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
