This study focuses on potential use molecular dihydrogen (H2) inhalation as an adjunctive treatment COVID-19. H2 therapy shows promise inhibiting intracellular signaling pathways associated with inflammation, particularly when administered early conjunction nasal oxygen therapy. phase I study, characterized open-label, prospective, monocentric, and single ascending-dose design, seeks to assess safety tolerability procedure individuals confirmed SARS-CoV-2 infection. Employing 3 + includes three exposure durations (target durations): 1 day (D1), days (D2), 6 (D3). We concluded that maximum tolerated duration is at least days. Every patient showed clinical improvement excellent tolerance To best our knowledge, this trial first establish inhaling mixture (3.6%) N2 (96.4%) hospitalized COVID-19 patients. original device method employed ensure absence explosion risk. encouraging outcomes observed 12 patients included justify further exploration through larger, controlled trials. registered ClinicalTrials.gov NCT04633980.

Acute myocardial infarction (AMI) is a deadly cardiovascular disease with no effective solution except for percutaneous coronary intervention and artery bypass grafting. Inflammation apoptosis of the injured myocardium after revascularization seriously affect prognosis. Hydrogen possesses anti-inflammatory, anti-oxidative, anti-apoptotic effects may become new treatment AMI. This study explored specific mechanism by which hydrogen operates during AMI treatment. Thirty Sprague-Dawley rats were randomly divided into three groups: control, (MI), + (MI+H2), each containing 10 rats. The MI rat model was established ligation left anterior descending branch. MI+H2 group received 2% inhalation 3 h/Bid. Myocardial infarct size evaluated using triphenyl tetrazolium chloride staining. Transmission electron microscopy showed reduced mitochondrial damage compared group.
