Animal experimentation constitutes a critical link between basic research and clinical application, making its research quality and translational efficiency paramount. Although considerable progress has been made in standardizing operational procedures and ethical guidelines, the standardization of outcome evaluation systems has significantly lagged, creating a key bottleneck that constrains the quality of biomedical research and evidence synthesis. This deficiency is manifested by pronounced heterogeneity in outcome selection across similar studies, incomplete methodological reporting, and disparate criteria for result interpretation, which severely impairs the comparability of findings and the evidence integration. To cope with this challenge, this paper systematically introduces a mature methodological tool from clinical research–the core outcome set (COS)–and explores its construction strategies and application potential in the field of animal experimentation. Given the extensive diversity of animal experiments, a pragmatic strategy of "focusing on key areas, implementing phased pilots, and promoting gradual expansion" should be adopted. This approach prioritizes the development of domain-specific COS for disease areas characterized by high research volume, urgent translational needs, and well-established animal models. A multi-source integration pathway for COS development is detailed, comprising systematic literature searches, methodological appraisals, and expert consensus, with the feasibility of leveraging artificial intelligence (AI) to enhance efficiency also being examined. The development and promotion of such COS are not intended to restrict scientific exploration; rather, they aim to establish a new, tiered evaluation paradigm consisting of "core outcomes" (mandatory), "recommended outcomes" (encouraged), and "exploratory outcomes" (optional). This framework is expected not only to enhance research quality through standardization and to adhere to the "3R" principles but also to accelerate the accumulation of high-quality evidence. This, in turn, provides a solid foundation for higher-level evidence synthesis, ultimately facilitating the effective translation of basic research findings into clinical practice and providing an essential methodological framework for scientific advancement in relevant disciplines.

Objective: To examine the association between school sports environment and exercise habits among college students, and to test the mediating role of weight management intention in the relationship, so as to provide empirical evidence for promoting exercise habit formation of college students. Methods: A multi stage cluster sampling survey was conducted from April 15 to May 15, 2025, among 2 687 undergraduates from 8 colleges in Beijing, Shandong, Henan, Shanxi and Guangxi Zhuang Autonomous Region in China. School Sports Environment Characteristics Questionnaire, Weight Management Behavioral Intention Questionnaire and College Students Exercise Habit Scale were used for evaluation. Pearson correlation analysis was applied to examine the correlations among the three variables. A structural equation model (SEM) was constructed using AMOS 26.0, and the mediating effect was tested using the Bootstrap method. Results: The score for school sports environment was (3.72±0.57), with scores of (3.68±0.61) for physical environment and (3.74±0.59) for social environment; the scores for weight management intention and the total exercise habit were (4.21±0.46) and (3.94±0.51). School sports environment was positively correlated with weight management intention ( r =0.56) and exercise habits ( r =0.57), and weight management intention was positively correlated with exercise habits ( r =0.71) (all P <0.01). The SEM showed that school sports environment exerted positive impact on weight management intention ( β =0.50) and exercise habits ( β =0.29), weight management intention had a significant positive path to exercise habits ( β =0.52) (all P <0.01). Weight management intention of college students played a partial mediating role in the association between school sports environment and exercise habits, with an indirect effect of 0.259, accounting for 47.01% of the total effect. Conclusions The school sports environment is positively correlated with college students exercise habits, and might indirectly facilitate habit cultivation by improving weight management intention. While optimizing the physical and social environments of school sports in colleges, colleges should place a strong emphasis on stimulating college students weight management intention to promote the formation of their exercise habits.

Aim To investigate the predictive value of lipoprotein(a)[Lp(a)]combined with systemic inflam-matory response index(SIRI)on in-stent restenosis(ISR)after percutaneous coronary intervention(PCI)in patients with coronary heart disease.Methods The clinical data of 770 patients with coronary heart disease who underwent PCI in the Department of Cardiovascular Medicine of the First Affiliated Hospital of Xinjiang Medical University from May 2012 to December 2024 and underwent coronary angiography six months after surgery were collected.According to the imaging re-sults,the patients were divided into ISR group(n=194)and non-ISR group(n=576).Multivariate Logistic regression and random forest model were used to analyze the independent risk factors of ISR.Risk factors included in the analysis were glycated hemoglobin,SIRI,Lp(a),lymphocyte count,apolipoprotein A1(ApoA1)and residual cholesterol.Results The levels of Lp(a)and SIRI in the ISR group were significantly higher than those in the non-ISR group(P＜0.05).ROC curve analysis showed that the area under the curve of the combined indicator of Lp(a)and SIRI was 0.789,which was higher than the 0.652 of the single indicator Lp(a)and 0.778 of SIRI.Conclusion Lp(a)and SIRI are independent risk factors for the occurrence of ISR after PCI,and the combination of Lp(a)and SIRI can better predict the occurrence of ISR.

Objective:To develop a quality assessment index system for infection prevention and control in integrated medical and elderly care facilities, providing methods for assessing infection control quality and a theoretical basis for enhancing infection prevention and control capabilities.Methods:This study initially constructed a framework for the quality evaluation index system through literature reviews, work specifications and standards and expert interviews. The Delphi method was employed to conduct two rounds of consultations with 19 experts to evaluate the necessity, feasibility, stability, and sensitivity of the indicators. The expert′s active coefficient, authority coefficient, degree of consensus, and coordination were statistically analyzed. The indicators were revised based on expert opinions to finalize the evaluation index system. The weights of the evaluation dimensions were determined using the Analytic Hierarchy Process (AHP), while the weights of the indicators were determined using the proportional allocation method. Reliability was assessed via Cronbach′s α coefficient, and content validity was verified through the Content Validity Index ( CVI). Results:After two rounds of expert consultation, the expert positive coefficient, expert authority coefficient ( Cr) and expert coordination coefficient Kendall′s W was 100%, 0.992 and 0.634 ( P<0.001), indicating high expert authority, good concentration and coordination of opinions. The assessment index system for infection prevention and control quality in integrated medical and elderly care facilities was ultimately constructed, comprising three primary indicators, 18 secondary indicators and 68 tertiary indicators. Among the primary indicators, the process quality had the highest weight of 0.338. Within the process quality, the secondary indicators with the highest weights were infection control material allocation, hand hygiene quality and the management of cluster outbreaks. A total of 11 unique evaluation indicators for integrated medical and elderly care facilities were established, with the highest weighted indicator being the rate of standardized surveillance of infection-related risk factors. Reliability and validity analyses demonstrated that the overall Cronbach′s α coefficient of the system was 0.991, and the Scale-level Content Validity Index was 0.936, confirming good reliability and validity. Conclusion:The evaluation index system constructed in this study can serve as an effective assessment tool for the quantitative evaluation of infection control quality in integrated medical and elderly care facilities. Furthermore, it is recommended that the system undergo continuous optimization concerning its application.

Extracellular vesicles(EVs)are small vesicles secreted by cells,widely present in various body fluids,and they play important biological roles.In recent years,EVs have garnered significant attention as novel diagnostic and thera-peutic tools in multiple ocular diseases.Glaucoma,as a common cause of irreversible blindness,is primarily caused by optic nerve damage associated with pathologically elevated intraocular pressure.Emerging evidence indicates that EVs hold considerable therapeutic potential in glaucoma management,particularly in modulating aqueous humor circulation and pro-viding retinal neuroprotection.This review summarizes the latest research progress on EVs in the treatment of glaucoma.

OBJECTIVES: Osteoarthritis (OA) is one of the most common chronic degenerative diseases, with chondrocyte apoptosis and extracellular matrix (ECM) degradation as the major pathological changes. The mechanical stimulation can attenuate chondrocyte apoptosis and promote ECM synthesis, but the underlying molecular mechanisms remain unclear. This study aims to investigate the role of primary cilia (PC) in mediating the effects of mechanical stimulation on OA progression. METHODS: In vivo, conditional knockout mice lacking intraflagellar transport 88 (IFT88^flox/flox IFT88 knockout; i.e., primary cilia-deficient mice) were generated, with wild-type mice as controls. OA models were established via anterior cruciate ligament transection combined with destabilization of the medial meniscus, followed by treadmill exercise intervention. OA progression was evaluated by hematoxylin-eosin staining, safranin O-fast green staining, and immunohistochemistry; apoptosis was assessed by TUNEL staining; and limb function by rotarod testing. In vitro, primary articular chondrocytes were isolated from mice and transfected with lentiviral vectors to suppress IFT88 expression, thereby constructing a primary cilia-deficient cell model. Interleukin-1β (IL-1β) was used to induce an inflammatory environment, while cyclic tensile strain (CTS) was applied via a cell stretcher to mimic mechanical loading on chondrocytes. Immunofluorescence and Western blotting were used to detect the protein expression levels of type II collagen α1 chain (COL2A1), primary cilia, IFT88, and caspase-12; reverse transcription polymerase chain reaction was performed to assess COL2A1 mRNA levels; and flow cytometry was used to evaluate apoptosis. RESULTS: In vivo, treadmill exercise significantly reduced Osteoarthritis Research Society International (OARSI) scores and apoptotic cell rates, and improved balance ability in wild-type OA mice, whereas IFT88-deficient OA mice showed no significant improvement. In vitro, CTS inhibited IL-1β-induced ECM degradation and apoptosis in primary chondrocytes; however, this protective effect was abolished in cells with suppressed primary cilia expression. CONCLUSIONS Mechanical stimulation delays OA progression by mediating signal transduction through primary cilia, thereby inhibiting cartilage degeneration and chondrocyte apoptosis.

Objective: To analyze the correlation of physical activity and screen time with anxiety and depressive symptoms among college students, so as to provide a reference for formulating intervention measures for anxiety and depressive symptoms among college students. Methods: In May 2024, the method of combining convenient sampling with stratified sampling was adopted to select 3 076 college students from 5 colleges in Shaoxing of Zhejiang Province. Self compiled general situation questionnaires, Screen Time Questionnaire, Selfrating Anxiety Scale and Self rating Depression Scale were used to investigate the current status of college students physical activities, screen time, anxiety and depressive symptoms, etc. Inter group comparisons were conducted by using the χ 2 test, Fisher s exact probability test, t-test or analysis of variance. A multivariate Logistic regression model was established to explore the correlations between physical activity, screen time with anxiety and depressive symptoms among college students. Results: The constituent ratios of mild, moderate and severe anxiety symptoms were 59.97%, 28.99% and 11.04%, respectively. The constituent ratios of mild, moderate and severe depressive symptoms were 64.96%, 29.92% and 5.12%, respectively. There were statistically significant differences in the detection rates of anxiety symptom ( χ 2=15.99) and depressive symptom ( χ 2=16.54) among college students of different grades and screen time daily (both P <0.05). There were statistically significant differences in physical activity among college students of different genders and subject types ( t/F =11.67, 11.90, both P <0.01). Multivariate Logistic regression analysis showed that when physical activity was at least 1 hour per week <3 d, a screen time <2 h/d could reduce the risk of anxiety symptoms among college students ( OR =0.57), and screen time <2, 2-<3, 3-<4 h/d could reduce the risk of depressive symptoms among college students ( OR =0.65, 0.56, 0.64); when the number of days of physical activity exercise was at least 1 h per week ≥3 d, the occurrence risks of anxiety symptom( OR =0.49, 0.58) and depressive symptom ( OR =0.36, 0.43) were reduced for students with screen time <2 and 2-<3 h/d (all P <0.05). Conclusions There are correlations of physical activity and screen time with anxiety and depressive symptoms among college students. Low physical activity and longer screen time are more likely to increase the risk of anxiety and depressive symptom among college students.

Jansen-de Vries syndrome, also known as intellectual developmental disorder with gastrointestinal difficulties and high pain threshold, is a rare autosomal dominant disorder characterized by multisystem involvement. This article reports the case of a young child who presented with global developmental delay, gastrointestinal dysfunction, intellectual disability, and short stature. Distinct facial features included a broad forehead, low nasal bridge, thin upper lip, and widely spaced and misaligned teeth. Additional phenotypic findings involved small hands and feet, as well as digital anomalies. Through whole-exome sequencing (WES) and copy number variation (CNV) analysis, a pathogenic variant was identified in the PPM1D gene: c.1281G > A (p.Trp427Ter). This report also reviews the current literature on the clinical characteristics, diagnostic approaches, and therapeutic advances related to this condition, aiming to provide valuable insights for its clinical diagnosis and management.

BACKGROUND: The American Heart Association (AHA) introduced the concept of cardiovascular-kidney-metabolic (CKM) health and stage, reflecting the interaction among metabolism, chronic kidney disease (CKD), and the cardiovascular system. However, the association between CKM stage and the long-term risk of cardiovascular disease (CVD) has not been validated. This study aimed to evaluate the long-term CVD risk associated with CKM health metrics and CKM stage using data from a population-based cohort study. METHODS: In total, 5293 CVD-free participants were followed up to around 13 years in the Chinese Multi-provincial Cohort Study (CMCS). Considering the pathophysiologic progression of CKM health metrics abnormalities (comprising obesity, central adiposity, prediabetes, diabetes, hypertriglyceridemia, CKD, and metabolic syndrome), participants were divided into CKM stages 0, 1, and 2. The time-dependent Cox regression models were used to estimate the cardiovascular risk associated with CKM health metrics and stage. Additionally, broader CVD outcomes were examined, with a specific assessment of the impact of stage 3 in 2581 participants from the CMCS-Beijing subcohort. RESULTS: Among participants, 91.2% (4825/5293) had at least one abnormal CKM health metric, 8.8% (468/5293), 13.3% (704/5293), and 77.9% (4121/5293) were in CKM stages 0, 1, and 2, respectively; and 710 incident CVD cases occurred during a median follow-up time of 13.3 years (interquartile range: 12.1 to 13.6 years). Participants with each poor CKM health metric exhibited significantly higher CVD risk. Compared with stage 0, the hazard ratio (HR) (95% confidence interval [CI]) for CVD incidence was 1.31 (0.84-2.04) in stage 1 and 2.27 (1.57-3.28) in stage 2. Significant interactive impacts existed between CKM stage and age or sex, with higher CVD risk related to increased CKM stages in participants aged <60 years or females. CONCLUSION These findings highlight the contribution of CKM health metrics and CKM stage to the long-term risk of CVD, suggesting the importance of multi-component recognition and management of poor CKM health in CVD prevention.
