摘 要 目的 探究柠檬苦素对妊娠期糖尿病大鼠肾脏病变及糖代谢、炎症、氧化应激的影响及可能机制。方法 采用腹腔注射链
脲佐菌素法构建妊娠期糖尿病大鼠模型。将妊娠大鼠分为模型组(灌胃并尾静脉注射等体积生理盐水),柠檬苦素低、中、高剂量
组(灌胃 12.5、25.0、50.0 mg/kg柠檬苦素并尾静脉注射等体积生理盐水),联合组[灌胃 50.0 mg/kg柠檬苦素+尾静脉注射 2 mg/kg
c-Jun氨基端激酶(JNK)激活剂Anisomycin],每组12只;另取12只妊娠大鼠作为对照组(灌胃并尾静脉注射等体积生理盐水);每
天1次,连续14 d。末次给药后,检测空腹血糖(FBG)值,检测血清中空腹胰岛素(FINS)、白细胞介素1β(IL-1β)、IL-6、肿瘤坏死
因子α(TNF-α)水平,检测肾组织中超氧化物歧化酶(SOD)、丙二醛(MDA)、谷胱甘肽过氧化物酶(GSH-Px)、血尿素氮(BUN)、肌
酐(Cr)水平,观察肾组织病理变化,检测肾组织中JNK/核因子κB(NF-κB)信号通路相关蛋白的表达。结果 与对照组比较,模型
组大鼠肾组织出现肾小球萎缩、肾小管上皮细胞水肿等病理损伤;FBG、FINS、IL-1β、IL-6、TNF-α、MDA、BUN、Cr水平,HOMA-IR
和JNK、NF-κB p65蛋白的磷酸化水平均显著升高(P<0.05);SOD、GSH-Px水平均显著降低(P<0.05)。与模型组比较,柠檬苦素
各剂量组大鼠肾组织病变程度均减轻,上述指标均显著改善(P<0.05),且存在明显的量效关系(P<0.05)。与柠檬苦素高剂量组
比较,联合组大鼠肾组织病变程度相对加重,上述指标变化被显著逆转(P<0.05)。结论 柠檬苦素对妊娠期糖尿病大鼠肾脏病变
及糖代谢、炎症、氧化应激具有一定的改善作用,其机制可能与抑制JNK/NF-κB信号通路有关。

ABSTRACT OBJECTIVE To explore the effects of limonin on renal lesions, glucose metabolism, inflammation, and oxidative
stress in gestational diabetic rats and its possible mechanisms. METHODS The model of gestational diabetic rats was established by
intraperitoneal injection of streptozotocin. The diabetic rats were divided into the model group (intragastrical administration and tail
vein injection of equal volume of normal saline), limonin low-, medium-, and high-dose groups (intragastrical administration of
limonin, at doses of 12.5, 25.0 and 50.0 mg/kg, and equal volume of normal saline into the tail vein), and combination group
[intragastrical administration of limonin 50.0 mg/kg + tail vein injection of c-Jun N-terminal kinase (JNK) activator Anisomycin 2
mg/kg ], with 12 rats in each group. In addition, 12 pregnant rats were selected as the control group (intragastrical administration
and tail vein injection of equal volume of normal saline). They were given relevant medicine, once a day, for 14 consecutive days.
After the last administration, fasting blood glucose (FBG), the levels of fasting insulin (FINS), interleukin-1β (IL-1β), IL-6,
and tumor necrosis factor-α (TNF-α) in the serum were detected; the levels of superoxide dismutase (SOD), malondialdehyde
(MDA), glutathione peroxidase (GSH-Px), blood urea nitrogen (BUN), and creatinine (Cr) in the renal tissue were detected; the
pathological changes of renal tissue were observed; the expressions of proteins related to the JNK/nuclear factor- κB (NF- κB)
signaling pathway in the renal tissue were detected. RESULTS Compared with control group, in model group, the rats showed
pathological injuries in the kidney tissue, such as glomerular atrophy, edema of renal tubular epithelial cells; the levels of FBG,
FINS, IL-1β, IL-6, TNF- α, MDA, BUN and Cr, HOMA-
