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.
Objective To assess the influence of different digestive tract reconstruction on the blood glucose of gastric antral cancer patients with type 2 diabetes. Methods The clinical data of 51 cases of gastric antral cancer with type 2 diabetes treated radical surgery in this hospital from January 2006 to January 2012 were analyzed retrospectively. The patients were divided into three groups according to the different digestive tract reconstruction methods：BillrothⅠ anastomosis group （n=14）， BillrothⅡ anastomosis group （n=28）， and Roux-en-Y anastomosis group （n=9）. The indexes were analyzed and compared among three groups：① The levels of fast blood glucose （FBG） and 2h postprandial blood glucose （PG2h） were detected before operation and on 1 month and 6 months after the operation；② The level of glycated hemoglobin （HbA1c） was detected before operation and 6 months after the operation；③ The diabetes control was observed. Results The FBG and PG2h levels in the BillrothⅠ anastomosis group detected on 1 month and 6 months after the operation were not statistically different from those detected before the operation （P＞0.05）. The FBG and PG2h levels in the BillrothⅡanastomosis group and Roux-en-Y anastomosis group detected on 1 month and 6 months after the operation were significantly lower than those before the operation respectively （P＜0.05）. The FBG and PG2h levels in the BillrothⅡ anastomosis group detected on 1 month and 6 months after the operation were not statistically different from those in the Roux-en-Y anastomosis group respectively （P＞0.05）， but which were markedly lower than those in the BillrothⅠ anastomosis group， the differences were statistically significant （P＜0.05）. The HbA1c levels in the BillrothⅠ anastomosis group detected before the operation and on 6 months after the operation were not statistically different from each other （P＞0.05）. The HbA1c levels in the BillrothⅡ anastomosis group and Roux-en-Y anastomosis group detected on 6 months after the operation were markedly lower than those before the operation and the difference was statistically significant （P＜0.05）. On 6 months after the operation， the HbA1c levels in the BillrothⅡanastomosis group and Roux-en-Y anastomosis group were markedly lower than those in the BillrothⅠ anastomosis group and the differences were statistically significant （P＜0.05）；the HbA1c level was not statistically different between the BillrothⅡ anastomosis group and the Roux-en-Y anastomosis group （P＞0.05）. The total curative effects in the BillrothⅡ anastomosis and Roux-en-Y anastomosis groups were significantly better than those in the BillrothⅠ anastomosis group （P＜0.05）. Conclusion According to our limited clinical data， BillrothⅡ anastomosis and Roux-en-Y anastomosis for gastric antral cancer patients with type 2 diabetes may be the best surgical approach.
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.

Methods Thirty-eight children with respiratory infection combined with febrile convulsion and 42 children with single respiratory infection diagnosed between June 2009 and December 2010 were selected as the observation group and control group, respectively. Serum electrolytes and blood glucose concentration were assayed and compared between the two groups. Results The concentrations of serum sodium and chloride were (133.05 ± 1.74) mmol/L and (100.37 ± 1.79) mmol/L in the observation group, while (142.19 ± 1.85) and (104.57 ± 1.55) mmol/L in the control group; the differences between the two groups were significant (Plt;0.01). The concentrations of blood glucose were (6.93 ± 0.87) mmol/L in the observation group and (5.12 ± 0.55)mmol/L in the control group; the difference was significant (Plt;0.01). After the treatment, the serum concentrations of sodium and chloride were (140.89 ± 2.68) and (103.29 ± 1.94)mmol/L in the observation group, which were higher than those before treatment (Plt;0.01). After treatment, the blood glucose concentration was (5.31 ± 0.68）mmol/L in the observation group, which was lower than that before the treatment (Plt;0.01). Conclusion Hyponatremia, low serum chlorine and hyperglycemia occurre in the febrile convulsion in children, which should be corrected in the treatment of febrile convulsion.
The use of non-invasive blood glucose detection techniques can help diabetic patients to alleviate the pain of intrusive detection, reduce the cost of detection, and achieve real-time monitoring and effective control of blood glucose. Given the existing limitations of the minimally invasive or invasive blood glucose detection methods, such as low detection accuracy, high cost and complex operation, and the laser source's wavelength and cost, this paper, based on the non-invasive blood glucose detector developed by the research group, designs a non-invasive blood glucose detection method. It is founded on dual-wavelength near-infrared light diffuse reflection by using the 1 550 nm near-infrared light as measuring light to collect blood glucose information and the 1 310 nm near-infrared light as reference light to remove the effects of water molecules in the blood. Fourteen volunteers were recruited for in vivo experiments using the instrument to verify the effectiveness of the method. The results indicated that 90.27% of the measured values of non-invasive blood glucose were distributed in the region A of Clarke error grid and 9.73% in the region B of Clarke error grid, all meeting clinical requirements. It is also confirmed that the proposed non-invasive blood glucose detection method realizes relatively ideal measurement accuracy and stability.
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 investigate the effect and mechanism of gastric bypass surgery (GBP) on fasting bloo-glucose (FBG) in type 2 diabetic rats. MethodsThe models of type 2 diabetic rats were induced by stretozotocin and 20 diabetic rats were randomly divided into two groups: diabetes-operation group (DO group, n=10) and diabetes-control group (DC group, n=10). Another twenty normal rats were randomly divided into two groups: normaloperation group (NO group, n=10) and normal-control group (NC group, n=10). The rats underwent GBP in DO group and NO group and sham operation in DC group and NC group. The FBG levels, serum dipeptidyl peptidase Ⅳ (DPPⅣ), and glucagon-like peptide-1 (GLP-1) concentrations of rats in each group were detected before operation and at 72 h, on 1 week, 4 weeks, and 8 weeks after operation. ResultsThe FBG levels of rats before operation were not significantly different between DO group and DC group or between NO group and NCgroup (Pgt;0.05). After operation, the FBG levels of rats in DO group gradually declined, reached the bottom on 4 weeks after operation and rose slightly on 8 weeks; The FBG levels of rats in DO group were lower after operation than before operation (Plt;0.05); After operation the FBG levels of rats in DO group were higher than that in NO group and NC group at the same time point (Plt;0.05); In DC group, the difference of FBG levels of rats at different time point was not statistically significant (Pgt;0.05); The inter-group and intra-group difference of FPG levels of rats for NO group and NC group was not statistically significant (Pgt;0.05). The concentrations of serum DPP-Ⅳ of rats before operation were not significantly different in each group (Pgt;0.05). After operation, the concentrations of serum DPP-Ⅳ of rats in DO group and NO group gradually decreased and markedly lower than that before operation, respectively (Plt;0.05). The concentrations of serum DPP-Ⅳ of rats after operation in DO group and NO group were significantly lower than that at the same time point in DC group and NC group, respectively (Plt;0.05); The intragroup difference of serum DPP-Ⅳ concentrations of rats for DC group and NC group was not statistically significant (Pgt;0.05). The concentrations of serum GLP-1 of rats before operation were not significantly different between DO group and DC group or between NO group and NC group (Pgt;0.05). After operation, the concentrations of serum GLP-1 of rats in DO group and NO group gradually increased, reached the top on 4 weeks after operation and declined slightly on 8 weeks; The concentrations of serum GLP-1 of rats in DO group and NO group were higher after operation than before operation (Plt;0.05);After operation, the concentrations of serum GLP-1 of rats in NO group were higher than that in NC group (Plt;0.05), but the concentrations of serum GLP-1 of rats at different time point in NO group were not different (Pgt;0.05). The intragroup difference of serum GLP-1 concentrations of rats for DC group and NC group was not statistically significant (Pgt;0.05). ConclusionsThere is obvious hypoglycemic effect of GBP on FBG levels of type 2 diabetic rats other than normal rats, in which high secretion of GLP-1 and low secretion of DPP-Ⅳ may be play an important role.

Methods：The Pro12Ala polymorphism in PPARγ2 was determined by polymerase chain reactionrestriction fragment length polymorphism (PCRRELP) in 177 subjects with primary hypertension of the Han people in Chengdu of China, including 65 subjects with fasting blood glucose (FBG)lt;5.6 mmol/L and 112 subjects with FBG≥5.6 mmol/L; the clinical characteristics including height, weight, OGTT(0h and 2h) of the subjects were detected and the realationship between the Pro12Ala polymorphism and the clinical characteristics were analysed. Results: The allele frequencies in the group with FBGlt;5.6 mmol/L and FBG≥5.6 mmol/L were 0.333, 0.602 for Pro and 0.034, 0.031 for Ala. The genotype frequencies were 0.299, 0.571 for PP and 0.068, 0.062 for PA, and there was no AA. In the group with BMIlt;25, the Pro12Ala polymorphism was associated with FBG （P=0.029). the Ala allele had a negative relationship to the FPG and insulin resistance index (IRI) (Plt;0.05).Conclusion: The data showed that the Pro12Ala polymorphism was associated with FBG., and The allele Ala probably had benefits to glycometabolic disturbance in patients with primary hypertension by declining insulin resistance.
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.
ObjectiveTo recognize the convulsion caused by hypoglycemia, and to analyze its genotype and clinical phenotype, so as to deepen the understanding of hyperinsulinemia.MethodFull exon detection were performed on 2 children with hypoglycemia and convulsions, who had been treated with antiepileptic drugs for 1 year in pediatric neurology department, Henan Provincial People’s Hospital in 2012 and 2014 respectively, but with poor curative effect.ResultABCC8 gene mutations were found in a child. The mutations located in Chromosome 11, with the nucleic acid changes of c.4607C>T (exon38) and the amino acid change of p.A1536V, rs745918247. The inheritancemode of ABCC8 gene could be autosomal dominant or autosomal recessive inheritance. Both of the parents were wild type on this genelocus. The gene mutation is associated with type 1 familial hyperinsulinemic hypoglycemia/nesidioblastosis. The other child was carrying GLUD1 gene mutation, witch is located in chromosome 10, with the nucleic acid changes of c.1498G>A (exon12) and the amino acid change of p.A500T. The inheritance mode of GLUD1 gene is autosomal dominant andthe child’s parents were both wild type. This gene mutationis associated with type 6 familial hyperinsulinemic hypoglycemia/nesidioblastosis. The 2 mutations have not been reported, which are new mutations.ConclusionMutations in these 2 gene loci may be the underlying cause of hypoglycemic convulsions, and are the best explanation for the poor convulsionscontrol of antiepileptic drugs.
