Abstract

目的 分析支气管哮喘患儿治疗前后血浆内皮素-1(ET-1)、降钙素基因相关肽(CGRP)水平变化及临床意义.方法 用放射免疫法对60例支气管哮喘患儿按不同药物、哮喘的程度及发作与否分组测定ET-1和CGRP含量.结果 多巴胺(DP)组、多巴酚丁胺(DOB)组、酚妥拉明(PTL)组治疗前ET-1和CGRP含量分别为(117.6±7.5)ng/L、(102.1±12.3)ng/L,(112.4±6.5)ng/L、(104.1±10.3)ng/L,(120.6±6.5)ng/L、(99.1±9.3)ng/L,明显高于治疗后(69.9±8.6)ng/L)、(72.8±17.1)ng/L,(56.9±8.0)ng/L、(68.8±16.1)ng/L,(72.0±9.0)ng/L、(67.8±15.3)ng/L(P<0.05~0.01).60例支气管哮喘发作期ET-1和CGRP含量分别为(112.1±9.4)ng/L、(20.4±5.3)ng/L,明显高于支气管哮喘缓解期[(73.3±6.9)ng/L、(75.5±9.3)ng/L](P<0.01).治疗组缓解天数为(3.5±2.0)d,明显低于常规组(7.3±2.5)d(P<0.01).治疗组有效率为84%,高于常规组的73%(P<0.05).结论 血浆ET-1和CGRP含量的测定在判定支气管哮喘的程度及疗效有一定的临床价值。
