(1) The endothelial cell layer in the SP group was obviously damaged. The relative gene and protein expression of TRPV1, Kir6.1, SUR2B and eNOS was significantly lower than that in the NP group (P<0.01).
(2) The relative gene and protein expression of TRPV1, Kir6.1, SUR2B and eNOS in the control group were significantly lower than those in the capsaicin group (P<0.01) and were significantly higher than those in the capsazepine group (P<0.01).
