| 摘 要： | 目的探讨趋化因子IP-10及其受体CXCR3的表达在大鼠肝移植手术前后的动态变化,分析其与肝移植急性排斥(acute rejection,AR)的关系。方法改良"二袖套"法建立大鼠原位肝移植模型和急性排斥模型,分为4组:手术创伤组,肝移植无排斥组,肝移植急性排斥组,FK506组。ELISA法检测血清IP-10表达。流式细胞仪检测外周血淋巴细胞CXCR3的表达,用Cellquest软件分析阳性细胞百分率。半定量RT-PCR检测各组第7天肝脏组织CXCR3-mRNA的表达。结果①各组大鼠手术后外周血趋化因子IP-10及其受体CXCR3表达明显升高;②AR组在术后第5天起IP-10及其受体CXCR3表达均高于各对照组(P0.01);③AR组大鼠在移植后第7天,外周血IP-10和CXCR3的表达随着AR组RAI积分的升高而逐步升高,相关系数分别为0.89和0.92(P0.05)。结论血清中趋化因子IP-10及其受体CXCR3的高表达与AR密切相关,有望成为诊断AR较特异、敏感的指标。

| Abstract: | Objective To explore the dynamic changes of the expression of chemokine IP-10 and its receptor CXCR3 before and after liver transplantation in rats and to analyze the relationship between the role and the acute rejection(AR).Methods The model of orthotopic liver transplantation(OLT) of rats was established by two-cuff technique.Rats were randomed into 4 groups: Operation injury,OLT without AR,OLT with AR and OLT treated by FK506.The dynamic expression of IP-10 and CXCR3 was measured 1 day prior to OLT and 1... |
