The Role and Mechanism of Immune Regulation in Acute Lung Injury in Children

Acute Lung Injury Clinical Trial

Official title:
The Role and Mechanism of Immune Regulation in Acute Lung Injury in Children

Clinical Trial Summary

Acute lung injury is a highly prevalent disease in children, posing a serious threat to their health and causing economic burden on society and families. It has received high attention. Blocking the cascade immune inflammatory response that occurs in the respiratory tract and finding key targets for the prevention and treatment of acute lung injury has become an important challenge faced by the medical community. The pathogenesis of acute lung injury is complex, involving the combined action of multiple cells and cytokines in the immune system. Therefore, it is necessary to further study the function of immune cells and specific immune pathogenesis, providing new ideas and theoretical basis for clinical treatment of acute lung injury. The omics technology includes Genomics, Transcriptome, proteomics, metabolomics, etc. Through qualitative and quantitative analysis of changes in low molecular weight molecules or metabolites of biological samples, it provides a new way to find biomarkers and pathogenesis. We plan to study the peripheral blood of children with acute lung injury and healthy children, and use network analysis to screen for differential genes and related enrichment pathways in acute lung injury. We aim to explore the correlation between immune regulation and inflammatory repair in children with acute lung injury, and analyze the regulatory mechanisms between immune cells related to it. Provide assistance for clinical diagnosis and treatment.
