[摘要] 目的 研究髓样细胞触发受体-1在肺炎中的诊断价值。 方法 系统检索Medline、Embase、Cochrane Library、中国生物医学文献数据库、中国生物医学期刊文献数据库等数据库，收集利用髓样细胞触发受体-1诊断肺炎的文献。利用QUADAS评分工具评价纳入文献的质量。数据分析采用Meta-Disc 1.4软件检验异质性，并根据异质性结果选择相应的效应模型，计算合并敏感度、特异度、阳性似然比、阴性似然比、诊断优势比及其95% CI。绘制汇总受试者工作特征(SROC)曲线，对诊断性试验的准确性进行综合评估。 结果 共有9篇文献共计889例样本纳入本次meta分析，分析结果显示髓样细胞触发受体-1对肺炎的诊断价值分别为：合并敏感度0.74(95% CI 0.70～0.78)，合并特异度0.68(95% CI 0.63～0.72)，阳性似然比2.67(95% CI 1.66～4.28)，阴性似然比0.34(95% CI 0.20～0.57)，诊断优势比 10.76(95% CI 3.89～29.69)，SROC曲线下面积为0.84。 结论 髓样细胞触发受体-1在肺炎的诊断中具有一定的临床价值，其检测结果的解读需要综合考虑患者的临床症状和其他检测指标。

[Abstract] Objective To assess the value of triggering receptor expressed on myeloid cells-1 (TREM-1) in the diagnosis of pneumonia. Methods A systematic review was conducted in Medline, Embase, Cochrane Library, Chinese Bio-medicine Database, and China Hospital Knowledge Database to identify relevant studies on evaluation of TREM-1 in the diagnosis of pneumonia. The methodological quality of each study was assessed by QUADAS. Statistical analysis was performed by employing Meta-Disc 1.4 software. Heterogeneity of the included articles was evaluated for selecting proper effect model to calculate pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnostic odds ratio and 95% CI. Summary receiver operating characteristic (SROC) curve was made and the area under the curve (AUC) was calculated. Results Nine studies with 889 samples met the inclusion criteria for present analysis ......
