Objective To study the therapeutic efficacy of combined interventional chemotherapy and intravesical instillation of mitomycin on preventing bladder cancers from recurring after local ablation. Methods 28 patients with superficial bladder cancers were randomized into combined interventional chemotherapy and intravesical instillation of mitomycin or intravesical instillation of mitomycin alone for preventing recurrence after local ablation.The result was assessed by ? 2 test. Results The patients have been followed up for 12~26 months (mean 21 months).1 case has had tumor recurrence in the combined modality therapy group and 4 in the intravesical instillation alone group,the tumor recurrence rate being 7% (1/14) and 29% (4/14) respectively(P

Objective to evaluate the validation of atypical depression among Chinese outpatients with depressive episodes and explore the role of atypical depressive symptoms in distinguishing bipolar depression from unipolar depression.Methods Structural clinical interviews with self-compiled questionnaires were performed on 276 outpatients with current depressive episode,then comparison of clinical characteristics including age of onset,gender proportion,seasonality,comorbidity of anxiety disorder,bipolar property,psychotic features,number of depressive episodes,and maximum duration of depressive episode were conducted between atypical (defined by DSM-Ⅳ-TR) and nonatypical depression.then the rate of atypical depressive symptoms were compared between unipolar depression and bipolar depression.Results The proportion of atypical depression among all the participants was 23.9%.Compared to nonatypical depression,psychotic features were more likely seen in atypical depression (20.0% vs 9.1%,P<0.05),but no difference was found in other clinical features between atypical and nonatypical depression.Except mood reactivity,atypical symptoms including oversleeping(45.5% vs 26.0%),overeating (22.7% vs 15.4%),weight gain(24.1% vs 14.6%),leaden paralysis (56.6% vs 47.2%),interpersonal rejection sensitivity(66.7% vs 34.2%) were more likely to occur in bipolar depression than in unipolar depression,the difference was statistically significant for oversleeping and interpersonal rejection sensitivity (P < 0.05).Patients with mood reactivity differed little from those without mood reactivity in other clinical features.No association was found between mood reactivity,leaden paralysis and other criteria symptoms of atypical depression.Conclusion-Atypical depression might be a useful concept,but its diagnostic criteria needs further validation among Chinese population.

ObjectiveTo explore the personality traits of Han Chinese women with recurrent depression.MethodsAssessed by the Big Five Inventory (BFI),a comparison research was conducted between 118 Han Chinese women with recurrent depression and 65 sex,race and culture background matched health controls.Results Han Chinese women with recurrent depression scored lower in extraversion,conscientiousness and openness ( 17.93± 5.43,30.24 ± 5.94,30.03 ± 7.33 ) than matched controls ( 20.72 ± 3.79,31.94 ± 3.84,32.75 ± 5.32 ),while scored higher in neuroticism (21.38 ± 3.91) than the later one ( 27.57 ± 6.19 ).A binary logistic regression model,with group (case vs.control) as dependent variable and extroversion,conscientiousness,openness and neuroticism as independent variables,was built to assess each personality dimension's independent impact on recurrent depression.It came out to be that only extraversion ( OR =0.881,95% CI =0.083-0.966,P=0.007) and neuroticism ( OR =1.225,95% CI =1.134-1.323,P < 0.01 ) were statistically significantly associated with recurrent depression ( P< 0.05 ).ConclusionIn the big five personality model,extraversion and neuroticism might act as independent personality traits to impact Han Chinese women with recurrent depression in a positive and negative way respectively.

Because of the anomalous points distributed in the image, gene chip is hard to be distinguished effectively in fact. This article offers some arithmetic of image processing by VB such as increasing contrast, self-adapt thresholds, two-values and searching for spares and disperse templet which can distinguish all kinds of gene chip quickly, well and truly.

Objective To explore the association of methyl-CpG-binding protein2 (MeCP2) polymorphisms with female schizophrenia in Chinese Han population.Methods By using the technology based on microarray Chip,gene polymorphism analysis of 4 locus located in the gene MeCP2 was performed in 126 schizophrenia patients fulfilled with DSM-Ⅳ-TR criteria for schizophrenia and in 144 healthy controls.Chi square test was used to compare the inter-group differences of genotypic and allelic distribution.Haplotype case-control association analysis based on linkage disequilibrium was conducted using SNP stats online software after the data was screened.The significance of results was corrected by permutation test.Results To the point of Locus rs1616369 which located in Gene MeCP2,the distribution of the genotype G/A between two groups(24.8% vs 34.3%) reached significance (P<0.05) ; rs3027933,genotype G/C(25.6% vs 34.8%),P<0.05 ; rs17435,genotype T/A(25.6% vs 35.5%),P < 0.05 ; rs2239464,genotype C/A (58.5% vs 71.8%),P< 0.05.The distribution prevalence of Haplotype GCCA was 0.1581 in case group,and 0.2389 in control group,reached significant difference(P<0.05).Conclusion As to female MeCP2 gene,the genotype on the four locations might associate with the onset of schizophrenia,MeCP2 might be susceptibility gene of female schizophrenia.The Haplotype GCCA maybe the protective factor.

Objective To explore the risk factors of antidepressant treatment emergent suicidal ideas or attempted suicide among patients with bipolar depression. Methods Out of 623 patients with bipolar disorder visiting between June 2006 and June 2009,68 who was initially diagnosed as unipolar disorder and treated with antidepressants were retrospectively surveyed. Suicide and activation symptoms during the process of antidepressant treatment were estimated based on the cases record and semi-structural interviews. Unconditional bivariate logistic regression was conducted to analyze the potential risk factors. Results Of 68 patients,7 ( 10. 3% ) experienced antidepressant treatment emergent suicidal ideas and 4 ( 5.9% ) attempted suicide after 2 to 63 ( 17.45 ± 5.90 )days following the treatment. The antidepressant treatment emergent suicidal ideas or attempted suicide were related to the suicidal level before treatment (P= 0. 012, OR = 2. 072 ) and the combined use of benzodiazepine (P =0. 043, OR = 0.236). Clinical subtypes, gender, age, symptoms feature, types of antidepressant and antidepressanttreatment emergent activation symptoms had little impact on the antidepressant treatment emergent suicidal ideas orattempted suicide (P > 0.05 ). Conclusion The antidepressant treatment emergent suicidal ideas or attempted suicide among patients with bipolar depression are positively related to the suicidal level before treatment while negatively associated with the combined use of benzodiazepine.

Objective:To optimize the preparation technic of Chuanxiong Rhizoma with vacuum steam method, and to investigate the anti-inflammatory and analgesic activity of Chuanxiong Rhizoma decoction pieces with Central Composite Design-Response Surface Method. Methods:Taking the content of ferulic acid as the evaluation index and the moistening temperature, moistening time and vacuum time as the observation indexes, the moistening technic of Chuanxiong Rhizoma was optimized by Response Surface Method, and selected the optimized plan. The anti-inflammatory and analgesic activities of Chuanxiong Rhizoma were investigated by auricle swelling induced by xylene and writhing induced by glacial acetic acid. Results:The optimum vacuum moistening technic was that the softening temperature was 80 ℃, the softening time was 50 min and the vacuum time was 45 min. The content of ferulic acid in Chuanxiong Rhizoma produced by this technic is highand could decreased the times of wrinkle reaction induced by acetic acid in mice, prolonged the latent period, and obviously or partially inhibitied the ear swelling degree induced byxylene in rats. Conclusions:The Response Surface Method technic of Chuanxiong Rhizoma is easy to operate with high accuracy. The vacuum steam treatment was more obvious than traditional technology group. It provides reference for the subsequent production of Chuanxiong Rhizoma decoction pieces and have the certain value for its promotion and application.
