腰腿痛的常见病因概述

腰腿痛的常见病因概述中山医科大学附属第一医院（５１００８０）庞水发腰腿痛不是一个独立疾病，而是许多疾病的常见和共有症状。在门诊，患者常以此主诉就诊。据一些资料统计，西方国家约５０％～８０％的成人曾患过腰痛；美国每年有２０００万人因为腰痛看医生；在英国...     

臂丛损伤患者的生存质量调查分析

Objective To investigate the quality of life on brachial plexus injury patients in crosssectional study method and acquire related data. To analysis the effect factors and try to study on the methods which help to improve the quality of life of these patients. To our knowledge, this is the first study that measures quality of life of the brachial plexus injury patients in China. Methods Research participants completed the Chinese version of the World Health Organization Quality of Life Assessment-Bref (WHOQOL-BREF) and the 5-items version of International Index of Erectile Dysfunction Questionnaire (IIEF-5) for male.Data were typed into computer and analyzed with SPSS version 13.0. Correlations between domain scores and hospital stay, age, and family monthly income variables were analyzed with Spearman non-parameter correlation analysis. Results Fifty-one valid questionnaires were retrieved. The average score of these patients in physical, psychological, environment domains were 11.47 ± 2.36, 12.37 ± 2.28 and 11.62 ± 2.22, respectively. They were significantly lower than the norm groups in national studies which were 15.8 ± 2.9, 14.3 ±2.5 and 13.2 ± 2.4 (P ＜ 0.01 ). The average score of IIEF-5 was ( 17.83 ± 4.65), significantly lower than the normal score of 22 (P ＜ 0.01 ). Significant correlation was found among physical domain and age(P ＜ 0.05),family monthly income (P ＜ 0.05) and IIEF-5 score(P ＜ 0.01). Psychological domain also has significant correlation with IIEF-5 score (P ＜ 0.05) and so does environment domain with family monthly income (P ＜0.05). Conclusion Brachial plexus injury patients showed a reduction in quality of life scores. Even though the physical aspect was the most affected, there is evidence that the psychological, environmental domains and erectile function remained far from the ideal conditions expected for the general population. The effect factors are complex and there still remain much work to do.     

人源性同种异体去细胞外周神经材料标准制备方法的研究

目的 对目前文献报道使用的5种不同方法制备的人源性同种异体去细胞外周神经材料进行综合分析比较其优劣,以确定可供临床使用的标准的制备流程.方法 将人源性神经按5种不同方法进行化学萃取,制备的外周神经支架材料分别行苏木精-伊红(HE)染色、免疫组化(S-100、Col I)和透射电镜、氮含量测定等检测,观察5种方法去除许旺细胞、髓鞘和轴突等抗原成分以及基底膜保存完好的情况.结果 分别萃取2次持续24 h组神经的HE染色显示去除细胞和轴突彻底,纵切片上未见任何细胞,红染的神经内膜呈波浪状纵形排列,轴突、髓鞘结构消失而形成管柱状空隙;S-100染色呈阴性;Col I染色结果可以看出其结构呈松散不规则的棕黄色结构,而其它处理组则结构相对整齐的纵向带状结构.透射电镜显示该组与各处理之间髓鞘去除差异无统计学意义.氮含量测定显示该组蛋白含量比值最低.结论 使用Triton X-100处理24 h再分别脱氧胆酸钠24 h持续萃取2次,可作为供临床使用的制备人源性去细胞同种异体神经支架材料的标准流程.     

培养中的雪旺氏细胞对脊髓前角神经元的营养作用

通过隔玻片ＳＤ大鼠瓦勒氏变性远段坐骨神经获得的雪旺氏细胞（ＳＣ）与胎龄１４天的ＳＤ大鼠胚胎脊髓前角神经元（ＳＡＨＮ）联合培养，用倒置显微镜、Ｎｉｓｓｌ染色、ＳＡＨＮ免疫学观察，证实培养中的ＳＣ具有维持神经元成活和促进突起生长的作用。在这二种神经营养因子作用下，脊髓前角神经元胞体增大，突起生长可达数倍胞体长度。为认识和研究运用神经营养学说促进神经再生提供了新资料。     

雪旺细胞源运动神经营养蛋白对周围神经再生的影响

目的：研究雪旺细胞源运动神经营养蛋白对周围神经再生的影响。方法：６０只ＳＤ大鼠均分为３组，Ａ和Ｂ组分别在桥接于大鼠右侧坐骨神经断端之间的硅胶管内加入２６ＫＤ和５０ＫＤ的雪旺细胞源运动神经营养蛋白，Ｃ组加ＰＢＳ液作为对照。术后１～６月每隔半月测定实验侧坐骨神经功能指数，术后３月测定实验侧坐骨神经的电生理和形态学指标。结果：Ａ和Ｂ组实验侧坐骨神经的功能指数、电生理和形态学指标与Ｃ组比较，差别有非常显著性。结论：２６ＫＤ和５０ＫＤ雪旺细胞源运动神经营养蛋白对周围神经再生有促进作用。     

大力推广和深入发展显微外科大有可为

自从1960年Jacobcon做小血管显微吻合实验成功以来,我国陈中伟(1963年)首先报道世界上第1例断肢再植成功,接着断指再植亦成功,由此掀起开展显微外科技术的热潮,大大提高我国显微外科在世界上的威望。现在显微外科已被国家标准学科分类列为三级学科,这预示着显微外科在下个世纪将会有一个大的发展,它必将对提高外科各个领域的医疗技术水平起到积极而又重要的作用。显微外科的临床应用断肢(指)再植　断指再植至今已有30余年的发展历程。60年代为开创期,断指再植的成活率仅为51%;70年代为发展期,再植成活率提高到92.9%;80年代是硕果期,最显著…     

许旺细胞源神经营养因子在运动神经元轴突逆行运输的研究

目的：研究许旺细胞源神经营养因子能否被脊髓运动神经元逆行运输。方法：氯氨T氧化法标记许旺细胞源神经营养因子，新生SD大鼠经一侧小腿肌内注射^125I标记的许旺细胞源神经营养因子，测一左、右侧腰段脊髓的放射性记数。结果：注射侧腰段脊髓放射性记数明显高于对侧。结论：脊髓运动神经元可以逆行运输许旺细胞源神经营养因子。
