Objective To improve the quality and santdard of medical French bilingual teaching and promote the learning ability of the students in medical universities. Medthods Analogy between English and French was applied to the intervention of bilingual teaching in the clinical students who were learning medical French. The advantages and disadvantages were analyzed.Results The students could apply their prior English to medical French learning and make progress in both languages. A series problems were found during the practice:arrangement of teaching contents, lack of teaching materials and shortage of teaching staff. Conclusion Analogy between English and French is an effective teaching method in both foreign language teaching and bilingual teaching. But the expected teaching goals can be achieved only by formulating reasonable teaching contents and strategies and mproving teachers’ quality.

Objective:To investigate whether celecoxib(CXB), a specific COX-2 inhibitor,can inhibit the proliferation of cyst lining epithelial cells through blocking mitogen-activated protein kinase(MAPK) signal transduction pathway.Methods: Primarily cultured cells were treated with different concentrations of CXB(0,2.5?10~(-6),5?10~(-6),1?10~(-5),2?10~(-5),3?10~(-5),4?10~(-5),5?10~(-5)mol/L) and the proliferative status was evaluated by BrdU assay.The levels of vascular endothelial growth factor(VEGF) were measured by enzyme-linked immunosorbent assay(ELISA);the production of proliferating cell nuclear antigen(PCNA) and phosphoMAPK were measured by real-time reverse transcription-PCR assay;and the expression of PCNA,MAPK and phospho-MAPK protein was detected by Western blotting.Results: BrdU assay revealed that CXB inhibited cell growth in a concentration-dependent manner;the maximum inhibition rate([63.9?1.2]%) was found when cells were treated with 2?10~(-5) mol/L CXB for 24 h.VEGF secretion by cyst lining epithelial cell was reduced by CXB in a concentration and time-dependent manner.The mRNA and protein levels of PCNA,phospho-MAPK in CXBtreated group were lower than those in control group(with no CXB treatment).Conclusion: CXB can obviously inhibit the proliferation of cyst lining epithelial cell and the secretion of VEGF,which might be through interfering with the phosphorylation of MAPK and partly blocking MAPK signal transduction pathway.

Based on the research project of the French language teaching reform in Kunming Medical College——the Application and Analogy of Modern Foreign Languages Pedagogy,the successes and disadvantages of the visual-audio-oral course were studied.The teaching reform's purpose and focal points were primarily introduced.Then,the successful experiences of academic period arrangement,teaching materials selection,in-class instruction and students' academic achievements were elaborated.Finally,by making a comparison of students' French language proficiency between the present experimental classes and the former ordinary classes,a few disadvantages of the reform were interpreted.

OBJECTIVE:To investigate outpatients' cognition(including knowledge,attitude and behavior)on adverse drug reactions(ADR),and to analyze the influential factors of ADR cognition.METHODS:An on-the-spot questionnaire survey was conducted in which a total of 488 outpatients sampled from our hospital from May to December in 2007 were investigated and the data analyzed statistically.RESULTS:The correct rate was 36.6% for the questions related to cognition on ADR.70.5% of the patients investigated had a poor cognition on ADR.The factors influencing patients' cognition on ADR included educational background,ADR experience,pharmacists' guidance on medication,source of medicine knowledge,occupation,doctors' guidance on medication,community ADR lecture,and gender.CONCLUSION:The outpatients have a poor cognition on ADR.Both doctors and pharmacists should offer guidance on medication and give lecture in community to inform patients the knowledge about rational administration and ADR.

Objective To investigate the Lemple-Zie complexity (LZC) characteristics in patients with Alzheimer' s disease(AD),mild cognitive impairment(MCI) and normal elderly,and the possibility of differentiating AD,MCI and normal elderly by LZC.Methods Electroencephalogram (EEG) of 30 AD patients,30 MCI patients and 20 normal elderly with eyes closed in rest state were recorded.In acquired EEG data,2048 points(10.14 s)of each channel were selected for LZC calculation by Matlab 7.0 software.Results (1) The average LZC values in AD,MCI and control groups were 0.396 ± 0.036,0.470 ±0.051,0.523 ±0.055 respectively.As compared with control group,the values in AD and MCI groups were decreased (F =43.092,P =0.000).(2) LZC values of AD in all channels (from 0.373 ± 0.042 to 0.430 ±0.083),whole brain,bilateral hemispheres,frontal and temporal areas were significantly lower than those in the normal group (from 0.498 ± 0.067 to 0.566 ± 0.059 ; t =3.602-8.747,P =0.000-0.010),and showed the significant decline(＞ 23％)in bilateral anterior middle temporal,frontal areas,the left parietal area.(3) Except the T6 channel,LZC values of AD groups in the remaining channels(from 0.373 ±0.042 to 0.418±0.063),the whole brain,bilateral hemispheres,frontal and temporal areas were significantly lower than those in the MCI group(from 0.455 ± 0.072 to 0.489 ± 0.063 ; in T5 channel,t =2.038,P =0.041,the others t=4.178-7.424,all P=0.000).(4) LZC values of MCI groups in the whole brain,bilateral hemispheres,temporal areas,parietal areas,the left frontal area were notably lower than those in the control group.Conclusions With the decline of the cognitive function,the EEG complexity value shows the parallel change.It suggests that the EEG complexity value can reflect the change of brain function in the duration from normal age to dementia in some degree; The MCI patients with abnormal LZC values in temporal and frontal lobes have a certain degree relation with the occurrence of AD.

Oral rehabilitation restores form and function and impacts on general health.Teeth provide a discriminating sense of touch and directional specificity for occlusal perception,management of food with mastication and swallowing,and awareness of its texture and hard-ness.Peripheral feedback for control of jaw muscles includes the enamel-dentine-pulp complex and mechanoreceptors in the periodontal tis-sues.The implications of feedback from periodontal and other intra-oral mechanoreceptors as well as changes in central representation are significant for function and adaptation to oral rehabilitation.With implants,in the absence of the periodontium and periodontal mechanore-ceptor feedback,fine motor control of mastication is reduced,but patients are still able to function adequately.Further,there is no signifi-cant difference in function with full-arch fixed prostheses on teeth in comparison with implants.Predictable implant outcomes depend on bone support.Optimum restoration design appears to be significant for bone remodelling and bone strains around implants with occlusal loading. Finite element analysis data confirmed load concentrations at the coronal bone around the upper section of the implant where bone loss is com-monly observed clinically.Load concentration increased with steeper cusp inclination and broader occlusal table and decreased with central fossa loading and narrower occlusal table size.It is recommended that occlusal design should follow a narrow occlusal table,with central fossa loading in intercuspal contact and low cusp inclination to minimise lateral loading in function and parafunction.Acknowledging these features should address potential problems associated with the occlusion in implant therapy.

Protein kinase B (PKB), a serine/threonine kinase Akt, regulates many vital cellular functions, such as cell apoptosis, cell cycle progression and glucose metabolism, etc. Akt/PKB carries out these functions mainly through phosphorylation of a number of cellular substrates. As one of the important substrates of Akt, FOXO transcription factors have attracted more and more attention in regulating cell cycle and apoptosis. FOXO transcription factors are primarily regulated by the phosphatidylinositol 3-kinase/Akt signal pathway via phosphorylation,and re-positioning accompanied by sub-cellular distribution. This article reviews the role of FOXO transcri ption factors in neuronal apoptosis after cerebral ischemia.

Objective To investigate the prevalence of small intestinal bacteria overgrowth (SIBO)in patients with minimal hepatic encephalopathy (MHE). Methods Ninety patients with cirrhosis and 20 healthy volunteers were studied. All of them were assessed with glucose hydrogen breath test (GHBT) to detect SIBO. And number connection test (NCT-A, NCT-BC) and digit symbol test (DST) were used to diagnose MHE. Results One case (5.0%) out of 20 healthy volunteers was SIBO and none was MHE,and 28 cases (31.1%) out of 90 cirrhosis patients were SIBO and 38 cases (42.2%) were MHE. Twenty-one (55.3%,21/38) cases were diagnosed as SIBO among these patients with MHE,and 7 cases (13.5%,7/52)were diagnosed as SIBO among these patients without MHE. There was significant difference between cirrhosis with MHE and cirrhosis without MHE (x2 = 17.90,P＜ 0.01 ). Conclusions Patients with cirrhosis have a higher prevalence of SIBO. The incidence rate of SIBO in cirrhosis patients with MHE is more than that without MHE.

Objective To investigate the status of urogenital Ureaplasma urealyticum (Uu) infection and their drug tolerance in our area,so as to guide rational administration for the clinic.Methods Mycoplasma culture and drug susceptibility test were performed for 771 patients with urogenital infaction. The culture,identification and drug resistance of mycoplasma were carried out with one complex mycoplasma kit.Results The positive rate of Uu was 49.9%. The proportional percentage of males was 12.5% and the Uu positive rate was 22.3%,for females,the proportional percentage and Uu positive rate was 87.5% and 60.6% respectively. The population aged 21-40 was susceptible to Uu infection. The most sensitive antibioties to Uu was clindamycin (95.12%),followed by doxycycline (87.57%) and roxithromycin (86.24%).Conclusion The difference of Uu drug sensitivty was significant in different areas. So it is necessary to select antibioties by drug sensitivity. Clindamycin,doxycycline and roxithromycin may are used as preferred antibioties in treating Uu infection in our area. The drug-resistance status of spectinomycin and lincomycin was serious.

Objective To compare the effects of transcranial and trans-spinal low frequency magnetic stimulation (MS) on the expression of growth-associated protein-43 (GAP-43) in the spinal neurons of rats after spinal cord injury (SCI). Methods Forty-five Sprague-Dawley female rats were divided randomly into a transcranial magnetic stimulation (TMS) group,a trans-spinal cord magnetic stimulation group and a model control group with 15 in each group.Another 6 rats served as a normal control group.Spinal cord injury at the T9-10 level was modeled according to the modified Allen's method.The rats in the two MS groups received magnetic stimulation at 0.5 Hz and 75％ of the maximum output intensity ( 1.9 T) of the magnetic stimulator beginning 24 h post injury.They received 30 pulses daily for 28 days while the rats in the model control group were not exposed to MS.Basso-Beattie-Bresnahan (BBB) scale scores and motion evoked potentials (MEPs) were measured at the 1st,7th,14th,21 st and 28th day post injury.The expression of GAP-43 protein was studied using immunohistochemical methods and semi-quantified by Western blotting. Results At the 4th week post injury the average BBB scores in the model control group,the TMS group and the trans-spinal cord magnetic stimulation group were all significantly different. MEP amplitudes decreased significantly in all groups after the injury,and the latency was prolonged,but there were no significant differences among groups at any time point.GAP-43 expression also increased after SCI,and it was significantly higher in the MS groups than in the model control group at 4 weeks. Moreover,the expression of GAP-43 in the trans-spinal cord MS group was significantly greater than in the TMS group.Conclusion Magnetic stimulation can promote nerve regeneration and improve locomotor recovery after spinal cord injury,at least in rats.The effect of trans-spinal cord magnetic stimulation is superior to that of TMS.The mechanism may be related to the activation of central pattern generators.
