马立克氏病病毒gB基因的克隆及重组鸡痘病毒的构建

通过PCR方法扩增了马立克氏病病毒 (MDV) 2 .8kbgB基因 ,并且在其两端加上PstⅠ和NotⅠ酶切位点。然后用PstⅠ /NotⅠ酶切回收 gB片段 ,插入到转移载体 pEFgpt12s复合启动子Spromoter的下游的PstⅠ /NotⅠ酶切位点处 ,构建了转移质粒pEFgpt12s gB。将该质粒与鸡痘病毒 (FPV)野毒 2 82E4株共转染鸡胚成纤维细胞 (CEF) ,通过MXHAT选择培养基进行筛选 ,蚀斑纯化 ,经PCR扩增证实重组病毒中含有 gB基因。重组病毒和FPV野毒在CEF上形成空斑大小无明显差别 ,病毒效价分别为 10 -5.43 TCID50 /mL和 10 -6TCID50 /mL ,表明外源基因的插入不影响所构建的重组病毒的生物学特性     

金水宝合拉米夫定治疗慢性乙型肝炎60例

目的：观察中药金水宝、水林佳合拉米夫定治疗慢性乙型病毒性肝炎的效果。方法：将89例慢性乙型肝炎患随机分成治疗组60例，对照组29例。疗程为9个月至2年。结果：治疗9个月后，治疗组在HBsAg、HBeAg、HBV-DNA阴转率，肝功能复常率及症状体征的恢复率方面优于对照组。结论：中西医结合治疗慢性乙型肝炎，能抑制病毒复制，改善肝脏循环和肝功能，提高疗效，缩短疗程。     

核因子-кB及其在创伤性脑损伤后的作用

核因子-кB是一种具有多向性调节作用的核转录因子。机体受到创伤后,NF-кB被激活,调节多种炎性介质基因转录,引起局部及全身的炎症反应。对NF-кB的有关研究可望用于法医学家对损伤时间的推测。     

信用证支付中基础合同的独立性探析

在信用证作为普遍支付方式的国际贸易过程中,基础合同是否独立于信用证一直是理论界和司法界颇具争议的问题.文章从理论基础和司法实践两方面对基础合同的独立性问题进行探讨,认为基础合同不能完全独立于信用证而存在,信用证的修改将对基础合同产生影响.在论证基础合同不完全独立于信用证的同时,分析了在信用证修改的情况下,基础合同的一方当事人还能不能以原合同中的权利救济条款向另一方主张权利的问题,并提出了处理具体案件所应遵循的规则.     

论我国信用证欺诈立法的缺陷与完善

我国有关信用证欺诈的立法在实体上存在着很大的模糊性和不确定性,在程序方面过于零散、不严密,这给司法实践带来了诸多不便。为了促进我国对外贸易的发展,有必要细化《刑法》关于信用证诈骗罪的规定,完善《民事诉讼法》关于诉讼保全的规定,制定系统的信用证欺诈法,并吸收国外一些成熟的立法和司法经验。     

Kenneth B. Clark and the problem of power

ABSTRACT

During the early 1960s African American psychologist Kenneth B. Clark, known primarily for his involvement in the 1954 Brown v. Board of Education US Supreme Court desegregation decision, began organizing an ambitious anti-poverty programme called Harlem Youth Opportunities Unlimited, Inc. (HARYOU). Dissatisfied by the lack of progress in school desegregation in New York City and discouraged by the inability of traditional social welfare organizations to address the problems of race and poverty, Clark argued that a new approach had to be developed to mobilize the black poor to gain the political and economic power that would solve their problems. At the same time, he theorized that a new form of racial segregation was beginning to develop in urban areas that foreshadowed increasing social isolation, economic dependence and declining municipal services for many African Americans. He called this new development ‘internal colonialism’ and hoped that HARYOU would be a demonstration project in the Kennedy–Johnson administration's War on Poverty that would address these problems from multiple perspectives. Nonetheless, the plan aroused the political opposition of Harlem Congressman Adam Clayton Powell. The dispute with Powell drove Clark from HARYOU and caused him to re-evaluate his thinking regarding African American leadership. He increasingly viewed the ‘ghetto’ as both a prison and a cocoon that satisfied white and black social, economic, political and psychological needs. By the end of his HARYOU experience, Clark coined the term ‘the new American dilemma’ to describe and theorize about an increasingly isolated and powerless black population in many urban centres. The term also signified his belief that the problem of power was intricately tied up in, while also separate from, the problem of race.     

Medical data breaches: Notification delayed is notification denied

The EU and the United States have implemented data breach notification rules that cover the health sectors. Nevertheless, data breach incidents involving medical data continue to rise, especially in the US and the UK. The HITECH Act, Pub. L. 111-5 Title XIII is the first federal health breach notification law in the US to be characterized by less government intrusions, while the revised EU Privacy Directive, 2009/136/EC calls for tougher privacy protection for data held by electronic communication providers. While the EU law sets a global de facto standard, the law remains toothless without strong enforcement mechanisms.     

Death Due to Complications of Anhidrotic Ectodermal Dysplasia

Ectodermal dysplasia comprises a group of disorders affecting ectodermal tissues. Severity depends on the genetic aberration; hyperpyrexia secondary to absence of sweat glands is a common complication. Treatment is supportive. This case report describes a 1‐month, 27‐day‐old male infant with a diagnosis of X‐linked recessive anhidrotic ectodermal dysplasia. On the day of his death, his mother swaddled him in a blanket and placed him on the couch at 5:30 am. When she picked him up at 8:00 am, he was unresponsive. At the emergency department, his rectal temperature was 40°C. Postmortem blood culture was positive for group B streptococcus, a possible etiology for fever. It is vital to teach parents that close monitoring of children with ectodermal dysplasia is necessary, as an increase in body temperature can become life threatening.     

内蒙古中西部地区汉族、蒙古族ApoB基因遗传多态性

目的研究内蒙古中西部地区汉族、蒙古族ApoB基因遗传多态性。方法选取内蒙古中西部地区汉族、蒙古族无关个体,采用聚合酶链反应一限制性片段长度多态性技术,判断样本中是否含有ApoB基因中的稀有等位基因：XbaI（x＋）和＆DRI（E-）,并计算其基因型频率、等位基因频率及相关的群体遗传学参数。结果内蒙古汉族群体中稀有等位基因XbaI（x＋）和＆0RI（E-）频率分别为2％和4．6％,而在蒙古族群体中没有检测出此两种稀有等位基因。结论ApoB基因XbaI和＆0RI位点的等位基因频率分布在不同种族中差异较大,具有种族鉴定的应用可能。
