4氮沉降的全球化:对于陆地生态系统的意义显示文摘人类活动产生的氮(N),包括农田氮肥施肥和矿物燃料燃烧过程中所固定的氮,其来源和分布正在迅速地扩展到全球范围。这部分氮进入到陆地生态系统中,将会促进植物的生长,并产生过量的氮,最终通过淋溶和痕量气体排放的形式,增加了氮的损失。在某种情况下,还会导致物种组成的变化和生态系统功能的衰减。但并非所有的生态系统都对氮沉降具有类似的响应。它们的响应情况,取决于氮沉降的连续性、生态系统的类型、生态系统对氮的需求或保持能力、土地利用的历史、土壤状况、地形条件、气候背景以及氮沉降的速度、时间和类型等因素。我们认为,起重要作用的是:一些对人类影响具有显著意义的条件、一些控制生态系统响应变化的因素以及一些由于资料缺乏而使不确定性增大的地方。Pamela Matson Kathleen A.Lohse Sharon J.Hall 闵庆文 2002AMBIO-人类环境杂志2002,31,2:71
5Diagnosis of ectopic pancreas by endoscopic ultrasound with fine-needle aspiration显示文摘AIM:To study the clinical,endoscopic,sonographic,and cytologic features of ectopic pancreas(EP).METHODS:This was a retrospective study performedat an academic referral center including two hospitals.Institutional review board approval was obtained.Patients referred to the University Hospital or Denver Health Medical Center Gastrointestinal Endoscopy Lab for gastroduodenal subepithelial lesions(SEL)with a final diagnosis of EP between January 2009and December 2013 were identified.Patients in this group were selected for the study if they underwent endoscopic ultrasound(EUS)with fine-needle aspiration(FNA)or deep biopsy.A review of the medical record was performed specifically to review the following information:presenting symptoms,endoscopic and EUS findings,computed tomography or magnetic resonance imaging findings,pathology results,procedure-related adverse events,and subsequent treatments after EUSFNA.EUS with FNA or deep submucosal biopsy was performed in all patients on an outpatient basais by one of two physicians(Attwell A,Fukami N).Review of all subsequent clinic notes and operative reports was performed in order to determine follow-up and final diagnoses.RESULTS:Between July 2009 and December 2013,10patients[3 males,7 females,median age 52(26-64)years]underwent EUS for a gastroduodenal SEL and were diagnosed with EP.One patient was symptomatic.Six(60%)lesions were in the antrum,3(30%)in the body,and 1(10%)in the duodenum.A mucosal dimple was noted in 6(60%).Mean lesion size was 17(8-25)mm.Gastrointestinal wall involvement:muscularis mucosae,10%;submucosa,70%;muscularis propria,60%;and serosa,10%.Nine(90%)lesions were hypoechoic and 5(50%)were homogenous.A duct was seen in 5(50%).FNA was attempted in 9(90%)and successful in 8(80%)patients after 4(2-6)passes.Cytology showed acini or ducts in 7 of 8(88%).Superficial biopsies in 7 patients(70%)showed normal gastric mucosa.Deep endoscopic biopsies were taken in 2 patients and diagnostic in one.One patient(10%)developed pancreatitis after EUS-FNA.Two patients(20%)underwent surgery to relieve symptoms or confirm the diagnosis.The main limitation of the study was the fact that it was retrospective and performed at a single medical center.CONCLUSION:EUS features of EP include antral location,mucosal dimple,location in layers 3-4,and lesional duct,and FNA or biopsy is accurate and effective.Augustin Attwell Sharon Sams Norio Fukami 2015World Journal of Gastroenterology2015,21,8:22
6电子治理的演进及持续挑战显示文摘电子治理是指运用信息与通讯技术(ICTs)来支撑公共服务、政府管理、民主程序、并改善公民、公民社会、私有部门与国家之间的关系。经过20余年的技术创新与政策回应,电子治理的发展可以用5个具有内在关联的目标来描述:建立政策框架、提升公共服务、高质量低成本的政府运作、民主程序中的公民参与、行政和体制改革。本文对美国州政府和地方政府电子治理的总结评估表明:在提升公共服务和改善政府运作方面的投资力度最大,进步最明显;政策制定也已在多个方面取得进步,但新的政策议题不断使问题愈趋复杂;进展最小是在提升民主,以及探索电子治理对行政和体制改革的启示这两个方面。在可以预见的未来,以信息通讯技术为手段的电子治理将会继续发展,并为不断的研究与实践提供一个动态的环境。Sharon S.Dawes 郑磊 纪昌秀 2009电子政务2009,,10:21

8IGF-1R as an anti-cancer target—trials and tribulations显示文摘Type I insulin-like growth factor receptor (IGF-1R) has long been recognized for its role in tumorigenesis and growth, but only recently have the tools for targeting the IGF pathway become available. More than 10 IGF/IGF-1R inhibitors have entered clinical trials, and these belong to three main classes: (1) monoclonal antibodies against IGF-1R, (2) monoclonal antibodies against IGF-1R ligands (IGF-1 and IGF- 2), and (3) IGF-1R tyrosine kinase inhibitors. These IGF-1R-targeting agents share common effects on IGF-1R signaling but differ in mechanisms of action, spectrum of target inhibition, and pharmacological features. Clinical activity of IGF-1R inhibitors has been demonstrated with sustained responses in a small number of patients with select tumor types, such as Ewing sarcoma and thymoma. However, many large clinical trials involving patients with adult tumors, including non-small cell lung cancer, breast cancer, and pancreatic cancer, failed to show clinical benefit in the overall patient population. Possible reasons for failure include the complexity of the IGF-1R/insulin receptor system and parallel growth and survival pathways, as well as a lack of patient selection markers. While IGF-1R remains a valid target for selected tumor types, identification of predictive markers and rational combinations will be critical to success in future development.Helen X.

9Hepatorenal syndrome显示文摘Hepatorenal syndrome (HRS) is a 'functional' and reversible form of renal failure that occurs in patients with advanced chronic liver disease. The distinctive hallmark feature of HRS is the intense renal vasoconstriction caused by interactions between systemic and portal hemodynamics. This results in activation of vasoconstrictors and suppression of vasodilators in the renal circulation. Epidemiology, pathophysiology, as well as current and emerging therapies of HRS are discussed in this review.Sharon Turban Paul J Thuluvath Mohamed G Atta 2007World Journal of Gastroenterology2007,13,30:14
10Immune checkpoint inhibitors in clinical trials显示文摘Immunology-based therapy is rapidly developing into an effective treatment option for a surprising range of cancers. We have learned over the last decade that powerful immunologic effector cells may be blocked by inhibitory regulatory pathways controlled by specific molecules often called 'immune checkpoints.' These checkpoints serve to control or turn off the immune response when it is no longer needed to prevent tissue injury and autoimmunity. Cancer cells have learned or evolved to use these mechanisms to evade immune control and elimination. The development of a new therapeutic class of drugs that inhibit these inhibitory pathways has recently emerged as a potent strategy in oncology. Three sets of agents have emerged in clinical trials exploiting this strategy. These agents are antibodybased therapies targeting cytotoxic T-lymphocyte antigen 4(CTLA4), programmed cell death 1(PD-1), and programmed cell death ligand 1(PD-L1). These inhibitors of immune inhibition have demonstrated extensive activity as single agents and in combinations. Clinical responses have been seen in melanoma, renal cell carcinoma, non-small cell lung cancer, and several other tumor types. Despite the autoimmune or inflammatory immune-mediated adverse effects which have been seen, the responses and overall survival benefits exhibited thus far warrant further clinical development.Elad Sharon Howard Streicher Priscila Goncalves Helen X.Chen 2014Chinese Journal of Cancer2014,33,9:14
11Role of farnesoid X receptor and bile acids in alcoholic liver disease显示文摘Alcoholic liver disease(ALD) is one of the major causes of liver morbidity and mortality worldwide. Chronic alcohol consumption leads to development of liver pathogenesis encompassing steatosis, inflammation, fibrosis, cirrhosis, and in extreme cases, hepatocellular carcinoma. Moreover,ALD may also associate with cholestasis. Emerging evidence now suggests that farnesoid X receptor(FXR) and bile acids also play important roles in ALD. In this review, we discuss the effects of alcohol consumption on FXR, bile acids and gut microbiome as well as their impacts on ALD. Moreover, we summarize the findings on FXR, Fox O3a(forkhead box-containing protein class O3a) and PPARα(peroxisome proliferator-activated receptor alpha) in regulation of autophagy-related gene transcription program and liver injury in response to alcohol exposure.Sharon Manley Wenxing Ding 2015Acta Pharmaceutica Sinica B2015,5,2:12

13Genetic and epigenetic changes associated with cholangiocarcinoma:From DNA methylation to microRNAs显示文摘Cholangiocarcinomas are malignant epithelial liver tumors arising from the intra- and extra-hepatic bile ducts. Little is known about the molecular development of this disease, and very few effective treatment options are available. Thus, prognosis is poor. Genetic and epigenetic changes play an integral role in the neoplastic transformation of human cells to their malignant counterparts. This review summarizes some of the more prevalent genetic alterations (by microRNA expression) and epigenetic changes (hypermethylation of specific gene promoters) that are thought to contribute to the carcinogenic process in cholangiocarcinoma.Monique Stutes Steven Tran Sharon DeMorrow 2007World Journal of Gastroenterology2007,13,48:11
14系统综述与网状Meta分析的PRISMA扩展声明显示文摘PRISMA声明旨在提高系统综述和META分析报告的完整性,该声明已经广泛用于指导系统综述和META分析的报告和发表。原始的PRISMA声明是针对两种干预措施比较的传统的系统综述与META分析而制定的,然而,随着多种干预措施比较的系统综述的发展,实施和报告这一类系统综述面临较大挑战。此时,针对网状META分析的PRISMA扩展声明应运而生,旨在提高网状META分析系统综述的报告质量。PRISMA扩展声明是由专家们通过DELPHI调查、面对面讨论和共识大会而最终确立的。PRISMA扩展声明是在原始PRISMA声明的报告清单的基础上经过修改,最终确定了32个条目,每个条目均与网状META分析报告的内容直接相关。本文对网状META分析的PRISMA扩展声明进行了阐述,对报告清单各条目进行了举例说明,并详细说明了在原始PRISMA声明的基础上新增和修改各条目的理由。此外,PRISMA扩展声明强调了在网状META分析的实际操作中需要重点关注的信息。本文的目标读者包括网状META分析的作者与读者,以及期刊杂志的编辑与同行评审。李志霞 杨俊 叶欣 周凌波 杨智荣 孙凤 詹思延 Brian Hutton Georgia Salanti Deborah M.Caldwell Anna Chaimani Christopher H.Schmid Chris Cameron John P.A.Ioannidis Sharon Straus Kristian Thorlund Jeroen P.Jansen Cynthia Mulrow Ferrán Catalá-López Peter C.Gozsche Kay Dickersin Isabelle Boutron Douglas G.Altman David Moher 2016中国循证心血管医学杂志2016,8,6:11
15New advances in molecular mechanisms and emerging therapeutic targets in alcoholic liver diseases显示文摘Alcoholic liver disease is a major health problem in the United States and worldwide. Chronic alcohol consumption can cause steatosis, inflammation, fibrosis, cirrhosis and even liver cancer. Significant progress has been made to understand key events and molecular players for the onset and progression of alcoholic liver disease from both experimental and clinical alcohol studies. No successful treatments are currently available for treating alcoholic liver disease; therefore, development of novel pathophysiological-targeted therapies is urgently needed. This review summarizes the recent progress on animal models used to study alcoholic liver disease and the detrimental factors that contribute to alcoholic liver disease pathogenesis including miRNAs, S-adenosylmethionine, Zinc deficiency, cytosolic lipin-1β, IRF3-mediated apoptosis, RIP3-mediated necrosis and hepcidin. In addition, we summarize emerging adaptive protective effects induced by alcohol to attenuate alcohol-induced liver pathogenesis including FoxO3, IL-22, autophagy and nuclear lipin-1α.Jessica A Williams Sharon Manley Wen-Xing Ding 2014World Journal of Gastroenterology2014,20,36:10
