Sevoflurane alleviates intestinal ischemia-reperfusion injury in aged mice.
Sevoflurane is a widely used inhalation anesthetic during the perioperative period. Recent studies have suggested that sevoflurane has an enteroprotective effect, but its mechanism is unclear. To explore the mechanism of sevoflurane in intestinal ischemia‒reperfusion injury, an intestinal ischemia‒reperfusion injury mouse model was established. First, intestinal ischemia‒reperfusion injury was compared between aged and young mice. The results showed that intestinal ischemia‒reperfusion injury caused pathological intestinal injury and disrupted the intestinal mucosal barrier. The aged mice had more severe intestinal ischemia‒reperfusion injury than the young mice and therefore had a lower survival rate. The aged mice subsequently received sevoflurane via inhalation. Sevoflurane alleviated the pathological injury to the intestinal mucosa and repaired the function of the intestinal mucosal barrier in aged mice, thus increasing the level of intestinal mucosal hypoxia-inducible factor-1α and improving the survival rate of aged mice. However, preoperative administration of the hypoxia-inducible factor-1α inhibitor BAY87-2243 could counteract the enteroprotective effect of sevoflurane and lower the expression level of heme oxygenase-1, a downstream antioxidant enzyme of hypoxia-inducible factor-1α. Our findings suggest that sevoflurane alleviates intestinal ischemia‒reperfusion injury in aged mice by repairing the intestinal mucosal barrier through the activation of hypoxia-inducible factor-1α/heme oxygenase-1, providing a new target for the treatment of intestinal ischemia‒reperfusion injury in aged mice.
期刊介绍:
Medical Gas Research is an open access journal which publishes basic, translational, and clinical research focusing on the neurobiology as well as multidisciplinary aspects of medical gas research and their applications to related disorders. The journal covers all areas of medical gas research, but also has several special sections. Authors can submit directly to these sections, whose peer-review process is overseen by our distinguished Section Editors: Inert gases - Edited by Xuejun Sun and Mark Coburn, Gasotransmitters - Edited by Atsunori Nakao and John Calvert, Oxygen and diving medicine - Edited by Daniel Rossignol and Ke Jian Liu, Anesthetic gases - Edited by Richard Applegate and Zhongcong Xie, Medical gas in other fields of biology - Edited by John Zhang. Medical gas is a large family including oxygen, hydrogen, carbon monoxide, carbon dioxide, nitrogen, xenon, hydrogen sulfide, nitrous oxide, carbon disulfide, argon, helium and other noble gases. These medical gases are used in multiple fields of clinical practice and basic science research including anesthesiology, hyperbaric oxygen medicine, diving medicine, internal medicine, emergency medicine, surgery, and many basic sciences disciplines such as physiology, pharmacology, biochemistry, microbiology and neurosciences. Due to the unique nature of medical gas practice, Medical Gas Research will serve as an information platform for educational and technological advances in the field of medical gas.
