主要是記述在我學我的身體時得到的一些拉七拉雜的資料,不過我想可能不是對我自己有用而已,所以有一些我會多多少少地改成中文化。all the news may be the important informations so i would translate to short notes here. [2010.05.29]

Beta blockers alone more effective for first variceal bleeding, study finds

ScienceDaily (2010-06-09) -- A controlled trial conducted by researchers in Taiwan suggests that a combination of band ligation and nadolol may not be the most effective prophylaxis for first variceal bleeding resulting from cirrhosis.
在預防因[肝硬化]而導致的[首次靜脈曲張出血],採結合band ligation與nadolol二種方法可能不是最有效的。
如標題,單獨採用beta blocker更有用。

Esophageal varices (EV,食管靜脈曲張) are abnormally enlarged veins in the esophagus(食道) that occur when portal hypertension (門靜脈高壓症) obstructs(阻斷) normal blood flow to the liver and causes the blood to back up into the esophageal vessels. Variceal(靜脈曲張) rupture(破裂) is a life-threatening condition. Approximately one third of cirrhotic patients with esophageal varices bleed, and the mortality rate associated with first bleed may be as high as 50%. 約有1/3的肝硬化病人有靜脈曲張出血,而加上第一次出血這個因素,其死亡率高50%。

The World Gastroenterology Organization (世界胃腸病學組織) practice guideline for esophageal varices in patients with cirrhosis and medium or large varices, but no hemorrhage (出血), recommends nonselective beta blockers (propranolol or nadolol) or endoscopic variceal ligation (EVL,內視鏡的靜脈曲張縫合術) for prevention of first variceal hemorrhage for patients at highest risk, and propranolol or nadolol for those who are not high risk or in whom EVL is not tolerated.
