Type 2 Diabetes is the consequence of the disturbances of both α- and β-cell secretions.Glucagon-like peptide-1 ( GLP-1 ),which regulates the function of alpha and beta cells,has led to the emergence of a new class of oral anti-diabetic drugs.DPP-4 inhibitors,which increase the concentration of GLP-1 and consequently improve HbAlC,have become a choice for patients in different stages of diabetes.

Objective To investigate the feasibility of segmental splenectomy for treatment of splenic benign tumor. Methods The clinical data of 6 patients with splenic benign tumor treated in our hospital with spleen-preserving surgery in the past 2 years were retrospectively analyzed. Results All the 6 patients successfully underwent surgery and recovered smoothly after operation. No acute severe infection occurred. Ultrasonography showed that the blood supply of residual spleen was of no problem. The components of peripheral blood had no significant changes after operation. Conclusion As long as we know the vascular anatomy of spleen well, segmental splenectomy is safe, reliable and feasible.

Objective To observe the effect of liraglutide on arteriosclerotic lesions in diabetic ApoE- / - mice via regulating receptor for advanced glycation end-products ( RAGE) expression of aorta. Methods Thirty male ApoE- / - mice (10 weeks) were randomly divided into 3 groups: control group, diabetes group, and diabetes +liraglutide group. All the mice were fed a high-fat diet. Diabetes was induced by 2 intraperitoneal injection of streptozotocin (STZ, 55 mg·kg-1 ·d-1 ). Mice were treated with subcutaneous injection of liraglutide (0. 4 mg· kg-1 ·d-1 ) in diabetes+liraglutide group. After 9 weeks, blood was drawn and the aorta were rapidly procured. The serum levels of advanced glycation end-products ( AGEs), soluble receptor for advanced glycation end-products (sRAGE ), stromal cell-derived factor-1α ( SDF-1α ), as well as total cholesterol and triacylglycerol were measured. Atherosclerotic plaque area was determined by Sudan Ⅳ staining. The expression of RAGE was determined using RT-PCR and western blot, respectively. Results Compared with control group, the serum AGEs, the RAGE protein and mRNA expression, the atherosclerotic lesions were significantly increased in the mice of diabetes group. Compared with diabetes group, the serum AGEs, the RAGE protein and mRNA expression, the atherosclerotic lesions were significantly decreased in the mice of diabetes+liraglutide group. Conclusion Liraglutide is confirmed as to have an anti-atherosclerotic effects and inhibits RAGE expression in diabetic ApoE- / - mice.

Objective　To examine the intraindividual reproducibility of the octanoic acid breath test in normal subjects and diabetics and to investigate whether cardiovascular autonomic neuropathy and delayed gastric emptying influence the intraindividual reproducibility.Methods　Nine normal subjects (six men, three women,mean age 38 years) and 15 diabetics with insulin treatment ［nine men, six women; mean age 47 years; six had cardiovascular autonomic diabetic neuropathy (CADN) and/or delayed gastric emptying time］ were, after a nocturnal fasting period, given a standard test meal (labeled with 13C-octanoic acid, 1 046 kJ). Breath samples were taken at ten minute intervals over first one hour and at fifteen minute intervals over the following three hours and examined for 13CO2 by isotope ratio infrared spectrometry. Using a regression method gastric emptying half times (t1/2) and lag phase (tlag) were determined.Results　There was not a significant difference of t1/2 and tlag between two measurements in normal subjects and diabetics. The coefficients of variation of day-to-day reproducibility were 11.7% for t1/2, 19.4% for tlag in normal subjects and 17.8% for t1/2, 28.2% for tlag in diabetics, but there was not significant difference between normal subjects and diabetics. There was not significant difference of intraindividual coefficient of variation of t1/2 and tlag between diabetics with/without CADN and between diabetics with normal gastric emptying time and diabetics with delayed gastric emptying time.Conclusions　 The 13C-octanoic acid breath test has a high intraindividual reproducibility which is not affected by the cardiovascular autonomic neuropathy and delayed gastric emptying. It can be recommended as a non-invasive test for assessing gastric emptying time after a solid test meal in diabetics.
