Insulin therapy is the mainstream glucose-lowering program for hospital glucose management. Intelligent insulin dose calculation software based on fingertip glucose monitoring is born in response to the situation. A new generation of continuous blood glucose monitoring technology compared with traditional monitoring technology provides more abundant blood sugar change information.The development of the continuous glucose monitoring technology espcially in blood sugar change trend arrow information, the intelligent insulin dose adjustment sequence based on WeChat program is developed. We plan to carry out a randomized controlled study on patients receiving insulin therapy, in which the insulin dose is adjusted according to the information of four blood glucose monitoring points (before meals and before bed), and randomly divided into two groups, one group is adjusted according to the experience of clinicians, the other group is adjusted according to Wechat program, and glucose monitoring is continued for 1 week. bBood glucose control index of TIR , and the incidence of hypoglycemia and hyperglycemia, hospitalization days and cost was observed. This study ihas great clinical value.

The problems related to blood glucose in non-endocrine departments are becoming more and more serious.Glucose control level is closely related to the prognosis and cost of inpatients.
