GSK3 modulation in acute lung injury, myocarditis and polycystic kidney disease-related aneurysm.

ABSTRACT: GSK3 are involved in different physical and pathological conditions and inflammatory regulated by macrophages contribute to significant mechanism. Infection stimuli may modulate GSK3 activity and influence host cell adaption, immune cells infiltration or cytokine expressions. To further address the role of GSK3 modulation in macrophages, the signal transduction of three major organs challenged by endotoxin, virus and genetic inherited factors are briefly introduced (lung injury, myocarditis and autosomal dominant polycystic kidney disease). As a result of pro-inflammatory and anti-inflammatory functions of GSK3 in different microenvironments and stages of macrophages (M1/M2), the rational resolution should be considered by adequately GSK3.

Project description:It has been suggested that fluid accumulation may delay recognition of acute kidney injury. We sought to determine the impact of fluid balance on the incidence of nondialysis requiring acute kidney injury in patients with acute lung injury and to describe associated outcomes, including mortality.Analysis of the Fluid and Catheter Treatment Trial, a factorial randomized clinical trial of conservative vs. liberal fluid management and of management guided by a central venous vs. pulmonary artery catheter.Acute Respiratory Distress Syndrome Network hospitals.One thousand patients.None.The incidence of acute kidney injury, defined as an absolute rise in creatinine of ?0.3 mg/dL or a relative change of >50% over 48 hrs, was examined before and after adjustment of serum creatinine for fluid balance. The incidence of acute kidney injury before adjustment for fluid balance was greater in those managed with the conservative fluid protocol (57% vs. 51%, p = .04). After adjustment for fluid balance, the incidence of acute kidney injury was greater in those managed with the liberal fluid protocol (66% vs. 58%, p = .007). Patients who met acute kidney injury criteria after adjustment of creatinine for fluid balance (but not before) had a mortality rate that was significantly greater than those who did not meet acute kidney injury criteria both before and after adjustment for fluid balance (31% vs. 12%, p < .001) and those who had acute kidney injury before but not after adjustment for fluid balance (31% vs. 11%, p = .005). The mortality of those patients meeting acute kidney injury criteria after but not before adjustment for fluid balance was similar to patients with acute kidney injury both before and after adjustment for fluid balance (31% vs. 38%, p = .18).Fluid management influences serum creatinine and therefore the diagnosis of acute kidney injury using creatinine-based definitions. Patients with "unrecognized" acute kidney injury that is identified after adjusting for positive fluid balance have higher mortality rates, and patients who have acute kidney injury before but not after adjusting for fluid balance have lower mortality rates. Future studies of acute kidney injury should consider potential differences in serum creatinine caused by changes in fluid balance and the impact of these differences on diagnosis and prognosis.

Project description:BackgroundAcute kidney injury (AKI) is a common complication of exertional heat stroke (EHS) with a complex pathogenesis. We established a stable mouse model of EHS-related AKI (EHS-AKI).MethodsC57BL/6 male mice were divided into 6 groups: Saline Control group, Glycerol Control group, Saline + Sham heat exercise (SHE) group, Saline + Heat exercise (HE) group, Glycerol + SHE group, and Glycerol + HE group. Samples from the Saline Control group and the Glycerol Control group were taken 6 h after the intramuscular injection of saline (4 mL/kg) or glycerol (4 mL/kg) to provide a baseline for comparisons with the other 4 groups. The other 4 groups of mice started exercise 6 h after the intramuscular injection of saline or glycerol, and were sacrificed to collect samples after exercise. Finally, serum and the pathology of kidney and muscle tissues were quantified.ResultsThere were no differences in the creatinine (Cr), blood urea nitrogen (BUN), creatine kinase (CK), and myoglobin (MYO) levels, but the interleukin 6 (IL-6) level was more increased (P<0.05) in the Glycerol Control group than the Saline Control group at the baseline. The IL-6 levels of the Glycerol + HE group were also higher than those of the Saline + HE groups at 6 and 12 h (P<0.05). The Cr levels at 12 h and 1 day, the BUN levels at 6 h, 12 h, 1 day, and 2 days in the Glycerol+ HE group were higher than the baseline levels (P<0.05). And the renal pathological scores at 6 h, 12 h, 1 day, 2 days, or 3 days were 0.79, 1.29, 1.58, 0.85, and 0.77. However, there was only slight renal pathological injury in the Saline + HE group at 12 h, and 1 day, and the scores were 0.13, and 0.41. The CK level in each group all peaked at 6 h after exercise and higher than the baseline (P<0.05). However, there was no difference in the MYO levels of each group compared to the baseline.ConclusionsWe established a stable mouse model of EHS-AKI by conducting a heat exercise after the intramuscular injection of glycerol. Our findings lay the foundation for follow-up clinical and basic research.
