Objective To evaluate the effectiveness and safety of ramelteon for chronic insomnia in adults. Methods The following databases as CENTRAL, PubMed, EMbase, ISI, CNKI, CBMdisc, VIP and WanFang Data were searched from the date of their establishment to November 2010. The randomized controlled trials (RCTs) meeting the inclusion criteria were included. The data extraction and quality assessment were conducted according to the methods of Cochrane Reviewers’ Handbook recommend by The Cochrane Collaboration, and meta-analysis was performed with RevMan5.0 software. Results A total of 5 RCTs involving 1 772 patients were included. The results of meta-analyses showed that: a) Effectiveness: In the effectiveness, ramelteon was superior to placebo in latency to persistent sleep (MD=18.36, 95%CI 11.55 to 25.18, Plt;0.000 01), total sleep time (MD= –15.47, 95%CI –22.50 to –8.43, Plt;0.000 1), sleep efficiency (MD= –3.39, 95%CI –5.32 to –1.46, P=0.000 6), sleep quality (MD=0.14, 95%CI 0.03 to 0.25, P=0.01) after one week treatment and latency to persistent sleep (MD=13.02, 95%CI 6.01 to 20.03, P=0.000 3) except for wake after sleep onset (MD= –8.79, 95%CI –17.24 to –0.35, P=0.04) after one month treatment. b) Safety: significant differences were only found in the female prolactin (MD=5.50, 95%CI 2.02 to 8.98, P=0.002) and male free testosterone (MD=15.30, 95%CI 0.62 to 29.98, P=0.04) between the two groups, rather than in all the other hormones concentration, rebound insomnia, withdrawal syndrome, next-day residual effects and incidence rate of adverse reactions. Conclusion Ramelteon has marked effects on adults’ chronic insomnia after 1-week treatment, but its effect is not obvious after 1-month treatment. The adverse reactions are mostly the somnolence, rising of male free testosterone and female prolactin concentration.
目的：了解2007年成都地区17家医院间心血管系统药物的使用状况。方法：采用限定日剂量(DDD)的方法，对成都地区2007年17家医院中心血管系统用药的销售金额、用药频度(DDDs)等进行统计分析。结果：2007年成都地区17家医院心血管系统用药总金额为13 753.86万元，占所有药物销售总额的9.05%。在金额排序和用药频度排序前列中，主要包括中药制剂、钙离子拮抗剂等，中药制剂类产品也销售状况良好。结论：中药制剂发挥巨大作用，依从性好、不良反应发生率低、疗效确切的药物已成为临床医师治疗心血管疾病的首选。
Objective To assess the efficacy and safety of glimepiride for type 2 diabetes mellitus (T2DM). Methods We searched the literature from PubMed, Ovid (All EBM Reviews), CNKI, Wanfang, VIP, CBM and other databases. Evaluating the quality of the study according to Cochrane systematic reviews, Meta-analysis was performed for the results of homogeneous studies by The Cochrane Collaboration’s software RevMan 5.0, and the heterogeneous data conducted a descriptive qualitative analysis. Results Six RCTs included in the analysis and Meta-analysis was not performed due to the insufficient data (for the median or standard deviation). Six RCTs are multi-center, randomized, double-blind, placebo-controlled trials. The results showed that glimepiride groups to reduce glycosylated hemoglobin, lower fasting and postprandial blood glucose, postprandial plasma insulin enhance the efficacy were statistically significant differences (Plt;0.05) compared to placebo groups. Four studies informed the impact of fasting plasma insulin (FI) and 3 studies showed that the glimepiride groups improving the fasting plasma insulin (FI) were statistically significant differences (Plt;0.05), but 1 study showed the two groups had no significant difference (Pgt;0.05). All studies showed minor adverse reactions of glimepiride. Conclusion Glimepiride can reduce the glycosylated hemoglobin, lower the fasting and postprandial blood glucose, improve fasting and postprandial plasma insulin for type 2 diabetes patients, and have minor adverse reactions. In a word, glimepiride is an effective and security sulfonylureas drug.
Objective To assess the effectiveness and safety of irbesartan for hypertensive patients with hyperuricaemia. Methods The databases such as The Cochrane Library (Issue 2, 2010), MEDLINE (by the end of April 2010), SCI (by the end of April 2010), CBM (by the end of April 2010) and CNKI (by the end of April 2010) were searched to collected randomized controlled trails (RCTs) on irbesartan for hypertensive combined with hyperuricaemia. Studies were screened according to the inclusion and exclusion criteria; data were extracted; the methodological quality was evaluated; and meta-analyses were conducted by using RevMan 5.0.0 software. Results Nine studies involving 977 patients were included. The results of meta-analyses showed that compared with the control group, irbesartan was superior in decreasing serum uric acid (SUA) (MD=57.12, 95%CI 16.08 to 98.15, P=0.006); it was similar in controlling blood pressure (Systolic pressure: MD= –0.24, 95%CI –2.19 to 1.71, P=0.81; Diastolic pressure: MD=0.46, 95%CI –1.58 to 2.50, P=0.66), and lower in the incidence rate of adverse reaction (RR=0.07, 95%CI 0.02 to 0.24, P=0.000 1). Conclusion The study suggests that irbesartan is effective and safe to control blood pressure and decrease serum uric acid for hypertensive patients with hyperuricaemia. But because all nine included studies are graded C in quality, the conclusion still needs to be further verified by long-term, large scale and high quality studies.

A total of 29 related literatures involving 33 cases, and a related database was established for statistical analysis. Results The main clinical manifestation represented as endocrine system (48.5%), lesion of skin and its appendants (18.2%), allergic reactions (15.2%), digestive system (9.1%), nervous system (6.1%) and so on.
