Objective To evaluate the efficacy and safety of low-dose versus standard-dose cyclosporine immunosuppressive therapy in kidney transplant recipients. Methods We searched MEDLINE, EMbase, SCI, CBM and The Cochrane Library from the establishment to December 2009 to screen randomized controlled trials (RCTs) of low-dose versus standard-dose cyclosporine immunosuppressive therapy in kidney transplant recipients. Quality assessment and meta-analyses were performed for the included studies. Results A total of 6 RCTs involving 1551 patients were identified, among which 4 RCTs were graded A and two were graded B. The meta-analyses indicated that there were no significant differences between the two groups at the end of 6-month and 12-month follow-up in the acute rejection rate at a RR 1.07, 95%CI 0.69 to 1.65 and a RR 1.06, 95%CI 0.71 to 1.57, respectively. There were no significant differences between the two groups at the end of 6-month and 12-month follow-up in the patients’ death rate at a RR 0.64, 95%CI 0.20 to 2.03 and a RR 0.61, 95%CI 0.30 to 1.24, respectively. There were no significant differences between the two groups in renal function and safety. Conclusion Based on the current evidence, compared with standard-dose CsA, low-dose CsA has the same effect and safety for the short-term results, but the long-term results need to be further studied.
Objective To assess the effectiveness of exemestane in the treatment of postmenopausal women with breast cancer. Methods We searched The Cochrane Library, PubMed, CBMdisc, and CNKI to identify randomized controlled trials (RCTs) that met the inclusion and exclusion criteria. Two reviewers extracted the data and evaluated the quality of included trials, respectively. Meta-analysis was performed using RevMan 5.0 software. Results A total of 12 RCTs involving 6 166 participants were included, and the results of meta-analyses showed that: (1) When used in neoadjuvant endocrine therapy after operation, exemestane was more effective in progression-free survival than tamoxifen; (2) When used in rescue therapy, exemestane was more effective in objective response than tamoxifen, but not more effective than letrozole or anastrozole; (3) When used in new neoadjuvant endocrine therapy before operation, exemestane was not more effective than letrozole, and there was too little research about it. Conclusions The current evidence shows that exemestane has certain short-term therapeutic effect, but its long-term therapeutic effect is unknown. More high-quality clinical trials are expected for further study.
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.
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.
【摘要】 目的 采用循證醫學的方法評價硫唑嘌呤（aiathioprine，AZA）治療潰瘍性結腸炎（ulcerative colitis，UC）的有效性和安全性。 方法 計算機檢索PubMed、Cochrane library、Embase、CNKI、維普和CBM數據庫收集國內外關于AZA診療UC的隨機對照試驗（ramdomized controllel trial，RCT）。按Cochrane系統評價的方法評價納入研究質量，并進行Meta分析。 結果 共納入5個RCT，共262例UC患者。Meta分析結果顯示，AZA治療UC在緩解率方面與安慰劑比較，差異無統計學意義[P=1.19，95%CI（0.94，1.49），P=0.14]；在復發率方面，兩者比較差異有統計學意義[P=0.72，95%CI（0.54，0.95），P=0.02]；全部不良反應方面和嚴重不良反應方面，兩者比較差異無統計學意義，Meta分析結果分別為[P=2.52，95%CI（0.82，7.74），P=0.11]和[P=4.03，95%CI（0.88，18.53），P=0.07]。 結論 系統評價結果為AZA在療效方面優于安慰劑，在不良反應發生率方面差異無統計學意義。但由于納入的5個研究中沒有高質量的RCT，且有1個可能產生高度偏倚，使得這一結論受到影響，有必要開展更多設計嚴謹，大樣本、多中心的RCT。【Abstract】 Objective To assess the efficacy and safety of azathio-prine in the treatment of ulcerative colitis through an evidence-based method. Methods We searched the literature from databases like PubMed, Cochrane library, CNKI, VIP, and CBM, and evaluated the quality of studies according to Cochrane systematic review. Finally, Meta-analysis was performed. Results Five randomized controlled trials (RCT) were included in this study with a total of 262 patients. Meta-analysis showed that there was no significant difference in the rate of remission between azathio-prine and placebo in treating ulcerative colitis [P=1.19, 95%CI (0.94, 1.49),P=0.14]. There was significant difference in the relapse rate between the two treating methods [P=0.72, 95%CI (0.54, 0.95),P=0.02]. In addition, there was no statistical difference in all adverse effects [P=2.52, 95%CI (0.82, 7.74),P=0.11] and serious adverse effects [P=4.03, 95%CI (0.88, 18.53),P=0.07] between the two treating methods. Conclusion In the treatment of ulcerative colitis, azathio-prine has a significant advantage in efficacy than placebo, but there is no significant difference in the rate of adverse events between the two groups. However, none of the 5 RCT included in this review has a high quality and one of them even probably has a high bias, which has a big influence on our conclusion. Consequently, multi-center large-scale randomized controlled trials of higher quality are needed to make confirmation.
Objective To review the efficacy and safety of Kushenin combined with Adefovir Dipivoxil for Chronic Hepatitis B (CHB). Method Randomized controlled trails of Kushenin combined with Adefovir Dipivoxil for CHB were gathered from PubMed, CBMdisc (1978 to 2009), and CSJD (1989 to 2009), while other relative researches were searched manually; every research was evaluated, and then analyzed with RevMan 5.0.0 software. Result Ten randomized controlled trials were included; among total 855 patients, 436 were in trial group and the other 419 were in control group. As the Meta-analysis showed, the therapeutic effect of kushenin combined with Adefovir Dipivoxil was better than that of Adefovir Dipivoxil in aspects of improving the negative rate of serum ALT (RR=1.28, 95%CI 1.17 to 1.40), the negative rate of serum HBV-DNA (RR=1.27, 95%CI 1.13 to 1.42), the negative rate of serum HBeAg (RR=1.80, 95%CI 1.32 to 2.44), and the conversion rate of HBeAg and anti-HBe (RR2.06, 95%CI 1.43 to 2.95). Conclusion Kushenin combined with Adefovir Dipivoxil in treating CHB can improve the conversion rate of HBeAg and anti-HBe and further take better therapeutic effect.

Methods Literatures were retrieved from PubMed (1978-October, 2010), EMBASE (1974-October 2010), Cochrane library (2nd volume, 2010), China Academic Journal Network Publishing Database (1978-October, 2010), VIP (1989-October, 2010) and CBM (1978 to October, 2010) by computer, and searched some other relevant journals manually. Chinese and English were both used in the search. Randomized controlled trials (RCTs) on sparfloxacin versus ofloxacin in treating pulmonary tuberculosis were included in this study. Meta-analysis was conducted by RevMan 5.0 software. Results The meta-analysis of 8 included RCTs showed that the sputum negative conversion rate, focus absorption rate, cavity closure rate in the sparfloxacin group were significantly higher than the ofloxacin group (P＜0.05). Conclusions The analysis indicates that combined treatment with sparfloxacin has a better effect in treating MDR-TB than with ofloxacin. However, the reliability of this review may be affected by the number and quality of studies included. Large-scale randomized controlled trials of high quality are needed to confirm the conclusions above.
