消化道癌雌孕激素受体阴阳性细胞的超微结构比较

取大肠管状腺癌Ⅱ级,无淋巴结转移者新鲜标本14例,以酶联组化法证实雌激素与孕激素受体均阳性者或均阴性者各7例,进行透射电镜下的超微结构观察。结果表明:受体阳性细胞、核暗、常染色质增多,呈细颗粒状,核仁以细颗粒状物为主。受体阴性细胞浆内游离核糖体明显增多。超微结构的不同提示两类癌细胞在代谢类型上存在着差异。     

消化道恶性肿瘤雌孕激素受体与癌胚抗原的相关性研究

利用酶联素和组化法和ABC免疫组化法进行88例消化道恶性肿瘤的雌激素受体(ER)、孕激素受体(PR)和癌胚抗原(CEA)的相关性研究。结果表明:(1)ER、PR水平与组织学分级呈负相关性。(2)低分化腺癌CEA阳性率最高,且淋巴结转移者CEA均为阳性,提示CEA与肿瘤的恶性度呈正相关。因此性激素受体和CEA提供了肿瘤组织不同的生物学信息,同时检测ER、PR及CEA水平对分泌治疗,手术范围及判断预后更有价值。     

电流变材料的设计、研制及其流变和应用性能研究

Electrorheological (ER) fluids, or suspensions, as one kind of smart materials, have very important and potential applications in electromechanical control due to their attractive features of rapid (with ms order), reversible, and controllable changes in rheological properties upon the application of an external electric field with kV/mm order[1～3]. Once ER fluids have met the engineering targets, they will bring revolution in several areas of industry and technology such as mechanics, trans portation, hydraulics and so on[4].     

Training Teachers for Extensive Reading Programmes

It has been suggested that the success of an ER project can largely rely on several elements, such as the selection of ap-propriate materials, establishment of management system, workshop for training ...     

“When We Make Mistakes,People Die!”: Constructions of Responsibility for Medical Errors in Televised Medical Dramas, 1994–2007

Despite the publicity of medical mistakes in recent years, most people vastly underestimate the frequency of errors, likely because media stories focus on flawed individuals, not institutional problems. This research examined contemporary medical dramas for constructions of responsibility in treating patients. Findings indicate that medical mistakes were rare in the storylines, meaning that health professionals were almost always depicted as behaving responsibly—to the extent that they were considered heroes. Mistakes were suggested to be due to the health professional's inexperience, institutional flaws that led to errors, and temporary personal problems. Health professionals were shown learning from their mistakes, suggesting that they would not be repeated. For committing mistakes, health professionals faced a range of consequences, depending on disclosure of the errors and whether patients had friends or families to push for restitution. Errors occurred throughout the years studied, but were greatest in the years when the dramas featured inexperienced medical students or residents as the main characters. Problems with the fictional health care system were largely ignored, suggesting one explanation for the focus on individual responsibility in real-life discourse.     

A BASIC MUSIC LIBRARY: ESSENTIAL SCORES AND SOUND RECORDINGS

SUMMARY

The electronic resources (ER) librarian has a social responsibility to be knowledgeable about the digital divide. Discourse on the digital divide began in the mid-1990s and continues today. Data analysis reveals that divides still exist, particularly when considering income, education, region, disability, age, and race. Librarians face many challenges to take on the digital divide. These challenges include issues of access, content, technical literacy, privacy, civic participation, education, employment, non-use, and political debate. Yet for each challenge, there is an opportunity for the ER librarians to thrive while they face down the digital divide.     

C-erbB-2、ER和PR在乳腺癌中的表达与预后意义

目的了解乳腺癌C-erbB-2、ER和PR的表达与预后的关系。方法应用免疫组化方法检测乳腺癌C-erbB-2、ER和PR蛋白表达。结果乳腺癌淋巴结转移组C-erbB-2的阳性表达高于未转移组,ER和PR的阳性表达低于未转移组;C-erbB-2阳性表达在I级、II级和III级之间呈明显上升趋势。结论ER、PR阴性病人伴随着较高的C-erbB-2阳性表达,在乳腺癌中预后较差
