Estrogen deficiency can increase the mRNA expression of MMP-1、MMP-3 and IL-1β in OA synovia tissue. Estrogen could inhibit the mRNA expression of MMP-1、 MMP-3 and IL-1β in OA synovia tissue. Progestin could even decrease this expression. Estrogen could slightly increase the mRNA expression of TIMP-1. It is suggested that low dose of estrogen supplement play a protective effect on OA cartilage, and progestin could increase this protective effect.

雌激素缺乏可使OA关节滑膜中MMP-1、MMP-3和IL-1β mRNA表达增加，雌激素对关节滑膜组织中MMP-1、MMP-3和IL-1β mRNA表达有抑制作用，孕激素可增强雌激素的这一抑制作用，雌激素对TIMP-1有轻度升高作用，提示低剂量雌激素对OA关节软骨有一定保护作用，而加用孕激素这一保护作用增强。
