BACKGROUND: As a specially differentiated central nerve, optic nerve is once injured, retinal neurons are hard to restore and regenerate. As a result, visual function is lost permanently. Currently, an effective clinical treatment is not available. Due to the multi-directional differentiated potential of stem cells, their role in optic nerve protection and restoration following injury is becoming a hot research spot.OBJECTIVE: To review the classification and transplantation of stem cells in optic nerve protection study, as well as roles of stem cells transplantation in optic nerve protection and repair following injury.METHODS: The database of ISI Web of Knowledge platform was searched on computer from February 1994 to April 2009, with the key words "stem cells, optic nerve" in English. In the same way, the database of CNKI from February 1994 to April 2009 was also screened, with the key words "stem cells, optic nerve" in Chinese.RESULTS AND CONCLUSION: A total of 98 literatures related to stem cells in optic nerve protection and restoration after injury are collected, in which 23 papers are Chinese and 75 papers are English. The studies published earlier, repetitively and similarly are removed, and 38 papers which comply with the standards are involved into this review. Stem cells own the potential of self-renew physiologically, as well as potential of repairing the injuries. At present, most of the researches on stem cells in optic nerve protection and restoration after injury are represented in morphosis. How to implant stem cells safely and effectively and how to recover stable visual function still need our efforts. Stem cells derived from skin, peripheral blood, fat and other tissues are convenient to draw materials and are commendable subjects, we should study them deeply to make preferable use.

Objective To investigate the aesthetic relations and internal regularities in normal craniofacial stereoscopic architecture. Methods By means of computer aided three dimensional measurement and analysis, a study on morphological features and inter relations of the cranio orbitozygomatic maxilla structures of twenty youths with pretty facial appearance was carried out. Results There were remarkable differences between each craniofacial structure in different sexes, but the ratio indices that represented the inter-relations of different craniofacial structures were closely similar in both sexes. In the group of youths the asymmetry ratios between bilateral craniofacial structures were below 5 % , presenting the perfect symmetry feature. The asymmetry ratios and their standard deviations of the zygomas and angulus mandibulae were relatively large . The results suggested that these two characteristic parts which influence the whole appearance were easily changeable with different individuals. There were close co relations between coronal axis width and sagittal axis protrusion in main structures of craniofacial region. These relationships could sum up in linear regression equations. Conclusion There are internal aesthetic regularities of coordinative ratios and harmonious symmetry in normal three dimensional craniofacial architecture, which determines the pretty appearance of youths. These internal regularities and aesthetic principles should be considered in designing and performing craniofacial aesthetic plastic operation so as to get excellent surgical results.

N-carbamoylase is a part of hydantoinase operon which can transform N-carbamoylamino acid to corresponding ammo acids. The L-N-carbamoylase of Arthrobacter BT801, codied by the HyuC gene, is the rate-limiting and the only stereoselective enzyme. HyuC DNA fragment was amplified by PCR from the plasmid of pUC18-169. The target fragment was introduced into pPIC3. 5K plasmid to construct the pPIC3. 5K-hyuC expressing vector which was then transduced into Pichia pastoris GS115 cells after being linearized by BglⅡ digestion. Multi-copies insertion transformants were screened on G418 plates. The recombinant protein was proved to have biological activity of hydrolyzing N-carbamoylphenylalanine into phenylalanine through enzyme activity determination.

Objective To analyze the principle of the drug use ofMenghe PhysiciansMa-Peizhi by using the Traditional Chinese Medicine(TCM)inheritance support system.Methods The prescriptions for the commonly encountered diseases that used byMa-Peizhi were collected to build a database, and analyze by the unsupervised data mining methods, such as apriori algorithm, entropy clustering complex systems, from which we could get the frequency of the drugs, the association rules between drugs, the core drug combinations, and so on.Results Based on the analysis of 745 prescriptions, the most frequently used drugs were tuckahoe, chiretta, paenoiae alba, dried orangepeel and dioscoreae. The core drug combinations were “radix rehmanniae recen- salivia chinensis-ophiopogon root”, “teasel root-viscum album-achyranthes”, “menispermaceae-heracleum hemsleyanum michaux-gentiana macrophylla”, and “mulberry leaf-periostracum cicadae-the root of balloon flower”.
