目的 系统评价卡介菌多糖核酸注射液（BCG-PSN）治疗扁平疣的有效性及安全性。方法 检索中国学术期刊全文数据库（CNKI）、维普中文科技期刊数据库（VIP）、万方数据库（Wanfang Data）、中国生物医学文献数据库（CBM）和英文数据库Science Direcct、PubMed、Web of Science，从建库到2023年5月国内外发表的BCG-PSN治疗扁平疣的临床随机对照试验（RCT），利用Note Express文献管理软件筛选文献，采用数据提取表提取资料并评价其质量，最后采用Rev Man 5.1软件及TSA v0.9软件进行Meta分析。结果 共纳入14项RCTs，包括患者1 258例。Meta分析结果显示：肌肉注射卡介菌多糖核酸治疗扁平疣的痊愈率［RR＝1.62，95% CI（1.41，1.87），P<0.000 01］和有效率［RR＝1.17，95% CI（1.12，1.22），P<0.000 01］均高于对照组，复发率［RR＝0.34，95% CI （0.21，0.56），P<0.000 1］和不良反应发生率［RR＝0.67，95% CI（0.54，0.84），P=0.000 6］均低于对照组。试验序贯分析结果显示，BCG-PSN治疗扁平疣的痊愈率证据安全可靠。结论 肌肉注射BCG-PSN治疗扁平疣有良好的临床疗效，且安全性良好。

Objective To evaluate the efficacy and safety of BCG Polysaccharide Nucleic Acid Injection (BCG-PSN) in the treatment of verruca plana. Methods The databases of CNKI, Wanfang Data, VIP, CBM, PubMed, Web of Science and Science Direct were searched, limited the clinical randomized controlled trials (RCT) of BCG-PSN for the treatment of verruca plana published at home and abroad from the establishment of the database to May 2023. Note Express was used to screen the literature according to the inclusion and row criteria, and data extraction table was used to extract data and evaluate its quality. Finally, the Rev Man 5.1, and TSA v0.9 software was used to Meta-analyze. Results A total of 14 RCTs were included, including 1 258 patients. Meta-analysis results showed that intramuscular injection of BCG-PSN in the treatment of verruca plana showed a higher recovery rate [RR = 1.62, 95%CI (1.41, 1.87), P< 0.000 01] and effective rate [RR = 1.17, 95%CI(1.12, 1.22), P< 0.000 01] than the control group, the intramuscular injection of BCG polysaccharide nucleic acid can also reduce the recurrence rate [RR = 0.34, 95%CI (0.21, 0.56), P< 0.000 1] and the incidence of adverse reactions [RR = 0.67, 95%CI (0.54, 0.84), P= 0.000 6]. The sequential analysis of experiments results showed that the recovery rate of BCG-PSN was reliable. Conclusions The intramuscular injection of BCG BCG-PSN has good efficacy and safety in the treatment of verruca plana, which can provide evidence for future clinical use.
