ABSTRACT
Objective To understand the distribution of allergens in children with common allergic diseases in Guangzhou, and to provide evidence for the prevention and treatment of environmental allergens in children with different allergic diseases. Methods This study enrolled a total of 6 869 children with allergic diseases, including wheezing diseases and asthma (1 013 cases), allergic rhinitis (660 cases), allergic conjunctivitis (422 cases), eczema (2 762 cases), atopic dermatitis (831 cases) and urticaria (1 181 cases). Western blotting was used to detect the serum allergen type E specific antibodies (sIgE) of the patients. The results were statistically analyzed. Results The total positive rate of sIgE in 6 869 children was 74.01%. The positive rate of male children (75.02%) was higher than that of female children (72.25%). The positive rate of inhalation allergens (53.47%) was higher than that of food allergens (57.39%). House dust mites and milk were the most common inhalation allergens and food allergens, respectively. Eczema was the most common allergic disease in infants and toddlers. Allergic rhinitis and urticaria were common in school-age children. Conclusion The main allergens causing allergic diseases in children in Guangzhou were dust mites and milk. Different allergic diseases had its specific allergens. It is necessary to take targeted prevention measures accordingly.
ABSTRACT
Objective To analyze the comparability of potassium results detected by blood-gas analyzer and dry chemical analy-zer .Methods Dry chemical detection system was used as comparison method (X) ,and blood gas analyzer systems was used as the experimental method (Y ) .Arterial blood samples collected from ICU newborns were detected respectively by the two methods .If SE of medical decision level was less than or equal to 1/2 TEa decided by CLIA′88 ,the results was acceptable .Results There was a linear correlation in potassium concentrations of the two detection systems(r=0 .976 ,P<0 .01) .But among three medical decision levels ,the SE of the two detection systems only acceptable at 3 .0 mmol/L .Conclusion The potassium concentration of blood gas analyzer is lower than that of dry chemistry analyzer .The potassium concentration of dry chemistry analyzer should be taken as a reference to diagnose and clinical treatment .
