RESUMO
Objective@#This study aims to analyze factors associated with lymphovascular space invasion (LVSI) and evaluate the prognostic significance of LVSI in Chinese endometrioid endometrial cancer (EEC) patients. @*Methods@#Five-hundred eighty-four EEC patients undergoing surgery in our center from 2006 to 2016 were selected for analysis. Univariate analysis and multivariate logistic regression were used to examine relevant factors of LVSI. To evaluate the prognostic role of LVSI, survival analyses were conducted. In survival analyses, both multivariate Cox regression and propensity score matching were used to control the confounders. @*Results@#The incidence of LVSI was 12.16% (71/584). Diabetes history (p=0.021), lymph node metastasis (p=0.005), deep myometrial invasion (p<0.001) and negative PR expression (p=0.007) were independently associated with LVSI. Both Kaplan-Meier method and univariate Cox regressions showed LVSI negative and positive cases had similar tumor-specific survival (TSS) and disease-free survival (DFS). After adjusting for the influence of adjuvant therapy and other clinicopathological factors with multivariate Cox regressions, LVSI still could not bring additional survival risk to the patients (p=0.280 and p=0.650 for TSS and DFS, respectively). This result was verified by Kaplan-Meier survival analyses after propensity score matching (p=0.234 and p=0.765 for TSS and DFS, respectively). @*Conclusion@#LVSI does not significantly compromise the survival outcome of Chinese EEC patients.
RESUMO
Objective To study the surgery effect on early application of toe flap to repair thumb severe electric bum.Methods From July 2007 to October 2017,a total of 25 cases of thumb severe electric burn were repaired by thumb toe flap grafting.The function of the finger after operation was evaluated comprehensively,and the effect of 72 hours before and after the injury was compared.Results All the flaps survived and the finger function was excellent.The excellent and good rate of 25 cases was 72％.The excellent and good rate of 72 hours before and after injury were 85.7％ and 54.5％ respectively.5 cases had bad wound complications after operation.1 cases were operated within 72 hours after injury,and 4 cases were operated after 72 hours.Conclusions The early application of toe flap to repair severe electric bum thumb can maximize the recovery of function of the thumb.The earlier the operation,the fewer complications,the better the repair effect.
RESUMO
Objective To investigate the difference of vacuum sealing drainage (VSD) on the effect of one-stage skin graft and second-stage sugery after scar release.Methods A total of 42 patients who wanted to undergo scar release and skin graft was randomly divided to control group (n =21) and VSD treatment group (n =21).The control group implemented skin graft immdiately after scar release while VSD treatment group were treated with VSD for 3 days after scar release and then implemented skin graft.The rate of subcutaneous blood stasis and the survival rate of skin graft were observed at 7 days after skin graft.The condition of grafted skin contracture and hyperplasia after half a year was also observed.Results The incidcnce of subcutaneous blood stasis was significantly lower in the VSD group than that in the control group (P ＜ 0.05).The survival rate of skin grafts was significantly higher in the VSD group than that of the control group (P ＜ 0.05).The score of Vancouver scar was significantly lower in the VSD group than that in the control group (P ＜ 0.05).Conclusions VSD treatment of second-stage sugery after scar release can reduce the occurrence of subcutaneous blood stasis,promotc skin graft survival,reduce postoperative skin graft contracture and improve the prognosis of patients compared to one-stage skin graft.
