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.‌.

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.

Objective To investigate the expression of serum microRNA-29b(miR-29b),microRNA-199a(miR-199a),and microRNA-19a-3p(miR-19a-3p)in patients with acute cerebral infarction(ACI)and their relationship with disease severity and prognosis.Methods(1)Rats were randomly divided into a control group(Control group)and a model group(Model group),with 6 rats in each group.ACI was induced in the model group using the modified Longa suture method;the expression levels of miR-29b,miR-199a,miR-19a-3p in rat serum and brain tissue were detected and analyzed.(2)A total of 106 ACI patients diagnosed at Tangshan People's Hospital from June 2023 to June 2024 were enrolled as the study group,and 108 healthy individuals who underwent physical check-ups at the same hospital during the same period were chosen as the control group.According to the NIHSS evaluation results,the study group patients were assigned into mild(42 cases),moderate(34 cases),and severe(30 cases)groups.Based on the mRS evaluation results,the patients were assigned into good prognosis(68 cases)and poor prognosis(38 cases)groups.Real-time fluorescence quantitative PCR was applied to measure the expression levels of serum miR-29b,miR-199a,and miR-19a-3p.Pearson correlation analyzed the correlation between serum miR-29b,miR-199a,miR-19a-3p levels and NIHSS score and mRS score in ACI patients.The risk factors for poor prognosis in ACI patients were analyzed using multivariate logistic regression.ROC curves were used to analyze the predictive value of serum miR-29b,miR-199a,miR-19a-3p levels and NHISS scores in poor prognosis of ACI patients.Results(1)Compared with the Control group,the levels of miR-199a and miR-19a-3p in the serum and brain tissue of the Model group rats were significantly increased,while the level of miR-29b was significantly decreased(P<0.05);(2)Compared with the control group,as the severity of ACI patients gradually increased,the levels of serum miR-199a and miR-19a-3p unusually increased in the mild,moderate,and severe groups,while the level of miR-29b was significantly decreased(P<0.05).The NHISS score,miR-199a and miR-19a-3p levels in the poor prognosis group were significantly higher than those in the good prognosis group,while miR-29b was significantly lower than that in the good prognosis group(P<0.05).The levels of serum miR-199a and miR-19a-3p were positively correlated with NIHSS score;the level of miR-29b was negatively correlated with NIHSS score(P<0.05).Elevated serum miR-199a and miR-19a-3p levels and increased NHISS score were independent risk factors for poor prognosis in ACI patients,and elevated serum miR-29b levels were protective factors for poor prognosis in ACI patients(P<0.05).The combined prediction of poor prognosis in ACI patients using serum miR-29b,miR-199a,miR-19a-3p levels and NHISS scores yielded an ACI of 0.988,which was superior to individual predictions(Z=2.878,3.551,3.300,3.452,P<0.05).Conclusion The serum expression levels of miR-199a and miR-19a-3p were significantly up-regulated,while miR-29b levels significantly down-regulated,which were related to the disease severity and prognosis.The the combination of the three miRNAs had certain value in predicting the poor prognosis of patients.MiR-29b,miR-199a,and miR-19a-3p can be used as important predictors to evaluate the progression and prognosis of ACI patients.

AIM: To observe the efficacy of phacoemulsification combined with capsular tension ring and intraocular lens implantation in the treatment of high myopia with cataract.METHODS: Retrospective study. A total of 82 cases(82 eyes)of high myopia complicated with cataract who admitted to the cataract department of our hospital from December 2021 to April 2023 were selected as study objects, and they were divided into control group(n=39)and combination group(n=43)according to whether or not the capsular tension ring was used intraoperatively. Patients in the control group were treated with intraocular lens implantation alone, and those in the combination group were treated with phacoemulsification combined with capsular tension ring and intraocular lens implantation. The preoperative and postoperative best corrected visual acuity, central anterior chamber depth, trabecular ciliary process, visual quality and complications were compared.RESULTS: At 1 mo after surgery, the best corrected visual acuity(LogMAR)of both groups increased significantly(combination group: 0.64±0.28 vs 0.12±0.14; control group: 0.62±0.26 vs 0.23±0.25, both P<0.001). Central anterior chamber depth in both groups were higher than those before surgery(combination group: 2.57±0.56 vs 1.97±0.40 mm; control group: 2.22±0.45 vs 1.89±0.37 mm; both P<0.001), and the best corrected visual acuity and central anterior chamber depth of the combination group were significantly better than those of the control group(both P<0.05). The distance of trabecular ciliary process showed no statistical significance(combination group: 0.68±0.22 vs 0.74±0.20 mm; control group: 0.74±0.19 vs 0.78±0.17 mm, both P>0.05). The visual quality scores of the combination group were all higher than the control group at 1 mo after surgery [watching TV: 3.00±0.38 vs 2.22±0.46 points; reading books: 2.85±0.42 vs 2.21±0.44 points; night vision: 2.71±0.34 vs 2.37±0.41 points; fine operation: 2.82±0.38 vs 2.33±0.40 points, all P<0.001]. The incidence of complication in the combination group was significantly lower than that of the control group(33% vs 14%, P<0.05).CONCLUSION: Phacoemulsification combined with capsular tension ring and intraocular lens implantation can effectively promote the recovery of visual function, improve the structure of chamber angle, and reduce the incidence of complications in the treatment of patients with high myopia and cataract.

Objective To investigate the stability of pouch in patients with high myopia cataract after phacoemulsification cataract extraction combined with capsular tension ring(CTR)implantation.Methods A total of 80 patients with high myopia complicated with cataract(80 eyes)were included and randomly divided into the experimental group and the control group.The experimental group received phacoemulsification cataract extraction combined with CTR implantation,while the control group was not combined with CTR implantation,and the other interventions were completely consistent.The naked eye visual acuity(UCVA),best corrected distant visual acuity(BCVA),corneal biomechanics,contrast sensitivity,intraocular lens inclination and anterior capsular opening area were compared between the two groups at 1,3 and 6 months after surgery.The incidence of late cataract(PCO)was measured 6 months after surgery.Results UCVA and BCVA were improved at 1,3 and 6 months after operation.There were no significant differences in postoperative corneal biomechanical parameters ARTh and SP-A between the two groups of patients(P＞0.05).The Corvis biomechanical index(CBI)of the experimental group was significantly higher 3 months after surgery than that of the control group(P＜0.05),and there were no significant differences at other time points between the 2 groups.There was no significant difference in contrast sensitivity at each time point after surgery between the experimental group and the control group(P＞0.05).At 3 and 6 months after operation,the anterior capsule opening area was increased in the experimental group,and IOL inclination angle was decreased compared with the control group(P＜0.05).At 6 months after operation,no PCO occurred in 38 eyes and PCO grade Ⅰ in 2 eyes.No PCO occurred in 35 eyes in the control group,3 eyes in grade Ⅰ,2 eyes in grade Ⅱ and 2 eyes in grade Ⅲ.Conclusion Phacoemulsification cataract extraction combined with CTR implantation has higher stability,long-term clinical effect and visual quality in patients with high myopia cataract,and is worthy of clinical application.

AIM: To evaluate the effect of capsular tension ring(CTR)on the stability and accuracy of Barrett universal Ⅱ intraocular lens(IOL)calculation formula in patients with high myopia and cataract.METHODS:Prospective study. A total of 40 cases(80 eyes)of high myopia and cataract that visited our hospital from January to June 2022 were selected. The patients were divided into CTR group and blank group by random number table method, with 40 eyes in each group. All patients were measured by IOL Master, and the actual implanted IOL power and predicted postoperative power were calculated according to Barrett universal Ⅱ formula. The uncorrected visual acuity(UCVA)and best corrected visual acuity(BCVA)at 6 mo after surgery were recorded, and the mean absolute error(MAE)was compared at 6 mo after surgery. Furthermore, the stability of postoperative refractive status and the relationship between the predicted postoperative diopter and CTR were evaluated.RESULTS:The UCVA and BCVA of the two groups were improved at 6 mo after operation(P>0.05), and there was no significant difference in UCVA and BCVA between the two groups at each time point(all P>0.05). After the implantation of IOL in 80 eyes based on the Barrett universal Ⅱ formula, the predicted postoperative diopter was -2.01±0.71 D, the actual postoperative diopter was -1.64±0.88 D, and the MAE was 0.37±0.98 D in the CTR group; in the blank group, the predicted diopter was -2.12±0.64 D, the actual diopter was -1.54±0.88 D, and the MAE was 0.58±0.31 D. The difference between the two groups was statistically significant(P<0.05). According to the axial length, CTR implantation can effectively reduce refractive error for any axial length(P>0.05). With the grouth of axial length, the MAE value increased. The postoperative MAE value of patients with axial length ≥30 mm was statistically different between the two groups(P<0.05).The proportion of hyperopic drift was 18%(7/40)in the CTR group and 30%(12/40)in the blank group, respectively, with a significant difference between the two groups(P<0.05).CONCLUSION: For patients with high myopia and cataract, the Barrett universal Ⅱ formula has high accuracy in predicting postoperative diopter. Intraoperative implantation of CTR can not only maintain the shape of the capsule bag, effectively prevent the intraoperative rupture of the suspensory ligament of the lens and make the IOL more neutral, but also is conducive to the early stability of postoperative diopter of cataract patients. It also provides more stable refractive results and reduces refractive drift. For myopic patients considering CTR implantation, it is recommended to increase the preoperative reserve diopter of -0.50 D to achieve the ideal refractive state.
