摘要 目的:对基质金属蛋白酶(MMPs)及其抑制物与慢性阻塞性肺疾病(COPD)的关系进行探讨。方法:检索近年与COPD发病相关的文献,分析COPD的发病与肺部蛋白酶和抗蛋白酶失衡的相关性,以及参与COPD发病的相关蛋白酶。结果:MMPs的表达和酶活性受MMPs抑制剂(TIMPs)等多种因素调节,MMPs增多将导致蛋白酶过度水解细胞外基质,使肺组织失去弹力,肺泡腔扩大,致COPD形成;加上抗蛋白酶不足或蛋白酶增加均可致肺组织结构破坏,最终形成阻塞性肺气肿,进而发展成为COPD。结论:MMPs和TIMPs的失衡可能在COPD的发病中起重要作用,因而维持两者之间的平衡可能为临床治疗COPD提供了新的思路。
