当代科技的进步和社会经济的发展,对中职教学提出了新的要求:培养全面发展,特别是善于自学、创新、具有自强精神和主体人格的“四有”人才。同时在我国护理专业的教学中,已形成了本科、高职、中职等多种层次的教学。如何适应当前分层次的护理教学,对于中职护理专业的课程提出了更高的要求。因此,对课程的教改已势在必行。 相似文献

医学院校外语教学观念的转变 总被引:1,自引:1,他引:0
近年来,随着世界信息网络一体化发展和国际学术交流的日益频繁,如何培养具有较高外语水平的高素质医学人才,对医学院校外语教学提出了新的要求。外语教学所面临的诸如费时低效、高分低能、聋哑英语等问题和弊端日益突出,这一系列问题的实质就是“学”与“用”的脱节。因此,更新医学院校外语教学观念,调整外语教学思路,成为当务之急。而外语教学 相似文献

Eighteen families in which both parents had refractions within the range of +4·0 D to −4·0 D and axial lengths seen in emmetropia (22·3-26·0 mm) showed coefficients of correlation of the order 0·5 indicative of polygenic inheritance. Such coefficients were seen for axial length (0·407) and for the cornea (0·487), but not for the lens (which is known to be yoked to the axial length). No such coefficients were seen in 19 families in which one of the parents had axial length outside the emmetropic range (nine families with long axes and 10 with short axes).
The pattern of polygenic inheritance for emmetropia (completely correlated optical components) and errors of refraction up to 4·0 D (inadequately correlated components: correlation ametropia) follows that seen in stature and other measurable characters. In contrast the high refractive errors with their abnormal axial lengths (component ametropia) are—like the extremes in stature—pathological anomalies with monofactorial inheritance.

A further analysis of already published data supports the position that retardates of low ability level less frequently have retarded siblings, retarded parents, and parents low in occupational level than do retardates higher in ability level. The analysis supports the position that there are two types of retarded individuals, persons retarded as a result of gene or chromosomal anomalies, brain injury, etc., who more frequently occur in the lower-level retardate group, and persons whose retardation represents polygenic segregation, who more frequently occur in the higher-level group. 相似文献

背景:局部注射具有成骨作用的辛伐他汀,可显著增加骨质疏松大鼠股骨颈及股骨髁部的骨密度及力学强度,分析局部注射辛伐他汀对股骨髁骨小梁的影响。
目的:进一步研究骨质疏松大鼠股骨内局部注射辛伐他汀对股骨髁骨小梁的影响。为将辛伐他汀应用于临床骨质疏松局部治疗提供实验基础。
方法:18只雌性SD大鼠双侧卵巢切除后3个月,制备大鼠骨质疏松模型。实验大鼠随机数字表法均分为3组,分别在实验大鼠的右侧股骨髓腔内单次注射辛伐他汀溶液5 mg、10 mg,对照组单纯注射空白载体。分别在注射后1个月处死大鼠并取材。Micro-CT扫描并定量分析骨组织形态变化。
结果与结论:给药后1个月,Micro-CT扫描结果显示,辛伐他汀治疗组的骨微结构参数如骨皮质厚度、骨小梁密度及连接率明显优于对照组。说明疏松骨骼单次注射小剂量辛伐他汀可显著促进股骨髁部骨小梁改建,改善骨骼微结构,可为强化局部、防治骨质疏松骨折的新选择进一步提供实验基础。 相似文献

This paper describes the rationale and different approaches for developing islets of Langerhans xenotransplantation. Implementing this therapeutic strategy in the treatment of human diabetes mellitus requires careful consideration of its potential risks and benefits, taking into account the current status of the treatment of this disease. 相似文献
