目的 探讨甲硝唑联合唯阴康治疗细菌性阴道病（BV）的临床疗效。方法 将150例BV患者随机分为两组，单纯口服甲硝唑组（对照组）75例，甲硝唑联合唯阴康用药组（治疗组）75例，用药7 d,观察治疗后两组的有效率及复发率。结果 两组患者停药后第7天的有效率比较无统计学差异，停药后第30天有效率治疗组明显高于对照组（P＜0.05），治疗组复发率明显低于对照组（P＜0.05）。结论 甲硝唑联合唯阴康治疗BV疗效好，优于单纯甲硝唑对照组，复发率低，且未见不良反应，值得临床推广。

Objective To explore the clinical efficacy of co-using Metronidazole and Weiyinkang in treatment of bacterial vaginitis (BV). Methods Cases 150 diagnosed as BV definitely were divided into control group (treated with Metronidazole) (n=75) and treatment group (treated with Metronidazole and Weiyinkang) (n=75), they used for 7 days then the effective rates and relapse rates of the two groups were observed after treatment. Results There was no significant difference in effective rate between the two groups after withdrawal of day 7, but the effective rate of treatment group was significantly higher than that of control group (P＜0.05) after withdrawal of day 30; the relapse rate of treatment group was significantly lower than that of control group (P＜0.05). Conclusion Metronidazole and Weiyinkang are effective in treatment of BV with low relapse rate and no adverse reaction, which is worth of spreading in clinic.
