Objective: To investigate the prevalence and features of ocular allergy (OA) and comorbidities among school children in Shanghai, China.
Methods: This was a population-based cross-sectional study. Each participant completed an ISAAC-based questionnaire. The prevalence of OA symptoms, allergic rhinitis (AR) asthma, atopic dermatitis (AD), and sensitization to mites, pollen, and food was analyzed.
Results: A total of 724 and 942 completed questionnaires from the 7-9-year-old (young group) and the 12-14-year-old (teen group) groups were analyzed, respectively. The overall prevalence of OA symptoms was 28%. However, more young students (10.6%) reported mild to severe daily life interference caused by OA than the teens (5.7%). The young group had higher prevalence of diagnosed allergic conjunctivitis (10.2%). The overall prevalence of AR symptom, diagnosed asthma, and diagnosed AD was 40.4%, 11.6%, and 16.7%, respectively. Young children had higher prevalence of diagnosed AR and AD than the teens. There were gender associated differences in the prevalence of AR and asthma among young children, but not among the teens. The comorbidities associated with OA was also analyzed. Sensitization to mites, food, and pollen was associated with higher prevalence of allergic conditions.
Conclusions: OA together with other allergic conditions affected a significant number of children in Shanghai.

Purpose: There is no consensus on whether cognitive measures among attention deficit hyperactivity disorder (ADHD) subtypes exhibit more similarities or differences, and most of them have been conducted on English-speaking subjects, lacking cross-cultural perspectives. The present study was aimed at investigating the intelligence structures of school-age children with ADHD who speak Chinese, using a multicenter and large sample size approach, offering some references for clinicians.
Patients And Methods: 772 children aged 6 to 12 years with ADHD took part in the cross-sectional study.
Associations between class-level factors and student physical activity during physical education lessons in China.

Physical Education Department, Central South University, Changsha, 410083, China.
Background: The purpose of this study is to explore the association between class-level factors, such as lesson start time, class size, lesson location, PE content, and PE context, and student engagement in moderate-to-vigorous physical activity (MVPA) during PE lessons in both elementary and middle schools.
Methods: A total of 284 PE lessons from ten schools in Shanghai, Eastern China, were included in the study. Students' MVPA during PE lessons was recorded using accelerometry, and lesson context was evaluated using the System for Observing Fitness Instruction Time (SOFIT).
Chitooligosaccharides promote diabetic wound healing by mediating fibroblast proliferation and migration.

Diabetic wounds are notoriously difficult to heal due to impaired cell repair mechanisms, reduced angiogenesis, and a heightened risk of infection. Fibroblasts play a vital role in wound healing by producing extracellular matrix (ECM) components and various growth factors, but their function is inhibited in diabetic wounds. Chitooligosaccharides (COS), intermediate products of chitosan degradation, have shown efficacy in promoting tissue repair, yet their role in diabetic wound healing remains underexplored.
