下列选项中，不属于抗ENA抗体的是
A．抗Sm抗体
B．抗RNP抗体
C．抗SSA抗体
D．抗rRNP抗体
E．抗dsDNA抗体
参考答案：E
解析：[解释] 抗ENA抗体包括：①抗Sm抗体：是诊断系统性红斑狼疮(SLE)的标记抗体之一，特异性达99%．，但敏感性仪25%，而且不代表疾病活动性；②抗RNP抗体：常与SLE的雷诺现象和肌炎相关，对SLE诊断特异性不高；③抗SSA抗体：常出现于亚急性皮肤型红斑狼疮(SCLE)、SLE合并干燥综合征时；④抗SSB抗体：其临床意义与抗SSA抗体相同，但阳性率低于抗SSA抗体；⑤抗rRNP抗体：Ⅲ现此抗体则代表SLE的活动，同时往往指示有神经精神狼疮及其他重要内脏损害。而抗dsDNA抗体也是诊断SLE的标记抗体之一，而且与SLE的活动性密切相关，但是不属于抗ENA抗体。

"What? Dance? Is that 2 ?" I asked myself. Mary was not such kind of girl. She was a quite 3 one. I had never seen her wearing colorful clothes. In fact, she really did not know 4 to dress up.

I knew I would have a 6 time before her turn,for I had no sense of art, 7 her performance was worth watching, no matter how long I would wait. Time went 8 , I tried my best not to fall asleep. Just then, came the 9 , "Let' s welcome the next exciting dance-Latin!" Hearing this, I opened my eyes as large as possible, 10 to lose anything. Wearing a golden and shining skirt, Mary appeared. She 11 with a sweet smile, looking like a pretty butterfly flying... I could 12 believe my eyes. After all the performance ended, I 13 her at the gate. "Hi!" she stood in front of me with her crystal(水晶) shoes. "How do you feel?" "Fantastic!" I answered. "Ha, ha. I knew 14 would be." She could not hide her excitement, laughing 15 a child. At that time, I realized that every girl has a pair of special shoes which are like the crystal shoes of Cinderella. | ||||
