Methods.. A total of 46 coses of pregnant women who suffered from HBV were divided into HBeAg ( + ) and HBeAg ( -) groups. HBV-DNA in serum and peripheral blood mononuclear cells (PBMC-) of 46 cases of pregnant women before delivery was detected by polymerase chain reaction (PCR). After placenta being delivery, HBV-DNA in serum and cord blood mononuclear cells (CBMC) was also detected by PCR. Results.. The total of positive rates of HBV-DNA in serum and PBMC of pregnant women with hepatitis B were 69. 57% (32/46) and 41. 30% (19/46). The positive rates of HBV-DNA in serum of cord blood and CBMC were 56. 52%(26/46) and 21. 74% (10/46) respectively. Among them, the positive rates of HBV-DNA in serum and PBMC of pregnant women with HBeAg ( + ) were 100. 00% (25/25) and 60. 00% (15/25) respectively. The positive rates of HBV-DNA in serum of cord blood and CBMC were 88. 00% (22/25) and 32. 00% (8/25) respectively. The positive rates of HBV-DNA in serum and PBMC of pregnant women with HBeAg (-) were 33. 33% (7/21) and 19.05% (4/21) respectively. The positive rates of HBV-DNA in serum of cord blood and CBMC were 19. 05%(4/21) and 9. 52% (2/21) respectively. The positive rates of HBV-DNA in serum of cord blood and CBMC of newborns were higher in the group of pregnant women with HBeAg ( + ) than those in the group of pregnant women with HBeAg ( -) (P<0. 01 and P<0. 05). There was no HBV-DNA in serum, PBMC and CBMC of normal pregnant women and normal neonates. Conclusion: The intrauterine transmission of HBV can be existent and its transmission way not only can be induced by serum but also can be induced by PBMC. The way of intrauterine transmission of HBV induced by PBMC was concealed. The dangerous possibility of intrauterine transmission is higher in the pregnant women with HBeAg (+) than that in the group of pregnant women with HBeAg ( -).展开更多
