Qingwen Baidu Decoction (QBD) is an extraordinarily "cold" formula. It was traditionally used to cure epidemic hemorrhagic fever, intestinal typhoid fever, influenza, sepsis and so on. The purpose of this study was to discover relationships between the change of the constituents in different extracts of QBD and the pharmacological effect in a rat model of acute lung injury (ALI) induced by lipopolysaccharide (LPS). The study aimed to discover the changes in constituents of different QBD extracts and the pharmacological effects on acute lung injury (ALI) induced by LPS...

Acute respiratory distress syndrome is characterized by diffuse inflammatory lung injury and is classified as mild, moderate, and severe. Clinically, hypoxemia, bilateral opacities in lung images, and decreased pulmonary compliance are observed. Sepsis is one of the most prevalent causes of this condition (30 - 50%). Among the direct causes of acute respiratory distress syndrome, chlorine inhalation is an uncommon cause, generating mucosal and airway irritation in most cases. We present a case of severe acute respiratory distress syndrome after accidental inhalation of chlorine in a swimming pool, with noninvasive ventilation used as a treatment with good response in this case...

REVIEW
Valbona Mirakaj, Peter Rosenberger
Neuronal guidance proteins (NGPs) were originally identified for their role during the embryonic development of the nervous system. Recent years have seen the discovery of NGP functions during immune responses. In this context, NGPs were demonstrated to control leukocyte migration and the release of cytokines during conditions of acute inflammation, such as lung injury or sepsis. However, NGPs also display potent actions in the resolution of inflammation, chronic inflammatory conditions, the development of atherosclerosis, and during ischemia followed by reperfusion...

BACKGROUND: Sepsis is the number one cause of lung injury in adults. Ex vivo lung perfusion (EVLP) is gaining clinical acceptance for donor lung evaluation and rehabilitation and may expand the use of marginal organs for transplantation. We hypothesized that 4 hours of normothermic EVLP would improve compliance and oxygenation in a porcine model of sepsis-induced lung injury. METHODS: We used intravenous lipopolysaccharide (LPS) to induce a systemic inflammatory response in a porcine model of lung injury...

Our previous study indicated that overexpression of nicotinamide phosphoribosyltransferase (NAMPT) aggravated acute lung injury, while knockdown of NAMPT expression attenuated ventilator-induced lung injury. Recently, we found that meta-carborane-butyl-3-(3-pyridinyl)-2E-propenamide (MC-PPEA, MC4), in which the benzoylpiperidine moiety of FK866 has been replaced by a carborane, displayed a 100-fold increase in NAMPT inhibition over FK866. Here, we determined the effects of MC4 and FK866 on cecal ligation and puncture (CLP) surgery-induced sepsis in C57BL/6J mice...

Inflammation is an important mechanism for the host to resist external infection and injury. Under normal conditions, adaptive inflammatory response not only is conducive to the repair of damaged cells and tissues, but plays an important role to promote the internal environment to restored homeostasis. However, when the immune function is damaged, the unresolved and uncontrolled inflammation will cause non-specific tissue damage, which is linked to a variety of inflammatory diseases. In the acute inflammation, resolvins, a group of endogenous small molecular lipid mediators which are biosynthesized by polyunsaturated fatty acids, possess anti-inflammatory and pro-resolving actions, which are benefit for the repair of damaged tissue...

In critical illness, such as sepsis or the acute respiratory distress syndrome, acute kidney injury (AKI) is common and associated with increased morbidity and mortality. Mechanical ventilation in critical illnesses is also a risk factor for AKI, but it is potentially modifiable. Injurious ventilation strategies may lead to the systemic release of inflammatory mediators from the lung due to ventilator induced lung injury (VILI). The systemic consequences of VILI are difficult to differentiate clinically from other systemic inflammatory syndromes, such as sepsis...

Objective Risk factors for placental abruption have changed, but there has not been an updated systematic review investigating outcomes. Methods We searched PubMed, EMBASE, Web of Science, SCOPUS, and CINAHL for publications from January 1, 2005 through December 31, 2016. We reviewed English-language publications reporting estimated incidence and/or risk factors for maternal, labor, delivery, and perinatal outcomes associated with abruption. We excluded case studies, conference abstracts, and studies that lacked a referent/comparison group or did not clearly characterize placental abruption...

OBJECTIVE: Exosomes are small, cell-released vesicles (40-100 nm in size) with the potential to transfer proteins, lipids, small RNAs, messenger RNAs, or DNA between cells via interstitial fluids. Due to their role in tissue homeostasis, exosomes have emerged as a new type of therapeutic and diagnostic (theranostic) tool in the noninvasive assessment of organ response to injury or treatment and in the development of reliable organ-protective intensive therapy. Our review provides current insights into the role of exosomes in the personalized management of injury and repair responses in critical illness...

We report a case of virus-induced acute respiratory distress syndrome (ARDS) treated with parenteral vitamin C in a patient testing positive for enterovirus/rhinovirus on viral screening. This report outlines the first use of high dose intravenous vitamin C as an interventional therapy for ARDS, resulting from enterovirus/rhinovirus respiratory infection. From very significant preclinical research performed at Virginia Commonwealth University with vitamin C and with the very positive results of a previously performed phase I safety trial infusing high dose vitamin C intravenously into patients with severe sepsis, we reasoned that infusing identical dosing to a patient with ARDS from viral infection would be therapeutic...

This paper describes the evolution of our understanding of the biological role played by synthetic and natural antimicrobial cationic peptides and by the highly basic nuclear histones as modulators of infection, postinfectious sequelae, trauma, and coagulation phenomena. The authors discuss the effects of the synthetic polymers of basic poly α amino acids, poly l-lysine, and poly l-arginine on blood coagulation, fibrinolysis, bacterial killing, and blood vessels; the properties of natural and synthetic antimicrobial cationic peptides as potential replacements or adjuncts to antibiotics; polycations as opsonizing agents promoting endocytosis/phagocytosis; polycations and muramidases as activators of autolytic wall enzymes in bacteria, causing bacteriolysis and tissue damage; and polycations and nuclear histones as potential virulence factors and as markers of sepsis, septic shock, disseminated intravasclar coagulopathy, acute lung injury, pancreatitis, trauma, and other additional clinical disorders...

Statins may offer protective effects in sepsis through anti-inflammatory, mitochondrial protection and other actions. We thus evaluated the effects of simvastatin on survival, organ and mitochondrial function, tissue and plasma ubiquinone levels and liver transcriptomics in a 3-day rat model of sepsis. Comparisons of rat plasma simvastatin and ubiquinone levels were made against levels sampled in blood from patients with acute lung injury (ALI) enrolled into a trial of statin therapy. Animals received simvastatin by gavage either pre- or post-induction of faecal peritonitis...

Zhuo Zhang, Jie Zhou, Changli Liao, Xiaobing Li, Minghua Liu, Daqiang Song, Xian Jiang
Lidocaine (Lido) is reported to suppress inflammatory responses and exhibit a therapeutic effect in models of cecal ligation and puncture (CLP)-induced acute lung injury (ALI). The receptor for advanced glycation end product (RAGE) exerts pro-inflammatory effects by enhancing pro-inflammatory cytokine production. However, the precise mechanism by which Lido confers protection against ALI is not clear. ALI was induced in RAGE WT and RAGE knockout (KO) rats using cecal ligation and puncture (CLP) operations for 24 h...

BACKGROUND: Sepsis induced acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are lifethreatening disorders. Acute Physiology and Chronic Health Evaluation (APACHE) scores and several plasma biological markers have been identified to predict the death or treatment outcome of sepsis induced ALI. Immune related microRNAs also have the potential as biomarkers to monitor this kind of disease. METHODS: A total of 44 patients with severe sepsis, 102 patients with sepsis, and 19 healthy volunteers were enrolled in this study...
