乳腺癌钼靶X线的表现为()。

A.密度均匀的肿物,边界较清晰、整齐

B.密度均匀的肿物,可见圆圈及小斑片状钙化

C.片状或结节状致密影,和周围腺体组织密度类似

D.高密度影肿物,边缘呈毛刺状,可见小簇状、沙砾样钙化

E.密度不均匀,边界不清楚

答案

参考答案:D

解析:乳腺癌在钼靶上的重要表现首先是 * * 内高密度肿块,多表现为边缘有毛刺状浸润表现,可见小叉状、沙砾状、成簇的钙化点。腋窝淋巴结有肿大者也可以在钼靶的斜位片上显示。其中某些乳腺癌可仅以成簇的钙化点为表现。乳腺的良性肿物钼靶影像主要为质地均匀中等密度肿物,边缘光滑,如有钙化则主要为圆圈、小斑片的钙化。

Isn’t it cool to surf in summer? You catch a wave and enjoy the ride with skill and gift. Surfing is not only our favorite pastime, though. A group of penguins(企鹅) enjoy the sport as much as we do. And they display their excitement and skills in the new animated(动画) film Surf's Up , which came out on June 6, in the US.

Teenage penguin Cody Maverick lives in Antarctica and loves the sport. He desires to learn from Cody's idol is Big Z, a great penguin surfing king.

He is different from other penguins, who work in processing factories. His brother and mother are not supportive of him. He really wants to get away. Cody believes that winning will bring him the admiration and respect he desires. He's given the chance to escape when Mikey Abromowitz, a talent scout (星探), comes to Antarctica to look for gifted penguins for a surfing competition on an island named Pen Gu.

Cody's really excited, but, during his show, there are no waves and he chokes. But he knows he can't give up. He runs after Mikey's whale. And he begs until Mikey agrees to take him to Pen Gu.

There Cody meets Lani, the island's beautiful lifeguard, as well as his main rival (对手), the surfing champion Evans. The cocky Evans shows no respect for Big Z, which makes Cody angry. In order to defend his forever idol, he challenges Evans to a surfing match, only to suffer a terrible defeat.

Lani takes Cody to the island doctor. As they spend time together, Cody realizes that this doctor is really Big Z himself and begged Big Z to teach him.After Big Z learns the cause of his injury, he begins to train Cody and help him make a good surfer.

问答题

1.某记者因为眼睛轻微不适前往方庄第一医院就诊。医生诊断的结果是结膜炎,在处方上开出的是江西萍乡制药厂生产的5毫升装盐酸环丙沙星滴眼液。这家社区医院划价每支15.7元。2.记者随后在相距百米的方庄购物中心,看到药品专柜上一模一样的滴眼液售价仅为6.6元。两者价格相差2.3倍。3.记者又来到堪称国内最高规格的一家三级甲等医院,想在这里得到一个放心的药价。结果有些出人意料:这种滴眼液又派生出一个新售价——每支12元。4.按照环丙沙星滴眼液中的使用说明书,记者按图索骥拨通了江西萍乡制药厂的电话。这个厂销售科彭科长报出了出厂价:“一次进货一箱以上,每支价格3.8元。”5.据北京市物价局副处长安群介绍,江西萍乡制药厂生产的5毫升装环丙沙星滴眼液,属于企业按规定的作价办法自定价格的药品,它必须先到北京市物价局进行登记后才能销售。在加上国家规定的正常差率后,这种药品在北京市场登记公布的价格是:每支批发价为5.75元、零售价为6.6元。安群说,无论是在药店还是在医院出售,可以低于北京市物价局公布的药品价格,但决不允许高出。6.按照药品价格管理办法,厂家按不同的剂型给批发商20%左右的进销差翠,批发商再给零售商15%的批零差率。此外,对企业按作价办法定价的药品,可以有50%的工商让利。这些都属正常的经济行为。7.如果按厂家报的实际价格进行推算,环丙沙星滴眼液的批发价大体上应为4.75元,零售价应为5.46元。8.记者随后拨通了这种药品在北京的两家批发商——燕京医药公司和燕京第一批发部的电话。接电话的两位女同志都不愿意透露从厂家的进价,但比较爽快地报出“批发价”:规定批发价——每支5.75元的八六折,就是4.95元。燕京第一批发部接电话的女同志说:“给医院一般都是八六折”。9.据业内人士透露,相比药店零售而言,医院开药的中间环节要复杂得多。一般情况下,厂家聘请医药代表或业务员,由他们负责向各医院进行“公关”。一所医院需要攻下的关口至少有:医院负责人、负责进药的主管和经办人、相关科室负责人和医生。每个关口都要暗地里“奉送”一定的回扣,从2个百分点到15个百分点不等。10.知情者称,医生开出一支环丙沙星滴眼液,可提取占零售价10%的“好处费”。

根据上述材料,自选某一角度,自拟题目,写一篇1000字左右的文章。要求:联系实际,观点鲜明,条理清楚,语言流畅。
