\. Those who voluntarily participated in this trial and provided informed consent;

Exclusion Criteria11

\. Allergic to pretreatment measures
\. received any containing ATG/ALG such IST、alemtuzumab、high-dose cyclophosphamide (≥ 45mg/kg/day) , received CsA treatment within 6 months, or used thrombopoietin receptor (tpo-r) agonists in the past;

\. Patients with malignant tumor;
\. People with other genetic diseases；
\. After receiving CD7 car-t treatment, patients who were unable to accept subsequent kidney transplantation due to severe infection or poor amplification of car-t in vivo.
\. Any situation that researchers believe may increase the risk to the subjects or interfere with the trial results.
