摘要：
Depression has been identified as a risk factor for suicide, yet limited evidence has elucidated the underlying pathways linking depression to subsequent suicide risk. Therefore, we aimed to examine the psychological mechanisms that connect depression to suicide risk via linguistic characteristics on Weibo. We sampled 487,251 posts from 3196 users who belong to the depression super-topic community (DSTC) on Sina Weibo as the depression group, and 357,939 posts from 5167 active users as the control group. We employed the double machine learning method (DML) to estimate the impact of depression on suicide risk, and interpreted the pathways from depression to suicide risk using SHapley Additive exPlanations (SHAP) values and tree in-terpreters. The results indicated an 18% higher likelihood of suicide risk in the depression group compared to people without depression. The SHAP values further revealed that Exclusive (M = 0.029) was the most critical linguistic feature. Meanwhile, the three-depth tree interpreter illustrated that the high suicide risk subgroup of the depression group (N = 1196, CATE = 0.32 +/- 0.04, 95%CI [0.20, 0.43]) was predicted by higher usage of Exclusive (>0.59) and Health (>-0.10). DML revealed pathways linking depression to suicide risk. The visualized tree interpreter showed cognitive complexity and physical distress might be positively associated with suicide risk in depressed populations. These findings have invigorated further investigation to elucidate the relationship between depression and suicide risk. Understanding the underlying mechanisms serves as a basis for future research on suicide prevention and treatment for individuals with depression.
摘要：
The HIV-1 transactivator protein Tat interacts with the transactivation response element (TAR) at the three-nucleotide UCU bulge to facilitate the recruitment of transcription elongation factor-b (P-TEFb) and induce the transcription of the integrated proviral genome. Therefore, the Tat-TAR interaction, unique to the virus, is a promising target for developing antiviral therapeutics. Currently, there are no FDA-approved drugs against HIV-1 transcription, suggesting the need to develop novel inhibitors that specifically target HIV-1 transcription. We have identified potential candidates that effectively inhibit viral transcription in myeloid and T cells without apparent toxicity. Among these candidates, two molecules showed inhibition of viral protein expression. A molecular docking and simulation approach was used to determine the binding dynamics of these small molecules on TAR RNA in the presence of the P-TEFb complex, which was further validated by a biotinylated RNA pulldown assay. Furthermore, we examined the effect of these molecules on transcription factors, including the SWI/SNF complex (BAF or PBAF), which plays an important role in chromatin remodeling near the transcription start site and hence regulates virus transcription. The top candidates showed significant viral transcription inhibition in primary cells infected with HIV-1 (98.6). Collectively, our study identified potential transcription inhibitors that can potentially complement existing cART drugs to address the current therapeutic gap in current regimens. Additionally, shifting of the TAR RNA loop towards Cyclin T1 upon molecule binding during molecular simulation studies suggested that targeting the TAR loop and Tat-binding UCU bulge together should be an essential feature of TAR-binding molecules/inhibitors to achieve complete viral transcription inhibition.

摘要：
Early research has revealed distinct subgroups of cyberbullying victims. However, due to the limitations of traditional statistical methods, the characterization of features in the subgroups has been relatively limited, making it challenging to gain a relatively comprehensive understanding of different subgroup members. Decision trees and machine learning techniques offer notable advantages in addressing such issues. The primary aim of this study is to develop a high-performing classifier based on self-reported data from 814 middle school students to accurately predict cyberbullying victimization and uncover the most influential factors. On this basis, the study attempts to identify different subgroups of cyberbullying victims and their shared characteristics. The results indicated that the classification tree achieved a prediction accuracy of approximately 80% on the out-of-sample dataset. The results of permutation feature importance highlighted that the most prominent predictors were the victim’s cyberbullying perpetration, followed by traditional relational victimization and depression. Further examination of the visual tree structure revealed subgroups of cyberbullying victims and their shared characteristics. The findings of this study have enriched the characteristics of different subgroups of cyberbullying victims, providing a better elucidation of the pathology of cyberbullying victimization and offering empirical evidence to facilitate the development of more targeted intervention strategies for various subgroups of cyberbullying victims.

摘要：
ObjectivesMindful self-care is a way of embodied self-regulation that can safeguard and enhance psychological well-being. This study aimed to test the reliability and validity of the Chinese version of the Mindful Self-Care Scale (MSCS) among college students.MethodA total of 1486 college students (Mage = 19.36, SD = 1.16) from four different universities participated in this study. All participants completed a series of online surveys, including the MSCS, the Self-Compassion Scale-Short Form, the Body Appreciation Scale-2, and the Satisfaction With Life Scale. Confirmatory factor analysis was used to evaluate the validity of the MSCS, and the R package measureQ was utilized to calculate the reliability. Additionally, we conducted comparative analyses involving the MSCS (33 items), its brief version (Brief-MSCS, 24 items), and previous relevant research.ResultsThe MSCS and Brief-MSCS demonstrated an acceptable factor structure, while the Brief-MSCS exhibited a more robust structure. Notably, the bifactor model adequately fitted the data for both versions. In bifactor model, each item not only belonged to its own group of factors but also belonged to a general factor. Both versions displayed satisfactory convergent validity, discriminant validity, concurrent validity, and robust composite reliability. Furthermore, Chinese college students exhibited a higher level of mindful self-care than Chinese medical professionals and a Western community sample.ConclusionsThe MSCS and Brief-MSCS have been found to be reliable and valid tools for assessing the levels of mindful self-care among college students, with the brief version showing superior performance. The robust fit of the bifactor model suggests that there is an overarching structure of mindful self-care that can be used to assess an individual's level through the total score. Moreover, there are differences in the level of mindful self-care among different groups, which need further verification.PreregistrationThis study is not preregistered.
摘要：
Cyberbullying and cyber victimization are widespread problems that impair the physical and mental health of adolescents. To date, the impact of parental phubbing on adolescent cyberbullying and cyber victimization remains underexplored. The current study investigates the relationships between parental phubbing and adolescent cyberbullying and cyber victimization and whether these influence mechanisms work consistently. We recruited 1034 Chinese adolescents aged 12–15 years as a sample and constructed two moderated mediation models to evaluate the relationships among parental phubbing, social anxiety, self-control, cyberbullying, and cyber victimization. The results showed that (1) parental phubbing positively predicted adolescent cyberbullying and cyber victimization; (2) parental phubbing was associated with cyberbullying and cyber victimization among adolescents through the mediating effect of social anxiety; (3) the relationships between parental phubbing and adolescent cyberbullying and cyber victimization and the mediating effects of social anxiety were moderated by self-control; specifically all effects were significant at low self-control and vice versa. The research findings are conducive to informing the risk factors and mechanisms of adolescent cyber violence and further reveal the negative influence of parental phubbing on adolescent development.

摘要：
Anxiety is a common psychological disorder associated with other mental disorders, with depression being the most common comorbidity. Few studies have examined the neural mechanisms underlying anxiety after controlling for depression. This study aimed to explore whether there are differences in cortical activation in anxiety patients with different severities whose depression are normal. In the current study, depression levels were normal for 366 subjects-139 healthy subjects, 117 with mild anxiety, and 110 with major anxiety. Using the Hospital Anxiety and Depression Scale (HADS) and a verbal fluency task (VFT) to test subjects' anxiety and depression and cognitive function, respectively. A 53-channel guided near-infrared spectroscopic imaging technology (fNIRS) detected the concentration of oxyhemoglobin (oxy-Hb). Correlation analysis between anxiety severity and oxy-Hb concentration in the brain cortex was performed, as well as ANOVA analysis of oxy-Hb concentration among the three anxiety severity groups. The results showed that anxiety severity was significantly and negatively correlated with oxy-Hb concentrations in the left frontal eye field (lFEF) and in the right dorsolateral prefrontal area (rDLPFC). The oxy-Hb concentration in the lFEF and the rDLPFC were significantly lower in the major anxiety disorder group than that in the control group. This suggests that decreased cortical activity of the lFEF and rDLPFC may be neural markers of anxiety symptoms after controlling for depression. Anxiety symptoms without depression may be result from the dysfunction of the cognitive control network (CCN) which includes the lFEF and rDLPFC.

social anxiety;social relationships;longitudinal studies;meta-analysis
摘要：
It is theoretically plausible that social anxiety (SA) and social relationships (SR) can influence each other. However, the available empirical evidence is inconsistent, leading to substantial uncertainty regarding the cross-lagged relations between SA and SR. This meta-analysis systematically integrates data from 107 longitudinal studies, comprising 110 independent samples and involving a total of 115,133 participants from childhood to adulthood. Four types of SR were assessed: family-related, school-related, romantic, and general relationships. One-stage meta-analytic structural equation modeling was applied to fit four cross-lagged panel models and to test potential moderators. No significant publication bias was detected. Effect size analyses revealed that prior SA significantly and negatively predicted quality of all types of SR. Family-related and general relationships each predicted prospective SA symptoms, but school-related and romantic relationships did not. No moderators were identified in analyses of family-related and romantic relationships. However, the publication year, sample age, gender, reporter, and time lag played a moderating role in analyses of school-related and general relationships. These findings suggest that SA is a crucial factor undermining SR and that dysfunctional family and general relationships also contribute to the exacerbation of SA symptoms. The strengths, limitations, and future directions of this study are discussed. Public Significance Statement A hotly debated issue in academia is whether past social anxiety (SA) hinders future social relationships(SR) or if prior poor SR precipitate subsequent SA symptoms. To shed light on this matter, a comprehensive meta-analysis was conducted, encompassing data from 107 longitudinal studies and involving over 110,000 participants. The findings suggest that SA poses a significant risk to all types of SR, but only family-related and general relationships potentially impacted later levels of SA.

Social network sites use;Depression;Self-esteem;Self-compassion;Children
摘要：
Previous research has conducted extensive work on the impact of social network site (SNS) use on depression. However, most of these studies have focused on adolescents or adults, and little is known about how SNS use affects depression among children. Based on the vulnerability model of depression, the self-system beliefs model, and the risk-buffering hypothesis, we examined whether self-esteem would mediate the relationship between SNS use and children's depression and whether self-compassion would play a moderating role in the mediating process. The sample consisted of 386 Chinese children from grades three to six (Mage = 9.83 years, SD = 1.23; 42.5 % girls), who provided self-reported data on demographic variables, SNS use, self-esteem, depression, and self-compassion. Results indicated that after controlling for the children's gender and age, the partial mediating role of self-esteem between SNS use and depression was significant at low levels of self-compassion, marginally significant at high levels, and non-significant at mean levels. Moreover, both the first and second stages of the indirect effects were moderated by self-compassion. Specifically, the effects of SNS use on self-esteem were negative, non-significant, and marginally positive for children with low, middle, and high self-compassion, respectively. The interaction pattern of self-esteem and self-compassion on depression fit the protective-attenuating hypothesis: the protective effect of self-compassion was stronger for children with low self-esteem. This study extends our understanding of the underlying mechanisms linking SNS use to depression among children, which has both theoretical and practical implications for interventions for children's depressive symptoms. The limitations and theoretical and practical implications of this study are discussed.

摘要：
The main aim of this study was to investigate whether and how interpersonal uncertainty results in mobile phone addiction. Sampling 997 Chinese college students, we found that interpersonal uncertainty had positive predictive power for mobile phone addiction, and social and emotional loneliness mediated the link between interpersonal uncertainty and mobile phone addiction. Additionally, optimism moderated the direct effect of interpersonal uncertainty on mobile phone addiction and the first-stage mediating effect of interpersonal uncertainty on mobile phone addiction through social and emotional loneliness; that is, the higher the level of optimism among college students, the weaker the (in)direct effect of interpersonal uncertainty on mobile phone addiction. Our research findings reveal the role and mechanisms of interpersonal uncertainty in mobile phone addiction and shed light on the importance of reducing interpersonal uncertainty and fostering positive traits to effectively prevent and intervene in mobile phone addiction.

epigenetic regulation;histone cancer mutation;histone/nucleosome interaction;interaction network;nucleosome binding mode
摘要：
Nucleosomes represent hubs in chromatin organization and gene regulation and interact with a plethora of chromatin factors through different modes. In addition, alterations in histone proteins such as cancer mutations and post-translational modifications have profound effects on histone/nucleosome interactions. To elucidate the principles of histone interactions and the effects of those alterations, we developed histone interactomes for comprehensive mapping of histone-histone interactions (HHIs), histone-DNA interactions (HDIs), histone-partner interactions (HPIs) and DNA-partner interactions (DPIs) of 37 organisms, which contains a total of 3808 HPIs from 2544 binding proteins and 339 HHIs, 100 HDIs and 142 DPIs across 110 histone variants. With the developed networks, we explored histone interactions at different levels of granularities (protein-, domain- and residue-level) and performed systematic analysis on histone interactions at a large scale. Our analyses have characterized the preferred binding hotspots on both nucleosomal/linker DNA and histone octamer and unraveled diverse binding modes between nucleosome and different classes of binding partners. Last, to understand the impact of histone cancer-associated mutations on histone/nucleosome interactions, we complied one comprehensive cancer mutation dataset including 7940 cancer-associated histone mutations and further mapped those mutations onto 419,125 histone interactions at the residue level. Our quantitative analyses point to histone cancer-associated mutations' strongly disruptive effects on HHIs, HDIs and HPIs. We have further predicted 57 recurrent histone cancer mutations that have large effects on histone/nucleosome interactions and may have driver status in oncogenesis.

Face perception;Internet gaming disorder;N170;Reward positivity;Social reward
摘要：
Previous research has found that individuals with Internet gaming disorder (IGD) show different patterns of social function impairments in game-related and real-life social contexts. Impaired social reward processing may be the underlying mechanism according to the Social Motivation Theory. Thus, in this study, event-related potentials were recorded from 24 individuals with IGD and 24 healthy gamers during a social judgement task. We focused on reward positivity (RewP) elicited by game-related and real-life social rewards, and N170 elicited by game avatar faces and real faces. These indicators were used to explore the neurocognitive mechanism of impaired social reward processing in individuals with IGD and its relationship with early face perception. Results showed that (1) the RewP elicited by real-life social reward was considerably reduced in individuals with IGD relative to healthy gamers. (2) The N170 elicited by game avatar faces in individuals with IGD was larger than that elicited by real faces. However, the N170 was not associated with RewP in either group. (3) The score for IGD severity was correlated with the RewP elicited by real-life social reward and the N170 elicited by game avatar face. In conclusion, the present study suggests that the impaired social reward processing in individuals with IGD is mainly manifested in a decreased neural sensitivity to real-life social reward. Meanwhile, the reduced RewP elicited by real-life social reward and the enhanced N170 elicited by game avatar face might serve as potential biomarkers for IGD.

摘要：
Meaning in life refers to an individual's capacity to understand and grasp the meaning of their own existence, as well as being aware of the goals, tasks, or missions in their personal life. Previous studies have found that college students lack meaning in life, but physical exercise can enhance it. In this study, 3,196 college students completed self-report questionnaires to assess self-efficacy, life satisfaction, physical exercise, and meaning in life. The results revealed that the physical exercise not only influenced an individual's perceived meaning in life directly, but also influenced it through self-efficacy. Furthermore, it confirmed the chain mediating role of self-efficacy and life satisfaction, whereby engaging in physical exercise can ultimately impact meaning in life through self-efficacy and life satisfaction. This discovery can help educators create interventions to improve college students' physical exercise engagement and overall life satisfaction.
摘要：
Divergent thinking is assumed to benefit from releasing the constraint of existing knowledge (i.e. top-down control) and enriching free association (i.e. bottom-up processing). However, whether functional antagonism between top-down control-related and bottom-up processing-related brain structures is conducive to generating original ideas is largely unknown. This study was designed to investigate the effect of functional antagonism between the left inferior frontal gyrus and the right temporoparietal junction on divergent thinking performance. A within-subjects design was adopted for three experiments. A total of 114 participants performed divergent thinking tasks after receiving transcranial direct current stimulation over target regions. In particular, cathodal stimulation over the left inferior frontal gyrus and anodal stimulation over the right inferior frontal gyrus (Experiment 1), anodal stimulation over the right temporoparietal junction (Experiment 2), and both cathodal stimulation over the left inferior frontal gyrus and anodal stimulation over the right temporoparietal junction (Experiment 3) were manipulated. Compared with sham stimulation, the combination of hyperpolarization of the left inferior frontal gyrus and depolarization of the right temporoparietal junction comprehensively promoted the fluency, flexibility, and originality of divergent thinking without decreasing the rationality of generated ideas. Functional antagonism between the left inferior frontal gyrus (hyperpolarization) and right temporoparietal junction (depolarization) has a "1 + 1 > 2" superposition effect on divergent thinking.

摘要：
Abstract This study examined whether having the instructor wear a mask during a video lecture affects learning. In Experiment 1, college students watched an instructional video on the formation of lightning, in which an instructor who either did or did not wear a mask as she stood next to slides and lectured. Learners' learning outcomes did not differ significantly, but learners spent significantly less time looking at the instructor's face when she was masked. In Experiment 2, using a 2 (the instructor wore a mask or not) × 2 (slides were displayed or not) between‐subject design, college students learned about the process of water cycle from instructional videos. There was a significant interaction in which adding slides improved learning outcomes with a masked instructor, but not with an unmasked instructor. Adding a mask lowered student ratings of social presence with the instructor. Practical and theoretical implications are discussed.

摘要：
BACKGROUND: Although adding embodied instructors on the screen is considered an effective way to improve online multimedia learning, its effectiveness is still controversial. The level of realism of embodied on-screen instructors may be an influencing factor, but it is unclear how it affects multimedia learning. AIMS: We explored whether and how embodied on-screen instructors rendered with different levels of realism in multimedia lessons affect learning process and learning outcomes. SAMPLES: We recruited 125 college students as participants. METHODS: Students learned about neural transmission in an online multimedia lesson that included a real human, cartoon human, cartoon animal or no instructor. RESULTS: Students learning with cartoon human or cartoon animal instructors tended to fixate more on the relevant portions of the screen and performed better on retention and transfer tests than no instructor group. The real human group fixated more on the instructor, fixated less on the relevant portion of the screen and performed worse on a retention test in comparison to the cartoon human group. Fixation time on the instructor fully mediated the relationship between instructor realism and retention score. CONCLUSIONS: The addition of embodied on-screen instructors can promote multimedia learning, but the promotion effect would be better if the embodied instructor was a cartoon animal or cartoon human rather than a real human. This suggests an important boundary condition in which less realism of on-screen embodied instructors produces better learning processes and outcomes.

摘要：
Abstract Background Drawing is generally regarded as a promising learning strategy and has been explored in the touchscreen setting with different drawing modes. Although both a finger and a digital pencil can help individuals complete drawing activities effortlessly on touchscreen devices, there is no guarantee that they show the same effect on learning, which should be further tested. Objectives This study paid attention to the influence of drawing mode on learning processes and outcomes. Methods By means of the eye tracking technique, this study recruited college students as participants who were required to learn instructional materials consisting of actual (Experiment 1) or fictitious (Experiment 2) terms and definitions to test the effects of touchscreen‐based finger drawing versus pencil drawing on visual attention, learning performance as well as motivation. Results and Conclusions Across both experiments, learners showed more fixation count in areas of interest, and also more transition count between these areas for the finger drawing condition as compared to the pencil drawing condition. Recall performance on the studied definitions in the finger drawing condition was better than that in the pencil drawing condition. However, learners were subjectively less motivated to use a finger to draw than a digital pencil. Implications These findings show contributions to the emphasis of importance of drawing mode when the generative drawing activity is applied to touchscreens.

BACKGROUND: Burnout has received considerable attention in recent years because of the adverse consequences for people. Theoretical perspectives propose that problematic internet use is a significant potential risk for burnout. Despite a plethora of studies showing a positive association between problematic internet use and burnout, there remains a contentious debate regarding the extent and direction of this association. METHODS: This study aims to perform a three-level meta-analysis to evaluate the strength of the relationship between problematic internet use and burnout through a quantitative synthesis of eligible studies published until April 2023. RESULTS: A total of 42 studies with 54,121 participants and 103 effect sizes were identified. The results indicated a positive, moderate, and significant association between problematic internet use and burnout. Furthermore, the subgroup analysis found that this association was moderated by population, dimension of burnout, and the measure of burnout, however, some study features (i.e., region, type of problematic internet use, gender, and publication year) could not explain the heterogeneity across individual studies. LIMITATIONS: Studies included in the current meta-analysis mainly used cross-sectional designs, which limited the potential to make inferences on the causal relationship between problematic internet use and burnout. CONCLUSIONS: Individuals with problematic internet use have exhibited higher levels of burnout. Overall, these findings develop a deeper understanding of this association between problematic internet use and burnout and have implications for the direction of future research and interventions.
