Mechanism Study of Ventilator-Induced Lung Injury in Elderly People.
- Conditions
- Ventilator-Induced Lung Injury
- Interventions
- Procedure: mechanical ventilation
- Registration Number
- NCT06367946
- Brief Summary
1. We collect lung tissues from patients with different ages and confirm that KLK8 expression is positively correlated with age.
2. We collect peripheral blood from patients with different ages and duration of mechanical ventilation to explore the correlation between the degree of endothelial/epithelial damage, age and duration of mechanical ventilation.
- Detailed Description
1. We collect lung tissues from patients with different ages and confirm that KLK8 expression is positively correlated with age. All clinical samples have been collected and tested uniformly. Correlation analysis between KLK8 and age will be performed by using Statistical Package for the Social Sciences (SPSS) 22.0 software, and P\<0.05 indicates a statistically significant difference. The obtained clinical data should be recorded on survey forms, and researchers should verify patient information by recording basic information such as age and gender.
2. We collect peripheral blood from patients with different ages and duration of mechanical ventilation to explore the correlation between the degree of endothelial/epithelial damage, age and duration of mechanical ventilation. All clinical samples have been collected and tested uniformly. Correlation analysis between endothelial/epithelial damage index, age and duration of mechanical ventilation will be performed by using SPSS 22.0 software, and P\<0.05 indicates a statistically significant difference. The obtained clinical data should be recorded on survey forms, and researchers should verify patient information by recording basic information such as age and gender.
