研究目的:

儿童脓毒症是全球儿童健康面临的重大公共卫生挑战,每年约影响300万新生儿和120万儿童,死亡率高达11-19%。尽管医疗诊治水平不断提高,儿童脓毒症死亡率仍居高不下,位列14岁以下儿童死亡原因第2位。近年来,越来越多研究揭示肠道微生物群在脓毒症发病机制和预后中发挥关键作用。本项目拟通过多组学方法深入探索儿童脓毒症肠道菌群生态失调的动态变化及其免疫调节机制。项目将结合多中心数据,通过粪便宏基因组测序和代谢组学方法,系统性解析儿童脓毒症肠道菌群动态变化,重点关注关键细菌及其代谢产物在免疫调节中的作用机制,探索其对免疫细胞、炎症反应和肠道屏障完整性的影响。通过多尺度、多维度分析,旨在揭示肠道菌群失衡与脓毒症发生发展的内在联系。 本研究有望提供更精确的特征菌群及代谢物特征,为儿童脓毒症的早期预警、精准诊断和个性化治疗提供新的理论基础和潜在干预策略。  

Objectives of Study:

Pediatric sepsis remains a critical global public health challenge, affecting approximately 3 million neonates and 1.2 million children annually, with a mortality rate as high as 11–19%. Despite advances in medical care, sepsis-related mortality remains persistently high, ranking as the second leading cause of death in children under 14 years of age. Recent studies have increasingly highlighted the pivotal role of gut microbiota in the pathogenesis and prognosis of sepsis. This project aims to employ a multi-omics approach to investigate the dynamic changes in gut microbial dysbiosis and its immunomodulatory mechanisms in pediatric sepsis. Leveraging multicenter clinical data, we will perform fecal metagenomic sequencing and metabolomic profiling to systematically characterize gut microbiota dynamics in septic children, with a focus on key bacterial species and their metabolic byproducts in immune regulation. The study will further explore their effects on immune cells, inflammatory responses, and intestinal barrier integrity. Through multi-scale and multi-dimensional analyses, this research seeks to elucidate the intrinsic relationship between gut microbiota imbalance and sepsis progression. The findings are expected to identify precise microbial and metabolic signatures, providing a novel theoretical foundation for early warning, accurate diagnosis, and personalized treatment strategies for pediatric sepsis.
