摘要:

背景:前期研究发现醒脑静能有效抑制兔心肌缺血再灌注模型的炎症递质及促纤溶作用,但是影响纤溶系统活性的作用机制未完全明确。

目的:观察醒脑静对重组人肿瘤坏死因子α介导人脐静脉内皮细胞分泌组织型纤溶酶原激活物和纤溶酶原激活物抑制剂1及其基因表达的影响。
方法:取3-5 代人脐静脉内皮细胞,在培养基中添加10 μg/L 重组人肿瘤坏死因子α介导人脐静脉内皮细胞分泌组织型纤溶酶原激活物和纤溶酶原激活物抑制剂1及其基因表达,醒脑静组加入不同浓度(5,10,20 mL/L)的醒脑静干预,阳性对照组添加氟伐他汀(1 μmol/L),并设立单纯人脐静脉内皮细胞培养的空白对照组。培育24 h后采用酶联免疫吸附双抗体夹心法(ELISA)检测细胞上清液组织型纤溶酶原激活物和纤溶酶原激活物抑制剂1水平;采用反转录聚合酶链反应检测人脐静脉内皮细胞的组织型纤溶酶原激活物和纤溶酶原激活物抑制剂1的mRNA表达。

结果与结论:重组人肿瘤坏死因子α组纤溶酶原激活物抑制剂1分泌和mRNA表达较空白对照组显著升高 (P < 0.05),组织型纤溶酶原激活物分泌和mRNA表达较空白对照组显著降低(P < 0.05)。不同浓度醒脑静组纤溶酶原激活物抑制剂1分泌和mRNA表达均较重组人肿瘤坏死因子α组显著降低(P < 0.05),而组织型纤溶酶原激活物分泌和mRNA表达均较重组人肿瘤坏死因子α组显著升高(P < 0.05),且呈剂量依赖关系。结果证实,醒脑静作用可逆转重组人肿瘤坏死因子α所致的人脐静脉内皮细胞的纤溶活性。

Abstract:

BACKGROUND: We have found that Xingnaojing can effectively inhibit mediators of inflammatory mediators and promote fibrinolytic activity in a rabbit model of myocardial ischemia and reperfusion. However, it is not completely clear what is the action of mechanism of fibrinolytic system activity in human umbilical vein endothelial cells.

OBJECTIVE: To investigate the effects of Xingnaojing on recombinant human tumor necrosis factor α-mediated tissue-type plasminogen activator (t-PA) and plasminogen activator inhibitor-1 (PAI-1) expression in human umbilical cord vein endothelial cells.
METHODS: The passages 3-5 of human umbilical cord vein endothelial cells were obtained, and were induced by adding 10 μg/L recombinant human tumor necrosis factor α in the culture medium. Xingnaojing in different concentrations (5, 10, 20 mL/L) were injected in the Xingnaojing group, and fluvastatin (1 μmol/L) was added as positive control group. A blank control group of simple human umbilical cord vein endothelial cells culture was set up. After 24 hours of cultivation, the production of t-PA and PAI-1 in the cultured medium was determined by ELISA. The mRNA expression of t-PA and PAI-1 was measured by reverse transcript-PCR.

RESULTS AND CONCLUSION: Compared with the blank control group, the secretion and mRNA expression of PAI-1 in the group treated with recombinant human tumor necrosis factor α (10 μg/L) were significantly increased (P < 0.05); however, the secretion and mRNA expression of t-PA in the group treated with recombinant human tumor necrosis factor α (10 μg/L) were significantly decreased (P < 0.05). The secretion and mRNA expression of t-PA were significantly higher in the Xingnaojing group at different concentrations than in the recombinant human tumor necrosis factor α group (P < 0.05); however, the secretion and mRNA expression of PAI-1 were significantly lower in the former group than the latter group (P < 0.05), which was in a dose-dependent manner. Xingnaojing can effectively improve the fibrinolytic function of human umbilical cord vein endothelial cells mediated by recombinant human tumor necrosis factor α.
