As a new concept, the definition of translational medicine remains obscure. The translational medicine connects the bench to bedside, and its importance would be more remarkable. The development of gastrointestinal surgery reflects the idea of translational medicine. To carry out the translational study, the gastrointestinal surgeon must learn how to find subjects from clinical problems, how to collect complete information and tissues, how to collect complete information and tissues, how to collaborate with others from different fields and how to utilize all kinds of resources. By translational studies, gastrointestinal surgeons may further improve the survival of patients with gastrointestinal tumor.

Robotic system helps surgeons in performing surgery. Currently Da Vinci system is the most popular. Da Vinci system has been used for the stomach and bowel diseases in 27 cases(18 cases of stomach and 9 cases of colon and rectum) in the Zhongshan Hospital, Fudan University. Accurate preoperative staging is crucial, and Da Vinci system is advantageous in lymph node dissection, preservation of nerve plexus, and complete resection of mesorectum. Adoption of gastrointestinal tract reconstruction technique should depend on the operation and experience in surgery. Though Da Vinci system has limitations and the cost is high, it is believed to be the future trend.

Background and purpose: The prognosis of completely resected stage ⅢA(N2) non-small cell lung cancer (NSCLC) remains a significant concern. The 5-year overall survival (OS) rates range from 10% to 30%. This study aimed to analyze the patterns of first failure in completely resected stage ⅢA(N2) NSCLC and to assess the actuarial risk of developing metastasis at different sites and to guild standard clinical practice. Methods: Patients withⅢA(N2) NSCLC who had undergone radical surgery in our hospital from Jan. 2005 to Jul. 2012 were retrospectively reviewed. The progression-free survival (PFS), the OS, patterns of first failure, the actuarial risk were analyzed. The cumulative incidence of first failure was determined using the Kaplan-Meier analysis. Results: Among 357 patients who met the eligibility criteria with completely resected stage ⅢA(N2) NSCLC, 5-year OS was 36.9%. There were 284 (77.6%) patients experiencing disease failure: 61 with local failure, 197 with local and distant failures, and 26 patients with local recurrence as the first failure. Brain, bone and lung were the main sites of distant failure as the first failure, while brain was the most common site. There were 67 patients developing brain metastases (BM) as the first site of failure. The median time of local failure as the first site of failure was 13.6 months, and the time to develop distant recurrence was 15.1 months. 92.5% BM developed in 3 years after the complete resection. Conclusion: As the first failure, the rate of distant failure was much higher than that of local failure in completely resected stage ⅢA(N2) NSCLC. Brain was the most common site of distant failure as the first failure. These results can be helpful in guiding standard clinical practice and evaluating the outcome of comprehensive treatment.

Objective To explore the value of Ligasure vessel sealing system(LVSS)during resection of retroperitoneal tumor.Methods Group 1 including 32 cases were performed resection of retroperitoneal tumor with LVSS and electrosurgical seapel from Jun.2004 to Oct.2008.group 2 including 26 cases were done with electrosurgieal seapel from Jan.2001 to Jun.2004.Operating blood loss,operating time,iatrogenic injury,postoperative blood loss and hospital stay were compared between the two groups.Results There was no significant difference in hospital stay[(11.7±0.7)d vs.(12.3±1.4)d)]and iatrogenic injury(9.38%vs.16.00%)between two groups statistically(P＞0.05),but the intraoperative blood lose[(403.1±37.1)ml vs.(704.0±129.0)m1)s,postoperative blood loss[(131.5±18.4)ml vs.(214.8±29.2)ml)]and operating time[(166.5±8.9)min vs.(186.8±15.4)min]were less in group 1 than that in group 2(P＜0.05).Conclusion Ligasure vessel sealing system has advantages of safe coagulation,shortening operation time in resection of retroperitoneal tumor.

Objective Implementing the scientific research performance evaluation indicator system constructed to evaluate the situation of scientific research performance conducted by two basic Departments during the 12th Five-Year period in a general hospital.To understand the practical applicability of the scientific evaluation index system,and also propose comments and suggestions based on the comparison between assessment score and actual research situation in the departments.Methods Based on the database of scientific research management information platform,collect related research data from two basic departments of the hospital in latest five years.Using SPSS software to conduct statistical analysis on the total score of the first and two indicators,as well as the specific indicators of the three indicators,according to the performance evaluation index system and the weight built by the hospital.Results The index system can basically reflect the general information of scientific research input and output in the department,however,some indicators cannot truly reflect the index importance and the differences between the index weight is not significant,so it is necessary to make amendment based on demonstration.Conclusions Hospital should dynamically update the index system to make them match the developing strategy of the hospital,also important to combine them with research stimulation to guarantee more scientific management and better service to the research development of hospitals.

Objectives:To understand the current situation of premenstrual syndrome (PMS) and type D personality in female college students,and to explore the relationship between them.Methods:Totally 856 female college students were assessed with the Premenstrual Syndrome Scale (PMSS,those with total score of 6 or higher as having PMS) and Type D Personality Scale 14 (DS-14,those negative emotion and social inhibition factor with total score of 10 or higher as having type D personality).Result:A total of 280 students were detected with PMS,and the rote was 32.7％.Totally 272 students were detected with the type D personality,and the rote was 31.8％.The total score of DS-14 and the score of 2 factors were higher in PMS group than in non-PMS group (Ps ＜0.001).The rate of PMS was lower in type D personality group than in non-type D personality group (11.76％ vs.25.34％,P ＜ 0.001).Conclusions:The occurrence of premenstrual syndrome may be related to the type D personality.The evaluation of personality characteristics should be taken into consideration when formulating the intervention program.

Objective To observe the serum cardiac troponin I (cTnI) level and to analysis the relations between the serum cTnI level and prognosis in patients with dilated cardiomyopathy (DCM) and Cardiac Dysfunction.Methods Serum cardiac cTnI level was measured by enzyme-linked immunosorbant assay. Results The serum cTnI level in DCM patients with class IV cardiac function (0.53 ?0.31) ?g/L was significantly higher than in DCM patients with class Ⅲ cardiac function (0.45?0.27) ?g/L.There was significantly difference in serum cTnI levels between DCM patients with class Ⅲ cardiac function and DCM patients with class Ⅱ cardiac function(0.29?0.27) ?g/L.Conclusion The higher serum cTnI level is correlated with the severity of cardiac function and may be useful for evaluating prognosis in patients with DCM.

Objective To investigate whether arsenic trioxide(As2O3)with different density is capable of affecting the invasiveness of neuroblastoma(NB)cells,and to give grounds for NB therapy with As2O3.Methods 1.Well-developed NB cells were selected and exposed to 0.75 ?mol/L,1.50 ?mol/L,3.0 ?mol/L As2O3 for 24 h;2.Collect the adherence cells,count the number and float them in nutrient medium again,add them into the transwell polycarbonate membrane plate that was covered by matrigel,there were 2?104 NB cells in each well;3.After 24 h,take off the membrane,fix the cells which cross the membrane with mehanol and dye them with hematoxylin;4.Observe the NB cells and count them,so the capability of invasion of LA-N-5 was evaluated by transwell chamber assay.Results After 24 h with the different density As2O3,the number of invading LA-N-5 cells was significantly lower in As2O3 group than that in control group(the number of invading cells of the As2O3 group was 28.0?4.0,19.33?4.16,6.33?1.53,respectively,the cell number of the control group was 46.33?6.11)(P=0.013,0.003,0);among the experiment groups,there was no difference between 0.75 ?mol/L and 1.50 ?mol/L(P=0.06),and it was significantly different between 0.75 ?mol/L and 3.0 ?mol/L,1.50 ?mol/L and 3.0 ?mol/L(P=0,0.007),the number of invading LA-N-5 cells of 3.0 ?mol/L As2O3 was the least.Conclusions As2O3 could inhibit the invasive potential of NB cells;the inhibitory action of 3.0 ?mol/L As2O3 is the most.
