1溃疡性结肠炎显示文摘溃疡性结肠炎(ulcerativecolitis,uc)是一种消化道炎症性疾病,病变主要位于结直肠。UC好发于青年人,发达国家的人群患病率较高。UC表现为结直肠弥漫性、连续性浅表炎症,以及相应的组织学改变。下消化道内镜或影像检查可以明确诊断。目前尚未发现UC的明确病因,其发病机制与遗传易感个体的结肠内环境变化有关,具有慢性、终身、易复发的病程特点。Alexander C Ford Paul Moayyedl Steven B Hanauer Joseph B Kirsner 谭蓓 吴东 2017英国医学杂志中文版2017,20,7:7

5成人突发性耳聋突发性耳聋:是否采用高压氧疗法需要达成共识显示文摘突发性耳聋的自愈率只有39%,其患者需要接受相应的治疗1.Fishman和Cullen所著的突发性耳聋治疗方法的文章中未提及高压氧治疗2。Cochrane系统评价发现高压氧疗法与类固醇疗法相比,疗效更为显著。Cochrane系统评价指出,“由于采用此疗法的患者人数较少,高压氧疗法尚不成熟完善,且相关的文献报道较少,应对其疗效的可靠性持怀疑态度。”J Alexander Ahmed B Bayoumy 李谨(译) 张罗(校) 2019英国医学杂志中文版2019,22,5:4
6Immunohistochemical analysis of the Wnt/β-catenin signaling pathway in pancreatic neuroendocrine neoplasms显示文摘AIM: To investigate the role of the Wnt/β-catenin pathway in pancreatic neuroendocrine neoplasms(PanN ENs). METHODS: Tissue microarrays containing 88 PanN ENs were immunohistochemically labeled with antibodies to β-catenin, E-cadherin, adenomatous polyposis coli(APC), chromogranin and synaptophysin. One case had only metastatic tumors resected, whereas others(n = 87) received pancreatectomy with or without partial hepatectomy. Pathology slides, demographic, clinicopathologic, and follow up data were reviewed. Patients' demographics, clinicopathologic features, and immunohistochemical results from 87 primary tumors were compared between patients with low stage(stage Ⅰ/Ⅱ) and high stage(stage Ⅲ/Ⅳ) tumors. In addition, correlation of immunohistochemical results from primary tumors with disease-specific survival(DSS) was evaluated. RESULTS: Strong membranous β-catenin staining in the primary tumor was observed in all 13 stage Ⅲ/Ⅳ Pan NENs as compared to 47%(35/74) of stage Ⅰ/Ⅱtumors(P < 0.01). However, the strong membranous β-catenin staining was unassociated with tumor grade or DSS. Decreased membranous β-catenin staining was associated with decreased membranous E-cadherin labeling. Nuclear β-catenin staining was seen in 15%(2/13) of stage Ⅲ/Ⅳ Pan NENs as compared to 0%(0/74) of stage Ⅰ/Ⅱ tumors(P = 0.02). The case with metastasectomy only also showed nuclear β-catenin staining. Two of the three cases with nuclear β-catenin staining were familial adenomatous polyposis(FAP) patients. Lack of APC expression was seen in 70%(57/81) of the cases, including the 3 cases with nuclear β-catenin staining. Expression of E-cadherin and APC in primary tumor was not correlated with tumor grade, tumor stage, or disease specific survival. CONCLUSION: The Wnt/β-catenin pathway was altered in some PanN ENs, but did not Impact DSS. PanN ENs in FAP patients demonstrated nuclear β-catenin accumulation and loss of APC.Vivian Weiss Julie Dueber Jesse P Wright Justin Cates Frank Revetta Alexander A Parikh Nipun B Merchant Chanjuan Shi 2016World Journal of Gastrointestinal Oncology2016,8,8:3

8Reduced anoctamin 7(ANO7) expression is a strong and independent predictor of poor prognosis in prostate cancer显示文摘Objective:Anoctamin 7(ANO7)is a calcium2+-dependent chloride ion channel protein.Its expression is restricted to prostate epithelial cells.The exact function is unknown.This study aimed to analyze ANO7 expression and its clinical significance in prostate cancer(PCa).Methods:ANO7 expression was assessed by immunohistochemistry in 17,747 clinical PCa specimens.Results:ANO7 was strongly expressed in normal prostate glandular cells but often less abundant in cancer cells.ANO7 staining was interpretable in 13,594 cancer tissues and considered strong in 34.4%,moderate in 48.7%,weak in 9.3%,and negative in 7.6%.Reduced staining was tightly linked to adverse tumor features[high classical and quantitative Gleason grade,lymph node metastasis,advanced tumor stage,high Ki67 labeling index,positive surgical margin,and early biochemical recurrence(P<0.0001 each)].The univariate Cox hazard ratio for prostate-specific antigen(PSA)recurrence after prostatectomy in patients with negative vs.strong ANO7 expression was 2.98(95%confidence interval 2.61–3.38).The prognostic impact was independent of established pre-or postoperatively available parameters(P<0.0001).Analysis of annotated molecular data showed that low ANO7 expression was linked to TMPRSS2:ERG fusions(P<0.0001),elevated androgen receptor expression(P<0.0001),as well as presence of 9 of 11 chromosomal deletions(P<0.05 each).A particularly strong association of low ANO7 expression with phosphatase and tensin homolog(PTEN)deletion may indicate a functional relationship with the PTEN/AKT pathway.Conclusions:These data identify reduced ANO7 protein expression as a strong and independent predictor of poor prognosis in PCa.ANO7 measurement,either alone or in combination,might provide clinically useful prognostic information in PCa.Andreas Marx Lena Koopmann Doris Hoflmayer Franziska Büscheck Claudia Hube-Magg Stefan Steurer Till Eichenauer Till S.Clauditz Waldemar Wilczak Ronald Simon Guido Sauter Jakob R.Izbicki Hartwig Huland Hans Heinzer Markus Graefen Alexander Haese Thorsten Schlomm Christian Bernreuther Patrick Lebok Sarah Bonk 2021Cancer Biology & Medicine2021,18,1:3

11未来阻燃剂的设计(英文)显示文摘阻燃剂已经存在数千年了,但最近200年才发展出一些新化学结构的阻燃剂。目前使用的阻燃剂主要包括7种类型,它们是卤素基、磷基、膨胀体系、矿物填料、氮基、无机物基、高分子纳米复合体系等。现在,阻燃剂的使用仅仅专注于提供消防,也没有考虑如何延长它们的使用寿命,没有考虑如何处理阻燃剂使用结束后的后处理问题。随着将来对环境保护新要求的提升,以及新型起火原因的出现,现有的几类阻燃剂显然是不够的,必须努力开发新型阻燃剂,例如硅基阻燃剂、过度金属催化作用阻燃剂等。讨论了未来阻燃剂的设计必须考虑的环境保护和新的起火原因等问题,以及与未来新型阻燃剂有关的潜在化学问题。最后提出了在新型阻燃剂研究过程中,减少环境污染、保持防火安全的原则。Alexander B Morgan 2013中国材料进展2013,32,3:2
