骨缺损是临床上的常见病,据统计,我国每年因疾病、创伤、肿瘤等造成的骨缺损病人超过100万,大范围骨缺损的修复目前仍是骨科治疗的难题之一。 Bone defects are common clinical diseases. According to statistics, the number of patients with bone defects caused by diseases, trauma, and tumors exceeds 1 million per year. The repair of large-scale bone defects is still one of the difficult problems in orthopedic treatment. 关节软骨自身修复仅限于较小的缺损或者轻微的病变。由于运动损伤、疾病等原因引起的关节软骨损伤自身无法修复或者修复效果欠佳将最终发展成为骨性关节炎,并形成恶性循环。因此如何很好的修复关节软骨损伤和病变一直以来都是骨科领域的热点和难点问题 。 Articular cartilage self-repair is limited to minor defects or minor lesions. Articular cartilage damage caused by sports injuries, diseases, etc., which cannot be repaired by itself or poorly repaired, will eventually develop into osteoarthritis and form a vicious circle. And therefore, how to repair articular cartilage damage and lesions has always been a hot and difficult problem in the field of orthopedics. 采用负载基因载体/功能基因复合纳米粒子的PLGA/纤维蛋白凝胶支架用于新西兰大白兔软骨缺损的再生,取得了较好的修复效果。另外,还可以采用骨缺损模型进行骨支架材料的评价,相关论文发表在Biomaterials(IF 8.3)、Journal of Tissue Engineering and Regenertive Medicine (IF 4.4)等杂志上。 PLGA/fibrin gel scaffolds loaded with gene vector/functional gene composite nanoparticles were used to regenerate cartilage defects in New Zealand white rabbits, and a good repair effect was obtained. In addition, bone defect models can be used to evaluate bone scaffold materials. The related papers are published in the journals Biomaterials (IF 8.3), Journal of Tissue Engineering and Regenertive Medicine (IF 4.4). —————————— 文章来源: http://www.qingzitech.net/bone-and-cartilage-repair-materials
