And There was no serious complication;②In the course ofinterventional therapy, Direct portal vein angiography demonstrated vena coronaria ventriculi(100%)andgastricveins(65.26%)andvenagastricaposterior38.43%, Angiography demonstrated venacoronariaventriculi communicate esophagus varicose veins, gastric veins and vena gastrica posterior communicategastric varicose veins. vena coronaria ventriculi had only a small percentage of double vein, about30.57%. The sites of vena coronaria ventriculi arising from the portal vein, splenic vein, portosplenic junction, were found in 52.06%、27.39%、20.55% respectively.③12 extrahepaticprotosystemic shunts were found in these patients. Include gastro-nephrosshuntof 3 cases, 7 caseswere splenetic- nephros shunt and 2 cases shown recanalization of umbilical vein .④The averageportal pressure before and after the procedure were 3.87±1.82kPa and 3.64±1.14kPa in 73patients, but to the time of rebleeding, it was 3.96±0.23kPa in the 11 cases.⑤There werethree kinds of variceal outcome: disappearance (54,low degree (19).⑥Spearman logisticanalyse and ANOVAtest shown liver function class, variceal degree of the splenic necrosis area,the blood direction in portal vein before operation and remain small collateral routes were thesignificant factors concerning outcome of varices.⑦The bleeding volume and portalhypertensive gastropathy are main risk factors of rebleeding.⑧The course of livercirrhosis is the risk factor of survival and extrahepatic portosystemic shunt , fine varices are thebeneficial factors to survival.⑨During all cases'followed-up data, the 1, 2, 3, 4, 5 yearcumulative survival rates and rebleeding rates were 17.81%, 28.77%, 38.36%, 43.84%, 47.95%and93.15%,91.78%,86.30%,83.56%,80.82%respectively.

Our project is based on Cenozoic volcanic rocks and deep seated xenoliths in it to reconstruct the source composition and ctructure. We did field investigation, collection of samples, determination of age and composition characteristics of selected samples. The new achievements are following. 1 recognized a potassic metasomatic source of the Cenozoic volcanic rocks through an integrated research of volcanic rocks and their sources. 2 analysis of TM images suggests the Tuoyun basin is a basin with a volcano group instead of a simple volcano-tectonic basin. We found several volcanic craters and cone, and detected three such craters. 3 systematic reseach of volcanic sections and collection of samples both of volcanic rocks and xenoliths, the later includes peridotite, granulite, gneiss and variety of megacrysts. This is propitious to our further research at this rigion. We would like to point that we collected some peridotite large than 20cm in diameter. It could used to variety of analysis and end the history without mantle chemistry records in the region. 4 we got a U-Pb SHRIMP age of 3.87 Ma for the Kangxiwa basalt.It is the youngest record of U-Pb SHRIMP age in China and provide a chronology restriction for last uplifting of Tibet plateau. 5 the investigation of alkali syenite-synogranite in Taxkogan suggests that the origin of Parmir syntex is related to the Cenozoic magmatism.
