患者男，32岁，教师，江西上饶人，因“发热10+d”来诊。10d前患者开始出现发热，体温37.2～39.6℃，伴畏寒、乏力、头晕，热退后头晕消失。在当地医院应用头孢曲松、利巴韦林（病毒唑）治疗无效。有乙型病毒性肝炎肝硬化病史1年余，拉米夫定治疗6个月。近1年余未曾出外旅游。查体：T38.3℃；皮肤、巩膜中度黄染，口腔未见白斑，颈软，未见肝掌、蜘蛛痣，全身淋巴结未及肿大；心、肺未见异常；腹软，无压痛、反跳痛，肝未及，脾肋下1.5cm，移动性浊音（＋）；双下肢无水肿，四肢肌力、肌张力正常；布鲁津斯基征（－），克尼格征（－），病理反射未引出。肝功能：Alb23.1g/L，Glob36.6g/L，ALT43U/L，AST63U/L，CHE812U/L，TBil81μmol/L，DBil41μmol/L，γ-GT47U/L，PT26.4s；HBV-DNA：低于检测限；乙型肝炎五项：HBsAg（＋）、HBeAg（＋）和HBcAb（＋），余阴性。

结合入院后抗生素治疗和体温变化之间的关系，患者住院以来前后2次发热原因若是一元的，最有可能引起发热的原因是（）（提示：考虑并发二重感染（口腔白色念珠菌感染），予氟康唑200mg静脉滴注治疗，次日体温明显减退，治疗3d体温正常，应用氟康唑5d后停药。患者自觉腹胀、乏力也明显缓解。继续护肝、利尿、抗乙型肝炎病毒治疗；17d后体温再次上升，可达39.0℃以上，且腹胀、乏力再现，并有加重趋势。血常规：Hb80g/L，RBC2.11×10¹²/L，WBC3.6×10⁹/L，N0.81，L0.04，PLT39×10⁹/L。肝功能：Alb46.8g/L，Glob26.2g/L，ALT31U/L，AST46U/L，CHE841U/L，TBil99μmol/L，DBil54μmol/L，γ-GT24U/L，PT31.3s。腹腔积液常规：黄色，清，WBC56/μl，李凡他试验（-）。腹腔积液蛋白定量：4.0g/L。仍然考虑可能是腹腔内一般细菌感染，予头孢哌酮＋舒巴坦治疗7d，仍有高热。停药2d，体温无变化。胸部CT：正常。）

A.药物热

B.病毒感染

C.淋巴瘤

D.结核病

E.机体深部脓肿

Almost every machine with moving parts has wheels，yet no one knows exactly when the first wheel was invented or what it was used for.We do know，however，that they existed over 5,500 years ago in ancient Asia.

The oldest known transport wheel was discovered in 2002 in Slovenia.It is over 5,100 years old.Evidence suggests that wheels for transport didn’t become popular for a while，though.This could be because animals did a perfectly good job of carrying farming tools and humans around.

But it could also be because of a difficult situation.While wheels need to roll on smooth surfaces，roads with smooth surfaces weren’t going to be constructed until there was plenty of demand for them.Eventually，road surfaces did become smoother，but this difficult situation appeared again a few centuries later.There had been no important changes in wheel and vehicle design before the arrival of modern road design.

In the mid­1700s，a Frenchman came up with a new design of road—a base layer(层) of large stones covered with a thin layer of smaller stones.A Scotsman improved on this design in the 1820s and a strong，lasting road surface became a reality.At around the same time，metal hubs (the central part of a wheel)came into being，followed by the pneumatic tyre(充气轮胎) in 1846.Alloy wheels were invented in 1967，sixty years after the appearance of tarmacked roads(柏油路)．As wheel design took off，vehicles got faster and faster.                          (2013·重庆，C)
