The present study was designed to investigate the capacity of human peripheral blood monocytes to express MCP-1 and effects of native very low density lipoprotein (VLDL) and oxidized VLDL(OX-VLDL) on the expression. The total RNA was extracted from cultured monocytes, which were exposed to VLDL and OX-VLDL, and the media conditioned by monocytes were collected. MCP-1 mRNA expression was examined by Northern blot analysis. MCP-1 protein in conditioned media was determined by using sandwich ELISA. The results showed that monocytes can express MCP-1 after a 24 h incubation at 37℃,and the expression was markedly increased by a exposure to OX-VLDL, whereas the expression was slightly increased when exposed to VLDL. It suggests that the capacity of monocytes to produce MCP-1 that recruits and activates circulating monocytes may be of considerable importance in atherogenesis, and oxidation of VLDL enhances its potential to promote atherogenesis.展开更多
Objective:To research the anti-inflammatory and antioxidation effect of atorvastatin and probucol joint therapy on patients with acute coronary syndrome.Methods:228 patients with acute coronary syndrome were enrolled ...Objective:To research the anti-inflammatory and antioxidation effect of atorvastatin and probucol joint therapy on patients with acute coronary syndrome.Methods:228 patients with acute coronary syndrome were enrolled and randomized to atorvastatin group(atorvastatin 10 mg/d,n=120)and joint therapy group(atorvastatin 10 mg/d and probucol 0.25 g,2/d,n=108).The serum total cholesterol,low density lipoprotein cholesterol,hs-CRP and oxLDL level were measured before and 1 month after the therapy.Results:The indexes were no difference between the two groups before the therapy but significant difference 1 month after the therapy.Conclusion:Compare with atorvastatin alone,the joint therapy with probucol can give better anti-inflammatory and antioxidation effect and than better prognosis.展开更多
