摘要(Abstract):
目的观察血脉宁颗粒对血管内皮细胞(VEC)p-选择素(p-selectin)表达的影响,以探讨血脉宁保护血管内皮细胞的机理。方法以高脂血清、高脂血清加含药血清培养内皮细胞;ELISA法检测培养上清液p-selectin,流式细胞术检测内皮细胞表面p-选择素表达,RT-PCR检测p-selectinmRNA表达,Western-Bloting检测p-selectin蛋白。结果造模组血管内皮细胞表面p-选择素表达明显增高;血脉宁组内皮细胞表面p-选择素表达明显低于造模组。结论高脂血清可损伤ECV,增高ECV表面p-选择素表达;血脉宁含药血清可以使损伤的ECV表面p-选择素表达下降,具有保护损伤ECV的作用,其机理与其降低ECV表面p-选择素表达有关。
