脑肿瘤

132 patients with PICH between June 1999 and June 2001 in the Tongji Hospital were included in the present study. Patients with hemorrhage secondary to traumatism, brain tumor, thrombolytic treatment, vascular malformation or with hemorrhagic infarction were excluded.

通过病史、神经系统体格检查和头部CT检查，并排除外伤性脑出血以及脑肿瘤、动静脉畸形、出血性脑梗塞、溶栓治疗等引起的继发性脑出血后，将1999年6月至2001年6月武汉同济医院住院的132例脑出血患者作为研究对象。

Methods One hundred patients (30 cases of uncertained cerebral angiopathy, 4 cases after embolization of angiodysplasia, 19 cases of cerebral trauma, 30 cases of cerebral tumour,17 cases of other diseases) underwent CT cerebral angiography.

10 0例病人(包括 3 0例疑颅内血管病变，4例血管畸形栓塞术后，19例脑外伤，3 0例脑肿瘤，其他 17例)进行颅脑CT血管造影检查，团注 2 。5～ 3ml/s ，延迟 17～ 2 0s ，凡脑肿瘤者 1～ 1.5min后再进行一次扫描。

Methods the diagnosis situation of 19 cases of cryptococcal meningitis who have been confirmed from 1980 to 2004 are analysed.results there are 17 misdiagnosis cases in 19 patients, of which 7 cases are tubercular meningitis,3 are viral meningitis,2 are brain tumor,1 is cerebral edema,1 is arachnoiditis of brain and 2 are others.conclusion misdiagnosis can be discreased by promoting learning about cryptococcal meningitis, examining the doubtful patients' csf frequantly and another examinations.

对本院1980—2004年确诊的19例新生隐球菌脑膜炎病人的诊断情况进行回顾分析。结果 19例确诊前有17例被误诊，其中误诊为结核性脑膜炎7例，脑肿瘤2例，病毒性脑膜炎3例，脑水肿1例，脑蛛网膜炎1例，红斑狼疮脑病1例，其他2例。结论提高对新生隐球菌脑膜炎的认识，对可疑病人多次做脑脊液墨汁涂片检查，或其他检查，可减少误诊。

Objective To evalue clinical significance of 1H-MRS in differentical diagnosis and clinical assessment between radiation-induced brain injury and tumor recurrence.

目的 探讨氢质子磁共振波普(1H-MRS)在脑肿瘤放射治疗过程中，对放射性脑损伤和脑肿瘤复发的评估及两者鉴别诊断中的临床意义。

Results:40 cases of stereotactic opera tions were successfully performed with the help of the robot. These operations i ncluded intratumoral irradiation, biopsy of brain lesion, evacuation of abscess or haemorrhagia, and removal of foreign body.

结果：临床成功应用机器人辅助完成脑立体定向手术40例，包括脑肿瘤内放疗、脑内病变活检、脑脓肿抽吸、脑内血肿排空、金属异物取出等手术。

The best quality of MRS is that the MRS is the only noninvasive and in vivo means in detecting the changes in metabolism state and special biochemical compounds in living animal and human body, and that make it possible for us to observe the physiological and biochemical characteristic of brain neoplasma ,and the development of neoplasma.

脑肿瘤是较为常见的肿瘤，其发病率占全身肿瘤的1.8％，其中以脑胶质瘤为最多，占43.7％，脑肿瘤的诊断及治疗一直是临床及基础研究的难点及热点，为了更好的了解胶质瘤的生物学特征，寻找有效的治疗方法，人们一直在寻求建立稳定安全的脑动物模型，大鼠C6胶质瘤具有与人脑胶质瘤相似的生物学特征，且模型较为稳定，被广泛用于肿瘤生物学及实验性治疗的研究中。

Malignant tumors indicate often lethal brain conditions, but even nonmalignant growths can preempt normal brain activity.

恶性脑肿瘤的手术适应症是确定无疑的，但是非恶性脑肿瘤也会生长而占据正常的脑组织结构影响脑的活跃功能。

This investigation was to establish a simplified culture system to isolate and passage brain tumor stem cells from human medulloblastoma, observe their proliferation and differentiation, and determine the expression of normal neural stem cell antigens, CD133 and Nestin, in BTSCs. METHODS: Eleven specimens of medulloblastoma were acutely dissociated and triturated into single cells without trypsin digestion.

本研究旨在利用简化的无血清培养基和悬浮培养方法，从人髓母细胞瘤中分离培养脑肿瘤干细胞，观察其在体外的增殖、分化，鉴定其特异性标志物CD133和Nestin的表达，验证肿瘤组织切片中CD133阳性细胞的存在，为脑肿瘤干细胞的进一步研究打下基础。

Nowadays the therapy of malignant brain tumors is still a challenge to neurosurgeons. One of the most important reasons is the initial mechanisms of brain tumors have never been well illustrated.

脑肿瘤，特别是恶性脑肿瘤的治疗目前仍是临床医生面临的一个难题，重要的原因之一是由于对脑肿瘤的发生发展机制尚不明了。

Methods Fourteen patients with brain tumors nearby the central sulcus and 6 normal volunteers underwent fMRI while they performing alternating unilateral finger-to-thumb opposition movements.

方法6名正常受试者和14名脑肿瘤患者采用双手交替对指运动模式行fMRI扫描，比较正常受试者与脑肿瘤患者脑激活的异同。
