70%(71.4% vs 39.3%, P0.05). Conclusion Removal of thrombus burden with the Diver CE catheter before stenting leads to improvement of myocardial reperfusion and left ventricular function in patients with AMI by a reduced risk of distal embolization and improved ST-segment resolution. Diver CE thrombus aspiration before primary PCI can be used easily and safely in the patients with AMI suffering from coronary arterial thrombosis.

ObjectiveTo compare the effects of two methods for the treatment of delayed defecation of neonatal meconium. Methods Sixty-seven neonates with delayed defecation of neonatal meconium were divided into experiment group (n=37) and control group (n=30). The former group was managed with abdominal massage followed by glycerol enema and the latter with abdominal massage followed by anus stimulation.Then the groups were compared in terms of the time for initial defecation of meconium,the volume of defecation,exhanstion time for defecation,abdominal distention and vomiting and serum bilirubin within 7 days.Result The treatment group was superior to the control one in terms of time for initial defecation of meconium,the volume of defecation, exhanstion time for defecation (P<0.05) and the incidences of abdominal distention,vomiting and serum bilirubin within 7 days were significantly lower than the control group (P<0.05).Conclusions The method of glycerol enema combined with abdominal massage is more effective for promoting defecation of neonatal meconium than the method of anus stimulation.It can reduce the incidence of abdominal distension,vomiting and pathological jaundice.

Objective To study the plasma antioxidant vitamin status in patients receiving enteral nutrition(EN) or parenteral nutrition(PN) after upper gastrointestinal surgery.Methods One hundred and twenty patients who underwent upper gastrointestinal cancer surgery were randomized into EN and PN group.The plasma vitamin A,vitamin E and ?-carotene levels pre-and post-operation and one week after clinical nutrition supplement were studied.Results Vitamin A and ?-carotene levels decreased significantly after surgery(P=0.03 and P=0.01,respectively).Vitamin E decreased 10 weeks after the nutrition,and it was significantly lower in the EN group than in the PN group(P0.05).Conclusions A decrease of antioxidant vitamins is induced by surgery and vitamin E is recommended to be given in nutrition supplement patients,especially in the patients receiving EN.

ObjectiveTo explore the effect of sustained spinal cord compression on spinal cord injury (SCI).MethodsTwenty four dogs underwent sustained spinal cord compression for 30 minutes (group A), 90 minutes (group B) and 180 min (group C) with a device designed by the authors for weight loading spinal compression, and anthor four dogs as the control group (group D) only underwent surgical operation without SCI. Cortex somatosensory evoked potentials (CSEP) were monitored during all the procedure of making model. The changes of pathologic histology, imaging and behavior examination of all animals were observed.ResultsThe lesion degrees gradually increased from group A to group C (P<0.01), and there was similar outcome in MRI imaging. The behavior improvement in group A was more significantly than that in groups B and C (P<0.05).ConclusionSustained spinal cord compression aggravates the extent of SCI process, and the decompression must be taken as soon as possible.

Objective To study the impact of physical stimulus on periosteal chondroplasia with an in- tention of reconstructing cartilage tissue that has a biomechanical function and can be created either entirely in vivo or in vitro and subsequently implanted into the patient.Methods A series of biomechanical test methods were designed in order to investigate the mechanical properties of engineered cartilage under a variety of mechanical stress stimulations.The periosteal explants were harvested from proximal medial tibias of New Zealand rabbits and secured onto poly-?-caprolactone(PCL)scaffolds.The composites(periosteum/PCL)were suspended in the spinner flask bioreactor and the spinner flask was located on the stirring machine.The stem cells were stimulated by fluid shear stress under magnetic bar stirring.Results In gross observation,the thickness and length of neo-cartilage with shear force stimulation were significantly greater than those without shear force.The direction of elongation was parallel with fluid flow direction,regardless of composite orientation.Secondary,two different zones based on various cell morphology and distribution were clearly observed.The thickness of the superficial zone was greater in samples exposed to high shear force compared with low shear force.The superficial zone protein and lubricant were found in the engineered cartilage under shear stress stimulation.Conclusion The results reveal that shear stress can not only influence proliferation and differentiation of stem cells,but also change chondrocyte morphology and increase extracellular matrix production.

AIM: Anti-atherosclerosis effects of Momordica charantia L was further studied in a New Zealand rabbit atherosclerotic model at the basis of anti-inflammation and antioxidant effects. METHODS: Animals were divided into 3 groups: normal group (normal rabbit diet), atherosclerosis group(diet containing 2% cholesterol), and Momordica charantia L group(diet containing 2% cholesterol and 1 5% sarcocarp of Momordica charantia L ). Ninety days later, all animals were sacrificed. The effect of Momordica charantia L on atherosclerosis was evaluated by measuring serum lipid and total cholesterol content of artery wall, observing fatty liver degree, aorta arteriosclerotic area, and the thickness of intima. RESULTS: The level of total serum cholesterol and LDL-C in Momordica charantia L treatment group were obviously lower than those in atherosclerosis group, so were the total cholesterol content of artery wall, fatty liver degree, atherosclerotic area, intima thickness and I/M ratio, but no significantly difference was found between the two groups in TG level. The level of HDL-C in Momordica charantia L treatment group was evidently lower than that in normal control group. CONCLUSION: Momordica charantia L has an anti-atherosclerosis action in rabbits.
