中国组织工程研究与临床康复 2007年第20期11卷 4038-4040页

作者：江昭黄红云陈琳郗海涛张峰刘彦铖刘瑞文姜超北京市虹天济神经科学研究院北京市西山医院暨北京康复中心神经外科北京市100041

目的:观察人胚胎嗅鞘细胞移植治疗额颞叶痴呆的有效性。方法:选择2006-04-04于北京市虹天济神经科学研究院和北京市西山医院暨北京康复中心神经外科就诊患者1例,男性,57岁,因“行为异常,性格及言语改变2年4个月”入院。患者知情同意并... 详细信息

目的:观察人胚胎嗅鞘细胞移植治疗额颞叶痴呆的有效性。方法:选择2006-04-04于北京市虹天济神经科学研究院和北京市西山医院暨北京康复中心神经外科就诊患者1例,男性,57岁,因“行为异常,性格及言语改变2年4个月”入院。患者知情同意并签署知情同意书。入院查体双侧hoffmann征可疑阳性,双侧Babinski征未引出。头颅MRI示双侧额颞叶脑沟、侧裂池增宽,脑实质萎缩明显,诊断为额颞叶痴呆。局麻下对患者进行人胚胎嗅鞘细胞移植术,于双侧额叶放射冠位置分别注射人胚胎嗅鞘细胞约100万个。移植前后使用日常生活活动量表评价患者神经功能。量表包括吃饭、穿衣、购物等20个日常行为活动项目。评分分4级:1级-可由自己完成,无困难;2级-完成有些困难;3级,需要帮助;4级-能力丧失,根本无法完成;如受试者从未做过的项目或无从了解的项目,则记为9,不计入总分。总分20分为正常;>20分为功能低下。结果:术后无任何并发症及不良反应。移植术后3周患者情感、认知方面有所改善。日常生活活动量表与术前比较,分数由43分下降至32分。术后6周电子邮件随访,神经功能继续改善。结论:人胚胎嗅鞘细胞移植后近期可部分改善额颞叶痴呆患者神经系统功能,提高生活质量,其恢复机制和长期效果有待进一步观察。
