    摘要:

    目的: 探究天麻芎苓止眩片对自发性高血压模型鼠肾脏的作用及机制。方法: 购买SHR大鼠作为自发性高血压模型鼠,WKY大鼠作为正常血压对照鼠,大鼠适应性饲养后分为4组,1)Control组(WKY大鼠);2)Model组(SHR大鼠);3)Model+TXZT组(SHR大鼠+天麻芎苓止眩片);4)Model+Valsartan组(SHR大鼠+缬沙坦),3、4组分别以天麻芎苓止眩片、Valsarta灌胃干预,干预前后分别检测各组大鼠血压,分别使用ELISA和生化试剂盒检测TNF-ɑ、GSH,生化仪检测肾功能四项(肌酐、尿素氮、尿素和尿微量白蛋白),HE染色、TUNEL染色检测肾脏组织损伤程度和细胞凋亡情况,免疫荧光检测肾脏组织中NF-κB P65、p-P65、SIRT1和PGC-1ɑ表达情况。结果: 自发性高血压大鼠血清中TNF-ɑ含量升高,GSH含量降低,尿液中肌酐、尿素氮、尿素和尿微量白蛋白含量上升,使用天麻芎苓止眩片和Valsartan灌胃后,大鼠收缩压显著下降,舒张压有下降趋势但不明显,表明天麻芎苓止眩片和Valsartan具有降血压作用;大鼠血清中TNF-ɑ含量下降,GSH含量升高,大鼠尿液中肌酐、尿素氮、尿素和尿微量白蛋白含量下降,表明天麻芎苓止眩片和Valsartan可抑制炎症因子释放,抑制氧化应激,增强肾功能。自发性高血压大鼠肾脏组织中NF-κB P65、p-P65表达上升,SIRT1、PGC-1α表达下降,使用天麻芎苓止眩片和Valsartan干预后,NF-κB P65、p-P65表达下降,SIRT1、PGC-1α表达上升,表明天麻芎苓止眩片和Valsartan可提高SIRT1、PGC-1α表达,抑制NF-κB通路激活,从而抑制炎症反应。结论: 天麻芎苓止眩片可对自发性高血压大鼠肾脏起保护作用,机制为升高自发性高血压模型鼠肾脏中SIRT1、PGC-1α表达、降低NF-κB P65、p-P65表达,抑制炎症反应相关。

    Abstract:

    Objective: To investigate the effect and mechanism of Tianma Qiongling Zhixuan tablets on the kidneys of spontaneously hypertensive model mice.Method: SHR rats were purchased as spontaneously hypertensive model rats, and WKY rats were used as normal blood pressure control rats. After adaptive feeding, the rats were divided into four groups: 1) Control group (WKY rats); 2) Model group (SHR rats); 3) Model+TZZT group (SHR rats+Tianma Qiongling anti glare tablets); 4) The Model+Valsartan group (SHR rats+valsartan) was administered orally with Tianma Qiongling Zhixuan tablets and Valsarta for intervention in groups 3 and 4, respectively. Blood pressure was measured before and after intervention in each group of rats. ELISA and biochemical kits were used to detect TNF - α and GSH, and a biochemical analyzer was used to detect four renal function parameters (creatinine, urea nitrogen, urea, and urinary microalbumin). HE staining and TUNEL staining were used to detect the degree of kidney tissue damage and cell apoptosis, and immunofluorescence was used to detect the expression of NF - κ B P65, p-P65, SIRT1, and PGC-1 α in kidney tissue.Result: The levels of TNF - α in the serum of spontaneously hypertensive rats increased, while the levels of GSH decreased. The levels of creatinine, urea nitrogen, urea, and microalbumin in urine increased. After oral administration of Tianma Qiongling Zhixuan tablets and Valsartan, the systolic blood pressure of rats significantly decreased, while the diastolic blood pressure showed a decreasing trend but not significant, indicating that Tianma Qiongling Zhixuan tablets and Valsartan have a hypotensive effect; The content of TNF - α in rat serum decreased, while the content of GSH increased. The levels of creatinine, urea nitrogen, urea, and microalbumin in rat urine decreased, indicating that Tianmaqongling Zhixuan tablets and Valsartan can inhibit the release of inflammatory factors, suppress oxidative stress, and enhance renal function. The expression of NF - κ B P65 and p-P65 in the kidney tissue of spontaneously hypertensive rats increased, while the expression of SIRT1 and PGC-1 α decreased. After intervention with Tianma Qiongling Zhixuan Tablets and Valsartan, the expression of NF - κ B P65 and p-P65 decreased, while the expression of SIRT1 and PGC-1 α increased. This indicates that Tianma Qiongling Zhixuan Tablets and Valsartan can increase the expression of SIRT1 and PGC-1 α, inhibit the activation of the NF - κ B pathway, and thus suppress the inflammatory response.Conclusion: Tianma Qiongling Zhixuan Tablets can have a protective effect on the kidneys of spontaneously hypertensive rats, by increasing the expression of SIRT1 and PGC-1 α in the kidneys of spontaneously hypertensive model rats, reducing the expression of NF - κ B P65 and p-P65, and inhibiting inflammation related reactions.
