患者女，39岁。因"双侧膝关节疼痛5个月，干咳2个月，咯血3天"入院。查体：浅表淋巴结未及肿大，杵状指。双肺呼吸音清，未闻及干湿啰音。胸部CT示左肺门占位性病变，纤维支气管镜在左主支气管末端见新生物，活检报告为低分化腺癌。X线见双股骨下段骨膜增生。此表现为（）
A.类癌综合征
B.类风湿关节炎
C.滑膜炎
D.骨膜炎
E.肺性肥大性骨关节病
参考答案：E
解析：肺性肥大性骨关节病多见于肺腺癌患者，发生率12%左右，其次也可见于肺鳞癌。主要临床表现为骨的大关节疼痛，杵状指、趾，X线见长骨骨膜增生或骨膜炎可作为诊断依据。
| When you first drift off into slumber, your eyes will roll about a bit, your temperature will drop slightly, your muscles will relax, and your breathing will become quite regular. Your brain waves slow down a bit, with the alpha rhythm predominating for the first few minutes. This is the first stage of sleep. For the next 30 minutes or so, you will drift down through Stage 2 and Stage 3. The lower your stage of sleep, the slower your brain waves will be. About 40-60 minutes after you lose consciousness, you will reach the last stage. Your brain waves will show the delta rhythm. You may think that you stay at this deep stage all the rest of the night, but that turns out not to be the case. About 80 minutes after you fall into slumber, your activity cycle will increase slightly. The delta rhythm will disappear, to be replaced by the activity pattern of brain waves. Your eyes will begin to dart around under your closed eyelids. This period of Rapid Eye Movements lasts for 8-15 minutes and is called REM sleep. During both light and deep sleep, the muscles in your body are relaxed but capable of movement. As you slip into REM sleep, a very odd thing occurs -- most of the voluntary muscles in your body become paralyzed. Although your brain shows very rapid bursts of neural activity during REM sleep, your body is incapable of moving. REM sleep is accompanied by extensive muscular inhibition. |
