压迫

This head CT scan demonstrates a mass with irregular margins in the region of the sella. Such a mass may impinge upon the optic chiasm, just like a pituitary adenoma.

头颅CT显示颅咽管瘤，在蝶鞍可见边缘不规则的大肿块，象垂体腺瘤一样压迫视交叉。

Nonfunctioning adenomas are discovered incidentally or present with mass effect such as bitemporal hemianopsia with compression of the optic chiasm, headache with hydrocephalus, hypopituitarism, and cranial nerve palsies secondary to invasion of the cavernous sinus.

无功能性的垂体腺瘤偶尔发现，或者出现肿瘤占位效应所致的临床症状，如压迫视交叉所致双颞侧偏盲，脑积水所致的头痛，垂体功能减退，以及海绵窦受侵所致的颅神经病。

Methods Two hundred and seven patients with newly diagnosed and treated benign sellar region mass lesions that were touching or compressing the optic chiasma and/or optic tract were Included. The mass lesions included 116 cases of pituitary adenoma 52 cases of craniopharyngioma, 18 cases of meningioma, 14 cases of cystic lession and 7 cases of pituitary abscess. The MR features, positive ratio, relationship of OTE sign to tumor size or pre-operative visual signs were retrospectively analyzed.

207例初次确诊和手术病理证实的鞍区良性占位病变患者，肿瘤均接触或压迫视交叉和/或视束，其中垂体腺瘤116例、颅咽管瘤52例、鞍区脑膜瘤18例、囊肿性病变14例、垂体脓肿7例，回顾性分析MR上OTE征的影像学特点、阳性率、与肿瘤大小和术前视觉功能障碍的关系。

Results Among 38 cases of pituitary macroadenomas which had ivaded the surrounding tissue,5 cases showed the tumor growing upward simply and oppressing the optic chiasma,20 cases growing upward mainly and involving the sphenoid sadele,13 cases involving one or both sides of the sphenoid sadele mainly and ivading up or／and down.

结果：5例肿瘤单纯向鞍上生长压迫视交叉，20例以向上生长为主并有鞍旁受累，13例以向一侧或两侧鞍旁生长为主并向上或向下侵犯。

He renounced his claim to the chieftainship because he didn't want to oppress the people as a ruler. In 1944,he joined the African National Congress, known as ANC, a black-liberation group ,and in 1949 he became one of its leaders , helping to revitalize the organization and opposing the apartheid policies South Africa's official system of segregation and discrimination against the country's nonwhite majority. In 1960, after the police shot more than 200 unarmed black protesters at Sharpeville and the government banned the ANC, Mandela abandoned his nonviolent stance and began to advocate acts of sabotage.

他因为不愿意做一个压迫人民的统治者而放弃了酋长的继承权。1944年，他加入了非洲国民大会，也称"非国大"，一个解放黑人的组织，并在1949年成为该组织的一名领导，帮助重新振兴这个组织和反对种族隔离政策--南非对占这个国家人口绝大多数的非白色人种的隔离和歧视的官方制度。1960年，警方在沙佩维尔射杀了200多名手无寸铁的黑人抗议者，同时政府取缔了非国大。

Light and electron microscopy showed central chromatolysis of motor neurons in the lumbar cord from 1 week after the start of compression.

研究结果：光学和电子显微镜检查表明从压迫1周后出现腰髓运动神经元的中心染色质溶解。3周后，在前角可见到一些神经元的凋亡。

Howeer, few studies hae looked at changes of neurons within the caused by disturbance of axonal flow, the axon reaction, chromatolysis, and cell death as a result of mechanical compression of the entral

但是， 很少有研究关注腹侧神经根机械性压迫所致的神经元改变，如轴流，轴索反应，染色质溶解，细胞死亡等。

Pathological study revealed compression mainly caused neuron atrophy and anterior column damage in the white matter, on the other hand, excessive cervical flexion combined with compression resulted in neuron atrophy, neuron edema, chromatolysis、vacuolization and it also caused demyelination、axon degeneration、axon necrosis in all the columns of the white matter.

病理结果显示，单纯压迫时，神经元的变化以萎缩为主，白质损害主要在前索。而在过度屈曲活动组，神经元除萎缩外，肿胀、尼氏体溶解和空泡变性等病理变化也比较常见，白质各索均可有损害。
