The arterial thrombosis model induced by ferric chloride(FeC l3) oxidation and the venous thrombosis model induced by inferior vena cava ligation were established to evaluate the antithrombotic potential of XECG. Our results indicated that XECG significantly prolonged the time to occlusion, activated partial thromboplastin time(APTT), and prothrombin time(PT), and markedly inhibited adenosine diphosphate(ADP)-induced platelet aggregation in the 20% Fe Cl3-induced arterial thrombosis model. The superoxide dismutase(SOD) activity was significantly increased and the levels of malondialdehyde(MDA) and nitric oxide(NO) were dramatically decreased in the plasma of arterial thrombosis rats after XECG treatment for 12 days. Furthermore, XECG markedly reduced the weight of thrombus formed by inferior vena cava ligation. Additionally, XECG exhibited 2,2-diphenyl-1-picrylhydrazyl(DPPH) free radical scavenging activity and protective effect on mitochondrial lipid peroxidation. In summary, XECG played an important role in the prevention of thrombosis through interacting with multiple targets, including inhibition of platelet aggregation and coagulation and repression of oxidative stress. The ECG-guided methodology was validated as a feasible tool in TCM research.展开更多

Methods ECGS consisted of Panax notoginsen saponion (PNS), hydroxysafflor yellow A, and ferulic acid plus volatile oil of Ligusticum chuanxiong, which was based on the active ingredients and their ratios in SXT. We compared the anti-inflammatory actions of ECGS and SXT using the xylene-induced edema model and the carrageenan-induced edema model, as well as the analgesic activity of them using the acetic acid-induced writhing model. Moreover, cultured macrophages were incubated with media containing serum isolated from SXT-, ECGS-, or every component of ECGS-treated rats, to compare the depress effects on lipopolysaccharide (LPS)-stimulated NO production and inducible nitric oxide synthase (iNOS) expression. Results ECGS and SXT had equivalent anti-inflammatory actions and analgesic effects at an equipotent dosage in a dose-dependent manner. The drug-containing media could inhibit the LPS-stimulated NO production and iNOS expression in cultured macrophages. A 2 × 2 × 2 ANOVA revealed that three effective components could produce synergistic effect on the inhibition of NO production, and PNS was the capital component. Conclusion ECGS and SXT display an equivalent anti-inflammatory effect, and the formula follows traditional Chinese medicine compatibility principle, which shows obvious formulary rationality.展开更多
