Roles of RAGE/ROCK1 Pathway in HMGB1-Induced Early Changes in Barrier Permeability of Human Pulmonary Microvascular Endothelial Cell.

Background: High mobility group box 1 (HMGB1) causes microvascular endothelial cell barrier dysfunction during acute lung injury (ALI) in sepsis, but the mechanisms have not been well understood. We studied the roles of RAGE and Rho kinase 1 (ROCK1) in HMGB1-induced human pulmonary endothelial barrier disruption.

Methods: In the present study, the recombinant human high mobility group box 1 (rhHMGB1) was used to stimulate human pulmonary microvascular endothelial cells (HPMECs).

Suppression of rice miR168 improves yield, flowering time and immunity.

MicroRNA168 (miR168) is a key miRNA that targets Argonaute1 (AGO1), a major component of the RNA-induced silencing complex. Previously, we reported that miR168 expression was responsive to infection by Magnaporthe oryzae, the causal agent of rice blast disease. However, how miR168 regulates immunity to rice blast and whether it affects rice development remains unclear.

Facile synthesis of magnetic molybdenum disulfide@graphene nanocomposite with amphiphilic properties and its application in solid-phase extraction for a wide polarity of insecticides in wolfberry samples.

A novel magnetic molybdenum disulfide@graphene (FeO/MoS@G) nanocomposite with amphiphilic properties was prepared via a co-mixing solvothermal method. To demonstrate the feasibility of FeO/MoS@G as a sorbent during sample preparation, it was employed for the magnetic solid phase extraction (MSPE) of ten pyrethroids, three triazoles and two acaricide pyridaben and picoxystrobin in an emulsified aqueous solution. Dichloromethane was used as the extractant to form an emulsified aqueous solution.

Prognostic value of red blood cell distribution width for severe acute pancreatitis.

Background: Severe acute pancreatitis (SAP) is a common condition in the intensive care unit (ICU) and has a high mortality. Early evaluation of the severity and prognosis is very important for SAP therapy. Recently, red blood cell distribution (RDW) was associated with mortality of sepsis patients and could be used as a predictor of prognosis.

Role of metabolic changes of mucosal layer in the intestinal barrier dysfunction following trauma/hemorrhagic shock.

Background: The mucosal layer plays an important role in regulating the intestinal barrier function. However, the underlying mechanisms of intestinal barrier dysfunction caused by trauma-hemorrhagic shock (THS) are still unknown.

Methods: In this study, we examined the barrier damages, inflammatory responses as well as the metabolic changes of the mucosal layer of the colon in a THS rat model.

Clinical Value of Ultrasonography in Diagnosis of Pulmonary Embolism in Critically Ill Patients.

Pulmonary embolism (PE) is a clinical emergency that will increase the mortality if complicated with unstable hemodynamics. Because of its nonspecific clinical symptoms, it's a great challenge to make a PE diagnosis. The golden standard to diagnose PE is computed tomography of pulmonary artery (CTPA), but a diagnosis of PE also composed of evaluation of PE risk factors, possibilities, and risk stratification.

Does training improve diagnostic accuracy and inter-rater agreement in applying the Berlin radiographic definition of acute respiratory distress syndrome? A multicenter prospective study.

Background: Poor inter-rater reliability in chest radiograph interpretation has been reported in the context of acute respiratory distress syndrome (ARDS), although not for the Berlin definition of ARDS. We sought to examine the effect of training material on the accuracy and consistency of intensivists' chest radiograph interpretations for ARDS diagnosis.

Methods: We conducted a rater agreement study in which 286 intensivists (residents 41.

Value of Kidney Disease Improving Global Outcomes Urine Output Criteria in Critically Ill Patients: A Secondary Analysis of a Multicenter Prospective Cohort Study.

Background: Urine output (UO) is an essential criterion of the Kidney Disease Improving Global Outcomes (KDIGO) definition and classification system for acute kidney injury (AKI), of which the diagnostic value has not been extensively studied. We aimed to determine whether AKI based on KDIGO UO criteria (KDIGOUO) could improve the diagnostic and prognostic accuracy, compared with KDIGO serum creatinine criteria (KDIGOSCr).

Methods: We conducted a secondary analysis of the database of a previous study conducted by China Critical Care Clinical Trial Group (CCCCTG), which was a 2-month prospective cohort study (July 1, 2009 to August 31, 2009) involving 3063 patients in 22 tertiary Intensive Care Units in Mainland of China.

The SNP rs1883832 in CD40 gene and risk of atherosclerosis in Chinese population: a meta-analysis.

Background: The complications of atherosclerosis such as coronary and cerebrovascular disease, are the most prevalent causes of mortality and morbidity worldwide. A single nucleotide polymorphism (SNP) rs1883832 (-1C/T) in CD40 gene has been recently suggested to contribute to the susceptibility to atherosclerosis in Chinese population; however, previous genetic association studies yielded inconsistent results.

Methods: A meta-analysis of eligible studies reporting the association between rs1883832 and atherosclerosis in Chinese population was carried out.

IL-4 -590C/T polymorphism and susceptibility to liver disease: a meta-analysis and meta-regression.

Interleukin-4 (IL-4) is a pleiotropic cytokine that plays an important role in the immune system. Emerging evidences have shown that the common polymorphism (-590C/T; rs2243250 C>T) in the IL-4 gene may play an important role in the development of various liver diseases, but individually published studies revealed inconclusive results. This meta-analysis aims to derive a more precise estimation of the association between the IL-4 -590C/T polymorphism and susceptibility to liver disease.

Downregulation of HMGB1 protects against the development of acute lung injury after severe acute pancreatitis.

Objective: To examine the effect of downregulation of high mobility group box 1 (HMGB1) on severe acute pancreatitis (SAP) associated with acute lung injury (ALI), and its subsequent effect on disease severity.

shRNAs targeting high-mobility group box-1 inhibit E-selectin expression via homeobox A9 in human umbilical vein endothelial cells.

The nucleus of the endothelial cell contains large amounts of high-mobility group box protein 1 (HMGB1), a cytokine mediator of inflammation, and the endothelium may be a crucial source of HMGB1 during the inflammatory response. Therefore, the downregulation of HMGB1 expression by RNA interference (RNAi) may decrease inflammatory activity. The aim of this study was to investigate the possible mechanism of action and the effect of HMGB1 on homeobox A9 (HOXA9) and E-selectin expression.
