断流

There are two systems in the portal system, namely, gastrosplenic GS system and portomesenteric system, and between the two systems there is a functional barrier. DSRS + SPD + Disconnection operation can strengthen this barrier.

Up to May 2000, before water delivering, the cutting off runoff of lower Tarim River had been continued for 30 years, all the surface water had disappeared for a long time. It forces the environment which is originally controlled by dry circulation to develop rapidly toward dry environment. The desertification had expanded greatly. As the results, a large number of the saline meadow and halophilous shrub deserta had disappeared.

：由于近30a的断流，使本来就处于干旱环境中的塔里木河下游末端朝着更加干旱的方向急剧发展，致使原有的荒漠植被大量消失，植物成片死亡，或濒于死亡，并形成大片裸地；遗留种类极度贫乏，群落结构简单，一年生草本植物趋于灭绝。

Based on the detailed water quality monitoring data of about 317 hydrometric stations from 1960 to 2000 and water quantity data of 20 hydrometric stations between 1919 and 2000 included in the Hydrological Yearbooks, which were all published by Yellow River Conservancy Commission, and socio-economic data related to the Yellow River, the characteristics of water quantity, major ion chemistry, organic contamination and their mechanisms, and integrated watershed management issues of the Yellow River have been systematically studied in this work.

本文在全面分析黄河流域300余水文站过去40年（1960—2000）水质资料和干支流20余水文站过去近50年（1950—2000）径流量资料的基础上，研究了：（1）、黄河水量的基本特征和近40年来的变化，重点讨论了黄河下游&断流&现象的发展及原因：（2）、黄河天然水质的基本特征、区域分布和影响因素；（3）、黄河天然水质40年来的变化趋势及原因；（4）、黄河水系氮污染和有机污染的特征、近40年来的发展，及其与社会经济发展的关系；（5）、黄河下游水质变化与水量变化的关系；以及，（6）、黄河水质水量管理中的制度安排问题。

Because there is not enough water for the Yellow River in recent years, finding a proper water allocation solution for the different irrigation regions is becoming an impendent problem.

东营市共有六大农业灌区，由于黄河经常发生断流，且每年的来水量不断减少，因此对各个灌区进行合理配水是一个急待解决的问题。

Results Among 6 cases with PCTPV, 4 cases revealed occlusion of the main branch of portal vein at the hepatic hilum, 2 cases revealed occlusion of the common portal vein, and a masslike network of tortuous veins around the hepatic hilum and many small irregular veins radiating from the network to the liver were demonstrated.

结果：6例中4例清楚显示门脉主要分支近肝门处阻塞，2例门静脉主干阻塞，代之以肿块样纡曲血管并在其周围形成向肝性放射状侧支血管影像，以及离肝性侧支循环静脉。6例CT血管成像均能对与分流或断流手术有关的血管解剖提供准确信息。

This seems to be the path taken by most Americans, who have grown numbly indifferent to the incessant stream of disappointment over the continued failure of Congress to truly represent the will of the people.

Methods Control the methanol feeding in growth phase of Hansenula polymorpha by online monitoring. In induction phase, the expression levels of HBsAg when the methanol feeding were controlled by DO-Stat/pH-Stat method and by offline gas chromatography, as well as those when only methanol was fed and glycerol and methanol were fed alternatively, were compared.

在细胞生长阶段采用DO/pH线测量的控制方法，使酵母细胞密度达到一个较高水平，诱导期比较DO-Stat/pH-Stat法和离线检测甲醇两种控制流加甲醇的方法，同时也比较用甘油和甲醇双碳源间断流加法与单纯流加甲醇法对目的蛋白表达的影响。

This operation is suitable for the following portal hypertension: simple occlusion of hepatic vein (a pathological type of Budd-Chiari syndrome)thrombosis in portal vein or prehepatic portal hypertension due to cavernous transformation; intrahepatic portal hypertension with rebleeding after treatment of splenectomy or without operation, and the patients with liver function in Child A or B class.

本手术主要适应于以下原因引起的门静脉高压：①单纯化肝静脉闭塞(布-加综合征的一种病理类型)；②门静脉主干血栓形成成海绵样变性引起的肝前性门静脉高压；③肝内型门静脉高压行断流术后再发出血或未行手术，肝功能为Child A和B级者。

In PHT group,the preoperation liver function levels were A level in 14 cases,B level in 28 cases.
