Clinical Study of Cord Blood Mononuclear Cells on Treatment of Hormone-resistant or Hormone-dependent Ulcerative Colitis

Clinical Study of Cord Blood Mononuclear Cells on Treatment of Hormone-resistant or Hormone-dependent Ulcerative Colitis

This study conducted a systematic clinical observation of the clinical efficacy of UCB-MNCs in the treatment of hormone-resistant or hormone-dependent ulcerative colitis, in order to observe its clinical safety and efficacy.

This study adopts a randomized and controlled clinical research design. Patients are randomly divided into conventional treatment control group and UCB-MNCs treatment test group. The control group is given conventional treatment: prednisone combined azathioprine or adalimumab; the test group is given conventional treatment combined UCB-MNCs treatment, follow-up observations were carried out, in order to observe the clinical efficacy and safety of UCB-MNCs in the treatment of hormone resistance or hormone-dependent ulcerative colitis.
