Apios americana Medikus: A novel and promising food for postpartum uterine involution

Abstract

Pregnancy is a prolonged and tortuous process impairing puerperal health and life, in which uterine involution playing a decisive role. However, puerperae continually suffer from postpartum complications, whereas few research has focused on the postpartum recovery and uterine involution acceleration. The requirement for a safer and efficient therapy strategy for postpartum care is very urgent. The objective of this study was to explore the effects of Apios americana Medikus tuber to be a novel adjuvant therapy strategy for postpartum recovery. As a natural resource supplement, AM possesses multiple bioactivities and high biosafety, which also more acceptable for long treatment period during and after pregnancy. AM significantly altered the levels of estrogen, progesterone and their receptors, the secretion of transforming growth factor, matrix metalloproteinases, and inflammatory cytokines. In addition, it also significantly regulated various genes related to glucose and lipid metabolism, inflammation, and cell cycle, such as PLA2G3, EGR1, LCN2, and MMP9, thereby inhibiting inflammation and facilitating postpartum recovery and uterine involution. To conclude, our results suggested that AM as a promising supplementary food or a potential adjuvant treatment to accelerate postpartum uterine involution.
