问题 单项选择题

关于FDP和D-二聚体测定的叙述,下列哪项是正确的()

A.FDP是指纤维蛋白原的降解产物,不包括纤维蛋白的降解产物

B.FDP增高是DIC的决定条件

C.FDP增高是体内纤溶亢进的标志,可以鉴别原发与继发纤溶

D.FDP增高主要见于容易发生DIC的基础疾病

E.D-二聚体是原发性纤溶的标志

答案

参考答案:D

解析:FDP是纤维蛋白原(Fbg)和纤维蛋白(Fb)被纤溶酶降解后产物的总称,所以又称总FDP。当FDP增高时,应当鉴别是否为DIC,为此还必须根据临床表现和其他凝血一纤溶系检查的结果综合判定,因为FDP增高不是DIC的决定条件。D-二聚体增高是诊断DIC的辅助条件之一,但在深部静脉血栓、肺栓塞、动脉瘤、卵巢癌、急性早幼粒细胞白血病时,D-二聚体也增高。D二聚体是继发性纤溶的标志。

     Several days ago, a Beijing-based IT company fired about 400 people overnight. No one had expected

the job cuts, which broke with traditional ways of letting go of workers in China. Moreover, what was

special about this case was that the day before the 400 were fired, they all received from their boss a

gift-the book "Who Moved My Cheese?" The book-a bestseller in the US-is being used by men and women

to deal with changes in their lives and work. Some large organizations, including Coca-Cola, Kodak and

General Motors, ask their employees to read it to encourage them to be active towards changes. Cheese is

something related to everyone's livelihood-our jobs, the Industries we work in, relationships and love as well.

With China's official entry into the WTO, the whole nation will face more changes and challenges. So what

should we do once this "cheese" on which we are so dependent is moved? "Whatever challenges and

changes we meet, we should face up to them bravely", Jiang Hengwei, a civil servant said after reading the

book. Professor Zhang Yang in Renmin University of China agrees. "We should change our way of thinking.

The coming competitive foreign companies and products provide us with great chances to learn from them

and improve our own products to meet international standards and be more competitive." "With hard work

and wisdom, we will create a much larger and better piece of cheese." Zhang smiled confidently.
