中草药治疗子宫内膜异位症的系统评价

目的系统评价中草药治疗子宫内膜异位症的临床疗效和安全性.方法计算机检索Cochrane Library,MEDLINE,EMBASE,中国生物医学文献数据库(从数据库建立至2003年),纳入以子宫内膜异位症患者为研究对象的随机或半随机对照试验,对纳入研究的方法学质量(包括随机方法,盲法,分配隐藏及失访)进行评价.用RevMan 4.3软件进行统计分析.结果共纳入10个包括1 120例患者的随机或半随机对照试验.因各研究采用不同的中药或对照,故仅能进行单个描述和重新计算各研究的疗效效应量.多数研究显示,口服中药对总有效率、提高妊娠率及痛经缓解率的疗效与丹那唑、三苯氧胺等西药相当;个别研究显示中药优于西药;对异位囊肿体积缩小的效果尚不能肯定;仅1个研究报道了采用中药灌肠治疗内异症的复发率低于口服三苯氧胺[RR 0.20, 95%CI (0.05, 0.70)];5篇研究报道了对副作用的观察,中药的副作用少于西药.结论中药可有效治疗子宫内膜异位症,且副作用少于西药,但由于纳入研究数量少且质量不高,因此其论证强度较弱,尚需更多高质量研究以增加论证强度.

Efficacy and Safety of Chinese Medicinal Herbs for Endometriosis:A Systematic Review

Objective To assess the efficacy and safety of Chinese medicinal herbs for treating endometriosis. Methods We searched Cochrane Library, MEDLINE, EMBASE, CBM (from establishment to 2003). Randomized controlled trials (RCTs) and quasi-randomized controlled trials of patients with endometriosis were included. The quality of included studies such as randomization, blinding, allocation concealment and loss of follow up were evaluated and meta-analysis was performed by RevMan 4.3 software. Results Ten RCTs or quasi-RCTs involving 1 120 patients were included. Because of different therapies in the treatment and control groups, the results of outcome were described separately.Most of included studies suggested that the effects of traditional Chinese medicine (TCM) on general effect, pregnancy rate improvement and alleviating dysmenorrhoea were similar to Danazol or Tamoxifen, only a few studies showed better effects. There was no evidence to support that TCM was more effective than western medicine in reducing the size of endometriotic cysts. Only one study mentioned the recurrence rate and showed that TCM enema had lower recurrence rate than oral Tamoxifen with OR 0.17, 95%CI 0.04 to 0.67.Five studies mentioned adverse reactions and showed TCM had fewer adverse effects than western medicine. Conclusion Chinese medicinal herbs are effective in treating endometriosis with fewer adverse effects. The evidence is not strong enough because of low quality of the included studies. Therefore, more high quality randomized controlled trials are required.
