摘 要:目的 探讨白细胞介素10(IL-10)启动子区-1082/-819/-592位点的多态性及其在血浆中的浓度与声带白斑发生的关系.方法 选择2012年10月至2013年2月61例声带白斑患者和119名正常人作对照研究,采用核苷酸直接测序法检测样本的IL-10基因位点(-1082G/A,-819C/T和-592C/A)的基因分型,用酶联免疫吸附法(ELISA)检测IL-10的血浆浓度.结果 吸烟和饮酒增加了罹患声带白斑的风险(OR为4.73和5.70,95% CI为2.4 ~9.1;2.9~11.2,P<0.01).声带白斑患者在IL-10的-592和-819位点比对照组有更高的AC突变频率(OR=1.93,95% CI为0.97~ 3.81,P=0.05),在-1082位点有更高的AG突变频率(OR =2.14,95% CI为0.87 ~5.27,P=0.092);声带白斑患者的血浆IL-10质量浓度为(21.6 ±0.5)pg/ml((x)±s),对照组为(19.0±1.1) pg/ml,两者比较差异有统计学意义(t=2.08,P=0.043).基因型中含有G基因的单倍体患者的血浆IL-10质量浓度(24.3±5.7)pg/ml,比正常基因型单倍体患者IL-10的浓度高(19.9 ±4.7) pg/ml,两者比较差异有统计学意义(t=-2.64,P=0.008).结论 IL-10启动子区-1082/-819/-592多态性及血浆中高浓度的IL-10与声带白斑的发生有关,同时,突变基因型与IL-10血浆浓度有关.Objective To investigated the association between interleukin-10( IL-10)-1082/-819/- 592 promoter polymorphism, plasma IL-10 levels and risk of vocal leukoplakia. Methods A case-control study of 61 patients with vocal cords leukoplakia and 119 healthy subjects were performed. Genotypes for the IL-10 gene ( IL-10 -1082 G/A, -819 C/T and -592 C/A) were determined using pyrosequencing and plasma IL-10 levels were analyzed by ELISA. Results Smoking and alcohol consumption increased the risk of vocal leukoplakia ( OR = 4.73, 95% CI:2. d - 9. 1 ; OR = 5.70, 95% CI:2. 9 - 11.2, P 〈 0. 01 ). Patients with vocal cord leukoplakia had significantly higher frequencies of AC at -592 and -819 ( OR = 1.93,95% CI: 0.97-3.81,P=0.05) and AG at -1082 ( OR = 2.14 , 95%CI:0.87-5.27, P=0.092) than control. Vocal leukoplakiapatients had higher concentration of plasma IL-10 (21.6 + 0. 5 ) pg/ml (x ± s) than controls ( 19. 0± 1.1 ) pg/ml( t = 2.08, P = 0. 043 ) and the haplotype containing the G allele was associated with higher plasma IL-10 concentrations ( 24. 3 ±5.7 ) pg/ml compared with the ATA haplotype ( 19.9± 4. 7 ) pg/ml(t = -2. 64, P = 0. 008). Conclusions IL-10-1082/-819/-592 promoter polymorphism and high concentration of plasma IL-10 are associated with vocal cord leukoplakia, and the concentration of plasma IL-10 is associated with the genotypes of IL-10 promoter polymorphism.
