摘 要 目的 研究茯苓酸对多囊卵巢综合征(PCOS)大鼠胰岛素抵抗的改善作用及机制。方法 将126只雌性大鼠按随机数字
表法分为空白组、PCOS 组、茯苓酸低剂量组(8.33 mg/kg)、茯苓酸高剂量组(33.32 mg/kg)、炔雌醇环丙孕酮组(阳性对照组,0.34
mg/kg)、重组大鼠高迁移率族蛋白 B1 蛋白(rHMGB1)组(8 μg/kg)和茯苓酸高剂量+rHMGB1 组(33.32 mg/kg 茯苓酸+8 μg/kg
rHMGB1),每组18只。除空白组外,其余各组大鼠均通过灌胃来曲唑混悬液的方式构建PCOS模型。建模成功后,每天给药1次,
持续4周。给药结束后,检测大鼠空腹血糖、空腹胰岛素水平及胰岛素抵抗指数(HOMA-IR),检测大鼠血清中促卵泡素(FSH)、促
黄体生成素(LH)、睾酮(T)水平及卵巢组织中白细胞介素1β(IL-1β)、肿瘤坏死因子α(TNF-α)水平,计算大鼠卵巢系数,观察大
鼠卵巢组织病理变化,检测大鼠卵巢组织中HMGB1、晚期糖基化终产物受体(RAGE)、磷酸化核因子κB p65(p-NF-κB p65)蛋白
表达情况。结果 与空白组比较,PCOS组大鼠卵巢组织病理损伤严重,空腹血糖、空腹胰岛素水平、HOMA-IR、卵巢系数升高,血
清中LH和T水平升高、FSH水平降低,卵巢组织中IL-1β、TNF-α水平及HMGB1、RAGE、p-NF-κB p65蛋白表达量升高,差异均具
有统计学意义(P<0.05)。与PCOS组比较,茯苓酸低、高剂量组和炔雌醇环丙孕酮组大鼠卵巢组织病理损伤减轻,空腹血糖、空腹
胰岛素水平、HOMA-IR、卵巢系数降低,血清中 LH 和 T 水平降低、FSH 水平升高,卵巢组织中 IL-1β、TNF-α 水平及 HMGB1、
RAGE、p-NF-κB p65蛋白表达量降低,差异均具有统计学意义(P<0.05);rHMGB1组大鼠对应指标的变化趋势与上述给药组相
反(P<0.05)。与茯苓酸高剂量组比较,茯苓酸高剂量+rHMGB1 组大鼠的上述指标变化均被显著逆转(P<0.05)。结论 茯
苓酸可能通过抑制HMGB1/RAGE信号通路改善PCOS大鼠胰岛素抵抗并抑制其炎症反应。

ABSTRACT OBJECTIVE To study the improvement effects of poria acid on insulin resistance in rats with polycystic ovary
syndrome (PCOS) and its mechanism. METHODS One hundred and twenty-six female rats were randomly separated into blank
group, PCOS group, poria acid low-dose group (8.33 mg/kg), pachymic acid high-dose group (33.32 mg/kg), ethinylestradiol
cyproterone group (positive control group, 0.34 mg/kg), recombinant rat high mobility group protein B1 protein (rHMGB1) group
(8 μg/kg), and poria acid high dose+rHMGB1 group (33.32 mg/kg poria acid+8 μg/kg rHMGB1), with 18 rats in each group.
Except for the blank group, the rats in all other groups were given Letrozole suspension intragastrically to construct the PCOS
model. After successful modeling, administration was performed once a day for 4 weeks. After medication, the fasting blood
glucose and fasting insulin levels, and insulin resistance index (HOMA-IR) were measured in rats; the levels of follicle-stimulating
hormone (FSH), luteinizing hormone (LH) and testosterone
