Part 4: Brain-derived neurotropic factor genetically modified olfactory ensheathing cells of the neonatal rat Objective To culture the olfactory ensheathing cells from the neonatal rat and modify them genetically by human Brain-derived neurotropic factor to increase the formation of neurophic factors. Methods The OECs were dissociated from the neonatal rat olfactory bulbs and purified with time-speed difference stick.

第四部分：脑源性神经营养因子基因转染新生大鼠嗅鞘细胞目的为提高嗅鞘细胞(Olfactory ensheathing cells，OECs)分泌脑源性神经营养因子(BDNF，Brain-derived neurotropic factor)的能力，探讨将外源性BDNF基因转染入OECs，为今后采用BDNF基因修饰的OECs移植治疗SCI奠定基础。

In the control animals,the GAP-43-LI nerve fibers were found mainly distributed in association with vascular plexuses,with minor extension into the parenchyma of the inner zone of the periarterial lymphocyte sheath.In the immunized animals,in addition to denser vascular plexuses,more fibers appeared in the outer zones of periarterial lymphocyte sheath,the marginal zone,and the red pulp,all known to be the sites of active immune response.

于对照动物，脾GAP-43-LI神经纤维主要分布于血管周围，少量伸入动脉周围淋巴鞘的脾基质中，而在免疫刺激的动物，不仅血管周围的神经纤维明显增多，动脉周围淋巴鞘外层、边缘区和红髓等免疫应答活跃的部位也出现许多神经纤维。

Results: 51 cases benign lesions at the thoracic inlet Include the trachea source lesion 8 cases,and apical lung hernia 3 cases and apical paraseptal blebs 2 cases and benign masses of thyroid 21 cases and esophagus diverticula 3 cases and lymph nodes tube...

结果51例胸腔入口区良性病变包括气管源性病变8例；肺尖疝3例，肺尖肺大泡2例；甲状腺良性肿块21例；食道憩室3例；淋巴结结核5例；血管性病变9例及神经鞘瘤1例。结论螺旋CT-3D和MPR对胸腔入口区良性病变的诊断和鉴别诊断是轴位扫描重要的补充手段。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.
