颞叶癫痫可导致神经系统胶质增生，突触后终端与胶质细胞之间形成突触，突触后终端的树突棘的形态学的变化引起突触结构的改变，与胶质细胞之间形成的突触为异位突触，引起海马内环路性质的变化，从而提高致痫性。

We introduced improved primary mixed glial culture and different-attachment method to isolate and purify the OPCs, the cells were proliferated in serum-free medium, flow cytometry and immunohischemistry methods were employed to estimate the purity of cultured OPCs. Their abilities of differentiation and expression of trophic factors were identified by RT-PCR and immunostaining. Several methods including TUNEL and MTT were adopted to estimate the protective effects of conditioned culture medium from oligodendrocyte lineage cells on the primary cultured cerebellar granule neurons. Intravitreal transplant of OPCs, combined with retrograde fluorescent labeling the superior colliculus and intraorbital optic nerve transection, were used to investigate the protective effects of OPCs on the axotomized RGCs in vivo. Intravitreal transplantof OPCs or NSCs on the newborn rats, and retinal transplant of OPCs on the young rats were performed, to observe the myelin formation in the retina at different stages after cellular transplantation. Optic nerve transection was carried out on some rats with myelinated retinae, to study the influence of myelination on the injuried RGCs.

为此，本研究采用改良的胶质细胞混合培养与差速贴壁方法获得大鼠OPCs，使用无血清培养基进行扩增、培养，用免疫组织化学和流式细胞技术对培养细胞的纯度进行鉴定，对少突胶质系细胞表达部分营养因子的情况进行检测；采用TUNEL、MTT等方法对少突胶质系细胞条件培养基对原代培养小脑颗粒神经元的保护作用进行检测；将OPCs移植入成年SD大鼠玻璃体内，利用上丘逆行荧光标记技术，观察眼内移植的OPCs对眶内视神经切断时的视网膜神经节细胞的保护作用及其持续时间；将OPCs或NSCs移植入新生和幼年SD大鼠玻璃体或视网膜内，观察不同时期视网膜内髓鞘形成与分布特点，分析髓鞘的超微结构，并观察眼内髓鞘形成对损伤神经节细胞的保护作用。

In order to explore the function of glia in the progress the experiment was performed both in presence of glia and in the absence of glia The mouse mesencephalic cells were exposed with MPP+ with different concentration. Iloprost was used to investigate whether it can prevent dopamine neuron from the neurotoxic of MPP~..

为了观察胶质细胞在其中的作用，将细胞分为未抑制胶质细胞和胶质细胞抑制组；将不同浓度的MPP~+加入体外培养的中脑多巴胺能神经元培养液中，并加入Iloprost来研究其对MPP~+所导致的神经毒作用是否有保护作用。

At histopathologic analysis, neuronal tumors are usually classified as pure neuronal cell tumors (gangliocytoma, Lhermitte-Duclos disease , central neurocytoma) and mixed neuronal-glial tumors (ganglioglioma, desmoplastic infantile ganglioglioma, dysembryoplastic neuroepithelial tumor, ganglioneuroma).

根据组织病理学的分析，神经元肿瘤通常被分为：单纯的神经元细胞肿瘤（神经节细胞瘤，Lhermitte-Duclos 病〔发育不良性小脑神经节细胞〕瘤），中枢神经细胞瘤）和混合性的神经元-胶质肿瘤（神经节神经胶质瘤，成结缔组织性婴儿节细胞胶质瘤，胚胎发育不良性神经上皮瘤，神经节瘤）。

The malignant growth of neuroepithelial cell will result in glioma with high invasiveness and rapid growth.

神经胶质细胞的恶性生长导致胶质瘤，胶质瘤侵袭性强、生长迅速。

Results: The findings on CT and MRI were as follows: 57 cases of Oligodendroglioma, 15 cases of Ganglioglioma , 5 cases of Dysembryoplastic neuroepithelial tumor , 3 cases of Pleomorphic xanthoastrocytoma .
