摘要: 目的 探讨制何首乌、巴戟天及二者配伍,对氧化型低密度脂蛋白(ox-LDL)诱导的人脐静脉内皮细胞(HUVEC)损伤的影响,以示临床。方法 建立ox-LDL诱导的HUVEC损伤模型,分别用制何首乌、巴戟天、二者配伍的水煮物干预,检测HUVEC的细胞增殖、相对活率、细胞凋亡率、细胞周期、NFκB mRNA的表达。结果 ①制何首乌、巴戟天均能抑制ox-LDL诱导的HUVEC凋亡,二者配伍的抑制作用强于单味中药制何首乌。②制何首乌、巴戟天均能延长ox-LDL诱导的HUVEC的细胞周期(S+G2)%,制何首乌、巴戟天的延长作用相似,二者配伍的延长作用强于单味中药制何首乌、巴戟天。③制何首乌组、巴戟天组的NFκB mRNA的表达量下降,制何首乌组的抑制作用强于巴戟天组,二者配伍的抑制作用强于单味中药制何首乌、巴戟天。结果 制何首乌、巴戟天均能抑制ox-LDL诱导的HUVEC损伤,二者配伍的作用强于单味中药制何首乌、巴戟天。

Abstract: Objective To investigate the effects of Polygonum multiflorum praeparata, Morinda officinalis and their compatibility on ox-LDL-induced injury of human umbilical vein endothelial cells(HUVEC). Methods We established an ox-LDL-induced HUVEC injury model, made intervention with Polygonum multiflorumpraeparata, Morinda officinalis and their compatibility, the HUVEC cell proliferation, relative viability, apoptosis, cell cycle, NFκB mRNA were detected. Results ①Both Polygonum multiflorumpraeparata, Morinda officinalis reduced the apoptosis rate of HUVEC, and their compatibility had a stronger effect on reducing the apoptosis rate of HUVEC than single Polygonum multiflorumpraeparata. ②Both Polygonum multiflorumpraeparata, Morinda officinalis increased the HUVEC cell cycle (S+G2)%, the extension between Polygonum multiflorumpraeparata and Morinda officinalis was similar, and their compatibility increased HUVEC cell cycle (S+G2)%, it was stronger than single Polygonum multiflorumpraeparata and single Morinda officinalis. ③Both Polygonum multiflorumpraeparata and Morinda officinalis down-regulated the expression of NFκB mRNA in HUVEC, their compatibility down-regulated HUVEC NFκB mRNA expression,it was stronger than Polygonum multiflorumpraeparata, Morinda officinalis. Conclusion Polygonum multiflorumpraeparata, Morinda officinalis and their compatibility can inhibit ox-LDL-induced HUVEC injury, and their compatibility inhibition is stronger than single Polygonum multiflorumpraeparata, and Morinda officinalis.
