RESUMEN
Abstract@#According to the Healthy China Action Plan, Wuhan gives full play to the role of preventing and controlling student myopia by promoting student health. The primary focus is placed on education in schools, and Wuhan has integrated educational resources to develop a multi-level myopia prevention and control system and service network for school students. The network contains educational adminstrative, schools, families, and professional technical service organizations. By integrating multiple disciplines, Wuhan has built a comprehensive vision health management service system for all students. The Internet and cloud intelligent monitoring facilitated the establishment of a smart vision health management platform for students, which thoroughly and efficiently implemented myopia prevention and control to safeguard students visual health by engaging in education, monitoring, and supervision. The prevention and control of student myopia is a breakthrough for comprehensive healthy development of students. A comparison of the standard myopia rate in Wuhan in 2019 and 2018 revealed that the standard myopia rate at different learning stages of primary school, junior high school, and high school dropped by 3.31, 2.50, and 2.26 percentage points, respectively, and the rate of myopia in primary school was significantly lower than the national level. Post-epidemic surveys showed that the compliance rate and the awareness rate of the visual environment and visual behaviors of primary and secondary school students in Wuhan reached more than 80%, and prevalence of newly onset myopia or decreased vision was 30%, which was lower than the national average. The "Wuhan Model" provides an important referential framework for public health services for school students.
RESUMEN
Objective:To explore effects of trehalose as a cryopreserve agent on survival rate of fatty tissue after cryopreservation.Methods:The liposuction was used on the abdomen of adult female.After centrifugation and purification,adipose was randomized into the following three groups,the trehalose group,the fetal bovine serum (FBS)+ 10％DMSO group and the physiological saline group.The specimens were cryopreserved at-196 ℃ for 3 months and then the HE staining,glucose transfer method and CK method were used to detect the cell survival rate in each group.Results:The activity of adipose in the trehalose group and FBS+10％DMSO group adipose was higher than that in the physiological saline group (P＜0.05);while there was no significant difference between the trehalose group and FBS+10％DMSO group (P＞0.05).Conclusion:As cryoprotectant,trehalose could keep fat cell viability,and adipose tissue can be used for clinical transplantation after 3 months' freezing.
