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.

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.

Objective To determine the stage of vitiligo according to clinical and skin computed tomography (CT) features.Methods The stage of vitiligo was determined in 200 patients according to a questionnaire-based analysis of clinical features and skin CT findings respectively.Rapid progressive stage was defined as the score for vitiligous lesions or CT findings being higher than 2,slow progressive stage as the score varying from 1 to 2,and stable stage as the score less than 1.Skin samples were obtained at lesional sites receiving CT examination from 5 patients with progressive and 5 patients with stable vitiligo,and subjected to hematoxylin-eosin (HE) staining.Results No significant difference was observed between staging results based on clinical features and skin CT findings.The patients diagnosed with progressive vitiligo based on clinical features presented with grey-white or pale white patches with elevated or obscure boundaries,or trichrome vitiligo,while those with stable vitiligo presented with milky-white or porcelain-white lesions with sharp boundaries and pigmented islands.As CT showed,progressive vitiligo was characterized by a loss of integrity in dermal papillary rings at the dermo-epidermal junction level,obscure boundaries between vitiligo lesions and surrounding normal skin,presence of highly refractive cells at the dermo-epidermal junction level in the margins of vitiligo lesions,while stable vitiligo characterized by complete absence of dermal papillary rings at the dermo-epidermal junction level,sharp boundaries between the lesions and surrounding normal skin,and presence of highly refractive dendritic melanocytes.HE staining showed plenty of CD8 + T lymphocytes in the papillary dermis in the margins of progressive vitiligo lesions,but no CD8+ T lymphocyte was seen in those of stable vitiligo lesions.Conclusions Both clinical and skin CT features can be used to determine the stage of vitiligo,and the staging results are consistent with those based on histopathological findings.

The preparation process of Xiaoyaosan Oral Liquid was investigated with the orthogonal test. As a result,the amount of water added was a main factor influencing the dip-extraction effect of crude Chinese medical materials when the oral liquid was made with the method of distillation and warm dip. It was suggested that the following process would be the best to ensure the extraction of active compo- nents:adding 10 times amounts of water,then dipping and extracting for 1.5h at 90℃ and repeating 3 times.

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.

In order to get more nutrition from outside the erythrocyte,new channels were induced by malaria par-asite.These channels play an important role in physiology of the parasitized cell.They are of interest both as potential targets in their own right and as potential drug targeting routes capable of mediating the entry of cytotoxic drugs into the app-ropriate compartment of the infected cell.It is hoped that this new anti-malarial strategy will help to create a sustainable anti-malaria-drug-development portfolio for the treatment of malaria.

OBJECTIVE:To provide reference for reasonably designing package inserts of ointment for manufacturers. METH-ODS:According to items included in Management Regulation for Package Insert and Label and Specification for Chemicals and Bi-ological Products for Treatment,labeled items in package inserts of 51 kinds of ointment for external use during Jan.-Jun. 2016 in our hospital were analyzed. RESULTS:Among the 51 kinds of ointment,39 were domestic varieties and 12 were imported variet-ies. In the package inserts of 39 domestic varieties,items with lower labeling rates were overdose,pharmacokinetics,use guid-ance,pharmacology and toxicology,with labeling rates of 2.6%,5.1%,15.4%,28.2%;while the labeling rates of imported vari-eties were 16.7%,83.3%,75.0%,100%. Compared with package inserts of imported ointment,composition,dosage and usage, adverse reactions,contraindications,precautions,drug interactions,medication for special populations were not enough detailed in domestic ointments. CONCLUSIONS:It is suggested that manufacturers consult medicine experts, list all auxiliary materials through Management Regulation for Drug Description and Label,refine and improve the labeling contents of dosage and usage,ad-verse reactions,precautions,medication for special populations,pharmacology and toxicology,overdose,etc. In addition,admin-istrative departments should strengthen the regulatory approval efforts.
