问题 单项选择题

男性,16岁。反复膝关节血肿,APTF延长,CT延长,给BaSO4吸附血浆不能纠正,能被正常血清纠正。最可能的诊断是

A.血友病A
B.血友病B
C.遗传性FⅫ缺乏症
D.血脂性血友病

答案

参考答案:B

解析:本例为出血性疾病。APTT延长表明第一阶段内源性凝血途径凝血因子缺乏,包括Ⅷ、Ⅸ、Ⅹ、Ⅺ、Ⅻ因子。Ⅻ因子缺乏,临床常无出血表现。给BaSO4吸附血浆不能纠正,能被正常血清纠正,表明为Ⅸ因子缺乏,即血友病B。

Teaching my first child, Danae, to share her toys was the biggest challenge. To   36  this, we started inviting other children to play, which could help Danae discover that it’s   37  to share with others – a lesson I needed to   38  myself as well, as it   39 .
One evening Danac had   40 a friend, Natalie, to play with her. Their favorite was a children’s   41  game called Go Fish. That evening,   42  Natalie left, Danae came to me and said, “Mommy, I’d like to give these to Natalie tomorrow. They’re her favorites.”
She help up three cards from the Go Fish game. I tried to   43  that I didn’t want her to give them away because then our   44  wouldn’t be complete. “But I really want her to have them!” Danae   45 . I thought perhaps she didn’t understand that when she gave something away, it was gone   46 . So I tried again, saying, “  47  you give the cards to her, you can’t   48 them back tomorrow.”
A look of   49  came over Danae’s face. For a moment I was happy that she seemed to   50 . But then she smiled and said. “Well, that’s okay, I want her to have them anyway.”
What could I say to that? I sat   51  for a moment and then I realized I had been trying for so long to   52  her to share. Did it   53  that our Go Fish set would be   54 ? What mattered was that my daughter was learning the   55  of giving, that she was thinking about others instead of herself, and that she was trying to make her friends happy. Isn’t that what life is all about?
