瘤形

They were 36% and 8% in medulloblastomas, and 28% and 8% in anaplastic oligodendrogliomas, and 24% and 4% in anaplastic ependymomas.

两组患者生存时间差异有统计学意义(P.05)。结论 EGFR的过表达和PTEN的缺失在多形性胶质母细胞瘤中常见，并和预后关系密切。

Anaplastic tumors has obvious pleomorphic, the tumor cells to each other in size and shape have a lot of variation, which often can not determine the source of their organization.

间变性肿瘤具有明显的多形性，瘤细胞彼此在大小和形状上有很大的变异，因此往往不能确定其组织来源。

Pleomorphic adenoma is the most common gland tumor of parotid origin, accounting for 60 to 70%. This kind of tumor usually presents as a slow-growing painless mass anteroinferior to the ear. The diagnosis is based on physical examination, image studying and even fine needle aspiration biopsy. The optimal method of treatment of such tumors is local excision or paroidectomy in which the entire capsule is totally dissected off but the facial nerve is spared. Diagnosis and treatment planning are focused on preventing tumor recurrence and consequent malignant transformation.

腮腺之多形性腺瘤乃是唾液腺最常见的肿瘤，约占所有唾液腺良性肿瘤的百分之六十至七十，这类的肿瘤在临床上的表现常是耳下缓慢增生的无痛性肿块，临床上诊断的依据必须配合临床检查、电脑断层扫描、磁振造影及细针抽取切片的病理检查方可得知，其治疗方式主要是对肿瘤进行局部切除手术或腮腺的切除手术，手术中颜面神经需小心保留，但须将肿瘤的外膜部分切除乾净，诊断及治疗计画著重在预防肿瘤复发及肿瘤产生恶性转变。

Leaf sheaths densely pilose or with caducous tubercle-based hairs; leaf blades linear-lanceolate, 10–60 × 0.5–2 cm, tapering to base and apex, softly pubescent; ligule 1–2 mm, glabrous or ciliolate.

叶鞘密被柔毛或具早落的基于小瘤的毛；叶片线形披针形 10-60 * 0.5-2 厘米，渐狭至基部和先端，软的短柔毛；叶舌1-2毫米，无毛或者具短缘毛。

Results The splenic infraction was showed triangular or unr egular low density regions which had no enhancement,Metastasis tumor of spleen had imaged cystiform low density single or several masses,The patho logicai presented little nodular or circle enhancement.Primary lymphoma of spleen had presented part range low density regions and uneven enhancement .

结果 脾梗塞呈三角形或不规则形低密度区，病变无强化；脾转移瘤为囊状低密度肿块，单发或多发，病灶呈小结节状或环形强化；脾原发恶性淋巴瘤，呈局灶性低密度区和不均匀强化。

Seeds 1 to numerous, reniform, ovoid, or rarely dorsiventrally compressed, abaxially grooved, blunt, or sharply pointed, rarely fimbriate-pectinate; testa granular, striate or tuberculate, rarely smooth or spongy; embryo strongly curved and surrounding perisperm or straight but eccentric; perisperm mealy.

种子1 至多数，肾形，卵球形，或者很少背腹扁平，背面有槽，钝，或者明显尖，很少流苏状栉状；种皮颗粒状，具条纹或者具瘤，很少光滑或者海绵状胚显著弯曲，围绕外胚乳或者直而偏心；外胚乳粉状。

Results Most of 37 cases located at junctional zone between ectocinerea and alba of cerebrum. Shapes of SBM are multiple, such as node, ring form and cyst-solid node were commonly seen. Most of these were accompanied with marked hydropsia. The degree of hydropsia was related with the site of lesion. Different degree enhancement was showed on enhanced CT in all cases.

结果 单发脑转移瘤病灶多位于大脑灰白质交界区；形态多样，可表现为结节、环形及囊实性不规则形，以结节多见，多伴有明显水肿，水肿程度与解剖部位有关；增强扫描可见不同程度均匀或不均匀强化。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
