摘要
目的探讨慢性乙肝病人血清HBV DNA前C基因区nt1896的变异情况及其与HBV DNA水平及转氨酶(ALT)关系。方法将172例慢性乙肝患者分为两组:大三阳组(106例)和小三组(66例)。检测ALT、HBV DNA及前C区nt1896的变异情况。结果大三阳组与小三阳组HBV DNA阳性率有显著差异(P<0.05),nt1896变异率无显著差异(P>0.05)。小三阳患者中ALT升高组(>40 U/L)HBV DNA(+)患者nt1896变异率100%,而ALT正常组HBV DNA(+)患者nt1896变异率30%(3/10)(P<0.05)。结论大三阳和小三阳慢性乙型肝炎病人都存在较高的前C区nt1896变异率(P>0.05)。前C区nt1896变异可能是影响HBV DNA复制的一个因素。
Objective To detect chronic hapafifis B patients hapatitis B virus(HBV) precore region mutations at nuclearfide 1896(nt-1896) and to devdop the rehtionship between the results and the amnotransferase (ALT) with the level of DNA.Methods To divided the patients into two groups: HBsAg( + )/HBeAg( + )/HBcAb( + ) group and HBsAg( + )/HBeAb( + )/HBcAb( + ) group.Test the patients' liver function, HBV DNA and study the mutation at nt-1896 further. Results There was marked difference betwecn two groups with HBV DNA( + ) rate( P 〈 0.05 ), but no difference with nt- 1896 mutation rate( P 〉 0.05). The patients with HBsAg( + )/HBOAb( + )/HBOAb( + ),ALT higher than normal range group mutation rate was 100% (15/15),ALT normal range group mutation rate was 30% (3/10) ( P 〈 0.05 ). Conclusion Both groups patients of chronic hapatitis B had a high mutation rate at nt1896( P 〉 0.05).Maybe the mutation at nt1896 in precore is one of the factors which affect HBV DNA copy.
