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.Analysis of urogenital Ureaplasma urealyticum infection and their drug tolerance
International Journal of Laboratory Medicine 2008;29(5):412-413
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.
4.Effects of transcranial and trans-spinal low frequency magnetic stimulation on the expression of growth associated protein-43 after spinal cord injury
Chinese Journal of Physical Medicine and Rehabilitation 2012;34(8):565-569
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.

6.Study of small intestinal bacteria overgrowth in patients with minimal hepatic encephalopathy
Chinese Journal of Postgraduates of Medicine 2010;33(34):3-5
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.
7.Investigation on Preparation Process of Xiaoyaosan Oral Liquid(Radix Bupleuri,Radix Angelicae Sinensis,etc.)
Chinese Traditional Patent Medicine 1992;0(11):-
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.
8.Vitiligo staging based on clinical and skin computed tomography features
Chinese Journal of Dermatology 2015;48(6):404-407
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.
9.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.
10.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.
