在股骨颈移位骨折的治疗中,试用了7种不同的闭合复位方法。其中Whitman's法在骨折床台上进行,正常肢体外展,患肢由屈曲牵引至完全伸直位后,维持牵引并外展到与对侧肢体相称位,单髋人字石膏外固定(1914年)。 Leadbetter's法也在骨折床台上进行。将患肢髋部屈曲90°,沿大腿轴线行手法牵引。同时股骨干稍内收,患肢缓慢行环形活动至外展、内旋位,患肢向下降至骨折床台面时,行跟掌试验以验证是否完全复位(1933年)。 Bozan's法利用骨折床台使双下肢维持在伸直位,大绷带放置在患肢髂嵴部位,小绷带放置在患肢腹股沟皱襞最高点处实施牵引。然后整个患肢极度内旋,在维持侧方牵引的同时,患肢外展并轻度过牵(1934年)。 相似文献

自杀基因联合中医药疗法治疗肿瘤的设想 总被引:8,自引:1,他引:7
自杀基因疗法是一种具有良好应用前景的肿瘤治疗新措施。但如何有效提高疗效是目前仍须解决的关键性问题。由于免疫机制在自杀基因疗法旁杀伤效应中的重要作用,激活荷瘤机体的免疫功能,改善自杀基因抗肿瘤作用的炎症免疫微环境,是提高肿瘤自杀基因疗法疗效的主要策略。中医中药在调节机体免疫状态方面具有肯定的作用,与其他方法比较具有明显优势。因而,将自杀基因疗法与中医中药联合应用,有可能起到提高肿瘤自杀基因疗法疗效,防止肿瘤复发的作用。提出了自杀基因联合中医药疗法治疗肿瘤的新设想,为肿瘤基因治疗提供了一种新的思路和模式。 相似文献

穴位敷贴对哮喘豚鼠引喘潜伏期及肺组织病理变化的影响 总被引:5,自引:1,他引:4
【目的】从微观病理探讨穴位敷贴治疗哮喘的机制。【方法】采用随机对照的研究方案 ,以自制敷贴方敷贴实验性哮喘模型颈背“穴位”。敷贴方由麻黄、细辛、甘遂、延胡、附片、防风、五味子、白芥子组成。【结果】从第 6天开始 ,贴药组点头呼吸的潜伏时间明显延长 ,与哮喘组比较差异有显著性 (P <0 .0 5) ;从第 9天始穴位敷贴组豚鼠发生点头呼吸的频度明显减少 ,与哮喘组比较差异有显著性 (P <0 .0 1) ;且贴药组有降低豚鼠炎性渗出及嗜酸性粒细胞数的作用 (与哮喘组比均P <0 .0 5)。【结论】提示穴位敷贴治疗哮喘可能是通过延长哮喘发作的潜伏期 ,减小哮喘发作的频度 ,减少肺组织水肿、渗出 ,降低嗜酸性粒细胞的肺系局部浸润而实现的。 相似文献

HNE1细胞株光动力学治疗前后形态学的动态变化 总被引:8,自引:2,他引:6
目的 探讨体外光动力学治疗(PDT)引起鼻咽癌(NPC)细胞死亡的作用机制。方法对鼻咽癌细胞株HNE1体外光动力学治疗前后形态学变化进行动态观察。结果 对照组HNE1细胞培养3h,6h,12h,24h和48h后细胞形态与正常培养组HNE1细包开始变形皱缩,细胞界限模糊,细胞透光度和立体感较差,治疗24~48h后细胞发生凋亡。结论 体外光动力学治疗对HNE1具有明显的杀伤效应并HNE1细胞凋亡。PD 相似文献

穴位注射加贴敷治疗乳腺增生的临床研究 总被引:11,自引:0,他引:11
97例患者随机分为穴位注射组 (31例 )、穴位贴敷组 (35例 )、穴位注射加贴敷组 (31例 )进行临床观察。结果穴位注射组与穴位贴敷组疗效相似 (P>0 .0 5 ) ,而穴位注射加贴敷组疗效明显优于单纯穴位注射组及穴位贴敷组 (P<0 .0 5 )。由此说明 ,穴位注射加贴敷这一综合疗法治疗乳腺增生病具有效佳、副作用小、取穴少、疗程短等优点。此外还证实这一疗法对卵巢激素有一定的影响。 相似文献

Metal stents and, more recently, polymer-coated metal stents are used to stabilize dissections, eliminate vessel recoil, and guide remodeling after balloon angioplasty and other treatments for arterial disease. Bioresorbable polymeric stents are being developed to improve the biocompatibility and the drug reservoir capacity of metal stents, and to offer a transient alternative to the permanent metallic stent implant. Following a brief review of metal stent technology, the emerging class of expandable, bioresorbable polymeric stents is described, with emphasis on developments in the authors' laboratory. 相似文献

AbstractThis paper reviews aspects of laser physics, radiometry and photochemistry relevant to the use of low intensity light therapy delivered by lasers or conventional lamps. Current theories regarding the biophysical mechanisms of low intensity laser therapy are reviewed. Characteristics of laser radiation such as monochromaticity, coherence, collimation, speckle, beam profile, penetration depth and temporal modulation of irradiation, and the relevance of these factors to photon propagation are explained. Physical principles that describe light–tissue interactions are presented. The importance of irradiance and radiant exposure is discussed and methods of quantifying these values are shown. Clinical implications are briefly discussed. 相似文献

Abstract Objectives: To identify and evaluate the recent evidence of physical activity (PA) with or without diet counselling on cardiometabolic parameters in people who have schizophrenia. Methods: Keyword searches were used to identify articles since 2003 up to August 2009 from PubMed, SPORTDiscus, Cochrane Central Register of Controlled Trials, EMBASE, PEDro, DARE, ProQuest Dissertations and Theses and PsycINFO. There were no limitations in terms of study design and sample size. Data were extracted from each included study using key items that included participants, study design, intervention modalities, and outcome measures. Results: Thirteen studies met the inclusion criteria. Physical activity with or without diet counselling results in modest weight loss, reductions in systolic and diastolic blood pressure and decreases in fasting plasma concentrations of glucose and insulin. Identifying an optimal dose or intervention strategy for PA is not yet possible. Compliance to PA seems to be an important predictor of the PA response. Discussion: There is evidence that PA with or without diet counselling is feasible and effective in reducing weight and improving obesity-related cardiometabolic risk profile in people with schizophrenia. More research focussing on the effectiveness of different PA interventions in prevention and treatment of the metabolic syndrome in people with schizophrenia is highly needed. 相似文献

Abstract Objective: The purpose of this narrative review is to assess current physical therapy ethics knowledge by synthesizing literature published since 2000. Method: This review builds on an earlier analysis.6 A rigorous search of major databases (including Medline, CINAHL, and PubMed) was conducted using specific keywords and explicit inclusion and exclusion criteria. The final review included 27 peer-reviewed articles and three editorials/lectures. Results: Four themes of papers were identified that focused on (1) development of physical therapy ethics knowledge, (2) ethical issues related to conducting research, (3) how ethical issues are identified and managed and how ethical practice is taught, and (4) development of theoretical ethical decision-making models. Discussion: The literature reflects a steady growth in interest in physical therapy ethics. Some 'gaps' in knowledge have been addressed but others have not, such as the impact of the institutional environment and cultural dimensions of practice on ethical reasoning. Research studies, using mostly qualitative approaches, identify similar issues but a synthesis of the findings is made difficult by lack of consistency in purpose and study design. While inclusion of ethics content in physical therapy curricula is recommended, little is known about how this is currently being achieved. Ethical theories are poorly integrated into the discussion of ethics in practice. Conclusion: This review reveals the continuing need to ensure the development of physical therapy ethical knowledge by consistently incorporating both ethical theories and practice knowledge in education curricula and establishing a rigorous research agenda that accurately reflects the unique and multidimensional nature of clinical practice. 相似文献
