研究目的:

1.验证脓毒症高炎症亚表型开源AI工具在中国ARDS队列中的适用性与分布特征,能否准确、稳定地识别出具有相似生物学特征的ARDS高炎症亚型。 2.验证脓毒症高炎症亚表型开源AI工具分类的的高炎症亚型在在中国人群中是否仍是死亡风险的强有力预测因子?评估该高炎症亚表型对患者关键临床结局(如28天/60天死亡率、无呼吸机天数、ICU住院时间)的独立预测价值。 3.探究脓毒症高炎症亚表型开源AI工具能否作为ARDS预测性生物标志物,成功富集出对糖皮质激素和右美托咪定有治疗反应的ARDS人群,即识别出可能从其抗炎治疗中获益的优势亚群。  

Objectives of Study:

To verify the applicability and distribution characteristics of open-source AI tools for highly inflammatory subphenotypes of sepsis in the Chinese ARDS cohort, and whether they can accurately and stably identify highly inflammatory subtypes of ARDS with similar biological features. 2. Verify whether the high-inflammatory subtypes classified by open-source AI tools for the high-inflammatory subtypes of sepsis remain a strong predictor of death risk in the Chinese population? To evaluate the independent predictive value of this highly inflammatory subphenotype for key clinical outcomes of patients, such as 28-day / 60-day mortality, days without ventilators, and length of stay in the ICU. 3. To explore whether open-source AI tools for the highly inflammatory subphenotype of sepsis can serve as predictive biomarkers for ARDS, and successfully enrich the ARDS population that has responded to glucocorticoids and dexmedetomidine, that is, to identify the dominant subgroups that may benefit from their anti-inflammatory treatment.
