Objective To compare the effect of silver-coated dressing and general aseptic dressing on the wound healing of abdominal operation. Methods A total of 94 patients from the general surgery department of Second Affiliated Hospital of Xi'an Jiaotong University who underwent abdominal operation were divided into two groups by double blind method, 49 cases in silver-coated dressing group, and 45 cases in general aseptic dressing group. The wound healing of the two groups were observed after wound dressing change, and the wound dressing change times, the healing time, the degree of pain, the positive rate of bacterial culture and the incidence rate of scar healing were observed in the two groups. Results The patients in silver-coated dressing and general aseptic dressing group had no significant differences in gender, age, length of incision, type of incision and poor wound healing type (all P>0.05);after two wound dressings change treatment, the wound dressing change times and incision healing timeof the silver-coated dressing group was (6.52 ± 1.52) times and (16.34 ± 5.96) days, which were less than those of the general aseptic dressing group, which were (8.74 ± 2.35) times and (23.32 ± 8.32) days; and the pain severity (NRS) scored 4.13 ± 1.01, which was lower than that of general aseptic dressing group (6.54 ± 0.95), with significant difference between two groups (t=5.482, 4.704, 11.890, P < 0.05). The bacterial culture positive rates of the silver-coated dressing group was 60.00% (21/35), which was higher than that of the general aseptic dressing group, 23.33%(7/30), the difference was statistically significant (P<0.01);at the same time, the scar healing cases was 4 in the silver-coated dressing group, which was less than 11 cases in the general aseptic dressing group. The difference was statistically significant (P < 0.05). Conclusions The silver-coated wound dressing method is better than the general aseptic wound dressing, and has obvious advantages in the treatment of abdominal poor healing incision. The silver-coated wound dressing can promote the healing of incision, reduce scar healing, shorten the hospitalization time, reduce the suffering of patients.

Objective To evaluate retrograde transpopliteal access for femoral-popliteal artery total occlusion with blind puncture.Methods Clinical data of 22 cases admitted from Sep 2014 to June 2016 undergoing endovascular treatment of the femoral-politeal artery occlusion with transpopliteal artery retrograde access by blind puncture were analyzed.Results A total of 22 patients underwent retrograde popliteal access with blind puncture after antegrade attempts failed.Puncture above the knee was performed in 18 cases and below the knee in 4 cases.The average increase of ABI was 0.57.Hematoma of puncture site was observed in 2 patients,other complications included pneumonia in 1 case and renal insufficiency in 2 cases.The mean follow-up time was (13 ± 5)months.Restenosis occurred in 8 patiens(36.4%)during the follow-up time.The primary patency was (86.4 ± 0.07) % at 6 months and (70.7-± 0.12) % at 12 months.There was no major amputation rate and mortality during the follow-up.Conclusions Retrograde transpopliteal access for femoral-popliteal artery occlusion with blind puncture is safe and effective.

Objective To investigate the effect of time interval between diagnosis and surgical treatment on the prognosis of breast cancer.Methods A retrospective study that include a total of 252 female patients who underwent breast cancer diagnosis and treatment in the Second Affiliated Hospital of Xi'an Jiaotong University from April 2012 to August 2014 were included in the present study,the average age was (58.2 ± 10.8) years old,range from 31 to 67 years old.General demographic information and data of tumor were collected.Information on postoperative recurrence,metastasis,death,and disease-free survival status of breast cancer patients were followed up 5 years by outpatient follow-up or telephone follow-up.All participants were divided into four groups (<2 weeks,2-4 weeks,4-8 weeks,≥8 weeks) by the time interval between diagnosis and surgical treatment,including 26,118,78 and 30 cases,respectively.In addition,according to the diameter of breast cancer tumors,all participants were divided into three groups (<20 mm,20-40 mm,and ≥40 mm),including 99,124,and 29 cases,respectively.According to the results of pathological examination of the lymph nodes obtained during intraoperative dissection,the all participants were divided into three groups (lymph nodes without metastasis,1 to 3 metastasis,and ≥3 metastasis),including 66,124,and 62 cases,respectively.The Cox proportional regression risk models were used to assess the hazard ratio (HR) and its 95% confidence interval (CI) of time interval between diagnosis and surgical treatment with the prognosis of breast cancer,with adjustment for age,education levels and body mass index.Further,stratified analysis by tumor characteristics,including pathological type,histological grade,tumor diameter,lymph node metastasis,and receptor expression were also conducted to evaluated the above association.Kaplan-Meier survival curve was used to evaluate the effects of time interval between diagnosis and surgical treatment on the prognosis of breast cancer.Results The Kaplan-Meier survival curves for the five-year follow-up of total survival time between 4 different time intervals groups showed significantly different (P <0.001),and patients with a pre-treatment interval of <2 weeks had the longest survival time,while those with ≥8 weeks had the lowest survival time.With a one-week interval before treatment,the overall risk of death in breast cancer patients increased by 6% (HR =1.06,95% CI:1.01-1.1 l),and the risk of breast cancer death increased by 8% (HR =1.08,95% CI:1.02-1.14),the risk of distant metastasis of breast cancer cells increased by 10% (HR =1.10,95% CI:1.08-1.13).With the increase in breast cancer tumor diameter (<20 mm,20-40 mm,≥40 mm),the overall risk of death due to prolonged treatment interval increased gradually,with HR (95%CI) were 1.06 (1.03-1.09),1.08 (1.02-1.12) and 1.11 (1.05-1.17),respectively.With the increase of lymph node metastasis in breast cancer (no metastasis,metastasis at 1-3,≥ 3 metastasis),the total mortality risk caused by prolonged treatment time interval also showed an increasing trend,with HR (95%CI) were 1.04 (1.02-1.08),1.06 (1.04-1.08) and 1.08 (0.99-1.11),respectively.The same results were also shown in the effect of tumor diameter or distant lymph node metastasis on the association between treatment time interval and breast cancer survival and distant metastasis of breast cancer cells.Conclusion With the prolongation of the time interval between the diagnosis of the breast cancer and the surgical treatment of breast cancer patients,the risk of postoperative death is significantly increased,and the association is more pronounced in breast cancer patients with larger tumor volume or higher distant lymph node metastasis.
