The raw data was processed by using axial, coronal and double oblique multi-planar reformation; Images obtained were graded in terms of quality with a 5-point scale(5=excellent, 4=good, 3=fair, 2=poor, and 1=nondiagnostic). In grading image quality at axial MPR, The radiologic specialists focused on the subarcuate fossa, tendon of tensor tympani, facial recess, vestibular aqueduct and pyramidal eminence, In grading image quality at coronal MPR, attention was given to the scute, crista transversa, fenestra cochleae, lateral malleal ligament and snake eyes signature of cranial nerve, In the grading of the image quality at double oblique MPR, the radiologic specialists concentrated on the malleus, incus, stirrup bone, upper bony semicircular and aquaeductus fallopii, and then to implement statistical analysis. In order to choose the minimum tube current values and the maximum pitch that can satisfy the diagnosis request, image quality of axial, coronal and double oblique reformation images was compared with different tube current groups. 15 ears of volunteers were used to test the validity with the scanning parameter. Subsequently noise, MTF and dose length product were measured by phantoms in different tube current and pitch, the parameters obtained were compared and taken into statistics analysis.

According to the observation of the microstructure of small diameter lumber with scan electron microscope, there are many bordered pits of the radial trancheidal wall in the small-diameter Larch, and most of them have pit film. The resin is not only in resin canal, but also in some trancheid and ray parenchyma cells. The drying defects of small-diameter Larch lumbers were the most severe in consecution heating, fluctuating-heats 2h in between, and drying defects were nearly not observed in fluctuating-heats 6h. There is tylosis in the vessel of the heartwood of small-diameter Cathay poplar. The bordered pits of the radial trancheidal wall are dense, and the pits between vessels are alternate, most of them have pit film. Different collapse happened in all the small-diameter Cathay poplar lumbers. The collapse of small-diameter Larch lumbers was the most severe with consecution heating, fluctuating-heats 2h in between, the least with fluctuating-heating 6h.

Results: At 3, 7 days post-grafting, SC survived in the lesioned area, hippocampus and ventriculus lateralis. At 14 days post-grafting, SC were migrating along ependyma, meninges and blood vessels. In the area of corpus callosum, SC were arranged like chains. At 60 days post-grafting, the number of SC was decreased and the fluorescent mark of SC was weakened. At 90 days post-grafting, the survival cells were few.
