摘 要 目的 研究补肾强身片对多囊卵巢综合征(PCOS)模型大鼠的干预作用及机制。方法 将50只大鼠灌胃来曲唑混悬液(1
mg/kg,每天1次,连续21 d)复制PCOS模型。将造模成功的大鼠分为模型组、阳性对照组(炔雌醇环丙孕酮片0.2 mg/kg+盐酸二
甲双胍片230 mg/kg)和补肾强身片低、中、高剂量组(189、378、756 mg/kg),每组10只。另取10只未造模大鼠作为正常组。各组
大鼠给予相应药物干预,每天 1 次,连续 30 d。末次给药 24 h 后,检测大鼠血清中雌二醇(E2 )、睾酮(T)、促性腺激素释放激素
(GnRH)、促卵泡激素(FSH)和促黄体生成素(LH)水平,计算大鼠卵巢系数,观察大鼠卵巢组织病理形态学变化,检测大鼠卵巢组
织中磷脂酰肌醇 3 激酶(PI3K)、磷酸化蛋白激酶 B(p-Akt)、磷酸化哺乳动物雷帕霉素靶蛋白(p-mTOR)和葡萄糖转运蛋白 4
(GLUT4)的表达水平以及PI3K、Akt、mTOR、GLUT4 mRNA表达水平。结果 与正常组比较,模型组大鼠卵巢系数、卵巢囊性病变
评分均显著增加(P<0.05),血清中 T、GnRH、LH 水平均显著升高(P<0.05),血清中 FSH、E2水平和卵巢组织中 PI3K、p-Akt、p-
mTOR、GLUT4蛋白表达水平及PI3K、Akt、mTOR、GLUT4 mRNA表达水平均显著降低(P<0.05),卵巢组织中闭锁卵泡及无卵丘
的囊性卵泡数量增多,卵泡颗粒细胞层数减少。与模型组比较,补肾强身片中、高剂量组大鼠上述指标水平均显著逆转(P<
0.05),低剂量组上述大部分指标水平显著逆转(P<0.05),卵巢组织病变均不同程度改善。结论 补肾强身片可调节PCOS模型大
鼠性激素分泌水平,改善卵巢囊性病变,其作用机制可能与上调PI3K/Akt/mTOR、PI3K/Akt/GLUT4两条信号通路有关。

ABSTRACT OBJECTIVE To study the intervention effect of Bushen qiangshen tablet on polycystic ovary syndrome(PCOS)
model rats and its mechanism. METHODS Totally 50 rats were given letrozole suspension(1 mg/kg,once a day,for consecutive
21 d) instragastrically to induce PCOS model. Model rars were randomly divided into model group,positive control group
(Ethinylestradiol and cyproterone acetate tables 0.2 mg/kg+Metformin hydrochloride tables 230 mg/kg),Bushen qiangshen tablet
low-dose,medium-dose and high-dose groups(189,378,756 mg/kg),with 10 rats in each group. Another 10 healthy rats were
included in normal group. Each group was given the corresponding drugs,once a day,for consecutive 30 d. Twenty-four hours
after the last administration,serum levels of estrogen(E2 ),testosterone(T),gonadotropin-releasing hormone(GnRH),follicle-
stimulating hormone (FSH) and luteinizing hormone (LH) were measured. The ovary index was calculated,and pathological
changes of ovary were observed. The protein expressions of phosphoinositide 3-kinase(PI3K),phosphorylated protein kinase B(p-
Akt),phosphorylated mammalian target of rapamycin(p-mTOR)and glucose transporter 4(GLUT4)in ovary were detected,and
mRNA expressions of PI3K,Akt,mTOR and GLUT4 in ovary were detected. RESULTS Compared with normal group,ovarian
index and ovarian cystic disease score were significantly increased in model group(P<0.05),and serum levels of T,GnRH and
LH were significantly increased (P<0.05);serum levels of FSH and E2,protein expressions of PI3K,p-Akt,p-mTOR and
GLUT4,and mRNA expression of PI3K,AKT,mTOR and GLUT4 in ovarian tissue were all significantly decreased in the model
group (P<0.05);in ovarian tissue,the number of atresia
