RESUMO
Objective To investigate the effects of low intensity pulsed ultrasound ( LIPU ) on articular car-tilage injury in rabbits. Methods Ten adult New Zealand white rabbits with bilateral, full-thickness osteochondral defects in the cartilage surfaces of intercondylar fossas were used as model. The left knees in these rabbits treated with LIPU were used as experimental group. The right knees treated with sham intervention were used as controls. All the rabbits were sacrificed at the 8th week postoperation for gross appearance grading, histological grading and semi-quan-titation of proteoglycan in the repairing tissue. Results Compared with controls, defects treated with LIPU im-proved significantly as shown by gross appearance grades, histological grades and optical density of toluidine blue at the 8th week postoperation (both P <0.05). Conclusion LIPU could accelerate repairing of articular cartilage in-jury.
RESUMO
Objective To explore the features and treatment methods of osteoporotic vertebral compression fracture of elderly patients with cardiopulmonary diseases. Methods 18 cases of osteoporotic vertebral compression fracture of elderly patients with cardiopulmonary diseases teated by percutanteous vertebroplasty(PVP), and VAS(visual analogic scale) and mobility ability were measured before and after treatment. Results All 18 patients were punctured and operated successfully. The preoperitive and postoperative VAS was 7.6?1.2 and 3.7?1.3, respectively. There was obvious pain relief after operation (P
