摘 要:目的探讨缺血性脑卒中(Is)与人类白细胞抗原(HLA)基因表达的关联。方法采用聚合酶链反应一直接测序分型方法(PCR-SBT)对广东医学院附属南山医院2008-2012年94例住院Is患者和503名深圳居住的健康对照人群,进行HLA-A、B、C、DRBl、DQBl抗原、等位基因及单倍型分析。结果(1)IS组表达出HLA-A抗原11个,等位基因17个;HLA-B抗原20个,等位基因34个;HLA-C抗原11个,等位基因16个;HLA-DRB1抗原13个,等位基因26个;HLA-DQB1抗原5个,等位基因13个。(2)IS组HLA-A$31:01(P=0.0169,RR:2.827),B女37:01(P=0.0066,RR=4.613),DRB1*11:06(P=0.0002,RR=37.981)等位基因频率升高。(3)IS组HIJA-DRBl*11:06-DQB1*03:01单倍型频率升高(P=0.001,RR=38.52)。结论研究显示HLA-B$37:01,DRB1*11:06,单倍型HLA.DRB1*11:06.DQB1*03:01与Is发生呈易感关联,在Is的发生中HLA基因具有遗传作用。Objective To explore the correlation between ischemic stroke (IS) and the polymorphism of human leucocyte antigen (HLA) gene. Methods Antigen, allele, haplotype of HLA-A, B, C, DRB1, DQB1 in 94 IS patients and 503 healthy controls were detected by PCR-SBT. Results ( 1 ) There were 11 antigens, 17 alleles in HLA-A locus, 20 antigens, 34 alleles in HLA-B locus, 11 antigens, 16 alleles in HLA-C locus, 13 antigens, 26 alleles in HLA-DRB1 locus, 5 antigens, 13 alleles in HLA DQB1 locus in IS group. (2) The allellic frequency of HLA-A * 31:01 (P = 0. 016 9, RR = 2. 827), HLA-B * 37:O1 ( P = O. 006 6, RR = 4. 613) and HLA-DRB1 * 11 : 06 (P = 0. 000 2, RR = 37. 981 ) in the IS patients was higher than that in healthy controls. (3) The haplotypic frequency of HLA-DRB1 * 11:06-DQB1 * 03: 01 (P = 0. 001, RR = 38.52) in the IS patients was higher than that in healthy controls. Conclusion The susceptibility association of HLA-B * 37: 01, HLA-DRB1 * 11:06 and HLA-DRB1 * 11:06-DQB1 * 03:O1 with IS and HLA gene play a genetic role in the occurrence of.
