RESUMO

Objective To study the requirements for defibrillation protection testing and marking of the multi-parameter monitor to facilitate the manufacturer to understand related standards and design products rationally.Methods The background and principle were described for defibrillation protection testing of the monitor.The requirements of related standards were analyzed for defibrillation protection testing and marking,and the defibrillation protection flow was explored during the clinical application of the monitor.Results The multi-parameter monitor might be damaged in case of the monitor's deficiencies in the the defibrillation protection,even patient's failure in the defibrillation protection or death might occur,and the electrical shock could be caused also to medical staffs.Conclusion The defibrillation protection is of great significance for the multi-parameter monitor,and considerations have to be posed on standards requirements and the monitor's clinical application so as to decrease its use risks.

RESUMO

<p><b>OBJECTIVE</b>To observe the images of early lesions of condylar cartilage of osteoarthritic rats in synchrotron radiation diffraction enhanced imaging (DEI).</p><p><b>METHODS</b>The animal model of temporomandibular joint osteoarthrosis was established in rat following the method of partial resection of the joint disc. The changes of osteoarthritic condylar cartilage in different pathological stages were observed by DEI and compared with those in situ histopathological sections.</p><p><b>RESULTS</b>With DEI, straight and orbicular lines were detected in condylar cartilage 45 to 60 days after discs resection. The lines were confirmed by histopathology to be collagen degradation and tiny fissure formation inside the cartilage.</p><p><b>CONCLUSIONS</b>DEI is capable of imaging the early stages of pathological changes of excised condylar cartilage such as collagen degradation and tiny fissure formation, and this technique is of potential value to clinical application.</p>
