| 1 | 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 |
| 2 | Microarray microRNA profiling of urinary exosomes in a 5XFAD mouse model of Alzheimer’s disease显示文摘Background:Alzheimer's disease(AD)is an incurable and irreversible neurodegen-erative disease,without a clear pathogenesis.Therefore,identification of candidates before amyloid-βplaque(Aβ)deposition proceeds is of major significance for earlier intervention in AD.Methods:To explore the potential noninvasive earlier biomarkers of AD in a 5XFAD mouse model,microRNAs(miRNAs)from urinary exosomes in 1-month-old pre-Aβaccumulation 5XFAD mice models and their littermate controls were profiled by mi-croarray analysis.The differentially expressed miRNAs were further analyzed via droplet digital PCR(ddPCR).Results:Microarray analysis demonstrated that 48 differentially expressed miRNAs(18 upregulated and 30 downregulated),of which six miRNAs-miR-196b-5p,miR-339-3p,miR-34a-5p,miR-376b-3p,miR-677-5p,and miR-721-were predicted to display gene targets and important signaling pathways closely associated with AD pathogenesis and verified by ddPCR.Conclusions:Urinary exosomal miRNAs showing differences in expression prior to Aβ-plaque deposition were identified.These exosomal miRNAs represent potential noninvasive biomarkers that may be used to prevent AD in clinical applications. | Zhiqi Song Yajin Qu Yanfeng Xu Ling Zhang Li Zhou Yunlin Han Wenjie Zhao Pin Yu Yu Zhang Xianglei Li Chuan Qin | 2021 | Animal Models and Experimental Medicine2021，4，3： | 6 |
| 3 | Chinese expert consensus on conversion therapy for hepatocellular carcinoma(2021 edition)显示文摘Recent advances in systemic and locoregional treatments for patients with unresectable or advanced hepatocellular carcinoma(HCC)have resulted in improved response rates.This has provided an opportunity for selected patients with initially unresectable HCC to achieve adequate tumor downstaging to undergo surgical resection,a‘conversion therapy’strategy.However,conversion therapy is a new approach to the treatment of HCC and its practice and treatment protocols are still being developed.Review the evidence for conversion therapy in HCC and develop consensus statements to guide clinical practice.Evidence review:Many research centers in China have accumulated significant experience implementing HCC conversion therapy.Preliminary findings and data have shown that conversion therapy represents an important strategy to maximize the survival of selected patients with intermediate stage to advanced HCC;however,there are still many urgent clinical and scientific challenges for this therapeutic strategy and its related fields.In order to summarize and learn from past experience and review current challenges,the Chinese Expert Consensus on Conversion Therapy for Hepatocellular Carcinoma(2021 Edition)was developed based on a review of preliminary experience and clinical data from Chinese and non-Chinese studies in this field and combined with recommendations for clinical practice.Sixteen consensus statements on the implementation of conversion therapy for HCC were developed.The statements generated in this review are based on a review of clinical evidence and real clinical experience and will help guide future progress in conversion therapy for patients with HCC. | Hui-Chuan Sun Jian Zhou Zheng Wang Xiufeng Liu Qing Xie Weidong Jia Ming Zhao Xinyu Bi Gong Li Xueli Bai Yuan Ji Li Xu Xiao-Dong Zhu Dousheng Bai Yajin Chen Yongjun Chen Chaoliu Dai Rongping Guo Wenzhi Guo Chunyi Hao Tao Huang Zhiyong Huang Deyu Li Gang Li Tao Li Xiangcheng Li Guangming Li Xiao Liang Jingfeng Liu Fubao Liu Shichun Lu Zheng Lu Weifu Lv Yilei Mao Guoliang Shao Yinghong Shi Tianqiang Song Guang Tan Yunqiang Tang Kaishan Tao Chidan Wan Guangyi Wang Lu Wang Shunxiang Wang Tianfu Wen Baocai Xing Bangde Xiang Sheng Yan Dinghua Yang Guowen Yin Tao Yin Zhenyu Yin Zhengping Yu Bixiang Zhang Jialin Zhang Shuijun Zhang Ti Zhang Yamin Zhang Yubao Zhang Aibin Zhang Haitao Zhao Ledu Zhou Wu Zhang Zhenyu Zhu Shukui Qin Feng Shen Xiujun Cai Gaojun Teng Jianqiang Cai Minshan Chen Qiang Li Lianxin Liu Weilin Wang Tingbo Liang Jiahong Dong Xiaoping Chen Xuehao Wang Shusen Zheng Jia Fan 无 | 2022 | Hepatobiliary Surgery and Nutrition2022，11，2： | 4 |
| 4 | The APR triangle:A practical zone in the Glissonean approach to laparoscopic anatomical right hepatectomy显示文摘Background:An understanding of vascular anatomy is crucial for the safe performance of laparoscopic anatomical liver excision.We discovered a triangular zone during the laparoscopic right liver surgery and termed this zone the APR triangle.The purpose of this study was to determine the probability of the existence of the APR triangle and elucidate its various forms.Methods:Analyzed three-dimensional image reconstructions of 66 individuals who underwent liver surgery and calculated the statistics for various types of APR triangles under various grouping settings.Results:The APR triangle was present in the majority of cases,with right hepatic vein trunk type in 68%and right hepatic vein branch type in 21%,respectively.The angle between the right anterior and right posterior hepatic pedicles(AP&PP)was at most between 45 and 90°(74%).There was a 35%chance that at least one of the AP&PP was longer than 2 cm,and a 39%chance that both were.The right posterior pedicle first branch would appear at the bifurcation of AP&PP in 13%only.Conclusions:The APR triangle is objectively present and may represent a practical zone for performing laparoscopic right hepatic anatomical resection more simply and safely. | Jie Chen Ziyu Zhang Rui Zhou Anzhi Wang Jun Cao Yajin Chen | 2022 | iLIVER2022，1，3： | 2 |
| 5 | SARS-CoV-2 treatment effects induced by ACE2-expressing microparticles are explained by the oxidized cholesterolincreased endosomal pH of alveolar macrophages显示文摘Exploring the cross-talk between the immune system and advanced biomaterials to treat SARS-CoV-2 infection is a promising strategy.Here,we show that ACE2-overexpressing A549 cell-derived microparticles(AO-MPs)are a potential therapeutic agent against SARS-CoV-2 infection.Intranasally administered AO-MPs dexterously navigate the anatomical and biological features of the lungs to enter the alveoli and are taken up by alveolar macrophages(AMs).Then,AO-MPs increase the endosomal pH but decrease the lysosomal pH in AMs,thus escorting bound SARS-CoV-2 from phago-endosomes to lysosomes for degradation.This pH regulation is attributable to oxidized cholesterol,which is enriched in AO-MPs and translocated to endosomal membranes,thus interfering with proton pumps and impairing endosomal acidification.In addition to promoting viral degradation,AO-MPs also inhibit the proinflammatory phenotype of AMs,leading to increased treatment efficacy in a SARS-CoV-2-infected mouse model without side effects.These findings highlight the potential use of AO-MPs to treat SARS-CoV-2-infected patients and showcase the feasibility of MP therapies for combatting emerging respiratory viruses in the future. | Zhenfeng Wang Jiadi Lv Pin Yu Yajin Qu Yabo Zhou Li Zhou Qiangqiang Zhu Shunshun Li Jiangping Song Wei Deng Ran Gao Yuying Liu Jiangning Liu Wei-Min Tong Chuan Qin Bo Huang | 2022 | Cellular & Molecular Immunology2022，19，2： | 1 |

| 7 | A survey of Intel SGX and its applications显示文摘This paper presents a comprehensive survey on the development of Intel SGX(software guard extensions)processors and its applications.With the advent of SGX in 2013 and its subsequent development,the corresponding research works are also increasing rapidly.In order to get a more comprehensive literature review related to SGX,we have made a systematic analysis of the related papers in this area.We first search through five large-scale paper retrieval libraries by keywords(i.e.,ACM Digital Library,IEEE/IET Electronic Library,SpringerLink,Web of Science,and Elsevier Science Direct).We read and analyze a total of 128 SGX-related papers.The first round of extensive study is conducted to classify them.The second round of intensive study is carried out to complete a comprehensive analysis of the paper from various aspects.We start with the working environment of SGX and make a conclusive summary of trusted execution environment(TEE).We then focus on the applications of SGX.We also review and study multifarious attack methods to SGX framework and some recent security improvements made on SGX.Finally,we summarize the advantages and disadvantages of SGX with some future research opportunities.We hope this review could help the existing and future research works on SGX and its application for both developers and users. | Wei ZHENG Ying WU Xiaoxue WU Chen FENG Yulei SUI Xiapu LUO Yajin ZHOU | 2021 | Frontiers of Computer Science2021，15，3： | 1 |
| 8 | Molecular identification and biochemical characteristics of a delta class glutathione S-transferase gene(FcδGST)from Chinese shrimp Fenneropenaeus chinensis显示文摘Glutathione S-transferases(GSTs)are a superfamily of multifunction enzymes involved in the regulation of redox homeostasis and innate immune responses against various pathogenic infections in marine invertebrates.In the present study,a delta class GST gene(designated as FcδGST)was cloned from Fenneropenaeus chinensis using rapid amplification of c DNA ends(RACE)technology.The complete cDNA sequence of FcδGST was 780 bp in length,which includes a 27-bp 5′non-coding region(UTR),a 117-bp 3′UTR,a 636-bp open reading frame(ORF),and a polyadenylate signal site(AATAAA)presented at the upstream of poly A tail.The FcδGST gene encoded 211 amino acids peptide,including a GST_N domain and a GST_C domain,and exhibited high similarity with previously reported delta GSTs.The predicted molecular mass of FcδGST protein was 23.39 kDa,and its theoretical isoelectric point(pI)was 5.34.The FcδGST mRNA transcripts were ubiquitously expressed in all the tested tissues,with the highest expression level in hemocytes and hepatopancreas.During the stimulation of Vibrio anguillarum or white spot syndrome virus(WSSV),the m RNA expression of FcδGST in hemocytes and hepatopancreas revealed significant up-regulation.The purified recombinant FcδGST protein(designated as rFcδGST)exhibited specific catalytic activity against 1-chloro-2,4-dinitrobenzene(CDNB)substrate with relatively low stable enzymatic activities.These results indicated that FcδGST was a fragile but typical novel delta class GST member and potentially involved in the innate immune responses of F.chinensis. | Jiaobing LI Yan WANG Jingjie HU Yajin XU Qingqian ZHOU Lu ZHANG Mengqiang WANG | 2023 | Journal of Oceanology and Limnology2023，41，5： | 0 |
| 9 | Tolerance and acceptance of hepatic venous pressure gradient measurement in cirrhosis(CHESS1904):An international multicenter study显示文摘Aim:To determine the tolerance and acceptance of hepatic venous pressure gradient(HVPG)measurements in patients with liver cirrhosis.Methods:This prospective international multicenter study included 271 patients with cirrhosis who were scheduled to undergo HVPG measurement between October 2019 and June 2020.Data related to the tolerance and acceptance of HVPG measurements were collected using descriptive questionnaires.Results:HVPG measurements were technically successful in all 271 patients,with 141(52.0%)undergoing HVPG measurement alone.The complication rate was 0.4%.Postoperative pain was significantly lower than preoperative expected pain(p<0.001)and intraoperative pain(p<0.001),and intraoperative pain was also significantly lower than preoperative expected pain(p=0.036).No,mild,moderate,severe,and intolerable discomfort scores were reported by 36.9%,44.6%,11.1%,6.3%,and 0.4%of these patients,respectively,during HVPG measurement and by 54.6%32.5%,11.4%,1.5%,and 0%,respectively,after HVPG measurement.Of these patients,39.5%had little understanding and 10%had no understanding of the value of HVPG measurement,with 35.1%and 4.1%regarding HVPG measurements as being of little or no help,respectively.Most patients reported that they would definitely(15.5%),probably(46.9%),or possibly(29.9%)choose to undergo additional HVPG measurements again,and 62.7%regarded the cost of the procedure as acceptable.Conclusion:HVPG measurement was safe and well‐tolerated in patients with cirrhosis,but patient education and communication are warranted to improve the acceptance of this procedure. | Jun‐Hui Sun He Zhao Haijun Zhang Lei Li NecatiÖrmeci Zi‐Niu Yu Xun Li Shuangxi Li Xujun Yang Huaping Wei Xiaoliang Zhu Zhengcong Zhang Yajin Wang Zhongwei Zhao Jianting Mao Qiaohong Wu Xiaole Sun Huiling Xiang Kefeng Jia Chao Yang Wei Wu Xiuqing Lin Haixin Yao Changzeng Zuo Jitao Wang Bo Zhang Chunqing Zhang Xiaoling Wu Guangchuan Wang Shengjuan Yao Ruihang Wang Li Zhou Hui Huan Qingli Tu Xue Pu Feng Zhang Qin Yin Linpeng Zhang Ying Guo Jian Wang Kohei Kotani Sawako Uchida‐Kobayashi Norifumi Kawada He Zhu Li Li Wei Wang Guo Zhang Lei Yu Xudong Cui Qingliang Zhu Hailong Zhang Xiaoli Hu Rafael OXimenes Adriano Gonçalves de Araújo Giulliano Gardenghi Yubao Zheng Zebin Wu Mingsheng Huang Xiaoyong Chen Jun Wu Feng Xie Yang Bo Shengjuan Hu Linke Ma Xiao Li Xiaolong Qi | 2022 | Portal Hypertension & Cirrhosis2022，1，1： | 0 |
