Methods at a glance
Male C57BL/6 mice and cultured neonatal rat cardiomyocytes
50 mice divided into five groups, 10/group; five/group were used for infarct staining and five/group for stored-tissue analyses
30 minutes of ischemia followed by 24 hours of reperfusion; multiple cellular schedules
0.6 mmol/L hydrogen-rich saline, 10 mL/kg intraperitoneally 5 minutes before reperfusion; cells received 0.6 mmol/L H₂-rich medium
H₂ dissolved in saline or culture medium — H₂ only, not Brown’s gas and not inhalation.
0.6 mmol/L dissolved H₂; saline was saturated for 6 hours at 0.4 MPa and verified by gas chromatography.
Not applicable — saline and culture medium, not gas inhalation.
No O₂ was co-delivered as part of the intervention.
Ischemia-reperfusion and hypoxia-reoxygenation controls plus pathway-manipulation groups
Outcomes and reported result
Infarct size, cardiac function, apoptosis, cell viability and miR-124-3p/calpain1 pathway
The article reports improved cardiac and cell-injury outcomes with H₂-rich saline and attenuation of the effect when the proposed pathway was manipulated.
The complete open-access article was checked for preparation, dose, animal allocation, intervention timing, figures, funding and conflicts.
A reported association, difference or mechanism is not automatically a clinical benefit. Null findings, outcome type, study design and precision all matter.
Cautions and applicability
Preclinical mouse and cell work, many pathway experiments and no human participants. The article declares no conflicts.
Experimental myocardial ischemia-reperfusion and cultured cardiomyocytes, not patients with myocardial infarction.

No single-study GRADE certainty rating is assigned. Certainty is assessed by important outcome across a complete eligible evidence set, not by attaching a final grade to one source.
