BackgroundAnxiety exhibits a rising prevalence among college students. Investigating the mechanisms through which family function relates to anxiety and examining the moderating role of emotion regulation strategies within this context hold substantial implications for promoting mental health among college students. However， existing research has not sufficiently elucidated the complex interplay among family function， emotion regulation， and anxiety among college students. Further research is warranted to clarify the underlying mechanisms linking family function to anxiety outcomes and to examine the potential moderating role of emotion regulation strategies in this causal pathway. ObjectiveTo explore the relationship between family function and anxiety among lower-grade college students， and to validate the moderating role of emotion regulation strategies in this relationship， thereby offering evidence-based insights for anxiety reduction interventions in this population. MethodsIn March 2023， a total of 1 980 first- and second-year students from a comprehensive university in Shanghai were selected using the cluster sampling method. A self-designed demographic questionnaire， the Emotion Regulation Questionnaire （ERQ）， the Family Adaptability and Cohesion Evaluation Scale Ⅱ-Chinese Version （FACES Ⅱ-CV）， and the Symptom Checklist-90 （SCL-90） were utilized for assessment. Pearson correlation analysis and Spearman correlation analysis were employed to test the correlations of each variable. Hierarchical linear regression analysis was conducted to certify the moderating role of emotion regulation strategies in the relationship between family function and anxiety. ResultsCompared with female students， male students scored significantly lower on ERQ cognitive reappraisal （t=-5.793， P<0.01） but significantly higher on ERQ expressive suppression （t=8.359， P<0.01）. For lower-grade college students， scores on adaptability and cohesion subscales of FACES Ⅱ-CV showed a positive association with cognitive reappraisal in ERQ （r=0.251， 0.302， P<0.01）， while simultaneously displaying negative correlations with both expressive suppression in ERQ （r=-0.113， -0.154， P<0.01） and anxiety in SCL-90 （r=-0.243， -0.202， P<0.01）. Notably， anxiety scores in SCL-90 were inversely related to cognitive reappraisal scores in ERQ （r=-0.159， P<0.01） but directly associated with expressive suppression scores in ERQ （r=0.171， P<0.01）. Hierarchical regression analysis indicated that cognitive reappraisal significantly moderated the relationship between family cohesion and anxiety （β=-0.421， P<0.01）. ConclusionThe cognitive reappraisal strategy serves as a moderator in the relationship between family cohesion and anxiety， potentially mitigating the escalation of anxiety levels associated with family dysfunction. ［Funded by Science and Technology Development Fund of Shanghai Pudong New Area （number， PKJ2023-Y21）］

In recent years， repetitive transcranial magnetic stimulation （rTMS） has garnered significant attention as a therapeutic approach for sleep disorders in the elderly. However， the prevailing rTMS protocols are predominantly developed based on normative neurophysiological data derived from young adults and fail to incorporate individualized parameters tailored to the brain characteristics of the elderly. To address this gap， the consensus development group synthesized the latest evidence from 2010 to 2025 and established a standardized rTMS protocol specifically for elderly patients with sleep disorders. Adhering to the Appraisal of Guidelines for Research and Evaluation II （AGREE II） framework， systematically screened randomized controlled trials （RCTs） and systematic reviews regarding rTMS in the treatment of sleep disorders across various conditions. Meanwhile， the Grading of Recommendations Assessment， Development and Evaluation （GRADE） system was employed to rigorously grade the quality of evidence and the strength of recommendations. This consensus guideline delineates precise rTMS protocols for the management of sleep disorders in the elderly， highlights the adjustment of stimulation intensity according to scalp-cortex distance recommends either MRI‑guided neuronavigation or the Beam F3/F4 heuristic approach for accurate target localization， thereby providing precise rTMS intervention protocol for sleep disorders in the elderly， aiming to enhance clinical efficacy while ensuring treatment safety. ［Funded by National Key Research and Development Program （number， 2023YFC3603200）； General Program of Shenzhen Science and Technology Innovation Commission （number， JCYJ20240813112859008， JCYJ20240813112900002）； Youth Program of Shenzhen Kangning Hospital （number， KN2023A004）； www.guidelines-registry.cn number， PREPARE-2026CN530］

Metabolic associated fatty liver disease （MAFLD） is a highly prevalent chronic liver disease worldwide， and the mechanism underlying its progression to metabolic associated steatohepatitis and liver fibrosis remain unclear. Endoplasmic reticulum stress （ERS） and ferroptosis （Fer） are deeply involved in the pathological evolution of MAFLD. This article systematically reviews the core regulatory mechanisms of ERS and its role in regulating lipid metabolism， inflammation response， and cell apoptosis in MAFLD. It also analyzes the core mechanism of Fer and discusses the predisposing factors for Fer in the pathological microenvironment of MAFLD， as well as the role of Fer in exacerbating hepatocyte death and activating the progression of liver fibrosis. This article proposes that the crosstalk between ERS and Fer is a key driver for the progression of MAFLD， which provides new references and ideas for the clinical intervention of MAFLD.

Objective: To assess the current status of knowledge, attitude, and practice (KAP) regarding health protection against air pollution among primary school students in China, and to analyze the impacts of fine particulate matter (PM 2.5 ) exposure, family, and individual factors on KAP levels, so as to provide empirical basis for implementing targeted interventions. Methods: Using stratified cluster random sampling method, a questionnaire survey was conducted among 19 297 primary school students from third to fifth grade across 30 provinces (autonomous regions and municipalities directly under the central government) in China in 2024. The questionnaire was developed based on the Technical Guidelines for the Assessment of Civic Environmental and Health Literacy (Trial), and encompasses three dimensions:knowledge, attitude, and practice. Spearman correlation analysis, Chi-square test, multivariate Logistic regression, and Bootstrap mediation effect test was applied for data analysis. Results: The overall mean KAP score for health protection against air pollution among primary school students was (79.73±13.53), with an adequacy rate of 80.47% ( n =15 528). The dimension scores for knowledge, attitude, and practice were (41.34±8.01, 16.43± 2.61 ), and (21.97±5.71), respectively. Knowledge was positively correlated with attitude and practice, and attitude was positively correlated with practice ( r =0.51, 0.35, 0.32, all P <0.01). Multivariate Logistic regression showed that the northeast region ( OR =2.36, 95% CI =2.02-2.75), having parents with a bachelor s degree or higher ( OR =4.76, 95% CI =2.71-8.37), living with both parents ( OR =1.33, 95% CI =1.15-1.55), being in the fifth grade ( OR =1.22, 95% CI =1.11-1.33), outdoor PM 2.5 level exceeding standard limits at the survey site ( OR =1.25, 95% CI =1.16-1.34), history of allergy ( OR =1.47, 95% CI =1.31-1.64), and wearing masks during heavily polluted weather ( OR =1.19, 95% CI =1.07-1.31) were promoting factors for KAP adequacy rate (all P <0.05). Conversely, obesity was a detrimental factor ( OR =0.78, 95% CI =0.69-0.88, all P <0.05). Conclusions Primary school students in China exhibit a favorable KAP level regarding health protection against air pollution, though regional, familial, and individual disparities persist. Exposure to PM 2.5 levels exceeding standard limits exerts a direct positive effect on enhancing health protection literacy. Future efforts should focus on the western region, families with lower educational attainment children to implement tailored, stratified interventions.

Objective: To examine the association between academic stress and anxiety-depression comorbidity among college students and the potential moderating effect of physical activity, so as to provide a theoretical basis for the development of evidence based mental health promotion frameworks in higher education institutions. Methods: From October 2022 to June 2024, a total of 7 980 students from 21 universities across five provinces/municipalities in China, including Shanghai, Jiangsu, Zhejiang, Shandong, and Anhui, using a combination of convenience sampling and stratified random cluster sampling. Physical activity, academic stress, anxiety, and depression were assessed by using the 24 hour Movement Behaviors Questionnaire, the Chinese College Students Mental Health Screening Scale, the Generalized Anxiety Disorder-7, and the Center for Epidemiologic Studies Depression Scale, respectively. Binary Logistic regression was used to examine the associations between academic stress and anxiety, depression, and their comorbidity. The PROCESS macro was employed to test the moderating effect of physical activity. Results: The prevalence of anxiety-depression comorbidity among college students was relatively high (11.53%), with significant differences observed across grades and body mass index (BMI) categories ( χ 2=70.30, 24.63, both P <0.01). Binary Logistic regression revealed that, compared with low academic stress, moderate academic stress among male students was significantly associated with greater odds of anxiety ( OR =2.78), depression ( OR =2.75), and anxiety-depression comorbidity ( OR =2.89) (all P <0.01). High academic stress was associated with elevated odds of anxiety ( OR =6.66), depression ( OR =12.81), and anxiety-depression comorbidity ( OR =13.65) (all P <0.01). Among female students, moderate academic stress was associated with anxiety ( OR =2.58), depression ( OR =1.52), and anxiety-depression comorbidity ( OR =1.70) (all P <0.01). High academic stress increased the risk of anxiety ( OR =6.77), depression ( OR =6.81), and anxiety-depression comorbidity ( OR =7.48) (all P <0.05). The moderation analysis indicated that the interaction between total physical activity duration and academic stress had a significant netative moderating effect on anxiety-depression comorbidity among college students ( β =-0.03, P <0.01). Conclusions Academic stress increases the risk of anxiety, depression, and anxiety-depression comorbidity among college students. Physical activity may attenuate the adverse effects of academic stress on anxiety-depression comorbidity.

With the accelerating aging of the population, the proportion of elderly patients with lung cancer continues to rise, presenting multiple challenges to perioperative management. This paper systematically reviews the clinical characteristics of elderly lung cancer patients. Based on the comprehensive geriatric assessment, it proposes incorporating seven major geriatric syndromes—frailty, delirium, sarcopenia, cognitive impairment, malnutrition, dysphagia, and mood disorders—into the core evaluation system. By integrating multimorbidity management with complication prevention and control, an integrated "geriatric syndrome-multimorbidity-complication" perioperative management model is constructed. Furthermore, this paper outlines stratified intervention strategies for geriatric syndromes, a "five-step" workflow for comorbidity management, and a comprehensive intervention pathway for complications across the preoperative, intraoperative, and postoperative phases. Multidisciplinary team (MDT) collaboration serves as the core mechanism to achieve individualized comprehensive treatment. This paper aims to provide a novel perioperative comprehensive treatment model for elderly lung cancer patients, which is centered on geriatrics, supported by multidisciplinary collaboration, and guided by precision medicine.

Integrating healthy life expectancy (HLE) into the national health assessment system is a key institutional arrangement for advancing the Healthy China Strategy from a disease-centered to a health-centered paradigm. From 2000 to 2021, China's life expectancy (LE) increased by an average of 0.39% annually, while HLE increased by 0.36%. The absolute gap between LE and HLE widened from 7.7 to approximately 10.4 years, and the HLE/LE ratio declined slightly from 89.2% to 87.7%, reflecting an expansion of morbidity. These data reveal that the current LE-oriented assessment system has institutionalized an incentive structure that overemphasizes diagnosis and treatment while neglecting prevention and rehabilitation, representing one of the key institutional roots of the slower growth in HLE compared to LE. However, integrating HLE into the assessment system faces four systemic barriers, including inconsistent indicator definitions and measurement standards, difficulties in attributing intervention effects, fragmented cross-sectoral governance, and unclear pathways to achieving health equity. Accordingly, a “stratified, classified, and multi-dimensional” HLE assessment framework has been constructed, clarifying the three-level assessment hierarchies (national-provincial-municipal/county) and multi-departmental responsibility allocation, and proposing some digital-intelligent support pathways including artificial intelligence (AI)-assisted dynamic monitoring, digital twin interventions, healthy city intelligent ecosystems, and AI equity initiatives, so as to provide a referential pathway for advancing HLE from a monitoring concept to a governance tool.

ObjectiveStroke remains the leading cause of acquired disability in adults worldwide, imposing a substantial socioeconomic burden on patients, families, and healthcare systems. Among the various neurological deficits caused by stroke, motor dysfunction——particularly contralateral hemiplegia——is the most common and debilitating consequence, and it predominantly results from damage to the cortical motor conduction pathways. When motor cortex neurons or their projecting fibers are damaged, the distal axons and their associated myelin sheaths undergo a series of progressive, programmed degeneration, fragmentation, and eventual phagocytic clearance. This pathological process is termed Wallerian degeneration (WD). However, the temporal progression of WD following ischemic stroke and the associated alterations in the local glial microenvironment remain incompletely understood. The present study was designed to systematically elucidate the time course of corticospinal tract (CST) axonal WD after ischemic stroke in mice, and to simultaneously characterize the dynamic pathological changes of astrocytes, microglia, oligodendrocyte lineage cells, and myelinating oligodendrocytes during the WD process. MethodsEight-week-old male C57BL/6J mice were randomly assigned to control and ischemic stroke groups. A focal cortical ischemic stroke model was established in the right sensorimotor cortex using the photothrombotic method. This method induces localized intravascular thrombosis in the target cortical region through precisely controlled interaction between the photosensitizer and laser light of specific wavelength. At day 1 post‑surgery, 2,3,5-triphenyltetrazolium chloride (TTC) staining was performed to evaluate infarct volume, hematoxylin and eosin (HE) staining for histopathological examination, and Nissl staining for assessment of neuronal injury. For axonal degeneration time-course analysis, rAAV-CAG-mCherry anterograde viral tracing was employed to specifically label CST neurons. Cervical spinal cord sections at the CST region were collected at day 3, 5, 7, 14, and 60 post-injury. Morphological changes of mCherry-positive CST fibers were observed under fluorescence microscopy, and the fluorescence signal area fraction within the defined region was quantitatively analyzed to evaluate the dynamic process of axonal degeneration. For glial response assessment, immunofluorescence staining against Iba1 (microglia), GFAP (astrocytes), Olig2 (oligodendrocyte lineage cells), and APC (myelinating oligodendrocytes) was performed at day 7, 14, and 60 post‑surgery. The numbers of positive cells were counted to quantitatively analyze the dynamic changes in each glial population at different time points after ischemia, thereby revealing the evolution of the glial microenvironment during WD. ResultsThe photothrombotic method stably and reliably established an ischemic brain injury model confined to the sensorimotor cortex. Viral tracing revealed that the proportion of mCherry‑positive CST fibers was significantly reduced at day 7 after ischemic injury to the neuronal soma. Immunofluorescence staining demonstrated that during WD, the numbers of microglia and astrocytes in the CST region were significantly increased, whereas the numbers of oligodendrocyte lineage cells and myelinating oligodendrocytes showed no significant changes. ConclusionWD of CST axons is observed at day 7 post-ischemic stroke in a delayed manner. This degenerative process selectively activates microglia and astrocytes, while leaving the number of oligodendrocyte lineage cells largely unaffected.

Objective To investigate the safety, economic benefits and psychological effects of day breast conserving surgery for breast cancer. Methods The demographic data and clinical data of breast cancer patients undergoing day (day surgery group) and ward (ward surgery group) breast conserving surgeries in West China Hospital of Sichuan University from March 2020 to June 2021 were retrospectively collected; the demographic data, clinical data, medical and related transportation costs, and preoperative and postoperative BREAST-Q scores of breast cancer patients undergoing day (day surgery group) and ward (ward surgery group) breast conserving surgery in West China Hospital of Sichuan University from June 2021 to June 2022 were prospectively collected. The safety, economic benefit, and psychological satisfaction of day surgery was analyzed. Results A total of 42 women with breast cancer were included in the retrospective study and 39 women with breast cancer were included in the prospective study. In both prospective and retrospective studies, the mean age of patients in both groups were <50 years. There were only statistical differences between the two groups in the aspects of hypertension (P=0.022), neoadjuvant chemotherapy (P=0.037) and postoperative pathological estrogen receptor (P=0.033) in the prospective study. In postoperative complications, there were no statistical differences in the surgical-related complications or anesthesia-related complications between the two groups in either the prospective study or the retrospective study (P>0.05). In terms of the overall cost, we found that the day surgery group was more economical than the ward surgery group in the prospective study (P=0.002). There were no statistical differences in postoperative psychosocical well-being, sexual well-being, satisfaction with breasts or chest condition between the two groups (P>0.05). Conclusion It is safe and reliable to carry out breast conserving surgery in day surgery center under strict management standards, which can save medical costs and will not cause great psychological burden to patients.

TCM believes that the main pathogenesis of gastrointestinal dysfunction (GD) after laparoscopic cholecystectomy (LC) is spleen and stomach weakness, liver and stomach disharmony, liver depression and spleen deficiency, and intestinal depression. Moxibustion in the treatment of GD after LC can avoid the aggravation of gastrointestinal burden caused by oral drugs. The intervention methods mainly include suspension moxibustion, umbilical moxibustion, heat sensitive moxibustion, thunder fire moxibustion, warm acupuncture, partition moxibustion, etc. Moxibustion is often performed on the acupoints in liver meridian, spleen meridian, stomach meridian, small intestine meridian, large intestine meridian and Conception Vessel, such as Taichong (LR3), Ganshu (BL18), Yinlingquan (SP9), Zusanli (ST36), Tianshu (ST25), Wangu (SI4), Hegu (LI4), Zhongwan (CV12), Shenque (CV8) and Qihai (CV6). At present, most studies combined with moxibustion on the basis of conventional Western medicine treatment can significantly improve the efficacy, and have certain advantages in improving gastrointestinal motility decline, intestinal flora imbalance, first exhaust time, gastrointestinal hormone level disorder and intestinal mucosal barrier dysfunction. However, there are still some problems in the existing research: small sample size of clinical research, not perfect scoring scale, not unified treatment plan and operation standard, relatively scarce basic research, relatively simple acupoint research, lack of biochemical evaluation indicators, and the research of national moxibustion needs to be explored and improved in the future.
