摘 要:目的:探讨雄蚕益肾方对雄性迟发性性腺功能减退症(LOH)大鼠睾丸组织细胞生物钟基因表达的影响。方法:48只8周龄雄性SD大鼠随机分为正常组,模型组,丙酸睾酮组,雄蚕益肾方低、中、高剂量组。模型组,丙酸睾酮组,雄蚕益肾方低、中、高剂量组大鼠腹腔注射480 mg/(kg·d)D-半乳糖(D-gal),连续注射56 d进行LOH造模,正常组大鼠每日腹腔注射相同体积生理盐水。造模成功后,雄蚕益肾方低、中、高剂量组分别给予10.4、20.8、41.6 g/(kg·d)体重剂量的雄蚕益肾方中药汤剂灌胃,每组每日均早、晚各灌胃1次;丙酸睾酮组大鼠肌注5.21 mg/(kg·d)体重剂量的丙酸睾酮,每周3次;正常组和模型组给予相同体积的蒸馏水灌胃;各组均连续操作28d。实验结束后,采血离心取上清液ELISA法检测睾酮(T)水平,取睾丸组织进行RT-qPCR、Western印迹分别检测BMAL1、NR1D1、PER2、CRY1、StAR、CYP11A1 mRNA表达量和蛋白表达水平。结果:模型组大鼠血清睾酮水平、睾丸组织BMAL1、NR1D1、PER2、CRY1、StAR、CYP11A1在mRNA表达量和蛋白表达水平均显著低于正常组(P<0.05);与模型组相比,丙酸睾酮组、雄蚕益肾方低、中、高剂量组大鼠血清睾酮显著升高(P<0.05),雄蚕益肾方高剂量组大鼠睾丸组织StAR mRNA表达量、CYP11A1 mRNA表达量和蛋白表达水平显著升高(P<0.05),雄蚕益肾方低、中、高剂量组大鼠睾丸组织StAR蛋白表达水平显著升高(P<0.05),丙酸睾酮组、雄蚕益肾方低、中、高剂量组大鼠睾丸组织BMAL1、NR1D1蛋白表达水平及PER2蛋白表达水平和mRNA表达量显著升高(P<0.05),雄蚕益肾方中、高剂量组大鼠睾丸组织BMAL1 mRNA表达量、CRY1蛋白表达水平显著升高(P<0.05),雄蚕益肾方低、中、高剂量组大鼠睾丸组织NR1D1 mRNA表达量显著升高(P<0.05),丙酸睾酮组、雄蚕益肾方中、高剂量组大鼠睾丸组织CRY1 mRNA表达量显著升高(P<0.05)。结论:雄蚕益肾方能上Objective:To investigate the effect of Xiongcan Yishen Formula(XYF)on the expressions of the clock genes in the testis tissue of the rats with late-onset hypogonadism(LOH).Methods:Forty-eight 8-week-old male SD rats were randomly divided into 6 groups,normal control,model control,testosterone propionate(TP),and low-,medium-and high-dose XYF.The LOH model was made in the later 5 groups of rats by intraperitoneal injection of D-galactose at 480 mg/kg/d for 56 successive days,while the normal controls were injected with the same volume of normal saline.After modeling,the rats in the low-,medium-and high-dose XYF groups were treated intragastrically with XYF at 10.4,20.8 and 41.6 g/kg/d,bid,respectively,those in the normal and model control groups with the same volume of distilled water,and those in the TP group intramuscularly with TP at 5.21 mg/kg/d,qd alt,all for 28 days.After treatment,the supernatant was obtained for measurement of the serum T level by ELISA,and the testis tissue collected for determination of the mRNA and protein expressions of BMAL1,NR1D1,PER2,CRY1,StAR and CYP11A1 by RT-qPCR and Western blot.Results:Compared with the normal controls,the rats in the LOH model control group showed significantly decreased serum T and mRNA and protein expressions of BMAL1,NR1D1,PER2,CRY1,StAR and CYP11A1(P<0.05).In comparison with the findings in the model controls,the T level was remarkably increased in the TP and XYF groups(P<0.05),the expressions of StAR mRNA and CYP11A1 mRNA and protein markedly up-regulated in the high-dose XYF group(P<0.05),and so was the expression of the StAR protein in the XYF and TP groups(P<0.05),those of BMAL1 and NR1D1 proteins and PER2 mRNA and protein in the high-dose XYF group(P<0.05),those of BMAL1 mRNA and CRY1 protein in the medium-and high-dose XYF groups(P<0.05),that of NR1D1 mRNA in the XYF and TP groups(P<0.05),and that of CRY1 mRNA in the medium-and high-dose XYF and TP groups(P<0.05).Conclusion:Xiongcan Yishen Formula could up-regulate the expressions of the clock genes i
