神经上皮

Results: The findings on CT and MRI were as follows: 57 cases of Oligodendroglioma, 15 cases of Ganglioglioma , 5 cases of Dysembryoplastic neuroepithelial tumor , 3 cases of Pleomorphic xanthoastrocytoma .

结果：少枝胶质瘤47例，间变性少枝胶质瘤10例，节细胞胶质瘤15例，胚胎发育不良性神经上皮瘤5例，多形黄色细胞瘤3例。

The detection of Nestin expression contributes to correctly evaluate the malignant degree and biological behaviors and is an important clue to ascertain the pathological grades and prognosis of neuroepithelial tumors.

Nestin表达检测有助于正确评价神经上皮肿瘤的生物学行为和恶性程度，并可作为判断肿瘤病理级别和患者预后的重要依据。

Methods The clinical data of 46 patients (49 eyes) aged above 45 years with macular serous neuroepithelial detachment who have been diagnosed by binocular indirect ophthalmoscope and optical coherence tomography were retrospectively analyzed.

对年龄在45岁以上，双目间接检眼镜检查结合光相干断层扫描确诊为黄斑区浆液性神经上皮脱离患者46例49只眼的临床资料进行回顾性分析。

RESULTS:All the vascular endothelial cells of tumors were positive for Nestin. The percentage of Nestin positive cells was 9.5%-96.2% in the neuroepithelial tumors. The positive expression rate and staining intensity of Nestin+ cells were positively correlated with the tumor pathological grades.

结果： Nestin在肿瘤内皮细胞中均有阳性染色，而在神经上皮肿瘤细胞中阳性染色比例为9.5%～96.2%，且Nestin+细胞比例及染色强度与肿瘤的恶性程度正相关。

The study was done to compare the induction efficiency of human embryonic stem cells to neuroepithelial progenitor cells in human embryonic fibroblasts,mouse embryonic fibroblasts and feeder free systems.

中文摘要：［摘要］比较人胚胎干细胞在人胚胎成纤维细胞、鼠胚胎成纤维细胞饲养层和无饲养层3个诱导体系下形成神经上皮祖细胞的能力。

METHODS:Nestin expression was detected in 33 cases of neuroepithelial tumors using the immunocytochemical staining. The Nestin positive and negative cells were isolated by magnetic activated cell sorting. Nestin positive cells were culutered, identified, and induced to differentiate. The expression of Nestin protein was detected in Nestin+ cells by RTPCR.

采用免疫组化法检测神经上皮肿瘤组织中Nestin的表达情况，免疫磁珠法分选肿瘤组织中的Nestin+细胞，悬浮细胞培养法进行Nestin+细胞的增殖、分化与鉴定，RTPCR法检测Nestin蛋白在其中的活性表达情况。

The results showed that in the control and experimental groups, HMGB1 immunoreactivity was all diffusely distributed in the cytoplasm of neuroepithelial cells and mesenchymal cells surrounded the neural tube at 8,16 and 24 hours after water bath treatment.

将孕鼠随机分为实验组和对照组，分别于水浴处理后8、16、24、40、64 h（相当于胚龄第8、8.5、9、9.5、10.5 d）处死孕鼠，剖腹取鼠胚，制备石蜡切片，应用免疫荧光染色技术检测NTDs发生过程中HMGB1在神经上皮细胞中的表达变化。

Human embryonic stem cells can differentiate into neuroepithelial progenitor cells in both feeder containing and feeder free systems,yet feeder free system has a relatively lower inductive efficiency with part of undifferentiated embryonic stem cells.

人胚胎干细胞在有饲养层和无饲养层体系中均可诱导分化形成神经上皮祖细胞，但无饲养层体系的效率相对较低，且有未分化胚胎干细胞残余。

Objective To observe the of macular serous neuroepithelial detachment and the necessary auxiliary examination methods for the diagnosis.

曹绪胜，周海英，张风，周辉摘要：目的观察45岁以上患者发生黄斑区浆液性神经上皮脱离的疾病类型，探讨疾病诊断必要的辅助检查方法。

Objective To evaluate the morphological changes of retinal neuroepithelium of central serous chorioretinopathy by Fourierdomain optical coherence tomography.

目的 观察中心性浆液性脉络膜视网膜病变神经上皮脱离区在频域光相干断层扫描的图像特征。

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。
