国内外针刺治疗神经性耳鸣临床研究Meta分析

摘要

Objective To conduct a systematic review with evidence collected from randomized controlled trials (RCTs) of domestic and overseas acupuncture for nervous tinnitus. Methods RCTs were searched in several databases i.e. CNKI, VIP, CBM and PubMed, using the keywords of acupuncture and tinnitus. The efficacy and methodologies were evaluated using meta-analysis by RevMan5.0. Efficacy indexes i.e. recovery rate, significant efficiency rate, total effective rate of acupuncture in treating nervous tinnitus were assessed using odds ratio (OR). Funnel plot was drawn to analyze publication bias. Begg’s rank test and Egger’s linear regression test were conducted to measure symmetry in funnel plot by using Stata 11.0. Results Fifteen RCTs involving 1082 patients met the inclusive criteria. The results of meta-analyses showed that recovery rate (OR=2.82, 95%CI 1.89 to 4.20), significant efficiency rate (OR=1.75, 95%CI 1.26 to 2.44), total effective rate (OR=3.68, 95%CI 2.62 to 5.16) were significantly higher in acupuncture group than control group. Begg’s rank test (P=0.350) and Egger’s linear regression test (P=0.887) showed partly symmetry in funnel plot with unfilled corner, which indicated that some degree of bias existed in the included studies. Conclusion According to the analysis results, acupuncture or acupuncture combining other therapies were superior to pure medication or non-acupuncture treatments. However, high-quality, large-sample, randomized, controlled trials seem to be needed to further confirm the efficacy of acupuncture, owing to the different standards and research methods, limited qualities of the included studies.%目的：系统评价针刺治疗神经性耳鸣的有效性。方法以针刺并含耳鸣为主题词检索中国期刊全文数据库、中文科技期刊数据库、中国生物医学数据库和PubMed等数据库有关针刺治疗耳鸣的相关文献,并进行疗效和方法学评价。采用RevMan5.0软件进行Meta分析,合并比值比(OR)评价针刺治疗神经性耳鸣的痊愈率、显效率、总有效率。用漏斗图分析发表偏倚,并采用Stata11.0软件进行Begg秩相关检验及Egger线性回归法判断漏斗图是否对称。结果15篇文献1082例患者符合纳入标准,Meta 分析结果显示,痊愈率合并 OR 值为2.82,95%可信区间(CI)为[1.89,4.20]；显效率合并OR值为1.75,95%CI为[1.26,2.44]；总有效率合并OR值为3.68,95%CI为[2.62,5.16],针刺疗效显著优于对照组。Begg秩相关检验所得P＝0.350,Egger线性回归法所得P＝0.887,漏斗图大体对称,但仍有缺角,文献存在一定程度偏倚。结论根据纳入的研究资料显示,针刺或针刺与其他治疗方法结合治疗神经性耳鸣的疗效高于单纯药物治疗或其他非针刺治疗方式；国内外文献标准不同,质量不一,研究方法迥异,故仍需更多的高质量大样本随机对照试验文献来进一步验证。
