Objective To investigate the clinical efficacy of insulin pump in the treatment of diabetes com-plicated with primary treated positive bacteria pulmonary tuberculosis. Methods 94 patients with type 2 diabetes mellitus complicated with pulmonary tuberculosis were randomly divided into two groups. All patients were given the conventional treatment, and the control group was treated with subcutaneous injection of insulin and the observation group was treated with insulin pump therapy. Their curative effect was compared. Results The cavity closure and the focus absorption rate were significantly higher in the observation group than in the control group 4 and 12 weeks after the treatment (P < 0. 05). The using dose of insulin was significantly lower in the observation group than in the control group. The observation group had shorter time of blood glucose back to normal than the control group had. Blood glucose level was maintained longer after stopping insulin injection and hypoglycemia happened less than those in the control group. Conclusion In the treatment of diabetic complicated with primary smear positive pulmonary tu-berculosis, insulin pump can reduce the dose of insulin to maintain stable blood glucose level and improve the cura-tive effect of pulmonary tuberculosis.%目的：探讨胰岛素泵治疗糖尿病合并初治菌阳肺结核的疗效。方法将94例2型糖尿病合并肺结核患者随机分组，除基础治疗外，对照组采用胰岛素皮下注射，观察组采用胰岛素泵，比较其疗效。结果两组治疗4周及12周后空洞闭合及病灶吸收率均明显增高(P <0．05)。观察组痰菌阴转率、空洞闭合及病灶吸收率均高于对照组，且观察组胰岛素剂量低，血糖达标时间短，低血糖发生率低(P <0．05)。结论在糖尿病合并初治菌阳肺结核的治疗中，胰岛素泵能降低胰岛素剂量，维持血糖稳定，提高疗效。
