Objective:To construct eukaryotic expressing vector of the full length coding sequence of Bad gene and to express the gene in the basal cell carcinima A431 cells.Methods:Bad gene was amplified from Hela cell line by RT-PCR and the fragment of the cDNA was cloned into eukaryotic expressing vector pcDNA3.1-myc by ligating the fragment into XhoI and EcoRI site.The recombinant plasmid pcDNA3.1-myc-Bad was identified by DNA sequencing and restriction enzyme analysis.The gene transfection mediated by lipofectin was used to introduce the eukaryotic expressing vector of pcDNA3.1-myc-Bad into human basal cell carcinima A431 cells. After selection with G418, resistant colonies were obtained.Trasfection efficiency was identified by Western blot and SABC-FITC assay.Cell proliferation was examined by cell counting and colonogenic assay after transfection.Results:A 500 bp DNA fragment was amplified with RT-PCR.Sequence and restriction enzyme analysis showed that the recombinant plasmid pcDNA3.1-myc-Bad was constructed successfully.In human basal cell carcinima cell line A431 Bad gene was expressed.The cell proliferation was inhibited by 62.6% and colonogenesis by 39.9% by the transfection of the gene.Conclusion: Human Bad gene was successfully cloned.Transfection of basal cell carcinoma cells with the gene may inhibit the cell proliferation and colonogenesis.

Henoch-Scholein purpura(HSP)is a common systemic vasculitis of the small vessel in children,with a variety of clinical manifestations.The main diagnostic criteria include palpable skin purpura.Patients who have gastrointestinal tract as the main symptoms suffer clinically abdominal pain and gastrointestinal bleeding,they are easily misdiagnosed before skin purpura,the rate of misdiagnosis can be as high as 87.5%,and the main treatment is early application-oriented glucocorticoids.This review include etiopathogenisis,pathogenesis,pathology,clinical manifestations,auxiliary examination and treatment about gastrointestinal manifestations in HSP.

Objective To evaluate lactulose breath hydrogen test in diagnosis of small intestinal bacterial overgrowth in children.Me-thods Thirty-five children,aged 3 to 13 years old with mean (7.72?3.06) years old presented with chronic diarrhea,abdominal pain and flatulence.Among them,18 cases were male and 17 cases were female.Breath hydrogen test was carried out after the administration of a 0.5 g?kg-1 or 10 g lactulose,which was 100 g?L-1 solution.After the ingestion of lactulose,the breath hydrogen was collected in every 20 minutes and up to 3 hours.Small intestinal bacterial overgrowth was diagnosed as positive when the hydrogen concentration increased more than 20 mg?m-3 in a sample.Results Eighteen cases in 35 (51.43%) children were positive and 17 cases were negative.Among these positive cases,8 cases in 18 (22.86%) patients were typically double peaks in breath hydrogen concentrations.Among the causes of small intestinal bacterial overgrowth in children,4 cases with chronic superficial gastritis,4 cases with chronic bacterial enteritis,2 cases with malnutrition and anorexia,1 case with volvulus of stomach,1 case with massive resection of small intestine,1 case with steatorrhea and 5 cases with unknown causes.Four cases of chronic bacterial enteritis were gained remission by antimicrobial agents.The other cases were treated by lac-to-and bifidbacteria probiotics.Seven patients of the clinical systems were controlled,3 cases were improved remarkably and 4 cases were failed.Conclusions The lactulose breath hydrogen test is validated as screening test in the diagnosis of small intestinal bacterial overgrowth in children.Antimicrobial agents and bifidbacteria probiotics is effective in treatment of small intestinal bacterial overgrowth.

Objective To investigate doctor-patient communication skills status and the influencing factors so as to pu forward to develop the proposal.Methods We selected undergraduate students in fourth grade which participated in the 2012 Shanghai Jiaotong University School of Medicine OSCE examinations before practice of clinical medicine by cluster sampling 1 and we selected four western and chinese medicine hospitals randomly sample 2,which are three level of first-class hospitals in Shanghai.We design the questionnaire and observe sampling with the SEGUE framework.Application of SPSS 13.0 data for statistical analysis,descriptive statistics analysis,u test,t test,ANOVA,rank sum test and correlation analysis method.Results The test with SEGUE framework shows that the scores of samplingl were 12.54 points(out of 24),the score rate is low which was 52.25％,and in the score rate of the dimensions,the end of inquiry dimension is 4％ which is the lowest.There are significant statistical differences between different groups of influencing factors such as Medical occupation interest score and so on.There is no statistically significant difference between the SEGUE score of traditional Chinese medicine and western medicine clinical Intern.The communication skills of western medical students are higher.Doctor-patient communication skills related factors such as recognition of the importance of doctor-patient communication skills and other groups are statistically significant,the correlation coefficients are very small which is between 0.1 and 0.3.Conclusion The overall level of doctor-patient communication skills on clinical internship are not high,through the guidance and training on the occupation interest of medical students,we can strengthen the recognition of the importance of doctor-patient communication skills,so that we will improve the doctor-patient communication skills for the medical students.SEGUE framework should be used to routine medical students communication skills evaluation.

The nafion/carbon nanoparticles (CNPs) composite film modified glassy carbon electrode was pre pared by dropwise method, and the electrocatalyst of H_2O_2 at Nafion/CNPs modified electrode was investiga ted.The results show that electrocataytic activitie for detection of H_2O_2 at the modified electrode is very good.The biosensing application of CNPs was demonstrated through fabrication of an electrochemical biosensor.The biosensor was constructed by encapsulating glucose oxidase in the Nafion/CNPs composite film.The biosensor had good electrocatalytic activity toward oxidation of glucose.The glucose biosensor shows a linear range from 2.0 × 10 ~(-6) to 6.0×10~(-3) mol/L with a detection limit of 1.6×10 ~(-6) mol/L.The biosensor shows high stabili ty, good reproducibility and can avoid the commonly coexisted interference.In addition, real rat serum samples were analyzed by this biosensor with satisfactory results.

【Objective】In order to establish the foundation for transgenic mouse model,the human thalassemic gene(β654) was cloned and sequenced.【Methods】The human β654 gene was amplified by PCR,and cloned into the plasmid BGT51 in which the human β gene was cut out aforehand.The recombinant plasmid was certified by enzyme-digestion,reverse dot hybridization and sequencing.【Results】A recombinant plasmid was obtained,which contained the human β654 gene in the correct recombinant direction.Sequencing showed that the cloned insert was correct.【Conclusions】The recombinant plasmid constructed is useful for establishing a transgenic mouse.

Objective To explore effective methods of diagnosis and treatment for delayed rupture of the spleen (DRS) through retrospective analysis of 32 cases. Methods A retrospective study was done in 32 cases with DRS. The effects of CT, ultrasound and diagnostic peritoneal lavage on diagnosis of DRS was observed and compared. Results Splenectomy was performed in 26 cases, among which one died four days after splenectomy because of complicated brain injury and six given conservative treatment under continuous monitoring discharged. The mean hospitalization duration was 18.5 days. Conclusions Diagnostic peritoneal lavage can improve the positive rate of peritoneal puncture. Ultrasound is an important method for diagnosing DRS and closely monitoring the patients receiving conservative treatment.
