Outcome Measures

Primary Outcomes (2)

  • Compare the omics differences of blood samples between the experimental and control groups

    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 .

    one year

  • Compare the omics differences of urine samples between the experimental and control groups

    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 .

    one year

Secondary Outcomes (1)

  • Compare the omics differences of alveolar lavage fluid samples between the experimental and control groups

    one year

Study Arms (2)

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

Interventions

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.

Sampling MethodProbability Sample
Study Population

The experimental group was patients with acute lung injury, which was caused by various direct and indirect injury factors of alveolar epithelial cells and capillary endothelial cells, resulting in diffuse pulmonary interstitial and alveolar edema, resulting in acute hypoxic respiratory insufficiency. The control group was healthy subjects.

You may qualify if:

  • Signed informed consent voluntarily;
  • Age: \>18 years old, gender: no restrictions ;
  • Patients with known clinical manifestations of respiratory impairment or new/aggravated respiratory symptoms diagnosed within one week of onset according to the Berlin definition guidelines.
  • Age ≥18 years old (including 18 years old), male and female;
  • Male weight ≥50 kg, female weight ≥45kg, and body mass index (BMI) between 19 and 26(inclusive), BMI= weight (kg)/ height (㎡);
  • No smoking, alcohol addiction, no history of drug abuse;
  • No diabetes, asthma, copd, chronic renal insufficiency and other basic diseases; No history of major diseases or infectious diseases (including hepatitis B, hepatitis C, HIV, syphilis);
  • Those who have not taken drugs recently.

You may not qualify if:

  • Patients with diabetes, chronic renal insufficiency, malignant tumors and other basic diseases;
  • severe malnutrition;
  • Pregnant or lactating women;
  • The researcher judged that he was not suitable to participate in this study.
  • pregnant or lactation women;
  • severe malnutrition;
  • The researcher judged that he was not suitable to participate in this study.
