4.Expression of procaspase-3 in the mouse hippocampus after transient forebrain ischemia
Chinese Journal of Tissue Engineering Research 2005;9(32):225-227
BACKGROUND:After cerebral ischemia/reperfusion injury,as a executioner caspase, procaspase-3 and caspase-3-like activity increased significantly. We observe both the dephosphorylated and phosphorylated procaspase-3, and try to find out their variations during the processes of cerebral ischemia/reperfusion injury.OBJECTIVE:Observe the expression of procaspase-3 in hippocampus following transient forebrain ischemia.DESIGN: A randomized and controlled experiment.DEPARTMENT:Department of Biochemistry and Molecular Biology,Capital University of Medical Sciences.SETTING:Department of Hyperbaric Oxygen of Beijing Chaoyang Hospital Affiliated to Capital University of Medical Sciences.METHODS:Transient forebrain ischemia was induced by bilateral common carotid occlusion (BCCAO) for 20 minutes. Hippocampus was obtained at reperfusion time points of 6 hours, 12 hours,24 hours and 48 hours respec-tively after 20 minutes of BCCAO. Sham-operated group did not occlude bi-lateral common carotid, and hippocampus was obtained at reperfusion time point of 24 hours. Western Blotting was used to detect the level of procaspase-3.MAIN OUTCOME MEASURES:The comparison of total procaspase-3,dephosphorylated procaspase-3 and phosphorylated procaspase-3 level in hippocampus between each group.3 level: Total procaspase-3 level increased in hippocampus at reperfusion time points of 12 hours and 24 hours post-BCCAO (9 133.1 ±2 216.3,dephosphorylated procaspase-3 level increased in hippocampus at reperfusion time point of 24 hours post-BCCAO (7812.0±1625.1, 3825.8±155.6, P was not significant (P > 0.05) as compared with the expression levels in sham-operated mice.CONCLUSION: Procaspase-3 is upregulated after ischemia/reperfusion.The increment of dephosphorylated form of procaspase-3 was higher than that of phosphorylated form of procaspase-3 upon cerebral ischemia/reperfusion injury, which indicates that cerebral ischemia/reperfusion injury possibly induced the dephosphorylation of procaspase-3 and promoted its transforming into activated form.
5.9-(4-Ethoxycarbonylphenoxy)-6,7-dimethoxy-1,2,3,4-tetrahydro acridine inhibits free radical induced rat cortical neuron cytotoxicity and cerebral ischemia injury
Acta Pharmaceutica Sinica 2003;38(5):337-341
Aim To study the effects of 9-(4-ethoxycarbonylphenoxy)-6,7-dimethoxy-1,2,3,4-tetrahydro acridine (EDT) on free radical induced injury in primary cultured rat cortical neuron and cerebral ischemia in mice. Methods In primary rat cortical neuron, free radical injury model was established by 10 μmol*L-1 H2O2. The content of malondiadehyde (MDA) and activity of superoxide dismutase (SOD) in cells were investigated. Chronic cerebral ischemia model was produced by occlusion of one carotid artery and pneumogastric nerve in mice. The step down test was adopted to investigate the effect of EDT on the memory impairment. The cerebra morphology and MDA, NO content and SOD activity in mice cerebra were detected. Results In primary rat cortical culture, 0.01-3 μmol*L-1 EDT concentration-dependently inhibited the formation of MDA and reduction of SOD activity induced by 10 μmol*L-1 H2O2. In chronic cerebral ischemia, EDT 2.5, 5 and 10 mg*kg-1 ig for 5 d greatly improved the memory impairment, reduced NO efflux and MDA content, while increased SOD activity in mice cerebra. Conclusion EDT was found to protect neurons from H2O2-induced neurotoxicity and inhibit chronic cerebral ischemia mediated injury and memory impairment in mice.
6.A case study of on the basis of tumor markers for the syndrome differentiation
International Journal of Traditional Chinese Medicine 2012;34(1):45-47
Tumor Markers(Tumor Markers,TM) as a member of the tumor microenvironment components,change with the tumor microenvironment and the functional status of the body.Chinese medicine can improve the overall regulation of tumor micro-environment impact on the TM,which to some extent,the dynamic detection of TM can be reflected in the earlier short-term medical treatment of cancer patients.Based on TM,we clarified the relationship of differentiating disease and differentiating syndrome,type of syndrome and histology pathology type for tumor.This will provide new theoretical foundation for clinical anti-tumor studies from the microcosmic scope.
