| 1 | High expression of ACE2 receptor of 2019-nCoV on the epithelial cells of oral mucosa显示文摘It has been reported that ACE2 is the main host cell receptor of 2019-nCoV and plays a crucial role in the entry of virus into the cell to cause the final infection. To investigate the potential route of 2019-n Cov infection on the mucosa of oral cavity, bulk RNA-seq profiles from two public databases including The Cancer Genome Atlas(TCGA) and Functional Annotation of The Mammalian Genome Cap Analysis of Gene Expression(FANTOM5 CAGE) dataset were collected. RNA-seq profiling data of 13 organ types with para-carcinoma normal tissues from TCGA and 14 organ types with normal tissues from FANTOM5 CAGE were analyzed in order to explore and validate the expression of ACE2 on the mucosa of oral cavity. Further, single-cell transcriptomes from an independent data generated in-house were used to identify and confirm the ACE2-expressing cell composition and proportion in oral cavity. The results demonstrated that the ACE2 expressed on the mucosa of oral cavity. Interestingly, this receptor was highly enriched in epithelial cells of tongue. Preliminarily, those findings have explained the basic mechanism that the oral cavity is a potentially high risk for 2019-nCoV infectious susceptibility and provided a piece of evidence for the future prevention strategy in dental clinical practice as well as daily life. | Hao Xu Liang Zhong Jiaxin Deng Jiakuan Peng Hongxia Dan Xin Zeng Taiwen Li Qianming Chen | 2020 | International Journal of Oral Science2020,12,1: | 69 |

| 3 | Review of risk factors for human echinococcosis prevalence on the Qinghai-Tibet Plateau, China: a prospective for control options显示文摘Objective: Echinococcosis is a major parasitic zoonosis of public health importance in western China. In 2004, the Chinese Ministry of Health estimated that 380,000 people had the disease in the region. The Qinghai-Tibet Plateau is highly co-endemic with both alveolar echinococcosis (AE) and cystic echinococcosis (CE). In the past years, the Chinese government has been increasing the financial support to control the diseases in this region. Therefore, it is very important to identify the significant risk factors of the diseases by reviewing studies done in the region in the past decade to help policymakers design appropriate control strategies. Review: Selection criteria for which literature to review were firstly defined. Medline, CNKI (China National Knowledge Infrastructure), and Google Scholar were systematically searched for literature published between January 2000 and July 2011. Significant risk factors found by single factor and/or multiple factors analysis were listed, counted, and summarized. Literature was examined to check the comparability of the data;age and sex specific prevalence with same data structures were merged and used for further analysis. A variety of assumed social, economical, behavioral, and ecological risk factors were studied on the Plateau. Those most at risk were Tibetan herdsmen, the old and female in particular. By analyzing merged comparable data, it was found that females had a significant higher prevalence, and a positive linearity relationship existed between echinococcosis prevalence and increasing age. In terms of behavioral risk factors, playing with dogs was mostly correlated with CE and/or AE prevalence. In terms of hygiene, employing ground water as the drinking water source was significantly correlated with CE and AE prevalence. For definitive hosts, dog related factors were most frequently identified with prevalence of CE or/and AE;fox was a potential risk factor for AE prevalence only. Overgrazing and deforestation were significant for AE prevalence only. Conclusion: Tibetan herdsmen communities were at the highest risk of echinococcosis prevalence and should be the focus of echinococcosis control. Deworming both owned and stray dogs should be a major measure for controlling echinococcosis;treatment of wild definitive hosts should also be considered for AE endemic areas. Health education activities should be in concert with the local people's education backgrounds and languages in order to be able to improve behaviors. Further researches are needed to clarify the importance of wild hosts for AE/CE prevalence, the extent and range of the impacts of ecologic changes (overgrazing and deforestation) on the AE prevalence, and risk factors in Tibet. | Qian Wang Yan Huang Liang Huang Wenjie Yu Wei He Bo Zhong Wei Li Xiangman Zeng Dominique A Vuitton Patrick Giraudoux Philip S Craig Weiping Wu | 2014 | Infectious Diseases of Poverty2014,3,1: | 35 |
| 4 | Does Helicobacter pylori infection play a role in iron deficiency anemia? A meta-analysis显示文摘AIM:To perform a meta-analysis of observational studies and randomized controlled trials(RCTs)on the association between Helicobacter pylori(H.pylori)and iron deficiency anemia(IDA).METHODS:A defined search strategy was used to search Medline,Embase,the Cochrane Library,Clinical Trials,Cochrane Central Register of Controlled Trials,Premedline and Healthstar.Odds ratio(OR)was used to evaluate observational epidemiology studies,and weighted mean difference(WMD)was used to demonstrate the difference between control and intervention groups.RESULTS:Fifteen observational studies and 5 RCTs were identified and used for calculation.The pooled OR for observational studies was 2.22(95%CI:1.52-3.24,P<0.0001).The WMD for hemoglobin(HB) was 4.06 g/L(95%CI:-2.57-10.69,P=0.01),and the WMD for serum ferritin(SF)was 9.47μg/L(95%CI:-0.50-19.43,P<0.0001).Results were heterogeneous for all comparisons.CONCLUSION:This meta-analysis on observational studies suggests an association between H.pylori and IDA.In RCTs,eradication of H.pylori can improve HB and SF levels but not significantly. | Qu, Xin-Hua Huang, Xiao-Lu Xiong, Ping Zhu, Cui-Ying Huang, You-Liang Lu, Lun-Gen Sun, Xu Rong, Lan Zhong, Liang Sun, Da-Yu Lin, Hai Cai, Ming-Ci Chen, Zhi-Wei Hu, Bing Wu, Lian-Ming Jiang, Yi-Bin Yan, Wei-Li | 2010 | World Journal of Gastroenterology2010,16,7: | 34 |
| 5 | A Simple and Rapid Colloidal Gold-based Immunochromatogarpic Strip Test for Detection of FMDV Serotype A显示文摘A sandwich format immunochromatographic assay for detecting foot-and-mouth disease virus (FMDV) serotypes was developed. In this rapid test,affinity purified polyclonal antibodies from Guinea pigs which were immunized with sucking-mouse adapted FMD virus (A/AV88(L) strain) were conjugated to colloidal gold beads and used as the capture antibody,and affinity purified polyclonal antibodies from rabbits which were immunized with cell-culture adapted FMD virus (A/CHA/09 strain) were used as detector antibody. On the nitrocellulose membrane of the immunochromatographic strip,the capture antibody was laid on a sample pad,the detector antibody was printed at the test line(T) and goat anti-guinea pigs IgG antibodies were immobilized to the control line(C). The lower detection limit of the test for a FMDV 146S antigen is 11.7ng/ml as determined in serial tests after the strip device was assembled and the assay condition optimization. No cross reactions were found with FMDV serotype C,Swine vesicular disease (SVD),Vesicular stomatiti svirus (VSV) and vesicular exanthema of swine virus (VES) viral antigens with this rapid test. Clinically,the diagnostic sensitivity of this test for FMDV serotypes A was 88.7% which is as same as an indirect-sandwich ELISA. The specificity of this strip test was 98.2% and is comparable to the 98.7% obtained with indirect-sandwich ELISA. This rapid strip test is simple,easy and fast for clinical testing on field sites; no special instruments and skills are required,and the result can be obtained within 15 min. To our knowledge,this is the first rapid immunochromatogarpic assay for serotype A of FMDV. | Tao Jiang Zhong Liang Wei-wei Ren Juan Chen Xiao-ying Zhi Guang-yu Qi Xiang-tao Liu Xue-peng Cai | 2011 | Virologica Sinica2011,26,1: | 22 |
| 6 | Resuscitation therapy for traumatic brain injuryinduced coma in rats:mechanisms of median nerve electrical stimulation显示文摘In this study, rats were put into traumatic brain injury-induced coma and treated with median nerve electrical stimulation. We explored the wake-promoting effect, and possible mechanisms, of median nerve electrical stimulation. Electrical stimulation upregulated the expression levels of orexin-A and its receptor OX1 R in the rat prefrontal cortex. Orexin-A expression gradually increased with increasing stimulation, while OX1 R expression reached a peak at 12 hours and then decreased. In addition, after the OX1 R antagonist, SB334867, was injected into the brain of rats after traumatic brain injury, fewer rats were restored to consciousness, and orexin-A and OXIR expression in the prefrontal cortex was downregulated. Our findings indicate that median nerve electrical stimulation induced an up-regulation of orexin-A and OX1 R expression in the prefrontal cortex of traumatic brain injury-induced coma rats, which may be a potential mechanism involved in the wake-promoting effects of median nerve electrical stimulation. | Zhen Feng Ying-jun Zhong Liang Wang Tian-qi Wei | 2015 | Neural Regeneration Research2015,10,4: | 23 |
| 7 | Special Section:SARS-CoV-2 Preliminary evidence from a multicenter prospective observational study of the safety and efficacy of chloroquine for the treatment of COVID-19显示文摘Effective therapies are urgently needed for the SARS-CoV-2 pandemic.Chloroquine has been proved to have antiviral effect against coronavirus in vitro.In this study,we aimed to assess the efficacy and safety of chloroquine with different doses in COVID-19.In this multicenter prospective observational study,we enrolled patients older than 18 years old with confirmed SARS-CoV-2 infection excluding critical cases from 12 hospitals in Guangdong and Hubei Provinces.Eligible patients received chloroquinephosphate s00 mg,orally,once(half dose)or twice(full dose)daily.Patients treated with non-chloroquine therapy were included as historical controls.The primary endpoint is the time to undetectable viral RNA.Secondary outcomes include the proportion of patients with undetectable viral RNA by day 10 and 14,hospitalization time,duration of fever,and adverse events.A total of 197 patients completed chloroquine treatment,and 176patients were included as historical controls.The median time to achieve an undetectable viral RNA was shorter in chloroquine than in non-chloroquine(absolute difference in medians-6.0 days;95%CI-6.0 to—4.0).The duration of fever is shorter in chloroquine(geometric mean ratio 0.6;95%CIO.5 to 0.8).No serious adverse events were observed in the chloroquine group.Patients treated with half dose experienced lower rate of adverse events than with full dose.Although randomized trials are needed for further evaluation,this study provides evidence for safety and efficacy of chloroquine in COVID-19 and suggests that chloroquine can be a cost-effective therapy for combating the COVID-19 pandemic. | Mingxing Huang Man Li Fei Xiao Pengfei Pang Jiabi Liang Tiantian Tang Shaoxuan Liu Binghui Chen Jingxian Shu Yingying You Yang Li Meiwen Tang Jianhui Zhou Guanmin Jiang Jingfen Xiang Wenxin Hong Songmei He Zhaoqin Wang Jianhua Feng Changqing Lin Yinong Ye Zhilong Wu Yaocai Li Bei Zhong Ruilin Sun Zhongsi Hong Jing Liu Huili Chen Xiaohua Wang Zhonghe Li Duanqing Pei Lin Tian Jinyu Xia Shanping Jiang Nanshan Zhong Hong Shan | 2020 | National Science Review2020,7,9: | 20 |
| 8 | β-sitosterol ameliorates influenza A virus-induced proinflammatory response and acute lung injury in mice by disrupting the cross-talk between RIG-I and IFN/STAT signaling显示文摘β-Sitosterol(24-ethyl-5-cholestene-3-ol)is a common phytosterol Chinese medical plants that has been shown to possess antioxidant and anti-inflammatory activity.In this study we investigated the effects ofβ-sitosterol on influenza virus-induced inflammation and acute lung injury and the molecular mechanisms.We demonstrate thatβ-sitosterol(150–450μg/mL)dosedependently suppresses inflammatory response through NF-κB and p38 mitogen-activated protein kinase(MAPK)signaling in influenza A virus(IAV)-infected cells,which was accompanied by decreased induction of interferons(IFNs)(including Type I and III IFN).Furthermore,we revealed that the anti-inflammatory effect ofβ-sitosterol resulted from its inhibitory effect on retinoic acidinducible gene I(RIG-I)signaling,led to decreased STAT1 signaling,thus affecting the transcriptional activity of ISGF3(interferonstimulated gene factor 3)complexes and resulting in abrogation of the IAV-induced proinflammatory amplification effect in IFNsensitized cells.Moreover,β-sitosterol treatment attenuated RIG-I-mediated apoptotic injury of alveolar epithelial cells(AEC)via downregulation of pro-apoptotic factors.In a mouse model of influenza,pre-administration ofβ-sitosterol(50,200 mg·kg−1·d−1,i.g.,for 2 days)dose-dependently ameliorated IAV-mediated recruitment of pathogenic cytotoxic T cells and immune dysregulation.In addition,pre-administration ofβ-sitosterol protected mice from lethal IAV infection.Our data suggest thatβ-sitosterol blocks the immune response mediated by RIG-I signaling and deleterious IFN production,providing a potential benefit for the treatment of influenza. | Bei-xian Zhou Jing Li Xiao-li Liang Xi-ping Pan Yan-bing Hao Pei-fang Xie Hai-ming Jiang Zi-feng Yang Nan-shan Zhong | 2020 | Acta Pharmacologica Sinica2020,41,9: | 20 |
| 9 | Preliminary results of environmental monitoring of the natural gas hydrate production test in the South China Sea显示文摘Natural gas hydrate (NGH)is considered as one of the new clean energy sources of the 21st century with the highest potential.The environmental issues of NGH production have attracted the close attention of scientists in various countries.From May 10 to July 9,2017,the first offshore NGH production test in the South China Sea (SCS)was conducted by the China Geological Survey.In addition,environmental security has also been effectively guaranteed via a comprehensive environmental monitoring system built during the NGH production test.The monitoring system considered sea-surface atmosphere methane and carbon dioxide concentrations,dissolved methane in the sea water column,and the seafloor physical oceanography and marine chemistry environment.The whole process was monitored via multiple means, in multiple layers,in all domains,and in real time.After the production test,an environmental investigation was promptly conducted to evaluate the environmental impact of the NGH production test. The monitoring results showed that the dissolved methane concentration in seawater and the near-seabed environment characteristics after the test were consistent with the background values,indicating that the NGH production test did not cause environmental problems such as methane leakage. | Jian-liang Ye Xu-wen Qin Hai-jun Qiu Qian-yong Liang Yi-fei Dong Jian-gong Wei Hai-long Lu Jing-an Lu Yao-hong Shi Chao Zhong Zhen Xia | 2018 | China Geology2018,1,2: | 19 |

| 12 | SHP2 inhibition triggers anti-tumor immunity and synergizes with PD-1 blockade显示文摘Tyrosine phosphatase SHP2 is a promising drug target in cancer immunotherapy due to its bidirectional role in both tumor growth promotion and T-cell inactivation. Its allosteric inhibitor SHP099 is known to inhibit cancer cell growth both in vitro and in vivo. However, whether SHP099-mediated SHP2 inhibition retards tumor growth in vivo via anti-tumor immunity remains elusive. To address this, a CT-26 colon cancer xenograft model was established in mice since this cell line is insensitive to SHP099.Consequently, SHP099 minimally affected CT-26 tumor growth in immuno-deficient nude mice, but significantly decreased the tumor burden in CT-26 tumor-bearing mice with intact immune system.SHP099 augmented anti-tumor immunity, as shown by the elevated proportion of CD8tIFN-γtT cells and the upregulation of cytotoxic T-cell related genes including Granzyme B andPerforin, which decreased the tumor load. In addition, tumor growth in mice with SHP2-deficient T-cells was markedly slowed down because of enhanced anti-tumor responses. Finally, the combination of SHP099 and antiPD-1 antibody showed a higher therapeutic efficacy than either monotherapy in controlling tumor growthin two colon cancer xenograft models, indicating that these agents complement each other. Our study suggests that SHP2 inhibitor SHP099 is a promising candidate drug for cancer immunotherapy. | Mingxia Zhao Wenjie Guo Yuanyuan Wu Chenxi Yang Liang Zhong Guoliang Deng Yuyu Zhu Wen Liu Yanhong Gu Yin Lu Lingdong Kong Xiangbao Meng Qiang Xu Yang Sun | 2019 | Acta Pharmaceutica Sinica B2019,9,2: | 18 |

| 15 | Effectiveness of Different Waist Circumference Cut-off Values in Predicting Metabolic Syndrome Prevalence and Risk Factors in Adults in China显示文摘Objective To study the effectiveness of waist circumference cut-off values in predicting the prevalence of metabolic syndrome(MetS) and risk factors in adults in China. Methods A cross-sectional survey was condcuted in 14 provinces(autonomous region, municipality) in China. A total of 47 325 adults aged ≥20 years were selected by multistage stratified sampling, and questionnaire survey and physical and clinical examination were conducted among them. MetS was defined according to the International Diabetes Federation(IDF) criteria and modified IDF criteria.Results The age-standardized prevalence of MetS was 24.2%(22.1% in men and 25.8% in women) and 19.5%(22.1% in men and 18.0% in women) according to the IDF criteria and modified IDF criteria respectively. The age-standardized prevalence of pre-MetS was 8.1%(8.6% in men and 7.8% in women) according to the modified IDF criteria. The prevalence of MetS was higher in urban residents than rural residents and in northern China residents than in southern China residents. The prevalence of central obesity was about 30% in both men and women according to the ethnicity-specific cut-off values of waist circumference for central obesity(90 cm for men and 85 cm for women). Multivariate regression analysis revealed no significant difference in risk factors between the two MetS definitions. Conclusion Using both the modified IDF criteria and ethnicity-specific cut-off values of waist circumference can provide more useful information about the prevalence of MetS in China. | ZHOU Hai Cheng LAI Ya Xin SHAN Zhong Yan JIA Wei Ping YANG Wen Ying LU Ju Ming WENG Jian Ping JI Li Nong LIU Jie TIAN Hao Ming JI Qiu He ZHU Da Long CHEN Li GUO Xiao Hui ZHAO Zhi Gang Li Qiang ZHOU Zhi Guang GE Jia Pu SHAN Guang Liang | 2014 | Biomedical and Environmental Sciences2014,27,5: | 17 |
| 16 | Bone marrow-derived dendritic cells pulsed with tumor lysates induce anti-tumor immunity against gastric cancer ex vivo显示文摘AIM:To investigate whether bone marrow-derived denritic cells pulsed with tumor lysates induce immunity against gastric cancer ex vivo. METHODS:c-kit+hematopoietic progenitor cells were magnetically isolated with a MiniMACS separator from BALB/c mice bone marrow cells.These cells were cultured with cytokines GM-CSF,IL-4,and TNFα to induce their maturation.They were analysed by morphological observation,phenotype analysis,and mixed lymphocyte reaction(MLR).Bone marrow-derived DCs(BM-DCs)were pulsed with tumor cell lysate obtained by rapid freezing and thawing at a 1:3 DC:tumor cell ratio.Finally,cytotoxic T lymphocyte (CTL)activity and interferon gamma(IFNγ)secretion was evaluated ex vivo. RESULTS:c-kit+hematopoietic progenitor cells from mice bone marrow cells cultured with cytokines for 8 d showed the character of typical mature DCs.Morphologically,observed by light microscope,these cells were large with oval or irregularly shaped nuclei and with many small dendrites.Phenotypically,FACS analysis showed that they expressed high levels of Ia, DEC-205,CD11b,CD80 and CD86 antigen,moderate levels of CD40,and negative for F4/80.Functionally, these cells gained the capacity to stimulate allogeneic T cells in MLR assay.However,immature DCs cultured with cytokines for 5 d did not have typical DCs phenotypic markers and could not stimulate allogeneic T cells.Ex vivo primed T cells with SGC-7901 tumor cell lysate-pulsed(TP)DCs were able to induce effective CTL activity against SGC-7901 tumor cells (E:T=100:1,69.55%±6.05%specific lysis),but not B16 tumor cells,and produced higher levels of IFNγwhen stimulated with SGC-7901 tumor cells but not when stimulated with BB1166 tumor cells(1575.31±60.25 pg/mL in SGC-7901 group vs 164.11±18.52 pg/mL in B16 group,P<0.01). CONCLUSION:BM-derived DCs pulsed with tumor lysates can induce anti-tumor immunity specific to gastric cancer ex vivo. | Yan-Lin Li Yu-Gang Wu Yong-Qing Wang Zhong Li Rong-Chao Wang Liang Wang Yan-Yun Zhang | 2008 | World Journal of Gastroenterology2008,14,46: | 16 |
| 17 | Seasonal pattern of Echinococcus re-infection in owned dogs in Tibetan communities of Sichuan, China and its implications for control显示文摘Background:Human cystic echinococcosis(CE)and alveolar echinococcosis(AE)are highly endemic in Tibetan communities of Sichuan Province.Previous research in the region indicated that domestic dog was the major source of human infection,and observations indicated that domestic dog could have more access to intermediate hosts of Echinococcus spp.:both domestic livestock(CE)viscera and small mammals(AE),in early winter and again in spring.We hypothesized that there would therefore be a significant increase in the risk of canine infection with Echinococcus spp.in these two seasons and conducted a reinfection study to investigate this further.Methods:Faecal samples were collected from owned dogs in seven townships in Ganze Tibetan Autonomous Prefecture(Sichuan Province,China),and Echinococcus spp.infection status was determined using copro-antigen ELISA.Dogs were sampled in April(spring),July(early summer),September/October(autumn/early winter)and December(winter)in 2009;and in April(spring)2010.Dogs were treated with praziquantel following each of the five sample collections to eliminate any tapeworms.Information on dog sex,age and body weight was also collected.The t-test,Fisher’s exact test,Poisson regression and logistic regression were used to compare means and prevalences,and to identify factors associated with infection status.Results:The proportion of female dogs was significantly lower than that of male dogs;female dogs had significantly higher(22.78%)baseline copro-ELISA prevalence than males(11.88%).Dog body weight,sex,age,county and previous infection status at any sampling point had no influence on the re-infection prevalence in general.Poisson regression did not found a significant influence on the re-infection prevalence due to different deworming/sampling time spans.Dogs exhibited significantly higher re-infection prevalences in spring and early summer of 2009 and in early winter between September/October and December of 2009,suggesting a higher infection pressure in these seasons comparing with other seasons.Conclusion:Following praziquantel treatment,dog body weight,sex,age,county,deworming time span and previous infection status at any sampling point had no influence on the re-infection prevalence in the region in general.The differences between re-infection prevalences were probably due to the seasonality in Echinoccocus spp.infection pressure in the region.Early winter,spring and early summer should be important seasons for optimal dog deworming intervention in these Tibetan communities. | Qian Wang Wen-Jie Yu Bo Zhong Jing-Ye Shang Liang Huang Alexander Mastin Renqingpengcuo Yan Huang Guang-Jia Zhang Wei He Patrick Giraudoux Wei-Ping Wu Philip S.Craig | 2016 | Infectious Diseases of Poverty2016,5,1: | 15 |
| 18 | Irritable bowel syndrome and functional constipation management with integrative medicine: A systematic review显示文摘BACKGROUND Irritable bowel syndrome(IBS)and functional constipation(FC)are two commonly encountered functional gastrointestinal disorders in clinical practice and are usually managed with Western medicines in cooperation with traditional Chinese medicine(TCM)interventions.Although clinical practice guidelines(CPGs)have been developed to assist clinicians with their decisions,there are still gaps in management with regard to integrative medicine(IM)recommendations.AIM To comprehensively review the currently available CPGs and to provide a reference for addressing the gaps in IBS and FC management.METHODS We searched mainstream English and Chinese databases and collected data from January 1990 to January 2019.The search was additionally enriched by manual searches and the use of publicly available resources.Based on the development method,the guidelines were classified into evidence-based(EB)guidelines,consensus-based(CB)guidelines,and consensus-based guidelines with no comprehensive consideration of the EB(CB-EB)guidelines.With regard to the recommendations,the strength of the interventions was uniformly converted to a 4-point grading scale.RESULTS Thirty CPGs met the inclusion criteria and were captured as data extraction sources.Most Western medicine(WM)CPGs were developed as EB guidelines.All TCM CPGs and most IM CPGs were identified as CB guidelines.Only the 2011 IBS and IM CPG was a CB-EB set of guidelines.Antispasmodics and peppermint oil for pain,loperamide for diarrhea,and linaclotide for constipation polyethylene glycol and lactulose as osmotic laxatives,bisacodyl and sodium picosulfate as stimulant laxatives,lubiprostone and linaclotide as prosecretory agents,and prucalopride were strongly recommended or recommended in FC.TCM interventions were suggested based on pattern differentiation,while the recommendation level was considered to be weak or insufficient.CONCLUSION WM CPGs generally provide a comprehensive management algorithm,although there are still some gaps that could be addressed with TCM.Specific high-quality trials are needed to enrich the evidence. | Liang Dai Linda LD Zhong Guang Ji | 2019 | World Journal of Clinical Cases2019,7,21: | 14 |
