缺血性卒中具有高发病率、高致死致残率等特点，其致病机制错综复杂，临床上防治困难，严重危害我国居民健康。阐明致病机理，对缺血神经多靶点保护、减轻“缺血瀑布”反应是未来研究神经保护药物的关键。近些年研究发现，小细胞外囊泡（small extracellular vesicles, sEVs）具有细胞主动分泌、携带蛋白质和核酸信息、在细胞之间进行信息传递的特性，不仅参与了多种疾病的发生发展进程，还因其能...
关节软骨缺损是最常见的骨科疾病之一，可引起关节功能障碍、严重疼痛和残疾，给患者个人和社会带来沉重的经济负担。不幸的是，由于软骨无神经无血管的特性，软骨缺乏自愈能力，因此关节软骨的再生仍然是一个相当大的挑战。组织工程通过理想的种子细胞、合适的生物材料和生物活性分子的结合，被认为是一种很有前途的软骨修复方法。
