Effect of rhBMP-2 and Osteogenic Revulsants on Proliferation and Differentiation of Bone Marrow Stromal Cells in Rats / 华中科技大学学报（医学）（英德文版）

The effects of recombinant human bone morphogenetic protein-2 (rhBMP-2) and osteo- genic revulsants alone or in combination at different time points and in different dosages on prolifera- tion and osteogenesis of bone marrow stromal cells (BMSCs) in SD rats were investigated. Rat BMSCs were cultured in vitro and induced by rhBMP-2 in different dosages (10, 50, 100 and 2013μg/L) alone or in combination with osteogenic revulsants. MTT colorimetric assay was used to evaluate The proliferation, activity of alkaline phosphoric (ALP) and osteocalcin were measured at 3rd, 6th, 9th, 12th day respectively. The results showed that rhBMP-2 and osteogenic revulsants could promote the differentiation of BMSCs towards osteoblast phenotype. The proliferation of BMSCs could be enhanced by rhBMP-2 in a dose-dependent manner. The expression of osteoblast phenotype was significantly higher by using both of them than by using them alone, which was veri- fied by the activity of ALP and osteocalcin. It was suggested that the combined use of rhBMP-2 and osteogenic revulsants could promote the proliferation and simultaneously induce and maintain the expression of osteoblast phenotype of BMSCs in rats.

Magnetic stimulation accelerating rehabilitation of peripheral nerve injury / 华中科技大学学报（医学）（英德文版）

The effect of magnetic stimulation (MS) on sciatic nerve injury was observed. After sciatic nerve was crushed in 40 Sprague Dawley (SD) rats, one randomly selected group (group D) was subjected, from the 4th day post-operatively to 3 min of continuous 70% of maximum output of MS daily for 8 weeks. The other group (group E) served as a control group. The nerve regeneration and motor function recovery were evaluated by walking track analysis (sciatic function index, SFI; toe spreading reflex, TSR), electrophysiological, histological and acetylcholineesterase histochemistry. The SFI in the group D was greater than in the group E with the difference being statistically significant (P < 0.01). TSR reached its peak on the 4th day in the group D and on the 10th day in the group E respectively. The amplitude and velocity of MCAP and NCAP in the group D was greater than in the group E with the difference being statistically significant (P < 0.01), while the latency and duration of MCAP and NCAP in the group D were less than in the group E with the difference being also statistically significant (P < 0.01). Histological examination showed the mean axon count above the lesion for thick myelinated fibers (> 6.5 microns) in the group D was greater than in the control group with the difference being statistically significant (P < 0.01), while the mean axon count below the lesion for thick myelinated fibers was less than that in the group E with the difference being statistically significant (P < 0.01). The mean axon count above the lesion for thin myelinated fibers (2-6.5 microns) in the group D was greater than that in the group E with the difference being statistically significant (P < 0.05), while the mean axon count below the lesion for thin myelinated in the group D was greater than that in the group E with the difference being statistically significant (P < 0.01). Acetylcholine esterase examination showed that the MS could significantly increase the number of the motor neurons. There was no significant difference in the number of the motor neurons between the treatment side and the normal side (P > 0.05). It can be concluded that MS can enhance functional recovery and has a considerable effect in the treatment of the peripheral nerve injury.

Biomechanische Untersuchungsergebnisse über die verbesserte Verankerung von Pedikelschrauben mit resorbierbarem / 华中科技大学学报（医学）（英德文版）

Die Prim?rstabilit?t von Pedikelschrauben im Knochen h?ngt in hohem Masse von der Knochendichte ab. Die Augmentation mit Zement ist ein klinisch einsetzbares Verfahren, um die Schrauben-Verankerung im osteoporotischen Knochen zu verbessern.In dieser Studie wurde eine neuartiges resorbierbares Knochenersatzmaterial (α-BSMTM) für diese Augmentation benutzt. Biomechanische Testungen wurden in vitro bei 16 Lendwirbelkorpern (L3-L5) aus 6 Individuen(75,2±13,7 Jahre) durchgeführt. Vor der biomechanischen Testung wurde bei allen Pr?paraten die trabekul?re Knochendichte mittels pQCT gemessen und beide Pedikel mit USS-Pedikelschrauben (5,0 mm × 45 mm) besetzt, von welchen eine mit α-BSMTM augmentiert war. Beim axialen Auszugstest wurden die maximale axiale Auszugskraft (F-max) sowie die Energieaufnahme bestimmt. Der Medianwert der F-max stieg beim Auszugstest durch die Zementierung mit α-BSMTM um 80 % von 370 N (ohne Zement) auf 665 N (mit Zement). Die Energieaufnahme bis zum Erreichen der F-max (E-F-max) und bei Dislokation bis 2,0 mm (E-2 mm) steigerte sich ebenfalls um 83 % und 68 %. Die Unterschiede waren signifikant.
