查询词典 venous

The marked and consistent mixed venous desaturation during early mobilization has not been described before and the clinical consequences and underlying mechanism require further investigation.

既往没有关於早期活动后发生显著和持续的混合静脉血氧饱和度下降的描述。其临床结果和基本机制有待进一步研究。

At the mesencephalic, diencephalic, and pontine levels, thrombosis of small veins might be accompanied by a very large, sometimes hemorrhagic lesion, since there is nearly no collateral venous pathway.

但在间脑、中脑、脑桥水平，由于几乎没有静脉侧支循环通路存在，因此一旦这些部位的小静脉受累形成血栓，就会产生较大的、甚至有时伴出血的病灶。

In NBS, lesions therefore appear secondary to the small vessel vasculitis, and the anatomy of those intraaxial venous structures explains the dominant involvement of the upper brain stem and diencephalic structures.

神经白塞病患者的病灶系小血管炎所致，因此，脑内静脉结构的解剖学特点可以解释神经白塞病常易累及脑干上部和间脑结构。

With the development of lesion inautonomic nervous system, i.e. the elevation of baroreflex set point, blood pressureincreases to stage 1 hypertension and worsens. Furthermore, the role of the effectors,including PVR, ventricular end-systolic elastance, venous unstressed volumes and heartrate, in the regulation of hypertension was analyzed. The results exhibit that the ANSregulation on hypertension works mainly by the reduction of PVR and the increase ofvenous unstressed volume.

随着自主神经系统损坏程度的不断加重，即工作调定点进一步升高，血压水平上升到了1级高血压并趋于严重；研究了神经调节的各效应器(外周血管阻力、心肌最大弹性度、心率和静脉非压力容积)对高血压的作用，表明神经调节机制对高血压的调节主要是通过降低外周血管阻力和增加静脉非压力容积实现的。

Embryologically, the abnormality most likely develops at gestational weeks four to eight. It is hypothesized that impaired venous outflow, caused by loss of normal connections between cortical veins and dural and calvarial circulation, results in persistent, primitive vascular plexus.

胚胎学上，发育异常最可能发生在孕期的第4-8周，其发病机制被认为是静脉流出受损，这是由于皮层静脉与硬膜及颅盖静脉循环之间的正常连接出现障碍，导致原始血管持续存在。

Endovenous laser treatment to promote venous occlusion［J］.

腔内激光治疗大隐静脉曲张的疗效评价［J］。

Radiofrequence endovenous closure symdrome for treating venous ulceration in lower limb is better than traditional operation method.

射频静脉腔内闭合系统射频封闭治疗手术方法较传统方法效果更好。

Days.Conclusion Radiofrequence endovenous closure symdrome for treating venous ulceration in lower limb is better than traditional operation method.

射频静脉腔内闭合系统射频封闭治疗手术方法较传统方法效果更好。

70 cases were randomly divided into two group: epidural PCA and venous PCA.

70例食管癌患者随机分为两组：硬膜外自控组和静脉自控组。

Indeed, by increasing the pressure in the right atrium and in the left ventricle with respect to extrathoracic vascular beds, positive-pressure ventilation affects the pressure gradients for both systemic venous return and left-ventricular ejection increase; Fig.

实际上，机械正压通气引起的右心房、左心室内的压力增加，这样和胸腔外血管床形成一定的压力梯度，此压力梯度会影响心肺两系统的静脉回流及左心射血（增加，见图1）。

You can do some assertiveness training.

你可以进行一些自信训练。

We were well on the path to making a rear-wheel-drive global platform," says Mays."

我们正致力于建立一个后轮驱动的平台，"Mays这样说道。"
