摘要 目的:通过对吸入糖皮质激素治疗前后哮喘患儿血浆血小板活化因子(PAF)水平的变化的观察,进一步探讨其临床意义。方法:采用生物学检测法,检测哮喘急性发作期患儿血浆PAF浓度及吸入糖皮质激素治疗后血浆PAF浓度,并以同期体检健康儿童24例作为对照。结果:哮喘急性发作期患儿血浆PAF浓度吸入糖皮质激素治疗前较治疗后明显增高,差异有显著性(t=2.458,P<0.05),经吸入糖皮质激素治疗后患儿血浆PAF浓度降至正常水平,与对照组比较差异无显著性(t=1.527,P>0.05)。结论:PAF作为一种重要的继发性炎性介质,其生成和释放参与了哮喘患儿气道慢性炎症、高反应性和可逆性阻塞的形成。糖皮质激素抑制了磷脂酶A2的活性,从而抑制了PAF的生成与释放。
