ABSTRACT
Objective To investigate the significance of acute kidney injury biomarkers with calcineurin inhibitors (CNI) related nephrotoxicity in the treatment of refractory nephritic syndrome.Methods Ninety-two patients were included with 59 males and 33 females with average age of (5.67 ± 3.65) years old,who were diagnosed with nephrotic syndrome at Shanghai Children's Hospital from March 2014 to December 2015.66 patients including 44 males and 22 females with mean age of (4.97 ± 3.52) were treated by steroid as the control group and 26 patients including 15 males and 11 females with mean age of (6.59 ± 3.95) were treated by steroid combined with CsA and FK506 as the observation group.The blood,urine samples were collected before drug treatment (0 d) and very early stage of treatment (3 d),early stage (1 month),middle and late stage (3 months and 6 months) as the different observation time points.The change level of neutrophil gelatinase associated lipocalin(NGAL),kidney injury molecular-1 (KIM-1),fibronectin(FN) and tumor necrosis factor-alpha(TNF-α) in serum and urine were detected at different time points to compare with biomarkers such as retinol-binding protein(RBP),N-acetyl-β-D-glucosamccharase(NAG) in urine.Results The serum NGAL(sNAGL) level was more obvious after 6 months of CNI treatment in the observation group than in the control group[(138.00 ±32.49) μg/L vs.(46.54± 11.41) μg/L,t =2.115,P ＜0.05];the level of urine TNF-oα(uTNF-α) was higher obviously after 6 months of CNI treatment in the observation group than in the control group with significant differences [(2.35 ± 0.78) pg/μmol vs.(0.75 ± 0.36) pg/μmol,t =1.840,P ＜ 0.05];the level of urine KIM-1 (uKIM-1) was lower in the observation group than the control group after 3 months treatment of the CNI [(0.15 ± 0.03) ng/μmol vs.(0.33 ± 0.07) ng/μmol,t =-2.077,P ＜ 0.05);the level of urine NGAL (uNGAL) was lower in the observation group than the control group after 3 months treatment of the CNI [(0.09 ±0.03) ng/μmol vs.(0.23 ± 0.04) ng/μmol,t =-2.959,P ＜ 0.05].But the serum TNF-α (sTNF-α),urine FN (uFN),urine RBP(uRBP) and urine NAG (uNAG)did not show any significant change before and after the C NI treatment.Conclusions Compared with other acute kidney injury biomarkers (uNGAL,KIM-1,FN,RBP,and NAG),sNAGL and uTNF-α may be more sensitive to the early evaluation of CNI related nephrotoxicity.The occurrence of CNI related kidney injury shall be watched out at the beginning of 6-month of CNI treatment.

ABSTRACT
Objective To explore the value of superb microvacular imaging ( SMI) technology in differentiating thyroid microcarcinomas from benign micronodules comparing with contrast‐enhanced ultrasound (CEUS) . Methods A total of 195 thyroid micronodules ( ≤1 .0 cm) from 172 patients were examined using CEUS and SMI ,and the findings were reviewed and evaluated in comparison to the pathological results . Results Of all the 195 thyroid nodules ,pathologic findings revealed that 140 (71 .8% ) were malignant and 55 (28 .2% ) were benign ,CEUS diagnosed that 127 (65 .1% ) were malignant and 68 (34 .9% ) were benign ,and SMI diagnosed that 129 (66 .2% ) were malignant and 66 (33 .8% ) were benign . There were no differences between the SMI and CEUS in terms of sensitivity ( 90 .0% vs 87 .9% ) , specificity ( 94 .5% vs 92 .7% ) ,accuracy ( 91 .3% vs 89 .2% ) ,positive predictive value ( 97 .7% vs 96 .9% ) and negative predictive value ( 92 .9% vs 87 .9% ) ( P > 0 .05 for all) . Conclusions SMI can effectively observe the perforating blood vessels of thyroid micronodules , which plays an important role in differentiating of benign and malignant thyroid micronodules .
ABSTRACT
Cyclosporine A (CsA)has been widely used in steroid-dependent and steroid-resistant nephrotic syndrome as a common drug.However,renal toxicity can often occur at the same time which limited the use of CsA.CsA can lead to acute and chronic renal damage,ischemic renal tissue inflammation,and fibrosis.Currently in clinical practice,urine micro proteins and serum creatinine have been used to monitor CsA associated nephrotoxicity.However,this method cannot detect CsA associated renal damage in early stage.At present,a hot topic about CsA focuses on looking for a better non-invasive and sensitive way to monitoring CsA associated nephrotoxicity.This article reviews the current progress of known acute kidney injury biomarkers in momtoring CsA associated nephrotoxicity.
