研究目的:

1. 主要目的:在已有的工作基础上,利用深度的学习技术整合生物大数据、新算法及可解释工具,以脓毒症患者的治疗参数、血液指标、尿液指标为数据,提出基于机器学习的亚型分类模型,挖掘不同亚群脓毒症患者的生物标志物。阐明影响亚型差异可能的归因,探索低分子肝素在脓毒症患者治疗过程中的时间效应,以期构建精准、智能、安全、有效的脓毒症患者亚型诊断方法和抗凝治疗策略。 2. 次要目的:发现其他治疗因素对脓毒症不同亚群转归的干预作用及机制  

Objectives of Study:

1. Main objective Based on existing work utilize deep learning techniques to integrate biological big data new algorithms and interpretable tools Using treatment parameters blood indicators and urine indicators of sepsis patients as data propose a machine learning-based subtype classification model to discover biomarkers for different subgroups of sepsis patients Elucidate the factors affecting subtype differences explore the time effect of low molecular weight heparin in the treatment of sepsis patients with the aim of developing precise intelligent safe and effective diagnostic methods and anticoagulant treatment strategies for sepsis patient subtypes 2. Secondary objective Investigate the intervention effects and mechanisms of other treatment factors on the outcomes of different subgroups of sepsis patient
