Correlation study on Chinese medical syndrome types of chronic hepatitis B patients and HLA-DR13 gene, BCP mutation, and T-lymphocyte subsets / 中国中西医结合杂志

ABSTRACT

<p><b>OBJECTIVE</b>To explore the correlation between the HLA-DR13, basic core promoter (BCP), changes of T lymphocyte subset and clinical Chinese medical syndromes of chronic hepatitis B (CHB).</p><p><b>METHODS</b>Totally 102 CHB patients were syndrome typed as Gan depression Pi deficiency syndrome (GDPDS), Pi-Shen yang deficiency syndrome (PSYDS), Gan-gallbladder dampness heat syndrome (GGDHS), Gan-Shen yin deficiency syndrome (GSYDS), and static blood blocking collaterals syndrome (SBBCS). Besides, 30 healthy subjects were recruited as the normal control group. The blood HBV-DNA level and HLA-DR13 gene were detected with real time fluorescent PCR. The expression of CD4+ and CD8+ in T lymphocytes was detected using flow cytometry. The mutation of serum A1762T/G1764A was detected using PCR sequencing. Hepatitis Be antigen (HBeAg) was detected with ELISA, and correlation between various Chinese medical syndrome types and objective indicators were analyzed.</p><p><b>RESULTS</b>There was no statistical difference in HBV-DNA quantitative results among various syndrome types (P > 0.05). HBeAg positive rate was higher in GDPDS than in other syndrome types (P < 0.05). It was sequenced as GDPDS > GSYDS > SBBCS > GGDHS > PSYDS. Compared with the normal control group, percentages of CD3+ and CD3+ CD4+ were lower in PSYDS (P < 0.05). The ratio of CD3+ CD4+/CD3+ CD8 was lower in GGDHS and PSYDS than in the normal control group (P < 0.05). There was no statistical difference in the CD3+ CD8+ percentage among various syndrome types (P > 0.05). The quantitation of HLA-DR13 gene was lower in GDPDS and GSYDS than in the normal control group (P < 0.05). The positive rate of BCP mutation was higher in GSYDS than in other syndrome types (P < 0.05).</p><p><b>CONCLUSION</b>Co-detection results of HLA-DR13 and BCP could be used as reference indices of Chinese medical syndrome typing of CHB.</p>
