The Value of Serum MicroRNA-21-5p and LncRNAgadd7 Expression Levels in Predicting the Severity and Prognosis of ARDS ( Acute Respiratory Distress Syndrome )

The Value of Serum MicroRNA-21-5p and LncRNAgadd7 Expression Levels in Predicting the Severity and Prognosis of ARDS ( Acute Respiratory Distress Syndrome )

By measuring the expression levels of MicroRNA-21-5p (miR-21-5p) and LncRNAgadd7 in the peripheral blood of ARDS patients, the study aims to explore the correlation between these levels and the severity and prognosis of ARDS.

4. Signed informed consent.

Exclusion Criteria:

1. Immunosuppressed patients: including those on immunosuppressive drugs, history of stem cell transplantation, etc.;
2. Patients with malignant tumors;
3. Pregnant women;
