Abstract: 目的 探讨慢性阻塞性肺疾病急性加重期(AECOPD)患者的血清MMP-9、TIMP-1浓度的变化及其与肺通气功能变化的关系.方法 采用酶联免疫吸附(EL ISA)方法检测56例AECOPD患者和32名健康人血清中MMP-9、TIMP-1浓度.结果 AECOPD患者血清MMP-9、TIMP-1浓度[(126.89±113.84)ng/mL、(226.28±105.133)ng/mL]明显高于对照组[(28.65±16.43)ng/mL、(132.69±40.41)ng/mL,P<0.01].AECOPD组和对照组血清MMP-9、TIMP-1浓度与FEV1占预计值%具有负相关性(r=-0.591、-0.651,P<0.01);AECOPD组和对照组血清MMP-9、TIMP-1浓度与FEV1/FVC%具有负相关性(r=-0.558、-0.653,P<0.01);MMP-9/TIMP-1比率与FEV1占预计值%及FEV1/FVC%具有负相关性(r=-0.363、-0.356,P<0.05).结论 MMP-9、TIMP-1是引起肺通气功能下降很重要的因素.
