The results suggested that vascular remodeling was the most prominent in LCA subjected to low shear stress accompanied by hypertension, which is regulated through the changing expression of p-Akt, p-p38, Rho GDIα. Tributyrin could affect the flow mediated carotid remodeling by both increasing apoptosis and decreasing proliferation of VSMCs through PI-3K/Akt, bcl-2, p53, p27. Tributyrin could have potential roles in treatment of vascular diseases, such as artherosclerosis and vascular restenosis, etc.

结果提示，高血压与切应力协同作用对血管重建的影响最为显著，Akt、p38和Rho GDIα信号通路参与了高血压与低切应力诱导的血管重建过程；Tributyrin对血管重建的干预作用是通过影响PI-3K信号通路，调节凋亡相关蛋白bcl-2以及细胞周期调控蛋白p53和p27的表达水平而实现的；Tributyrin有可能成为一种在动脉粥样硬化、血管再狭窄等疾病防治中有潜在临床应用价值的药物。
