(6) Within 6 months before screening, acute complications of diabetes mellitus occurred, such as diabetic ketoacidosis or lactic acidosis, or hypertonic hyperglycemia syndrome or diabetic hyperosmolar coma; (7) The surface area of the target lesion ulcer is reduced by = 30% or increased by 50% = during the introduction period of 1 week; (8) Cellulitis or abscess of the target ulcerated foot; (9) Lactating, pregnant women, or patients who are preparing to become pregnant within half a year; (10) Those who have a history of drug allergies, or allergic constitutions (those who are allergic to more than 2 types of substances); (11) Those who have participated in other clinical trials within 3 months; (12) Those who have situations that the researcher deems inappropriate to participate in the research, such as long-term alcohol dependence or drug abuse problems.
