Methods: A collection of 34 patients with astrocytomas proved by surgery and pathology were examined by magnetic resonance imaging(MRI), with 26 cases of gradeⅠ-Ⅱ(low-grade) and 8 cases of grade Ⅲ-Ⅳ(high-grade). MR perfusion images were obtained with spin-echo echo planar imaging (SE-EPI) techniques. Expression of VEGF was examined by immunohistochemical method of streptavidin-biotin-peroxidase(SP). The vascular development was measured by micro-vascular density (MVD) which was immunostained with anti-factor Ⅷ-related antigen monoclonal antibody. Results: Both of the expression of VEGF and the angiogenesis in 34 cases of astrocytomas were significantly correlated to the maximum relative cerebral blood volume (Max rCBV) (r=0.604, P<0.001;r=0.625, P<0.001, respectively). The Max rCBV and the expression of VEGF, MVD in high-grade astrocytomas were significantly higher than that of in low-grade astrocytomas (t= 3.0, P=0.017; t=7.08, P=0.01;t=3.37,P=(0.011,) respectively). Conclusion: MR perfusion weighted imaging might be a valuable method in in vivo study of the angiogenesis of astrocytomas and evaluating their malignant degree and prognosis.展开更多

Through analyzing the features of image schema considered by the authors as embodiment, recessiveness, sedimentation, logicality, scientificity, and dependency to cognitive metaphors and reviewing the definition of embodied cognition, the paper argues that image schema is an integration of bodily property and mental property, and accordingly a core and inseparable concept of embodied cognition by bridging body and mind. Image schema can help to explain how abstraction and inference generate from body-environment interactions, thus making the theory of embodied cognition more persuasive and reliable.展开更多

In addition to having offensive and defensive skills, it also absorbs the Chinese classical philosophy, traditional Chinese meridian theory and theory of health keeping. Cultural connotation of Tai chi chuan helps harmonious campus culture and mental health education. After years of research, the theory and practice shows that ： health effects of tai chi chuan on college students have positive significance, including the physical health and mental health.展开更多

Practitioners of Traditional Chinese Medicine (TCM) used the theory as a reasoning tool to illustrate the Zang-Fu organs' physiological functions and the interaction among them.The exploration of how the theory of that spleen system is associated with earth was created may provide insights into how five-element theory is applied to TCM practice. METHODS: Using analogism as a method to explore the relationship between earth and spleen system inTCM. RESULTS: Chinese ancestors experienced and observed the features of earth from agricultural practice and used the knowledge for the explanation ofspleen system functions including physiological functions, pathological characteristics and for the treatment of related illnesses. CONCLUSION: The theory of the five elements in TCM is a kind of metaphor, which depends on observation and exploration of the natural world and experience of human beings.展开更多
