摘要: 目的 采用体外孵育的血性脑脊液(BCSF) 模拟蛛网膜下腔出血(SAH) 刺激因素, 观察SAH 对人脐静脉内皮细胞(HUVECs) ICAM-1 表达的影响及活血化瘀中药牛膝的有效成分蜕皮甾酮(EDS) 的干预效应。方法 体外培养人脐静脉内皮细胞, 通过免疫细胞化学染色和RT-PCR 检测对照组、BCSF 处理组和EDS 治疗组HUVECs 的ICAM-1 表达改变。结果 与对照组相比, BCSF 组HUVECs 的ICAM-1 免疫细胞化学染色增强, ICAM-1 mRNA 表达增强(P<0.01) , EDS 组弱于BCSF 组。结论 BCSF 刺激可引起HUVECs ICAM-1 的表达上调, EDS 对其具有抑制作用, 可能对慢性脑血管痉挛(CVS) 具治疗作用。

Abstract: AIM: Artificial bloody cerebrospinal fluid(BCSF) was used as pathogeny on human umbilical vein endothelial cells (HUVECs) to mimic SAH status in vivo.We tried to explore expression of ICAM-1 in HUVECs and the effect of ecdysterone (EDS).METHODS: HUVECs were used for study.BCSF was added into the culture with or without ecdysterone (200 mg·L-1) for 24 h,and then immunocytochemistry and RT-PCR were used to observe ICAM-1 expression in HUVECs.RESULTS: Following BCSF stimulation, both of immunocytochemistry and expression of ICAM-1 mRNA increased in HUVECs.EDS could reduce the expression of ICAM-1 in HUVECs following BCSF stimulation.CONCLUSION: ICAM-1expression in HUVECs could be activated directly by BCSF and reduced by EDS.EDS is possible to be a valid candidate medicine in therapy of CVS.
