星形细胞瘤

Objective To investigate the significance of p16 in survival analysis of patients with astrocytoma.

Cellular heterogenesis of gliomas shows close relationship with the progression of the tumors. A further study of the tumor differentiation may bring about an active effect on the therapy and prognosis of the disease.

星形细胞肿瘤在不断演进的过程中，其异质化的组织学分化特征也不断明显，进一步研究胶质瘤的组织学分化特征将会对胶质瘤的临床治疗及预后产生积极影响。

Methods We reported a case of PXA located in the cerebellum of a young adult in view of its extremely unusual location. Morphologic observation, immunohistochemical staining using DAKO EnVision system , histochemical stains including hematoxylin eosin and Gordon Sweet's reticulin methods were used.

采用免疫组织化学DAKOEnVison法、组织化学网质纤维染色和HE染色及形态学观察的方法，报道 1例极罕见于年轻人小脑的多形性黄色星形细胞瘤，探讨其临床病理特点。

Results Tag was found in all of 8 ependymomas, 2 choroid plexus papillomas, 2 human glioma cell lines, 90% of pituitary adenomas (9/10), 73% of astrocytomas (11/15), 70% of meningiomas (7/10), 50% of glioblastomas multiforme (4/8), and 33% of medulloblastomas (2/6). None of the 8 normal brain tissues were positive for Tag, nor were 5 oligodendrogliomas and 1 pineocytoma.

结果 Tag在8例室管膜瘤、2例脉络丛乳头状瘤及2株人脑胶质瘤细胞系中全部表达；垂体腺瘤Tag阳性率为90%(9/10)，星形胶质细胞瘤73%(11/15)，脑膜瘤70%(7/10)，多形性胶质母细胞瘤50%(4/8)，髓母细胞瘤33%(2/6)；5例少枝胶质细胞瘤、1例松果体瘤及8例正常人脑组织无Tag表达。

Objective: To investigate the clinical usefulness of DTI multiple parameter and diffusion tenser tracting in astrocytomas.

目的：探讨DTI多参数综合分析及DTT技术在星形细胞瘤分级、术前计划制定、术后疗效评价中的应用价值。

Objective To investigate the clinical usefulness of DTI multiple parameter and diffusion tenser tracting in astrocytomas.

目的 探讨磁共振扩散张量成像多参数综合分析及扩散张量纤维束成像在星形细胞瘤临床分级中的应用价值。

the result suggested that the age pathology grade and histologyical types were all involved in the astrocytoma progression.

星形细胞瘤恶性进展与年龄、肿瘤的病理分级和组织类型有关。

Objective To explore the value of diffusion weighted imaging in the differential diagnosis between viral encephalitis, cerebral infarctions and low grade astrocytomas.

目的探讨扩散加权成像对病毒性脑炎、脑梗死和脑低级星形细胞瘤的鉴别诊断价值。

A DNA vectorbased RNAi technology to suppress gene expression in mammalian cells〔J〕.Proc Natl Acad Sci U S A,2002;99(8):551520.12 Konnikova L,Kotecki M,Krugerm M,et al.

Konnikova〔12〕报道在星形胶质细胞瘤细胞株中沉默STAT3基因的表达后，会抑制肿瘤细胞的增殖并导致细胞凋亡。

Methods Immunohistochemical technique was used to detect the expression of VEGF-B, VEGF-C and MVD in 73 cases with astrocytoma.

方法应用免疫组化法检测73例不同级别人脑星形细胞瘤中VEGF-B、VEGF-C的表达水平和MVD。

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。
