What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Control | Chinese Han people undergoing coronary angiography in Qilu Hospital in corresponding period whose coronary arteries narrowing less than 50 percent. | |
| Aortic dissection | Chinese Han people diagnosed with aortic dissection in Qilu Hospital |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of patients with different ALDH2 genotype
DNA was extracted from venous blood;genomic DNA underwent PCR amplification; finally, PCR products were purified and directly sequenced by Invitrogen Corp or Biosune Corp.Then ALDH2 genotype was distinguished depend on a G-to-A missense mutation on exon 12 of ALDH2 gene.
Measured: 1-30 days after samples collected
Secondary outcomes (2)
Concentration of inflammatory factors in blood and aortic specimen
Concentration of 4-HNE、MMP-2、MMP-9 detected by elisa kit、IHC or western blot in relevant specimen.
Measured: 1-30 days after samples collected
ALDH2 activity
Activity of ALDH2 was detected in blood and aortic specimen depend on its reducibility of NAD+
Measured: 1-30 days after samples collected

Questions about this trial
What is this clinical trial studying?
An observational study of Aortic Dissection, run by Qilu Hospital of Shandong University 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 1 inclusion and 3 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: status not confirmed, as of the sponsor's last update on 5 Feb 2019. 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.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of patients with different ALDH2 genotype (time frame: 1-30 days after samples collected). 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 5 Feb 2019.
