目的:回顾性分析心脏疾病患者血清中B型钠尿肽(B-type natriuretic peptide,BNP)的水平,探讨对该类疾病检测BNP浓度的临床诊断意义.方法:汇总弋矶山医院2007年至2013年988例患者血清BNP浓度测定的结果,根据临床诊断筛选321例心脏疾病患者数据,按性别、年龄、科室及血清BNP浓度值等进行分析.结果:经统计学处理,患者血清BNP的水平与年龄之间未见正相关系,BNP浓度差异与性别之间也未见显著相关性,BNP浓度区间以48.9ng/L、266.4ng/L、1526.0ng/L三截点最为集中.结论:血浆中BNP的浓度与年龄和性别间的相关性未能体现,但BNP的测定的确是临床科室评估心功能的快捷手段,也是应用于心力衰竭的诊断、预后和判断的重要补充. 相似文献

实验选择12头、2-3岁、体重300-500kg雄性去势水牛,经粪便检查和DotELISA检查肝片吸虫阴性,随机分成感染组(n=9)和对照组(n=3),感染组每头一次口服1600个囊蚴.每周定时分别从水牛颈静脉采集感染前0周和感染后25周血液一次,分离血清,测定血清中的钾、钙、钠、镁、磷、氯等无机盐的含量,旨在研究感染肝片吸虫对水牛机体无机盐含量的影响.结果表明感染后水牛血清中的钾、钠、钙、镁、磷、氯的含量均成波状线变化,说明肝片吸虫感染后机体无机盐含量发生了不同程度的变化,这与虫体感染后机体的代谢发生改变有关. 相似文献

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help? 相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love. 相似文献

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject. 相似文献

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities. 相似文献

During interview with English majors, it was found that a majority of students expressed disappointment with their experience of English literature classes. Students' dislike of learning English literature appears to be the major problem of teaching English literature in China. Reader response approach is a good way to solve this problem. In this paper, I explain the rationale behind the reader response approach, such as its origin, definition, features, assumptions, and strategies. Then I illustrate how reader response approach works as a teaching strategy by presenting several teaching models. At last I evaluate its usefuiness for teachers and present the advantages of reader response approach in Chinese context. 相似文献
