AIM:To investigate the current status and influencing factors of knowledge-attitude-practice in myopia prevention and control among children and adolescents in Ningbo City, thereby providing a scientific basis for formulating targeted prevention strategies.METHODS: Children and adolescents aged 6-12 years old were selected from the medical-school collaborative myopia prevention network in Ningbo City between August 2024 and May 2025 using stratified cluster sampling. Information on myopia prevention knowledge(15 items)and practice(9 items)was collected through questionnaire surveys. Logistic regression models were used to analyze factors influencing myopia occurrence in children and adolescents.RESULTS: A total of 664 children and adolescents aged 6-12 years were enrolled in this study. Participants were divided by age into three groups: 6-7 years old(n=221), 8-9 years old(n=221), and 10-12 years old(n=222). Of the 664 questionnaires distributed, 637 valid questionnaires were returned(201 from the 6-7 age group, 235 from the 8-9 age group, and 201 from the 10-12 age group), yielding an effective response rate of 95.9%. Based on myopia screening results, the non-myopic group comprised 203 participants(31.9%), including 100 males and 103 females, with a mean age of 8.82±1.98 years old. The myopic group comprised 434 participants(68.1%), including 213 males and 221 females, with a mean age of 9.10±1.95 years old. The myopia prevalence rates in the 6-7, 8-9, and 10-12 age groups were 37.8%(76/201), 71.9%(169/235), and 94.0%(189/201), respectively(P<0.001). Regarding the knowledge and practice of myopia prevention, the overall awareness rate in the non-myopic group(59.7%±9.7%)was significantly higher than that in the myopic group(48.7%±8.5%; P<0.001). Additionally, the non-myopic group scored higher on the key practice of “regular eye examinations”(4.27±0.96)compared to the myopic group(4.10±1.05; P<0.05). Logistic regression analysis indicated that age was the primary risk factor for myopia occurrence.CONCLUSION: Age is the dominant factor in the onset of myopia, and there is a phenomenon of “knowledge-practice gap”; the traditional health education model has limitations, and a precise prevention and control system based on developmental patterns should be established.

The American Heart Association (AHA) and the American College of Cardiology (ACC), in collaboration with multiple professional organizations, jointly released the "Guideline for the Prevention, Detection, Evaluation and Management of High Blood Pressure in Adults" in August 2025. Based on the latest evidence-based medical findings from February 2015 to January 2025, the guideline proposes an individualized treatment strategy grounded in total cardiovascular disease risk stratification, incorporates the novel PREVENT risk assessment model, lowers the medication initiation threshold and control targets for high-risk populations, and provides specific management recommendations for special populations. This article provides an interpretation of these updates and conducts a comparative analysis with the current status of hypertension prevention and treatment in China as well as Chinese guidelines, aiming to offer reference for hypertension control practices in China.

Objective:To explore the current status of decision conflict in breast cancer patients with immediate breast reconstruction, and analysis the relationship with personality traits, which can provides new ideas for understanding decision-making behavior and promotes effective decision-making.Methods:A cross-sectional survey was conducted to select 175 breast cancer patients who met the inclusion and exclusion criteria for immediate breast reconstruction in Cancer Hospital of Tianjin Medical University from May to December 2022 by convenient sampling method. A questionnaire was conducted using the general information questionnaire, Revised NEO Personality Inventory, Decisional Conflict Scale, and the Control Preference Scale. Single factor analysis and multiple linear regression were used to analyze the current situation and influencing factors of decision-making conflict.Results:The 175 patients with immediate breast reconstruction were all female, aged 24-67(45.26 ± 8.01) years. The decision conflict score of 175 breast cancer patients with immediate breast reconstruction was (25.05 ± 7.05), the standardized decision conflict score was (39.14 ± 10.04), the dimension score of factors affecting decision making was(7.18 ± 2.58), the score of decision uncertainty dimension was (7.34 ± 2.28). 37 patients (21.14%) had no decision conflict, 64 patients (36.57%) had moderate decision conflict, and 74 patients (42.29%) had high level decision conflict. The scores of altruism, neuroticism, openness, sociality and moral sense of patients in this survey were (15.16 ± 3.43), (18.14 ± 4.95), (13.71 ± 3.71), (18.12 ± 4.40) and (17.46 ± 4.03) respectively. The decision conflict was negatively correlated with altruism, sociality and moral sense ( r=-0.355, -0.543, -0.331, all P<0.05), and positively correlated with neuroticism( r=0.208, P<0.05). Multivariate regression analysis showed that age, decision type, neuroticism and sociality were the influencing factors of decision conflict ( F=16.39, P<0.05), accounted for 47.1% of the variation. The variance inflation factor of the above variables was less than 10, indicating no collinearity. Conclusions:The decision conflict of breast cancer patients with immediate breast reconstruction needs to be improved urgently. Based on the influencing factors (age, decision-making type and personality traits) of decision conflict, medical staff should implement personalized decision-making aid process to meet decision-making information needs, reduce decision-making conflict and optimize decision-making quality.

In atherosclerosis, chronic inflammatory processes in local diseased areas may lead to the accumulation of reactive oxygen species (ROS). In this study, we devised a highly sensitive H₂O₂-scavenging nano-bionic system loaded with probucol (RPP-PU), to treat atherosclerosis more effectively. The RPP material had high sensitivity to H₂O₂, and the response sensitivity could be reduced from 40 to 10 μmol/L which was close to the lowest concentration of H₂O₂ levels of the pathological environment. RPP-PU delayed the release and prolonged the duration of PU in vivo. In Apolipoprotein E deficient (ApoE^‒/‒) mice, RPP-PU effectively eliminated pathological ROS, reduced the level of lipids and related metabolic enzymes, and significantly decreased the area of vascular plaques and fibers. Our study demonstrated that the H₂O₂-scavenging nano-bionic system could scavenge the abundant ROS in the atherosclerosis lesion, thereby reducing the oxidative stress for treating atherosclerosis and thus achieve the therapeutic goals with atherosclerosis more desirably.
