Currently, the treatment methods for liver cancer mainly include surgical resection, radiation therapy, chemotherapy, and interventional therapy, etc. However, these treatment methods have serious side effects and limitations, so finding new treatment methods is urgently needed. In recent years, RNA interference (RNAi) as a new gene therapy method has gradually attracted attention, and its application in liver cancer treatment has also increased. However, RNAi still needs to be further optimized and improved in terms of efficacy and safety.In recent years, ultrasound irradiation technology as a new method of RNA delivery has gradually become a research focus. Ultrasound irradiation can increase cell membrane 精品文档---下载后可任意编...
