摘要 目的观察支气管哮喘患儿痰液嗜酸性粒细胞(Eos)比例、基质金属蛋白酶9(MMP-9)水平变化,并探讨其意义。方法支气管哮喘患儿40例(观察组),同期健康体检儿童40例(对照组),采用诱导痰技术检测两组痰液Eos比例,采用双抗体夹心ABC-ELISA法测定MMP-9。结果与对照组比较,观察组急性发作期、临床缓解期Eos比例增加,急性发作期MMP-9水平升高(P<0.01);与临床缓解期比较,急性发作期Eos比例增加、MMP-9水平升高(P<0.01)。观察组急性发作期、临床缓解期MMP-9水平与Eos比例均呈正相关(r分别为0.89、0.92,P均<0.01)。结论支气管哮喘患儿痰液Eos比例增加,MMP-9水平升高,两者与患儿气道病变关系密切,且能较好反映哮喘患儿气道炎症状况。
