Association analysis of the polymorphisms of dopamine-β-hydroxylase and norepinephrine transporter genes with panic disorder / 中华行为医学与脑科学杂志

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.

The relationship of peripheral blood single uncoding RNA-25-3p expression level and the sertraline efficacy in patients with panic disorder / 中华行为医学与脑科学杂志

Objective To identify potential relationship between single uncoding RNA-25-3p (miR-25-3p) expression level and the sertraline efficacy in patients with panic disorder.Methods Sixty cases of patients with panic disorder(case group) and sixty healthy-controls(control group) were collected with demographic data and peripheral venous blood before and after treatment.All the patients were evaluated using the 14-item Hamilton Anxiety Rating Scale (HAMA) and Panic Disorder Severity Scale (PDSS) at baseline,and then received sertraline treatment for 6 weeks.After six-week treatment,each patient was evaluated again with HAMA and PDSS.RT-PCR was used to detect the level of miR-25-3p expression.Results There was no significant difference in the miR-25-3p levels between control group (1.27±0.32) and case group (1.73±1.09) before treatment(t=1.53,P=0.14),but the levels in case group were much higher than that in control group after the treatment (5.72±4.13 vs 1.73±1.09,t=-2.15,P=0.04).Besides,the changes of the miR-25-3p levels were positively related with both the changes of PDSS3 and PDSS7 items before and after the treatment (r=0.60,P=0.02 for PDSS3 and r=0.61,P=0.02 for PDSS7).Conclusions miR-25-3p is associated with the drug efficacy and the outcome of some clinical symptoms of panic disorder.These findings might provide some evidence for the individualized treatment of patients with panic disorder according to regulation of gene expression in the future.

Objective To explore the association between monoamine oxidase A (MAOA) variable number tandem repeat (VNTR) polymorphism and panic disorder,and then to compare panic disorder(PD) severity patient with different MAOA VNTR genotypes.Methods The structured clinical interview for the diagnostic and statistical manual of mental disorders fourth edition (DSM-Ⅳ) Axis I Disorders (SCID-1) was administered by a trained clinical psychiatrist,135 patients with PD and 195 healthy controls were recruited.MAOA-VNTR polymorphism were measured by fluorescent tags amplification product length polymorphism technology,Chi-square test was used to compare the distribution difference between each genotype and the allele frequency distribution.Results ①Whether male or female,there was no statistically significant difference between case group and healthy control group in the genotype and allele frequencies of MAOA-VN-TR polymorphism (x2=1.574,1.894,3.588;all P＜0.05).② There was no statistically significant difference between genotypes and panic disorder severity in the male with panic disorder ((14.46± 3.53),(14.15 ± 4.02);t=-0.247,P＞0.05).③)However,there was significant difference between genotypes and panic disorder severity in the female with panic disorder((13.15±3.47),(16.57±4.34),(15.27±4.91);F=4.222,P＜ 0.05).MAOA VNTR-L/L carriers experienced more serious panic (16.57 ± 4.34) than the patient with MAOA VNTR-H/H (13.15±3.47) (P＜0.01) by LSD multiple test.Conclusion No association between MAOA-VNTR polymorphism and panic disorder is found in Chinese Han population,but low activity homozygous genotype may be related to the severity of panic disorder in female patient with panic disorder.

The 5-HTT gene polymorphisms correlated with the clinical manifestations of depression / 中华行为医学与脑科学杂志

Objective To determine the potential correlation of 5-HTT gene polymorphisms (5-HTTLPR and STin2) with clinical manifestations in depression.Methods A total of 401 depressed patients,all of Chinese Han region,were collected and genotyped by polymerase chain reactions (PCR).All patients were evaluated using a 17-item Hamilton depression rating scale (HAMD-17) and Hamilton anxiety rating scale (HAMA),and then associated analysis was applied.Results (1) The age of onset in patients with L/S genotype of 5-HTLPR polymorphism were much younger than that of patients with L/L and S/S genotype (F=3.281,P=0.039).Besides,there was also a significant difference of HAMA1 (anxious mood) scores among patients with different genotypes for 5-HTTLPR polymorphism,where the scores of those with L/S genotype were the highest (2.34±0.80,P=0.010).(2) The scores of HAMD10 (mental anxiety),HAMA1 (anxious mood),HAMA3 (fear) and mental anxiety factor were higher in patients with 12/10 genotype than patients with 12/12 and 10/10 genotype for STin2 polymorphism (2.40±0.83,2.38±0.90,1.42± 1.04,14.60±4.26 respectively;P value:0.014,0.044,0.03 and 0.006 respectively).The scores of HAMD10(mental anxiety) and mental anxiety factor were (2.11±0.77),(12.96±3.78) in the 12/12 genotype patients,and significantly lower than that in the 12/10 genotype patients (adjustedPvalue:0.018,0.006).Conclusions A positive association of the 5-HTT polymorphisms with anxious symptoms in depressed patients is revealed.These findings might provide some evidences for the clinical phenotype and optimization of depression treatment.

Intra-operative hydrotubation improves fertility of women with distal tubal occlusion after reproductive surgery.

PURPOSE: Hydrotubation has been considered to be a complimentary procedure to reproductive surgery, usually being conducted after surgery. The objective of this work was to assess the potential value of intra-operative hydrotubation in improving fertility of tubal infertile women. METHODS: 180 tubal infertile women were randomly assigned to one of the three groups: intra-operative hydrotubation (IH), post-operative hydrotubation (PH) or control group. In IH group, the hydrotubation was performed immediately after adhesiolysis during the surgery process, while in PH group it was performed within 3-7 days after the first post-operative menstruation. The incidence of post-operative pelvic infection and average hospitalization length were recorded. The post-operative pregnancy outcomes, including intrauterine pregnancy (IUP) rate and incidence of ectopic pregnancy, were recorded at 2 years follow-up. RESULTS: No significant difference was found among the three groups, either in the incidence of pelvic infection (P = 0.877) or in the average hospitalization length (P = 0.596). At 2 years of follow-up, the rate of IUP in IH group was significantly higher than that in either PH or control group (P = 0.017 and 0.039, respectively), but no difference was observed between PH and control group (P = 0.752). No significant difference in the incidence of ectopic pregnancy was showed among three groups (P = 0.947). CONCLUSIONS: The appropriate use of intra-operative hydrotubation can improve the post-operative IUP rate, serving as a complementary procedure for the surgical treatment of fertility reversal.
