Objective To observe the therapeutic efficacy and safety of the glucagon-like peptide-1 ( GLP-1 )analogue combined with isulin for treating obese or overweight type 2 diabetes.Methods 40 cases with obese or overweight type 2 diabetic patients( body mass index(BMI) ≥24) who have previously used human insulin,and experienced poor glycemic control( ≥7.5％ ) were selected.They were randomly divided into two groups.A group treated by GLP-1 analogue liraglutide plus insulin,and B group by continuous adjustment of insulin.12 weeks later,fasting blood glucose(FBG),2-hour plasma glucose (2hPG),hemoglobin A 1 C (HbA1c),body weight were observed and the incidence of hypoglycemia,insulin dosage were recorded.Results Weight and insulin dosage of group A was significantly lower than those of group B after treatment 12 week( t =2.738,2.865,all P ＜ 0.01 ).Numbers of hypoglycemia events were 6 in group A(30％ ),and 9 in group B(45％ ),but there was no statistical significance between the two groups ( P ＞ 0.05).Conclusion The addition of liraglutide to insulin in patients with obese or overweight type 2 diabetes is associated with reductions in weight and insulin dosage,without increase risk of hypoglycemia.This treatment proved effective and safe.

Baicalein (BAI) is an effective bactericide. The antibacterial activity and mechanism experiments were carried out by determining conductivity and content of macromolecules of membrane penetrability, the oxidative respiratory metabolism and protein synthesis changes and the inhibition of DNA topoisomerase activities. Electrical conductivity and the number of large molecules of BAI increased 2.48% and 1.8%, respectively, than that of the control. However, the membrane integrity did not destroyed by BAI directly. With BAI treatment, inhibition rates of activities for SDH and MDH were 56.2% and 57.4%, respectively, demonstrating that BAI could inhibit cell respiratory. After treated with BAI for 20 h, the total soluble content of proteins decreased by 42.83%. Moreover, the activities of DNA topoisomerase I and II were inhibited completely by 0.2 mmol x L(-1) BAI. These results indicated that BAI had obvious antibacterial activity on Staphylococcus aureus. The mechanism is that it could affect bacterial membrane penetrability, inhibit protein synthesis and influence SDH, MDH and DNA topoisomerase I and II activities to exert its antibacterial functions.

Objective To analyze the relevant factors that influence the medicine-free re-mission rate after short-term continuous subcutaneous insulin infusion (CSII)in newly diagnosed patients with type 2 diabetes metillus (T2DM).Methods A total of 405 patients with T2DM hos-pitalized in our hospital from October 2003 to October 2012 served as the study objects,who were given CSII for 15 d and divided into success group (165 cases)and failure group (240 cases)based on the requirement of hypoglycemic agents after discharge from hospital.The relationship between ages,genders,body max index (BMI),fasting plasma glucose (FPG),glycated hemoglobin (HbA1c),ratio of 2 h C-peptide and fasting peptide (C2 /C0),attained time of plasma glucose and daily dosage of insulin during CSII with the clinical medicine-free remission rate after short-term CSII in patients with T2MD.Results Success group was evidently lower in FPG,HbA1c and daily dosage of insulin but obviously higher in C2 /C0 during CSII than failure group,and the differences were all statistically significant (P <0.01).Conclusion FPG,HbA1c and C2 /C0 can be used as the screening indexes for the diagnosis of T2DM patients treated with CSII,and T2DM patients with low FPG and HbA1c and high C2 /C0 are more suitable and should given CSII earlier so as to induce longer-term remission rate in clinic.
