沙利度胺联合曲安奈德抑制人脐静脉内皮细胞增殖的研究

目的:研究沙利度胺(thalidomide)联合曲安奈德对人脐静脉内皮细胞(HUVEC)的药物作用.方法:Ⅰ型胶原酶消化法原代培养HUVEC, Ⅷ因子相关抗原检测法鉴定细胞.沙利度胺溶于0.5%二甲基亚砜(DMSO)中,分为3组.A组为沙利度胺组,分4个浓度梯度,分别为10、25、50和75 mg/L;B组为沙利度胺+曲安奈德组,为含1 mg/L曲安奈德的各浓度沙利度胺;C组为对照组.HUVEC传代植入96孔板,细胞密度为1×10~4/mL,过夜,加入不同浓度的药物,处理72 h; 在酶标仪570 nm波长处读取吸光度(A)值. 结果: 2组药物均对HUVEC的增殖有明显的抑制作用 (P < 0.01),抑制作用与药物浓度呈正相关;与A组相比,B组对HUVEC抑制作用更强(P < 0.05).结论:沙利度胺及曲安奈德对血管内皮细胞增殖有明显作用,这两类药物在治疗新生血管性疾病中可发挥一定作用.

The Effect of Thalidomide and Triamcinolone Acetonide on Human Umbilical Vein Endothelial Cells

Objective: To investigate the effect of thalidomide and triamcinolone acetonide (TA) on human umbilical vein endothelial cells (HUVEC). Methods: The primary culture of HUVEC with collagenase Ⅰ was identified with FⅧAg. There were 3 groups in the study including thalidomide group(10, 25, 50 and 75 mg/L), TA and thalidomide group and control group. The absorbance ratio was measured through MTT-test. Results: Both thalidomide group and TA and thalidomide group showed inhibitor effect on the growth of HUVEC significantly(P < 0.01). The inhibitory effect was dose dependent. Compared to thalidomide group, the inhibitory effect was more significant in TA and thalidomide group(P < 0.05). Conclusion: Thalidomide can inhibit the growth of HUVEC; however, the effect was more significant in TA and thalidomide group.
