Molecular mechanisms of osteoarthritis using gene microarrays.

This study aimed to investigate the molecular mechanisms of osteoarthritis (OA) by microarray analysis. Three gene expression datasets GSE1919, 19664 and 55235 were downloaded from the Gene Expression Omnibus, and data of OA samples and healthy controls were used. After data preprocessing, differential expression analysis between the OA group and controls was performed using LIMMA (Linear Models for Microarray Data) package and genes with |log2FC (fold change)|>1 and P<0.

Health-promoting school development in Zhejiang Province, China.

In 2003, after three pilot projects successfully implemented WHO's Health-Promoting Schools (HPS) concept, officials in Zhejiang Province, China, expanded to additional 51 schools (93,000 students and their families and 6800 school personnel). Each school identified a health issue to begin HPS development, followed by conceptual orientation, resource mobilization, teacher training, surveys, interventions, outreach and evaluation. This study focused on the extent to which participating schools implemented the HPS concept and improved their psycho-social environments (PSEs).

Creating health-promoting schools in China with a focus on nutrition.

This pilot project in Zhejiang Province, China, aimed at improving the nutrition and health status of students, school personnel and parents, and developing a model project for nutrition interventions for the development of health-promoting schools (HPS) in China. Three primary and three secondary schools participated. Interventions included establishing school-based working groups, nutrition training for school staff, distribution of materials on nutrition, nutrition education for students, student competitions, school-wide health promotion efforts and outreach to families and communities.
