比较两组治疗前后血脂水平及颈动脉内中膜厚度，颈动脉斑块面积的变化。
The change of the serum lipid, carotid intima-media thickness and the size of the plaques were compared between the two groups.
颈动脉IMT变薄及斑块面积减少，与对照组比较差异均有显著性（P<0.05～0.01）。
The IMT of carotid artery and the area of carotid atherosclerosis plaque significantly reduced compared with control group ( P<0.01~0.05).
观察两组治疗前后中医临床证候、血压水平、血脂、颈动脉IMT、斑块面积和体积的变化并进行安全性评价等。
The changes of TCM syndromes, blood pressure, blood fat, carotid IMT, and area and volume of plaque were observed in two groups before and after the treatment, and the safety was reviewed.
结果：消瘀片可使软斑和不均匀斑的斑块面积明显缩小；脂质代谢和颈动脉血流参数明显改善。
Results: Areas of soft and heterogeneous plaques obviously reduce and blood flow parameters of carotid artery were obviously improved as well.
