Study on the correlation between chronic asymptomatic HBV carriers of yin asthenia constitution and genotypes of HLA-DRB1 and HLA DQA1 alleles / 中国中西医结合杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study on the correlation between chronic asymptomatic HBV carriers (ASC) of yin asthenia constitution and genotypes of HLA-DRB1 and HLA DQA1 alleles.</p><p><b>METHODS</b>Totally 105 ASC were assigned to two groups according to their constitutions, i.e., the yin asthenia group (47 cases) and the non-yin asthenia group (58 cases). The genotypes of HLA-DRB1 and HLA DQA1 alleles were determined using PCR-SSP.</p><p><b>RESULTS</b>The gene frequency of HLA-DRB1 * 09 allele and HLA-DQA1 * 0301 allele (being 12.1% and 19.1%) were obviously lower in the yin asthenia group than in the non-yin asthenia group (being 27.8% and 39.7%, P < 0.05). The gene frequency of HLA-DRB1 * 11 allele and HLA-DQA1 * 0501 allele were obviously higher in the yin asthenia group (being 12.1% and 28.7%) than in the non-yin asthenia group (4.3% and 9.5%), showing statistical difference (P < 0.05, P < 0.01).</p><p><b>CONCLUSIONS</b>HLA-DRB1 * 09 allele and HLA-DQA1 * 0301 allele might be the molecular bases for non-yin asthenia patients with ASC. HLA-DRB1 * 11 allele and HLA-DQA1 * 0501 allele might be the molecular bases for yin asthenia patients with ASC.</p>
