Effect of combined therapy of shenmai and compound danshen injection on myocardial reperfusion injury after percutaneous coronary intervention in patients with acute myocardial infarction / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To explore the effect of combined therapy of shenmai and compound danshen injection (SM-DS) on myocardial reperfusion injury after percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI).</p><p><b>METHODS</b>Thirty-eight AMI patients who received PCI were randomly divided into two groups, the 19 patients in the treated group were treated with SM-DS before and after PCI. Serum levels of malondialdehyde (MDA), superoxide dismutase (SOD), interleukin 6 (IL-6) and tumor necrosis factor alpha (TNF-alpha) in patients' venous blood were measured at different time-points, and the integrated left ventricular ejection isometric index (Tei) was determined by echocardiogram.</p><p><b>RESULTS</b>As compared with before operation in the treated group, MDA was higher and SOD was lower at 2 hrs, 24 hrs after operation (P < 0.05); IL-6 and TNF-alpha were significantly lower at 24 hrs, 48 hrs and 1 week (P < 0.05, P < 0.01) and the Tei began to be improved at 24 hrs (P < 0.05) and significantly improved at 1 week after operation (P < 0.01). While in the control group, MDA was higher and SOD was obviously lower at 2 hrs and 24 hrs (P < 0.01); lowering of IL-6 and TNF-alpha appeared at 1 week (P < 0.05) and improving of Tei index revealed 1 week after operation respectively (P < 0.05). Comparison between the two groups showed significant difference in levels of MDA and SOD at 2 hrs and 24 hrs (P < 0.01); significant difference in levels of IL-6, TNF-alpha at 24 hrs, 48 hrs and 1 week; and in Tei index at 24 hrs and 1 week after operation (P <0.05).</p><p><b>CONCLUSION</b>SM-DS could reduce the myocardial reperfusion injury in patients with AMI after PCI.</p>

Change of peripheral blood monocytes derived macrophage scavenger receptors activity in patients with coronary heart disease, and the intervention effect of ginkgo biloba extract / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To observe the activity of peripheral blood monocytes (PBMs) derived macrophage scavenger receptors (MSR) and changes of serum inflammatory factor in peripheral blood in patients with coronary heart disease (CHD), and to evaluate the effect of Ginkgo biloba extract (GBE) on the MSR activity, to explore the relationship between inflammatory factor and scavenger receptors activity as well as the possible mechanism of GBE in stabilizing the atheromatous plaque.</p><p><b>METHODS</b>Ninety-seven CHD patients with normal blood lipids were classified into the stable angina group, the unstable angina group and the acute myocardial infarction group, and 29 healthy persons were taken as control. Levels of C-reactive protein (CRP), soluble intercellular adhesion molecule-1 (sICAM-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) in all subjects were determined. And their PBMs were isolated, cultured in vitro, and transferred into macrophage to observe the effect of GBE on the expression of scavenger receptors.</p><p><b>RESULTS</b>The levels of MSR activity, CRP, sICAM-1 and sVCAM-1 in patients with acute myocardial infarction > unstable angina > stable angina > control.</p><p><b>CONCLUSION</b>GBE could down-regulate the MSR activity in CHD patients, which was positively correlated with levels of CRP, sICAM-1 and sVCAM-1. MSR activity could be taken as a monitoring criteria for active degree of vulnerable atherosclerosis plaque. GBE has the effect of suppressing MSR activity.</p>
