The aim of this study was to investigate the key role of nuclear factor E2-related factor 2 (Nrf2) in the treatment of lung injury in sepsis mice by regulating Nrf2/heme oxygenase-1 (HO-1)/high mobility group protein B1 (HMGB1) pathway. 120 male wild type (WT) and 120 Nrf2 knockout (Nrf2-KO) ICR mice were randomly divided into Sham group, H2 control group (Sham+H2 …
Hydrogen attenuates neuroinflammation
Sepsis-associated encephalopathy (SAE) is the cognitive impairment resulting from sepsis and is associated with increased morbidity and mortality. Hydrogen has emerged as a promising therapeutic agent to alleviate SAE. The mechanism, however, remains unclear. This research aimed to determine whether hydrogen alleviates SAE by regulating microglia polarization and whether it is mediated by the mammalian target of rapamycin (mTOR)-autophagy pathway. …
Hydrogen alleviates brain injury and cognitive impairment in sepsis
Sepsis-related encephalopathy (SAE), which causes a series of brain injuries and long-term, potentially irreversible cognitive dysfunction, is closely associated with increased morbidity and mortality. Hydrogen (H2) is a new type of medical gas molecule that has been widely used in the treatment of various diseases in recent years. The aim of the present study was to explore the protective effects …
Hydrogen treatment in polymicrobial sepsis
Sepsis-associated intestinal injury has a higher morbidity and mortality in patients with sepsis, but there is still no effective treatment. Our research team has proven that inhaling 2% hydrogen gas (H2) can effectively improve sepsis and related organ damage, but the specific molecular mechanism of its role is not clear. In this study, isobaric tags for relative and absolute quantitation …
Protective effects of hydrogen gas against sepsis-induced acute lung injury
Lungs are one of the most common target organs of sepsis [1]. Hydrogen gas (H2), which has selective anti-oxidative effects, can be effectively used to treat septic mice. Mitochondrial dysfunction and dynamics play important roles in sepsis-induced organ damage. By using cecal ligation and puncture (CLP), a classic septic model, the study explored the role of 2% H2 treatment in …
Preadministration of hydrogen-rich water protects against sepsis
Despite significant advances in antibiotic therapy and intensive care, sepsis remains the most common cause of death in intensive care units. The authors previously reported that molecular hydrogen (H2) acts as a therapeutic and preventive antioxidant. Here, the authors show that preadministration of H2-dissolved water (HW) suppresses lipopolysaccharide (LPS)-induced endotoxin shock in mice. Drinking HW for 3 days before LPS …
Hydrogen-rich medium ameliorates lipopolysaccharide-induced barrier dysfunction
Gastrointestinal barrier dysfunction is associated with the severity and prognosis of sepsis. Hydrogen gas (H2) can ameliorate multiple organ damage in septic animals. Ras homolog gene family member A (RhoA) and mammalian diaphanous-related formin 1 (mDia1) are important to regulate tight junction (TJ) and adherens junction (AJ), both of which determine the integrity of the intestinal barrier. This study was …
Molecular hydrogen therapy ameliorates organ damage induced by sepsis
Since it was proposed in 2007, molecular hydrogen therapy has been widely concerned and researched. Many animal experiments were carried out in a variety of disease fields, such as cerebral infarction, ischemia reperfusion injury, Parkinson syndrome, type 2 diabetes mellitus, metabolic syndrome, chronic kidney disease, radiation injury, chronic hepatitis, rheumatoid arthritis, stress ulcer, acute sports injuries, mitochondrial and inflammatory disease, …
Hydrogen improves lung function in sepsis
Aquaporin 1(AQP1) and AQP5 have an important role in eliminating extravascular lung water, an increase of which contributes to lung injury in patients with sepsis and its consequent mortality. It has been reported that hydrogen-rich saline (HRS) has protective effects against sepsis-related lung injury. In this study, we hypothesized that the protective effect occurred by preserving the expression of AQP1 …
Hydrogen-rich saline ameliorates acute lung injury
Although hydrogen has been proved to be a novel therapeutic medical gas in several lung injury animal models, it has not been tested yet in acute lung injury (ALI) induced by cecal ligation and puncture (CLP). This study was to investigate the hypothesis that hydrogen could ameliorate CLP-induced lung injury in rats. The experiments exhibited that gas exchange dysfunction and …
