摘　　要：目的了解乙型肝炎病毒表面抗原(HBsAg)阳性孕妇及其新生儿外周血乙型肝炎病毒(HBV)的感染状况。方法酶联免疫吸附试验(ELISA)法检测新生儿外周血HBsAg;巢式聚合酶链反应(nPCR)检测孕妇及其新生儿外周血HBV-DNA;选择性聚合酶链反应(sPCR)检测孕妇及其新生儿外周血单个核细胞(PBMC)中HBV-DNA,三项指标任一项阳性即判定为新生儿HBV宫内感染。结果HBsAg阳性孕妇血清HBV-DNA阳性率为43.1%(53/123),PBMCHBV-DNA阳性率为30.8%(37/123);新生儿血清HBsAg阳性率为6.5%(8/123),HBV-DNA阳性率为19.5%(24/123),PBMCHBV-DNA阳性率为26.0%(32/123)。新生儿任一项阳性者50例,合计宫内感染率40.6%(50/123)。结论检测PBMCHBV-DNA对血清中HBV-DNA检测进行补充,可以比较准确地反映HBsAg阳性孕妇新生儿宫内HBV感染的状况。Objective To learn the HBV-infection status of HBsAg-positive pregnant women and their newborns. Methods HBsAg was determined by enzyme-linked immunosorbent assay (ELISA); HBV-DNA was determined by nested PCR; PBMC HBV-DNA was determined by selected PCR; The newborns were intrauterinely infected if any one of the three markers showed positive. Results HBV-intrauterine infection rate was 43.1% for HBV-DNA and 30.8% for PBMC HBV DNA in HBsAg-positive pregnant women. HBV-intrauterine infection rate was 40.6%. HBV-intrauterine infection rate was 6.5% for HBsAg in serum, 19.5% for HBV DNA and 26.0% for PBMC HBV-DNA in newborns. Conclusion The detection of PBMC HBV is an important complement to the detectin of HBV-DNA in peripheral blood. It could be used for the aim of reflecting the the HBV-infection of HBsAg-positive pregnant women's newborns.
