Abstract:
Objective To study the relationship between serum urine regulator protein and cystatin C levels and pathological characteristics and prognosis in patients with hypertensive nephropathy.Methods A total of 100 patients admitted in the hospital from August 2021 to October 2022 were selected as the study group,and 40 healthy persons who underwent the physical examination in the hospital were selected as the control group,complete data of all patients were collected and analyzed,the levels of serum urinary regulatory protein and cystatin C in each group were tested,and the relationship between serum urinary regulatory protein and cysta-tin C levels,pathological characteristics,and prognosis was analyzed.Results The urine regulatory protein and glomerular filtration rate in the study group were lower than those in the control group,but cystatin C,u-rea nitrogen,and blood creatinine were all higher than those in the control group,and the differences were sta-tistically significant(P＜0.05).Urinary regulatory protein was negatively correlated with urea nitrogen and blood creatinine,but positively correlated with glomerular filtration rate(P＜0.05).Cystatin C was positively correlated with urea nitrogen and blood creatinine,but negatively correlated with glomerular filtration rate(P＜0.05).Urinary regulatory protein level was related to crescent formation,renal tubular atrophy/intersti-tial fibrosis(P＜0.05),while level the expression of cystatin C was related to glomerular segmental sclerosis,glomerular glomerular sclerosis,and glomerular ischemic shrinkage(P＜0.05).The survival rate of the high urinary regulatory protein level group(≥126.49 ng/mL)was higher than that of the low urinary regulatory protein level group(＜126.49 ng/mL),while the survival rate of the high cystatin C level group(≥2.43 mg/L)was lower than that of the low cystatin C level group(＜2.43 mg/L)(P＜0.05).Urinary regulatory protein,cystatin C,renal tubular atrophy/interstitial fibrosis were factors that affected the occurrence of end-stage renal disease in hypertensive nephropathy(P＜0.05).Conclusion Hypertensive kidney disease patients u-sually have higher levels of cystatin C and lower levels of urinary regulatory protein,among which cystatin C is closely related to pathological features of glomerular segmental sclerosis,glomerular glomerular sclerosis,and glomerular is-chemic shrinkage,and urinary regulatory protein is closely related to crescent formation,renal tubular atrophy/intersti-tial fibrosis.In addition,urinary regulatory protein and cystatin C have a significant impact on the development of hy-pertensive nephropathy into end-stage renal disease,and could become important indicators for evaluating patient prognosis.
