Thus, developing safe and effective preparations for hangover relief, liver protection, and brain function regulation is of great practical significance. In this study, we fabricated a thermosensitive chitosan (CS)\u2013sea cucumber peptide (SCP) hydrogel (CS\u2013SCP gel) loaded with SCP using NaHCO3 as a crosslinker and characterized its properties. Kunming mouse models of anti-intoxication and acute alcohol-induced liver and brain injuries were established. The anti-intoxication and organ-protective effects of the CS\u2013SCP gel were comprehensively evaluated through behavioral observation, liver histopathology, and biochemical assays of serum and liver, kidney, and brain tissues. The CS\u2013SCP gel exhibited a phase transition temperature of 35.7 \u00b0C, a water absorption rate of 1015.47%, and a cumulative peptide release of 74.83% within 330 min. In mice, it prolonged the latency to drunkenness; shortened alcohol-induced sleep and sobering time; reduced blood ethanol, transaminase, and lipid levels; upregulated hepatic antioxidant enzymes; downregulated pro-inflammatory cytokines, and alleviated lipid peroxidation. It also enhanced brain antioxidant capacity, suppressed cerebral inflammatory cytokines, and maintained cholinergic neurotransmitter homeostasis. Collectively, with sustained release, CS\u2013SCP gel is expected to prolong the pharmacological action of SCP, enhance therapeutic efficacy, and protect against alcohol-induced liver and brain injury through the regulation of oxidative stress and attenuation of inflammation.<\/jats:p>","DOI":"10.3390\/md24090294","type":"journal-article","created":{"date-parts":[[2026,8,24]],"date-time":"2026-08-24T09:20:02Z","timestamp":1787563202000},"page":"294","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Preparation of a Thermosensitive Chitosan\u2013Sea Cucumber Peptide Hydrogel and Its Alleviating Effect on Acute Alcohol-Induced Dual Liver and Brain Injury in Mice"],"prefix":"10.3390","volume":"24","author":[{"given":"Jiaqi","family":"Guo","sequence":"first","affiliation":[{"name":"College of Chemistry and Environment, Guangdong Ocean University, Zhanjiang 524088, China"},{"name":"Faculty of Medicine, Macao University of Science and Technology, Macao 999078, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Songzhi","family":"Kong","sequence":"additional","affiliation":[{"name":"College of Chemistry and Environment, Guangdong Ocean University, Zhanjiang 524088, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chen","family":"Chen","sequence":"additional","affiliation":[{"name":"College of Chemistry and Environment, Guangdong Ocean University, Zhanjiang 524088, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-2797-3791","authenticated-orcid":false,"given":"Guiping","family":"Lu","sequence":"additional","affiliation":[{"name":"College of Chemistry and Environment, Guangdong Ocean University, Zhanjiang 524088, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zirui","family":"Li","sequence":"additional","affiliation":[{"name":"College of Chemistry and Environment, Guangdong Ocean University, Zhanjiang 524088, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinhui","family":"Chen","sequence":"additional","affiliation":[{"name":"College of Chemistry and Environment, Guangdong Ocean University, Zhanjiang 524088, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meiyin","family":"Liang","sequence":"additional","affiliation":[{"name":"College of Chemistry and Environment, Guangdong Ocean University, Zhanjiang 524088, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,23]]},"reference":[{"key":"ref_1","unstructured":"World Health Organization (2024).
