Analysis of skin prick test results in children with bronchial asthma and allergic rhinitis in Children's Hospital of Soochow University / 中国实用儿科杂志

OBJECTIVE: To use skin prick test to understand the main allergens in patients with bronchial asthma and allergic rhinitis,and to provide important evidence for its prevention,diagnosis and treatment. METHODS: A total of 2252 patients diagnosed with bronchial asthma or allergic rhinitis between August 2015 and July 2017 in the outpatient department of Children's Hospital Affiliated to Suzhou University were tested for allergens by skin prick test,and sex and disease types were analyzed by SPSS 21.0. RESULTS: The skin prick test was performed in 2252 patients,1390 cases were positive,and the positive rate was 61.7%;the ratio of male to female was 1.75∶1;the positive rate in boys was(925/1433,64.5%)higher than that of girls(465/819,56.8%)(P<0.05). The positive rate in children with bronchial asthma was 65.3%(607/929),the positive rate in allergic rhinitis was 58.8%(664/1129),and the positive rate in bronchial asthma combined with allergic rhinitis was 61.3%(119/194). The positive rate of bronchial asthma group was higher than that of allergic rhinitis group(P<0.05). Dust mites(60.3%)and house dust mites(43.4%)were most common,followed by grass pollen and cat hair. CONCLUSION: The most common allergens in children with bronchial asthma and allergic rhinitis in Suzhou Children's Hospital are mites;skin prick test provides a basis for the diagnosis of allergic diseases.

Studies on evaluation of sustained release tablets of extracts of Ginkgo biloba releasing rate in vitro by pharmacological indicatrix / 中国中药杂志

Using sustained release tablets of Ginkgo bibolia extract as model drug,discuss technical feasibility of using biotic index to evaluate sustained release tablets. Chosing two pharmacological indicatrix: antioxidant ability and inhibition of platelet aggregation, to investigate the influence factors on experimental result, optimize the method and experiment condition, and set up pharmacological indicatrix evaluation method. Using those methods to determinate biological effects of dissolved liquid. Drawing release curves and biological effects curves, discussing their correlation. A good correlation was observed, illustrating that pharmacological indicatrix could evaluate sustained release tablets.
