摘要
目的探讨干扰素-γ诱导的单核因子(monokine induced by IFN-γ,Mig)、单核细胞趋化蛋白-1(monocyte chemoattractant protein-1,MCP-1)、转化生长因子-β1(transforming growth factorβ1,TGF-β1)在变应性鼻炎发病中的作用及变应性鼻炎患者Th1/Th2/Th3亚群的功能状态。方法抽取变应性鼻炎患者和健康对照者外周血,用ELISA法检测血清Mig、MCP-1及TGF-β1的含量。结果健康对照组血清Mig为(90.99±21.92)pg/ml,高于变应性鼻炎组的(-4.91±28.01)pg/ml及变应性鼻炎合并哮喘组的(-8.33±8.34)pg/ml(P=0.000)。变应性鼻炎患者血清MCP-1浓度为(81.16±1.40)pg/ml,明显高于健康对照组的(51.56±2.91)pg/ml(P=0.000);变应性鼻炎合并支气管哮喘患者血清MCP-1浓度为(103.31±11.32)pg/ml,较单纯变应性鼻炎患者高(P=0.003);MCP-1与速发相反应的相关典型症状,如鼻塞(r=0.380,P=0.001)、喷嚏(r=0.314,P=0.006)、流涕(r=0.417,P=0.000)、体征(r=0.455,P=0.000)呈正相关。变应性鼻炎及变应性鼻炎合并哮喘患者血清TGF-β1分别为(51.66±5.42)和(54.43±5.10)ng/ml,高于健康对照组的(44.17±7.33)ng/ml(P=0.000),TGF-β1与鼻塞(r=0.882,P=0.000)、流涕(r=0.288,P=0.013)、体征(r=0.559,P=0.000)呈正相关。健康对照组、变应性鼻炎组、变应性鼻炎合并哮喘组血清MCP-1及TGF-β1表达不存在因年龄、性别引起的统计学差异。结论变应性鼻炎和支气管哮喘存在Th2亚群强势,变应性鼻炎患者体内出现保护性(或调节性)Th3功能增强,不同年龄、性别不影响血清MCP-1及TGF-β1表达。
Objective To investigate whether Mig, MCP-1, and TGF-β1 play role in the mechanism of allergic rhinitis and functional status of Th1/Th2/Th3 subsets.Methods To detect the expression of Mig, MCP-1, and TGF-β1 in allergy rhinitis by ELISA method.Results The level of both MCP-1 and TGF-β1 is higher in both allergic rhinitis and bronchial asthma group than in normal control.The level of serum MCP-1 is statistically correlated positively with nasal obstruction, nasal discharge, rhinocnesmus, and sign.While the level of serum TGF-β1 is statistically positively correlated with nasal obstruction, nasal discharge and sign.There were not any significant differences in the level of serum MCP-1 and TGF-β1 between the two gender or among different ages.Conclusion Both Th2 and Th3 is enhanced.There is no gender and age difference in serum MCP-1 and TGF-β1 level.
