From the Perspective of Cross-strait Mutual Recognition of Civil Judgment

随着两岸经贸往来的日益频繁，由此引发的法律纠纷也日益增多，两岸对司法互助的需求也日益迫切，尤其是民商事裁判的认可，不仅关系到法院的司法权威问题，也关系到当事人的权益能否最终得到落实。而两岸民商事裁判的认可制度，双方均依各自的单方规定，大陆地区出台了《最高人民法院关于人民法院认可台湾地区有关法院民事判决的规定》，台湾地区则依《台湾地区与大陆地区人民关系条例》进行调整。直至2009年《海峡两岸共同打击犯罪及司法互助协议》的签订，两岸方在民商事判决的认可方面取得了突破性的进展，但基于历史与政治的原因及两岸法律规定的不同，两岸在认可民商事判决的司法实践中仍存在不少问题。 本文除前言和余论外，主要分为...Along with the economic and trade exchanges have become increasingly frequent, resulting in the increasing number of legal disputes, the two sides of the judicial cooperation demand increasingly urgent, especially the civil official recognition, not only relate to the court 's judicial authority, but also related to the rights and interests of the parties could eventually be implemented.

瞬时弹性记录仪检测在脂肪肝筛查中的成功率及可靠性分析

【目的】瞬时弹性记录仪已被各大肝病学会指南推荐为评估肝脏脂肪变性及肝硬度首选的无创检测工具，本研究旨在分析影响其检测成功率及结果可靠性的因素。【方法】2018年中山大学附属第一医院职工体检自愿接受检查且资料完整者共788例，分析年龄、性别、体质指数、腰围、操作者经验等对检测成功率及结果可靠性的影响。【结果】对脂肪肝的检出率高于B超（55.9%vs.39.9%，P<0.001），总体检测失败及结果不可靠率仅为1.4%，检测成功率与性别无关，而随年龄、体质指数及腰围的增加而降低，LSMIQR/Median也随之呈现上升趋势，结果可靠性下降。随着操作次数增加，检测成功率及结果可靠性上升并趋于稳定，同一操作者进行超过300次检测可认为具备熟练操作经验。【结论】瞬时弹性记录仪的有效测量受增龄、体质指数、腰围等因素影响，固定操作者经短期培训后也能够获得很高的检测成功率及可靠的结果
