- 纳米技术纳米技术
- 癌症治疗 癌症治疗
背景情况:
- 光热疗法 (PTT) 提供精确的癌症治疗,毒性低于传统方法.
- 在PTT的挑战包括不完整的瘤根除和健康组织的损伤.
- 将PTT与化疗相结合可以提高治疗结果.
研究的目的:
- 开发一种可注射的超分子水凝 (MDGel) 用于双重协同的癌症治疗.
- 将MXene-doxorubicin (MD) 复合物整合到近红外 (NIR) PTT和化疗的水凝中.
- 评估MDGel系统的体外和体内疗效.
主要方法:
- 使用凝-环氧化 (GE-CD) 和氨酸-阿达曼坦 (HA-AD) 之间的宿主-客人相互作用制造MDGel.
- 将MXene-doxorubicin (MD) 复合物加载到水凝中以控制释放.
- 在小鼠模型中对体外癌细胞死亡和体内瘤抑制的评估.
主要成果:
- MDGel证明了MD复合物的有效分散,并在NIR照射时触发了药物释放.
- 在体外研究表明,由于PTT和化疗的协同作用,近80%的癌细胞死亡.
- 在体内研究中,在皮肤癌小鼠模型中实现了68.9%的瘤体积减少,没有显著的不良影响.
结论:
- 开发的MDGel系统为双重协同的癌症治疗提供了一个多功能平台.
- 与化疗相结合的NIR触发的PTT提供了局部化和有效的治疗策略.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
