Quality is the lifeline of graduate education and the tutor team plays an important role in postgraduate training. To control the selection of tutors strictly, to implement the combination of openness and stability in tutor team, and to carry out academic exchanges actively are the keys to construct an excellent tutors staff and to ensure the quality of graduate student training.

Objective To assess the diagnostic value of Manning's criteria, Rome Ⅰ criteria and Rome Ⅱ criteria in Chinese patients of irritable bowel syndrome. Methods 724 subjects were enrolled from the outpatient department of gastroenterology and the physical examination center of Xinhua hospital. Self designed questionnaire, routine physical examination and selective accessory diagnostic procedures were undergone in all subjects including 402 cases of irritable bowel syndrome,134 cases of non ulcer dyspepsia,90 cases of ulcerative colitis and 98 healthy controls. According to Manning criteria, Rome Ⅰcriteria and Rome Ⅱcriteria, the sensitivity, specificity, positive likelihood and negative predictive value(PV), positive likelihood and negative likelihood were calculated separately. Results The sensitivity and specificity of Manning's criteria, Rome Ⅰ criteria and Rome Ⅱcriteria were 96.02% (95%CI:95.06%-100.0%), 77.36% (75.31%-79.41%), 68.41% (66.14%-70.68%) and 47.51% (44.78%-50.23%), 73.29%(70.87%- 75.70 %) 83.23% (81.19%-85.27%),respectively. The positive PV and negative PV were 69.55%, 78.33% , 83.59% and 90.53%, 72.17%, 67.85%, respectively.The positive likelihood and negative likelihood were 1.83 , 2.90 , 4.07 and 0.08, 0.31, 0.38, respectively. Conclusion Irritable bowel syndrome could be positively diagnosed by taking an appropriate history and questionnaires,Rome Ⅱ criteria had higher validity in diagnosis of irritable bowel syndrome.

Cationic lipid nanoparticles possessing favorable biocompatibility and controllable particle size has at-tracted increasing attention in the field of non-viral vectors for delivering nucleic acids in vitro and in vivo.1,2-Dilinoleyloxy-3-dimethylaminopropane(DLinDMA)and its derivatives,one of the most important cationic lipid materials,have been widely studied as the mainly composition of cationic lipid nanoparticels.This paper summa-rized the structure,characteristics and clinical application of DLinDMA nanoparticles.

The medical students, Shanghai Jiaotong University School of medical from 5- year,7-year, 8-year to general of academic, received evidence-based medicine (EBM) education. The students' background and attitudes about EBM were different. Teaching EBM should pay attention to the relationship of EBM and basic courses, especially for deferent students. Teaching EBM should transform from imparting basic knowledge to learning skills on their own initiative.

Objective To develop a Scoring System for Academic Conference Papers,in order to achieve real-time paper scoring in large academic conference with the information technology and network.Methods Based on Microsoft.Net technology,an information system Was developed,supporting multimeeting.multi-client and dynamic screen show.Results In this system,the conference inforrnation,meeting name and scoring standards Call be customized;the doctor information,papers information,used time,score detail and dynamic list Can be displayed in the screen.This system has been applied in national ophthalmic conferences several times and gained praise from the organizing committee and judges.Conclusions The scoring system for Academic Conference Papers can significantly improve efficiency,help to promote the standardization of paper scoring,and manifest the open,fair and just principles.It is worth of spreading.

OBJECTIVE:To screen formulation of Insulin cream and to investigate the effects of insulin cream on wound healing in rabbits.METHODS:The best formulation of insulin cream was selected from 8 kinds of formulations with appearance and stability as index.Rabbit trauma model were induced and divided into matrix group,blank group,Insulin cream groups(high-dose,medium-dose and low-dose).Wound healing rate and healing time were compared among those groups.RESULTS:The fifth formulation possessed good appearance and stability,which included albolene,cetanol,glycerin monostearate,glycerol,etc.Compared with matrix group,the wound healing rates were obviously increased at different time points in Insulin cream groups(P

This paper points out the experimental animal ethics education in pharmacology teaching and the im-portance of the experiment,it is good to raises the student good humanity accomplishment and scientific research quality, and promote medical research and life ethics of benign interaction.It also expounds the basic content of ex-perimental animal ethics education,including:animal welfare, the 3R principle, AAALAC accreditation and analy-sis of the experimental animal welfare legislation status, raises questions about animal ethics education problems and thinking in the pharmacology experiment teaching in ourschool.The experimental animal ethics education should become an important part of pharmacology experimental teaching, which enhanced the students′s ethical awareness to better understand and respect for life, and contribute to the sustainable development of medical and pharmaceutical research.

Objective To discuss and analyze the imaging features of extramedullary hematopoiesis (EMH).Methods Imaging data of EMH in 7 patients with 85 lesions confirmed by clinical and pathological results were retrospectively analyzed.Results CT or MRI showed thoracic paravertebral multiple tumor-like soft tissue masses in 6 patients accompanied with pleural mass in 1,with liv-er mass in 1 and spleen mass in 1,and the masses in the distal ileum and in front of the inferior vena cava in 1.Thoracic paraverte-bral and pleural masses presented isodensity on plain CT and moderate enhancement on post-contrast CT.Among the 6 liver mas-ses,CT showed uniform density in 5 and small area of necrosis in 1.The only one spleen mass also appeared inner necrosis and mul-tiple small calcifications.The mass in the ileum presented thickened bowel wall with moderate enhancement,meanwhile the mass in front of vena cava presented obvious edge enhancement.MRI in 2 patients showed the masses with low signal on T1 WI and high sig-nal on T2 WI.Conclusion EMH has certain specific imaging characteristics,which may be helpful for correct diagnosis of EMH when combined with the clinical data.

Objective To study the association between activity of hand,foot and mouth disease (HFMD) and the meteorological factors in Suzhou.Methods A total of 17 653 children diagnosed with HFMD in Children's Hospital Affiliated to Suzhou University during 2008 to 2011 were enrolled.The meteorological factors in(c)luding mean temperature,relative humidity,rainfall amount,sum of sunshine and mean wind velocity during Jan 2008 to Dec 2011 were collected monthly.Numeration data were analyzed using chi square or Fisher exact test.Normal distribution data were analyzed using Pearson correlation and non-normal distribution data were analyzed using Spearman rank correlation.Results HFMD could be found all over the year and had obvious seasonality which peaked in Summer,followed by Spring and Autumn and HFMD decreased markedly in Winter.The activity of HFMD was positive correlated with mean temperature(r=0.716,P＜0.01),wind velocity (r=0.630,P＜0.01),rainfall(r=0.477,P＜0.01) and sum of sunshine(r=0.311,P＜0.05).No statistical significance was observed between relative humidity and HFMD(r =0.276,P＞0.05).Multivariate stepwise regression analysis showed that only mean temperature and rainfall were associated with HFMD and mean temperature had stronger influence on HFMD than rainfall (t =4.687,P ＜ 0.01 ; t =2.258,P ＜ 0.05).Conclusions HFMD has obvious seasonality.Mean temperature and rainfall are the main factors affecting this seasonality.
