Abstract:

目的研究枸杞多糖对极长链酰基辅酶A脱氢酶缺陷症(VLCADD)患者皮肤成纤维细胞长链酰基肉碱的作用。方法以体外培养的VLCADD患者及健康志愿者皮肤成纤维细胞为实验材料,以棕榈酸为特殊培养溶媒底物,经96h培养后应用串联质谱分析技术,分析在0.4mg?L-1枸杞多糖干预后皮肤成纤维细胞内相应长链酰基肉碱的浓度变化。结果患者组在枸杞多糖干预后皮肤成纤维细胞内长链酰基肉碱月桂酰肉碱(C12)、肉豆蔻酰肉碱(C14)、及棕榈酰肉碱(C16)均明显降低,乙酰肉碱(C2)明显增高(均P<0.05),而健康对照组在枸杞多糖干预后长链酰基肉碱C12、C14∶1、C14、C16以及乙酰肉碱与无枸杞多糖干预相比未见明显变化,差异无统计学意义。结论枸杞多糖降低经体外培养VLCADD患者皮肤成纤维细胞长链酰基肉碱的浓度,减轻长链酰基肉碱的蓄积,其作用机制可能与枸杞多糖的抗氧化应激的作用有关。
