岩斜脑膜瘤的伽玛刀治疗

目的评估伽玛刀治疗岩斜区脑膜瘤的疗效。方法1995～2000年,我们对66例岩斜区脑膜瘤病人进行了伽玛刀治疗,肿瘤体积0.32～29.4cm3,平均(5.87±5.10)cm3。周边剂量为7～14.4Gy,平均(12.4±1.6)Gy;中心剂量16～65Gy,平均(27.9±5.9)Gy。结果60例随访25～94个月,平均(57.8±22.3)个月:肿瘤体积缩小23例(38.3%),不变35例(58.3%),增大2例(3.3%);神经系统症状好转37例(61.7%),稳定20例(33.3%),加重3例(5.0%)。无严重并发症发生。结论伽玛刀治疗能很好地控制肿瘤,副作用轻微,可作为神经外科较大肿瘤的辅助性治疗,也可作为较小肿瘤或不适合手术的病人的主要治疗。     

巢蛋白在已分化的神经干细胞中表达时程的研究

目的 探讨神经干细胞分化过程中巢蛋白(nestin)表达的时程变化。方法 在细胞分化的不同时间进行免疫荧光染色。结果 在神经干细胞分化早期，巢蛋白表达仍呈阳性。随着分化的神经细胞、星形胶质细胞或少突胶质细胞逐渐发育成熟，巢蛋白表达渐渐减弱，到第7周时巢蛋白表达完全消失。结论 巢蛋白表达不仅是神经干细胞的重要标志，同时也出现在神经干细胞分化的早期，而且随着细胞逐渐分化成熟，其表达显著下降。体外培养情况下至分化的第7周即完全消失。     

神经导航技术在深部脑胶质瘤切除术中的应用

目的 研究神经导航技术在深部脑胶质瘤手术中的应用。方法 根据导航工作站所显示深部胶质瘤的三维结构，制定手术计划，在观察棒导航下寻找病灶，完成胶质瘤切除术。结果 在神经导航下完成68例深部脑胶质瘤切除，定位准确，减少了对周围组织的损伤，术后无明显神经功能障碍。结论 神经导航在部位深、病灶小、肉眼难以识别的胶质瘤等手术中的应用，可有效地保护神经功能。     

正交函数分光光度法测定芫花根注射液中二萜原酸酯类的含量

芫花根注射液是一种粗制剂,成分复杂,含量测定困难,其主要引产成分为芜花酯甲,芫花酯乙,芫花酯丙和芜花酯丁等瑞香烷型二萜原酸酯类,其中以芫花酯甲含量最高。本文以芫花酯甲为标准品,用正交函数分光光度法,测定芫花根注射液中总瑞香烷型二萜原酸酯的含量。其平均回收率为98.9%,变异系数1.6%(n=9)。     

准分子激光原位角膜磨镶术患者视网膜微循环血流的研究

目的 本研究主要观察LASIK中负压吸引对视网膜微循环血流的影响。方法 采用海德堡视网膜血流仪分别对实施LASIK手术的低度，中度和高度的近视患者共38例62眼进行检测，测量视盘大血管，视盘颞侧盘沿，视盘鼻侧盘沿，颞侧视盘旁视网膜，鼻侧视盘旁视网膜和巩膜筛板的血流，并对其手术前后的血流量，血流速和红细胞移植速率进行统计分析。结果 LASIK手术前后，视盘大血管，视盘颞侧盘沿，视盘鼻侧盘沿，颞侧视盘旁视网膜，鼻侧视盘旁视网膜和筛板的血流量，血流速和红细胞移动速率均无显著性差异。结论 LASIK中负压吸引对视网膜微循环血流无临床病理性影响。

An alternative method for restoring opposition after median nerve injury: an anatomical feasibility study for the use of neurotisation

Opposition, one of the most important functions of the hand, is lost or impaired after median nerve injury. Complete recovery does not always occur after treatment, and various techniques of opponensplasty are used for restoring opposition. This study was performed in order to develop an alternative method for selective restoration of thenar muscle function. Ten arms from 5 cadavers were used. The median nerve with its thenar motor branch (Tb) and the anterior interosseous nerve with its motor branch to pronator quadratus (PQb) were prepared in the distal forearm. The mean widths and the number of myelinated fibres of these nerves were: PQb 1.3±0.10 mm, Tb 1.4±0.12 mm and PQb 912±88 mm, Tb 1020±93 mm. The minimum necessary distance from the distal flexor crease of the wrist for neurotisation of the Tb by the PQb was 60±5.41 mm. It was concluded that PQb‐Tb neurotisation would be possible anatomically. The advantages are that motor function is reestablished with a motor nerve, the diameters and the number of myelinated fibres of both nerves are similar, the loss of function after denervation of the pronator quadratus is slight and opponensplasty still remains as a final option.     

髓母细胞瘤的临床病理,免疫组化及电镜观察

报道３０例儿童髓母细胞瘤，其中小脑蚓部２５例，小脑半球５例。组织类型：经典型１９便，促纤维增生型１０例，肌细胞型１型。免疫组化标记Ｓ－１００，ＮＳＥ，ＮＦ，ＧＦＡＰ阳性率分别为９０％，８５％，８５％，６０％，显示有向神经元和／或胶质细胞双向分化的能力。３例电镜结果眯支持髓母细胞瘤是具有双向分化潜能的原始神经外胚层来源的肿瘤。
