1肌萎缩性侧索硬化蛋白激活小胶质细胞NLRP3炎性小体显示文摘小胶质细胞NLRP3炎性小体激活正在成为神经退行性变过程中神经炎症的关键因素。诸如β-淀粉样蛋白和α-突触核蛋白之类的致病性蛋白质聚集体触发小胶质NLRP3激活,从而导致半胱天冬酶-1激活和IL-1β的分泌。在小鼠肌萎缩性侧索硬化症(ALS)的SOD1G93A模型中,半胱天冬酶-1和IL-1β均促进疾病进展,提示小胶质NLRP3在该进程中发挥作用。然而先前的研究表明,SOD1G93A小鼠小胶质细胞不表达NLRP3,SOD1G93A蛋白在小胶质细胞中产生独立于NLRP3的IL-1β。本研究论证了使用Nlrp3-GFP基因敲入小鼠,在SOD1G93A小鼠中小胶质细胞表达NLRP3。本研究显示聚集和可溶性SOD1G93A均可激活小鼠原代小胶质细胞中的炎性小体,导致半胱天冬酶-1和IL-1β裂解,ASC斑点形成以及呈剂量和时间依赖性的IL-1β分泌。重要的是,SOD1G93A无法从缺乏Nlrp3的小胶质细胞或者用特异性NLRP3抑制剂MCC950预处理的小胶质细胞中诱导IL-1β分泌,从而证实NLRP3是介导SOD1诱导的小胶质细胞IL-1β分泌的关键炎症小体复合物。在TDP-43Q331K ALS小鼠模型中也观察到小胶质NLRP3上调,TDP-43野生型和突变蛋白亦可以NLRP3依赖性的方式激活小胶质炎性小体。从机制上讲,本研究确定了活性氧簇和ATP的生成是SOD1G93A介导的NLRP3激活所需的关键事件。总之,本研究的数据表明ALS小胶质细胞表达NLRP3,而病理ALS蛋白激活小胶质NLRP3炎性小体。因此,NLRP3抑制可能是阻止小胶质细胞神经炎症和ALS疾病进展的潜在治疗方法。Vandana Deora John D Lee Eduardo AAlbornoz Luke McAlary Cyril J Jagaraj Avril A B Robertson Julie D Atkin Matthew A Cooper Kate Schroder Justin J Yerbury Richard Gordon Trent MWoodruff 杜一星(编译) 2020神经损伤与功能重建2020,15,9:13
2Redox therapeutics in hepatic ischemia reperfusion injury显示文摘Ischemia-reperfusion plays a major role in the injury experienced by the liver during transplantation. Much work has been done recently investigating the role of redox species in hepatic ischemia-reperfusion. As animal models are better characterized and developed, and more insights are gained into the pathophysiology of hepatic ischemia reperfusion injury in humans the questions into exactly how oxidants participate in this injury are becoming more refined. These questions include effects of cellular location, timing of injury, and ability of therapeutics to access this site are increasing our appreciation of the complexity of ischemia reperfusion and improving attempts to ameliorate its effects. In this review, we aim to discuss the various methods to alter redox chemistry during ischemia reperfusion injury and future prospects for preventing organ injury during hepatic ischemia reperfusion.Rakesh P Patel John D Lang Alvin B Smith Jack H Crawford 2014World Journal of Hepatology2014,6,1:9

4Meeting report:a hard look at the state of enamel research显示文摘The Encouraging Novel Amelogenesis Models and Ex vivo cell Lines(ENAMEL) Development workshop was held on 23 June 2017 at the Bethesda headquarters of the National Institute of Dental and Craniofacial Research(NIDCR). Discussion topics included model organisms, stem cells/cell lines, and tissues/3 D cell culture/organoids. Scientists from a number of disciplines,representing institutions from across the United States, gathered to discuss advances in our understanding of enamel, as well as future directions for the field.ophir d klein olivier duverger wendy shaw rodrigo s lacruz derk joester janet moradian-oldak megan k pugach j timothy wright sarah e millar ashok b kulkarni john d bartlett thomas gh diekwisch pamela den besten james p simmer 2017International Journal of Oral Science2017,9,4:3

6Early infant male circumcision:Systematic review,risk-benefit analysis,and progress in policy显示文摘AIM To determine whether recent evidence-based United States polices on male circumcision(MC) apply to comparable Anglophone countries,Australia and New Zealand.METHODS Articles in 2005 through 2015 were retrieved from PubM ed using the keyword 'circumcision' together with 36 relevant subtopics.A further PubM ed search was performed for articles published in 2016.Searches of the EMBASE and Cochrane databases did not yield additional citable articles.Articles were assessed for quality and those rated 2+ and above according to the Scottish Intercollegiate Grading System were studied further.The most relevant andrepresentative of the topic were included.Bibliographies were examined to retrieve further key references.Randomized controlled trials,recent high quality systematic reviews or meta-analyses(level 1++ or 1+ evidence) were prioritized for inclusion.A risk-benefit analysis of articles rated for quality was performed.For efficiency and reliability,recent randomized controlled trials,metaanalyses,high quality systematic reviews and large welldesigned studies were used if available.Internet searches were conducted for other relevant information,including policies and Australian data on claims under Medicare for MC.RESULTS Evidence-based policy statements by the American Academy of Pediatrics(AAP) and the Centers for Disease Control and Prevention(CDC) support infant and later age male circumcision(MC) as a desirable public health measure.Our systematic review of relevant literature over the past decade yielded 140 journal articles that met our inclusion criteria.Together,these showed that early infant MC confers immediate and lifelong benefits by protecting against urinary tract infections having potential adverse long-term renal effects,phimosis that causes difficult and painful erections and 'ballooning' during urination,inflammatory skin conditions,inferior penile hygiene,candidiasis,various sexually transmissible infections in both sexes,genital ulcers,and penile,prostate and cervical cancer.Our risk-benefit analysis showed that benefits exceeded procedural risks,which are predominantly minor,by up to 200 to 1.We estimated that more than 1 in 2 uncircumcised males will experience an adverse foreskin-related medical condition over their lifetime.Wide-ranging evidence from surveys,physiological measurements,and the anatomical location of penile sensory receptors responsible for sexual sensation strongly and consistently suggested that MC has no detrimental effect on sexual function,sensitivity or pleasure.United States studies showed that early infant MC is cost saving.The evidence supporting early infant MC has further strengthened since the positive AAP and CDC reviews.CONCLUSION Affirmative MC policies are needed in Australia and New Zealand.Routine provision of accurate,unbiased education,and access in public hospitals,will maximize health and financial benefits.Brian J Morris Sean E Kennedy Alex D Wodak Adrian Mindel David Golovsky Leslie Schrieber Eugenie R Lumbers David J Handelsman John B Ziegler 2017World Journal of Clinical Pediatrics2017,6,1:2

8Outcomes of submucosal(T1b) esophageal adenocarcinomas removed by endoscopic mucosal resection显示文摘AIM To investigate the outcomes and recurrences of p T1 b esophageal adenocarcinoma(EAC) following endoscopic mucosal resection(EMR) and associated treatments.METHODS Patients undergoing EMR with pathologically confirmed T1 b EAC at two academic referral centers were retrospectively identified.Patients were divided into 4 groups based on treatment following EMR:Endoscopic therapy alone(group A),endoscopic therapy with either chemotherapy,radiation or both(group B),surgicalresection(group C) or no further treatment/lost to follow-up(<12 mo)(group D).Pathology specimens were reviewed by a central pathologist.Follow-up data was obtained from the academic centers,primary care physicians and/or referring physicians.Univariate analysis was performed to identify factors predicting recurrence of EAC.RESULTS Fifty-three patients with T1 b EAC underwent EMR,of which 32(60%) had adequate follow-up ≥ 12 mo(median 34 mo,range 12-103).There were 16 patients in group A,9 in group B,7 in group C and 21 in group D.Median follow-up in groups A to C was 34 mo(range 12-103).Recurrent EAC developed overall in 9 patients(28%) including 6(38%) in group A(median:21 mo,range:6-73),1(11%) in group B(median:30 mo,range:30-30) and 2(29%) in group C(median 21 mo,range:7-35.Six of 9 recurrences were local;of the 6 recurrences,5 were treated with endoscopy alone.No predictors of recurrence of EAC were identified.CONCLUSION Endoscopic therapy of T1 b EAC may be a reasonable strategy for a subset of patients including those either refusing or medically unfit for esophagectomy.Darren D Ballard Neel Choksi Jingmei Lin Eun-Young Choi B Joseph Elmunzer Henry Appelman Douglas K Rex Hala Fatima William Kessler John M DeWitt 2016World Journal of Gastrointestinal Endoscopy2016,8,20:2
