Effects of HQD on the intracellular and extracellular concentration of NADPH oxidase. (a) Western blot for NADPH oxidase subunits including gp91phox, p67phox, p47phox, p40phox, p22phox, and Ras-1. (b)–(g) Statistical analysis of (a). (h) Extracellular concentration of NADPH oxidase. HQD: Huang Qi decoction; normal: Hcy and HQD untreated group; Hcy: HUVECs treated with Hcy; HQD10: HUVECs group treated with Hcy and HQD at a concentration of 10 μg/mL; HQD30: HUVECs group treated with Hcy and HQD at a concentration of 30 μg/mL; HQD100: HUVECs group treated with Hcy and HQD at a concentration of 100 μg/mL; tempol: HUVECs group treated with Hcy and tempol; and apocynin: HUVECs group treated with Hcy and apocynin. , , and versus the Hcy group.
