Clinical Trial Summary

Tryptase, TLR4, and anti-NR2A antibodies were measured in serum, cerebrospinal fluid, and subjects and other markers to assess their relevance to disease activity, aiming to find new therapeutic targets,Timely intervention to improve the prognosis of SLE and improve the quality of life of patients with SLE.

Description:

This study is a prospective cohort study: it is proposed to be divided into 3 groups, namely healthy control group and SLE group, NPSLE epilepsy group; Fifteen cases were included in each group, with the consent of the subjects and signed to know Consent form, record all subjects' clinical and laboratory test data, and test subjects' blood. Markers such as cerebrospinal fluid tryptase, TLR4 and anti-NR2A antibodies, follow-up 2 year, the patient's disease activity is evaluated every year, the change of indicators is dynamically observed, and statistical points are made divide.
