This study was aimed to optimize the extraction process of hyperoside from leaves ofAcanthopanax senticosusby compounding-enzyme method and orthogonal experiment. The hyperoside compound was regarded as standard and determined by HPLC. Based on the experiments of 4 factors including the enzyme amount, temperature, extraction time and PH values, the extraction process of hyperoside was determined by the orthogonal experiments and variance analysis. The results of single-factor experiments showed that different enzymes showed different effects on the enhance yield of hyperoside. The effects of different factors showed that the order of PH, neutral protease, temperature, time, pectinase, xylanase and cellulose was from strong to weak. Through orthogonal analysis, the optimum conditions were 2% pectinase, 2% xylanase, 0.5% neutral protease, and 0.5% cellulose, under the temperature of 30°C, extraction time of 10 min, and pH = 4.5. Under these conditions, the extraction rate was 1.84%. The yield was increased 107% compared with traditional process. It was concluded that the use of compounding enzyme can increase the yield of hyperoside, which possessed a lot of economic benefits.

Objective To quantitatively assess the cardiopulmonary exercise function of spinal cord injury (SCI) patients and observe the effect of aerobic exercise on cardiopulmonary function, motor function and activities of daily living. Methods From December, 2014 to June, 2016, 34 incomplete SCI patients (ASIA C and D) and 23 healthy controls received cardiopulmonary exercise test (CPET). SCI pa-tients were randomly divided into conventional rehabilitation group (n=17) and aerobic exercise group (n=17). The aerobic exercise group received aerobic exercise for four weeks. They were assessed with CPET, motor and sensory function, walking index for spinal cord injury II (WISCI II) and spinal cord independence measure (SCIM) before and four weeks after training. Results Oxygen uptake (VO2)peak, anaerobic threshold (AT), metabolic equivalent of energy (METpeak), VO2/heart rate (HR)peak, respiratory exchange rate (RER)peak, minute ventilation (VE)peak, work rate (WR)peak and systolic blood pressure (SBP)peak were lower in the patients than in the controls (t>2.714, P<0.05). VO2peak、AT、METpeak、VO2/HRpeak、WRpeak increased in the aerobic exercise group after training (t>2.431, P<0.05). METpeak and WRpeak improved in the conventional rehabilitation group after training (t>3.282, P<0.01). The scores of motor in ASIA and SCIM improved in both groups after training (t>2.985, P<0.05). Conclusion The cardiopulmonary function decreased in incomplete SCI patients, which could be improved by moderate intensity aerobic exercise.

Objective To investigate the effects of rabbit carotid artery cannula on atherosclerosis formation and β-catenin expression.Methods Fifteen 2-month-old New Zealand rabbits weighing(2.0±0.2)kg were randomly divided into three groups,high-fat diet group,left common carotid artery cannula group and left common carotid artery cannula plus high-fat diet group,5 cases in each group,and taking the right blood vessels in the left common carotid artery cannula group served as the control group.The animals were sacrificed after 9-week feeding,and the total rabbit carotid artery in each group was taken;the real-time PCR and immunohistochemistry were used to detect β-catenin mRNA and protein expression targeting in rabbit common carotid artery tissue.Results The real-time PCR results showed that the β-catenin mRNA expression in the left common carotid artery cannula group was higher than that in the control group,high fat diet group and the left common carotid artery cannula + high-fat diet group.The immunohistochemistry results showed that,except for the control group,various groups had the β-catenin protein location in the cytoplasma,moreover which in the left carotid artery cannula group and left common carotid artery cannula +high-fat diet group mainly located in the area of intimal hyperplasia.Conclusion β-catenin is highly expressed in the atherosclerotic vessel wall caused by rabbit carotid artery cannula.
