新生儿湿肺的主要X线表现

A.肺透亮度增加伴双侧气胸
B.肺透亮度增加伴节段性肺不张
C.肺透亮度增加伴纵隔气肿
D.肺透亮度降低弥漫性均匀网状颗粒影伴支气管充气征
E.斑片状、面纱或云雾状密度增高影

答案

参考答案:E

解析:湿肺多见于足月儿。系肺淋巴和(或)静脉吸收肺液功能暂时低下,使其积留于淋巴管、静脉、间质、叶间胸膜和肺泡等处,影响气体交换。生后数小时内出现呼吸增快(>60次/分),但吃奶佳、哭声响亮及反应好,重者也可有发绀和呻吟等。听诊呼吸音减低,可有湿啰音。X线胸片显示肺气肿、肺门纹理增粗和斑点状云雾影,常见毛发线(叶间积液),对症治疗即可。一般2~3天症状缓解消失。

Board, But Not Boring

Roll the Dice and Take a Chance on Something New…

Are you vacationed-out, tired of video-gaming, waterlogged by too many trips to the pool and ready to scream if you see one more “SpongeBob” rerun?

In other words, are you bored with summer?

We’ve got a suggestion: Kill that boredom with some great board boredom games. We went to game expert Lizzy Palmer of Barston’s Child’s Play in the District and ask for suggestions. All the games you see on this page are a ton of fun, she said, and there are sure to be at least one or two that you don’t already have.

Maptangle

Borderline Games

Ages 7 and older, 4 to 6 players, $24.95

This clever take on the classic game of Twister challenges your gymnastic and geographic skills at the same time. A huge floor map of the world serves as the game board. There are lots of geographic elements: countries, oceans,  rivers, deserts, even man-made landmarks. A deck of cards tells you where to put one foot, then the other. The round is over when someone falls.

Jungle Speed

Ages 7 and older, 2 to 8

players, $25.99

This is a fast-paced shape-recognition game. A wooden totem (图腾柱) sits in the middle. Players flip (翻) over cards one at a time. When your card matches another, be the first to grab the totem so that you can give your card to the loser. But be careful: Some cards look the same but aren’t!

Enchanted Forest

Ravensburger Ages 6 and older, 2 to 6 players,

$24.99

A classic memory game. Take a winding path through the forest and check under the trees for

fairy-tale treasure. Remember what you saw so that when you need a particular treasure you can

go back to that tree to get it. Cool rule: You can split your dice (骰子) roll—for example, move five spaces in one direction and two in the other to land at the right tree.

Go fish for Wildlife Birdcage Press All ages, $9.95

Birdcage has several decks (副) of cards that are more like trading cards. You fish for sea creatures,  reptiles, wild animals. Each deck has instructions for several card games, and each card has great photos and fun facts. Great for a trip.

HedBanz Funrise Ages 6 and older, 2 to 6

players, $13.99

Put on a headband and slip in a card that shows an animal or thing. Everyone else can see it but you.Ask questions until you guess what it is—but do it before time runs out!
