miR-26a-5p inhibition expression level inhibits the myocardial protective effect of sevoflurane after ischemia. A: The effect of miR-26a-5p inhibition expression level on rat myocardial tissue morphology in the sevoflurane group (n = 3). B: The impact of miR-26a-5p inhibition expression level on the content of myocardial tri-enzymes in rat myocardial tissue in the sevoflurane group (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.
