RESUMEN

@#ObjectiveTo investigate the factors influencing pelvic traction used for prolapse of lumbar intervertebral disc (PLID).Methods200 PLID patients were treated by pelvic traction 30 min/d for 3 courses (10 days as one course).ResultsAfter treatment, therapeutic effects were prominent in 58 cases, effective in 78 cases, improvable in 34 cases, and invalid in 30 cases.ConclusionThere are definite indications in the treatment of PLID with pelvic traction. In order to gain satisfied therapeutic effect, appropriate cases should be selected for pelvic traction.

RESUMEN

<p><b>OBJECTIVE</b>To explore the way of stably inducing canine bone marrow mesenchymal stem cells (BMSCs) to differentiate into fibroblasts and myofibroblasts in vitro, and provide seed cells for fabricating tissue engineering heart valves (TEHV).</p><p><b>METHODS</b>Adult canine BMSCs were separated by a gradient centrifugation on Percoll (density 1.073 g/ml), then the cells were incubated in low-glucose Dulbecco Eagle's minimum essential medium (LG-DMEM) with 10% bovine calf serum. Cell phenotype were identified by immunohistochemistry staining. The second and third generation of BMSCs were committedly induced by conditioning culture medium, which were detected by immunohistochemistry staining. The induced-BMSCs were freezed, preserved and resuscitated after 7 d to observe the cell growth, proliferation and function.</p><p><b>RESULTS</b>BMSCs deriving from the bone marrow mononuclear cells separated by a Percoll gradient were positive expression of alpha-smooth muscle antibody, vimentin and negative expression of CD34, laminin. About (50 +/- 3)% induced-BMSCs were positive expression of laminin. Approximately (85 +/- 3)% freezed induced-BMSCs could be resuscitated. And the growth, proliferation and function were well.</p><p><b>CONCLUSION</b>BMSCs could be committedly induced to differentiate into fibroblasts and myofibroblasts in vitro. It is suitable to be the seed cells.</p>
