RM has special morphological characteristics; it should be differentiated from gemis tocytic astrocytoma, atypical teratoid/rhabdoid tumor, and malignant melanocytoma.

RM有特殊的组织学特点，应注意与胖细胞型星形细胞瘤、非典型畸胎样瘤/横纹肌样瘤、恶性黑色素瘤等鉴别。

Results The supratentorial lesions involved the occipital lobe in 4, frontal lobe in 3, fronto-occipital lobe in 2, temporo-occipital lobe in 3, lateral ventricle in 1 case and the saddle region in 1. All the lesions were large in volume and most of them presented heterogeneous signals in MRI. Of the 14 cases, 12 showed cystic degeneration and necrosis, 2 had hemorrhage and 6 showed signs of emptied small blood vessels. Twelve cases had heterogeneous enhancement and 2 had moderate enhancement. Pathologically, 10 cases of neuroblastomas were identified, along with 3 ganglioneuroblastomas and 1 atypical rhabdoid tumor.

结果 病灶位于顶叶4例，额叶3例，枕顶叶2例，颞枕叶3例，侧脑室1例，鞍区1例，病灶普遍较大，病灶绝大多数信号不均匀，病灶内可见囊变／坏死（12例）、出血（2例）、流空小血管影（6例），增强后病灶呈明显不均匀强化（12例），中等强化2例；神经母细胞瘤10例，节细胞神经母细胞瘤3例，非典型横纹肌样瘤1例。

To date, there have been a few clinical trials exploring the efficacy of NMDA enhancers as adjuvant therapy. For instance, D-serine (an endogenous agonist of the NMDA-glycine site) and sarcosine (N-methylglycine, an endogenous glycine transporter I inhibitor) are not only well-tolerated but also synergistic in improving positive, negative symptoms and cognitive function in chronic patients receiving typical or atypical antipsychotics. We just completed the first trial applying NMDA enhancers in acutely exacerbated schizophrenia patients with collaboration with Harvard University, and the results showed that sarcosine was superior to D-serine in efficacy.

目前已有将NMDA促进剂作为辅助用药的临床研究，例如，D-serine (一种内生性NMDA-glycine site致效剂)、sarcosine (即N-methylglycine，一种内生性glycine transporter I 抑制剂)等，结果显示它们不但安全，且能加强传统及新一代抗精神病剂对慢性患者活性、负性症状及认知功能的疗效；我们日前与哈佛大学合作完成目前唯一将NMDA促进剂用於急性患者的研究，结果发现，sarcosine的疗效又优於D-serine。

Objective To study the relationship between mechanism of non-gene regulation apoptosis and prognosis of typical medullary carcinoma,atypical medullary carcinoma and scirrhous carcinoma.

Testing also was conducted to evaluate whether the persistent seronegativity was attributable to infection with an atypical virus or to lack of immune competence.

A large genus constituting the order Sphagnales: atypical mosses of temperate bogs with leaves that can hold much water.

In a statement issued on March 10, the FDA said that at this point, based on data it has reviewed, there is not a "clear connection" between bisphosphonate use and the risk of atypical subtrochanteric femur fractures.

FDA在3月10日发布的声明中说，目前，根据其所审查的数据，未发现使用双膦酸盐与不典型性股骨转子下骨折风险之间存在&明显关联&。

不典型增生和早期胃癌组织中表达的阳性率分别为70％和41.7％。

Although classic neuroimaging features of RPLS with involvement of the posterior head regions are easily recognized, features that may generally be regarded as atypical were often present in our patients, such as significant anterior involvement, cortical lesions, recurrent RPLS episodes, foci of permanent injury, hemorrhage into lesions, and unilaterality (Figure 1). High signal intensity on T2-weighted image lesions can occur in regions other than the parieto-occipital areas, frequently involving the frontal lobes, basal ganglia, thalami, or brainstem.

可逆性后部白质脑病综合征典型的神经影像学表现为大脑后部受累，尽管这一点很早就被公认；但可逆性后部白质脑病综合征不典型的神经影像学表现，在本文的患者中则更常见，如：大脑前部明显受累、皮层出现病灶、可逆性后部白质脑病综合征再次发作、脑永久性损伤灶形成、病灶内出血、仅见单侧病灶（图1）；T2像常可于额叶、基底节区、丘脑、脑干等顶-枕叶以外的区域见高信号病灶。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
