BACKGROUND: Currently, therapies for spinal cord injury include steroid pulse therapy, surgical decompression and stem cel therapy. A lot of work has been focused on stem cel therapy for spinal cord injury which has become a hot spot. OBJECTIVE: To summarize the research status and progress in induced pluripotent stem cells for treatment of spinal cord injury. METHODS: A computer-based online search of PubMed (1980-01/2011-11) was performed for articles in English using the keywords of “spine injury, induced pluripotent stem cells, IPS”RESULTS AND CONCLUSION: A total of 35 articles were included in result analysis, in which, stem cel therapy for treatment of spinal cord injury is agreed or supported. Induced pluripotent stem cells are isolated directly from the body, which solves ethical and moral issues in the transplantation of stem cells, meanwhile avoids al ograft rejection and also provides a large source of cells. Stem cel therapy for spinal cord injury is widely used in animal experiments but few in clinical application. However, stem cel therapy has a good effect in the animal experiments, and shows a higher safety. The existing problems of induced pluripotent stem cells to treat spinal cord injury mainly include immature differentiating method of induced pluripotent stem cells and more complications. Therefore, induced differentiation and security of induced pluripotent stem cells for treatment of spinal cord injury wil become a research key.

Objective To evaluate the safety of endoscopic ligation of gastric and colic full-thickness wall with nylon loops.Methods Endoscopic ligation of full gastric and colic wall with detachable nylon loops, assisted by laparotomy, were performed in 4 dogs.Ligation healing was assessed on 3, 7, 10and 17 days after the procedure.Results All animals recovered after the procedure, without any clinical signs of infection or hemorrhage.Postoperative examination did not reveal gastric or colonic perforation, or local abscess.Loop ligature showed ulcer-like lesion.Histopathology revealed muscularis propria disruption, granulation tissue bridging the site of ligation and formation of scar tissue.Regenerative mucosa coyered the surface of the ligature completely 17 days after the operation.Conclusion Endoscopic ligation of gastric and colic full-thickness wall with detachable nylon loops is safe.Its application can be extended to other fields.

Purpose: Set up a new technique to reproduce the cavitation effect in the process of brain deceleration impact Methods: A transparent physical brain model with tiny air bubbles was built and loaded on an upright brain deceleration impacting moveable platform. Then, in the high strength lighting circumstance, the moveable platform was made to free fall from a height of 40cm and impacted on a fixed platform, and the whole deceleration impacting process was recorded by a high-speed video camera. Using the serial pictures analysing software, the volume and mean pressure change of the air bubbles were calculated and the cavitation effect of the brain tissue during the impact was studied. Results: The volume of the air bubble in the contrecoup site increased obviously in the impacting process, the volume of the air bubble in the coup site decreased in the impacting process and the volume change of the air bubble in the middle site was not evident enough in the impacting process. Conclusion: The results proved the negative pressure and the cavitation phenomenon in the contrecoup site. The experiments explicitly and directly showed the cavitation effect in the contrecoup site during the decelerating impact It was helpful to better understand the distribution characters of the dynamic stress of the brain tissue in the brain decelerating impact in a certain extent, and it could also provide some methods and experimental foundation to clarify the mechanical mechanism of the brain contrecoup injury which was often taken place in traffic accidental injury. Besides, the methods were of significance to research the biomechanism, diagnosis and prevention of the brain deceleration impacting injury.

BACKGROUND:Emerging evidence shows that rs6756667 SNP EPAS1-A alele is beneficial for, however, the GG genotype is detrimental for adaptation to high-altitude hypoxia in Tibetan populations.
OBJECTIVE:To compare the EPAS1 gene rs6756667 polymorphism between Tibetan elite endurance athletes and Tibetan non-physical education major students and analyze its relationship to aerobic exercise capacity.
METHODS:Forty Tibetan athletes in Ganzi Tibetan middle and long distance athletes sports teams (athlete group) and forty Tibetan non-physical education major students in Ganzi (student group) were included in this study. The EPAS1 gene rs6756667 polymorphic loci were determined using PCR high-resolution melting analysis. The genetic polymorphism data from this study were compared withthe data from previous studies. Increase values of bone mineral density in the pelvis, upper and lower limbs were determined by dual-energy X-ray absorptiometry.
RESULTS AND CONCLUSION:There were significant differences in the genotype frequencies of EPAS1 rs6756667 AA, AG and GG between student group(50%, 47.5%, 2.5%)and athlete group(72.5%, 27.5%, 0;P< 0.05). The genotype frequency of GG was significantly increased in student group compared with athlete group (P< 0.05). There were differences in the frequencies of A alele and G alele between both groups (95%CI:0.459-0.908,P=0.011).Bone mineral density inthe pelvis, upper and lower limbs and whole body was significantly higher in student group than athlete group (P< 0.05). These findings suggest that EPAS1 gene rs6756667 polymorphism is related to aerobic capacity of Tibetan elite endurance athletes. rs6756667 SNP EPAS1-A alele is beneficial for, however, the GG genotype is detrimental for adaptation to high-altitude hypoxia in Tibetan athletes.

Objective to research the mechanical style(compressive or tensile force)of the key site of brain tissue in brain deceleration impact.Method a transparent physical brain model with air bubbles was built and loaded on an upright brain decaler ation impacting expedmentel platform.Then,the moveable platform was made a free fall from a height of 400mm and impacted on the fixed platform,and the whole deceleration impacting process was recorded by a high-speed video camera.Using the serial pictures analyzing Software,the length change of the long ads(vertical to the impacting direction)and the short axis(in the impacting di-rection)of the air bubbles were analyzed and calculated.Result the length change of the long axis of air bub-ble with in site coup was smallerthan the absolute value of that of the short axis;while with the air bubble in the contrecoup site,the length change of the long axis was bigger than the absolute value of the short axis.Conclusions the results showed that the air bubble in the coup site mainly suffered from the tensile force vertical to the impacting direction and the air bubble in the contrecoup site mainly suffered from the compres-sive force in the impacting direction.Since the propeny of tensile resistance of the brain tissue is inferior to the property of compressive resistance of the brain tissue, the injury is often easier to occur in the contrecoup site than in coup site. The results were of significance to the research of biomechanical mechanism, diagnosis and prevention of the brain deceleration impacting injury.

Human rhinoviruses (HRVs) are the causative pathogens in more than half of viral upper respiratory tract infections. Currently, no antiviral agents that are active against HRVs are available for clinical use. Because only higher primates are susceptible to HRVs, the screening of new drug is most commonly based on the cell line model. In this study, isolated rabbit airway smooth muscles (ASM) tissue model has been established, and the airway responsiveness with different treatment has been examined. Relative to control tissues, the maximal constrictor (Tmax) response to ACh increased significantly 150% in ASM inoculated with HRV, and relaxation to isoproterenol has been attenuated to 63%. And the abnormal responsiveness can be inhibited in presence of pretreatment with several new compounds which have been exhibited effective anti-HRV activity on cell lines. The results demonstrate that the established ASM model will be applied to screening the anti-HRVs drugs.
