Objective To investigate the effects of Gynostemma Pentaphyllum on serum markers of liver fibrosis in cholesterol-induced non-alcoholic fatty liver disease (NAFLD) in rabbits. Methods Forty adult male white rabbits were randomly divided into a normal control group, a model group, a treatment group and a simvastatin group, with 10 rabbits in each group. NAFLD was induced with a high-cholesterol diet. After modeling, the rabbits in the treatment group were intragastrically administrated with Gynostemma Pentaphyllum 5 mg/(kg?d), the simvastatin group with simvastatin 5 mg/(kg?d), and the model and normal control groups with the equal volume of distilled water for 9 weeks. The serum levels of total cholesterol (TC) and triglyceride (TG), the serum inflammatory maker C-reactive protein (CRP), the serum markers of liver fibrosis such as hyaluronic acid and laminin (LN), and the TG level in the liver tissue were detected. Results Compared with the normal control group, the serum levels of TC (60.50 ± 9.77 mg/L vs.1.30 ± 0.44 mg/L), TG (1.72 ± 0.61 mmol/L vs. 0.85 ± 0.39 mmol/L), CRP (256.79 ± 30.78 mg/L vs. 8.71 ± 1.41 mg/L), HA (798.8 ± 69.4 ng/ml vs. 121.2 ± 6.8 ng/ml),LN (964.8 ± 62.8 ng/ml vs. 142.4 ± 12.2 ng/ml) in the model group were increased significantly (all P<0.01). Compared with the model group, the serum levels of TC (36.44 ± 6.57 mmol/L vs. 60.50 ± 9.77 mmol/L), TG (1.31 ± 0.39 mmol/L vs. 1.72 ± 0.61 mmol/L), CRP (68.77 ± 10.78 mg/L vs. 256.79 ± 30.78 mg/L), HA (420.8 ± 60.2 ng/ml vs. 798.8 ± 69.4 ng/ml), LN (449.8 ± 56.6 ng/ml vs. 964.8 ± 62.8 ng/ml) and the TG level in the liver tissue (0.52 ± 0.10 mmol/L vs. 0.77 ± 0.08 mmol/L) in the treatment group were decreased significantly (all P<0.01). The TG level in the liver tissue in the treatment group was significantly lower than that in the simvastatin group (0.52 ± 0.10 mmol/L vs. 0.59 ± 0.09 mmol/L;P<0.05). There were no significant difference in the serum levels of TC, TG,CRP,HA and LN between the treatment group and the simvastatin group (all P>0.05). Conclusions Gynostemma Pentaphyllum may regulate lipid metabolism, alleviate inflammation, and decrease serum markers of liver fibrosis, and might protect against liver fibrosis in rabbits with NAFLD.

Objective To obserVe the effect of gyPenoside on liPid Peroxidation and hePatic lesion in rats with tyPe 2 diabetes mellitus and nonalcohol fatty liVer disease. Methods Totally,65 SPF male SD rats were randomly diVided into blank control grouP (grouP N),NAFLD model grouP (grouP NM),and NAFLD with T2DM model grouP. The NAFLD with T2DM model grouP was further diVided into three subgrouPs:JH grouP,Perfused with 1 g·kg-1 ·d-1 GPS;JL grouP,Perfused with 0. 5 g·kg-1 ·d-1 GPS;model control grouP,Perfused with the same Volume of water. Blood sugar,triglycerides ( TG) ,total cholesterol ( TC) ,alanine aminotransferase ( ALT) ,asPart aminotransferase ( AST) ,adePonectin ( ADP) in the Plasma were measured. TG, malondialdehyde (MDA),and suPeroxide dismutase (SOD) in the liVer tissue were also tested. Results ADP leVel was (7. 46±1. 12),(3. 58±0. 98),(4. 89±1. 02),(4. 79±1. 01) and (4. 13±0. 89) ng·mL-1 in N,M,NM,JH and JL grouPs, resPectiVely. The ADP leVel was significantly higher in grouP JH and JL than in grouP M (P<0. 01),and significantly higher in grouP JH than in grouP JL (P<0. 05). MDA leVel was (2. 98±0. 09),(4. 22±0. 11),(3. 66±0. 10),(3. 72±0. 11),(3. 99±0. 13) nmol·mL_1 in N,M,NM,JH and JL grouPs,resPectiVely. The MDA leVel was significantly lower in grouP JH and JL than in grouP M (P<0. 01),and significantly lower in grouP JH than in grouP JL (P<0. 05). SOD leVel was (240. 8±17. 4), (149. 9±20. 6),(181. 6±19. 4),(209. 8±19. 2),(189. 4±18. 9) U·mL_1 in N,M,NM,JH,and JL grouPs,resPectiVely. SOD leVel was significantly higher in grouP JH and JL than in grouP M (P<0. 01),and significantly higher in grouP JH than in grouP JL (P<0. 05). TG leVel was (28. 98±1. 68),(214. 46±5. 44),(198. 46±6. 98),(142. 87±6. 64) and (164. 92±7. 56) mg·g-1 in N,M,NM,JH and JL grouPs,resPectiVely. TG leVel was significantly lower in grouP JH and JL than in grouP M ( P<0. 01),and significantly lower in grouP JH than in grouP JL (P<0. 05). ALT and AST were significantly lower in grouP JH and JL than in grouP M (P<0. 01),and significantly lower in grouP JH than in grouP JL (P<0. 05). Conclusion The liPid Peroxidation in the liVer of rats with T2DM comPlicated with NAFLD can be reduced by gyPenoside,and hePatic lesion may be alleViated through inhibition of liPid Peroxidation.
