ABSTRACT
OBJECTIVE：To study the effects and potential mechani sm of deoxyschizandrin on the proliferation ，migration and invasion of nasopharyngeal carcinoma cell HONE- 1. METHODS ：HONE-1 cell was set as cell model ，while CCK- 8 test，wound healing assay and Transwell chamber test were used to detect the proliferation ，migration and invasion ability changes of HONE- 1 cells after treatment with different concentrations [ 0（blank control ），10，20，40 μmol/L] of deoxyschizandrin. Computer molecular docking was performed to analyze the binding ability between deoxyschizandrin and Met protein. Western blotting assay was used to detect the relative protein expressions of p-Met ，p-PI3K，p-Akt，Bcl-2 and N-cadherin in cells. RESULTS ：Compared with blank control ，the proliferation ，migration and invasion ability of cells after treated with 10，20，40 μmol/L deoxyschizandrin were all decreased significantly （P＜0.05）. Results of molecular docking revealed that deoxyschizandrin could stably bind with the activity pocket of Met protein. Results of Western blotting assay demonstrated that compared with blank control ，10，20，40 μmol/L deoxyschizandrin all decreased the relative protein expressions of p-Met ，p-PI3K，p-Akt，Bcl-2 and N-cadherin in cells significantly（P＜0.05）. CONCLUSIONS ：Deoxyschizandrin can inhibit the proliferation ，migration and invasion of HONE- 1 cell via inhibiting the activation of Met/PI 3K/Akt signaling pathway.
ABSTRACT
OBJECTIVE:To investigate the preventive and therapeutic effect of Shuganning injection on alcoholic liver fibrosis (ALF) in model rats,and provide experimental basis for its clinical application for alcoholic liver disease. METHODS:50 rats were enrolled and intraperitoneally given mixed liquid of 60% alcohol-corn oil-pyrazole to reduce ALF model. Another 10 rats were enrolled and intraperitoneally given normal saline,as normal control group. After 16 weeks,survived model rats(n=40)were ran-domly divided into model group,positive control group(Anluo huaxian pill 0.75 g/kg,ig),Shuganning injection high-dose,medi-um-dose,low-dose groups(4.8,2.4,1.2 mL/kg,ip),8 in each group. Normal control group and model group were intraperitone-ally injected equal volume of normal saline (5 mL/kg),administration groups were given relevant medicines,once a day,for 8 weeks;and modeling was contiuously conducted at the same time. After administration,body mass of rats was weighed,and the levels of liver function indexes [aspartate aminotransferase(AST),alanine aminotransferase(ALT)] and liver fibrosis indexes [hyal-uronic acid(HA),laminin(LN),type Ⅲ procollagen(PⅢNP),type Ⅳ collagen(Ⅳ-C)] in serum of rats were detected. Liver index of rats was determined and pathological changes of liver tissue were observed. RESULTS:Compared with normal control group,body mass of rats in model group was significantly decreased(P<0.05);liver index,and liver function index,liver fibro-sis index levels in serum were significantly increased (P<0.05 or P<0.01). Liver tissue showed steatosis,hepatocyte vacuoliza-tion,a large number of fibrous tissue deposition around portal areas and other pathological changes. Compared with model group,above-mentioned changes were improved significantly in administration groups (P<0.05 or P<0.01). CONCLUSIONS:Shugan-ning injection can obviously improve liver tissue damage of model rats with ALF,showing certain preventive and therapeutic effect on alcoholic liver disease.
