目的:分析高血压脑出血患者手术后并发症与生活质量的相关性。方法:随机选取80例高血压脑出血手术后患者,术后1个月按GOS评分,分别统计GOS≥4分和GOS≤3分患者并发症发生率,并分析并发症与GOS评分的相关性。结果:GOS≤3分患者的手术后并发症发生率高于GOS≥4分的患者(P0.05);多因素回归分析检出肺部感染、水电解质平衡紊乱、营养不良、中枢高热与GOS评分呈正相关(β0,OR1)。结论:肺部感染、水电解质平衡紊乱、营养不良、中枢高热是高血压脑出血患者手术后生活质量的重要影响因素。     

干细胞移植治疗缺血性脑梗死后脑内迁移的MRI监测

传统观点认为神经元在出生前或出生后不久即失去再生能力,中枢神经损伤后神经细胞为不可逆性死亡。随着干细胞生物学特性研究的深入,冲破了成年生物体内神经细胞不可再生的传统观念。干细胞移植治疗逐渐成为近年研究的热点,迄今已有多篇有关干细胞移植治疗缺血性脑梗死动物模型的文献报道［1-7］。     

MRA与动脉质子自旋标记联合对短暂性脑缺血预后评估的应用

目的 评价磁共振血管造影(magnetic resonance angiography,MRA)及动脉质子自旋标记(arteiral spin labeling proton,ASL)联合对短暂性脑缺血发作(transient ischemic attack,TIA)预后评估价值.方法 90例颈动脉TIA患者根据DWI表现分为单纯型TIA 和暂时性症状合并梗死(transient symptoms associated with infarction,TSI型)2组.90例患者均分别行MRA及ASL检查,根据MRA及ASL表现分为4型:A型(MRA及ASL均异常)、B型(MRA及ASL均正常)、C型(MRA正常,ASL异常)、D型(MRA异常,ASL正常).结果 在A型表现里,单纯型TIA占20%,TSI型占80%;在B型的表现里,单纯型TIA占94.7%,TSI型占5.3%.A、B 2型在2组间进行比较,差异有统计学意义(P<0.01).结论 MRA及ASL联合检查可对TIA患者脑血管和脑灌注进行诊断,为临床对TIA患者预后评估提供影像学依据.

桥脑出血或梗死继发双侧小脑中脚Wallerian变性及肥大性下橄榄核变性的MR浅析(附5例报告)

目的探讨继发于桥脑出血或梗死并同时继发双侧小脑中脚Wallerian变性(WD)及肥大性下橄榄核变性(HOD)的发病机制、MRI特征及其与原发病灶关系,以期提高对该病的认识。方法回顾性分析5例继发于桥脑出血或梗死同时继发双侧小脑中脚WD及HOD的MRI表现,同时根据MRI表现和解剖结合文献对其进行分析。5例均行MRI常规序列和DWI、SWI或T2*WI序列扫描。结果 5例中3例桥脑基底部背侧出血,均继发双侧HOD及双侧小脑中脚WD。1例桥脑右背侧出血继发右侧HOD及双侧小脑中脚WD,1例桥脑左背侧梗死继发左侧HOD及双侧小脑中脚WD。HOD表现为单侧或双侧下橄榄核体积增大,T1WI呈等或稍低信号,T2WI呈稍高或高信号,FLAIR呈等或稍高信号,DWI呈等或稍高信号,ADC图呈等或稍高信号,SWI或T2*WI呈等或稍高信号,其对原发出血病灶显示最好。双侧小脑中脚WD早期表现为对称性DWI图高信号,ADC图低信号,T2WI稍高信号,T1等信号;中后期表现为DWI图等或稍低信号,ADC图稍高信号,T1WI稍低信号,T2WI稍高信号。结论肥大性下橄榄核变性多继发于桥脑背盖部病变,并且有特定的发病部位和较为特征的MRI表现;双侧小脑中脚对称性异常信号不难发现,但当同时存在桥脑出血或梗死、HOD及双侧小脑中脚对称性异常信号时要考虑到是桥脑出血或梗死同时继发HOD及双侧小脑中脚的WD,而不要盲目的把它们误认定为是三个原发孤立病变。     

脊柱骨巨细胞瘤的CT及MRI表现

目的探讨脊柱骨巨细胞瘤的影像学特征,并与病理对比,旨在提高对本病的认识。方法回顾性分析18例经手术及病理证实的影像及病理结果。结果脊柱骨巨细胞瘤以骶椎发生率最高,病变可侵犯单一或多个椎体,骶椎病变均侵犯多椎体。CT可见椎体呈中心性骨质破坏10例,偏心性骨质破坏8例,8例病变内可见骨嵴或骨性间隔。12例伴有软组织肿物,合并椎体压缩骨折10例,4例增强扫描呈中-重度强化。MRI扫描显示病变T1WI呈等低信号,T2WI呈等低信号或混杂为主,STIR呈不均匀高或稍高信号。结论脊柱骨巨细胞瘤影像学表现具有一定特征,CT与MRI有重要诊断价值。

In vivo tracing of superparamagnetic iron oxide-labeled bone marrow mesenchymal stem cells transplanted for traumatic brain injury by susceptibility weighted imaging in a rat model

Objective：To label rat bone marrow mesenchymal stem cells （BMSCs） with superparamagnetic iron oxide （SPIO） in vitro, and to monitor the survival and location of these labeled BMSCs in a rat model of traumatic brain injury （TBI） by susceptibility weighted imaging （SWI）sequence.Methods：BMSCs were cultured in vitro and then labeled with SPIO. Totally 24 male Sprague Dawley （SD） rats weighing 200-250 g were randomly divided into 4 groups： Groups A-D （n=6 for each group）. Moderate TBI models of all the rats were developed in the left hemisphere following Feeney＇s method. Group A was the experimental group and stereotaxic transplantation of BMSCs labeled with SPIO into the region nearby the contusion was conducted in this group 24 hours after TBI modeling. The other three groups were control groups with transplantation of SPIO, unlabeled BMSCs and injection of nutrient solution respectively conducted in Groups B, C and D at the same time. Monitoring of these SPIO-labeled BMSCs by SWI was performed one day,one week and three weeks after implantation.Results： Numerous BMSCs were successfully labeled with SPIO. They were positive for Prussian blue staining and intracytoplasm positive blue stained particles were found under a microscope （×200）. Scattered little iron particles were observed in the vesicles by electron microscopy （×5000）. MRI of the transplantation sites of the left hemisphere demonstrated a low signal intensity on magnitude images,phase images and SWI images for all the test rats in Group A, and the lesion in the left parietal cortex demonstrated a semicircular low intensity on SWI images, which clearly showed the distribution and migration of BMSCs in the first and third weeks. For Group B, a low signal intensity by MRI was only observed on the first day but undetected during the following examination. No signals were observed in Groups C and D at any time points.Conclusion：SWI sequence in vivo can consecutively and noninvasively trace and demonstrate the status and distribution of BMSCs labeled with SPIO in the brain of TBI model rats.
