Clinical Trial Summary

Objective: Explore the biomarkers related to proliferative diabetic retinopathy by analyzing the protein expression profile changes of plasma exosomes in patients with difference phases of diabetic retinopathy, and investigate potential molecular mechanisms and therapeutic targets. Methods: Enrich exosomes from plasma by column extraction method. NTA, WB and TEM were used to characterize the obtained exosomes, and exosome proteinomics was performed by chromatography⁃mass spectrometry. Corhorts: The study was divided into four groups: a healthy control group, a diabetic without diabetic retinopathy group, a non-proliferative diabetic retinopathy group, and a proliferative diabetic retinopathy group, with 6 cases in each group.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	differential proteins of exosomes	Exosomes were extracted and isolated from plasma, proteomics analysis of proteins in exosomes was performed to compare the number of types of changes in exosomal proteins of the four groups and to identify proteins that were up-regulated and/or down-regulated, and the relationship between the proteins and diabetic retinopathy was then analysed to look for possible mechanisms and therapeutic targets for diabetic retinopathy.
