摘要
骨缺损引起的骨疾病是现代医学非常棘手的一种疾病,正常的骨组织发生病变或外部因素的物理损伤都会形成难愈合的骨缺损;骨缺损部位复杂的微环境决定其治疗条件也更苛刻.构建可以用于骨缺损的支架是骨组织工程技术的一个重要方向,也是解决骨缺损疾病难题的重要手段.本文简单介绍了羟基磷灰石/氧化石墨烯(HA/GO)复合材料的制备原理和方法,细胞实验表明HA/GO对骨细胞没有明显的毒性,粗糙的表面结构更有利于骨细胞的增殖分化,在此基础上详细介绍了用于治疗骨缺损疾病HA/GO复合支架的构建方式及其性能.最后讨论了HA/GO复合支架在骨疾病治疗中的发展前景和面临的挑战.
Abstract
Bone defects caused by bone diseases are a very challenging issue in modern medicine.Both pathologi-cal changes in normal bone tissue and physical damage caused by external factors can lead to difficult-to-heal bone defects.The complex microenvironment of the bone defect site makes treatment conditions more demanding.Con-structing scaffolds for bone defects is an important direction in bone tissue engineering technology and a crucial means to solve the problem of bone defect diseases.This article briefly introduces the preparation principles and methods of hydroxyapatite/graphene oxide(HA/GO)composite materials.HA/GO has no apparent toxicity to bone cells,and its rough surface structure is more conducive to the proliferation and differentiation of bone cells.Based on this,the construction methods and performance of HA/GO composite scaffolds for treating bone defect diseases are described in detail.Finally,the development prospects and challenges of HA/GO composite scaffolds in the treatment of bone diseases are discussed.
