慢性阻塞性肺疾病(chronic obstructive pulmonary disease,COPD)发病机制尚不清楚,目前最被接受的是蛋白酶/抗蛋白酶失衡学说[1,2]。基质金属蛋白酶-9(matrixmetalloproteinases-9,MMP-9)可能在COPD的发展中起重要作用。组织金属蛋白
The pathogenesis of chronic obstructive pulmonary disease (COPD) is unclear, and the most accepted protease / protease imbalance theory [1,2] is currently accepted. Matrixmetalloproteinases-9 (MMP-9) may play an important role in the development of COPD. Tissue protein
