| 3 | Hypoxia-inducible factor 2α is a negative regulator of osteoblastogenesis and bone mass accrual显示文摘Osteoblasts,which are the bone-forming cells,operate in a hypoxic environment.The transcription factors hypoxia-inducible factor-1α(HIF1)and HIF2 are key mediators of the cellular response to hypoxia.Both are expressed in osteoblasts.HIF1 is known to be a positive regulator of bone formation.Conversely,the role of HIF2 in the control osteoblast biology is still poorly understood.In this study,we used mouse genetics to demonstrate that HIF2 is an inhibitor of osteoblastogenesis and bone mass accrual.Moreover,we provided evidence that HIF2 impairs osteoblast differentiation at least in part,by upregulating the transcription factor Sox9.Our findings constitute a paradigm shift,as activation of the hypoxia-signaling pathway has traditionally been associated with increased bone formation through HIF1.Inhibiting HIF2 could thus represent a therapeutic approach for the treatment of the low bone mass observed in chronic diseases,osteoporosis,or aging. | Christophe Merceron Kavitha Ranganathan Elizabeth Wang Zachary Tata Shreya Makkapati Mohd Parvez Khan Laura Mangiavini Angela Qing Yao Laura Castellini Benjamin Levi Amato J.Giaccia Ernestina Schipani | 2019 | Bone Research2019，7，1： | 7 |
| 4 | Advanced endoscopic imaging of indeterminate biliary strictures显示文摘Endoscopic evaluation of indeterminate biliary stric-tures(IDBSs) has evolved considerably since the development of flexible fiberoptic endoscopes over 50 years ago. Endoscopic retrograde cholangiography pancreatography(ERCP) was introduced nearly a decade later and has since become the mainstay of therapy for relieving obstruction of the biliary tract. However, longstanding methods of ERCP-guided tissue acquisition(i.e., biliary brushings for cytology and intraductal forceps biopsy for histology) have demon-strated disappointing performance characteristics in distinguishing malignant from benign etiologies of IDBSs. The limitations of these methods have thus helped drive the search for novel techniques to enhance the evaluation of IDBSs and thereby improve diagnosis and clinical care. These modalities include, but are not limited to, endoscopic ultrasound, intraductal ultrasound, cholangioscopy, confocal endomicroscopy, and optical coherence tomography. In this review, we discuss established and emerging options in the evaluation of IDBSs. | James H Tabibian Kavel H Visrodia Michael J Levy Christopher J Gostout | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，18： | 6 |

| 7 | Comparison of alternative arterial anastomosis site during liver transplantation when the recipient’s hepatic artery is unusable显示文摘Background:Few studies have analyzed outcomes of liver transplantation(LT)when the recipient hepatic artery(HA)was not usable.Methods:We retrospectively evaluated the outcomes of LT performed using the different alternative sites to HA.Results:Between 2002 and 2017,1,677 LT were performed in our institution among which 141(8.4%)with unusable recipient HA were analyzed.Four groups were defined according to the site of anastomosis:the splenic artery(SA group,n=26),coeliac trunk(CT group,n=12),aorta using or not the donor’s vessel(Ao group,n=91)and aorta using a vascular prosthesis(Ao-P group,n=12)as conduit.The median number of intraoperative red blood cell transfusions was significantly increased in the Ao and Ao-P groups(5,5,8.5 and 16 for SA,CT,Ao and Ao-P group respectively,P=0.002),as well as fresh frozen plasma(4.5,2.5,10,17 for the SA,CT,Ao and Ao-P groups respectively,P=0.001).Hospitalization duration was also significantly increased in the Ao and Ao-P groups(15,16,24,26.5 days for the SA,CT,Ao and Ao-P groups respectively,P<0.001).The occurrence of early allograft dysfunction(EAD)(P=0.07)or arterial complications(P=0.26)was not statistically different.Level of factor V,INR,bilirubin and creatinine during the 7th postoperative days(POD)was significantly improved in the SA group.No difference was observed regarding graft(P=0.18)and patient(P=0.16)survival.Conclusions:In case of unusable HA,intraoperative and postoperative outcomes are improved when using the SA or CT compared to aorta. | Jean Marie Beaurepaire Francesco Orlando Giovanni Battista Levi Sandri Caroline Jezequel Edouard Bardou-Jacquet Christophe Camus Mohamed Lakehal Veronique Desfourneaux Aude Merdrignac Elodie Gaignard Alexandre Thobie Damien Bergeat Bernard Meunier Michel Rayar | 2022 | Hepatobiliary Surgery and Nutrition2022，11，1： | 3 |
| 8 | 一种房颤风险评分系统的建立(Framingham心脏研究):基于社区的队列研究显示文摘背景房颤导致了发病率和病死率的显著上升。本研究旨在建立一种预测个体罹患房颤绝对风险的风险评分系统,并提供研究人员评价新危险因素的流程。方法作者评估了Framingham心脏研究中于1968年6月至1987年9月间进行了8044次检测的4764例参与者(55%为女性,年龄45~95岁)。此后,参与者被随访至房颤首发,随访期最长达10年。多变量Coxi回归确认出1(1年内罹患房颤的临床危险因素。次级分析纳入了常规超声心动图检测指标(5152例4参与者,7156次检测)对房颤风险进行再分层评估,并评价超声检测指标能否提高风险预测能力。结果4764例参与者中的457例4(10%)罹患房颤。年龄、性别、体重指数、收缩压、降压治疗、PR间期、有临床意义的心脏杂音及心力衰竭与房颤相关,并被纳入了风险评分模型(除体重指数P=0.08外,其余均为P〈0.05),模型的C统计量为0.78(95%CI0.76~0.80)。10年房颤风险随年龄变化:年龄〈65岁的人群中53例(1%)风险高于15%,而〉65岁的人群中为783例(27%)。为提高预测能力而纳入超声检测指标仅使模型C统计量略微增高,由0.78(95%C10.75~0.80)增至0.79(95%CI0.77~0.82:P=0.005)。超声心动图检测指标并不能改善风险再分层评估(P=0.18)。结论基于社区医疗中易得的临床因素建立的风险评分系统,有助于确认社区个体罹患房颤的风险,评估技术或标志物能否改善风险预测,以及针对高危个体采取预防措施。 | Renate B Schnabel Lisa M Sullivan Daniel Levy Michael J Pencina Joseph M Massaro Ralph B D'Agostino Sr Christopher Newton-Cheh Jennifer F Yamamoto Jared W Magnani Thomas M Tadros William B Kannel Thomas J Wang Patrick T Ellinor Philip A Wolf Ramachanclran S Vasan Emelia J Benjamin 黄刚(译) | 2009 | 世界临床医学2009，，9： | 2 |

| 10 | Macrophage-specific inhibition of the histone demethylase JMJD3 decreases STING and pathologic inflammation in diabetic wound repair显示文摘Macrophage plasticity is critical for normal tissue repair following injury.In pathologic states such as diabetes,macrophage plasticity is impaired,and macrophages remain in a persistent proinflammatory state;however,the reasons for this are unknown.Here,using single-cell RNA sequencing of human diabetic wounds,we identified increased JMJD3 in diabetic wound macrophages,resulting in increased inflammatory gene expression.Mechanistically,we report that in wound healing,JMJD3 directs early macrophage-mediated inflammation via JAK1,3/STAT3 signaling.However,in the diabetic state,we found that IL-6,a cytokine increased in diabetic wound tissue at later time points post-injury,regulates JMJD3 expression in diabetic wound macrophages via the JAK1,3/STAT3 pathway and that this late increase in JMJD3 induces NFκB-mediated inflammatory gene transcription in wound macrophages via an H3K27me3 mechanism.Interestingly,RNA sequencing of wound macrophages isolated from mice with JMJD3-deficient myeloid cells(Jmjd3f/fLyz2Cre+)identified that the STING gene(Tmem173)is regulated by JMJD3 in wound macrophages.STING limits inflammatory cytokine production by wound macrophages during healing.However,in diabetic mice,its role changes to limit wound repair and enhance inflammation.This finding is important since STING is associated with chronic inflammation,and we found STING to be elevated in human and murine diabetic wound macrophages at late time points.Finally,we demonstrate that macrophage-specific,nanoparticle inhibition of JMJD3 in diabetic wounds significantly improves diabetic wound repair by decreasing inflammatory cytokines and STING.Taken together,this work highlights the central role of JMJD3 in tissue repair and identifies cell-specific targeting as a viable therapeutic strategy for nonhealing diabetic wounds. | Christopher O.Audu William J.Melvin Amrita D.Joshi Sonya J.Wolf Jadie Y.Moon Frank M.Davis Emily C.Barrett Kevin D.Mangum Hongping Deng Xianying Xing Rachel Wasikowski Lam C.Tsoi Sriganesh B.Sharma Tyler M.Bauer James Shadiow Matthew A.Corriere Andrea TObi Steven LKunkel Benjamin Levi Bethany BMoore Johann EGudjonsson Andrew MSmith Katherine A.Gallagher | 2022 | Cellular & Molecular Immunology2022，19，11： | 2 |

| 18 | Tranexamic acid for intracerebral haemorrhage within 2 hours of onset: protocol of a phase Ⅱ randomised placebo-controlled double-blind multicentre trial显示文摘Rationale Haematoma growth is common early after intracerebral haemorrhage(ICH),and is a key determinant of outcome.Tranexamic acid,a widely available antifibrinolytic agent with an excellent safety profile,may reduce haematoma growth.Methods and design Stopping intracerebral haemorrhage with tranexamic acid for hyperacute onset presentation including mobile stroke units(STOP-MSU)is a phase Ⅱ double-blind,randomised,placebo-controlled,multicentre,international investigator-led clinical trial,conducted within the estimand statistical framework.Hypothesis In patients with spontaneous ICH,treatment with tranexamic acid within 2 hours of onset will reduce haematoma expansion compared with placebo.Sample size estimates A sample size of 180 patients(90 in each arm)would be required to detect an absolute difference in the primary outcome of 20%(placebo 39%vs treatment 19%)under a two-tailed significance level of 0.05.An adaptive sample size re-estimation based on the outcomes of 144 patients will allow a possible increase to a prespecified maximum of 326 patients.Intervention Participants will receive 1 g intravenous tranexamic acid over 10 min,followed by 1 g intravenous tranexamic acid over 8 hours;or matching placebo.Primary efficacy measure The primary efficacy measure is the proportion of patients with haematoma growth by 24±6 hours,defined as either≥33%relative increase or≥6 mL absolute increase in haematoma volume between baseline and follow-up CT scan.Discussion We describe the rationale and protocol of STOP-MSU,a phase Ⅱ trial of tranexamic acid in patients with ICH within 2 hours from onset,based in participating mobile stroke units and emergency departments. | Nawaf Yassi Henry Zhao Leonid Churilov Bruce C V Campbell Teddy Wu Henry Ma Andrew Cheung Timothy Kleinig Helen Brown Philip Choi Jiann-Shing Jeng Annemarei Ranta Hao-Kuang Wang Geoffrey C Cloud Rohan Grimley Darshan Shah Neil Spratt Der-Yang Cho Karim Mahawish Lauren Sanders John Worthington Ben Clissold Atte Meretoja Vignan Yogendrakumar Mai Duy Ton Duc Phuc Dang Nguyen Thai My Phuong Huy-Thang Nguyen Chung Y Hsu Gagan Sharma Peter J Mitchell Bernard Yan Mark W Parsons Christopher Levi Geoffrey A Donnan Stephen M Davis | 2022 | Stroke & Vascular Neurology2022，7，2： | 1 |
