ABSTRACT
<p><b>OBJECTIVE</b>Impulse oscillometry (IOS) is a novel technique for the evaluation of pulmonary function. Soluble intercellular adhesion molecule-1 (sICAM-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) are definitive indicators for the severity of asthma. This study aimed to explore the relationship of IOS pulmonary function with sICAM-1 and sVCAM-1, and their values in childhood asthma.</p><p><b>METHODS</b>IOS via Master Screen System for pulmonary function was performed in 40 children with acute asthma and 25 healthy children. Twenty-three of 40 children with acute asthma were re-tested for IOS pulmonary function at remission. sICAM-1 and sVCAM-1 levels were measured in 23 children with acute asthma, 20 asthmatic children at remission and 16 healthy children.</p><p><b>RESULTS</b>The parameters of IOS pulmonary function, R5, R20, R5-R20, X5, Fres and Zrs in children with acute asthma were significantly higher than in asthmatic children at remission and in normal controls (q= 2.91-15.61, P < 0.01 or 0.05). There were significant differences in R5, R5-R20, Fres and Zrs between the asthmatic children at remission and normal controls (q= 3.08- 9.19, P < 0.01 or 0.05). sICAM-1 and sVCAM-1 levels in children with acute asthma were significantly higher than in asthmatic children at remission and in normal controls (q= 6.23-26.15, P < 0.01). The asthmatic children at remission had higher levels of sICAM-1 and sVCAM-1 than the normal controls (q=16.86, 12.46, P < 0.01). R5-R20 positively correlated with sICAM-1 and sVCAM-1 in children with acute asthma (r=0.45, 0.57, P <0.05).</p><p><b>CONCLUSIONS</b>IOS for pulmonary function and sICAM-1 and sVCAM-1 may be used to evaluate the severity and therapeutic effects of childhood asthma. A correlation exists between IOS pulmonary function and sICAM-1 and sVCAM-1.</p>

Objective To study the effects of different glucocorticasteroid(GCS) inhalation regimens for remissive children with asthma. Methods Three hundred and twenty - three patients with moderate asthma were enrolled on a 12 - week randomized parallel group remissive treatment after a 4 - week baseline treatment. During the baseline treatment terbutaline sulfate 250 ?g tid a day and bud esonide 200 ?g twice a day were given, and oral bronchodilators were used if necessary. The remissive treatment were composed of budesomde inhabit ion 100 ?g once a day (group A), 100 ?g twice a day(group B) and 200 ?g once a day(group 0). Patients subsequently returned to the clinic for 3 additional clinic visits (4,8 and 12 weeks) or telephone visits . On every clinic visit, the daytime and nocturnal time seventy score were recorded and spirometry was conducted in patients who were capable of performing the maneuver. Results Ultimately, 323 children were enrolled on the baseline treatment and 281 (87%) children achieved clinical remission. The rate of compliance decreased gradually during the remissive treatment, but in group B(P
ABSTRACT
0.05).Conclusions The serum concentrations of cortisol,GH,IGF-Ⅰ and IGFBP3 in children suffered from asthma have no obvious change before and after 24 months long-term inhaled corticosteroids.The height changes before and after therapy have no significant difference between observation group and control group with same age and gender.
