup and Th1/Th2 cell balance more effectively. | Shi-Jin Zhang Zhuo Chen Guo-Wen Li Bo-Liang Wang | 2013 | Asian Pacific Journal of Tropical Medicine2013，6，8： | 8 |
