title: [Association of chinese medicine constitution and human leukocyte antigen-DQA1 gene polymorphism with outcomes of hepatitis B virus infection].
abstract: OBJECTIVE
  To observe the Chinese medicine constitution types and human leukocyte antigen (HLA)-DQA1 gene polymorphism in patients with hepatitis B (HB) virus infection in Chinese Han population of Zhejiang Province, for exploring the roles of constitution factor in pathogenesis of HB.
  
  
  METHODS
  A total of 240 subjects, including 120 biopsy-proven chronic HB (CHB), 60 HB asymptomatic carrier (ASC) and 60 resolved from HBV infection spontaneously (RHBS) were studied. Their Chinese medicine constitution type was judged by Wangqi's classification, and their genotype of HLA-DQA1 was detected by polymerase chain reaction sequence specific primer for comparing the difference between groups in distribution frequency (DF) of constitution types and genes.
  
  
  RESULTS
  (1) As compared with the RHBS group, DF of yin-deficiency constitution and phlegm-dampness constitution in the CHB group was significant higher (20.0% vs. 6.7% and 12.5% vs. 1.7%), and that of placid constitution was significant lower (11.7% vs. 31.7%), showing statistical significance between groups (OR = 3.5, 95% CI: 1.16-10.60; OR = 8.4, 95% CI: 1.09-65.42; OR = 0.161, 95% CI: 0.076-0.34; all P < 0.05). (2) As compared with the ASC group, DF of damp-heat constitution was significant higher (24.2% vs. 6.7%, P < 0.05, OR = 4.462, 95% CI: 1.49-13.36), and that of placid constitution was significant lower (11.7% vs. 45.0%, P < 0.01, OR = 0.285, 95% CI: 0.13-0.62) in the CHB group. (3) As compared with RHBS group, DF of HLA-DQA1 * 0201 allele in CHB group was significant higher (38.3% vs. 5.8%, P < 0.01, OR = 10.04, 95% CI: 4.48-22.48); and that of HLA-DQA1 * 0102 allele was significant lower (9.6% vs. 36.7%, P < 0.01, OR = 0.183, 95% CI: 0.10-0.32). (4) As compared with ASC group, DF of HLA-DQA1 * 0201 allele in CHB group was significant higher (38.3% vs. 7.5%, P < 0.01, OR = 7.667, 95% CI: 3.7-15.87), and that of HLA-DQA1 * 0102 allele was significant lower (20.0% vs. 9.6%, P < 0.01, OR = 0.424, 95% CI: 0.23-0.79).
  
  
  CONCLUSIONS
  Both Chinese medicine constitution and HLA-DQA1 gene polymorphism show connection with the outcomes of HB virus infection in Chinese Han population, but the real association between them is required for further study.
