Introduction: Most cochlear implants are currently compatible with magnetic resonance imaging(MRI) up to 3 ***, this does not completely eliminate the risk of serious accidents. Implant displacements and other adverse events with compatible implants have been reported in the *** reports: Among the six patients who had MRI after receiving implants at our center, we report three cases with adverse events related to the examination. The first case was complicated by magnet displacement with partial demagnetization. The second case showed total demagnetization, which necessitated removal and reimplantation of the implant. The third case involved severe pain sensation which disrupted the MRI scan. The smallest artifact was found with 3D MRI angiography, and largest artifact was found with diffusion and T2 ***: Moving the patient into the MRI apparatus must be supervised by an otorhinolaryngology specialist or an experienced radiologist. It is important to consider the magnetic field directions, so that angle between the implant magnetic fields and the MRI B0 always remains less than or equal to 90°. In addition, we recommend the use of an "arrow drawing" to facilitate the orientation of the magnetic field directions. Furthermore, to prevent magnet displacement, we recommend systematic use of a protective splint in addition to bandaging.

作者： Ying sophie Huang Frank M.Song Yizhong Wang College of Economics Zhejiang University School of Economics and Finance University of Hong Kong

This paper investigates how a firm＇s characteristics restrict the influence of monetary policy changes on its investment behavior. Focusing on China＇s listed companies for a sample period from the first quarter of 2002 to the first quarter of 2011, we find that quantity- oriented and price-based monetary policies have heterogeneous impacts on corporate investment behavior, but the influence of monetary policies is constrained by the liquidity, inventory, size and asset-liability ratio of a firm. Firms with higher liquidity, lower inventory level and lower asset-liability ratios are less sensitive to the impact from two kinds of monetary policies. The larger the size of the firm, the less it is subject to influenee from quantity-oriented monetary policy; it responds more to price-based monetary poliey. The policy implication is that the monetary authorities should pay attention to the importance of policy-making based on the monetary demand of mieroeconomie entities.

Objective: To screen and evaluate the active constituents of Chinese medicinal herbs as potent inhibitors of Cdc25phosphatase. Methods: The affinity chromatography purified glutashione-S-transferase/Cdc25A phosphatase fusion protein and Cdc2/cyclin B from the extracts of starfish M phase oocytes are used as the cell cycle-specific targets for screening the antimitotic constituents. We tested 9 extracts isolated from the Chinese medicinal herbs and vegetables including the agents currently used in cancer treatment by measuring the inhibition of Cdc25A phosphatase and Cdc2 kinase activity. The antitumor activity of the extracts was also evaluated by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay and flow ***: Cdc25A inhibitory activity and antitumor activity are detected in the extracts isolated from three Chinese medicinal herbs Agrimonapilosa; Herba solani lyrati; Galla chinesis. Conclusion: We found three extracts isolated from Chinese medicinal herbs have potential inhibitory activity of Cdc25 phosphatase using a highly specific mechanism-based screen assay for antimitotic drug discovery.
