ObjectiveTo investigate the protective effect of genistein (Gen) on etoposide-induced chondrocyte senescence and its underlying mechanism. MethodsThe C28/I2 cell line was treated with different concentrations of Gen and etoposide, and the cell viability was detected by the CCK-8 assay. The senescence model of C28/I2 chondrocytes was induced by etoposide, with Gen intervention. Senescence-associated β-galactosidase (SA-β-gal) staining was performed to detect the senescence-positive rate and staining characteristics of chondrocytes. The expressions of peroxiredoxin 6 (Prdx6), cyclin-dependent kinaseto clarify the functional necessity of Prdx6. ResultsCompared with the etoposide group, the C28/I2 chondrocyte viability significantly increased (P<0.01), the expression ofsenescence-associated proteins p21 and p16 decreased (P<0.01, P<0.05), the expression of senescence-associated genes p21 and p16 reduced (both P<0.01), the fluorescence intensity of senescence-associated proteins p21 and p16 was diminished (P<0.05, P<0.01), and the proportion of SA-β-gal-positive cells decreased (P<0.01) in the Gen+etoposide group. Compared with the Control group, the expression of Prdx6 was downregulated in the etoposide group (P<0.05). Compared with the etoposide group, the expression of Prdx6 was upregulated in the Gen+etoposide group (P<0.01). Compared with the Control group, the GPx activity significantly decreased in the si-Prdx6 group (P<0.01). Furthermore, compared with the si-Prdx6 group, the GPx activity increased in the si-Prdx6+Gen group (P<0.05). Molecular docking results revealed that Gen formed hydrogen bond interactions with the active site of Prdx6. After Prdx6 knockdown, the expression of senescence-associated genes p21 and p16 and the fluorescence intensity of senescence-associated proteins p21 and p16 both increased in the Gen+etoposide+si-Prdx6 group (both P<0.01). ConclusionGen can inhibit etoposide-induced senescence of C28/I2 chondrocytes by upregulating the expression of Prdx6. This study provides potential drug targets and experimental basis for the prevention and treatment of chondrocyte senescence-related diseases.

Objective To investigate the causal relationship between metabolic syndrome and breast cancer by using a bidirectional two-sample Mendelian randomization (MR) approach. Methods Genome-wide association study (GWAS) summary statistics for metabolic syndrome and breast cancer were acquired from the Integrative Epidemiology Unit GWAS database and the GWAS Catalog, with populations encompassing the United States and East Asia. A bidirectional causal design was employed: a forward analysis with metabolic syndrome as the exposure and breast cancer as the outcome, followed by a reverse analysis wherein their roles were interchanged. The inverse-variance weighting (IVW) method was primarily used for effect estimation, supplemented by MR-Egger regression, the weighted median method, the simple mode method, and the weighted mode method. Instrument variable strength was screened using the F-statistic (F>10). Robustness of the results was assessed through heterogeneity tests, horizontal pleiotropy tests, forest plots, and leave-one-out sensitivity analyses. Results The IVW analysis indicated no significant causal relationship between metabolic syndrome and breast cancer (OR=1.00, 95%CI: 0.97-1.03), P>0.05). Sensitivity analyses yielded consistent results, suggesting the good robustness of the study findings. Conclusion This study found no evidence to support a causal relationship, either positive or negative, between metabolic syndrome and breast cancer.

ObjectiveTo investigate the effects and mechanisms of pulchinenoside A (PSA) on tumor necrosis factor-α (TNF-α) -induced abnormal proliferation, migration, and invasion of synovial fibroblasts. MethodsA synovitis model was established by stimulating SW982 synovial cells with TNF-α. The low-density lipoprotein receptor-related protein 1 (LRP1) was knocked down using LRP1-specific siRNA or inhibited by the receptor-associated protein (RAP). Cells were treated with various concentrations of PSA, and cell viability was assessed by CCK-8 assay. Protein levels of LRP1, matrix metalloproteinase-3 (MMP3), and N-cadherin were measured by Western blotting. Proliferation was evaluated using an EdU incorporation assay. Migration and invasion capacities were examined by Transwell and wound-healing assays. mRNA expression of LRP1, MMP3, N-cadherin, IL-1β, IL-6, and TNF-α was detected by reverse transcription quantitative real-time PCR (RT-qPCR). Immunofluorescence staining was used to visualize the expression of MMP3 and N-cadherin. The involvement of LRP1 was further verified with the inhibitor RAP. ResultsCompared with the TNF-α-treated model group, PSA treatment significantly reduced SW982 cell viability (P<0.05), downregulated MMP3 and N-cadherin expression (both P<0.01), and decreased the proportion of EdU-positive cells (P<0.05). Moreover, TNF-α stimulation upregulated LRP1 expression compared with normal controls (P<0.01), whereas PSA treatment reversed this increase (P<0.05). LRP1 knockdown or inhibition markedly decreased MMP3 and N-cadherin levels compared with the model group (both P<0.01). Similarly, the combination of PSA and RAP led to significant reductions in MMP3 and N-cadherin expression compared with the model group (both P<0.01). ConclusionPSA inhibits TNF-α-induced abnormal proliferation, migration, and invasion of synovial, at least in part, by downregulating LRP1 expression.
5.Policy analysis of family-school-society collaboration mechanisms for promoting students physical and mental health
Chinese Journal of School Health 2026;47(9):1240-1245
Objective:
To analyze the text structure, temporal evolution, and mechanism related shortcomings of policies related to family-school-society collaboration in promoting students physical and mental health in China, thereby providing a reference for improving collaborative mechanisms in the context of health promoting school development.
Methods:
The PKULAW Laws and Regulations Database was used as the data source. A total of 115 relevant policy documents issued by relevant departments from the founding of the People s Republic of China to May 7, 2026, were included. Drawing on the adolescent health policy analysis framework and adapting it to the Chinese contexts of family-school-society collaborative education, health promoting school development, and interdepartmental collaborative governance, policy text analysis was conducted. Multi label coding was applied to 629 semantic units, and fractional counting was used to calculate the weights of 6 main dimensions and 31 subdimensions and to describe the dimensional composition of the policies and its changes over time.
Results:
Policies related to family-school-society collaboration in promoting students physical and mental health gradually evolved from early principle based collaboration centered on the ideological and moral development of minors into institutional arrangements supported by the Healthy China initiative, the legal institutionalization of family education, collaborative education mechanisms, and health promoting school development. Among the 6 main dimensions, policy features and costs accounted for 54.8% of the total weight, followed by implementation considerations (22.9%), monitoring and evaluation (9.5%), policy appropriateness (5.6%), inclusion and coverage (4.8%), and participatory approach (2.5%). At the subdimension level, proposed interventions, target population characteristics, intersectoral linkages, consideration of adolescents social ecology, and goal setting accounted for 18.7%, 16.0%, 12.0%, 9.6%, and 9.4% of the total weight, respectively, whereas adolescent participation and the incorporation of young people s voices accounted for only 0.3% and 0.1% , respectively. These findings indicated that the policy texts focused primarily on problem identification, target population specification, and implementation arrangements, while provisions concerning students active participation, identification of differentiated needs, and support from disaggregated data remained relatively limited.
Conclusions
China has established a policy framework for family-school-society collaboration in promoting students physical and mental health that emphasizes goal setting, responsibility division, and organizational implementation, while gradually extending to specific health promotion tasks. Nevertheless, policy provisions concerning students active participation, the identification of differentiated needs, stratified and category specific monitoring, and the use of evaluation feedback require further specification.

Shengyutang is a famous classical formula of tonic, which is made from Siwutang with Ginseng Radix et Rhizoma and Astragali Radix. It is included in the Catalogue of Ancient Famous Classical Formulas(The First Batch). Based on the Principles of Key Information Research of Ancient Famous Classical Formulas, this paper used bibliometrics to sort out and research the key information of Shengyutang in the aspects of history, composition, origin and processing, dosage, decocting method, efficacy and indications. After research, it has been found that this formula was first recorded in Lanshi Micang written by LI Dongyuan during the Jin dynasty, composed of Rehmanniae Radix, Rehmanniae Radix Praeparata, Chuanxiong Rhizoma, Ginseng Radix et Rhizoma, Astragali Radix and Angelicae Sinensis taproot. The name of the formula passed down through generations was relatively unified, with clear origins and veins. In later generations, this formula was the mainstream, and adjustments were made to the dosage and composition according to the indication. In the formula, Astragalus membranaceus var. mongholicus was selected as the origin of Astragali Radix, and the origins of other medicinal materials were consistent with the 2020 edition of Chinese Pharmacopoeia. Except for Rehmanniae Radix Praeparata, the other medicinal materials were made from raw products, and the dosage form was boiled powder. According to the measurement standard in the Jin dynasty, the recommended usage and dosage were 1.24 g of Rehmanniae Radix, Rehmanniae Radix Praeparata, Chuanxiong Rhizoma, Ginseng Radix et Rhizoma each, 2.07 g of Astragali Radix and Angelicae Sinensis taproot each, crushed into coarse particles that pass through the 4 mesh sieve but can't pass through the 10 mesh sieve, added 1 200 mL of water and boiled to 300 mL, and removed the residue. Shengyutang has the functions of tonifying Qi and blood, and blood intake, treating various sores, and restlessness and insomnia caused by excessive blood flow. In ancient times, this formula was widely used in the treatment of surgical sores, gynecological diseases, deficiency syndrome, etc. In modern clinical practice, it is mostly used to treat gynecological, neurological, musculoskeletal, hematological diseases caused by Qi and blood deficiency. In this paper, the key information of Shengyutang was researched by reviewing relevant ancient literature, in order to provide reference for the modern application and development of this formula.

Idiopathic pulmonary fibrosis (IPF), a chronic interstitial lung disease, is characterized by aberrant wound healing, excessive scarring and the formation of myofibroblastic foci. Although the role of alternative splicing (AS) in the pathogenesis of organ fibrosis has garnered increasing attention, its specific contribution to pulmonary fibrosis remains incompletely understood. In this study, we identified an up-regulation of serine/arginine-rich splicing factor 7 (SRSF7) in lung fibroblasts derived from IPF patients and a bleomycin (BLM)-induced mouse model, and further characterized its functional role in both human fetal lung fibroblasts and mice. We demonstrated that enhanced expression of Srsf7 in mice spontaneously induced alveolar collagen accumulation. Mechanistically, we investigated alternative splicing events and revealed that SRSF7 modulates the alternative splicing of pyruvate kinase (PKM), leading to metabolic dysregulation and fibroblast activation. In vivo studies showed that fibroblast-specific knockout of Srsf7 in conditional knockout mice conferred resistance to bleomycin-induced pulmonary fibrosis. Importantly, through drug screening, we identified lomitapide as a novel modulator of SRSF7, which effectively mitigated experimental pulmonary fibrosis. Collectively, our findings elucidate a molecular pathway by which SRSF7 drives fibroblast metabolic dysregulation and propose a potential therapeutic strategy for pulmonary fibrosis.

Microbial communities such as those residing in the human gut are highly diverse and complex, and many with important implications for health and diseases. The effects and functions of these microbial communities are determined not only by their species compositions and diversities but also by the dynamic intra- and inter-cellular states at the transcriptional level. Powerful and scalable technologies capable of acquiring single-microbe-resolution RNA sequencing information in order to achieve a comprehensive understanding of complex microbial communities together with their hosts are therefore utterly needed. Here we report the development and utilization of a droplet-based smRNA-seq (single-microbe RNA sequencing) method capable of identifying large species varieties in human samples, which we name smRandom-seq2. Together with a triple-module computational pipeline designed for the bacteria and bacteriophage sequencing data by smRandom-seq2 in four human gut samples, we established a single-cell level bacterial transcriptional landscape of human gut microbiome, which included 29,742 single microbes and 329 unique species. Distinct adaptive response states among species in Prevotella and Roseburia genera and intrinsic adaptive strategy heterogeneity in Phascolarctobacterium succinatutens were uncovered. Additionally, we identified hundreds of novel host-phage transcriptional activity associations in the human gut microbiome. Our results indicated that smRandom-seq2 is a high-throughput and high-resolution smRNA-seq technique that is highly adaptable to complex microbial communities in real-world situations and promises new perspectives in the understanding of human microbiomes.

Stresses induced by the deficiency or excess of trace mineral elements, such as manganese (Mn), represent a common limiting factor for the production of crops like Brassica napus. To identify key genes involved in Mn allocation in B. napus and elucidate the underlying mechanisms, a member of the metal tolerance protein (MTP) family obtained in the previous screening of cDNA library of B. napus under Mn stress was selected as the research subject. Based on the sequence information and phylogenetic analysis, it was named as BnMTP10. It belongs to the Mn-cation diffusion facilitator (CDF) subfamily. Expression of BnMTP10 in yeast significantly improved the tolerance of transformants to excessive Mn and iron (Fe) and reduced the accumulation of Mn and Fe. However, the yeast transformants exhibited no significant changes in tolerance to excess cadmium, boron, aluminum, zinc, or copper. The qRT-PCR results demonstrated that the flowers of B. napus had the highest expression of BnMTP10, followed by roots and leaves. Subcellular localization studies revealed that BnMTP10 was localized in the endoplasmic reticulum (ER). Compared with wild-type plants, transgenic Arabidopsis overexpressing BnMTP10 exhibited enhanced tolerance to excessive Mn stress but showed no significant difference under Fe stress. Correspondingly, under excessive Mn stress, the Mn content in the roots of transgenic Arabidopsis increased significantly. However, under excessive Fe stress, the Fe content in transgenic Arabidopsis did not alter significantly. According to the results, we hypothesize that BnMTP10 may alleviate excessive Mn stress in plants by mediating Mn transport to the ER. This study facilitated our understanding of efficient mineral nutrients, and provided theoretical foundations and gene resources for breeding B. napus.

Objective To analyze the disease burden of early-onset colorectal cancer (EOCRC) at the global, regional, and national levels from 1990 to 2021, and to predict the disease burden trend from 2022 to 2026. Methods Based on the Global Burden of Disease (GBD) database, the incidence, mortality, and disability-adjusted life year (DALY) rate of EOCRC across 204 countries and regions from 1990 to 2021 were obtained. The time trends of these indicators were assessed by calculating the estimated annual percentage change (EAPC), and the contributions of ten risk factors to the EOCRC burden were analyzed. The autoregressive integrated moving average (ARIMA) model was used to predict the disease burden from 2022 to 2026. Results From 1990 to 2021, the number of new global EOCRC cases increased from 107 310 to 211 890, with the incidence rising from 3.96 to 5.37 per 100 000 people. In 2021, global EOCRC incidence, mortality, and DALY rate increased with age; males had higher rates than females in terms of incidence, mortality, and DALY rate in all age groups. In 2021, East Asia had the highest number of new cases, deaths, and DALY. From 1990 to 2021, the global EAPC for incidence rate was 0.96%, and death rate was –0.38%. ARIMA model indicated that from 2022 to 2026, the global incidence of EOCRC would continue to rise, while mortality and DALY rate would be expected to decline. Conclusions The disease burden of EOCRC has significantly increased globally from 1990 to 2021, with notable regional, age, and sex differences. By 2026, the mortality and DALY rate of EOCRC will decline, while the incidence is expected to further increase, highlighting the urgency of taking active measures to address the growing trend of EOCRC.
