ObjectiveTo evaluate the cognitive impairment in epilepsy patients with topiramate (TPM) or valproate (VPA) treatment by using visual completion negativity of faces.Methods30 epileptic patients were divided into two groups receiving TPM or VPA, respectively. 15 healthy volunteers were included as controls. Unfamiliar grey-scale photographs of faces (front view) were used as stimuli. Two types of visual stimuli were presented randomly: pictures of complete faces, pictures of incomplete faces (the occluded part was the left-top quadrant).ResultsN170 were elicited in all participants in each condition. The peak latency of N1 elicited by incomplete faces was delayed compared with complete faces in two groups. Under incomplete faces, a decreased and delayed N170 was observed only in TPM group (P<0.05). N170 amplitude and latency did not change in VPA group (P>0.05).ConclusionChanges of N170 is more obvious in patients with TPM than VPA. Cognitive impairment was not present in epilepsy patients with VPA treatment.

Objective]To assess the effects and mechanism of triptolide(TPL)on cardiac remodeling in chronic heart failure (CHF)rats.[Methods]Thirty-two Wistar rats were divided into four groups of eight:Control group,isoprenaline(Iso)group,TPL group(Iso+TPL)and captopril group(Iso+Cap). CHF rat model was induced by Iso. In TPL and Cap group,TPL(20μg/kg·d)and Cap(15 mg/kg·d)were administrated to CHF rats for six weeks. Left ventricular internal diameter at end-diastole(LVIDd)and left ventricular internal diameter at end-systole (LVIDs)were detected. Histopathological changes of myocardial tissues of rats were evaluated byMasson staining and immunohistochemical staining of type Ⅰcollagen. Ventricular weight/body weight ratio(VW/BW), collagen volume fraction(CVF),perivascular collagen volume area(PVCA)of myocardial tissues were calculated. With real-time polymerase chain reaction and Western blot,the protein and mRNA levels of phosphatase and tensin homologue deleted on chromosome ten(PTEN)were detected.[Results]Compared to the Iso group,the levels of LVIDs,LVIDd,VW/BW,CVF and PVCA reduced in TPL and Cap group. TPL and Cap can alleviate the myocardial fibrosis in CHF rats. The expression of PTEN protein and mRNA increased markedly in the TPL or Cap treated group.[Conclusion]TPL can attenuate cardiac remodeling in Iso-induced CHF rats. The potential mechanism may be highly associated with the up-regulating of PTEN signaling pathway.

Objective To explore hypermethylation of RARβ2, GSTP1 and DAPK gene in prostate cancer tissues, and to explore its correlation with clinicopathological features of prostate cancer and its diagnostic value. Methods Hypermethylation of RARe2, GSTP1 and DAPK gene was detected by nested methylation-specific PCR (NMSP) in 57 prostate cancer (PCa) tissues and 35 benign prostate hyperplasia (BPH) tissues. The correlation between hypermethylation and clinicopathological features of prostate cancer and its diagnostic value were analyzed. Results The hypermethylation frequencies of RARβ2, GSTP1 and DAPK gene in PCa were significantly higher than those in BPH (RARβ2: 52.6% vs. 0% GSTP1: 61.4% vs. 2.9%;DAPK: 43.9% vs. 8.6%;all P<0.01). The methylation rate of RARβ2 gene was directly correlated with distinct Gleason scores and clinical stage (4~7 score vs. 8~10 score: 34.8% vs. 64.7%;stage B, C vs. stage D: 37.0% vs. 66.7%;x2=4.927 and 5.004, P=0.026 and 0.025). The methylation rate of GSTP1 gene was significantly different in patients with different Gleason scores (4~7 score vs. 8~10 score: 43.5% vs. 73.5%;x2 =11.530, P=0.001), but had no difference in patients with distinct clinical stage (stage B, C vs. stage D: 51.9% vs. 70.0%;x2=1.975, P=0.16) . There was no difference in DAPK gene methylation rate among patients with different Gleason scores and distinct clinical stage (4 ~7 score vs. 8~10 score: 39.1% vs. 50.0%;stage B, C vs. stage D: 33.3% vs. 53.3%;x2= 1.290 and 2.309, both P~0.05). GSTP1 gene showed the highest sensitivity of 61.4% (35/57)with specificity of 97.1%(34/35), while RARβ2 gene had the highest specificity of 100% (35/35) with the sensitivity of 52.6% (30/57). The sensitivity and specificity of DAPK gene were 43.9% and 91.4% (25/57 and 32/35), respeetively. When the hypermethylation of RARβ2, GSTP1 and DAPK gene were detected together, the diagnostic sensitivity was increased, but the specificity was decreased. Conclusions The aberrant methylation of RARβ2, GSTP1 and DAPK gene is correlated with tumorigenesis and progression of prostate cancer, which may be used as an effective diagnostic marker for prostate cancer.

Objective Toinvestigatetheapplicativevalueof3D-DSAandheadMRIorCTfusion technology for guiding the individualized treatment of intracranial arteriovenous malformation (AVM ). Methods Twenty-onepatientswithAVMdiagnosedwithDSAattheDepartmentofNeurosurgery,Nanjing General Hospital of Nanjing Military Command from January 2015 to May 2015 were analyzed retrospectively. All patients performed DSA,MRI,and CT scan respectively before procedure,and they also performed 3 D-DSA and MRI or CT fusion. Of the 21 patients,15 performed MRI and 3D-DSA fusion,6 performed CT and 3D-DSA fusion. According to the image fusion results of the patients,the individualized treatment regimens were further developed,including microsurgical resection,endovascular embolization,and stereotactic radiotherapy (alone or combined treatment). The patients were followed up and observed for 2 to 6 months after procedure.Results Fromthe3D-DSAwithheadMRIorCTfusionimagesofthepatientsbeforetheprocedure not only could observe the vascular architecture of AVM,the relationship between the niduses and the surrounding nerve structures,but also could precisely locate the positions of AVM with small aneurysms or tiny AVMs. According to the results of image fusion,17 patients with AVM were treated with microsurgical resection,2 were treated with interventional embolization and stereotactic radiotherapy,and 2 were treated with stereotactic radiotherapy only. Of the 17 patients with AVM underwent microsurgical resection, none experienced intracranial rebleeding during the follow-up period. The last Glasgow outcome scale (GOS)score was 5 in 13 cases,and 4 in 4 cases. One patient with AVM underwent combined stereotactic radiotherapy had intracranial rebleeding during the follow-up period,and their last GOS score was 4. The other remaining 3 patients did not have new neurological deficits or rebleeding during the follow-up period,and theirGOSscorewas5.Conclusions 3D-DSA,headMRI,andCTfusiontechnologyarenovel, the operative method is simple,and the fusion image is accurate. They can effectively develop the individualized treatment regimens for patients with AVM.
