  • EBM联合PBL教学模式在医学本科生临床见习中的应用

    提高医务人员的临床业务能力,培养更多具备扎实临床技能的医务人员,可以满足人民对高质量健康生活的不断追求。而如何立足临床医学本科教育,积极探索先进的教学模式,是培养优秀临床医生的基石。将循证医学(Evidence based medicine,EBM)引入到问题导向学习(Problem based learning,PBL)教学法中,可以更加高效地提高学生发现问题并寻找问题答案的积极性,为将来快速提升临床疾病处理能力奠定扎实基础。本研究将四川大学华西临床医学院的临床见习本科生作为研究对象,按照随机数字表将学生随机分为PBL组和EBM+PBL组,评估对比两种教学模式的教学效果和满意度。结果发现,与PBL组相比,EBM联合PBL教学模式可以充分激发学生的主动学习意识,提高临床相关知识的掌握情况,培养学生的临床思维能力与团队合作精神,为将来成为一名合格的临床医师奠定基础。

  • Application and research progress of 3D printing magnesium-based biological scaffolds in the field of bone regeneration

    In recent years, 3D printing technology, as a new material processing technology, can precisely control the macroscopic and microstructure of biological scaffolds and has advantages that traditional manufacturing methods cannot match in the manufacture of complex bone repair scaffolds. Magnesium ion is one of the important trace elements of the human body. It participates in many physiological activities of the body and plays a very important role in maintaining the normal physiological function of the organism. In addition, magnesium ions also have the characteristics of promoting the secretion of osteogenic proteins by osteoblasts and osteogenic differentiation of mesenchymal stem cells. By combining with 3D printing technology, more and more personalized magnesium-based biological scaffolds have been produced and used in bone regeneration research in vivo and in vitro. Therefore, this article reviews the application and research progress of 3D printing magnesium-based biomaterials in the field of bone regeneration and repair.

  • Hydrogel-based vascularization strategy in the field of bone tissue engineering

    Bone tissue regeneration and blood vessel formation are inseparable. How to realize the vascularization of bone repair scaffolds is an urgent problem in bone tissue engineering. The growth and development, mineralization maturity, reconstruction and remodeling, and tissue regeneration of bone are all based on forming an excellent vascularization network. In recent years, more and more researchers have used hydrogels to carry different cells, cytokines, metal ions and small molecules for in vitro vascularization and application in bone regeneration. Based on this background, this article reviews the hydrogel-based vascularization strategies in bone tissue engineering.
