Objective To evaluate the elderly coronary in-stent restenosis risk factors and the incidence of restenosis. Methods Coronary angiography in 143 cases of patients with coronary heart disease were randomly selected, analyzing the characteristics of coronary heart disease, and 89 patients of them were reviewed coronary angiography, restenosis was observed, and the restenosis factors including age, sex, hypertension, diabetes, hyperlipidemia and coronary lesions, stent properties were analyzed. Results Statistical multi-vessel disease in patients with coronary heart disease was 73.9% ,restenosis rate was 23.5%. One narrow and contrast the age of the patients without stenosis and no statistically significant difference between lipids. The number of diabetes cases in the two comparison groups,stent length and stent volume were significant different. One bare stent restenosis rate was significantly higher than the drug-eluting stent group. Conclusion The results showed that diabetes ,stent length,multiple stents, stent restenosis,were the relevant factors of coronary restenosis.

To compare the economic efficacies of the oral antidiabetic drugs in National Essential Medicine for treating type 2 diabetes mellitus.200 diabetic patients with body mass indices between 19-27 kg/m2 were assigned into 5 groups:group A received glibenclamide,group B glipizide,group C metformin,group D glibenclamide +metformin,and group E glipizide + metformin.Pharmacoeconomic evaluation was performed by cost-effectiveness analysis( CEA ).Fasting glucose level in patients treated with these 5 drugs all decreased significantly,as well as HbA1c.Glibenclamide was more in line with the principles of pharmacoeconomics,but should be used carefully for its serious and prolonged hypoglycemia,especially in elderly patients.According to the method of cost-effectiveness analysis,it was more economical to use metformin to control fasting glucose level while it is more reasonable to use glipizide to control the postprandial glucose whereas controlling of postprandial blood glucose is considered as a priority.Glipizide+mefformin combination may be recommended to the patients whose blood glucose level is poorly controlled by a single drug alone.

The paper discusses the necessity and urgency of hospital ownership reform. and pinpoints the focal and difficult points of the task. It also identifies the goals of the reform, viz. establishment of a medical and health system that fits in with the development demands of a socialist market economy, which is of great significance. It can be seen both in theory and in practice that for a pretty long period of time in China, public hospitals, providing basic medical security for the broad masses of people will occupy a leading position whereas private hospitals known for their outstanding service and quality, will play a bigger role only when the living standards of the general population have reached a fairly high level.

Neovascularization plays an essential role in the process of renovation in tissue damage,tumor growth, and hormones action. Parathyroid hormone (PTH) is one of the basic hormones that regulate the serum calcium, phosphorus, and bone metabolism. In recent years, studies involving the neovascularization-mediated effects of PTH on metabolism are becoming more and more popular and wider. Based on recent researches, the purpose of this paper is to summarize the changes of angiogenesis while PTH interacts with its target organs, especially interacts with osseous tissue.

Objective To evaluate the clinical application value of flow fluorescence assay in determination of serum pepsinogenⅠ and Ⅱ.Methods The precision of flow fluorescence assay in the detection of serum pepsinogen Ⅰ and Ⅱ were evaluated. Methodology comparison were conducted between flow fluorescence assay and enzyme-linked immunosorbent assay(ELISA)kit through detecting clinical samples.The reference ranges for PGⅠ and PGⅡ/PGⅠ ratio of healthy population were established. The levels of PGⅠand PGⅡ/PGⅠ ratio were detected in serum samples of patients suffering superficial gastritis,atrophic gastritis and gastric cancer.Results The within-run and between-run coefficient of variation of PGⅠ were 4.26%-5.35% and 6.73%-7.75%,respectively.And those of PGⅡ were 5.48% - 6.42% and 8.46% -8.85%,respectively.Methodology comparison be-tween flow fluorescence assay and ELISA demonstrated good linear correlations.The linear equation wasY =0.91 1X -22.635(r=0.966,P <0.05)and Y =0.892X -0.548(r=0.980,P <0.05)for PGⅠ and PGⅡ,respectively.The lower limit of the reference range of PGⅠ and PGⅡ/PGⅠ ratio were 32.77 ng/mL and 4.1 6,respectively.The PGⅠ and PGⅠ /PGⅡ ratio of patients suf-fering atrophic gastritis and gastric cancer were statistically significantly lower than those in patients suffering superficial gastritis (P <0.05).Conclusion The flow fluorescence assay could conduct simultaneous detection of PGⅠ and PGⅡwith good methodo-logical performance and high efficiency.The determination of PGⅠ and PGⅡlevels through flow fluorescence assay could provide laboratory basis for the screening and diagnosis of atrophic gastritis and early gastric cancer.

Objective Diabetic mellitus is one of the major threats to human health.The prevalence of diabetes mellitus is growing rapidly worldwide.Patients with diabetes mellitus are at increased risk for cardiovascular diseases.Diabetic cardiomyopathy (DC) is related to diabetes-specific metabolism,but the mechanism is not entirely clear.Recent studies suggest that abnormal myocardial energy metabolism and reduced number of myocardial cells may be the important pathophysiological mechanism that leads to heart function impairment of diabetes patients.Mitochondria are not only an important place generating cellular energy,also involved in the apoptotic and death process of cells.Therefore,mitochondrial dysfunctions play a key role in the process of DC.Mitochondrial permeability transition (MPT) is a center for information exchange within and outside the mitochondria and plays a key role in the maintenance of mitochondrial function.MPT works through the mitochondrial permeability transition pore (MPTP).In our recent studies,it was found that MPTP function changed in DC and its abnormality could be corrected by specific AT I receptor antagonist.These findings are important for better understanding DC.
