0.05).CONCLUSION A similar MMN exists in guinea pigs and human.MMN has a process of development,differentiation and maturation with aging. Guinea pigs can serve as the candidate animal for MMN research.Comparing with ABR,MMN is more sensitive to evaluate the central auditory function.

Over the past twenty years, with the development of brain science, many acupuncture clinical researchers have used multidisciplinary methods and techniques to perform acupuncture clinical research on cerebrosis. Up to now, many achievements have been obtained such as expanding studied disease entities, standardizing methods, identifying objects, and developing more and more treatment methods and in-depth mechanism research.

Objective To evaluate the value of MSCT three-dimensional reconstruction postprocessing technique for operation of Scoliosis Orthomorphia. Methods 18 cases of scoliosis were performed with MSCT to be reconstructed by MPR, VRT. The three-dimensional reconstruction images displayed traverse, coronal and sagittal plane and measures data. Results By measuring data of 18 cases by means of the methods above, all parameters were accurate. Conclusion The three-dimensional reconstruction of MSCT makes up the disadvantages of X-ray. Any retrospective reconstruction can be done to the collected data. So patients can avoid being projected repeatedly and radiation can be reduced. Various parameters of the vertebrae concerning spine, spinal canal and the pedicle plane can be offered, providing reliable reference for pre-operations.

Objective To measure the volume of liver, the volume of mass of liver and the ratio of mass/righe lobe with the Volume Evaluation of MSCT, as a reference of liver function after resection of liver mass. Methods All cases were scanned and reconstructed with MSCT,and the volume of right liver, the volume of mass of right liver and its ratio were obtained with Volume Evaluation of MSCT. Results The method of measuring volume of liver with Volume Evaluation is simple and accurate. Conclusion It can be a important reference before and after resection of liver mass.

The essential factors of bone tissue engineering include seed cell,growth factor and scaffold material.The biological structure,biological function and preparation method of scaffold material,which is the key component in bone tissue engineering,have attracted our attention.An ideal scaffold material needs to have adequate mechanical strength,appropriate degradation speed,good biocompatibility,satisfactory availability,low price,et al.Common scaffold materials in bone tissue engineering mainly consist of inorganic matter,organic matter and natural derivatives.Silk fibroin which is extracted from silkworm protein fiber contains 18 kinds of amino acids.The glycine,alanine,serine are the main types in silk fibroin and its structure consisted of hydrogen bonding,hydrophobic bonding and crystalline region.Those special structures make it has good flexibility and tensile strength.Silk fibroin has other advantages incluing air permeability,moisture permeability and biodegradation.Besides silk fibroin with curing crystallization of diversification that easy to maintain biological affinity and form a special porous structure.Silk fibroin has good film and gel forming ability.Silk fibroin can bond with some other materials to further improve its physical and chemical properties.Silk fibroin can be formed into porous shape,membranous,gel and composite materials scaffold.The materials scaffold which based on silk fibroin has excellent mechanical performance,adjustable degradation speed,high biocompatibility and good osteogenesis performance,besides capability of loading cells,bioactive factors and drugs.In addition,silk fibroin which can be made into gel scaffold,porous scaffold,electrospinning fiber,and compound scaffold et al has three-dimensional porous and biological function for bone tissue engineering as a new choice and application prospect.

OBJECTIVE To explore whether auditory event-related potential (AERP)exists in rat and what its features are,and to set up a set of AERP recording technique. METHODS Ten normal juvenile and 10 adult rats were served as subjects. Each rat was anesthetized and recorded AERP with passive mode. The responsibility of AERPs between juvenile and adult rats was compared. Also,the responsibility of AERP between rats and normal humans was compared. RESULTS AERPs could be evoked with passive recording mode in rats. Although the latencies and amplitudes of juvenile rats were respectively shorter and lower than thoses of adult rats,there were no significance in statistics. The AERP waveform of rats was similar to that of humans essentially. However,compared to the humans,the responsibility and stability of AERP in rats were less satisfied. CONCLUSION A similar AERP exists in rat and human. AERP has a process of development,differentiation and maturation,which may accomplish in early age in rat. Rat can serve as the candidate animal for AERP research.

Objective To study the neuroelectrophysiological responsibility, mechanism and clinical application of auditory event-related potential (AERP) generated in bilateral auditory centers with ipsilateral and contralateral recordings. Methods 14 normal young adults were served as subjects. AERPs, including the responsibility, latencies, amplitudes and waveforms, were simultaneously recorded on ipsilateral and contralateral vertexes and analyzed. Results The latencies and amplitudes of AERPs did not show significicant difference statislically between ipsilateral and contralateral vertexes recordings. However, the responsibility of AERP recorded on ipsilateral vertex was more satisfied than that on contralateral vertex, which exhibited smoothing waves, discriminative wave peaks and little hetero-wave. Conclusion The origins of AERP in bilateral auditory centers were essentially symmetrical. Nevertheless, the responsibility of AERP recorded on ipsilateral vertex was more satisfied than that on contralateral vertex, which was related to the components of auditory subcortex, transmission of auditory nerve to bilateral centers and the contralateral inhibiting effect of medial olivo-cochlear system. The effects of multi-generation and multi-component of AERPs on the clinical application should be considered.
