【摘要】 目的 观察慢性乙型肝炎(CHB)、肝硬化(LC)患者血清转化生长因子-β1(TGF-β1)与肝细胞损伤、肝脏纤维组织增生的关系。方法 采用酶联免疫吸附试验(ELISA)测定76例CHB、LC患者血清TGF-β1。肝活检29例,应用多媒体彩色图文分析系统对肝内胶原纤维、网状纤维进行定量分析。结果 (1) CHB轻、中、重度、LC患者血清TGF-β1水平分别为(144.3±57.1)mg/L、(394.5±107.7)mg/L、(508.3±133.3)mg/L、(579.4±225.1)mg/L,依次升高(P<0.01或P<0.05);明显高于对照组(95.3±34.1)mg/L(P<0.01)。(2) 血清TGF-β1与Ⅲ型前胶原蛋白(PCⅢ)、层粘连蛋白(LN)、透明质酸(HA)呈正相关(P<0.01或P<0.05);血清TGF-β1升高与肝组织纤维化程度的加重、肝组织内胶原纤维、网状纤维含量的增长呈同步性(P<0.01或P<0.05)。(3) ALT>160U/L组、SB>85.5μmol/L组血清TGF-β1水平明显高于肝功能轻度异常和正常组(P<0.01或P<0.05)。结论 TGF-β1在CHB肝纤维化的发病机制中起着不可忽视的作用,血清TGF-β1的检测可用于CHB肝纤维化程度和肝细胞受损程度的判断。 【关键词】 转化生长因子-β1 肝硬化 肝组织病理

【Abstract】 Objective To observe the relationship between serum transforming growth factor-β1 (TGF-β1) and liver cell damage, procollagen Ⅲ (PCⅢ), Laminin (LN), hyaluronic acid (HA), proliferation of hepatic fibrotic tissue.Methods Serum TGF-β1 was detected by ELISA. Liver biopsy was performed in 29 patients with chronic hepatitis B(CHB)/liver cirrhosis (LC). Histopathological diagnoses and quantitative analysis for collagenous and reticular fibers were made.Results (1) Serum TGF-β1 levels in CHB and LC patients were notably higher than that in NC (95.3±34.1)mg/L(P<0.01) and increased by degrees in mild, moderate, severe CHB and LC (144.3±57.1)mg/L、(349.5±107.7)mg/L,(508.3±133.3)mg/L,(579.4±225.1)mg/L, (P<0.01 or P<0.05). (2) Serum TGF-β1 was positively correlated with serum level of PCⅢ, LN, HA (P<0.01 or P<0.05).
