Long educational system is an effective form in training high-level medical talents.Doctor-patient communication skill is one of tbe basic qualifications for 8-year program medical students.Standardized patients can be applied in training and evaluating of the 8-year program medical students'ability to deal with doctor-patient relationship so as to cultivate their communication competence.

Human kerotinocyte growth factor (hKGF) gene amplified by PCR was inserted into the shuttle vector pAdTrack-CMV to get the recombinant plasmid pAdTrack-CMV-hKGF, which was linearized with Pme I and transferred into Escherichia coli BJ5183 containing the adenoviral bone plasmid pAdEasy-1 to obtain the recombinant adenoviral plasmid pAdEasy-hKGF. The recombinant adenoviral plasmid was then transfected into HEK-293 cell lines via Lipofectamine 2000 to package and amplify the recombinant adenovirus containing hKGF gene detected by PCR. The recombinant adenovirus produced could effectively infect HaCat cells. The result of Western blotting showed that HaCat cells infected with the recombinant adenovirus expressed and secreted hKGF protein.

This study is to investigate the effect of recombinant hFGF-10 adenovirus on the proteome of HaCat cells, and to speculate further the possible mechanism of the effect of hFGF-10 on HaCat cells via differentially expressed proteins identified. Two-dimensional gel electrophoresis (2-DE) combined with tandem time-of-flight mass spectrometry was applied to identify the differentially expressed protein spots on the 2-DE maps of the whole-cell proteins from Ad infected and rAd-hFGF-10 infected HaCat cells. The mRNA and protein levels of the differentially expressed proteins were confirmed with semi-quantitative RT-PCR and Western blotting. The results showed that the 2-DE maps with high resolution were obtained, and four selected differentially expressed proteins involved in cell apoptosis, cytoskeleton regulation and protein degradation were identified with MALDI-TOF/TOF. The mRNA and protein levels of one of the differentially expressed proteins, VDAC2, were up-regulated in HaCat cells infected with the recombinant hFGF-10 adenovirus. The differentially expressed protein, VDAC2, may be related to the bioactivities of hFGF-10.

AIM: To investigate the correlation between the expression of neuron-specific protein and apoptosis in the process of differentiation from rat bone marrow stromal cells into neuron with brain-derived neurotrophic factor (BDNF). METHODS: The 5th passage MSCs were induced by BDNF and 2-mercaptoethanol (?-ME), respectively. At 1 h, 6 h, 12 h and 24 h, nestin, neuron specific enolase (NSE), microtubulease associated protein (MAP)-2 and glail fibrillary acidic protein (GFAP) were detected by Western blotting. Cell cycle and apoptosis were examined by flow cytometry. RESULTS: Nestin and NSE of neuron-like cells induced by BDNF and ?-ME were all positive by Western blotting. At 12 h, nestin and NSE turned to negative and apoptosis was detected in ?-ME group, nestin and NSE still positive and apoptosis wasn't detected in BDNF group. Till 24 h, nestin and NSE in BDNF group were negative but apoptosis still not detected. Notably, GFAP (glial astrocyte marker) was detected and MAP-2 wasn't detected in the two induced groups. CONCLUSION: The down-expression of neuron-specific protein correspondingly with apoptosis in the process of differentiation from MSCs into neuron with ?-ME shows that apoptosis may be one of the causes of induced cell death. BDNF induction was not the cause of apoptosis. Other factors may include for the cell death in the presence of neuron-specific protein expression induced by BDNF.

Objective To evaluate the value of interventional embolism therapy for metastatic carcinoma of adrenal gland.Methods Fifty four patients with metastatic carcinoma of adrenal gland were treated with interventional catheterization perfusion and embolism therapy.Results Except one case with failure of finding the feeding artery, totally 76 sessions of interventional therapy were performed on 53 patients. Technical successful rate was 98.1% with 100% of complete release of clinical sign in 14 patients. Good deposition of iodized oil in tumor area reached 75.4% in three months after the procedure. Severe complication rate ocurred in 1.88%. Conclusion Interventional therapy seemed to be safe and effective for patients with metastatic carcinoma of adrenal gland.

Medical educational internationalization has already made teaching medical courses in English more and more important.Nephrology department in Tongji hospital affiliated to Tongji medical college,Huazhong university of science and technology has assumed the responsibility of teaching in English for medical students of five-year program,six-year program,seven-year program,eight-year program,and abroad student for several years.They practiced teaching in English in theory teaching,PBL teaching and clinical teaching according to the characteristics and requisitions of students in different educational systems.They accumulated some experiences,which was conducive to improving the quality of teaching in English.

Teaching urinary system diseases by problem-based learning method for eight-year program medical students was applied in nephrology department in affiliated Tongji hospital of Huazhong university of science and technology since 2008.They had accumulated experiences in compiling teaching plan,fostering teachers,practicing teaching and evaluating teaching.These steps may future intensify education reform on long schooling system and improve teaching quality of eight-year program.

To improve the effect of pediatrics clinical probation teaching for eight-year program medical students,the exploration and practice of case-based instruction teaching with symptoms as main line,reading reports,and application of high quality counterfeit baby simulator-assisted instruction were carried out,which could inspire students' learning interest,and contribute to the training of students'clinical and scientific thought,their self-education and clinical skills.

Ethanol can be produced from lignocellulose by first hydrolysing the material to sugars,including hexose,and pentose,and then fermenting the hydrolysate to ethanol.Hydrolysis using dilute-acid has advantages over other methods.However,compounds which inhibit fermentation are generated during this kind of hydrolysis.Therefore,it is important to focus on microorganisms metabolizing xylose and tolerating/decomposing inhibitors,on detoxification methods of hydroly- sates with low-cost and facilitated to scale-up,and different fermentation modes in ethanol production from hydrolysate.This review summarized the advance in above aspects.

Aim To study on the mitochondrial mass change in mouse thymocyte apoptosis.Method Control and Dexamethasone(DEX) groups were set;at 6h,we studied mitochondrial mass changes by NAO and Mitotracker Green(MG) staining flowcytometry and detected mitochondrial membrane potential change with DiOC_6(3) staining flowcytometry.We also used Annexin V-PE/MG double staining flocytometry to examine the mitochondrial changes in apoptosis progress.Results NAO staining results showed that 1 ?mol?L~(-1) DEX stimulation reduced the cardiolipin content of thymocyte mitochondria(P
