Active Components Formulation Developed from Fuzheng Huayu Recipe for Anti-Liver Fibrosis / 中国结合医学杂志

OBJECTIVE@#To screen the active components from Fuzheng Huayu Recipe (FZHY) and redesign a new recipe composed of the active components, and validate the effect of active components formulation from FZHY against liver fibrosis.@*METHODS@#Thirty-two components from FZHY were evaluated for their activities against liver fibrosis respectively, with 6 kinds of cell models in vitro, including oxidative stressed hepatocyte in L-02, hypoxia injured/proliferative hepatic sinusoidal endothelial cells in SK-HEP-1 and human hepatic sinusoidal endothelial cells (HHSEC), and activated hepatic stellate cell in LX-2. The comprehensive activity of each component against liver fibrosis was scored according to the role of original herbs in FZHY and cell functions in fibrogenesis. Totally 7 active components were selected and combined with equal proportion to form a novel active components formulation (ACF). The efficacy of ACF on liver fibrosis were evaluated on activation of LX-2 and proliferation of HHSEC in vitro and in liver fibrosis model mice induced by dimethylnitrosamine (DMN). Totally 72 mice were divided into 6 groups using a random number table, including normal, high-dose ACF control (20 µ mol/L × 7 components/kg body weight), model, low-, medium-, high-dose ACF groups (5, 10, 20 µ mol/L × 7 components/kg body weight, respectively). Hematoxylin eosin and Sirius red stainings were used to observe inflammation and fibrosis change of liver tissue; scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were utilized to observe the effect of ACF on ultrastructure of hepatic sinusoids.@*RESULTS@#Fifteen components from FZHY showed higher scores for their activity on against liver fibrosis. Among them, 7 components including tanshinone II A, salvianolic acid B, cordycepin, amygdalin, quercetin, protopanaxatriol, and schizandrin B were recombined with equal proportions to form ACF. ACF at 1,2, 4 µ mol/L showed strong inhibitory effects on activation of LX-2 and proliferation of HHSEC in vitro (all P<0.01). Compared with the model group, ACF attenuated liver collagen deposition, improved sinusoidal capillarization in a dose-dependent manner (all P<0.05).@*CONCLUSION@#ACF exerts a satisfactory effect against experimental liver fibrosis and attenuates sinusoidal capillarization, which warrant a further research and development for herbal components formulation on liver fibrosis.

Protective effect of Tanreqing injection on acute hepatic injury induced by CCl4 in rats / 中国中药杂志

<p><b>OBJECTIVE</b>To observe the protective effect of Tanreqing injection(TRQ) on carbon tetrachloride-induced acute hepatic injury in rats.</p><p><b>METHOD</b>Rats were randomly divided into the normal group and the model group, and injected subcutaneously with 100% CCl4 5 mL x kg(-1) to establish the single CCl4 infection model, in order to observe the changes in rat liver injury after 3 h and 6 h. Subsequently, the multiple CCl4 infection liver injury model was reproduced by subcutaneously injecting 100% CCl4 (5 mL x kg(-1)), 50% CCl4 olive oil solution (2 mL x kg(-1)) and then 20% CCl4 olive oil solution (2 mL x kg(-1)). At 6 h after the first CCl4 injection, the rats were divided into six groups: the model group, the control group, the diammonium glycyrrhizinate-treated group, and TRQ high, middle and low dose groups. They were injected through caudal veins, while a normal control group was set up. Their weight and liver-body ratio were observed. Hepatic inflammation was observed with HE staining. Assay kits were adopted to detect ALT, AST, T. Bil, D. Bil, CHE, TBA, gamma-GT and Alb.</p><p><b>RESULT</b>According to the single injection model, serum AST and T. Bil of model rats were obviously increased at 6 h after single subcutaneous injection of CCl4, with disordered lobular structure in liver tissues, notable swollen liver cells and remarkable liver injury. According to the results of the multiple injection pharmacological experiment, compared with the normal group, the model group had higher serum ALT, AST, and gamma-GT activities (P < 0. 05), TBA and T. Bil contents (P < 0.05) and lower CHE activity (P < 0.05). HE staining showed disorganized lobular structure in liver tissues and notable ballooning degeneration in liver cells. Compared with the model group, TRQ high and middle dose groups and the diammonium glycyrrhizinate-treated group showed significant charges in serum liver function and inflammation in liver cells. Specifically, TRQ high and middle dose groups were superior to the diammonium glycyrrhizinate-treated group.</p><p><b>CONCLUSION</b>Tanreqing injection has significant protective effect on CCl4-induced acute hepatic injury in rats.</p>
