Efficacy of cognitive behavioral therapy for middle school student's unprotected sex: A randomized controlled trial / 中国心理卫生杂志

Objective:To evaluate the efficacy of individualized cognitive behavioral therapy for unprotected sex and sexual attitude of middle school students having unprotected sex.Methods:A target sample of 68 adolescents having unprotected sex was recruited from 4 secondary schools in Changsha,Hunan [the unprotected sex (US) score of Health-Risk Behavior Inventory for Chinese Adolescents (HBICA) ≥ 1].Subjects were randomized assigned to cognitive behavioral therapy group (CBT group) and control group.Each group had 34 subjects.The CBT group was giving one-on-one counseling for 6 weeks (50 to 60 minutes weekly).The control group didn't receive intervention by counselors.The US and Attitudes Toward Sexuality Scale (ATSS) were selected as criterion measurements.Outcome assessments were made at baseline and at 1-and 3-month follow-up.Results:The reduction rate of US scores showed that the response rate of therapy was over 80％.Mixed linear model analysis showed that there were significant group effect,time effect and group × time effect in scores of US and ATSS (Ps ＜ 0.05).Simple effect analysis indicated that the scores of US and ATSS of CBT group were significant lower than those of baseline from 1-month follow-up [(2.2 ± 2.9) vs.(4.7 ± 3.1),(3.2 ± 1.6) vs.(4.7 ± 3.1);(38.2 ± 4.9) vs.(40.9 ±5.1),(37.2 ±5.4) vs.(40.9 ±5.1),Ps ＜0.01],whereas the scores of those in the control group did not show any significant difference (Ps ＞0.05).At l-month and 3 month follow-up,moderate effect sizes were found for the CBT and control groups on all the outcome measures (Cohen's d =0.50-0.70).Conclusion:The individualized cognitive behavioral therapy could effectively reduce the level of unprotected sex and sexual attitude of adolescents having unprotected sex.

Effects of maternal deprivation on stress response and efficacy of escitalopram in adult rats / 中华行为医学与脑科学杂志

Objective To investigate the effects of maternal deprivation on chronic stress?induced depression behavior and its characteristics in adult rats,and to evaluate the effects of maternal deprivation on the efficacy of escitalopram. Methods Newborn SD male rats were randomly divided into control ( C ) group,maternal deprivation (MD) group,chronic unpredictable stress (CUPS) group,maternal deprivation and chronic unpredictable stress ( MD+CUPS) group. Rats in control group received no experimental han?dling.Rats in MD group and MD+CUPS group received maternal deprivation from the lst day after birth for 14 days.Rats in CUPS group and MD+CUPS group received chronic unpredictable stress from 10 th weeks after birth for 28 days. Screened the rats with depression behaviors and treated them with escitalopram for 4 weeks. Results The incidence of anhedonia was significantly different among 4 groups (χ2=143.24, PCUPS group (40.98%) > MD group (17.11%) >C group (4.17%), P<0.0083). The incidence of behav?ioral despair was significantly different among 4 groups (χ2=70.34, P<0.05). Pairwise comparison showed the incidence of behavioral despair in MD+CUPS group (43.43%) and CUPS group (39.34%) were signifi?cantly higher than that in MD group (13.51%) and C group (3.33%),but no difference was observed be?tween MD+CUPS and CUPS group (P<0.0083) . The incidence of behavioral despair in MD group was signif?icant higher than that in C group. There was no significant efficacy of escitalopram on anhedonia and behav?ioral despair among 3 stressed models. However the recovery incidence from anhedonia (44/140) was significantly lower than that from behavioral despair (76/140) (χ2=14.93, P<0.05). Conclusion The maternal deprivation in?creases the stress sensitivity and the incidences of anhedonia in adult rats.The efficacy of escitalopram on behavioral despair is higher than that on anhedonia without influence from maternal deprivation.

Event-related potentials of non-mediated obsessive-compulsive disorder patients in an emotional Stroop task / 中华行为医学与脑科学杂志

Objective To study the difference of attentional bias towards general negative words between non-mediated obsessive-compulsive disorder (OCD) patients and healthy controls.Methods Event-related potentials (ERPs) were collected from 26 non-mediated OCD patients and 24 normal controls while they performed an emotional Stroop task.Results Compared to healthy controls,OCD patients showed significantly longer reaction time (OCD:(467 ± 14.88) ms,Controls:(409.65 ± 15.49) ms,P＜ 0.01),and had significantly larger P2 and P3 amplitude to all three types of words (P2 amplitude:OCD:(10.41±0.49) μV,Controls:(8.89±0.48) μV,P＜0.05;P3 amplitude:(10.04±0.68) μV,Controls:(7.68±0.67) μV,P＜0.05).In addition,the P2 peak latency of the frontal area in OCD patients was significantly longer than that in healthy controls(OCD:(190.09±4.71) ms,Controls:(179.60±4.72) ms,P＜0.05).Conclusion Current findings suggest that OCD patients are characterized by a general attentional inhibition deficit but not an attentional bias to the negative words.

The dysregulation of hippocampal serotonin receptor 4 and let-7a were associated with dual stress-induced depression in rats / 中华行为医学与脑科学杂志

Objective To study the effect of dual stress on the behaviors and the expression of hippocampal let-7a and serotonin receptor 4(HTR4) in rats.Methods Newborn SD rats were randomly divided into dual stress group (DS,n=6) and control group (C,n=6).The DS rats were deprived of the mother care 6 hours per day from postnatal day 1 to 14 and then were exposed to chronic mild stress for 21 days from 10 weeks old,while the rats from C group received no experimental handle but husbandry care.Open field test,forced swimmiug test and sucrose consumption test were conducted to evaluate rats' depression-like behaviors at the age of thirteen weeks.The let-7a level in hippocampus was detected by real-time Polymerase Chain Reaction and the HTR4 protein level was measured by Western Blotting.Results In the open filed test,the rearing times of DS rats was shorter than that of C group((7.50±2.35) vs (19.00±5.73),P＜0.05).In the forced swimming test,the floating time of DS rats was longer than that of C group ((110.17 ± 1.72)s vs (70.33± 1.16)s,P＜ 0.05).In the sucrose c onsumption test,DS rats consumed less sucrose than rats from C group did((0.80±0.73) vs (0.52±0.26),P＜ 0.05).The protein level of hippocampal HTR-4 in DS group was lower than that of C group((1.44±0.38) vs (0.46±0.29),P＜0.01).The let-7a level in DS group was higher than that of C group((0.04±0.01) vs (1.58±0.27),P＜0.01).The Pearson correlation analysis revealed that the sucrose preference rate of rats were negatively and positively correlated with hippocampal let-7a and HTR4 level respectively(r=-0.653,P＜0.05; r=0.774,P＜0.01),and hippocampal let-7a level showed negative association with HTR4 protein level (r=-0.803,P＜0.01).Conclusion Dual stress can induce the depressive behaviors of rats and affect the expression of let-7a and HTR4 in hippocampus.Hippocampal HTR4 and let-7a might be involved in determining individual ability to experience pleasure in rats;and hippocampal let-7a may be involved in the regulation of HTR4 gene expression in rats.

Expression of miR-16 in the hippocampus of depressed adult rats induced by maternal deprivation / 中南大学学报(医学版)

OBJECTIVE@#To detect the expression of miR-16 in the hippocampus of a rat depression model induced by maternal deprivation, and to explore whether miR-16 is involved in the pathological process of maternal deprivation-induced depression.@*METHODS@#Newborn SD rats were randomly divided into a maternal deprivation group (n=17) and a control group (n=17). Rats in the maternal deprivation group experienced maternal deprivation for 6 h per day from 1st to 14th postnatal day, while rats in the control group rats received no treatment. When the rats were 13 weeks old, depression-like behaviors were assessed by forced swimming test and sucrose consumption test, and the expression of hippocampal miR-16 in rats was detected by real-time RT-PCR.@*RESULTS@#Maternal-deprived rats exhibited significantly longer passive floating time and lower sucrose preference rate than rats in the control group (P<0.05). Maternal-deprivation rats expressed higher level of miR-16 in the hippocampus than rats in the control group, and the expression level of miR-16 was significantly associated with the passive floating time (r=0.65, P<0.05) and the sucrose preference rate (r=-0.59, P<0.05).@*CONCLUSION@#Maternal deprivation can induce depressive behaviors in rats and increase the expression of miR-16 in the hippocampus in rats. MiR-16 may be involved in the pathological mechanism of the maternal deprivation-induced depression.

The difference among the depression-like behaviours induced by three widely-used stress models in rats / 中华行为医学与脑科学杂志

Objective In order to study the difference of depression-like behaviours among three widelyused stress models in rats.Methods The new-born Spragne-Dawley rats were randomly divided into maternal deprivation(MD) group(n=27),chronic mild stress(CMS) group (n=29),dual stress(DS) group ( n=31 ) and control (C) group ( n =30) on postnatal day 1.MD rats only received maternal deprivation.CMS rats only received chronic mild stress when 10 weeks old.DS rats received both maternal deprivation and chronic mild stress.Control rats received no experimental handling.Behavior tests including forced swimming test and sucrose consumption which were carried out to evaluate rats' depression-like behaviors in the thirteenth weeks.The extend time of floating and sucrose preference ratio should be recorded in the forced swimming test and sucrose consumption test respectively to reflect the behavior of helplessness and anhedonia of rats.Results In the forced swimming test,the extend floating time of MD group( 119.30 ± 65.56) s,CMS group ( 145.00 ± 80.24) s and DS group ( 170.03 ±61.75 )s were longer than the control group(81.14 ± 52.40)s (F =11.53,P ＜ 0.01 ).In the sucrose consumption test,the MD group(0.32 ± 0.22) had a low sucrose consumption.The comparison of the MD group and CMS group (0.43 ± 0.28 ) to the control group (0.54 ± 0.28 ) had significant differences (F =4.33,P ＜ 0.01 ).In these four groups,no sexual difference was found in the forced swimming test and sucrose consumption test ( all P ＞ 0.05 ).Conclusion The results suggest that MD,CMS and DS may induce some kind of depression-like behaviors in rodents such as anhedonia or the behavior of helplessness and the depression-like behaviors induced by different stresses are similar in male and female individuals.

Cognitive Emotion Regulation Questionnaire in hypertensive patients / 中南大学学报(医学版)

Objective To examine the reliability,validity,and practicability of Cognitive Emotion Regulation Questionnaire (CERQ) in hypertensive patients in China.Methods Altogether 434 hypertensive patients and 462 healthy subjects were recruited. All the subjects were assessed with the CERQ-Chinese version (CERQ-C), Dysfunctional Attitude Scale (DAS), Mood and Anxiety Symptom Questionnaire-Short Form (MASQ-SF), and Center for Epidemiologic Studies Depression Scale (CES-D). We calculated the mean inter-item correlations for the total CERQ and for each of the subscales. Cronbach's alpha coefficient was used to analyze the inter-correlation and reliability, and confirmatory factor analysis was used to examine the 9-factor model. Results 1) Hypertension group reported significantly higher score than that of healthy ones on rumination (12.19±2.51 vs. 11.51±2.60, P<0.001), catastrophizing(8.82±2.19 vs.8.11±2.70,P<0.001),and blaming others(10.76±2.11 vs. 9.88±2.48,P<0.001), and had significantly lower score than that of healthy ones on positive reappraisal(13.80±3.55 vs.14.71±4.11,P<0.001).2)Reliability:In the hypertension group the Cronbach's alpha for the total CERQ was 0.80, and that for the 9 subscales ranged from 0.71 (self-blame) to 0.90 (rumination). In the healthy group the Cronbach's alpha for the total CERQ was 0.79, and that for the 9 subscales ranged from 0.71 (positive reappraisal) to 0.90 (rumination). The mean inter-item correlation coefficient for the 9 subscales was 0.21-0.42(the hypertension group)/0.19-0.32 (the healthy group). In the hypertension group,the test-retest reliability of the total scale was 0.82, the test-retest reliability of the 9 subscales ranged from 0.73 to 0.92. The confirmatory factor analysis showed that the 9 first-order factor data fitted both 2 samples well. Conclusion CERQ meets the psychometric standard and it is reliable and valid for cognitive emotion regulation strategies, which may be regarded as an appropriate assessment tool.

Effect of maternal deprivation on emotion and expression of dopamine transporter in adult rats / 中南大学学报(医学版)

Objective To investigate the change of emotion and striatum dopamine transporter(DAT) expression in adult male rats experiencing maternal deprivation, and to explore whether DNA methylation is involved in the regulatory mechanism of DAT expression. Methods Newborn rats were randomly divided into 2 groups: a maternal separation group (n=16) and a control group (n=14). The maternal deprivation group were separated from their mother for 6 hours (09∶00-15∶00) per day from postnatal day 1 to 14, while the controls (n=14) without the deprivation. When the rats in the 2 groups were 12 week, their spontaneous anxiety levels and exploratory ability in novel environments were assessed by an elevated plus maze and an open field test. DAT mRNA expression in the striatum was detected by reverse transcription-PCR, and its DNA methylation level was measured by bisulfated DNA sequencing. Results Maternally-deprived rats showed lower ability of exploring in a new environment and lower levels of anxiety than the controls. The expression of DAT mRNA in the striatum of the maternal separation group (0.236±0.043) was significantly lower than that in the control group (0.480±0.107) (P＜0.05). However the DNA methylation level in the promoter region of DAT was not significantly different between the 2 groups. Conclusion Maternal deprivation influenced the emotion and expression of dopamine transporter in adult rats and DNA methylation may not be involved.

Effect of antidepressant and psychological intervention on the quality of life and blood pressure in hypertensive patients with depression / 中南大学学报(医学版)

OBJECTIVE@#To investigate the effect of antidepressant and psychological intervention on the blood pressure and quality of life in hypertensive patients with depression.@*METHODS@#After evaluating 950 patients with essential hypertension by Hospital Anxiety and Depression Scale (HAD), patients with HAD positive results were evaluated with Hamilton Depression Scale (HAMD) and Hamilton Anxiety Scale (HAMA). The positive subjects with HAMD were randomly divided into an antidepressant and psychological intervention group (n=30, including routine treatment, mental state intervention, and antidepressant treatment) and a control group (n=30, routine treatment alone). The blood pressure, quality of life, and level of depression were compared between the 2 groups.@*RESULTS@#The depression symptoms were significantly improved in the antidepressant and psychological intervention group. The HAMD score fell from 30.03+/-1.83 at entrance to 17.43+/-1.96 at the end of study. The blood pressure control was more effective in the antidepressant and psychological intervention group than in the control group. The mean systolic blood pressure (SBP) and diastolic blood pressure (DBP) decreased by 26.17 mmHg and 13.63 mmHg in the antidepressant and psychological intervention group, while there were only 14.32 mmHg and 7.18 mmHg decrease in SBP and DBP respectively in the control group. Patients in the antidepressant and psychological intervention group had a higher score in the quality of life. The total score of GQOLI-74 increased from 65.97+/-4.68 before the treatment to 71.20+/-5.13 after the treatment.@*CONCLUSION@#Psychological intervention and antidepressant can improve the blood pressure control and quality of life in hypertensive patients with depression.
