Objective Glucagon-like peptide-1 (GLP-1) has been reported to be effective in the treatment of nonalcoholic fatty liver disease (NAFLD). However, the molecular mechanism of GLP-1 on NAFLD is remained unclear. The present study was to detect whether the effect of GLP-1 on triglyceride (TG) content in hepatocytes is dependent on Foxos. Methods HepG2 cells were treated with palmitic/oleic acid for 24 h. The knockdown of Foxo1, Foxo3 was conducted through small interfering RNA (siRNA). Real time PCT (RT-PCR) was used to detect the changes of the SREBP1c and Acox2 genes in HepG2 cells after Foxo1/3 knockdown. Results As expected, palmitic/oleic acid increased TG concentration in HepG2 cells [(12.65 ± 1.32) μg/mg vs. (4.32 ± 0.54) μg/mg, P<0.05]. Addition of GLP-1 dose (10, 50, 100nmol/L) dependently lowered the TG content and reached plateau at 100 nmol/L of GLP-1 [TG(8.38±1.47) μg/mg]. The GLP-1 effect on TG remained after knocking down either Foxo1 [(9.09±1.34)μg/mg] or Foxo3 [(8.90± 1.60) μg/mg] alone, but not when knocking down Foxo1 and Foxo3 (Foxo1/3) together [(14.66±1.77)μg/mg]. Moreover, knocking down Foxo1/3 also abolished GLP-1 effect on SREBP1c and Acox2 expression. Conclusion GLP-1 can inhibit the synthesis of TG in hepatocytes depending on Foxo1 and Foxo3. Further studies are needed to explore the specific mechanisms.

Objective The cancer risk of patients with diabetes mellitus who are treated by metformin declines remarkably in comparison to patients receiving other drug therapies.The article was to investigate the relationship between antineopastic activity and fatty acid synthase (FASN) of metformin in human hepatocellular carcinoma cell(HCC) line HepG2. Methods HepG2 cells were treated with various concentrations of metformin( 0, 1, 5, 10, 15 mmol/L) for 24, 48 and 72 h respectively and cell growth was assessed by CCK-8 assay.Positive control(paclitaxel 10μg/mL) and negative control(metformin 0mmol/L) were set up simultaneously.After being treated with doses of metformin(0, 5, 10,15mmol/L) for 72h, protein expression levels of AMPKα、P-AMPKα、FASN、P-mTOR and P-Akt were measured by western blotting analysis and FASN mRNA expression levels were measured by RT-PCR. Results Being treated with vari-ous doses of metformin(1, 5, 10, 15 mmol/L) for 24, 48 and 72 h, the growth of HepG2 cells were inhibited by metformin in dose-dependent and time-dependent manner( P0.05) .FASN mRNA expression levels decreased significantly in all metformin-treated groups( P<0.05) . Conclusion Met-formin actitiviates AMPK, inhibits mTOR and downregulates FASN, which are implicated in its antineopastic activity on HCC.Although metformin inhibits mTOR activation, it is not involved in Akt upregulation through a negative loop.

Adipocyte fatty acid-binding protein ( FABP4 ) is abundantly expressed in adipocytes and macrophages, and the physiologic function of this lipid chaperone is involved in the intracellular trafficking and targeting of fatty acids inside cell. Studies have shown that FABP4 plays a significant role in cholesterol metabolism. FABP4 can affect some key gene expression for cholesterol metabolism, thus regulate the metabolism, storage, and trafficking of cholesterol. As the development of FABP4 inhibitors, drugs targeting FABP4 are possible and can lead to a novel therapeutic strategy to prevent and treat obesity, type 2 diabetes, hypercholesterolemia, and atherosclerosis.

[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.

Patients with acute myocardial infarction(AMI) are often with elevated blood glucose level when admitted to hospital,this finding is associated with poor prognosis regardless of a history of diabetes.Though numerous studies have addressed some of the questions in this field,many critically important questions are still poorly understood and under debate.This article summarized current findings in hyperglycemia and its potential link withadverse outcomes in AMI patients,and addressed some of the existing controversies in this field.
RÉSUMÉ
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.

Objective Hyperglycemia was common during acute myocardiai infarction (AMI). This study investigated the impact of stress hyperglycemia on in-hospital outcomes in patients without diabetes hospitalized with AMI. Methods The study included 107 patients with AMI without diabetes, who were admitted to 81 hospital of PLA of Nanjing, China from January 2000 to May 2010. The in-hospital mortality and in-hospital complications were analyzed retrospectively. The exclusion criteria were: (1 ) patients < 18 years old; (2) patients with history of diabetes; (3) patients who initiated anti-hyperglycemic therapy during their hospital stay though without previously diagnosed diabetes; (4) patients with non-cardiovascular causes for AMI; (5) patients with hepatic failure, kidney failure, serious lung illnesses and end stage of malignant tumour; (6) patients administrated with steroid treatment recently and those with some diseases which had dramatic effect on glucose metabolism such as hyperthyroidism and cushing syndrome. Patients were categorized according to FBG levels into4 mutually exclusive groups; <7.0 mmol/L, ≥7.0 but <8.0 mmol/L, 8.0 to< 11. 1 mmol/L and ≥11.1 mmol/L. The Statistical Package for Stata, version 9.2 was used for statistical analysis. According to corresponding data analysis of /-test, ANOVA, rank test and exact propability were used respectively. Univariate logistics regression analysis was conducted followed by multivariate logistics regression analysis on significant variables. Results The incidence rate of stress hyperglycemia in patients with AMI without diabetes was 43. 9% (n =47). In non-diabetic patients, the mortality of the group of FBG≥7. 0 mmol/L was significantly higher than the group of FBG < 7. 0 mmol/L, which are 27.66% and 6.67%(P=0.0063)respectively,OR=5.35(95%CI 1.61 - 17.75,P = 0.0061). In-hospital complications for example lung infection, congestive heart failure, serious arrhythmias and acute cerebrovas-cular events were increased significantly in AMI patients with stress hyperglycemia. Multivariate logistic regression analysis for mortality were performed adjusting for risk factors which demonstrated FBG was a independent risk factors of in-hospital death , OR = 1.56(95%CIl.09 -2.23). Conclusions In-hospital mortality and in-hospital complications were significantly increased in patients with AMI without diabetes which developed stress hyperglycemia. Stress hyperglycemia was of great prognostic value for short-outcomes of AMI.

Objective To analyze the changes of the intima-media thickness(IMT)of carotid and femoral arteries, serum advanced glycosylation end-products(AGEs),and AGEs soluble receptor(sRAGE)after intensively controlling blood glucose, blood pressure, and lipid. Methods One hundred and thirty-two type 2 diabetic patients were divided into 3 groups and followed for 5 years: 20 patients were treated with intensive control of blood glucose and blood pressure, 80 patients with intensive control of blood glucose, blood pressure, and lipid; and 32 patients with conventional therapy. AGEs, sRAGE, and IMT of carotid and femoral arteries were measured and compared among different groups. Results The IMT of carotid and femoral arteries and serum level of AGEs were significantly decreased after intensive treatment. The ratio of sRAGE and HbA1C(sRAGE/HbA1C)were negatively correlated with the mean of HbA1Cin the past five years(r=-0.417, P＜0.001)and the fluctuation of HbA1C(r=-0.309,P＜0.001). Multinomial regression analysis showed that AGEs were the important risk factors of IMT of femoral artery(β=0.152,P=0.068). Conclusion Intensive treatment is significant in controlling the growing IMT of carotid and femoral arteries, while decreasing serum level of AGEs.

HepG2 ceils were treated with various concentrations of tumor necrosis factor-or (TNF-α) for 24 hours. RT-PCR and Western blot were used to measure protein tyrosine phosphatase-1 B(PTP-1B)expression, and luciferase reporter assay was used to detect NF-kB activity. The results showed that treatment of HepG2 cells with TNF-α for 24 hours led to upregulation of PTP-1B and NF-kB activity in a dose-dependent manner. Inhibition of NF-kB by PI)TC significantly attenuated TNF-α-induced PTP-IB expression in HepG2 cells. Thus, the transactivation of NF-kB seems to play an important role in the expression of PTP-1B in HepG2 cells induced by TNF-α.
