Bottom Line: In addition, XMJ treatment increased cell activity and decreased monolayer permeability.The expression levels of intracellular adhesion molecule-1, vascular adhesion molecule-1, interleukin-1 and -6 and nuclear factor-κB decreased, while the expression levels of matrix metalloproteinase-2 and tissue inhibitor of metalloproteinase-2 increased with XMJ administration.Increased levels of nitric oxide (NO), eNOS protein and eNOS gene expression were also observed.

ABSTRACT
The aim of the present study was to evaluate the protective effect of the ultrafiltration extract of Xin Mai Jia (XMJ) on a human umbilical vein endothelial cell (HUVEC) injury model induced by hydrogen peroxide (H2O2), by providing experimental data to investigate the mechanism and efficacy underlying the therapeutic effects on atherosclerosis. HUVECs were first injured by H2O2 and then varying final concentrations of the Chinese herb extract were added. Effects of the XMJ extract on morphology, activity, monolayer permeability, biochemical indicators, cytokines, endothelial nitric oxide synthase (eNOS) protein content and eNOS gene expression in the HUVECs were analyzed. H2O2 significantly promoted HUVEC injury. The XMJ ultrafiltration extract significantly improved the morphological changes in the injured HUVECs. In addition, XMJ treatment increased cell activity and decreased monolayer permeability. The expression levels of intracellular adhesion molecule-1, vascular adhesion molecule-1, interleukin-1 and -6 and nuclear factor-κB decreased, while the expression levels of matrix metalloproteinase-2 and tissue inhibitor of metalloproteinase-2 increased with XMJ administration. Increased levels of nitric oxide (NO), eNOS protein and eNOS gene expression were also observed. Therefore, the XMJ ultrafiltration extract exhibits marked anti-inflammatory effects and antioxidant abilities. These properties significantly inhibited the H2O2-induced injury of HUVECs, which may be associated with the NO-cyclic guanosine monophosphate signaling pathway.

XMJ, Xin Mai Jia; HUVECs, human umbilical vein endothelial cells; NO, nitric oxide; H2O2, hydrogen peroxide.

Mentions: In the high-dose XMJ group, the concentration of NO was 22.58±2.58 μmol/l, while in the model group, the concentration was 11.21±1.11 μmol/l. The increase in NO concentration in the high-dose XMJ group exhibited a statistically significant difference (P<0.05) when compared with the model group. Lovastatin and zhibituo exhibited marked suppressive effects on the decrease in NO concentration in HUVECs induced by H2O2, which revealed statistically significant differences (P<0.05) when compared with the model group. However, the effect of the high-dose XMJ was more significant than that of lovastatin and zhibituo. The suppressive effects of low- and middle-dose XMJ on the H2O2-induced decrease in NO levels in the HUVECs were significantly weaker than that of high-dose XMJ (P<0.05), indicating that the effects were dependent on the dose of XMJ (Fig. 5).
