探讨血、尿NAG水平对诊断肝硬化的价值。方法测定 46例肝硬化患者及 30例健康者晨尿、晨血NAG水平并经过统计学处理。结果肝硬化患者血、尿NAG水平明显高于正常对照 ,失代偿期明显高于代偿期。结论血、尿NAG活力测定及对其动态观察 ,可较灵敏反映肝硬化早期是否合并肾脏损害 ,并可间接判断肝硬化对肝功能的损害程度 ,对肝硬化的发展、预后、疗效监测具有重要价值。 To investigate the value of blood and urine NAG in the diagnosis of cirrhosis. Methods The morning urine and morning blood NAG levels in 46 cirrhotic patients and 30 healthy controls were determined and statistically analyzed. Results The levels of blood and urine NAG in patients with cirrhosis were significantly higher than those in normal controls, and decompensation was significantly higher than those in compensated patients. Conclusion The determination of blood and urine NAG activity and its dynamic observation can be more sensitive to reflect the early stage of cirrhosis combined with renal damage, and indirectly determine the degree of liver cirrhosis damage to liver function, the development of cirrhosis, prognosis, efficacy monitoring is important value.
