In the present study, we observed the expression of toll-like receptor 4 (TLR4) and its downstream signal pathway in peripheral blood monocytes (PBMs) from patients with acute cerebral infarct (ACI). The expression of TLR4 and MyD88 by PBMs was determined by flow cytometry and reverse transcriptase-polymerase chain reaction, and nuclear factor-kappaB(More)
High-mobility group protein box-1 (HMGB1) has recently been recognized as a novel candidate in a specific upstream pathway promoting inflammation after brain ischemia. However, its downstream pathway and underlying mechanism have yet to be elucidated. The HMGB1 level in the acute cerebral infarct (ACI) group was significantly increased compared with that of(More)
High-mobility group protein box-1 (HMGB1) is a proinflammatory involved in many inflammatory diseases. However, its roles in intracerebral hemorrhage (ICH) remain unknown. The purpose of this study was to examine the correlation between changes in serum levels of HMGB1 following acute ICH and the severity of stroke as well as the underlying mechanism.(More)
High-mobility group box-1 (HMGB1) was originally identified as a ubiquitously expressed, abundant, nonhistone DNA-binding protein. It has well-established functions in the maintenance of nuclear homeostasis. The HMGB1 can either be passively released into the extracellular milieu in response to necrotic signals or actively secreted in response to(More)
Detecting small target of ship at sea is very important to missile guidance. In this paper, infrared images are used to capture the information of small ship at sea, an edge detector combining with a median filter are used to seek for the sky-sea line and the objects in the images. According to the features of ship targets in sky-sea background, a criterion(More)
An algorithm to locate sea-sky line in infrared image with sea-sky background is suggested in this paper. In this algorithm, the modified Canny method is combined with a median filter, its two thresholds are designed to be adaptive based on the properties of these infrared images. A criterion is set up to distinguish the sky-sea line from other objects in(More)
OBJECTIVE To observe the changes of human leukocyte antigen DR (HLA-DR) expression in monocytes of trauma patients and its value of prediction on infection complications. METHODS Fifty-four trauma patients were divided into three groups according to severity of injury: severe trauma group injury severity score (ISS) >or=25, moderate trauma group(More)
BACKGROUND The placement of an enteral feeding tube is the foundation for providing enteral nutrition. But due to the anatomic complexity of the stomach and the duodenum, to a certain degree, there are some technical difficulties in the placement of postpyloric feeding tube, especially in critically ill patients. This study aimed to evaluate the efficacy(More)
OBJECTIVE To study the effect of decoy-oligodeoxynucleotides (decoy-ODNs) in dumbbell shape with the oligodeoxynucleotide sequence similar to nuclear factor kappa B (NF-kappaB) cis-elements on expression of inflammation mediators in pMPhi cells from rats. METHODS With carriers of cationic liposomes, decoy-ODNs were transfected into pMPhi cells of rats.(More)
AIM To clone NF-kappaB p50 Rel homology domain (RHD) gene and construct the "bait" vector in yeast two-hybrid system, and detect the yeast cell toxicity and autonomous reporter gene activity of target gene. METHODS Total RNA was extracted from human peripheral blood mononuclear cells and NF-kappaB p50 RHD gene was amplified by RT-PCR, and cloned into(More)
