Abstract:

Objective To evaluate whether 6-gingerol(6G)can inhibit fibrosis and improve the cardiac and renal function and in rats with cardiorenal syndrome. Methods In the in vitro experiments of this study, the incorporation of isotope-labeled amino acids was used to detect the intervention of 6-gingerol on normal rat kidney-49F (NRK-49F) and normal rat kidney-52E (NRK-52E) cells. 68 male SD rats weighing 200 ~ 250 g were used to establish a rat model of cardiorenal syndrome by ligating the left anterior descending coronary artery and performing 5/6 nephrectomy. The rats were randomly divided into a control group, a model group, a low dose 6-gingerol group (6 mg/kg), a high dose 6-gingerol group (30 mg/kg), and a losartan potassium group (20 mg/kg). The 6-gingerol group received intraperitoneal injection of 6-gingerol, while the control group and model group received intraperitoneal injection of an equal amount of physiological saline. The losartan group received oral administration of losartan potassium for a total of 6 weeks. After successful modeling, blood samples were taken for biochemical and cardiac ultrasound examinations. After the experiment, blood, heart, and kidney samples were taken for Masson, immunohistochemistry, and Western blot. Results 6-gingerol 20 μmol/L can reduce NRK-49F collagen synthesis and inhibit NRK-52E protein synthesis. Biochemical results showed that the serum creatinine, urea nitrogen, and brain natriuretic peptide (BNP) levels of rats in the low and high dose 6-gingerol groups and the losartan group were all reduced, with high dose 6-gingerol groups and losartan group showing the most significant decrease (P < 0.05). Echocardiographic parameters showed that the 6-gingerol group and losartan potassium group improved cardiac contractile function and ventricular remodeling in rats (P < 0.05). Masson staining and Western Blot showed renal collagen deposition, with reduced expression of collagen I and α-SMA (P < 0.05). Immunofluorescence showed a decrease in the expression of renal collagen deposition I, α-SMA, and TGF-β1 (P < 0.05). Conclusion 6-Gingerol may improve the cardiac and renal function and renal fibrosis in rats with cardiorenal syndrome.
