MiR-26a-5p inhibition expression level inhibits the anti-oxidative stress effect of post-ischemic treatment with sevoflurane. A: Influence of antamiR-26a-5p+sevoflurane on the SOD content in myocardial tissue of rats (n = 7). B: Influence of antamiR-26a-5p + sevoflurane on CAT content in rat myocardial tissue (n = 7). C: Influence of antamiR-26a-5p+sevoflurane on GSH-Px content in rat myocardial tissue (n = 7). D: Influence of antamiR-26a-5p + sevoflurane on MDA content in rat myocardial tissue (n = 7). E: Influence of antamiR-26a-5p+sevoflurane on ROS content in rat myocardial tissue (n = 7). ** represents sham group V.S. I/R model group; ## represents I/R model group V.S. sevoflurane group P<0.01; and represents sevoflurane group V.S. sevoflurane+antamiR-26a-5p group P<0.01.
