Men whose partners are fertile must agree to use effective barrier contraception from the beginning of gonorrhea to 1 year after ct1195e infusion, and should not donate semen or sperm during the entire study period;
women with fertility must be tested negative for serum β human chorionic gonadotropin (β -hcg) at the time of screening and within 48 hours before gonorrhea treatment.

meet the following definitions of refractory or progressive disease:
Definition of refractory: the conventional treatment for more than 6 months is still ineffective, or the disease relapses after remission. Definition of conventional treatment: use of glucocorticoids (more than 1 mg/kg/d) or cyclophosphamide, as well as one or more of the following immunomodulatory drugs: antimalarial drugs, azathioprine, mycophenolate mofetil, methotrexate, leflunomide, tacrolimus, cyclosporine, and biological agents, including yamerol, rituximab, belizumab, etanercept, etc;
According to the definition of progressiveness, 2 of the following three items can be met in the past 1 year (within the past 1 year):
Aggravation of symptoms;

there is active tuberculosis risk during screening: there are signs or symptoms of active tuberculosis judged by the investigator (such as fever, cough, night sweat and weight loss); Records of chest imaging (e.g., chest X-ray, chest CT scan) performed at screening or any time within 6 months before screening showed active tuberculosis.
have previously received car-t cell or other gene modified T cell therapy, or have a history of major organ transplantation (such as heart, lung, kidney, liver) or hematopoietic stem cell / bone marrow transplantation;
have used drugs targeting B cells (such as rituximab) within 3 months before screening;
