Clinical Trial Summary

The exosomes in the experimental group and the control group were sequenced to find the difference of the two groups, providing a basis for subsequent basic research.

Description:

This study is an observational study, mainly collected by infection, trauma, burns and other non cardiac causes without any related comprehensive character drug treatment of acute respiratory distress (ARDS) in patients with blood, urine or alveolar lavage fluid specimens, used to extract exosomes for omics sequencing, relevant histomorphic variations in exosomes of this disease were obtained, In addition, functional verification of genes or proteins with different changes will be carried out to provide clinical basis for subsequent basic research.
