Breast cancer is the most common invasive cancer in women and the second leading cause of cancer death in women. However, it is not clear about its effective treatments. As a potential anticancer agent, grape seed procyanidins (GSPs) have been shown to inhibit the proliferation of various cancer cells in vitro and in vivo. In this study, it was shown that GSPs significantly inhibit MCF-7 cell proliferation in a concentration/time-dependent manner. The flow cytometric data clearly demonstrated that GSPs cause cell cycle arrest in the G2/M phase, followed by cell apoptosis. Moreover, it also confirmed that growth inhibition mediated by treatment with GSPs is related to the induction of apoptosis due to p53 elevation, purportedly by inhibition of the epidermal growth factor receptor (EGFR)/vascular endothelial growth factor (VEGF)/matrix metalloproteinase 9 (MMP9) pathway. Taken together, these findings suggest that GSPs inhibit MCF-7 cells proliferation and induce cell apoptosis by suppressing EGFR/VEGF/MMP9 pathway.

Background Compound glycyrrhizin has achieved outstanding results in the treatment of various skin diseases. However, the use of mesotherapy to inject compound glycyrrhizin into the skin to treat acne is still understudied. Aims This paper aims to explore the effects of mesotherapy introduction of compound glycyrrhizin injection on the acne. Materials & Methods A total of 108 patients were included in this study and divided into the control group (n = 54) and the observation group (n = 54). The control group was treated with topical clindamycin gel, while the study group was treated with topical clindamycin gel + mesotherapy and compound glycyrrhizin injection. Skin transepidermal water loss (TEWL), cuticle water content, acne severity, adverse reactions, and inflammatory reactions were documented before and after treatment in the two groups. Results The usage of mesotherapy to inject compound glycyrrhizin into the skin of acne patients more effectively treat acne than traditional clindamycin gel. The mesotherapy compound glycyrrhizin can more effectively protect the skin barrier of patients and reduce the loss of skin moisture. Compared with the traditional clindamycin gel, the combination of mesotherapy and compound glycyrrhizin more effectively inhibit the inflammatory reaction in acne patients and reduce skin damage in acne patients. Discussion/Conclusion Mesoderm introduction of compound glycyrrhizin injection has better effects on the treatment of moderate to severe acne than clindamycin gel.
