1、上海交通大学硕士学位论文维生素D受体基因ApaⅠ多态性与终末期肝病患者骨代谢的关系姓名:陈琳申请学位级别:硕士专业:内科学(内分泌)指导教师:盛正妍20070501上海交通大学2007级硕士研究生学位论文颈BMD均相关(P<0.05),AA基因型L1-4及股骨颈的BMD显著高于aa型(P<0.05,P<0.05)。终末期肝病组中,骨量减少组ApaⅠ基因型与L1-4及股骨颈BMD均相关(P<0.05,P<0.01),Aa基因型L1-4的BMD高于aa型(P<0.05),AA基因型的股骨颈BMD高于Aa和aa型
2、(P<0.01,P<0.001);对照组中,ApaⅠ基因型与L1-4及股骨颈BMD均无明显相关性。(3)终末期肝病组及终末期肝病骨量减少组中,ApaⅠ基因型与BGP水平相关,AA基因型的BGP水平高于aa型(P<0.05);ApaⅠ基因型与PTH、血Ca、血P及uCa/Cr水平差异无统计学意义。结论:终末期肝病患者VDR基因ApaⅠ位点多态性与BMD及BGP水平均相关,ApaⅠ位点多态性与终末期肝病患者骨代谢存在相关性。关键词:受体,基因,骨密度,维生素D,肝性骨病II上海交通大学2007级硕士研究生学位论
