Fructus crataegi (hawthorn) is the common name of all plant species in the genus Crataegus of the Rosaceae family. In the present study, three monomers of (+)-catechin (C), (-)-epicatechin gallate (ECg) and (-)-epigallocatechin (EGC) were isolated from the hawthorn under the guide of antibacterial sensitization activity. The bioactivity of the composite(More)
Bacterial DNA (bDNA) and lipopolysaccharide (LPS) are potent activators of immune cells such as monocytes and macrophages, which contribute to systemic inflammatory response syndrome (SIRS) and sepsis. Unfortunately, many experimental inflammatory antagonist-based therapies have failed in sepsis trials, and currently there is only one adjuvant therapy in(More)
Styrene is a volatile organic compound that is widely used as an intermediate in many industrial settings. There are known adverse health effects at environmentally significant concentrations, but little is known about the molecular effect of exposure to styrene at sub-acute toxic concentrations. We exposed human lung epithelial cells, at a wide range of(More)
INTRODUCTION Abdominal distension is common in critical illness. There is a growing recognition that intra-abdominal hypertension (IAH) may complicate nonsurgical critical illness as well as after abdominal surgery. However, the pathophysiological basis of the injury to the intestinal mucosal barrier and its influence on the onset of abdominal compartment(More)
Gram-positive bacteria have become the most common organisms responsible for the development of sepsis. Staphylococcus aureus (S. aureus) is the major gram-positive pathogen in both community-acquired and nosocomial infections. The Mortality associated with nosocomial infections caused by S. aureus may vary but are generally high. In the present study, we(More)
Sepsis induced by methicillin-resistant Staphylococcus aureus (MRSA) has worse outcome because of multiresistance to a large group of antibiotics, which may lead to death from septic shock. In the present study, we firstly found that artesunate in combination with oxacillin was capable of protecting mice challenged with live MRSA WHO-2 (WHO-2) and the(More)
In the present study artemisinin (ART) was found to have potent anti-inflammatory effects in animal models of sepsis induced by CpG-containing oligodeoxy-nucleotides (CpG ODN), lipopolysaccharide (LPS), heat-killed Escherichia coli 35218 or live E. coli. Furthermore, we found that ART protected mice from a lethal challenge by CpG ODN, LPS, or heat-killed E.(More)
OBJECTIVES Occasionally, we found that artesunate enhanced the antibacterial effects of antibiotics in vitro. Therefore, the enhancement of various β-lactam antibiotics by artesunate against Escherichia coli and the possible mechanism were investigated in the present study. METHODS Antibacterial effects were observed using the serial 2-fold dilution(More)
Ulinastatin is a potent multivalent serine protease inhibitor, which was recently found with therapeutic potentials in treating sepsis, and the most life-threatening complication of critically ill population. However, the pharmacological features and possible mechanisms need to be further elucidated in reliable and clinical relevant sepsis models. As known,(More)
Colorectal cancer (CRC) is the third most common malignancy and the third leading cause of cancer related deaths in the United States. Almost 90% of the patients diagnosed with CRC die due to metastases. MicroRNAs (miRNAs) are evolutionarily conserved molecules that modulate the expression of their target genes post-transcriptionally, and they may(More)
