A.多发生在距幽门2~3cm以内

B.指十二指肠球部后壁溃疡

参考答案:C

解析:球后溃疡是指十二指肠球部远端的溃疡,并不是球部后壁的溃疡,球后溃疡具有球部溃疡症状,但疼痛更剧,可向右肩放射,更易出现出血、穿孔,由于部位较下,器械检查更易漏诊。

The TV shows a baby’s pram (婴儿车) rolling off a train platform as the mother makes a mad rush to save her son, but she is too late and it falls onto the rails in front of an incoming train. This heart-stopping scene happened yesterday at Ashburton station in Melbourne, Australia. But the story has a happy ending: the six-month-old baby survived with just a cut on his forehead, although the pram was dragged about 35 metres by the braking train. The nurse Jon Wright said the boy just “needed a feed and a sleep” and didn’t need to stay in hospital.

“Luckily, he was strapped (绑) into his pram at the time, which probably saved his life. I think the child is extremely lucky, ” Wright told the Herald Sun newspaper after the baby was taken to hospital with minor injuries.

Fortunately the train was already slowing down to stop at the station so it stopped quickly when the driver put on the brakes as soon as he saw the pram fall in front of him. Rail firm Connex is to look into how the pram rolled off the platform. The accident came one day after Connex started a child safety awareness activity warning parents to keep babies strapped into their prams at all times while on platforms.

The accident happened at the same time as the “balloon boy ”story in the US, in which a six-year-old Colorado boy was reported to be trapped in a flyaway balloon. However, he was later found hiding in the family’s garage. Many people believe that it had all been a publicity stunt by the parents. No such doubts surround the baby on the train platform.
