          摘  要  目的  探讨左归丸胚胎期干预对妊娠糖尿病孕鼠子代糖耐量的影响及机制。方法  将孕鼠随机分为空白组、模型组、阳性
          对照组(甘精胰岛素)和左归丸低、中、高剂量组(4.725、9.45、18.9 g/kg),除空白组外,其余各组孕鼠腹腔注射链脲佐菌素制备妊娠
          糖尿病模型,妊娠6~18 d时各组孕鼠灌胃相应药物和蒸馏水,每日1次。子鼠出生21 d时,记录体重和体长,通过糖耐量试验计
          算曲线下面积(AUC)。子鼠出生22 d时,检测空腹血糖(FBG)和空腹胰岛素(FINS)、胰岛素敏感指数(ISI)、稳态模型评估胰岛素
          抵抗指数(HOMA-IR),观察胰腺组织形态结构;运用串联质谱标签蛋白质组学分析胰腺组织的蛋白谱,并检测载脂蛋白 A1
         (ApoA1)、溶质载体家族27成员1(Slc27a1)、激肽原1(Kng1)、钠钾ATP酶α2亚基(Atp1a2)、溶质载体家族7成员5(Slc7a5)、溶质
          载体家族3成员2(Slc3a2)、胆汁酸辅酶A:氨基酸N-酰基转移酶(Baat)、真核翻译起始因子2亚基γ(Eif2s3)蛋白及mRNA表达水
          平。结果  与模型组比较,阳性对照组和左归丸中剂量组子鼠体重、体长、ISI均显著增加/升高(P<0.05),糖耐量和胰岛细胞增生
          均明显改善,AUC、FBG、FINS、HOMA-IR均显著降低(P<0.05)。左归丸胚胎期干预妊娠糖尿病孕鼠子代的潜在靶蛋白有88个,
          涉及过氧化物酶体增殖物激活受体(PPAR)、环磷酸鸟苷-蛋白激酶G(cGMP-PKG)、脂肪消化和吸收、胆汁分泌等多条通路,与糖
          代谢和胰岛素抵抗等关系密切的蛋白主要有ApoA1、Slc27a1、Kng1、Atp1a2、Slc7a5、Slc3a2、Baat、Eif2s3。其中,与模型组比较,左
          归丸中剂量组孕鼠子代胰腺组织中 Slc7a5、Slc3a2、Baat 蛋白及 mRNA 表达量均显著上调(P<0.05),ApoA1、Slc27a1、Kng1、
          Atp1a2、Eif2s3蛋白及mRNA表达量均显著下调(P<0.05)。结论  左归丸胚胎期干预能改善GDM孕鼠子代的血糖水平和胰腺病
          理形态,其机制可能与上调 PPAR、cGMP-PKG、脂肪消化和吸收、胆汁分泌等通路中的 Slc7a5、Slc3a2、Baat 表达,下调 ApoA1、
          Slc27a1、Kng1、Atp1a2、Eif2s3表达有关。

          ABSTRACT   OBJECTIVE  To  explore  the  effect  and  mechanism  of  embryonic  intervention  with  Zuogui  pill  on  the  glucose
          tolerance  in  offsprings  of  pregnant  rats  with  gestational  diabetes  mellitus.  METHODS  Pregnant  rats  were  randomly  divided  into
          blank  group,  model  group,  positive  control  group (insulin  glargine),  Zuogui  pill  low-,  medium-  and  high-dose  groups (4.725,
          9.45,  18.9  g/kg).  In  addition  to  the  blank  group,  streptozotocin  was  injected  intraperitoneally  to  establish  a  gestational  diabetes
          mellitus rat model. From day 6 to day 18 of pregnancy, each group was given relevant medicine and distilled water intragastrically,
          once  a  day. After  21  days  of  birth,  the  body  weight  and  body  length  of  offsprings  were  recorded,  and  the  area  under  the  curve
         (AUC)  was  calculated  through  a  glucose  tolerance  test.  After  22  days  of  birth,  fasting  blood  glucose (FBG),  fasting  insulin
         (FINS) levels in serum, insulin sensitivity index (ISI), and homeostasis model assessment of insulin resistance (HOMA-IR) were
          measured,  and  the  morphological  structure  of  pancreatic  tissue  was  observed.  The  protein  spectrum  of  pancreatic  tissue  was
          analyzed  by  tandem  mass  tag-based  proteomics,  and  protein  and  mRNA  expression  levels  of  apolipoprotein A1(ApoA1),  solute
          carrier family 27 member 1 (Slc27a1), kininogen 1(Kng1) and sodium/potassium-transporting ATPase subunit alpha 2 (Atp1a2),
          solute  carrier  family  7  member  5 (Slc7a5),  solute  carrier  family  3  member  2 (Slc3a2),  bile  acid-coenzyme  A:  amino  acid  N-
          acyltransferase (Baat), eukaryotic translation initiation factor 2 subunit gamma (Eif2s3) were detected. RESULTS Compared with
          the  model  group,  the  body  weight,  body  length  and  ISI  of  offsprings  in  the  positive  control  group  and  Zuogui  pill  medium-dose
                                                             group  were  significantly  increased  (P<0.05),  while  the
