BACKGROUND:Maxilofacial bone and periodontal tissue defect is one of the important diseases that affect human functionality and aesthetic appearance, and bone tissue engineering becomes the main means to repair maxilofacial and periodontal tissue defects. Currently, the basic mode is constructed by the combination of co-culture of seed cels and cels, scaffolds and micro-environment. Pre-vascularization and rapid osteogenesis of tissue-engineered bone can reduce implant necrosis and absorption, and improve repair success rate. OBJECTIVE:To summarize the new progress of bone tissue engineering used in the oral and maxilofacial and periodontal tissue in the past 5 years. METHODS:CNKI database and PubMed database from 2010 to 2015 were searched using the keywords of “oral and maxilofacial, bone tissue engineering, bone regeneration, vascularization, genetic modification, seed cels, support material, microenvironment” in Chinese and English, respectively. After elimination of independent and repetitive studies, 68 articles were included in result analysis. RESULTS AND CONCLUSION: The tissue-engineered bone has achieved tremendous progress in the repair of oral and maxilofacial and periodontal tissue defects. The three-dimensional scaffold with gene-modified seed cels can effectively promote the vascularization, improve the osteogenic effect and increased the probability of success in mandibular defect repair. In addition, tissue-engineered bone implantation into the alveolar ridge defects or fresh extraction fossa can effectively restore and preserve alveolar ridge height and width, to ensure a good bone condition for subsequent restorative treatment. After the implantation of tissue-engineered bone, different external environmental stimuli could be loaded at defect sites, and the extracelular matrix components or signal pathway could be adjusted to change the process of vascularization. Vascularization is a premise condition for the establishment of an effective blood circulation to ensure the success of scaffold implantation.

Aim: To establish a method for the determination of pantoprazole sodium and its related substances. Methods: A column packed with octadecylsiance bonded silica gel (250 mm × 4. 6 mm, 5 pjn) was used. The 0. 01 mol/L monopotassium phosphate solution( adjusted with phosphoric acid to pH 7. 0) -acetonitrile were adopted as the mobile phase, a gradient elution was programmed as follows: 0→30 min(90:10-60:40), 30→45 min(60: 40→15: 85); the detection wavelength was 289 nm; the column temperature was 40 ℃; the flow rate was 1. 0 mL/min. Results: Pantoprazole sodium, the intermediates and its related substances could be well separated. A good linear relationship was obtained over the range of 6. 96-48. 72 μg/mL( r =0. 999 9). The limit detection and quantisation of pantoprazole sodium were 8.51 ng and 17.0 ng, respectively. Conclusion: This method can be applied to control the related substances of pantoprazole sodium and determine pantoprazole sodi-um.

BACKGROUND:Exercises play an important role in the recovery of neurological function after stroke. Few studies concerned the amount of exercise in rats after stroke. Hippocampus is strongly associated with cognitive function, but no reports addressed the expression of repulsive guidance molecule A in the rat hippocampus after ischemia and reperfusion. OBJECTIVE:To explore the effects of exercise on repulsive guidance molecule A expression in the hippocampus on the ischemic side in rats after cerebral ischemia-reperfusion injury. METHODS:120 Sprague-Dawley rats were equal y and randomly divided into normal group, sham-operation group, and 7-, 14-, 28-day model groups. The model of right cerebral ischemia-reperfusion injury was induced by ligation with nylon monofilament in rats of 7-, 14-, 28-day model groups. Low exercise group received treadmil training of 5 m/min, 5 minutes;7 m/min, 5 minutes;9 m/min, 20 minutes. Moderate exercise group received treadmil training of 8 m/min, 5 minutes;10 m/min, 5 minutes;13 m/min, 20 minutes. High exercise group received treadmil training of 8 m/min, 5 minutes;11 m/min, 5 minutes;20 m/min, 20 minutes. RESULTS AND CONCLUSION:Repulsive guidance molecule A mRNA and protein expression was highest in the ischemic side of the hippocampus in the 7-day model group without excercise. Moreover, repulsive guidance molecule A relative expression gradual y reduced over time. Compared with non-exercise, repulsive guidance molecule A mRNA and protein expression significantly decreased in the 14-and 28-day model groups during moderate exercise (P<0.05), but repulsive guidance molecule A mRNA and protein expression increased during high exercise. Above data confirmed that moderate exercises could decrease repulsive guidance molecule A expression in the affected side of the hippocampus of rats with cerebral ischemia-reperfusion injury.
