Objective:To understand the incidence of diabetes and influencing factors, the trend of FPG change and risk for mortality in HIV-infected individuals after antiretroviral therapy (ART) in Dehong Dai and Jingpo Autonomous Prefecture (Dehong).Methods:The HIV/AIDS treatment database was collected from China Information System for Disease Control and Prevention. This retrospective cohort study was conducted in HIV-infected individuals with access to ART in Dehong during 2004-2020.The Cox proportional hazard regression model was used to analyze the incidence density of diabetes, the influencing factors and risk for mortality in HIV-infected individuals with access to ART, mixed linear effects model was used to analyze the trend of FPG change and predict FPG in those with different glucose metabolic status at baseline survey. Statistical analysis was performed using software SAS 9.4.Results:A total of 8 763 HIV-infected individuals were included, in whom 8 432 (96.2%) had no diabetes, 331 had diabetes. The incidence density of diabetes was 2.31/1 000 person years. Multivariate Cox proportional hazard regression analysis revealed that 30- 59 years old, BMI ≥24.0 kg/m 2, Efavirenz (EFV) based initial treatment regimen and impaired fasting glucose (IFG) at baseline survey were significantly and positively associated with incidence of diabetes. Mixed effect model revealed that FPG was positively correlated with the duration of ART, age and baseline FPG. Suffering from diabetes was a risk factor for mortality in HIV-infected individuals both at baseline survey and during follow-up. Conclusions:The risk for diabetes increased in HIV-infected individuals who were 30-59 years old, baseline BMI ≥24.0 kg/m 2, received EFV based initial treatment, and IFG in HIV-infected individuals after antiretroviral therapy in Dehong, 2004-2020. It is important to pay close attention to their blood glucose, and patients with high blood glucose should receive treatment as early as possible.

Objective:To investigate the correlation between miR-137 gene polymorphism and genetic susceptibility to gestational diabetes mellitus.Methods:A total of 500 pregnant women with gestational diabetes who were admitted to Shunde Women and Childrens Hospital of Guangdong Medical University from January 2023 to September 2023 were selected as the observation group, and 500 healthy pregnant women with normal glucose metabolism and no pregnancy complications were selected as the control group. Polymerase chain reaction (PCR) was used to detect rs1625579 polymorphisms of miR-137 gene between the two groups, and the clinical data of the two groups were compared to analyze the influencing factors of the occurrence of gestational diabetes mellitus.Results:The frequencies of GT+ GG genotype and allele G at rs1625579 site of miR-137 gene in observation group were 13.20% and 7.00%, respectively, which were significantly higher than those in control group (all P<0.05). Fasting blood glucose (FPG), fasting insulin (FINS) and insulin resistance index (HOMA-IR) of miR-137 genotype GT+ GG pregnant women in the observation group were (7.92±0.81)mmol/L, (19.92±3.10)mmol/L and 6.60±1.02, respectively. It was significantly higher than genotypic TT pregnant women (all P<0.05), and islet β cell function index (HOMA-β) was significantly lower than genotypic TT pregnant women (188.84±43.34) ( P<0.05). Pre-pregnancy body mass index (BMI) and average weekly weight gain during pregnancy in the observation group were (23.81±1.92)kg/m 2 and (445.50±35.65)g, respectively, which were significantly higher than those in the control group (all P<0.05). The proportion of family history of diabetes in the observation group was 8.60%, which was significantly higher than that in the control group ( P<0.05). Logistic regression analysis showed that preconception BMI and average weekly weight gain during pregnancy were the influential factors for the occurrence of gestational diabetes (all P<0.05). Conclusions:The occurrence of gestational diabetes mellitus has no significant correlation with miR-137 gene polymorphism, but is related to pre-pregnancy BMI and average weekly weight gain during pregnancy. Compared with other miR-137 genotypes, GT+ GG patients were more likely to develop abnormal blood glucose.

Objective To construct a scientific and rational post competency model of human organ donation coordinators. Methods Based on the onion model, the index pool was initially constructed by literature research and behavioral event interview. The index system was screened, modified and improved using Delphi method. The weight of indexes at all levels was determined by analytic hierarchy process. Results The effective response rates of two rounds of Delphi expert inquiries were both 100%, indicating that the expert opinions were highly dependable. The experts' judgment coefficient (Ca), familiarity (Cs) and authoritative coefficient (Cr) were all above 0.7, indicating that the experts' opinions were highly reliable. The expert coordination coefficients (W) were 0.294 and 0.342 (both P<0.001), indicating that experts delivered coordinated opinions and yielded slight difference in understanding the importance of indexes. Finally, according to the "onion model" theory and experts' opinions, a set of coordinator's post competency model including 6 first-level and 55 second-level indexes was established, which comprised an index surface layer, a middle layer and a core layer. Among them, the core layer represented core professional values, the middle layer was personal quality and professional ethics and quality, and the surface layer was interpersonal communication capability, organizational cooperation capability and professional knowledge and lifelong learning capability. Conclusions The post competency model of organ donation coordinators established in this study consists of 6 first-level and 55 second-level indexes, which is highly effective and reliable.
