Objective To investigate the establishment of rat models with chronic obstructive pulmonary disease (COPD) combined with type 2 diabetes mellitus (DM). Methods Eighty Sprague-Dawley (SD) male rats were randomly divided into four groups:COPD group (n=20), DM group (n=20), COPD combined with DM group (n=20) and normal group (n=20). COPD rats were established by cigarette smoke. Type 2 diabetes rats were modeled by streptozotocin injection. COPD combined with DM rats were modeled by cigarette smoking and streptozotocin injection at the same time. Pathological examination and blood glucose were tested after three months. Results Bronchial epithelium was seriously shedding in COPD+DM group, with alveolar structure damaged and some alveolar fused into bullae. The blood glucose level in COPD+DM group was (27.1±1.1) mmol/L, which was statistically different from other groups (P<0.05). Conclusion Rat model of COPD combined with type 2 DM could be established by cigarette smoking and streptozotocin injection, which can provide an animal model for further medical research.
