子宫动脉舒张早期切迹联合孕早期血脂、妊娠相关血浆蛋白A对子痫前期的预测价值

目的:探讨子宫动脉舒张早期切迹联合孕早期血脂、妊娠相关血浆蛋白A(PAPP-A)对子痫前期(PE)的预测价值。方法:选取100例PE孕妇为PE组,同期113例健康孕妇为健康组。比较两组孕妇早期血清血脂[血清总胆固醇(TC)、高密度脂蛋白(HDL)、甘油三酯(TG)、低密度脂蛋白(LDL)]、PAPP-A水平及子宫动脉舒张早期切迹指数;回归分析影响PE的因素,并构建NMLE模型,受试者工作特征曲线(ROC)分析其对PE的预测价值。结果:两组PE组孕妇早期血清TC、HDL、TG、LDL及PAPP-A水平高于健康组(P<0.05);左、右子宫动脉舒张早期切迹指数小于健康组(P<0.05)。回归分析显示,血清PAPP-A、TC、HDL、TG、LDL水平及左右子宫动脉舒张早期切迹指数均为PE的独立危险因素(P<0.05);构建NMLE预测模型为Log=-567.23+1.961×TC+0.975×HDL+1.002×TG+0.864×LDL-1.051×左切迹指数-1.226×右切迹指数+0.904×PAPP-A;ROC分析显示,其预测PE的曲线下面积(AUC)为0.754,特异度、敏感度分别为91.00%、55.75%。结论:子宫动脉舒张早期切迹联合早期血脂、PAPP-A对PE具有一定的临床预测价值,可协助预估孕妇PE风险。

Pathogenesis, diagnosis and treatment of cerebral fat embolism

In this study, we analyzed two cases of pure cerebral fat embolism and reviewed related literatures to explore the pathogenesis, clinical manifestations, diagnosis and treatment of cerebral fat embolism, improve the treatment efficiency and reduce the misdiagnosis rate. In our cases, patients fully returned to consciousness at the different times with good prognosis, normal vital signs and without obvious sequelae. For patients with the limb fractures, who developed coma without chest distress, dyspnea or other pulmonary symptoms 12 or 24 h post injury, cerebral fat embolism should be highly suspected, except for those with intracranial lesions, such as delayed traumatic intracerebral hemorrhage, etc. The early diagnosis and comprehensive treatment can improve prognosis.
