Imbalanced free radicals and antioxidant defense systems in schizophrenia： A comparative study

Objective： To examine changes of blood oxidative-antiovidative level in schizophrenic patients and its relationship with clinical symptoms. Methods： Forty-six Chinese patients met DSM-IV （Diagnostic and Statistical Manual of Mental Disorders-iV） criteria for schizophrenia and fifty age- and sex-matched healthy controls were enrolled in the present study. Baseline psychiatric symptom severity was assessed with brief psychiatric rating scale, positive and negative syndrome scale on the blood draw day. Fresh blood samples were collected to measure levels of nitric oxide and lipid peroxide in plasma as well as activities of superoxide dismutase, catalase and glutathione peroxidase in red blood cells by spectrophotometric assays simultaneously. Results Comparison of the biochemical parameters indicated that the level of nitric oxide and lipid peroxide increased in patient group, which represented a positive correlation with positive scale scores; while the activities of three critical enzymes decreased and showed a negative linear correlation. Conclusion： This study showed that there are dysregulation of free radical metabolism and poor activities of the antioxidant defense systems in schizophrenic patients. Excess free radicals formation may play a critical role in the etiology of schizophrenia. Using antioxidants might be an effective therapeutic approach to partially alleviate or prevent the symptoms of schizophrenia.

Do cultural differences affect users’ e-learning adoption? A meta-analysis

The great advantages of e-learning have been recognized, and efforts have been made to promote e-learning adoption. Despite valuable research achievements from technology adoption, previous studies built their models from different perspectives. In this study, to offer a comprehensive research model on e-learning adoption, we integrated these models (ie, TAM, TPB and IDT) and included culture as a moderator. Based on 45 relevant empirical research, this study conducted a meta-analysis to explore key determinants of users’ attitude and behavioral intention to adopt e-learning. Combined with traditional technology acceptance theories and innovation diffusion theory, we developed a comprehensive model and explored the moderating role of culture. The results indicate that this integrated technology acceptance model can be applied to better understand e-learning adoption. The moderator analysis shows that the influence of subjective norms and self-efficacy on users’ behavior intention is more salient in the collectivistic culture, whereas perceived usefulness is more important for online learners in an individualistic culture.

论中国电影艺术风格特质

在中国电影发展中,在协调现代性视野和本土传统特色时,需要特别关注自身艺术风格的承传和发扬。东方艺术精神的抒情性、情景交融性、教化传统性、造型写意性等构建出中国电影本土艺术的风格走向。如何在现代背景中扬弃修正传统艺术精神,是需要我们思考的问题。     

衬底状态及热处理对Sm-Fe GMFs磁致伸缩性能的影响

采用IBS法在锡青铜衬底上溅射沉积Sm-Fe非晶态超磁致伸缩薄膜,研究衬底的表面状态和薄膜热处理对Sm-Fe薄膜磁致伸缩性能的影响.实验结果表明,锡青铜衬底状态对Sm-Fe超磁致伸缩薄膜磁伸性能有很大影响.样品经过200℃真空热处理后,100 mT内dλ/dH值从制备态Sm-Fe薄膜的0.71×10-3 T-1提高到2.48×10-3 T-1,薄膜低场磁敏性得到显著提高.
