Relationship between exposure to mobile phones and other electronic products and the ability development in children / 中华实用儿科临床杂志

Objective:To identify the relationship between exposure to mobile phones and other electronic products and the ability development in children.Methods:Retrospective study.A total of 218 children aged 0.5-6.0 years presented to the Department of Health Care, Beijing Children′s Hospital, Capital Medical University form September 2019 to June 2020 for developmental examination were included.Those with nervous system, mental system diseases, endocrine system diseases and premature children were excluded.Their development was evaluated and the information about exposure to mobiles phones and other electronic products were collected. Chi- square test and Fisher′ s exact probability method were used to analyze the relationship between the exposure to mobile phones and other electronic products and the ability development in children.The influencing factors of children′s development in various fields were analyzed by the binary Logistic regression. Results:Abnormal fine movements of children aged 0.5-0.9 years were related to the latest time every night of exposure ( P<0.05). Abnormalities of adaptability, language and social self-care in children aged 1.0-2.9 years and abnormality of language in children aged 3.0-5.9 years were correlated with the number of hours of daily exposure (all P<0.05). Abnormalities of language and social self-care in children aged 1.0-2.9 years and abnormalities of adaptability, language and social self-care in children aged 3.0-5.9 years were correlated with the purposes of exposure (all P<0.05). Binary Logistic regression analysis indicated that the children′s gross motor was affected by the number of hours of daily exposure ( OR=1.868, P<0.05). The children′s fine motor movements were affected by mother′s educational level and the latest time every night of exposure ( OR=1.722, 2.355, all P<0.05). The children′s adaptability was affected by mother′s educational level, child caregivers, the number of hours of daily exposure and the latest time every night of exposure ( OR=1.711, 2.866, 1.895, 1.650, all P<0.05). The children′s speech was affected by the number of hours of daily exposure, the latest time every night of exposure, and the purposes of exposure (telephone or video phone, early education or study)( OR=2.348, 1.806, 0.328/0.350, all P<0.05). The children′s social interaction and self-care delay were affected by mother′s educational level, the number of hours of daily exposure and the purposes of exposure (telephone or video phone, early education or study)( OR=1.647, 2.678, 0.307/0.363, all P<0.05). Conclusions:The adverse effects of exposure to mobile phones and other electronic products on children should be well concerned.The exposure time of developing young children should be strictly controlled to prevent the adverse effects on the nervous system and development in children.For children who were already affected, relevant habits and behaviors should be timely corrected to avoid irreversible damages.

Strategy for enhancing research ability of the medical students / 中华医学教育探索杂志

The importance and necessity of undergraduates participating in the training plan of the medical research was clarified.Based on the actual ability of students and the characteristic of experimental teaching plan,we think that combination of experimental teaching of small group with research training is a strategy for enhancing the ability of the medical undergraduates to do research.This proposal will speed up the medical educational goal by the activation of novel idea,the cultivation of innovatory thought and the enhancement of creative ability.

Reformation of Medical Education and the Curriculum System for the New Century / 医学教育

To adapt to the demand for highly talented medical personnel in the new century, China Medical University has proposed a teaching reformation policy that aims to reinforce the combination of training goals with all subjects; to carry out bilateral infiltration and three optimizations; to emphasize the development of knowledge, ability and quality; to enliven teaching methods; and to make adaptations in all areas. In preparation, we have studied the reform experiences and current practices of more than 200 medical colleges and universities around the world in light of current conditions in China and China Medical University. We have also renewed our recognition of the training goals of specialties as a firm basis for the quality education of skilled doctors. The University has reformed its curriculum system and teaching plans for clinical medical specialties in many ways and has adjusted its teaching contents to form a new model for training talented medical personnel for the next century.
