1.Contrastive Linguistics and Contrastive Language Teaching
Journal of Kunming Medical University 2013;(11):128-132
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.
2.Celecoxib inhibits proliferation of polycystic kidney cyst lining epithelial cells through blocking mitogen-activated protein kinase signal transduction pathways
Academic Journal of Second Military Medical University 1985;0(06):-
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.
3.Overview of Chinese medicine in prevention of non-small cell lung cancer recurrence and metastasis after surgery
International Journal of Traditional Chinese Medicine 2015;(11):1047-1050
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.
4.Occlusion on implants---Is there a problem?
Journal of Practical Stomatology 2015;(2):266-277
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.
5.Radiotherapy and tumor immunity
Journal of International Oncology 2016;43(11):855-857
Infiltrated immune cells and cytokines in the tumor microenvironment may play different functions that appear tightly related to clinical outcomes.Radiotherapy mainly kills tumor cells through radiobio-logical effect,meanwhile it can indirectly change tumor immunologic microenvironment,and has a local or dis-tant anti-tumor immunological effect cooperatively.Animal experiments and clinical trials of radiotherapy com-bined with immunotherapy display well applied prospects,but the mode of radiotherapy in combined treatment needs further research.

7.The role of FOXO transcription factors in neuronal apoptosis after cerebral ischemia
International Journal of Cerebrovascular Diseases 2009;17(3):220-224
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.

Chinese Journal of Laboratory Medicine 2014;(9):673-677
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.
9.Silver ion dressing effects on healing of chronic wound
Chinese Journal of Tissue Engineering Research 2013;(42):7494-7500
BACKGROUND:Silver ion dressing can reduce tissue necrosis, accelerate the epithelial formation, relieve the patient’s pain during the treatment, and strengthen various growth factors for wound repair, which is based on the theory of wet healing theory. It has obvious advantages for chronic wound healing, such as anti-infection and promoting wound granulation and epithelial hyperplasia.
OBJECTIVE:To observe the efficacy of silver ion dressing used in healing of chronic wound.
METHODS:A total of 40 patients who had chronic wounds were selected from Tangshan Branch Hospital of Nanjing General Hospital of Nanjing Military Command. Al cases were divided into two groups. The treatment group was treated with silver ion dressing, and the control group was treated with routine dressing. Secretions extracted from wound were used for bacterial culture prior to and 7, 14, and 21 days after treatment. Healing condition and velocity were observed and wound pain was assessed using visual analog scale.
RESULTS AND CONCLUSION: The detection rate of wound bacteria in the treatment group was significantly lower than that of the control group (P<0.05). And the time of healing was shorter in the treatment group than the control group (P<0.05). Wound pain during dressing change was relieved (P<0.05). Medical costs showed no difference between the two groups (P>0.05). No adverse reaction occurred in the two groups. These findings indicate that silver ion dressing used in chronic wound healing can prevent infection and promote wound granulation or epithelial hyperplasia. It can effectively promote wound healing and has no bad reaction.
