BACKGROUND People who experience traumatic events have an increased risk of post-traumatic stress disorder (PTSD). However, PTSD-related pathological changes in the hippocampus and prefrontal cortex remain poorly understood. MATERIAL AND METHODS We investigated the effect of a PTSD-like animal model induced by severe stress. The experimental rats received(More)
BACKGROUND The treatment of acute respiratory distress syndrome (ARDS), most commonly seen during the organ dysfunction remains unsatisfied. Presently, the stem/progenitor cell-based endogenous repair has been aroused attention enormously. This report investigated the effects of retinoic acid (RA) plus simvastatin (SS) with respect to dynamics of lung(More)
Endogenous glucocorticoids (GCs) have both stimulatory and suppressive effects on immune cells depending on the concentration. However, the mechanisms underlying the stimulatory effects of GCs remain elusive. Rat peritoneal macrophages were treated with different concentrations of corticosterone (0, 30 nM, 150 nM, and 3  μ M). To inhibit the glucocorticoid(More)
INTRODUCTION The nucleotide-binding oligomerization domain-like receptor (NLR) family has been recognized as comprising intracellular pattern recognition receptors in which NLRP3 (NLR family, pyrin domain containing 3) plays an important role in the initiation of host immune inflammatory responses. The genetic variants have been recognized to be critical(More)
BACKGROUND Well-equipped comprehensive hospitals may provide better emergency and patient services for the recovery of injured patients from the earthquake zone. This study aimed to provide an overview of injuries among the patients admitted to the six teaching hospitals in Chongqing, China, after the 2008 Wenchuan earthquake. MATERIALS AND METHODS The(More)
Previous studies have demonstrated that acute lung injury (ALI) is associated with significant mortality and so far no effective pharmacotherapy is shown to reverse the natural progression. This study aims to investigate whether the transplantation of bone marrow derived mesenchymal stem cells (MSCs) might restore damaged pulmonary function and tissue(More)
In recent years, more and more research has shown that the lung is an organ of regenerative potential, with several types of stem/progenitor cells undergoing proliferation and differentiation after lung injury and participating the injury repair process. Mouse lung multipotent stem cells (MLSCs) have extensive self-renewal ability in culture and could(More)
Migration of epidermal stem cells (EpSCs) into wounds may play an important role in wound healing. Endogenous electric fields (EFs) arise naturally at wounds. Consistent with previous reports, we measured outward electric currents at rat skin wounds using vibrating probes. Topical use of prostaglandin E2 significantly promoted wound healing. However, it is(More)
BACKGROUND The regulation of neuroendocrine hormones on the innate immune responses remains controversial. This report investigated the effects of exogenous norepinephrine with respect to macrophage function as well as to elucidate the underlying mechanism. MATERIALS AND METHODS The adherence, chemotaxis, phagocytosis, and cytokine production of(More)
OBJECTIVE To investigate the polymorphisms of myeloid differentiation-2 (MD-2) gene promoters, and to explore whether such polymorphisms are associated with the susceptibility to multiple organ dysfunction syndrome (MODS) and sepsis in Chinese Han population. METHODS Using polymerase chain reaction-restriction fragment length polymorphism method, the(More)
