摘要： 目的 探讨肿瘤坏死因子α（TNF?α）基因启动子区域多态性与泛发性脓疱性银屑病的相关性。方法 检测对象为91例汉族泛发性脓疱性银屑病患者及102例汉族健康体检者，应用PCR及直接测序法分析TNF?α基因启动子区域?238、?308、?857位点多态性。结果 泛发性脓疱性银屑病患者与健康对照组TNF?α?238位点G/A等位基因频率差异有统计学意义（P = 0.003；OR = 4.819，95% CI：1.581 ~ 14.694），基因型GG与GA/AA在两组间的分布差异也有统计学意义（P = 0.006；OR = 4.455，95% CI：1.410 ~ 14.077）；TNF?α?308位点G/A等位基因频率以及基因型GG与GA/AA的分布在两组间差异无统计学意义（P值分别为0.794、0.786）；TNF?α?857位点C/T等位基因频率以及基因型CC与CT/TT的分布在两组间差异无统计学意义（P值分别为0.474、0.453）。结论 TNF?α?238G > A多态性可能与泛发性脓疱性银屑病发病相关。

Methods Totally, 91 patients of Han nationality with generalized pustular psoriasis （generalized pustular psoriasis group） and 102 health checkup examinees （healthy control group） were enrolled into this study. PCR and direct sequencing were performed to analyze the -238, -308 and -857 polymorphic sites of the TNF-α promoter. Results The frequency of the A allele at TNF-α-238 site was significantly higher in the generalized pustular psoriasis group than in the healthy control group （P = 0.003, OR = 4.819, 95% CI: 1.581 - 14.694）, so was the frequency of GA/AA genotype （P = 0.006, OR = 4.455, 95% CI: 1.410 - 14.077）. However, no significant differences were observed in the frequencies of G/A alleles （P = 0.794） and GG/GA/AA genotypes （P = 0.786） at TNF-α-308 site, or in the frequencies of C/T alleles （P = 0.474） and CC/CT/TT genotypes （P = 0.453）at TNF-α-857 site, between the generalized pustular psoriasis group and healthy control group. Conclusion TNF-α-238G > A polymorphisms may be associated with the occur-rence of generalized pustular psoriasis.
