Results Contrast CT or MRI showed prominent irregular circular or nodular enhancement in 14 of 16 cases (64%),can not distinguished from postopertative changes, radioinjury, tumor residue or recurrence.Among them, 9 cases showed tumor residue or recurrence based on significantly increased FDG uptake, 5 were confirmed by pathologic study. The other 5 cases of cerebral necrosis and 2 cases with postoperative cerebral malacia demonstrated FDG uptake defects.

结果 16例中87.5%(14例)CT和MRI表现不规则环形或结节状明显强化，不能准确作出手术后改变和放射治疗后脑损伤、残存肿瘤或肿瘤复发的诊断；其中9例残存肿瘤或肿瘤复发病灶18F-FDG PET影像表现为葡萄糖代谢明显增高，有5例得到手术病理证实；另5例术后放射治疗后脑损伤患者和2例术后软化灶18F-FDG PET影像均显示局部病变区为放射性分布缺损或明显低下。

In contrast, the ontogeny of call usage and comprehension is stongly influenced by experience in several nonhuman primates, and possibly in some birds (Cheney and Seyfarth 1990; Hauser 1996; Marler 1991), with benefits accruing to individuals that can learn to use call types and subtypes in new ways.

相反，对一些非人类灵长类来说，合体发育过程中鸣叫的使用和理解能力受经验的强烈影响，尤其是对一些鸟类来说（切尼和塞法特1990；豪瑟1996年，马勒1991年），个体积累的利益是可以学习使用呼叫类型和亚型。

Finally, by means of investigating the Chinese classical garden and nature reserve, considering the effect of visual characteristic, the psychology feeling, history and culture, this paper puts forward to a kind of conception of the landscape of low luminance and weak contrast based on mesopic vision creatively, and then constructs the corresponding theory of landscape lighting.

最后在调研古典园林、自然保护区等对象的前提下，考虑人的视觉特点、心理感受、历史、文化表达等因素的影响，结合定量研究，创造性的提出基于中间视觉的低亮度、弱对比景观理念，并建构了相应的景观照明理论。

Objective To study the changes of contrast sensitivity in mesopic and photopic condition caused by different ablation depth, and to evaluate visual functional state after LASIK. Method The study was taken in 72 eyes of 37 myopia patients received LASIK.

目的 研究准分子激光原位角膜磨镶术(Laser in situ keratomileusis，LASIK)术后不同切削深度患者暗视／明视下对比敏感度的差异，评估LASIK术后患者视功能状态。

Data for 4,228 cases and 84,540 controls matched on age and follow-up time were analyzed by using conditional logistic regression, adjusted for sex, age, health status, health care utilization measures, exposure to contrast agents, and nephrotoxic medications.

对于所有的服用NSAIDs者而言，在30天之内开始治疗，其发生急性肾衰竭的危险性最高（调整率比=2.05，95%置信区间：1.61，2.60）。

In contrast, exposure to ectopically expressed noncanonical Wnt11 markedly decreased the expression of Oct-4 and Nanog and induced mRNA expression (quantitative real-time reverse-transcription polymerase chain reaction) of cardiac-specific genes (Nkx2.5, GATA-4, atrial natriuretic peptide,- and -myosin heavy chain, and cardiac troponin T) by day 3 with subsequent progression to a pattern characteristic of the cardiac fetal gene program.

对比之下，接触到非典型wnt11能明显降低Oct-4 和 Nanog表达和在第3天出现诱导心脏特异性基因（Nkx2.5，GATA - 4，心房利钠肽，- and -肌球蛋白重链，肌钙蛋白T）mRNA的表达（应用反转录聚合酶链式反应实时定量），随后逐渐表达为心脏胎儿基因。

In contrast, Web isits are structured consultations focused on nonurgent chief complaints (e.g., cough), inoling menus of questions tailored to the problem, brief answers by the patient, and a response from the physician proided within a certain period.

我们采用的电子医疗模型除了可以安全地进行网络信息交流以外，主要提供以下四项服务：在线预约安排，电子处方补充，综合的通信联系，医生的系统登陆。综合的通信联系使病人可以在线咨询一些简单的问题，从而减少了许多电话访问（如，我下次就诊之前需要先拍一个胸片吗？

Induction of apoptosis by Etoposide was associated with upregulation of mRNAs for the BH3 only proteins Noxa, and to a lesser extent, Bim. In contrast, the expression levels of mRNAs for PUMA remained unchanged before and after treatment with Etoposide.

Noxa和PUMA主要受p53调节，细胞DNA损伤后通过p53可以上调Noxa和PUMA的表达［1］； Bim主要结合在微管动力蛋白上，受到细胞因子去除、Ca2+流出、紫外线照射、微管动摇和紫杉醇等刺激后可以转移到线粒体膜上［2］，从而发挥促凋亡活性。

In contrast,the expression levels of Lb est2 in nymphal stages are lower than that in adult stage.2 Gene cloning of AChE and mRNA expression level in L.entomophila2.1 Gene cloning and sequence analysis of AChE in L.entomophilaTwo full length cDNA encoding AChE were cloned from L.entomophila by the methods of RT-PCR and RACE,named Le ace1(GenBank Accession No.:EU854149) and Le ace2GenBank Accession No.

CarE基因在不同发育阶段mRNA表达量的分析结果表明，Lb est1的表达量随着该虫生长发育的进行逐渐降低，至成虫期时表达水平最低；相反，L6 est2在若虫期表达水平较低，而在成虫期表达水平最高。2嗜虫书虱乙酰胆碱酯酶基因克隆及其mRNA表达水平研究2.1嗜虫书虱乙酰胆碱酯酶基因克隆及序列分析利用RT-PCR和RACE技术成功克隆获得嗜虫书虱2个AChE基在的全长序列，分别命名为Le ace1(GenBank登录号：EU854149)和Le ace2(GenBank登录号：EU854150)。
