Abstract (original English)

Currently, the treatment of septic myopathy presents significant challenges with implications for increased mortality rates and prolonged hospitalizations. Effective therapeutic strategies for septic myopathy remain elusive, highlighting an urgent need for novel therapeutic approaches. High-mobility group box 1 (HMGB1) is a conserved nonhistone nuclear protein that is released passively from deceased cells or actively secreted by activated immune cells, influencing both infectious and noninfectious inflammatory responses. Studies have indicated that HMGB1 likely plays a pivotal role in the pathogenesis of septic myopathy by crucial pathways associated with muscle atrophy and contributing to muscle regeneration under certain conditions. This review aims to summarize the possible mechanisms of HMGB1 in muscle atrophy and its potential in muscle regeneration, providing a theoretical basis for HMGB1 treatment of septic myopathy. Research shows that the dual role of HMGB1 is related to its specific forms, which are influenced to varying degrees by environmental factors. HMGB1 is a key participant in septic muscle atrophy, whereas HMGB1 shows therapeutic potential in muscle regeneration. One key mechanism by which HMGB1 contributes to septic muscle atrophy is through the exacerbation of inflammation. HMGB1 can amplify the inflammatory response by promoting the release of pro-inflamma
