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.

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.

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.

A sensitive, rapid and specific liquid chromatographic-tandem mass spectrometric (LC-MS/MS) method for quantification of gabapentin in human plasma has been developed. After a single plasma protein precipitation with methanol, gabapentin and metformin (internal standard) were chromatographed on a Inertsil ODS-3 column (50 mm x 2.1 mm ID, 3 microm) with mobile phase consisting of methanol-0.2% formic acid aqueous solution (80:20, v/v) at a flow-rate of 0.2 mL x min(-1). Electrospray ionization (ESI) source was applied and operated in the positive ion mode. Multiple reaction monitoring (MRM) mode with the transitions of m/z 172 --> m/z 154 and m/z 130 --> m/z 71 were used to quantify gabapentin and metformin, respectively. The run time was 2.2 min. The linear calibration curve was obtained in the concentration range of 40.8-8.16x10(3) ng x mL(-1). The lower limit of quantification was 40.8 ng x mL(-1). The intra- and inter-day precision (RSD) was less than 12%, and the accuracy (RE) was within +/-6.4% calculated from quality control (QC) samples. The method was used to determine the concentration of gabapentin in human plasma after a single oral administration of 600 mg gabapentin capsule to 20 healthy male Chinese volunteers. The method was proved to be selective, sensitive, rapid and suitable for pharmacokinetic study of gabapentin in human plasma.

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.

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.
