173布卢姆：（身穿燕麦色运动服，翻领上插着一小枝忍冬草，里面是时髦的浅黄色衬衫，系着印有圣安德鲁十字架的黑白方格花呢领带。白色鞋罩，臂上挎了件鹿毛色风衣，脚蹬赤褐色生皮翻毛皮鞋。将一架双筒望远镜像子弹带那样斜挎在肩上，头戴一顶灰色宽边低顶的毡帽。）你还记得吗，很久很久，多年以前，米莉——我们管她叫玛莉奥内特。刚断奶，我们大家曾一道去看过仙女房赛马会？

Methods On the basis of nasal anatomic dissection in 7 adult cadavers, a conception of "lateral nasal aponeurosis" was put forward and a new fixation technique for correcting epicanthus was used cliniclly in the following procedures: incision of the epicanthal fold, cantholysis and canthoplasty by pulling the new canthus medially and fixing it on the lateral nasal aponeurosis.

本文对7具尸体的鼻侧腱膜进行了解剖观察，从而提出鼻侧膜固定法矫正内眦赘皮畸形，即水平切开半月形赘皮，开大内眦角，将新内眦点向中央移位，并缝合固定于鼻侧腱膜上以重建内眦角，修剪新内眦角上下两侧的多余赘皮。

In general, medium shot plays an important role in narrative, while long shot, full shot, close shot and close-up affect more the expression of characters' psychology and the audiences' aesthema.

在现代蒙太奇修辞中，中景一般在叙事上发挥着重要作用，而远景、全景、近景、特写往往在表现人物心理和影响观众观影心理上起着重要的作用，让皮埃尔热内导演的《天使爱美丽》(2001)中体现了这一观点。

Terrier-like in his harassment of opponents and tigerish in the tackle, McMahon's combative aura helped fill the void left by Souness in the mid-Eighties, while his bone-shuddering midfield clashes with Peter Reid have since passed into Mersey derby folklore.

面对对方球员，他总是保持了很旺盛的斗志，并且时刻准备着放出凶猛的铲断。在上实际80年代中期索内斯缺阵的情况下，麦克马洪凭借这不屈的斗志填补了索内斯留下的空白。而自从与埃弗顿球员皮特·里德在比赛撞破骨头之后，马克马洪就也成为了默西塞德比的一段传奇。

The tumor is sessile, polypoid, or castlike and is characterized by the presence of innumerable papillary frondlike infoldings comprised of proliferations of columnar epithelial cells around the slender fibrovascular stalks that are supported by the connective tissue of the lamina propria.1 Occasionally, tumor spreads superficially along a variable length of the bile duct.

该肿瘤是无蒂、乳头样或脱落物样的，以及肿瘤表面特征性地存在无数乳头样叶状内折叠，这些乳头是由围绕纤细的以管腔的结缔组织为支撑的纤维血管茎增殖的柱状上皮细胞构成。肿瘤偶尔也会沿不同长度在胆管表面蔓延。

We found that 1 mutant EG4 cells showed typical characteristics of pluripotent stem cells which had no obvious difference with wild cells; 2 When induced by 10〓 M retinoic acid , mutant EG4 cells differentiated into adipocytes with high frequency compared with mutant cells, suggested that EGFR plays a role in adipocyte differentiation; 3 when injected into nude mice, mutant teratocarcinomas contained a large amount of connective tissues as well as skeletal muscle, while wild EG4 cells produced frequently cartilage, keratinocyte and neuroepithelium.

我们建立了稳定表达胞内区功能缺失的外源EGFR cDNA片段的EG4细胞，分析其生长分化特性，发现 1）突变型细胞可在未分化状态下维持长时间的增殖，表明EGFR对EG多能干细胞表型无明显影响；2）〓 M的维甲酸A(retinoid acid A，RA)诱导后，大部分对照组细胞分化为脂肪细胞，而突变型细胞分化为脂肪细胞的比例明显较少，表明EGFR在脂肪细胞的发育分化中具有一定的调节作用；3）畸胎瘤切片分析显示，突变型瘤组织分布有大量的未分化细胞和结缔组织，分化细胞以肌肉细胞为主；对照组瘤组织含丰富的角质上皮、软骨、神经管等依赖EGFR的分化组织。

Results: Bax immunoreactivity was detected in 44 out of 72 cases of cholangiocarcinoma and 8 out of 25 cases of normal control, in which bile ducts among lobules in normal parts aside of hepatocellular carcinoma tissues were observed.

结果：在72例CHC中，Bax阳性44例（61.1％）；用于对照的25例肝细胞肝癌的癌旁肝组织汇管区胆管上皮Bax阳性8例（32％）。bax在CHC中的表达强于正常对照组（P＜0.01），在其中53例高、中分化的CHC的表达强于在19例低分化CHC的表达（P＜0.01），在肝内胆管癌与肝外胆管癌的表达无显著差异（P＜0.05）。

Under the microenvironments of fruit bagging,Alternaria had always been the major fungi in different bags,sites of fruit and weather conditions during the whole growing season. As the secondary major fungi,Penicillium had always been after July and emerged later in inner bag and cortical pore than other sites.In the bag with which the inner bag was red and waxing,Trichoderma was isolated first in pericarp without cortical pore and inner bag as well as later in cortical pore after August.In \'Kobayashi\' bag which inner bag was red and waxing, Aspergillus and Fusarium were isolated in pericarp without cortical pore and cortical pore after bag removed.Alternaria and Penicillium were isolated in unbagging fruit and \'Qianwei\' bag which inner bag was red and unwaxing and the date Penicillium was isolated in CK was 45d later than bagging treatment.Under high temperature weather condition,there were no differences in the fungi population structure on fruit surface among all treatments.And the fungi population structure on fruit surface in bagging apple was more than that of unbagging ones under overcast and rainy condition.

在苹果套袋微域环境下，不同育果袋、果实不同部位、不同时期、不同气象条件下的真菌主要是链格孢霉，且在套袋后的整个生长季均可分离到；青霉为第二大真菌，在7月份后均可分离到，在非皮孔部位的出现要早于内果袋和皮孔部位；8月份后在内袋红色涂蜡的育果袋上分离出了木霉，其先出现在非皮孔处和内果袋，然后出现在皮孔处；曲霉和镰刀菌仅在内袋红色涂蜡的&小林&袋的非皮孔部位和皮孔部位于摘袋后分离出；在内袋为黑色且未涂蜡的育果袋和未套袋果上仅仅分离出链格孢霉和青霉，且青霉分离出的时期要比套袋果晚45d。
