阿尔茨海默病为世界范围内的痴呆常见类型,是目前全球关注的健康热点问题。针对β-淀粉样蛋白(Aβ)沉积和过度磷酸化tau蛋白聚集的内在生物化学机制已有深入研究,来源于正常可溶性Aβ肽的Aβ寡聚体被认为最具毒性。然而,纤维状Aβ聚集形成淀粉样斑块和淀粉样脑血管病是阿尔茨海默病的主要病理改变;而异常磷酸化tau蛋白沉积并形成可溶性毒性寡聚体,进而聚集成为神经原纤维缠结,则是其另一重要病理特征。目前,已有许多措施用于抑制、清除或减缓阿尔茨海默病淀粉样斑块的病理进程,而免疫治疗是这一领域中的新的突破。针对Aβ沉积阿尔茨海默病动物模型进行的主动和被动免疫治疗,已取得重大研究成果。然而,临床试验仅有极少数据显示出明确的疗效,究其原因在于免疫治疗引起的并发症。主动免疫实验引起的脑炎,以及被动免疫治疗在少数人群中诱发的血管源性水肿或淀粉样蛋白相关显像异常已有相关报道。迄今为止,单纯针对tau蛋白聚集的治疗仍然仅局限于小鼠模型,鲜有研究同时针对Aβ沉积和tau蛋白聚集两种病理特征。到目前为止,大部分免疫治疗均以自身蛋白为靶向,尽管其构造异常,在取得疗效的同时,需防止引起过度毒性炎症反应的可能。为取得更好的疗效,未来的免疫治疗应集中在毒性寡聚体,并以阿尔茨海默病的所有病理特征为靶向。

中国和美国护理人员数量分别居于世界第一和第二位,两个国家均实行了护士执业资格考试以确保注册护士资格的标准化。1995年,中国建立了全国护士执业资格考试制度。与美国相类似,中国护士执业资格考试成为护士注册程序中的重要纽带,对于保障护理工作质量、促进护理行业发展做出了重要贡献。未来中国可能需要借鉴美国相关经验,以不断完善护士执业资格考试制度,比如提高考试频率、为考生提供个性化服务、继续改革考试内容与方式等。如果考试内容和方式能够更好地与当前护理范式及临床要求保持一致,将有利于护士们在进人卫生服务领域时更好地完成护理患者的准备。由于拥有数量巨大的护理队伍,中美两国在护士执业资格考试方面的实践与经验对于其他发展中国家具有一定的示范作用。在中国进一步推动护理教育标准化的新政策成形之际,护士执业资格考试制度改革应该与课程体系改革同步推行。与此同时,课程体系与护土执业资格考试改革对于中国护理队伍建设与护理服务质量的影响需要进一步进行研究。

Objective: The aim of our study was to compare the results of tubularized plate urethroplasty with interposing healthy tissue spongioplasty alone and spongioplasty with dorsal dartos flap to assess the role of dartos flap in prevention of fistulae. Patients and Methods: A retrospective study was performed on 80 patients, aged 4 months to 27 years who underwent hypospadias repair using the Snodgrass technique. The patients were assigned to two groups. In group I (40 patients) the neourethra was covered with spongioplasty only, and in group II (40 patients) the neourethra was covered with spongioplasty plus dartos flap. Integrity of the urethral plate was maintained in all the cases. The ventral curvature & torsion was corrected by penile de-gloving, mobilization of the urethral plate and spongiosum and mobilization of the proximal urethra if needed. The results were analysed in view of complication rates. The average period of hospital stay was 7 days & follow-up varied from 8 months to 28 months with a mean of 14 months. Results: In group I, hypospadias were distal penile in 31 (77.5%), mid-penile in 4 (10%) and proximal/peno-scrotal in 5 (12.5%) patients. In group II, hypospadias were distal penile in 17 (42.5%), mid penile in 9 (22.5%) and proximal/peno-scrotal in 14 (35%) patients. Sixty five percent in group I and 80% in group II had ventral curvature but the difference was not statistically significant. Good functional results were achieved in 97.5% patients in group I and in 95% patients in group II?which were statistically similar (p value—0.585). Urethral fistula was encountered in 2.5% in group I & in 2 cases (5%) in group II. Meatal stenosis was noted in 7.5% each in both groups, which responded to urethral dilatation. One patient in group II had complete disruption.?There was no statistically significant difference in early and late complications in both groups (p value—0.812). Conclusions:?Spongioplasty with healthy spongiosal tissue is strong enough and
