Abstract： Objective To investigate the serum retinol - binding protein 4 ( RBP 4 ) of coronary heart disease (CHD)patients and evaluate whether plasma macrophage migration inhibitory factor were associated with CHD. Methods Sixty -four patients with CHD were divided into the acute myocardial infarction (AMI) group ( n = 10), the unstable angina pectoris (UAP) group ( n = 42) and the stable angina pectoris(SAP) ( n = 12),21 normal subjests without CHD diagnosed by CAG served as the control group. The serum level of RBP4 measured by enzyme linked immune sorbent assay (ELISA). Results The serum level of RBP4 were higher in AMI and UAP group thai in SAP group and control group ( P ＜ 0. 05 ). The mean level of RBP4 in SAP group was not differently significantly, compared with that in control ( P ＞ 0. 05 ) ;The mean level of in single, double and three vessel lesion group were higher than that in control group (P ＜0. 05 ),but the serum levels of RBP4 among single, double and three were not significant different ( P ＞ 0. 05).Conclusions RBP4 may act as one of vulnerable plaques,we can take active to stabilize vulnerable plaques and decrease the occurrence of cardiac events,but may not reflect the severity of artery stenosis.     

The changes of Hs-CRP and WBC count after percutaneous coronary intervention in different types of coronary heart diseases

Objective: To investigate the regulation of High sensitive C-reactive protein(Hs-CRP) and WBC count in patients with coronary heart disease(CHD) by percutaneous transluminal intervention(PCI) and to discuss the mechanism of inflammatory reaction after coronary stenting. Methods:127 patients who received successful percutaneous transluminal coronary stenting, were divided into groups of stable angina(SAP), unstable angina(UAP), and acute myocardial infarction(AMI) according to their clinical types. Another 41 stable angina patients with more than 7o% of coronary artery tenosis who did not receive PCI served as control. Serum Hs-CRP levels and WBC count were determined before intervention, 3 days and 7 days post PCI and the data were analyzed statistically by t-test. Results: There showed no difference in clinical baseline characteristics between groups. The serum Hs-CRP level and WBC count was gradually raised in the UAP and AMI group(how about SAP group, and had no difference in CAG group and SAP group). After PCI serum Hs-CRP levels and WBC counts were significantly higher in the SAP group than in the coronary angiography group(CAG) at 3 days and had no difference at 7 days. In the UAP and AMI group, the serum Hs-CRP level at 3 days and 7 days declined obviously, however serum WBC count did not decrease apparently. Conclusion: The serum Hs-CRP level and WBC count elevate transiently after PCI. There are different inflammatory reactions in different types of coronary heart diseases after coronary stenting procedure.

Abstract： Objective To investigate the possible relationship between the serum LP(a) and coronary artery changes in patients with coronary heart disease (CHD). Methods Coronary angiography (CAG) was performed in 323 patients. The patients were divided into CHD group and control group. The serum levels of lipids were measured. According to the coronary number of stenosis, CHD group was further divided into 1-vessel group, 2-vessel group and 3-vessel group according to the degree of coronary lesion, CHD group was further divided into light stenosis group, moderate stenosis group and severe stenosis group. Results The levels of total cholesterol (TC),LP(a),LDL-C and triglyceride (TG) in CHD patients were significant higher than those in the control group. The serum levels of TC,LP(a) and LDL-C were significantly related to CHD (P<0.01).The serum levels of TC,LP(a) and LDL-C were higher in the 2-vessel group and 3-vessel group than that in the control group and 1-vessel group (P<0.01).The serum levels of TC,LP(a) and LDL-C were higher in the moderate stenosis group, severe stenosis group than that in the control group and light stenosis group(P<0.01). Conclusions The increasing of TC, LP(a) and LDL-C are associated with the stenosis degrees and lesion degrees of coronary artery in patients with CHD which indicated that TC,LP(a) and LDL-C have clinical significance for evaluating the change of degree of coronary artery lesion.     

Levels of soluble adhesion molecules in patients with various clinical presentations of coronary atherosclerosis

Background Adhesion molecules play an important role in the development and progression of coronary atherosclerosis. The aim of this study was to compare concentrations of soluble forms of adhesion molecules in patients with different clinical presentations of coronary artery disease （CAD）.Methods One hundred and twenty-eight patients with CAD were divided into three groups; the first group was acute myocardial infarction group （AMI group, n=45）, the second group was unstable angina pectoris group （UAP group, n=48）,the third group was stable angina pectoris group （SAP group, n=35）. We compared them with patients with normal coronary arteries （control group, n=31）. The serum levels of vascular cell adhesion molecule （VCAM-1）, intercellular adhesion molecule-1 （ICAM-1）, E-selectin and P-selectin were measured in all subjects.Results The serum level of VCAM-1 in the AMI group was significantly higher than in the UAP, SAP and control groups （P 〈0.01）. The level in the UAP group was significantly higher than the SAP group and control group （P 〈0.01） and the level in the SAP group was significantly higher than in the control group （P 〈0.01）. The serum ICAM-1 level was significantly elevated in the AMI, UAP and SAP groups as compared to the control group （P 〈0.01）. The levels of serum E-selectin and P-selectin in the AMI and UAP groups were significantly higher than in the SAP and control groups （P〈0.01）.Conclusions Increased levels of VCAM-1 and ICAM-1, E-selectin and P-selectin, as markers of inflammation, showed the importance of inflammatory processes in the development of atherosclerosis and clinical expression of CAD. Soluble ICAM-1, VCAM-1, E-selectin and P-selectin concentrations are useful indicators of the presence of atherosclerosis and the severity of CAD clinical presentation.     

Relation of coronary vulnerable plaque instability to serum levels of C-reactive protein and B-type natriuretic peptide in ACS.

Objective To explore the relationship between coronary vulnerable plaque instability and serum C-reactive protein(CRP) , B-type natriuretic peptide(BNP) levels in 85 patients with coronary heart disease. Methods Eighty-five patients( aged 63±16,M= 52 ) were divided into two groups.The control group was 28 patients with stable angina pectoris (SAP). The study group was 57 patients with acute coronary syndrome (ACS) .which were further divided into 21 patients with non ST elevated myocardial infarction (NSTEMI) and 36 patients with unstable angina pectoris (UAP). Plasma BNP and CRP were measured as well as coronary angiography made for all 85 patients. Plaques of coronary culprit arteries were classified as I -III three types according to Ambrose classification. Results (1). BNP and CRP levels of NSTEMI and UAP groups were significant higher than in SAP group. (2).The levels of BNP and CRP correlated with Ambrose classification, especially positively with Ambrose II type ,but no relation with coronary narosis. (3). The levels of BNP was much higher in patients of left anterior descending or multiple coronary artery diseases .(4). The Plaques of coronary culprit arteries in high risk of NSTEMI and UAP patients were mostly Ambrose II or III type. Conclusions The prevalence of higher levels of plasma BNP and CRP in patients with ACS ,when compared with those of SAP, was associated with the instability of coronary vulnerable plaques (ie, Ambrose II type). The level of BNP was much higher in patients of left anterior descending or multiple complicated coronary diseases. So, BNP and CRP are not only markers of vulnerable plaques, but also indicators of ACS prognosis.
