妊娠前的

Rare cases of embryopathy, including aplasia cutis, have been reported with the use of MMI during pregnancy, whereas no such cases have been reported with PTU use. Thus, PTU may be more appropriate for patients with Graves' disease who are in their first trimester of pregnancy.

已有报道指出，妊娠期间使用MMI治疗可偶发生育缺陷等胚胎病，而PTU未见此类相关报道，故PTU可能更适用于治疗处于妊娠期前3个月的Graves病患者。

Some evidence indicates that compared with gemeprost, misoprostol may increase laxation and dilation rate of the cervix, shorten gravid exclusion time, improve the rate of complete abortion and make the laxation and dilation range of the cerix larger than gemeprost before the first and second-trimester abortive surgery.

与吉美前列腺素比较，孕早期人工流产术前使用进口米索前列醇的宫颈扩张率和宫颈扩张度等更优；孕中期人工流产术前使用进口米索前列醇经宫颈内给药，可有效提高完全流产率和缩短妊娠物排除时间。

"In this study, antepartum dental radiography in pregnant women was associated with an increased risk for a LBW infant, especially a TLBW infant," the authors write."Since women may not always be aware of their pregnancy status, it may not be possible to eliminate all dental radiography during pregnancy, but if this goal could be achieved and if the identified association is causal, the prevalence of TLBW infants could be reduced by up to 5%.... The notion that very low-dose radiation exposures to nonreproductive organs in expectant mothers are safe needs to be investigated further."

研究人员表示，在这项研究中，怀孕期妇女分娩前牙科X光摄影与LBW新生儿的风险增加联结在一起，特别是TLBW，由於妇女不能总是注意到她们的妊娠状态，也不可能在怀孕期间取消所有的牙科X光摄影，但如杲这个目标能达成，而且被识别的联想是偶然的，则TWBL新生儿的盛行率能依5%减少；此外，在妊娠妇女中，对非生殖器官极低剂量辐射曝露，是须进一步研究的安全需求概念。

There were different results between two groups that delivered before and after 35 pregnant weeks, and obstetrical treatment could affect fetal and maternal prognosis.

妊娠期高血压疾病患者在妊娠35周前、后分娩具有不同的妊娠结局，产科处理影响其母儿预后。

Obstetrical records of 12 224 primiparae in obstetrical wards of 8 hospitals in Beijing were reviewed,and each primipara was interviewed by questionnaire before discharge from hospital during May 1992 to April 1993.1 272 cases exposed to occupational noise during pregnancy were selected as the exposed group,and 9 260 cases of unexposed to any occupational hazards as the control group.

为探讨应用医院产科资料进行职业性有害因素对妊娠经过和妊娠结局影响研究的价值，对北京市8所医院产科病房自1992年5月至1993年4月期间住院分娩的12 224名初产妇，进行了应用产科记录资料，并于产妇出院前做个案随访，进行问卷调查的方法收集资料。

Hydrosalpinx is detrimental to the outcome of IVF-ET and may cause the increase of abortion,appropriate procedure should be adopted to deal with the problem before the IVF-ET and may improve the outcome of IVF-ET and may decrease the abortion rate.Compared with the salpingectomy,the proximal tubal ligation with distal tubal salingostomy may be a better option in this situation and it may cause less interference to the ovarian function.

输卵管积水对IVF-ET有不良影响，增加了流产率及异位妊娠率，在IVF-ET前对输卵管积水进行适当的处理有助于提高临床妊娠率，降低流产率；与输卵管切除术相比，输卵管近端结扎伞端造口术对卵巢功能影响较小，不增加流产率及异位妊娠率。

Results about the cases confirmed by the surgery and pathologic examination, the diagnostic accuracy of preoperative ultrasonography was 89.3%. two cases were misdiagnosed as pelvic inflammatory disease mass and the septus uterus with one side intrauterine pregnancy, three cases of ectopic pregnancy were not accurately positioned, and two cases of cornual pregnancy and tubal pregnancy were mutual misdiagnosis.

结果 在我院经手术及病理检查报告证实诊断的37例宫角妊娠及29例间质部妊娠，术前超声诊断准确率为89.3％，有2例术前超声误诊为盆腔炎性包块及纵隔子宫一侧宫腔妊娠，有3例超声诊断为宫外孕未准确定位，另有2例宫角妊娠与间质部妊娠相互误诊。

The lower pregnancy rate was found in Group C,the highest abortion rate and ectopic pregnancy rate were found in Group C was 21.15% and 7.69% repectively,and was statistially different from that in control group (P.05).Conclusion Hydrosalpinx is detrimental to the outcome of IVF-ET and may cause the increase of abortion,appropriate procedure should be adopted to deal with the problem before the IVF-ET and may improve the outcome of IVF-ET and may decrease the abortion rate.

输卵管积水对IVF-ET有不良影响，增加了流产率及异位妊娠率，在IVF-ET前对输卵管积水进行适当的处理有助于提高临床妊娠率，降低流产率；与输卵管切除术相比，输卵管近端结扎伞端造口术对卵巢功能影响较小，不增加流产率及异位妊娠率。

Uterine obstruction of venous return can produce prearrest hypotension or shock and in the critically ill patient may precipitate arrest.1,2In cardiac arrest the compromise in venous return and cardiac output by the gravid uterus limits the effectiveness of chest compressions.

在怀孕20周以后，妊娠子宫挤压下腔静脉和主动脉，使静脉回流和心输出量受阻。子宫静脉回流受阻会导致停跳前高血压或休克，对病情危重的患者促进心跳停止[1，2]，同时，妊娠子宫还限制肺的舒张。
