氧化苦参碱对慢性乙肝和肝硬化患者血清MMP-2和TIMP-2的影响

目的 观察氧化苦参碱对慢性乙型病毒性肝炎（简称慢乙肝）和乙型肝炎后肝硬化（简称肝硬化）患者血清基质金属蛋白酶-2（MMP-2）和基质金属蛋白酶-2组织抑制因子（TIMP-2）以及肝纤维化指标透明质酸（HA）、层粘连蛋白（LN）和Ⅳ型胶原（ⅣC）]的影响.方法 慢乙肝（36例）和肝硬化（36例）患者用氧化苦参碱治疗前后采用ELISA方法检测血清MMP-2、TIMP-2,采用放射免疫法检测HA、LN、ⅣC的变化,并分析MMP-2、TIMP-2和肝纤维化指标之间相关性.结果 氧化苦参碱能降低慢乙肝中、重度和肝硬化Child-pugh A、B、C级血清HA、LN、ⅣC水平及血清MMP-2水平（与本组治疗前比较,P＜0.05）.血清MMP-2、TIMP-2水平分别与HA、LN、ⅣC均有良好相关性（P＜0.01）.结论 MMP-2、TIMP-2可用来评价纤维化情况,氧化苦参碱有一定抗肝纤维化作用.

Effect of Oxymatrine on Serum Matrix Metalloproteinase-2 and its Inhibitor in Patients with Chronic Hepatitis B and Liver Cirrhosis

OBJECTIVE: To observe the effect of oxymatrine on the level of serum matrix metalloproteinase-2 (MMP-2) and its inhibitor (TIMP-2) in patients with chronic hepatitis B (CHB) and post-hepatitis B liver cirrhosis (LC), as well as on liver fibrosis indexes as hyaluronic acid (HA), laminin (LN) and IV type collagen (IV C). METHODS: Changes of all the above-mentioned indexes in patients with CHB (n = 36) and LC (n = 36) before and after treatment were determined, and the relationship of MMP-2 and TIMP-2 with liver fibrosis indexes were analyzed. RESULTS: Oxymatrine could decrease the levels of MMP-2, HA, LN and IV C in patients with severe or moderate CHB and LC of Child-pugh A, B and C grade, as compared with the data before treatment (P < 0.05). Serum level of MMP-2 and TIMP-2 was well correlated with the levels of liver cirrhosis indexes. CONCLUSION: MMP-2 and TIMP-2 can be used as a reference for evaluating the degree of LC, and oxymatrine has a certain anti-LC effect.
