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 evaluate the cognitive impairment in epilepsy patients with Topiramate (TPM) or Valproate (VPA) treatment by using WAIS-CR. Methods30 untreated epilepsy patients were divided into two groups receiving TPM or VPA, respectively. All the patients were examined with WAIS-CR before and 3 months after treatment. ResultsThe IQ of TPM group decreased 3 months after treatment (P<0.05). ConclusionTPM may impair the cognitive function in epileptics reflected by decreased IQ.

Objective:To assesss the effectiveness of dapoxetine in the treatment of premature ejaculation.Methods:Both English and Chinese studies involving men with prematrue ejaculation who were treated with dapoxetine from the Cochrane Library,MEDLINE,EMBASE and CNKI,CBM,VIP between 1979 and 2009.were included in the randomized controlled trials(RCTs) and the data processed by RevMan.Results:Five RCTs involving 4433 patients were included in the Meta analysis,of which 3 were of grade A and 2 were of grade B according to the quality evaluation of methodology.Intravaginal ejaculatory latency time(IELT),patient-reported global impression of change(PGI),satisfaction with sexual intercourse(SWSI),perceived control over ejaculation(PCOE),personal distress related to ejaculation(PDRE) were used for assessment.Meta analysis based on included studies of patients having been treated with dapoxetine for 9-24 weeks showed that:(1) the difference of the patients' IELT between treatment group and control group was statistically significan [P

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 the value of dynamic contrast-enhanced MRI (DCE-MRI)and diffusion tensor imaging(DTI)in grading of glioma.Methods 3.0T DCE-MRI and DTI scans were performed in 31 patients with glioma confirmed by pathology.Capacity volume transfer constant (Ktrans ),extravascular extracellular volume fraction (Ve ),exchange rate constant (Kep ),initial area under the gadolinium concentration-time curve (iAUC),and relative fractional anisotropy (rFA)were measured in the low grade glioma (LGG)and the high grade glioma (HGG).The correlation between parameters of DCE-MRI and rFA with microvessel denisity (MVD)and microvessel structure (MVS)were performed by Spearman rank correlation analysis.Results The MVD and MVS were positive correlation with the grading of glioma.Ktrans ,Kep ,Ve ,iAUC and rFA values of the LGG were (0.02±0.01)min-1 ,1.82 (0.18-8.54)min-1 ,0.05±0.03, 2.47±1.66 and 0.55±0.22,respectively.Ktrans ,Kep ,Ve ,iAUC and rFA values of the HGG were (0.1 1±0.02)min-1 ,1.31 (0.12-7.58)min-1 ,0.28±0.10,10.84 ±6.46 and 0.28 ±0.08,respectively.The differences of all parameters between the LGG and the HGG were statistically significant,except for Kep (P <0.05 ).Ktrans ,Ve and iAUC values were positive correlation with MVD and MVS (P <0.05),and rFA values were negative correlation with MVD and MVS (P <0.01).Conclusion The quantitative parameters of DCE-MRI and DTI have important values in grading of glioma and evaluating tumor angiogenesis and microvessel structure.

Objective To explore the clinical value of plasma D -D and blood glucose change in treating patients with bone trauma.Methods Selected 200 patients with bone trauma as the observation group,60 cases of healthy persons as the control group.The plasma D -D and blood glucose of the two groups were detected,and the results were analyzed.Results The plasma D -D and blood glucose of the observation group were more than those of the control group,and it was gradually reduced from first day to third day and fifth day.The plasma D -D of the observation group was (174.7 ±40.2)μg/L,blood glucose was (5.2 ±0.4)mmol/L.The plasma D -D of first day, third day and fifth day of the observation group were (1 452.6 ±303.4)μg/L,(982.2 ±215.2)μg/L,(705.6 ± 152.9)μg/L respectively.The blood glucose of first day,third day and fifth day of the observation group were (14.2 ±2.3)mmol/L,(10.3 ±1.2)mmol/L,(7.6 ±1.9)mmol/L,respectively.The difference was statistically sig-nificant(F =3.49,P <0.05).In the observation group,the more severe injury in patients,the higher plasma D -D and blood glucose,and it was gradually reduced from first day to third day and fifth day,the difference was statistically significant(F =4.83,P <0.05).Conclusion In judging the condition of bone trauma,it is important to measure plasma D -D and blood glucose levels,and this method should be popularized in clinical use.

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.

n be used as a potential marker in the diagnosis of PCa. However, it can not be used as an index to monitor tumor progression or prognosis in PCa patients.
