ABSTRACT
Objective:To explore the association between dopamine-β-hydroxylase (DβH), norepinephrine transporter (NET) gene polymorphisms and panic disorder(PD).Methods:The structured clinical interview for the diagnostic and statistical manual of mental disorders fourth edition (DSM-Ⅳ) axis Ⅰ disorders was administered by trained clinical psychiatrist, 139 patients with PD(PD group) and 196 healthy controls(control group) were enrolled in the study.Single nucleotide polymorphism(SNP) genotyping was performed using an improved multiplex ligation detection reaction technique.SPSS 16.0 and PLINK softwares were used to compare the allele frequency and genotype distribution.Results:(1)Compared with control group, PD group carried more G allele(76.3% vs 68.4%) and fewer A allele(23.7% vs 31.6%) in NET rs5569, and the difference was significant(χ 2=4.986, OR=0.67, 95% CI: 0.47-0.95, P<0.05). However, the correlation was no longer significant after adjusting for Bonferroni’s multiple testing( P>0.05). (2)The additive model of NET rs5569 showed a association with PD ( OR=0.68, 95% CI: 0.48-0.96, P<0.05). And the recessive model of DβH rs1611114 showed a association with PD( OR=0.42, 95% CI: 0.18-0.96, P<0.05). However, these correlations were no longer significant after adjusting for Bonferroni's multiple testing( P>0.05). (3)No matter allele or genotype, there were no significant differences in DβH (rs129882, rs1611114, rs1611115) and NET (rs2242446, rs28386840) gene polymorphisms between panic disorder group and control group(all P>0.05). Conclusion:The present study indicates that there is no significant association of DβH and NET gene polymorphisms with PD.
ABSTRACT
Anxiety disorders are one of the most common mental health problems, with a high burden of disease, high morbidity and poor adherence to medication. Cognitive-behavioral therapy (CBT) is an evidence-based type of psychotherapy that works well for anxiety disorders, but it differs greatly across individuals. Studies have shown that the efficacy of CBT for anxiety disorders is related to a variety of genes, and these genes play different roles in the efficacy of CBT. There are few relatively studies in China. By exploring the possible mechanism of these genes in the effect of CBT in patients with anxiety disorders, biological markers of anxiety disorders can be further explored, which can provide reference for domestic research in this field and be applied to the diagnosis and treatment of anxiety disorders. This paper summarized the efficacy of CBT in the treatment of anxiety disorders through HPA axis related genes, 5-hydroxytryptamine system related genes, monoamine oxidase system related genes, and neurodevelopmental related genes, and found that these genes were related to the efficacy of CBT in the treatment of anxiety disorders. It mainly included methylation of FK506 binding protein 5 promoter, methylation and polymorphism of 5-HT transporter gene, gene polymorphism of tryptophan hydroxylase 2, gene polymorphism of catechol oxymethyltransferase, and gene polymorphism of monoamine oxidase A, and so on. By studying the relationship between genetics and CBT efficacy in anxiety disorders, we can explore the related loop of how pathogenic genes of anxiety disorders affect CBT efficacy, further clarify the mechanism of genetic factors in the occurrence and development of anxiety disorders, and explore the genetic predictors of CBT efficacy.
ABSTRACT
Objective:To explore whether brain-derived neurotrophic factor (BDNF) promoter methylation status is associated with panic disorder(PD), and then assess the effect of the BDNF gene methylation status on the severity of clinical symptoms in PD.Methods:The methylation levels of the BDNF gene were compared between 111 patients with PD and 130 matched healthy controls using MethylTarget approach.In addition, the panic disorder severity scale(PDSS), Hamilton anxiety rating scale(HAM-A), and Hamilton depression rating scale(HAM-D) were respectively assessed to all subjects.Results:(1)The result showed that 7 CpG regions from the promoter regions of the BDNF gene were sequenced.However, there was no statistically significant differences between cases and controls in terms of BDNF DNA methylation status ( OR=1.087, 95% CI=0.849-1.391, P>0.05). (2)Spearman correlation analysis revealed that the hypermethylation of BDNF gene was significantly associated with the severity of the depressive symptoms in PD patients (all P<0.05). The methylation levels of BDNF gene was not significantly related to the severity of anxiety and panic in PD patients(all P>0.05). Conclusion:No association between BDNF promoter methylation status and panic disorder is found in Chinese Han population, but BDNF promoter methylation status may be related to the severity of depressive symptoms in patient with panic disorder.
ABSTRACT
Objective To understand the serum gonadal hormone level of female patients with panic disorder(PD),and to analyze its relationship with the disease severity.Methods The chemiluminescence method was adopted to detect serum gonadal hormone level in 57 female patients with panic disorder and 74 healthy subjects,the panic disorder severity scale (PDSS),Hamilton anxiety scale (HAMA) and Hamilton depression scale (HAMD) were simultaneously used to conduct the investigation.Results The serum pituitary prolactin (PRL) level in the female patients with PD had lower level was higher than that in the control group,the difference was statistically significant (P＜0.05);the luteinizing hormone (LH) and follicle-stimulating hormone (FSH) levels were lower than those in the control group(P＜0.05).The difference of the serum testosterone,estradiol and progesterone levels between the female patients with panic disorder and control group was not statistically significant (P＞0.05).The correlation analysis found that serum T level in the female patients with PD was negatively correlated with the disease severity of panic disorder,HAMD total score,retardation factor and sleep disorder factor (P＜0.05).Serum LH and FSH were positively correlated with the anxiety somatic factor of HAMA (P＜0.05).Serum FSH level was positively correlated with anxiety somatization and the sleep disorder factor of HAMD (P＜0.05).Conclusion The disorder of gonadal hormone levels may exist in the female patients with PD,and the serum T level is correlated with the PD severity and depressive symptoms.
ABSTRACT
Objective To explore the mediating effects of security on the severity of panic disorder and life events.Methods Security Questionnaire(SQ),life event scale(LES)were used to investigate 97 cases of patients with panic disorder and 108 cases of normal control group. The severity of panic disorder was assessed by panic disorder severity scale(PDSS).And the correlation and hierarchical regression analy-sis were used.Results ①The panic disorder patients' positive life stimulation(7.95±6.00)were less than that the normal control group's(18.06± 13.60),negative life stimulation and total life events stimulation ((36.64±29.98),(44.59±31.24))were higher than that of the normal control group(respectively(10.19± 7.89),(28.25±14.51)),the differences were statistically significant(all P<0.05).Panic disorder patients' interpersonal security certainty in control and total score(respectively(18.89 ± 8.66),(17.88 ± 7.58), (36.76±13.47))were lower than that the normal control group(respectively(26.64±9.33),(24.34±8.33), (50.98±15.31)),the differences were statistically significant(all P<0.01).②Severity of panic disorder and positive life events were negatively related to positive events,the total score of security,interpersonal securi-ty,certainty in control(r=-0.262--0.392);severity of panic disorder were positively related to the negative life stimulation and total life event(r=0.346,0.280)(all P<0.01).③Security played a partial mediating role between the negative life events and the severity of panic disorder(beta value decreased from 0.346 to 0.253).Conclusion The patients with panic disorder have more negative life events,lower security.And negative life events and lower security are related to the severity of panic disorder.And security plays a partial mediating effect between the negative life events and the severity of panic disorder.

ABSTRACT
Objective To study the relationship between self-esteem and childhood abuse, life events among male violent adolescent. Methods According to the modified overt aggression scale, juvenile delinquents were divided into violent group (n = 128 )and nonviolent group (n = 118 ). All the participants were investigated by Self-Esteem Scale (SES), Childhood Trauma Questionnaire-28 Item Short Form (CTQ-SF) and Adolescent SelfRating Life Events (ASLEC) and conducted correlation and regression analysis. Results ①Violent group had lower self-esteem scores ( 22.73 ± 3.30 ) than the nonviolent group ( 23.81 ± 3.30, P ＜ 0.05 ). Violent group had higher scores in physical abuse, sexual abuse, total life events, interpersonal relationship, punishment, and other (8.30 ±4.07, 7.23 ±2.26, 54.48 ±18.60, 10.09 ±3.84, 14.43 ±5.87, 4.93 ±3.15, 9.93 ±3.64), compared to the nonviolent group (7.27 ± 3.27, 6.60 ± 2.09, 45.40 ± 18.45, 8.42 ± 4.13, 11.07 ± 5.75, 3.66 ±2.81, 7.84 ±3.66, P＜0. 05). ②The self-esteem was significantly negative correlated with the childhood abuse and life events( r= -0. 143 ～ -0. 358, P＜ 0.01 ) among violent male adolescents. ③The physical abuse and punishment had significant prediction function of 15.6% on self-esteem. Conclusions Violent adolescents have low self-esteem, which is closely related to childhood abuse and adolescent life events.
