Abstract:
Objective To observe the effects of Angelicae Sinensis Radix-Paeoniae Radix alba combined with bone marrow mesenchymal stem cells(BM-MSCs)transplantation on liver inflammation and hepatocytes regeneration in non-alcoholic steatohepatitis(NASH)associated cirrhosis;To discuss its possible mechanism.Methods West diet combined with carbon tetrachloride was used to prepare the NASH related cirrhosis model.The mice were randomly divided into control group,model group,Angelicae Sinensis Radix-Paeoniae Radix alba group,BM-MSCs group,and Angelicae Sinensis Radix-Paeoniae Radix alba+BM-MSCs group,with 12 mice in each group.After successful modeling,corresponding interventions were given according to grouping for 4 consecutive weeks.HE staining was used to observe the morphology of liver tissue;the contents of serum ALT,AST,TBil,TG,ALB,AFP,as well as the contents of IL-1β,TNF-α and HGF in liver tissue were detected;RT-qPCR was used to detect TLR9,MyD88,TRAF6 and NF-κBp65 mRNA expression in liver cells;primary liver cells were separated,CpG ODN 2216 stimulation was induced in vitro,cells supernatant was extracted,and IL-1β and TNF-α content were detected.Results Compared with the control group,inflammatory cell infiltrated in liver tissue of model group mice,accompanied by hepatocyte necrosis and collagen deposition,forming pseudo lobules;the contents of serum ALT,AST,TBil and TG increased,the content of ALB decreased,the content of HGF in liver tissue decreased,the contents of IL-1β and TNF-α increased,with statistical significance(P<0.05);the mRNA expressions of TLR9,MyD88,TRAF6 and NF-κBp65 in liver cells increased(P<0.05),and the contents of IL-1β and TNF-α in cells supernatant increased after CpG ODN 2216 induction(P<0.05).Compared with the model group,the inflammatory infiltration in liver tissue and necrosis of liver cells were reduced and the degree of liver fibrosis was alleviated in the Angelicae Sinensis Radix-Paeoniae Radix alba+BM-MSCs group,the liver tissue damage in Angelicae Sinensis Radix-Paeoniae Radix alba group and BM-MSCs group were slightly improved;except for the TG content in BM-MSCs group,all detection indicators showed significant improvement in each intervention group(P<0.05).Compared with the Angelicae Sinensis Radix-Paeoniae Radix alba group and BM-MSCs group,the Angelicae Sinensis Radix-Paeoniae Radix alba+BM-MSCs group showed statistical significance in related detection indicators(P<0.05),and demonstrated a synergistic effect.Conclusion Angelicae Sinensis Radix-Paeoniae Radix alba combined with BM-MSCs transplantation could effectively improve the liver function and promote liver cell regeneration.The mechanism is associated with the down-regulation of TLR9/NF-κB signaling pathway expressions and function,the inhibition of inflammatory cytokines secretions,and the improvement of liver inflammatory microenviroment.
