ABSTRACT
Chemotherapy is one of the major strategies for cancer treatment. Several antineoplastic drugs including vinorelbine (VRB) are commonly intravenously infused and liable to cause serious phlebitis. The therapeutic drugs for preventing this complication are limited. In this study, the mechanism of baicalein (BCN) was investigated on VRB-induced phlebitis in vivo and vascular endothelial cell injury in vitro. Treatment with BCN obviously attenuated vascular endothelial cell loss, edema, inflammatory cell infiltration and blood clots, and reduced the serum levels of TNF-α, IL-1ß, IL-6 and ICAM-1 in the rabbit model of phlebitis induced by intravenous injection of VRB compared with vehicle. Further tests in vitro demonstrated that BCN lessened VRB-induced endothelial cell apoptosis, decreased intracellular ROS levels, suppressed phosphorylation of p38 and eventually inhibited activation of NF-κB signaling pathway. And these effects could be reversed by p38 agonist P79350. These results suggested that BCN exerted the protective effects against VRB-induced endothelial disruption in the rabbit model of phlebitis via inhibition of intracellular ROS generation and inactivation of p38/NF-κB pathway, leading to the decreased production of pro-inflammatory cytokines. Thus, BCN could be used as a potential agent for the treatment of phlebitis.
