RESUMO
ive] To explore a new method of evaluating the healing of fractures. [Methods] Self-con trolled trial was applied. Bone mineral density ( BMD) of fracture end (region 3, R 3 ) and its neighboring proximal and distal regions ( R 2 and R 1 respectively) in 126 cases of fracture of lower end of radius was deter mined by dual-energy X-ray absorptionmetry. [Results] BMD of R3 elevated as compared with that of R 2 and R1 (P
RESUMO
ObjectiveTo report the clinic result of bone and skin defects of forefoot and defects of forefoot treated by allograft and complex flap of crural artery with nerve and periosteum. Methods Allograft and complex flap with periosteum of tibien were used to repair bone and skin defects of forefoot in 9 cases ,in which the defects of forefeet were reconstructed by sequential connection with the complex flaps of tibialis posterior artery with saphenous nerve and periosteum in 2 cases. Results Six cases were survived completely;distal part in surface layer of flaps were necrosis partly in 3 cases and healed by dressing. After operation ,the repaired bone and joint showed normal position and recovered arcus pedis transversalis and arcus pedis longitudinalis by X-ray films. The patients were followedup from 3 months to 3 years,all grafted allograft had showed bone union and hadnt showed complications such as absorption,infection and repulsion. The injuried foot was restored its weight-bearing and walking functions and obtained a satisfactory contour. After operation,sensory recovery of foot occurred about 2 months. ConclusionUsed allograft is easy to do and recover arcus plantaris. The reverse complex flaps of tibialis anterior artery with periosteum have advantages as follow :the advoidance of influencing blood supply of injuried foot ,advancing symphysis ,short treatment course,simply procedure ,walking functions recovered ,good appearance and sensation.
RESUMO
Objective To study the blood_flow_activating and blood_stasis_removi ng actions of Qushang Tablet (QT) and its safety. Methods Thirty rats were randomly allocated to Group A (normal control), Group B (models control) and G r oup C (treated with QT). Rat models with traumatic blood_stasis syndrome were in duc ed by the bruise of falling iron hammer. Effects of QT on blood rheology of rat model were studied. Acute and chronic toxic effect of QT was also studied. Res ults QT had obvious effect on blood rheology of rat model and could improve th e concentration, viscosity, aggregation and coagulability of blood. No acute and chronic toxic effect of QT was found. Conclusion QT exerts obvious blood_fl ow_activating and blood_stasis_removing actions and is safe to be applied in cli nic.
