Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
2. On baseline, 6 months after treatment and 24 months after treatment, the AAV patients will accomplish the Birming-ham vasculitis activity score(BVAS) besides DTI；
3. The new serum biomarkers of AAV associated peripheral neuropathy will be measured by ELISA； (4) Another cohort with 50 patients with AAV associated peripheral neuropathy who were evaluated by traditional methods (electromyogram) and compared to the patients cohort that evaluated using DTI by cost-benefit analysis
