Objective To investigate the effect of type 2 diabetes mellitus (DM) on the attenuation of myocardial ischemia-reperfusion (I/R) injury by sufentanil postconditioning in rats.Methods Male pathogen-free Sprague-Dawley rats,weighing 160-180 g,were used in the study.A model for type 2 DM was established by the feeding of high-fat diet-induced insulin resistance and intraperitoneal streptozocin 35 mg/kg.DM was confirmed by blood glucose level ≥ 16.7 mmol/L one week after injection.Eighteen type 2 diabetic rats were randomly divided into 3 groups (n =6 each):DM sham operation group (DM-S group) ; DM-I/R group; DM sufentanil postconditioning group (DM-SP group).Another 18 healthy nondiabetic rats were chosen and randomly divided into 3 groups (n =6 each):nondiabetes mellitus sham operation group (NDM-S group) ; nondiabetes mellitus I/R group (NDM-I/R group) ; nondiabetes mellitus sufentanil postconditioning group (NDM-SP group).Myocardial I/R was induced by 30 min occlusion of the left anterior descending branch of coronary artery (after 30 min of equilibration) followed by 120 min of reperfusion.Sufentanil 1.0 μg/kg was injected via the right jugular vein 5 min before reperfusion in NDM-SP and DM-SP groups.MAP,SP and HR were recorded immediately before ischemia,at 30 min of ischemia and at 120 min of reperfusion and rate-pressure product (RPP) was calculated.Arterial blood samples were collected at 120 min of reperfusion for measurement of plasma cardiac troponin Ⅰ (cTnⅠ) concentration.The rats were then sacrificed for determination of the myocardial infract size.Results MAP and RPP were decreased,while the plasma cTnl concentration was increased during reperfusion in diabetic and nondiabetic rats.Sufentanil postconditioning decreased the myocardial infract size and plasma concentrations of cTnⅠ,and increased MAP and RPP during reperfusion in nondiabetic rats,but had no effect on the parameters in diabetic rats.Conclusion Type 2 DM interferes with sufentanil postconditioning-induced myocardial protection in rats.

BACKGROUND: Neural stem cells are always derived from animals, and unsuitable for human transplantation treatment. OBJECTIVE: To explore the in vitro culture methods of human embryonic striatum-derived neural stem cells, and to observe the biological characteristics. METHODS: The human embryonic striatum were separated from the embryo at a gestational age of 8-16 weeks that received induction of labor with water bag, and then the embryonic striatum was in vitro cultured in the serum-free Dulbecco’s modified Eagle’s medium. The cells were passaged after neurospheres formation, and then the cells were induced to differentiation with the Dulbecco’s modified Eagle’s medium/F12 containing 10% fetal bovine serum. RESULTS AND CONCLUSION: The in vitro cultured human embryonic striatum-derived neural stem cells grew rapidly and could express nestin. Colony formation assay showed the cel clone formation rate was 6.0%-7.0%. 5-Bromodeoxyuridine incorporation assay showed the cel proliferation rate was 37.9%. Immunofluorescence staining showed that the cells after induction and differentiation could express Tuj-1, glial fibril ary acidic protein and nestin, but not express myelin basic protein. The results indicate that human embryonic striatum-derived neural stem cells cultured in the serum-free medium can maintain their biological characteristics and have self-renewal capacity, and the cells can differentiate into the neurons and astrocytes induced by the fetal bovine serum.

Objective To evaluate the role of mitochondrial permeability transition pore (mPTP) in attenuation of myocardial ischemia-reperfusion (I/R) injury by sufentanil postconditioning in rats.Methods Sixty male Sprague-Dawley rats,aged 14-15 weeks,weighing 350-420 g,were randomly divided into 4 groups (n =15 each):sham operation group (group S),group I/R,cyclosporin A group (group CP) and sufentanil postconditioning group (group SP).Myocardial I/R was produced by occlusion of left anterior descending branch of coronary artcry for 30 min followed by reperfusion.In groups CP and SP,cyclosporin A 5 mg/kg and sufentanil 1 μg/kg were injected via the jugular vein at 5 min before reperfusion respectively,while the equal volume of normal saline was injected in group I/R.At 10 min of reperfusion,hearts were excised,the myocardial mitochondria were immediately isolated and the activity of mPTP was measured by spectrophotometry.MAP and HR were recorded at 30 min of equilibration,at 30 min of ischemia and at 120 min of reperfusion and rate-pressure product (RPP) was calculated.Arterial blood samples were obtained at 120 min of reperfusion for determination of the plasma cardiac troponin Ⅰ (cTnⅠ) concentration.The animals were then sacrificed for determination of infarct size (IS) and area at risk (AAR),and IS/AAR was calculated.The mitochondrial ultra-structure was examined with electron microscope.Results Compared with group S,the mPTP activity and plasma cTnI concentration were significantly increased,and MAP and RPP were significantly decreased in the other three groups (P ＜ 0.05).Compared with group I/R,the mPTP activity,plasma cTnI concentration and IS/ARR were significantly decreased in groups CP and SP,and MAP was significantly increased in group CP (P ＜ 0.05).Compared with group CP,MAP was significantly decreased (P ＜ 0.05),while no significant change was found in the other indexes in group SP (P ＞0.05).Significant mitochondrial swelling,and disruption and disappearance of cristae were showed in I/R group.The mitochondrial structure was more complete in CP and SP groups than that in group I/R,and the disrupted cristae were found in a small number of mitochondria in CP and SP groups.Conclusion The mechanism by which sufentanil postconditioning reduces myocardial I/R injury is related to inhibition of mPTP opening in rats.

Objective To evaluate the safety and efficacy of combining radiofrequency ablation(RFA) with arsenious acid(AA) locally to treat liver VX2 tumor in rabbits,and to explore its mechanism.Methods Twenty-eight New Zealand White rabbits with implanted liver VX2 tumors were randomly divided into four groups: control group(n= 7),AA group(n=7),RFA group(n=7),and combination(RFA+AA) group(n=7).ALT was measured before treatment and on the day 0,day 3,day 7 and day 14 after treatment,meanwhile ultrasonic(US) examination was performed.All rabbits were killed 14 days after treatment.Vascular endothelial growth factor(VEGF) was examined by immunohistochemistry,and the relationship of VEGF and gross tumor volume was analyzed.Results Combination(RAF+AA) therapy caused little damage to hepatic function but had better inhibited tumor growth.The level of VEGF in AA,RFA and RAF+AA group was lower than that of the control group(P
