血小板活化因子在肝肾综合征中的作用

目的：研究血小板活化因子（PAF）与肝肾综合征（HRS）的关系。方法：分别检测同期住院的25例有HRS并发症和32例无HRS并发症的肝硬化、重型肝炎患者血液中PAF，内毒素(LPS)及凝血酶原活动度（PTA）、总胆红素、肌酐等指标，分析PAF，LPS水平与肝、肾功能的相关性。结果：并发HRS的肝硬化、重型肝炎患者PAF，LPS及总胆红素水平明显高于无HRS并发症的肝硬化、重型肝炎患者；血PAF与LPS，PTA，总胆红素及肌酐水平呈直线相关。结论：PAF与HRS形成有关；形成机制可能是通过PAF介导LPS所致；PAF水平对肝衰竭患者HRS的发生可能有一定预测作用。

Role of platelet activating factor in hepatorenal syndrome

Objective To investigate the relationship between platelet activating factor (PAF) and occurrence of hepatorenal syndrome (HRS). Methods A total of 57 cases of patients with liver cirrhosis or hepatitis gravis were enrolled.The serum concentrations of PAF, lipopolysaccharide (LPS) and prothrombin activity (PTA), total bilirubin, and serum creatinine were detected in patients combined with HRS and in patients without HRS in hospital at the term. The correlations among the PAF, LPS, and the function of liver and kidney were analyzed. Results The concentrations of PAF and LPS in the patients combined with HRS were significantly higher than those patients without HRS. There were linear correlations between the PAF and LPS level, the total bilirubin level and PAF level, the PAF level and serum creatinine level. Conclusion The PAF associates with the occurrence of HRS. The PAF may mediate the occurrence of HRS induced by LPS. The PAF level may forecast whether patients with liver failure will take place HRS.
