BACKGROUND:White blood cells involved in the inflammatory response play an important role in deep vein thrombosis.E-selectin mediates the initial process of white blood cell and vascular endothelial cell attachment during inflammation.OBJECTIVE:To investigate the relationship between deep venous thrombosis(DVT) and plasma E-selectin.DESIGN,TIME AND SETTING:Completely random design and linear correlation analysis were performed at Department of Vascular Surgery,First Affiliated Hospital of Chongqing Medical University and Clinical Diagnostic Laboratory of Chongqing Medical University from September to December 2007.PARTICIPANTS:Twenty-seven cases of deep vein thrombosis,16 males and 11 females with an average age of(57 ? 15) years,were selected,who attacked within 3 days or with aggregated condition.METHODS:Blood samples were obtained at the admission of the patients.After 72 hours,a second specimen was obtained,defined by thrombolysis and anticoagulant therapy.Determination of plasma E-selectin by ELISA and the blood coagulation abilities and platelet count of the 1st blood samples were performed,including part-time activation thromboplastin,prothrombin time,and plasma fibrinogen.MAIN OUTCOME MEASURES:E-selectin levels before and after treatment,blood coagulation abilities before treatment,platelet determination and E-selectin related analysis.RESULTS:No acute pulmonary embolism occurred in 27 cases of deep vein thrombosis during the treatment.One case underwent routine Forgart of thrombectomy catheter,and of the other 26 cases,15 were significantly improved,and 11 were not improved after 72 hours.Plasma E-selectin levels significantly decreased after thrombolysis,anticoagulant therapy in deep vein thrombosis patients with clinical remission(P = 0.001),but the plasma E-selectin levels were increased in those with no remission(P = 0.003).E-selectin levels and platelet count of deep vein thrombosis in patients before treatment showed no correlation(r =-0.113,P = 0.576),and were not related to fibrinogen content(r =-0.050,P = 0.802),or part-time activation thromboplastin(r=-0.046,P=0.822),and prothrombin time(r=-0.080,P=0.690).CONCLUSION:Plasma E-selectin levels are positively related to deep vein thrombosis severity.

Objective To investigate the effects of electroacupuncture at meridian point on the mRNA expressions of corticotropin-releasing factor (CRF) and corticosteroid (CORT) in the hippocampus after cerebral ischemia reperfusion in rats.MethodsA total of 150 SD rats were randomly divided into 5 groups by random number table method: normal control group, sham operation group, model group, meridian point electroacupuncture group and non-meridian point electroacupuncture group, with 30 rats in each group. A model of focal cerebral ischemic reperfusion was induced using the modified intraluminal thread method. In the meridian point electroacupuncture group, at 6 h after cerebral ischemia reperfusion, acupuncture “LI11” on both sides, bilateral “ST36”, “GV20”, ”GV16” daily for 7 d. The neurological deficits were evaluated 1 d, 3 d, and 7 d after cerebral ischemia reperfusion, and then all rats were sacrificed and the hippocampi were harvested. The mRNA expressions of CRF and CORT in the hippocampus were determined by quantitative real-time PCR.ResultsThe mRNA expressions of CRF (1.122 ± 0.249, 1.190 ± 0.666, 0.454 ± 0.612 in the model group; 0.021 ± 0.049, 0.021 ± 0.027, 0.035 ± 0.005 in the sham operation group) and CORT (0.917 ± 0.113, 1.024 ± 0.290, 0.709 ± 0.055 in the model group; 0.016 ± 0.013, 0.016 ± 0.006, 0.043 ± 0.006 in the sham operation group) in the hippocampus 1 d, 3 d, 7 d after cerebral ischemic reperfusion were significantly increased in the model group compared with the sham operation group (all P<0.01). The mRNA expressions of CRF (0.424 ± 0.104, 0.339 ± 0.476, 0.095 ± 0.021) and CORT (0.377 ± 0.073, 0.138 ± 0.025, 0.158 ± 0.010) in the hippocampus 1 d, 3 d, 7 d after cerebral ischemic reperfusion were significantly decreased in the meridian point electroacupuncture group compared with the mode1 group (allP<0.01). The neurological deficits scale 1 d, 3 d, 7 d after cerebral ischemic reperfusion were significantly decreased in the meridian point electroacupuncture group compared with the mode1 group (1.83 ± 0.75, 1.50 ± 0.55 and 1.17±0.41 in the meridian point electroacupuncture group; 2.50 ± 0.84, 2.33 ± 0.52 and 1.67 ± 0.52 in the model graoup; allP<0.01). Conclusion Electricacupuncture at meridian point can reduce the mRNA expressions of CRF and CORT in the hippocampus, and improve neurological deficits after cerebral ischemia reperfusion in rats.

95 children with cerebral palsy (CP), aged from 4 months to 5 years, were treated with Bobath,Vojta and Wilson therapies. The developmental scores of motor function was evaluated. The motor function of children suffering from CP was severely retarded before the treatment. The average score is 1. 28 ± 0. 34 permonth, and they were singificantly improved after the treatment with 8 scores in average per month.

Objective To investigate the gene expression of Chk1 gene in cerebrum after brain ischemia-reperfusion, trying to provide evidence to elucidate the molecular mechanism of brain injury.Methods Eighty-five male Wistar rats were divided into 3 groups.Group Ⅰ served as normal control.In group Ⅱ (non-ischemia group) animals underwent the whole experimental procedures except the occlusion of the bilateral vertebro-arteries and common carotid arteries.In group Ⅲ (ischemia-reperfusion group) animals were further divided into 3 subgroups according to the duration of ischemia: 10min, 30min and 60min.Each subgroup was again further divided based on the duration of reperfusion: 30min,2h and 6h.The cerebrum was immediately removed from rats after complete brain ischemia-reperfusion. The RNA was isolated and the reverse-transcription-polymerase chain reaction (RT-PCR) was carried out .The cDNA was analyzed by automatic system and the parameters were assessed to define the status of Chk1 mRNA expression in different ischemia and reperfusion groups.Results The quantity of Chk1 mRNA expression in the cerebral cortex of normal adult rat was about half of the glyceraldehyde-3-phosphate-dehydrogenase. When reperfused for 30min, 2h or 6h following 10min, 30 min cerebral ischemia and reperfused for 30min or 2h following 60 min cerebral ischemia, the expression of Chk1 mRNA was not significantly different from that in non-ischemia group.Only reperfused for 6h following 60 min cerebral ischemia, Chk1 mRNA expression decreased significantly.Conclusions The results indicate that Chk1 gene might be involved in molecular mechanism of cerebrum damage during complete global brain ischemia-reperfusion.
