摘要

Objective: To investigate the association between serum HIF-1α,β-catenin levels and the vascular calcification in the rat model of chronic kidney disease(CKD) vascular calcification. Methods: 30 SD male rats were randomly divided into normal control group (CON group, n = 10) and CKD vascular calcification group (CKD group, n = 20). Rats in calcification group were fed with adenine combined with high phosphorus diet. At the end of the 6th week, the blood and urine of the two groups were collected to detect renal function, calcium,phosphorus and 24-hour urinary protein, the renal tissue was stained with HE, the aorta of rats was stained with Von Kossa and calcium content was determined, and the levels of HIF-1 α and β-catenin in serum were detected by ElISA method. Results: compared with CON group, 24-hour urinary protein, blood BUN, Scr, P, Ca × P, aortic calcium content, serum HIF-1 α and β-catenin levels were significantly increased and serum calcium decreased in CKD group (P < 0.05); Glomerular atrophy, renal tubule dilatation and interstitial fibrosis were seen in CKD group, Von Kossa staining of calcified nodules in aorta showed more black substance deposition. The levels of serum HIF-1 α, β-catenin and serum P, Ca × P were positively correlated with the content of calcium in rat aorta. Conclusion: the levels of serum HIF-1 α and β-catenin are significantly increased in patients with vascular calcification in CKD, and they are significantly related to the degree of aortic calcification.
