摘要 检测miR-145在炎症性肠病(IBD)患者外周血单核细胞(PBMCs)表达和Ⅰ型辅助性T细胞(Th1)/Ⅱ型辅助性T细胞(Th2)水平,探讨其与IBD发病关系。IBD患者89例,活动期组46例和缓解期组43例为IBD组,健康体检人员90例为对照组,采用实时荧光定量PCR(qRT-PCR)法检测PBMCs中miR-145表达水平,流式细胞术检测Th1/Th2,采用酶联免疫吸附法检测血清肿瘤坏死因子-α(TNF-α)、干扰素-γ(IFN-γ)、白细胞介素-4(IL-4)、白细胞介素-12(IL-12)、C-反应蛋白(CRP)、红细胞沉降率(ESR)水平,Pearson法分析IBD患者PBMCs中miR-145表达与Th1/Th2相关性。结果显示,与对照组比较,IBD患者血清中CRP、ESR水平明显增高(P<0.05),缓解期组与活动期组IBD患者,miR-145表达水平显著降低(P<0.05),Th1细胞亚群比例、Th1/Th2、血清TNF-α、IFN-γ、IL-4、IL-12水平显著升高(P<0.05);与缓解期比较,活动期组IBD患者miR-145表达水平显著降低(P<0.05),Th1细胞亚群比例、Th1/Th2、血清TNF-α、IFN-γ、IL-4水平显著升高(P<0.05);miR-145表达与Th1/Th2比值呈负相关(r=-0.442,P<0.05)。结果表明,IBD患者PBMCs中miR-145低表达,Th1/Th2比值显著升高,二者呈负相关,与IBD密切相关。
