摘要
目的观察截断逆挽方对慢加急性肝衰竭(ACLF)大鼠血清和肝组织白细胞介素-6(IL-6)、肿瘤坏死因子-α(TNF-α)含量及肝细胞超微结构的影响,探讨其部分作用机制。方法采用人血清白蛋白免疫诱导肝纤维化联合D-氨基半乳糖/脂多糖急性攻击建立ACLF大鼠模型。将SPF级Wistar雄性大鼠随机分为正常组、模型组和截断逆挽方组(中药组),中药组在急性攻击24 h后给予截断逆挽方连续灌胃,5、10、15 d后平行取材。透射电镜观察肝细胞超微结构变化,ELISA检测血清及肝组织IL-6、TNF-α含量。结果与正常组比较,模型组各时间点大鼠血清及肝组织IL-6、TNF-α含量增加;与模型组比较,中药组血清及肝组织IL-6、TNF-α呈下降趋势,15 d改善最明显。透射电镜观察模型组大鼠肝细胞超微结构损伤程度随时间延长逐渐加重,各对应时间点中药组损伤程度明显减轻。结论截断逆挽方能有效降低大鼠血清及肝组织IL-6、TNF-α水平,减轻肝细胞损伤,对肝细胞结构和功能有一定的保护作用。
Objective To observe the effects of Jieduan Niwan Prescription on IL-6 and TNF-α in serum and hepatic tissue in acute-on-chronic liver failure rats（ACLF）; To study the partial mechanism of the treatment for ACLF. Methods The ACLF rat model was established by using human serum albumin immuno-induced hepatic fibrosis followed with D-galactosamine and lipopolysaccharide joint acute attack. The SPF Wistar male rats were randomly divided into normal group, model group and Jieduan Niwan Prescription group, respectively. The Jieduan Niwan Prescription group was treated by Jieduan Niwan Prescription after the acute attack for 24 h, and the rats were sacrificed respectively at 5, 10 and 15 days after gavage administration. Transmission electron microscope was employed to observe the ultrastructural changes in liver cells and ELISA was used to detect the contents of IL-6 and TNF-α in serum and liver tissue, respectively. Results Compared with the normal group, the contents of serum and liver tissue IL-6 and TNF-α in model group increased at each time point. Compared with the model group, the contents of serum and liver tissue IL-6 and TNF-α decreased in Jieduan Niwan Prescription group, especially in 15 days. Under the transmission electron microscope, the changes of ultrastructure of liver tissue were observed. With the passage of time, the degree of hepatocyte injury in model group gradually increased, but decreased significantly in Jieduan Niwan Prescription group at each time point. Conclusion Jieduan Niwan Prescription can effectively reduce the levels of IL-6 and TNF-α in serum and liver tissue, reduce the degree of liver damage, and has a certain protective effect on the liver.
