肝移植患者术后住院期间的中枢神经系统并发症

目的探讨肝移植术后住院期间中枢神经系统并发症的发病情况、临床和神经影像学特征及可能的危险因素及预后。方法对中山大学附属第一医院1996年1月至2005年6月间共337例患者的358次肝移植手术进行回顾性研究。结果术后住院期间患者出现中枢神经系统并发症共58例，发生率16．2％，病死率41．4％。最常见的表现为肝移植脑病（10．3％），次之为癫痫（4．5％）和脑血管疾病（2．8％）。与无中枢神经系统并发症的肝移植患者相比，术后发生中枢神经系统并发症者的年龄、是否再次肝移植及病死率差异有统计学意义（P〈0．05）。结论肝移植术后住院期间中枢神经系统并发症的发生率及病死率较高，直接影响患者的生活质量及预后。年龄偏大、再次肝移植可能是其危险因素。     

少年儿童颞下颌关节紊乱综合征的错雅(牙合)特征

①目的 探讨少年儿童颢下颌关节紊乱综合征(TMJD)的错拾特征。②方法 用一般口腔检查工具对青岛地区的550例TMJD病人进行拾检查。③结果 80．0％的病人有不同程度的错He，其中个别牙齿错位所占的百分率最高(42．4％)，其次为高度不调、长度不调和宽度不调；不同牙龄期病人错He特征不同。④结论 本研究结果可以作为TMJD早期正畸治疗以及治疗时对错He分析和诊断的参考。

NF-κB在中枢神经系统损伤和修复中的作用(英文)

细胞核因子-κB(nuclear factor kappa B,NF-κB)家族是B淋巴细胞核因子,它能够与免疫球蛋白κ链增强子结合并增加各种基因的表达活性。NF-κB通过典型和非典型途径的激活来控制和调节各种生理病理过程。在中枢神经系统,NF-κB调控炎症反应、神经损伤后的神经细胞凋亡等,它可以促进中风等缺血性脑损伤的脑梗死面积和神经元死亡,同时又对神经元的存活有重要影响。NF-κB激活是神经康复的重要组成部分,它能够保护神经元免于由氧化应激和脑缺血诱导的神经元凋亡和变性,阻滞NF-κB活性将影响它的神经保护机制。NF-κB这种对神经元存活和死亡的双重效应取决于NF-κB激活的亚单位类型、激活所处的损伤位置以及损伤后修复的时程。     

Innervation of the trapezius muscle: is cervical contribution important to its function?

OBJECTIVE: To study the effect of the cervical plexus and the accessory nerve to the function of the trapezius muscle. STUDY DESIGN AND SETTING: Eighteen adult male Sprague-Dawley rats were randomly divided into three groups. The neurotomies were performed in the left sides and the right sides served as within-subject controls. In group A, the accessory nerve was transected. The C2-5 were transected in group B, and both of the accessory nerve and C2-5 were cut in group C. The electrophysiologic, myophysiologic, and histologic changes of the muscles were measured. RESULTS: There were significant differences (P < 0.05) between the three groups in the recovery rates of the transverse area of the muscles. The CMAP recorded from the experimental sides in group B were similar to the control sides. The values of the maximum tension of the tetanus contraction between the two sides showed no differences either (P > 0.05). CONCLUSION: The accessory nerve supplies the most important motor input to the trapezius. Motor innervations of the cervical plexus are not very significant.     

不同部位静脉注射对无痛人工流产术的影响

目的 :观察不同部位静脉注射对无痛人工流产术的影响。方法 :随机将 2 0 0例要求行无痛人工流产术的患者分成二组 ,一组静脉注射部位为手背静脉组 ,另一组静脉注射部位为肘部浅静脉 (贵要静脉或肘正中静脉 )组 ,观察静脉推注异丙酚时患者的注射部位有无疼痛症状。结果 :肘部浅静脉注射部位疼痛感明显轻于手背静脉 ,肘部浅静脉注射部位的麻醉起效时间快于手背静脉 ,两组差异有显著性 (P <0 0 5 )。结论 :选择肘部浅静脉注射异丙酚可减轻患者注射部位的疼痛 ,可在短时间内取得理想的麻醉效果。     

立体定向技术治疗癫痫性精神病的体会

目的：探讨多靶点组合对癫痫性精神病的治疗效果。方法：采用立体定向技术，运用多元化定位和多靶点组合，射频热凝脑内核(团)治疗癫痫性精神病53例。术前、术后均进行总疗效评定量表(GAS)和癫痫的国际疗效评价进行疗效评定。结果：53例中显效37例，进步16例。结论：双侧胼胝体、杏仁核、内侧隔区及单侧红核前区多靶点组合治疗，对癫痫性精神病的治疗有明显作用。     

头孢噻肟钠聚合物测定实验条件的改进

Intraosseous ganglion about to cause a fracture of the glenoid: a case report

Intraosseous ganglia of the glenoid are rare, and their etiology is unknown. This report describes a case of an intraosseous ganglion about to cause fracture of the glenoid. The patient was a 61-year-old woman with a painful left shoulder with a limited range of motion. Her symptoms did not improve after non-operative treatment. Arthroscopic examination showed a cartilage defect and erosion in the posteroinferior portion of the glenoid, behind which computed tomography (CT) showed a cystic lesion of the glenoid. There was no communication between the cyst and the joint space. The patient was treated by curettage and an autogenous cancellous bone graft from the iliac crest. Two years after the operation, the patient was almost free from pain, and CT showed good integration of the bone graft.
