Is short-term therapy really sufficient to eradicate Helicobacter pylori infection?

Objective:The aim of our study was to perform a systematic review and meta-analysis of the efficacy of short-term protocols for Helicobacter pylori eradication and to review the safety and adverse profiles of these eradication protocols.Methods:Literatures were located through electronic searches by PubMed,Medline,ISI Web of Knowledge,and Cochrane Library using the relevant terms.Abstracts of important meetings were searched manually in some journal supplements.Additional bibliographies were identified from the reference lists of identified studies.Three independent reviewers systemically identified randomized controlled trials(RCTs) comparing short-duration protocols vs.7-d proton pump inhibitor(PPI)-based triple protocols,as well as studies reporting eradication rates of short-duration protocols for H.pylori.Summary effect size was calculated as relative risk(RR) and 95% confidence intervals(CI) using Review Manager 4.2,and P0.05 was defined as statistically significant in all analyses.Results:Among 90 abstracts retrieved,15 studies were analyzed,including a total of 30 treatment regimens with 1856 subjects.Mean intention-to-treat(ITT) cure rates of 63.2% and 81.3% were achieved with short-term protocols and 7-d PPI-containing protocols,respectively.Per-protocol(PP)-based overall cure rates were 66.6% and 86.1%,respectively.Short-term therapy was inferior to 7-d triple regimen(P0.00001).After sub-analysis,however,comparing the effects of ≥3-d protocols and 7-d triple protocols,the cumulative ITT RR was 0.95(P=0.26),and PP RR was 0.95(P=0.10),without significant heterogeneity.Moreover,slightly fewer adverse-effects were found in short-term protocols.Conclusions:Although more economical,short-duration protocols are inferior to 7-d PPI-based triple protocols with regarding to eradication rate of H.pylori.Protocols of more than 3 d,however,may be equivalent to 7-d protocols.     

An intelligent electronic capsule system for automated detection of gastrointestinal bleeding

In clinical practice, examination of the hemorrhagic spot (HS) remains difficult. In this paper, we describe a remote controlled capsule (RCC) micro-system with an automated, color-based sensor to identify and localize the HS of the gastrointestinal (GI) tract. In vitro testing of the detecting sensor demonstrated that it was capable of discriminating mimetic intestinal fluid (MIF) with and without the hemoglobin (Hb) when the concentration of Hb in MIF was above 0.05 g/ml. Therefore, this RCC system is able to detect the relatively accurate location of the HS in the GI tract.     

化学学科能力的基本理论问题研究

我国《化学教学大纲》、《化学课程标准》、高考化学《考试大纲(大纲版)》、《考试大纲(课标版)》分别提出了不同内涵的化学学科能力要求,其原因在于,化学学科能力理论的建构缺乏明确的理论基础。为此,我们构建了智力—知识—技能—科学方法能力理论,提出了化学学科的核心能力——观察与实验能力、化学学习能力、化学思维能力、科学探究能力、实践与创新能力,并界定了其能力结构要素。这一能力观对于改变课程改革中能力内涵模糊、能力要求弱化的现状具有非常重要的现实意义。
