Results: In 6 patients the relationship of Broccas area and precentral motor area to the frontal lobe tumor was identified allowing pre-operative neurosurgical planning to minimize language and motor disruption. Diffusion tensor images were corrupted by motion in one patient but successfully demonstrate the impact of tumor on white matter tracts in 5 patients. Fractional anisotropy images, showed disruption of the left arcuate fasciculus in one patient, deviation/deformation in 2 cases and unaffected by tumor in the remaining two cases.

因刺激任务为按键反应模式，5例肿瘤患者双侧均可见初级运动皮质(M1)和辅助运动区的激活，1例因右侧肢体瘫痪而只显示右侧M1的激活。1例患者在DTI扫描过程中头动明显而失败，5例肿瘤患者FA图显示良好，纤维束重建后1例可见弓状束的浸润破坏，2例伴有弓状束变形及移位，2例弓状束未见破坏或移位。

Their feature on histology not is apparently, well differentiated liposarcoma with well fattiness tumor as well as dedifferentiated liposarcoma with malignant shuttle shape / much shape do not break up tumor distinguish is still a baffling problem.

它们在组织学士特征不是很明显，高分化与良性脂肪性肿瘤以及去分化与恶性梭形／多形未分化肿瘤的鉴别仍是一个难题。

Parthenolide is extract from feverfew, it's main component is sesquiterpene, it is commanly used in west country and is mainly used to therapy skin infection, rheumatic disorder, migraine. But recent research indicate that parthenolide can regulate many pathway of signal in the cell, inhibit the cyclooxygenase, TNF-α, interleukin-1 expression induced by lipopolysaccharide in macrophage, inhibit the iNOS expression in human monocyt, inhibit the activity of NF-κB in Hela cell, inhibit the growth of tumor cell and can relieve the myocardial ischemical reperfusion injury and so on. But the invention research about the effection of parthenolide on the VSMC is very rare in the world, so we do some research about the effection of inhibition of parthenpolide on the proliferation of VSMC and the signal transduction mechanism.

小白菊内酯(parthenolide，又名Sesquiterpene lactone)是艾叶菊属黑叶母菊的提取物，主要成分是倍半萜烯内酯，西方国家较为常用，主要用于治疗皮肤感染、风湿病和偏头痛，但近年来发现小白菊内酯能调控细胞内多种信号途径，如抑制巨噬细胞中脂多糖诱导的Cox，肿瘤坏死因子α和白细胞介素-1的表达，能抑制人单核细胞中iNOS的表达，能抑制Hela细胞中NF-κB的活性，抑制肿瘤细胞的生长，同时能减轻心肌缺血再灌注损伤等，但小白菊内酯在VSMC中的干预研究目前国内外非常罕见，为了确切评价小白菊内酯对血管平滑肌细胞增殖的抑制作用及相关的信号转导机制，我们进行了一些研究。

Methods From January 1998, sixteen patients suffed from osteosarcoma(6 cases), chondrosarcoma(3 cases), gaint cell tumor(6 cases) and fibrosarcoma(1 case) arising from femur(5 cases), tibia(5 cases), humerus(3 cases), fibula(2 cases), radius(1 case).

1998年1月起，我院对16例肢体恶性骨肿瘤（按病理骨肉瘤6例，软骨肉瘤3例，骨巨细胞瘤6例，纤维肉瘤1例；按部位股骨5例，胫骨5例，肱骨3例，腓骨2例，桡骨1例）行骨肿瘤局部切除术及术中放疗加植骨。

Two kinds of tumor models, C57BL/6 mice bearing B16 melanoma and BALB/c mice bearing S180 fibrosarcoma were successfully established in the left leg of mice by subdermal injection of tumor cells.

在B16肿瘤模型中，小鼠左后肢皮下接种2×10〓/鼠B16细胞，于接种后第2、15、25天肿瘤局部注射NDV2×10〓PFU，同时设荷瘤对照组。

This study attempted to further characterize CD4+CD25+ forkhead/winged helix transcription factor (FoxP3)+ Treg in blood, tumor, and nontumor lier tissues of HCC patients, and to understand how the Treg affects immune responses and contributes to disease progression.

本研究拟进一步揭示叉状头/翼状螺旋转录因子（FoxP3）阳性的Treg（FoxP3+Treg）在血液、肿瘤和HCC患者非肿瘤肝组织中的表达特征，并了解Treg如何影响免疫反应和对HCC病程的影响。
