METHODS: Surial of 22 patients who underwent pancreatectomy with R was compared with two control groups: 54 patients who underwent pancreatectomy without the need for R and 28 patients whose pre-operatie imaging suggested resectability but whose laparotomy indicated inoperability.

比较了22例进行联合血管切除重建的扩大胰腺切除患者与两个对照组的生存率：54例患者进行了没有血管重建的胰腺切除术、28例患者术前影像学显示可切除但在剖腹探查时发现不能手术切除。

Pre-operative multislice CT image evaluation is of great use for prediction of surgical removability in patients with pancreatic carcinoma pre-operatively.

术前用多层螺旋CT对胰腺癌患者进行三维血管重建，可提供可靠的肿瘤和周围血管侵犯情况的影像学资料，对胰腺癌术前可切除性评估有重要的临床意义。

In Group A,one sample was found blood current tenuity at 14 days,one was occlusive in the femoral vein at 28 days ,the blood current ran into the vena cava posterior through the branch stem.The others were normal .And in Group B,there were one sample in each phase obliterative in the femoral vein because of relapse . For scanning electron microscopy result,Group A had a process which the injury of endothelial cells were from lower-grade to repair.

结果：1。影像学检查DSA下行血管造影见C、D两组术后第7天、14天和28天股静脉血流通畅，无明显充盈缺损或闭塞，A组第14天造影1只家兔股静脉血管纤细，血流尚通畅，第28天造影见1只家兔股静脉闭塞，血流从侧枝进入后腔静脉，其余时相股静脉血流通畅无明显异常；B组第7、14、28天造影各见1只家兔股静脉闭塞，其余未见明显异常。

One of the most important problems needed to be solved rapidly is the high rate of restenosis after angioplasty.

血管成形术后较高的再狭窄率是血管介入放射学发展亟待解决的重大问题。

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。

MRTA original images, oblique sagittal and coronal reconstruction are sensitive to neurovascular compression, and able to demonstrate the relationship of the cisternal segment of trigeminal and facial nerves with the surrounding vascular structures. They provide reliable imaging evidence for etiological diagnosis of TN and HFS as well as for clinical preoperative assessment of MVD.

MRTA原始图像及斜矢状位和冠状位重建对神经血管接触敏感，能较好地显示三叉神经、面神经脑池段与周围血管之间的关系，从而为原发性TN、HFS的病因诊断及MVD术前评估提供可靠的影像学依据。

Objective: To study the relationship between emotions ,individual personality and vascular endotheliocyte function of coronary heart disease patients.

目的：研究冠心病患者情志、个性特征与血管内皮功能的关系，从血管内皮角度揭示情志、个性特征导致CHD的发病机制，为中医病因学理论提供客观依据。

Abstract］ objective to discuss radiological findings of parosteal osteosarcoma on emphasis combined with clinical pathology and literature.methods 4 cases of parosteal osteosarcoma proved by operation and pathology were analyzed retrospectively.results female was 3 cases,male was 1 case,average age was 30.5 years old,these tumors were arised on posterior border of distal femur and popliteal cavity,presented as lobular dense ossified mass,defined lesion.one case had villose margin.a thin narrow lucent zone separated the mass from the cortex at two cases.one case underwent angiography,there was no malignant feature.conclusion parosteal osteosarcoma may be divided into low-grade type and high-grade type.radiological manifestations of early stage possess character,early diagnosis conduces to establish rational treating plan and evaluate prognosis.

目的 结合临床病理学特征和文献资料，重点讨论皮质旁骨肉瘤的x线特征。方法收集经手术、病理证实的皮质旁骨肉瘤病例4例，对其进行回顾性分析。结果 4例患者女3例，男1例，平均年龄30.5岁，肿瘤均发生于股骨远端后侧和腘窝处，表现为分叶状致密骨化肿块，边界清晰，其中1例边缘呈绒毛状改变，2例有细窄透亮带与骨皮质相隔，1例行血管造影，未见血管池等恶性征象。结论皮质旁骨肉瘤分为低度恶性和高度恶性两种，早期影像学表现有特征性，早期诊断有助于制订相应的治疗方案和评估预后。

The histology of lung tissues showed that the infiltration of Eos occurred immediately after challenge, and much more accumulation of Eos in perivascular and peribronchial area at 6h, 12h, 24h and 48h following challenge. It is consistent with the changes of absolute numbers of Eos in BALF.

肺组织学检查显示抗原激发后即刻气道及血管周围即有少量Eos浸润，6h后Eos浸润明显增加，在12h时Eos浸润波及到肺实质，24h和48h时气道及血管周围Eos浸润进一步加重。

In the diagnostic process of RV , the presence of peripheral neuropathy and/or purpura/petechiae or a high weighted EAM score will increase the probability of histologically proven RV.

类风湿血管炎的诊断过程中，如出现外周神经病和紫癜/紫斑或关节外表现加权得分高，则发生组织学证实的血管炎可能性增大。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
