title: [Clinical features, levels of protein carbonyl in serum of obstrucitive sleep apnea syndrome with type 2 diabetes mellitus].
abstract: OBJECTIVE
  To explore the prevalence, clinical feature and levels of protein carbonyl (PCO) in serum of type 2 diabetes mellitus combining obstrucitive sleep apnea syndrome (OSAHS).
  
  
  METHODS
  Two hundred and three patients with type 2 diabetes were taken multi lead sleep detection and their AHI, age, height, body mass index (BMI),waistline, duration of diabetes, fast blood glucose, HbA1c level and level of PCO in serum were recorded.
  
  
  RESULTS
  The prevalence of OSAHS was 79.2% in 203 patients, serious apnea 30.4%, moderate apnea 45.4%, mild apnea 24.2%. BMI, waistline, fast blood glucose, HbA1c level and level of PCO in serum were higher in patients complicated with OSAHS (P < 0.01). HbA1c was independently and positively correlated with patients with OSAHS risk (P < 0.05, OR 6.11). The independent correlation factors of AHI included HbA1c level,BMI, waistline, duration of diabetes and level of PCO in serum,with HbA1c as the predominant factor (P < 0.05).
  
  
  CONCLUSIONS
  The prevalence of OSAHS was higher in patients of type 2 diabetes mellitus combining (OSAHS). Moreover, in these patients poor glucose control and aggravated protein oxidative injury were observed.
