Biological: Detection of cytof in peripheral PBMC
Registration Number
NCT05518409
Lead Sponsor
First Affiliated Hospital of Zhejiang University
Brief Summary

The subject uses cytof to analyze PBMC of sporadic AD and DLB, which is used to reveal the differences in immune characteristics of the two diseases at the single-cell level, build immune models for specific diseases, and define these two neurodegenerative diseases with high precision from the level of molecular immunity. To provide basis for further study of the immunohistochemical differences between the two diseases, and provide objective support for clinical diagnosis and differential diagnosis.

Primary Outcome Measures
NameTimeMethod
Immunerepertorie1 year

The immune cells were drawn into immunoreceptor by mass cytometry (cytof) technology. Immunerepertorie is used for the classification of immune cells. According to the proportion of various immune cell subtypes and biomarkers in all cells, it is used to find the difference between immune cell subtypes and biomarkers in different diseases. Scoring frame: 0-1. The higher the score, the greater the proportion of this subtype or biomarker.

immunological Elastic-Net (iEN) model1 year

The immunological Elastic-Net (iEN), which incorporates immunological knowledge directly into the predictive models. The ROC curve output by the model is plotted with specificity as the abscissa and sensitivity as the ordinate, and the AUC (area under the curve) value is calculated. The AUC value was used to evaluate the authenticity of the IEN model. Score frame: 0.5-1. A higher value indicates that the model is closer to the real situation.

Secondary Outcome Measures
NameTimeMethod
Mini-mental State Examination(MMSE)1 year

MMSE was used to evaluate the degree of intellectual status and cognitive impairment. Score frame: 0 \~ 30. The lower the score, the more severe the cognitive impairment.
