文摘目的:评估外周血microRNA(miR)-21、血浆聚腺苷二磷酸核糖聚合酶1[poly(ADP-ribose)polymerase-1,PARP-1]在过敏性鼻炎(allergic rhinitis,AR)和过敏性鼻炎-哮喘综合征(combined allergic rhinitis and asthma syndrome,CARAS)中的诊断价值。方法:收集44例CARAS患者、31例AR患者和42例健康对照的外周血,采用RT-qPCR法检测外周血中miR-21的表达水平,采用ELISA法检测血浆中PARP-1蛋白水平。应用Pearson进行相关性分析。受试者工作特征(receiveroperatingcharacteris-tic,ROC)曲线判断miR-21和PARP-1的诊断灵敏度与特异度。结果:CARAS组患者外周血miR-21的表达较健康对照组升高。AR组患者血浆PARP-1的水平较CARAS组和健康对照组升高。Pearson相关性分析结果显示,外周血miR-21的表达水平在AR患者中与嗜酸性粒细胞计数相关,在CARAS患者中与鼻呼出气一氧化氮(fractionalnasalnitricoxide,FnNO)水平相关;血浆PARP-1在AR患者中与1秒钟用力呼气量占预计值百分比(forced expiratory volume in onesecond percent predicted,FEV1%pred)相关,在CARAS患者中与FEV1%pred及1秒钟用力呼气量(forced expiratory volume in one second,FEV1)/用力肺活量(forced vital capacity,FVC)(FEV1/FVC)相关。ROC曲线分析显示,外周血miR-21作为CARAS的诊断标志物时,灵敏度为51.35%,特异度为80.95%。血浆PARP-1作为AR的诊断标志物时,灵敏度为90.32%,特异度为54.76%。血浆PARP-1作为AR进展为CARAS的诊断标志物时,灵敏度为45.45%,特异度为90.32%。结论:AR和CARAS患者外周血miR-21、PARP-1存在差异表达,外周血miR-21可作为CARAS的诊断标志物,PARP-1可作为AR的诊断标志物及AR进展为CARAS的生物标志物。这对寻求AR和CARAS的诊治靶点有十分重要的价值。
