METHODS: Crush injury was produced in SD rats,the serum levels of cardiac enzyme and cardiac troponin I,plasma levels of ANP and ET-1 were studied by automated biochemical analyzer,automated chemiluminescence assay and radioimmunoassay. RESULTS: The plasma ET-1 level was much lower ,the levels of plasma ANP and serum cardiac enzyme and cTnI were much higher after crush injury than those of the control group( P

AIM: To explore the role of activation and apoptosis of splenic lymphocytes in the development of viral myocarditis (VMC). METHODS: Apotosis and MHC II antigen of splenic lymphocytes were detected in the VMC group (VMC, death, 8 cases) and control group (non-cardiac death, 4 cases) with TUNEL and immunohistochemistry methods.RESULTS: Compared with the control group, the increased expression of MHC II antigen and apoptosis were found in the splenic lymphocytes in the VMC group. CONCLUSION: These results suggest that the abnormality of the apoptosis/activation of splenic lymphocytes may be involved in the pathogenesis of VMC.

Object To study chemical constituents of the root of Isatis indigotica Fort Methods The powdered plant material was percolated with 95% ethanol, the percolate was extracted with different solvents, the extract was subject to chromatography on silica gel column and macroporous resin column. The compounds were identitfied by their physicochemical properties and spectral data (MS, 1HNMR, 13 CNMR, UV and IR) Results Two compounds were obtained from the ethanol extracts of the plant root They are 3 (2′ hydroxyphenyl) 4(3H) quinazolinone and isaindigodione respectively Conclusion The two compounds were obtained from I. indigotica for the first time

Objective To compare the lipid lowing effect and the clinical safety between intensive therapy with Chinese medicine Zhihitai and atorvastntin in patients with moderate and high risk of atherosclerosis. Methods All the patients were randomly divided in to a Zhibitai group (n = 85) receiving 480 mg of Zhibitai orally twice a day or an atorvastatin group (n = 84) receiving 10 mg atorvastatin orally once daily. Blood lipoproteins, myocardial enzymes, fiver and renal function were measured before treatment and at the fourth and eighth week after therapy , while high sensitive creactive protein (hs-CRP), P-selectin, matrix-metall proteinase-9 (MMP-9) and soluble intercellular adhering molecule-1 (SICAM-1) were detected before treatment and eighth week after therapy in all patients. Results TC and LDL-C were significantly decreased while HDL-C was increased in both groups after 4 and 8 weeks treatment (P < 0. 05). TG was decreased in Zhibitai group after 4 and 8 weeks of treatment, but it was decreased in atorvastatin group only after 8 weeks of treatment. Inflammatory factors such as hs-CRP, P-selectin, MMP-9, SICAM-1 were decreased significantly (all P < 0. 01), but there was no significant difference between the two groups. There were no difference in liver and kidney function, myocardial enzymes and incidence of muscle-ache and digestive system side reaction. ConclusionsBesides the lipoprotein disorder, inflammatory factors in patients with moderate and high risk of atherosclerosis could be regulated with intensive therapy of Zhibitai. Most importantly, it is safe to use Zhibitai clinically.

Objective To examine the effects and mechanisms of simvastatin and fenofibrate, and combination of the two drugs on the expression of apolipoprotein M (apoM). Methods The male C57BL/6N mice ( n =32) were random divided into four groups, including control group (with no special treatment), statin group (with simvastatin [10mg/( kg · d) for 4 weeks], fibrate group (with fenofibrate [100mg/( kg · d) for 4 weeks] and combination group ( with simvastatin [10mg/( kg· d)] and fenofibrate [100mg/( kg · d) for 4 weeks]. The levels of apoMmRNA and protein, hepatic nuclear factor (HNF-1α)mRNA, liver X receptor-α (LXRα) mRNA in mouse liver were measured. Results Both of simvastatin and fenofibrate can increase the expression of apolipoprotein M ( 1.97 ± 0. 04,2. 02 ± 0. 02 ) and HNF-1αmRNA ( 1.74 ± 0. 05,1.71 ± 0. 04). Combination group obtained more effects than either single agent ( P ＜ 0. 05 ). Simvastatin could decrease the expression of LXRα mRNA ( 1.00 ± 0. 02 ) ( P ＜ 0. 05 ). Fenofibrate could increase the expression of LXRα mRNA(2. 80 ±0. 04) ( P ＜0. 05). No significant difference in LXRα expression was seen between combination( 1.56 ±0. 03 ) and control group( 1.53 ±0. 03 )( P ＞0. 05). Conclusions Simvastatin and fenofibrate can increase apoM expression. Treatment with combination of the two drugs is more effective, and the mechanism might be related to the regulation of HNF-1α and LXRα.

Objective To investigate the value of serum pentraxins-3 (PTX-3) together with triglyceride (TG)/high-density lipoprotein cholesterol (HDL-C) as predictor risk factors of future acute coronary syndrome(ACS). Methods One hundred and seventy-one cases of selective coronary angiography from July 2008 to December 2009 were collected and analyzed. According to the situation on admission and coronary angiography, patients were divided into three groups: normal control group (25 cases), stable angina pectoris (SAP) group (23 cases) and ACS group (123 cases). Fasting venous blood was extracted for measuring serum PTX-3 and lipids (TG, HDL-C) in the next morning, and the statistical significanc was analyzed. Results The level of serum PTX-3 and the ratio of TG to HDL-C in ACS group [(6.39 ± 3.01)μ g/L, 2.38 ± 2.00] were significantly higher than those in SAP group[(3.87 ± 2.05 ) μ g/L, 1.70 ± 1.01] and normal control group [(2.90 ± 1.94)μg/L,0.95 ±0.35] (P ＜0.01 or ＜0.05). Conclusion Increased serum PTX-3 levels and ratio of TG to HDL-C in patients are closely related with ACS, both of which increase the accuracy of early diagnosis of ACS.
