Objective To observe and compare the clinical efficacy,recurrence rate and safety of differ-ent courses of inhalation fluticasone propionate in treatment of children with cough variant asthma. Methods A total of 101 children with cough variant asthma in our hospital were randomly divided into three treatment groups,all with the same therapy drug -fluticasone propionate and with the treatment time of two months, six months and nine months respectively. Clinical efficacy and treatment compliance were followed up during the treatment. After discontinuation,observation for the relapse of cough was followed up for 6 months. In inhalation therapy before and after,bone mineral density( BMD) and blood cortisol,electrocardiogram were monitored re-spectively to observe its safety. Results Three groups of children with cough were all get effective control,with no significant difference(H=5. 2894,P=0. 0710). The two months treatment group(A group)was more easy to relapse than the six months treatment group( B group) and the nine months treatment group( C group) after drug withdrawal,statistically significant(χ2 =4. 858 1,P=0. 027 5;χ2 =4. 482 6,P=0. 034 2). But after drug with-drawal,there was no significant difference in the rate of relapse in B and C group(χ2 =0. 022 2,P=0. 881 4). There were few changes in laboratory values about morning serum cortosol concentrations. There was no signifi-cant decrease in BMD after treatment. No other adverse events were observed in this study. Conclusion Flutica-sone propionate inhalation treating children cough variant asthma has good effection. A long period of treatment scheme(6 months)has better curative effect and lower recurrence rate after drug withdrawal.

Objective To investigate the role of soluble triggering receptor expressed on myeloid cell-l (sTREM-1) in children with community acquired pneumonia.Methods One hundred and seventy-six children with community acquired pneu-monia, 98 cases were mild and 78 cases were servere, were recruited. Thirty healthy children were recruited as control group. The white blood cell count (WBC), neutrophil percentage (N%), C-reactive protein (CRP), procalcitonin (PCT), interleukin-6 (IL-6), interleukin-10 (IL-10), and sTREM-1 were measured.Results The levels of WBC, N%, CRP, IL-6, IL-10, IL-6/IL-10, PCT, and sTREM-1 were signiifcantly different among children with mild pneumonia, severe pneumonia, and healthy controls. All of the indicators were elevated in children with mild and severe pneumonia than those in healthy controls (P<0.05). IL-6/IL-10 sTREM-1 were further signiifcantly elevated in children with severe pneumonia than children with mild pneumonia (P<0.05). IL-6/IL-10 was positively correlated with sTREM-1 (r=0.42,P<0.05).Conclusions sTREM-1 may help for evaluating the severity and outcome of children with community acquired pneumonia.
