BACKGROUND Recent observations have suggested that overexpression of cyclooxygenase-2 (COX-2) promotes tumor lymphangiogenesis through an upregulation of vascular endothelial growth factor-C (VEGF-C) expression. It is unclear whether this mechanism also acts in gastric cancer. The aim of this study was to determine the relationship between COX-2 and VEGF-C(More)
BACKGROUND Acute kidney injury (AKI) is a common pathological process which occurs in hemorrhage, intoxication, etc. It has been shown that the lymphatic circulation plays an important regulatory role in the pathogenesis of hemorrhage shock, and that exogenous normal lymph (ENL) has a beneficial effect on multiple organ injuries. In the present study, we(More)
There is increasing evidence indicating that the distant organ injury is a major contributor of high mortality in patients subjected to acute renal failure (ARF). However, sources and mechanisms that ARF causes distant organ injury remain to be determined. The aim of this study is to explore the mechanism from polymorphonuclear neutrophil (PMN)(More)
AIM To investigate the effect of exogenous normal lymph on kidney injury in disseminated intravascular coagulation (DIC) rats and to probe its mechanism. METHODS The DIC model was established by intravenous injection of Dextran 500. After 6 min, normal lymph without cell components was infused in the lymph group. After 40 min, the renal and coagulation(More)
OBJECTIVE To observe the effects of exogenous normal lymph on myeloperoxidase (MPO) and adenosine triphosphatase (ATPase) activities of lung homogenate in rats with endotoxic shock caused by lipopolysaccharide (LPS), and to preliminarily discuss its mechanisms. METHODS Forty male Wistar rats were randomly divided into four groups: endotoxin group, lymph(More)
AIM To study the effect of blocking intestinal lymphatic circulation in two-hit rats and explore the significance of intestinal lymphatic circulation in two-hit. METHODS Wistar rats were divided equally into three groups: mesenteric lymph duct ligation group, non-ligation group and sham group. Mesenteric lymph was diverted by ligation of mesenteric lymph(More)
Vascular hyporeactivity is an important factor in irreversible shock, whereas calcium desensitization is one of the mechanisms of vascular hyporeactivity, and the intestinal lymphatic pathway plays an important role in multiple organ injury after severe hemorrhagic shock (HS). In this study, our aims were to determine the effects of mesenteric lymph on(More)
BACKGROUND The kidney is a common target in multiple organ dysfunction syndrome (MODS). The aim of this study is to determine the role of intestinal lymphatic pathway on renal injury in hemorrhagic shock rats. METHODS Wistar rats were divided into sham, shock, and ligation groups. The hemorrhagic shock model was induced in the shock and ligation groups.(More)
Immune function disorders are common during acute renal failure (ARF), but the mechanisms are unknown. As the spleen is the largest organ of the immune system, we aimed to observe if there are morphological changes in the spleen in rabbits with ARF. In addition, we tried to explore its mechanism from the perspective of oxygen free radicals, nitric oxide(More)
