女性，35岁，慢性腰痛半年余，逐渐加重，与劳累有关。近2个月来伴右臀及右卜肢后外侧痛，无明显低烧、盗汗等症状，但体重有减轻。检查见腰僵直，活动受限，下腰有压痛及叩痛。腰椎X线片显示腰(下标)4-5间隙变窄，相邻椎体有破坏。其诊断最可能是

A．腰_4-5椎间盘感染

B．腰_4-5椎问盘突出

C．腰_4-5椎间盘退行性变

D．腰_4-5椎体结核

答案

参考答案：D

解析：
[考点] 脊柱结核
[分析] 年轻人，慢性腰痛，劳累后加重。虽无明显的结核中毒症状，但有休重下降。腰僵直，活动受限，下腰有明显压痛丛叩痛，提示有骨病变存在。X线片示间隙变窄，相邻椎体破坏，旱边缘型椎体结核表现，因此考虑其诊断最可能是腰_4-5椎体结核。另外在X线片上还应注意有无腰大肌影增宽，考虑有无寒性脓肿存在。体检时也应注意有关部位(如髂窝、腹股沟、腰三角等)有无寒性脓肿。该患者伴右臀及右下肢后外侧痛，系结核病灶刺激神经根所致。腰间盘突出及退行性变不应有椎体破坏。椎间隙感染可急性或慢性发病，常有发热等症状，X线片可见间隙变窄、相邻椎体缘骨质呈进行性骨化性改变。

The simplest way to say it is this: I believe in my mother. My belief began when I was just a kid, who    36   becoming a doctor.
My mother was a domestic（佣人）. Through her work, she observed that   37   people spent a lot more time reading than they    38   watching television. She announces that my brother and I    39  watch two to three pre-selected programs during the week. With our   40  time, we had to read two books each from the Detroit Public Library and   41   written book reports to her. She would mark them up with check marks and highlights. Years later we realized her marks were a    42  . My mother was illiterate（文盲）.
When I entered high school, I was a    43   student, but not for long. I began to like fancy clothes. I wanted to    44   other guys. I went from an A-student to a B-student to a C-student. One night my mother came home from her various jobs and I    45   about not having enough Italian knit shirts. She said, “Okay, I’ll give you all the money I    46   this week scrubbing floors and cleaning bathrooms, and you can buy the family food and pay the bills. With the money    47  , you can have all the Italian knit shirts you want.” I was very    48   with that arrangement but once I got through allocating（分配）money, there was   49   left. I realized my mother was a financial genius（金融天才）to be able to keep the roof over our heads and any kind of food on the table, let alone buy    50  . I really realized my desire wasn’t going to get me    51  . Success requires intellectual preparation. I went back to my    52   and became an A-student again and eventually I    53   my dream and I became a doctor.
My story is really my mother’s story—a woman with    54   formal education who used her position as a parent to change the lives of her children. There is no job    55   than parenting. This I believe.
