Ben L. Reitman,MD: colorful critical criminologist

Ben Reitman, a medical doctor, fought throughout his life for greater sympathetic understanding of and assistance to American’s underdogs. He spent his early years living among social outcasts and riding the rails with hobos. He then teamed up with Emma Goldman to advance her political agenda of anarchist ideas and in support of free speech. After an amiable split with Goldman, he worked in Chicago, treating prostitutes, performing illegal abortions, combating venereal disease, and battling to make birth control information freely available. Reitman also associated with several of the prominent members of the University of Chicago’s stellar sociology faculty and contributed importantly to their studies of urban life.     

Admitting a Bad Influence: Contracting the Public Service

Abstract

Emulation of the private sector is a longstanding controversy in public administration, but could it constitute a bad influence, of the kind that parents seek to guard against by scrutinizing their children's peers? Effectiveness provides a perspective on how helpful or harmful private sector influence has been for the public service. The practice of contracting-out under the A-76 process receives particular scrutiny relative to maintaining the effectiveness of public agencies. A second perspective on private sector influence examines, through the theoretical perspective of transaction-cost economics, the promise of cost savings that justified recent acceleration of contracting-out. The author, himself a government contractor, also bases his analysis on personal experience.     

我国工伤保险程序存在的问题及完善

工伤保险自诞生以来就具有强大的影响力,原因之一在于其程序简便易行。然而在我国,劳动者申请工伤保险待遇却要历经多重程序,耗时之长、过程之艰难已经成为工伤保险制度优越性发挥的障碍,为此,应以法律人本主义理念改革我国的工伤保险程序。

猪水泡病病毒结构蛋白编码区核苷酸的序列测定与分析

以猪水泡病病毒 (Swinevesiculardiseasevirus ,SVDV)HK’70为材料 ,用特异性引物扩增出P1区的 2个重叠目的片段 ,连接于pMD 18 T载体 ,转化JM 10 9感受态细胞。经重组质粒的双酶切 ,PCR鉴定后测序。序列分析表明 ,HK’70P1区核苷酸组成中A含量较高 ,G C含量较低 ,且A G、C T转换率较高。P1序列同源性分析表明 ,SVDVHK’70与J1’73、H/3’76、SVDV(Seechurn等测株 )、NET/1/92的核苷酸序列同源性分别为 97.8%、98.1%、97.6 %和 89.3% ;相应地 ,推导的氨基酸序列同源性分别为 98.8%、98.7%、98.8%和 96 .5 %。     

传染性腔上囊病病毒HN01超强毒株VP2基因的克隆和序列分析

根据GenBank中登录的传染性腔上囊病病毒(IBDV)标准强毒株52-70株基因组序列,设计并合成了1对扩增IBDV VP2基因的特异性引物.以IBDV超强毒分离株HN01感染发病鸡腔上囊组织中提取的病毒RNA为模板,用RT-PCR扩增出了1.45 kb的cDNA产物,将扩增的IBDV HN01株VP2基因克隆于pMD 18-T载体上,获得了pMD 18-T-VP2重组质粒.将IBDV HN01株 VP2基因序列测定结果与已发表的其他IBDV毒株VP2基因序列进行分析比较,绘出系统进化树.结果表明,HN01株与欧洲超强毒株UK661、日本超强毒株OKYM、香港超强毒株HK46等非常相似,而与经典强毒株、弱毒株和变异株相差较大.     

金龙蛤蚧平喘胶囊治疗稳定期慢性阻塞性肺疾病临床观察

目的 观察金龙蛤蚧平喘胶囊治疗稳定期慢性阻塞性肺疾病（chronic obstructive pulmonary disease,COPD）的疗效。方法 将58例COPD患者随机分为治疗组和对照组,每组28例。在常规治疗基础上,分别给予金龙蛤蚧平喘胶囊与安慰剂。治疗前、治疗6个月后和治疗12个月后,分别观察两组患者的肺功能、骨密度（bone mineral density,BMD）、BODE指数、COPD评估测试（COPD assessment test,CAT）问卷评分及1年内急性加重次数。结果 治疗6个月后及治疗12个月后,两组肺功能各项参数比较,差异均无统计学意义（P＞0.05）。 治疗12个月后,治疗组股骨颈BMD较治疗前显著升高（P＜0.05）,而对照组股骨颈BMD较治疗前显著下降（P＜0.05）。治疗6个月后和治疗12个月后,两组BODE指数及其因子6 min步行距离积分比较,差异均有统计学意义（P＜0.05）。两组1年内急性加重次数相比,差异具有统计学意义（P＜0.05）。结论 金龙蛤蚧平喘胶囊可有效改善稳定期COPD患者的肺功能、BODE指数及生活质量,减少患者1年内急性加重次数。     

糖尿病肾病血瘀证大鼠铁死亡相关基因GPX4、ACSL4表达水平变化
