ObjectiveTo systematically review the effectiveness of breastfeeding duration and intensity in reducing the risk of overweight or obesity among offspring exposed to intrauterine hyperglycemia. MethodsThe PubMed, EMbase, Web of Science, CBM, WanFang Data, CNKI and VIP databases were electronically searched to collect observational studies on the associations of breastfeeding with the risk of overweight or obesity among offspring exposed to intrauterine hyperglycemia from inception to September 25th, 2021. Two reviewers independently screened the literature, extracted data and assessed the risk of bias of the included studies. Stata 16.0 software was used for the meta-analysis. ResultsA total of 12 657 participants from 13 observational studies were included. The results of meta-analysis showed that breastfeeding could reduce the risk of overweight or obesity among offspring exposed to intrauterine hyperglycemia (OR=0.67, 95%CI 0.53 to 0.84, P=0.001). Subgroup analysis revealed a protective effect of breastfeeding for both 1-6 months (OR=0.53, 95%CI 0.37 to 0.75, P<0.001) and ≥6 months (OR=0.56, 95%CI 0.46 to 0.69, P<0.001); however, breastfeeding shorter than one month was suggested to increase the risk of overweight or obesity (OR=2.15, 95%CI 1.41 to 3.27, P<0.001). ConclusionAvailable evidence suggests that breastfeeding for more than one month is effective in reducing the risk of overweight or obesity in offspring exposed to intrauterine hyperglycemia, and women with hyperglycemia should be encouraged to breastfeed their offspring for at least 1 month to achieve the effect. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
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.
Objective To investigate the effects of tight blood glucose control on the shortterm prognosis of the patients after heart valve replacement, in order to improve treatment effectiveness and lower postoperative complications. Methods A total of 240 patients including 150 males and 90 females underwent mitral valve replacement or mitral and aortic valve replacement were enrolled in this study from January 2007 to December 2008 at the cardiac surgery department of Renmin hospital of Wuhan university. The age of these patients ranged from 19 to 65 years old with an average age of 53.33 years. According to insulin administration time and blood glucose control level, they were randomly separated into two groups. In the experimental group, there were 121 patients who received continuous insulin infusion to maintain postoperative glucose level between 4.4 and 6.1 mmol/L, while 119 patients in the control group received insulin infusion when their glucose level went higher than 11.1 mmol/L to control the level between 6.1 and 11.1 mmol/L. Then the postoperative wound infection, malignant arrhythmia rate, the assisted ventilation time, intensive care unit(ICU) stay time and count of neutrophils were compared and analyzed. Results There was no hospitalized death in both groups. The rate of wound infection（3.31% vs.10.08%, χ2=4.430,P=0.035）, the assisted ventilation time（9.02±2.73 h vs. 10.01±3.58 h, t=2.280,P=0.024）, time for count of leukocytes to decrease to the normal level（11.04±3.16 d vs. 12.05±3.76 d, t=2.168,P=0.031）, average hospitalization time（13.49±3.81 d vs. 14.51±4.02 d,t=2.017,P=0.045）, and count of neutrophils on the third day（0.82±0.04 vs. 0.84±0.05, t=2.644,P=0.009） in the experimental group were significantly lower or shorter than those in the control group. But there was no significant difference between both groups in ICU stay time and the rate of malignant arrhythmia. Conclusion Tight blood glucose control can lower the rate of postoperative wound infection, shorten the assisted ventilation time and hospitalization time, and reduce the usage of antibiotics in patients after heart valve replacement. Accordingly, it can enhance the curative effect, reduce overall medical expenses, and improve prognosis.

Objective To observe the feature of post-operative hyperglycemia after coronary artery bypass grafting(CABG) surgery in department of intensive care unit（ICU） patients.Methods Patients who had CABG surgery in Zhongshan Hospital from January 2005 to December 2005 were enrolled.Data were collected including the history of diabetes，pre-operative and post-operative blood glucose(BG) levels，and the time that post-operative hyperglycemia and peak BG occurred.The patients were divided into diabetic and non-diabetic groups according to the diabetic history.The data were compared and analyzed between the two groups.Results 200 patients were enrolled in this study.The incidence of post-operative hyperglycemia was 77%，and about 99.4% occurred in the first 24 hours admitted to ICU，which was independent on diabetic history (χ2=2.58，P=0.108)，but was related to the BG level above 6.1 mmol/L (χ2=12.31，P=0.000).In 80% of the patients，peak BG occurred in the first 24 hours admitted to ICU，which was significantly earlier in the non-diabetic group compared with the diabetic group (8.5 h vs 18.5 h，P=0.02 ).In the patients who had post-operative hyperglycemia，the median time of the BG peak is 10 hours，and 75.3% of the BG peak occurred in the first 24 hours admitted to ICU.Conclusion There is a high incidence of post-operative hyperglycemia in post-CABG patients which always occur within 24 hours after operation and relate to pre-operative high BG.
Objectives To summarize the regulation of glucagon-like peptide-1（GLP-1） level by metabolism of gastrointestinal nutrients. Methods Domestic and international publications online involving regulation of GLP-1 level by metabolism of gastrointestinal nutrients in recent years were collected and reviewed. Results GLP-1 influenced insulin secretion and sensitivity， and played a leading role in recovery of glucose metabolism. Metabolism of gastrointestinal nutrients regulated GLP-1 level. Studies had shown that GLP-1 was a candidate mediator of the effects of gastric bypass （GBP） for type 2 diabetes mellitus（T2DM）. Conclusions It plays an important role in anti-T2DM effects of GBP that metabolism of gastrointestinal nutrients regulated GLP-1 level. The corresponding studies can provide a novel clinical field to treat T2DM.
ObjectiveTo investigate the effect and mechanism of sleeve gastrectomy (SG) on reducing blood glucose level. MethodsThirty GK rats were randomly divided into SG group, sham operation (SO) group, pair-fed (PF) group, and blank control (BC) group. The changes of weight, fasting blood glucose, glucose tolerance (oral glucose tolerance test, OGTT), insulin tolerance (insulin tolerance test, ITT), plasma insulin, ghrelin, and glucagon like peptide-1 (GLP-1) were monitored before and 24 weeks after operation respectively. ResultsFrom the 4th week after operation, weight gain in SG group and PF group began to decrease significantly compared with SO group (Plt;0.01). From the 2nd week after operation, fasting blood glucose level in SG group was lower than that in SO, PF, and BC groups (Plt;005), and the glucose tolerance in SG group obviously improved compared with preoperation and the other 3 groups (Plt;0.01). On the 6th week after operation, the insulin sensitivity in SG group obviously improved compared with SO group (Plt;0.05, Plt;0.01). There was no significant difference of insulin level between SG group and SO group (Pgt;0.05), ghrelin level significantly decreased (Plt;0.01) while GLP-1 level significantly increased (Plt;0.01) in SG group compared with SO group during 2-24 weeks after operation. ConclusionsThe effect of SG on reducing blood glucose is definite. SG can directly lower blood glucose independent with weight loss. Postoperative decreased ghrelin level and increased GLP-1 level may be its primary mechanism.
The risk of cardiovascular disease in patients with type 2 diabetes mellitus is significantly increased, which is the primary cause of death. Recent studies have shown that novel hypoglycemic drugs such as sodium-glucose linked transporter 2 inhibitors and glucagon-like peptide-1 receptor agonists have been proven to have cardiovascular protective effects through cardiovascular outcome trials. This article reviews the improvement effects of these drugs on cardiovascular outcomes and explores their possible mechanisms, such as improving myocardial metabolism and reducing inflammatory reactions, providing a reference for optimizing hypoglycemic regimens.
ObjectiveTo investigate the impact of elevated fasting blood glucose (FBG) level after open radical hepatectomy on the early recurrence of hepatocellular carcinoma (HCC).MethodsThe clinical data of 112 patients with HCC who underwent the open radical hepatecomy from January 2013 to December 2014 in the Affiliated Hospital of Qingdao University were retrospectively analyzed. After the radical resection of HCC, 86 patients with level of FBG 3.9–6.1 mmol/L and 26 patients with level of FBG≥6.1 mmol/L were design into a normal FBG group and an elevated FBG group, respectively. The recurrence rates of HCC were compared between the two groups at 1- and 2-year after the opreation.ResultsThere were no significant differences between the 2 groups in the gender, age, history of alcohol drinking, hepatitis B history, preoperative ALT, AST, AFP and Child-Pugh classification, scope of hepatectomy, intraoperative hemorrhage, hepatic blood flow occlusion, diameter of maximal tumor, histopathological differentiation, tumor number, cirrhosis, satellite lesion, postoperative adjuvant TACE treatment or not (P>0.05). The postoperative 1- and 2-year recurrence rates of HCC were 19.8% (17/86) and 33.7% (29/86) in the normal FBG group and 42.3% (11/26) and 61.5% (16/26) in the elevated FBG group, respectively, showing significant differences between the 2 groups (P<0.05). The results of multivariate analysis showed that the level of FBG≥6.1 mmol/L, low histopathological differentiation, and no postoperative TACE treatment were the independent risk factors affecting tumor-free survival rate after the open radical resection of HCC (P<0.05). ConclusionsElevated FBG level after open radical resection has a stimulative effect on early recurrence of HCC. As a result, monitoring and controlling of FBG level after operation is helpful in decreasing early recurrence rate of patients with HCC.
ObjectiveTo compare the effect of ileal transposition (IT) and Roux-en-Y gastric bypass (RYGBP) on blood glucose and expression of glucagon-like peptide-1 (GLP-1) in Goto-Kakizaki (GK) rats with non-obese type 2 diabetes mellitus (T2DM). MethodsThirty male GK rats were randomized divided into three groups:IT group (n=10), RYGBP group (n=10), and Sham group (n=10). The mortality and complication were observed after surgery. The levels of fasting blood glucose (FBG), fasting insulin (FINS), glycosylated hemoglobin (HbA1c), and GLP-1 were determined before operation, and 1 week, 2 weeks, 1 month, 2 months, 3 months, 6 months after operation in the GK rats of 3 groups. Results① Mortality and morbility. There was no death and complication occurred in IT group and Sham group, only 5 rats of RYGBP group suffered from complication, and 2 of them died. The mortality and morbility were higher in RYGBP group than those of IT group and Sham group (P < 0.05). ② FBG. Compared with before operation in the same group, the FBG levels of IT group and RYGBP group in 1 week, 2 weeks, 1 month, 2 months, 3 months, and 6 months after operation were all lower (P < 0.05). In 1 week, 2 weeks, 1 month, 2 months, 3 months, and 6 months after operation, FBG levels of IT group and RYGBP group were all lower than those of Sham group at the same time point (P < 0.05), but there was no significant difference between IT group and RYGBP group at the 6 time points (P > 0.05). ③ FINS and HbA1c. Compared with before operation in the same group, the FINS levels of IT group and RYGBP group in 3 months and 6 months after operation were higher than those of Sham group (P < 0.05), HbA1c levels of IT group and RYGBP group were both lower at the 2 time points (P < 0.05). In 3 months and 6 months after operation, FINS levels of IT group and RYGBP group were both higher, and HbA1c levels were both lower than corresponding indexes of Sham group at the same time point (P < 0.05), but there was no significant difference between IT group and RYGBP group at the 2 time points (P > 0.05). ④ GLP-1. Compared with before operation in the same group, the GLP-1 levels of IT group and RYGBP group in 1 week, 2 weeks, 1 month, 2 months, 3 months, and 6 months after operation were all higher (P < 0.05). In 1 week, 2 weeks, 1 month, 2 months, 3 months, and 6 months after operation, GLP-1 levels of IT group and RYGBP group were both higher than those of Sham group at the same time point (P < 0.05), but there was no significant difference between IT group and RYGBP group at the 6 time points (P > 0.05). ConclusionIT and RYGBP have a significant hypoglycemic effect on non-obese T2DM GK rats, but IT has lower mortality and morbility, which is more effective and safer, comparing with RYGBP.
