异常发育

She had had multiple atypical nevi, and one of two previous excisions had reportedly shown dysplastic changes.

她有多个典型的痣，两种以前曾报道显示表皮发育异常的变化。

Mechanical stress on the dysplastic hip has been widely described, but dynamic instability requires further evaluation.

在发育异常的髋上机械应力已被大量描述，但是动态不稳定性要求更进一步的评估。

Furthermore, we found that HPV-positive dysplastic and tumorigenic cervical lesions were characterized by high levels of EZH2 protein in vivo.

并且，研究发现，HPV阳性的发育异常的以及致瘤颈损伤以EZH2的高表达为特征。

Classification by histogenesis:(1) Primary tumor 6 679 cases: epitheliogenic 2 481 cases (37.15%), mesenchymal 753 cases (11.27%), lympho-hematopoietic 102 cases (1.53%), neurogenic 1 542 cases (23.09%), congenital abnormal embryogenetic 1 767 cases (26.46%), uncertain resource tumor 34 cases (0.50%).(2) Secondary tumor 13 cases;(3) Metastatic tumor 9 cases;(4) Non-tumor lesion 1 972 cases.

按组织发生学分类：（1）原发性肿瘤6 679例（77.01%），其中上皮组织肿瘤2 481例（37.15%），间叶组织肿瘤753例（11.27%），淋巴造血组织肿瘤102例（1.53%），神经组织肿瘤1 542例23.09%），先天胚胎发育异常肿瘤1 767例（26.46%），不明来源肿瘤34例（0.50%）；（2）继发性肿瘤13例(0.15%；（3）转移性肿瘤9例(0.10%)；（4）非肿瘤性病变1 972例(22.74%)。

Embryologically, the abnormality most likely develops at gestational weeks four to eight. It is hypothesized that impaired venous outflow, caused by loss of normal connections between cortical veins and dural and calvarial circulation, results in persistent, primitive vascular plexus.

胚胎学上，发育异常最可能发生在孕期的第4-8周，其发病机制被认为是静脉流出受损，这是由于皮层静脉与硬膜及颅盖静脉循环之间的正常连接出现障碍，导致原始血管持续存在。

It is known that cardiovascular risk factors, smoking, fibromuscular dysplasia, or moyamoya disease are frequently found as an aetiological factor in patients with bilateral ICA occlusion, whereas essential thrombocytaemia, giant cell arteritis, and BD are among the very rare causes.

众所周知，双侧颈内动脉闭塞的常见病因为心血管危险因素、吸烟、纤维肌性发育不良、Moyamoya病/烟雾病/脑底异常血管网病等，而特发性血小板增多症（essential thrombocytaemia， essential thrombocythemia， ET）、巨细胞性动脉炎、白塞病则为非常罕见的原因。

Morphology of sexual reproduction abortion in'High Noon', a distant hybridization cultivar of tree peonies(P.delavayi var. lutea×P. suffruticasa), was systematically investigated with light microscopy and cross. The results indicated that:(1)The stamens matured earlier than the gynoecia and pollens dispersed at the early stage of anthesis but the rate of normal 2-celled pollens were merely 2.41%.

采用光镜和杂交等方法对牡丹远缘杂交一代品种'正午'有性生殖败育进行系统形态学观察发现：(1)雄蕊较雌蕊先成熟，初花期即散粉，正常2-细胞花粉仅占2·41%，且花粉在多种培养液中、在自身和其它两种柱头上均不萌发；柱头在谢花期大量分泌粘液，进入最佳授粉状态；(2)同一胚珠中多个大孢子母细胞减数分裂高度不同步，胚囊发育与受精延迟，部分胚乳游离核在细胞化时期分裂异常；(3)自花及品种内异花授粉不结实，天然授粉结实率为0·053‰~0·130‰。

Purpose: To analyse CT manifestations of gyral malformations of neuronal migrationl anomaly.

目的：分析神经元移行异常所引起的脑回发育畸形的CT表现。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
