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.

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.

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 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.

Prostate cancer is one of the most common malignant tumor of male population in the West.Via binding to androgen response element in the genome and interacting with co-regulators,androgen receptor can participate in the development of prostate cancer and the convertion from androgen dependent prostate cancer to androgen independent prostate cancer.Chromatin immunoprecipitation ,coupled with PCR , chip,and high-throughput sequencing ,makes a huge progress in the study on the downstream target genes of androgen receptor and provide a new way to understand the molecular mechanisms of castration -resistant prostate cancer.

98%. Conclusion The developed method is simple, reproducible and easy to operate. The solvent is cheap, with low boiling point and easy to recovery property.

Object To study the technological conditions of refining ?-linolenic acid by short-path distillation (SPD). Methods According to the characteristic of SPD, the effect of the operating parameters, such as the distillation temperature, the system pressure, the feeding rate, and the agitating speed, were studied on the purity of ?-linolenic acid. Results The appropriate process conditions for the purification of ?-linolenic acid by SPD are: distillation temperature 90 ℃—120 ℃, pressure 0.3 Pa, feeding temperature 60 ℃, feeding rate 90—100 mL/h, and rotating speed 150 r/min. Conclusion Refining ?-linolenic acid by SPD is a simple and convenient method. It is easy to achieve industrialization.

Aim: To investigate the mechanism of anti-proliferation, anti-migration and anti-angiogenic effects of tanshinone ⅡA. Methods: In this study, MTT, 2-D/3-D migration, tube formation, PCR, chick embryo chorioallan-toic membrane (CAM) were used to evaluate the anti-proliferation, anti-migration and anti-angiogenic effects of tanshinone ⅡA. Results: Tanshinone ⅡA significantly inhibited the proliferation of human breast cancer line MDA-MB-435 with an IC_(50) of 21 nmol/mL And it is showed that breast cancer cells migration was effectively prevented by tanshinone ⅡA at 5 and 6 nmol/mL in a wound healing assay and a transwell migration assay. In ad-dition, tanshinone ⅡA inhibited the tube formation of newborn cattle aortic endothelial cells( NCAECs) after 2 h co-incubation with MDA-MB-435. These effects were not due to the inhibition of NCAECs proliferation; because tanshinone ⅡA non-selectively inhibited NCAECs growth with an IC_(50) of 124 nmol/mL Tanshinone ⅡA showed dose-dependent inhibitory effects on mRNA expression of VEGF and two transcription factors (HIF-1α/c-Myc) . Tashinone ⅡA was also found to inhibit angiogenic in vivo in the CAM assay. Conclusion: These results suggest that tanshinone ⅡA may exert its anti-proliferation, anti-migration and anti-angiogenic effects through down-regu-lating two transcription factors and VEGF. These novel anti-proliferations, anti-migrations, anti-angiogenic activi-ties of tanshinone ⅡA are likely to contribute to its cancer chemopreventive and therapeutic potential, especially in the treatment of breast cancer.

Recurrence and metastasis are main causes ofsurgical treatment failure of non-small cell lung cancer.In prevention of non-small cell lung cancer recurrence and metastasis,Chinese medicine has achieved a certain effect. It has been proved by clinical use of Chinese patent drugs, compound modification based on syndrome differentiation, integrated traditional Chinese and western medicine treatment, and molecular mechanism of anti-recurrence and metastasis, though there are still some problems. This article reviews the recent clinical and experimental research status.
