ObjectiveTo investigate the trend and influencing factors of newly reported human immunodeficiency virus (HIV) positivity rate among men who had sex with men (MSM) in Shanghai from 2021 to 2024, and to provide evidence for formulating scientific prevention and control measures of AIDS. MethodsMultiple rounds of cross-sectional questionnaire surveys were conducted among MSM by Shanghai Qing’ai Health Promotion Center. Pearson and Cochran-Armitage trend χ² tests were used to analyze the differences and changes in population characteristics and newly reported HIV positivity rates. A logistic regression model was applied for multivariate analyses of factors associated with newly reported HIV positivity. ResultsA total of 1 653 MSM who had not been previously diagnosed with HIV infection were surveyed. The newly reported HIV positivity rates in 2021, 2023, and 2024 were 7.87%, 3.91%, and 3.06%, respectively, showing a decreasing trend (χ²_trend=13.460, P_trend<0.001). Multivariate analyses revealed that MSM aged 18‒<25 years, residing locally for <1 year, identifying as bisexual, lacking HIV knowledge, and having ≥10 same-sex partners in the past 6 months exhibited higher newly reported HIV positivity rates. Conversely, MSM knowledgeable about HIV prevention, residing locally for 1‒5 years, and engaging in oral sex with male partners in the past 6 months demonstrated lower HIV positivity rates. Annual analyses revealed that MSM with HIV knowledge had lower newly reported HIV positivity rates in 2023 and 2024 (aOR=0.300, 95%CI: 0.811‒0.111; aOR=0.202, 95%CI: 0.085‒0.483). ConclusionThe newly reported HIV positivity rate among MSM in Shanghai from 2021 to 2024 showed a decline. Future interventions should focus on young and mobile MSM, strengthen HIV knowledge education through platforms such as the internet, promote safe sexual behaviors and regular testing, and further expand the coverage of pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) to control HIV transmission within this population.

BACKGROUND: The incidence of leptomeningeal metastasis (LM) in patients with advanced non-small cell lung cancer (NSCLC) is increasing gradually. However, it poses therapeutic challenges due to limited effective interventions. Intrathecal Pemetrexed (IP) holds broad application prospects in the therapeutic domain of LM. This study aims to evaluate the efficacy, safety, and optimal combination strategies of IP in NSCLC-LM patients with epidermal growth factor receptor (EGFR) mutation-positive status, with the aim of providing real-world data support for exploring more precise personalized treatment strategies for these patients. METHODS: 104 EGFR-mutated NSCLC-LM patients who received IP treatment at Affiliated Nanjing Drum Tower Hospital of Nanjing University Medical School from January 2018 to June 2024 were analyzed retrospectively. Clinical parameters, treatment regimens, and survival outcomes were collected. The overall survival (OS), progression-free survival (PFS), clinical response rate and adverse events (AEs) were evaluated. RESULTS: The cohort demonstrated a median PFS of 9.6 months and OS of 13.0 months with 6-month and 1-year OS rates of 80.8% and 56.5%, respectively. Clinical response was observed in 77.9% of patients. The common AEs were myelosuppression (58.7%) and elevation of hepatic aminotransferases (25.0%). Nine (8.7%) patients experienced grade 4 myelosuppression and recovered to normal after receiving symptomatic treatment. Subgroup analyses revealed prolonged OS in patients with Karnofsky performance status (KPS) ≥60 versus <60 (14.4 vs 9.0 months, P=0.0022) and those receiving Bevacizumab therapy versus not (19.2 vs 10.5 months, P=0.0011). CONCLUSIONS IP exhibits promising efficacy and manageable toxicity in EGFR-mutated NSCLC-LM patients. When combined with Bevacizumab, it exerts synergistic antitumor effects with the potential to further improve clinical outcomes.

ObjectiveTo investigate the epidemiological feature of Mpox infection and genetic characteristics of Mpox viruses (MPXVs), so as to understand the etiological evolution of the pathogen. MethodsThe cases infected with MPXVs were originated from Changning District, Shanghai from July 20 to August 24 in 2023. Epidemiological investigations were conducted, and throat swabs, anal swabs, or vesicle fluid were collected for MPXVs nucleic acid testing. High-throughput sequencing was performed using Miniseq of the Illumina sequencing platform, and thereafter the sequences were concatenated and analyzed using the online analysis tool Nextclade. An evolutionary tree was constructed using the MEGA 11 software. ResultsAll 8 cases were male, with an average age of (35.76±7.00) years. Among them, 6 cases were identified through active hospital visits, and 2 cases were discovered during contact tracing for Mpox cases. Within the 21 days preceding the disease onset, all cases had male-male sexual behaviors, and the incubation period ranged from 6 to 10 days. 3 cases had a history of sexually transmitted diseases (STDs). MPXVs nucleic acid testing indicated that the detection rate of MPXVs was found to be 25.00% for throat swabs, 87.50% for anal swabs, and 100.00% for vesicle fluid, with statistically significant differences (χ²=11.052, P=0.004). Sequencing analyses using the online tool Nextclade indicated that all 8 MPXVs belonged to the West African clade Ⅱb, 4 MPXVs were classified as C.1 sub-lineages, and 4 MPXVs were identified as C.1.1 sub-lineages. Phylogenetic analysis using MEGA 11 indicated that 5 MPXVs were classified as Lineage C.1.1, closely related to the prevalent strains in Portugal and other European regions. ConclusionThe MPXVs sequences from Changning District are clssified into clade Ⅱb, lineage C.1.1. The detection rates of vesicle fluid and anal swabs for MPXVs are significantly higher than that of throat swabs.

Objective:To investigate community residents' utilization preferences for "Internet + Nursing Service" and provide evidence for improving service uptake.Methods:Based on literature review, semi-structured interviews, and expert consultation, six service attributes and their levels were identified. Using a discrete choice experiment, 12 choice sets were generated through orthogonal design. Convenience sampling was employed to recruit 294 community residents in Nanjing from January to October 2024. A structured questionnaire was administered, and a conditional logit model was used to explore residents' preferences for "Internet + Nursing Service".Results:A total of 294 questionnaires were distributed, and all were validly returned, with an effective response rate of 100.0%. Preference analysis revealed that nurse type, service continuity, hospital classification, medical insurance coverage, and service price significantly influenced residents' preferences for "Internet + Nursing Service" ( P<0.05). Relative importance analysis indicated that the most valued attributes, in descending order, were medical insurance coverage (41.7%), nurse type (17.9%), service price (12.7%), hospital classification (12.1%), service continuity (11.7%), and waiting time (3.9%). When the proportion of medical insurance coverage reached 80%, residents' willingness to pay was the strongest. Conclusions:Medical insurance coverage is the key factor affecting community residents' choice of "Internet + Nursing Service". Residents prefer services provided by general hospitals and expert nurses. It is recommended to improve medical insurance and pricing policies, allocate resources precisely, and enhance service quality to promote the development of "Internet + Nursing Service".

Objective To give references for future study,the current state of research and identify key areas of interest,and development trends in the field of Chinese Materia Medica interventions for PD were examined.Methods Literature on Chinese Materia Medica treatment of PD published between 2004 and 2024 was retrieved from the China National Knowledge Infrastructure(CNKI)and Web of Science(WOS)databases.After screening,689 articles were included(412 in Chinese,277 in English).CiteSpace software was used for bibliometric and knowledge graph analysis,generating author collaboration networks,institutional collaboration networks,keyword clustering,timeline maps,and keyword burst analysis.Results Over the past two decades,the number of publications has continued to grow globally.Chinese-language studies focused primarily on clinical research,with core authors such as Yi Liu,Jiancheng He,and Jianfen Liang,and institutions like Guangxi University of Chinese Medicine making significant contributions.English-language literature emphasized mechanistic studies,with Kyung Hee University and Beijing University of Chinese Medicine as leading research teams.High-frequency keywords included"Parkinson's disease"(346 occurrences),"traditional Chinese medicine(TCM)"(60 occurrences),and"oxidative stress"(11 occurrences).Keyword clustering revealed research hotspots in TCM formulas(e.g.,Zhichan decoction),mechanisms(e.g.,oxidative stress),and integrated TCM-Western medicine therapies(e.g.,Madopar).Burst analysis indicated emerging frontiers in the gut-brain axis,iron metabolism,molecular docking,gut microbiota,and signaling pathways.Conclusions Although there is a lot of potential for treating PD in TCM,there are also a lot of challenges.In order to realize the transformation of TCM from a supportive to a mainstream treatment for PD,and to bring better efficacy to patients in the future,it is necessary to strengthen evidence-based research,deepen the research of mechanisms,promote the construction of standards,explore the integration of Chinese and Western medicine,and improve the evaluation system.

Objective:To explore the relationship between the dark triad, fear of missing out and smartphone addiction, as well as the mediating role of fear of missing out between the dark triad and smartphone addiction.Methods:A total of 408 college students were assessed using dirty dozen, fear of missing out scale, and mobile phone addiction index. SPSS 24.0 software was used for common method bias tests, descriptive statistical analysis, and correlation analysis. Mplus 8.3 software was employed to construct a structural equation model, and the Bootstrap method was used for mediation effect analysis.Results:The dark triad (36.14±9.06) was positively correlated with fear of missing out (22.55±6.60) and smartphone addiction (46.77±13.62) ( r=0.48, 0.45, both P<0.01). Fear of missing out was also positively correlated with smartphone addiction ( r=0.54, P<0.01). Fear of missing out played a partial mediating role in the relationship between the dark triad and smartphone addiction, with a total effect value of 0.495 and a mediating effect value of 0.217. Conclusion:Fear of missing out partially mediates the relationship between the dark triad and smartphone addiction. The dark triad not only directly predicts smartphone addiction but also indirectly influences smartphone addiction through fear of missing out.
