                在影响及相关机制。方法:以10 μmol/L的兰索拉唑孵育HUVEC不同时间(0、24、48、72、96 h)后,应用qRT⁃PCR及Western blot
                技术检测细胞炎症因子白介素6(interleukin 6,IL⁃6)、细胞间黏附分子⁃1(intercellular adhesion molecule⁃1,ICAM⁃1)和血管细胞

               [Abstract] Objective:This study aims to investigate the effect of proton pump inhibitors on adhesion and inflammation of human
                umbilical vein endothelial cells(HUVEC)and its potential mechanism. Methods:Western blot and qRT⁃PCR were used to detect the
                mRNA and protein expression of interleukin⁃6(IL⁃6),intercellular adhesion molecule⁃1(ICAM⁃1)and vascular cell adhesion molecule⁃
                1(VCAM⁃1)in HUVECs after treating with 10 μmol/L lansoprazole for 0,24,48,72 and 96 h,protein levels of calcineurin(CaN)and
                nuclear factor of activated T cells(NFAT)were evaluated at the same time. In addition,protein levels of NFAT,IL⁃6,ICAM⁃1 and
                VCAM ⁃ 1 were evaluated after treating with lansoprazole,CaN inhibitor FK506,and lansoprazole combined FK506 for the further
                research in mechanism. Results:Lansoprazole could time⁃dependently increase the expression of CaN and nuclear translocation of
                NFAT,and further increase the expression of IL⁃ 6,ICAM⁃1 amd VCAM⁃1. Calcineurin inhibitor could relieve the NFAT nuclear
                translocation and vascular inflammation induced by lansoprazole. Conclusion:Lansoprazole may induce endothelial cell inflammation
                and increase cell adhesion by activating CaN.
