1抗炎介质表达缺陷参与中性粒细胞型支气管哮喘发病机制:半乳糖凝集素-3和白细胞介素-1RA/白细胞介素-1beta比例显著下降显示文摘支气管哮喘(哮喘)是具有异质性的气道炎症性疾病,其主要特点表现为气道高反应和可变的气流受限。在哮喘的发病机制中,过敏原诱导的TH2淋巴细胞激活以及IL-5介导的嗜酸粒细胞渗出起到重要的作用。近年来发现超过50%的哮喘患者气道的嗜酸粒细胞水平并不增高,并将这种亚型定义为非嗜酸粒细胞型哮喘。其中部分患者表现为气道中性粒细胞明显增高,称为中性粒细胞型哮喘。高鹏 Peter G Gibson Katherine J Baines Ian A Yang John W Upham Paul N Reynolds Sandra Hodge Alan L James Christine Jenkins Matthew J Peters 张捷 Jodie L Simpson 2016中华结核和呼吸杂志2016,39,11:5
2新加坡成人慢性呼吸系统疾病患者6分钟步行距离的最小临床重要差异值研究(英文)显示文摘目的:6 min步行距离(6MWD)是临床上常见的功能性运动能力测试,特别是对于慢性呼吸系统疾病患者。一些文献记载了关于白种人的6MWD的最小临床重要差异(MCID),但对亚洲人群的相关信息未见记载。本研究旨在建立亚洲成人慢性呼吸道疾病患者6MWD的最小临床重要差异。方法:采用'锚定'法和'分布'法对新加坡中央医院肺康复计划登记处的资料进行了分析。'锚定'法收集确诊为慢性呼吸道疾病的患者50例,其中男38例,女12例;平均年龄(64.2±12.3)岁,通过电话采访及使用整体变化评估量表(GROC)评价患者肺康复计划后的自觉改善程度,再将患者在肺康复计划中6MWD的改变数值与相对应的患者自觉改善程度进行比较,这种关系用操作特征曲线(ROC)统计表示。通过'分布'法确定6MWD的MCID,从门诊和住院的肺康复计划(PRP)参与者中检索医疗记录136例,其中男103例,女33例;平均年龄(60.1±14.1)岁。结果 :ROC曲线表明6MWD出现临床显著性变化的最佳临界值为17.4 m,其对应的敏感性为79.4%,特异性为81.3%,阳性似然比为4.23。由'分布'法确定6MWD的最小临床重要差异值为18.6 m。结论:18.6 m为新加坡华人6MWD的最小临床重要差异的估计值。Meredith T L YEUNG Alan W P WONG Katherine S L HUANG Alice Y M JONES 2015康复学报2015,25,1:3

4Diagnostic accuracy of tests for Helicobacter pylori in an Alaska Native population显示文摘AIM:To evaluate the accuracy of two non-invasivetests in a population of Alaska Native persons. Highrates of Helico bacter pylori(H. pylori) infection,H. pylori treatment failure,and gastric cancer in this population necessitate documentation of infection status atmultiple time points over a patient's life.METHODS:In 280 patients undergoing endoscopy,H. pylori was diagnosed by culture,histology,rapidurease test,13C urea breath test(UBT) ,and immuno-globulin G antibodies to H. pylori in serum. The performances of 13C-UBT and antibody test were compared to a gold standard defined by a positive H. pylori testby culture or,in case of a negative culture result,bypositive histology and a positive rapid urease test.RESULTS:The sensitivity and specificity of the 13C-UBT were 93% and 88%,respectively,relative to thegold standard. The antibody test had an equivalents ensitivity of 93% with a reduced specificity of 68%.The false positive results for the antibody test were as-sociated with previous treatment for an H. pylori infection [relative risk(RR) = 2.8]. High levels of antibodiesto H. pylori were associated with chronic gastritis and male gender,while high scores in the 13C-UBT testwere associated with older age and with the H. pyloribacteria load on histological examination(RR = 4.4) .CONCLUSION:The 13C-UBT out performed the anti-body test for H. pylori and could be used when a non-invasive test is clinically necessary to document treatment out come or when monitoring for reinfection.Dana L Bruden Michael G Bruce Karen M Miernyk Julie Morris Debby Hurlburt Thomas W Hennessy Helen Peters Frank Sacco Alan J Parkinson Brian J McMahon 2011World Journal of Gastroenterology2011,17,42:3
5Listeria monocytogenes following orthotopic liver transplantation:Central nervous system involvement and review of the literature显示文摘Listeria monocytogene is a well-recognized cause of bacteremia in immunocompromised individuals,including solid organ transplant recipients,but has been rarely reported following orthotopic liver transplantation. We describe a case of listeria meningitis that occurred within a week after liver transplantation. The patient developed a severe headache that mimicked tacrolimus encephalopathy,and was subsequently diagnosed with listeria meningitis by cerebrospinal fluid culture. The infection was successfully treated with three-week course of intravenous ampicillin. Recurrent hepatitis C followed and was successfully treated with interferon alfa and ribavirin. Fourteen cases of listeriosis after orthotopic liver transplantation have been reported in the English literature. Most reported cases were successfully treated with intravenous ampicillin. There were four cases of listeria meningitis,and the mortality of them was 50%. Early detection and treatment of listeria meningitis are the key to obtaining a better prognosis.Shugo Mizuno Ivan R Zendejas Alan I Reed Robin D Kim Richard J Howard Alan W Hemming Denise C Schain Consuelo Soldevila-Pico Roberto J Firpi Shiro Fujita 2007World Journal of Gastroenterology2007,13,32:2
6应对全球气候变化:全科医生的临床经验和方法显示文摘背景气候变化是全球公共卫生问题,需要全面深入的思考才能获得行之有效的解决方法。本文从理论上阐述全科医生临床经验和方法对于解决气候变化问题的借鉴意义。讨论我们认为全科医生的经验和特殊思考方式对解决气候变化问题是一笔宝贵的财富。这些财富包括,毕生对'首先不造成伤害'和'处理不确定性'的认知、反思和践行,'面对不完整信息时做出必要决策'的能力,对'复杂自适应系统'的认识,对稳态的维持,对意外后果的警醒,对'跨学科和跨专业'重要性的认识。总结全科医生一直以来都是公共卫生的拥护者。他们对复杂人类问题的处理方式也可用于应对气候变化。Grant Blashki Alan Abelsohn Robert Woollard Neil Arya Margot W Parkes Paul Kendal Erica Bell R Warren Bell 邵钧 2013中国全科医学2013,16,10:2

9两种对比度近阅读视力卡的研制和应用显示文摘目的介绍对比敏感度近阅读视力卡的设计原理及使用方法。方法按对数级数设计的视标进行视力检查,用100%和10%对比度的视力卡来检查对比敏感度。结果和结论通过视力卡检查可评价视力损害程度,并预测在用高度数眼镜或放大镜纠正以及更好地控制眩光和照明的情况下视功能的改善情况。对比敏感度文字阅读测试能快速检测出高对比度视力接近正常的患者有可能同时存在低对比度视力的损害,提示是否需要进行白内障手术或其他治疗。Alan W Johnston 于旭东 唐甜甜 祝莲 姜俭 2005眼视光学杂志2005,7,4:2
