2. 1 months after treatment with high dose glucocorticoid (> 1 mg/kg/d).

3. Serious complications: heart failure (= New York Heart Association(NYHA) III
grade), renal insufficiency (creatinine clearance rate = 30 ml/min), liver
function insufficiency (serum alanine transaminase or glutamic-pyruvic
transaminaseT > 3 times normal upper limit, or total bilirubin > normal upper
limit)

4. Other serious, progressive or uncontrollable hematological, gastrointestinal,

diseases, such as multiple sclerosis).

5. Known allergies, hyperresponsiveness or IL-2 or its excipients are intolerant.

infections (including tuberculosis) within 3 months before the first use of the
study.

8. Infected with HIV (HIV antibody positive serology) or hepatitis C (Hep C antibody
positive serology). If seropositive, consult a doctor with expertise in the
treatment of HIV or hepatitis C virus infection.

9. There has been any known malignant tumor or history of malignant tumor in the
past 5 years (with the exception of non-melanoma skin cancer, non-melanoma skin
cancer with no sign of recurrence or surgically cured cervical tumor within 3
months of use of the first study preparation).

10. There are uncontrolled mental or emotional disorders, including a history of drug
