Although an actie central nerous system is present by the eighth week of deelopment and a brainstem by the end of the first trimester (which could act as a rudimentary modulator of sensory information and motor actiity), Flower noted that the neocortex does not become a functional part of the neuraxis until at least mid-gestation when the thalamus (the major gateway for sensory input to the cerebrum) makes its first afferent contacts with the neocortex.

虽然在发育8周中枢神经系统即可有活性，在妊娠前三月结束时脑干具有活性（可充当感觉信息和运动功能的未完全发育的调制器），但是Flower表示，新皮质不会成为神经轴有功能的一部分，直到至少妊娠中期，丘脑（感觉传入大脑的主要通路）发挥其首先与新皮质系统输入联系的功能。

objective to evaluate the clinical value of early diagnosis and therapy of suspicious ectopic pregnancy by laparoscopy.methods the clinical data of 53 suspicious tubal pregnancy patients were analyzed retrospectively,who had received laparoscopic operation in our hospital from january 2003 to december 2005.results all cases received laparoscopic operation,none was transferred to traditional surgery during the operation.46 cases were diagnosed as tubal pregnancy during the operation with pathologic proof.preoperative diagnosis rate was 86.8%.the salpingecstomy were performed in the 32 cases.the salpingotomy were performed in the 7 cases.conclusion the laparoscopic operation is the best choice in the early diagnosis and therapy of suspicious ectopic pregnancy,and it gain time for conservative therapy.but not too early.

目的 评价可疑异位妊娠患者腹腔镜早期诊治的临床价值。方法收集2003年1月～2005年12月收治的经腹腔镜手术治疗的可疑输卵管妊娠患者53例资料进行回顾性分析。结果 53例手术均经腹腔镜完成，无1例中转，术中诊断输卵管妊娠的46例，术前诊断率86.8%，32例行输卵管切除术，7例行保守性手术。结论腹腔镜手术是早期确诊可疑异位妊娠患者的最佳选择，也为保守性治理赢得时间，但不宜操之过急。
