The current situation in which the humanities are disparaged affects all university disciplines, including nursing, in whose historical evolution the humanities have always been present in one form or another. Looking beyond this disrepute, this study proposes that nursing renew its attention to classical philosophy. Specifically, it invites a close reading of Xenophon's Anabasis and Plato's Meno, to get three related goals: to show how the use of ancient texts are very valuable tools for the philosophical initiation of nursing students and can help them reflect on their choice of nursing as a practical activity; to reflect on the problem of virtue and the nature of the good life; and to show how the interaction with ancient texts allows students to reflect on questions and issues of life, theirs and others, that are not open to investigation through a purely scientific method. Consequently, both Anabasis and Meno readings strengthen the intellectual relationship between philosophy and nursing, enabling the latter to delve deeper into the key questions of its own thought as a discipline. 相似文献

Since the new round of health care reform in 2009, the vertical integration of hospitals and primary health institutions has become widely implemented in China as an efficient method for improving quality of primary care. This study aimed to answer the following questions: (a) What is the perceived quality of township health centres (THCs) under integration? (B) What differences could be observed among the three typical integration models, namely, private hospital-THC integration, public hospital-THC integration, and loose collaboration? Two rounds of cross-sectional surveys were conducted from November 2016 to June 2018. The Chinese version of the Primary Care Assessment Tool was used to evaluate perceived quality of sample THCs, and 1118 adult patients were interviewed in total. Multiple linear regressions were employed to compare the quality scores between two survey rounds and among different integration models after controlling for potential confounders. The results revealed that the quality of care significantly improved under private hospital-THC integration as observed by comparing two survey rounds, while no change or slight changes were observed in the other two models. The difference observed among the three models was that the perceived quality of THCs integrated with private hospitals was worse than that of THCs integrated with public hospitals and THCs under loose collaboration, while no significant difference was observed between public hospital-THC integration and loose collaboration. Increased attention should be given to highlighting the tight integration between hospitals and THCs and the different roles played by private and public hospitals in the current reform. 相似文献

目的 比较1.8 mm同轴微切口超声乳化术与传统同轴3.0 mm小切口超声乳化术的临床疗效及术后并发症。方法 收集2015年5月至10月北京同仁医院北京同仁眼科中心收治的老年性白内障患者48例(48眼),将患者分为微切口组和小切口组。微切口组主切口长1.8 mm,前房内注入透明质酸钠,行直径约为5.0 mm的中央连续环形撕囊,水分离后用劈核钩劈核,扭动模式超声乳化吸出术,自动灌注系统吸出残留皮质。小切口组角膜主切口大小为3.0 mm,术中植入常规折叠式人工晶状体。术后行裂隙灯、眼底镜以及角膜地形图检查,电脑验光检查患者最佳矫正视力。结果 术后1周、1个月、3个月两组患者最佳矫正视力比较,差异均无统计学意义(均为P>0.05)。术后1个月和3个月两组间手术源性散光比较,微切口组均明显低于小切口组,差异均有统计学意义(均为P<0.01)。在微切口组组内术后1个月和3个月手术源性散光无明显差异(P>0.05),微切口组手术源性散光在术后1个月保持稳定。在小切口组组内术后3个月手术源性散光明显低于术后1个月 (P<0.01)。微切口组术前角膜厚度为(567±27)μm,小切口组为(564±25)μm,两组差异无统计学意义(P>0.05);术后1个月与3个月两组间角膜厚度变化差异亦均无统计学意义(均为P>0.05)。在随访期间两组患者均未发生后发性白内障。结论 1.8 mm同轴微切口白内障超声乳化吸出术安全可靠,术后散光恢复快,可有效减少术后角膜手术源性散光。 相似文献
