| 摘 要： | Objective: To observe the effects of Xiongshao Capsule(芎芍胶囊, XSC) on anti-inflammatory properties of high-density lipoprotein(HDL), myeloperoxidase(MPO) and paraoxonase 1(PON1) in serum of atherosclerosis(AS) rabbit model and explore the anti-inflammatory protective effects of XSC on HDL. Methods: Sixty rabbits were randomized into the control, the model, XSC low-, medium-and high-dose(Rhizoma Chuanxiong + Radix Paeoniae rubra : 0.6+0.3, 1.2+0.6, 2.4+1.2 g·kg-1·day-1, respectively), and simvastatin(1 g·kg-1·day-1) groups. The model rabbits were fed with high-fat diet and respective drugs for 15 weeks. The blood and thoracic aortas samples were collected at the end of 15 weeks. The levels of serum MPO and PON1 as well as total cholesterol(TC) and free cholesterol(FC) in aorta wall cells were tested by enzyme linked immunosorbent assay. Results: TC and FC in the model group were significantly higher than those in the control group(P0.01). Compared with the model group, TC and FC in the XSC groups were significantly lower(P0.05 or P0.01), so was simvastatin group(P0.01). There was no significant difference in PON1 level between groups(P0.05), even between model and control groups(P0.05). The serum MPO level in the model group was significantly higher than that in the control group(P0.05), which was significantly lower in XSC groups as well as simvastatin group(P0.05 or P0.01), and no difference was found between XSC groups and simvastatin group(P0.05). Conclusions: XSC can reduce the serum MPO level in AS rabbits to protect the anti-inflammatory function of HDL, maintaining the normal lipid transport function. TC and FC levels in aorta cells decline, and this process initiated by XSC plays an anti-AS role.
