摘要:

胶质瘤是最常见且具有破坏性的原发性脑瘤。目前,临床治疗包括外科手术、放射治疗和 化学疗法等,但上述治疗手段均不能有效延长胶质瘤患者的寿命。胶质瘤固有的非均质性,侵袭浸润性、 完整的血脑屏障以及化疗耐药性是胶质瘤患者预后不良的重要原因。胶质瘤微环境具有缺氧、低 pH 高浓度的谷胱甘肽等异于正常组织的信号特点。本文针对胶质瘤的特点,总结了载药纳米递药系统在胶 质瘤治疗中的应用,包括单药纳米递送系统、多药纳米递送系统和多模纳米递送系统。载药纳米递送系 统可以通过响应胶质瘤部位的信号实现其智能化,减少对正常组织的毒性,提高对胶质瘤的治疗效果。 并进一步讨论比较了三种载药纳米递送系统在胶质瘤治疗中存在的优缺点,概述了这些载药纳米递送系 统在未来治疗胶质瘤中面临的挑战和治疗潜力。

Abstract:

Glioma is the most common and destructive primary brain tumor. The clinical treatments of glioma include surgery,radiotherapy and chemotherapy,but none of them can prolong the life span of patients effectively. The inherent heterogeneity,invasion of glioma,intact blood⁃brain barrier and chemotherapy resistance lead to the poor prognosis of glioma patients. Glioma microenvironment is characterized by hypoxia,low pH and high concentration of glutathione,which are different from normal tissues. In this paper,the drug⁃carrying nanode⁃ livery systems in the treatment of glioma has been summarized,including single⁃drug nanodelivery system,multi⁃ drug nanodelivery system and multi⁃mode nanodelivery system,with a conclusion that the intelligent nanodelivery systems can be realized by responding to the signals of glioma site and the reduced⁃toxicity to normal tissue and the therapeutic effect on glioma can be improved. The advantages and disadvantages of the three nanodelivery systemsin the treatment of glioma have been further discussed and compared. The challenges of these nanodelivery systems in the treatment of glioma in the have been summarized as well.
