某男性患者，47岁。咳嗽2周入院。干咳，无咯血，无畏寒、发热，否认结核病史。一直从事银行业工作。血常规：WBC6.7×10/L，其中N52%,L40%,E0.8%.PPD(1:2000)试验：(±),ESR35mm/h。胸部CT示右下肺内基底段见一约1.6cm×1.8cm结节，无分叶、毛刺及胸膜牵拉征。为进一步鉴别结节性质，拟行F-FDGPET/CT显像。

F-FDGPET/CT显像前准备包括

A:禁食6小时以上 B:测定患者身高、体重及血糖水平 C:注射显像剂前及注射显像剂后至显像时患者处于安静、舒适的状态 D:显像前饮水 E:显像前排空膀胱 F:若血糖水平超过7.6mmol/L，则须注射胰岛素以减低血糖浓度至正常水平

对可能出现的F-FDGPET/CT征象的解读不正确的是

A:SUV低于2．0，考虑结节良性病变可能性大 B:SUV高于2.5，且延迟相SUV超过早期相SUV，考虑结节恶性病变可能性大 C:恶性肿瘤病变SUV与病灶病理分化程度呈正相关 D:恶性肿瘤病变SUV愈高，则患者预后相对愈差 E:若患者血糖水平增高，分析F-FDGPET/CT结果时应考虑血糖水平的影响 F:错构瘤常呈阳性结果

Across the Deserts

　　The SaharaDesertis the largest desert in the world. It stretches across Africa fromSenegaltoEgypt. TheSaharaDesertis an unfriendly environment. During the day it"s very hot, and at night it’s sometimes very cold. It is also difficult to find water in theSahara.

　　In 2006, Kevin Lin, Ray Zahab, and Charlie Engle decided to do something very difficult. They made the decision to run across the Sahara Desert 4,300 miles (6,920km). It seemed impossible to do, but they wanted to try. The three men liked to test themselves, and this would be a very big test.

　　On the morning of November 2, Kevin, Ray, and Charlie started their trip across theSahara. Every morning they began running at 5:00. At11 a.m. they stopped and rested until 5 p.m. Then they ran again until 9:30 in the evening. Each day they ran about 40 miles (64 km). Every day it was the same thing. They got up and ran. They listened to music on their iPods, and they ran and ran.

　　Kevin, Ray, and Charlie needed to eat a lot of food during their trip. Most people need about 2,000 calories of food each day. Kevin, Ray, and Charlie needed between 6,000 and 9,000 calories every day. That"s a lot of food! They also needed to drink a lot of water.

　　The three men had some problems on their trip, and many times they wanted to quit and go home. It was often very hot (140°F/60°C) during the day, and the heat made them sick. Their legs and feet hurt. Sometimes it was very windy, and they couldn"t see. One time they got lost. But they didn"t quit. After 111 days, Kevin, Ray; and Charlie successfully finished their trip across theSaharaDesert. They hugged each other and put their hands in the water of theRed Sea. Then they ran to a hotel to take a long shower.
