Objective To investigate the relationship between angiotensin Ⅱ and pancreatic islet β cell secretion function under different glucose tolerance statuses. Method Forty-two patients with newly diagnosed type 2diabetes mellitus ( DM group), 38 subjects with impaired fasting glucose/impaired glucose tolerance ( IFG/IGTgroup) ,and 40 normal control subjects (NGT group) underwent intravenous glucose tolerance test. Fasting plasma angiotensin Ⅱ ( Ang Ⅱ ) and adiponectin were assayed by ELISA. Acute insulin response from 3 to 10 min( AIR3-10 ),the area under the curve( AUCⅠ ) and the peak concentration of the first-phase ( 0-10 min) insulin secretion, the area under the curve of the second-phase( 10-120 min) insulin secretion( AUCⅡ), homeostasis model assessment for β cell function index(HOMA-β) and homeostasis model assessment for insulin resistance index(HOMA-IR) were calculated to explore the relationship with Ang Ⅱ. Result ( 1 ) The levels of Ang Ⅱ in DM group and IFG/IGT group were significantly higher than that in NGT group( P＜0.05 ). The AIR3-10, AUCⅠ and peak concentration, AUCⅡ ,adiponectin in DM group and IFG/IGT group were significantly lower than those in the NGT group ( P＜0. 05), and these results were more significantly reduced in DM group compared with those in IFG/IGT group. (2) Ang Ⅱ was negatively correlated with AIR3-10, AUCⅠ and the peak concentration, AUCⅡ, adiponectin, HOMA-β ( P＜0. 01 ), and positively correlated with fasting blood glucose,2 h blood glucose after glucose loading, fasting insulin, HOMA-IR (P＜0. 05 ). (3)Multiple stepwise regression analysis showed that Ang Ⅱ was independently associated with AUCⅠ and AUCⅡ.Conclusion Ang Ⅱ was an independent factor that affected the insulin secretion function of pancreatic islet βcells. Ruling out the effect of blood pressure, body position, drugs, and other factors, high levels of Ang Ⅱ could predict the dysfunction of pancreatic islet β cell as well as insulin resistance in patients with type 2 diabetes.

The relationship between oxidative stress and the first-phase of pancreatic β cell insulin secretion in subjects with different statuses of glucose tolerance was explored. Fasting adiponectin, 8-hydroxydeoxyguanosin ( 8-OHdG), malondialdehyde ( MDA ), superoxide dismutase ( SOD ), insulin area under the curve ( AUC ) from 0 to 10 min, and AIR3-5 were measured. The levels of oxidative stress-related markers were elevated, the activities of superoxide dismutase,adiponectin, and first-phase of insulin secretion were reduced with the disease progression. MDA and 8-OHdG were negatively correlated with adiponectin, homeostasis model assessment β cell function index ( HOMA-β ),AUC ,and AIR3-5. SOD was positively correlated with adiponectin, HOMA-β, AUC, AIR3-5. The plasma 8-OHdG and SOD were independently associated with AIR3-5. Oxidative stress exerts a significant effect on the first phase of pancreatic β cell insulin secretion, which may contribute to the pathogenesis of type 2 diabetes.

Objective To conduct an epidemiological survey of common congenital heart disease(CHD)among children in ethnic minority areas in southeastern Guizhou and to explore the influencing factors of delayed medical treatment.Methods From January 2019 to July 2022,18 850 children aged 3 months to 14 years in Qiandongnan Miao and Dong Autonomous Prefecture were selected;105 children with CHD were included in the training set,and they were divided into delayed group(80 cases)and non-delayed group(25 cases)according to whether or not to delay medical treatment.In addition,children with CHD(35 cases)from July 2022 to December 2022 were included in the validation set.The general data of the subjects in the two groups were compared and ana-lyzed.Multivariate logistic regression was performed and risk scoring model was constructed.Results The preva-lence of CHD in 18 850 children was 5.57‰(105/18 850),with the highest prevalence in Liping County,and the lowest in Huangping County.The proportion of children with secondary atrial septal defect was the highest,and that of the aortic valve malformation was the lowest.Among the complex cases of CHD,the proportion of children with single type was the highest,and that of children with three or more types were the lowest.Among children with CHD,the rate of delayed medical treatment was 76.19% (80/105).The median delay in medical treatment was 12 months,with an average of(18.78±4.77)months.Multifactor logistic regression analysis showed that heart murmur(level 2～3),less-educated(primary and secondary school)guardian,family per capita income<2 000 yuan,and frequent drinking of the guardian were independent risk factors for delayed medical treatment(P<0.05),and commercial settlement of medical expenses was independent protective factor(P<0.05).Risk scoring model divided the children into three groups:low risk(≤80 points),medium risk(>80 points and≤134 points)and high(>134 points)risk group.The evaluation of the model show that it was accurate,effective,safe,and reliable.Conclusion The highest prevalence is observed in Liping County.The proportion of children with secondary atrial septal defect and the proportion of children with single type are the highest.Delayed medical treat-ment is found in most of the children with CHD.Cardiac murmur,education background of the guardian,per capita family income,guardian alcohol consumption,and medical expense settlement method are all independent influencing factors for delayed medical treatment.

Objective To evaluate the effect of different operation methods on the early swallowing function in the patients with laryngocarcinoma.Methods A total of 138 patients with the first time of open laryngectomy in this hospital from January 2021 to December 2022 were selected as the research subjects by convenience sampling method.The patients were divided into the vertical laryngeal resection group(vertical group,n=34),horizontal laryngeal partial resection(horizontal group,26 cases),suprachloroid laryngeal par-tial resection annular hyoid epiglottis fixation group(SCPL-CHEP group,n=26)and total laryngeal resection group(total laryngeal group,n=52)according to the operation methods.The Anderson Dysphagia Scale,Syd-ney Dysphagia Scale and modified swale drinking water test were used to evaluate the swallowing function on the first day of postoperative oral feeding in the patients.Results The total scores and scores of various di-mensions of the Chinese version of Anderson Dysphagia Scale,total scores and scores of various dimensions of Sydney Swallowing Scale and the results of the modified swale drinking water test had statistical differences a-mong the various groups(P＜0.01);the above indexes had statistical difference between the total laryngeal group and the other groups(P＜0.01),but the above indexes had no statistical difference between the two groups in the horizontal group,vertical group and SCPL-CHEP group(P＞0.05).Conclusion In the patients with laryngeal cancer undergoing open laryngectomy,the dysphagia is less severe during early eating after to-tal laryngectomy,which has little impact on life.

Objective:To explore the effects of swallowing rehabilitation training on swallowing function and quality of life in patients after laryngectomy.Methods:Randomized controlled trials on the effects of swallowing rehabilitation training on swallowing function and quality of life in postoperative laryngeal cancer patients were electronically retrieved from the Cochrane Library, PubMed, Embase, Web of Science, CINAHL, China National Knowledge Infrastructure, WanFang Data, VIP, and China Biology Medicine disc. The search period was from database establishment to February 1, 2024. The quality evaluation criteria for randomized controlled trials of Joanna Briggs Institute Evidence-Based Health Care Center (2016) was used to evaluate the included literature. RevMan 5.3 software was used for meta-analysis.Results:A total of ten articles were included, with 987 patients. Meta-analysis showed that swallowing rehabilitation training could improve the swallowing function ( P<0.01) and quality of life ( P<0.01) of patients after laryngectomy. Conclusions:Swallowing rehabilitation training can improve patients' swallowing function and quality of life after laryngectomy and is worth applying in clinical practice.
