ABSTRACT
AIM:To investigate the effect of Fufang Zhenzhu Tiaozhi capsule(FTZ)on serum lipids and in-flammatory factors in rabbits with abdorminal aortic restenosis after balloon angioplasty.METHODS: New Zealand white rabbits(n=30)were divided into 5 groups.Except blank control group,the rabbits in other groups were used to establish abdominal aortic endothelium exfoliative vascular stenosis model.After 4 weeks of high-fat diet feeding,the animals in rest-enosis model group and drug treatment groups underwent percutaneous balloon dilatation in the stenosis.The angiographic stenosis was analyzed by a two-dimensional quantitative coronary angiography workstation with a digital subtraction X -ray machine.Blood samples were taken during angiography and the profiles of serum lipids and cytokines were measured.The expression of nuclear factor-κB(NF-κB)in the blood vessels was determined by immunohistochemistry.RESULTS:An-giography confirmed that the rates of area stenosis and diameter stenosis were significantly decreased in treatment groups compared with restenosis model group(P<0.01).Compared with restenosis model group,the serum lipid profiles and cy-tokine concentrations in drug treatment groups were significantly decreased(P<0.05).Immunohistochemistry showed the expression of NF-κB in restenosis model group was significantly higher than that in blank control group and drug treatment groups(P<0.05).CONCLUSION: FTZ significantly reduces the blood lipids and inflammatory factors in abdominal aortic restenosis model,and the anti-inflammatory effect may be related to the regulation of NF-κB pathway to inhibit the production of various inflammatory factors.
