Objective To assess the influence of different digestive tract reconstruction on the blood glucose of gastric antral cancer patients with type 2 diabetes. Methods The clinical data of 51 cases of gastric antral cancer with type 2 diabetes treated radical surgery in this hospital from January 2006 to January 2012 were analyzed retrospectively. The patients were divided into three groups according to the different digestive tract reconstruction methods：BillrothⅠ anastomosis group （n=14）， BillrothⅡ anastomosis group （n=28）， and Roux-en-Y anastomosis group （n=9）. The indexes were analyzed and compared among three groups：① The levels of fast blood glucose （FBG） and 2h postprandial blood glucose （PG2h） were detected before operation and on 1 month and 6 months after the operation；② The level of glycated hemoglobin （HbA1c） was detected before operation and 6 months after the operation；③ The diabetes control was observed. Results The FBG and PG2h levels in the BillrothⅠ anastomosis group detected on 1 month and 6 months after the operation were not statistically different from those detected before the operation （P＞0.05）. The FBG and PG2h levels in the BillrothⅡanastomosis group and Roux-en-Y anastomosis group detected on 1 month and 6 months after the operation were significantly lower than those before the operation respectively （P＜0.05）. The FBG and PG2h levels in the BillrothⅡ anastomosis group detected on 1 month and 6 months after the operation were not statistically different from those in the Roux-en-Y anastomosis group respectively （P＞0.05）， but which were markedly lower than those in the BillrothⅠ anastomosis group， the differences were statistically significant （P＜0.05）. The HbA1c levels in the BillrothⅠ anastomosis group detected before the operation and on 6 months after the operation were not statistically different from each other （P＞0.05）. The HbA1c levels in the BillrothⅡ anastomosis group and Roux-en-Y anastomosis group detected on 6 months after the operation were markedly lower than those before the operation and the difference was statistically significant （P＜0.05）. On 6 months after the operation， the HbA1c levels in the BillrothⅡanastomosis group and Roux-en-Y anastomosis group were markedly lower than those in the BillrothⅠ anastomosis group and the differences were statistically significant （P＜0.05）；the HbA1c level was not statistically different between the BillrothⅡ anastomosis group and the Roux-en-Y anastomosis group （P＞0.05）. The total curative effects in the BillrothⅡ anastomosis and Roux-en-Y anastomosis groups were significantly better than those in the BillrothⅠ anastomosis group （P＜0.05）. Conclusion According to our limited clinical data， BillrothⅡ anastomosis and Roux-en-Y anastomosis for gastric antral cancer patients with type 2 diabetes may be the best surgical approach.

Methods A total of 120 patients with type 2 diabetes treated between March 2001 and July 2009 were randomly divided into the intervention group and the control group with 60 patients in each. Medicine treatment was carried out for patients in both groups, and psychological intervention was applied only to the intervention group. Eight weeks later, self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were used to evaluate emotion changes of the patients. Fasting blood glucose, post-meal blood glucose (P2hBG) examination were conducted at the same time. Results The result showed a significantly larger decrease of both fasting blood glucose and post-meal blood glucose in the intervention group than the control group (Plt;0.05). Through these methods, the SAS and SDS evaluation of patients in the intervention group improved significantly (Plt;0.05); However, the change of these two scores was not statistically significant in the control group (Pgt;0.05). There was a mid-level correlation between the blood sugar level of diabetic patients and SAS, SDS evaluation scores (0.4lt;|r|lt;0.6, Plt;0.05). Conclusion The blood sugar level of patients with diabetes is closely related to SAS and SDS scores, and psychological intervention can significantly improve the control of blood glucose and emotions of the patients.
Objective To observe the curative effect on non-obese type 2 diabetes and the effect on change of glucagon-like peptide-1 (GLP-1) of gastric bypass operation. Methods Thirty-two cases of gastric ulcer with non-obese type 2 diabetes were suffered gastric bypass operation. Plasma glucose concentrations, insulin and GLP-1 were measured respectively in fasting and postprandial conditions before operation and in week 1, 2, 3 and month 1, 3, 6 after gastric bypass operation, and the body mass index (BMI), homeostasis model assessment β cell function index (HBCI) and glycosylated hemoglobin (HbA1c， the index was detected only before operation and in month 3, 6 after operation) were also measured. The turnover of the diabetes condition in the 6th month after surgery was observed. Results Compared with the levels before operation, the fasting and postprandial plasma glucose levels were descending (P＜0.05), fasting and postprandial plasma insulin and GLP-1 levels were ascending (P＜0.05), HBCI was ascending and HbA1c was descending significantly after operation respectively (P＜0.05), while BMI changed un-significantly after operation (Pgt;0.05). The diabetes control rate was 78.1%(25/32) overall six months after operation. Level of GLP-1 was negatively correlated with level of plasma glucose (P＜0.05) and positively correlated with level of insulin (P＜0.05). Conclusions Gastric bypass operation can markedly reduce plasma glucose level on the type 2 diabetes patients with non-obese, and the hypoglycemic effect may be contributed by more GLP-1 secretion that caused more insulin secretion, which doesn’t depend on the loss of weight.
Objective To explore the feasibility and operation points of establishing duodenal-jejunal bypass （DJB）surgery animal model in Goto-Kakizaki （GK） rats. Methods Sixteen GK rats were randomly divided into experimental group （n=8） and control group （n=8）. In a standardized preoperative， intraoperative， and postoperative operation， the rats of experimental group and control group received DJB and sham surgery respectively. The fasting plasma glucose and body mass were observed before operation， and 1， 2， 3， and 4 weeks after operation in order to evaluate whether the models were established successfully. Survival situation of rats were observed too. Results All experimental rats survived at 4 weeks after the operation. Compared with the levels before operation， the fasting plasma glucose levels of experimental group decreased significantly （P＜0.05） at 1 week after operation， and remained stable at 2， 3， and 4 weeks after operation.The fasting plasma glucose levels of control group did not change statistically at all time points after operation （P＞0.05）. Compared with control group at the same time point， the fasting plasma glucose level of experimental group was lower （P＜0.05）， indicating that DJB models were established successfully. After 4 weeks， the value of body mass added in experimental group was significantly lower than those of control group （P＜0.05）. Conclusions DJB is a feasible， safe， and effective hypoglycemic surgery. The application of this set of experimental operating procedures can reduce the risk of intraoperative and postoperative mortality， and can develop a stable DJB model in Goto-Kakizaki rats.
ObjectiveTo explore the effect of transplanting neonatal porcine islet cells of pig via hepatic portal vein in type Ⅰ diabetic monkeys.MethodIn this study, three pig-monkey islet xenotransplantation experiments were carried out by using α-1, 3-galactosyltransferase (GGTA1) gene knockout neonatal pig islet cells.ResultsThree macaques were successfully transplanted with islet cells. After the operation, their vital signs were stable and no symptoms of venous embolism occurred. After transplantation, the blood glucose and the dosage of exogenous insulin were significantly reduced, and the specific porcine C-peptide could be detected. Three macaques developed symptoms of ketoacidosis, and one macaque developed wound infection. After symptomatic treatment, all of them survived for 16 weeks.ConclusionGGTA1 knockout neonatal porcine islet cells transplanted through hepatic portal vein is effective for the treatment of type Ⅰ diabetes.
Objective To summarize the relationship of diabetes and its complications with microRNA. Methods Domestic and international researches were collected by searching to summarize the role of microRNA in diabetes and its complications. Results MicroRNA could affect the secretion of insulin and interfer metabolism of gulcose in fat cells， muscle cells， and liver cells， which resulting in insulin resistance. At the same time， the microRNA also played an role in damage of vascular endothelial cells and myocardial cell in diabetes. Conclusion MicroRNA acts an important role in the process of diabetes and its complications.
ObjectiveTo investigate the association between single nucleotide polymorphism (SNP) rs3754219 in the glucose transporters 1 (GLUT1) gene and genetic susceptibility to type 2 diabetes mellitus (T2DM) in Han population in Guangdong Province.MethodsA total of 1 092 T2DM patients (case group) and 1 092 healthy controls (control group) diagnosed or examined between November 2011 and October 2014 form 10 hospitals were enrolled in this study. SNPscanTM SNP classification technology was used to detect the polymorphism of rs3754219 of GLUT1 genetype. Finally, 1 067 T2DM patients and 1 054 healthy controls were included, removing 37 individuals with SNP typing deletion rates >20% and 26 individucals with failed SNP site genotyping. The differences in allele frequency distribution, genotype, and genetic models between the two groups were analyzed.ResultsAfter correction for age and body mass index, there was no statistically significant difference in allele frequency or polymorphism genotype frequency of rs3754219 (P>0.05). There was no statistically significant difference between the two groups under different genetic models (P>0.05).ConclusionGenetic susceptibility to T2DM in Han population in Guangdong Province may be unrelated to the GLUT1 rs3754219 SNP.
Objective To study the therapeutic effect of Roux-en-Y gastric bypass （RYGB） on type 2 diabetes mellitus （T2DM） rats and explore the possible mechanism of vaspin in RYGB on T2DM. Methods Twenty SD rats with T2DM and 20 age- and sex-matched normal SD rats were randomly divided into 4 groups according to the random digits table：T2DM-RYGB group， T2DM-sham operation （SO） group，RYGB group，and SO group，10 rats in each group. Fasting plasma glucose （FPG） level，serum insulin （INS） level，vaspin level，and homeostasis model of insulin resistance （HOMA-IR） were determined before operation and on week 4，8 after operation，respectively．At the same time，the correlation between vaspin and the indicators （FPG，INS，or HOMA-IR） was analyzed．Results Compared the indicators after operation with before operation，the FPG level，INS level，vaspin level，and HOMA-IR were not significantly different between the T2DM-RYGB group and T2DM-SO group （P＞0.05） or between the RYGB group and SO group （P＞0.05），but the FPG level，INS level，vaspin level，and HOMA-IR in the T2DM-RYGB group and T2DM-SO group were significantly higher than those in the RYGB group （P＜0.05） and SO group （P＜0.05），respectively. On week 4 after operation，the FPG level，INS level，vaspin level，and HOMA-IR decreased in the T2DM-RYGB group，except for the FPG level，the other indexes had no significant differences as compared with the values before operation. On week 8 after operation，the FPG level，INS level，vaspin level，and HOMA-IR further decreased in the T2DM-RYGB group，there were significant differences of these indicators between before operation and on week 8 after operation. Compared the indicators after operation with before operation，the FPG level，INS level，vaspin level，and HOMA-IR were not statistically significant （P＞0.05） in the T2DM-SO group，RYGB group，or SO group. The changes in serum vaspin level correlated positively with those in INS and HOMA-IR before operaion and on week 4，8 after operaion in the T2DM-RYGB group and T2DM SO group rats （P＜0.05），respectively. Conclusions RYGB surgery has a therapeutic effect on T2DM rats，and serum vaspin level decreases and insulin resistance is improved after RYGB surgery，which may be one of the mechanisms of the treatment for T2DM.
