RESUMEN
Objective To develop a kind of new machine for making animal model for pressure ulcer,and inspect its effect through experiments,in order to lay the foundation for the research of pressure ulcer experiments on animals.Methods This study developed the machine after reviewing the domestic and foreign literature,making full use of the existing experimental platform of our university.Then 55 Sprague Dawley(SD) rats were selected,after anesthesia and the skin preparation,the researchers imposed certain pressure with 70 mmHg/cm2 (1 mmHg=0.133 kPa) on the skin and muscle tissue on the inner left thigh of SD rats by using self-designed machine,pressing for 2 h,then reperfusion for 30 min,3 times a day,a total of 7 days.Results The authors developed a kind of new machine for making animal model for pressure ulcer,and successfully prepared Ⅲ phase pressure ulcers model in SD rats with success rate of 98.2％(54/55).Conclusion This machine can prepare Ⅲ phase pressure ulcers model on animals,it's easy to use and efficient,it can be used for researches in the field of prevention and cure of pressure ulcers.
RESUMEN
@# Objective To investigate the requirment of family rehabilitation training and provide instructions and references to guide parents practising family rehabilitation training for cerebral palsy (CP) children in Shanghai.Methods300 CP children were surveyed with the Requirement Questionnaire of Family Guidance Training Program of Rehabilitation for Cerebral Palsy Children. Then 100 children out of them were selected randomly and a visiting training and guidance of rehabilitation in family was afforded.ResultsAfter providing training and guidance of rehabilitation in family, the requirement of family rehabilitation increased from 41.5% to 92.7% ( P<0.01) and the duration and the times of training were also increased ( P<0.01).ConclusionThe families having CP children in Shanghai don't understand fully about the family rehabilitation. The visiting training and guidance program will be helpful for CP children having complete rehabilitation and coming back to society.
