| 摘 要： | 目的 探讨慢性乙型肝炎患者血清转化生长因子-β1(TGF-β1)与血清肝纤维化指标的关系,评价其对早期肝纤维化诊断的临床价值.方法 分别检测38例慢性乙型肝炎患者和10名健康者(对照组)血清中TGF-β1水平和透明质酸(HA)、层粘蛋白(LN)、Ⅳ型胶原(Ⅳ-C)、Ⅲ型前胶原(PC Ⅲ)水平.患者均行肝组织穿刺活检,标本进行常规HE染色和胶原纤维染色.结果 慢性乙型肝炎中、重度患者血清TGF-β1水平［(202±78)mg/L,(401±63)mg/L］显著高于对照组［(75±34)mg/L,P＜0.01］,HA、LN、IVC、PC Ⅲ水平随肝纤维化进展而呈逐渐升高.各组血清HA、LN、IVC、PC Ⅲ均与血浆TGF-β1呈明显正相关(P＜0.01).结论 慢性乙型肝炎患者血清TGF-β1水平与肝纤维化指标呈正相关,其对早期诊断出肝硬化具有重要意义.Abstract：Objective To study the relationship between serum level of TGF-β1 and hepatic fibrosis parameters in patients with chronic hepatitis B. Methods Serum TGF-β1 and hyalauronic acid(HA), laminin (LN), type Ⅳ collagen(Ⅳ-C) and type Ⅲ procollagen (PC Ⅲ) were detected by ELISA in 38 patients with chronic hepatitis B (CHB). Ten healthy persons served as controls. Liver puncture was performed in all patients with CHB. Results Serum TGF-β1 levels in moderate, severe CHB ［(202±78)mg/L,(401±63)mg/L］ were much higher than those of the control group ［(75±34)mg/L,P＜0.01］ and increased successively. TGF-β1 was correlated positively with serum levels of HA,LN,Ⅳ-C and PC Ⅲ (P＜0.01). Serum TGF-β1, PCⅢ, LN, Ⅳ-C and HA increased successively (P＜0.01) with aggravation of hepatic fibrosis. Conclusions Serum TGF-β1 levels of patients with CHB are consistent with serum indexes of hepatic fibrosis. It can help to judge the degree of hepatic tissue fibrosis.
