Objective To evaluate the effect of insulin pumps in diabetic patients. Methods Perioporative 37 diabetic patients in our hospital were randomly divided into two groups;19 patients were given continuous insulin pump subcutaneously(CS Ⅱ), 18 multiple subcutaneous injection(MS Ⅱ), comparing the level of blood sugar control, pre-operative time, control of blood sugar levels, wound healing, and so on, postoperative enteral nutrition. Results Two groups of blood glucose levels before treatment had no significant difference (P > 0.5), after treatment the de-creased level of blood sugar and blood sugar level of stability in the CS Ⅱ group better than the MS Ⅱ group, the differ-ence was signifieant(P <0.01). CS Ⅱ significantly shortened the pre-operative preparation time,before and after op-eration and postoperative enteral nutrition ,control of blood sugar stable ,the wound healed well and shortened hospital stay. Conclusion Insulin pump is an effective manner in the perioperative treatment of diabetes for smoothing opera-tion, reducing the burden on patients and complications.

Objective To compare the clinical effects and safety of treating newly diagnosed type 2 diabetes patients by combining Glargine insulin with Metformin or/and Acarbose. Methods 84 patients with newly diagnosed type 2 diabetes ,who have a history of weight loss, body mass index( BMI )23 ～ 28kg/m2 and poorly controlled blood glucose in Metformin at least a month ,were randomly divided into three groups. Glargine insulin plus Mefformin were used in group A. Glargine insulin plus Acarbose(without mefformin)were used in group B, Glargine insulin, Acarbos and metformin were used in Group C. All three groups were given a 12-week follow-up. Results FBG,2hBG and HbA1c levels were lower in the patients after treatment( P ＜0. 05 ). HbA1c of patients was partly up to the standard in group A and group B,but HbA1c of patients was all up to the standard in group C. The effects in group C were better than those in group A and group B. It had the shortest time to achieve the target and the smallest dose of insulin in group C. BMI in group A and B did not change but decreased in group C(P＞0.05).The incidence of low blood sugar in all three groups was low and no significant difference observed among three groups (P＞0.05). And in all three groups no severe hypoglycemia occurred. Conclusion The method of combining Glargine insulin with Mefformin or/and Acarbose could effectively control blood sugar had little impact on body weight of the newly diagnosed type 2 diabetes patients, and moreover, the incidence of low blood sugar in the newly diagnosed type 2 diabetes patients was lower. It would be the ideal method to treat newly diagnosed type 2 diabetes patients considering the general safety and effectiveness and convenience.
