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. Conclusion The interventional disconnection treatment for liver cirrhosis and portalhypertension was designed suitability. It rapidlycontrol bleeding,butpressure of portal vein was notobvious high, perfusion was not low .it was compared with surgery therapeutic that interventionaldisconnection treatment was safe and had a significant clinical effect to hemorrhage and preventfrom rebleeding.

Acanthosis nigricans has received attention as a type 2 diabetes sign, but Dr. Bennett noted that this dermatologic condition may simply indicate increased insulin resistance. He emphasized that children with type 1 diabetes do have symptoms, while those with type 2 usually do not. Hispanic children, African-American children, and those of Polynesian heritage also seem more vulnerable to developing type 2 diabetes than white children, although obesity and being female clearly increase the risk in all ethnic groups, he said. Currently, there is no direct evidence that physical inactivity, separate from its effect on body mass index, is a risk factor for type 2 diabetes in youngsters.

黑色棘皮病因为是第二型糖尿病的一项病徵而受到瞩目，但Bennett医师表示，这种皮肤疾病可能仅代表胰岛素抗性增加；他强调，这在第一型糖尿病的孩童身上会有此症状，第二型糖尿病则否；他指出，虽然肥胖者与女性在所有种族中有明显地第二型糖尿病增加风险，但西班牙、非裔美国籍以及波里尼西亚人孩童比白人孩童更容易发生；目前没有直接证据证明，来自於缺乏运动对身体质量指数的影响，是造成年轻人发生第二型糖尿病的危险因子。
