胎儿

Results There were fetal type in 12 cases, embryonal type in 7 cases, anaplasia type in 3 and mixed type in 2. The cytoplasmic postive expression of CK, AFP, S-100 protein and Vimentin of epithelial tumor cells were found in 14, 10, 9 and 6 cases respectively. Positive staining of CEA, P53 and P16 of nuclei of epithelial tumor cells were found in 11, 9 and 7 cases respectively.Among the 12 cases who underwent surgical excision, 8 patients with fetal type survived over 5 years. Conclusions This study suggests that immunoreaction of hepatoblastomas are different in the histological subtypes.

结果 胎儿型12例，胚胎型7例，间变型3例和上皮间叶混合型2例；细胞角蛋白、甲胎蛋白、S-100蛋白和波形蛋白在肿瘤上皮细胞浆的表达分别为14例、10例、9例和6例，癌胚抗原、P53和P16蛋白在细胞核中的表达分别是11例、9例和7例；手术切除肿瘤12例中8例生存期超过5年者均为胎儿型。

Purpose: To investigate the difference of cordis structure between anencephalus and normal foetus,and to collect numerical data of morphology for the study of featus anomalies.

目的：探讨无脑儿与正常胎儿心脏结构的差异，为畸形胎儿的心脏发育研究提供形态学方面的资料。

To anencephalus the hypophysis and nervous system develop defectively result in undevelopment of suprarenal gland. Thoracogastrodidymus develops more slowly than normal fetus.

无脑儿因脑垂体、神经系统发育障碍，而致肾上腺不发育；联体畸形胎儿肾上腺发育较同龄正常胎儿迟缓。

Result: Undevelopment of the anencephalus. Thoracogastrodidymus develops defectively. Ectrosyndactylia develops normally.

结果：无脑儿肾上腺未发育；胸腹壁联体畸形胎儿肾上腺发育欠充分；并指畸形胎儿肾上腺发育正常。

A 28-years-old primigravida was referred at 31st week of gestation for a targeted ultrasound examination following visualization of a severe hydramnios. Fetal biometry was consistent with gestational age.

一28岁初产妇，孕31周时定向超声检查发现羊水明显的增多，胎儿生物学检查符合孕周，为男性胎儿。

A 28-years-old primigraida was referred at 31st week of gestation for a targeted ultrasound examination following isualization of a seere hydramnios. Fetal biometry was consistent with gestational age.

All cases were verified by the DNA of chorion amnionic fluid and neonatal cord blood.

PCR扩增技术，检测游离在孕妇血浆内的无细胞胎儿DNA，能在孕期鉴别胎儿性别，尤其是对早期某些选择性遗传性疾病的非创伤性产前诊断意义重大。

Embryonic germ cell lines were isolated and cloned from gonad,gonadal ridge,analogue or the surrounding tissues of 9.5～13.5 days postcoitum mouse fetuses.Primordial germ cells were co-cultured with mouse embryonic fibroblasts obtained from the same conceptus.

自交配后9.5～13.5 d小鼠胎儿生殖嵴/腺或其类似物及周围组织，采用与其同源胎儿成纤维细胞共培养的方式分离克隆到具小鼠ES细胞诸多特征的胚胎生殖细胞系。

Objective:To investigate the effect and the clinical value of congenital heart disease.

目的：探讨胎儿超声心动图在诊断胎儿先天性心脏畸形中的作用及其临床意义。

Mild cervical erosion have little effect on the fetus can be post-natal treatment:(1) electric iron treatment (2) Cryosurgery (3) laser treatment (4) infrared coagulation treatment of 2, pregnant women, iodine deficiency can affect fetal development, neonatal severe cases of "cretinism", the best iodine supplement food for the seafood.

轻度宫颈糜烂对胎儿影响不大，可于产后进行治疗：(1)电熨治疗(2)冷冻治疗(3)激光治疗(4)红外线凝结治疗2、孕妇缺碘可影响胎儿的发育，严重者新生儿出现"克汀病"，最好的补充碘食品为海产品。
