式，有齿状的，也有非齿状的。最重要的一点是：前端切割器一定要锋利

Neurogenesis in DG could be induced to increase at a certain time window after global ischemia reperfusion. The accommodational mechanisms of neurogenesis were possibly related to the changes of hormones, neurotransmitters, neurotrophic factors and the micro-circumstances of the dentate gyrus after ischemia.

结论缺血性脑损伤可诱导海马齿状回神经元发生水平在一定时间窗内上调，其机制可能与缺血引起脑组织激素水平、神经递质、神经营养因子浓度发生变化以及齿状回局部微环境改变有关。

The expression of Bcl-2mRNA and P53mRNA in hippocampus after 16Hz, 130dB infrasound treatment In 1 day group, Bcl-2mRNA and P53mRNA were expressed lightly in CA1-CA3 areas in hippocampus and dentate gyrus. Blood vessels dilated lightly. In 7d group, Bcl-2mRNA and P53mRNA were more expressed in areas mentioned above. Dilation of capillaries and small vessels was more obvious. Bcl-2mRNA and P53mRNA were strong positive in endothelial cells of vessels. In 14d group, Bcl-2mRNA and P53mRNA expression was obviously increased in pyramidal cells of hippocampus and granular cells of dentate gyrus, showing deep blue staining. a The endothelial cells in some vessels were also strong positive for Bcl-2mRNA and P53mRNA. Dilation of capillaries and small vessels was lessened. In 21d group, Bcl-2mRNA and P53mRNA expression was decreased in pyramidal cells. In 28d group, little change about the expression and distribution of Bcl-2mRNA and P53mRNA was observed. Lots of Bcl-2mRNA and P53mRNA were scattered in cortex of temporal lobe around hippocampus and callosal gyrus area. Dilation of capillaries and small vessels was lessened obviously. The expression of Bcl-2mRNA and P53mRNA in hippocampus after 16Hz, 90dB infrasound treatment.

次声作用后Bcl-2mRNA和P53mRNA在海马的表达，16Hz、130dB次声作用1d组：两者在海马〓区和齿状回轻度表达，海马内血管轻度扩张；7d组：两者表达在上述区域较1d增多，微血管和小血管扩张较显，血管内皮细胞内可见呈强阳性表达的Bcl-2mRNA和P53mRNA；14d组：海马锥体细胞和齿状回颗粒细胞内Bcl-2mRNA和P53mRNA阳性表达明显增多，呈深兰色，在部分血管内皮细胞内两者强阳性表达，微小血管扩张状态较7d减轻；21d组：锥体细胞胞浆内Bcl-2mRNA和P53mRNA表达减弱；28d组：上述表达及分布与21d组相比无明显改变，海马周围颞叶皮层和扣带回区域亦可见大量散在分布的Bcl-2mRNA和P53mRNA表达，血管扩张状态已明显减轻。90dB次声作用1d-7d后，较对照组无明显变化，14d-21d后轻度表达，28d后，Bcl-2mRNA和P53mRNA表达较强。

Results VA and bone structures of the craniovertebral junction were clearly observed and measured in three-dimensional visualization. The exposure of dens was improved in one third condylectomy. However, the decision to perform condylectomy and its extent should be made based on relationship between abnormal dens and occipital condyle.

结果 三维可视化技术使枕颈结合处椎动脉和骨结构的三维构象得到清晰的观察和测量；入路中磨除1/3枕髁能改善齿状突的显露，但应结合病变状态下齿状突与枕髁等结构的关系决定是否磨除或磨除的范围。
