解脲支原体感染与胎膜早破的关系

用ＰＣＲ技术同时检测３０例胎膜早破（ＰＲＯＭ）和２２例非胎膜早破（ＮＰＲＯＭ）的新生儿咽吸出物、胎盘组织及脐静脉血清中解脲支原体（Ｕｎ）感染率，发现ＰＲＯＭ组咽吸出物Ｕｕ阳性率为３６．６７％，ＮＰＲＯＭ组咽吸出物Ｕｎ阳性率为９．０９％，差异显著（Ｐ＜０．０５）。胎盘，脐血中Ｕｕ阳性率于两组间无显著差异，ＰＲＯＭ产妇中，新生儿咽吸出物Ｕｕ＋的平均ＩＭＲＤ为４５．０８小时，Ｕｕ－的平均ＩＭＲＤ为２８．３４小时，差异显著（Ｐ＜０．０５）；而孕妇胎盘组织、脐血Ｕｕ＋组与Ｕｕ－组平均ＩＭＲＤ显著差异。结果表明羊水解脲支原体感染能导致胎膜早破。

Detection on CT of 530 newborns throat swab by nested PCR.

We have detected CT DNA of 530 cases of newborn throat swab by using a sensitive ,specific and simple nested PCR technique.The results showed that the total detected incidence of CT DNA in 530 samples was 15 4%,among them ,the cases of vagina birth made up 14 1%,while the cases of caesarean birth occubled 1 3% and the detected rate in the newborns form urban mother was 6 1% of total 15 4%,while 9 3% was the positive rate in the cases from rural mother.
