某男性患者，68岁。发热伴右上腹钝痛2天，恶心，食欲下降、乏力。继往有糖尿病史。查体：T39．4℃，右下胸及肝区叩击痛，右上腹肌紧张及触痛。X线胸腹部检查示：肝影增大伴局限性隆起，右膈肌上抬。F-FDG PET示肝右叶放射性分布局灶性异常浓聚，SUVave5．7，SUVmax8．6。

有关F-FDG PET临床作用的说法，不正确的是

A:炎症的严重程度与局部F-FDG的浓聚程度具有一定的相关性 B:特异性鉴别肝细菌性脓肿与肝细胞癌 C:炎症病灶摄取F-FDG的量受患者血糖水平的影响 D:F-FDG炎症显像有助于临床急性炎症的快速诊断 E:应用于临床的炎症谱广，各种炎症病灶大多可灵敏摄取F-FDG

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。

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

Many in the Middle East have difficulty in adjusting themselves to the new situation created by the departure of the imperial powers. For the first time in almost 200 years, the rulers and people of the Middle East have to accept the final responsibility for their own affairs, to make their own mistakes and to accept the consequences. This is difficult to internalize, even to perceive, after so long a period. For the entire lifetimes of those who formulate and conduct policy at the present time and of their predecessors for many generations, vital decisions were made elsewhere, ultimate control lay elsewhere, and the principal task of statesmanship and diplomacy was as far as possible to avoid or reduce the dangers of this situation and to exploit such opportunities as it might from time to time offer. It is very difficult to forsake the habits not just of a lifetime but of a whole era of history. The difficulty is much greater when alien cultural, social and economic preeminence continues and even increases, despite the ending of alien political and military domination.
Military and to a growing extent political intervention by the West has indeed ended, but the impact of its science and culture, its technology, amenities and institutions remains and even increases. As in other parts of the non-Western world, this impact has been and will be enormous. In these circumstances, it is natural that Middle Easterners should continue to assume—and proceed on the assumption—that real responsibility and decision still lie elsewhere. In its crudest form, this belief leads to wild and strange conspiracy theories directed against those whom they regard as their enemies—Israel, and more generally the Jews, the United States, and more generally the West. No theory is too absurd to be asserted or too preposterous to be widely and instantly believed. Even among more responsible statesmen and analysts, a similar belief in alien power, albeit in a less crude form, often seems to guide both analysis and policy. Some even go so far as to invite outside intervention, presumable in the belief that only outside powers have the capacity to make and enforce decisions. A case in point is the constant appeal to the United States to involve itself in the Arab Israel conflict, oddly coupled with the repeated accusation of "American imperialism. "
This state of mind is likely to continue for some time, with appeals for support or even intervention to the United States, to Russia and even to the European Union. In time, no doubt, Middle Eastern governments and people will learn how to use this window of opportunity to the best advantage—that is, of course, if the window remains open long enough.

A:they were rather backward and in bad need of foreign assistance B:they were accustomed to being ruled by an alien force C:they were plunged into war after the departure of the imperial powers D:the imperial powers left them nothing but disorder
