ObjectiveTo explore the effectiveness of health information dissemination and its influencing factors using the "Shanghai CDC" WeChat public account as a case study, providing references for public health institutions to optimize the use of official new media platforms for effective publicity. MethodsA total of 1 030 headline articles published on the "Shanghai CDC" WeChat public account between 2016 and 2019 were analyzed using content analysis and non-parametric tests to examine the impact of factors such as titles and content categories. ResultsFrom 2016 to 2019, the number of WeChat public account followers increased by 280 000, with the articles accumulating over 8.8 million views. The median (P₂₅, P₇₅) open rate of articles was 5.90% (3.69%, 10.31%), and the median (P₂₅, P₇₅) sharing and forwarding rate was 6.60% (4.25%, 9.17%). Factors such as the use of first- and second-person pronouns, degree adverbs, negative adverbs, explicit viewpoints, and title length all significantly affected the open rate of articles, with OR (95%CI) values of 0.175 (0.041‒0.756), 32.606 (2.350‒452.432), 4.079 (1.093‒15.230), 0.106 (0.028‒0.409), and 1.184 (1.063‒1.319),respectively (all P<0.05). In terms of content, statistical significant differences in dissemination effectiveness were observed across article categories and themes (P<0.05). In terms of article categories, articles related to news hotspots and service information had higher open rates of 9.58% and 14.00%, respectively. These two types of articles also obtained higher sharing and forwarding rates of 7.65% and 9.16%, respectively. In terms of article topics, compared with healthy life and health products, among the top four topics in terms of publication volume, the open rates of articles about infectious diseases and disease-causing biology and immunization programs were higher, accounting for 7.88% and 6.88%, respectively, with no significant difference in sharing and forwarding rates. ConclusionThe "Shanghai CDC" WeChat public account demonstrated good dissemination effectiveness. Enhancing article titles by increasing informational content and degree adverbs (e.g., "highly," "most," and "extremely") and negative adverbs (e.g., "no") can improve dissemination reach. Public health WeChat accounts should incorporate news hotspots or service information in their articles. While maintaining their strengths in disseminating knowledge on infectious diseases and immunization programs, they should also enhance public education in other professional fields within their scope of responsibility to improve the overall dissemination impact of health information.

ObjectiveTo describe the epidemiological characteristics and trend of pulmonary tuberculosis among the elderly in Shanghai from 2014 to 2023, to estimate the incidence between 2024‒2025, so as to provide references for optimizing the prevention and control strategies of pulmonary tuberculosis for elderly in Shanghai. MethodsData of pulmonary tuberculosis patients aged ≥60 years in Shanghai registered in the Tuberculosis Registration and Management System of Chinese Center for Disease Control and Prevention from 2014 to 2023 was derived to describe the demographic characteristics of the elderly patients with pulmonary tuberculosis, and to calculate the reported incidence rate and annual percentage change (APC) of pulmonary tuberculosis. The autoregressive integrated moving average (ARIMA) model was constructed using monthly reported incidence data from January 2014 to June 2023, and data from July to December in 2023 were used to validate the model and predict the reported incidence rate of pulmonary tuberculosis among elderly in 2024 and 2025. ResultsA total of 19 208 elderly pulmonary tuberculosis patients were registered and reported in Shanghai from 2014 to 2023, with an average annual reported incidence rate of 35.04/100 000. The reported incidence rate of pulmonary tuberculosis in elderly showed an overall decreasing trend, APC=-3.34% (t=-3.360,P=0.010). While, the proportion of elderly pulmonary tuberculosis patients showed a yearly increasing trend among the total registered and reported cases, APC=5.65% (t=10.820, P<0.001). The difference in the average annual reported incidence rate of pulmonary tuberculosis in elderly was statistically significant in different regions (χ²=31.762, P=0.007), with the central urban areas(33.23/100 000) being lower than that in suburban areas (36.46/100 000), and the annual decreasing rate was faster in central urban area, APC=-4.88% (t=-4.838, P<0.001) and -2.76% (t=-2.811, P=0.023), respectively. The incidence rate was significantly higher in males than that in females (χ²=514.395, P<0.001). Additionally, the difference in reported incidence rate was statistically significant among different age groups(χ²=119.751,P<0.001), among which patients aged ≥80 years had the highest average annual incidence rate (59.69/100 000), and those aged ≤60 years had the lowest average annual incidence rate (28.57/100 000). Compared with the non-residential permanent elderly population (47.68/100 000), the average annual incidence rate of pulmonary tuberculosis among the elderly with household registration in Shanghai was lower (33.82/100 000) (χ²=24.295, P<0.001). The ARIMA (0,0,1) (0,1,1) 12 model was used to predict the incidence rate of pulmonary tuberculosis among the elderly in Shanghai in 2024 and 2025, and which was predicted to be 37.41/100 000 and 35.92/100 000, respectively. ConclusionThe reported incidence rate of pulmonary tuberculosis among the elderly in Shanghai showed an overall yearly downward trend from 2014 to 2023, but its proportion in the total number of reported pulmonary tuberculosis cases increased year by year. Prevention and control efforts should still not be slackened and emphasis should be placed on male, suburban and non-residential permanent elderly populations.

Furthermore, improving the stability of quantum dots under physiological conditions is crucial for their effective use in biomedical applications. Advances in surface engineering and the development of novel encapsulation methods have shown promise in addressing these stability concerns. Industrial production of quantum dots also presents challenges, particularly in achieving consistent quality and scalability. Recent innovations in synthesis techniques and manufacturing processes are paving the way for large-scale production, which is essential for their widespread adoption in clinical settings. This article provides an in-depth analysis of the latest research progress in quantum dot applications, including drug delivery, bioimaging, biosensing, photodynamic therapy, and pathogen detection. It also discusses the multiple barriers hindering their clinical use and explores potential solutions to overcome these challenges. The review concludes with a forward-looking perspective on the future directions of quantum dot research, emphasizing the need for further studies on toxicity mitigation, stability enhancement, and scalable production. By addressing these critical issues, quantum dots can realize their full potential as transformative tools in disease diagnosis and treatment, ultimately improving patient outcomes and advancing biomedical science.

Traditional Chinese Medicine (TCM), as a treasure of the Chinese nation, plays a significant role in maintaining public health. In 2019, the Central Committee of the Communist Party of China and the State Council proposed for the first time the establishment of a TCM registration and evaluation evidence system that integrates TCM theory, "personal experience" and clinical trials (referred to as the "Three-in-One" System) to promote the inheritance and innovation of TCM. Subsequently, the National Medical Products Administration issued several guiding principles to advance the improvement and implementation of this system. Owing to the complexity of its implementation, there are still differing understandings within the TCM industry regarding the positioning of the "Three-in-One" Registration and Evaluation Evidence System, as well as the connotation and value orientation of the "personal experience." To address this, Academician WANG Qi, President of the TCM Association, China International Exchange and Promotion Association for Medical and Healthcare and TCM master, led a group of academicians, TCM masters, TCM pharmacology experts and clinical TCM experts to convene a "Seminar on Promoting the Implementation of the ′Three-in-One′ Registration and Evaluation Evidence System for Chinese Medicinals." Through extensive discussions, an expert consensus was formed, clarifying the different roles of the TCM theory, "personal experience" and clinical trials within the system. It was further emphasized that the "personal experience" is the core of this system, and its data should be derived from clinical practice scenarios. In the future, the improvement of this system will require collaborative efforts across multiple fields to promote the high-quality development of the Chinese medicinal industry.

Objective To observe the effect of esketamine on postoperative recovery in children after endoscopic adenoidectomy.Methods Sixty pediatric patients who underwent adenoidectomy with endoscope from Jan 2022 to Jan 2023 in Eye&ENT Hospital,Fudan University were enrolled.The pediatric patients were randomly divided into hydro-morphine group(n=30)and esketamine group(n=30).Anesthesia induction:lidocaine 1.5 mg/kg,propofol 2.5 mg/kg and remifentanil 4 μg/kg were injected intravenously,and then the endotracheal tube was used for airway management.Anesthesia maintenance:remifentanil infusion was at 0.2-0.5 μg·kg-1·min-1 and the end tidal concentration of sevoflurane was at 0.7-1.0 minimum alveolar concentration(MAC).At the end of surgery,either hydromorphone 0.01 mg/kg or esketamine 0.5 mg/kg were administered for postoperative pain control.Time to resume spontaneous breathing was recorded.Other parameters included respiratory rate per minute,duration of stay in the post-anesthesia care unit,hemodynamic profiles.The adverse events including agitation and desaturation were also of note.Results Children in esketamine group resumed spontaneous breathing faster(P=0.048),had faster respiratory rate when recovery of spontaneous breathing(P=0.001)and lower concentration of end tidal CO2(P=0.005).The findings suggested that esketamine did not impair respiratory function.Compared to hydro-morphine group,children in esketamine group had shorter stay in the post-anesthesia care unit with statistical difference(P=0.020).Esketamine had no effect on heart rate and blood pressure,so there were less adverse events.Conclusion Compared with 0.01 mg/kg hydro-morphine,0.5 mg/kg esketamine does not impair respiratory function and it facilitate fast recovery in children undergoing endoscopic adenoidectomy after general anesthesia.

Objective:To explore the current status of barriers to participation in phaseⅡcoronary artery bypass grafting (CABG) patients and the factors influencing them, and to provide new ideas for reducing barriers to participation in rehabilitation and improving the participation rate in cardiac rehabilitation.Methods:For this study, a cross-sectional survey research method was utilized. The study included 334 patients who underwent CABG and were admitted to the Second Hospital of Hebei Medical University between June 2022 and May 2023. These patients were selected using the convenience sampling method. A General Information Questionnaire, the Cardiac Rehabilitation Barriers Scale (CRBS-C/M), and a Questionnaire on the Knowledge of Information Related to Cardiac Rehabilitation were used to conduct the survey. Multiple linear regression was used to analyze the independent influencing factors on barriers to participation in phase Ⅱ cardiac rehabilitation in post-CABG patients.Results:Out of 334 patients, 248 were males and 86 were females with age (54.74 ± 7.61) years old. The total average score of CRBS-C/M in patients after CABG surgery was 3.20 ± 0.43, with the highest external logistic factors score of 3.42 ± 0.58. The knowledge status score of information related to cardiac rehabilitation was 42.11 ± 7.94. Multiple linear regression analysis revealed that the following factors independently influenced post-CABG patients′ barriers to participating in phaseⅡcardiac rehabilitation: marital status, whether or not they had completed phase I cardiac rehabilitation,number of other comorbidities, knowledge of cardiac rehabilitation information. All of these differences were statistically significant ( t values were -4.87-3.35, all P<0.05). Conclusions:The barriers to participation in phase Ⅱ cardiac rehabilitation in post-CABG patients are at an intermediate to high level, and healthcare professionals should emphasize the assessment of barrier factors in these patients, and target the development and implementation of phase Ⅱ cardiac rehabilitation in terms of the influencing factors.

BACKGROUND:In clinical practice,Cibotium barometz and Epimedium have shown significant efficacy in the treatment of rheumatoid arthritis,but the complex active ingredients contained in the two have an unclear mechanism of action at the molecular level for the treatment of rheumatoid arthritis. OBJECTIVE:Based on network pharmacology and molecular docking technology,to establish a collagen-induced arthritis model and to verify the potential targets and pathways of Cibotium barometz and Epimedium in the treatment of rheumatoid arthritis,providing reliable experimental evidence for the use of clinical formulas with Cibotium barometz and Epimedium as the main components. METHODS:Utilizing traditional Chinese medicine research platforms,traditional Chinese medicine encyclopedias,and databases of traditional Chinese medicine and chemical components from the Shanghai Institute of Organic,effective ingredients were retrieved and identified.3D molecular formulas were obtained from the PubChem platform and target predictions were made using PharmMapper and SwissTargetPrediction.Disease targets for rheumatoid arthritis were obtained from gene databases such as DrugBank,GeneCards,and OMIM.The intersections of targets and Cibotium barometz and Epimedium were plotted using VENNY 2.1 after calibration with the Uniport database.A protein-protein interaction network graph was constructed using the STRING platform.Gene Ontology function analysis and Kyoto Encyclopedia of Genes and Genomes enrichment analysis were performed using the Metascape platform for data visualization.A four-layered network model of traditional Chinese medicine,ingredients,targets,diseases,and pathways was constructed using Cytoscape 3.9.0.The main effective ingredients were docked with core targets using AutoDock-Vina software to explore the best binding targets.A type II collagen+adjuvant-induced arthritis rat model was established,and the effects of Cibotium barometz and Epimedium on relevant pathway targets and inflammatory cell factors were observed after 21 days of intervention. RESULTS AND CONCLUSION:A total of 28 active ingredients from Cibotium barometz and Epimedium were selected,yielding 288 intersection targets for rheumatoid arthritis.The main ingredients included isobavachalcone,cibotium,and epimedium.The main targets included protein kinase 1 for serine/threonine(AKT1),tumor necrosis factor,and vascular endothelial growth factor A.Gene ontology analysis yielded 2 232 biological processes,mainly related to serine protein phosphorylation,positive regulation of serine/threonine protein kinase,and reactive oxygen metabolism.Kyoto Encyclopedia of Genes and Genomes enrichment analysis yielded 202 pathways,mainly involving the PI3K/AKT signaling pathway and epidermal growth factor receptor signaling pathway,which may exert therapeutic effects by regulating synovial cell apoptosis and proliferation and suppressing inflammatory factors.Molecular docking results showed the strongest binding activity and stable structure of Cibotium barometz and Epimedium with AKT1 and estrogen receptor transcription factor 1,which was closely related to apoptosis and proliferation and inflammatory signaling pathways such as PI3K/AKT.Cibotium barometz and Epimedium reduced the expression of interleukin-1β,interleukin-6,and tumor necrosis factor-α in the serum of collagen-induced arthritis rat models.Cibotium barometz and Epimedium reduced the expression of p-PI3K,p-AKT,and p-FOXO1 in the synovium of collagen-induced arthritis rat models.The results indicate that the combination of Cibotium barometz and Epimedium may exert therapeutic effects by inhibiting the proliferation of synovial cells and suppressing the expression of inflammatory factors via the PI3K/AKT/FOXO1 signaling pathway.This may be closely related to the occurrence of inflammation and bone destruction in rheumatoid arthritis,and provides a reference for the rational use and development of new drugs in clinical practice.

Objective:To investigate the effect of five-element music therapy combined with meridian-based acupoint massage timed according to qi circulationon on negative emotions and sleep quality in older adults with chronic heart failure. Methods:A total of 112 older adult patients with chronic heart failure who received treatment at The Affiliated Hospital of Hangzhou Normal University between January 2022 and June 2023 were included in this study. They were randomly divided into a control group ( n = 56) and a study group ( n = 56) using the random number table method. Based on conventional treatment, the control group received five-element music therapy, while the intervention group underwent a combination of five-element music therapy and meridian-based acupoint massage timed according to qi circulation. Before and after the intervention, a comparison was made between the two groups in terms of the scores of the Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), Pittsburgh Sleep Quality Index (PSQI), and various dimensions of the Minnesota Living with Heart Failure Questionnaire (MLHFQ). Additionally, the sleep outcome and patient satisfaction were also compared between the two groups.

In contrast, the control group had scores of (15.93 ± 3.35) points and (16.50 ± 4.32) points, respectively. After intervention, the scores of the HAMA and HAMD scales in both the study and control groups demonstrated a significant reduction in comparison with their respective pre-intervention scores [study group: (20.13 ± 5.18) points, (23.95 ± 8.97) points, control group: (19.36 ± 5.45) points, (23.79 ± 7.61) points, t = 15.35, 10.24, 5.65, 8.93, all P < 0.001). After intervention, the scores of the HAMA and HAMD scales in the study group were significantly lower than those in the control group ( t = -8.34, -5.49, both P < 0.001). After intervention, the scores of the PSQI in the study and control groups were (7.05 ± 0.96) points and (9.91 ± 1.28) points, respectively. After intervention, the scores of PSQI in both the study and control groups demonstrated a significant reduction compared with their respective pre-intervention scores [study group: (12.98 ± 2.21) points, control group: (12.50 ± 2.48) points, t = 24.68, 9.79, both P < 0.05]. After intervention, the score of the PSQI in the study group was significantly lower than that in the control group ( t = 13.34, P < 0.05). Based on the scores across various dimensions of the MLHFQ, it was observed that after intervention, the scores of emotional, physical, and other domains in both the study and control groups [study group: (9.36 ± 2.29) points, (16.95 ± 3.80) points, (18.50 ± 2.33) points; control group: (12.93 ± 2.00) points, (19.98 ± 3.98) points, (20.04 ± 2.24) points] decreased significantly compared with their pre-intervention scores [study group: (15.57 ± 1.55) points, (26.23 ± 4.63) points, (21.18 ± 2.50) points, control group: (16.09 ± 1.87) points, (25.32 ± 4.40) points, (21.57 ± 2.69) points, t = 21.66, 18.55, 8.44, 11.29, 11.73, 4.61, all P < 0.001]. After intervention, the scores of emotional, physical, and other domains in the study group were significantly lower than those in the control group ( t = -8.79, -4.13, -3.56, all P < 0.05). Patient satisfaction in the study group was superior to that that in the control group [98.21% (55/56) vs. 87.50% (49/56), χ2 = -3.09, P < 0.05]. Total effective rate of intervention on sleep in the study group was significantly higher than that in the control group [92.86% (52/56) vs. 78.57% (44/56), χ2 = -2.09, P < 0.05]. Conclusion:Five-element music therapy combined with meridian-based acupoint massage timed according to qi circulationon in the treatment of chronic heart failure in older adults can effectively alleviate negative emotions, improve the quality of life and sleep, and increase patient satisfaction with nursing care.
