无脑

RESULTS: Thirty-two cases were anencephalia, 31 hydrocephalus, 4 hydroancncephalus, 11 neningocele or encephalomeningocele, 25 spinal meningocele with myeloschisis, 12 Dandy-Walker deformity, 11 schizencephaly of forebrain and 22 choroid plexus cyst among the 148 fetuses. There were different expressions in various CNS deformities, which were correlated with abnormal development of embryo.

结果：148例中枢神经系统畸形胎儿中，无脑儿32例，脑积水3l例，积水性无脑4例，脑膜或脑脑膜膨出11例，脊柱裂脊膜膨出者25例，Dandy-Walker畸形12例，前脑无裂畸形11例，脉络丛囊22例，不同类型的中枢神经系统畸形有不同声像图表现，并与其胚胎发育过程异常相关。

In anencephaly there is absence of the cranial ault with secondary degeneration of the brain.

无脑畸形表现为缺乏颅顶和脑的继发性变性。

As in anencephaly, the fetal cranium is absent; howeer, unlike in anencephaly, brain tissue is always present Fig.

和无脑畸形一样，胎儿无头盖骨；但与无脑畸形不同的是，脑组织始终存在（图10-38）。

The hypothesis of a continuum of findings between exencephaly and anencephaly is supported by the obseration of residual brain tissue in about one third of cases of anencephaly(52) see Fig.

约1/3的无脑畸形病例中有残留的脑组织，这个观察资料支持露脑畸形和无脑畸形之间是连续病变表现的假设（见图10-37A-B，图 10-37C和10-38）。

The analyses confirm 7 cases with agyria, 5 with pachygyria of bilateral cerebral hemisphere and 3 with limited pachygyria of unilateral hemisphere.

结果显示：CT、MRI显示无脑回畸形 7例，双侧全大脑半球的巨脑回畸形 5例，单侧大脑半球的局限性巨脑回畸形 3例。

Between 6th and 14th weeks afteconstricted bilateral renal arteries, the blood pressure in the majority of RHRSP with cerebral infarction was obviously higher than in RHRSP without cerebral infarction (28. 8±2. 24kPa～32. 3 ±2. 88kPa, 26. 2±2. 01～28. 3±2. 33kPa respectively). Severe hyalinosis, fibrosis, wall hypertrophy, lumen stenosis, and even microaneurysm formation in cerebral small arteries in RHRSP with cerebral infarction were found, while slight to mild arteriolosclerosis in RHRSP was found without cerebral infarction.

本实验发现，RHRSP在经受不同水平的低血压后，产生脑梗塞的大多数（32/38只）在肾动脉狭窄术后第六周至第十四周，血压为28.8±2.24 kPa～32.3±2.88 kPa（216±17mmHg～242±22mmHg），显著高于无脑梗塞的RHRSP，并且发现这些RHRSP的脑内小血管呈严重的透明样变、纤维素样变性，管壁增厚，管腔狭窄，部分有微动脉瘤形成；而无脑梗塞的RHRSP的血压为26.2±2.01kPa～28.3±2.33 kPa（200±15mmHg～212±17.5mmHg），其脑内小血管呈轻至中度的动脉硬化改变。

Week. Conclusions The S1 area brain glioma model established by this method in rats had the same characters as human brain glioma. The tumor growth period was short and the subsisting period was stable without extracerebral metastasis and extracranial extension. This model is suitable for laboratory and treatment study of brain gliomas.

该方法建立的S1区脑胶质瘤模型具备与人脑胶质瘤生长相似的特性，肿瘤形成时间短，生存期稳定，且无脑外转移和颅外扩散，适合各种脑胶质瘤实验治疗研究。

Moreoer, in lissencephaly, an absence of gyri and sulci and occasionally entriculomegaly may be noted.

此外，在无脑回中，可以看看见缺乏脑沟和脑回，偶尔可见脑室扩大。

The risk factors for hematencephalon were analysed inchided CpIgG, aging, male, smoking, diabetes, hypertension, hyperlipidemia, mental labor and a high body mass index.

所有个体分为有、无脑出血，有、无脑出血危险因素（CpIgG抗体、年老、男性、吸烟、糖尿病、血脂紊乱、高血压、较少体力劳动和体重指数），比较有、无脑出血患者各种危险因素差别；并应用logistic回归分析，得出调整比值比值，用于评估Cp对脑出血的危险性。

Lissencephaly is a term used to described a brain with absent or poor sulci formation.

无脑回这个术语用于描述无或只有很少脑沟形成的脑。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
