肌萎缩侧索硬化的诊断、鉴别诊断

肌萎缩侧索硬化的诊断目前依旧是仰赖病史,且疾病早期和不典型病例需与多种疾病相鉴别。本文综述了目前国内外肌萎缩侧索硬化的诊断标准,常规需要鉴别的疾病以及鉴别要点,为临床诊断和鉴别诊断提供参考。     

Colles骨折手法复位的治疗体会

Colles骨折是指桡骨下端2～3cm以内、骨折远端向背及桡侧移位的骨折.本院门诊于1994年1月至2005年4月共诊治Colles骨折240例,其中40例关节内骨折,经闭合复位后,关节面的移位仍大于2mm者,收住院手术治疗;门诊复位满意的200例患者中186例获得随访,总结如下.     

神经纤维瘤蛋白在先天性脊柱侧凸患者成骨细胞和软骨细胞中的表达

目的：检测神经纤维瘤蛋白在先天性脊柱侧凸患者成骨细胞和软骨细胞中的表达。方法：6例先天性脊柱侧凸患者，在后路手术时取髂骨及髂骨生长板，分离、培养成骨细胞和软骨细胞，分别行碱性磷酸酶染色和甲苯胺蓝染色。逆转录-多聚酶链反应（RT—PCR）检测神经纤维瘤蛋白mRNA．间接免疫荧光和Westemblot检测神经纤维瘤蛋白在成骨细胞和软骨细胞中的表达。结果：先天性脊柱侧凸患者成骨细胞和软骨细胞中存在Ⅱ型神经纤维瘤蛋白表达，该蛋白主要分布在细胞浆，所表达蛋白为三磷酸鸟苷酶活化蛋白（GAP）活性较弱的Ⅱ型异构体。结论：先天性脊柱侧凸患者成骨细胞和软骨细胞中存在神经纤维瘤蛋白表达，但该蛋白是否通过对成骨细胞和软骨细胞的影响导致骨骼系统异常还有待于进一步研究。     

神经端侧缝合的应用与预后研究进展

1神经端侧缝合 端侧缝合应用于血管移植中主要适用于两条血管的外径相差太大，超过外径的1／2，剪成斜口仍不能端端缝合者、接受血管是受区唯一的一条供血动脉，切断后会引起肢体缺血或坏死者，如果将此方法应用于神经移植中也同样适用.     

前路器械内固定手术矫治脊椎侧凸

作者从１９７９年开始使用戴瓦氏手术，１９８３年开始使用斯伍基氏手术，至１９９４年共做５７例（男性２８例，女性２９例），年龄为９～２８岁。手术无死亡。术后并发症戴瓦氏手术：１例截瘫，２例椎体骨折伴螺丝钉拔出，２例螺丝钉折断，２例金属缆折断；斯伍基氏手术，１例杆折断，２例切口感染。     

Treatment of dislocation of distal radioulnar articulation by reconstruction of ulnar collateral ligament from pediculated partial ulnar flexor tendon of wrist

Background:Auricular pseudocyst,which is also calles serous perichondritis of thd auricle,is and aseptic local serous inflammatory mass in the perichondrium of the auricle.The cause is unknown,.It is difficult to the cured with a chronic course,and might transform into suppurative perichondritis because of incorrect treatment such as repeated puncture,and even necrosis occurs,resulting in deformation of the external ear.Objective:To study the therapeutic effect of magnetic application.Unit:Jianping County Hospital.Subjects:42 patients were included in this study,including 31 males,11 females aging 10 to 56 years,with unilateral attack in 38 cases,bilateral attack in 4 cases.No obvious cause was found in all of the cases.Local prominences occurred suddenly mostly at the navicular fossa,less at the triangular fossa,least in the cavity of concha.The site is felt hot and swelling with slight tenderness.The locus ranges from 0.5 cm to 1.5cm in diameter.The disease course ranges between 3 and 30 days.Interention:The intracapsular fluid was withdrawn out from the locus in all the pwatients.Two magnetic pieces of 100-170mT in intensity were chosen and fixed on both sides of the locus by wadhesive plaster with the S and N poles opposited.The magnetic pieces of the Npole were applied 24 hours a day.But the S pole should be taken off at night and 5-10 minutes every 1-2 hours in daytime.The application method must be clearly taught to the patients to avoid local ischemic change because of persistent pressure.The poles of the magnetic pieces should also be told to the pwatients lest the pwatients fixed the magnetic pieces in a contrary way.The treatment courese was 1 week but 2 weeks in patients wih larger loci.Result:All the patients were cured with no local induration,thickness,deformation,or dispigmenttation.No recurrence occurred after 3 months of telephone following up.Conclusion:The treatment of magnetic application is easily performed,safe,reliable,cheap and free of side effects with significant therapeutic effect.     

特发性脊柱侧凸病因学研究进展

特发性脊柱侧凸病因尚不清楚,本文从肌肉-骨骼系统、内分泌系统、神经系统、营养代谢及基因分子生物学等方面综述其病因学研究。多数学者认为:肌肉、椎体和椎间盘的改变只是其病理发展过程的一个阶段,营养及代谢因素缺乏所致脊柱侧凸经过治疗可以逆转;褪黑素的缺乏可能通过干扰本体感受系统的正常对称生长而形成脊柱侧凸;5-羟色胺对维持正常姿势性肌肉张力和姿势平衡可能有重要作用;钙调蛋白、褪黑素可能通过调控钙激活的钙调蛋白而起作用;遗传因素的作用已得到广泛的认同,但是其遗传方式仍存在争议。     

骶尾椎侧位在CR摄影中的改进投照法

我院于2003年10月引进美国柯达CR-900成像设备，我们住应用后发现，进行骶尾椎侧位投照时，若按传统投照法，计算机上所显示的图像质量差，或是“斑点”大、或是灰雾度大，不清晰，无法打印X线胶片。我们经过实践操作、总结，探索出了CR摄影中的骶尾椎侧位改进投照法。现介绍如下。
