3 years old than those in ≤3 years old group.The incidence rate of the adverse reaction after SPT was 1.6%(6/384),there were 4 temporary fieber,1 asthma and 1 anaphylactic shock.Conclusions The common allergens are inhalant allergens of dermatophagoides pteronyssinus and dermatophagoides farina in Chongming island.The SPT is more suitable for over 3 years old children with typical anaphylaxis of respiratory symptom and maybe have the potential danger.

Juvenile idiopathic arthritis(JIA)is the most common rheumatology disease in childhood period with poor prognosis.The biological agents are newly developed drugs with features of clear therapeutic targets and fast effects.But its use in JIA is still limited,so this article focuses on the clinical use experience,timming and sideffects of the biological agents on JIA.

0.05).Conclusion The increasing of IL-15 in peripheral blood after MP infection may play a role in bronchitic asthma pathogenesis.

Objective To analyse the distribution characteristics of major allergens initiating allergic diseases in children from rural Shanghai. Methods Eight hundred children with allergic diseases from rural Shanghai (rural ease group), 450 children with allergic diseases from urban Shanghai (urban ease group) and 100 healthy children from rural Shanghai (rural normal control group) underwent skin prick tests (SPT), and children of rural case group were subdivided into infant group, preschool age group and school age group according to age. The positive rates of allergens and SPT were compared among groups. Results The positive rate of SPT of rural case group was significantly higher than that of rural normal control group (73.38% vs 26.00%, P<0.05), and was significantly lower than that of urban ease group (73.38% vs 80.22%, P<0.05). Dermatophagoidesfarinae and Dermatophagoides pteronyssinus were the major allergens in rural ease group, with the positive rates of 57.88% and 59.13%, respectively. Except weed and rubber, there were significant differences in positive rates of the other allergens between rural ease group and the other two groups(P<0.05). There were significant differences in positive rates of SPT among different age groups of rural children with allergic diseases (P<0.05). Conclusion Dermatophagoides farinae and Dermatophagoides pteronyssinus are the major allergens in children with allergic diseases from rural Shanghai, whose positive rates of SPT are lower than those of children with allergic diseases from urban Shanghai. The positive rate of SPT is related to age to some extent.

Objective To investigate the number of eosinophils in peripheral blood and total serum immunoglobulin E levels from children during infection of mycoplasma pneumoniae,which may elucidate what mycoplasma pneumoniae plays a role in persistent cough and asthma onset.Methods The number of eosinophils in peripheral blood was counted under microscope and total serum immunoglobulin E levels were determined by ELISA in 20 children with mycoplasmal infection ,30 patients with asthma and 25 control subjects.Results The number of eosinophils and total serum immunoglobulin E levels during mycoplasmal infection were significantly higher than in control group,and lower than in asthma.Conclusion The high eosinophil counts and total serum immunoglobulin E induced by mycoplasma pnemoniae play a key role in persistent cough and asthma attack.

Objective To investigate the protective role of FDP to STZ induced islest apoptosis and the potential mechanisms.Methods The pancreases of the rats were treated to collect islets cells.The cells were incubated with STZ with/or FDP.Cell morphology,insulin secretion,HO-1 activity,CO content,SOD activity,GSH-px activity,iNOS activity were examined.No conetent and apoptotic percentage was detected.Results HO-1 activity and CO content of the normal control group were low.STZ induced a significant decrease of cell activity and insulin release,flow cytometry analysis showed that apoptotic percentage of islet cells remarkably increased following the addition of STZ,FDP obviously improved the islets cellular activity damaged by STZ,basic amount of insulin secretion and stimulated by high glucose were improved(P
