18F-FDG is taken up by cells phosphorylated by hexokinase (whose mitochondrial form is greatly elevated in rapidly-growing malignant tumours) and retained by tissues with high metabolic activity such as most types of malignant tumours.

在被细胞摄取之后，18F-FDG将由己糖激酶（在快速生长型恶性肿瘤之中，线粒体型己糖激酶显著升高）加以磷酸化，并为代谢活跃的组织所滞留，如大多数类型的恶性肿瘤。

There was no significant difference in MGMT expression between invasive and noninvasive tumours, or between recurrent and nonrecurrent tumours.

然而，侵袭性与非侵袭性肿瘤间或复发与未复发肿瘤间，MGMT的表达水平并没有明显差异。

The major advantage of CTA is simple,rapid,noninvasive and reliable.It is very useful for evaluation of cerebrovascular diseases,intracranial hypervascular tumours and skull base tumours,especially sensitive in detection of intracranial aneurysms.

CTA具有简单、快速、无创和可靠等优点，适合于脑血管病、血供丰富的颅内肿瘤及颅底肿瘤的术前诊断和评估，对颅内动脉瘤的诊断具有极高的准确性。

There were positive correlation between eIF4E and cyclin D〓 in head and neck tumours, eIF4E overexpression could improve cyclin D〓 translation and expression in malignant tumours to maladjust cell cycle and induce canceration.

提示了在恶性肿瘤发生发展中eIF4E可以通过调控cyclin D〓的表达来影响细胞周期活动，使正常的细胞增殖周期失调，细胞进程变得不可逆，从而导致了恶性肿瘤的发生。

Secondary brain tumours are more common, only about 10% of brain tumours actually start in the brain.

继发性脑肿瘤是较为常见的，只有约10 ％的脑肿瘤，其实开始在大脑中。

Results:The positive expression of P53 and c－Myc protein in nuclei was bound up with poor-differentiated tumours;the positive expression of Fas and c－Myc protein in cytoplasms was consistent with well-differentiated tumours.

采用免疫组织化学方法对骨肉瘤、骨化性纤维瘤、骨纤维结构不良和正常骨痂组织进行c－Myc、Fas和P53蛋白测定，与肿瘤组织学分级、细胞分化及核丝分裂比较分析。

Results: 5 protuberances from outside organ (aorta, n=2; spleen, n=1; gallblader, n=1; left hepatic lobe, n=1) and 82 SMTs were detected by mEUS including 45 leiomyomas (esophageal, n=38; gastric. N=7), 17 benign strornal tumours. 6 malignent stromal tumours in stomach. 4 Jipomas (esophageal, n=1; gastric, n=3), 3 varices in gastric fundus. 4 etopic pacreaces in stomach 3 cysts in duodenum. 19 leiomyomas derived from muscularis mucosa, 4 lipomas and 3 cysts derived from suhmucosa were resected by endoscopic snare cauterization. 3 varices in fundus were treated by nylon ligation. 5 malignent stromal tumours were resected surgically. Of which 30 were identified by pathology except 1 malignent stromal tumour was misdiagnosed as leiomyoma by EUS.

结果：mEUS检查的87例患者中，发现消化道壁外压迫5例（其中主动脉弓2例，脾脏1例，胆囊及肝左叶各1例）；粘膜下肿瘤82例，包括平滑肌瘤45例，良性间质瘤17例，恶性间质瘤6例，脂肪瘤4例，静脉瘤3例，异位胰腺4例，囊肿3例。19例起源于粘膜肌层的平滑肌瘤行高频电切除术切除，3例静脉瘤行尼龙圈套结扎，4例脂肪瘤及3例囊肿行高频电切除。5例恶性间质瘤行手术治疗。1例平滑肌瘤，切除后病理诊断为恶性间质瘤，其余的病理诊断与超声诊断相符。

Tris-(1-aziridinyl)- phosphine oxide and 2-[bis-(2-chloroethyl)-amino]-tetrahydro-1, 3, 2-oxazaphospholidine-2-oxide(Ⅲ, B-518) possess inhibitory action against a variety of animal tumours and have been used clinically. Recently, bis-(1-aziridinyl)-phosphinyl carbamic acid ethyl ester(Ⅱ, AB-100) was found to possess significant activity with low toxicity on experimental animal tumours.

双(2-氯乙基)氨基磷酰二氯与乙烯亚胺在脱水苯或对氧六环中并在三乙胺的存在下进行缩合，生成N，N-双(2-氯乙基)-N′，N-二乙烯基-磷酰胺；与双巯基或双氨基化合物作用，则生成相应的环状磷酰胺、磷酰胺酯以及磷酰胺硫代酯氮芥类化合物。
