目的 了解“5.12”汶川地震后四川省安县18个乡镇卫生院的卫生人力资源现状，分析存在的问题并提出建议。 方法 2010年11月采用问卷调查方式对安县18个乡镇卫生所进行调查，收集至2009年12月底卫生人力资源情况进行收集，并就调查结果进行分析。 结果 截至2009年12月底，该县医务人员总数为1 249人，其中乡镇卫生所550人，县级医院699人。在乡镇卫生所中，医生272人，护士116人，医护比为2.34︰1；学历以大专、高中及中专为主; 职称以初级及士级为主。 结论 安县卫生服务技术人员学历、职称、专业结构不尽合理，高层次人才短缺的问题，建议完善相关制度及加强全科医生培养工作。
ObjectiveTo systematically review the clinical efficacy of low-dose erythromycin in patients with stable chronic obstructive pulmonary disease (COPD). MethodsRandomized controlled trials (RCTs) about low-dose erythromycin plus routine treatment versus routine treatment/placebo plus routine treatment in treating stable COPD was electronically searched in PubMed, EMbase, CBM, The Cochrane Library (Issue 4, 2013), CNKI, VIP and WanFang Data from the their establishment dates to May 2013. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed methodological quality. The results of meta-analysis was performed using RevMan 5.2 software. ResultsA total of eight RCTs involving 526 patients were finally included. The results of metaanalysis showed that:a) compared with the control group, low-dose erythromycin significantly improved six-minute walk distance (SMD=0.30, 95%CI 0.05 to 0.55, P=0.02), reduced the frequency of acute exacerbation (RR=0.44, 95%CI 0.25 to 0.78, P=0.005), and decreased the concentrations of IL-8 (SMD=-1.63, 95%CI-2.17 to-1.09, P < 0.000 01), TNF-α (SMD=-1.49, 95%CI-2.36 to-0.62, P=0.000 8), and neutrophil elastase (NE) (SMD=-0.94, 95%CI-1.36 to-0.51, P < 0.000 1) in sputum. b) the erythromycin therapy could improve forced expiratory volume in one second (FEV1) (SMD=0.19, 95%CI-0.19 to 0.58, P=0.32) but without significant differences compared with the control group. ConclusionLow-dose erythromycin could improve exercise tolerance, reduce the frequency of acute exacerbation, and help relieve airway inflammation, but in the improvement of FEV1, low-dose erythromycin is not better than routine treatment. Due to limited quantity and quality of the included studies, larger scale, multicenter, high quality RCTs are needed to verify the aforementioned conclusion.
