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.

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.

ObjectiveTo evaluate the effects of modified Baohe Pill （保和丸） formula added to conventional pulmonary rehabilitation on thoracic drainage volume， chest tube duration， and peripheral blood inflammatory indices after video-assisted thoracoscopic surgery （VATS） for lung cancer. MethodsIn this randomized parallel-controlled study， 118 post-VATS patients were enrolled， with 59 cases in each group. The control group received conventional pulmonary rehabilitation， while the treatment group additionally received an oral decoction of modified Baohe Pill formula until chest tube removal and discharge. The primary outcome was total postoperative thoracic drainage volume， while the secondary outcomes included chest tube duration and inflammatory indices including the pre-treatment and post-treatment levels and relative changes in platelet-to-lymphocyte ratio （PLR）， neutrophil-to-lymphocyte ratio （NLR）， lymphocyte-to-monocyte ratio （LMR）， systemic immune-inflammation index （SII）， aggregate index of systemic inflammation （AISI）， and systemic inflammation response index （SIRI）. Adverse events during the treatment period were recorded. ResultsThe total postoperative thoracic drainage volume was 850 （430， 1410） ml in the treatment group， lower than 1085 （660， 1720） ml in the control group （P＜0.05）. Total postoperative chest tube duration was 8 （6， 11） days in the treatment group， shorter than 10 （7， 11） days in the control group （P＜0.05）， whereas the interval from enrollment to removal did not differ significantly between groups （P＞0.05）. The postoperative NLR in the treatment group was lower than that in the control group， and the relative change in NLR was greater than that in the control group （P＜0.05）. No significant between-group differences were found in post-treatment levels or relative changes of the other five inflammatory indices （P＞0.05）. No treatment-related serious adverse events were reported in either group. ConclusionModified Baohe Pill formula plus conventional pulmonary rehabilitation has lower total postoperative thoracic drainage volume， shorter total postoperative chest tube duration， and lower NLR levels in lung cancer patients following VATS， while demonstrating a more favorable safety profile than conventional pulmonary rehabilitation alone.

Objective: Adolescent depression is a highly prevalent and disabling mental disorder with unclear pathophysiology and unfavorable treatment outcomes. Recent efforts have been focusing on searching for biomarkers as specific indicators of adolescent depression. We performed a systematic literature review and meta-analysis, specifically including studies with healthy control groups as an inclusion criterion. This approach helps to avoid confounding factors and provides more accurate results regarding the inflammatory and immune biomarkers associated with adolescent depression. Methods: Three electronic databases were searched for studies comparing the means and changes in the biomarkers between depressed adolescent patients and healthy controls published in English until February 2024. Two authors independently performed the screening, quality assessment, and data extraction of the studies. A meta-analysis was conducted on outcomes reported by two or more studies using a random-effects model and presented Forrest plots and test statistics (I2) for heterogeneity analysis. Results: Nine studies were included in the review, including seven case-control studies and two cross-sectional studies. These studies included 24 target biomarkers, 13 of which were quantified in 2 or more studies. Compared to the healthy controls, the depressed adolescents had significantly higher values in ten indicators. Additionally, the depressed adolescents had lower procalcitonin levels than the healthy controls. The two groups showed no significant differences in the remaining 13 biomarkers. Conclusion Our findings offer fresh insights into the pathophysiology of inflammatory and immune aspects of adolescent depression and provide helpful guidance in developing targeted and effective intervention and prevention strategies to address adolescent depression.

Based on the theory of "three regions and sanjiao" in traditional Chinese medicine (TCM), the acupuncture-moxibustion differentiation and treatment system is explored and constructed for spasm syndrome, so as to provide a clearer guiding framework for TCM treatment of spasm syndrome. This disorder is caused essentially by the invasion of pathogenic wind, and located in brain marrow. The key regions of illness cover five zang organs and five tissues, and the core pathogenesis is associated with wind disturbance in brain marrow. In differentiation, spasm syndrome refers to overall transmission (from the upper to the lower) and local transmission (from exterior to interior). This disorder can be classified into sanjiao spasm (heart-lung spasm of the upper jiao, liver-spleen spasm of the middle jiao, and liver-kidney spasm of the lower jiao) and three-region spasm (skin-vessel spasm of the upper region, tendon-muscle spasm of the middle region, and tendon-bone spasm of the lower region). Based on "three regions and sanjiao" theory of acupuncture and moxibustion, 7 "expelling-wind" points can be selected in terms of the etiology of this disease. Baihui (GV20)-toward-Taiyang (EX-HN5) needling is applied to regulate the brain marrow, focusing on the core location of illness; and regarding the key location of illness, the combination of back-shu and front-mu points and that of jing-well and xing-spring points are adopted to regulate five zang organs. The five needling techniques (half needling, leopard-spot needling, joint needling, Hegu needling and shu needling) are used to regulate five tissues.

BACKGROUND: Disease-modifying therapies have been approved for the treatment of relapsing multiple sclerosis (RMS). The present study aims to examine the safety of teriflunomide in Chinese patients with RMS. METHODS: This non-randomized, multi-center, 24-week, prospective study enrolled RMS patients with variant (c.421C>A) or wild type ABCG2 who received once-daily oral teriflunomide 14 mg. The primary endpoint was the relationship between ABCG2 polymorphisms and teriflunomide exposure over 24 weeks. Safety was assessed over the 24-week treatment with teriflunomide. RESULTS: Eighty-two patients were assigned to variant ( n  = 42) and wild type groups ( n  = 40), respectively. Geometric mean and geometric standard deviation (SD) of pre-dose concentration (variant, 54.9 [38.0] μg/mL; wild type, 49.1 [32.0] μg/mL) and area under plasma concentration-time curve over a dosing interval (AUC tau ) (variant, 1731.3 [769.0] μg∙h/mL; wild type, 1564.5 [1053.0] μg∙h/mL) values at steady state were approximately similar between the two groups. Safety profile was similar and well tolerated across variant and wild type groups in terms of rates of treatment emergent adverse events (TEAE), treatment-related TEAE, grade ≥3 TEAE, and serious adverse events (AEs). No new specific safety concerns or deaths were reported in the study. CONCLUSION: ABCG2 polymorphisms did not affect the steady-state exposure of teriflunomide, suggesting a similar efficacy and safety profile between variant and wild type RMS patients.
