Objective:
To explore the associations of moderate to vigorous intensity physical activity (MVPA) and sedentary behavior (SB) among primary and secondary school students and their parents, so as to provide a scientific basis for formulating targeted physical activity promotion strategies for children and adolescents.
Methods:
From 2021 to 2022, basic information and 24 h movement behaviors of 2 484 pairs of students and their parents were collected from five primary and secondary schools in Haizhu District, Guangzhou City, with a convenient sampling combining with cluster sampling method. Component regression models were constructed to analyze the relationship between parental MVPA, SB and primary and secondary school students MVPA and SB, and a component isochronous substitution model was used to explore the effects of mutual substitution between parental MVPA, residual components (time use components other than SB during the 24 h period), and SB on the behavioral activities of MVPA and SB in primary and secondary school students.
Results:
Parental MVPA and SB of students in grade 1 to 3 were positively correlated with both students MVPA and SB ( β=0.06, 0.12, P <0.01). The component isochronous substitution model showed that substituting 10 and 20 minutes of MVPA for SB by parents in grade 1 to 3 was associated with an increase in MVPA of students, and substituting 10 and 20 minutes of residual ingredients for SB was associated with a decrease in SB of students, with mean changes of 0.8 (95% CI =0.4-1.2) and 1.4 (95% CI =0.7-2.2) and -1.4 (95% CI =-1.7 to -1.1) and -2.9 (95% CI =-3.4 to -2.3)( P <0.05). No statistically significant associations were observed between parents of students in grades 4 to 6 and 7 to 9 and students physical activity and sedentary behaviour ( P >0.05).
Conclusions
Parents of students in grades 1 to 3 increases MVPA and decrease SB are beneficial to increase MVPA and decrease SB of students. Parents could promote physical activity among primary and secondary school students, and the intervention gateway should be advanced, with the low grades as the optimal intervention period.

Posterior capsule opacification(PCO)is a common postoperative complication of cataract surgery, primarily caused by the proliferation and migration of residual lens epithelial cells(LECs). Although neodymium-doped yttrium aluminum garnet(Nd:YAG)laser posterior capsulotomy effectively treats PCO, it carries risks of complications such as cystoid macular edema(CME). Thus, preventing PCO formation is of critical clinical importance. Despite advancements in intraocular lens(IOL)materials and designs, achieving complete PCO eradication remains challenging. This review systematically examines recent advancements in surface-modified IOLs, including anti-biofouling IOL(reducing LECs adhesion), capsular adhesion-enhanced IOL(promoting capsular bag integration), micro-patterned IOL(physically inhibiting migration), photothermal/photodynamic IOL(inducing light-activated LECs apoptosis), and drug-eluting IOL(sustained drug release). These surface modification strategies demonstrate synergistic effects through complementary mechanisms(including physical barrier formation, chemical intervention, and bioactive regulation), effectively suppressing LECs proliferation while significantly reducing PCO incidence. Importantly, these approaches eliminate the risks associated with conventional Nd:YAG laser treatment, offering substantial advantages. By providing a comprehensive evaluation of these cutting-edge technologies, this review serves as a valuable reference for IOL design optimization. It represents a paradigm shift in cataract management strategies, transitioning from reactive therapeutic interventions to proactive preventive measures, and ultimately leads to improving long-term visual outcomes for patients.

Due to the wide variety and varying quality of medical wound dressings, as well as the current lack of unified national or industry standards for regulation, this paper proposes a research strategy for establishing a quality evaluation system for medical wound dressings. By developing a technical roadmap, this strategy clarifies the process flow and key points in the quality evaluation process, establishes evaluation methods for various types of medical wound dressings, and addresses important issues such as how to determine key performance indicators based on product characteristics and how to research and validate test methods for key items. This provides a detailed and feasible research strategy and evaluation method for medical wound dressing manufacturers, testing institutions, and regulatory authorities. It reduces the difficulty and cost of quality evaluation for medical wound dressings and has certain significance in standardizing and improving their quality level, ensuring their safety and effectiveness, and serving the quality and safety regulation of medical devices..

6.Causal effect of sleep disorders on the risk of cerebrovascular events and complications: A two-sample Mendelian randomization study
Journal of Apoplexy and Nervous Diseases 2025;42(10):890-900
Objective To investigate the causal association between sleep disorder-related phenotypes and cerebrovascular outcomes/complications using the two-sample Mendelian randomization (MR) method, and to determine causal orientation via directionality testing. Methods Genetic variations from genome-wide association studies were used as instrumental variables to analyze eight sleep-related phenotypes (continuous sleep, snoring, napping, insomnia, morning diurnal preference, daytime sleepiness, long sleep, and short sleep) against multiple cerebrovascular outcomes and complications (cerebral infarction, unruptured cerebral artery dissection, cerebral arteritis, cerebral amyloid angiopathy, unruptured cerebral aneurysm, cerebral atherosclerosis, intracerebral hemorrhage, vascular syndrome, and sequelae of cerebrovascular disease). The inverse-variance weighted (IVW) method was used for primary analysis, with the assistance of the sensitivity methods such as MR-Egger, weighted median, simple mode, and weighted mode, and the Estimate value was used to characterized effect direction and magnitude, with statistical significance assessed by P value. The Steiger directionality test was used to compare the extent of variance explained by instrumental variables concerning exposure and outcome and confirm causal direction. Results The IVW analysis showed that snoring was associated with an increased risk of cerebral amyloid angiopathy (Estimate=8.08, 95% CI 1.93-14.23, P=0.01), and long sleep duration was associated with an increased risk of cerebral atherosclerosis (Estimate=14.95, 95% CI 2.44-27.46, P=0.02). Short sleep duration was associated with an increased risk of cerebral arteritis (Estimate=13.33, 95% CI 1.54-25.12, P=0.03); however, inconsistent directions were observed across sensitivity methods (e.g., MR-Egger), and therefore, it was treated as suggestive evidence rather than a robust conclusion. The Steiger test showed R2exposure>R2outcome for most exposure-outcome pairs, and the key associations did not persist under reverse-direction analyses, supporting a forward causal pathway from sleep phenotypes to cerebrovascular outcomes and reducing the likelihood of reverse causation. Conclusion Genetic evidence supports a forward causal effect of sleep-related phenotypes on cerebrovascular outcomes and complications, with the most robust findings of “snoring increases the risk of cerebral amyloid angiopathy” and “long sleep duration increases the risk of cerebral atherosclerosis”. Identification and treatment of sleep-disordered breathing and avoidance of prolonged sleep may be used as potential targets for preventing cerebrovascular disease, and multi-ethnic prospective studies and interventional trials are needed to further validate these findings and clarify the underlying biological mechanisms.
