ABSTRACT

Overtaking lung cancer,breast cancer is now the most commonly diagnosed cancer seriously threatening people's health and life. As the main effective component of Tripterygium wilfordii,triptolide( TP) has attracted increasing attention due to its multitarget and multi-pathway anti-tumor activity. Recent studies have revealed that breast cancer-sensitive TP enables the inactivation of breast cancer cells by inducing tumor cell apoptosis and autophagy,interfering in tumor cell metastasis,resisting drug resistance,arresting tumor cell cycle,and influencing tumor microenvironment. It has been recognized as a promising clinical antitumor agent by virtue of its widely accepted therapeutic efficacy. This paper reviewed the anti-breast cancer action and its molecular mechanisms of TP on the basis of the relevant literature in the past ten years,and proposed application strategies in view of the inadequacy of TP to provide a reference for further research on the application of TP in the treatment of breast cancer.

ABSTRACT

In recent years, multi-modal combined anti-tumor has become an effective strategy for clinical tumor treatment. Photothermal therapy with its characteristics of minimally invasive, controllable, high efficiency, and strong specificity, can effectively make up for the toxic side effects and tumor resistance caused by traditional drug treatment. The research shows that the combination of photothermal therapy and chemotherapy has better synergistic antitumor effect. However, chemotherapeutic drugs and photothermal agents may have different pharmacokinetic behaviors in vivo, so it is difficult to ensure their effective transmission in tumor site, and the free form is easy to be metabolized and degraded in vivo. How to deliver the two therapeutic modes of drugs / photothermal reagents to tumor tissues in a specific, efficient and synchronous manner to achieve the best combined antitumor effect is an important problem to be solved in the combined antitumor application. The development of nano-drug delivery technology provides a new idea for the application of tumor treatment. In this paper, combined with the latest research progress in this field, the anti-tumor mechanism of photothermal therapy combined with chemotherapy, the advantages of nano drug delivery, the types and characteristics of commonly used nano materials and the principle of drug delivery are reviewed in order to provide a reference for the further development of multi-mode combined treatment of tumor.
