          摘   要  目的  研究大豆异黄酮对先兆流产大鼠的保胎作用及可能机制。方法  取雌鼠促情,与雄鼠交配、妊娠后随机分为正常组
         (纯化水灌胃,n=10)、模型组(纯化水灌胃,n=9)、阳性对照药组(黄体酮4 mg/kg,肌内注射,n=9)和大豆异黄酮低、中、高剂量组
         (25、50、100 mg/kg灌胃,n=10)。除正常组外,其余各组大鼠均于孕8 d以米非司酮+米索前列醇灌胃建立先兆流产模型。各组大
          鼠分别于孕1~7 d、孕9~12 d给药/纯化水,每天1次。孕14 d时,计算各组大鼠的保胎率,检测大鼠血清中β-人绒毛膜促性腺激
          素(β-HCG)、孕酮(P)水平,观察大鼠胎盘与蜕膜组织病理形态学变化并检测其细胞凋亡指数,检测胎盘组织中凋亡相关因子
         (Fas)、凋亡相关因子配体(FasL)、增殖细胞核抗原(PCNA)和肝素结合表皮生长因子(HB-EGF) mRNA及其蛋白表达,检测蜕膜
          组织中Fas、PCNA和HB-EGF mRNA及其蛋白表达。结果  模型组大鼠胎盘组织充血扩张明显,血管较少且形态不规则,可见大
          量严重基质水肿、炎症细胞浸润和铁胆黄素沉积。与模型组比较,大豆异黄酮各剂量组大鼠的保胎率,血清β-HCG、P水平,胎盘
          与蜕膜组织中PCNA、HB-EGF mRNA及其蛋白表达水平均显著升高(P<0.05),病理学变化显著改善;胎盘与蜕膜组织细胞凋亡
          指数,胎盘组织中Fas、FasL mRNA及其蛋白表达水平,蜕膜组织中Fas mRNA及其蛋白表达水平均显著降低(P<0.05),且大豆异
          黄酮的上述作用呈剂量依赖性(P<0.05)。结论  大豆异黄酮对先兆流产模型大鼠有保胎作用;其作用机制可能与下调母-胎界面
          Fas、FasL mRNA及其蛋白表达,上调PCNA、HB-EGF mRNA及其蛋白表达有关。

          ABSTRACT    OBJECTIVE  To  study  the  protective  effect  and  possible  mechanism  of  soybean  isoflavones  against  threatened
          miscarriage  rats.  METHODS  Female  mice  were  selected  to  promote  estrus  and  mate  with  male  mice. After  pregnancy,  they  were
          randomly divided into normal group (purified water, i.g., n=10), model group (purified water, i.g., n=9), positive control drug
          group (progesterone 4 mg/kg, i.m., n=9), low-, medium- and high-dose soybean isoflavone groups (25, 50 and 100 mg/kg, i.g.,
          n=10).  Except  for  the  normal  group,  the  rest  were  given  mifepristone+misoprostol  on  the  8th  day  of  pregnancy  to  establish
          threatened  miscarriage  model,  and  then  given  purified  water  or  drugs,  once  a  day,  on  days  1-7  and  9-12  of  pregnancy,
          respectively. At 14 days of pregnancy, the rates of fetal protection were counted. Serum levels of β-human chorionic gonadotrophin
         (β-HCG)  and  progesterone (P)  in  rats  were  detected.  Pathological  and  morphological  changes  in  rat  placenta  and  decidua  tissues
          were  observed,  and  the  apoptosis  indexes  of  cells  were  detected;  mRNA  and  protein  expressions  of  factor  of  apoptosis  related
         (Fas), factor of apoptosis related ligand (FasL), proliferating cell nuclear antigen (PCNA) and heparin binding epidermal growth
          factor (HB-EGF) were determined in placenta tissues, and mRNA and protein expressions of Fas, PCNA and HB-EGF in decidua
                                                              tissues  were  detected.  RESULTS  In  the  model  group,  the
