Objective To investigate the CTA, MRA and DSA in the primary liver cancers and the value of the perfor-mance. Methods 29 cases of primary liver cancer patients were diagnosed through comparative analysis of CTA, MRA and DSA in the diagnosis of primary liver cancer between the common and the differences to explore the full and effective ways so as to facilitate the clinical work in a more effective diagnostic tool. Results For 29 cases of liver cancer patients, both the detection rate and accuracy rate of MSCTA were significandy higher than MRA. Conclusion At this stage, the MSCTA has features of shortcut, convenience, high detection rate, which is the preferred method of examination and has higher value in clinical application.

【Objective】To devise the optimal method and the optimal water content for the storage of seeds of Aquilaria sinensis(Lour.) Gilg..【Methods】The seeds of Aquilaria sinensis(Lour.) Gilg.were stored in plastic bag,drying apparatus,wet sand and dry sand separately.And then the germination capacity of the seeds with different water content was detected at 4℃ and room temperature(30℃) in different time.【Results】The germination capacity of Aquilaria sinensis(Lour.) Gilg.decreased with the prolongation of storage time and with the decrease of water content.The seeds with water content being 9.34% and 7.35% had a higher germination capacity when stored at 4℃ for 35 days than that stored at room temperature.The fresh seeds stored in wet sand sprouted and the seeds stored in drying apparatus and dry sand had lower germination capacity and went mouldy.【Conclusion】Low temperature and moderate water content are benificial to the storage of the seeds of Aquilaria sinensis(Lour.) Gilg..

【Objective】To explore the long-term storage method for the seeds of Aquilaria sinensis(Lour.)Gilg..【Methods】The seeds of Aquilaria sinensis(Lour.)Gilg.with different water contents were preserved with liquid nitrogen for 55 days.And then the seeds were taken out to detect their germination capacity.The effect of cryopreservation methods on the germination capacity was also observed.【Results】The seeds with water content being 16.30% lost their germination capacity completely,the seeds with water content being 13.02% and 9.34% had a lower germination capacity,and the seeds with water content being 7.35% had a higher germination capacity.Quickly-frozen seeds had a higher germination capacity than the slowly-frozen seeds.【Conclusion】Cryopreservation with liquid nitrogen is suitable for the long-term preservation of the seeds of Aquilaria sinensis (Lour.)Gilg.with water content being 7.35%.

For the employment orientation of graduates in clinical medical major from three-year medical eduction,a curriculum system,which will be used to foster practical medical talented person for urban and rural communities,has been proposed in this paper.We will take measures,which not only further defines training target and requirement for the practical medical person from the short school system and guides students to alterate their ideological concept but also reconstructures new curriculum system and reforms teaching methods,to ensure the implementation of the training objectives
