Objective To investigate the dosage, efficacy and safety of intravitreal injection of plasmin in producing posterior vitreous detachment (PVD), and the possible role of plasmin in degrading adhesion glycoproteins of inner limiting membrane (ILM). Methods Twenty eyes of young human cadavers within 24 hours after death were divided into 4 groups that received 0 1 ml balanced salt solution (group 1) as control, 1 (group 2), 2 (group 3), or 3 (group 4) U of human plasmin. Optical and transmission electron microcopies were performed to examine the ultrastructure of the vitreoretinal interface. Electron immunocytochemical techniques were carried out on ILM to estimate the content of fibronectin (FN) and laminin (LN). Flow cytometry was used for cell viability analysis of variance (ANOVA) and Tukey test was employed for statistical analysis. Results Microscopy demonstrated that plasmin especially in group 4 cleaved the attachment of the vitreous collagen fibrils to the ILM with no evident damage to the inner retina. The content of LN, FN in ILM decreased with injection of plasmin (group 3 and 4 had statistical significance from control group for FN, P

BACKGROUND:Long course of treatment and complications limit the extensive application of distraction osteogenesis, which cannot meet the clinical requirements. OBJECTIVE:To investigate the effect of general administration of eucommia alcohol extract on new bone regeneration based on the rabbit model of mandibular distraction osteogenesis. METHODS:Twenty-four New Zealand white rabbits were randomly divided into experimental group and control group. Unilateral mandibular distraction osteogenesis model was established by 1 mm/12 h distraction protocol. During the distraction period, the rabbits in the experimental group were intragastricaly administered with eucommia alcohol extract and the control animals received the same amount of physiological saline, respectively. Six weeks later, the animals were sacrificed for osteogenic testing. RESULTS AND CONCLUSION: New bone formation was observed in the distracted gap in both groups. However, the amount, mineralization and biomechanical strength of new regenerated bone in the experimental group were obviously greater than those in the control group by histological observation, dual energy X-ray absorptiometry, micro-CT and biomechanical test. General administration of eucommia alcohol extract can markedly promote distraction osteogensis in rabbit mandibular osteodistraction.

Objective To evaluate the impact of hydrogen sulfide signal system during the process of rat bone marrow-derived mesenchymal cells osteogenesis under tensile stress. Methods After the H2S signal system of cell rooms regulated by tool drugs (Group A with propargylglycine;Goup B with PBS;Group C with GYY3147), 4 000 μ strain tensile stress were applied on rat BMMCs by four-point bending apparatus for 60 minutes. Four hours later, the H2S signal system and cystathionine-γ-lyase were detected. Meanwhile, the change of the alkaline phosphate, osteocalcin, procollagen typeⅠN-terminal propeptide, and runt-related transcription factor 2 mRNA level were also examined to evaluate the osteogenic ability. Results With the increase of H2S expression, the osteogenic capacity gradually increased, while the osteogenic capacity was compromised after the endogenous cystathionine-γ-lyase was inhibited. Conclusion The H2S signal system plays an important role during BMMCs osteogensis under tensile stress. The up-regulation expression of H2S may promote osteogenesis during distraction osteogenesis.
