Hansen and Spuhler [1] developed a more naturalistic, genetically heterogeneous rat stock with the aim of optimizing the distribution of genotypic frequencies and recombination and under the hypothesis that the NIH-HS stock could yield a broad-range distribution of responses (broader than commonly used laboratory rat strains) to experimental conditions, and thus serve as a base population for selection studies. Along the last decade, in a series of studies we have phenotypically characterized the NIH-HS rat stock (a colony exists at our laboratory since 2004) for their anxiety/fearfulness profiles (using a battery of both unconditioned and conditioned tests/tasks), as well as regarding their stress-induced hormonal responses, coping style under inescapable stress and spatial learning ability. We have also compared the phenotypic profiles of NIH-HS rats with those of the low anxious RHA-I and the high anxious RLA-I rat strains. The NIH-HS rat stock is, as a population, a rather anxious type of rat, with predominantly reactive/passive coping style in unlearned and learned anxiety/fear tests, and elevated stress hormone responses (as well as enhanced “depressive” symptoms in the forced swimming test). Genetic studies currently under way have thus far revealed that the genetically heterogeneous NIH-HS rat stock constitutes a unique tool for fine mapping of QTL (for multiple behavioural and biological complex traits) to megabase resolution levels, thus enabling candidate gene identification. We give some examples of this in the present paper, while also highlighting that microarray gene expression studies reveal that HPA-axis- and prolactin-related genes (among others) in the amygdala appear to be related with (or associated to) the coping style and anxiety/fearfulness responses of NIH-HS rats.展开更多

It has been reported that when fear-conditioned animals are put in a fear extinction paradigm with non-fearful conspecifics (pair-exposure), freezing behavior decreases compared to a solitary situation. However, it remains unclear whether pair-exposure during fear extinction is persistently effective in reducing the freezing response. In this study, we examined whether the effect of pair-exposure could be persistently effective on cued and contextual fear extinction. The reduction of the fear compared to the solitary condition was transiently observed only in the cued fear extinction with no difference in the subsequent recall session. We also found that the correlation between corticosterone levels and freezing behavior during extinction was disrupted in the pair-exposure situation. These results suggest that pair-exposure reduces freezing behavior in cued fear extinction, although this fear response reduction is not persistent. The pair-exposure changed an association between corticosterone levels and freezing behavior during extinction.展开更多

文摘Neuronal activity,synaptic transmission,and molecular changes in the basolateral amygdala play critical roles in fear memory.Cylindromatosis(CYLD)is a deubiquitinase that negatively regulates the nuclear factor kappa-B pathway.CYLD is well studied in non-neuronal cells,yet underinvestigated in the brain,where it is highly expressed.Emerging studies have shown involvement of CYLD in the remodeling of glutamatergic synapses,neuroinflammation,fear memory,and anxiety-and autism-like behaviors.However,the precise role of CYLD in glutamatergic neurons is largely unknown.Here,we first proposed involvement of CYLD in cued fear expression.We next constructed transgenic model mice with specific deletion of Cyld from glutamatergic neurons.Our results show that glutamatergic CYLD deficiency exaggerated the expression of cued fear in only male mice.Further,loss of CYLD in glutamatergic neurons resulted in enhanced neuronal activation,impaired excitatory synaptic transmission,and altered levels of glutamate receptors accompanied by over-activation of microglia in the basolateral amygdala of male mice.Altogether,our study suggests a critical role of glutamatergic CYLD in maintaining normal neuronal,synaptic,and microglial activation.This may contribute,at least in part,to cued fear expression.

文摘Post-traumatic stress disorder(PTSD)is a severe neuropsychiatric disorder characterised by reexperiencing,avoidance and hyperarousal.Memory abnormalities manifested as intrusive thoughts and prolonged distressful emotions are postulated as key roles in PTSD development and persistence.Over the past decades,convergent results from human and animal studies have systematically investigated contributions of the amygdala,hippocampus and medial prefrontal cortex(mPFC)in fear memory processes,including fear acquisition,storage,reconsolidation and extinction.These findings provide mechanistic insights for cognitive-behavioural therapy and aid in developing pathological region-targeted neuromodulation treatment for PTSD.Taking advantage of advances in cell-type selective labelling and manipulation technologies,recent studies have focused on the spatiotemporal regulation of neural circuits underlying distinct phases of fear memory processes.These findings have revealed that multiple distributed brain areas participate in the fear memory encoding network.Moreover,the functional role of distinct neuronal ensembles within the amygdala-hippocampus-mPFC pathway,identified by genetic markers and projection profiles,has been assigned to temporally separate features of fear processing,demonstrating the sophistication of the fear encoding circuit.These results provide mechanistic insights into PTSD pathology and might shed light on aetiology-based clinical interventions for PTSD.Therefore,the present review will mainly focus on the recent progress in elucidating neural circuit mechanisms underlying the dynamic regulation of fear memory,with an emphasis on the spatial distribution of fear memory encoding neural networks and the temporal coherence between neuronal ensemble activity and fear expression.
文摘Objectives:Childbirth fear affects 34.2%of Chinese primigravida women,leading to adverse birth outcomes.Family-centered prenatal education(FCPE)may reduce fear through enhanced support systems.Methods:This quasiexperimental study examined the effectiveness of FCPE among 120 primigravida women(14–20 weeks’gestation)at Yancheng Third People’s Hospital.Participants with elevated Childbirth Fear Questionnaire(CFQ)scores(≥81)were assigned to either the experimental group(FCPE+standard care,n=60)or the control group(standard care only,n=60).FCPE consisted of five weekly 2-hour sessions involving pregnant women and family members.Results:Both groups showed moderate baseline fear levels(experimental:85.68±6.30;control:88.57±6.41,p=0.112).Post-intervention,the experimental group achieved significantly lower fear scores(80.43±8.53 vs.87.35±6.91,p=0.001,Cohen’s d=0.88).58.3%of experimental participants transitioned to low fear levels,compared to 16.7%in the control group.Educational level significantly moderated the outcomes within the experimental group(p=0.031).Conclusion:FCPE effectively reduces anticipatory childbirth fear with a large effect size,supporting implementation in Chinese prenatal care for improving maternal psychological well-being.

文摘Objectives:This study aimed to explore the effectiveness and advantages of an“Internet+”nursing model based on user profilingin the rehabilitation of postoperative breast cancer patients.Methods:Breast cancer patients admitted to the hospital from July 2023 to September 2024 were enrolled.These patients were randomly assigned to a control group and an intervention group,with 52 patients in each group.The control group received routine nursing care,while the intervention group received an“Internet+”nursing intervention based on user profilingin addition to routine care.The intervention period lasted for one month following discharge.Before and one month after the intervention,the Fear of Progression Questionnaire-Short Form(FOP-Q-SF),the Fear of Cancer Recurrence Inventory-Short Form(FCRI-SF),Chinese Posttraumatic Growth Inventory(C-PTGI),and the Functional Assessment of Cancer Therapy-Breast(FACT-B)were applied to assess the effects of interventions.Results:A total of 104 patients were analyzed.After the intervention,FOP-Q-SF and FCRI-SF scores were significantlylower in the intervention group compared to the control group,with statistical significance(t=3.98,P<0.001;t=-7.59,P<0.001),and Cohen’s d of 0.781 and 1.49,respectively.Additionally,CPTGI and FACT-B scores in the intervention group were significantly higher than those in the control group(t=-6.534,P<0.001;t=-4.579,P<0.001),with Cohen’s d of 0.585 and 0.656.Conclusions:An“Internet+”nursing model based on user profilingcould reduce postoperative breast cancer patients fear of disease progression and cancer recurrence,also enhancing posttraumatic growth and overall quality of life.
文摘BACKGROUND Fear of childbirth(FoC)is a widespread issue that impacts the health and well-being of mothers and newborns.However,there is inconsistency regarding the prevalence of FoC in the and there is limited research on the prevalence of FoC among Australian pregnant women.AIM To investigate the prevalence of FoC,its risk factors and birth outcomes in Aust-ralian multiparous women.METHODS In this prospective cohort quantitative study,212 multiparous women were re-cruited from antenatal clinics at Westmead Hospital in western Sydney from 2019 to 2022.Pregnant women who attended antenatal visits and met the inclusion criteria signed the consent forms and completed several online questionnaires at baseline.After they gave birth,their birth outcomes were collected from the hospital’s medical record database.The data were analyzed using SPSS software and descriptive statistics,χ^(2)test,independent samples t-test,and multivariable logistic regression analysis.RESULTS Out of 212 participants,24%experienced a high level of FoC and 7%experienced severe FoC.Theχ^(2)test results revealed that a family income of≤$100000,no alcohol intake during pregnancy,pre-existing health problems,previous caesarean section(emergency or planned),and previous neutral/traumatic childbirth experiences were significantly associated with higher levels of FoC(P<0.05).Other risk factors included being moderately to very worried and fearful about the upcoming birth,having severe to extremely severe anxiety throughout pregnancy,and expressing low relationship satisfaction.According to multivariable logistic regression,the odds of a high level of FoC were higher in women with anxiety,a history of traumatic childbirth experience,a history of sexual assault during childhood,pre-existing health problems,and lower relationship satisfaction(P<0.05).CONCLUSION High-severe levels of FoC are experienced by pregnant multiparous women and are affected by several demo-graphic factors.However,due to the small sample size in the present study,further studies with larger sample sizes are required to draw a firm conclusion on the prevalence of severe FoC among multiparous women and its associated risk factors and birth outcomes.

文摘Post-traumatic stress disorder(PTSD)is a psychiatric disorder caused by traumatic past experiences,rooted in the neurocircuits of fear memory formation.Memory processes include encoding,storing,and recalling to forgetting,suggesting the potential to erase fear memories through timely interventions.Conventional strategies such as medications or electroconvulsive therapy often fail to provide permanent relief and come with significant side-effects.This review explores how fear memory may be erased,particularly focusing on the mnemonic phases of reconsolidation and extinction.Reconsolidation strengthens memory,while extinction weakens it.Interfering with memory reconsolidation could diminish the fear response.Alternatively,the extinction of acquired memory could reduce the fear memory response.This review summarizes experimental animal models of PTSD,examines the nature and epidemiology of reconsolidation to extinction,and discusses current behavioral therapy aimed at transforming fear memories to treat PTSD.In sum,understanding how fear memory updates holds significant promise for PTSD treatment.
文摘BACKGROUND Cervical cancer,a prevalent gynecological malignancy,exhibits recurrence rates of 30%-50%post-treatment,with recurrent cases facing a dire 10%-20%long-term survival rate,severely impacting patients’mental health and quality of life.Fear of cancer recurrence(FCR)emerges as a critical psychological challenge,often leading to anxiety,social avoidance,and even suicidal tendencies.Despite its high prevalence,structured,evidence-based interventions for FCR in cervical cancer remain scarce,with most studies focusing on general psychological support rather than targeted strategies.The fear of progression theory provides a theoretical framework,highlighting cognitive-emotional conflicts arising from perceived threats of disease recurrence.Addressing this gap,this study developed a specialized,phased psychological intervention program grounded in fear of progression theory,aiming to reduce FCR and enhance resilience in cervical cancer survivors through multi-disciplinary strategies.AIM To establish a psychological intervention program to support the fear of cervical cancer recurrence and to alleviate the psychological pressure of patients after cervical cancer surgery.METHODS Thirteen experts were selected to conduct two rounds of correspondence through literature review and group discussions to amend the psychological intervention draft and form the basis for the psychological intervention.The selected experts also performed two rounds of correspondence to revise the psychological intervention draft and outline the first draft,and pre-experiments were conducted for further improvement of the psychological intervention program.Experiments were performed in 80 patients with cervical cancer to further improve the psychological intervention program of relapse fear support.RESULTS The expert authority coefficient of the first and second rounds was higher than 0.8,indicating high authority.The coordination coefficient>0.8 indicated high consistency with high significance(all P<0.05).The FCR Inventory,Kessler Psychological Distress Scale,Psychological Distress Thermometer,and General Hospital Anxiety and Depression Scale scores at 3 and 6 months in the study group were lower than those of the control group,and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 and Perceived Social Support Scale scores were higher than those of the control group(P<0.05).CONCLUSION The psychological intervention program of relapse fear support which considers the individual differences between patients and expert opinions,has a good scientific and practical basis,and can be used to enhance the quality of life of patients.
文摘The present study explores the importance of developing metaphorical thinking skills in students within the framework of English as a Foreign Language(EFL)reading courses at the tertiary educational level.Metaphorical thinking is viewed as the ability to envisage the world figuratively,perceive associatively,and express oneself creatively.It is crucial to recognize metaphors in texts,interpret the complex images they evoke,and generate new metaphors.It is especially needful in the current era of clip thinking and fragmented information processing when students often approach content superficially rather than comprehensively,leading to decreased cognitive activity and a diminished capacity to understand literature.To foster metaphorical thinking,the paper suggests building a text associative-semantic field focusing on metaphors.Due to its hierarchical structure,which can be envisioned as a dense nucleus surrounded by a central region of synonyms and further enveloped by a periphery of more loosely associated linguistic units,the text associative-semantic field is seen as a potent solution for facilitating improved visualization and more holistic comprehension of information,allowing students for expanding their vocabulary and strengthening associative connections.Notably,the study highlights analyzing the metaphors of emotional states as they contribute significantly to a more profound interpretation of the text,understanding the writer’s unique style,deepening the students’engagement with the book,and expanding their emotional experiences.

文摘In the contemporary research landscape of mental illness treatment,fear-related disorders such as post-traumatic stress disorder continue to pose significant challenges.Although exposure therapy remains a fundamental component of treatment,its efficacy varies considerably among individuals.DNA methylation plays a pivotal role in the extinction of fear memories,providing a promising molecular mechanism that could enhance the success of exposure-based interventions.Extensive studies have consistently demonstrated a substantial association between DNA methylation and neuronal plasticity.While DNA methylation holds potential regulatory effects on the effectiveness of exposure therapy,the bidirectional regulatory relationship between it and neuronal activity necessitates addressing several challenges before its widespread clinical application for mental disorders.First,excessive DNA methylation may suppress neural function,and non-selective enhancement of methylation could be counterproductive.Furthermore,due to potential systemic side effects,the use of methylation-modulating agents might disrupt the physiological balance and functionality of other organs and systems.Despite the dynamic interplay between DNA methylation and neuronal activity offering novel insights into the treatment of mental disorders, the strict consideration of target specificity and an appropriate dosing window requirescautious implementation in clinical practice.

文摘The nonlinearity and fear hypothesis predicts that highly aroused vocal mammals and birds produce vocalizations(notably alarm calls and screams)which contain a variety of nonlinear phenomena(NLP).Such vocalizations often sound“noisy”because vocal production systems are over-blown when animals are highly aroused.While much is known about the conditions under which animals produce vocalizations containing NLP and how species respond to them,there is little research about the heritability of such behavioral traits.Using the quantitative genetic animal model,we estimated the genetic basis of“noise”in alarm calls produced by females and found significant heritability in call entropy-our measure of the noisiness.About 9%of the variance in noisiness can be accounted for by genetic differences.Taken together,these findings suggest that the degree to which marmots produce noisy calls is modestly heritable and can be thus subject to further evolution via natural selection.
