Doxorubicin (DOX)-induced cardiotoxicity and sepsis-induced myocardial injury (SIMI) represent significant clinical challenges in patients undergoing chemotherapy, sharing a common pathological basis of oxidative stress and mitochondrial dysfunction. Ferroptosis, an iron-dependent form of regulated cell death driven by lipid peroxidation, has recently been shown to play a critical role in DOX-induced cardiotoxicity and lipopolysaccharide (LPS)-induced SIMI. This article systematically reviews the mechanisms underlying myocardial injury caused by DOX and sepsis, identifying ferroptosis as a central common pathway. DOX triggers a burst of reactive oxygen species within mitochondria and inhibits glutathione peroxidase 4 (GPX4) activity through redox cycling of its quinone group and high-affinity accumulation in mitochondrial cardiolipin. LPS, by activating pattern recognition receptors and related inflammatory signaling pathways, provokes a cytokine storm and mitochondrial dysfunction. Both can disrupt the core regulatory axis of cysteine-glutathione (GSH)-GPX4, synergistically promoting ferroptosis in cardiomyocytes. Moreover, epigenetic regulation plays a key role in DOX- and LPS-induced cardiomyocyte ferroptosis and may serve as a promising therapeutic target. A deeper understanding of the ferroptosis mechanism and its epigenetic regulatory network in the synergistic injury induced by DOX and sepsis is of great importance for developing novel strategies to mitigate chemotherapy-related cardiotoxicity and improve outcomes in cancer patients with concurrent infections.

Objective:
To explore the association of vegetables and fruits intake with depressive symptoms among multi ethnic first year junior high school students in Yunnan Province, so as to provide data support for preventing and reducing depressive symptoms among first year junior high school students.
Methods:
From October to December 2022, a cluster random sampling method was used to select 8 500 first year junior high school students from 11 ethnic minority areas in Yunnan Province (Fugong County, Longling County, Longyang District, Luchun County, Mojiang County, Nanjian County, Qiaojia County, Shuangjiang County, Tengchong City, Yuanmou County, Zhenyuan County), to investigate with a questionnaire. The Dietary Frequency Questionnaire was used to collect dietary behavior datas, and the Chinese version of Depression Anxiety Stress Scale-21 (DASS-21) was used to assess depressive symptoms. The generalized linear model was used to analyze the association of vegetable and fruit intake with depressive symptoms in students, and stratified analysis was performed according to ethnicity.
Results:
The detection rate of depressive symptoms among first year junior high school students in Yunnan Province was 29.5%. The detection rates of depressive symptoms in Han and minority first year junior high school students were 26.9% and 31.6%. After controlling for demographic variables such as gender, age, family residence and other confounding factors, the generalized linear model analysis results showed that the intake of leafy vegetables ( β= -0.07 , 95%CI =-0.12 to -0.01), flat fruits ( β=-0.06, 95%CI =-0.12 to -0.00) and hot natured fruits ( β=0.11, 95%CI = 0.04- 0.17) were associated with depressive symptoms in Han first year junior high school students (all P <0.05). The intake of melon and fruit vegetables ( β=-0.06, 95%CI =-0.11 to -0.01) and hot natured fruits ( β=0.06, 95%CI =0.01-0.12) were associated with depressive symptoms in ethnic minority first year junior high school students (both P <0.05).
Conclusions
The intake of vegetables and fruits among multi ethnic first year junior high school students in Yunnan Province is related to the risk of depressive symptoms. It is suggested to strengthen the consumption guidance and education of vegetables and fruits to prevent depressive symptoms among first year junior high school students.

ObjectiveTo construct and validate a clinical prediction model for inflammatory remission outcomes in rheumatoid arthritis (RA) patients with liver and kidney deficiency syndrome treated with Bushen Zhiwang Decoction (补肾治尪汤, BZD) based on metabolomics. MethodsA prospective cohort study was conducted, enrol-ling 60 RA patients with liver and kidney deficiency syndrome. All patients were treated with BZD and conventional-dose oral conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) for 12 months. Clinical data were collected, and the change in disease activity score in 28 joints (DAS28) after treatment compared with baseline (△DAS28) was used as the primary outcome and grouping criterion. Peripheral blood samples were collected before treatment to analyze plasma metabolites. Differential analysis and least absolute shrinkage and selection operator (LASSO) regression were used to preliminarily screen differential metabolites, followed by machine learning algorithms to further identify a core metabolite combination. Based on the expression levels of the core metabolite combination, a novel metabolite index, namely the metabolomics-based inflammatory remission score (Met-IRS), was calculated using standar-dized metabolite values, and its clinical applicability was evaluated. A clinical prediction model was constructed by integrating clinical characteristics and Met-IRS, and the model performance was assessed. ResultsAmong the 60 patients, those with △DAS28 ≥ 0.27 were assigned to the high inflammatory remission group, while those with △DAS28 < 0.27 were assigned to the low inflammatory remission group, with 30 cases in each group. Compared to the low inflammatory remission group, the high inflammatory remission group showed a higher frequency of methotrexate use and a lower positive rate of rheumatoid factor (RF) (P<0.05). Seven core metabolites were identified as the optimal combination, including mangiferic acid, fatty acid-hydroxy fatty acid ester 40∶6, fatty acid-hydroxy fatty acid ester 18∶0, fatty acid-hydroxy fatty acid ester 36∶1, glucosylceramide, lysophosphatidylcholine 22∶5, and pregnanetriol ketone. The calculated Met-IRS comprehensively reflected the characteristics of differential metabolites and demonstrated clinical applicability. Met-IRS was significantly higher in the high inflammatory remission group than in the low inflammatory remission group, and was positively correlated with high inflammatory remission outcomes (P<0.05). Based on the variables Met-IRS, methotrexate use, leflunomide use, and RF positivity, a clinical prediction model for inflammatory remission in RA treatment (Cj-RTRM) was constructed. Model performance evaluation demonstrated that the model had good clinical predictive ability, with an area under the receiver operating characteristic curve (AUC) of 0.880, sensitivity 0.967, specificity 0.700 and Youden's index 0.667. ConclusionThe clinical prediction model Cj-RTRM constructed based on the metabolomics-based inflammatory remission score Met-IRS can effectively predict clinical inflammatory remission outcomes in RA patients treated with BZD and accurately identify the advantageous population for this treatment. This model provides guiding evidence for dynamic inflammation monitoring, targeted management, and identification of populations with advantages in traditional Chinese medicine.

ObjectiveTo compare the clinical efficacy of traditional Chinese medicine (TCM) manipulative reduction combined with small splint fixation versus surgical treatment for type A distal radius fracture (DRF) and to explore the factors influencing the choice of treatment. MethodsA multi-center retrospective study was conducted, collecting data from 1237 type A DRF patients treated in 11 hospitals in Jiangsu province from September, 2023 to April, 2025. Among them, 851 patients in the TCM group received manipulative reduction combined with small splint fixation, and 386 patients in the surgical group underwent open reduction and internal fixation. Visual analog scale (VAS) scores for pain and radiographic indicators including palmar tilt, ulnar deviation, and radial height were compared before treatment, 5-7 days after treatment, and 4-6 weeks after treatment. The wrist joint function scores including Dienst and Gartland-Werley scores at 12 weeks after treatment were recorded. Subgroup analysis was conducted for the excellent rate of Dienst and Gartland-Werley scores, stratified by age (<50, 50-59, 60-69, ≥70 years old) and AO subtypes (A1, A2, A3). A multivariate logistic regression model was used to identify independent factors influencing treatment choice. ResultsOn 5-7 days after treatment, the surgical group had lower VAS scores than the TCM group, while 4-6 weeks after treatment, the TCM group showed lower VAS scores than the surgical group (P<0.01). In terms of radiographic indicators, except for the palmar tilt before treatment being higher in the surgical group than in the TCM group (P<0.01), there were no significant differences in palmar tilt, ulnar deviation, and radial height at other timepoints (P>0.05). Twelve weeks after treatment, the surgical group had a higher average Gartland-Werley score and the excellent rate than the TCM group (P<0.01). Subgroup analysis showed that in patients with A2 type DRF aged 50-59 and 60-69 years old, the excellent rates of Dienst and Gartland-Werley scores in the TCM group were higher than those in the surgical group (P<0.05). Multivariate logistic regression analysis revealed that age, palmar tilt, ulnar deviation, and the degree of swelling on the affected side were independent factors influencing the choice of treatment (P<0.05). ConclusionBoth TCM manipulative reduction combined with small splint fixation and surgical treatment for type A DRF can achieve good therapeutic effects. TCM manipulative reduction combined with small splint fixation has certain advantages in medium- and long-term pain relief, especially in elderly patients, where wrist joint function recovery is more stable. Age, palmar tilt, ulnar deviation, and swelling degree are the main factors influencing the treatment choice.

Chinese Journal of School Health 2025;46(1):18-23
Objective:
To analyze the status of outdoor activities on weekends among children and adolescents of different educational stages in Shanghai and their impact on myopia, so as to provide a basis for formulating more specific prevention and control protocol of myopia.
Methods:
From September to October 2022, a stratified cluster random sampling method was employed to select 84 schools (27 kindergartens, 21 primary schools, 15 junior high schools and 21 high schools) across Shanghai, enrolling a total of 28 654 children and adolescents aged 4 to 18 for the study. Ophthalmic examinations were conducted to ascertain the prevalence of myopia among children and adolescents. Additionally, a questionnaire survey was administered to collect data on outdoor activity duration and associated factors. Multivariate Logistic regression analysis was utilized to investigate the associated factors of outdoor activity levels on weekends.
Results:
The overall myopia detection rate among children and adolescents was 58.4%, with a higher rate observed in girls (59.2%) compared to boys (57.6%). The myopia detection rates for children and adolescents with an average daily outdoor activity duration of ≥2 h and <2 h on weekends were 54.6% and 68.8%, and the differences were statistically significant ( χ 2=8.12,460.89, P <0.01). Multivariable Logistic regression analysis revealed that girls ( OR =0.80), those with a myopic parent ( OR =0.68), schools from urban districts ( OR =0.72), higher education stages (primary school: OR =0.65, junior high school: OR =0.24, high school: OR =0.14) and spending≥2 h/d on homework during weekends ( OR =0.57) among children and adolescents were less likely to engage in outdoor activities for ≥2 h on weekends ( P <0.01). After incorporating gender, parental myopia status, educational stage, school location, average daily duration on weekends for spending on homework, electronic product usage and outdoor activities as dependent variables in a multivariate Logistic regression analysis, the results showed that children and adolescents with an average outdoor activity duration for ≥2 h on weekends had a lower risk of myopia ( OR =0.86, P < 0.01).
Conclusions
The level of outdoor activity among children and adolescents on weekends needs to be improved. Outdoor activities on weekends is an associated factor for myopia among children and adolescents. Particularly, girls, those with myopic parents, schools from urban districts, and spending long hours on homework during weekends among children and adolescents require increased attention.

Objective To analyze the respective abnormal brain regions and commonly altered brain regions of spontaneous brain ac-tivity in post-stroke aphasia(PSA)and post-stroke depression(PSD),and to explore the potential pathological mechanisms underlying single disease and comorbidity.Methods Literatures were retrieved from PubMed,Embase,Web of Science,Cochrane Library,CNKI,Wanfang data,VIP and SinoMed,from establishment to April 19th,2025.Resting-state functional magnetic resonance imaging(fMRI)studies were included if they focused on patients with PSA or PSD,with healthy controls(HC)serving as control group,and amplitude of low-frequency fluctuation(ALFF),fractional amplitude of low-frequency fluctu-ation(fALFF)and regional homogeneity(ReHo)were adopted as outcome indicator.Data regarding differential brain regions were extracted from the original studies,and a neuroimaging meta-analysis was conducted using SDM-PSI V6.23 beta.Results A total of 17 articles on PSA(339 patients and 351 HC)and five articles on PSD(102 patients and 149 HC)were included.The spontaneous brain activity in the left cerebellar area 9,right middle temporal gyrus and right insula was significantly higher in PSA patients than in HC(P<0.05),while activity in the right cerebellar area 6,left medial superior frontal gyrus(SFGmed),left middle frontal gyrus and right anterior cingulate/paracingulate gyrus was lower(P<0.05).For PSD,spontaneous brain activity was elevated in the right cuneus gyrus and right superior occipital gyrus compared to HC(P<0.05),while it was reduced in the left SFGmed and left inferior pa-rietal lobe(P<0.05).Additionally,spontaneous brain activity in the left medial superior frontal gyrus was lower in both diseases compared to HC(P<0.05).Conclusion The pathological mechanism of PSA may involve a pattern of right-sided compensatory hyperfunction and left-sided inhibitory damage within the language-related network,accompanied by cross-hemispheric synergistic activity of the cerebellum.The occurrence of PSD may be attributed to hyperactivity of the right occipital net-work,and functional inhibition involving the left inferior parietal lobe.The inhibition observed in the left SFG-med(MNI coordinates x=0,y=26,z=44)likely represents the language-emotion integration hub,mediating the co-occurrence of PSA and PSD.
