地塞米松雾化吸入对哮喘患者诱导痰液中ECP、TNF-α、sIL-2R水平的影响
Shaanxi Medical Journal(2010)
Abstract
目的:诱导测定哮喘患者痰液ECP、TNF-α、slL-2R水平,评价吸入地塞米松防治哮喘的作用。方法:采用酶联免疫法及荧光免疫法对40例轻中度哮喘患者在吸入激素前后测定痰液中嗜酸细胞阳离子蛋白(ECP)、肿瘤坏死因子-α(TNF-α)、可溶性白细胞介素2受体(slL-2R)水平。结果:吸入激素后诱导痰液ECP水平由300±122μg/L降至146±96μg/L、TNF-α由280±135ng/L降至132±53ng/L、slL-2R由497±136kU/L降至328±97kU/L。哮喘患者吸入激素前ECP与TNF-α,slL-2R均呈显著正相关(r=0.58,0.62,P<0.05)。吸入激素后各指标间无显著相关性。结论:吸入激素后哮喘患者诱导痰液中ECP、TNF-α、slL-2R浓度比吸入激素前明显降低。吸入激素可明显抑制气道炎性反应,其作用机制可能与抗炎作用有关。
