7. Acute complications of diabetes such as diabetic ketoacidosis, hyperosmolar nonketotic diabetic coma, lactic acidosis, and hypoglycemic coma occurred within 6 months before the screening period; and there were complications requiring acute treatment at screening visit 1, including but not limited to: proliferative vitreoretinopathy, maculopathy, painful diabetic peripheral neuropathy, and diabetic foot (ulcer, infection);

Hepatitis C (if the HCV antibody test is positive, HCV RNA testing is required. If the HCV antibody test is positive and the HCV RNA result is positive, hepatitis C patients must be excluded); patients with active syphilis (if the Treponema pallidum antibody test is positive, antibody titer testing is required, and patients with active syphilis are excluded according to the center's testing standards); HIV-positive patients, whose condition is in a stable stage, can be included by the researcher based on the comprehensive performance of the subjects;
