RESUMO
With the rapid development of cell biology and biological materials, the dentine-pulp complex regeneration research has gone further. Scaffolds play important roles in the construction of tissue engineered dentine-pulp complex. At present, scaffolds used in dentine-pulp complex regeneration include not only natural biological materials and synthetic biomaterials, but also various composite materials and cell- or body-based carrier materials. In this paper, the latest research status of various scaffolds for dentine-pulp complex regeneration were reviewed. The advantages and problems of these scaffolds were analyzed. The future development direction was predicted.
RESUMO
Nursing management is an important part of hospital management,the head nurses,as leaders and organizers of first-line clinical nursing work of the hospital,play a decisive role in hospital nursing management.As the first-line managers and organizers,the head nurse management level and ability is directly related to the hospital nursing quality and the overall quality of nurses.The implementation of the performance appraisal and management by objectives in current nursing management has been more and more used in the hospital.This article aimed to review the management by objective and quantitative assessment home for head nurse at home and abroad,in order to help nursing managers to learn and master performance appraisal of head nurses,comprehensively improve quality of head nurses,promote the improvement of nursing quality,and push the development of nursing course.
