Objective:To investigate the effects of laparoscopy assisted complete mesocolon resection on the stress response and immune function of patients with colon cancer.Methods:From January 2013 to January 2016,130 patients with colon cancer in our hospital were selected and randomly divided into the observation group and the control group with 65 cases in each group according to the random lottery envelopes.The observation group was treated with laparoscopy assisted complete mesocolon resection,the control group was treated with open operation.The changes of semm IL-6,TNF-α and amours of CD4+ cells,blood loss,bowel function restoration time,hospital stays and complication rate of two groups were compared before and after treatment.Results:Both groups of patients were successfully completed the surgery and there was no serious complications occurred in both groups.The amount of bleeding,postoperative intestinal recovery time and postoperative hospital stay in the observation group were significantly less than those of the control group (P＜0.05).The chylous fistula,wound infection,pulmonary infection and complication rate on the 14th day postoperation in the observation group was 1.5％,which was 12.3％ in the control group and significantly higher than that of the control group (P＜0.05).The contents ofCD4+ cells in the observation group and the control group were 36.34± 7.83％ and 33.66± 9.82％,respectively,which were significantly higher than those before treatment(30.33± 6.49％ and 30.49± 5.33％)(P＜0.05),and the contents of CD4+ cells of observation group was significantly higher than that of the control group after treatment (P＜0.05).The serum levels ofIL-6 and TNF-α in both groups were significantly lower than those before treatment on the 14th day postoperation (P＜0.05),and the serum IL-6 and TNF-α levels of observation group were significantly lower than those in the control group on the 14th day postoperation (P＜0.05).Conclusion:Laparoscopy assisted complete mesocolon resection could promote the immune function and inhibit the stress response,which further promoted the rehabilitation and induced the complications in the treatment of patients with colon cancer.

OBJECTIVE To study the carbapenemase genotypes among Acinetobacter calcoaceticus isolates infected after liver transplantation. METHODS The 5.4 software was used to analyze the resistance of Acinetobacter species. Eight strains of imipenem-resistant A. calcoaceticus which were resistant to multiple drugs were collected. Analytical isoelectric focusing electrophoresis was used to measure the pI of the ?-lactamase. The homology of the isolates was determined by pulsed field gel electrophoresis(PFGE). blaTEM, blaSHV, blaIMP, blaVIM, blaOXA Genes for resistant isolates were amplified and sequenced. RESULTS Imipenem-resistant A. calcoaceticus infected after liver transplantation was resistant to multiple drugs. All of 8 strains were produced OXA-23 carbapenemases (pI of 6.7). The results of PFGE indicated there was a trend of resistant clone transmisstion in the transplantation ward. CONCLUSIONS There is a transmisstion of A. calcoaceticus producing OXA-23 carbapenemase in the transplantation ward of our hospital. It is important to monitor powerfully the bacterial resistance to control infection more effectively.

Objective To investigate the survival benefit of patients with esophageal squamous cell carcinomas who recieved postoperative chemotherapy of tegafur combined with FT-207 radiotherapy.Methods Data from 126 patients with esophageal squamous were analyzed who undergone radical resection from January 2008 to December 2010,consisting of 92 patients underwent surgery alone and 34 patients took oxaliplatin combined with tegafur postoperatively (oxaliplatin 130 g/m2,d1,tegafur 500 mg/m2,d1-5,21 d for a cycle,every patient received at least two cycles).Results The 1-year survival rate and 3-year survival rate was 93.5 ％ and 75.0 ％ in the surgery alone group,was 97.1％ and 76.2 ％ in the surgery plus postoperative chemotherapy (P =0.590).There was no significant differences in survival in the two groups,even with Coxregression multivariate analysis and with stratifications of gender,age,tumor location,degree of cell differentiation,invasion depth,lymphatic metastasis and TNM stage.Conclusion Postoperative adjuvant chemotherapy with oxaliplatin combined with tegafur has not significantly improve the survival rate of patients with esophageal squamous cell carcinomas undergoing radical resection.It is still lack of an effective project for postoperative adjuvant chemotherapy for esophageal cancer,and it is necessary for further study.
