Background: Previous studies suggested that childhood trauma is an important etiologic factor for the development of borderline personality disorder (BPD). Moreover, insecure attachment and maladaptive emotion regulation (ER) might be related to childhood trauma and BPD. This study was aimed to explore the relationships among childhood trauma, insecure attachment, maladaptive ER, and BPD features. Methods: A cohort of 637 patients with psychological disorders completed a series of psychometric instruments such as the Personality Diagnostic Questionnaire-4+ (PDQ-4+), the 23-Item Borderline Symptom List, the Childhood Trauma Questionnaire, the Attachment Style Questionnaire, and the Cognitive Emotion Regulation Questionnaire. The path analyses were conducted to investigate the experience-driven model that whether insecure attachment and maladaptive ER could mediate the relationship between childhood trauma and BPD features. The random forest regression was performed to select variables that contribute significantly to BPD features, which variables would be incorporated into the datadriven model to further confirm the experience-driven model. Results: Both the experience-driven model and the data-driven model verified that there were three significant mediation pathways (childhood trauma → insecure attachment/maladaptive ER → BPD features, childhood trauma → insecure attachment → maladaptive ER → BPD features; all p < .05), and the most weighted mediation pathway by which childhood trauma influencing the BPD features was through insecure attachment and then through maladaptive ER (weighted 53.16%). Conclusion: The influence of childhood trauma on BPD features was mainly mediated by the combination of insecure attachment and maladaptive emotion regulation.

The acute non-image forming (NIF) effects of daytime light on momentary mood had been-although not always-established in the current literature. It still remains largely unknown whether short-time light exposure would modulate emotion perception in healthy adults. The current study (N = 48) was conducted to explore the effects of illuminance (100 lx vs. 1000 lx at eye level) and correlated color temperature (CCT, 2700 K vs. 6500 K) on explicit and implicit emotion perception that was assessed with emotional face judgment task and emotional oddball task respectively. Results showed that lower CCT significantly decreased negative response bias in the face judgment task, with labeling ambiguous faces less fearful under 2700 K vs. 6500 K condition. Moreover, participants responded slightly faster for emotional pictures under 6500 K vs. 2700 K condition, but no significant effect of illuminance or CCT on negativity bias was revealed in the emotional oddball task. These findings highlighted the differential role of illuminance and CCT in regulating instant emotion perception and suggested a task-dependent moderation of light spectrum on negativity bias.

BackgroundEmerging evidences supported the hypothesis that emotional dysregulation results from aberrant connectivity within the fronto-limbic neural networks in patients with borderline personality disorder (BPD). Considering its important role in emotional regulation, the anterior cingulate cortex (ACC) has not yet been fully explored in BPD patients. Therefore, using the seed-based resting state functional connectivity (rsFC) and probabilistic fiber tracking, we aimed to explore the alterations of functional and structural connectivity (SC) of the ACC in patients with BPD.MethodsA cohort of 50 unmedicated, young BPD patients and 54 sex-, age-, and education-matched healthy controls (HCs) completed psychological tests and underwent rs-fMRI and diffuse tensor imaging (DTI) scanning. Rs-FC analysis and probabilistic fiber tracking were used to plot SC and FC of the ACC.ResultsWith the left ACC selected as a seed, BPD patients exhibited increased rsFC and abnormal SC with the right middle frontal gyrus (MFG), and decreased rsFC with the left middle temporal gyrus (MTG), compared with HCs. Additionally, negative cognitive emotion regulation and depressive symptoms both correlated negatively with the rsFC of the left ACC in BPD patients.ConclusionAbnormal SC and FC of the ACC underlie the deficient emotional regulation circuitry in BPD patients. Such alterations may be important biomarkers of BPD and thus could point to potential BPD treatment targets.

We demonstrate an effective method for realization of robust, tailorable annular plasma photonic crystals in dielectric barrier discharge (DBD) with two water electrodes. Fast reconfiguration between triangular lattice, annular lattice, core-annular lattice and concentric-annular lattice has been achieved. An active control on the structure of plasma elements is realized by solely changing the applied voltage. The changes of photonic band gaps with reconfiguration of different annular plasma photonic crystals have been studied both experimentally and numerically. The band gaps between 28.0-30.0 GHz for the core-annular lattice and the concentric-annular lattice are experimentally verified. A phenomenological reaction-diffusion model with two nonlinear-coupled interacting layers is established to mimic the formation of various plasma structures. Experimental observations and numerical simulation are in good agreement. Our approach provides a unique strategy to create reversibly deformable annular plasma photonic crystals, which may offer new capabilities and serve as a promising platform for various applications.
