Diabetic cardiomyopathy is one of the leading causes of heart failure and death in diabetic patients.There is classic evidence of ferroptosis in the development of diabetic cardiomyopathy,which proves that ferroptosis is correlated with the diabetic cardiomyopathy.Oxidative stress caused by excessive production of reactive oxygen species and loss of antioxidant capacity is considered to be the main mechanism leading to diabetic cardiomyopathy.As one of the key regulatory factors of oxi-dative stress,nuclear factor E2-related factor 2(NRF2)and its target gene play an important role in the prevention and treat-ment of diabetic cardiomyopathy.This article summarizes the mechanism of ferroptosis and the pathogenesis of diabetes cardio-myopathy,and expounds the relationship between them,and focuses on the molecular mechanism of NRF2 in the development of diabetic cardiomyopathy and its targeted treatment effect.

Objective To investigate the protective effect and mechanism of piperazine ferulate(PF)on acute kidney injury of rats with sepsis.Methods Twenty-four male Sprague Dawley rats were randomly divided into sham operation group,model group,low-dose PF group and high-dose PF group,with 6 rats in each group.The rats in the low-dose PF group and high-dose PF group were given 50 and 100 mg·kg-1 PF suspension by gavage every day for 7 days,respectively.The rats in the sham operation group and model group were given 9 g·L-1 sodium chloride solution(0.1 mL·kg-1)by gavage every day for 7 days.The rats in the sham operation group underwent cecal exploration and closed their stomachs without undergoing cecal ligation and perforation surgery.The rats in the model group,low-dose PF group and high-dose PF group underwent cecal ligation and perforation surgery to prepare the acute kidney injury models.At 24 hours after modeling,carotid artery blood of rats in each group was collected and the serum was separated.The levels of serum creatinine(Scr)and blood urea nitrogen(BUN)were measured by biochemical methods,and the levels of neutrophil gelatinase related lipid transport protein(NGAL),interleukin-6(IL-6),and procalcitonin(PCT)were measured by enzyme-linked immunosorbent assay.The rats in each group were executed by decapitation,then the kidneys were taken.The pathological changes of the kidney tissues were observed by hematoxylin-eosin(HE)staining.The relative expression levels of nuclear factor-κB(NF-κB),Toll-like receptor 4(TLR4)and NOD-like receptor thermal protein domain associated protein 3(NLRP3)in renal tissues were detected by Western blot method.Results The levels of Scr,BUN and serum NGAL,IL-6 and PCT of rats in the model group and low-dose PF group were significantly higher than those in the sham operation group(P＜0.05).The levels of Scr and serum PCT of rats in the high-dose PF group were significantly higher than those in the sham operation group(P＜0.05);there was no statistically significant difference in the levels of BUN and serum NGAL and IL-6 of rats between the high-dose PF group and the sham operation group(P＞0.05).The levels of Scr,BUN and serum NGAL,IL-6 and PCT of rats in the low-dose PF group and high-dose PF group were significantly lower than those in the model group(P＜0.05).The levels of Scr,BUN and serum NGAL,IL-6 and PCT of rats in the high-dose PF group were significantly lower than those in the low-dose PF group(P＜0.05).HE staining showed that there were no significant abnormal changes in the renal tissues of rats in the sham operation group.The renal tubular epithelial cells of rats in the model group showed significant swelling and degeneration,with a large amountof red staining in the cytoplasm;the renal tubular had congestion,degeneration,and necrosis,with a large number of inflammatory cells infiltrating the lumen,and cell proliferation in the mesangial-capillaries space.In the low dose PF group,some renal tubular epithelial cells of rats showed mild to moderate swelling,some renal tubular epithelial cells showed degenera-tion and necrosis,and no significant infiltration of inflammatory cells was observed.The renal tubular epithelial cells of rats in the high-dose PF group showed mild swelling,without significant degeneration,necrosis and inflammatory cell infiltration.The levels of TLR4,NF-κB and NLRP3 protein in renal tissues of rats in the model group and low-dose PF group were significantly higher than those in the sham operation group(P＜0.05).The level of TLR4 protein in renal tissues of rats in the high-dose PF group was significantly higher than that in the sham operation group(P＜0.05);there was no statistically significant difference in the levels of NF-κB and NLRP3 protein in the renal tissues of rats between the high-dose PF group and sham operation group(P＞0.05).The levels of TLR4 and NLRP3 proteins in the renal tissues of rats in the low-dose PF group and high-dose PF group were significantly lower than those in the model group(P＜0.05);the level of NF-κB in renal tissues of rats in the high-dose PF group was significantly lower than that in the model group(P＜0.05);there was no statistically significant difference in the level of NF-κB in renal tissues of rats between the low-dose PF group and model group(P＞0.05).The levels of TLR4 and NLRP3 proteins in tissues of rats in the high-dose PF group were significantly lower than those in the low-dose PF group(P＜0.05);there was no statistically significant difference in the level of NF-κB in renal tissues of rats between the high-dose PF group and low-dose PF group(P＞0.05).Conclusion PF intervention can effectively
