At the level of azygos vein, 100%of the lymph nodes of azygos vein and the superior aortic recess were located among the superior vena cava, arch of azygos vein, trachea and concavity of aortic arch.

主动脉弓和奇静脉弓在同一横平面占20.00%±7.30%，40.00%±8.94%的奇静脉弓在主动脉弓凹面平面；②80.00%±7.30%的主动脉上隐窝上界位于主动脉弓右前端头臂干起始处；③在主动脉弓平面，腔静脉后淋巴结位于主动脉弓、上腔静脉和气管之间，出现率为100%；④在奇静脉弓平面，奇静脉弓淋巴结和主动脉上隐窝位于上腔静脉、奇静脉弓、气管和主动脉凹面所围成的气管前间隙内。

This condition is called azygous continuation of the inferior vena cava

这种情况叫azygous continuation of the inferior vena cava（我的理解是腔静脉肝段缺如而与奇静脉吻合，经上腔静脉从右上方注入共同心房）。

This condition is called azygous continuation of the inferior ena caa

这种情况叫 azygous continuation of the inferior ena caa （我的理解是腔静脉肝段缺如而与奇静脉吻合，经上腔静脉从右上方注入共同心房）。

The mono directional Glenn operation ( n =7) was performed by side to side anastomosis of superior vena cavae with right pulmonary artery with a beating heart supported by cardiopulmonary bypass.

3例双向 Glenn手术，上腔静脉与右肺动脉进行端侧吻合，上腔静脉近心端予以缝闭。手术结果，单向 Glenn手术患者，术后动脉血氧饱和度由术前的 5 0 %～ 6 0 %提高至术后的 70 %～ 80 %。

The ex perimental results indicate that the rats of the experimental group all manifested with postnecrotic cirrho sis, mainly forming pseudolobules, the third stage lesions; deep lingual venous pressure elevated which was correlated with that of portal pressure, portal blood flow decreased predominantly, as compare...

认为肝硬变门脉高压性瘀证的舌脉粗张与细络瘀血主要是因门脉血经门—腔侧支循环回流入上腔静脉，引起上腔静脉阻力增大，压力增高，导致舌的静脉系统回流受阻，舌深静脉压力升高所致。

When a sudden power failure or accident or normal pump stops when the pump stops, the valve inlet water velocity to reduce stress Agency, the valve plate also fall, when its velocity is zero (that is, inlet flow rate is zero Department), large valve plate because of its own gravity and rapidly turn off (time 3s ~ 5s), the majority of water to prevent backflow, when the valve before and after the formation of a water pressure, water stress, on the one hand through the small valve at the bottom of the three slot for pressure relief vent pressure. 4 water stress from the bypass tube into the cavity patch up the control room (this process for the suction pressure chamber that can effectively absorb the energy of water), when water stress on cavity than inferior vena cava, the pressure of water promote the diaphragm down mobile , the current cavity pressure of water being squeezed out all the small valve plate slowly drop back to standby status, the process time to ease closure adjustable (3s ~ 150s), then the valve has been fully closed, watertight.

当突然停电或事故停泵或正常停泵时，阀门进水口处压力水流速降低，大阀板也随之下降，当其流速为零时，大阀板由于自身重力而迅速关闭（时间3s～5s），可防止大部分水倒流，此时阀门前后形成一种水压差，压力水一方面通过小阀板底部的三条泄压槽进行泄压。4）压力水从旁通管进入膜片控制室上腔（此过程为吸压腔，能有效吸收一部分水能量），当上腔压力水大于下腔时，压力水推动膜片往下移动，当下腔压力水全部被挤出来时，小阀板缓缓下降，恢复到待机状态，此过程中缓闭时间可调节（3s～150s），届时阀板已全部关闭，滴水不漏。

The cut-off valve with pilot valve without hand wheel, stem and lift nut inside will guide block and guide slot Butterfly Valves to guide sleeve, the disc-shaped disc to disc type bowl shape, and holes in the bottom of the flap valve to open, the valve cover of the original valve stem hole to hole diversion, because of increased pressure ring, ring, and the valve flap to class mortar, so that the flow passage separated the upper chamber cavity, external cavity, cavity, in the cavity and The external cavity increases with draft tube and stainless steel manual ball valve, flap valve in the cover plate and the center of the end of installing the spring, the upper flap valve install compression seal of the pressure ring, outside the cavity of the wall to open a Drainage holes.
