Hemorrhagic shock continues to be a major contributor to trauma-related fatalities globally, posing a significant and intricate pathophysiological challenge. The condition is marked by injury and blood loss, which activate molecular cascades that can quickly become harmful. The inflammatory response exhibits a biphasic pattern, beginning with a hyper-inflammatory phase that transitions into immunosuppression, posing significant obstacles to effective therapeutic interventions. This review article explores the intricate molecular mechanisms driving inflammation in hemorrhagic shock, emphasizing cellular signaling pathways, endothelial dysfunction, and immune activation. We discuss the role of molecular biomarkers in tracking disease progression and stratifying risk, with a focus on markers of endothelial dysfunction and inflammatory mediators as potential prognostic tools. Additionally, we assess therapeutic strategies, spanning traditional approaches like hemostatic resuscitation to advanced immunomodulatory treatments. Despite promising advancements in molecular monitoring and targeted therapies, challenges persist in bridging experimental findings with clinical applications. Future efforts must prioritize understanding the dynamic progression of inflammatory pathways and refining the timing of interventions to improve outcomes in hemorrhagic shock management.
失血性休克仍然是全球创伤相关死亡的主要原因,带来了重大而复杂的病理生理挑战。这种情况以损伤和失血为特征,会激活分子级联反应,这些反应很快就会变得有害。炎症反应呈现双相模式,始于过度炎症阶段,随后转变为免疫抑制,这给有效的治疗干预带来了重大障碍。这篇综述文章探讨了失血性休克中驱动炎症的复杂分子机制,重点关注细胞信号通路、内皮功能障碍和免疫激活。我们讨论了分子生物标志物在追踪疾病进展和分层风险方面的作用,重点关注内皮功能障碍标志物和炎症介质作为潜在的预后工具。此外,我们评估了治疗策略,从止血复苏等传统方法到先进的免疫调节治疗。尽管在分子监测和靶向治疗方面取得了有前景的进展,但在将实验结果与临床应用联系起来方面仍然存在挑战。未来的工作必须优先理解炎症通路的动态进展,并优化干预时机,以改善失血性休克管理的结果。
