Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages Any age
- All sexes
- No healthy volunteers
- Child, Adult, Older adult
Study population: We started collecting lung tissues and peripheral blood from patients with mechanical ventilation from June 2023. All clinical samples have been collected and tested uniformly. Correlation analysis between KLK8 and age using SPSS 22.0 software will be performed, 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.

- 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.

Questions about this trial
What is this clinical trial studying?
An observational study of Ventilator-Induced Lung Injury, run by Xinhua Hospital, Shanghai Jiao Tong University School of Medicine at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 16 Apr 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Lai Jiang, PhD (13817719616__, jianglaimz@sina.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
KLK8 concentration of lung tissue (time frame: 2023.7.1-2024.7.1). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Apr 2024; AzTrials last refreshed its copy on 8 Nov 2026.
