应用聚合酶链反应检测孕妇尖锐湿疣（ＣＡ）组织、无ＣＡ孕妇宫颈分泌物、外周血及羊水、新生儿咽分泌物、脐血中人乳头瘤病毒（ＨＰＶ）感染及母婴传播。结果表明：ＣＡ组织中ＨＰＶＤＮＡ阳性率为９０．３２％，以ＨＰＶ６／１１型为主；无ＣＡ孕妇宫颈分泌物中ＨＰＶＤＮＡ阳性率为３５．７１％，以ＨＰＶ１６／１８型为主；孕妇血中ＨＰＶＤＮＡ阳性率为５７．６９％；母婴间经产道垂直传播率为４４．４４％，血性经胎盘传播传播率为６０％。说明ＨＰＶ不仅存在于ＣＡ组织中，还存在于无ＣＡ孕妇生殖道及外周血中，母婴间传播途径除产道外，还有胎盘传播
Cervical secretions, peripheral blood and amniotic fluid, neonatal pharyngeal secretions, human papillomavirus (HPV) infection and mother-to-child transmission in pregnant women were detected by polymerase chain reaction (PCR). The results showed that the positive rate of HPVDNA in CA tissue was 90.32%, which was mainly HPV6 / 11 type. The positive rate of HPV DNA in cervical secretions without CA was 35.71%, mainly HPV16 / 18; The positive rate of HPVDNA was 57.69%. The vertical transmission rate of mother-infant through the birth canal was 44.44%, and the bloody transmission rate of placental transmission was 60%. That HPV exists not only in CA tissue, but also in the absence of CA pregnant women reproductive tract and peripheral blood, mother-to-child transmission in addition to the birth canal, there are placental transmission
