ObjectiveTo investigate the effects of single anastomosis sleeve ileal (SASI) bypass on weight loss, metabolic improvements, and postoperative safety in patients with obesity and its metabolic comorbidities (such as type 2 diabetes and hyperlipidemia). MethodsA retrospective analysis was conducted. The clinical data of patients with obesity [body mass index (BMI) ≥32.5 kg/m2 or BMI ≥27.5 kg/m2 with metabolic diseases] who underwent SASI bypass in the Nanjing Drum Tower Hospital Affiliated to Nanjing University Medical School from January 2023 to December 2023. Weight loss outcomes, including the percentage of total weight loss (%TWL), percentage of excess weight loss (%EWL), and percentage of excess BMI loss (%EBMIL), were recorded at 6 and 12 months postoperatively. Metabolic disease remission and complications at 12 months postoperatively were also documented. ResultsA total of 82 patients were included in the study. At 12 months postoperatively, the reductions in %TWL, %EWL, and %EBMIL were significantly greater than those observed at 6 months postoperatively [%TWL: (27.1±4.6)% vs. (23.6±3.8)%, t=2.379, P=0.026; %EWL: (72.1±5.8)% vs. (56.6±7.3)%, t=2.593, P<0.001; %EBMIL: (71.6±6.7)% vs. (58.3±4.9)%, t=2.607, P<0.001], remission was observed in 40 out of 48 patients (83.3%) with comorbid hypertension, 49 out of 51 patients (96.1%) with comorbid type 2 diabetes mellitus, and all patients with comorbid hyperlipidemia (33 cases) and obstructive sleep apnea syndrome (29 cases) achieved complete remission. Within 12 months after SASI bypass, 3 patients (3.7%) experienced melena, 2 patients (2.4%) developed incomplete intestinal obstruction, and 10 patients (12.1%) showed malnutrition. ConclusionThe findings of this study indicate that SASI bypass demonstrates significant weight loss and metabolic improvement effects in patients with obesity and metabolic diseases, with a controllable safety profile.
ObjectiveTo investigate effects of sleeve gastrectomy (SG)-transit bipartition (SG-TB) and simple SG on bariatric and anti-diabetic and protective effect on esophagus reflux. MethodsA total of 36 male Sprague-Dawley rats were used to successfully induce the obesity with type 2 diabetes mellitus (T2DM) model by dietary feeding and receiving intraperitoneal injection of streptozotocin (35 mg/kg), then were randomly averagely divided into SG, SG-TB, and sham operation (SO) groups according to the surgical methods, and 8 rats from each procedure were randomly selected and included to use for experimental observation. The observation period was 12 weeks. The changes of terminal esophageal mucosa were observed at the 12th week after operation. The body weight and food intake were measured every 2 weeks after operation. The fasting blood glucose (FBG), oral glucose tolerance test (OGTT) and insulin tolerance test (ITT) blood glucose levels were measured before operation and at the 4th and 12th week after operation. And the changes of glucagon like peptide-1 (GLP-1) and insulin levels were measured before operation and at the 12th week after operation. ResultsThere were no significant differences in all indexes among the 3 groups before operation (P>0.05). ① No esophageal papillomatosis was observed in the SG-TB group at the 12th week after operation, but more severe esophageal papillomatosis was observed in the SG group, and the mucosal height in the SG-TB group was lower than that in the SG group (P<0.05). ② From the 4th week after operation, the body weight and food intake of the SG-TB group and SG group were lower than the SO group (P<0.05), and their changes of these two groups over time were generally stable. While no significant difference was found in the reduction of body weight between the SG-TB group and the SG group (P>0.05), however the food intakes of the SG-TB group were higher than the SG group at the 10th and 12th week after operation (P<0.05). ③ The levels of FBG, OGTT and ITT blood glucoses in the SG-TB group and SG group were lower than in the SO group at the 4th and 12th week after operation (P<0.05) and remained stable after operation. However, no significant difference was found in the FBG and ITT blood glucose level between the SG-TB group and the SG group (P>0.05), while the level of OGTT blood glucose in the SG-TB group was lower than that in the SG group at the 12th week after operation (P<0.05). ④ The levels of GLP-1 in the SG-TB group and SG group were higher than in the SO group and still higher than before operation (P<0.05), while the insulin levels were lower than in the SO group and lower than before operation (P<0.05). ConclusionsFrom preliminary results of this study, change of terminal esophageal mucosa after SG-TB is weaker than that of SG operation, and it is found that SG-TB surgery shows a better trend in blood glucose control as compared with SG operation. However, due to the limitations of sample size, further research and anti-reflux effect of SG-TB operation still need to be verified.
Objective To explore the relationship between the triglyceride glucose-body mass index (TyG-BMI) and hypertension, type 2 diabetes, as well as their comorbidity, aiming to provide a scientific basis for the early identification and precise prevention of these three diseases. Methods This research collected data from subjects in the China Health and Retirement Longitudinal Study (CHARLS) database. According to the quartiles of TyG-BMI, the included subjects were divided into Q1 group, Q2 group, Q3 group, and Q4 group. Logistic regression was used to analyze the association between the TyG-BMI and the three diseases separately. Further, a restricted cubic spline model was employed to investigate the potential non-linear dose-response relationship between the TyG-BMI index and the three diseases. Subgroup analysis was conducted using interaction tests to investigate whether there was an interaction between TyG-BMI and subgroup factors such as age and gender. Results A total of 4 847 participants were included. There were 1 212 cases in Q1 group, 1 212 cases in Q2 group, 1 211 cases in Q3 group, and 1 212 cases in Q4 group. The logistic regression results indicate that, after adjusting for all confounding factors, participants in the Q4 group had a higher risk of developing type 2 diabetes, hypertension, and comorbidity of hypertension and type 2 diabetes in Model 3 (P<0.05). The results from the restricted cubic spline model demonstrated a linear relationship between the TyG-BMI index and the risk of type 2 diabetes (P for non-linearity >0.05), while a non-linear relationship was observed with hypertension (P for non-linearity <0.05) and the comorbidity of hypertension and type 2 diabetes (P for non-linearity <0.05). Subgroup analysis using interaction tests showed that compared to the Q1 group, factors such as age, gender, smoking, alcohol consumption, and dyslipidemia in the Q2, Q3, and Q4 groups did not significantly alter the relationship between TyG-BMI and type 2 diabetes, hypertension, and their comorbidity. Overall, there was no significant interaction between TyG-BMI and factors like age, gender, smoking, alcohol consumption, and dyslipidemia (P for interaction >0.05). Conclusions In middle-aged and elderly populations, the higher the TyG-BMI, the greater the risk of hypertension, type 2 diabetes, and their comorbidity. The TyG-BMI could be considered an important indicator for the early identification of hypertension, type 2 diabetes, and their comorbidities.
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 the potential molecular mechanism of Rhodiola crenulata (RC) for type 2 diabetes mellitus (T2DM) and Alzheimer’s disease (AD) by network pharmacology and molecular docking. Methods The target genes of T2DM and AD, the effective active components and targets of RC were identified through multiple public databases during March to August, 2022. The main active components and core genes of RC anti T2DM-AD were screened. The key genes were enrichment analyzed by gene ontology function and Kyoto gene and Kyoto Encyclopedia of Genes and Genomes. AutoDock Vina was used for molecular docking and binding energy calculation. Results A total of 5189 T2DM related genes and 1911 AD related genes were obtained, and the intersection result showed that there were 1418 T2DM-AD related genes. There were 48 active components of RC and 617 corresponding target genes. There were 220 crossing genes between RC and T2DM-AD. The main active components of RC anti T2DM-AD included kaempferol, velutin, and crenulatin. The key genes for regulation include ESR1, EGFR, and AKT1, which were mainly enriched in the hypoxia-inducible factor-1 signal pathway, estrogen signal pathway, and vascular endothelial growth factor signal pathway. The docking binding energies of the main active components of RC and key gene molecules were all less than ?1.2 kcal/mol (1 kcal=4.2 kJ). Conclusions RC may play a role in influencing T2DM and AD by regulating the hypoxia-inducible factor-1 signaling pathway, estrogen signaling pathway, and vascular endothelial growth factor signaling pathway.
Objective To construct, validate and evaluate a nomogram prediction model based on triglyceride-glucose index for predicting the risk of type 2 diabetes mellitus (T2DM) in patients with obstructive sleep apnea (OSA). Methods A total of 414 patients diagnosed with OSA who were hospitalized in the Second Affiliated Hospital of Kunming Medical University from July 2013 to July 2023 were retrospectively analyzed. They were randomly divided into training set (n=289) and validation set (n=125) at a ratio of 7:3 using R software. In the training set, univariate logistic regression, best subsets regression (BSR) and multivariate Logistic regression were used to determine the independent predictors of OSA combined with T2DM and construct a nomogram. The area under the receiver operating characteristic curve (AUC), calibration curve, Hosmer-Lemeshow goodness of fit test, decision curve analysis (DCA) and clinical impact curve (CIC) were used to evaluate the discrimination, calibration and clinical applicability of the nomogram prediction model. Finally, the internal validation of the nomogram prediction model was carried out on the validation set. Results In the training set, the results of univariate logistic regression, BSR and multivariate logistic regression analysis showed that hypertension (OR=2.413, 95%CI 1.276-4.563, P=0.007), apnea hypopnea index (OR=1.034, 95%CI 1.014-1.053, P=0.001), triglyceride-glucose index( OR=12.065, 95%CI 5.735-25.379, P<0.001), triglyceride/high density lipoprotein cholesterol (OR=0.736, 95%CI 0.634-0.855, P<0.001) were independent predictors of T2DM in OSA patients. A nomogram prediction model was constructed based on the above four predictors. In the training set and validation set, the AUC, sensitivity, and specificity of the nomogram prediction model for predicting the risk of T2DM in OSA patients were 0.820 (95%CI 0.771-0.869), 75.7%, 75.9% and 0.778 (95%CI 0.696-0.861), 74.5%, 73.0%, respectively, indicating that the nomogram had good discrimination. The calibration curve showed that the nomogram had a good calibration for predicting T2DM in OSA patients. DCA and CIC also showed that the nomogram prediction model had certain clinical utility. Conclusions A simple, fast and effective nomogram prediction model with good discrimination, calibration and clinical applicability was successfully constructed, validated and evaluated. It can be used to predict the risk of T2DM in OSA patients and help clinicians to identify patients with high risk of T2DM in OSA patients.
Objective To investigate the clinical characteristics and pathogen distribution of community-acquired pneumonia (CAP) combined with type 2 diabetes mellitus (T2DM), based on bronchoalveolar lavage fluid (BALF) metagenomic next-generation sequencing (mNGS) test. Methods In this cross-sectional study, CAP patients with BALF mNGS test were screened from April 2023 to April 2024. The patients were divided into a single CAP group (CAP group) and a CAP combine with T2DM group (CAP+T2DM group). The data of demographics, underlying diseases, complications, and laboratory tests including blood routine, inflammatory parameters, liver and renal functions, random blood glucose (RGB), hemoglobin A1C (HbA1c), and BALF mNGS tests were collected and compared between the two groups. Results Ultimately, 86 patients were included, with 45 in the CAP group and 41 in the CAP+T2DM group. Compared with the CAP group, the CAP+T2DM group had higher platelet count [(272.44±128.57)×109/L vs. (215.00±100.06)×109/L], erythrocyte sedimentation rate [(75.63±35.19) vs. (59.69±34.47) mm/h], RGB [10.8 (9.1, 13.5) vs. 6.5 (5.8, 7.8) mmol/L], HbA1c [8.2% (7.3%, 8.5%) vs. 5.7% (5.5%, 6.1%)], and fungi infection rate (65.9% vs. 40.0%), and the differences were statistically significant between the two groups (P<0.05). Conclusion CAP patients with T2DM have increased levels of platelet and erythrocyte sedimentation rate, and are at higher risk for fungi infection, which potentially leads to worse outcome.
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.
