不同内膜准备方案在子宫内膜异位症患者冻融囊胚移植中的疗效观察 [PDF]
目的研究不同内膜准备方案对子宫内膜异位症(EMs)患者囊胚冻融移植(FET)妊娠结局的影响。方法回顾性分析EMs患者375个囊胚FET周期,按照子宫内膜准备方式分为:单纯人工周期组(HRT组,45个周期),促性腺激素释放激素激动剂降调节后人工周期组(GnRH-a+HRT组,121个周期)和自然周期组(NC组,209个周期)。比较3种内膜准备方案的囊胚FET妊娠结局。结果 3组EMs患者间年龄、不孕年限、基础抗苗勒管激素(AMH)和基础内分泌水平比较均无统计学差异(P>0.05 ...

妊娠期高血压是严重威胁围产期母婴健康的产科综合征,临床上主要表现为高血压、蛋白尿和水肿等,给母婴带来严重的不良影响[1,2]。目前关于妊娠期高血压的确切的发病机制尚不明确,但其可能与母体内某些性激素的代谢紊乱有关[3,4]。因此,探索妊娠期高血压发病的相关生物分子对临床诊断和早期干预具有重要的意义。本研究分析性激素水平对妊娠期高血压的诊断价值,为临床诊断及评估和预测提供参考 ...
