ABSTRACT

Objective:

To explore the influence of rivaroxaban on vascular endothelial function and p38MAPK/NF-κB pathway in the rats with arteriosclerosis obliterans.

Methods:

The rats were divided into the sham operation group,the model group,rivaroxaban low dose group,rivaroxaban medium dose group and rivaroxaban high dose group. The contents of nitric oxide (NO) and endothelin (ET-1) in serum were detected, the number of endothelial cells in serum was studied, and the expression level of p38MAPK, p-p38MAPK and NF-κB were measured.

Results:

Compared with that of the model group, the number of endothelial cells in venous blood of rivaroxaban groups decreased. The content of NO in serum of rivaroxaban groups was significantly higher than that of the model group,and the content of ET-1 was significantly lower than that of the model group(P<0.05). The expression level of p-p38MAPK in arterial vessels of rivaroxaban groups was significantly lower than that of the model group,and the expression level of NF-κB was sig-nificantly higher than that of the model group(P<0.05),and the effects were all in a dose-dependent manner.

Conclusion:

Rivarox-aban can improve vascular endothelial function in the rats with arteriosclerosis obliterans,and the effects may be achieved by modula-ting the p38MAPK / NF-κB pathway.
