ABSTRACT
Objective To explore the short term effects of five second-generation antipsychotics on the serum pro?lactin levels of first-episode schizophrenia patients. Methods Two hundred fifty first-episode schizophrenia patients were randomly divided into five groups and were then treated with risperidone, olanzapine, paliperidone, quetiapine or ziprasidone, respectively. The serum prolactin were tested at baseline, and every week following initiation of treatment. The positive and negative symptom scale (PANSS) and the treatment emergent symptom scale (TESS) were used to evalu?ate the effect and side effect of treatment. Results Repeated measure ANOVA for serum prolactin showed that the main effects of time, the main effect of group, and the interactive effect of time and group were significant (all P0.05). Conclusion The level of serum prolactin gradually increases in schizophrenia patients receiving treatment of antipsychotics. The short term effects of different second generation antipsy?chotics on serum prolactin vary differently. Risperidol and olanzapine result in the elevation of serum prolactin level in the early period of treatment.
ABSTRACT
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.
ABSTRACT
Objective To analyze the correlation of cerebral perfusion characteristics and cognitive function on patients with unipolar and bipolar depression. Methods The r-CBF imaging was detected by SPECT forall subjects. Evaluated cognitive function of subjects using WAIS-CR and WMA, and analysed data using SPSS.Results Data showed that some regions in the brain, e.g. temporal lobe, frontal lobe, hippocampus, and basal ganglia, had significant alterations of r-CBF in depressed patients as compared with healthy controls (P ＜ 0. 05 ).Compared with UPD, BPD showed increased perfusion in basal ganglia ( 0,22.73%; 4.54%, 36. 36% ) (P ＜0.05 ). Furthermore there was no significant different incognitive deficits between UPD and BPD(P ＞ 0. 05 ) , and correlations between cognitive impairment and hypoperfusion of rCBF (P ＜ 0. 05 ). Conclusion There be exist difference in r-CBF between UPD and BPD. The perfusion of r-CBF in BPD is significantly increased than that in UPD,and it suggest that hyperperfusion in basal ganglia may be the biological basis when bipolar depression turning to manic.
ABSTRACT
Objective To explore the relationships between different marital satisfaction of women with childbearing age and sexual life satisfaction, personality characteristics, coping style and social support. Method-s Three hundred and fifty-one complete cases were randomly obtained by means of ENRICH's marital satisfaction and sexual life satisfaction,EPQ,and etc,and further divided into high marital satisfaction(group A, n=170) and low marital satisfaction(group B, n=181) according to the mean score of the whole sample's macital satisfaction.Then comparisons were carried out between the two groups. Results (1)The means of sexual life satisfaction,Lacores and four indexes of social support in group A were significantly higher than those in group B(P<0.05),but P's and N's scores in group A lower than those in group B (P<0.05). (2) Stepwise multiple regression ana-lyses showed that only sexual life satisfaction (sβ=0.487) and objective social support (sβ=0. 158) entered the equation in whole sample (r=0.290). Conclusion (1) There axe significant differences of sexual life satisfac-tion, personality characteristics and social support among the women with different marital satisfactions. (2)Sexual life satisfaction, personality characteristics and social support are important influencing factors to marital satisfaction among the women.
ABSTRACT
Thyroid function [triiodothyronine(T3), thyroxine(T4), free T3(FT3), free T4(FT4),and thyroid stimulating hormone (TSH) ] were tested by radioimmunoassay in 56 depressive patients with attempted suicide, 85 patients without suicide attempt and 40 healthy subjects (controls).The serum levels of T3 and FT3 in the patients with attempted suicide were lower than those in the patients without suicide attempt and the controls ( F = 4.937 and 5.01 1, both P ＜ 0.05 ).The lower serum levels of T3 and FT3might be the risk factor of suicide in depressive patients.
ABSTRACT
Objective To explore the characteristics of both clinical symptoms and thyroid function between depressive patients with and without attempted suicide behavior. Methods Depressive patients were divided into two groups. The first group was composed of patients with attempted suicide behavior (n = 56) and the second group without attempted suicide behavior ( n = 85 ). Thyroid function (FT3, FT4 )were determined by radioimmunoassay method. The patients were evaluated by symptom checklist 90 (SCL90). Results The score of depressive factor in the group with attempted suicide [(2. 90 ± 1. 01 ) score]was higher than that of the group without attempted suicide [(2.51±0.77) score] ( ( t =2. 127, P =0. 036). The serum level of FT3 in the group with attempted suicide [(3.92 ±0. 52) pmol/L] was lower than that of the group without attempted suicide[(4.18 ±0.71) pmol/L] ( t =-2.219, P =0.028).Conclusions There were certain characteristics on clinical symptoms of depressive patients with attempted suicide. The low serum levels of FT3 might play an important role in the risk of suicide in depressive patients.
ABSTRACT
Background During the past two decades, a number of rating scales were developed to facilitate diagnosis and assessment of subjects with social anxiety disorder. One of the most commonly used scales for the assessment of social anxiety disorder is the Liebowitz social anxiety scale (LSAS). The LSAS is widely used in epidemiologic investigations and clinical researches,and its assessment in the pharmacotherapy efficacy for social anxiety disorder is superior to any other scale. So we designed this study to explore the validity and reliability of the LSAS in Chinese patients with social anxiety disorder and normal control, and to find the difference of the scores between the patients self -report version and clinician-administered version. Methods Fifty five patients meeting the DSM-Ⅳ diagnostic criteria for social anxiety disorder and 168 normal controls who were screened from 222 college students were rated by LSAS, social phobia scale and self-made General Information Forms. Results The Cronbath α of LSAS for the patients and the normal controls was 0.83 and 0.77, respectively. The 4-week test-retest reliability for total scores and its factors scores of LSAS in 31 normal controls were ranging from 0.68 to 0.79. The ROC area under curve value in discriminating the patients from normal controls was 0.87±0.03; the total score of 35 was considered to be the best cut-off score for LSAS, then its sensitivity was 0.77 and its specificity was 0.81; and no significant difference between the self-report version and clinician-administered version. Conclusions The LSAS is good in internal consistency and test-retest reliability, and has high sensitivity and specificity in discriminating the patients and the controls. There is no significant difference in the total score and each factor scores of LSAS between self-report version and clinician-administered version.
