摘要 目的检测儿童哮喘急性发作期血清miR-21与白介素12(IL-12)的水平及其在哮喘发病中的作用。方法选取支气管哮喘儿童60例,并选取同时期60例健康儿童作为对照组,通过逆转录.聚合酶链反应(RT-PCR)和酶联免疫吸附实验(ELISA)分别检测各组血清miR-21与IL-12的含量,并对哮喘患儿血清中miR-21、IL-12和肺功能的关系进行相关性分析。结果儿童哮喘急性发作期血清中miR-21相对表达量明显高于对照组(P〈0.01),血清IL-12水平明显低于对照组(P〈0.01)。血清中miR-21在轻度、中度和重度哮喘患者中的表达水平呈逐渐上升趋势,各组间差异有统计学意义(R〈0.01);血清中IL-12在轻度、中度和重度哮喘患者中的表达水平呈逐渐下降趋势,各组间差异有统计学意义(P〈0.01)。血清中miR-21的相对表达量与FEVI%和PEF%均呈负相关,而血清中IL-12的含量与FEVI%和PEF%均呈正相关。结论miR-21与IL-12可作为儿童哮喘急性发作期的疾病严重性的标志物,可能参与了支气管哮喘的发病。
