摘要:
目的 探讨选择性Xa因子抑制剂利伐沙班(RVXB)对apoE-/-小鼠颈动脉粥样硬化斑块内炎症因子表达的影响。方法 20只apoE-/-小鼠随机分为对照组和利伐沙班组(每组10只)。所有小鼠通过高脂喂养及颈动脉套管方法建立颈动脉粥样硬化斑块模型。8周后,对照组小鼠接受生理盐水灌胃,而利伐沙班组小鼠接受每天5 mg/kg剂量利伐沙班灌胃;给药4周后,测量小鼠体质量并处死小鼠。采用Western blot方法检测斑块内IL-6,TNF-α和MMP9蛋白表达水平。结果 与对照组相比,利伐沙班组小鼠的体质量及血脂水平无显著改变;斑块内IL-6,TNF-α和MMP9蛋白表达水平显著降低(均P<0.05)。结论 利伐沙班能够抑制动脉粥样硬化斑块内炎症因子的表达。
Abstract:
AIM To investigate how rivaroxaban, an FXa alternative inhibitor, influences the inflammatory factor expression in carotid atherosclerotic plaques in apoE-/- mouse. METHODSWe divided 20 apoE-/- mice randomly into control group and rivaroxaban group (n=10 each). The models of carotid atherosclerotic plaques were established with high-fat food and carotid artery casing in all mice. After 8 weeks, mice in the control group were given physiological saline by intragastric administration and mice in the rivaroxaban group were given rivaroxaban 5 mg/kg by intragastric administration. After 4 weeks of continuous administration, mice were euthanized after body weight was measured. The expression levels of IL-6 (interleukin-6), TNF-α (tumor necrosis factor-alpha) and MMP9 (matrix metalloproteinase 9) in plaques were measured by Western blot. RESULTSCompared with those in the control group, the weight and lipid levels in the rivaroxaban group were not obviously changed, but the expression levels of IL-6, TNF-α and MMP9 were reduced significantly (P<0.05). CONCLUSIONRivaroxaban inhibits inflammatory factor expression in atherosclerotic plaques.
