ABSTRACT
Portal vein thrombosis (PVT) is one of the most common complications of liver cirrhosis. Due to coagulation disorder and the risk of bleeding in liver cirrhosis, there are many controversies over the treatment of liver cirrhosis with PVT in clinical practice. Common therapies for PVT include anticoagulant therapy, intervention, and thrombolysis. This article elaborates on the current status of the treatment of liver cirrhosis with PVT, in order to provide help for the development of standard and reasonable clinical treatment strategies.
ABSTRACT
@#Objective To investigate the effect of olfactory mucosal neural stem cells (OM-NSCs) on neuronal apoptosis in rats. Methods OM-NSCs were isolated from adult male Sprague-Dawley rats, and neurons were isolated from fetal Sprague-Dawley rats. The neurons were divided into blank group, control group and experiment group after culture in vitro, which were further cultured in nomal, cultured in nomal 24 hours after stimulation of interleukin-1β (IL-1β), and cultured with OM-NSCs 24 hours after stimulation of IL-1β, respectively, for 24 hours. The apoptosis of neurons was observed with double staining of TUNEL and microtubule-associated protein 2 antibodies. Results There were few apoptotic cells in the blank group, and very many in the control group; the apoptotic cells were fewer in the experiment group than in the control group (F=39.764, P<0.01).Conclusion OM-NSCs can significantly inhibit neuronal apoptosis, which may play a role in neuroprotection.
ABSTRACT
@#Spinal cord injury (SCI) often causes different degrees of sensory and motor dysfunction, resulting in permanent disability, with many complications and difficult to cure. Metabolomics, as a new developing technique, identifies specific biomarkers for diagnosis, treatment or prognosis judgement by analyzing the changes in the metabolites after individual stress, and can make the best treatment and rehabilitation program for the patients in the early stage of the disease. At present, some achievements have been made in the diagnosis, treatment and prognosis monitoring of spinal cord injury, and some potential biomarkers have been identified. However, the pathophysiology of spinal cord injury is not fully understood, and relevant biomarkers are also lacking in clinical trials.
ABSTRACT
@#Objective To investigate the effect of Ski on the secretion of inflammatory cytokines from activated astrocytes. Methods Astrocytes were obtained from cerebral cortex of a three-day old Sprague-Dawley rat and cultured in vitro. They were divided into blank group, control group and siRNA group. The Ski gene was silenced in siRNA group. The expression of Ski was tested with Western blotting and immunofluorescence 48 hours later. Then the astrocytes were stimulated with lipopolysaccharide for 24 hours. The secretion of tumor necrosis factor α (TNF-α) and interleukin-1β (IL-1β) in activated astrocytes was detected with ELISA. Results The expression of Ski protein reduced in the siRNA group (P<0.001), as well as the secretion of TNF-α and IL-1β (P<0.001). Conclusion Ski may play a role in inflammatory response of astrocyte.
