Objective To observe the effects of 8-week aerobic exercise on skeletal muscle glycogen content and exercise endurance and investigate the possible mechanism in rats with chronic heart failure. Methods 30 Sprague-Dawley rats were submitted to heart failure sedentary (H) group, heart failure traning (HT) group and sham operation (S) group. The heart failure model was established with coronary artery ligation. HT group performed an 8-week treadmill running. The skeletal muscle glycogen content was determined with anthracenone, exercise endurance with exhaust duration of graded exhausted exercise test, glucose uptake rate, activity of glycogen synthase (GS) and glycogen phosphorylase (GP) with radicisotope, protein expression of total GS, phospho-GS (p-GS), total GP and phospho-GP (p-GP) with Western Blotting. Correlation analysis was conducted between glycogen content and exhaust duration. Results The skeletal muscle glycogen, exhaust duration, glucose uptake rate, GS activity and p-GP protein reduced (P<0.05), while serum insulin, GP activity and p-GS protein raised (P<0.05) in the H group compared with those in the S group. The skeletal muscle glycogen, exhaust duration, glucose uptake rate, GS activity and p-GP protein increased (P<0.05), while serum insulin, GP activity and p-GS protein decreased (P<0.05) in the HT group compared with those in the H group. There was positive correlation between glycogen content and exhaust duration (P<0.05). Conclusion Prolonged aerobic exercise enhanced skeletal muscle glycogen content and exercise endurance in rats with chronic heart failure, which may be related to the improvement of insulin sensitivity, muscle glucose uptake, increase of glycogen synthesis and decrease of glycogen breakdown.

Objective:To construct the finite element models of maxillary central incisor and the simu-lations with crown lengthening surgery and post-core restoration in management of different crown-root fracture types, to investigate the stress intensity and distributions of these models mentioned above, and to analyze the indications of crown lengthening from the point of view of mechanics. Methods:An extrac-ted maxillary central incisor and alveolar bone plaster model were scanned by Micro-CT and dental impression scanner ( 3shape D700 ) respectively. Then the 3D finite element models of the maxillary central incisor and 9 simulations with crown lengthening surgery and post-core restoration were construc-ted by Mimics 10. 0, Geomagic studio 9. 0 and ANSYS 14. 0 software. The oblique static force (100 N) was applied to the palatal surface ( the junctional area of the incisal 1/3 and middle 1/3 ) , at 45 degrees to the longitudinal axis, then the von Mises stress of dentin, periodontal ligament, alveolar bone, post and core, as well as the periodontal ligament area, were calculated. Results:A total of 10 high-precision three-dimensional finite element models of maxillary central incisor were established. The von Mises stress of models: post >dentin >alveolar bone >core >periodontal ligament, and the von Mises stress increased linearly with the augmentation of fracture degree ( besides the core) . The periodontal ligament area of the crown lengthening was reduced by 12% to 33%. The von Mises stress of periodontal ligament of the B2L2c, B2L3c, B3L1c, B3L2c, B3L3c models exceeded their threshold limit value, respective-ly. Conclusion: The maxillary central incisors with the labial fracture greater than three-quarter crown length and the palatal fracture deeper than 1 mm below the alveolar crest are not the ideal indications of the crown lengthening surgery.

Objective To compare tbe efficacy of conventional therapy,psychotherapy,serotonin reuptake in- hibitor,and psychotherapy combined with serotonin reuptake inhibitor in rehabilitating nerve function in the treatment of post-stroke depression.Methods One hundred and twenty patients with post-stroke depression were divided into a control group(A),a group treated with serotonin reuptake inhibitor (B),a psychotherapy group (C) and a group in which psychotherapy was combined with serotonin rcuptake inhibitor(D).These groups were graded with the SDS for the degree of their depression and with the MESSS for their muscle strength before andafter treatment.Results The anti-depression therapies showed significantly different effects in improving depression.After eight weeks,group D showed significantly less depression than the others.However,muscle strength did not show statistically significant differences until twelve weeks,when group D again showed better progress than the others.Conclusion Psychothera- py combined with serotonin reuptake inhibitor can promote the rehabilitation of nervous function-after stroke.

OBJECTIVE:To put forward the tentative idea of the application of the access and benefit-sharing regime in the field of Chinese medicine.METHODS:The existing problems of protecting biological diversity in the field of Chinese medicine and what problems the access and benefit-sharing regime could solve were analyzed.RESULTS & CONCLUSION:Our preliminary idea for applying access and benefit-sharing regime in the field of Chinese medicine is to set up a special department for negotiation,identify the rights and subject,construct registration system and informed consent procedure,improve the source disclosure system and add the benefit-sharing regulation.

Recently surface-enhanced Raman spectroscopy (SERS) has been widely used in physics, chemistry and bio-medical science.Due to its high sensitivity and specificity,SERS is often used to detect changes in serum components in humans.Various biomolecules in human serum, such as proteins, lipids and nucleic acids, have their own distinctive raman spectroscopy so that different raman shift, band intensity and width reflect different metabolic abnormalities of cells at the molecular level in human serum.In this paper we described the general situation of SERS and summarized the latest research progress in a variety of diseases of human serum.Prospects of developmenls are also outlined.
