Objective To investigate the relationship between serum neutrophil extracellular trapps(NETs)levels and carotid intima-media thickness(CIMT)in patients with type 2 diabetes mellitus(T2DM).Methods A total of 112 newly diagnosed T2DM patients were selected from September 2022 to May 2023.Patients were divided into the T2DM group(T2DM,n=35),T2DM+the intima-media thickening group(CIMT,n=39)and T2DM+the atheromatous plaque group(PLA,n=38)according to the CIMT.And 50 cases of healthy people were selected as the normal control(NC)group in the same period.Results Compared with the NC group,the BMI,SBP,FPG,2 hPG,TC,and NETs increased in the T2DM group(P<0.05);The BMI,SBP,HbA1c,2 hPG,TG,CIMT,HOMA-IR,and NETs were higher in the CIMT group than in the T2DM group(P<0.05),while FPG,TC,and LDL-C were higher in the CIMT group than in the NC group(P<0.05).The SBP,HbA1c,2 hPG,LDL-C,CIMT,and NETs were higher in the PLA group than in the CIMT group(P<0.05),while BMI,FPG,TG,and HOMA-IR were higher in the PLA group than in the T2DM group(P<0.05).Spearman correlation analysis showed that CIMT in T2DM patients was positively correlated with NETs,smoking,BMI,SBP,FPG,2 hPG,HbA1c,LDL-C,TC,TG,UACR and HOMA-IR(P<0.05).Multiple linear regression analysis showed that NETs,HbA1c,LDL-C and TG were independent risk factors for CIMT in the T2DM patients.The analysis of the working characteristic curve of the subjects showed that the area under the curve of serum NETs for diagnosing T2DM combined with AS was 0.960,with sensitivity of 97.4%and specificity of 84.7%.Conclusion Serum NETs are associated with atherosclerosis in T2DM patients.

Objective:To analyze the trend of late-diagnosis of HIV-infected men who have sex with men (MSM) before and after the AIDS Conquering Project in Guangxi Zhuang Autonomous Region (Guangxi) and its influencing factors, in order to find out the population groups that need priority intervention at the present stage.Methods:The HIV-infected MSM in Guangxi from 2005-2021 were selected from the National Integrated HIV/AIDS Control and Prevention Data System. The Joinpoint 4.9.1.0 software was used to test the time trend of late-diagnosis and non-late-diagnosis cases, and logistic regression was applied to analyze the factors influencing the proportion of late-diagnosis at each stage.Results:From 2005 to 2021, 5 764 HIV-infected MSM were reported in Guangxi from 2005 to 2021, with an overall late-diagnosis of 28.45% (1 640 cases). Under the 2015 baseline data as the boundary, the proportion of late-diagnosis cases showed a trend of sharp decline followed by stabilization from 2005 to 2015, average annual percent change= -6.90% ( P<0.001). The effect of factors such as resident population, occupation as a farmer or worker, and sample originating from medical consultation on late-diagnosis changed considerably before and after the implementation of the project, and the factors influencing late-diagnosis at this stage were age, resident population, occupation as a farmer, worker or student. The factors influencing late-diagnosis at this stage are age, resident population, and occupation as a farmer, worker and a student. Conclusions:The proportion of late diagnosis cases of HIV-infected MSM in Guangxi decreased significantly before and after the project. However, late-diagnosis should not be neglected and precise prevention and control should be carried out for the resident population, farmers, workers or students.

Objective:To analyze immune reconstitution and influencing factors in HIV infected men who have sex with men (MSM) with access to antiviral therapy (ART) in Guangxi Zhuang Autonomous Region (Guangxi) during 2005-2021.Methods:The data were collected from Chinese Disease Prevention and Control Information System. The study subjects were HIV infected MSM with access to the initial ART for ≥24 weeks in Guangxi from 2005 to 2021 and HIV RNA lower than the detection limit within 24 months. The proportion of infected MSM who had immune reconstitution after ART was calculated. Cox proportional hazard regression model was used to analyze the influencing factors of immune reconstitution. Software SPSS 24.0 was used for statistical analysis.Results:A total of 3 200 HIV infected MSM were enrolled, in whom 15.56 % (498/3 200) had no immune reconstitution, 14.78% (473/3 200) had moderate immune reconstitution, and the rate of complete immune reconstitution was 69.66% (2 229/3 200). The M ( Q1, Q3) of ART time for immune reconstitution was 12 (5, 27) months. Multivariate Cox proportional risk regression model analysis results showed that compared with those with initial ART at age ≥30 years, WHO clinical stage Ⅲ/Ⅳ illness, baseline BMI <18.50 kg/m 2 and baseline CD4 +T lymphocyte (CD4) counts <200 cells/μl, HIV infected MSM with initial ART at age <30 years, WHO clinical stageⅠ/Ⅱ illness, baseline BMI≥24.00 kg/m 2 and baseline CD4 counts ≥200 cells/μl were more likely to have complete immune reconstitution. Conclusions:In the HIV infected MSM in Guangxi, failures to achieve moderate and complete immune reconstitution were observed. Surveillance and ART regimen should be improved for key populations, such as those with older age and low baseline CD4 counts.

ObjectiveTo explore the psychological defense styles and family environment among male prisoners of different terms of imprisonment， and to analyse the relationship between their psychological defense styles and family environment. MethodsA total of 200 male prisoners in a prison in Guangdong were randomly selected from April to June 2015， and they were classified into less than 5 years of imprisonment group （n=108） and 5 years or more imprisonment group （n=92）. Their defense style and family environment were evaluated by Defense Style Questionnaire （DSQ） and Family Environment Scale-Chinese Version （FES-CV）. Pearson correlation analysis was used to test the correlation between each scale score. ResultsThe factor scores of immature defense mechanism and intermediate defense mechanism of DSQ in the group with less than 5 years of imprisonment were lower than those in the group with 5 years or more imprisonment， with statistically significant differences （t=4.198， 1.137， P<0.01）. The scores of FES-CV family intimacy， emotional expression and organizational factors in less than 5 years of imprisonment group were higher than those in 5 years or more imprisonment group （t=3.122， 2.993， 2.203， P<0.01）， and the scores of contradiction factors were lower than those in 5 years or more imprisonment group （t=-3.682， P<0.01）. The scores of DSQ immature， intermediate defense mechanism and concealment factor of male prisoners were negatively correlated with the scores of FES-CV family intimacy and emotional expression factor （r=-0.428~-0.172， P<0.05 or 0.01）， and the scores of 4 factors in DSQ were all positively correlated with the scores of contradiction factor in FES-CV （r=0.175~0.384， P<0.05 or 0.01）. ConclusionCompared with male prisoners with less than 5 years of imprisonment， those with 5 years or more are prone to adopt immature and intermediate defense mechanisms， and their family environments are characterized by apparent contradiction and a lack of family intimacy， emotional expression and organization. Furthermore， the defects of psychological defense mechanism of prisoners are related to their family environment.
