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 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.

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 investigate the effect of enteral nutrition support one week before surgery and postoperative periods on the postoperative immune function and nutritional status in old patients with gastric cancer. Methods:A retrospective analysis was con-ducted on 77 stomach cancer patients who were admitted and received surgical treatment in our hospital. Among the patients, 38 re-ceived enteral nutrition support one week before surgery and early period of postoperation, and were labeled as the experimental group. The remaining 39 patients did not receive enteral nutrition support one week before surgery and early period of postoperation, and were named as the control group. The levels of prealbumin, albumin, transferrin, CD4+T (%), CD8+T (%), and CD4+/CD8+cells were also an-alyzed before surgery and 1 d and 8 d after surgery. Results:No statistical differences in the gender, age, site of tumor, TNM staging, and differentiated degree were found between the two groups. All operations were successful and the patients recovered well after sur-gery. In the nutritional status, the levels of prealbumin, albumin, and transferrin in the patients of the two groups had no significant dif-ference (P>0.05). On the first day after the surgery, the levels of prealbumin, albumin, and transferrin were significantly low in both groups;the control group had lower levels than the experimental group (P<0.05). No differences in the levels of CD4+T (%), CD8+T (%), and CD4+T/CD8+T cells were found between the two groups (P>0.05). On the first day after surgery, the levels of CD4+T (%), CD8+T (%), and CD4+T/CD8+T cells were significantly low in both groups;the control group had lower levels than the experimental group (P<0.05). Conclusion:Elderly patients with gastric cancer who receive appropriate enteral nutrition support one week before sur-gery would have better immune function and nutritional status after surgery than those who did not, and the recovery of old patients im-proved.

Background:The incidence of ulcerative colitis (UC)in developed countries is higher than that in developing countries,which may be related with westernized lifestyle,especially high animal protein and low complex carbohydrate diet. With the increased high fat and meat intake,synthesis and secretion of bile acid in liver is also increased,which may have an impact on the occurrence of UC. Aims:To investigate the expressions of farnesoid X receptor (FXR)and G protein-coupled bile acid receptor 5 (TGR5)in patients with UC. Methods:Thirty patients with active UC from January 2013 to June 2016 at the Affiliated Jiangning Hospital of Nanjing Medical University were enrolled,and 30 healthy subjects were served as controls. Expressions of FXR and TGR5 were determined by immunohistochemistry. Results:Compared with control group,expression of FXR was significantly decreased in UC patients (4. 63 ± 2. 07 vs. 6. 91 ± 2. 62,P =0. 00),however,no significant difference in expression of TGR5 was found between the two groups (6. 70 ± 2. 90 vs. 6. 11 ± 2. 44,P = 0. 40). Expression of FXR was significantly increased in right hemicolon colitis than in left hemicolon colitis (P < 0. 05). Conclusions:There is a significant decrease in FXR in active UC patients,indicating that FXR may have some role in the pathogenesis of UC,however,TGR5 may have no obvious effect in the pathogenesis of UC.

Objective To study the T cells lineage polymorphism of TCR BV CDR3 in the peripheral blood of ankylosing spondylitis (AS) patients,in order to provide experimental basis for the immunological patho-genesis study of AS.Methods Twenty-six subfamilies of CDR3 T cells of TCR BV in the PBMC of AS patients were amplified by RT-PCR method,then TCR BV CDR3 lineages polymorphism were analyzed by immunization scanning spectrum.Results TCR BV CDR3 scanning spectrum of 20 active AS patients showed abnormal distribution peak,including monoclonal,oligoclonal/oligoclonal trend,skewing peak and irregular abnormal peak.Among them,some subfamilies of 18 patients showed oligoclonal/oligoclonal trend expansion,BV16 and BV18 two subfamilies of one case showed monoclonal expansion.Most spectral type of PBMC TCR BV CDR3 in five normal controls showed Gauss distribution.Conclusion TCR BV CDR3 lineage have significant characteristic polymorphism and spectrum drift characteristics in the peripheral blood of AS patients,which further indicate that T cells has plaied an important role in the immunological pathogenesis of AS.Monoclonal/oligoclonal expansion of T cells may be autoreactive T cells in nature and they may be involved in the pathogenesis of AS.
