ABSTRACT
Objective:To observe therapeutic effect of maleic acid levamlodipine (amlodipine) on inflammatory fac‐tor levels in patients with essential hypertension (EH) .Methods :According to random number table method ,a to‐tal of 84 EH patients were randomly and equally divided into nifedipine group (received nifedipine treatment ) and amlodipine group (received maleic acid levamlodipine treatment ) ,both groups were treated for 12 weeks .Blood pressure ,serum levels of tumor necrosis factor α(TNF‐α) ,interleukin‐6 (IL‐6) and high sensitive C reactive protein (hsCRP) were measured and compared between two groups before and after treatment .Results:Before treatment , there were no significant difference in blood pressure ,serum levels of TNF‐α,IL‐6 and hsCRP between two groups , P>0.05;after treatment ,all above indexes significantly reduced in both groups compared with before treatment ,P<0. 01 all .Compared with nifedipine group ,there were significant reductions in systolic blood pressure [ (136. 9 ± 13.4) mmHg vs . (128.3 ± 12.5) mmHg] ,diastolic blood pressure [ (88.4 ± 7.1) mmHg vs . (82.7 ± 6.8) mm‐Hg] ,serum levels of TNF‐α [ (10.85 ± 2.56) ng/L vs . (8.61 ± 2.37) ng/L] ,IL‐6 [ (18.92 ± 4.61) ng/L vs . (13.73 ± 4.18) ng/L] and hsCRP [ (7.95 ± 2.38) mg/L vs . (5.89 ± 2.24) mg/L] in amlodipine group , P<0.01 all .Conclusion:Amlodipine can more significantly reduce levels of TNF‐α,IL‐6 and hsCRP ,inhibit inflammatory reaction than those of nifedipine and contribute to blood pressure control in patients with essential hypertension .
ABSTRACT
Objective To evaluate the diagnostic value of H-FABP、cTnI and CK-MB for early detection of acute myocardial infarction(AMI).Methods 20 New-Zealand rabbits were randomly divided into 2 groups:surgery group(MI group,n=12) and sham surgery group(control group,n=8).MI group was opened the chests and the anterior descending branches of the left coronary arteries(LAD) were ligated;in sham surgery group the sutures were passed under the LADs without ligation.Blood sampled before surgery and 1,2,3,4,6,8,10 and 24 h after surgery.H-FABP,cTnI and CK-MB were measured by ELISA respectively at the same time.Results The plasma concentrations of H-FABP 1 hour after surgery showed statistical difference between MI group and sham surgery group(P
ABSTRACT
Objective To investigate the serum of soluble CD40 ligand(sCD40L) in coronary heart disease and its relationship with serum lipid levels and the extent of coronary stenosis,whether upregulation of CD40L system is related to stability of atherosclerotic plaque in patients with acute coronary syndrome.Methods Enzyme-linked immunosorbent assay(ELISA) was used to measure the level of sCD40L in 64 patients with coronary heart disease(18 with acute myocardial infarction,19 with unstable angina pectoris and the other 27 with stable angina pectoris) and 20 matched healthy controls.Coronary stenosis of 29 patients were assessed by angiographic coronary stenosis morphology.Results sCD40L level was significantly higher in patients with acute coronary syndrome(ACS)((19.8?3.0)、(19.6?4.3)ng/mL in acute myocardial infarction and unstable angina pectoris group,respectively)than that of those with stable coronary heart disease and that of controls((8.3?3.2)ng/mL and(2.6?1.9)ng/mL,respectively P
ABSTRACT
Objective To investigate the short and longterm effect of the treatment on acute coronary syndrome(ACS) with percutaneous coronary angioplasty and stenting.Methods 65 patients suffering from ACS were treated with angiography to illuminate the features of lesions and proceeded with percutaneous coronary angioplasty and stenting when the angina was not completed controlled with internal medicine.All patients were treated with a new anti-thrombotic regimen,including aspirin,ticlopidine or clopidogrel, and low-molecular-weight heparin.Results The rates of success for patients and lesions were 96.9% and 82.7% respectively.One patient died without myocardial infarction or emergency bypass surgery.56 patients had no symptom of angina after procedure,and 5 patients had non-typical chest pain which disappeared within 2~3 days.During the 3~54 month follow-up,one patient died,one patient developed myocardial infarction and 4 patients underwent target vessel revascularization(repeated angioplasty 2 and bypass surgery 2).Conclusions With the widespread use of aspirin-ticlopidine-low molecular heparin regimen,ACS patients can undergo PTCA and stenting with high success rate,excellent immediate efficacy and long-term efficacy.
