ABSTRACT
Objective To investigate the mechanism of PBEF in pulmonary vascular endothelial permeability increasing after car-diopulmonory bypass ,in order to provide the basis for a better lung protective measures during cardiopulmonary bypass .Methods Animal models were established ,group Athe rats were transfected with the lentiviral AD-PBEFshRNA ;group Bthe rats were took 30 min deep hypothermic circulatory arrest ;group Cthe rats were took 30 min deep hypothermic circulatory arrest ,then trans-fected with the lentiviral AD-PBEFshRNA ;control groupthe rats were anesthetized and established CPB tube ,without CPB by-pass .Lung tissue was detected with Western blotting and ELISA .Results PBEF ,phosphorylation of P38MAPK ,ERK ,MLC ,VE-cadherin ,FAK in group C had significant difference with group A ,B and the control group(P<0 .05) .VEGF ,MMP2 ,MMP9 ,W/D in group C had significant difference with group A ,B and the control group(P<0 .05) .The pathological results showed that rat lung tissue of the control group was normal ,while in group C ,it had severe pathological damage ,the pathological damage degree in group A ,B reduced compared to group C .Conclusion PBEF can through MAPK/PI3K-Akt/VEGF signaling pathway ,increase pulmonary vascular endothelial permeability .
