问题 单项选择题

患者男,30岁。左腮腺后下极腺淋巴瘤2cm×3cm大小,进行区域切除术,术中发现腮腺下极有数个淋巴结,对这些淋巴结的处理应是()

A.无需特殊处理

B.保留,但术后需放疗

C.保留与瘤体粘连的淋巴结

D.与肿瘤发生有关,应摘除

E.术中冷冻切片决定是否切除

答案

参考答案:D

解析:腺淋巴瘤唯一的治疗方法是手术切除。因目前不断有报告其复发者,这可能与其具有肿瘤多发性的特征有关。保留面神经的腮腺浅叶切除或腺叶大部切除是最好的手术方法。手术中应将腺体内的淋巴结尽量摘除,以防以后发生新的病变。所以此患者在手术中发现腮腺下极有数个淋巴结需要摘除,所以D正确,故选D。

Every baby born a decade from now will have its genetic code (基因编码) mapped at birth, the head of the worlds’ leading genome sequencing (基因图谱) company has predicted.

A complete DNA read – out for every newborn will be technically possible and affordable in less than five years, promising a revolution in healthcare, says Jay Flatley, the chief executive of Illumina. Only social and legal problems are likely to delay the age of “genome sequences,” or genetic profiles. By 2019 it will have become routine to map infants’ genes when they are born, Dr Flatly told The Times.

This will open a new approach to medicine, by which conditions such as high blood pressure and heart disease can be predicted and prevented and drugs used more safely and effectively.

A baby’s genome can be discovered at birth by a blood test. By examining a person’s genome, it is possible to identify raised risks of developing diseases such as cancers. Those at high risk can then be screened more regularly, or given drugs or dietary advice to lower their chances of becoming ill.

Personal genomes could also be used to ensure that patients get the medicine that is most likely to work for them and least likely to have side – effects.

The development, however, will raise legal concerns about privacy and access to individuals’ genetic records.

“Bad things can be done with the genome. It could predict something about someone – and you could possibly hand the information to their employer or their insurance company.” said Dr Flatley.

“People have to recognize that this horse is out of the barn, and that your genome probably can’t be protected, because everywhere you go you leave your genome behind. Complete genetic privacy, however, is unlikely to be possible”, he added.

As the benefits become clearer, however, he believes that most people will want their genomes read and interpreted. The risk is nothing compared with the gain.

66.What does the underlined sentence “… this horse is out of the barn” mean?

A.Genetic mapping technique has been widely used.

B.Genetic mapping technique is too horrible to control.

C.People are eager to improve genetic mapping technique.

D.people can’t stop genetic mapping technique advancing.
