| 1 | Bile duct injuries associated with laparoscopic and open cholecystectomy: Sixteen-year experience显示文摘AIM: To summarize the experience in diagnosis, management and prevention of iatrogenic bile duct injury (IBDI). METHODS: A total of 210 patients with bile duct injury occurred during cholecystectomy admitted to Hunan Provincial People’s Hospital from March 1990 to March 2006 were included in this study for retrospective analysis. RESULTS: There were 59.5% (103/173) of patients with IBDI resulting from the wrong identification of the anatomy of the Calot’s triangle during cholecystectomy. The diagnosis of IBDI was made on the basis of clinical features, diagnostic abdominocentesis and imaging findings. Abdominal B ultrasonography (BUS) was the most popular way for IBDI with a diagnostic rate of 84.6% (126/149). Magnetic resonance cholangiography (MRC) could reveal the site of injury, the length of injured bile duct and variation of bile duct tree with a diagnostic rate 100% (45/45). According to the site of injury, IBDI could be divided into six types. The most common type (type 3) occurred in 76.7% (161/210) of the patients and was treated with partial resection of the common hepatic duct and common bile duct. One hundred and seventy-six patients were followed up. The mean follow-up time was 3.7 (range 0.25-10) years. Good results were achieved in 87.5% (154/176) of the patients. CONCLUSION: The key to prevention of IBDI is to follow the 'identifying-cutting-identifying' principle during cholecystectomy. Re-operation time and surgical procedure are decided according to the type of IBDI. | Jin-Shu Wu Chuang Peng Xian-Hai Mao Pin Lv | 2007 | World Journal of Gastroenterology2007，13，16： | 32 |
| 2 | Age-related rhesus macaque models of COVID-19显示文摘Background:Since December 2019,an outbreak of the Corona Virus disease 2019(COVID-19)caused by severe acute respiratory syndrome coronavirus(SARS-CoV-2)in Wuhan,China,has become a public health emergency of international concern.The high fatality of aged cases caused by SARS-CoV-2 was a need to explore the possible age-related phenomena with non-human primate models.Methods:Three 3-5 years old and two 15 years old rhesus macaques were intratracheally infected with SARS-CoV-2,and then analyzed by clinical signs,viral replication,chest X-ray,histopathological changes and immune response.Results:Viral replication of nasopharyngeal swabs,anal swabs and lung in old monkeys was more active than that in young monkeys for 14 days after SARS-CoV-2 challenge.Monkeys developed typical interstitial pneumonia characterized by thickened alveolar septum accompanied with inflammation and edema,notably,old monkeys exhibited diffuse severe interstitial pneumonia.Viral antigens were detected mainly in alveolar epithelial cells and macrophages.Conclusion:SARS-CoV-2 caused more severe interstitial pneumonia in old monkeys than that in young monkeys.Rhesus macaque models infected with SARS-CoV-2 provided insight into the pathogenic mechanism and facilitated the development of vaccines and therapeutics against SARS-CoV-2 infection. | Pin Yu Feifei Qi Yanfeng Xu Fengdi Li Peipei Liu Jiayi Liu Linlin Bao Wei Deng Hong Gao Zhiguang Xiang Chong Xiao Qi Lv Shuran Gong Jiangning Liu Zhiqi Song Yajin Qu Jing Xue Qiang Wei Mingya Liu Guanpeng Wang Shunyi Wang Haisheng Yu Xing Liu Baoying Huang Wenling Wang Li Zhao Huijuan Wang Fei Ye Weimin Zhou Wei Zhen Jun Han Guizhen Wu Qi Jin Jianwei Wang Wenjie Tan Chuan Qin | 2020 | Animal Models and Experimental Medicine2020，3，1： | 22 |
| 3 | Expression of circulating microRNA-20a and let-7a in esophageal squamous cell carcinoma显示文摘AIM: To investigate the expressions of micro RNA-20a(mi R-20a) and let-7a in esophageal squamous cell carcinoma(ESCC) and their diagnostic value. METHODS: Seventy patients with ESCC and 40 healthy subjects were enrolled to investigate the expression of mi R-20 a and let-7a using quantitative real-time PCR. The expression of mi R-20 a and let-7a was compared between ESCC patients and healthy subjects. The plasma levels of mi R-20 a and let-7a in relation to patient clinicopathologic parameters, the receiver operating characteristic(ROC) curve, and the sensitivity and specificity of mi R-20 a and let-7a in ESCC diagnosis were analyzed.RESULTS: Plasma levels of mi R-20 a were significantly higher in ESCC patients than in healthy controls, and plasma levels of let-7 were lower in ESCC patients than in healthy controls(both P < 0.05). The area under the ROC curve of mi R-20 a was 0.767(95%CI: 0.677-0.857; P < 0.001), when the cut-off value was set at 4.77, the sensitivity and specificity were 64.3% and 75.0%, respectively. The area under the ROC curve of let-7a was 0.829(95%CI: 0.754-0.904; P < 0.001), when the cut-off value was set at 6.22, the sensitivity and specificity were 74.3% and 85.0%, respectively. Thus, the sensitivity and specificity of let-7a were higher than those of mi R-20 a. The median relative plasma expression of let-7a in clinical stage Ⅲ/Ⅳ(0.24) was lower than that in stage Ⅰ/Ⅱ(0.42), while the expression of mi R-20 a according to stage was not statistically different. The expressions of mi R-20 a and let-7a were not related to gender, age, tumor diameter, tumor grade, or pathologic stage.CONCLUSION: Plasma mi R-20 a and let-7a levels are significantly altered in patients with ESCC and can be used as potential biomarkers in the diagnosis of ESCC. | Fu-Cheng He Wei-Wei Meng Yun-Hui Qu Ming-Xia Zhou Jing He Pin Lv Liang Ming | 2015 | World Journal of Gastroenterology2015，21，15： | 6 |

| 5 | Sequential infection with H1N1 and SARS-CoV-2 aggravated COVID-19 pathogenesis in a mammalian model, and covaccination as an effective method of prevention of COVID-19 and influenza显示文摘Influenza A virus may circulate simultaneously with the SARS-CoV-2 virus,leading to more serious respiratory diseases during this winter.However,the influence of these viruses on disease outcome when both influenza A and SARS-CoV-2 are present in the host remains unclear.Using a mammalian model,sequential infection was performed in ferrets and in K18-MCE2 mice,with SARS-CoV-2 infection following H1N1.We found that co-infection with H1N1 and SARS-CoV-2 extended the duration of clinical manifestation of COVID-19,and enhanced pulmonary damage,but reduced viral shedding of throat swabs and viral loads in the lungs of ferrets.Moreover,mortality was increased in sequentially infected mice compared with single-infection mice.Compared with singlevaccine inoculation,co-inoculation of PiCoVacc(a SARS-CoV-2 vaccine)and the flu vaccine showed no significant differences in neutralizing antibody titers or virus-specific immune responses.Combined immunization effectively protected K18-MCE2 mice against both H1N1 and SARS-CoV-2 infection.Our findings indicated the development of systematic models of co-infection of H1N1 and SARS-CoV-2,which together notably enhanced pneumonia in ferrets and mice,as well as demonstrated that simultaneous vaccination against HINT and SARS-CoV-2 may be an effective prevention strategy for the coming winter. | Linlin Bao Wei Deng Feifei Qi Qi Lv Zhiqi Song Jiangning Liu Hong Gao Qiang Wei Pin Yu Yanfeng Xu Yajin Qu Fengdi Li Jing Xue Shuran Gong Mingya Liu Guanpeng Wang Shunyi Wang Binbin Zhao Bin Cong Chuan Qin | 2021 | Signal Transduction and Targeted Therapy2021，6，6： | 4 |
| 6 | Homologous fault monitoring technology of redundant INS in airborne avionics systems显示文摘Redundant technology plays an important role in improving the reliability and fault-tolerance of the airborne avionics systems.A Markov state transition model is introduced to the reliability analysis of the redundant inertial navigation system (RINS) in airborne navigation systems.An information processing mechanism based on difference filtering is put forward to strengthen the consistency between the outputs of the equal-precision inertia navigation system (INS).On this basis,the homologous fault monitoring algorithm is designed to realize the homologous fault monitoring of RINS.The simulation is carried out based on the above algorithms,and the results verify the effectiveness of the proposed fault monitoring algorithm based on difference filtering.Research results have good reference value for the configuration and design of RINS in airborne integrated avionics systems. | Xiuzhi Wu Jizhou Lai Min Liu Pin Lv | 2013 | Journal of Systems Engineering and Electronics2013，24，6： | 4 |
| 7 | Integrated histopathological,lipidomic,and metabolomic profiles reveal mink is a useful animal model to mimic the pathogenicity of severe COVID-19 patients显示文摘Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)is transmitted on mink farms between minks and humans in many countries.However,the systemic pathological features of SARS-CoV-2-infected minks are mostly unknown.Here,we demonstrated that minks were largely permissive to SARS-CoV-2,characterized by severe and diffuse alveolar damage,and lasted at least 14 days post inoculation(dpi).We first reported that infected minks displayed multiple organ-system lesions accompanied by an increased inflammatory response and widespread viral distribution in the cardiovascular,hepatobiliary,urinary,endocrine,digestive,and immune systems.The viral protein partially co-localized with activated Mac-2+macrophages throughout the body.Moreover,we first found that the alterations in lipids and metabolites were correlated with the histological lesions in infected minks,especially at 6 dpi,and were similar to that of patients with severe and fatal COVID-19.Particularly,altered metabolic pathways,abnormal digestion,and absorption of vitamins,lipids,cholesterol,steroids,amino acids,and proteins,consistent with hepatic dysfunction,highlight metabolic and immune dysregulation.Enriched kynurenine in infected minks contributed to significant activation of the kynurenine pathway and was related to macrophage activation.Melatonin,which has significant anti-inflammatory and immunomodulating effects,was significantly downregulated at 6 dpi and displayed potential as a targeted medicine.Our data first illustrate systematic analyses of infected minks to recapitulate those observations in severe and fetal COVID-19 patients,delineating a useful animal model to mimic SARS-CoV-2-induced systematic and severe pathophysiological features and provide a reliable tool for the development of effective and targeted treatment strategies,vaccine research,and potential biomarkers. | Zhiqi Song Linlin Bao Wei Deng Jiangning Liu Erjun Ren Qi Lv Mingya Liu Feifei Qi Ting Chen Ran Deng Fengdi Li Yunpeng Liu Qiang Wei Hong Gao Pin Yu Yunlin Han Wenjie Zhao Junjun Zheng Xujian Liang Fuhe Yang Chuan Qin | 2022 | Signal Transduction and Targeted Therapy2022，7，2： | 2 |
| 8 | Sequential immunizations confer cross-protection against variants of SARS-CoV-2,including Omicron in Rhesus macaques显示文摘Variants of concern(VOCs)like Delta and Omicron,harbor a high number of mutations,which aid these viruses in escaping a majority of known SARS-CoV-2 neutralizing antibodies(NAbs).In this study,Rhesus macaques immunized with 2-dose inactivated vaccines(Coronavac)were boosted with an additional dose of homologous vaccine or an RBD-subunit vaccine,or a bivalent inactivated vaccine(Beta and Delta)to determine the effectiveness of sequential immunization.The booster vaccination significantly enhanced the duration and levels of neutralizing antibody titers against wild-type. | Wei Deng Qi Lv Fengdi Li Jiangning Liu Zhiqi Song Feifei Qi Qiang Wei Pin Yu Mingya Liu Shasha Zhou Yaqing Zhang Hong Gao Nan Wang Zijing Jia Kai Gao Jiayi Liu Chong Xiao Haiquan Shang Xiangxi Wang Linlin Bao Chuan Qin | 2022 | Signal Transduction and Targeted Therapy2022，7，5： | 2 |
| 9 | SARS-CoV-2 crosses the blood-brain barrier accompanied with basement membrane disruption without tight junctions alteration显示文摘SARS-CoV-2 has been reported to show a capacity for invading the brains of humans and model animals.However,it remains undear whether and how SARS-CoV-2 crosses the blood-brain barrier(BBB).Herein,SARS-CoV-2 RNA was occasionally detected in the vascular wall and perivascular space,as well as in brain microvascular endothelial cells(BMECs)in the infected K18-hACE2 transgenic mice.Moreover,the permeability of the infected vessel was in creased.Furthermore,disin tegrity of BBB was discovered in the infected hamsters by administration of Evans blue.Interestingly,the expression of claudin5,ZO-1,occludin and the ultrastructure of tight junctions(TJs)showed unchanged,whereas,the basement membrane was disrupted in the infected animals.Using an in vitro BBB model that comprises primary BMECs with astrocytes,SARS-CoV-2 was found to infect and cross through the BMECs.Consistent with in vivo experiments,the expression of MMP9 was increased and collagen IV was decreased while the markers for TJs were not altered in the SARS-CoV-2-infected BMECs.Besides,inflammatory responses including vasculitis,glial activation,and upregulated inflammatory factors occurred after SARS-CoV-2 infection.Overall,our results provide evidence supporting that SARS-CoV-2 can cross the BBB in a transcellular pathway accompanied with basement membrane disrupted without obvious alteration of TJs. | Ling Zhang Li Zhou Linlin Bao Jiangning Liu Hua Zhu Qi Lv Ruixue Liu Wei Chen Wei Tong Qiang Wei Yanfeng Xu Wei Deng-Hong Gao Jing Xue Zhiqi Song Pin Yu Yunlin Han Yu Zhang Xiuping Sun Xuan Yu Chuan Qin | 2021 | Signal Transduction and Targeted Therapy2021，6，10： | 2 |
| 10 | Antrodia cinnamomea exerts an anti-hepatoma effect by targeting PI3K/AKT-mediated cell cycle progression in vitro and in vivo显示文摘Antrodia cinnamomea is extensively used as a traditional medicine to prevention and treatment of liver cancer.However,its comprehensive chemical fingerprint is uncertain,and the mechanisms,especially the potential therapeutic target for anti-hepatocellular carcinoma(HCC)are still unclear.Using UPLC-Q-TOF/MS,139 chemical components were identified in A.cinnamomea dropping pills(ACDPs).Based on these chemical components,network pharmacology demonstrated that the targets of active components were significantly enriched in the pathways in cancer,which were closely related with cell proliferation regulation.Next,HCC data was downloaded from Gene Expression Omnibus database(GEO).The Cancer Genome Atlas(TCGA)and Dis Ge NET were analyzed by bioinformatics,and 79 biomarkers were obtained.Furtherly,nine targets of ACDP active components were revealed,and they were significantly enriched in PI3 K/AKT and cell cycle signaling pathways.The affinity between these targets and their corresponding active ingredients was predicted by molecular docking.Finally,in vivo and in vitro experiments showed that ACDPs could reduce the activity of PI3 K/AKT signaling pathway and downregulate the expression of cell cycle-related proteins,contributing to the decreased growth of liver cancer.Altogether,PI3 K/AKT-cell cycle appears as the significant central node in anti-liver cancer of A.Cinnamomea. | Yan Zhang Pin Lv Junmei Ma Ning Chen Huishan Guo Yan Chen Xiaoruo Gan Rong Wang Xuqiang Liu Sufang Fan Bin Cong Wenyi Kang | 2022 | Acta Pharmaceutica Sinica B2022，12，2： | 2 |

| 15 | ACE2 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 | 2021 | Cellular & Molecular Immunology2021，18，5： | 1 |
