Clinical Trial Summary

The goal of this observational study is to profile the circulating immunological traits of patients with traumatic lung injury (TLI) and inhalation injury (ILI),providing a new direction for the depth research of the pathogenesis, and providing new immune-related targets for diagnosis of the severity of lung injury and treatment. The investigators performed scRNA-seq of neutrophil and peripheral blood mononuclear cells (PBMCs) from 10 ml fresh circulating blood from 3 patients with TLI and 3 patients with ILI at longitudinal timepoints,as well as peripheral blood from 3 health controls(HCs).


Description:

The investigators performed single-cell transcriptomic sequencing (BD Rhapsody) on neutrophil and PBMCs extracted from the fresh circulating blood from 3 patients with TLI and 3 patients with ILI at longitudinal timepoints,as well as peripheral blood from 3 health controls(HCs). Three time points are picked by clinical conditions of patients with TLI or ILI: day 1 post hospital admission, day 3 post hospital and the day before discharged which matched to acute stage,progressive stage and convalescence.

Eligibility Inclusion Criteria: 1. Lung injury caused by burn trauma is confirmed, and the patient is hospitalized within 24 hours after burn or trauma (the clinician can make a definite diagnosis of lung injury based on the comprehensive judgment of the patient's etiology, history, clinical manifestations, blood gas analysis, laboratory tests and imaging); 2. Patients with inhalation injury caused by head, face and neck burns or inhalation injury combined with multiple body burns < 30%; 3. Patients with simple inhalation injury; 4. The normal control group should have no smoking history and be normal population; 5. According to the provisions of Good Clinical Practice(GCP), the informed consent has been obtained and the informed consent has been signed to volunteer for the test. Exclusion Criteria: 1. Basic pulmonary diseases like chronic obstructive pulmonary disease (COPD), asthma and et al; 2. Severe organ dysfunction; 3. Autoimmune diseases; 4. Tumor; 5. Severe infection; 6. Pregnant or nursing women; 7. Fatal or life-threatening events caused by trauma; 8. Any history which may interfere the results or increase the risk of patients judged by researchers.
