病灶

Uniting fMRI and DTI to analyze the mechanism and prognosis of cerebral motor function injury and rehabilitationObjective:Analyzing the relation between motor dysfunction and fiber bundle injury; investigating the injury and rehabilitation mechanism of hemiparalysis extremity\'s motor path.

根据试验一和试验二的纳入标准纳入7例受试者，进行DTI成像扫描，使用BrainVoyager软件和SPSS13.0统计软件包进行图像和数据分析，进行fMRI、DTI以及病灶的三维重建与图像融合。

Results:There is no obvious difference m FA values of uninjured internal capsule of cerebrum between case group and normal group;the normal group FA values is obviously better than case group;the FA values in hemiparalysis patient\'s impairment encephalic region is much lower than the uninjured side;please refer to the text for the results of fMRI,DTI and focus of disease three-dimensional reconstruction and image fusion.

偏瘫患者病损脑区与健侧脑区相比FA值显著降低。(2)fMRI、DTI以及病灶的三维重建与图像融合结果请参见正文图示。

All hereditary RB are bilateral, or multifocal, 15% of unilateral RB is hereditable and 85% of unilateral RB is non hereditable.

所有遗传性的RB的发病都是累及双眼或多病灶的，15%的单眼发病的RB是遗传性的和85%的单眼发病RB则不是遗传性的。

In treatment group, 42 cases received 50 Gy radiation, at 2 Gy per day, 5 d per week in the upper mediastinum, hilus of lung, below the primary focus first and then underwent X-knife for the primary focuses, and other 14 recurrent and metastatic cases received irradiation of 8-12 Gy per day, 5 d by X-knife alone.

治疗组中42例为外照射上纵隔、同侧肺门、隆突下及原发灶50 Gy/25F后加用X线刀治疗原发灶5 Gy/次×5次；14例为肺转移癌或手术后外周孤立性复发病灶行单纯立体定向放射治疗，8～12 Gy/次×5次。

In conclusion, Kikuchi-Fujimoto disease can masquerade as a single, rapidlygrowing, parotid tumor in a middle-aged man. Because it is histiocytic necrotizing lymphadenitis adjoining the parotid gland, Kikuchi-Fujimoto disease should be considered a cause of parotid tumor.

经此案例可知，菊池－藤本氏病可以单一、快速增大，发生在中年男性且以疑似腮腺肿瘤为表徵，实际上是邻近腮腺的组织发生了组织球性坏死性淋巴结炎，故临床上耳下附近的疑似腮腺肿瘤病灶，应将本病列入鉴别诊断。

The morphology and characteristics of enhancement were studied, and compared with histopathologic and angiographic findings.

结果：74％的肝细胞癌在动脉期呈高密度，76％在门静脉期呈低密度。10例门静脉期等密度的病灶在动脉期均呈高密度。

The canceration of adenomas was found in 3 out of 14 benign adenomas in 2 out of the 4 cases (50%) of homochronous multiple carcinoma.

2腺瘤癌变的诊断标准：①同一病灶中，原来比较正常的腺管被覆上皮被癌细胞取代。

Results High dense renal cyst is usually homogeneous hypoechogenicity on sonograms and homogeneous high/iso attenuation on CT images and color doppler is helpful in diagnosing.Atypical angiomyolipoma usually shows homogeneous high attenuation on unenhanced CT images,homogeneous enhancement on enhanced CT and homogeneous isoechogenicity on sonograms.The CT features of Xanthogranulomatous pyelonephritisinclude multiple,rounded,low density areas with enhancing rings arranged in a hydronephrotic pattern known as bear paw sign.Acute focal bacterial nephritisshows wedge lesion and stripe sign on delayed enhanced CT images.

结果 高密度肾囊肿常表现为B超均匀低回声，CT均质或高密度灶，彩色多普勒超声有助诊断；不典型肾血管肌脂瘤常表现为B超均匀回声，CT平扫均质高密度且均匀强化；黄色肉芽肿性肾盂肾炎的特征是CT示群集的类圆形的低密度区以及环形增强带形成&熊掌征&；急性局限性细菌性肾炎的CT延时增强扫描以及动态观察显示楔形病灶以及条纹征，并随治疗逐渐消退。

Classically, the skin lesions occur perinatally in four successive stages: inflammatory vesicular (stage 1), verrucous (stage 2), hyperpigmented (stage 3), and scarring (stage 4), along the lines of Blaschko, reflecting the somatic mosaicism of X-chromosome inactivation in female patients.

典型的皮肤表现发生在周产期并可区分为四个阶段：发炎水泡，疣状增生，色素沉著和疤痕形成，而这些病灶都沿著Blaschko's line分布。它代表了女性患者身上一种嵌合型X染色体异常的现象。

Histopathology of the hyperpigmented lesion revealed increase of melanin in the basal layer, pigment incontinence and amorphous eosinophilic masses stained positive as with Congo red in the papillary dermis.

色素沉著的病灶其组织病理显示在基底层有黑色素的增加，乳突状真皮出现色素失调和均质的嗜伊红性块状物质沉积，且以刚果红染色呈阳性反应。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
