Data are expressed as mean ± standard deviation. *P < 0.05 versus T0; #P < 0.05 versus sham group.△Student’s t-test, †RM-ANOVA. MDA: malondialdehyde; SOD: superoxide dismutase; TEAS: transcutaneous electrical acupoint stimulation; RM-ANOVA: repeated measures analysis of variance. T0: before one-lung ventilation; T1: 30 min after one-lung ventilation; T2: 1 h after one-lung ventilation; T3: 10 min after resuming two-lung ventilation.
