The purpose of this study was to evaluate the renal protective effect of Qizhi Zhenwu Decoction on rats with DOCA salt hypertension and its influencing mechanism. In this study, the left kidney of rats was excised, and deoxycorticosterone acetate (DOCA) was injected under the epidermis, and a rat model of DOCA salt hypertension was made. They were then randomly divided into five groups: sham group, model group, Spironolactone group (Spi), QZZWD low-dose group (QZL), and QZZWD high-dose group (QZH), each group containing 7 rats. Several physiological measurements were done as follows: After two weeks of drug intervention, the blood pressure of mice was measured by tail sleeve method. Reactive oxygen species (ROS) were determined by fluorescence staining. Blood urea nitrogen and creatinine were detected by intelligent biochemical analyzer. Urine protein was detected by biochemical kit; The gene expression levels of NOX2, p47phox, NF-KB-p65, TGF-, TNF- and IL-6 were detected by western blotting. Compared with the sham operation group, the DOCA salt group showed obvious advantages compared with the model reference group in the gene expression levels of urinary protein, constriction pressure, urea nitrogen, creatinine, ROS and TGF-β, NOX2, P-NF-KB-P65, p47phox, TNF-αand IL-6 (p<0.05). QZZWD may maintain renal function by restricting NOX2/ROS/NF-KB signaling channels.
