查询词典 malignant tumor

That PI and the percentage of the cells in s-phase of the borderline/malignant and heteroploid/aneuploid tumors were higher ted to higher mortality and relapse rate as well as the corresponding risk. Because of the changable characters and dissociative phenomenon of the tumor, the measurement of PI and the percentage of cells in s-phase may be disturbed in few of diploid tumor and in part of double DNA stem ones. Therefore other paramet- ers should be added to analyse before making any conclu- sion.

交界性和恶性、异倍体或非整倍体肿瘤的PI和S期细胞百分率较高，病死加复发率和相对危险性增加；由于肿瘤的异质性和"分离现象"，对于少数2倍体肿瘤和部分双DNA干系肿瘤PI和S期细胞百分率的测定易受干扰，故应结合其它参数综合分析。

Compared with classical cytotoxic T lymphocytes , NK cells are superior in the following aspects: NK cells are among the first cell types to be activated after intracellular pathogen stimuli, the activity of NK cells peaked between 1 to 3 days, retained during the first 7-10 days, and the T cells response emerged only after 7 days when the NK cell responses begin to decline; though comprising of only 10％-15％ of peripheral lymphocytes, NK cells mobilize most of the cell populations in a strong and high level response to different invasions, and act as key factors at early defense before a specific immune response could mount, while only certain clones were involved in T cell response; NK cells kill virus-infected or malignant transformed cells without pre-sensitization and without restriction by major histocompatibility antigen, which is usually a mechanism of immune escape to T cell recognition by virus-infected or tumor cells, thus NK cell in complementary with T cells play crucial roles in tumor and virus eradication.

NK细胞以其强大的细胞毒活性为特征，与细胞毒性T细胞相比，NK细胞具有如下特点：NK细胞虽然只占外周血淋巴细胞的10-15％，但是对刺激性因素产生应答的过程十分迅速，一次可以调动大多数细胞共同参与，而不是几个克隆的活化，免疫应答的强度高；病毒感染或恶性转化细胞的一个主要特征是细胞表达的MHCⅠ类分子下降或消失，并借助这一机制逃避特异性T细胞应答的识别，NK细胞介导的杀伤活性无需抗原刺激，不受MHCⅠ分子表达的限制，从而与T细胞应答互为补充发挥免疫防御的功能；NK细胞的免疫活性可以被多种细胞因子上调，其中IFNα，IL-2，IL-12，IL-15和IL-18具备更强的作用；NK细胞具有强大的细胞因子分泌功能，对于启动T细胞特异性应答必不可少。

It was also showed that Moxibustion and the combined treatment could not only promote the immune functions of tumor-bearing organism, but also exsert its influence on the biological characteristics of tumor cells, which gave a new scientific explanation to the traditional Chinese medicine theory of "supporting the energy of life to expell the evil factors" in the treatment of malignant tumors.

本工作的结果表明，进行针灸抗肿瘤的疗效和机理研究，不仅要考虑其对机体免疫功能的良性调整作用，同时还要着眼于其对肿瘤细胞生物学特性的影响，这样才能更全面地评估针灸的抗肿瘤作用及其机理。

To regulate tumor cells proliferation and metastasis. In many malignant tumors, CD44 has shed by MT1-MMP extracellularly, and causes the release of the soluble CD44, which facilitate the tumor cells motility.

在多种恶性肿瘤中，CD44分子胞外结构域可被膜结合型基质金属蛋白酶1(MT1-MMP)剪切，导致&可溶性&CD44分子的释放，此过程在细胞迁移中发挥重要作用。

About 48%(90/194) were below 29 years of age. Ninety-nine of 194 cases had either radiotherapy alone or supplementary treatment with radiotherapy following surgery. We analyzed multiple prognostic factors. The factors of importance included postoperative radiotherapy; female in glioblastoma multiforme; the primary tumor dose above 5000 rads and/or whole brain irradiation in malignant astrocytoma and glioblastoma multiforme; the primary tumor dose above 4500 rads in ependymoma, medulloblastoma and oligodendroglioma; and spinal axis irradiation above 2000 rads in ependymoma and medulloblastoma that produced a better prognosis than in other groups.

男与女之比例为2.7比1，年龄分布自1至81岁，平均年龄33.3±19.3岁，中值年龄为34岁，29岁以下占48%(90/194)，其中99例单独或手术后辅以放射腺治疗，分析同种脑瘤的预后因素，其中多形神经胶母细胞瘤有手术后放射线治疗或女性，多形神经胶母细胞瘤合并星细胞瘤原发肿瘤剂量5000雷得以上或曾全颅腔照射，神经管胚细胞瘤，间胶质母细胞瘤，及室管膜瘤原发肿瘤剂量4500雷得以上，室管膜瘤及神经管胚细胞瘤有脊轴照射2000雷得以上预后均佳，且统计上有显著的差异。

Results In 9 cases of endometrial biopsy of materials by uterine curettage, the cells of endometrial stromal sarcomas of 6 cases were well differentiated and like stromal cells of endometrial hyperplasia; the cells of endometrial stromal sarcomas of 3 cases were poor differentiated, the cells of 2 were like that of malignant lymphoma, and another like that of pleomorphous sarcoma. In 9 cases were found the distribution of vessels cluster like endometrial corkscrew small artery. The tumor cells were grew along lymphatic or protruded in lymphatic, and there were small islands or small pieces of tumor cells in the interspace of muscles in 2 cases. The contrastive observation of the specimens of resected uterines of 9 cases confirmed the valve of above features to the confessed diagnosis of endometrial stromal sarcomas in the materials of endometrial biopsy or uterine curettage.
