  • Prognostic Analysis of Chronic Obstructive Pulmonary Disease and Respiratory Failure Patients with Upper Gastrointestinal Bleeding

    ObjectiveTo investigate the relationship between chronic obstructive pulmonary disease (COPD) and respiratory failure in patients with upper gastrointestinal bleeding and recent prognosis. MethodsWe retrospectively analyzed the clinical data of 73 patients with COPD and respiratory failure treated from February 2009 to May 2011. The patients were assigned to the observing group (n=33) and control group (n=40). General characteristics, improvement rates, mortality rates, lengths of hospital stay, endotracheal tube rates and arrhythmia rates were compared between the two groups. ResultsAge, sex, and medical history of the patients were similar in both groups (P>0.05). Compared with the control group, the improvement rate was lower (P<0.001), the mortality rate (P<0.001), length of hospital stay (P<0.001), endotracheal tube rate (P<0.05) and arrhythmia rate (P<0.05) were all higher in the observing group after treatment. ConclusionUpper gastrointestinal bleeding is a high risk factor for short-term prognosis patients with COPD and respiratory failure.

  • Rat Model of Chronic Obstructive Pulmonary Disease Combined with Type 2 Diabetes Mellitus

    ObjectiveTo investigate the establishment of rat models with chronic obstructive pulmonary disease (COPD) combined with type 2 diabetes mellitus (DM). MethodsEighty 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. ResultsBronchial 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). ConclusionRat 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.
