Internal medicine(IntMed) is one of the major subjects in medical undergraduate courses.With the transformation of medical mode from experience medicine to EBM,EBM shall be melted into IntMed teaching to change traditionary teaching mode and improve the teaching quality of IntMed,which helps to culture more new medical talented persons.

0.05).3.Thirty-three point three percent of animals from parental strain group were found fibrillations potentials and the po-sitive sharp waves in gastrocnemius electromyogram,no obvious abnormal waves were found in animals from both waaF mutant and control group.Conclusions The ganglioside-like epitope in LOS of CJ is critical antigen in inducing GM1-IgG antibody and in inducing conduction block of peripheral nerve,therefore,provide a support for the molecular mimicry theory as a pathogenesis in the axonal GBS following CJ infection.

Objective To explore the relationship between tumor necrosis factor(TNF)-? promoter G238A,G308A and interferon(IFN)-?+874A/T polymorphism and susceptibility to cytomegalovirus(CMV) hepatitis.Methods A TaqMan fluorescence polymerase chain reaction(PCR) in the IFN-?+874A/T and TNF-? gene promoter region single nucleotide polymorphism was tested in the subjects,including 87 infants with CMV hepatitis and 89 children without CMV hepatitis.Results No evident difference of TNF-? +238G/A and+308G/A allele frequency was found between infants with CMV hepatitis and controls.The cases of IFN-?+874 AA,AT and TT genotype were 64,20,3 cases in the infant CMV hepatitis group,and 45,26 and 18 cases in the control group,respectively.There was significant difference in IFN-?+874 allele genotype and frequency between infants with CMV hepatitis and the control group(P=0.001,P

Objective To investigate the relapse risk assessment for patients with acute promyelocytic leukemia(APL)through testing PML-RAR? fusion gene by real-time quantitative polymerase chain reaction(RQ-PCR).Methods Relative copies of PML-RAR? fusion gene were measured in 25 patients with APL in phases of first diagnosis,complete remission(CR)and relapse.The minimal residual disease(MRD)situations were also monitored in 6 of the 25 patients.Results Different PML-RAR? fusion gene expression levels were observed in patient groups of different phases of the disease.(P

The main purpose of this study is to observe and analyze the characteristics and the clinical significance of long-term echocardiogram data in patients after mechanical aortic valve replacement operation. Fifty-five cases were recruited over 5 years after mechanical aortic valve replacement operation, with complete echocardiogram examination profiles. The 55 subjects were divided into predominate aortic stenosis group and predominate aortic regurgitation group, based on preoperative examinations. And another way of division was also carried out that according to the effective orifice area index (EOAI), the subjects were divided into three groups, i. e. , severe prosthesis-patient mismatch (PPM) group, moderate PPM group, and non PPM group. Characteristics of long-term echocardiogram data of the subjects were analyzed. Patients with aortic stenosis showed significantly decreased thickness of intraventricular septum and left ventricular posterior wall about half a year after operation (P < 0.05). Half a year after operation, patients with aortic regurgitation showed decreased left ventricular internal dimension diastole and left ventricular internal dimension systole, and increased ejection fraction (P < 0.05). Differences in mean aortic valve pressure gradient, forward blood flow across the aortic valves, and ejection fraction were not significant among those with severe PPM, moderate PPM, and non PPM groups (P > 0.05). Number of cases of ascending aorta dimension increased as time goes on and pathogenesis of other valve diseases. A conclusion could be drawn that the heart function of patients with aortic valve disease could be improved after mechanical aortic valve replacement operation, but pathologies in other valves and ascending aorta might be increased, and therefore periodical postoperative echocardiogram evaluation with long-term pharmaceutical therapy could be necessary.

Objective To investigate the proteomics differences between the high-sensitivity(HS) and the low-sensitivity(LS)groups of cervical carcinoma treated by concurrent chemoradiotherapy,and to confirm the sensitivity associated proteins in intermediate stage and advanced cervical carcinoma.Methods Fresh carcinoma tissues were collected from 10 untreated cervical carcinoma patients.According to the response to concurrent chemoradiotherapy,the tissues were classified into HS group and LS group.In the first part of our experiment,protein separation was performed using two-dimensional gel electrophoresis(2-DE)with Amersham 18 am linear pH 3-10 immobilized pH gradient(IPG)strips.The images of the gels were analyzed by PD-quest 7.0 software to find the differentially expressed protein-spots in each group.Then the differentially expressed protein-spots were incised from the gels and digested by trypsin.The peptide mass flngerprintings(PMF)was acquired by matrix assisted laser desorption/ionization time-of-flight mass spectrometry(MALDI-TOF-MS).The proteins were identified by data searched in the Mascot-database.Two differentially expressed proteins were assayed by western blot and immunohistochemical methods.Results Most of the gels were clear and successfully analyzed by PD-quest 7.0 software.Most of the protein-spots concentrated on the area of 20-100 KDa(Mw)and pH4-8.The average number of the protein-spots was 781±74 in HS group and 766±52 in LS group.The match rate was 87.6%between the two groups.Eight proteins highly in HS group but lowly expressed in LS group included hemoglobin subunit beta,caspase-14 precursor,calmodulin-like,S100-A9 protein(MRP-14),galectin-7,HSKERC4,keratin 19 and actin.Ten proteins highly in LS group but lowly expression in HS group included anti HBs antibody light-chain Fab,laminB1,WARS protein,flavin reductase,glutamate dehydrogenase 1,nuclear matrix protein 238,retinal dehydrogenase 1,AFl 65172,subunit of replicative DNA polymerase and HSP70.The higher expression of HSP70 in LS group and galectin7 in HS groups were further confirmed by western blot and immunohistochemical method.Conclusions The 2-DE gels images are successfully acquired from high-sensitivity group and low-sensitivity group of intermediate stage and advanced cervical carcinoma tissues treated by concurrent chemoradiotherapy.Some differentially expressed proteins between the two groups can be further confirmed by western blot and immunohistochemical method.

Objective To determine the significance and expression of S100A9 and NMP238 in cervical carcinoma with different concurrent chemoradiotherapy sensitivities. Methods Fresh carcinoma tissues were collected from untreated cervical carcinoma patients and preserved at -80 ℃. The tissues were classified into 2 groups:a high sensitivity group (HS) and a low sensitivity group(LS) according to their response to concurrent chemoradiotherapy. Protein was separated by 2-dimensional gel electrophoresis (2-DE). Peptide mass fingerprintings (PMF) were acquired by matrix assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) and the proteins were identified by data searching in the Mascot-database. Differential expressed proteins were assayed by Western blot and immunohistochemistry.Results Most of the gels were clear and were successfully and reproductively analyzed. Intensity and rate of S100A9 expression were higher in the HS group than in the LS group,and those of NMP238 expression were higher in the LS group than in the HS group. Conclusion S100A9 and NMP238 expression is associated with concurrent chemoradiotherapy sensitivity in cervical carcinoma.
