Study Details
Study Description
Brief 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.

Detailed 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.

|---|---|
| control group Healthy people served as the control group |
|
| experimental group Patients with acute lung injury were treated as the experimental group. |
Diagnostic Test: The lungs causes and extrapulmonary factors
Acute lung injury due to internal and external pulmonary causes can be used as intervention items in this study, and intervention items can be excluded according to inclusion criteria and exclusion criteria.

Outcome Measures
Primary Outcome Measures
- Compare the omics differences of blood samples between the experimental and control groups [one year]
Collected separately in the experimental group and the control group participants' blood as a specimen, It is used to obtain exosomes and perform omics sequencing, to obtain the histopathological differences of exosomes between experimental and control groups, In addition, functional verification of genes or proteins with different changes will be carried out to provide clinical basis for subsequent basic research .
- Compare the omics differences of urine samples between the experimental and control groups [one year]
Collected separately in the experimental group and the control group participants' urine as a specimen, It is used to obtain exosomes and perform omics sequencing, to obtain the histopathological differences of exosomes between experimental and control groups, In addition, functional verification of genes or proteins with different changes will be carried out to provide clinical basis for subsequent basic research .
Secondary Outcome Measures
- Compare the omics differences of alveolar lavage fluid samples between the experimental and control groups [one year]
Collected separately in the experimental group and the control group participants' alveolar lavage fluid as a specimen, It is used to obtain exosomes and perform omics sequencing, to obtain the histopathological differences of exosomes between experimental and control groups, In addition, functional verification of genes or proteins with different changes will be carried out to provide clinical basis for subsequent basic research .
