Metabolic surgery have the ideal weight loss effect,can maintain the long-term ideal weight,and its effects on blood glucose control is better than the simple medical treatment.Therefore,metabolic surgery received widespread attention in China.More and more patients undergo metabolic surgery,but the surgeons often pay attention to the operation,neglecting the use of drugs after surgery.The patients are always complicated with a lack of vitamin and metabolic syndrome,such as type 2 diabetes mellitus,hypertension,polycystic ovary,sleep apnea,cardiovascular disease.Patients have taken drugs before surgery can cause esophageal reflux,ulcer,anemia,loss of calcium and other complications,patients need to be supplied with vitamins and minerals after surgery.So more attention should be paid to the rational application of drugs after surgery,to prevent adverse reactions from improper use of drugs,and reduce the incidence of postoperative complications.

OBJECTIVE: To discuss the biosafety and biocompatibility of biomaterials. METHODS: A computer-based online search of CNKI, CBM and VIP as well as manual search were performed to collect articles about random cell control experiments and animal experiments of biological material biocompatibility published between 1990 and 2008. A total of 28 Chinese literatures were collected, and 7 were included mainly involving the cytotoxicity test methods and blood compatibility of the experimental medium, experimental grouping, experimental materials, methods of observation, experimental results, and experimental conclusion. In addition, biocompatibility of the biological material was analyzed to summarize the biocompatibility of the biological safety. RESULTS: Based on experiments of biosafety and biocompatibility of biomaterials, the cytotoxicity test and blood compatibility of various biomaterials, such as collagen, chitosan, magnetic nanoparticle, metal vascular stent, sulphurated siliastic medical grade silicon rubber, polyurethane, ceramic coatings by micro-arc oxidation, are essential for the biological safety. The experimental results have shown that the biomaterials have good biocompatibility. CONCLUSION: A variety of biological materials present good biocompatibility, including collagen, chitosan, magnetic nanoparticle, metal vascular stent, sulphurated siliastic medical grade silicon rubber, polyurethane, ceramic coatings by micro-arc oxidation, based on the evaluation criteria.

Granulocyte colony-stimulating factor is a glycosylated polypeptide chain cell growth factor that can promote proliferation and differentiation of myeloid progenitors and induce maturation of these cells toward terminally differentiated neutrophils.Granulocyte colony-stimulating factor which functions and effects depend on the combination with specific receptor on the surface of effector cells.With the development of gene cloning technology,ganulocyte colony-stimulating factor recombinant products have been widely used in clinic to provide effective means for the treatment of leucopenia,In recent years,we find the therapy of chemotherapeutics combining with granulocyte colony-stimulating factor is effective in refractory/relapsed/elderly cases of acute leukaemia.Currently,granulocyte colony-stimulating factor is one of important and successful hematopoietic cytokines in clinic.

90%, respectively. Although some shape changed red blood cells were observed in the washed blood, discocytes were the dominant form, with the percentage of discocytes being (58.0 ? 8.0)%. A greater number of shape-changed red blood cells were found in 2-week-old banked RBCs (P

Leptin,a peptide hormone synthesized and secreted primarily by adipose tissue,plays an important role in the regulation of body weight,metabolic and endocrine responses.It has emerged recently as a protective factor in multiple organ resistance to injury.We reviewed the protective effect of leptin and its possible mechanism.

Coronary heart disease (CHD) is a major disease greatly harmful to the health of human beings. The incidence and case fatality rate of female CHD show an increasing tendency due to lack of enough attention. Through analyzing the epidemiology, risk factors, and clinical characteristics of female CHD, we emphasized that it is necessary to pay enough attention to the particularity of female CHD, and put forward the thinking way of diagnosis and treatment of integrative medicine as "integrating Chinese medicine and Western medicine by mutual complement of advantages; combining syndrome typing and disease identification by grasping laws; treating physically and mentally by a wholism concept; spreading health education, preventing and treating comprehensively".

Objective · To observe the changes in peripheral blood CD14dimCD16+ monocyte count and serum C-reactive protein (CRP) level in elderly patients with chronic heart failure (CHF) and analyze the relationship between these changes and the cardiac function of patients. Methods · 42 elderly patients with CHF (the CHF group, consisting of 18 cases of NYHA cardiac function grade Ⅱ , 18 cases of NYHA cardiac function grade Ⅲ , and 6 cases of NYHA cardiac function grade Ⅳ) and 25 healthy elderly people (the control group) were enrolled. Peripheral blood CD14dimCD16+ monocyte count, serum CRP level, left ventricular ejection fraction (LVEF), and left ventricular end-diastolic diameter (LVEDD) were measured and statistical analysis was performed. Results · CD14dimCD16+ monocyte count and serum CRP level were significantly higher in the CHF group than in the control group (P<0.05). In the CHF group, the CD14dimCD16+ monocyte count, serum CRP level, and LVEDD of NYHA grade Ⅳ patients were significantly higher than those of NYHA grade Ⅱ patients, while their LVEF was remarkably lower than that of NYHA grade Ⅱ patients. The differences were statistically significant (P<0.05). Correlation analysis results showed that peripheral blood CD14dim CD16+ monocyte count and serum CRP level were positively correlated with LVEDD (r =0.37, r =0.45, P<0.05) and negatively correlated with LVEF (r =-0.56, r =-0.33, P<0.05) in the CHF group. Conclusion · The deterioration of elderly patients with CHF is associated with inflammation and the monocyte dysfunction may exist in the heart failure process. Peripheral blood CD14dim CD16+ monocyte count and serum CRP level are expected to be novel biomarkers that can reflect the severity of heart failure.

Type 2 diabetes(T2DM) is the collective result of insulin resistance in both muscle and liver andβ cell function failure. Traditional pharmaceutical therapy fails in ceasing progressive decline in β cell function. Bariatric surgery has been widely accepted as an efficient measure to treat diabetes. However, the prevalent standards mainly based on body mass index can not meet the demand for promoting remission rate. Related factors should be included in prediction of post-operative remission, like end-point setting, T2DM status, biochemical index, and operative method etc. The combination of these factors can be used to benefit more patients with diabetes.

Phase-contrast magnetic resonance imaging (PC-MRI) is a valuable and noninvasive method for evaluating hemodynamics and assessing the severity of disease processes involving the cardiovascular system. The basical principles, influential factors and the applications of PC-MRI in the assessment of cardiovascular diseases were reviewed in this paper.
