[Relationship between gene polymorphisms of interleukin-10 and syndrome types of traditional Chinese medicine in post-hepatitis B cirrhosis].

OBJECTIVE

To investigate the relationship between single-nucleotide polymorphisms (SNPs) of interleukin-10 (IL-10) and syndrome types of traditional Chinese medicine (TCM) in posthepatitis B cirrhosis.

METHODS

The genotypes of IL-10-592 A/C, -819 C/T and -1082 G/A sites were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), and polymerase chain reaction-ligase detection reaction (PCR-LDR) combined with the sequencing analysis in 226 cases of posthepatitis B cirrhosis. The genotype and allele frequency distribution, and the relationship between the SNPs and TCM syndromes were analyzed.

RESULTS

The frequency of allele C at IL-10-819 point in spleen deficiency with overabundance of dampness syndrome was significantly higher than that in non-spleen deficiency with overabundance of dampness (P<0.01) syndrome, and genotype TT in liver stagnation syndrome was significantly higher than that in non-liver stagnation syndrome (P<0.05). There was no significant relationship between the polymorphisms of IL-10-592 A/C, -1082 G/A and the TCM syndromes in posthepatitis B cirrhosis (P>0.05).

CONCLUSION

In patients with posthepatitis B cirrhosis, allele C in IL-10-819 locus may be related to spleen deficiency with overabundance of dampness syndrome, and TT genotype in IL-10-819 locus may be related to liver stagnation syndrome.
