ABSTRACT

Objective To study the protective effect and mechanism of SD rats′liver transplantation reperfusion ischemia‐reper‐fusion injury(IRI) after GW3965 activation of liver X receptor preprocessing .Methods Separated Male SD(Sprague‐Dawley) 70 rats into 3 groups which were sham operation group (SO group ,14 rats) ,orthotopic liver transplantation group (OLT group ,28 rats) ,and GW 3965 preprocessing group(GW 3965 group 28rats) .The levels of serum transaminase ,plasma inflammatory factors (TNF‐α、IL‐1) ,the changes of hepatic pathology and inflammatory factor mRNA ,and the activities as well as its expressions of NF‐κB in hepatic tissue were observed ,after the operation .Results After 6 and 24 hours perfusion ,the levels of plasma inflammatory factors was expression ,serum transaminase ,the liver pathological injury degree and the activities as well as its expressions of NF‐κB in OLT group and GW3965 group were higher than those in SO group .While after reperfusion for 6 and 24 hours ,the levels of ser‐um transaminase ,plasma inflammatory factors expression ,the liver pathological injury degree ,inflammatory factor and the activities as well as its expressions of NF‐κB in GW3965 group were much lower than those in OLT group ,there were obvious differences (P<0 .05) .Conclusion After GW3965 activation of liver X receptor preprocessing ,the activities of NF‐κB and the emerging of downstream inflammatory mediator factors are reduced effectively and protect the liver after the ischemia reperfusion .
