文摘目的:基于Meta分析方法,系统评价经颅黑质超声检查(transcranial sonography,TCS)对帕金森病(Parkinson disease,PD的诊断价值。方法:计算机检索PubMed、Embase、Cochrane图书馆及中国期刊全文数据库(CNKI)、中国科技期刊全文数据库(VIP)、中国生物医学文献数据库(CBM)中公开发表的文献,收集近十年有关TCS诊断PD的中英文文献,检索时限自2010年1月至2019年11月。由2名评价员根据纳入与排除标准,独立筛选文献、评价文献质量并提取相关资料。采用Meta-DiSc1.4软件进行Meta分析,根据异质性结果选择相应效应模型,汇总效应量及其95%CI,绘制受试者工作特征(receiver operator characteristic,ROC)曲线,并计算曲线下面积(area under the curve,AUC)及Q指数。最后应用Stata 12.0软件绘制Deek’s漏斗图评估发表偏倚。结果:共检索到相关文献753篇,严格按照纳入与排除标准筛选后,最终纳入28篇研究文献。Meta分析结果显示:TCS诊断PD的合并敏感度=0.82(95%CI=0.80~0.83);合并特异度=0.90(95%CI=0.88~0.91);合并诊断比值比=42.84(95%CI=28.37~64.68);合并阳性似然比=7.46(95%CI=6.11~9.11);合并阴性似然比=0.19(95%CI=0.15~0.25;SROC AUC为0.9470;Q指数为0.8865。结论:作为一种新型的神经疾病辅助检查方法,TCS在PD的诊断上展现出较高的诊断价值,且该技术兼具有无创、无辐射、经济、易操作等优点,故可将其作为PD早期筛查及辅助诊断工具推广应用。
