Objective: To investigate the epidemiological characteristics and spatial-temporal clustering of varicella in Changchun City from 2020 to 2024, so as to provide the evidence for formulating local varicella prevention and control measures. Methods: The individual case data of varicella were collected through the Surveillance and Reporting Management System of the Chinese Disease Prevention and Control Information System in Changchun City from 2020 to 2024. Descriptive epidemiological methods were used to analyze the population ,regional, and temporal distribution. Spatial autocorrelation and spatio-temporal scanning analyses were used to identify the spatial-temporal clustering characteristics. Results: A total of 8 850 varicella cases were reported in Changchun City from 2020 to 2024, with an average annual incidence of 19.64/105. There were 4 929 male cases and 3 921 female cases, with a male-to-female ratio of 1.26∶1. The age was mainly 0-<20 years (6 649 cases, 75.13%), and students were the predominant occupation (6 036 cases, 68.20%). The top three counties (cities, districts) with the highest number of cases were Chaoyang District (1 944 cases), Gongzhuling City (1 054 cases) and Nanguan District (987 cases), accounting for 45.03%. The peak incidence periods were from April to June and from October to December, with 2 166 and 4 226 cases, accounting for 24.47% and 47.75%, respectively. Spatial autocorrelation analysis showed that spatial clustering existed from 2020 to 2024. The high-high clustering areas were mainly some townships (streets) in Chaoyang District, Nanguan District, Changchun New District and Jingyue District. Spatio-temporal scanning analysis identified 6 high-risk clustering areas. The class Ⅰ clustering area was Nanhu Street in Chaoyang District, with the clustering period from September 2020 to February 2022. Conclusions Varicella cases in Changchun City were mainly males and students aged 0-<20 years from 2020 to 2024. The peak incidence was mainly in winter. Chaoyang District was a high-risk area, with obvious spatial-temporal clustering.

Objective: There were associations between emotional abuse and neglect (EAN) and depression, but few studies had tested potential mechanisms underlying these relationships. We aimed to provide insights on how (the mediation role of neuroticism), and under what conditions (the moderator role of psychological resilience), led to a higher level of depression. Methods: This study was a cross-sectional study that used a random cluster sampling method. We randomly selected 3,993 participants from four junior middle schools in northern city of China. Participants were asked to complete four self-reported questionnaires, including the Childhood Trauma Questionnaire, Children Depression Inventory-Short Form, Chinese Big Five Personality Inventory Brief Version, and Chinese Resilience Scale. Results: The results showed that neuroticism mediated the associations between EAN and depression. In addition, the mediating effect of neuroticism was moderated by psychological resilience (p<0.05). Conclusion EAN and neuroticism could have an adverse impact on depression, and psychological resilience could alleviate these negative effects as a moderator. Our model suggested psychological resilience could be a particularly effective intervention point for victims of EAN.

OBJECTIVES: To investigate the effects of formulated granules of Tianma Gouteng Yin (TGY) on motor deficits in a mouse model of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced subacute Parkinson's disease (PD) and explore the possible molecular mechanisms. METHODS: Ninety C57BL/6 mice were randomized equally into 6 groups, including a control group, a PD model group, a NEC-1 (6.5 mg/kg) treatment group, two TGY treatment groups at 5 and 2.5 g/kg, and a Madopar (76 mg/kg) treatment (positive control) group. Mouse models of PD were established by intraperitoneal injection of MPTP (30 mg/kg) for 5 consecutive days with the corresponding treatments for 15 days. The mice were randomly selected for motor function tests. Western blotting was used to detect the changes in expressions of TH, α-syn, RIPK1, RIPK3 and MLKL in the striatum of the mice. Network pharmacology analysis and molecular docking studies were performed to explore TGY-mediated regulation of the necroptosis pathway for PD treatment. RESULTS: Compared with those in the control group, the PD model mice exhibited obvious motor deficits with significantly increased α-syn protein expression and lowered TH protein expression in the striatum. Treatment with NEC-1 obviously improved motor deficits, inhibited the necroptosis pathway, and alleviated the changes in TH and α‑syn proteins in PD mice. Network pharmacology and molecular docking analyses suggested that the therapeutic effect of TGY in PD was associated with the modulation of RIPK1, a key protein in the necroptosis pathway. In PD mouse models, TGY treatment at the two doses significantly improved motor deficits of the mice, increased TH expression, and decreased the expressions of α-syn and necroptosis-related proteins in the striatum. CONCLUSIONS TGY can effectively inhibit the necroptosis pathway, increase TH expression and decrease α-syn expression in the striatum to improve motor deficits in PD mice.

Bio-mineralization has emerged as a promising strategy to enhance vaccine immunogenicity. This study optimized the calcium phosphate (CaP) mineralization process of foot-and-mouth disease virus-like particles (FMD VLPs) to achieve high mineralization efficiency and scalability. Key parameters, including concentrations of Ca²⁺, HPO₄^2-, NaCl, and VLPs, as well as stirring speed, were systematically optimized. Stability of the scaled-up reaction system and immunogenicity of the mineralized vaccine were evaluated. Optimal conditions [25.50 mmol/L Ca(NO₃)₂, 15 mmol/L Na₂HPO₄, 300 mmol/L NaCl, 0.75 mg/mL VLPs, and 1 500 r/min] yielded CaP-mineralized VLPs (VLPs-CaP) with high mineralization efficiency, uniform morphology, and a favorable particle size. Scaling up the reaction by 25 folds maintained consistent mineralization efficiency and particle characteristics. Immunization in mice demonstrated that VLPs-CaP induced higher titers of specific antibodies and neutralizing antibodies than unmineralized VLPs (P < 0.05). Higher IgG2a/IgG1 ratio and enhanced IFN-γ secretion (P < 0.05) further indicated robust cellular immune responses. We establish a stable and scalable protocol for VLPs-CaP, providing a theoretical and technical foundation for developing high-efficacy VLPs-CaP vaccines.

Objective:To explore the trajectories of kinesiophobia in initial hemodialysis patients and their influencing factors.Methods:A convenience sampling method was used to recruit patients undergoing their first hemodialysis treatment at Hemodialysis Center, the Affiliated Huai'an No.1 People's Hospital of Nanjing Medical University from June to December 2023. Baseline data were collected using a general information questionnaire, the Tampa Scale for Kinesiophobia (TSK), the Dialysis Patient Symptom Burden Index (DFSSBI), the Fear of Progression Questionnaire-Short Form (FoP-Q-SF), the Multidimensional Fatigue Inventory (MFI-20), and the Pittsburgh Sleep Quality Index (PSQI). The TSK was used to measure kinesiophobia levels at 1, 3, and 6 months post-dialysis. Data were analyzed using a latent class growth mixture model, univariate analysis, and multinomial Logistic regression.Results:A total of 251 patients were surveyed, and 239 completed follow-ups. Three latent classes of kinesiophobia trajectories were identified: persistently high kinesiophobia group (32.22%, 77/239), moderate kinesiophobia-declining group (28.45%, 68/239), and persistently low kinesiophobia group (39.33%, 94/239). Multinomial Logistic regression analysis indicated that age, marital status, presence of sleep disorders, history of falls in the past year, symptom burden, fear of disease progression, and fatigue significantly influenced kinesiophobia trajectory classes ( P<0.05) . Conclusions:Kinesiophobia in initial hemodialysis patients exhibits distinct trajectories. Healthcare professionals should implement targeted interventions based on the influencing factors of kinesiophobia trajectory development.
