Objective To observe the clinical efficacy of vacuum sealing drainage(VSD) in the treatment of large-area wound infection of earthquake casualty after amputation.Methods Seven patients with large-area wound infection of earthquake casualty after amputation received sustained VSD.Results After VSD for 7~26 days,with an average of 13 days,the wound infection in the 7 patients was controlled.No systemic toxicity was found.The result of wound bacterial culture was negative.Of the 7 patients,4 received phase Ⅱ suture,3 received phase Ⅱ skin graft,and all of the grafted skin survived.Conclusion Vacuum sealing drainage exerts certain effect in the treatment of large-area wound infection of earthquake casualty after amputation.

Objective To observe the therapeutic effect of external application and oral use of Herba Seu Radix Violae Japonicae(HSRVJ) for the treatment of chronic osteomyelitis.Methods Sixty chronic osteomyelitis were randomized into the treatment group and the control group.The two groups received conservative routine antibiotic treatment.The treatment group received external application and oral use of HSRVJ additionally.Seven days constituted one treatment course,and the treatment lasted 6 courses.The changes of erythrocyte sedimentation(ESR) and C-reactive protein(CRP) were compared in the two groups before treatment and every 2 courses.Meanwhile,the clinical cure rate and the total effective rate were observed in the two groups.Results The cure rate was 46.67% and the total effective rate was 86.67% in the treatment group,and was 20.00% and 63.33% in the control group respectively.ESR and CRP decreased gradually every 2 courses in the two groups(P
