Objective To observe the application and the curative effects of vacuum sealing drainage (VSD) in the treatment of skin injury of trauma surgery .Methods The 50 cases with severe traumatic skin injury treated with VSD were compared with tra-ditional dressing group(control group 50 cases) to observe the curative effect of the two groups .Results Compared with control group ,VSD group improved the success rate of follow-up skin graft .Good skin graft in VSD group were obvious more than the con-trol group(P<0 .01) .Conclusion The VSD can improve the success rate of skin graft ,accelerate wound healing .At the same time , VSD can avoid the pain due to reducing the times of changing dressings .It is a good method of treating severe traumatic skin injury .

Objective To analyze the clinical effect of vacuum sealing drainage (VSD) on skin and soft tissue injury in elderly patients.Methods A total of 75 patients with severe skin and soft tissue injury who met the inclusion criteria were enrolled in this study.They were divided into two groups based on admission dates:the observation group (n =40,receiving VSD treatment,oddnumber date admission) and the control group (n=35,receiving routine dressing changes,even number date admission).The clinical indexes including pain score,wound healing time,infection rate and complications were analyzed and compared between the two groups.Results There was a significant difference in the average length of hospitalization between the two groups (21.3 days vl 30.7 days,t=7.60,P=0.0000).The infection rate was lower in the observation group than in the control group (12.5％ or 5/40 vs.54.3％ or 19/35,x2=13.12,P=0.0003).The incidence of complications was lower in the observation group than in the control group (15.0％ or 6/40 vs.42.9％ or 15/35,x2=5.87,P=0.0154).There were no deaths in the observation group,but one patient died from acute pulmonary embolism in the control group during hospitalization.Conclusions VSD can alleviate pain,reduce the infection rate,shorten the length of hospitalization and decrease bedridden complications in elderly patients with severe skin and soft tissue injury,and has valuable applications in clinical practice.

Objective To investigate the effect and mechanism of tripterygium wilfordii combined with aescine in treatment of acute lung injury (ALI) following trauma.Methods A total of 120 patients with posttraumatic ALI were divided into four groups:tripterygium wilfordii + aescine group (combined group),tripterygium wilfordii group,aescine group,and control group according to random number table,with 30 patients per group.Regardless of the same conventional therapy,the patients in combined group were treated by orally or gastrically administered tripterygium wilfordii multiglycoside as well as aescine intravenously,once a day for 12 days; on the contrary,the same method but only with tripterygium wilfordii or aescine was respectively performed in tripterygium wilfordii and aescine groups.Blood gas analysis before and after treatment,length of ICU stay,fatality rate and incidence of ARDS in each group were observed.Changes in levels of inflammatory mediators (TNF-oα,IL-1,IL-6 IL-8,etc)were detected at days 4,8,and 12 after medication.Results Shorter length of ICU stay and lower ARDS incidence as well as 12-day fatality rate were detected in each treatment group as compared with control group,especially in combined group (P ＜ 0.05).Respiratory rate,PaO2 and oxygenation index (PaO2/FiO2) in each treatment group presented better amelioration than those in control group and especially better results were observed in combined group (P ＜ 0.05).Plasma levels of TNF-α,IL-1,IL-6,and IL-8 in each treatment group were lower than those in control group (P ＜ 0.05).Conclusions Tripterygium wilfordii and aescine havetherapeutic effect on posttraumatic ALI.Moreover,synergetic use of the two drugs achieves synergistic effect and better outcome.

Objective To observe the efficacy and side effects of exemestane in postmenopausal breast cancer patients with bone metastasis.Methods One hundred and ten postmenopausal breast cancer patients with bone metastasis were treated with exemestane 25 mg.Results In the evaluable data from 110 patients,the complete remission(CR)was encountered in 7 cases,partial remission(PR)in 28 cases,with a total response rate of 31.8％ ;Thirty nine patients had stabled diseases for more than 24 weeks.It produced a clinical benefit (CR + PR + SD)over 24 weeks in 74 cases(67.3％).Diseases progressed in 12 of the cases(10.9％).The patients with positive ER and PR status had a higher chance to be benefited from the treatment than those with negative receptor status.The clinical efficacy was not correlated with treatment history,pathological subtypes and bone,liver,lung and lymph node metastasis(x2 =0.045,0.078,0.200,P ＞ 0.05).No severe adverse effects were observed.Conclusion Exemestane is effective to treat bone metastasis of breast cancer with minor adverse reactions and good tolerability.

Objective To study the early diagnosis,surgical treatment options,prevention and management of complications in patients with duodenal trauma.Methods All patients with duodenal trauma treated operatively from January 2009 to December 2018 were studied retrospectively.Factors including sex,age,cause of injury,AAST grading,diagnostic method,operative procedure,therapeutic effectiveness,complications,and factors related to death were analyzed.The "double-tube gastrostomy" technique consisting of duodenal decompression and jejunal feeding as recommend by the authors were used in severe cases.Results Blunt trauma occurred in 66 of 86 patients (76.7％).The diagnosis of duodenal trauma was made preoperatively based on abdominal signs,peritoneocentesis,and imaging in 32 patients (37.2％).The remaining 54 patients (62.8％),with duodenal injury was detected during emergency laparotomy.All the 86 patients underwent surgical intervention which included simple suturing,pedicled jejunal flap,segmental resection and anastomosis,Roux-en-Y duodenojejunostomy,diverticularization,and Whipple's procedure using the principle of Damage Control Surgery (DCS).Postoperative morbidity occurred in 15 patients (17.4％).There was a high incidence of duodenal (or pancreatic,biliary) fistulae.The overall mortality rate was 12.8％ (in 11 patients).The causes of deaths were mainly massive bleeding and poly-trauma.Conclusions To decrease morbidity and mortality rates,early diagnosis and surgical intervention were critical.The choice of surgical treatment procedures should be based on the duodenal trauma grading and whether there were associated injuries.For patients with a combined pancreaticoduodenal trauma,DCS is a wise procedure to adopt.The double-tube gastrostomy technique as recommended by the authors is beneficial to severe cases in decreasing the incidences of postoperative duodenal and jejunal obstruction.
