EChT can promote tumor necrosis and induce apoptosis so as to control the growth of tumor itself. EChT is also believed to prolonged living time of the rats and strengthened immunity.

电化学治疗促进肿瘤坏死，诱发肿瘤细胞凋亡，可明显抑制肿瘤生长，改善和纠正机体免疫紊乱，增强大鼠免疫力，延长大鼠生存期。

Methods The nude mice tumors were formed by injection of human ovarian cancer cell line AO and AO/HSV1-tkc (AO cells carried with HSV1-tk gene which was constructed in China) subcutaneously, and then were transplanted to the omentum of nude mice. The filter-passing culture fluid of VPC/HSV1-tkc was injected daily into the peritoneum of the nude mice in the group of in vivo. Finally, all of the three groups of nude mice accepted the treatment of GCV.

先将人卵巢癌细胞AO及携有HSV1-tk基因的AO细胞（AO/HSV1-tkc）注射于裸鼠皮下，形成肿瘤后再移植于裸鼠网膜，并以病毒生产细胞（VPC/HSV1-tkc）的培养液对AO网膜移植瘤进行体内转染，然后以GCV对体外AO/HSV1-tkc转移的肿瘤及经体内转染的AO肿瘤进行治疗。

In contrast to 5-Fu, the antitumor activities were studied in vitro with SGC-7901, LoVo and Hela, and in vivo with mice transplanted tumors of Heps, S180 and EC Heps, S180 and EC. The pharmacologic experiments were done by various doses of PPH.

以氟脲嘧啶(5-Fu)为对照，体外肿瘤细胞株选择SGC-7901人胃癌、LoVo人结肠腺癌和Hela人宫颈癌；体内移植性肿瘤细胞株选择肝癌实体型、肉瘤(S180)、艾氏癌实体，用不同剂量的PPH进行抗肿瘤药效实验。

With knowing more and more tumor immunity theory and new experiment technology, tumor vaccines has become one of the most attractive methods to prevent and cure tumor.

随着对肿瘤免疫理论的深入认识和一些新的实验方法的涌现，肿瘤疫苗已成为预防和治疗肿瘤转移、复发的有力手段。

When existing a relatively large juxta-pleural nodule in lung CT image,because of the lacunas in the segmented lung,the attached nodules may not be distinguishable from the lung.

在计算机辅助CT图像肺部肿瘤诊断系统中，当肺区内部存在较大粘连肿瘤时，将导致分割出来的肺区存在较大的缺陷，因而在肺区内部就无法识别粘连肿瘤。

CD4+CD25+ regulatory T cells(CD4+CD25+ Tregs) can suppress the useful immune response against tumors, which lead to immune tolerance to tumors in tumor patients.

CD4+CD25+调节性T细胞(CD4+CD25+ regulatory T cells， CD4+CD25+ Tregs)可抑制机体对肿瘤的免疫应答，导致不利于肿瘤患者的对肿瘤的免疫耐受。

Often women with small tumors undergo lumpectomy to have the tumor removed.

通常，患有乳腺小肿瘤的女性接受乳房肿瘤切除术以去除肿瘤。

The effect of antisene GA gene on the biological characteristics of colon cancer cell line DH52 was evaluated by MTT and electron m...

结论GA反义基因可抑制肿瘤细胞内GA基因的表达，使细胞内GA活性下降，并导致肿瘤细胞利用Gln障碍，最终使肿瘤细胞生长受抑制。

Severe deficiency of the vitamin may impair cell-mediated-immunity and stimulate tumor growth by activating gene transcription, while megadose of B6 could improve the celluar-imunity against development of neoplasms.

近年来人们发现B_6除具有上述作用外，尚具有抑制肿瘤生长的作用，机体如果缺乏B_6除可造成细胞免疫力下降外，还能通过激活转录作用促进肿瘤增殖；故当补充B_6时则可改善机体的细胞免疫功能，对抗肿瘤的发生和发展。

The size, layer of origin, border of CISMTs can be distinguished clearly by mEUS, leading to definite diagnosis of SMT. EUS is important in the choice of therapy for SMTs and shoud routinely he performed on all suspected SMTs prior to attempt at removel.

mEUS检查能清楚显示上消化道黏膜下肿瘤的大小，起源层次、生长方向及邻近组织结构关系，较准确地判断肿瘤的性质，进而指导黏膜下肿瘤治疗方案的选择。
