[Objective] To investigate the changes of CD4~+ CD25~+ regulatory T cells (Tr) in peripheral blood and their relation with their body mass index (BMI) of children with acute attack asthma. [Methods] Peripheral blood was obtained from 70 children with acute attack asthma, 30 remission children, and 50 normal control children. Then 70 children with acute attack asthma, were divided by normal weight group (40 cases) and overweight group (30 cases). The levels of CD4~+CD25~+Tr of the patients were tested by flow cytometry (FCM), and their BMI were calculated. [ Results] The levels of CD4~+ CD25~+ Tr [(6.17± 1.72)%] in acute attack group were lower than that in remission group [(7.56±1.48)%] or that in the control group [(7.13± 1.48)%] (P<0.05), but no difference between that in the remission and that in the control (P>0.05). The CD4~+CD25~+Tr of asthmatic children with normal weight [(6.34±1.71)%] was higher than that of asthmatic children with overweight [(4.74±1.20)%] (P<0.05). There was a remarkably negative correlation between the level of CD4~+ CD25~+ Tr of asthmatic children [(6.17±1.72)%] and the BMI (16.00±2.14) (r_p=-0.814, P<0.05). [Conclusion] The levels of CD4~+ CD25~+Tr are remarkable decrease in attack asthmatic children, and more decrease in overweight patients. There is remarkably negative correlation between the levels of CD4~+CD25~+ Tr in peripheral blood of attack asthmatic children and their BMI.

AIM and METHODS: To study the immunological effect of measles vaccine therapy on asthmatic children, we examined the changes of interleukin-12 , interleukin-13 and total serum IgE levels in plasma and cultured peripheral blood mononuclear cells(PBMC) supernatant by means of ELISA in 13 mild-moderate asthmatic children treated with measles vaccine. Results were compared with 12 anti-symptomatic treatment mild-moderate asthmatic children and 17 normal children control group. RESULTS:After measles vaccine treatment, IL-13 and total serum IgE levels decreased remarkably, statistically lower than that of group receiving only anti-symptomatic treatment. There was no statistical difference in IL-12 level between the two group. Correlation analysis: 1)IL-12 level of plasma was negatively correlated to the level of serum total IgE, there was no correlation of supernatant IL-12 in PBMC to the total serum IgE; 2)IL-13 levels in plasma and PBMC were positively correlated to the level of total serum IgE; 3) IL-12 level was negatively correlated to IL-13. CONCLUSION: Measles vaccine could down-regulate IL-13 level, therefore decrease total IgE synthesis, but not affect IL-12 level in asthmatic children.

[Objective] This study was designed to determine Th1, Th2 cell numbers and investigate T-bet mRNA, GATA-3 mRNA expression of spleen MNC in a mufine asthmatic model which intended to understand effect of airway T-bet plasmid gene transfer on Th differentiation. [ Methods] A mouse asthmatic model was established by sensitization with ovalbumin (OVA). Thirty-two C57BL/6 mice were divided into four groups (8 mice in each group): the normal control group (group A ), the asthmatic model group (group B), the pcDNA3 plasmid group (group C), the pcDNA3-T-bet group (group D). All animals were sensitized and challenged with OVA, except group A normal saline was applied. The group C was intranasally administered 50 μg pcDNA3 plasmid at 24 h before intranasal challenges, and the 50 μg pcDNA3-T-bet plasmid for the mice of group D. We investigated Th1 and Th2 cell numbers by FACS and T-bet, GATA-3mRNA expression of spleen mononuclear cells (MNC) by semi-quantitative PCR in the four groups. [Result] Th1 percent in spleen MNC of pcDNA3-T-bet treated mice was significantly increased ([2.29±1.551% vs. [1.93±1.141%, P<0.05), while Th2 percent was significantly decreased ([0.93±0.64]% vs. [1.63±0.59]%), compared with that of the asthmatic control group mice by FACS. Spleen MNC was detected a high level of T-bet mRNA expression (0.53±0.027 vs. 0.28±0.035, P<0.05) and a low level of GATA-3 mRNA expression (0.24±0.022 vs. 0.58±0.038, P<0.05) after pcDNA3-T-bet treatment by RT-PCR. There was no significant change between the pcDNA3 plasmid group and the asthmatic model group. [Conclusion] The intranasal transfer of pcDNA3-T-bet plasmid was effective in modulating the imbalance of Th1/Th2 in mice asthma model, which provides a novel therapeutic strategy for transferring transcriptional factor in allergic asthma.
