Methods:TCMSP database and literature mining were used to analyze the main effective components in XTH, and the targets were predicted by Swiss Target Prediction server according to AS mechanism. The potential targets were introduced into the FunRich database for target annotation and analysis, the path analysis was finally performed based on the FunRich databases. To determine the mechanism of action of XTH. Results:A total of 316 compounds, 117 targets, and 290 signaling pathways were identified. And 16 effective compounds, 39 common targets, and 43 pathways were associated with AS. Conclusions:The results showed that the flavonoids, phenols, organic acids and terpenoids of XTH could participate in the process of lipid metabolism, angiogenesis, oxidation, inflammation, endocrine metabolism, cell proliferation and apoptosis, It was further found that they could play the role of anti-Atherosclerosis through multi-component, multi-target, and multi-channel synergistically.展开更多

Methods Male 8-week-old apoE^-/- mice fed a diet containing 1.25% cholesterol （wt/wt） were divided into pravastatin group administered with pravastatin （80 mg. kg ^-1· d^-1 ） and atherosclerosis group administered with PBS; and male 8-week-old C57BL/6J mice fed a normal diet were as control group （ n = 12 ）. In thoracoabdominal aortas of mice, levels of Malondialdehyde （ MDA ） and activities of superoxide dismutase （ SOD ） were measured and expression of phosphorylated p38 MAPK （ p-p38 MAPK） and phosphorylated signal transducer and activator of transcr（ption 1 （pSTAT1） were examined by Western blotting. Results After eight weeks, atherosclerosis in aortic root was significantly prevented by pravastatin. In aortic atherosclerosis lesion, the level of MDA was significantly reduced; adversely the activity, of SOD was increased. Expressions of p-p38 MAPK and pSTAT1 were significantly decreased in aortic atherosclerosis lesion. Conclusion Our results suggests that anti-oxidative mechanisms of pravastatin preventing aortic atherosclerosis may partially depend on modulating p38 MAPK signal pathway.展开更多
