RESUMEN
Objective@#To study the relationship between the single nucleotide polymorphism of HLA⁃A rs3132682 and the risk of liver cancer.@*Methods@#The author selected 291 cases of liver cancer patients in Yanbian area as the experimental group and 272 healthy people as the control group. The genotypes and allele frequencies of the two loci were detected by MassARRAY SNPS mass spectrometry. Odds ratio (OR) and 95% confidence interval (CI) were calculated by unconditional logistic regression to evaluate the risk of liver cancer in patients with different genotypes.@*Results@#There were G and C alleles in HLA⁃A rs3132682 locus , GG , GC and CC genotype. After adjusting for confounding factors in HLA⁃A rs3132682 locus , there was correlation between CC genotype and the risk of liver cancer compared with GG genotype (P < 0. 05) . Stratification analysis showed that compared with the population with CG + GG genotype , the Korean population with CC genotype increased the risk of liver cancer by 3. 331 times.@*Conclusion@#The single nucleotide polymorphism of HLA⁃A rs3132682 is correlated with the risk of liver cancer in Yanbian area.
RESUMEN
Objective:To explore the relationship between type I hypersensitivity reaction and the mechanism of the viral hepatitis B through the research of interleukin(IL-13 ) and prostaglandin(PGE1) levels in serum of patients with viral hepatitis B, and therefore, to provide new theory for the perfection of the immunological mechanism of hepatitis B, especially acute hepatitis B.Methods:Serum IL-13 and PGE1 levels were measured in 50 patients with viral hepatitis B and 35 normal cases using double antibody sandwich ELISA method. AST and ALT levels were studied using omni automatic biochemistry analyzer and those correlation with IL-13 and PGE1 were observed.Results:①The IL-13 and PGE1 levels of 10 acute hepatitis B were significantly higher than those of the normal cases; ②The IL-13 and PGE1 levels of 35 chronic hepatitis B were also significantly higher than those of the normal cases; ③The levels of IL-13 and PGE1 were significantly positively correlated with serum ALT and AST.Conclusion:IL-13 and PGE1 levels in patients with acute hepatitis B are most remarkably increased, and correlate with the damage of liver.
