Objective To analyze the characteristics of HIV-1 pretreatment drug resistance(PDR)and molecular transmission networks in Yubei District,Chongqing,providing evidence for targeted interventions.Methods Using a cross-sectional design,plasma samples were collected from HIV/AIDS patients receiving antiretroviral therapy(ART)in Yubei District from January 2022 to December 2023.Pol gene fragments were extracted and amplified for HIV-1 genotyping and drug resistance analysis.Molecular transmission networks were constructed based on genetic distance calculations.Results Among 478 HIV-1 pol sequences,eight geno-types were identified:with CRF07_BC(60.4%,289/478),CRF08_BC(15.5%,74/478),CRF01_AE(11.7%,56/478),and CRF85_BC(5.9%,28/478).The overall PDR rate was 6.3%(30/478),with resistance to nucleoside reverse transcriptase inhibitors(NRTIs)and non-nucleoside reverse transcriptase inhibitors(NNRTIs)at 1.7%(8/478)and 5.2%(25/478),respectively.No protease inhibitor(PI)resistance was de-tected.The molecular network included 177 cases(37.0%network entry rate),forming 53 clusters with 198 connections.Cluster sizes ranged from 2 to 17 nodes,and 75.3%(149/198)of connections were associated with five subdistricts/towns:Shuanglonghu Street,Huixing Street,Luoqi Town,Gulu Town,and Baoshenghu Street.Conclusion HIV-1 genotypes in Yubei District exhibit diversity and complexity,with moderate PDR prevalence.Regional clustering of transmission networks suggests the need for enhanced molecular surveil-lance and targeted interventions based on analytical findings.

Primary aldosteronism(PA)is an important cause of secondary hypertension,and adrenal vein sampling(AVS),as the gold standard for identifying the dominant side in PA,plays a critical role in guiding subsequent therapeutic strategies.AVS is an invasive procedure that is not yet widely available in China.To promote the popularization and standardization of AVS,the Chinese Society of Hypertension(Chinese Research Hospital Association)and the Group of Interventional Diagnosis and Treatment of Hypertension(China International Exchange and Promotive Association for Medical and Health Care)have summarized domestic and foreign evidence and the operational experience of many experts.This consensus has summarized and updated the significance,indications,pre-procedural preparation,procedural steps and key points,prevention and management of complications,and result interpretation of AVS.This consensus provides comprehensive and clinically relevant guidance for the clinical practice and development of AVS,effectively promoting its popularization and standardization.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Aim To investigate the anti-Zika virus(ZIKV)mechanism of diterpenoid compound 9 from Euphorbia helioscopia in vitro.Methods The cytotox-icity of compound 9 was evaluated using the CCK-8 as-say.A ZIKV-infected Vero cell model was established,and the antiviral activity was assessed through RT-qPCR,plaque assay,Western blot,and immunofluores-cence.Furthermore,the mechanism of action was elu-cidated using multi-cell line validation,nanoparticle tracking analysis,cellular thermal shift assay,and mo-lecular docking.Results In Vero cells,compound 9 exhibited an EC50 of(3.95±0.15)μmol·L-1 and a CC50 of(272.12±8.56)μmol·L-1,demonstrating significantly higher antiviral efficacy than the positive control drug ribavirin(RBV).Its virus inactivation effect was time-dependent and could significantly re-duce viral load and plaque formation.Studies revealed that compound 9 altered the physicochemical properties of ZIKV particles,including reducing surface charge and increasing particle size distribution.Additionally,it significantly enhanced the thermal stability of the prM protein.Molecular docking analysis indicated that compound 9 formed a high-affinity interaction with the prM protein(binding energy:-38.52 kJ·mol-1)and stabilized its structure through hydrophobic interac-tions.Conclusion Compound 9 exerts in vitro anti-ZIKV activity by directly inactivating the virus,disrup-ting viral particle integrity,and targeting the prM pro-tein.

Objective:To explore the chain mediating role of positive coping and organizational climate in the relationship between charismatic leadership and clinical nurses' organizational silence behavior.Methods:This study was a cross-sectional research. A convenience sampling method was used to select 236 clinical nurses from the First Affiliated Hospital of Zhengzhou University from April to May 2024. The Conger-Kanungo Charismatic Leadership Scale, Simplified Coping Style Questionnaire (positive coping), Organizational Climate Scale, Nurse Organizational Silence Evaluation Questionnaire were administered to the nurses. Harman's single-factor test was used to examine common method bias, while Spearman's correlation analysis was employed to analyze the relationships among charismatic leadership, positive coping, organizational climate, and organizational silence behavior. The chain mediating effect of positive coping and organizational climate between charismatic leadership and organizational silence behavior was tested using Model 6 in SPSS PROCESS macro.Results:A total of 248 questionnaires were retrieved, with 236 valid responses, yielding an effective response rate of 95.16%. The common method bias test revealed that 7 factors with eigenvalues greater than 1 were extracted, with the first factor explaining 26.19% of the variance, which was below the critical value of 40%. Correlation analysis showed that charismatic leadership, positive coping, and organizational climate were positively correlated with each other ( P<0.05), and organizational silence behavior was negatively correlated with charismatic leadership, positive coping, and organizational climate ( P<0.05). The mediating effect analysis showed that charismatic leadership could directly affect nurses' organizational silence behavior ( β=-0.138, P<0.01), and could also affect nurses' organizational silence behavior through three mediating paths: charismatic leadership→positive coping→nurses' organizational silence behavior, with an effect value of -0.205, accounting for 46.91% (-0.205/ -0.437) of the total effect; charismatic leadership→organizational climate→nurses' organizational silence behavior, with an effect value of -0.073, accounting for 16.70% (-0.073/-0.437) of the total effect; charismatic leadership→positive coping→organizational climate→nurses' organizational silence behavior, with an effect value of -0.021, accounting for 4.81% (-0.021/-0.437) of the total effect. The total mediating effect was -0.299, accounting for 68.42% (-0.299/-0.437) of the total effect. Conclusions:Charismatic leadership not only directly influences nurses' organizational silence behavior but also has an indirect impact through the mediating effects of positive coping and organizational climate.
