Résumé

Objective To study the therapeutic effect of bitter gourd saponins on salt-sensitive kidney injury induced by high salt diet and its possible mechanism.Methods 50 Sprague Dawley (SD) rats were randomly divided into normal group,model group and low-dose,middle-dose and high-dose treatment group after 10 days of adaptive feeding.Each group had 10 rats.Except the normal group,the other four groups were given high salt diet (4.0% high salt diet) to induce salt-sensitive kidney damage in rats.The normal group and the model group were given 1.0 m/(kg · d) normal saline,and the three dosage groups of total saponins of balsam pear were given 10 mg/(kg · d),20 mg/(kg · d) and 40 mg/(kg · d) respectively.After 8 weeks of treatment,rats were sacrificed and collect the 24-hour proteinuria,creatinine.Serum creatinine,serum aldosterone,serum sodium and serum potassium were measured,and renal histopathology and the expression of podocin and nephrin were detected.Results Pathological examination of model group showed obvious glomerular sclerosis and renal interstitial fibrosis,and glomerular sclerosis in the treatment group was obviously improved by bitter gourd saponins;The systolic pressure in the model group was 170 mmHg,significantly higher than that of the normal and treatment groups,the systolic blood pressure of the treatment groups were obvious decreased when treated by bitter gourd saponins (P < 0.05);Compared with normal group,serum creatinine and 24 h proteinuria / urine creatinine in model group were significantly increased (P < 0.05),while creatinine clearance rate and aldosterone were significantly decreased (P < 0.05),and the above indexes in bitter gourd saponins treatment group were significantly improved;Compared with the model group,the protein and mRNA expression of podocin and nephrin were significantly decreased (P < 0.05),while the two indexes can be revered by bitter gourd saponins in treatment group (P < 0.05).Conclusions The bitter gourd saponins can significantly improve the symptoms of salt-induced hypertensive nephropathy in rats,which may be related with the expression of podocin and nephrin in renal tissue,thereby inhibiting glomerulosclerosis and improving renal interstitial fibrosis.

Résumé

Objective To investigate the prevalence of chronic kidney disease (CKD) in hospitalized patients with essential hypertension (EH) and analyze the related risk factors.Methods A retrospectivc analysis of chronic kidney disease and its influencing factors was taken from March 2014 to March 2015 in the Second Affiliated Hospital of Nanjing Medical University.People were diagnosed EH patients (1 020 cases).Results (1) The detection rates of proteinuria,estimated glomerular filtration rate (eGFR) and CKD in patients with EH were 22.3%,13.3%,and 26.1%,respectively.The ratio of CKD in male and female was 26.8% vs 25.5% (P>0.05);(2) With the increase in systolic blood pressure levels (as the systolic blood pressure increased 20 mmHg),the constituent ratio of CKD increased with statistically significant difference (P < 0.05);(3) The risk factors of essential hypertension complicated with chronic kidney disease were high uric acid,the history of diabetes,SBP ≥ 140 mmHg and the age (OR =2.682,2.224,1.932,1.065).Conclusions The detection rate of CKD in patients with hypertension in was high,and the blood pressure,blood glucose,and serum uric acid should be controlled to prevent and delay the occurrence and development of CKD.

Résumé

Objective To evaluate the value of neutrophil gelatinase - associated lipocalin (NGAL) for diagnosis of acute kidney injury (AKI) after cardiopulmonary bypass established. Method 120 children undergoing cardiopulmonary bypass were enrolled in this prospectively study. Serial urine samples were analyzed by ELISA for NGAL expression. The primary outcome measure was AKI, which was defined as a 50% or greater increase in serum creatinine from baseline. Result 21 children ( 17.5% ) developed AKI. Urine concentrations of NGAL increased after cardiopulmonary bypass had been established for 2 hours. The concentration of NGAL in urine after cardiopulmonary bypass had been established for 2 hours was used to diagnose AKI. The area under the receiver-operating characteristic curve was 0. 96, the sensitivity was 92%, and the specificity was 91% for the cutoff value of 100ng/mg Cr. Conclusion Concentrations of NGAL in urine might be used as a sensitive and specific biomarker for early prediction of AKI after cardiopulmonary bypass had been established.

Résumé

Objective To investigate effects of oxidative stress, expression change of transforming growth factor-β1 and Nestin in re-nal injury of hyperthyroidism rats. Methods The model of hyperthyroidism rat was made by giving them levothyroxine (L-T4). The activity of SOD, CAT, GSH-Px and the level of MDA on the 25th day, the 45th day, and the 60th day were determined by chromatometry in renal cor-tex.. The expressions of TGF-β1 and Nestin on the 25th day, the 45th day, and the 60th day were determined by immunohistochemistry. Results Along with the course of hyperthyroidism, it showed activity of SOD, CAT, GSH-Px and the expression of Nestin reduced, while the level of MDA and the expression of TGF-β1 increased. Conclusion Oxidative stress can increas the expression of TGF-β1 and podocyte in-jury may played an important role in hyperthyroidism renal injury.
