ObjectiveTo investigate the association between the stress-induced hyperglycemia ratio (SHR) and all-cause, cardiovascular, and diabetes-related mortality in patients with advanced cardiovascular-kidney-metabolic (CKM) syndrome, and to evaluate the value of SHR as an independent prognostic marker. MethodsThis retrospective cohort study used data from the 1999–2018 U.S. National Health and Nutrition Examination Survey (NHANES). A total of 2 135 patients with advanced CKM (stages 3 and 4) were included. Kaplan-Meier analysis and multivariable Cox regression models were applied to assess the relationship between SHR and mortality outcomes. Restricted cubic spline (RCS) analysis was employed to explore potential non-linear associations. Subgroup analyses were conducted to identify possible effect modifiers. ResultsOver a mean follow-up of 248 months, 674 all-cause, 198 cardiovascular, and 31 diabetes-related deaths occurred. Elevated SHR was significantly associated with diabetes-related mortality (HR=3.48, P<0.001) in a dose-response manner. SHR exhibited a U-shaped relationship with both all-cause and cardiovascular mortality (non-linearity P<0.001), indicating increased risk at both low and high SHR levels. Subgroup analyses revealed that sex, BMI, and hyperlipidemia significantly modified the association between SHR and diabetes-related death. ConclusionSHR is an independent predictor of mortality risk in patients with advanced CKM syndrome, particularly for diabetes-related death. These findings support the integration of SHR into risk stratification of high-risk CKM populations and provide a basis for metabolic stress-targeted interventions.
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.
Obesity is a chronic metabolic disease driven by multiple factors such as genetic susceptibility, environmental factors, and neuroendocrine system disorders. In recent years, the prevalence of obesity in China has been increasing year by year, and a series of obesity-induced diseases are a serious threat to public health. Glucagon-like peptide-1 receptor agonists, as a representative of the new weight loss drugs, have shown a therapeutic effect close to that of weight-loss metabolic surgery in clinical trials by targeting central appetite and metabolism and other synergistic effects, but they still face key problems such as significant differences in individual efficacy, limited evidence of the safety of long-term treatment, and regaining body weight after discontinuation of the drug. The mechanism of action and clinical evidence of several obesity drugs approved and listed in China are summarized, and the progress and challenges of obesity drug therapy in China in combination with recent advances in the development of multi-target agents internationally are discussed, with a view to providing a scientific basis for the clinical drug management of obesity and providing ideas for the research and development of obesity drugs in China as well as for the clinical transformation.
Objective To investigate and analyze the relationships among glucagon-like peptide-1 (GLP-1) level, chronic inflammation, and atherosclerosis in patients with non-alcoholic fatty liver disease (NAFLD). Methods From October 2016 to February 2017, using cross-sectional investigation, the GLP-1 level, chronic inflammation, and atherosclerosis were investigated in 80 subjects (40 NAFLD patients in NAFLD group, and 40 non-fatty liver disease participants in control group) who underwent physical examination at Xi’an Road Community Hospital. Results Compared with those in the control group, GLP-1 fasting level in patients with NAFLD [(9.09±1.03) vs. (9.15±1.06) pmol/L, P=0.807] and postprandial plasma GLP-1 [(15.96±3.37) vs. (17.46±4.76) pmol/L, P=0.108] had no changes. The correlations of GLP-1 level with chronic inflammation and insulin resistance (IR) were not significant either. The increased risk of carotid intima-media thickness related cardiovascular disease (CVD) in the NAFLD group was greater than that in the control group, and the difference was statistically significant [22 (55.0%)vs.13 (32.5%), P=0.043]. When the plasma lipoprotein-associated phospholipase A2 level increased, the risk of NAFLD increased [odd ratio (OR)=1.16, 95% confidence interval (CI) (1.02, 1.32), P=0.023]. Plasma ceramide kinase (CERK) in the NAFLD group was lower than that in the control group, and the difference was statistically significant [(12.36±2.45) vs. (18.33±3.71) ng/mL, P<0.001]. When the plasma CERK level of the fasting plasma was elevated, the risk of NAFLD decreased [OR=0.30, 95%CI (0.12, 0.78), P=0.014]. The homeostasis model assessment of insulin resistance (HOMA-IR) in the NAFLD group was higher than that in the control group, and the difference was statistically significant (2.46±2.53 vs. 1.11±0.66, P=0.002). The Matsuda index in the NAFLD group was less than that in the control group, and the difference was statistically significant (5.88±4.09 vs. 10.46±7.90, P=0.002). When HOMA-IR increased, the risk of NAFLD increased [OR=2.75, 95%CI (2.49, 3.12), P=0.036]. Conclusions Plasma GLP-1 level is not a sensitive indicator of chronic inflammation and IR in patients with NAFLD. Patients with NAFLD are in an increased risk of atherosclerosis and CVD. It suggests that NAFLD might be involved in chronic inflammation and IR. Chronic inflammation can cause IR, and then chronic inflammation and IR can cause NAFLD and subclinical atherosclerosis. In return for this, NAFLD increases chronic inflammation and IR.
Diabetic retinopathy (DR) is one of the most frequent complications of diabetes (T2DM), which is the main eye disease causing blindness in adults in recent years. At present, glucagon-like peptide-1 receptor agonists (GLP-1RA) have become the main drugs used in the treatment of diabetes due to its superior hypoglycemic, lipid-lowering, hypertensive and cardiovascular effects. A large number of studies have shown that GLP-1RA drugs can protect retinal microvascular and optic nerves in the treatment of diabetes through various ways, but some studies have found that GLP-1RA drugs represented by semaglutide may lead to the progress of DR. Therefore, GLP-1RA should be used cautiously for patients who with severe non-proliferative DR or proliferative DR. Regardless of whether T2DM patients are complicated with DR, the fundus retinal condition should be monitored regularly after the use of GLP-1RA drugs, and timely countermeasures should be taken when DR occurs and develops. The benefits of GLP-1RA used by diabetes patients are obvious to all, and scientific and rational drug use can prevent the occurrence and progress of DR, which can better benefit DR Patients.
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 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 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.
ObjectiveTo investigate the clinical symptom and risk factors of diabetic seizures. MethodsThe clinical data of 44 patients with diabetes related seizures were analyzed with the clinical classification, blood glucose, Na+, Plasma Osmotic Pressure, HbA1c, EEG, brain MR, and the antiepileptic drugs. Results① Diabetic hyperglycemia (DH) related seizures: among the 28 patients, 17 cases were male patients, 11 cases were female patients. The mean age was 51.3 years old. Simple partial seizure without secondary generalized seizures (12/28, 42.8%) was the most common, 8 patients (8/28, 28.6%) showed complex partial seizure, 8 patients (8/28, 28.6%) showed no obvious focal origin generalized tonic-closure seizures. Patients with poor glycemic control (HbA1c > 9%) had significantly higher risk of generalized seizures (46.7% vs. 7.7 %, P < 0.05) (P < 0.05). ② Diabetic ketoa-cidosis or hypertonic state associated seizures: among the 7 patients, 6 cases were male patients, 1case was female patients. The mean age was 45.7 years old, 2 patients (2/7, 28.6%) had generalized tonic-clonic seizure, 2 patients (2/7, 28.6%) showed status epilepticus, 2 patients (2/7, 28.6%) showed local motor seizure, 1 patient (1/7, 14.2%) showed Jackson seizure. ③ Diabetic hypoglycemia related seizures: among the 9 patients, 7 cases were male patients, 2 cases were female patients. The mean age was 45.3 years old.5 patients showed generalized tonic-clonic seizure (5/9, 55.6%), 3 patients had complex partial seizure (3/9, 33.3%), 1 patients had generalized tonic-closure seizures (1/9, 11.1%). ConclusionSimple partial seizure is the most common in patients with diabetic hyperglycemia related seizures; so as to diabetic hypoglycemia and keto-acidosis, generalized seizures are relatively common. HbA1c can be an important risk factor of seizures for patients with hyperglycemia.
