研究目的: |
本研究旨在通过回顾性分析,系统观察LP患儿病程中De Ritis比值的动态变化规律,并深入探讨其与患儿病情严重程度的相关性。期望本研究能为儿童LP的病情评估体系提供新的实验室依据,并为临床预后判断与干预时机选择提供参考。 |

|
Objectives of Study: |
This study aims to systematically observe the dynamic changes in the De Ritis ratio during the disease course in children with LP through a retrospective analysis, and to deeply explore its correlation with the severity of the illness in these patients. It is expected that this study can provide a new laboratory basis for the disease assessment system of LP in children and offer references for clinical prognosis judgment and the selection of intervention timing. |
