ABSTRACT
Objective Taking Sortilin as the entry point,this study aims to explore the mechanism of vascular calcification in chronic renal failure(CRF)and explore the influence of Sanqi on Sortilin,TLRs and vascular calcification,and to provide an effective method for clinical reduction of cardiovascular events in CRF.Methods Thirty-six male SD rats were randomly divided into normal group,model group,low-,medium-and high-dose Sanqi group and calcitriol group,with 6 rats in each.The replicative CRF vascular calcification rat model was fed with adenine combined with high phosphorus diet.Aortic calcium salt deposition,serum creatinine(Scr),urea nitrogen(BUN),blood calcium(Ca),blood phosphorus(P),total cholesterol(TC),triglyceride(TG),TLRs and Sortilin protein in aorta and inflammatory factors were detected.Results In the model group,renal fibrosis was obvious and many adenine crystals were found in renal interstitium.Large deposits of calcium salts were found.Renal fibrosis and calcium salt deposition were alleviated in different degrees in all treatment groups.Compared with those in the normal group,the level of BUN,Cr,P,TG,TC,IFN-γ,IL-6,IL-10 and IL-17A in the serum of the model group was ascended(P<0.01),while the level of Ca was descended(P<0.01).Compared with those in the model group,the level of BUN,Cr,P,TG,TC,IFN-γ,IL-6,IL-10 and IL-17A in the serum of rats in the Sanqi medium and high dose group and calcitriol group was significantly decreased(P<0.01),and the contents of Ca were significantly increased(P<0.05 or P<0.01).Compared with those in the normal group,the protein expression of BMP2,RUNX2,Sortilin,TLR7 and TLR9 in aortic tissue of rats in the model group was elevated(P<0.01),while the protein expression of SM22α was declined(P<0.01).Compared with those in the model group,the protein expression of BMP2,RUNX2,Sortilin,TLR7,and TLR9 in the low-,medium-,and high-dose Sanqi group and calcitriol group was decreased significantly(P<0.01);the protein expression of SM22α was increased significantly(P<0.05 or P<0.01),and the high-dose Sanqi group and calcitriol group had more significant effects.Conclusion Sanqi can improve renal fibrosis and vascular calcification in CRF model rats,and its mechanism may be related to the regulation of biological functions of Sortilin and TLRs.
