【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.

Methods The cases of ADRs caused by fenofibrate were collected and analyzed from Pubmed (1978 - August 2009), CNKI (1980 - August 2009) and CBMDise (1980 - August 2009). Results Fenofibrate-induced ADRs were mostly seen in patients over 40 years old, but which was independent for sex. Totally, 64 ADRs were involved in the skeletal musculature system, digestive system, urinogenital system, and allergic response. The prognosis was favorable. Conclusion More attention should be given to patients with fenofibrate and ADRs should be treated as soon as possibile.
Objective To assess the effectiveness and safety of Tongxinluo Capsule in the treatment of vertebrobasilar artery insufficiency. Methods The Cochrane Library, MEDLINE, VIP and CNKI were searched. Two authors independently collected data, including randomized controlled trials that met the inclusion criteria. They evaluated the quality of these trials and performed meta-analysis using The Cochrane Collaboration’s RevMan 5.0. Results Eleven studies involving 1157 participants were included. All the included studies were inadequate at reporting randomization, concealment of allocation and blinding. Meta-analysis based on the included studies showed that Tongxinluo Capsule with Danshen was better than Danshen alone in vertebrobasilar artery insufficiency (RR= 1.35, 95%CI 1.24 to 1.48) and blood flow velocity of vertebrobasilar artery (WMD=3.60, 95%CI 2.44 to 4.77 and WMD=3.46, 95%CI 1.89 to 5.04). Tongxinluo Capsule with simple basic therapy was better than simple basic therapy alone in vertebrobasilar artery insufficiency (RR=1.21, 95%CI 1.11 to 1.31) and blood flow velocity of vertebrobasilar artery (WMD=3.85, 95%CI 2.19 to 5.51). Conclusion Tongxinluo Capsule is an effective and safe drug for vertebrobasilar artery insufficiency. However, due to the limited quantity and quality of the included studies, we can not draw a firm conclusion about the effectiveness of Tongxinluo Capsule compared to the simple basic therapy or Danshen. The results suggest that further and larger-scale trials using Tongxinluo Capsule for vertebrobasilar artery insufficiency are needed.
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.

目的 評價卡培他濱+伊立替康與氟尿嘧啶/醛氫葉酸（5-FU/LV）+伊立替康治療轉移性結直腸癌的有效性和安全性。 方法 計算機檢索PubMed、CENTRAL、Embase、中國生物醫學數據庫、中國期刊全文數據庫、維普數據庫和萬方數據庫，檢索時間均從建庫至2011年9月。對符合納入標準的隨機對照試驗進行質量評價和Meta分析。 結果 納入3個隨機對照試驗，共計419例患者，卡培他濱+伊立替康在中位生存期、完全緩解率[RR=1.58，95%CI（0.27，9.11），P=0.61]、部分緩解率[RR=0.86，95%CI（0.68，1.09），P=0.20]、總有效率[RR=0.88，95%CI（0.71，1.09），P=0.26]上表現出與5-FU/LV+伊立替康相似的效果，安全性方面卡培他濱+伊立替康有較高的Ⅲ/Ⅳ級惡心[RR=1.92，95%CI（1.05，3.54），P=0.04]、腹瀉[RR=3.23，95%CI（2.14，4.89），P＜0.000 01]發生風險和較低的Ⅲ/Ⅳ級中性粒細胞減少[RR=0.72，95%CI（0.53，0.98），P=0.04]發生風險。 結論 根據當前現有證據，5-FU/LV+伊立替康可能較卡培他濱+伊立替康更為有利于轉移性結直腸癌患者的治療，但仍需結合臨床實際情況進行化療方案的優選。
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 evaluate the efficacy and safety of vildagliptin vs. placebo for patients with type 2 diabetes.Methods The following databases as The Cochrane Library (Issue 2, 2010), PubMed (1978 to September, 2010), EMbase (1974 to September, 2010), CNKI (1978 to September, 2010), VIP (1989 to September, 2010) and CBM (1978 to September, 2010) were searched to collect the randomized controlled trials (RCTs) of vildagliptin vs. placebo in treating type 2 diabetes. Two reviewers screened the trials according to the inclusion and exclusion criteria, extracted the data, assessed the quality in accordance with the Cochrane Collaboration, and conducted meta-analyses with RevMan 5.0 software. Results A total of 13 studies were included. The results of meta-analyses showed that the vildagliptin given as monotherapy led to greater reduction in HbA1c compared with the placebo (MD= –0.76, 95%CI –0.94 to –0.58, Plt;0.000 01), but it was inferior to the placebo in losing weight (MD=0.68, 95%CI 0.29 to 1.07, P=0.000 6). When the vildagliptin was given as monotherapy, there was no statistical difference in the incidence of overall adverse events (AEs) (OR=1.00, 95%CI 0.83 to 1.21, P=0.98) and hypoglycaemia (OR=1.03, 95%CI 0.65 to 1.65, P=0.89). When the vildagliptin was combined with other oral antihyperglycemic drugs or insulin, it produced greater reduction in level of HbA1c (MD= –0.76, 95%CI –0.94 to –0.58, Plt;0.000 01), and there was no statistically significant difference between vildagliptin and placebo in weight loss (MD=0.40, 95%CI –0.25 to 1.05, P=0.23), AEs (OR=0.95, 95%CI 0.76 to 1.18, P=0.62) and hypoglycaemia (OR=1.11, 95%CI 0.49 to 2.53, P=0.80). Conclusion The vildagliptin treatment for type 2 diabetes is effective and safe. A long-term study in large scale with high quality is required to confirm its long-term outcomes.
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.
