To investigate the differences of IL-4, IFN-gamma gene promoter methylation of allergic rhinitis patients between Uygur and Han people of Xinjiang.
Methylation-specific PCR (MSP) detected IL-4, IFN-gamma gene methylation of each of 50 patients with allergic rhinitis in Uygur and Han.
Complete IL-4 gene promoter methylation rate was 44% (22/50) and 48% (24/50) in Uygur and Han AR patients, un-methylation was 26% (13/50) and 22% (11/50), coexistence rate of methylation and un-methylation was 30% (15/50) and 30% (15/50). Complete IFN-gamma gene promoter methylation rate was 12% (6/50) and 16% (8/50) in Uygur and Han AR patients, un-methylation was 8% (4/50) and 10% (5/50), coexistence rate of methylation and unmethylated was 80% (40/50) and 74% (37/50). Distribution of IL-4 gene methylation between Han and Uygur AR patients had no statistically significant (P > 0.05). Distribution of IFN-gamma gene methylation between Han and Uygur AR patients had no statistically significant (P > 0.05).
There is no difference of IL-4, IFN-gamma gene methylation in patients between the Han and Uygur.
探讨新疆维吾尔族和汉族变应性鼻炎患者白细胞介素-4（IL-4）、γ干扰素（IFN-γ）基因启动子甲基化的差异。
采用甲基化特异性PCR（MSP）法检测50例维吾尔族和汉族变应性鼻炎患者IL-4、IFN-γ基因的甲基化情况。
维吾尔族和汉族变应性鼻炎患者中IL-4基因启动子完全甲基化率分别为44%（22/50）和48%（24/50），未甲基化率分别为26%（13/50）和22%（11/50），甲基化与未甲基化共存率分别为30%（15/50）和30%（15/50）。维吾尔族和汉族变应性鼻炎患者中IFN-γ基因启动子完全甲基化率分别为12%（6/50）和16%（8/50），未甲基化率分别为8%（4/50）和10%（5/50），甲基化与未甲基化共存率分别为80%（40/50）和74%（37/50）。汉族和维吾尔族变应性鼻炎患者IL-4基因甲基化分布差异无统计学意义（P>0.05）。汉族和维吾尔族变应性鼻炎患者IFN-γ基因甲基化分布差异无统计学意义（P>0.05）。
汉族和维吾尔族变应性鼻炎患者IL-4、IFN-γ基因甲基化无差异。
