Objective To explore the method and significance for constructing three-dimensional visual model in bronchial tree of pig lung. Methods A set of pig lung specimen was infused with epoxy resin-lead oxide through the trachea,and then casted. The Mimics 15. 0 was used to construct three-dimensional visual model in bronchial tree of pig lung by utilizing CT data of the cast specimen. Results In the reconstructed three-dimensional visual model of bronchial tree,the three-dimensional effect was realistic. This model not only clearly showed each lobar direction and distribution of bronchial tree,but also allowed three-dimensional arbitrary scaling,shifting or rotating at any angle, and the diameter and distance of each lobar bronchus could be measured with the sofeware. Conclusion The three-dimensional visual model in bronchial tree of pig lung can be successfully reconstructed from the CT dataset by using related sofeware like Mimics,which can bring morphological reference to anatomical teaching and will be helpful to the development of virtual operation.

Scientific research capacity of college students is the direct embodiment in innova-tive qualities. Taking Zhaoqing Medical College as an example, by guiding students anatomy innova-tion practice activities including literature review, fund grant application, research experiments and achievement paper writing, and guiding the two team works such as Challenge Cup prize at the provincial level, the author elaborates on the fact that teachers and students building team is an effec-tive way to cultivate students' innovative ability, so as to make the positive exploration for establishing innovative talents of training system in higher vocational colleges.

Objective To evaluate the three-dimensional reconstruction and significance of arterial cast on chronic venous insufficiency of low extremity. Methods A set of specimen on chronic venous insufficiency of left lower extremity amputation residues was infused with epoxy resin-lead oxide through the femoral artery,and then casted. The CT data of the cast specimen was used to reconstruct 3D modal of ar-tery on chronic venous insufficiency of left lower extremity,using the volume rendering(VR) and maximum intensity projection(MIP). Re-sults The cast specimen and 3D reconstruction of chronic venous insufficiency of left lower extremity amputation residues could clearly dis-play distribution and run of lower extremity arteries,blood supply of lesion and local region embolism of small artery ( arteriole) . Conclusion The 3D modal of artery on chronic venous insufficiency of left lower extremity should provide morphological basis of exact etiology and perfect pathogenesis,also has a certain guiding significance of clinical diagnosis and treatment.
