Polycystic ovary syndrome （PCOS） is a common reproductive-endocrine and metabolic disorder in women of reproductive age， and chronic low-grade inflammation is closely associated with its pathogenesis. Studies have confirmed that the abnormal activation of NOD-like receptor protein 3 （NLRP3） inflammasome， a key complex of the innate immune system， not only mediates the formation of local ovarian inflammatory microenvironment， but also deeply participates in the processes of hyperandrogenemia， follicular developmental arrest and systemic insulin resistance in PCOS patients. A variety of single-herb medicines and their active ingredients （such as ginsenosides， evening primrose oil， safflower yellow， etc.）， as well as compound prescriptions including Jianpi yishen huazhuo formula， Bushen huatan formula and Bushen huoluo decoction， can effectively alleviate chronic low-grade inflammation related to PCOS， ameliorate insulin resistance， hyperandrogenemia and abnormal ovarian microenvironment by inhibiting the abnormal activation of NLRP3 inflammasome， and ultimately promote follicular development and the recovery of ovulatory function. Nevertheless， the methodological quality of existing studies is generally low， and clinical translation is still restricted by the heterogeneity of experimental models， unclear pharmacodynamic material basis and lack of high-quality evidence-based data. Multi-omics technologies should be adopted in future research to further analyze the compatibility rules of Chinese herbal compound prescriptions， and stratified studies should be carried out according to different phenotypes of PCOS.

Objective: To examine the effects of combined aerobic and resistance exercise on health related physical fitness (HPF) and depressive symptoms among senior high school freshmen, and to examine whether HPF mediates the relationship between exercise intervention and depressive symptoms, so as to provide a scientific basis for the coordinated promotion of mental health and physical fitness in schools. Methods: In March 2022, 190 senior high school freshmen from a secondary school of Suzhou in Anhui Province were selected by the random cluster sampling method and randomly assigned to an intervention group ( n = 99) and a control group ( n =91). The control group maintained routine activities, while the intervention group underwent a 10 week combined aerobic and resistance exercise program, three sessions per week, 40 minutes per session. Height, weight, standing long jump, sit ups, 20 m shuttle run, and sit and reach were measured before and after the intervention. Depressive symptoms were assessed using the Center for Epidemiological Studies Depression Scale (CES-D). Analysis of covariance (ANCOVA), Mann-Whitney U test, and Wilcoxon test were employed to compare outcomes before and after the intervention, and mediation analysis was conducted. Results: After controlling for pre test scores, ANCOVA results showed that compared with the control group, the intervention group demonstrated the following post intervention changes: a lower body mass index of 0.1 kg/m 2 among girls; higher standing long jump (13.2 cm for boys, 7.4 cm for girls), higher sit ups (5.5 reps for boys, 3.7 reps for girls), higher 20 m shuttle run (7.4 times for boys, 5.1 times for girls), and higher sit and reach (3.2 cm for boys, 0.4 cm for girls) ( F =17.88-84.44); and lower CES-D scores (5.5 for boys, 4.0 for girls) ( Z =-2.51, -2.06) (all P <0.05). The indirect effect of HPF in the relationship between combined aerobic and resistance exercise and depressive symptoms was -2.11, supporting a partial mediation effect ( P < 0.01 ). Conclusions Combined aerobic and resistance exercise improves HPF and alleviates depressive symptoms to varying degrees among senior high school freshmen. HPF served as a partial mediator through which exercise intervention reduces depressive symptoms.

ObjectiveTo develop a systematic case management model based on the International Classification of Functioning, Disability and Health (ICF) Vocational Rehabilitation Core Set (VR-CS) and explore its application pathways and efficacy in vocational rehabilitation. The 13 core categories of VR-CS are applied in vocational rehabilitation case management practices, utilizing comprehensive functional assessments to design and implement structured and individualized case management plans. This, in turn, seeks to enhance individuals' vocational independence, social participation and overall quality of life. MethodsThis study adopted a combined approach of theoretical research and empirical case analysis. Based on the 13 core categories of VR-CS, a comprehensive vocational assessment was conducted across three dimensions: body function and structure, activities and participation, and environmental factors. The study theoretically analyzed how to develop and implement holistic and individualized vocational rehabilitation plans, along with dynamic monitoring processes. Three types of typical vocational rehabilitation cases were examined, including individuals with major depressive disorder, high-functioning autism and mild cognitive impairment, to illustrate the evidence and effectiveness of VR-CS-based case management. ResultsThe VR-CS-based case management method, grounded in the ICF bio-psycho-social model, constructed an integrated and individualized case management system. This system combined the assessment and analysis of vocational rehabilitation needs, goal setting and planning, multidisciplinary team intervention, individualized interventions, process monitoring and dynamic adjustments, return-to-work activities, and long-term follow-up services.The case management model developed through VR-CS demonstrated significant and systematic efficacy in promoting vocational independence and social participation. This study provided a detailed analysis of the primary methods and steps involved in designing and implementing case management and elaborates on the practical applications of this model from the three representative cases. At the body function and structure level, case management included the evaluation of energy and drive functions (b130), high-level cognitive training (b164), and the enhancement of exercise tolerance (b455). Case management focused on accurately setting short- and long-term goals around functional limitations and needs. Dynamic monitoring during interventions ensured timely adjustments to intervention measures. This process improved physical endurance and cognitive function, enhanced sustained work capacity in complex vocational environments. At the activities and participation level, the focus was on skill acquisition (d155), stress management and psychological adjustment (d240), and the cultivation of complex interpersonal communication abilities (d720). Individuals engaged in regular professional skills training, role-playing and simulated work scenarios to progressively enhance vocational adaptability and social interaction skills. Through this process, individuals acquired practical skills, gradually boosting self-efficacy and vocational confidence, thereby facilitating the reshaping of their social roles. At the environmental and personal factors level, case management pathways involved active participation from immediate family (e310), positive shifts in societal attitudes (e460), and the effective utilization of health and employment policy resources (e580, e590). By integrating social and community resources comprehensively, the program created a more inclusive and supportive rehabilitation environment. By designing and implementing systematic case management programs, individuals showed significant improvements in psychological well-being, vocational adaptability and social interaction skills. The majority of cases achieved stable employment or continued participation in social activities following the intervention. ConclusionVR-CS provides a systematic, multidimensional and person-centered case management framework. This framework applies the bio-psycho-social model, analyzing individuals' primary functional impairments and vocational rehabilitation needs from the perspectives of body functions, psychological states and environmental factors. On this basis, a comprehensive, targeted and holistic case management plan is developed and implemented. The VR-CS-based case management approach not only enhances vocational capabilities but also improves overall quality of life and social adaptability.

Objective To explore the risk factors for the occurrence of hypertension in middle-aged and elderly residents in China using the Cox regression analysis model and decision tree model, and compare the differences between the two methods. Methods The 2011-2015 China Health and Retirement Longitudinal Study data were used. The study investigated the risk factors for hypertension using both a multivariate Cox regression model and a decision tree model. Results The results showed that the incidence rate of hypertension between 2011-2015 was 22.79%. Both the Cox regression model and decision tree model identified age, education level, body mass index, and diabetes as risk factors for hypertension. The Cox regression model also identified drinking status as a risk factor, while the decision tree model identified gender and marital status as additional risk factors. The area under the curve (AUC) suggested that the Cox regression model and decision tree model had comparable ability to predict hypertension. Conclusions The risk factors for hypertension include gender, age, education level, marital status, alcohol consumption, body mass index, and history of diabetes. The effectiveness of the hypertension prediction model established based on Cox regression model and decision tree model results is not different.

ObjectiveTo reconstruct the vocational rehabilitation service process based on the framework and tools of the International Classification of Functioning, Disability and Health (ICF), to establish a systematic and standardized vocational rehabilitation service system to achieve the integrated development of vocational rehabilitation and other rehabilitation services, and to improve the overall rehabilitation effect and quality of life of people with disabilities. By establishing a systematic and standardized vocational rehabilitation service system, it provides function-oriented, holistic rehabilitation services for the whole person. MethodsThis study adopted the ICF framework and tools to conduct a systematic analysis of the vocational rehabilitation process. Based on this, according to the functional characteristics and systematic application of ICF-based tools, a vocational rehabilitation process was constructed, including functional assessment and rehabilitation goal setting, rehabilitation plan formulation, implementation of multidisciplinary intervention, outcome evaluation and quality of life assessment, and long-term follow-up and support. ResultsBased on the ICF framework and the application of ICF tools, according to the characteristics and nature of work of vocational rehabilitation institutions for persons with disabilities, a five-step vocational rehabilitation process was constructed. The main activity content of each process was defined in detail, and the ICF tools used and the methods of application were determined. The reengineering of the vocational rehabilitation process significantly improved the efficiency and quality of multidisciplinary comprehensive rehabilitation. The ICF framework and tools were the conceptual framework and platform for communication and collaboration among multidisciplinary teams. According to different vocational rehabilitation processes, the normative application of ICF-based tools ensured the development and implementation of scientific and effective rehabilitation intervention programs. The use of ICF-based tools also integrated vocational rehabilitation with other rehabilitation services, and achieved synergy among different rehabilitation services and different rehabilitation institutions. ConclusionThis study reengineered the vocational rehabilitation process based on the ICF framework, and constructed an ICF-based vocational rehabilitation process including the following five key processes, namely functional assessment and rehabilitation goal setting, formulating personalized and holistic rehabilitation plan, multidisciplinary team implementing comprehensive intervention strategies, evaluations of outcome and quality of life, and long-term follow-up and support services. Using the ICF framework and tools, the vocational rehabilitation service process of rehabilitation institutions has been reengineered, and an integrated rehabilitation service system has been constructed to provide a function-oriented comprehensive rehabilitation model, so that people with disabilities could receive whole-person rehabilitation services throughout their life cycle. Establishing a common language and tools based on ICF can effectively improve communication and collaboration among professionals, and also provide standardized tools for cross-institutional service integration, which is conducive to achieve smooth collaboration and information sharing among different rehabilitation institutions, ensuring the smooth transition of people with disabilities between different rehabilitation stages and institutions, and ensuring the coherence and integrity of the rehabilitation process.

Objective:To explore the current situation of evidence-based nursing competence of oncology nurse specialists and its influencing factors, so as to provide reference for conducting oncology nurse specialist training courses.Methods:From October 12th to 20th, 2022, convenience sampling was used to select oncology nurse specialists from Beijing as the research subject. The survey was conducted using the General Information Questionnaire, Oncology Nurse Specialists ' Cognition and Training Questionnaire on Evidence-based Nursing, Evidence-based Nursing Competence Scale, Nurse Innovative Behavior Scale, short versions of the Evidence-based Practice (EBP) Beliefs Scale, the EBP Implementation Scale, and the EBP Organizational Culture and Readiness Scale. Single factor analysis and multiple linear regression were used to explore the influencing factors of evidence-based nursing competence of oncology nurse specialists. Results:A total of 183 oncology nurse specialists were included. The scores of evidence-based nursing competence and innovative behavior of nurses were 53 (39, 65) and 30 (25, 33) respectively. The scores of the EBP Beliefs Scale, the EBP Implementation Scale, and the EBP Organizational Culture and Readiness Scale were 9 (8, 10), 9 (7, 9), and 9 (6, 9), respectively. Multiple linear regression analysis showed that the main influencing factors of evidence-based nursing competence of oncology nurse specialists were nurse innovation behavior, evidence-based practice organizational culture and readiness, frequency of reading specialized literature, and duration of evidence-based nursing training ( P<0.05), which could explain 34.6% of the total variation. Conclusions:The evidence-based nursing competence of oncology nurse specialists needs to be improved.

Purpose: Radiation-induced dermatitis (RD) is a common side-effect of therapeutic ionizing radiation that can severely affect patient quality of life. This study aimed to develop a risk prediction model for the occurrence of RD in patients with cervical carcinoma undergoing chemoradiotherapy using electronic medical records (EMRs). Methods: Using EMRs, the clinical data of patients who underwent simultaneous radiotherapy and chemotherapy at a tertiary cancer hospital between 2017 and 2022 were retrospectively collected, and the patients were divided into two groups: a training group and a validation group. A predictive model was constructed to predict the development of RD in patients who underwent concurrent radiotherapy and chemotherapy for cervical cancer. Finally, the model's efficacy was validated using a receiver operating characteristic curve. Results: The incidence of radiation dermatitis was 89.5% (560/626) in the entire cohort, 88.6% (388/438) in the training group, and 91.5% (172/188) in the experimental group. The nomogram was established based on the following factors: age, the days between the beginning and conclusion of radiotherapy, the serum albumin after chemoradiotherapy, the use of single or multiple drugs for concurrent chemotherapy, and the total dose of afterloading radiotherapy. Internal and external verification indicated that the model had good discriminatory ability. Overall, the model achieved an area under the receiver operating characteristic curve of .66. Conclusions The risk of RD in patients with cervical carcinoma undergoing chemoradiotherapy is high. A risk prediction model can be developed for RD in cervical carcinoma patients undergoing chemoradiotherapy, based on over 5 years of EMR data from a tertiary cancer hospital.

Objective:To evaluate the effect of imatinib on the endotoxemia-induced acute lung injury in mice.Methods:Sixty SPF male, 8-12 weeks, C57BL/6 mice were randomly (random) divided into 4 groups ( n=15 each): control group (group C), imatinib group (groupⅠ), endotoxemia group (group LPS) and imatinib + endotoxemia group (group I+LPS). The endotoxemia model of acute lung injury was established. After 24 hours, the mice were sacrificed. The pathological changes of lung tissues were evaluated, the lung injury scores were calculated, and the wet/dry ratios of lung tissues were measured. ELISA was used to detect the levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in serum. Detection kits were used to analyze the levels of malondialdehyde (MDA), glutathione (GSH), catalase (CAT), superoxide dismutase (SOD) and the ratio of reduced glutathione to oxidized glutathione (GSH/GSSG) in lung tissues; The expression levels of phosphorylated nuclear factor-kappa B (p-NF-κB), nuclear factor-erythroid 2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) in lung tissues were analyzed by western blotting. Results:Compared with the group C, the wet/dry (W/D) ratio of lungs [(3.47±0.41) vs. (5.58±0.47)], lung injury scores [(1.25±0.89) vs. (10.25±1.75)], and the levels of TNF-α and IL-6 in serum increased in the group LPS ( P<0.05). The levels of SOD, CAT, GSH and GSH/GSSG decreased, the level of MDA increased, and the expression of p-NF-κB, Nrf2 and HO-1 protein up-regulated ( P<0.05). Compared with the LPS group, the W/D ratio of lungs [(5.58±0.47) vs.(4.62±0.38)] and lung injury scores [(10.25±1.75) vs. (7.00±1.31)] in the I+LPS group decreased ( P<0.05), and the levels of TNF-α and IL-6 in the serum decreased ( P<0.05). In lung tissues, the levels of SOD, CAT, GSH and GSH/GSSG increased (all P<0.05), the level of MDA decreased (all P<0.05), the expression of p-NF-κB protein decreased, and the expression of Nrf2 and HO-1 protein increased ( P<0.05). Conclusions:Imatinib improves sepsis-induced acute lung injury in mice, and the mechanism of actions behind may be related to the inhibition of oxidative stress.
