Objective To investigate effects of transcranial direct current stimulation on picture naming by those with Broca's aphasia recovering from a stroke.Methods Five patients with Broca's aphasia 6-12 months post-stroke served as their own controls.They all had lesions of the left frontal gyms or the basal ganglia.They received either anodic, cathodic or sham stimulation of the left Broca's area.They were then given a picture naming test.Results The average number of correct namings was 13.13 with anodic stimulation, 9.80 with cathodic and 10.15 with the sham stimulation.Compared with cathodic or sham stimulation, anodic stimulation of the left Broca's area can improve the picture-naming ability of aphasic stroke patients significantly more effectively.Conclusions Anodic stimulation of the left Broca's area can improve the picture-naming of cerebral apoplexy patients with Broca's aphasia.Such stimulation may increase the excitability of the left cortex, suggesting that the left Broca's area and its periphery play a very important role in language recovery after stroke.

Objective To investigate the toxicity of nasal membreane and ciliary of the Magnolia biondii Pamp volotile oil nanometer bangosome.Methods Toad palate and rat nasal membrane were used as experimental material,physiological saline and hydrochloride ephedrine as negative control.The Magnolia biondii Pamp volotile oil nanometer bangosome on ciliary movement were carried out using in vitro and electron microscope technique.Results The Magnolia biondii Pamp volotile oil nanometer bangosome had little cilitoxicity to toad palate and rat nasal membrane.Conc(?)sion The Magnolia biondii Pamp volotile oil nanometer bangosome had little cilitoxicity to membrane.

Objective To optimize the extraction of polysaccharides from Ophiopogon japonicus by the use of response surface methodology.Method According to the design principle of Box-Behnken, effects of extraction temperature, extraction time , extraction times and solid-liquid ratio on the extraction yield of Ophiopogon japonicus polysaccharides were studied by response surface methodology,meanwhile regression analysis of these experimental data was used by Design-Expert 8.05b software.Results The optimum extraction conditions from Ophiopogon japonicus were concluded as follows: the extraction temperature was 93℃, extraction time was 2 h, extraction times was 3 times, and solid-liquid ratio was 1:15 g/ml.Conclusion Under these conditions, the extraction yield of Ophiopogon japonicus polysaccharides is up to 5.440%, and the relative error is 7.328%.

Objective To observe the effects ofXiaotan Sanjie Decoction on ultramicrostructure in MKN-45 human gastric cancer orthotopic xenograft;To discuss its mechanism for gastric cancer. Methods MKN-45 human gastric cancer cell line was used to establish subcutaneous tumor model in nude mice as an experimental model which passed three generations of tumor source. Then OB glue was used to establish human gastric cancer orthotopic xenograft model. 40 model nude mice were divided into control group, model group (received gavage with saline),Xiaotan Sanjie Decoction group (received garage withXiaotan Sanjie Decoction) and Tegafur group (received gavage with Tegafur), 10 mice in each group. Mice in the control group were under normal diet, without medicine intervention. After 6 weeks of treatment intervention, tumor weight was detected, inhibitory rate was calculated, the ultrastructural changes of gastric cancer cells were detected through transmission electron microscopy.Results The tumor weight inXiaotan Sanjie Decoction group was significantly lower than that in control group and model group (P<0.05,P<0.01). The tumor inhibition rate was 46.2%. Under the electron microscope, MKN-45 gastric cancer cells strain changed to typical apoptosis.ConclusionXiaotan Sanjie Decoction can lead to apoptosis effects on MKN-45 human gastric cancer orthotopic xenografts. All evidences indicate that inducing apoptosis may be one of the most important mechanisms ofXiaotan Sanjie Decoction in treating gastric cancer.

Objective To investigate the diagnostic value of the quantitative analysis parameters of dynamic contrast-enhanced MRI (DCE-MRI) for prostate cancer.Methods MR examination were performed in 26 patients and correlations were made with surgical pathology following radical prostatectomy.According to the localization of pathologic specimens,ROI were drawn on areas of cancerous regions,noncancerous regions in peripheral zone and central gland to measure the values of Ktrans,kep and Ve.The values of the three parameters in different tissue were compared with Kruskal-Wallis H and Mann-Whitney U.Results Twenty six patients had prostate cancer confirmed by pathology.Data from 468 assessable regions of prostate were acquired,including 115 cancerous regions and 142 noncancerous regions in central gland,68 cancerous regions and 143 noncancerous regions in peripheral zone.Prostate cancer showed a multifocal distribution.The K,kep and Ve values were (1.04 ± 0.26)/min,(1.43 ± 0.46)/min,(0.76 ±0.12) respectively for cancerous regions in central gland,and (0.82 ±0.19)/min,(1.12 ±0.26)/min,(0.75 ± 0.14) respectively for noncancerous regions in central gland,(0.95 ±0.31)/min,(1.31 ±0.51)/min,(0.76 ± 0.13) respectively for cancerous regions in peripheral zone and (0.32 ± 0.07)/min,(0.52 ± 0.13)/min,(0.64 ± 0.14) respectively for noncancerous regions in peripheral zone.The differences among the three parameters were statistically significant (x2 =316.008,297.985,63.681,P ＜0.01).The Ktrans,kep values of cancerous regions were significantly higher than the corresponding values of noncancerous regions,respectively.Conclusion Quantitative analysis parameters of DCE-MRI contribute to the diagnosis of prostate cancer,including cancer located in central gland.

Objective To analysis the efficacy and safety of endovascular graft exclusion for patients with Stanford type B aortic dissection.Methods The clinical data of 46 patients with Stanford type B aortic dissection who received endovascular graft exclusion were analyzed retrospectively.The stents were inserted from the femoral artery to exclude the tear of dissection,and all operation were peformed under digital subtraction angiography (DSA).The operative technique,outcome and complications were observed.Results The stents were successfully performed in all patients.The length of stay in hospital time after operation was 5-20 (12.9 ± 3.4) d.Endo-leak occurred in 2 patients and relieved after re-expanding.Followed up for 2 d to 5.1 years,average 36 months,1 patient got lacunar infarction and 1 patient died after leaving hospital 2 d.The others were free from the serious complications such as aortic dissection and paraplegia.Conclusion Endovascular graft exclusion is safe and effective for the treatment of Stanford type B aortic dissection in hospital and mid-term,and can significantly improve the survival rate and quality of life.
