Osteoporosis is a common bone disease， whose incidence is still on the rise， posing great challenges to patients and society. This review mainly studies the pathogenesis of osteoporosis from the aspects of oxidative stress， inflammatory response， and glucolipotoxicity-induced injury and clarifies the efficacy and mechanism of some active ingredients of traditional Chinese medicine against osteoporosis through the integration of in vitro and in vivo experiments. The experimental results suggest that some active ingredients can improve bone resorption markers and maintain bone homeostasis by modulating inflammation， oxidative stress， etc. These active ingredients regulate osteoporosis through the receptor activator of nuclear transcription factor-κB （NF-κB） ligand （RANKL） pathway， osteoprotegerin （OPG） pathway， Wnt/β-catenin pathway， NF-κB pathway， mitogen-activated protein kinase （MAPK） pathway， adenosine monophosphate （AMP）-activated protein kinase （AMPK）/mammalian target of rapamycin （mTOR） pathway， and oxidative stress pathway. This review provides ideas for the progress of the prevention and treatment of osteoporosis with the active ingredients of traditional Chinese medicine， aiming to provide new potential lead compounds and reference for the development of innovative drugs and clinical therapy for the treatment of osteoporosis.

Implementation Science is an interdisciplinary field dedicated to systematically studying how to effectively translate evidence-based research findings into practical application and implementation. In the health-related context, it focuses on enhancing the efficiency and quality of healthcare services, thereby facilitating the transition from scientific evidence to real-world practice. This article elaborates on Theories, Models, and Frameworks (TMF) within health-related Implementation Science, clarifying their basic concepts and classifications, and discussing their roles in guiding implementation processes. Furthermore, it reviews and prospects current research from three aspects: the constituent elements of TMF, their practical applications, and future directions. Five representative frameworks are emphasized, including the Consolidated Framework for Implementation Research (CFIR), the Practical Robust Implementation and Sustainability Model (PRISM), the Exploration, Preparation, Implementation, Sustainment (EPIS)framework, the Behavior Change Wheel (BCW), and the Normalization Process Theory (NPT). Additionally, resources such as the Dissemination & Implementation Models Webtool and the T-CaST tool are introduced to assist researchers in selecting appropriate TMFs based on project-specific needs.

Cardiomyopathy is a group of heterogeneous myocardial diseases with a variety of specific phenotypes that can lead to cardiovascular death or progressive heart failure in severe cases.Because of the severity and complexity of these diseases,the search for new regulatory mechanisms to prevent and treat cardiomyopathy is particularly urgent.Iron death is a form of programmed cell death that differs from other forms of iron dependence and is characterized by the accumulation of iron-dependent lipid peroxides.Studies have shown that iron death can be involved in the occurrence and progression of cardiomyopathy through different signaling pathways.Therefore,targeted regulation of iron death is a new strategy to prevent cardiomyopathy.In this paper,the mechanism of iron death and its important role in cardiomyopathy were reviewed to find the potential relationship between iron death and cardiomyopathy and provide more ideas for the treatment of various cardiomyopathies in the future.

Objective To investigate the clinical characteristics,treatment and prognosis of tuberculosis in patients with autoimmune diseases after tumor necrosis factor-αinhibitors.Methods Clinical data of 33 patients with TB after biologics(tumor necrosis factor-α inhibitors)treated in Guangzhou Chest Hospital from January 2019 to March 2023 were collected,including 25 males and 8 females,with a median age of 32 years.The clinical symptoms,laboratory results,imaging and tracheoscopic features,pathological features,treatment and outcome were analyzed retrospectively.Results The common clinical manifestations were cough(26/33),sputum(23/33)and fever(17/33).The most common cases were pulmonary tuberculosis(32/33),bronchial tuberculosis(15/33),mediastinum and hilar lymph node tuberculosis(11/33).Bilateral lung spread of tuberculosis(21/33),intrapulmonary spread of tuberculosis(bronchus,mediastinal hilar lymph nodes,pleura)(19/33),extrapulmonary tuberculosis(18/33),pulmonary tuberculosis with intrapulmonary or extrapulmonary tuberculosis(26/33).Blood CD4+T lymphocyte test was normal(23/33),and blood IGRA test was positive(27/33).Pulmonary imaging miliary nodules(8/33).The histopathology of the lymph nodes showed atypical granulomatous nodules.The duration of anti-tuberculosis treatment is 8-32 months.1 case of death.Conclusion Patients with autoimmune diseases complicated with tuberculosis after the application of tumor necrosis fact-α inhibitor are more likely to have double lung lesions,which are easy to spread to lung tissues and multiple organs of the body,and have decreased immune function.Most of them need to extend the treatment course,and the prognosis is generally good after comprehensive treatment.

Objective To analyze the role of the key items list in the quality control of running medical records by com-paring the improvements of the quality of medical records,and to explore more effective ways of quality management of medical records.Methods Based on the goal setting theory and influencing factors of goal incentive utility,a list of key items for medi-cal record quality management was formulated,which was implemented in a children's hospital in Tianjin since April 2023.A to-tal of 4 823 operating medical records were collected from June 2022 to September 2023,and the defect rates of quality control items were compared by using statistical methods.Results After the implementation of the key items list,the average score of operating medical records was improved,and the defect rate decreased from 13.63％to 7.94％.Moreover,the defect rates of admission records,first-trip records,senior physician rounds records,consultation records,and surgical records decreased from 4.25％,3.07％,8.26％,and 10.56％to 1.61％,1.56％,4.41％,and 5.06％.Conclusion The implementation of key i-tems list management can effectively improve the quality of running medical records,reduce the defects of medical records,and improve the effects of medical record management.

Radiotherapy can cause functional and morphological changes in the brain tissues of patients with primary or metastatic malignant brain tumors, leading to radiation-induced brain injury. However, the pathogenesis of radiation-induced brain injury has not yet been unanimously determined, and its research advances and treatment protocols are yet to be elucidated and improved. In this study, we explore the pathogenesis of radiation-induced brain injury from the perspective of vascular injury, inflammatory reactions, neuronal dysfunction, glial cell injury, and gut microbiota and reviewed the advances in research on its treatment and prevention. The purpose is to provide a reference and theoretical basis for the research and clinical diagnosis and treatment of radiation-induced brain injury.

Objective:To retrospectively analyze the anesthetic management characteristics of children undergoing resection of pheochromocytoma and paraganglioma (PPGL).Methods:The clinical data from patients undergoing resection of PPGL and confirmed histologically from January 1, 2010 to June 30, 2023 were retrospectively collected. The baseline characteristics, intraoperative conditions and postoperative complications were recorded.Results:The clinical data from 47 pediatric patients were analyzed. The overall incidence of hemodynamic instability events was 68% (32 cases). Lowering preoperative blood pressure to normal levels and the maximum diameter of tumor≥6 cm was helpful in reducing the incidence of the intraoperative hemodynamic instability events ( P<0.05). Postoperative hypotension developed in 7 cases, acute left heart failure in 1 case, arrhythmia in 1 case, adrenocortical insufficiency in 4 cases, and pulmonary infection in 13 cases. Conclusions:Thorough preoperative preparation, evidence-based anesthetic management, and meticulous postoperative vital sign monitoring can increase the perioperative safety for children undergoing resection of PPGL, thereby reducing the incidence of complications.

Objective: To explore the current status and associated factors of bullying behavior among middle school students in Shanghai, so as to provide a reference basis for carrying out bullying intervention work. Methods: From May to June 2021, a stratified cluster sampling method was used to select 19 000 middle school students from 63 schools in 16 districts of Shanghai, and the Shanghai Youth Health Risk Behavior Survey Questionnaire was used to conduct an anonymous questionnaire survey of enrolled students. Chi square test and binary Logistic regression analysis were employed to investigate the associated factors of bullying among middle school students. Results: The prevalence of bullying behaviors in Shanghai was 15.5%, with males and junior high school students exhibiting the higher reporting rate(19.5%,17.2%). And malicious teasing or name calling had the highest reported rate at 9.4%. The results of binary Logistic regression analysis showed that fighting ( OR =5.02), attempting to smoke ( OR =3.22), having a feeling of sadness and hopelessness ( OR =2.50) and getting drunk( OR =1.72) were positively associated with bullying behavior among middle school students. Fighting ( OR =3.83-8.97), attempting to smoke ( OR =2.92-5.52), having a feeling of sadness and hopelessness ( OR =2.40-4.34), and getting drunk ( OR =1.66-2.34) were positively correlated with 6 forms of bullying (malicious teasing or name calling, intentionally damaging someone else s belongings, deliberately excluding someone from activities or isolating someone, threatening or intimidating others, hitting, kicking, or pushing someone, and verbally harassing or attacking someone online) ( P <0.05). Conclusions Bullying behavior of middle school students in Shanghai primarily presents as verbal harassment. In the future, greater attention should be directed towards bullies, and it should recognize potential hazards promptly and implement precise intervention measures.

Objective: To understand the relationship between stress and Internet addiction among middle school students in Shanghai, so as to provide a scientific basis for promoting students mental health and preventing Internet addiction. Methods: From May to June 2021, a stratified random cluster sampling method was used to select 6 123 middle and high school students in Shanghai for health risk behavior monitoring. Daily Stressors Evaluation Scale for Urban Secondary School Students was used to evaluate students' stress, and the Internet Addiction Test compiled by Young was used to evaluate students Internet addiction. The correlation between student stress and Internet addiction was analyzed by Kruskal-Wallis H test , Chi square test and multiple Logistic regression. Results: Total stress score of middle school students in Shanghai was 24 (12, 39), academic stress score was 8 (5, 13), physical and psychological stress score was 6 (2, 10), interpersonal stress score was 5 (1, 9), and family stress score was 4 (1, 8). The detection rate of Internet addiction was 4.7%. Multivariate Logistic regression analysis showed that the risk of Internet addiction among middle school students with high levels of stress was 8.05 times(95% CI =4.59-14.12) that of students with low levels of stress( P <0.05). The risk of Internet addiction among middle school students with high levels of academic stress, physical and psychological stress, interpersonal stress and family stress was 5.98(95% CI =3.69-9.70), 6.92(95% CI =4.03-11.88), 4.85(95% CI =3.11-7.55), and 4.18(95% CI =2.73-6.40) times that of students with low levels of stress, respectively( P <0.05). Conclusion The academic stress, physical and psychological stress, interpersonal stress, and family stress among middle school students can all lead to an increased risk of Internet addiction.
