Summary: An early embryo co-culture system with human decidual stromal cells was established to study its effect on early embryonic cleavage and growth in vitro. Three hundred and eight 2-cell mouse embryos were co-cultured with human decidual stromal cell monolayer in MEM+0. 4 % bovine serum albumin (BSA) and 163 embryos cultured in MEM+15 % FCS alone as control. Among the mouse 2-cell embryos co-cultured with human decidual stromal cells, 72.73 % developed to the morula stage and 67.21 % cavitated to blastocysts with 59. 74 % hatching, as compared with 61. 34 % to morula stage, 48. 47 % to blastocysts and none hatching in the controls, respectively. Co-cultured embryos cleaved slightly faster than controls and showed no or less fragmentation than those in the control. These results suggested that human decidual stromal cells can support early embryonic development and yield a reasonable number of embryos with good quality up to blastocyst stage.

目的:研究新西兰兔心肌缺血后血清中心型脂肪酸结合蛋白(heart-type fatty acid-binding protein,H-FABP)的动态变化,以及中药桂枝汤复合方剂的干预作用。方法:将24只兔随机分为正常组、模型组、药物组,每组8只。药物组用桂枝汤复合方剂(6g·kg^(-1)·d^(-1))灌胃14d,正常组和模型组给予等量生理盐水灌胃14d。制作急性心肌缺血模型(药物组和模型组),正常组只穿线不结扎。采用结扎左冠状动脉前降支的方法复制心肌缺血模型。ELISA法检测血清H-FABP的含量,彩色多普勒超声心动图观察心脏射血分数(EF)。结果:与正常组相比,模型组结扎后30min H-FABP浓度开始升高,4h达高峰,6h开始下降(P<0.05);与模型组相比,药物组结扎后各时间点H-FABP含量均降低,结扎后6h心脏射血分数增高(P<0.05)。结论:血清H-FABP含量随心肌缺血时间有动态变化,中药桂枝汤复合方剂的预防应用可以降低血清H-FABP含量,改善心功能状态。
