目的:探讨布地奈德对支气管哮喘患儿外周血干扰素-γ(interferon-γ,IFN-γ)、白细胞介素-4(interleukin-4, IL-4)及叉状头状螺旋转录因子3(transcription factor FoxP3,FoxP3)表达的影响。方法筛选2010年6月至2013年10月在台州市中心医院就诊的哮喘患儿,将其分成轻、中、重度组,门诊正常体检儿童为正常对照组;采用酶联免疫分析法检测治疗前后IFN-γ、IL-4水平,采用流式细胞术检测表达FoxP3的CD4调节性T细胞及亚型比例。结果共纳入哮喘患儿68例。其中轻度哮喘组25例,平均年龄(6.3±4.1)岁;中度哮喘组28例,平均年龄(5.3±3.8)岁;重度哮喘组15例,平均年龄(5.8±4.5)岁。正常对照组25例,平均年龄(5.2±2.8)岁。治疗前3个哮喘组外周血CD4+CD25+调节性T细胞比例[轻度(10.8±1.5)%,中度(11.4±1.4)%,重度(9.9±1.0)%]和CD4+CD25+FoxP3+表达水平[轻度(4.7±0.4),中度(3.9±0.8),重度(3.5±0.7)]均低于对照组[CD4+CD25+调节性T细胞比例(13.7±2.0)%,CD4+CD25+FoxP3+(5.4±0.6)],差异有统计学意义(P<0.05),且随病情加重表达下降;IL-4表达[轻度(22.7±2.7)ng/L,中度(29.0±5.6)ng/L,重度(31.5±3.3)ng/L]显著高于对照组[(17.8±1.6)ng/L],差异有统计学意义(P<0.05),并随着疾病的加重表达增加。治疗前各哮喘组IFN-γ水平[轻度(21.9±2.8)ng/L,中度(20.5±3.4)ng/L,重度(16.1±3.2)ng/L]显著低于对照组[(25.8±3.4)ng/L],差异有统计学意义(P<0.05)。治疗前各哮喘组外周血CD4+CD25+调节性T细胞比例和CD4+CD25+FoxP3+表达水平显著低于治疗后[CD4+CD25+调节性T细胞比例:轻度(13.9±2.2)%,中度(13.4±1.7)%,重度(13.5±2.0)%;CD4+CD25+FoxP3+:轻度(5.6±0.8),中度(4.9±0.8),重度(5.2±0.9)],而IL-4表达高于治疗后[轻度(18.1±2.9)ng/L,中度(19.3±2.8)ng/L,重度(19.6±1.9)ng/L],差异均有统计学意义(P<0.05)。治疗前轻度哮喘组IFN-γ表达显著低于治疗后[(26.5±3.4)ng/L],差异有统计学意义(P<0.05);中、高度与治疗后相比[中度(23.5±3.7)ng/L,重度(19.9±3.1)ng/L],差异无统计学意义(P>0.05);所有检测项目经治疗后与对照组比较差异无统计学意义(P>0.05)。结论哮喘患儿体内存在辅助T细胞(T helper cell,Th)1/Th2失衡,可能是哮喘发病的重要原因,布地奈德能有效改善Th1/Th2失衡,并通过调节FoxP3的表达发挥治疗作用。

Objective Toinvestigatetheroleofinterferon-γ,interleukin-4andtranscriptionfactorFoxP3inthe pathogenesis of bronchial asthma in children and assess the effect of Budesonide on the expression of IFN-γ, IL-4andFoxP3.Methods Asthmachildrenweredividedintomild,moderateandseveregroupbasedon their severity and healthy control children were also recruited in this study from Jun. 2010 to Oct. 2013 in Taizhou Central Hospital. IL-4 and IFN-γwere detected by enzyme-linked immunosorbent assay and the percentageofFoxp3wasdetectedbyassayedbyflowcytometricanalysissystem.Results Sixty-eight children were enrolled in this study,25 [mean(6. 3 ±4. 1 )years old]in mild,28 [mean(5. 3 ±3. 8)years old]in moderate,15 [mean(5. 8 ±4. 5)years old]in severe group and 25 [mean(5. 2 ±2. 8)years old] in healthy control group. The expression of CD4 +CD25 +Treg(10. 8 ±1. 5% in mild group,1 1. 4 ±1. 4%in moderate group and 9. 9 ±1. 0% in severe group respectively)and CD4 +CD2 5 +FoxP3 +(4. 7 ±0. 4 in mild group,3. 9 ±0. 8 in moderate group and 3. 5 ±0. 7 in severe group respectively)in peripheral blood in three asthmatic groups were lower than in control group(CD4 +CD25 +Treg:13. 7 ±2. 0 %,CD4 +CD25 +FoxP3 +:5. 4 ±0. 6,P <0. 05 ),and decreased during aggravation. The expression of IL-4 in three asthmatic groups was higher than in control group (22. 7 ±2. 7 ng/L in mild group,29. 0 ±5. 6 ng/L in moderate group,31. 5 ±3. 3 ng/L in severe group and 17. 8 ±1. 6 ng/L in control group respectively)(P<0. 05 ),and increased during aggravation. The IFN-γlevels in children with bronchial asthma before treatment was significantly lower than that of the control group(21. 9 ±2. 8 ng/L in mild group,20. 5 ±3. 4 ng/L in moderate group, 16. 1 ±3. 2ng/L in severe group and 25. 8 ±3. 4 ng/L in control group respectively)(P<0. 05 ). Before treatment,peripheral blood CD4 +CD25 +Treg and CD4 +CD25 +FoxP3 +expression in bronchial asthma children were significantly lower than after treatment (CD4 +CD25 +Treg:13. 9 ±2. 2% in mild group, 13. 4 ±1. 7% in moderate group and 13. 5 ±2. 0% in severe group respectively;CD4 +CD25 +FoxP3 +:5. 6 ±0. 8 in mild group,4. 9 ±0. 8 in moderate group and 5. 2 ±0. 9 in severe group respectively)(P<0. 05). The expression of IL-4 was higher than after treatment(18. 1 ± 2. 9 ng/L in mild group, 19. 3 ±2. 8 ng/L in moderate group and 19. 6 ±1. 9 ng/L in severe group respectively)(P<0. 05 ). IFN-γexpression before treatment were significantly lower than after treatment in mild group(26. 5 ±3. 4 ng/L,)(P<0. 05 ),but the differences were not significant statistically between before and after treatment in moderate group(23. 5 ±3. 7)ng/L)and severe group(19. 9 ±3. 1 ng/L)(P>0. 05 ). The differences were not significant statistically among three asthmatic groups and control group in alldetectionresults(P>0.05).Conclusions TheimbalanceofTh1/Th2mayplayanimportantroleinthe pathogenesis of asthma in children. Budesonide can regulate Th1/Th2 balance,based on induction of the expression of Foxp3 CD4 +Treg cells.
