Objective To explore the effect of angiotensin Ⅱ antagonist on left ventricular hypertrophy(LVH) and insulin resistance in elderly patients with diabetes mellitus and hypertension. Methods One hundred and twenty elderly patients with diabetes mellitus and essential hypertension with LVH by echocardiography entered the study. Patients were randomized into the telmisartan (80～160 mg/d) group or perindopril (4～8 mg /d) group. After treatment of telmisartan or perindopril,patients were followed-up for 8 months.Plasma sample was collected from each patient before and after treatment of telmisartan or perindopril,respectively.Then plasma levels of cholesterol,fasting plasma glucose(FPG), insulin and Homeostasis Model Assessment Insulin Resistance (HOMA-IR) were investigated.The echocardiography before and after 8 months of treatment with telmisartan or perindopril were also examined. Results Data were analyzed and showed that: (1)After 8 months of treatment with telmisartan or perindopril, blood pressure was reduced from 159/101 to 142/89 mm Hg(P

ObjectiveTo investigate the correlation of lipids and lipoproteins with cardiac function in patients with coronary heart disease (CHD).MethodsParameters of blood pressure, serum lipids and lipoproteins, clinical features, radionuclide ventriculographic and coronary angiographic findings were analyzed retrospectively in 584 CHD patients treated with standard treatment.ResultsThe left cardiac dysfunction of CHD patients was correlative positively with age, systolic blood pressure (SBP), diastolic blood pressure (DBP), blood glucose, body mass index (BMI), smoking, total cholesterol(TC) and low density lipoprotein cholesterol(LDL-ch) significantly(P<0.001), not correlative with high density lipoprotein-cholesterol (HDL-ch). The left ventricular ejection fraction (LVEF) and left ventricular peak filling rate (LVPFR) were decreased along with the levels of TC and LDL-ch increased (P<0.05～0.01).ConclusionTC and LDL-ch are positively correlative with left cardiac dysfunction in CHD patients. In order to reduce cardiac damage of CHD associated with hyperlipoidemia, more attention should be paid to the amelioration of coronary arteriosclerosis and the reduction of serum lipids and lipoproteins.

Objective To investigate the relationship between blood glucose levels and severity of coronary stenosis in hypertensive patients. Methods Blood pressure, fasting plasma glucose, 2 h plasma glucose, clinical features and coronary angiographic findings were analyzed retrospectively in 540 patients with essential hypertension. Acoording 2 h plasma glucose, patients were stratified into three group: group 1: 2h plasma glucose

ObjectiveTo observe the effect of telmisartan on plasma levels of inflammatory cytokine in coronary artery disease (CAD) patients complicated with diabetes mellitus and hypertension after percutaneous coronary intervention.MethodsFifty CAD patients who just had undertook angioplasty and implanted stents were randomly divided into two groups, the test group (telmisartan group, n=25) and control group (perindopril group, n=25). After treatment, patients were followed-up for 6 months; plasma samples were collected from each patient before and after percutaneous coronary intervention. Then plasma levels of C-reactive protein (CRP), monocyte chemoattractant protein-1 (MCP-1) were measured by enzyme-linked immunoassay. The changes of cholesterol, fasting plasma glucose (FPG), insulin and insulin resistance index (IRI) were observed.ResultsAt the end of 6 months, plasma levels of CRP and MCP-1 of patients in the test group significantly declined (P<0.01), and showing a inversely correlation with FPG (P<0.01), and FPG, insulin and IRI also declined. In the control group, only CRP and MCP-1 declined (P<0.05). Meanwhile, the frequency of cardiovascular events in test group was significantly lower than that in the control group.ConclusionTelmisartan can decline plasma levels of CRP, MCP-1 and frequency of cardiovascular events as well as increasing insulin sensitivity and improving glucose metabolism to unstable angina patients.

Objective To explore the level and the significance of amino-terminal propeptide of procollagen type Ⅲ(P Ⅲ NP)in the serum of hypertrophic scar patients at excessive stages.Methods The serum samples of 74 inpatients admmitted in Affiliated Fosham Hospital of Sun Yat-sen University from August 2007 to August 2009 suffering from long-persisting post-burn hypertrophic scar at various stages were collected.Serum samples of 12 were normal persons were also collected and used as control group.Hypertrophic scar group were divided into 4 subgroups according to the phase of scar and the serum concentrations of P Ⅲ NP were detected using the sensitive RIA method.Results The level of PⅢ NP increases gradually during the process of immature hypertrophic scar to mature scar before it peaking in 4 to 6 months scar subgroup.The concentration of PⅢ NP degreased gradually with the maturation of hypertrophic scar.Conclusions The high concentration of PⅢNP can reflect the high level of the synthesis of type Ⅲ collagen in the tissue of post-burn hypertrophic scar.The level of P Ⅲ NP is synonymous with the ongoing process of hypertrophic scar.PⅢ NP may be a satisfactory marker in discerning the growth and development of post-burn hypertrophic scar.

Objective To investigate the osteogenic ability of dextran sulfate/recombinant human bone morphogenetic protein-2/chitosan (DS/rhBMP2/CS) nano microspheres combined with coralline hydroxyapatite (CHA) in repair of segmental bone defects.Methods DS/rhBMP2/CS microspheres prepared by ionic crosslinking method were adsorbed into CHA by lyophilization.Seventy-two New Zealand rabbits were randomly divided into 3 equal groups after they had been made into models of bone defect at the right radius.The defects in the 3 groups were implanted respectively with CHA,rhBMP2/CHA and DS/rhBMP2/ CS/CHA.Another 18 animals served as a blank control group.Blood and bone samples were obtained at 4,8 and 12 weeks after implantation.The serum BGP was detected,and the bone grafts were scanned by micro-CT for calculation of volume ratio of the new bone.Hematoxylin and eosin (HE) staining was performed after bone decalcification.Results All the 72 animals recovered well without any infection or graft exposure.Gross observation at postoperative 12 weeks showed that the DS/rhBMP2/CS/CHA group was the best in the quality,quantity and strength of the new bone,as well as in the healing of bone defects.The serum levels of bone gamma-carboxyglutamic-acid-containing protein at all time points in the DS/rhBMP2/CS/CHA group were significantly higher than those in the CHA and rhBMP2/CHA groups (P ＜ 0.05).Micro-CT scanning demonstrated obvious progress in bone formation,cortical bone and marrow cavity at all time points in the DS/rhBMP2/CS/CHA group which showed significantly faster bone reconstruction synchronized with material degradation and significantly higher volume ratio of the new bone than the other 2 groups (P ＜ 0.05).Histological examinations showed better morphology of mature cortical bone and new marrow cavity at all time points in the DS/rhBMP2/CS/CHA group than in the other 2 groups.Conclusion Since DS/rhBMP2/CS/CHA possesses a better mechanism of sustained-releasing rhBMP2 to induce bone formation because of its reticular and hole-hole-connected structure,it may perform better in repairing segmental bone defects than simple CHA or rhBMP2/CHA.
