简介：AbstractPlatelet-rich fibrin (PRF) is a second-generation platelet concentrate obtained from autologous blood. PRF is composed of abundant platelets, leucocytes, and a high concentration of various growth factors and fibrinogen. The composition and three-dimensional structure of PRF enable it to effectively make cells migrate and proliferate, playing an important role in tissue repair. Furthermore, the easy preparation and low cost of PRF make it a good treatment option. Numerous articles have been published about the application of PRF in clinical practice, however, the application of PRF in dermatology has not been comprehensively reviewed. The objective of this review article was to discuss various applications of PRF in dermatology, including healing chronic wounds, treating androgenic alopecia, skin rejuvenation, autologous fat transplantation, and treating vitiligo. PRF is a promising dermatologic treatment, but lacks a standardized protocol regarding its methods of attainment and use, which needs more investigations.

简介：RICH教学在浙江师范大学外国语学院的最初实践始于1980年代末，到1990年代中期形成系统，并得到一定程度的推广。但其在实践中仍主要从教书与育人两个方面提出了当前教师在教学中所应该贯彻的一贯思路，其最主要任务是引导学生成长，努力将学生培养成心智健康发展的对社会有用的人才。但由于该任务过于宏伟，使得在执行过程中由单个或者单科老师来实施，显得过于困难。若要真正推行RICH教学理念，需要所有各门课程教师的真诚合作、对所有教材的重新整理，并需要学院甚至学校层面自上而下的行政支持。
