胎儿

There were five cases of lung tumors with cystadenoma change, two cases of pulmonary sequestration, and two cases with lung tumor diminution.

结果 9例产前超声检查中发现胎儿肺部肿块；其中5例为胎儿肺囊腺瘤样改变；2例肺分离；2例肿块逐渐缩小。

Results An intracerebral echoless cyst could be visualized in all the three cases, in which" high-speed and low-resistance" blood signal could be detected by CDFI. There was direct communication between the vein of Galen and several basis cranii cerebral arteries without cerebral ventricle dilation. The dilated heart-breast rate could be visualized in all the three cases, two of which complicating with the dilation of superior vena cava and tricuspid regurgitation; two of which complicating with pleural fluid and abdominal dropsy; one of which complicating with edema of skin and polyhydramnios; one of which complicating with reversing blood signal of umbilical artery in diastolic phase.

结果 超声声像图显示3例胎儿在丘脑后下方、小脑上方有一无回声囊性结构，彩色多普勒超声提示无回声区内为高速低阻血流信号，与颅底动脉环间可见多条血管分支相通；脑室系统均未见扩大；胎儿心胸比增大，其中2例伴有上腔静脉内径增宽、三尖瓣反流；2例伴有胸腹水，1例全身皮肤水肿伴羊水过多，1例脐动脉舒张期血流反向。

Excitatory effect of caffeine, will stimulate increased fetal movement, and even endanger the growth of the fetus.

咖啡因具有兴奋作用，会刺激胎儿增加胎动，甚至危害胎儿的生长发育。

We have performed systematical studies on intrauterine transmission of hepatitis B virus and our studies suggested that HBV may occur through progressive infection of different placental layers until the virus reaches the fetoplacental circulation, which is the named "transplacental cellular traffic" except through placental tears with transfusion of infected maternal blood into the fetal circulation, which is the named "hematogenous transmission".

我室近年来对HBV宫内传播进行了系列研究，发现了胎盘在宫内传播中的作用，并提出了HBV宫内传播机制的假设：除血源性途径外，还可通过HBV在胎盘组织内的&细胞传递&途径，即HBV可以从母体蜕膜细胞通过&逐层转移&至胎儿绒毛毛细血管内皮细胞，导致胎儿感染。

Biotinylated lectins:UEA-Ⅰ, RCA-Ⅰ, DBA, PSA, PNA, BSL, LCA, WGA, ConA AND SBA were used as probes to identify lectin binding sites and to determine if lectin binding patterns change with age in the developing of human fetal esopha geal epithelium (8W, 14W, 20W, 28W and 32W).

采用十种生物素化凝集素UEA-I、DBA、PSA、B SL、PNA、LCA、RCA-I、SBA、ConA及WGA分别对8W、14W、20W 28W及32W的人胎儿食管上皮进行研究，以确定胎儿食管上皮在发育过程中凝集素的结合位点以及结合方式随年龄的变化。

In this study, Mono-nuclear cells containing hematopoietic stem/progenitor cells were isolated from umbilical cord blood of normal full-term deliveries, healthy adult and heterocellular HPFH patient bone marrow by density gradient centrifugation. After simple purification and expansion in vitro, MNCs were induced to erythroid cell differentiation using different culture systems and cytokines including Epo, IL-3 and GM-CSF.

本研究首先利用密度梯度离心方法，从正常成人和异细胞型遗传性胎儿血红蛋白持续存在综合症家系患者的骨髓组织、健康足月正常分娩胎儿脐带血中分离得到了含有造血干／祖细胞的单个核细胞(Mono-Nuclear Cell，MNC)，进行初步纯化及体外扩增后，组合使用Epo、IL-3、GM-CSF等细胞因子，将造血干／祖细胞向红系方向进行诱导培养。

This relationship keep the fetus inexclusive from the matrix which is very important to maintain the normal growth of the fetus.

这种关系使作为异物的胎儿不被排斥，对维持胎儿的正常发育有着极其重要的作用。

HBV transplacental transmission route may be realized by cell to cell transfer in placenta, which means that HBVs in maternal blood and/or intervillous space infect DCEC and/or DC and/or TC, then transmit to VMC, then to VCEC, and finally to fetus.

HBV经胎盘感染胎儿的路径可能是通过胎盘细胞至细胞的传递而实现的。即母血和/或绒毛间隙HBV→蜕膜毛细胞管内皮细胞和/或蜕膜细胞和/或滋养层细胞→绒毛间质细胞→绒毛毛细血管内皮细胞→胎儿。

fetal cystic lymphangioma can be diagnosed with ultrasonography,which is of an important clinical value in the management of pregnancy

超声可诊断胎儿水囊状淋巴管瘤，对临床医师评估胎儿预后、指导临床处置有重要的临床意义。

Most commonly, size discrepancy secondary to fetal macrosomia is associated with difficult shoulder delivery.

通常，胎儿身体尺寸比例失调也是引起肩难产的一个重要原因，仅次于巨大胎儿。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
