Objectives To assess the effects of alpha-glucosidase inhibitors in patients with type 2 diabetes mellitus. Method We searched The Cochrane Library, MEDLINE, EMBASE, Current Contents, LILACS, databases of ongoing trials, reference lists of reviews on the topic of alpha-glucosidase inhibitors and we contacted experts and manufacturers for additional trials. Date of most recent search: December 2003 (Current Contents) and April 2003 (other databases). Randomised controlled trials of at least 12 weeks duration comparing alpha-glucosidase inhibitor monotherapy in patients with type 2 diabetes with any other intervention and that included at least one of the following outcomes: mortality, morbidity, quality of life, glycemic control, lipids, insulin levels, body weight, adverse events. Two reviewers read all abstracts, assessed quality and extracted data independently. Discrepancies were resolved by consensus or by the judgement of a third reviewer. A statistician checked all extracted data entrance in the database. We attempted to contact all authors for data clarification. Results We included 41 trials (8130 participants), 30 investigated acarbose, seven miglitol, one trial voglibose and three trials compared different alpha-glucosidase inhibitors. Study duration was 24 weeks in most cases and only two studies lasted amply longer than one year. We found only few data on mortality, morbidity and quality of life. Acarbose had a clear effect on glycemic control compared to placebo: glycated haemoglobin –0.77% (95% confidence interval –0.90 to –0.64), fasting blood glucose –1.1 mmol/L (95% confidence interval –1.4 to –0.9), post-load blood glucose –2.32 mmol/L (95% confidence interval –2.73 to –1.92). The effect on glycated haemoglobin by acarbose was not dose-dependent. We found a decreasing effect on post-load insulin and no clinically relevant effects on lipids or body weight. Adverse effects were mostly of gastro-intestinal origin and dose dependent. Compared to sulphonylurea, acarbose decreased fasting and post-load insulin levels by –24.8 pmol/L (95% confidence interval –43.3 to –6.3) and –133.2 pmol/L (95% confidence interval –184.5 to –81.8) respectively and acarbose caused more adverse effects. Conclusions It remains unclear whether alpha-glucosidase inhibitors influence mortality or morbidity in patients with type 2 diabetes. Conversely, they have a significant effect on glycemic control and insulin levels, but no statistically significant effect on lipids and body weight. These effects are less sure when alpha-glucosidase inhibitors are used for a longer duration. Acarbose dosages higher than 50 mg TID offer no additional effect on glycated haemoglobin but more adverse effects instead. Compared to sulphonylurea, alpha-glucosidase inhibitors lower fasting and post-load insulin levels and have an inferior profile regarding glycemic control and adverse effects.
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 observe the influence and interaction of duodenal jejunal bypass (DJB) and hepatic branch of vagus on glucose metabolism, and fasting serum glucagon like peptide-1 (GLP-1), peptide YY (PYY) in non-obese rat with type 2 diabetes mellitus (T2DM). MethodsForty non-obese Wistar rats (GK) with T2DM were randomly divided into four groups: sham operation group (SO group), sham operation plus hepatic branch of vagus resection (HBVR) group (SO+HBVR group), DJB group, and DJB+ HBVR group. The changes of preoperative and postoperative body weight, fasting blood glucose level, fasting serum insulin level, fasting serum GLP-1 and PYY contents among four groups were observed. ResultsIn the DJB group, the postoperative body weight and fasting blood glucose level were decreased significantly (P < 0.05) and the fasting insulin level, fasting serum GLP-1 and PYY contents were increased significantly (P < 0.05) as compared with the preoperative corresponding values in the same group, and it was found that the hepatic branch of vagus could more lastingly maintain postoperative lower body weight (P < 0.05), improve the level of insulin (P < 0.05), increase the fasting serum GLP-1 and PYY contents (P < 0.05) as compared with the DJB+HBVR group. ConclusionDJB could improve glucose metabolism effect of GK rats, the hepatic branch of vagus might play a role in it, too.
A lot of evidence-based medical evidence has shown that laparoscopic Roux-en-Y gastric bypass (LRYGB) is a durable and effective method for obesity and diabetes, and can significantly improve a series of obesity-related metabolic complications. This guideline provides a detailed description of the main operating steps and technical points of the symmetric three-port LRYGB, including posture layout, trocar position selection, liver suspension, gauze exposure, production of small gastric sacs, gastrojejunal anastomosis and production of biliary pancreatic branches, entero-enteric side to side anastomosis, closure of gastrointestinal anastomosis and mesenteric hiatus, greater omentum coverage, and closure of incisions. The purpose is to standardize the operating process of the symmetrical three hole method of LRYGB, providing standardized surgical operation references for clinical doctors in the field of obesity metabolic surgery.
Objective To explore the effect and mechanism of sleeve gastrectomy （SG） for type 2 diabetes mellitus （T2DM） in Goto-Kakizaki （GK） rats. Methods Thirteen male GK rats at 12 weeks of age were randomly divided into SG group （n=7） and sham operation group （SO group， n=6）， receiving SG surgery and sham operation respectively.Body weight， food intake in 24hours， fasting plasma glucose， plasma glucagon-like peptide-1 （GLP-1）， and plasma Ghrelin of rats in 2 groups were measured or tested before operation， 1， 4， 10， and 26 weeks after operation. In 10 weeks after operation， fecal energy content of rats in 2 groups was tested， in addition， oral glucose tolerance test （OGTT） and insulin tolerance test （ITT） were performed to investigate the glucose tolerance and insulin sensitivity. Results ①Body weight：there were no significant difference on body weight between the 2 groups （P＞0.05）. Compared with time point of before operation， the body weight of both 2 groups decreased in 1 week after operation （P＜0.01）， but increased in 10 weeks and 26 weeks （P＜0.01）. ②Food intake in 24 hours：compared with SO group， the food intake of SG group were lower in 4 weeks and 10 weeks after operation （P＜0.05）. Compared with time point of before operation， the food intake of SG group were lower in 1， 4， and 10 weeks after operation （P＜0.05）， but lower only in 1 week in SO group （P＜0.05）. ③Value of fasting glucose：compared with SO group， the value of fasting glucose in SG group were lower after operation （P＜0.01）. Compared with time point of before operation， the value of fasting glucose of SG group were lower after operation （P＜0.01）， but decreased in 1 week only in SO group （P＜0.01）. ④Level of serum GLP-1：compared with SO group， the levels of serum GLP-1 in SG group were higher in 4， 10， and 26 weeks after operation （P＜0.05）. Compared with time point of before operation， the levels of serum GLP-1 in SG group were higher in 4， 10， and 26 weeks after operation （P＜0.05）， but levels of serum GLP-1 in SO group didn’t change significantly （P＞0.05）. ⑤Level of serum Ghrelin：compared with SO group， the levels of serum Ghrelin in SG group were lower at alltime points after operation （P＜0.01）. Compared with time point of before operation， the levels of serum Ghrelin in SGgroup were lower at all time points after operation （P＜0.001）， but levels of serum Ghrelin in SO group didn’t change significantly （P＞0.05）. ⑥Areas under curves （AUC）：the AUC of OGTT and ITT test in SG group were both lower than those of SO group （P＜0.01）. Conclusion SG surgery can induce the level of fasting plasma glucose， and canimprove glucose tolerance and insulin sensitivity with significant changes of levels of plasma GLP-1 and Ghrelin， sugg-esting that SG surgery may be a potential strategy to treat patient with T2DM but without obesity or insulin resistance.
Exercise is vital for diabetics to improve their blood glucose level. However, the quantitative relationship between exercise modes (including types, intensity, time, etc.) and the blood glucose is still not clear. In order to answer these questions, this paper established a blood glucose metabolic model based on ordinary differential equation method. Furthermore, a silico method was adopted to study the effects of different aerobic exercise intensities (light, moderate and vigorous) on blood glucose and optimal strategies of insulin infusion for type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM). Additionally, the universality of proposed model and insulin infusion strategies was verified based on 1 000 virtual diabetes patients’ simulation. The experimental results showed that: (1) Vigorous-intensity aerobic exercise may result in hypoglycemia (< 3.89 mmol/L), which was so harmful to health that diabetics should avoid. Compared with moderate-intensity exercise, the light-intensity aerobic exercise intuitively lowered blood glucose slowly and caused a relative long high-blood-glucose (> 6.11 mmol/L) period, however, its overall blood glucose risk index (BGRI) was lower. (2) Insulin dosage of the optimized strategies decreased by 50% and 84% for T1DM and T2DM when they did moderate intensity exercise. As for light intensity exercise, the dosage of insulin was almost the same as they didn’t do exercise, but BGRI decreased significantly. (3) The simulations of 1 000 virtual diabetic patients manifested that the proposed model and the insulin infusion strategies had good universality. The results of this study can not only help to improve the quantitative understanding about the effects of aerobic exercise on blood glucose of diabetic patients, but also contribute to the regulation and management of blood glucose in exercise mode.
Objective To investigate the association of the polymorphism of resistin gene SNP-420C/G and type 2 diabetes (T2DM) among the Chinese Han population. Methods Such databases as CNKI, WanFang database, VIP, SinoMed, and PubMed were electronically searched from January 2001 to July 2010 to collect case-control studies on polymorphism of resistin gene SNP-420C/G and T2DM among the Chinese Han population. The quality of the included studies was evaluated and the data was extracted. RevMan 4.2 software was used for meta-analyses. Results A total of five case-control studies were identified, involving 709 cases in the T2DM group and 572 cases in the control group. The results of meta-analysis showed that the Chinese Han population with CC genotypes of SNP-420 had no higher risks to T2DM (OR=1.02, 95%CI 0.81 to 1.29), and the Chinese Han population with GG genotypes of SNP-420 still had no higher risks to T2DM (OR=1.34, 95%CI 0.95 to 1.90). Conclusion Current evidence suggests that there is no association between the polymorphism of resistin gene SNP-420C/G and risk to T2DM among the Chinese Han population.
ObjectiveTo explore the association between paroxetine (Seroxat) and level of blood sugar and endocrine hormones in pre-diabetes patients with anxiety and depression. MethodsFifty-four pre-diabetes patients with anxiety and depression diagnosed from January 2010 to December 2012 were recruited. The self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were used to assess depression and anxiety. All the patients were treated by paroxetine. The glucose tolerance test (OGTT), ACTH and cortisol were tested in patients at baseline and within 24 weeks. ResultsAfter 24 weeks' treatment, the level of anxiety and depression as well as the OGTT 0.5 h (0.5 h PG), OGTT 1 h (1 h PG), OGTT 2 h (2 h PG), glycated hemoglobin (HbA1c), adrenocorticotropic hormone (ACTH) and cortisol were significantly decreased (P<0.05 or P<0.01). The glycated HbA1c had a positive correlation with adrenocorticotropic hormone (ACTH) and cortisol (F). Before and after treatment, the reduced rate of ACTH and reduced rate of cortisol respectively exhibited a positive correlation with the reduced rate of HbA1c, reduced rate of SAS and reduced rate of SDS. ConclusionAnti-anxiety depression treatment can lower blood sugar level in pre-diabetes patients with anxiety and depression significantly, which may be related to the activity of HPA axis.
Objective To systematically evaluate the effectiveness of frequently-used bariatric surgery versus conventional medical therapy for obese patients with type 2 diabetes. Methods Such databases as The Cochrane Library (Issue 12, 2012), PubMed, CNKI, CBM, VIP and WanFang Data were searched to collect the randomized controlled trails (RCTs) about frequently-used bariatric surgery vs. conventional therapy for obese patients with type 2 diabetes. The retrieval time was from inception to May, 2012. Two reviewers independently screened the literature according to the inclusion and exclusion criteria, extracted the data, and evaluated the quality. Then the meta-analysis was performed using RevMan 5.1.2 software. Results A total of three RCTs involving 340 patients were included finally. The results of meta-analysis showed that, compared with conventional medical therapy, bariatric surgery could improve the diabetes remission, decrease both glycated hemoglobin level and patient’s weight. At the same time, the postoperative complications were fairly mild. Conclusion Frequently-used bariatric surgery is superior to conventional medical therapy when treating obese patients with type 2 diabetes, and it deserves to be recommended in clinic. However more studies are required to further confirm this conclusion because of the quality and quantity limitation of the included studies.
