Objective: To analyze the epidemiological characteristics and influencing factors of severe fever with thrombocytopenia syndrome (SFTS) in Zhejiang Province from 2019 to 2023, so as to provide the reference for strengthening SFTS prevention and control. Methods: Data on laboratory-confirmed SFTS cases in Zhejiang Province from 2019 to 2023 were collected through the Infectious Disease Reporting Information System of Chinese Disease Prevention and Control Information System. Meteorological data, geographic environment and socioeconomic factors during the same period were collected from the fifth-generation European Centre for Medium-Range Weather Forecasts, Geospatial Data Cloud, and Zhejiang Statistical Yearbook, respectively. Descriptive epidemiological methods were used to analyze the epidemiological characteristics of SFTS from 2019 to 2023, and a Bayesian spatio-temporal model was constructed to analyze the influencing factors of SFTS incidence. Results: A total of 578 SFTS cases were reported in Zhejiang Province from 2019 to 2023, with an annual average incidence of 0.23/105. The peak period was from May to July, accounting for 52.60%. There were 309 males and 269 females, with a male-to-female ratio of 1.15∶1. The cases were mainly aged 50-<80 years, farmers, and in rural areas, accounting for 82.53%, 77.34%, and 75.43%, respectively. Taizhou City and Shaoxing City reported more SFTS cases, while Shaoxing City and Zhoushan City had higher annual average incidences of SFTS. The Bayesian spatio-temporal interaction model showed good goodness of fit. The results showed that mean temperature (RR=1.626, 95%CI: 1.111-2.378) and mean wind speed (RR=1.814, 95%CI: 1.321-2.492) were positively correlated with SFTS risk, while altitude (RR=0.432, 95%CI: 0.230-0.829) and population density (RR=0.443, 95%CI: 0.207-0.964) were negatively correlated with SFTS risk. Conclusions SFTS in Zhejiang Province peaks from May to July. Middle-aged and elderly people and farmers are high-risk populations. Taizhou City, Shaoxing City, and Zhoushan City are high-incidence areas. Mean temperature, mean wind speed, altitude, and population density can all affect the risk of SFTS incidence.

Childhood simple obesity has become a significant public health issue in China. Modern medicine primarily relies on lifestyle interventions and often suffers from poor long-term compliance， while pharmacological options are limited and associated with potential adverse effects. Traditional Chinese Medicine （TCM） has a long history in the prevention and management of this condition， demonstrating eight distinct advantages， including systematic theoretical foundation， diversified therapeutic approaches， definite therapeutic efficacy， high safety profile， good patient compliance， comprehensive intervention strategies， emphasis on prevention， and stepwise treatment protocols. Additionally， TCM is characterized by six distinctive features： the use of natural medicinal substances， non-invasive external therapies， integration of medicinal dietetics， simple exercise regimens， precise syndrome differentiation， and diverse dosage forms. By combining internal and external treatments， TCM facilitates individualized regimen adjustment and holistic regulation， demonstrating remarkable effects in improving obesity-related metabolic indicators， regulating constitutional imbalance， and promoting healthy behaviors. However， challenges remain， such as inconsistent operational standards， insufficient high-quality clinical evidence， and a gap between basic research and clinical application. Future efforts should focus on accelerating the standardization of TCM diagnosis and treatment， conducting multicenter randomized controlled trials， and fostering interdisciplinary integration， so as to enhance the scientific validity and international recognition of TCM in the prevention and treatment of childhood obesity.

Objective: To evaluate the implementation process of a school-family collaborative "online+offline" tobacco control intervention program in junior high school in Beijing and to explore the execution status, influencing factors and sustainability potential of the intervention, so as to provide evidence for optimizing youth tobacco control strategies. Methods: In November 2024, using the random number table method, four first year junior high school classes were selected from three schools each in Fengtai District, Tongzhou District, and Fangshan District of Beijing. One class served as the control group, while the other three classes were designated as intervention groups (one each for online intervention, offline intervention, and combined online offline intervention). The control group received only conventional education.The online intervention group was engaged in WeChat push interventions, including watching micro videos, viewing promotional materials, participating in online quizzes and mini games; the offline intervention group attended knowledge lectures, played peer games, and participated in offline knowledge competitions; the combined online offline intervention group integrated all the aforementioned online and offline intervention measures. The intervention period was from November 2024 to June 2025, spanning a total of 7 months. Based on the Practical, Robust Implementation and Sustainability Model(PRISM) framework, a qualitative research design was employed to conduct semi structured interviews with 48 participants (12 in each of the intervention groups and 12 organizational staff members) from the Centers for Disease Control and Prevention (CDC) in 3 districts and 3 sampled schools. The interview outlines were designed according to the intervention plan. Data was managed using Nvivo 12.0 software and analyzed following Colaizzi s seven step phenomenological analysis method. Theoretical saturation was assessed using a reserved subset of transcripts. Results: Four core themes were identified in the tobacco control intervention process. Overall fidelity of intervention implementation was largely consistent with the original plan, and students showed strong willingness and positive evaluations toward interactive formats such as knowledge contests and peer games, though occasional breakdowns in school-family communication and blurred boundaries between online and offline components were observed; the participants showed a polarized response in terms of satisfaction and participation, most students and parents recognized the significance of the activity, and some parents observed a reduction in smoking behavior; the implementation of internal tobacco control policies in the school was strict, and the atmosphere was favorable, but there was still room for improvement, such as the scarcity of community tobacco control activities and the difficulty in implementing smoke free units; implementation and sustainability infrastructure were preliminarily established, such as through homeroom teacher supervision and training student assistants to assisted in activities, while the sustainability support system required further refinement. Conclusion The school-family collaborative "online+offline" tobacco control intervention has demonstrated significant positive effects, but further optimization of activity design, enhancement of community reward mechanisms, and standardized training are required to improve the efficacy and sustainability of the intervention.

Diabetic retinopathy is a common blinding complication in diabetic patients. Compared with conventional fundus color photography, fundus fluorescein angiography can dynamically display retinal vessel permeability changes, offering unique advantages in detecting early small lesions such as microaneurysms. However, existing intelligent diagnostic research on diabetic retinopathy images primarily focuses on fundus color photography, with relatively insufficient research on complex lesion recognition in fluorescein angiography images. This study proposed an adaptive multi-label classification model (D-LAM) to improve the recognition accuracy of small lesions by constructing a category-adaptive mapping module, a label-specific decoding module, and an innovative loss function. Experimental results on a self-built dataset demonstrated that the model achieved a mean average precision of 96.27%, a category F1-score of 91.21%, and an overall F1-score of 94.58%, with particularly outstanding performance in recognizing small lesions such as microaneurysms (AP = 1.00), significantly outperforming existing methods. The research provides reliable technical support for clinical diagnosis of diabetic retinopathy based on fluorescein angiography.

Long noncoding RNA (lncRNA) is a type of RNA that is longer than 200 nucleotides and does not encode proteins. Atopic dermatitis (AD) is a common chronic inflammatory skin disease. Genetic susceptibility, damaged skin barrier and immune imbalance play important roles in its pathogenesis. Studies have shown that abnormal expression of lncRNA plays an important role in the development of many human diseases. In recent years, it has been found that various lncRNAs are abnormally expressed in AD patients and are involved in the development of AD. This paper reviews the research progress of lncRNAs in AD, aiming to provide more reference for the pathogenesis and treatment of AD.

Super-enhancers are highly transcriptionally active epigenetic regulatory regions enriched with multiple enhancers, playing a crucial role in regulating gene activity and cell specialization. These regions are closely associated with tissue characteristics and disease development. While current research on super enhancers predominantly focuses on cancer and development, studies related to immune diseases are still in their infancy. This paper systematically reviews the potential applications of super enhancers in immune diseases, the related research techniques and methods, and the progress in understanding their roles in disease development. The aim is to provide a reference for developing super enhancer-based therapeutic strategies and to offer more effective treatment options for immune diseases.

Objective:To investigate the correlation between frailty and immune markers in elderly patients diagnosed with heart failure with preserved ejection fraction(HFpEF).Methods:A total of 416 elderly patients with HFpEF, who were hospitalized in the Department of Geriatrics at Henan Provincial People's Hospital from March 2021 to December 2023, were selected as research subjects.The Fried frailty phenotype was employed to assess frailty.Fasting venous blood samples were collected to measure levels of CD4+ T lymphocytes, CD8+ T lymphocytes, the CD4+ /CD8+ ratio, and immunoglobulins A, M, and G. Spearman correlation analysis and multiple linear regression analysis were conducted to evaluate the relationship between frailty scores and immune markers.Results:Spearman correlation analysis revealed a significant association between frailty score and the CD4+ /CD8+ ratio( r=-0.659, P<0.001), immunoglobulin A( r=-0.454, P<0.001), immunoglobulin M( r=-0.522, P<0.001), and immunoglobulin G( r=-0.802, P<0.001).Furthermore, multiple linear regression analysis indicated that, after adjusting for confounding factors, frailty score served as a significant negative predictor of the CD4+ /CD8+ ratio( β=-0.562, P<0.001), immunoglobulin A( β=-0.366, P<0.001), immunoglobulin M( β=-0.445, P<0.001), and immunoglobulin G( β=-0.772, P<0.001).In comparison to the non-frail group, the frail group exhibited significantly lower values for the CD4+ /CD8+ ratio( β=-0.666, P<0.001)and levels of immunoglobulin A( β=-0.514, P<0.001), immunoglobulin M( β=-0.526, P<0.001), and immunoglobulin G( β=-0.814, P<0.001). Conclusions:In hospitalized elderly patients with heart failure with HFpEF, frailty serves as an independent risk factor for the reduction of the CD4+ /CD8+ ratio, as well as levels of immunoglobulin A, immunoglobulin M, and immunoglobulin G. Furthermore, the frailty score demonstrates a significant negative predictive value for these immunological markers.Therefore, it is essential to enhance our understanding of frailty and to prioritize its prevention and treatment, as this may help mitigate immune dysfunction and promote recovery in elderly patients.

Objective:To evaluate the effect of a health management model based on the Integrated Theory of Health Behavior Change (ITHBC) on body mass index (BMI), blood lipids, quality of life, and self-management ability in elderly community-dwelling patients with chronic coronary syndrome (CCS).Methods:This randomized controlled trial enrolled elderly CCS patients attending the general outpatient clinic at Fangzhuang Community Health Service Center of Fengtai District, Beijing, between March 2023 and May 2024. Participants were randomly assigned to either an intervention group or a control group. The control group received routine care, while the intervention group received ITHBC-based health management for 12 months. Primary endpoints included BMI, blood lipid profiles (total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C)), quality of life (assessed across 5 domains: disease perception, physical limitation, angina stability, angina frequency, and treatment satisfaction), and patient self-management ability (assessed across 7 domains: symptom management, harmful habit management, emergency management, disease knowledge management, daily life management, treatment adherence management, and emotional cognition management).Results:A total of 140 patients were enrolled, with the age of 71.0(67.0, 75.0) years; 85 (60.71%) were male. Seventy patients were assigned to each group. At the 12-month follow-up, levels of TC, TG, and LDL-C in the intervention group were significantly lower than those in the control group (all P<0.05). No statistically significant differences were observed in BMI or HDL-C levels between the two groups (all P>0.05). Regarding quality of life, the intervention group had a significantly lower score in the disease perception domain than the control group ( P=0.007). No significant intergroup differences were found in the scores for physical limitation, angina stability, angina frequency, or treatment satisfaction (all P>0.05). For self-management ability, the symptom management score was significantly higher in the intervention group than in the control group ( P=0.030). No significant differences were observed between the groups in the remaining self-management domains (all P>0.05). Conclusions:The ITHBC-based health management model can improve blood lipid management in elderly community-dwelling CCS patients, with superior effects compared to routine care, although it doesn′t significantly improve BMI. The model also shows potential to improve patients′ quality of life and self-management ability; however, its effects in these areas are not significantly superior to those of routine care.
