抑郁症的神经生化特征及进展 总被引:3,自引:1,他引:3
抑郁症神经生物化学方面的研究近年来发展很快。在经典的神经递质中5-羟色胺的减少及其受体的基因调控,去甲肾上腺素和多巴胺及其受体也有一定的变化。近年来特别注意了谷氨酸和γ-氨基丁酸及多种神经肽与抑郁症相关。目前发现的这些生物活性物质可能在特定的条件下与特定的中枢神经部位共同调控情绪及其表达。因此了解这些生物活性物质将对抑郁症的诊断与治疗及发病机制有进一步的认识。 相似文献

目的 通过总结8例脑生殖细胞瘤患者的脑脊液细胞学结果,探讨脑脊液细胞学在脑生殖细胞瘤诊断中的价值.方法 总结2006年1月至2009年6月我院脑脊液细胞学发现肿瘤细胞的8例脑生殖细胞瘤患者,分析其临床特点、影像学和脑脊液细胞学结果.结果 8例患者中男性7例,女性1例.年龄13~25岁,分别以多饮、多尿和少汗等内分泌症状或神经科症状起病.神经科症状包括:头晕、头痛、智能减退、精神行为异常、复视、双下肢无力、尿便障碍等.神经影像学可见鞍上区和(或)松果体区占位、脑室扩张、室管膜和软脑膜强化、神经根增粗强化等.脑脊液绒毛膜促性腺激素3.2~1087.0 mIU/ml.脑脊液细胞学8例均见肿瘤细胞,呈中等大小的圆形,核大,核仁明显,胞质丰富,胞质内可见较多空泡.背景间有小淋巴细胞为主的炎性反应.过碘酸Schiff染色肿瘤细胞胞质中见阳性颗粒.4例行免疫细胞化学染色,其中2例抗胎盘碱性磷酸酶阳性;2例行Ki-67染色,阳性细胞分别占12%和20%.细胞角蛋白和癌胚抗原染色等阴性.结论 脑生殖细胞瘤患者的脑脊液细胞学结果特征明显,结合细胞免疫化学可以明确其类型及脑脊液播散,在诊断脑生殖细胞瘤过程中起着重要作用.Abstract: Objective To investigate the value of the cerebrospinal fluid ( CSF ) cytology in diagnosis of intracranial germinomas by reviewing the outcomes of CSF cytology of 8 patients with intracranial germinomas. Methods Eight patients with positive CSF cytology at our clinic from January 2006 to June 2009 were reviewed. Conventional cytology and immunocytochemistry of CSF were performed. The relevant literature on the subject was reviewed. Results The patients, including 7 male and 1 female, developed endocrinological or neurological symptoms at the age of 13 to 25, and the typical neurological presentation included vertigo, headache, mental and behavior disorders, double vision and weakness of legs. The CSF cell count ranged from 0 to 300 leukocytes per cubic and elevated in 7 cases, typically lymphocytic inflammation. CSF level of human chorionic gonadotropin was 3.2-1087.0 mIU/ml, higher than the individual serum level. On CSF cytology studies, typical tumor cells of germinima were found, which had positive particles in cytoplasm on periodic acid Schiff stain. All presents had lymphocyte inflammation ( small lymphocyte predominant ). On immunocytochemical studies of CSF, the tumor cells were positive on placental alkaline phosphatase and Ki-67 stains. Conclusions CSF cytology is clinically useful for diagnosis of primary intracranial germinoma. Further clinical and cytological studies will be necessary for a better understanding of the biology of these tumors. 相似文献

<正>卒中是目前导致人类死亡的三大主要疾病之一,在我国,卒中发病率仍呈现逐年上升的趋势~([1])。急性缺血性卒中(acute ischemic stroke,AIS)约占全部卒中的80%~([2]),大动脉粥样硬化性缺血性脑卒中是脑梗死中最常见的类型。急性缺血性脑卒中患者时间窗内(4.5 h)静脉溶栓治疗方法是首选之一~([3]),尽管静脉溶栓对于所有严重程度的患者均有获益,但仍有70%以上卒中患者遗留残疾(modified 相似文献
