Subjects diagnosed UC at least 3 months before screening, and the diagnosis of UC was supported by clinical manifestations and endoscopic evidence, and histopathological reports (Note: if there is no previous report, endoscopic and histopathological examinations can be performed during screening). 4. Those who are moderated to severe active Ulcerative colitis is defined as a modified Mayo score (three scores include rectal bleeding, defecation frequency and endoscopic examination) of 4-9 points (inclusive), and the endoscopic single score = 2 points and rectal bleeding score = 1 point. These data were obtained from subject diary records of rectal bleeding and bowel frequency within the first 10 days of randomization, as well as colonoscopy results determined by blind center readers within the first 10 days of randomization. 5. The subject must be a UC subject undergoing treatment. If any of the following requirements are met, they can be selected and must continue to receive these treatments during the induction period: a. Before screening endoscopy, oral 5-ASA (mesalazine) drugs (such as Mesalazine, Sulfasalazine, olsalazine, balsalazide) with stable therapeutic dose have been received for at least 2 weeks. b. Before endoscopic examination in screening period, oral Corticosteroid with stable treatment dose, such as prednisone = 20 mg/day, Budesonide MMX = 9 mg/day, or Equivalent dose of steroid drug stabilizer has been treated for at least 2 weeks. 6. If subjects have recently stopped taking 5-ASA drugs or Corticosteroid to treat UC, they need to stop taking such drugs for at least 2 weeks before screening endoscopy for Mayo score. 7. Male and female subjects must agree not to participate in the pregnancy process from the beginning of screening to 30 days after the last administration (that is, actively try pregnancy or pregnancy, sperm donation, External fertilization); Female subjects with Fertility or male subjects who did not receive Vasectomy should take at least one of the following effective contraceptive methods: abstinence, surgical sterilization (such as Hysterectomy, bilateral oophorectomy), or continued use of acceptable contraceptive methods such as Intrauterine device, contraceptives, condoms, etc. during the study drug administration and = 30 days after the last drug administration.

The subject has undergone ileostomy, colonostomy, or is known to have symptoms of intestinal stenosis. 5. According to the judgment of the researchers, the subjects currently require or anticipate surgical intervention in UC during the study period. 6. The subject is suspected or diagnosed with Crohn's colitis, undiagnosed type of colitis, ischemic colitis, and radiation induced colitis. 7. Have received at least 3 biological agents related to UC treatment in the past. 8. Used traditional Chinese medicine preparations (such as herbs and traditional Chinese patent medicines and simple preparations) to treat UC or other immune diseases within 4 weeks before randomization. 9. Small molecule targeted drugs (such as upatinib) that have received treatment for UC within the first 5 elimination half-lives of randomization. 10. Within 60 days prior to randomization, have received biological agents (infliximab, adalimumab, golimumab, cetuximab, or vitellizumab), or any other experimental medication (including biological and non biological agents). 11. The subject has a history of any significant lung diseases such as chronic obstructive pulmonary disease, pulmonary fibrosis, asthma, etc; Mild intermittent asthma that does not require routine maintenance treatment is excluded. 12. The subject has a history of retinal macular edema or uveitis within the past year. 13. During the screening visit, one of the following abnormalities was found in the lung function test results (including lung ventilation function and lung exchange function test): maximum forced expiratory volume (FEV1) in 1 second or forced vital capacity (FVC)8%) judged by the researcher, or subjects with diabetes with significant complications, such as retinopathy or nephropathy. 16. Serum measurement during pregnancy, lactation, or screening ß- Human chorionic gonadotropin( ß- HCG) positive. During the screening period, any of the following laboratory test results of the subjects were abnormal: a. Hemoglobin124 µ Mol/L (female),>141 µ Mol/L (male). c. Alanine aminotransferase (ALT), aspartate aminotransferase (AST), bilirubin>2 × Upper limit of normal value (ULN), or direct bilirubin>1.5 × ULN. 18. Has a history of primary or secondary immunodeficiency or is currently suffering from active primary or secondary immunodeficiency. 19.
