简介:目的通过对阿维A酸治疗银屑病的随机对照试验研究进行系统评价,了解阿维A酸治疗银屑病的有效性。方法将观察应用阿维A酸治疗银屑病患者疗效的随机或半随机对照试验进行分析,将有效率作为观察指标。检索中英文文献应用Medline、Pubmed(1966—2004)、Ovid、TheCochranelibrary2004.妒、中国生物医学文献数据库(1978—2004)、Vip全文数据库(1994-2004)、解放军医学图书馆、国家科技图书文献中心的数据库进行电子检索结合手工检索国内的期刊杂志和药厂提供的资料。应用Jadad量表的质量标准进行文献评价,RevMan4.2版软件进行统计分析。用比值比(D曰)和95%CI为疗效分析统计量。采用SPSS和SAS软件制作漏斗图分析潜在的发表偏倚。结果有4个阿维A酸治疗银屑病研究的有效率的按亚组分类后,组间无异质(X^2=1.40,P=-0.71,/2=0%),用固定效应模型进行合并,结果显示应用治疗阿维A酸治疗银屑病的有效率与对照组差异有统计学意义[OR5.93,95%CI(2.79,12.57)]。结论阿维A酸治疗银屑病是有效的,其安全性还需进一步评价,今后随着高质量的报告出现,可以不断的完善本评价。
简介:目的:观察中药浸泡联合阿维A口服治疗跖疣的临床疗效.方法:135例患者随机分为A、B、C三组,A组予中药浸泡治疗,B组予阿维A胶囊口服治疗,C组予中药联合阿维A治疗,共治疗12周.观察三组跖疣消退的情况,并对痊愈的患者随访3个月,观察其复发情况.结果:A组有效率69.8%,B组有效率68.3%,C组有效率88.1%.A组与B组有效率比较,差异无统计学意义,A组和C组、B组和C组有效率比较差异有统计学意义.A组复发率36.4%,B组复发率36.8%,C组复发率8%,A组与B组复发率比较,差异无统计学意义,A组和C组、B组和C组复发率比较差异有统计学意义.结论:中药浸泡联合阿维A口服治疗多发性跖疣疗效好,且复发率低.
