摘要: Factor Xa inhibitor is used for preventing venous thromboembolism (VTE) in adult patients receiving orthopedic operation. However, the role of factor inhibitor, rivaroxaban, angiogenesis still unknown. Streptozotocin (STZ)–induced diabetic mice with model hind-limb ischemia, were divided into non-diabetic control, and low- high-dose rivaroxaban treatment groups, order to evaluate effect angiogenesis. Doppler perfusion imaging showed that blood flow recovery was significantly increased, more capillary density occurred group. In vitro studies, human endothelial progenitor cells (EPCs) treated had significant functional improvement migration senescence under hyperglycemic conditions. Rivaroxaban also increased nitric oxide synthase (eNOS) as well vascular growth (VEGF) expressions hyperglycemia-stimulated EPCs. promoted vessel formation improved cell function These effects may be associated enhancement expression eNOS VEGF.
