    • 摘要: 报告1例产前超声联合胎儿颅脑磁共振成像(magnetic resonance imaging,MRI)诊断胎儿脑灰质异位合并细丝蛋白A(filamin A,FLNA)基因突变的病例.患者超声检测结果显示侧脑室外壁凹凸不平,颅后窝池宽,透明隔间腔略窄,小脑延髓池轻度增宽.MRI诊断结果为胎儿脑灰质异位合并大枕大池.羊水穿刺获得脱落细胞,采用全外显子测序和基因拷贝数变异(copy number variations,CNV)分析,显示与脑灰质异位疾病相关的FLNA基因外显子出现缺失,其为可能导致脑灰质异位的致病基因.因此,超声结合胎儿颅脑MRI能有效提高脑灰质异位的诊断率,其中染色体检查可筛查出部分致病原因,并对下次妊娠提供帮助.该病例可丰富临床医生对胎儿大脑灰质异位的产前超声检查、合并畸形、临床表现等的认识.

    • 摘要: Objective To evaluate the relationship between subventricular zone(SVZ), the shortest distance from tumor centroid to the edge of the lateral ventricles (TV) and prognosis of patients with glioblastoma multiforme (GBM). Methods The clinical data of 130 patients with GBM in our hospital since 2006 to 2016 were retrospectively reviewed and 45 persons of these patients with SVZ were involved. Chi-square test and survival analysis was performed to identify prognostic factors associated with GBM. Results Chi-square test indicated that there were no significant differences in the distribution of age, gender, tumor location, tumor volume, preoperative epilepsy and the extent of resection in these two groups with involvement of SVZ or not (P>0.05). Similarly, there were no statistically significant differences in the distribution of age and sex, tumor location, tumor size, preoperative epilepsy between TV0.05). Univariate analysis showed that adjuvant therapy (HR=0.765, 95%CI:0.557-0.998, P=0.045), SVZ (HR=2.996, 95%CI:1.995-4.500, P0.05). When the parameters with statistical significance identified by univariate analysis were included in the multivariate analysis, the results showed that adjuvant therapy (HR=0.540, 95%CI:0.333-0.875, P=0.012), SVZ (HR=2.634, 95%CI:1.725-4.022, P0.05). When the parameters with statistical significance identified by univariate analysis were included in the multivariate analysis, the results showed that adjuvant therapy (HR=0.726, 95%CI:0.529-0.997, P=0.048) and TV(HR = 3.234, 95%CI: 1.711- 6.112, P0.05),同样,年龄、性别、肿瘤方位、肿瘤体积、术前癫痫、肿瘤切除程度在TV0.05).单因素分析表明辅助性治疗(HR=0.765,95%CI:0.557~0.998,P=0.045)、室管膜下区(HR=2.996,95%CI:1.995~4.500,P<0.01)和手术切除程度(HR=0.472,95%CI:0.313~0.713,P<0.01)是生存时间的预测因素,将上述具有明显统计学意义的因素纳入多因素分析,结果表明切除程度(HR=0.563,95%CI:0.366~0.867,P=0.009)、辅助性治疗(HR=0.726,95%CI:0.529~0.997,P=0.048)、室管膜下区(HR=2.634,95%CI:1.725~4.022,P<0.01)都与胶质母细胞瘤患者的生存期相关.而在肿瘤累及室管膜下区的患者中,单因素分析表明辅助性治疗(HR=0.535,95%CI:0.332~0.863,P<0.01)和TV(HR=3.297,95%CI:1.738~6.253,P<0.01)都是可预测胶质母细胞瘤患者预后的预后因子,当将上述两个因素纳入多因素分析时,结果表明辅助性治疗(HR=0.540,95%CI:0.333~0.875,P=0.012)以及TV<30 mm(HR=3.234,95%CI:1.711~6.112,P<0.01)仍然与胶质母细胞瘤的预后有关.结论 肿瘤累及室管膜下区以及TV<30 mm是胶质母细胞瘤的预后危险因素.

    • 摘要: 目的 探讨超顺磁氧化铁纳米颗粒(SPIOs)对成体大鼠室管膜下区(SVZ)神经前体细胞(NPCs)的在体标记及MR示踪成像的可行性.方法 通过脑立体定位仪向大鼠(n=7)右侧脑室前角前缘区注射3μl SPIOs(浓度7 mg Fe/ml),于注射当天开始腹腔注射5-溴脱氧尿嘧啶核苷(BrdU),连续注射1周.所有实验动物均于术后第1、3、7、14天进行MR扫描,第14天MR扫描后行灌注固定取脑,标本分别行普鲁士蓝染色以及普鲁士蓝与BrdU免疫组织化学双重染色.结果 在7例实验动物中,注射后SPIOs均大部分位于右侧侧脑室前角前缘区域,仅部分进入脑室系统.矢状位T2* WI能较好地显示SPIOs经颅顶部注入脑内的路径以及沿吻侧迁移流(RMS)向嗅球(OB)区分布的过程,磁共振伪影适中,示踪成功率达100%.染色结果显示SPIOs能较好地标记NPCs,SVZ、RMS以及OB区平均标记率分别约为75.5%、42.3%、23.6%.结论 SPIOs能有效地在体标记成体大鼠SVZ的NPCs,MRI能动态地监测标记后的NPCs沿RMS向OB方向迁移的过程.%Objective To explore the feasibility of in vivo labeling of adult rat neural progenitor cells (NPCs) in subventricular zone (SVZ) with superparamagnetic iron oxide particles (SPIOs) for tracking of magnetic resonance imaging (MRI).Methods A total of 7 SD rats were stereotactically injected with 3 μl SPIOs (7 mg Fe/ml) into anterior horn of right lateral ventricle and then 5-bromo-2'-deoxyuridine (BrdU) was injected intraperitoneally once daily for 1 week.MRI was performed at 1,3,7 and 14 days post-injection.After the final MRI scan,all rats were transcardially perfused and their brains removed and fixed.The sections were processed for Prussian blue iron staining and Prussian blue plus BrdU immunohistochemical staining.Results In all experimental animals,SPIOs were predominantly located in the anterior horn of right lateral ventricle and partial SPIOs entered the ventricular system.A needle path and a distribution of SPIOs along rostral migratory stream (RMS) towards olfactory bulb (OB) were depicted at the sagittal view of T2 * WI,moderate MR artifact was visible and SPIOs tracking NPCs were successful (success rate of 100%).The result of staining showed SPIOs labeling NPCs were effective.And the labeling rates were 75.5%,42.3%,23.6% in SVZ,RMS and OB respectively.Conclusion Effective in vivo labeling of adult rat NPCs in SVZ with SPIOs is feasible.And dynamical migration of labeling NPCs along RMS towards OB may be visualized on MRI.

    • 摘要: Objective To analyse clinical and cerebrospinal fluid cytological features of primary central nervous system lymphoma (PCNSL) with ependymal involvement and investigate the diagnostic value of cerebrospinal fluid cytology. Methods Clinical and radiological features of 4 cases of PCNSL were reviewed retrospectively. The findings in conventional cytology and immunocytochemistry of cerebrospinal fluid were analysed. Results All of the patients suffered from headache. Meningeal irritation signs were positive in all the 4 cases. Other clinical features were as follow: radiculoneuropathy in 2 cases, multiple cranial nerves paralysis in one case, hemiplegia in one case, and intermittent low-grade fever in 3 cases. Two cases died of cerebral hernia 2-4 months later after the onset. Lumber puncture was performed in 3 cases and intracranial hypertension was found in 2 cases. One case received ventricular drainage. Cerebrospinal fluid examination showed lymphocyte pleocytosis (4 cases) with elevated protein (4 cases) and lower glucose level (3 cases). The examination of cerebrospinal fluid found lymphocyte pleocytosis with remarkable atypical lymphoma cells in all of the cases. Among 3 patients received cerebrospinal fluid immunocytochemical studies, the lymphocytes were positive for CD19, CD20, CD79a and implied a Blymphocyte source. Brain magnetic resonance imaging (MRI) showed irregular enhancement of the ventricular wall with nodular periventricular and septal enhancement in part of the 4 cases and pituitary enhancement in one case. Two patients were diagnosed via biopsy of the brain, which showed nonHodgkin's lymphoma. The other two were diagnosed through cytology and immunocytochemical studies of cerebrospinal fluid. One case received positron emission tomography (PET) examination, which showed no evidence of extracranial involvement. Bone marrow biopsy in other patients were normal too. Conclusion Cytological and immunocytochemical studies of cerebrospinal fluid specimen should be stressed in the diagnosis of PCNSL. This report also emphasizes the importance of clinical and radiological findings in the diagnosis of this disease.%目的 分析室管膜型原发性中枢神经系统淋巴瘤(PCNSL)的临床及影像学特点,探讨脑脊液细胞学检测方法在诊断中的价值.方法 回顾4例室管膜型PCNSL患者临床诊断与治疗经过,分析其临床特点、影像学改变、脑脊液细胞学和免疫细胞化学染色结果.结果 4例患者平均发病年龄为44岁,发病至就诊时间13d~5个月.临床表现为头痛、脑膜刺激征,分别伴有脊神经根征(2例)、多组脑神经麻痹(1例)和偏瘫(1例);病程中有间断低热(3例).其中2例于发病2和4个月时死于脑疝.腰椎穿刺检查脑脊液压力(2例)、白细胞计数(4例)和蛋白定量(4例)升高,葡萄糖降低(3例).4例患者脑脊液细胞学检测均发现淋巴瘤细胞或异形淋巴细胞,免疫细胞化学染色大多数细胞呈现B细胞标记物阳性.头部MRI增强扫描第三和第四脑室、侧脑室壁异常强化,合并脑室周围强化病灶(2例)和鞍区病变(1例).PET扫描和骨髓穿刺检查未发现颅外或脊髓受累证据.结论 脑脊液细胞学和免疫细胞化学检测是诊断室管膜型PCNSL的重要方法.室管膜及脑室周围病变应考虑PCNSL的可能,尤其MRI增强扫描发现结节样强化者更应提高警惕.
