C-反应蛋白在急性脑梗死中的意义

目的 观察急性脑梗死患者的血清C-反应蛋白(CRP)水平，探讨其在脑梗死中意义。方法 分急性脑梗死患者为大面积、小面积及腔隙性梗死组，并设健康对照组，观察上述组别CRP水平。结果 急性脑梗死患者较健康对照组CRP值显著升高，而且在不同组别的急性脑梗死患者中，CRP值随梗死面积增大而升高，两者呈正相关。结论 急性脑梗死患者血CRP水平升高。CRP升高，可损伤脑组织。血CRP水平，可作为脑梗死患者病情轻重、转归、预后的预测因子。     

Educating early childhood teachers for the global world

Teachers for the twenty-first century for the global world need to be proficient in technology and skilled as reflective practitioners. They need to be able to reflect on diversity in myriad ways: learning styles, special needs, cultural differences, racial differences, developmentally appropriate differences, teaching styles and personality differences of children, teachers, parents, community members and administrators. The paradigni shift of the twenty-first century is that teachers need to be team players who are skilled at operating in a variety of collaborative partnerships.

The Early Childhood Program Faculty, at NEIU, with the help of a Teacher Quality Education grant, developed with six universities in Illinois called Illinois Professionals Learning Partnerships (IPLP), set out to adapt the NEIU/ECED program for the twenty-first century in a global world by focusing on four goals: (1) increasing technology and writing skills across the curriculum, (2) developing reflective skills and understanding of diversity (special needs, multicultural/international cultures), (3) developing student experience working in collaborative partnerships and (4) increasing clinical experiences.

The IPLP grant enabled the ECED program to: (1) spend intensive time on changing the curriculum in two retreats a year, (2) develop a faculty cohort including tenure track faculty, visiting lecturers and adjuncts, (3) develop a combined program of research and program development, (4) recruit and hire three new tenure track international faculty, (5) develop professional development schools and intensive field experiences, (6) combine resources for many grants, (7) develop short-term international experiences and faculty exchange programs and (8) increase technology skills of students and faculty through action laboratories on using video technology, digital cameras, reflective email discussions and videography.     

Preservice early childhood students' perceptions of written feedback on their essays

Lecturer feedback on students' essays is important to the quality of the experience students have at university (Norton & Norton, 2001). The aim of the present study was to investigate whether early childhood students at one university actually read lecturer feedback on their essays and, if they did, what they found helpful and not helpful to their learning. Feedback was defined as 'giving students information on how well or how poorly they are doing in their academic work' (Hounsell, 1987, p. 109). Using the Vygotskian concept of learning as a socially shared activity, qualitative data were collected from second-year students from a four-year early childhood degree programme via an anonymous survey and four focus groups. Major findings were that, in contrast with studies of students in other programmes, early childhood students read lecturer feedback on their essays and used feedback that was detailed and explanatory as a learning tool. Types of feedback students found to be most and least useful were identified.

低分子肝素用于急性心肌梗死溶栓后辅助治疗的临床观察

目的 :探讨低分子肝素用于急性心肌梗死溶栓后辅助治疗的疗效与安全性。方法 :6 4例急性心肌梗死患者采用尿激酶溶栓再通后随机分为肝素组 (肝素钙 75 0 0U皮下注射 ,每日 2次 )和低分子肝素组 (低分子肝素 0 .1mL/kg皮下注射 ,每日 2次 ) ,连续 7d。结果 :治疗后两组心肌再梗死、梗死后心绞痛、血管性死亡及出血肝素组均显著高于低分子肝素组 (P <0 .0 5 )。结论 :急性心肌梗死溶栓后使用低分子肝素代替普通肝素作为抗凝剂是安全有效的。     

54例SARS患者胸部影像学表现分析

目的：探讨SARS的影像学表现、分型与诊断。方法：54例临床诊断的SARS患者均有系列胸片，23例有CT资料，进行回顾分析。胸片分型为：单纯型(Ⅰ)、进展型(Ⅱ)、迁延型(Ⅲ)。对18例临床治愈出院后胸片、CT复查结果进行对比分析。结果：54例中，15例以肺实质渗出、实变为主，5例以肺问质浸润为主，34例兼有肺实质、间质病变。Ⅰ型(n=12)胸片表现多不具特征性，预后好；Ⅱ型(n=25)胸片表现具有相对特征性，病死率高(16％)；Ⅲ型(n=17)残留病变最多(100％)。CT显示残留病变比胸片更清楚。结论：SARS影像学表现仅具有相对特征性，诊断必须结合临床、流行病学和实验室检查。
