Down‐regulation of miR‐124‐3p abolishes heart protective effect of hydrogen‐rich saline (HRS) induced by hypoxia/reoxygenation (H/R) injury. (A) Expression of miR‐124‐3p decreased both in vivo and in vitro after being treated with miR‐124‐3p inhibitor. (B) Cell viability of neonatal rat cardiomyocytes (NRCMs) after H/R injury was measured. (C) Lactate dehydrogenase (LDH) activity of NRCM culture medium after H/R injury was measured. (D) Caspase‐3 activity of NRCMs after H/R injury was measured. *P < 0.05, **P < 0.01, and ***P < 0.001.
