[Mechanisms and application of triptolide against breast cancer].

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.

Concurrence of Multiple Cutaneous Malignancies on Sun-exposed Vitiligo Skin of a Patient: A Case Report and Review of the Literature.

There are very few published studies in the literature examining the association between vitiligo and skin cancers and only some anecdotal reports about phototherapy-associated nonmelanoma skin carcinoma (NMSC) in patients with vitiligo. Herein, we report a case of an 84-year-old male with widespread vitiligo with concurrent onset of two primary cutaneous malignancies in sun-exposed vitiligo skin. The association between vitiligo and NMSC deserves further assessment. Chronic sun damage might be a possible causative factor for the development of NMSC in the vitiligo patient.
