西医教育模式对中医基础学科体系形成的影响及反思 总被引:4,自引:0,他引:4
近代中医学界为争取中医教育加入学校系统,仿照西医学科体系框架设置中医课程;为沟通中西医,适应时代潮流,以西医为参照系整理构建出中医基础学科体系的雏形;中医高等教育承袭了近代中医教育的模式及课程体系,是造成中医后继乏人、乏术的重要原因. 相似文献

诱导排卵联合宫腔内人工授精是广泛应用的一项辅助生育技术。诱导排卵目的是形成单一卵泡的发育成熟,尽可能地减少发生多胎妊娠和卵巢过度刺激综合征的风险。抗雌激素类和芳香化酶抑制剂因口服方便而广泛应用,单独使用妊娠率较低。促性腺激素类药物可以获得较高的临床妊娠率,采用小剂量递增的温和方案不但能够保证较高的单卵泡发育还能够明显的减少并发症的发生。关于促性腺激素促排卵治疗中卵巢反应预测因子还有待于进一步研究。 相似文献

Auditory brainstem responses (ABRs) to click stimuli have become established as a useful indicator of hearing thresholds in infants and young children. Although the investigation is objective in so far as the patient is concerned, a subjective element remains in the decision by the operator as to whether or not an ABR is present in an averaged waveform. A simple on-line computer detection technique is described which removes some of the reliance placed upon the operator. The technique employs a scanning window for correlation and amplitude analysis of pairs of averaged ABR waveforms.The reliability and accuracy of computer and operator scoring of 25 thresholds in normally hearing adults and 50 thresholds in infants and young children with suspected hearing impairment have been investigated. In the adult group, 96% of computer estimates of the threshold were within ± 10 dB of the subjective hearing threshold, compared with 92% for operator scoring. There were 92% of computer and operator scores within ± 10 dB of each other. In the patient group there was equally good agreement between computer and operator scoring with 90% of the thresholds within ± 10 dB of each other; the incidence of possible false-positive thresholds was also lower with computer scoring.This on-line scoring technique, therefore, offers useful assistance to the operator; requires only limited computing power, and is suitable for use in a routine clinical environment. 相似文献

Background:Hemifacial spasm (HFS) is a clinical common neurological disease, its main performance for 1 side or 2 sides muscles (the orbicularis oculi muscle, expression, orbicularisoris muscles) recurrent paroxysmal, involuntary twitching, aggravating when excited or nervous, more severe cases of the disease may include difficulty in opening the eyes, crooked corners of the mouth, and twitching noises in the ears, etc.[1] Early manifestations of the disease are intermittent mild convulsions of the orbicularis oculi muscle, and then gradually spread to 1 side of the facial muscles, such as frowning muscles, nasal muscles, buccinalis muscles, etc, especially the most obvious spasms of the oral muscles, which can involve the ipsilateral platysma muscle in severe cases, with each twitch for a few seconds to a few minutes. The disease will affect the quality of life such as speaking, eating, seeing and so on, and even cause psychological effects such as inferiority, anxiety and depression. At present, the incidence of the disease in China is 11 per 1.1 million, females are more common than males. There are many ways to treat HFS, but the Qianzheng powder has a unique advantage in treating this disease. Therefore, our systematic review aims to evaluate the efficacy and safety of Qianzheng powder in the treatment of Primary Hemifacial spasm, and to provide a reliable basis for clinical decision makers.Methods:From its inception until April 2021, we will search electronic databases, including PubMed, Embase, Cochrane Library, China Biomedical Literature Database, China Knowledge Infrastructure, Wanfang Database, and China Scientific Journals Database. The authors will independently sift through studies, extract data information, and assess methodological quality using the Cochrane Risk of Bias tool. The RevManV. 5.3 software will be used for statistical analysis.Results:The results of this study, which will be published in a peerreviewed journal, will evaluate the efficacy and safety of Qianzheng powder in the treatment of primary Hemifacial spasm.Conclusion:This systematic review will provide reliable evidence-based basis for treating primary Hemifacial spasm with Qianzheng powder.INPLASY Registration number:INPLASY202130037. 相似文献

随着近年来社会经济与医疗器械水平的发展,人们对健康的要求已经不仅是局限于以往的"不生病",而是转而追求更高程度的健康水平。因此,我国相关教育部门开始注重护理教育的时代性改革,并将工作重心由治病转移一部分到护理工作上来,加强护理人员的专业素质培养,促进全面健康社会战略目标的早日实现。由此可知,优化改革护理教育工作是促进护理工作改革的重中之重,也是当前教育部门针对护理教育进行有效改革的具体落实点。本文主要结合当前时代特点对我国护理教育的发展状况进行分析与探讨,总结出教育过程中存在的问题与不足,并就其提出针对性建议,旨在推动当前护理水平的提升,促进护理行业能够更好的满足人民群众的健康需求,以此推进我国护理事业的发展。 相似文献
