补阳还五汤在骨伤科的应用

补阳还五汤出自晚清名医王清任所著《医林改错》,该方是益气活血法的代表方,具有补气活血通络的效果,主治气虚血瘀所致的中风。根据异病同治的原则,近年来该方在骨伤科的应用研究中取得较大进展,现将其综述如下。     

骨科外固定支架对骨生长影响的回顾性研究

目的研究骨科外固定支架对骨折愈合的影响。方法对我院2002年1月～2006年5月在骨科住院使用外固定支架治疗的患者进行回顾性研究，对采用静态固定和动态固定外固定支架的骨折端生长情况进行分析，观察骨折端是否出现局部性的骨质疏松、迟缓愈合、病理骨折等。结果共282例，其中静态固定组191例，骨质疏松的发生率为35．1％（67／191），迟缓愈合率为19．9％（38／191），病理骨折率为7．9％（15／191）。动态固定组中，骨质疏松的发生率为19．8％（18／73），迟缓愈合率为7．7％（7／91），没有发生再骨折的情况。统计分析各项指标P〈0．05，两组之间的差异有统计意义。结论支架外固定是一种治疗四肢骨折有效的方法，简便易行，并发症少。规范合理的外固定支架动态固定对骨折的愈合具有明显的正相影响，能够有效降低应力遮挡，提高骨折生长质量，加快骨折愈合，减少再次骨折的发生。     

"定骨舒筋"用于髌骨骨折早期康复的临床研究

目的观察"定骨舒筋"手法用于髌骨闭合性骨折早期康复的疗效。方法60例伤后半个月的病例,对照组30例在夹板固定下行股四头肌收缩活动;治疗组30例去除夹板,用手法对骨折端进行有效的固定而进行主动和被动的关节活动。结果治疗组平均愈合时间4.33周,比对照组明显缩短(P<0.01),膝关节活动度比对照组明显提高(1个月P<0.01;2个月P<0.05),3个月膝关节功能积分优级率比对照组高(P<0.05)。结论"定骨舒筋"对骨折的提前愈合和关节的尽早恢复具有良好的临床疗效。     

腰宝袋治疗腰痛证的临床观察与实验研究

腰宝袋又名弥伤蠲浊强腰袋，是以弥伤蠲浊、强腰益肾为主要功效的一种保健性治疗药袋。1993年初通过了陕西省医药管理局组织的专家鉴定，并获得批号(陕西械准字第364696号)，1993年4月获全军科技成果展览会银奖。该产品由第四军医大学康复医疗用品厂研制，后于1992年5月～12月，分别由第四军医大学唐都医院骨科、西京医院理疗科、陕西省中医药研究院附属医院进行了临床疗效观察，由陕西省药品检验所进行了本品内袋药物的药效学试验和急性毒性试验，现将结果报告如下。     

Osmic acid staining of myelin sheath in normal and regenerated peripheral nerves

Objective: To introduce a practical, economical, and time-saving method to stain (with osmic acid) the myelin sheath in normal and regenerated peripheral nerves. Methods: A total of 12 Sprague Dawley rats, weighing 250-320 g (mean =276 g±38 g), were divided into two groups: a normal nerve group (n=6) and a regenerated nerve group (n=6). In the normal nerve group, the ventral and dorsal roots of L4 to L6 and their sciatic nerves were harvested for histological analysis. While in the regenerated nerve group, the right sciatic nerves were severed and then repaired with an epineurial microsuture method. The repaired nerves were harvested 12 weeks postoperatively. All the specimens were fixed in 4% paraformaldehyde and transferred to 2% osmic acid for 3-5 days. Then the specimens were kept in 75% alcohol before being embedded in paraffin. The tissues were cut into sections of 3μm in thickness with a conventional microtome. Results: Under a light microscope, myelin sheaths were clearly visible at all magnifications in both groups. They were stained in clear dark colour with a light yellow or colorless background, which provided high contrast images to allow reliable morphometric measurements. Morphological assessment was made in both normal and regenerated sciatic nerves. The ratios of the myelin area to the fibre area were 60. 28%±7. 66% in the normal nerve group and 51. 67%±6. 85% in the regenerated nerve group, respectively (P<0.01). Conclusions: Osmic acid staining is easy to perform and a very clear image for morphometrical assessment is easy to obtain. Therefore, it is a reliable technique for quantitative evaluation of nerve morphology.     

手法复位推拿治疗对椎动脉型颈椎病患者血流动力学的影响

目的探讨手法复位推拿治疗对椎动脉型颈椎病(CSA)血流动力学的影响。方法选择诊断明确的CSA患者240例随机分为手法复位推拿(治疗组)和点滴丹参(对照组)治疗,治疗组用推拿治疗,观察患者治疗前后眩晕、恶心呕吐、头痛和经颅多普勒(TCD)的变化。结果治疗组治疗后眩晕、恶心呕吐、头痛计分与治疗前比较差异均有高度显著性(P<0.01),而对照组治疗后仅眩晕与治疗前比较差异有显著性(P<0.05);治疗组恶心呕吐、头痛计分与对照组比较差异有高度显著性(P<0.01)。治疗组治疗后基底动脉、左侧椎动脉、右侧椎动脉的PS、TAMn与治疗前比较差异有高度显著性(P<0.01);治疗组治疗后基底动脉、左侧椎动脉、右侧椎动脉的PS与对照组比较差异有高度显著性(P<0.01),且基底动脉的TAMn与对照组比较差异亦有高度显著性(P<0.01)。结论手法复位推拿可明显改善CSA患者的眩晕、恶心呕吐和头痛等体征,明显提高椎—基动脉的血流速度。
