血管充盈

The direct signs of Pulmonary embolism were luminal constriction,emphraxis,branched decreased,intraluminal low??D filling defect of blood vessel;while the indirect signs,formation of pulmonary infarction focus,pleural effusion,pneumonia,atelectasis,pulmonary dilatation and hydropericardium,etc.

肺栓塞的直接征象为管腔狭窄、阻塞、分支减少及血管腔内的低密度充盈缺损，间接征象为肺梗死灶形成、胸腔积液、肺炎、肺不张、肺动脉增宽、心包积液等。

After tying hemostasia band when patients' arms had drooped the superficial vein turgidity can be improved and accuracy of venepuncture can be increased.

采用手臂下垂法，能增加静脉充盈度，缩短扎止血带后寻找穿刺血管的时间，提高静脉穿刺成功率。

Some innate digital palmar branches could be seen at the pedicle of flyback finger flaps in which veins can be stained to black soon after infusion.It indicated that the blood circulation of arteries to capillaries to veins have completed.The radiogram of flaps showed that the overall transmittancy has been decreased and some blood vessels were visible radiologically.

指背逆行皮瓣的蒂部可见有指掌侧固有动脉的分支，灌注后可见皮瓣内静脉即刻充盈黑染，说明实验皮瓣已完成"血液"从动脉-毛细血管-静脉的循环过程，皮瓣X线造像显示整体透光度减低，皮瓣内有血管显影。

In patients with clinical evidence of hypotension associated with hypoperfusion and obvious evidence of elevated cardiac filling pressures (e.g., elevated jugular venous pressure; elevated pulmonary artery wedge pressure), intravenous inotropic or vasopressor drugs should be administered to maintain systemic perfusion and preserve end-organ performance while more definitive therapy is considered.

对伴有临床证据的因低血压而导致低灌注和有明确证据的心脏充盈压增高（如颈静脉压力增高、PCWP增高）的患者，应该应用静脉用强心剂或血管加压素维持组织灌注和靶器官功能，以进一步决定最终治疗方案。

In this article, we evaluate two characteristic CT findings: bowel configuration and mesenteric changes. The former consists of a saclike mass or cluster of dilated bowel loops.

本文中我们对两种特征性的CT表现进行评价：肠管形态和肠系膜改变，前者包括扩张肠管囊性团块或堆积，后者包括肠系膜血管蒂的充盈、伸展和移位。

Some innate digital palmar branches could be seen at the pedicle of flyback finger flaps in which veins can be stained to black soon after infusion.It indicated that the blood circulation of arteries to capillaries to veins have completed.The radiogram of flaps showed that the overall transmittancy has been decreased and some blood vessels were visible radiologically.

指背逆行皮瓣的蒂部可见有指掌侧固有动脉的分支，灌注后可见皮瓣内静脉即刻充盈黑染，说明实验皮瓣已完成&血液&从动脉-毛细血管-静脉的循环过程，皮瓣X线造像显示整体透光度减低，皮瓣内有血管显影。

Results:(1) All of HCC were irregular hyperdense in arterial phase companioned with mass and hyperdense tumor vessels.

结果 ：( 1)肝动脉期肿瘤实质出现密度高于肝实质的肿瘤血管和瘤区强化，门静脉期其密度迅速降低，至平衡期为低密度；( 2 )肿瘤边缘于肝动脉期和门静脉期均可见环行强化；( 3)转移性子灶仅在肝动脉期明显强化，门脉期全瘤密度迅速降至等密度；( 4)门静脉受累表现为肝内分支的边缘侵蚀、破坏、中断，或为不规则的充盈缺损。

Results three different CT patterns were observed,a target lesion,a reniform mass,a sausage shaped mass,with a lower attenuation centrally,representing the intussuscepted mesentery.

结果 10 例CT扫描均可见多层靶环形、肾形或香肠形软组织影，中央部为脂肪和血管轴面影。2 例淋巴瘤多处可见肿大融合的淋巴结及肠壁不规则增厚，肠腔内造影剂充盈不均，1 例术中发现肠系膜过长而引起Tret's 韧带疝。

Cast specimens of blood vessels showed that hepatic sinusoids were slightly thicker and their filling was more obvious than normal.

血管铸型标本显示肝窦略变粗，较正常更为充盈，虽有一定的变形，但仍呈放射状分布在中央静脉的周围。

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。
