目的；了解HBsAg阳性孕妇及其新生儿PBMC HBV感染状况。方法：采用原位杂麦（ISH）技术检测114例孕妇和新生儿PBMC涂片中HBV DNA。结果：114例HBsAg阳性孕妇及其新生儿PBMC HBV DNA的检出率分别为28．07％（32／114）和32．46％（37／114）；HBsAg阳性孕妇与其新生儿之间的PBMC HBV感染存在一致性（Kappa=0．52，P〈0．01）。结论：证实HBsAg阳性孕妇与其新生儿之问的PBMC HBV感染存在一致性。

英文摘要：

Objective：To observe the status of HBV infection in peripheral blood mononuclear cells （PBMC） from the HBsAg-positive mothers and their neonates. Methods;In situ hybridization （ISH） was used to detect HBV DNA in PBMC smear from 114 HBsAg-positive mothers and theirs newborns. Results：The positive rates of the PBMC HBV infection of the mothers and their neonates were 28. 07% and 32.46%, respectively. There was an agreement of the HBV infection status between the mothers and their newborns （Kappa=0. 52, P〈 0.01）. Conclusion：The result suggests that the HBV infection status from the mothers agrees with that from their newborns.
