The technique of Radiofrequency ablation (RFA) has been widely applied as alternative treatment for non resectable hepatocellular carcinoma (HCC) and has equivalent efficacy in prognosis.However,because of the restriction of current heat ablation technique and tumor's special location in liver,it is difficult for some physicians to obtain the ideal of one-off complete ablation.Therefore,incomplete destruction of tumor and multiple ablation processes resulted in miserable consequence in prognosis.So,to achieve one-off complete ablation,it is essential to evaluate the anatomy location of the tumor before RFA procedure and to establish the specified approach and adjuvant method.This article is to systematically analyze the theoretical hypothesis of this technique and to explore possible strategy for a safe approach based on characteristics of liver anatomy and combined with the professional advantages of hepatobiliary surgery.

Integron was a novel bacterial resistance gene horizontal transmission element.In recent years, many researchers made a lot of research on the resistance mechanism of pathogen.In this paper, the detection and the novel discovery of the integron gene cassette were summarized , including Enterobacteria, Acinetobacter baumanii, Pseudomonas aeruginosa and other bacteria , on the basis of the multidrug resistance mechanism mediated by integron.The prospect the research was descixbed and more attention should be paid to the prevention and control of multidrug resistant bacteria.

Bilioenterostomy with a wide variety of techniques is a common surgical operation in digestive surgery.Each of these surgeries has its own advantages and disadvantages.At present,Roux-en-Y choledochojejunostomy seems to be the dominant surgery,while other operations are used in some particular circumstances.Furthermore,some modified surgeries for bilioenterostomy have been conducted with the deepening understanding of the complications.Additionally,different kinds of new facilities and techniques have been applied to bilioenterostomy.Despite the controversy on specific issues,reasonable choice of bilioenterostomy should follow thc principles of specific purpose,correct choice and reliable effect.In other words,whether or not using bilioenterostomy should be considered correctly from the whole system,and then surgical methods should be accurately chose for patients,and finally avoiding the technical errors and guaranteeing the surgical effects.

Objective Using stem tip of Gymnadenia conopsea in this experiment to investigate somatic embryogenesis and plant regeneration in vitro.Methods Uniform dedign for the most suitable media for embryogenic callus induction and embryogenic cell complex,development of somatic embryo and plant regeneration were screened.Results The results showed that Chaturvedi and Mitra(CM)+6-BA 1.0 mg/L+IAA 2.0 mg/L+2,4-D 0.1 mg/L was fit for embryogenic callus and embryogenic cell complex induction.Percentage was 98%;The medium of development of somatic embryo and plant regeneration was CM+6-BA 1.00 mg/L+IAA 0.10 mg/L.Percentage was 100% and converted into plantlets with shoots and roots after 50 d culture on the same medium.Conclusion The observation of morphostructure and ultrastructure proves the process of somatic embryogenesis of G.conopsea.

Objective To summarize and evaluate the technique and clinical outcome of limited tarsal sinus incision plus locking plate internal fixation for minimally invasive treatment of intra-articular calcaneal fractures. Methods Between February 2010 and February 2011,16 cases of intra-articular calcaneal fractures were treated in a minimally invasive manner in our department. All cases were evaluated carefully with routine X-rays and CT scans preoperatively to define the type of fracture and the involvement of articular surface.Open reduction and locking plate internal fixation with percutaneous screws were performed via a limited tarsal sinus approach 3 to 6 days after injury (average,4 days).Regular X-ray follow-ups were conducted to measure the Bohler's and Gissane angles.Overall functional evaluation was carried out according to Visual Analogue Scale (VAS),the Hind-foot Score by American Orthopaedic Foot and Ankle Society (AOFAS) and Short Form 36 Health Survey Questionnaire (SF-36).Complications were recorded as well.Results The 13 cases were followed up for a mean duration of 18 months (from 12 to 24 months).There were no wound infection,skin and flap necrosis or implant failure.Bone union was achieved at an average of 10 weeks (from 8 to 12 weeks) post-operatively.The average Bohler's angle was improved significantly from 13.4° ± 3.4° (from 8° to 19°) pre-operatively to 26.5° ± 4.5° ( from 21° to 38°) post-operatively ( t =9.781,P ＜ 0.001 ).The average Gissane angle was improved significantly from 88.1° ± 7.6° (from 77° to 100°)pre-operatively to 116.2°±7.5° (from 100°to 124°) post-operatively (t =12.934,P ＜0.001).On average,the VAS score was 1.5 ± 1.7,the AOFAS score was 84.2 ± 5.9 and the SF-36 score was 79.5 ± 8.1 at the final follow-up.The follow-ups revealed no post-traumatic arthritis. Conclusion Open reduction and locking plate fixation with percutaneous screws via a limited tarsal sinus incision is a safe and reliable treatment for intra-articular calcaneal fractures,because it has the advantages of direct reduction of the articular surface,solid fixation,and limited soft tissue complications.

Objective To compare the lymph node dissection of left chest single incision and neck-right chest-abdomen incision in esophageal cancer surgery,and to explore the reasonable range of lymph node dissection in esophageal cancer surgery.Methods We retrospectively analyzed the clinical data of 72 patients with esophageal cancer radical surgery.According to the surgical approach,the patients were divided into left chest single-incision group (32 cases) and three-incision group (40 cases).The surgery time,number of lymph node resected,drainage tube time,length of hospital stay,lymph node dissection status and incidence of postoperative complications were analyzed.Results In left chest single-incision group and three-incision group,the operative time [(225.44 ± 11.98) min vs (265.42 + 13.15) min],lymph node dissection number[(8.031 ± 1.153) vs (11.821 ± 1.138)],length of stay [(13.212 ± 1.294) d vs(15.691 ± 1.404) d] and other aspects had statistically significant differences (t =24.201,25.302,14.010,all P ＜ 0.05).There were no significant differences between two groups in the chest tube indwelling time and the incidence of postoperative complications (P ＞ 0.05).Conclusion Both surgical radical resection of esophageal cancer have their own characteristics in terms of surgical difficulty,risks,efficacy and complications.In clinical,these must be carefully evaluated in patients with lesions and body affordability flexibility to choose the surgical approach in order to achieve the best therapeutic effect.
