胸部计算机断层扫描及软式支气管镜检发现在气管下段有多姿性肿瘤。 - clinical value of multiple tumor markers protein biochip detective system for malignant tumor
多种肿瘤标志物蛋白芯片检测系统对恶性肿瘤的临床应用价值 - scientists have shown in animal models that they can produce multiple tumors, but they are still not certain if the viruses can have the same effects in humans
研究人员已经用动物模型证明，它们可以导致多种肿瘤，但不能明确这些病毒是否对人也有同样致瘤作用。 - at present, in an attempt to stimulate specific antitumor immunity, experimental models and clinical studies are currently evaluating the potent antigen-presenting capacity of dc combined with single or multiple tumor antigen epitopes . however, there are several problems in utilizing pulsing dc with synthetic immunodominant peptides from identified antigens . 1 ) the potential induction of tolerance; 2 ) the need to determine the patient's hla haplotype, the limitation of therapy to patients whose tumors express defined specific tumor antigens in the context of the correct hla phenotype, the unavailability of peptides for all hla haplotypes; 3 ) the lack of cd4 help cell-related epitopes for most antigens; and 4 ) the ctl resulting from such protocols have a good in vitro capacity to kill peptide-pulsed target cells but only a modest capacity to kill tumor cells
但是，学者们发现这一疗法存在着如下的缺陷：单一ctl表位抗原肽的应用其抗肿瘤作用弱于多种肿瘤抗原的联合应用，且有诱导免疫耐受的潜在危险，有时反而会促进肿瘤的生长；事先需对患者的hla单倍型进行鉴定，以确定ctl表位与hla单倍型是否匹配，目前尚缺乏能与所有hla单倍型相匹配的ctl表位，从而限制了这一疗法的应用；这一疗法所产生的ctl在体外能有效杀伤经肿瘤抗原肽共孵育过的靶细胞，但对肿瘤细胞的杀伤能力较弱：这种l表位抗原肽缺乏cd4汀h细胞相关的表位，因此，不能诱导有效的th细胞免疫应答。 - It's difficult to find multiple tumor in a sentence. 用multiple tumor造句挺难的
