Significantly increased risks to first- and second-degree relatives for astrocytomas were identified for relatives of astrocytomas considered separately.

That said, pleomorphic xanthoastrocytoma with anaplastic features needs to be ruled out.

The pathology,clinical presentation,menifestation of CT and MRI, and imaging diagnosis and differentiant diagnosis of astrocytic tumors are precisely reviewed.

本文对各种星形细胞肿瘤的病理、临床、CT、MRI特征、诊断和鉴别诊断要点进行阐述。

Results All patients were for their epilepsy and hypophrenia,two patients had multiple angimyolipomain their one kidney,one patient had a tumor under endyma.

结果 5例患者均以智力低下、癫痫就诊，2例出现肾错构瘤，1例见巨细胞星形细胞瘤。

Postoperative pathological results revealed that 79 cases (86.8%) were low-grade gliomas, 4 cavernous hemangiomas, 4 anaplastic astrocytomas, 2 gliosis, 1 arteriovenous malformation, and 1 gliosarcoma.

术后病理结果示低级别胶质瘤79例(86.8%)，海绵状血管瘤4例，间变性星形细胞瘤4例，神经胶质增生2例，动静脉畸形1例，胶质肉瘤1例。

A 51 year old woman sought medical attention because of gradually increasing right hemiparesis and hemianopia. At craniotomy (8/90), left parietal anaplastic astrocytoma was found.

患者51岁，女性，主因进行性右侧偏瘫，偏盲寻医。90年8月接收开颅术，术中发现左颞页间变性星形细胞瘤。

This, however, is rarely achieved because of their infiltrative nature.

然而，因为星形细胞瘤浸润生长的特点很难做到。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
