摘要/Abstract

摘要： 目的研究人工肝支持系统(ALSS)治疗急性肝衰竭的效果。方法将11只实验小型猪分为治疗组(n=6)和对照组(n=5),均给予D-氨基半乳糖,建立急性肝衰竭模型;治疗组48 h后经人工肝血浆置换结合血液滤过联合治疗。观察2组的一般情况、生存时间、生化指标和肝脏病理学变化。结果治疗组经人工肝治疗72 h后,一般状况有所改善,生存时间为(128.7±11.3)h,与对照组〔(67.9±9.4)h〕相比差异有统计学意义(P<0.01)。治疗组的丙氨酸转氨酶(ALT)、总胆红素(TBil)、凝血酶原时间(PT)与同组治疗前和对照组相比均有明显改善(P<0.01)。2组增殖细胞核抗原(PCNA)的阳性表达率比较差异有统计学意义(P<0.05)。治疗组与对照组的HE染色标本相比,肝脏坏死区域明显缩小,未发现明显淤胆。结论人工肝治疗急性肝衰竭效果显著,可以减少坏死区,提高肝细胞再生率,延长存活时间。

Abstract: Objective To study the therapeutic effects of artificial liver support system treatment for in acute liver failure.Methods Eleven miniature pigs were divided into the therapeutic and control groups.Pigs were given D-galactosamine to build models of acute liver failure.Pigs in the therapeutic group were treated after 48 h with plasma exchange and hemofiltration of the artificial liver support system(ALSS).Four parameters were observed: survival time,common condition,biochemical assay,changes in liver pathology.Results The survival time(128.7±11.3) h in the therapeutic group were remarkably different from those in the control group(67.9±9.4)h in terms of improvements in the common condition,as well as ALT,TBil and PT levels(P<0.01).Area of necrosis was obviously reduced in the therapeutic group,and cholestasis was not found.Conclusion Treatment of acute liver failure by ALSS in pig model is very effective.

Key words: ALSS, ALF, PCNA, biochemical assay, changes in hepatic pathology
