目的:探讨 HLA-B 特异性抗原 Bw4与新疆汉族鼻咽癌发病的关系。方法应用聚合酶链反应-序列特异性引物(PCR-SSP)技术,对131例汉族鼻咽癌患者(鼻咽癌组)和168例汉族健康体检者(对照组)进行HLA-B 位点等位基因分型,确定 Bw4、Bw6抗原的特异性分布,分析 HLA-B 携带 Bw4对鼻咽癌患者 CD4+、CD8+T 淋巴细胞亚群的影响。结果(1)鼻咽癌组 Bw4抗原携带者66例(50.4%),健康对照组 Bw4抗原携带者120例(71.4%),鼻咽癌组 Bw4抗原表达频率明显低于健康对照组,两组比较差异有统计学意义(χ2=13.869,P =0.000)。(2)鼻咽癌组 CD4+ T 淋巴细胞水平低于健康对照组,CD8+ T 淋巴细胞水平高于健康对照组,两组比较差异均有统计学意义(t =2.765,P =0.009;t =-1.768,P =0.043)。(3)鼻咽癌患者中 Bw4阳性组 CD4+ T 淋巴细胞水平高于 Bw4阴性组,两组比较差异有统计学意义(t =3.002,P =0.005),两组 CD8+ T 淋巴细胞水平比较差异无统计学意义(P >0.05)。结论Bw4抗原的缺失可能与新疆汉族鼻咽癌的发生有关,HLA-B 特异性抗原Bw4对汉族鼻咽癌患者有一定的保护作用。

Objcetive To investigate the relationship between human leukocyte antigen-B(HLA-B)antigen carrying Bw4 and Han people with nasopharyngeal carcinoma (NPC)in Xinjiang.Methods Polymerase chain reaction-sequence specific primers (PCR-SSP)technique was employed to detect the allele frequency of HLA-B in 131 Han NPC patients and 168 normal controls.HLA-Bw genotypes were determined and their association with CD4 + T cell,CD8 + T cell were analyzed.Results (1)There were 66 (50.4%) cases with Bw4 in NPC,and 120(71.4%)cases with Bw4 in normal controls.The population frequency of Bw4 in NPC was lower than normal controls (χ2 =13.869,P =0.000).(2)The percentage of CD4+ T cell in Han NPC was lower than normal controls (t =2.765,P =0.009)and the percentage of CD8+ T cell in Han NPC was higher than normal controls (t =-1.768,P =0.043).(3)In NPC,the group with Bw4 had higher percentage of CD4+ T cell compared with the group without Bw4 (t =3.002,P =0.005)and there was no significant differences in the percentage of CD8+ T cell between the two groups (P >0.05).Con-clusion Bw4 deficiency was associated with Han NPC in Xinjiang.HLA-B antigen carrying Bw4 has pro-tective effect in Han NPC.
