摘  要:目的观察脐带间质干细胞(UMSCs)和骨髓间质干细胞(BMSCs)对CCl4诱导大鼠肝纤维化的治疗作用。方法通过S0%CCl4橄榄油皮下注射10周建立大鼠肝纤维化模型,随机平均分为UMSCs组、BMSCs组及空白对照组,UMSCs组经尾静脉输注1mlUMSCs(2×10^9/L),BMSCs组输注1mlBMSCs(2×10^9/L),空白对照组输注1ml生理盐水,移植处理3周后处死所有大鼠。抽取血液检测移植处理前后各组大鼠肝功能指标[谷丙转氨酶(ALT)、谷草转氨酶(AST)、总胆红素(TBIL)、白蛋白(ALB)],取肝脏标本苏木素-伊红(HE)染色行病理检查及量化计分。结果(1)移植处理3周后,与空白对照组大鼠AIJT、AST、TBIL指标[(637.60±42.38)U/L、(525.80±40.20)U/L、(17.26±0.68)μmol/L]比较,BMSCs组[(168.80±8.35)U/L、(352.00±33.64)U/L、(14.12±0.34)μmol/L]和UMSCs组[(163.60±7.30)U/L、(339.00±44.94)U/L、(13.96±0.29)μmol/L]均降低,差异均有统计学意义(P〈0.05),ALB指标差异无统计学意义(P〉0.05);与BMSCs组比较,UMSCs组大鼠ATJT、AST、TBIL及ALB指标差异均无统计学意义(P〉0.05)。(2)与移植处理前各组AlJT、AST、TBIL指标[空白对照组:(337.80±13.97)U/L、(436.40±23.27)U/L、(15.20±0.57)μmol/L;BMSCs组:(337.40±14.10)U/L、(439.40±15.27)U/L、(15.52±0.47)μmol/L;UMSCs组:(337.40±16.21)U/L、(437.20±25.15)U/L、(15.54±0.72)μmol/L]比较,处理3周后BMSCs组和UMSCs组相应指标均降低,空白对照组相应指标均升高,差异均有统计学意义(P〈0.05);移植处理前后各组大鼠ALB指标差异无统计学意义(P〉0.05)。(3)与空白对照组比较,BMSCs组和UMSCs组肝脏炎症活动度及纤维化程度均减轻,量化计分(空白对照组:13.20�Objective To investigate and compare the therapeutic effect of human umbilical cord mesenchymal stem ceils (UMSCs) and bone marrow mesenchymal stem cells (BMSCs) on hepatic fibrosis in rats induced by carbon tetrachloride (CC14 ). Methods Hepatic fibrosis model of Wistar rats were induced by subcutaneous injection of CC14 oily mixture continuously for 10 weeks. Then the rats were randomly divided into UMSCs group, BMSCs group and control group. UMSCs group was treated by infusion of 1 ml UMSCs suspension (2 × 10^9/L) via the caudal vein, BMSCs group with 1 ml BMSCs suspension, and control group with 1 ml normal saline. The treatment had last for 3 weeks. The blood of the rats was taken to measure liver function before and after the treatment. Also the hepatic tissues were taken to observe and evaluate pathological changes by HE staining. Results The levels of plasma ALT, AST and TBIL were reduced significantly in BMSCs group [ ( 168. 80 ± 8. 35 ) U/L, ( 352.00 ± 33.64) U/L, ( 14. 12 ±0. 34) μmol/L vs. (337.40±14.10) U/L, (439.40 ±15.27) U/L, (15.52 ±0.47) μmol/L] and UMSCs group [(163.60±7.30) U/L, (339.00 ±44.94) U/L, (13.96 ±0.29) panol/L vs. (337.40 ± 16.21) U/L, (437.20±25.15) U/L, (15.54 ±0. 72) μmol/LJ a^ter transplantation, roughly the reverse condition in control group [ (637. 60 ±42. 38) U/L, (525. 80 ±40..20)U/L, (17.26 ±0. 68)μmol/L vs. (337. 80 ±13.97) U/L, (436.40 ±23.27) U/L, (15.20 ±0.57) μmol/L], all P〈0.05. However, none of these groups had reduced the level of plasma ALB (P〉0. 05), As compared with control group (,13.20 ± 1. 79, 15.90 ±5. 28), both BMSCs group (4. 70 ± 1.57, 6. 00 ± 1.70) and UMSCs group (4. 30 ± 1.79, 5.90 ± 0. 82) obtained better pathological evaluations of the inflammation mobility as well as the degree of hepatic fibrosis ( P 〈 0. 05 ). And there was no significant difference between UMSCs group and BMSCs group (P 〉 0. 05). Co
