title: [Effect of drugs for promoting blood circulation on blood lipids and inflammatory reaction of atherosclerotic plaques in ApoE gene deficiency mice].
abstract: OBJECTIVE
  To observe the effect of six common Chinese medicinal herbs for promoting blood circulation, including Radix Paeoniae rubra (I), Radix Salviae miltiorrhizae (II), Rhizoma Chuanxiong (III), Radix Notoginseng (IV), Semen Persicae (V) and wine steamed Radix et Rhizoma Rhei (VI), on blood lipids and inflammatory reaction of atherosclerotic plaques in ApoE gene deficiency mice.
  
  
  METHODS
  Ninety mice, 6 - 8 weeks old, were divided into 8 groups, the model group, the control group (treated with simvastatin) and the six treated groups treated with the above-mentioned 6 Chinese medicinal herbs respectively. All the mice were fed with the diet of western kind for 13 weeks until the mature atherosclerotic plaques formed in them. Then they were treated with respective drugs for another 13 weeks except those in the model group. All the mice were sacrificed at the end of experiment, their blood was collected for lipids determination, heart and aorta were taken out for determining the level of CD68 in root of aorta, as well as the expressions of monocyte chemotactic protein-1 (MCP-1) and tumor necrosis factor-a (TNF-a) by immunohistochemistry staining.
  
  
  RESULTS
  All the 6 Chinese herbs showed regulatory action on blood lipids. The positive expression of CD68 in the model group displayed the highest activity. As compared with the model group, the CD68 positive expressed cells in the control group and the groups treated with Chinese herbs II, III, and IV were lesser (P < 0.05), and the expression of inflammatory factors (MCP-1 and TNF-alpha) in atherosclerotic plaques was significantly lower in the control group and the group treated with Chinese herb VI (P < 0.05).
  
  
  CONCLUSIONS
  Chinese medicinal herbs tested in this study can interfere the maturing progress of atherosclerotic plaques and stabilize the plaques in ApoE deficiency mice, the mechanisms may relate to its actions in regulating lipids metabolism and inhibiting inflammatory reaction. Different Chinese medicinal herbs for activating blood circulation of conventional dosage might show difference in potency and acting links.
