Hypertonic saline maintains coagulofibrinolytic homeostasis following moderate‑to‑severe traumatic brain injury by regulating monocyte phenotype via expression of lncRNAs.

Traumatic brain injury (TBI) is the most common cause of death and permanent disability in people aged <45, and is associated with secondary brain injury and bleed progression, resulting in increased morbidity and mortality. TBI may also induce innate host defense responses characterized by activation of resident microglia and astrocytes, brain microvascular endothelial cells and peripheral blood monocytes. In the present study, 34 patients with moderate‑to‑severe traumatic brain injury were randomly divided into two groups, including a 7.

Comparison of two different models of sepsis induced by cecal ligation and puncture in rats.

Background: The present study was designed to explore the difference between two rat models of sepsis and to establish a more stable rat model.

Materials And Methods: Sprague-Dawley rats were randomly divided into three groups: sham operation group, simple cecal ligation and perforation group (SCLP), and cecal ligation perforation plus drainage group (CLP-DS). The general condition of the rats was observed, and the time of death and survival rate at 72 h were recorded.

Synergistic protection of Schizandrin B and Glycyrrhizic acid against bleomycin-induced pulmonary fibrosis by inhibiting TGF-β1/Smad2 pathways and overexpression of NOX4.

Pulmonary fibrosis, a progressive and lethal lung disease, is a major therapeutic challenge for which new therapeutic strategies are warranted. Schisandrin B (Sch B) and Glycyrrhizic acid (GA) are the principal active ingredients of Schisandra chinensis and Glycyrrhiza glabra respectively, which have been reported to protect against lung injures. The present study was aimed at exploring the combinatorial therapeutic effects on bleomycin-induced pulmonary fibrosis.

Synthesis and immunogenicity of PG-tb1 monovalent glycoconjugate.

A PG-tb1 hapten from the West Beijing strains of Mycobacterium tuberculosis cell wall has been efficiently synthesized and conjugated to CRM in a simple way as linker-equipped carbohydrate by applying squaric acid chemistry for an original neoglycoprotein, creating a potent T-dependent conjugate vaccine. The intermediate monoester can be easily purified and the degree of incorporation can be monitored by MALDI-TOF mass spectrometry. After administered systemically in mice without any adjuvant, the conjugate induced high antigen-specific IgG levels in serum.

Intratracheal Instillation of Perfluorohexane Modulates the Pulmonary Immune Microenvironment by Attenuating Early Inflammatory Factors in Patients With Smoke Inhalation Injury: A Randomized Controlled Clinical Trial.

Smoke inhalation injury (SII) is associated with significant morbidity and mortality in burn patients, and effective treatments are lacking. Perfluorocarbons (PFCs) have a protective effect against acute lung injury. We aimed to assess the therapeutic effects of perfluorohexane on burn patients with SII.

Quality of life in long-term oral cancer survivors: an 8-year prospective study in China.

Objectives: The purpose of the prospective study was to evaluate the long-term changes in quality of life (QOL) in patients with oral cancer and to examine the potential factors that predicted QOL at 8 years after treatment.

Study Design: Seventy-one patients were evaluated by the University of Washington quality of life scale. QOL in 30 long-term survivors was assessed at diagnosis and at the 3-month, 1-year, and 8-year follow-up.

2015 Nepal Earthquake: Analysis of Child Rescue and Treatment by a Field Hospital.

Objective: To retrospectively analyze the rescue and treatment of pediatric patients by the Chinese Red Cross medical team during the Nepal earthquake relief.

Methods: The medical team set up a field hospital; the pediatric clinic consisted of 1 pediatrician and several nurses. Children younger than 18 years old were placed in the pediatric clinic for injury examination and treatment.

Dynamic Tracking Human Mesenchymal Stem Cells Tropism following Smoke Inhalation Injury in NOD/SCID Mice.

Multiple preclinical evidences have supported the potential value of mesenchymal stem cells (MSCs) for treatment of acute lung injury (ALI). However, few studies focus on the dynamic tropism of MSCs in animals with acute lung injury. In this study, we track systemically transplanted human bone marrow-derived mesenchymal stem cells (hBMSCs) in NOD/SCID mice with smoke inhalation injury (SII) through bioluminescence imaging (BLI).

In Vivo Tracking of Systemically Administered Allogeneic Bone Marrow Mesenchymal Stem Cells in Normal Rats through Bioluminescence Imaging.

Recently, mesenchymal stem cells (MSCs) are increasingly used as a panacea for multiple types of disease short of effective treatment. Dozens of clinical trials published demonstrated strikingly positive therapeutic effects of MSCs. However, as a specific agent, little research has focused on the dynamic distribution of MSCs after in vivo administration.

Salvianolic acid B protects against paraquat-induced pulmonary injury by mediating Nrf2/Nox4 redox balance and TGF-β1/Smad3 signaling.

The present study was aimed at exploring the protective effects of Salvianolic acid B (SalB) against paraquat (PQ)-induced lung injury in mice. Lung fibrotic injuries were induced in mice by a single intragastrical administration of 300mg/kg PQ, then the mice were administrated with 200mg/kg, 400mg/kg SalB, 100mg/kg vitamin C (Vit C) and dexamethasone (DXM) for 14days. PQ-triggered structure distortion, collagen overproduction, excessive inflammatory infiltration, pro-inflammatory cytokine release, and oxidative stress damages in lung tissues and mortality of mice were attenuated by SalB in a dose-dependent manner.

Continuous plasma perfusion of dual cartridges in series: rationale and early clinical experience.

To improve the efficiency of plasma perfusion on eliminating plasma paraquat (PQ), we designed continuous plasma perfusion of dual cartridges in series (CPPDCS) on Diapact Braun CRRT machine. The goals of this study were to evaluate the effective of CPPDCS on paraquat removal in patients with acute paraquat intoxication. Our results show that the PQ clearance rate of dual cartridges was significantly higher than that of single cartridge at 1st, 2nd, 3, and 4th plasma perfusion.
