[摘 要] 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(receiver operating characteris⁃
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(fractional nasal nitric oxide,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 one second 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。

[Abstract] Objective:To evaluate the diagnostic value of peripheral blood microRNA(miR)⁃21 and plasma poly(ADP⁃ribose)
polymerase⁃1(PARP⁃1)in allergic rhinitis(AR)and combined allergic rhinitis and asthma syndrome(CARAS). Methods:Peripheral
blood samples were collected from 44 CARAS patients,31 AR patients,and 42 healthy controls. The expression levels of miR⁃21 in
peripheral blood were detected by RT⁃qPCR,and the plasma levels of PARP⁃1 protein were measured by ELISA. Correlation analysis
was performed by rearson correlation analysis. The diagnostic sensitivity and specificity of miR⁃21 and PARP⁃1 were determined by
receiver operating characteristic(ROC)curve. Results:The expression of peripheral blood miR ⁃ 21 was high in CARAS patients
compared with healthy controls. The level of PARP⁃1 was higher in AR patients than that in CARAS patients and healthy controls.
Pearson correlation analysis showed that the expiression of miR⁃ 21 was correlated with eosinophils count in AR patients and with
fractional nasal nitric oxide(FnNO)in CARAS patients. The plasma level of PARP⁃1 was correlated with forced expiratory volume in
one second percent predicted(FEV1% pred)in CARAS patients and with FEV 1% pred and forced expiratory volume in one second(FEV1)/
