病灶

Results The average onset age of moyamoya disease was very young. Female was dominant in our studied. Younger patients with moyamoya disease mainly suffered cerebral ischemia (87.5%). Adult patients suffered more cerebral hemorrhage (41.2%). Among clinical manifestations, headache, vertigo, paralysis, hemiplegia or alternative hemiplegia were common symptoms. Sometimes aphasia, dementia, visual acuity were decreasing, epilepsy and chorea minor might occur. 14 cases had received CT examination, but none was diagnosed moyamoya disease by CT. All patients received MRI and MRA examinations were diagnosed as moyatnoya disease.

结果 烟雾病发病平均年龄较轻，女性多于男性；少儿烟雾病患者以缺血改变为主(87.5%)，成年烟雾病患者缺血改变(58.8%)与出血改变(41.2%)相当；临床以头痛、头晕、肢体无力或偏瘫或交替性瘫痪为主要表现，同时可伴失语、智能下降、视力下降、癫痫发作、小舞蹈发作等表现。14例行头CT检查仅示颅内病灶，均未提示烟雾病；25例均行MRI和MRA检查发现颅内病灶，显示颈内动脉虹吸末段和大脑前或中动脉近段狭窄或闭塞，并有脑基底部异常血管网及侧支循环形成，均被诊断为烟雾病。

The diameters of 7 cases in 21 cases were less than 3 cm.

病灶直径均小于5 cm，其中7例病灶直径小于3 cm。

Of the 12 patients with basal ganglia and/or capsular lesions, one patient had involvement of the caudate nucleus and the adjacent anterior limb of the internal capsule without any other parenchymal abnormality. In the other 11 cases, the posterior limb of the internal capsule alone (n = 4) or together with the external capsule and putamen (n = 3) or with the globus pallidus (n = 4) were affected. In all 11 of these patients, additional MDJ and/or thalamic-hypothalamic lesions were also found.

在12例基底节区和/或内囊受累的患者中，1例患者仅见尾状核及邻近的内囊前肢受累，其余部位均未见病灶；余下11例患者，内囊后肢单独受累4例；内囊后肢、壳核、外囊共同受累3例；内囊后肢同时伴苍白球受累4例；这11例患者除基底节区和/或内囊受累外，均还可见中脑-间脑结合处和/或丘脑-下丘脑区病灶。

In allthese lesions with downward extension, the red nucleus was alwaysspared. The upward extension seen with the acute lesions wascharacterized by involvement of the posterior limb of the internalcapsulae, accompanied by involvement of the globus pallidusin four and the putamen and external capsule in three.

但当病灶位于中脑-间脑结合处的偏前方时，倾向于累及皮质脊髓束；急性期向上延伸的病灶常累及内囊后肢，伴苍白球受累（4例）和壳核、外囊受累（3例）。

Most of our patients complained of a variable degee of pruritus (11/15). Nine patients had multiple flesh-colored papules distributing on the vulva. The coexistence of eyelid syringomas was found in one third of our series (5/15), and four of them also had a family history of extragenital syringomas.

在临床表现上，11位病人有不同程度的痒感，而其中有9人的病灶为多发性肤色丘疹，5位病人同时合并有其他部位的汗管瘤，其中的4位有家族成员也有汗管瘤病灶。

During ictal SPECT studies, 18 showed hyper-perfusion in solitary lobe, multi-hyper-perfusion foci in 10 patients. Compared the two examinations, 26(86.7%) were accorded with each other in 30 patients. Of the 12 patients with multiple and diffuse hypometabolism in interictal PET, 6 patients showed foci changed to solitary focal hyper-perfusion in ictal SPECT.

发作期SPECT显像18例为单叶局限性高灌注，10例为多处高灌注灶。30例患者中26例(86.7%)两项检查结果相符合，12例PET发作间期呈多病灶或弥漫性改变者，6例于发作期转化为单叶局限性病灶。

Imaging appearances of AIDS complicated with pulmoanry tuberculosis coexisted with multiple foci of infection and polymorphism that distributed in multiple lobus. Most of AIDS patients were without typical tuberculous proliferative foci and lyphadenectasis, possibly to be associated with decreasing extent of immune function and the progress of disease at various stages in the young patients observed.

AIDS合并肺结核的胸部影像学特征多表现为多性质的病灶共存，多形态、多叶段分布，以两下肺明显的渗出性、多形态病灶；纤维化、钙化、肿块样阴影少见，无典型的结核增殖灶、肺门淋巴结肿、胸水产生与有关文献报道有异，可能与本组患者为年青人及免疫下降程度和病程发展不同阶段等因素有关。

The poor prognosis of this disease entity is probably aggravated by the common misdiagnosis and delayed treatment of the lesion, therefore, an incisional biopsy should be performed in any persistent nail bed lesion to exclude the possibility of amelanotic melanoma.

因为病灶的常见错误诊断以及延迟治疗可能使不良的预后更加恶化，所以任何持续性的甲床病灶均应作切片检查以排除黑色素瘤的可能性。

For 21 cases of thyroid malignant nodule, 17 showed untidy margin and clear borderlines were detected in 4 cases; 8 cases had vesica and 9 had calcification; 6 cases showed no complete enhanced ring around the tumor, and 7 cases were revealed metastatic lymphadenopathy on the neck.

结果 47例单发良性结节中39例病变边界清晰、8例病灶边界欠清、26例囊变、10例钙化；21例恶性结节有17例病变边界不清、4例病灶边界较清、8例囊变、9例钙化、6例表现强化残圈征、9例肿瘤侵犯周围组织器官和7例颈部淋巴结转移。

The number of 5-Br deoxy uridine monophosphate and nestin in subventricle zone and dentate gyrus of rats at 3, 5, 7, 14, 21 and 30 days after MCAO were detected by immunohistochemistry and the bFGF mRNA were detected by RT-PCR at the same time.

免疫荧光法检测各组大鼠缺血再灌注损伤后第3、5、7、14、21、30天病灶侧侧脑室下区、海马齿状回区5-溴脱氧尿嘧啶核苷和Nestin的变化，逆转录聚合酶链式扩增方法检测相应时间点病灶侧碱性成纤维生长因子信使核糖核酸的表达。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
