莪术提取物调控支架后再狭窄血管平滑肌细胞增殖的研究进展

摘要

血管平滑肌细胞( vascular smooth muscle cells, VSMCs)异常增殖是支架后再狭窄(in-stent restenosis, ISR)的主要病理过程。近年来研究表明,莪术提取物具有抑制VSMCs 增殖,进而抑制支架后再狭窄的作用,其发挥作用的有效成分主要有姜黄素和β-榄香烯,其可能的机制与抑制血红素氧合酶-1(hemeoxygenase-1, HO-1)表达、细胞外信号调节激酶(extracellular signal-regulated kinase, ERK) MAPK、Akt 信号通路,阻滞细胞周期进程相关。该文就近年来莪术提取物调控支架后再狭窄 VSMCs 增殖的研究进展作一综述。%Vascular smooth muscle cells (VSMCs) proliferation is the critical pathological process of in-stent restenosis (ISR). Recent researches indicate that the traditional Chinese medicine curcuma zedoary (E’zhu) can inhibit VSMCs proliferation, with a potential value in preventing and treating ISR. The major ac-tive components of curcuma zedoary are curcuma and β-elemene. The underlying mechanisms involve the inhibition of hemeoxygen-ase-1 expression, blockade of extracellular signal-regulated ki-nase – MAPK and Akt pathways, and subsequent cell cycle ar-rest. This article reviews the recent progress on curcuma zedoary extracts regulating VSMCs proliferation in ISR.
