问题 单项选择题 B型题

缺铁性贫血()

A.全血细胞减少

B.红细胞及血小板正常

C.红细胞及血红蛋白均减少

D.血小板减少

E.周围血大量原始和幼稚白细胞

答案

参考答案:C

解析:

1.再生障碍性贫血患者由于骨髓造血功能衰竭,造成全血细胞减少,但3种细胞减少的程度不一定平行。网织红细胞低于正常;血小板减少,出血时间延长;白细胞计数多减少,以中性粒细胞减少为主。 2.急性白血病患者的外周血可发现大量原始细胞及幼稚细胞。贫血轻重程度不等,一般属正常细胞性贫血。早期血小板轻度减少或正常,晚期明显减少。 3.ITP由于外周血存在血小板相关抗体,造成血小板减少;血红蛋白可正常或减少;白细胞计数多正常。 4.缺铁性贫血由于体内用来合成血红蛋白的贮存铁缺乏,使血红蛋白合成量减少,红细胞体积较小,为小细胞低色素性贫血;白细胞、血小板均正常。

Still seeking a destination for your weekend break? There are some places which are probably a mere wall away from your college.

King’s Art Centre

A day at the Centre could mean a visit to an exhibition of the work of one of the most interesting contemporary artists on show anywhere. This weekend sees the opening of an exhibition of four local artists.

You could attend a class teaching you how to ‘learn from the masters’ or get more creative with paint – free of charge.

The Centre also runs two life drawing classes for which there is a small fee.

the Botanic Garden

The Garden has over 8,000 plant species; it holds the research and teaching collection of living plants for Cambridge University.

The multi-branched Torch Aloe here is impressive. The African plant produces red flowers above blue-green leaves, and is not one to miss.

Get to the display house to see Dionaea muscipula, a plant more commonly known as the Venus Flytrap that feeds on insects and other small animals.

The Garden is also a place for wildlife-enthusiasts. Look for grass snakes in the lake. A snake called ‘Hissing Sid’ is regularly seen lying in the heat of the warm sun.

Byron’s Pool

Many stories surround Lord Byron’s time as a student of Cambridge University. Arriving in 1805, he wrote a letter complaining that it was a place of “mess and drunkenness”. However, it seems as though Byron did manage to pass the time pleasantly enough. I’m not just talking about the pet bear he kept in his rooms. He spent a great deal of time walking in the village.

It is also said that on occasion Byron swam naked by moonlight in the lake, which is now known as Byron’s Pool. A couple of miles past Grantchester in the south Cambridgeshire countryside, the pool is surrounded by the fields. The cries of invisible birds make the trip a lovely experience and on the way home you can drop into the village for afternoon tea. If you don’t trust me, then perhaps you’ll take it from Virginia Woolf – over a century after Byron, she reportedly took a trip to swim in the same pool.
