Effect of oxymatrine on serum matrix metalloproteinase-9 and transforming growth factor-β1 in patients with idiopathic pulmonary fibrosis / 中国医师进修杂志

ABSTRACT

Objective To study the effect ofoxymatrine on serum matrix metalloproteinase-9 (MMP-9)and transforming growth factor-β 1 (TGF-β 1) in patients with idiopathic pulmonary fibrosis (IPF) and illuminate the mechanism and action.Methods Total 38 patients with IPF in the patient group were divided into the conventional treatment group and the oxymatrine group by random digits table method with 19 cases each.Meanwhile 38 healthy people were as the control group.Then serum MMP-9 and TGF-β1 levels were detected by enzyme-linked immunosorbent assay and compared.Results The serum MMP-9 level in the control group and the patient group was (92.30 ± 27.21),(420.66 ± 101.78) μg/L,and there was significant difference (P ＜ 0.05).The serum TGF-β 1 level in the control group and the patient group was (67.36 ± 13.03),(217.82 ±43.90) μg/L,there was significant difference (P ＜0.05).There was no significant difference in the serum MMP-9 and TGF-β1 level before treatment between the conventional treatment group and the oxymatrine group (P ＞ 0.05).There was significant difference in the serum MMP-9 level before and after treatment in the conventional treatment group [(138.91 ± 35.09) μ g/L vs.(428.21 ±102.75) μ g/L] (P ＜ 0.05).There was no significant difference in the serum MMP-9 level before and after treatment in the oxymatrine group (P ＞ 0.05).There was significant difference in the serum TGF-β 1 level before and after treatment in the conventional treatment group and the oxymatrine group [(145.42 ± 30.78)μg/Lvs.(200.34±58.96)μg/L;(102.37±26.04) μg/Lvs.(219.78±63.20) μg/L](P＜0.05).There was significant difference in the serum TGF-β1 level after treatment between the conventional treatment group and the oxymatrine group (P＜ 0.05).Conclusion Oxymatrine can degrade IPF by reducing TGF-β 1 and maintaining MMP-9 in the higher level.
