China is the country with the biggest diabetic population in the world.Diabetes has become a heavy financial burden for diabetic patients,families,and society.This article briefly described pharmacoeconomic concepts and analysis methods,and systemically reviewed literatures in health economic data of DPP-4 inhibitors,in the hope of providing a new perspective for clinicians,researchers,and health care policy makers.

Obesity is associated with numerous metabolic abnormalities, including insulin resistance and type 2 diabetes. Losing weight is an effective way of improving insulin sensitivity, thus decreasing the risk of obesityassociated diabetes and chronic cardiovascular disease. There is evidence that Liraglutide, as a human glucagon-like peptide-1 ( GLP-1 ) analogue, either using alone or combining with other glucose-lowering drugs, has effect on improving glycemic control, protecting β-cell function, and reducing body weight via inhibiting feeding behavior and delaying gastrointestinal motility. Therefore, liraglutide is a new option for treating type 2 diabetes patients.

Weight management is an important step in the treatment and management for type 2 diabetes.Obesity,especially visceral fat accumulation,impairs the metabolism function.Excess of visceral fat is closely related to the development of insulin resistance,metabolic syndrome,type 2 diabetes,and cardiovascular disease.Liraglutide,the (GLP-1) analogue,shows its effects on glycaemic control as well as weight reduction which mainly involves reduction of visceral fat.The efficacy characteristics of liraglutide may benefit the comprehensive management of type 2 diabetes.

The rat model of obesity was induced by high fat diet and in situ hybridization was performed with oligonucleotide probes.The results showed that expressions of leptin receptor mRNA and neuropeptide Y mRNA were significantly increased, suggesting that these increments might be related to leptin resistance.

Objective To observe the effects of high-fat diet on insulin sensitivity in rats. Methods Normal rats were fed with equicalorical high-fat diet and then treated with troglitazone. Glucose-insulin tolerance test was used to measure insulin sensitivity, blood pressure, blood glucose, insulin, endothelin, lipid, tissue glycogen and triglyceride levels. Results high-fat diet had no effect on body weight gain and blood pressure. Fasting and postprandial blood glucose levels were similar among the different groups. The levels of blood insulin, triglyceride, cholesterol and endothelin increased markedly, and the decrease in tissue glycogen level was also found. high-fat feeding caused insulin resistance after 4 weeks (K 5.63 vs. control 7.77, P

Objective To investigate the association of Lys656Asn polymorphism in leptin receptor gene with serum triglyceride level.Methods The genotypes of Lys656Asn polymorphism in LepR gene were maped by polymerase chain reaction-single strand conformation polymorphism(PCR-SSCP) assay in 232 unrelated subjects of Shanghai Chinese population.The clinical data were also analyzed.Results No significant difference of genotype frequency of Lys656Asn polymorphism in LepR gene was observed between obese and non-obese groups.In obese group,"G" Allele was associated with increased triglyceride level(1.74?0.91 vs 0.95?0.32)(P

Objective: To investigate the expression level of FOXC2 in adipose tissues and its correlation with obesity and insulin resistance Methods: Abdominal visceral and subcutaneous adipose tissue biopsies were obtained from 15 non-diabetic obesity patients(BMI≥35) and 8 non-diabetic controls(BMI

Objective:To investigate the correlation of serum blood pressure, serum lipid, fasting glucose, 2-h postprandial glucose, fasting insulin and uric acid with abdominal obesity in adolescents. Methods: Altogether 174 high-school students (101 male, 73 female, age range: 17-21 years) were selected from Yangpu District of Shanghai and studied in the body mass index (BMI), waist circumference, blood pressure, serum lipid, fasting glucose, 2h postprandial glucose, fasting insulin and uric acid. Based on BMI and waist circumference, the subjects were divided into Group A (normal weight), B (non-abdominal obesity) and C (abdominal obesity). Results: Compared with Group A, increased SBP, DBP, TG, HDL-C, LDL-C, FINS, HOMA-IR and Ua were observed in Groups B and C, and significantly increased FPG and 2 h PG were noted in Group C (P

The new protein suppressors of cytokine signaling(SOCS) as negative regulators of signaling pathways involve in the cellular actions of many cytokines, including leptin. It regulates intracellular signal transduction cascades such as the JAK STAT pathway. SOCS is now evident of leptin resistance and has close relation with obesity. We reviewed the structure and function of SOCS 3 and the mechanism in leptin signaling pathway,providing data for the potential effect of SOCS 3 in the treatment of obesity.

[Summary] The incidence of obesity and obesity‐related diseases (such as T2DM) increases year by year in the world. Metabolic surgery has increasingly been applied to patients with severe obesity. Studies have indicated that metabolic surgery is effective in obesity and obesity‐related diseases. Since patients undergoing metabolic surgery are obese or severely obese ,whose physiological and pathological changes are different with those of non‐obese patients ,a comprehensive assessment and management during perioperative period and after the operation were needed. This article mainly expounds preoperative evaluation and preparation ,management of surgery process and postoperative nutrition and endocrine management.
