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 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.
Polycystic ovary syndrome (PCOS) affects many women of reproductive age, including ovarian and metabolic dysfunction. Major therapeutic goals include weight loss and improved insulin resistance. The effects of weight loss and increased insulin sensitivity of glucagon-like peptide-1 (GLP-1) receptor agonists provide another opportunity and pathway for the treatment of PCOS patients, especially those with metabolic abnormalities. This paper reviews the metabolism and reproductive outcomes about GLP-1 receptor agonists for PCOS by searching for literatures of clinical trials from PubMed in the past 10 years, in oder to provide new ideas and clinical evidence for clinical treatment of PCOS.
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 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.
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.
Diabetic retinopathy (DR) is one of the most serious complications of diabetes mellitus. Severe diabetic macular edema or proliferative retinopathy may lead to impaired vision or even blindness in diabetic patients. The glucagon-like peptide-1 receptor agonist (GLP-1RA) is now commonly used as novel glucose-lowering agents in the clinical management of type 2 diabetes, but the rapid glycaemic changes associated with the use of the GLP-1RA may aggravate the risk of an increase in the occurrence of short-term potential DR. Potential effects and mechanisms of DR include oxidative stress, vascular endothelial growth factor, inflammation, retinal neurodegeneration, and other cytokines.Whether GLP-1RA leads to the increased risk of DR remains controversial. More basic and clinical studies are needed with the aim of further clarifying the correlation between GLP-1RA and DR risk.
【摘要】 目的 了解不同糖代谢状态的人群空腹及口服葡萄糖耐量实验（oral glucose tolerance test，OGTT）餐后胰高血糖素样态-1（GLP-1）和葡萄糖依赖的促胰岛素多态（GIP）水平。 方法 将受试者根据OGTT结果分为3组:正常糖耐量组（NGT，n=61例），糖耐量受损组（IGT，n=53）和2型糖尿病组（T2DM， n=66）。采空腹及糖餐后2 h静脉血检测GLP-1和GIP水平。 结果 T2DM组空腹GLP-1水平低于NGT和IGT组（Plt;0.05）。NGT和IGT的空腹GLP-1水平差异无统计学意义（Pgt;0.05）。餐后GLP-1水平三组差异无统计学意义（Pgt;0.05）。空腹及餐后GIP水平在NGT、IGT和T2DM均呈逐渐增加的趋势，而且同OGTT-0 h和OGTT-2 h血糖水平呈正相关（r=0.384，0.426；Plt;0.05）。 结论 不同的GLP-1和GIP水平也许是IGT和T2DM胰岛素分泌能力不同的原因之一。【Abstract】 Objective To investigate the fasting, and after oral glucose tolerance test (OGTT), the postprandial levels of glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) in Chinese people with different degrees of glucose tolerance. Methods Based on the results of OGTT, 180 subjects were divided into three groups: normal glucose tolerance group (NGT group, n=61), impaired glucose tolerance group (IGT group, n=53) and type-2 diabetes mellitus group (T2DM group, n=66). Fasting venous blood and the venous blood 2 hours after OGTT was sampled to detect GLP-1 and GIP levels. Results The fasting GLP-1 level in the T2DM group was significantly lower than that in the NGT and IGT groups (Plt;0.05). There was no significant difference in fasting GLP-1 level between NGT and IGT groups (Pgt;0.05). There was no significant difference in GLP-1 level 2 hours after OGTT among all the three groups (Pgt;0.05). GIP level gradually increased in the order of NGT, IGT and T2DM both before and after glucose load, and it was positively correlated with glucose levels just after OGTT and 2 hours after OGTT (r=0.384,0.426;Plt;0.05). Conclusion Different GLP-1 and GIP levels may be one of the reasons for different insulin secretion ability between IGT and T2DM
Objective To evaluate the feasibility of hyperinsulinemic normoglycemia strategy in critically ill patients. Methods Between January 2020 and October 2021, the critically ill patients with stress hyperglycemia in the Emergency Intensive Care Unit of the Fourth People’s Hospital of Langfang were randomly assigned into a trial group or a control group. The trial group adopted hyperinsulinemic normoglycemia therapy, while the control group adopted conventional glucose control therapy. The mean and variability (standard deviation) of blood glucose, incidences of severe hypoglycemia and abnormal hyperglycemia, as well as the percentage of blood glucose values within the target range were compared between the two groups, to evaluate the feasibility of hyperinsulinemic normoglycemia strategy in critically ill patients from the perspective of safety and effectiveness. The non-normally distributed measurement data were presented as median (lower quartile, upper quartile). Results A total of eighty patients were included, with forty cases in each group. The mean blood glucose level [6.00 (5.74, 6.70) vs. 9.51 (8.74, 10.01) mmol/L, P<0.001], the standard deviation of glucose level [1.58 (1.11, 2.15) vs. 2.20 (1.21, 2.76) mmol/L, P=0.028], and the glycemic lability index [175.52 (100.51, 346.69) vs. 408.51 (205.56, 651.91) mmol2/(L2·h·d), P<0.001] were all smaller in the trial group than those in the control group. The percentage of blood glucose values within the target range was 77.34% in the trial group and 5.33% in the control group, respectively, and the difference was statistically significant (P<0.001). No patients experienced severe hypoglycemia. There was a significant difference in the incidence of abnormal hyperglycemia between the two groups (5.08% vs. 36.16%, P<0.001). Conclusions Hyperinsulinemic normoglycemia strategy can effectively and safely provide normoglycemia, reduce glycemic variability, and achieve good glycemic control in critically ill patients. Hyperinsulinemic normoglycemia strategy may be a new approach to glycemic control in critically ill patients.
