INS and diabetes mellitus: High postprandial blood glucose, poor islet function, use of insulin/insulin analogues or insulin secretagogue, high risk of hypoglycemia, long course of disease, and advanced age diabetes patients generally have high blood glucose fluctuation (9).Current studies have shown that combined with α-glucosidase inhibitors (acarbose) on the basis of sulfonylurea secretrogues, hypoglycemia can be reduced and glucose fluctuation can be significantly improved.
