ABSTRACT
Objective To study the clinical use of intramedullary interlocking nail in treatment of femoral and tibial fractures. Methods104 cases of femoral or tibial fractures were treated with intramedullary interlocking nails.Results The close and open reduction fractures had healed 6 10 and 8 12 weeks after surgery, and the fixation nails were taken out after 48 weeks. No broken nail, no delayed or nonunion, no infection, no fat embolism, no stiff joint occurred, All cases were followed up and the average following was 20 months without fracture.Conclusion The intramedullary interlocking nail had obvious advantage of reliable fixation, rotation and separation prevention, no need of external fixation support, high rate of fracture healing and allowance of early walk without support.
ABSTRACT
[Objective] Pharmacological actions of polysaccharides from Fructus Rosae Roxburghii (PFRR) were investigated to supply evidence for its source development and application. [Methods] With ginsenoside as the positive control, the effect of PFRR on the swimming time and the survival time under the conditions of normotensive hypoxia, hyperther-mia and hypothermia in mice were observed. Phagocytic function of macrophage and serum hemolysin level were also detected. [Results] In PFRR group, the swimming time and the survival time under the above conditions were both prolonged, phagocytic percentage and phagocytic index increased and time at 50% hemolytic concentration prolonged ( P
