Objective To investigate protective effects of electroacupuncture on injury of lipid peroxidation-induced by liver ischemia in rats with sepsis.Methods Forty-eight male SD rats were subjected to sepsis by cecal ligation and puncture （CLP）,and were randomly divided into a sham operation group （group A）,a CLP model group （group B）,a CLP model plus electroacupuncture （EA） at Zúsānlǐ （足三里 ST 36） group （group C）,a CLP model plus electroacupuncture at a sham acupoint group （group D）,a CLP model with vagotomy group （group E） and a CLP model plus electroacupuncture group after vagotomy （group F）,with 8 rats in each group.CLP was performed after abdominal vagotomy in group E and group F.EA （2 mA,2/100 Hz） was applied at bilateral ＂Zúsānlǐ＂ （足三里 ST 36） in group C and group F,and at sham acupoints in group D,respectively,for 1 hour.The hepatic blood flow （HBF） was detected by a laser-doppler flowmetry at 6 hours after CLP.The activity of plasma alanine transarninase （ALT） was determined;contents of hepatic malondialdehyde （MDA）,activity of xanthine oxidase （XOD） and the rate of water content in the hepati tissue were assessed,respectively.Results Hepatic blood flow was （56.97±11.95） U in group C,which was significantly lower than （80.12± 19.57） U shown in group A,but higher than （42.61±10.97） U in group B,（44.53±9.23） U in group D,（30.05 ±4.46） U in group E and （30.46±6.38） U in group F （all P0.05） at 6 hours after CLP.Meanwhile,the levels of MDA,XOD,ALT and hepatic water content in group C were all significantly higher than those in group A,but lower than those in the other four groups （all P0.05）.The levels of MDA,XOD,ALT and hepatic water content in group E and group F were all significantly higher than those in group D （all P0.05）,while their hepatic blood flow were lower than that in group D （both P0.05）,and no significant differences were found in all the indices mentioned above between group
