title: [Study on the relationship between WBC count levels and type 2 diabetes mellitus in Hui and Han nationality of Ningxia].
abstract: OBJECTIVE
  To analyze the relationship between WBC count levels and type 2 diabetes mellitus in Hui and Han nationality of Ningxia.
  
  
  METHODS
  Using the method of case-control study, people of regional organizations and institutions aged 20 - 60 who received medical health checkup and endocrine patients in General Hospital of Ningxia Medical College and WuZhong city People's Hospital from October 2011 to October 2012 were enrolled in the study. According to the inclusion and exclusion criteria of T2DM patients and control groups, with gender, ethnic and age are not more than 3 years old cases and controls of matching, the T2DM group (case group) of 351 cases and non-T2DM group (control group) of 655 cases were determined. These subjects underwent questionnaire investigation, understand first, like the situation, the way of life, disease and medication history, family history. Physical examination: including height, weight, waist circumference (WC), systolic blood pressure (SBP) and diastolic blood pressure (DBP), and according to the height and weight to calculate body mass index (BMI), and laboratory tests, triglyceride (TG), total cholesterol (TC), high-density lipoprotein (HDL-C), low density lipoprotein (LDL-C), blood uric acid (UA ), nmda aminotransferase ( AST) , alanine aminotransferase (ALT), blood biochemical indexes. Results Diabetes group of average age (50.28 + 8.32), 194 patients with male, (55.27%), 157 patients with female (44.73%) and control group in average age (50. 17 + 7. 14) , including 337 men (51.45% ) and 318 women (48.55%). Average age, gender, the proportion between the two groups had no statistical significance of difference. The white blood cell value of T2DM group (6.66 x 10(9) ± 1.61 x 10(9)/L) was higher than that of non-T2DM group (6.11 x 10(9) ± 1.49 x 10(9)/L), there was a significant difference (t = -5.430, P < 0.01); Comparing the mean value of white blood cell of Hui (6.459 x 10(9) ± 1.45 x 10(9)/L) and Han nationality (6.169 x 10(9) ± 1.63 x 10(9)/L), there was a significant difference (P < 0.05). T2DM group, the abnormal level of white blood cell was 2.6%, that of non-T2DM group was 0.8%, The T2DM group was significantly higher than that of non-T2DM group (χ2 = 4.168, P = 0.041). Comparing the abnormal level of white blood cell of Hui and Han nationality, there was no significant difference. After adjustment for age, gender, nation, TG, TC, HDL, LDL, ALT, AST and blood glucose, the odds ratios for T2MD were 4.072 in the people with the WBC abnormal people and the WBC normal people. After adjustment for age, gender sick or not, TG, TC, HDL, LDL, ALT, AST and blood glucose, the odds ratios for WBC increased were 1. 582 in the people with the Hui and Han nationality.
  
  
  CONCLUSIONS
  The WBC count levels are closely associated with type 2 diabetes, and with the increase of the level, the association enhanced gradually, the WBC may be involved in the occurrence and development of type 2 diabetes. there is a certain relationship between ethnic genetic factors and the WBC count level.
