胎儿

This is no feature of trisomy 21,though some Down syndrome fetuses may not have detectable abnormality on routine scam.

这不是21三体综合征的特点，尽管有些唐氏综合征胎儿可能不会对日常检出异常。

Methods To analyze retrospectively the ultrasonography of 8 cases which had been karyotyped to be trisomy 18 by fetal blood sampling or amniocentesis.

对脐血或羊水染色体核型分析确诊为18三体综合征的8例胎儿超声声像图进行回顾性分析。

Over 200 types of cells have been made. Muscles and nerves are twitching.

胎儿身上产生了超过200种不同形态的细胞，肌肉和神经系统也在剧烈变化。

Even in an ultra sound examination, we couldn't get any picture of a fetus.

即使在超声波检查下，我们也没能得到胎儿的影像。

Objective: To illuminate the molecular mechanism and provide basic data and methods for early diagnosis, prevention and treatment of NTDs, studies were made on histopathology, ultramicroscopic pathology, cytogenetics, gene expression of molecular genetics and intervention experiment through maternal folic acid supplyment.

目的 研究NTDs胎儿组织病理学和超微病理学改变、细胞遗传学的染色体改变及分子遗传学的基因表达改变，通过增补叶酸干预实验，为探讨NTDs的分子发病机制、对NTDs的早期诊断和防治提供基础资料和方法。

The discovery of histopathology and ultramicroscopy was that cerebral cortex was agenetic, the structure of six layers was absent.

结果 1.NTDs胎儿的大脑皮质发育不完全，没有形成大脑皮质的6层结构，未见明显的神经细胞形成。

To isolate mononuclear cells from foetus umbilic cord blood, After MNCs were incubated in the presence of APS group (APS 200 mg·L-1) and control group for 24 h,the cells were stimulated with Epo（5 IU/mL） for 0,2,5,30 min; STAT5 was measured by ICC and laser confocal scanning microscope, JAK2、STAT5 in nucleus and cytoplasm were measured by western-blotting-ECL in each group at different groups.

分离纯化胎儿脐带血单个核细胞，在常规体外培养体系加入APS（200 mg·L-1）作用细胞24 h，促红细胞生成素分别刺激0，2，5，30 min，免疫细胞化学与激光共聚焦显微镜观察细胞STAT5的表达；Western-blotting-增强化学发光法检测细胞JAK2与浆和核中STAT5的表达。

METHODS: Ureaplasma urealyticum detection was performed in 16 samples of the umbilic blood of the malformed fetuses, sperms of the father, and cervical mucus of the mother who conceived the malformed fetus.

对16例畸形胎儿脐带血，畸形儿父亲的精液和异常妊娠产妇的宫颈黏液或阴道分泌物进行解脲脲原体分离。

Objective:To study the diagnostic value and clinical significance of B-ultrasound examination in diagnosis of circular of umbilical cord.

目的：讨论 B超检查对胎儿脐带绕颈的诊断价值及临床意义。

Methods The fetal umbilicus venous endothelial cells were isolated and cultured.

材料和方法：胎儿脐静脉血管内皮细胞的分离与培养。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
