The section thickness was 5mm,the best section was selected before injection of nonionic contrast material, hen nonionic contrast material l.5m1/kg were injected via the antecubital vein in the rate of 2ml/sec, two serial scannings were obtained began at 6s and 2mm, for the first series the scanning internal was 3 seconds, for the second series, the scanning internal was 7 seconds.3 Methods of studying figureThe CT numbers of lesion on plain CT and on contrasted CT at serial phases were recorded, on which the time-intensity was produced.

计算出不同时相时的CT增强值，绘出动态增强曲线。在不知道病变病理结果的情况下，由三位有经验的医师在不知道病理结果的情况下记录上述病例的动态增强模式及其动态变化。 4。增强峰值与肺血供来源和血管密度的关系的评价其中32例准备手术的SPN，术前行CT同层动态增强扫描后测量增强后第一次循环肺动脉期与主动脉期CT值。然后分别与平扫时CT值比较；术后对瘤体CT测量兴趣区取材并行HE染色，随机取5次，在放大40倍的显微镜下观察5mm范围内直径0.02～0.1mm和＞0.1mm的微血管数目，5次的平均值颀士学泣衫艾中文赂要即为兴趣区对应的血管数目，井将其与瘤体增强峰值作相关性分析。

Over a 14-year period, 95 patients were operated on transcranially with the following conditions: congenital anomalies (Apert's syndrome, Crouzon's disease, simple craniosynostosis, orbital hypertelorism), tumors (fibrous dysplasia, neurofibromatosis, sareoma, carcinoma) and trauma (primary or secondary reconstructions).

在14年间，我们共有95位病人曾接受经颅颅颜手术，包含下列病症：先天性畸形有Apert氏症候群，Crouzon氏病，单纯颅缝线封闭过早，眼过距症；肿瘤有纤维性发育不良，神经纤维瘤病，肉瘤，癌瘤；及外伤性首次或后续重建。

Objective: To evaluate the inhibitory effect of intraperitoneal sustained-release chemotherapy with 5-FU on the growth of H22 ascitic tumor in mice.

目的：观察5-氟尿嘧啶(5-FU)腹腔内缓释化疗对H22腹水瘤小鼠的抑瘤作用。

In this work, smears of ascitic fluid of mice 5—6 days after inoculation of Ehrlich carcinoma were stained by means of Feulgen reaction.

上述资料足以说明本药对Ehrlich腹水瘤的抑制作用，主要是由于它直接影响瘤细胞分裂繁殖的结果。

The apoptosis rates of H22 ascitic cells were analyzed with flow cytometry 9 and 12 days after injection of H22 cells and the proliferation index was calculated.

观察各组小鼠的生存期；流式细胞仪测定腹腔注射后第9、12天各组小鼠腹水瘤细胞的凋亡率，计算增殖指数；腹腔注射后第12天电镜观察各组腹水瘤细胞涂片。

Cerebral injury is a serious complication in the operation of AAA. For patient with atheromatous disease, additional methods to prevent perioperative embolic stroke are needed.

中枢神经系统的损害是主动脉弓瘤手术治疗的严重并发症，对粥样硬化所致的主动脉弓瘤，需采取更进一步的措施防止脑栓塞的发生。

In addition, ABA had a significantly inhibiting effects on the proliferation of tumor subcutaneous-injected in athymic mice.

此外，ABA对裸鼠皮下移植瘤有明显的抑瘤作用。

Most endothelial cells fell off, elastic fibre autolyze; the number of SMC decreased, some SMC nucleus contracted completely or depressed, typical apoptosis body were seen in later stage, muscle silk autolyzed and disappeared mostly; in outer layer saw much collagenic fiber, arranged unorderly; inflammation cells were seen in the aneurysm wall(hypertrophy cell et al.).

多数瘤壁的内皮细胞溶解脱落，不连续，弹力纤维自溶；动脉瘤血管壁均可见SMC明显减少，较多SMC染色质边聚、固缩，部分SMC核全部固缩或出现不规则凹陷，SMC核胞浆或胞核部分出现脱落或裂解成碎片，晚期可见典型的凋亡小体出现，肌丝大都自溶消失：外膜可见大量的胶原纤维，排列较紊乱；瘤壁还可见炎性细胞浸润。

The expression of nodD is subject to negative autoregulation.

体外实验结果表明，HurL蛋白在适当的浓度下，可刺激主要的结瘤调控基因nodD的体外转录，揭示其可能参与结瘤基因表达的调控。

It also indicates that the expression of WT1 is regulated strictly in time and space, and the aberrant expression of WT1 may result in retarded differentiation of blastemal cell leading NR or nephroblastoma.

提示在散发性肾母细胞瘤发生中除WT1突变外，WT1表达延迟可能是其中起重要作用的机制之一；WT1基因与肾母细胞瘤的组织分化有关，可能诱导胚基细胞向上皮细胞方向分化。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
