Objective To investigate the relationship between Post stroke depression (PSD) and Post stroke cognitive impairment (PSCI) using proton magnetic resonance spectroscopy.Methods 82 patients of acute stroke,which were met with the third edition of the Chinese Classification of Mental Disorders (CCMD-Ⅲ) and expert consensus of cognitive impairment since January 2012 to December 2012,Select continuously 82 patients who are hospitalized in our hospital due to acute stroke from January 2012 to December 2012 from Zhongnan Hospital of Wuhan University,were examined by 1H-MRS in one month.They were divided into PSD and PSCI simultaneously (n =19),PSD (n =21),PSCI (n =22) and control group (n =20).Results The differences between PSD and PSCI was not significant.On hippocampus japonicas,the Cho/Cr ratio in patients of A group (left (1.05 ± 0.10),right(1.18 ± 0.15)),showed higher than those in B group (left (0.84 ± 0.10),right (0.88 ± 0.08)),C group (left(0.88 ±0.08),right (0.87 ±0.07)),D group(left(0.87 ±0.06),right(0.89 ±0.06)).The difference was statistically significant.PSD and PSCI promoted each other in influencing Cho/Cr ratio.Conclusion There is no significant relationship between PSD and PSCI in the produce of disease,and they can promote each other in hippocampus japonicas Cho/Cr ratio.

Objective:To investigate the feasibility,effectiveness and safety in the treatment of symptomatic middle cerebral artery stenosis with stenting.Methods:Twelve patients with middle cerebral artery stenosis were treated with stenting from August 2005 to December 2006.Among these patients,9 were male and 3 were female.The meam(SD)age was 69(5.3)years(range 56 to 81 years).The mean(SD)stenosis degree was 84.2%(3.7)(range 50% to 99%).All patients were successfully treated with balloon-expanded stents.and there was not any severe complications.Results:The rate of residual stenosis after the procedures was≤20%.No cerebral ischemic symptoms recurred in the patients over a 6-to 18-month follow-up period.Conclusions:Endovascular stenting is a safe and effective approach in the treatment of symptomatic middle cerebral artery stenosis,and its short-term effect is significant.

Objective: To study the effects of deguelin on proliferation and apoptosis of human breast cancer cell line MCF-7 and on phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) signaling pathway. Methods: After treatment with 0, 1, 5, 10, 15 and 20 μmol/L of deguelin for 6, 24, 48 and 72 hours, the proliferation inhibition rate of MCF-7 cells was measured by cell counting kit-8 assay. Apoptosis rate of MCF-7 cells was detected with Annexin V-fluorescein isothiocyanate/propidium iodide double staining by flow cytometry and the apoptotic morphology was observed under a transmission electron microscope. After treatment with 0, 1 and 5 μmol/L of deguelin for 6 hours, 5 proteins involved in the PI3K/Akt signaling pathway were examined by Western blot analysis. Results: Deguelin at doses of 5, 10, 15 and 20 μmol/L inhibited the proliferation of MCF-7 cells at 6, 24, 48 and 72 hours. There was a significant difference in each group compared with the control group (P<0.01). The inhibitory effect was more marked with increasing concentration and duration of treatment. There were statistical differences (P<0.05) among 5, 10, 15 and 20 μmol/L groups. However, 1 μmol/L of deguelin had no obvious effects on the proliferation of MCF-7 cells at 6, 24, 48 and 72 hours, showing no significant difference compared with control group (P>0.05). Deguelin at doses of 5, 10, 15 and 20 μmol/L induced apoptosis of MCF-7 cells at 6 hours. There were significant differences (P<0.01) in the early and late apoptosis rate between the treated groups and the control group. The typical apoptotic MCF-7 cells were observed under the transmission electron microscopy. However, 1 μmol/L of deguelin had no apparent effect in inducing apoptosis of MCF-7 cells at 6 hours. After treatment with 5 μmol/L of deguelin for 6 hours the expression of phosphorylated phosphatase and tensin homologue deleted on chromosome 10 (PTEN) (Ser380), phosphorylated 3-phosphoinositide-dependent protein kinase 1 (PDK1) (Ser241), phosphorylated Akt (Thr308) and phosphorylated glycogen synthase kinase-3β (GSK-3β) (Ser9) proteins were significantly reduced in MCF-7 cells, while there was no significant change in the expression of total Akt protein. However, after treatment with 1 μmol/L of deguelin for 6 hours, there was no apparent change in the expression of these 5 proteins. Conclusion: Deguelin can inhibit the phosphorylation of GSK-3β (Ser9) via inhibition of the phosphorylation of PTEN (Ser380) and PDK1 (Ser241) pathway, thus inducing apoptosis and inhibiting proliferation of MCF-7 cells.

By using the glyoxylic acid to induce fluorescence histochemieal method, the catecholamines (CAs) in the adrenal medulla of rats were demonstrated。The CAs fluorescent intensity was measured with Leitz MPV-2 microflurophotometer. The results showed that the CAs fluorescent intensity in the adrenal medulla of rat with traumatic shock was much decreased than that of the normal control group. The CAs fluorescent intensity was in the adrenal medulla obviously increased after using electroacupuncture (EA) at "Renzhang" and "Chenjiang" points. Our results also indicated that the EA might play a certain role in regulating the level of plasma CAs during the traumatic shock process. Therefore, The depletion of CAs was reduced from the rat's adrenal medulla, this could be one of the benificial factors in using the EA antitraumatic shock.

OBJECTIVE:To explore how to establish good procedure,system and mode of drug management,dispensing and application,in order to provide reference for risk management and rational use of rabies vaccine. METHODS:The use of rabies vaccine and storage temperature monitoring in our hospital during 2013-2014 were analyzed statistically,and risk management and use of rabies vaccine in our hospital were analyzed,and management measures and attentions were put forward. RESULTS:The amount of vaccinum rabiel (Vero cell) and human rabies immunoglobulin in our hospital were increased in 2014,compared to 2013. The position labeled with #1 in storehouse and that of labeled with #1 and #2 in dispensing store could meet the storage condi-tion of rabies vaccine. Risk management could be carried out in fields of drug requisition,cold chain management,drug manage-ment and drug dispensing. ADR should be paid attention. CONCLUSIONS:It is of significance to develop risk management and ra-tional medication guidance of rabies vaccine.

Objective:To establish a method for isolating tumor infiltrating dendritic cells(TIDC)from mice models of Lewis lung cancer by positive selection using anti-CD11c magnetic beads.Methods:A total of 1.0?10~6 Lewis lung cancer cells were subcutaneously injected into a C57BL/6 mice at the lateral abdominal wall to establish the mouse model of lung cancer.TIDC were isolated positively using anti-mouse CD11c magnetic beads;they were labeled by anti-mouse CD11c,and then the purity of the isolated cells was tested by FACScan flow cytometer.The cells were also double labeled by PE-conjugated MHC-ⅡmAb and FITC-conjugated CD83 mAb or FITC-conjugated CD86 mAb to analyze the phenotype of cells by FACScan flow cytometer.Results:The positive selection using anti-CD11 c magnetic beads isolated(1.73?0.31)?10~6 TIDC from each gram of Lewis lung cancer tissue,which accounted for(2.18?0.29)%of the cells in the tumor tissues.The purity of TIDC was 96.49%.Electron microscope showed that the isolated TIDC had the typical character of DC cells.The positive rates of MHC-Ⅱ,CD83 and CD86 molecules in TIDC surface were(51.25?4.21)%, (3.48?0.34)%and(3.07?0.65)%,respectively.Conclusion:The positive selection using anti-CD11c magnetic beads is highly effective,simple,and economic,and is worth popularizing.

To explore the structure and function of thioredoxin glutathione reductase (TGR) from Schistosoma j aponi-cum ,the homologous model of TGR in Schistosoma j aponicum was constructed by Swiss-Pdbviewer based on sequence and structure alignment .The potential substrates binding sites of TGR were analyzed and these sites of various TGRs were also as-sessed .Our results showed that the homologous model of Schistosoma japonicum TGR based on Schistosoma mansoni TGR structure was proved to be reasonable by PROCHECK program .Analysis of binding sites showed that NADPH and GDS bind-ing sites were conservative sites and GSH binding site was a specific site for parasite .Our data suggested that inhibitors which work in NADPH and GDS binding sites of other various TGRs may also interact with TGR form Schistosoma j aponicum .GSH binding region might be one of the potential targets for design of specific inhibitors of parasite TGRs .In addition ,C-terminal of TGR plays an important role in electron transfer and may participate in the binding of the substrate .Thus compound inhibiting swing of C-terminal could effectively restrain Schistosoma j aponicum TGR activity .

Objective:Investigate the relation between the phosphorylation of FOXO1 and the apoptosis and the proliferation of lymphoma cells and to clarify its specific mechanism.Methods:The lymphoma cells Namalwa and Jurkat were treated with PI3K inhibitor wort mannin or etoposide or Wortmannin plus etoposide for different times-pan and at different concentration.The inhibition rates for cell growth of lymphoma cells were examined by XTT assay.Apoptosis were detected by flow cytometry.The expressions of p-Akt,p-FOXO1,FOXO1 and Bim were determined by Western blot analysis.Results:Wortmannin induced apoptosis of Jurkat cells and Namalwa cells and inhibited their survival effectively.The growth inhibition rate and the apoptosis rate of lymphoma cells induced by Wortmannin plus etoposide were higher than those induced by etoposide alone.After treated with Wortmannin,phosphorylation of FOXO1 remarkably reduced and bim markedly increased.Conclusion:The dephosphorylation of FOXO1 inhibits proliferation of Jurkat cells and Namalwa cells,promotes their apoptosis and enhanced the sensitivity of Non-Hodgkin lymphoma cells to etoposide.Bim activated by FOXO1 promotes cell apoptosis.

Objective To evaluate the outcome of Stage Ⅱ nasopharyngeal carcinoma(NPC) trea-ted by conventional fractionation radiotherapy. Methods From January 1990 to May 1999,216 patients with untreated stage Ⅱ NPC were irradiated by 6 MV photons and 9-12 MeV electrons with linear accelera-tor. Of 26 patients with residual lesions after 70 Gy irradiation, 18 received intracavitary brachytherapy and 8 received stereotactic irradiation boost. Results The 10-year overall survival (OS) of patients with T2 N0 M0, T1N1M0 and T2N1M0 disease were 90%, 80% and 75.2% (χ2 = 3.26, P =0. 200), respectively. The corresponding disease-free survival(DFS) and distant metastasis-free survival(DMFS) were 79% ,60% and 62.6% (χ2 = 5.87, P = 0.053) ;90% ,74% and 68.0% (χ2 = 7.09, P = 0. 030), respectively. In uni-variate analysis, T stage had no impact on OS, DFS or DMFS (χ2 = 0.44, P = 0. 500 ; χ2 = 0.44, P = 0.500 ; χ2 = 0.25, P = 0. 610), while N stage significantly influenced DFS and DM FS (χ2 = 5.86, P = 0. 015 ; χ2 = 5.31 ,P = 0. 021). Multivariate analysis showed that N stage was an independent prognostic factor for DFS and DMFS(χ2=5.03,P=0.025;χ2=6.47,P=0.01). Conclusions Stage Ⅱ NPCwithposifivelymph node treated by radiotherapy alone is inadequate. In order to improve DFS and DMS, combined chemo-radio-therapy should be considered.
