ABSTRACT
Objective:To investigate relationships between social support and dysfunctional cognition, personality disorder in patients with somatoform disorder.Methods:One hundred and four patients with somatoform disorders and 97 healthy subjects were evaluated with the Social Support Rating Scale (SSRS), Dysfunctional Attitudes Scale (DAS) and Personality Diagnostic Questionnaire (PDQ-4). Social support ratings were compared between patients and healthy controls.The relationship between social support and dysfunctional cognition, personality disorder were analyzed.Results:The scores of social support in all dimensions of patients with somatoform disorder(total score of social support(37.18±8.12), objective social support(8.49±2.83), subjective social support(21.90±5.44), social support utilization(6.79±1.85)) were significantly lower than those in the healthy control group(total score of social support(41.82±6.87), objective social support(9.92±3.38), subjective social support(24.32±4.25), social support utilization(7.59±1.31))( P<0.05). In patients with somatoform disorder, there was a significant negative correlation between the total score of SSRS and the scores of DAS ( r=-0.245, P<0.05) and personality disorder tendency ( r=-0.292, P<0.01). Social support utilization had a significant predictive effect on dysfunctional cognition ( B=-5.384, P=0.007). Conclusion:Social support of patients with somatoform disorder is correlated with dysfunctional cognition and personality disorder tendency, which provides the basis for psychological intervention such as group and family psychotherapy.
ABSTRACT
Objective To examine the characteristics of dysfunctional attitudes in patients with so?matoform disorders and to delineate the relationship between dysfunctional attitudes and personality disorder tendency. Methods Sixty?four outpatients with somatoform disorder and 52 healthy individuals were recrui?ted and asked to complete the Personality Diagnostic Questionnaire( PDQ?4) and the Dysfunctional Attitudes Scale( DAS ) for the evaluation of their personality disorder tendency and cognitive characteristics. DAS scores were compared between patient and control groups. The relationship between DAS and PDQ?4 was e?valuated by comparing DAS scores of patients with and without personality disorder tendency and by correla?ting patients’ total scores of DAS and PDQ?4. Results Patients with somatoform disorder(150.13±31.75) showed significantly higher scores of DAS than healthy controls(121.62±20.30). Moreover,patients with per?sonality disorder tendency exhibited significantly higher scores in the total score of DAS and scores of five factors including vulnerability, absorption/exclusive, compulsion, dependence and cognitive philosophy ( P<0.05) . Finally,a positive correlation was found between total scores of DAS and PDQ?4( r=0.535, P<0.01) and the correlation coefficients between the total score of DAS and Cluster A( r=0.545) and C scores( r=0.625) were significantly higher than that of Cluster B score( r=0.317).Conclusion Patients with somato?form disorders have cognitive distortion,which is correlated with personality disorder tendency.
ABSTRACT
Objective To establish RT-PCR-RFLP method for studying the genotype of wild mea-sles virus strains isolated from Tianjin area from 2002 to 2008. Methods Isolations of measles virus were carried out by tissue culture method from urine and throat swab specimens collected from suspected cases. RNA were extracted from the virus specimens. The 594 bp fragment of C terminal of the N (nucleoprotein) gene was amplified by one-step RT-PCR, then the PCR products were digested with Bcn I , separated on agarose gel electrophoresis and then analyzed by the method of RFLP (restriction fragment length polymor-phism). In addition, above results were compared with DNA sequencing. Phylogenetic tree was plotted based on the results for the genetic relationship and distance analysis. Results Sixty-nine measles virus strains were isolated from 189 specimens from 2002 to 2008, of which the C terminals of N gene were all de-tected positive. Among the 69 strains of measles virus isolates, 98.55% (68/69) belonged to Hla sub-geno-type which was the predominant sub-genotype, and only one strain (1.45%) belonged to H1b sub-genotype by RFLP analysis which was in accordance with the results by DNA sequencing method. Phylogenetic tree analysis indicated the H1a sub-genotype measles virus strains should be further divided into 2 clades, and the variation fluctuated between 0.2% and 3.8%. There were transmission chains caused by different virus strains co-cireulation. Conclusion A genotype, H1a and H1b sub-genotype can be identified by RT-PCR-RFLP assay specically based on the restriction enzyme Bcn I .The RT-PCR-RFLP assay can be a rapid, simple, accurate and efficient method for large-scale surveillance of measles virus strains in China.
