    Changes of renal artery resistance index and its correlation with early renal injury in patients with chronic kidney disease by Zhu Yong-jun, Yu Rong, Cao Yan-wei, Lin Zi-yan, Yang Jing, Gao Ke-li, Wang Ying, Cui Hong-wang

    Published 2021-01-01
    “…Objective To explore the changes of renal artery resistance index(RRI)in patients with chronic kidney disease(CKD)at different stages and examine its correlation with early renal function damage.Methods From January 2016 to September 2020,clinical data of 611 CKD patients were collected as case group.Estimated glomerular filtration rate(eGFR)was calculated by CKD-EPIscr equation.The case group was further divided into 5 groups according to CKD stage.Meanwhile 100 healthy volunteers in the same period were chosen as control group.RRI,serum β2-microglobulin(β2-MG),serum cystatin C(CysC),serum creatinine(Scr)and serum urea nitrogen(BUN)were measured.The differences between case and control groups were compared by one-way ANOVA;the abnormal detection rate of each group was calculated; the diagnostic efficiency of the above indicators in CKD patients was analyzed by receiver operating characteristic(ROC)curve.Results The mean values of RRI,β2-MG,CysC,Scr and BUN were higher in each case group than those in control group(P<0.05).In stages 1 and 2,the abnormal detection rate of β2-MG,CysC and RRI was higher than that of any single detection index, followed by the abnormal detection rate of RRI.Receiver operating characteristic(ROC)curve showed that area under the curve(AUC)and Youden index of RRI were the largest in single detection indexand AUC and Youden index of combined detection of β2-MG,CysC and RRI were the largest.Conclusion RRI,β2-MG and CysC may be utilized as sensitive detection parameters of early renal damage in CKD,especially RRI.Combined detection of β2-MG,CysC and RRI can improve abnormal detection rate and boost diagnostic efficiency.Thus it provides clinical references for early diagnosis and treatment of CKD.…”

    What is the pathophysiology of inflammation-induced cortical injury in the perinatal brain? by Sharmony B. Kelly, Alistair J. Gunn, Rodney W. Hunt, Robert Galinsky

    Published 2026-02-01
    “…However, our understanding of the pathophysiological substrate underpinning these changes in brain structure and function is limited. The objective of this review is to summarize the growing evidence from animal trials and human cohort studies that suggest exposure to infection/inflammation during the perinatal period promotes regional impairments in neuronal maturation and function, including loss of high-frequency electroencephalographic activity, and reduced growth and arborization of cortical dendrites and dendritic spines resulting in reduced cortical volume. …”

    Protective effect of autologous adipose-derived mesenchymal stem cells on renal ischemia reperfusion injury by HUANG Ke-jing, HUANG Ting, HU Wen-bing, XIANG Li-na

    Published 2017-01-01
    “…Objective To observe the protective effects of tail veil injection of autologous adipose-derived mesenchymal stem cells(ADMSCs) on the renal ischemia reperfusion(IR) injury of rats.Methods Adult male Sprague-Dawley(SD) rats(n = 24) were equally randomized into sham operation group(sham control),IR injury model group(IR plus saline only),and cell therapy group(IR plus intravenous administration of 1.OX 106 autologous ADMSCs),n = 8 each group.Fourteen days before IR,the adipose tissue around the greater omentum was cut for the preparation of ADMSCs.Twentyfour h before modeling,serum creatinine,urine volume and urinary albumin/creatinine ratio were evaluated as blank controls.The renal IR injury model was set up.In the sham group,the middle incision was cut and sutured.One h after IR,ADMSCs were transplanted through tail vein of rats in cell therapy group,and the same volume of normal saline was injected into the rats of sham operation group and model group.The renal functional indexes including serum creatinine,urine volume and urinary albumin/creatinine ratio were detected by biochemical method 24 h and 72 h after IR.The pathological changes were observed by HE staining,and the relative expression of HO-1 and NQO-1 was detected by Western blotting.Results The results of biochemical detection(serum creatinine and urinary albumin/creatinine ratio) showed that the kidney function of rats in cell therapy group was significantly better than in model group(P<0.05).The histopathological observation showed that the obvious morphological damage was observed in the renal tubule in model group,and amelioration was observed in cell therapy group.Western blotting showed notably higher expression of NAD(P) H quinone oxidoreductase KNQO1 and HOI proteins,two indicators of anti-oxidative capacity,in cell therapy group than in model group.Conclusions ADMSCs therapy minimized kidney damage after IR injury through suppressing oxidative stress.…”
