Methods: A total of 109 subjects with the hospitalized diabetes were randomly allocated into two groups: The nutrition group(56 cases) were provided with weighed individual low glycemic index foods and the control group(53 cases) went on diet dominated by themselves. patients in both groups were investigated on meals, diabetic nutrition knowledge and were detected for correlative biochemical indices. Results：After the nutrition treatment, patients biochemical indices of fasting bloodglucose, blood sugar 2 hours after meal, hemoglobin of glycosylation, cholesterol and triglyceride in serum in both groups were significantly lower. Compared with the control group, the effect of the nutrition group was even better. The acknowledgement rate of nutrition knowledge on diabetes of the nutrition group improved significantly, and their meals were more scientifically arranged. Conclusion: The nutrition therapy of low glycemic index foods would be very helpful for type 2 diabetic patients to control their bloodsugar level and improve the nutritional state and outcome.
Objectives To systematically analyze the effect of high-intensity and low-intensity resistance training on glycosylated hemoglobin (HbA1c) in elderly patients with type 2 diabetes. Methods PubMed, EBSCO, Cochrane Library, Web of science, Wanfang, Chinese National Knowledge Infrastructure and Chongqing VIP were searched to collect randomized controlled trials of resistance training intervention in elderly patients with type 2 diabetes. The search time limit was from the establishment of the database to August 28, 2021, and the RevMan 5.3 and Stata 15.0 software were used for meta-analysis. Results A total of 415 patients in 8 articles were included in this study. A subgroup analysis based on control measures showed that compared with the resistance training group, the HbA1c level effect value of the non- training group was weighted mean difference (WMD) = −0.54% [95% confidence interval (CI) (−1.06%, −0.03%), P=0.04)], the HbA1c level effect value of the flexibility training group was WMD=−0.47% [95%CI (−1.05%, 0.12%), P=0.12], the HbA1c level effect value of the aerobic training group was WMD=−0.10% [95%CI (−0.71%, 0.51%), P=0.75]. Subgroup analysis of resistance strength showed that compared with the flexibility or non-resistance training group, both high-intensity [WMD=−0.99%, 95%CI (−1.16%, −0.81%), P<0.00001] and low- and medium-intensity resistance training [WMD=−0.29%, 95%CI (−0.58%, −0.01%), P=0.05] can reduce HbA1c. Compared with the high-intensity resistance training, the HbA1c level effect value of the low- and medium-intensity resistance training was WMD=0.03% [95%CI (−0.33%, 0.39%), P=0.88]. Compared with the low- and medium-intensity resistance training, the HbA1c level effect value of the low- and medium-intensity aerobic training was WMD=−0.10% [95%CI (−0.71%, 0.51%), P=0.75]. Among all the included studies, only the high-intensity resistance training group reported multiple adverse events.ConclusionsCurrent evidence suggests that elderly patients with type 2 diabetes are more suitable to choose low-to-medium-intensity resistance training to control HbA1c. It is recommended that elderly patients with type 2 diabetes take 60% to 75% of the maximum muscle strength of medium-intensity resistance training.
Objective To assess the improvement of different resistance training regimens on blood lipid metabolism and insulin resistance in patients with type 2 diabetes mellitus (T2DM). Methods PubMed, ProQuest, Embase, Web of Science, China National Knowledge Infrastructure, Wanfang, and VIP databases were searched to collect randomized controlled trials of resistance training intervention to improve blood lipids and insulin resistance in patients with T2DM. The search time range was from the establishment of the databases to May 2023. Two reviewers assessed the risk of bias of the included studies using the Physiotherapy Evidence Database scale, and performed a network meta-analysis of the extracted data using Stata 16.0 software. Results In the end, 24 articles were included, and a total of 983 participants were enrolled. The result of network meta-analysis showed that high-frequency and moderate-intensity resistance exercise significantly improved the levels of insulin resistance [standardized mean difference=−1.71, 95% confidence interval (CI) (−2.75, −0.67)], triglycerides [weighted mean difference (WMD)=−0.27 mmol/L, 95%CI (−0.51, −0.04) mmol/L], and total cholesterol [WMD=−0.16 mmol/L, 95%CI (−0.20, −0.12) mmol/L], but had no significant effect on improving the level of high-density lipoprotein [WMD=0.05 mmol/L, 95%CI (−0.02, 0.11) mmol/L] or low-density lipoprotein [WMD=−0.20 mmol/L, 95%CI (−0.42, 0.03) mmol/L]. The results of cumulative probability ranking showed that high-frequency and moderate-intensity resistance exercise was the best in improving insulin resistance, triglycerides, high-density lipoprotein and low-density lipoprotein levels. Conclusion Based on current evidence, high-frequency and moderate-intensity resistance exercise may be the best resistance exercise regimen to improve insulin resistance and lipid metabolism in patients with T2DM.

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.
ObjectiveTo systematically evaluate effect of metformin on prognosis of colorectal cancer patients with type 2 diabetes mellitus (T2DM).MethodsThe PubMed, Embase, Web of Science, Cochrane Library, CNKI, VIP, Wangfang, etc. databases for cohort studies over the past 10 years were systematically searched. The relationship between the metformin and the prognosis in the colorectal cancer patients with T2DM was assessed with RevMan 5.3 software.ResultsA total of 12 articles with 13 694 patients were included in this study, of which 9 069 patients treated by the metformin (metformin group) and 4 625 patients treated by the other antidiabetic agent (control group). The results of meta-analysis showed that the metformin group had higher over survival [HR=0.74, 95%CI (0.66, 0.82), P<0.000 01] and cancer-specific survival [HR=0.77, 95%CI (0.69, 0.86), P<0.000 01] as compared with the control group. The sensitivity analysis of the heterogeneity showed that the research results did not be changed when the study which might cause heterogeneity was excluded. ConclusionMetformin treatment could improve prognosis of colorectal cancer patients with T2DM and improve overall survival and cancer-specific survival.
Sleeve gastrectomy with transit bipartition (SG-TB) was a novel bariatric and metabolic surgery that had received preliminary approval for its effectiveness and safety in reducing weight, improving diabetes, and other metabolic diseases. It showed promising prospects in clinical applications. However, SG-TB also faced some challenges including a small number of cases, insufficient clinical evidence, issues with anastomotic stoma and common channel design, bile reflux, gastroesophageal reflux disease, and malnutrition. Further research is needed to enhance the standardization of SG-TB procedures and provides reference for its wider implementation.
ObjectiveTo investigate the effect of the remnant stomach after gastric bypass (GB) surgery on the weight loss and glucose metabolism in rats with obese and type 2 diabetes mellitus (T2DM).MethodsHigh fat feeding for one month combined with intraperitoneal injection of low-dose streptozotocin was used to induce obese rats with T2DM. Twenty-four rats with obese and type T2DM successfully established were randomly divided into resectional gastric bypass (R-GB) group, GB surgery (GB group), and sham operation (SO) group, eight rats in each group. The weight loss and anti-diabetic effect of the R-GB and GB were compared. Body weight, food intake, and fasting blood glucose (FBG) were measured at week 1 before operation and week 1–8 after the operation. Oral glucose tolerance test (OGTT) and insulin tolerance test (ITT) were performed using tail venous blood at week 1 before operation and on week 8 after operation (at 0, 30, 60, 90, and 120 min). The levels of serum glucagon like peptide-1 (GLP-1), gastrin, insulin, and glucagon at week 1 before operation and at week 8 after operation were detected, meanwhile the homeostasis model assessment insulin resistance (HOMA-IR) index was calculated.Results① The body weight and food intake of the rats in the R-GB group and GB group were lower than those in the SO group after operation (P<0.05) and which were lower than before operation (P<0.05), but the differences were not significant between the R-GB group and GB group after operation (P>0.05). ② The levels of FBG in the R-GB group only at week 1–4 after operation were lower than those before operation (P<0.05), while which in the GB group at week 1–8 after operation were lower than those before operation and were lower than in the SO group (P<0.05), but which in the R-GB group only at week 2–4 after operation were lower than in the SO group and which were higher than that in the GB group from 3 to 8 weeks after operation (P<0.05). ③ The area under receiver operating characteristic curves (AUCs) of blood glucoses of OGTT and ITT and HOMA-IR index at week 8 after operation were lower than those before operation (P<0.05) in the GB group and which were lower than those the other two groups (P<0.05). ④ The AUC of gastrin level at week 8 after operation was lower than that before operation in the R-GB group and which lower than that in the other two groups (P<0.05). The AUC values of insulin and glucagon levels at week 8 after operation were lower than those before operation in the GB group and which lower than those in the other two groups (P<0.05). The AUC of GLP-1 level at week 8 after operation was higher than that before operation in the GB group and which higher than that in the other two groups (P<0.05).ConclusionsGB could remarkably improve glucose metabolism and weight loss in obese rat with T2DM. Gastric remnant gastrectomy following GB has a remarkable anti-diabetic effect, but it doesn’t effect on weight loss.
Objective To explore mechanism of gastric bypass in treating obesity with type 2 diabetes mellitus (T2DM) and its relationship with c-Jun N-terminal kinase (JNK) signaling pathway. Methods The INS-1 cells were divided into 4 groups according to the different treatment: control group (complete medium), high glucose group (30 mmol/L glucose medium), exendin-4 group (high glucose+100 nmol/L exendin-4), and JNK agonist group (high glucose+100 nmol/L exendin-4+JNK agonist). When these cells were cultured on day 7, the cell activity was assessed by the MTT staining. The cell apoptosis was determined by the fluorescence microscopy analysis after the Hoechst/PI staining and flow cytometric assay after the Annexin V-FITC/PI staining. The expressions of the human immunoglobulin binding protein (Bip), CCAAT/enhancer-binding protein homologous protein (CHOP), P-SAPK/JNK, and caspase-3 protein were detected by the Western blot. Results Compared with the control group, the cell activities were significantly decreased (P<0.05), the cell apoptosis rates and the P-SAPK/JNK and caspase-3 protein expression levels were significantly increased (P<0.01) in the high glucose group and the JNK agonist group, but the Bip and CHOP protein expression levels were significantly increased (P<0.01) in the high glucose group. Compared with the high glucose group, the cell activity was significantly increased (P<0.05), the cell apoptosis rate and the Bip, CHOP, P-SAPK/JNK, and caspase-3 protein expression levels were significantly decreased (P<0.01) in the exendin-4 group, the Bip and CHOP protein expression levels were significantly decreased (P<0.01) in the JNK agonist group. Compared with the exendin-4 group, the cell activity was significantly decreased (P<0.05), the cell apoptosis rate and the P-SAPK/JNK and caspase-3 protein expression levels were significantly increased (P<0.01) in the JNK agonist group. Conclusion Gastric bypass can inhibit endoplasmic reticulum stress of pancreatic islet β-cells by regulating secretion of glucagon like peptide-1, thereby inhibiting JNK signaling pathway, protecting pancreatic islet β-cells and inhibiting apoptosis, so as to achieve effect of treating T2DM.
ObjectiveTo observe expressions of E3 ubiquitin ligase—mitsugmin53 (MG53) protein, MG53 mRNA, and insulin receptor substrate 1 (IRS-1) mRNA in skeletal muscle of non-obese type 2 diabetic mellitus (T2DM) rats after gastric bypass operation (GBP), and to investigate possible mechanism of GBP in improving insulin resistance.MethodsTwenty-four healthy male GK rats were randomly divided into diabetic operation group, diabetic sham operation group, and diabetic control group, 8 rats in each group; besides, 8 male Wistar rats were served as normal control group. The expressions of MG53 protein in skeletal muscle tissue were detected by using Western blot method on week8 after operation. The mRNA levels of IRS-1 and MG53 in skeletal muscles tissue were measured by RT-PCR methods on week 8 after operation.Results① The expressions of MG53 protein and MG53 mRNA in the diabetic sham operation group and diabetic control group were significantly higher than those in the diabetic operation group and the normal control group on week 8 after operation (P<0.05), respectively, which had no significant differences between the diabetic operation group and the normal control group (P>0.05), and between the diabetic sham operation group and the diabetic control group (P>0.05) on week 8 after surgery. ② Compared with the normal control group, the expression of IRS-1 mRNA was significantly decreased in the diabetic operation group, the diabetic sham operation group, and the diabetic control group (P<0.05), while there were no significant differences between the diabetic operation group, diabetic sham operation group, and the diabetic control group on week 8 after operation (P>0.05).ConclusionExpression of E3 ubiquitin ligase—MG53 protein in skeletal muscle tissue in T2DM rats following GBP is decreased, thus reduces the IRS-1 ubiquitin-degradation, increase the expression of IRS-1 protein in insulin signaling pathway of skeletal muscle tissue, and improve insulin resistance of skeletal muscle.
