在实践中"嫁接"新课程 总被引：1，自引：0，他引：1
在新旧课程的转变中,鉴于实践过程操作性难度较大的问题,本文从课程的功能、结构、内容、实施、评价和管理等六个维度,对传统基础教育课程进行批判继承,对新课程实施进行思考,试图探求一条新旧课程嫁接和生成的有效途径,确保新课程改革实施的可行性与现实性,提高新课改实施的质量。 相似文献

Coronary artery bypass grafting surgery is increasingly being carried out on patients with multi-vessel coronary artery disease,
but the best grafting candidate for non-left anterior descending coronary arteries is unclear. This research sought to systematically
compare the efficacies and safeties of coronary bypass with radial artery and other available grafts. A systematic literature
retrieval was performed for all clinical trials comparing the outcomes of coronary artery bypass surgery with radial artery
and other grafts in PubMed, EMBASE, and the Cochrane Library. Seven eligible clinical studies, comparing radial artery and
great saphenous vein grafts, were found between 1966 and 2010: one prospective non-randomized and six prospective randomized
trials. The pooling analysis obtained a relative risk of 0.507 (P<0.05) of graft occlusion in radial arteries compared with great saphenous veins. There was a significantly lower infection
rate in arms (i.e., harvest sites for radial arteries) relative to legs (harvest sites for veins), with a pooled relative
risk of 0.140 (P<0.05). From the reports on mortality after follow-up ranging from one year to six years, there was no significant difference
in mortality between the two graft types (P=0.927). In addition, four cohort controlled trials for radial and right internal thoracic artery grafts were included. The
radial graft was associated with less cardiac related events relative to the right internal thoracic artery graft (P=0.014), but with comparable mortality and comparable rates of repeat percutaneous transluminal coronary angioplasty. Subjects
with radial arteries seemed to have a lower occlusion rate and a lower graft harvest site infection rate than those with great
saphenous veins. Moreover there were fewer cardiac related events with radial arteries relative to the right internal thoracic
artery grafts. More studies are needed to confirm these findings concerning the favorable outcomes of coronary artery bypass
grafting with radial arteries on long-term patency and mortality. 相似文献

目的研究三明治法Onlay植骨结合GBR技术应用于上颌骨洞穿性骨缺损后牙槽嵴水平向及垂直向骨量的变化;评价该项技术在口腔种植中的应用效果。方法抽取泰州市中医院近年的5名病例作为研究对象,通过口腔专科检查和口腔颌面CT检查进行术前评估,通过Onlay植骨结合GBR技术修复骨缺损区,恢复缺牙区的骨量和缺失牙,手术后8个月通过CT检查,评估骨增量效果,并行种植修复。结果植骨术后8个月,患者缺牙区牙槽嵴水平骨量提升4.2mm,垂直骨量提升18mm,患者口腔软组织、牙龈颜色、牙龈乳头均基本恢复正常,供骨区无神经症状、继发性感染及其他不适。种植体骨结合良好,稳定性佳,患者对修复效果满意。种植牙留存率100%。结论三明治法Onlay自体骨移植结合GBR技术是解决上颌骨洞穿性骨缺损的有效临床途径,能够使牙槽骨水平向及垂直向骨量均得到良好改善,为后期的种植修复提供良好的骨基础。 相似文献

文化旅游是当今旅游业的发展趋势,人们对于文化旅游资源的发掘多有著述,而对发展文化旅游的具体方式和方法则少有关注。郴州是全国旅游城市,因地处偏远而积存了许多较为古老的文化旅游资源,又因位于湘、粤、赣三地交界处,因此其历史文化具有边缘性的特征。发展郴州的文化旅游业,应立足本土文化,坚持求异导向,做好以下三个方面的工作:从当地的文脉中提取有差异性的主题以进行形象定位;在打造旅游产品时对文化事象施以巧妙的嫁接;塑造具有本土文化特色的旅游接待风格。 相似文献

目的:探讨片状增生性瘢痕外科手术治疗的方法及疗效。方法:对76例片状增生性瘢痕采用随机分组进行增生性瘢痕切除并刃厚皮片移植术;增生性瘢痕切除、瘢痕上皮回植术两种手术方法比较性研究。结果:两种方法在疗效上无显著差异(P>0.05),但手术野数目和住院时间存在显著差异(P<0.05)。结论:片状增生性瘢痕可以采用瘢痕切除、刃厚皮片移植或瘢痕上皮回植术治疗,瘢痕上皮回植术优于刃厚皮片移植术。 相似文献
