Abstract:
Objective To investigate the change of MMP-9,TIMP-1,ICAM-1 and VCAM-1 expression in serum from patients with COPD,as well as the correlation between the expressions of these factors and lung function.Methods Enzyme-linked Immunosorbent Assay(ELISA)was used to determine the levels of MMP-9,TIMP-1,ICAM-1 and VCAM-1 in serum from 58 patients with COPD and 30 samples from healthy donors in order to better understand the correlation between the expression of these factors and airflow obstruction.Results The serum levels of MMP-9,TIMP-1,ICAM-1 and VCAM-1[(128.89?115.84),(228.28?107.13),(203.98?70.37) and (352.98?117.73)?g/L]from patients with COPD were statistically and significantly higher than the control group[(30.65?18.43),(133.69?41.41),(148.35?23.77) and (233.57?36.65)?g/L],P
