上海交通大学医学院附属第三人民医院肿瘤放疗科，上海 201900［摘要］背景与目的：精确地勾画鼻咽癌肿瘤靶区是制定最佳治疗计划、降低肿瘤的局部复发率和保护周围正常重要器官的首要条件。

The microwave scattered signal of breast tumor is simulated by using our FDTD codes and poles of the scatted signal of breast tumor are subsequently extracted by using Pronys method.

本文首先详细介绍了奇点展开法的背景及其原理，接着应用我们开发的时域有限差分仿真程序得到早期乳房肿瘤的微波散射信号，采用Prony极点提取方法对肿瘤的微波散射信号进行肿瘤特征极点的提取。

Mature teratomas of benign tumors, and said, skin samples cyst is one of the most common ovarian tumor, ovarian tumors by 10%— 20%, germ cell tumors of 85%— 97%, 95% teratomas.

成熟畸胎瘤属良性肿瘤，又称皮样囊肿，是最常见的卵巢肿瘤，占卵巢肿瘤10%～20%，占生殖细胞肿瘤85%～97%，占畸胎瘤95%以上。

This investigation was to establish a simplified culture system to isolate and passage brain tumor stem cells from human medulloblastoma, observe their proliferation and differentiation, and determine the expression of normal neural stem cell antigens, CD133 and Nestin, in BTSCs. METHODS: Eleven specimens of medulloblastoma were acutely dissociated and triturated into single cells without trypsin digestion.

本研究旨在利用简化的无血清培养基和悬浮培养方法，从人髓母细胞瘤中分离培养脑肿瘤干细胞，观察其在体外的增殖、分化，鉴定其特异性标志物CD133和Nestin的表达，验证肿瘤组织切片中CD133阳性细胞的存在，为脑肿瘤干细胞的进一步研究打下基础。

The transplantation of VX2 tumor in Newzealand rabbit lung were established by two methods, and some characters of these two animal model were assessed; VX2tumors in Newzealand rabbit lung were ablated with anchor-shaped electrodes radiofrquency technique, and the course of pathological changes and CT scanning changes were observed, the relationship between them was assessed as well, a forward study of evaluating cell apoptosis status in the ablated area was conducted too.

本实验采用两种方法在新西兰白兔肺内建立VX2肿瘤移植模型；采用锚状电极技术对新西兰白兔肺内的VX2肿瘤进行RFA治疗，观察其病理改变及CT表现的变化；进一步观察了RFA治疗后消融灶不同区域的肿瘤细胞凋亡情况。

2Radiofrequency ablation with anchor-shaped electrodes could induce coagulation necrosis of most of the VX2 nodules in rabbit lung, and could induce apoptosis of tumor cells; The course of pathological changes of ablated area was surrounded by organization, the ablated area would be encapsulated by fibrosis tissue.

2采用锚状电极RFA治疗兔肺内VX2肿瘤，其基本病理改变为：绝大多数肿瘤病灶的凝固性坏死，进一步的改变为凝固性坏死区被机化包裹，可有钙盐沉积；RFA可诱导肿瘤细胞凋亡。

The infiltrating MC around the cancer tissue may play a important role in the angiogenesis of tumor and the proliferation of tumor cell by releasing biological active substance. MCD、MVD and PCNA might be effective targets for the tumor progression, metastatic status and judging prognosis of the cervical carcinoma.

癌组织中浸润的MC通过释放生物活性物质促进肿瘤血管的形成和肿瘤细胞增殖，MCD、MVD和PCNA的异常表达与宫颈癌的发生、发展密切相关，对评估肿瘤恶性程度、转移和预后具有重要的意义。

Radiological imaging studies suggested unresectable tumors in 10 patients (50%) because of multiple bilobar liver metastases in six patients, superior mesenteric vein invasion in three patients, and extensive nodal metastases in one patients. Tumors were completely resected in 15 patients (75%).

放射影像的研究建议10名患者的肿瘤是无法切除的（50%），因为六名患者为多重的双叶肝脏转移，三个患者的肿瘤转移至中肠，而一为患者有广大的节癌症转移，另外，15名患者（75%）的肿瘤被完全地重新切除。

But the overseas MMP-1-associated cases of oral cancer lacked those of Taiwan, where there are many betel nut chewers. Therefore, this research aimed at Taiwan, to analyze the MMP-1 expression of oral cancer in the just- mentioned patients.

共选取了奇美医学中心口腔颚面外科 30 位只具有长期嚼食槟榔并接受口腔癌手术切除的患者，分别进行肿瘤样本组织与肿瘤周围组织中 MMP-1 的半定量反转录作用-聚合酶连锁反应，发现在肿瘤样本组织中 MMP-1 mRNA 有普遍提高的表现。
