BACKGROUND: Bone morphogenetic protein in combination with hol ow porous titanium al oy can improve the affinity with surrounding bone tissues. OBJECTIVE: To observe the effects of bone morphogenetic protein 2 on growth and osteogenic differentiation of bone marrow mesenchymal stem cel s cuftured on a hol ow porous metal prosthesis scaffold. METHODS: Passage 3 Sprague-Dawley rat bone marrow mesenchymal stem cel s were directly inoculated onto a hol ow porous metal prosthesis, and then the scaffold was cultured in DMEM medium containing 0, 0.001, 0.01, 0.06 and 0.1 g/L bone morphogenetic protein 2, respectively. At 6, 12, 24 and 48 hours after inoculation, cel adhesion was detected by MTT assay. Cel osteogenic differentiation was detected by alizarin red staining at 18 days. Besides, Transwel culture was put on the scaffold, and 5x108/L bone marrow mesenchymal stem cel s were added into the upper chamber, and DMEM medium containing 0, 0.001, 0.01, 0.06 and 0.1 g/L bone morphogenetic protein 2 were added into the lower chamber to observe cel migration capability after 0, 6, 12, 24 and 48 hours culture. RESULTS AND CONCLUSION: After 6-48 hours of inoculation, different mass concentrations of bone morphogenetic protein 2 promoted adhesion of bone marrow mesenchymal stem cells in a time-dependent manner. After 18 days of inoculation, bone marrow mesenchymal stem cells induced by different mass concentrations of bone morphogenetic protein 2 changed from fusiform to polygon, and arranged in a multilayer and overlapped form. Numerous calcified nodules could be found, which were stained red by alizarin red. Additionally, within 6-48 hours of culture, bone morphogenetic protein 2 could promote the migration of bone marrow mesenchymal stem cells in a concentration-and time-dependent manner. In conclusion, bone morphogenetic protein 2 can enhance the adhesion, osteogenic differentiation and migration of bone marrow mesenchymal stem cells cultured on the hollow porous metal prosthesis.

Objective To investigate the Camtrylobacterjejuni's risk factors which were associated with the development of Guillain-Barre syndrome( GBS), the galE gene of C. jejuni strains were sequenced and the sequencing results were compared with other C. jejuni strains. Methods Selecting three GBS-asso-ciated C.jejuni strains isolated from stools of GBS patients who had been diagnosed as AMAN pattern by clin-ical and electrophysiological test from Hebei province, China. After sequencing galE gene, the results were spliced and assembled into a complete sequence by the terminals overlapped each other. The sequences of galE gene were compared with the corresponding sequences in GenBank to find the mutation and constructed the phylogenetic tree. Results The variation frequency of galE sequences of GBS-associated C. jejuni were higher than that of non-GBS-associated C. jejuni. The phylogenetic analysis demonstrated that each of the three C. jejuni strains was separately genetically closed to three strains which sequences have published in GenBank. The alignment with the related sequence of NCTC11168 shows that there are 4 same mutations in the galE gene of the three C. jejuni strains. The phylogenic tree reflected the regional feature of C. jejuni. Conclusion The probability of sequence variation of galE of GBS-associated C.jejuni is significantly higher than non-GBS-associated C. jejuni strains, the relation between the variation and GBS-pathogenesis remains to be further confirmed. The mutations found in the three C. jejuni strains established the foundation for ex-ploring the biologically characteristic of GBS-associated C. jejuni strains.

Stromal vascular fraction(SVF)are the remaining cells after removing mature fat cells in the adipose tissue. Containing a certain amount of adipose derived stem cells(ADSCs), SVF also includes many other cells, which may have the potential of promoting angiogenesis. In this review, the role of SVF in angiogenesis after fat transplantation was summarized by intensive reading relative literature in recent years. The result is that angiogenesis and fat graft revascularization are regulated by various factors: SVF promotes secretion of a diverse array of cytokines and growth which are capable of stabilizing endothelium vascular network. ADSCs have the potential of differentiating into smooth muscle cells and endothelial cells which can coroperate to form new blood vessels.
