Objective To compare the results of emergency clinical training for medical students and to put forward some suggestions.Methods Toatlly 207 medical students of Grade 4 studied in the first people' s hospital of Shanghai Jiaotong university from 2009 to 2011 were divided into the traditional group (n =90 ) and the experimental group (n =117 ).The students in the experimental group participated in emergency clinical training in summer vacation while those in the traditional group did not.Questionnaires about their self-learning ability,clinical communicating ability and critical thinking ability after training the were conducted and the data were analyzed by descriptive statistical analysis.Results One hundred and five effective questionnaires were recovered from the experimental group,with the recovery rate 89.7％ and 62 effective questionnaires were recovered from the traditional group,with the recovery rate 68.9％.The scores about clinical communicating ability and critical thinking ability of the experimental group were significantly highcr than those of the traditional group [ (79.45 ± 9.354)vs.(75.87 ± 9.926),(263.38 ± 30.925 ) vs.(251.36 ± 23.679),P ＜ 0.05 ].However,there was no significant difference in scores about self-learning ability between the two groups [ ( 153.97 ± 23.725 ) vs.( 149.83 ± 13.891 ),P ＞ 0.05].Conclusion Emergency clinical training is helpful to improve medical students' clinical communicating ability and critical thinking ability.It is worth popularizing.

ObjectiveTo analyze the results of implementing the tutorial system for medical interns, and to put forward some suggestions. MethodsThe medical interns and the doetors selected as tutors were asked to do questionnaires to study the tutorial system's feasibility and effectiveness. Simultaneously, we adopted the Objective Structured Clinical Examination ( OSCE ) to assess its process and resuits. Results74.3％ of the students and 75.5％ of the doctors think that they need the tutorial system,73.2％of the students think that this system can train better clinical skills,67.9％ of the doetors think that they can review the knowledge learned through teaching. Implemented after one year, students' OSCE scores are improved. ConclusionTutorial system for medical interns has achieved preliminary success, and the preparatory work and related-system building need to be further improved.

Inhibition of tumor neovascularization (angiogenesis) has become one of the novel therapeutic strategies for tumor, and natural inhibitor of angiogenesis has been highlighted in this field. Thrombospondin-1 (TSP-1), as an important extracellular matrix component which can influence endothelial cell adhesion, migration, and proliferation, is reported to be a potent inhibitor of angiogenesis in vivo. It will be valuable to use its active peptides or small fragments from TSP-1 in antiangiogenesis therapy.

ObjectiveTo explore the clinical value of combined detection of serum carbohydrate antigen 19-9(CA19-9) ,carcinoembryonic antigen( CEA), alpha-fetoprotein(AFP) and ferritin(Fer) in the diagnosis of digestive system neoplasm. Methods183 cases of digestive system neoplasm and 40 patients with benign digestive diseases and 40 healthy contrll were selected. The serum tumor marker levels were detected by electrochemiluminescence assay. ResultsIn digestive system neoplasm patients and patients with benign digestive disease, the level of the tumor markers were increased,while the detection rate of four joint detection test than a single tumor marker in digestive system neoplasm were significantly increased. ConclusionCombined detection of serum CA19-9, CEA, AFP, and Fer level, could significantly improve the sensitivity of diagnosis of digestive tract tumors.

Objective To compare the efficacy of 10-days sequential treatment( including rabeprazole,amoxillin, levofloxacin and tinidazole) and traditional trigeminy therapy (including rabeprazole, amoxillin and clarithromy-cin) for the eradication of helicobacter pylori ( Hp). Methods 90 patients with Hp positive who were detected by 14C urea breath test or gastroscope Hp test were randomly divided into two groups: the therapeutic group and the control group. The therapeutic group was treated with rabeprazole,amoxillin at first 5 days,rabeprazole,levofloxacin and tinidazole at the second 5 days,while the control group was treated with rabeprazole,amoxillin and clarithromycin for 10 days. The 14C urea breath test was detected after course of treatment finished in a month. Results The eradication rate of 10 days sequential treatment was 93. 3% and that of control group was 75. 6% ,and the difference between two groups was significant(P <0.05). Conclusion Comparing with traditional trigeminy therapy,the 10-days sequential treatment comprising rabeprazole and levofloxacin could achieve a higher eradication rate of Hp.

0.05). CONCLUSION: Two methods are of good reproducibility and sensitivity, and can be used for the quality control of DNJ in Cortex Mori.

Objective To explore the clinical manifestation and laboratory examination of chronic diarrhea in children with acquired immunodeficiency syndrome(AIDS) and analyze the reasons that causes the chronic diarrhea in children.Methods Clinical data of 7 patients (male 4 cases,famale 3 cases)with AIDS with manifestation of chronic diarrhea among the 17 cases were diagnosed as AIDS in Beijing children′s hospital from Jan.1999 to Dec.2006.The time of diarrhea,degree of dinrrhea,characteristic of stool,accompaniment symptom,laboratory examination were retrospectively analyzed.Results The average onset age was 6 years old(from 2-9 years old).The average time of diarrhea was 6 months(from 1-16 months).Four cases main complained with chronic diarrhea,3 cases came to the hospital because of fever,cough and wasting;6 cases with diarrhea,7 cases with malnutrition and anemia,5 cases accompanied hypokalemia and metabolic acidosis,6 cases had delay in growth and development,2 cases with abnormal stool routine exam,1 case with positive stool culture of fungi.All patients were with lower CD4,5 cases with lower CD4/CD8.Conclusions Chronic diarrhea is a common symptom in children with AIDS,and usually accompanied by obvious delay in growth and development,malnutrition and anemia,the reasons that causes the chronic diarrhea are consi-dered to be related with both the opportunistic infection and HIV infection.
