摘要
目的:探讨变应性鼻炎(AR)患者IL-4、IFN-γ基因启动子区甲基化在新疆维吾尔族、汉族不同人群AR中的差异。方法:选择维吾尔族、汉族AR患者各50例,用甲基化特异性PCR(MSP)检测IL-4、IFN-γ基因的甲基化。结果:维吾尔族、汉族AR患者IL-4基因启动子区完全甲基化率为44%(22/50)和48%(24/50),未甲基化率为26%(13/50)和22%(11/50),甲基化与未甲基化共存率为30%(15/50)和30%(15/50);维吾尔族、汉族AR患者IFN-γ基因启动子区完全甲基化率为12%(6/50)和16%(8/50),未甲基化率8%(4/50)和10%(5/50),甲基化与未甲基化共存率为80%(40/50)和74%(37/50)。维吾尔族与汉族AR患者IL-4基因甲基化分布状态相比差异无统计学意义(P>0.05)。维吾尔族与汉族AR患者IFN-γ基因甲基化分布状态相比差异无统计学意义(P>0.05)。结论:IL-4、IFN-γ基因甲基化程度在汉族与维吾尔族患者中均无差异。
Objective:To investigate the differences of IL-4, IFN-y gene promoter methylation of allergic rhi- nitis patients between Uygur and Han people of Xinjiang. Method:Methylation-specific PCR (MSP) detected IL-4, IFN-7 gene methylation of each of 50 patients with allergic rhinitis in Uygur and Han. Result:Complete IL-4 gene promoter methylation rate was 44 % (22/50) and 48%(24/50) in Uygur and Han AR patients, unmethylation was 26%(13/50) and 22% (11/50), coexistence rate of methylation and unmethylation was 30% (15/50) and 30% (15/50). Complete IFN-y gene promoter methylation rate was 12 % (6/50) and 16 % (8/50) in Uygur and Han AR patients, unmethylation 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 methylatin between Han and Uygur AR patients had no statistically significant(P〈0.05). Distribution of IFN-y gene methylation between Han and Uygur AR patients had no statistically significant(P〈0.05). Conclusion: There is no difference of IL-4, IFN-7 gene methylation in pa- tients between the Han and Uygur.
