Abstract To understand the impact of negative behavior patterns on the physical and psychological health of secondary vocational school students, the study systematically reviews the multidimensional and co-occurring characteristics of behavioral risk aggregation with physical and psychological health problems among secondary vocational school students, analyzes the intertwined influence of new and traditional behavioral risk factors, and explores a comprehensive intervention framework centered on multidimensional rhythm reshaping and individual-family-school-society multi level intervention pathways, providing theoretical reference for promoting the health of secondary vocational school students.

Objective:To estimate the economic burden of 14 chronic diseases among middle-aged and elderly people in China.Methods:This cross-sectional study was based on longitudinal data from five waves (2011 to 2020) of the China Health and Retirement Longitudinal Study (CHARLS). Participants aged 45 and over who had been diagnosed with exactly one target chronic disease were included in the study. The 14 chronic diseases included: hypertension, dyslipidemia, diabetes or elevated blood glucose, malignant tumors, chronic pulmonary diseases, liver diseases, heart diseases, stroke, kidney diseases, digestive system diseases, emotional and mental diseases, memory-related diseases, arthritis or rheumatic diseases, and asthma. The economic burden of disease was measured in terms of both direct and indirect economic burden, with the results adjusted using a healthcare-specific Consumer Price Index (CPI). The direct economic burden included direct medical and non-medical burden. The human capital method was employed to calculate the indirect economic burden. A generalized linear mixed model (GLMM) was conducted to compare the differences in the economic burden between urban and rural areas, with provinces and prefecture-level cities set as random effects and residence (urban or rural areas) as fixed effects to control for the effects of geographic hierarchical structure. Gender, age and educational attainment were also included as covariates to control for confounding factors. The model′s robustness was assessed by comparing the significance of urban-rural differences before and after adding the covariates.Results:The median annual economic burden of the 14 chronic diseases among the middle-aged and elderly population in China ranged from 7 565 to 17 174 CNY, of which the direct economic burden ranged from 6 909 to 16 565 CNY, and the indirect burden ranged from 284 to 1 276 CNY. The direct economic burden was primarily driven by direct medical burden (83.67% to 95.01% of direct economic burden). Out-of-pocket expenses for outpatient medical burden ranged from 50% to 100%, while those for inpatient ranged from 36.30% to 61.29%. GLMM analysis revealed no statistically significant difference in the overall economic burden between urban and rural areas across diseases. However, the burden of inpatient medical burden for arthritis or rheumatism was higher in urban areas than in rural areas (5 338 vs. 3 898 CNY; LR=6.04, P=0.014). Similarly, the burden of self-treatment for hypertension was also higher in urban areas than in rural areas (324 vs. 238 CNY; LR=8.30, P=0.004). The outpatient non-medical burden for diabetes or elevated blood glucose (59 vs. 149 CNY; LR=5.99, P=0.014), stroke (0 vs. 307 CNY; LR=4.55, P=0.033), and digestive system diseases (45 vs. 107 CNY; LR=9.58, P=0.002) was lower in urban areas than rural. Conclusions:Chronic diseases cause heavy economic burden on middle-aged and elderly people in both urban and rural areas of China, with direct economic burden accounting for the majority of expenditure. The outpatient medical burden accounts for a higher proportion of out-of-pocket expenses than the inpatient.

Objective:To compare the clinical effects of plasma exchange（PE）combined with continuous veno-venous hemodiafiltration（CVVHDF）at different time points in children with Kawasaki disease shock syndrome（KDSS）.Methods:Thirty-five children with KDSS admitted to the intensive care unit of Hunan Children's Hospital from January 2018 to December 2022 were enrolled.According to whether PE combined with CVVHDF was performed within 24 hours after reaching the blood purification criteria for KDSS，the patients were divided into the early treatment group(8 cases) and the control group (27 cases).The clinical and laboratory indicators and prognosis were compared between the two groups.Results:There were no statistically significant differences in age，gender，mean arterial pressure，and pediatric critical illness score between the two groups before treatment（ P>0.05）.In the early treatment group,the vasoactive inotropic score (VIS) gradually decreased,and was significantly lower than that in the control group after 24 hours of treatment.The duration of vasopressor use，pediatric logistic organ dysfunction score（PELOD），inflammatory markers，total hospitalization time，and PICU stay were all lower in the early treatment group than in the control group（ P<0.05）.The incidence of coronary artery involvement within 6 months post-discharge was lower in the early treatment group than in the control group（ P<0.05）.Among the 12 children who underwent PE combined with CVVHDF，four cases were in the late treatment group.The duration of CVVHDF，PICU stay，and PELOD scores were lower in the early treatment group than in the late treatment group（ P<0.05）.Additionally，the concentrations of interleukin-6，tumor necrosis factor-α，heparin-binding protein，and N-terminal pro-brain natriuretic peptide before PE were lower in the early treatment group than in the late treatment group（ P<0.05）. Conclusion:Early PE combined with CVVHDF treatment for KDSS patients can reduce inflammatory response，shorten the course of the disease，and reduce the duration of vasopressor use.However，most patients' conditions can be controlled with active conventional treatment.

Objective:To comprehensively assess the nutritional literacy among family caregivers of elderly patients with chronic heart failure (CHF), so as to provide reference for developing clinical nutrition management strategies for elderly CHF patients.Methods:This study was a descriptive qualitative research. From February to March 2025, purposive sampling was used to select 17 family caregivers of elderly CHF patients at Affiliated Hospital of Yangzhou University as research subjects for semi-structured interviews. The data was analysed using a directed content analysis approach.Results:Three themes and nine subthemes were identified, including functional nutrition literacy (lack of disease-related nutrition knowledge, difficulty in knowledge transformation and utilization, and barriers to voluntary nutritional adherence), interactive functional literacy (limited channels for accessing nutrition information, broken healthcare services, insufficient motivation for proactive communication, and demand for professional dietary guidance), and critical nutrition literacy (challenges in distinguishing information authenticity, reliance on inherent cognition for evaluation) .Conclusions:Family caregivers of elderly patients with CHF commonly lack relevant nutritional knowledge. Healthcare providers should attach importance to the education of nutrition knowledge and skills for family caregivers, establish a multidimensional nutrition education system, develop personalized nutrition guidance plans, and integrate the family-community-medical collaborative support network to systematically strengthen caregivers' understanding of disease nutrition management for elderly CHF patients and enhance their compliance with nutrition care practices.

Objective To investigate the prognosis of patients with triple-negative invasive lobular carcinoma (TN-ILC) undergoing breast-conserving surgery combined with radiotherapy (BCS+RT) versus total mastectomy. Methods A retrospective analysis was performed for 2 386 female patients with TN-ILC who underwent surgery in the SEER database from 2006 to 2018, and the baseline characteristics (age, histological grade, AJCC stage, etc.) were balanced by propensity score matching (PSM, 1∶1, caliper value 0.02), and breast cancer-specific survival (BCSS) and overall survival (OS) were compared by Kaplan-Meier method and COX regression analysis. Results A total of 1 056 pairs of patients were obtained after PSM, and the BCS+RT group had significantly better BCSS and OS than the total mastectomy group (both P<0.001). Stratified analyses showed that BCS+RT had a survival advantage in all subgroups except histologic grade Ⅰ and tumor stage Ⅰ. Multivariate analysis confirmed that BCS+RT was an independent protective factor (BCSS: HR=0.682, OS: HR=0.607, both P<0.001). Conclusions BCS+RT significantly improves survival compared with total mastectomy in patients with TN-ILC, supporting BCS+RT as the preferred treatment strategy for eligible patients.

Objective:To deeply understand newly employed nurses' cognition and experience of reflective practice (RP) and explore its application in clinical settings, providing a scientific basis for constructing an RP training system.Methods:A descriptive phenomenological research method was used, with purposive sampling to select newly employed nurses from the Affiliated Hospital of Yangzhou University between October and December 2023. Semi-structured interviews were conducted, and traditional content analysis was used to analyze the data.Results:Fourteen newly employed nurses were interviewed, including 3 males and 11 females, aged 22-25 (22.92 ± 0.92) years old. A total of 190 000 words of interview data were transcribed. Four themes and eight sub-themes were extracted: understanding of RP, attitudes toward RP, differences in RP abilities, and challenges in the clinical application of RP.Conclusions:Newly employed nurses have some understanding of RP, but there are issues such as insufficient learning pathways, negative attitudes toward RP, differences in RP abilities, and challenges in clinical application. RP learning should be incorporated into the training of newly employed nurses to promote the improvement of their RP abilities.
