患儿10岁,胫骨中上段慢性骨髓灸,一般情况好,体温不高,局部有流脓窦道, X线片有4cm长整段死骨,周围有不连续包壳。当前的主要治疗是

A.手术摘除死骨,填入庆大霉素链,3周后取出,松质骨植入

B.手术摘除死骨,肌瓣填塞消灭死腔

C.手术摘除死骨,置入细塑料管,每日经管滴入抗生素

D.患肢长腿石膏管型固定,开窗换药

E.局部换药,保持引流通畅

答案

参考答案:D

解析:[解题思路] 慢性骨髓炎有整段死骨,周围包壳不连续,其本身即有发生病理骨折可能。如此时摘除死骨,骨膜将失去内衬而塌陷,新骨形成将受到很大影响,甚至造成骨缺损。故正确的处理是给予外固定(长腿石膏管型),开窗定期换药,待包壳充分形成后,再手术摘除死骨。[命题规律] 考察“慢性骨髓炎的治疗”。必须掌握。

Wearing ties was originally the mark of Britain’s most powerful classes, which made the tie itself a symbol of power and respect. And that led it to be adopted by a much larger tribe-the business tribe.

You cannot wear a tie if you work with machinery. So wearing a tie became a sign that you were a man who used your brain to make a living, rather than your hands. It showed you were serious. It showed you were a professional. It meant that everyone who wanted a job in business had to wear one. It was just impossible to take seriously a man who didn’t wear a piece of colored silk around his neck.

This is how millions of people came to be wearing ties across the world. They are part of the uniform of business.

“Ties offer a point of indifference,” says John Milne, head of the British Guide of Tie Makers, “They give a chance to say something about their own personality.”

So if you happen to meet a man with a very brightly colored tie, there is a good chance that he is the office joker. There is also a good chance that he will be wearing brightly colored socks.

Is there a future for ties? The signs are not promising. Tie wearing seems to be rare among the new bread of entrepreneurs(创业者) in the Internet and new technology industries. Many political leaders, including former British Prime Minister Tony Blair, now go without ties. This shows they are men of the people-but not the people wearing ties.

Up until around 1960, it was common for men across the western world to wear hats as part of their business uniform. That changed with the election of John F. Kennedy to the presidency of the United States. Kennedy never wore a hat-in fact his nickname was “hatless Jack”. Seeing that the most powerful man in the world did not have to wear a hat, millions of other men decided that they did not have to, either. Hats simply vanished across the Western world. Perhaps “tieless Tony” (former UK Prime Minister Tony Blair) will have the same effect as “hatless Jack”.
