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.

The application of BP nerval network to failure diagnosis of hydraulic systems in construction machinery is studied. Through collection of the system data, derivation of eigenvectors and structure of classifiers, a learning algorithm is established on the basis of network training. Tests show that satisfactory results can be obtained by the nerval network.

The obtained composite scaffold materials must have great biocompatibility, which could influence neuraxon regeneration and structure. An evaluation of permeability in varying molecules was a key factor to determine input of nutritive materials and output of metabolic waste.

不论用哪些材料，所制成的复合支架都要具有生物相容性，这在宏观和微观上都影响神经轴突再生的能力和结构；对不同大小分子的渗透性是评估营养物质进入支架和代谢废物排出的关键性能；要清楚支架在脊髓水环境中的膨胀程度，使其保持在合适的位置而不压迫再生的神经。

The obtained composite scaffold materials must have great biocompatibility, which could influence neuraxon regeneration and structure. An evaluation of permeability in varying molecules was a key factor to determine input of nutritive materials and output of metabolic waste. Expansion of scaffold should be understood under spinal cord water environment, because the expansion might press regenerated nerve.

I think WHO grade I dysembryoplastic neuroepithelial tumor is the most likely diagnosis, but one would like to see isolated floating neurons in the microcysts in addition to the small oligodendrocyte-like cells and neuropil-like fibrillary matrix.

我考虑可能是WHOI级的DNT（胚胎发育障碍的神经上皮肿瘤）。但DNT中除了少突胶质细胞样的小细胞和神经毡样胶质纤维基质外，还应该见到微囊中漂浮的神经元。
