Oncology is extensive in contents,covering a wide range of organs,systems and clinical specialties.Here,we discuss the feasibility and necessity of flipping the classroom teaching through the introduction of Oncology and through the implementation of flip classroom teaching for oncology graduate students,this paper analyzes the evaluation of the classroom teaching by the teachers and students,and compares the assessment results of students under different teaching methods.The results show that the flipped class can promote students' initiative learning,promote students' classroom participation,and help students to internalize and consolidate their knowledge of oncology in the theoretical teaching of graduate oncology.

Objective To study the characters of oscillatory potentials (OPs) of electroretinogram (ERG) after methanol intoxication in rats. Method The SD rat models of methanol intoxication were established and divided into control group, 3-day intoxication group, 7-day intoxication group. The changes of OPs of ERG were recorded in a dark room. Results The total amplitudes of 3-day and 7-day intoxication groups decreased approximately 50% compared with that of the control group, while the schedule de-layed approximately 16% and 61%, respectively. Conclusion The characters of methanol intoxication in rats included delay in schedule and decline in the total amplitude of OPs.

To change the medicine teaching model and cultivate the medicine students to have Tongji feature ( good backgrounds,valuing practices,knowing scientific research,examining patients ),our teaching and research section takes PBL method in theory and clinical teaching.During 5 years,we have built PBL teaching system of oncology successfully,including the high quality of PBL teaching plans and the PBL teachers who have rich experience and innovative thinking,and the object evaluation system of PBL teaching.It is a constructive action of PBL teaching method for reform of teaching in oncology.PBL teaching method in oncology will be consummated persistently.

Objective:To analyze the distribution of UGT1A1 gene polymorphisms in Chinese Han patients with extensive-disease small cell lung cancer(ED-SCLC),and evaluate the correlation between UGT1A1 gene polymorphisms and toxicity and efficacy of irino-tecan(CPT-11) based regimen in the patients with ED-SCLC. Methods: The analysis of UGT1A1?28 and UGT1A1?6 gene poly-morphisms was performed in 67 patients with ED-SCLC admitted in our hospital from June 2011 to January 2013. The 67 cases with ED-SCLC treated with irinotecan(CPT-11) based regimen were enrolled to observe the adverse events and efficacy during the chemo-therapy, including objective responserate rate ( ORR) , progression free survival ( PFS) and overall survival ( OS) . The incidence of different genotypes was compared. Results:The distribution of UGT1A1 genotypes in the 67 patients was follows:UGT1A1?28 wild-type (WT) genotype TA6/6 (56, 83. 6%), heterozygous genotype TA6/7 (11, 16. 4%);UGT1A1?6 wild-type (WT) genotype G/G (45,67. 2%), heterozygous genotype G/A (22,32. 8%). No significant difference of PFS and OS was observed between the differ-ent genotypes. The incidence of grade 3 and 4 delayed diarrhea and neutropenia in the patients carrying UGT1A1?6 G/A was higher than that in those with WT genotype (36. 4% vs. 6. 6%, P<0. 05;27. 2% vs. 4. 4%, P<0. 05, respectively). The incidence of grade 3 and 4 thrombocytopenia in the patients carrying UGT1A1?28 TA6/7 was higher than that in those with WT genotype (27. 2%vs. 1. 8%, P<0. 05). The patients simultaneously carrying UGT1A1?28 TA6/7 and UGT1A1?6 G/A were prone to suffering 3 and 4 delayed diarrhea and neutropenia. Conclusion: UGT1A1 polymorphisms may predict the adverse events of CPT-11 in ED-SCLC, while can not predict the efficacy of CPT-11.

The recombination clones contained CFP, LTB-ST foreign gene were screening by PCR using individual bacterial colonies as template, the aimed band was amplified from positive clones, the result was as well as plasmid PCR. The selecting of agrobacterium transformed with recombination plasmid could also use this method of PCR screening of individual bacterial colonies. The result of individual bacterial colonies PCR was as well as that of PCR using bacterial solution as template. It showed that the method individual bacterial colonies PCR was an efficient, easy one that characterized recombination clones.

Hepatitis E, caused by hepatitis E virus (HEV) infection, usually leads to an acute clinical course, and is the most common diagnosis among cases of acute viral hepatitis. From 2008, there have been increasing reports of chronic HEV infection in immunocompromised patients such as organ transplant recipients. Without intervention with antiviral treatment, approximately 60% of HEV infections in organ transplant recipients evolve into chronic HEV infections. Of these chronic hepatitis E patients, 10% may develop liver fibrosis and progress to liver cirrhosis. This article reviews chronic HEV infection and treatment in organ transplant recipients.

ObjectiveTo observe the expression of nerve growth factor(NGF)and its receptors (TrkANGFRand P75NTR) in hepatocytes and to explore the biological effects of exogenous P75NTR protein on hepatocytes.MethodsL02 hepatocytes were cultured in vitro.The expression of NGF,TrkANNGFR and P75NTR in L02 cells were assessed by immunocytochemistry and fluorescent quantitation polymerase chain reaction (PCR). The effects on L02 cell proliferation by exogenous P75NTR,NGF,NGF+ P75NTR,anti-TrkANGFR and anti-P75NTR were detected by XTT assay.The effect of exogenous P75NTR on L02 cell apoptosis was measured by flow cytometry (Annexin V/PI) and the effect of exogenous P75NTR on L02 cell cycle was determined by flow cytometry (PI).ResultsL02 cell proliferation was promoted by P75NTR and in dose-dependent manner.The A value of NGF group and NGF+ P75NTR group was 0.4916±0.0565 and 0.5839 ± 0.0733,respectively,and there was statistical significance compared with control group (0.3601 ± 0.0310,P＜0.05).The A value ot anti-TrkANGFR group was 0.2689±0.0229,and there was statistical significance compared with control group (P=0.003).The A value of anti P75NTR was 0.3524 ± 0.0312,and there was no statistical significance compared with control group (P=1.000). Exogenous P75NTR had anti-apoptosis effect on L02 cells,the antiapoptosis effect was strongest when 100 ng/ml P75NTR was added and the expression quantity was 3.70 ±0.26.However there was no statistical significant compared with control group (4.10 ± 0.62,P=1.000).P75NTR affected the cell cycle S phase of L02 cells and in dose-dependent manner,which was inverted U shaped curve.The effect was strongest when the concentration was 100 ng/ml (25.60 ±0.40) and there was statistical significance compared with control group (20.10 ±1.00,P=0.000).Exogenous NGF,P75NTR and NGF + P75NTR up regulated the gene expression of NGFmRNA,TrkANGFRmRNA and P75NTR mRNA in L02 cells and there was statistical significance compared with control group (P＜0.05).There was no significant difference in the gene expression of NGFmRNA,TrkANGFFR mRNA and P75NTR mRNA between anti-TrkANGFR,anti-P75NTR groUp and control group (P＞0.05).Conclusion NGF and its receptors TrkANGFR and P75NTR were expressed in L02 cells.The appropriate dose of exogenous P75NTP protein promoted L02 cells proliferation via TrkANGFR/P75NTR heterodimer signal pathway.
