目的:研究骨髓间充质干细胞(hBMSCs)对慢加急性肝衰竭(ACLF)模型小鼠的治疗作用。方法:60只BALB/cJ小鼠随机分为正常组(n=8)和ACLF造模组(n=52),采用四氯化碳(CCl4)诱导法构建ACLF小鼠模型,ACLF造模组剔除死亡小鼠,随机分为模型组(n=11)、hBMSCs低剂量治疗组(n=12)、中剂量治疗组(n=12)、高剂量治疗组(n=12)。采用生化分析仪检测小鼠血清谷氨酸氨基转移酶(ALT)、天冬氨酸氨基转移酶(AST)、总胆红素(TBIL)、总蛋白(TP)和白蛋白(ALB)水平;超敏多因子发光法(MSD)检测血清白细胞介素(IL)-Iβ、IL-6、IL-10、肿瘤坏死因子-α(TNF-α)、趋化因子配体1(KC/GRO)水平含量;苏木素-伊红(HE)和Masson染色,评价肝组织病理损伤程度。结果:与正常组相比,模型组AST、ALT、TBIL、TP、ALB水平显著升高(F=5.409、26.27、21.20、23.44、22.81,均P<0.001),AST/ALT比值显著降低(F=3.036, P<0.05)。与ACLF模型组比较,hBMSCs低、中剂量治疗组血清AST、ALT、TBIL水平显著降低(均P<0.05);中、高剂量治疗组AST/ALT比值显著升高(均P<0.05);hBMSCs低剂量治疗组血清IL-6、KC/GRO水平显著降低(均P<0.05);hBMSCs低、中剂量治疗组IL-1β、TNF-α水平降低(均P<0.05),而在hBMSCs低、中、高剂量治疗组中IL-10均升高(均P<0.05);低、中、高剂量治疗组TP、ALB、IFN-γ、IL-2、IL-5差异没有统计学意义(均P>0.05); hBMSCs低、中剂量治疗组肝组织炎细胞浸润及坏死区域均显著减少(均P<0.05),肝组织胶原纤维阳性面积显著降低(均P<0.05)。结论:hBMSCs对CCl4诱导的ACLF小鼠模型具有显著的治疗作用, 治疗效果未见剂量依赖,其中低剂量组治疗效果更佳。

Objective: To evaluate the therapeutic potential of human bone marrow mesenchymal stem cells(hBMSCs) on acute-on-chronic liver failure (ACLF) mice model. Methods: A total of 60 BALB/cJ mice were randomly divided into healthy control group (n=8) and ACLF model group (n=52). ACLF mice was established by intraperitoneal injection of carbon tetrachloride(CCl4). ACLF model group excluded dead mice were randomly divided into model group (n=11), hBMSCs low dose group (n=12), medium dose group (n=12) and high dose group (n=12). The levels of aspartate aminotransferase(AST), alanine aminotransferase (ALT), total bilirubin (TBIL), total protein (TP), albumin (ALB) in mice were detect by a biochemical analyzer. Serum levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), interleukin-10 (IL-10), tumor necrosis factor-α (TNF-α) and chemokine ligand 1 (KC/GRO) were detected by MSD electrochemiluminescence technology. HE and Masson staining were used to evaluate the degree of pathological damage in liver tissue. Results: Compared with the control group, the serum level of TBIL, AST, ALT, TP and ALB were significantly increased(F=5.409, 26.27, 21.20, 23.44, 22.81, all P<0.001), AST/ALT was significantly decreased(F=3.036, P<0.05). Compared with the ACLF model group, the serum level of TBIL, AST and ALT were significantly decreased in the low, and medium dose group (all P<0.05), AST/ALT was significantly increased both in medium and high dose group (all P<0.05). The serum levels of pro-inflammatory cytokines IL-6 and KC/GRO were significantly decreased in low dose group (all P<0.05). IL-1β and TNF-α were significantly decreased in low, and medium dose group (all P<0.05),while anti-inflammatory cytokines IL-10 was significantly increased in the treated groups(all P<0.05). TP, ALB, IFN-γ, IL-2 and IL-5 were not significantly changed in all the treated groups(all P>0.05). The infiltration and necrosis area of inflammatory cells in the low and medium groups were significantly decreased (both P<0.05), and the positive area of collagen fibers in liver tissue was significantly reduced(both P<0.05). Conclusion: hBMSCs has an obvious therapeutic effect on CCl4-induced ACLF mice model and the therapeutic effect is not dose-dependent. In contrast, low-dose group has better therapeutic effect.
