Hyperin, a flavonoid compound found in Ericaceae, Guttiferae, and Celastraceae, has been reported to have anti-inflammatory effects. In the present study, we investigated the effects of hyperin on cisplatin-induced acute kidney injury (AKI) in mice. The renal tissue damage induced by cisplatin was detected by H&E staining. Blood urea nitrogen (BUN), creatinine, reactive oxygen species (ROS), and malondialdehyde (MDA) were also detected. Further, the effects of hyperin on cisplatin-induced TNF-α, IL-1β and IL-6 were detected by ELISA...

OBJECTIVE: Renal conservation (retention) of fluid might affect the outcome of hospital care and can be indicated by increased urinary concentrations of metabolic waste products. We obtained a reference material for further studies by exploring the prevalence of fluid retention in a healthy population. METHODS: Spot urine sampling was performed in 300 healthy hospital workers. A previously validated algorithm summarized the urine-specific gravity, osmolality, creatinine, and color to a fluid retention index (FRI), where 4...

OBJECTIVE: To determine whether a low perioperative minimum urine output target is safe and fluid sparing when compared with the standard target. BACKGROUND: A minimum hourly urine output of 0.5 mL/kg is a key target guiding perioperative fluid therapy. Few data support this standard practice, which may contribute to perioperative fluid overloading. METHODS: We randomized patients without significant risk factors for acute kidney injury undergoing elective colectomy to a minimum urine output target of 0...

Aristolochic acid nephropathy (AAN) is a progressive kidney disease caused by a Chinese herb containing aristolochic acid. Excessive death of renal tubular epithelial cells (RTECs) characterized the acute phase of AAN. Therapies for acute AAN were limited, such as steroids and angiotensin-receptor blockers (ARBs)/angiotensin-converting enzyme inhibitors (ACEIs). It was interesting that, in acute AAN, female patients showed relative slower progression to renal failure than males. In a previous study, female hormone 17β-estradiol (E2) was found to attenuate renal ischemia-reperfusion injury...

Background Though iodine deficiency in pregnancy is a matter of public-health concern, a functional measure of iodine status is lacking. The thyroid-specific protein, thyroglobulin (Tg), which reflects thyroid size, has shown promise as a functional measure in studies of children and adults, but data in pregnancy are sparse. In a cohort of mildly-to-moderately iodine-deficient pregnant women, we aimed to explore whether serum Tg is a sensitive functional biomarker of iodine status and to examine longitudinal change in Tg with gestational age...

OBJECTIVES: Hepatorenal syndrome (HRS) is a functional renal failure occurring in end stage liver disease, which is associated with poor prognosis. Terlipressin has been shown to be effective in treatment of HRS. More recently, it was suggested that noradrenaline, an alpha-adrenergic drug may be also effective in HRS. We aimed to compare the efficacy of noradrenaline versus terlipressin in treatment of HRS type 1. METHODS: Consecutive patients with cirrhosis and HRS type 1 were enrolled and randomised into 2 groups- Group A received intravenous noradrenaline infusion (0...

Previously, we documented that activation of protein kinase C-ε (PKC-ε) mediates mitochondrial dysfunction in cultured renal proximal tubule cells (RPTC). This study tested whether deletion of the PKC-ε decreases dysfunction of renal cortical mitochondria and improves kidney function after renal ischemia. PKC-ε levels in mitochondria of ischemic kidneys increased 24h after ischemia. Complex I- and complex II-coupled state 3 respirations were reduced 44% and 27%, respectively, in wild-type (WT) but unchanged and increased in PKC-ε-deficient (KO) mice after ischemia...
