低频超声靶向微泡破坏技术的协同抗肿瘤机制研究及应用进展

Synergistic Anti-tumor Mechanisms of Low-frequency Ultrasound-targeted Microbubble Destruction:Mechanisms and Application

超声造影剂微泡联合低频超声可对深处肿瘤进行治疗,即低频超声靶向微泡破坏技术,逐渐成为一种高效、无创的抗肿瘤方式,其通过物理生物效应可以提高药物转运效率、破坏肿瘤新生血管,从而增强化学、基因、免疫、抗血管治疗。此外,该技术还可应用于声动力治疗,并且在复合纳米颗粒的基础上实现协同治疗,增强抗肿瘤效率,为以后肿瘤的靶向治疗提供新方法。

Ultrasound contrast agent microbubbles combined with low frequency ultrasound named as low-frequency ultrasound-targeted microbubble destruction technology has become an effective and non-invasive anti-tumor therapy for deep tumors.It can enhance the efficacies of chemotherapy,gene therapy,immunotherapy,and anti-angiogenic therapy by improving cell membrane permeability and destroying tumor neovasculature.It can be applied to sonodynamic therapy and realize multimodal synergistic therapy on the basis of nanoparticles,which increases the anti-tumor efficiency and offers a promising target therapy for tumors.
