成纤维细胞瘤

Objective: To observe the effects of Cinnamyl aldehyde on NIH3T3 cell cycle and explore the possible mechanism further.

中文摘要：目的：观察肉桂主要成分桂皮醛对小鼠成纤维瘤细胞株NIH3T3细胞周期及相关蛋白的影响。

To study the characteristics of the mesenchymal cells of ameloblastic fibrosarcoma, three cases of AFS were studied immunohistochemically and ultrastructurally.

为探讨成釉细胞纤维肉瘤间叶细胞的本质及特征，作者采用免疫组化和电镜技术，对3例AFS间叶细胞进行了研究，并与6例成釉细胞纤维瘤进行比较。

Recombinant apoE〓 protein could inhibit the death of the neurocyte cell of mice brain induced by beta amyloidal peptide 25-35 fragment and the death of the SK-N-SH-neuroblastoma cell induced by beta amyloidal peptide 25-35 fragment and 1-40 fragment.

重组apoE〓蛋白对Aβ 25—35多肽诱导的胎鼠大脑皮质神经细胞凋亡及Aβ25-35和A β1-40多肽诱导的神经成纤维胶质瘤细胞生存力下降均具有明显的拮抗作用，表明apoE对神经退化性疾病中的细胞死亡具有拮抗作用。

Most endothelial cells fell off, elastic fibre autolyze; the number of SMC decreased, some SMC nucleus contracted completely or depressed, typical apoptosis body were seen in later stage, muscle silk autolyzed and disappeared mostly; in outer layer saw much collagenic fiber, arranged unorderly; inflammation cells were seen in the aneurysm wall(hypertrophy cell et al.).

多数瘤壁的内皮细胞溶解脱落，不连续，弹力纤维自溶；动脉瘤血管壁均可见SMC明显减少，较多SMC染色质边聚、固缩，部分SMC核全部固缩或出现不规则凹陷，SMC核胞浆或胞核部分出现脱落或裂解成碎片，晚期可见典型的凋亡小体出现，肌丝大都自溶消失：外膜可见大量的胶原纤维，排列较紊乱；瘤壁还可见炎性细胞浸润。

Results Microscopically, the tumor cells were epithelioid or short spindled and special nests of tumor cells separated by arboring fibrovascular septa. Such morphological variants of CCSK as myxoid degeneration, microcysts formation and sclerosing pattern of extracellular hyalined collagen simulating osteoid were present in some regions.

结果 镜下见瘤细胞为上皮样或短梭形，被分枝状纤维血管间质分隔成巢团状，部分区域见黏液样变性微囊肿和细胞外胶原玻璃样变类似骨样组织的硬化型等形态变异。

We describe a case of NLPHL showing a variant histologic pattern characterized by small and large clusters of lymphocyte predominance cells within nodules defined by follicular dendritic cell meshworks, associated with numerous neutrophils and areas of internodular fibrosis. Focally, the neoplastic cells had lacunar cell-like cytologic features.

在此，我们描述一例组织形态特殊的NLPHL，其形态学表现为以淋巴细胞为主的细胞排列成大小不等的结节，结节均由滤泡树突状细胞网网罗，结节内见中性粒细胞浸润，部分结节间见纤维化，局灶瘤细胞呈陷窝样。

The tumors ranged from 5.5 to 20 cm and had a characteristic histologic appearance with irregular, sharply circumscribed nests and islands of bland-appearing spindled to focally epithelioid cells, surrounded by a cellular desmoplastic stroma.

这9例肿瘤大小为5.5至20cm，瘤组织特征性地表现为：温和的梭形细胞至灶性上皮样细胞排列成巢或成岛，这些细胞巢团界限相当清楚但不规则，周围间质细胞丰富、促纤维组织增生性。

Objective To investigate the clinical usefulness of DTI multiple parameter and diffusion tenser tracting in astrocytomas.

目的 探讨磁共振扩散张量成像多参数综合分析及扩散张量纤维束成像在星形细胞瘤临床分级中的应用价值。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
