在静脉中的

All the lesions in 10 patients did not show the ＂caput medusae＂ sign in arterial phase of IVM.

结论多排螺旋CT在诊断IVM中，脑静脉期血管成像优于动脉期，而静脉系统与病灶容积重建、图像的融合，是显示IVM的有效重建方法。

Results Along with the formation of liver cirrhosis and PHG, the gastric mucosa became thicker and more congestive. The portal pressure elevated gradually, followed by the decrease of endothelin-1 levels in both the peripheral and the portal blood. ETA mRNA expression was significantly elevated in the postcapillary venule and the precapillary arteriole, and predominantly in the latter.

结果：Wistar大鼠在肝硬化门静脉高压形成过程中，其胃黏膜厚度增加，黏膜淤血；门静脉压力呈梯度性升高；外周及门静脉血浆ET水平随门静脉压力升高而降低；胃黏膜ETA mRNA主要在黏膜基底部的微循环前微动脉和后微静脉血管壁表达，其表达水平随ET浓度的降低和门静脉压力的升高而增加，且其在小动脉表达明显强于小静脉。

In the case of our patient, we believe that the piece of cerclage wire entered the venous circulation around the knee and then migrated through the caval system to reach the right ventricle.

在我们这里病例中，我们认为环扎钢丝片断进入了膝关节周围的静脉回流，并通过腔静脉系统而到达右心室。

The rupture of the branches of venae hepaticae intermediae intruding beds of gallbladders is the important reason causing the bleeding on beds of gallbladders during cholecystectomize.

结论（1）突入胆囊床的肝中静脉属支破裂是引起胆囊切除时胆囊床大出血的重要原因；（2）在胆囊床由左前下向右后上方缝合肝组织是对突入胆囊床肝中静脉属支破裂出血的有效预防方法。

"A combination of D-dimer and calf circumference provides an easy and effective means of excluding DVT in patients suspected of having proximal DVT," the authors write."A combination of D-dimer less than 0.5 ng/mL and calf circumference of 2 cm or less reliably excludes DVT in the acute setting and allows for use of DU in a nonemergent setting. Patients with a positive D-dimer or calf circumference of more than 2 cm require emergent DU to exclude DVT."

同时检验D-dimer与小腿的肿胀情形，能让我们简单有效地在疑似罹患近端深部静脉血栓患者中先行过滤；若D-dimer小於0.5 ng/mL，同时小腿肿胀达2公分，仍无法分辨者，可尝试安排都卜勒超音波检查来做诊断确认；一旦D-dimer 呈阳性反应，或小腿肿胀超过2公分以上者，便需要进行紧急的都卜勒超音波检查，才能确认诊断是否罹患深部静脉血栓。

In recent years,human umbilical vein endothelial cells have highly application value in gestational hypertension and phlebothrombosis research.

近年来，人脐静脉内皮细胞在妊娠高血压综合征、静脉血栓等方面的研究中有很高的应用价值。

Methods Fifteen cadaveric heads were taken in this study. The arteries and veins of the heads were perfused with red and blue latex, respectively, for simulating pterion approach under microscope. The spatial relationship between the anterior segment of basal vein and the operation space was examined. The cranium was then removed, the basal vein and its branches were observed and measured in the free brain.

取15具（30侧）尸头标本，动、静脉分别用红、蓝色乳胶灌注，在显微镜下模拟翼点手术入路，分别从手术中常用的间隙进行操作，观察基底静脉前段与手术间隙的关系。

There were 15 pediatric ALL patients, which had received 50 times of chemotherapy with HD-MTX. The records about blood concentration of MTX and clinical conditions for 50 times chemotherapy were divided into two groups. Group I: contained 25 records of stand-risk patients, administering MTX 3.0g/m2; Group II: contained 25 records of mid and high-risk patients, administering 5.0g/m2. Continuous intravenous dripped MTX for 24th in both two groups, while implemented hydrating and alkalizing for 4 days. All patients were rescued 6 times through leucovorin, 15mg/m~2, since 12th after the end of MTX dripping. Then examined the blood concentration of MTX by fluorescence polarization immunoassay approach at 24h, 44h, 68h, at the same time inspected liver function, blood routine examination, the occurrence time and degree of toxicological reactions.

观察15例ALL住院患儿，接受大剂量MTX共50例次，按ALL危险度分2组，低危治疗组接受MTX剂量为3.0g/m2为I组；中高危治疗组接受MTX剂量为5.0g/m2为II组，连续静脉点滴MTX共24小时，同时给予水化碱化治疗，共4天，全部病例均在MTX滴注结束后12小时开始静脉推注四氢叶酸钙(leucovorin，LV)解救，15mg/m2/次，共6次，采用免疫偏振荧光法检测药物滴注24、44、68小时MTX血药浓度，同时检测两组病例的肝功、血常规，观察临床出现MTX毒副反应的时间及程度，观察每个病例毒副反应出现程度与MTX血药浓度关系，两组毒副反应程度比较，进行统计学分析。

The 4th left rib was cut and a model of left coronary artery occlusion/release was carried outo Rats were divided randomly into 4 groups: control group without LCA occlusion (group A, n=6);I/R group(group B, n=6); ketamine(5mg.kg-1)+I/R group (group C, n=6); ketamine(10mg.kg-1)+I/R group(group D,n=6)o All rats in groups B, C , D were subjected to 30 minutes of LCA occlusion followed by 120minutes of reperfusion. Rats in group C and D were injected with 5mg.kg-1 and 10mg.kg-1 of ketamine before reperfusion, respectively. Significant electrocardiogram and color changes at the area at risk were considered indicative of successful coronary occlusion and reperfusionc Serum was exampled from left jugular vein at 30 minutes and 120 minutes during reperfusion to measure IL-6 and TNF- level by ELISA measurements. After reperfusion of 120 minutes, the heart was removed and the cardiac apex was exampled with snap-frozen in liquid nitrogen and stored at -70 C .
