摘要:目的 探讨糖网明目颗粒不同提取部位对高糖诱导的人脐静脉内皮细胞EA.hy926中血管内皮细胞生长因子(VEGF)和白细胞介素(IL)-1α基因和蛋白表达的作用机制。方法 人脐静脉内皮细胞EA.hy926分为空白组、高糖组、全方组、部位1(苷类和黄酮类)组、部位2(有机酸类和多糖类)组和部位3(生物碱类)组。以D-葡萄糖干预细胞复制高糖模型,半定量RT-PCR检测糖网明目颗粒不同提取部位对高糖诱导细胞中VEGF和IL-1α的基因表达;ELISA检测糖网明目颗粒不同提取部位对高糖诱导的细胞中VEGF和IL-1α的蛋白表达。结果 高糖导致EA.hy926细胞VEGF和IL-1α mRNA和蛋白表达显著升高(P<0.05)。糖网明目颗粒及其不同提取部位干预细胞后,VEGF和IL-1α基因和蛋白表达显著降低(P<0.05),变化幅度依次为:部位1>部位3>部位2。结论 糖网明目颗粒中苷类和黄酮类、生物碱类及有机酸类和多糖类调控高糖诱导的血管内皮细胞VEGF和IL-1α表达的作用强度依次减弱。

Abstract: Objective To observe the mechanism of action of different extracts of Tangwang Mingmu Granules on high glucose induced VEGF and IL-1α gene and protein expressions in vascular endothelial cells. Methods Human umbilical vein endothelial cells EA.hy926 were divided into six groups: blank, high glucose, Tangwang Mingmu Granules, extract 1 (glycoside and flavonoid), extract 2 (organic acid and polysaccharides) and extract 3 (alkaloids) groups. High concentration glucose was used to establish the high glucose model in EA.hy926 cells. The expressions of VEGF and IL-1α mRNA were detected by semi-quantitative RT-PCR. The contents of VEGF and IL-1α protein were tested by ELISA. Results The gene expression and protein levels of VEGF and IL-1α were significantly up-regulated under the high glucose condition (P<0.05). However, the above indicators were significantly reduced after the treatment of Tangwang Mingmu Granules. The activity of different parts of Tangwang Mingmu Granules was as follows: extract 1> extract 3> extract 2. Conclusion The action intensity of glycosides and flavonoids, alkaloids, organic acids and polysaccharides on VEGF and IL-1α expression in Tangwang Mingmu Granules weakens in sequence.
