摘要: 目的 探讨人脐带间充质干细胞(UCMSCs)移植对酒精性肝损伤大鼠的保护作用。方法 将40只SD大鼠随机分为4组,采用白酒灌胃法建立慢性酒精性肝损伤模型,给予UCMSCs移植或UCMSCs联合甘草酸经门静脉移植,在对照组和模型组给予生理盐水处理。检测血清丙二醛(MDA)、超氧化物歧化酶(SOD)和谷胱甘肽过氧化物酶(GPx)水平。采用RT-PCR法检测肝组织细胞色素P450亚酶(CYP2B1) mRNA水平。结果 模型组动物血清AST、ALT和MDA水平分别为(210.6±26.0) U/L、(111.2±13.7) U/L和(1.6±0.1)μmo/L,显著高于对照组的【(85.5±12.7) U/L、(30.8±4.5) U/L和(0.6±0.1) μmo/L,P<0.05】,而血清SOD和GPx水平分别为(141.3±6.9)U/L和(336.5±26.1) U/L,显著低于对照组的【(225.7±16.4) U/L和(912.3±29.5) U/L,P<0.05】;细胞移植或细胞移植联合甘氨酸处理组动物血清酶学变化得到很大的改善;与对照组比,模型组肝组织CYP2B1 mRNA水平显著降低;与模型组和细胞移植组比,细胞移植联合甘氨酸处理组肝组织CYP2B1 mRNA水平显著增强,差异有显著性统计学意义(P<0.05)。结论 脐带间充质干细胞移植对大鼠酒精性肝损伤有一定的保护作用,与甘草酸联合应用后,保护效果更加明显。

Abstract: Objective To investigate the protective effect of human umbilical cord mesenchymal stem cell (UCMSC) transplantation on alcoholic liver injury in rats. Methods 40 healthy SD rats were randomly divided into control (group A),model (group B),UCMSC transplantation (group C) and UCMSC as well as glycyrrhizic acid(group D) intervention. Serum levels of aspartate aminotransferase(AST),alanine aminotransferase (ALT),malondialdehyde (MDA),superoxide dismutase (SOD) and glutathione peroxidase (GPx) were measured and liver tissue cytochrome P450(CYP2B1) mRNA was detected by RT-PCR. Results Serum AST,ALT and MDA levels in the model were (210.6±26.0) U/L,(111.2±13.7) U/L and (1.6±0.1) μmo/L,significantly higher than 【(85.5±12.7) U/L,(30.8±4.5) U/L and(0.6±0.1) μmo/L,respectively,P<0.05】 in the control,while serum levels of SOD and GPx were (141.3±6.9) U/L and (336.5±26.1) U/L,significantly lower than 【(225.7±16.4) U/L and (912.3±29.5) U/L,P<0.05】 in the control;the liver injuries reflected by serum parameter changes improved in rats with UCMSCs transplantation or UCMSCs and glycyrrhizic acid intervention;the CYP2B1 mRNA level in liver tissues in model decreased obviously as compared to that in the control,while they intensified heavily in liver tissues in rats with cell transplantation or in rats with cell and glycyrrhizic acid intervention(P<0.05). Conclusion Umbilical cord mesenchymal stem cell transplantation might protect alcoholic liver injury in rats to a certain extent,and the combination of glycyrrhizic acid with cell transplantation might improve the protective effect.
