摘　　要：目的探究大黄素调节AMP活化蛋白激酶(AMPK)/硫氧还蛋白相互作用蛋白(TXNIP)/NOD样受体热蛋白结构域相关蛋白3(NLRP3)信号通路对子痫前期(PE)大鼠炎症反应的影响。方法通过皮下注射L-精氨酸甲酯(100 mg·kg^(-1))构建PE大鼠模型。将60只雌性大鼠随机分为对照组、模型组、大黄素组(40 mg·kg^(-1)大黄素)、Compound B10组(100 mg·kg^(-1) Compound B10)、大黄素+Compound B10组(40 mg·kg^(-1)大黄素+100 mg·kg^(-1) Compound B10),每组12只。对照组和模型组腹腔注射等量0.9%NaCl。收集24 h尿液,用考马斯亮蓝法测定总尿蛋白含量,用蛋白质印迹法检测AMPK/TXNIP/NLRP3信号通路蛋白水平。结果对照组、模型组、大黄素组、Compound B10组和大黄素+Compound B10组的总尿蛋白相对表达水平分别为(54.34±6.26)、(136.37±15.43)、(76.38±8.61)、(215.39±25.14)和(110.93±13.92)g·L^(-1),尿量分别为(10.59±0.92)、(15.38±1.49)、(11.51±1.13)、(21.49±2.50)和(14.71±1.49)mL,AMPK蛋白相对表达水平分别为0.63±0.06、1.57±0.18、0.81±0.09、2.34±0.23和1.38±0.15,TXNIP蛋白相对表达水平分别为0.33±0.04、0.79±0.08、0.49±0.10、1.13±0.12和0.82±0.09,NLRP3蛋白相对表达水平分别为0.46±0.05、0.83±0.09、0.56±0.07、1.25±0.14和0.78±0.08。模型组的上述指标与对照组、大黄素组、Compound B10组比较,大黄素+Compound B10组的上述指标与大黄素组比较,在统计学上差异均有统计学意义(均P<0.05)。结论大黄素可能通过抑制AMPK/TXNIP/NLRP3信号轴缓解PE大鼠炎症反应,从而改善胎盘损伤。Objective To explore the effect of emodin on inflammatory response in preeclampsia(PE)rats by regulating the AMP activated protein kinase(AMPK)/thioredoxin-interacting protein(TXNIP)/NOD-like receptor pyrin domain-containing protein 3(NLRP3)signaling pathway.Methods PE rat model was established by subcutaneous injection of L-arginine methyl ester(100 mg·kg^(-1)).Sixty female rats were randomly divided into control group,model group,emodin group(40 mg·kg^(-1)emodin),Compound B10 group(100 mg·kg^(-1)Compound B10),emodin+Compound B10 group(40 mg·kg^(-1)emodin+100 mg·kg^(-1)Compound B10),with 12 rats in each group.The control group and the model group were intraperitoneally injected with the same amount of 0.9%NaCl.The 24 h urine was collected,and the total urinary protein content was determined by Coomassie brilliant blue method.The protein levels of AMPK/TXNIP/NLRP3 signaling pathway were detected by Western blot.Results The total urinary protein levels of control group,model group,emodin group,Compound B10 group and emodin+Compound B10 group were(54.34±6.26),(136.37±15.43),(76.38±8.61),(215.39±25.14)and(110.93±13.92)g·L^(-1),respectively;urine volume were(10.59±0.92),(15.38±1.49),(11.51±1.13),(21.49±2.50)and(14.71±1.49)mL,respectively;AMPK protein levels were 0.63±0.06,1.57±0.18,0.81±0.09,2.34±0.23and 1.38±0.15,respectively;TXNIP protein levels were 0.33±0.04,0.79±0.08,0.49±0.10,1.13±0.12 and0.82±0.09,respectively;NLRP3 protein levels were 0.46±0.05,0.83±0.09,0.56±0.07,1.25±0.14 and0.78±0.08,respectively.The above indexes:Model group was compared with control group,emodin group and Compound B10 group,emodin+Compound B10 group was compared with emodin group,the differences were statistically significant(all P<0.05).Conclusion Emodin may alleviate inflammatory reaction in PE rats by inhibiting AMPK/TXNIP/NLRP3 signal axis,thereby improving placental injury.
