The typical manifestations of PHC were nodular,irregular and heterogenous enhanced regions in lesion,tumorous vessels could be seen in the arterial phase,the hyperdense regions in the arterial phases were changed to hpodense quickly in the portal phase;The characteristic findings of HCH were well-defined intense mural nodular enhancement in the arterial phase,and centripetally oriented enlargement of this nodular in the portal phase,the density of the nodular in the arterial phase were similar to that of aorta or hepatic arteries.

原发肝癌的典型表现是动脉期病灶内结节状、片状强化，并可见肿瘤血管影，强化部分在静脉期迅速呈低密度影；肝血管瘤的特征性表现为动脉期病灶边缘结节状强化，密度类似于主动脉或肝动脉，静脉期强化结节逐渐向病灶中央扩展；肝转移癌的主要表现为动、静脉期病灶边缘环状强化，中央部分无明显强化，静脉期还可见到"牛眼征"。

Methods A retrospective analysis was performed for images of CT,MRI and DSA of 12 patients with intracranial venous angiomas.In all cases,7 cases male,5 cases female,age ranged from 8 years old to 72 years old.All patients underwent the examinations of CT,MRI and/or DSA.Results All 12 patients had single lesion.In these cases,there were 6 cases （50%） located in cerebella,6 cases （50%） located in cerebra including 3 cases （25%） in lobus frontalis and 3 cases （25%） in lobus parietalis.Most patients had slight clinical symptoms and were detected the lesions accidentally when they were examined for other diseases.Compared the imaging features of CT,MRI and DSA,conventional CT scan was negative,but there were characteristic images which was "dendritic" sign in contrast-enhanced CT and MRI,and typical findings of "caput medusae"sign in venous phase of DSA.

结果 颅内静脉血管瘤均为单发；6例（50%）位於幕下小脑实质内，6例（50%）位於幕上额叶（3例25%）、顶叶（3例25%）脑实质内；患者临床症状轻微，多为合并其他病变检查时偶然发现；CT、MRI及DSA的影像比较，CT平扫为阴性，CT增强扫描与MRI平扫呈特征性表现，即树枝征，DSA静脉期可见典型表现蛇头征。

Under transthoracic echocardiography, electrode catheters positioned intracardiac and target ablation were performed with the permentnent pacemaking catheter of left subclavian vein and the ablation catheter of right femoral vein.

在经胸心脏彩超引导下，采取"多切面观察"、"导管运动中观察"，密切结合心内电生理定位，尝试左锁骨下静脉永久起搏导管和右股静脉消融导管的心内定位和靶点消融。

With 3D-doctor software, kidney, adrenal, ureter, abdominal aorta, inferior vena cava, the nephritic artery and vein, the lymph nodes beside abdominal aorta, thoracic duct, the intrailiac artery and vein, pelvis, spermaduct, prostate, the prostatic plexus, bladder, male urethra and internal obturator muscle were segmented and three-dimensional reconstructed in P4 computer. 3. With photoshop7.0 software, the major organs of the male urological and reproductive system such as ureter, bladder, urethra, prostate were segmented and the grey- color mode images through segmentation were imported to AMIRA software.

应用连续图像分割软件3D-DOCTOR，分别对肾脏、肾上腺、输尿管、腹主动脉、下腔静脉、肾动静脉、腹腔淋巴结、胸导管、主动脉旁淋巴结、髂内外动静脉、骨盆、股骨、输精管、附睾、前列腺、前列腺周围静脉丛、膀胱、男性尿道、直肠、闭孔内肌、肛提肌、尾骨肌等结构进行结构数据的分割与提取，并在PentiumⅣ计算机上完成已分割结构的三维重建。

Venipuncture when 2 M In of prolapse of nature of armrest of antebrachium edge chair, can increase pressure of vein of limbs Yuan Duanjian, make arm vein natural inside short time plentiful, after handlers take advantage of an opportunity plunges into hemostatic belt, make the same score the arm put on chair armrest, the place that hemostatic belt ties is apart from puncture to nod 10~15 Cm, time is beautiful with 30~120 S, after such making that syringe needle enters blood-vessel, continueing to advance in the process, cause loss not easily to hemal wall, raised puncture to become power and hemal repeated usage...

静脉穿刺时前臂沿椅子扶手自然下垂2 m in，可增加肢体远端浅静脉压力，使手臂静脉在短时间内自然充盈，操作者顺势扎止血带后将手臂平放于椅子扶手上，止血带扎的位置距穿刺点10~15 cm，时间以30~120 s为佳，这样使针头进入血管后在继续行进过程中，不易对血管壁造成损伤，提高了穿刺成功率和血管重复利用。。。

Results:There were 16 cases (12.5%) of the middle hepatic veins in cholecystic bed.There were 3 intruding types.

结果：肝中静脉及其属支突入胆囊床的占12.5%(16例)，突入形式主要有：①肝中静脉主干；②右前叶支、或左内叶支、或两者一起突出；③右前叶支属支、左内叶支属支、或两者一起突出3种类型。

Inferior petrosal sinus extends from the posterior part of the cavernous sinus and courses along the clivus laterally, in IPS sulcus. It usually leaves cranial cavity through the jugular foramen and eventually joins the jugular bulb or the internal jugular vein.

岩下窦起自海绵窦后端，走行在斜坡两侧的IPS沟内，通常经颈静脉孔出颅，最终汇入颈静脉球或颈内静脉，沿途接收多条静脉的注入，与颅神经Ⅵ、Ⅸ、Ⅹ、Ⅺ关系密切。

Materials and Methods: Of 62 patients with spinal AVMs which confirmed by MRI, DSA and/ or pathology, 30cases had intramedullary AVMs(13 occult AVMs, 5 glopular AVMs, and 12 juvenile AVMs), 24 cases had perimedullary AVF (5 type I , 12 type Ⅱ, and 7 type Ⅲ), and 8 cases had dural AVF.

ABSTRACT Direct intrahepatic portacaval shunt is created between the retrohepatic IVC and portal vein intrahepatically, with partial portal flow shunted directly to the IVC. DIPS can eliminate the defect that the outflow vein—hepatic vein is vulnerable to stenosis or occlusion after TIPS.

直接性门腔分流是在肝后段下腔静脉与门脉之间建立肝内分流，将部分门脉血液直接分流入粗大的下腔静脉，解决了TIPS术后分流道引流静脉——肝静脉易狭窄或闭塞的缺陷。

Following successful modeling, rats of bFGF group were intratracheally injected with 400 U bFGF and rats of VEGF group with 2 μg VEGF, once a week for three times. MSCs group was injected 1 mL suspension of 4×109/L MSCs into tail vein. MSCs+VEGF group was injected MSCs into tail vein and intratracheally injected VEGF (2 ug, three times) at the same time. Model control and normal control groups were intratracheally injected with equal volume of sodium chloride.

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
