Results showed that the expressions of both Fas and FasL on tumor cells were up-regulated compared with noncancerous liver cells from same patient.When compared with the PBLs from same patient,the expression of Fas on TILs was highly up-regulated whereas the FasL down-regulated.

结果显示，肝细胞癌患者肿瘤细胞Fas与FasL表达水平较自身非肿瘤肝细胞上调；肿瘤浸润淋巴细胞与自身外周血淋巴细胞相比，Fas表达上调而FasL表达下调。

Materials and Methods: A 47-year-old woman complained of a right posterior thigh mass that she had discovered two months earlier. Serial examinations showed a large neurogenic tumor about 4.8 cm in maximal diameter originating from the right sciatic nerve. Intraoperatively, we found the tumor encapsulated by the stretching nerve fibers. It was feasible to peel off these fibers from the tumor; therefore, we removed the tumor without severing the sciatic nerve.

材料及方法：一个四十七岁的妇女，最近两个多月抱怨右大腿后侧有一肿块，相关的检查疑似为神经源起之肿瘤，最大直径为4.8公分，术中发现肿瘤本身被撑开的坐骨神经束包覆住，而肿瘤可在小心剥开这些神经束后被移除掉，坐骨神经可被完全的保留而不需要牺牲。

Previous studies showed that exosome could serve as a tumor therapeutic alternative and tumor vaccine, which could induce protective immunity against syngeneic and allogeneic tumor cells.

研究说明，EXOSOME可以作为肿瘤治疗的制剂和肿瘤疫苗，介导针对同系小鼠和不同系小鼠的肿瘤免疫保护作用。

So it may be necessary to block the overexpression of the VEGF in tumor cells with ribozyme technique,thus to prevent the cells from over proliferation,and search for a new treatment of the ovarian cancer.

因此，采用核酶技术阻断卵巢肿瘤细胞中VEGF的过量表达，有可能阻止肿瘤细胞的增殖，为卵巢肿瘤的治疗开创一条新途径。

Objective to search for the courses of the middle soft tissue tumor treated recurs, the article discussed the factors of recur, and the radiotherapy influences.methods the review analysised process of diagnosis and the recurs situation of 16 cases with middle soft tissue tumor.results 15 patients received routine widespread excision methods and added partial radiotherapy, all of them were no recured after 3 years followde-up visit.

中山大学附属第五医院肿瘤放疗科，广东珠海 519000；4。中山大学附属第五医院普外科，广东珠海 519000 目的探讨中间型软组织肿瘤术后复发的因素，放射治疗对其复发的影响。方法回顾性分析16例中间型软组织肿瘤诊治过程及复发情况。

In conclusion, our research has indicated that amine oximes or other hypoxia imaging agents might not be structure-specific pharmaceuticals, and lipophilicity seemed to be an important factor in design for hypoxia agents.

由于〓Tc〓-〓在胃肠道等脏器分布较多，难以检测腹腔肿瘤，但可广泛适用于其它部位实体瘤的诊断。而上述三者更集中于肝、肾，可能适用于某些胃肠道肿瘤和妇科肿瘤的乏氧显像。

Objective:To study the radiation-induced changes of carcinoma lesion and non-tumor tissues and organs of pelvis in patients with cervical canner on magnetic resonance imaging during and after radiation therapy. Methods:pelvic MR imaging was performed in 36 patients with cervical carcinoma before, during, and after radiation therapy. The size and signal changes of carcinoma lesions and pelvic soft tissues were observed on MR images.

目的：分析宫颈癌放射治疗中与放疗后肿瘤与盆腔非肿瘤软组织的MRI改变方法：36例经病理证实的宫颈癌患者在放射治疗、中、和治疗后不同时间阶段行盆腔的MRI成像，并观察肿瘤及盆腔软组织器官在放疗前后的小或信号改变。

Result: With a high cancer-inhibiting rate on the animal model having been transplanted the cancer, this medicine can remarkably restrain the growth of cancer cells cultivated in vitro and improve the life quality of mouse model, and also shows obvious promotion and enhancement function on the DTH ear-swelling of mouse with cancer, the proliferation of mouse spleen lymphocyte induced by ConA and the cytokine (TNF-α、IFN-γ) of mouse with cancer respectively. It can obviously decrease the adverse effects like weight reduction, damage of viscera and degradation of life quality caused by the chemotherapeutic medicines, and has a remarkable stimulation on the lymphocyte proliferation induced by ConA. It is also able to improve the ratio of SMMC-7721 cells in G0-G1 period and reduce the cell amount in G2/M period to cut down the possibility of stepping into the division period; additionally, it can obviously inhibit some cancer genes of the cancer cells and meanwhile up regulate the cancer-inhibiting gene.

结果：本品能明显抑制体外培养肿瘤细胞的生长，对在体肿瘤移植模型动物具有较高的抑瘤率，能明显提高模型小鼠的生存质量；对荷瘤小鼠DTH耳肿胀、ConA诱导的小鼠脾淋巴细胞增殖、荷瘤小鼠细胞因子（TNF-α、IFN-γ）呈现明显的促进或提高作用；能显著减少化疗药所引起的小鼠体重降低、脏器损害以及生存质量下降等不良作用；本品含药血清对ConA诱导的淋巴细胞增殖具有明显的促进作用；能提高SMMC-7721细胞G0-G1期比例，降低G2/M期细胞数目，而减少其进入分裂期；对肿瘤细胞的多个癌基因具有明显的抑制作用，同时上调抑癌基因等。

Interception of lyphatic drainage by Nd:YAG laser irradiation in rat urinary bladder ［J］.Lasers Surg Med,1984;4（2）:167-172.［10］Shanghai Neoplasm Hospital.

我们的实验结果提示，在普通手术或CO2 激光手术切割肿瘤之前，可结合使用Nd-YAG激光，先用Nd-YAG激光做肿瘤周边小范围的封闭照射，就可大大减少肿瘤转移的机会。

Measurement of blood concentration of indocyanine green by pulse dye densitometry—Comparison with the conventional spectrophotometric method.

肝脏的实质性肿瘤富有结构和功能上非正常的血管网[12]，这将导致肿瘤组织内的血流动力学改变；据此推想，这可能是肝脏实质性肿瘤相对于正常肝组织清除ICG较慢的原因[13，14]。
