非酒精性脂肪肝肝纤维化指标的检测

目的：检测非酒精性脂肪肝肝纤维化指标，探讨其临床意义。方法：符合B超诊断的非酒精性脂肪肝患者作肝纤维化指标检测，并以肝炎后肝硬化患者和不嗜酒的健康者作为对照。结果：脂肪肝患者Ⅲ型前胶原(PC Ⅲ）、透明质酸(HA)、Ⅳ型胶原(C Ⅳ)、层粘蛋白(LN)均高于健康者(P＜0．05—0．01)，低于肝硬化患者(P＜0．01)；重度脂肪肝与轻度脂肪肝之间PC Ⅲ、C Ⅳ、LN差异均有显著性(P＜0．05—0．01)，且阳性率较高。结论：重度脂肪肝患者存在不同程度的肝纤维化趋向，肝纤维化指标的多项联检对脂肪肝肝纤维化的判断与防治有积极意义。

Liver fibrosis indexes in nonalcoholic fatty liver disease

OBJECTIVE: To assess the clinical utility of liver fibrosis indexes determination in patients with nonalcoholic fatty liver disease. METHODS: Liver fibrosis indexes of 79 patients with fatty liver, diagnosed by B ultrasonic echography, 37 patients with posthepatitic cirrhosis patients and 32 healthy subjects were determined. RESULTS: The level of procollagen III(PC III), hyaluronic acid (HA), collagen IV(C IV), laminin (LN) in the fatty liver cases were significantly higher than those of healthy subjects (P<0.05 - 0.01), but lower than those in the liver cirrhosis cases (P<0.01). The difference of PC III, C IV, LN between the severe and early fatty liver cases was significant (P<0.05 - 0.01). Positive rate of these indexes was higher in severe cases. CONCLUSION: There is a trend of liver fibrosis in severe fatty liver patients. Combined determination of liver fibrosis indexes may help the diagnosis of liver fibrosis in the fatty liver patients.
