【摘要】 目的　探讨支气管哮喘 (简称哮喘 )患者血浆肾上腺髓质素 (ADM)的质量浓度变化及其临床意义。方法　用放射免疫分析法测定 2 3例哮喘急性发作期患者和 18例缓解期患者血浆ADM质量浓度 ,并与动脉血氧分压 [Pa(O2 ) ]及 1秒钟用力呼气容积占预计值的百分比 (FEV1 % )进行相关分析。 2 0例健康人为正常对照组。结果　哮喘急性发作期组血浆ADM质量浓度 [( 2 8 73± 7 12 )ng L]高于缓解组 [( 13 85± 4 48)ng L ,P <0 0 1]和正常对照组 [( 11 78± 4 2 9)ng L ,P <0 0 1],并与 Pa(O2 )及FEV1 %呈负相关 ( r=- 0 5 5 ,P <0 0 1,r=- 0 63 ,P<0 0 1)。哮喘缓解期组血浆ADM质量浓度与Pa(O2 )及FEV1 %无显著相关性 (P >0 0 5 )。结论　ADM可能参与了哮喘的急性发作和炎症反应过程更多还原

【Abstract】 Objectives To investigate the clinical significance of plasma adrenomedullin (ADM) concentrations in patients with asthma.Methods The plasma ADM concentrations in 23 asthmatic patients with an acute attack and 18 asthmatic patients in remission stage were measured by radioimmunoassay.Linear regression analysis was used to evaluate the correlations between two variables.Twenty healthy subjects served as a normal control group.Results The plasma ADM concentrations in asthmatic patients with an acute attack [(28.73±7.12)ng/L]were significantly higher than those of stable asthmatic patients [(13.85±4.48)ng/L,P<0.01]and normal control group[(11.78±4.29)ng/L,P<0.01],and correlated negatively with Pa(O 2)(r=-0.55,P<0.01) and FEV 1%(r=-0.63,P<0.01) respectively.The plama ADM concentrations in stable asthmatic patients had no significant correlations with Pa(O 2) and FEV 1%(P>0.05).Conclusion The results suggest that ADM is involved in the pathophysiological process of acute asthma attack and may play an important role in the inflammation of asthmatic airways.更多还原
