It should adoptstudent-centeredteaching approaches, such as case-based teaching, task-based teaching, medical humanistic practice, and autonomous learning. It should also optimize the evaluation methods. The purpose of the teaching model is to create a real English learning context for medical humanities in which students can improve their English proficiency, enrich their medical humanities literacy, and expand their international horizon as well.
4.Glutamate transporter-1 and cerebral ischemia
International Journal of Cerebrovascular Diseases 2013;21(12):942-946
Glutamate is an essential excitatory neurotransmitter which regulates brain functions.An increase in extracellular glutamate could excessively activate ionotropic glutamate receptors,initiate calcium overload,and lead to cell death after cerebral ischemia.Glutamate transporter-1 (GLT-1) is one of the major glutamate transporters expressed predominantly in astrocytes.Astrocytes also express the enzyme glutamine synthetase (GS) which converts the glutamate to glutamine; the latter is then 'recycled' into neurons.Pretreatment with ceftriaxone (CEF),ischemia and intermittent hypobaric hypoxia could lead to neuroprotection by increasing the expression of GLT-1 and regulating the activity of glutamate transporter in brain.

OBJECTIVETo evaluate the outcomes of T3a prostate cancer with unfavorable prognostic factors treated with permanent interstitial brachytherapy combined with external radiotherapy and hormone therapy.
METHODSFrom January 2003 to December 2008, 38 patients classified as T3a prostate cancer with unfavorable prognostic factors were treated with trimodality therapy (brachytherapy + external radiotherapy + hormone therapy). The prescription dose of brachytherapy and external radiotherapy were 110 Gy and 45 Gy, respectively. The duration of hormone therapy was 2-3 years. The endpoints of this study included biochemical failure-free survival (BFFS), distant metastasis-free survival (DMFS), cancer-specific survival (CSS), and overall survival (OS). Survival curves were calculated using the Kaplan-Meier method. The Log-rank test was used to identify the prognostic predictors for univariate analysis.
RESULTSThe median follow-up was 71 months. The serum pre-treatment prostate-specific antigen (PSA) level ranged from 10.0 to 99.8 ng/ml (mean 56.3 ng/ml), the Gleason score ranged from 5 to 9 (median 8), and the percentage of positive biopsy cores ranged from 10% to 100% (mean 65%). The 5-year BFFS, DMFS, CSS, and OS rates were 44%, 69%, 82%, and 76%, respectively. All biochemical failures occurred within 40 months. The percentage of positive biopsy cores was significantly correlated with BFFS, DMFS, and OS (all P=0.000), and the Gleason score with DMFS (P=0.000) and OS (P=0.001).
CONCLUSIONST3a prostate cancer with unfavorable prognostic factors presents not so optimistic outcome. Hormone therapy should be applied to prolong the biochemical progression-free or metastasis-free survival. The percentage of positive biopsy cores and the Gleason score are significant prognostic factors.

In the present study, terminal-restriction fragment length polymorphism (T-RFLP) technique was applied to assess the diversity and tissue distribution of the fungal endophyte communities of Alpinia officinarum collected from Longtang town in Xuwen county, Guangdong province, China, at which the pharmacological effect of the medicine plant is traditional considered to be the significantly higher than that in any other growth areas in China. A total of 28 distinct Terminal-Restriction Fragment (T-RFs) were detected with HhaI Mono-digestion targeted amplified fungal nuclear ribosomal internal transcribed spacer region sequences (rDNA ITS) from the root, rhizome, stem, and leaf internal tissues of A. officinarum plant, indicating that at least 28 distinct fungal species were able to colonize the internal tissue of the host plant. The rDNA ITS-T-RFLP profiles obtained from different tissues of the host plant were obvious distinct. And the numbers of total T-RFs, and the dominant T-RFs detected from various tissues were significantly different. Based on the obtained T-RFLP profiles, Shannon's diversity index and the Shannon's evenness index were calculated, which were significantly different among tissues (P < 0.05). Furthermore, two types of active chemicals, total volatile oils by water vapor distillation method and galangin by methanol extraction-HPLC method, were examined in the each tissue of the tested plant. Both of tested components were detected in all of the four tissues of the medicine plant with varying contents. And the highest was in rhizome tissue. Correlation analysis revealed there were significant negative correlations between both of the tested active components contents and calculated Shannon's diversity index, as well as the Shannon's evenness index of the fungal endophyte communities of the host plant (P = 0, Pearson correlation coefficient ≤ -0.962), and significant positive correlations between both of the tested active components contents and 325 bp dominant T-RF linkage to Pestalotiopsis (P = 0, Pearson correlation coefficient ≥ 0.975). In conclusion, A. officinarum is colonized by diverse fungal endophytes communities. The diversity of the fungal endophytes was found in the A. officinarum varied with differences of the tissue types of the host plants and was closely correlated with the accumulation of main active components, total volatile oils and galangin contents in the host plant tissue.
