Methods: On the basis of middle cerebral artery occlusion model in rats, free radicals were detected in hyperglycemic rats and normoglycemics.

建立大鼠左大脑中动脉梗死(Middle Cerebral Artery Occlusion，MCAO)模型，在证实高血糖可加重局灶性脑缺血损伤的基础上，检测正常和高血糖脑缺血后不同时间的自由基水平。

Objective To analyze the contrast enhancement appearances and patterns on dual phase helical CT scans in 21 cases with hepatic hypervascular metastases, and to discuss the value and pitfall of helical CT in diagnosing hepatic hypervascular metastases.

目的 分析 2 1例共 6 3个富血供肝转移灶在螺旋CT双期扫描中的表现，探讨螺旋CT在该病诊断中的价值和限度。

In this research, based on setting up the rat model of ischemic apoplexy successfully, we demonstrated there was down-regulation cerebral zone in its brain, which was manifested by hypoperfusion in the maginal and remote zone to infact area, hypoactivity of synapses and cerebral capillary endothelial cell to modulate microvascular.

本课题成功制作了缺血性卒中后遗症大鼠模型，并证实了下调脑区的存在，即梗死灶边缘区及远隔区存在低灌注现象，突触活性降低，脑微血管内皮细胞对脑微循环的调节机能下降。

Cancer-Testis antigens are specifically expressed in various types of human tumors but not in normal tissues except for testis. Among the CT antigens, NY-ESO-1 is the most immunogenically identified so far.

肿瘤免疫治疗，由于其具有抑制肿瘤细胞生长、杀灭残存肿瘤细胞和微转移灶的功效，因此辅助手术和化疗进行的肿瘤免疫治疗有可能成为肿瘤治疗中一个新的热点。

The main reasons for false negative of MRI were microscopic cancer foci and postoperative inflammative reaction.

局部活检区的镜下微灶残余和炎症反应是构成MRI对残余癌检出假阴性的主要原因。

ResultsIn group C and D hyperplasia of epithelium cell and infiltrations of inflammative cell in day 14 that were severe than that of day 7,ciliate cell was piece loss,the glands were hyperplasia（≥40% of group C,≤20% of group D）in windpipe,and pulmonary alveolus were congestion and dropsy.In group C the epidermis were pucked and connective tissue was hyperplasia in the skin,the quantity of hair ball and the sweat glands of group C and D in the food were significantly reduced than that of group A.

结果第14天时，C组、D组气管上皮鳞状化生，C组气管纤毛多呈片状缺损，而D组多呈灶状缺损；两组气管黏膜炎性细胞浸润均较第7天为重，伴气管浆液腺上皮黏液腺化生（D组≥40%、C组≤20%）、肺泡淤血、水肿。C组皮肤表皮呈不规则皱缩、毛球数明显减少；C组、D组足垫部皮肤表皮增厚、汗腺减少伴结缔组织增生。

The radiographic and histologic findings suggested infrapatellar bursal osteochondromatosis associated with a large, unresoled Osgood-Schlatter lesion.

影像学和组织学发现提示髌骨下粘液囊骨软骨瘤与一个大的未缓解的Osgood-Schlatter损伤灶相关。

With routine HE staining, focal inflammation occurred in the mucous membrane of DMC colon and that the neuronal vacuolus of the intermuscular nerve plexus degenerated, reduced and even disappeared.

常规HE染色下，DMC结肠粘膜下有灶状炎症，肌间神经丛神经元空泡变性、减少，甚至消失。

We describe a case of NLPHL showing a variant histologic pattern characterized by small and large clusters of lymphocyte predominance cells within nodules defined by follicular dendritic cell meshworks, associated with numerous neutrophils and areas of internodular fibrosis. Focally, the neoplastic cells had lacunar cell-like cytologic features.

在此，我们描述一例组织形态特殊的NLPHL，其形态学表现为以淋巴细胞为主的细胞排列成大小不等的结节，结节均由滤泡树突状细胞网网罗，结节内见中性粒细胞浸润，部分结节间见纤维化，局灶瘤细胞呈陷窝样。

Objective To analyse the clinical characteristics of intrahepatic calcification.

简介 目的分析肝内钙化灶的临床和影像特征。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
