Of course, premise has said, need the data that has existed in great quantities, unless very popular key let you occupy the first when search engine, of course, this kind of discharge is provisionality, very flabby calm, and, general very fast be occupied by a few big websites or portal net.

当然，前提说过了，需要大量已经存在的数据，除非有非常热门的要害让你占得了搜索引擎的第一位，当然，这种流量是暂时性，很不稳定，而且，一般都很快被一些大的网站或门户网占去。

Results There were slight and remarkable pulsatility in portal vein flow respecti...

结果 正常人门静脉血流频谱随呼吸周期有轻度的波动；三尖瓣返流者门静脉血流的呼吸性变化较正常人显著，且随返流程度的增加而增大，直至出现逆向血流。

The respiratory pulsatility of flows in portal vein were studied,and the pulsatility index and the correlative index between the PI and the quantity of TR were calculated.

在正常呼吸的情况下观察门静脉血流频谱的波动性，并计算血流波动系数以及波动系数与三尖瓣返流量的相关系数。

In 2001 he was asked to participate in the management of www.treddi.com a small italian CG portal ,that at the time counted up a bit more than 1000 users ;at the present it is a point of refence for all italians fascinated by computer graphics ,by January2008 it had over 30,000 registered users,In 2001,he also became aware of a small plug-in,VRay,developed by chaosgeoup ,a Bulgarian software-house .since then he has not stooped being interested in everything that has to do with the world of rendering systems ,especially VRay .

In 2001年，他被要求参与管理 www.treddi.com 一个小意大利协商小组的门户，这在当时清点了超过1000位用户；在目前它是一个点refence所有意大利迷上了计算机图形学，由January2008它已超过30000个注册用户，在2001年，他也开始意识到，一个小插件， VRay ，制定chaosgeoup ，保加利亚软件内部。从那以后他一直没有弯下腰感兴趣一切，是同世界的渲染系统，特别是VRay 。

Methods Twenty-five cases of giant PLCs, with a mean diameter of 14.78cm, were evaluated. All of the tumors involved the main hepatic veins and /or retrohepatic vena cava. Before resection the tumor was fully exposed and an occluding tape, when neccessary, was placed around the vena cava. The hepatectomies were performed under intermittent portal triad clamping.

25例累及第二第三肝门的肝癌，平均肿瘤直径14.78cm，分别压迫主要肝静脉根部或/和肝后腔静脉；进腹充分暴露肿瘤后在间歇性第一肝门阻断下切除肿瘤，切肝前根据需要预置腔静脉阻断带备用。

Methods Pregnant rats were gavaged castor oil-diet in 18 and 19 days of gestation. At the time of death, blood of portal and peripheral veins, intestinal mucosa, amnion, amniotic cells and placenta were collected, and the tissues were cultured in the presences of ricinoleic acid or indomethacin.

将妊娠18天的Wistar大鼠分实验组和对照组各8只，实验组大鼠每天两次灌服引产餐，灌服4次后剖杀大鼠，收集门静脉、末梢血，胎盘、羊膜组织及制备羊膜细胞进行体外培养。

Results The PGE2 levels in the portal vein increased, while the PGE2 levels in peripheral blood had no changes significantly, the PGE2 levels in the tissues of the intestinal mucosa, placenta, amnion and amniotic cells were increased significantly; Ricinoleic acid stimulated the synthesis of PGE2 in the above tissues invitro, which had the positive correlations with the dose of ricinoleic acid and its lasting time.

结果 实验组大鼠门静脉PGE2水平升高，外周血PGE2水平无变化；实验组大鼠肠粘膜、胎盘、羊膜组织和羊膜细胞PGE2合成明显升高；蓖麻酸刺激肠粘膜、胎盘、羊膜等组织和细胞PGE2合成，其刺激合成能力与蓖麻酸浓度及其作用时间呈正相关。

The split between the two groups can hardly be papered over.
