[Protective effect of Ginseng Guipi Pill on liver injury in rats with spleen failing to control blood syndrome and its mechanism].

To investigate the therapeutic effect of Ginseng Guipi pill on rats with spleen failing to control blood syndrome and its effect on liver. Forty SPF male Sprague-Dawley rats were randomly divided into normal control group (=10) and experimental group (=30). For the first 42 days, the experimental group swam for 30 minutes every day, eating for one day and fasting for two days (diet disorder). On the 43rd to 72nd day, the rats were injected with low-molecular-weight heparin calcium to induce hemorrhage on the basis of exhaustion of swimming and diet disorder to construct a rat model of spleen failing to control blood syndrome. Those thirty rat that successfully established the model were randomly divided into 3 groups (=10), model control group (MD), natural rehabilitation group (NR) and Guipi Pill group (GP). On the 73rd to 103rd day, the MD group continued to apply factors (exhausted swimming, eating disorder, and injection of low-molecular-weight heparin calcium), the NR group and the GP group stopped applying the factors , the GP group was daily administered with Ginseng Guipi Pill solution (0.2 g/ml, 10 ml/(kg·d)) , and the NR group was given an equal dose of saline. After the 103 days, blood and liver samples were collected, and the serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil) and total protein (TP) content were detected, the number of red blood cells (RBC), hemoglobin (HGB) content and hematocrit (HCT) were detected, the expressions of IL-6 and TNF-α in serum were determined by ELISA kit, the levels of apoptosis-related proteins Bcl-2, Bax and Caspase3 in liver tissue were detected by Western blot. The expression levels of apoptosis-related proteins Bcl-2, Bax and Caspase3 mRNA in liver tissue were detected by real-time PCR. Compared with the control group, the serum levels of ALT, AST and TBil in the model group were increased significantly, while the serum level of TP was reduced significantly (＜0.01), the number of RBC, HGB content and HCT were decreased significantly (＜0.01), the expressions of IL-6 and TNF-α in serum were increased (＜0.05), the Bcl-2 protein and mRNA levels were reduced, Bax and Caspase3 protein and mRNA levels were increased significantly (＜0.01); Compared with the model group, the serum levels of ALT, AST and TBil were significantly lower in the natural rehabilitation group and the Guipi Pill group, the level of TP was increased significantly (＜0.01), the blood RBC, HGB and HCT were increased significantly (＜ 0.01), the expressions of IL-6 and TNF-α were decreased (＜0.05), the levels of Bcl-2 protein and mRNA were increased significantly, the Bax, Caspase3 protein and mRNA levels were decreased (＜0.05); Compared with the natural rehabilitation group, the serum levels of ALT, AST and TBil were reduced , and the TP content was increased significantly in the Guipi Pill group (＜ 0.01), the number of RBC was increased significantly in the Guipi Pill group (＜0.05), the levels of Bcl-2 protein and mRNA were increased (＜0.05),the level of Caspase3 protein was decreased (＜0.05), the expression of Bax mRNA was reduced significantly (＜0.05). Ginseng Guipi Pill has protective effect on liver injury in rats with spleen failing to control blood syndrome. The mechanism may be related to the inhibition the liver cell apoptosis and the release of pro-inflammatory cytokines.
