Results (1)The agger cells existed in 99% of the cases, the development of the agger cells in 9～16 years old children, and adult had no difference;(2) The morphology of agger cells differed widely, but its relationship to the anterior border of the middle nasal concha, bulla ethmoidalis and nasolacrimal canal was quite stable;(3) The upward pneumatization of the agger cells was not related to deviation of nasal septum, but closely related to the development of the frontal sinus;(4) The anterior nasosinusitis often influenced the agger cells and might result in hyperosteogeny.

结果 ①绝大多数病例（99%）有鼻丘气房，儿童（9～16岁）鼻丘发育与成人相比无差异性；②鼻丘形态变化很大，但与中鼻甲前端、筛泡和鼻泪管的关系是恒定的；③鼻丘向上气化程度与额窦发育关系密切，鼻中隔偏曲对其发育无明显影响；④前组鼻窦的广泛炎症易波及鼻丘，并可出现鼻丘骨质增厚。

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。

Methods:The nucleus pulposus of coccygeal vertebra was applyed to the L 4 and L 5 nerve roots of the rat without compression and the mechanical withdrawal threshold and thermal withdrawal latency were observed and CSEP of hindlimbs were recorded in 3 days, 1 week,2 weeks and 4 weeks respectively after surgery in order to show ...

The pilot study shows that the ammonia dissociation/synthesis reaction is inherently free of any potential side reaction problems, and also offers phase separation of products. The carrier of heat store is liquid. and is very interesting for long-term storage as it can be carried out at room temperature with no energy losses, Its theoretics energy storage density reachs 66.5kJ/mol, which outclasses sensible or latent heat storage. In comparison to other thermochemical energy storage, ATCES needs lower temperature in endothermic reaction(only 650℃), but It can produce over 550℃ high temperature stream in exothermic synthesiser. Furthermore, the heat store/recovery can change with adapt to the heat source/load automatically, and offers coninuous(24 h) production of heat, These advantages will see a rapid increase in the adoption of large-scale concentrating solar thermal power generation.

初步研究表明：采用氨基储能体系，储/释过程无副反应，且储能介质能自然发生相分离；储热载体为流体，并可在室温下长期无热损储存，理论储能密度达66.5kJ/mol，远高于显热或相变蓄热；与其它热化学储能相比，吸热反应温度低，仅需650℃，而放热反应可产生500℃以上的高温，能量的储/释流量可随热源/负荷自适应变化，且可全天供热，更适合作为聚光式大规模太阳能热力发电中的能量储存系统。
