Development of reproductive motivation scale for infertile women and its reliability and validity / 中华行为医学与脑科学杂志

Objective:To preliminarily develop a fertility motivation scale for infertile women (FMS-IW) and test its reliability and validity.Methods:The FMS-IW was developed according to the theory of self-determination and Maslow's hierarchy of needs, and the original item pool was established through clinical psychological counseling practice experience, literature review, consulting clinical psychotherapists, interviewing with infertile women and open-ended questionnaires. The original scale was constructed on item analysis and exploratory factor analysis in 257 infertile women. The formal version of FMS-IW was further adapted by Delphi method and tested in another 392 women to conduct confirmatory factor analysis and reliability test. Furthermore, 56 participants of 392 women were randomly retested with FMS-IW after two weeks.SPSS 25.0 and Amos 24.0 software were used for Spearman analysis, exploratory factor analysis and confirmatory factor analysis.Results:Exploratory factor analysis showed that the FMS-IW was composed of 16 items consisting of two factors: autonomous fertility motivation and controlled fertility motivation. The cumulative variance contribution rate was 64.18%. Confirmatory factor analysis showed that the model fitted well ( χ2/ df=3.292, RMSEA=0.077, SRMR=0.055, GFI=0.902, AGFI=0.871, IFI=0.938, CFI=0.938, TLI=0.928). The Cronbach's α coefficient of the FMS-IW was 0.908. The Cronbach's α coefficient for autonomous and controlled fertility motivation was 0.911 and 0.928, respectively. The parity split-half coefficient of the formal version of FMS-IW was 0.870. The test-retest reliability of the formal version of FMS-IW was 0.823. Conclusion:The FMS-IW has good reliability and validity, and can be used as an effective tool to measure fertility motivation in infertile women.

Predictors of nurses′ job burnout and depressive symptoms: A dominance analysis of diverse emotion regulation strategies / 中国实用护理杂志

Objective@#To examine the relative importance of four emotion regulation strategies (i.e. cognitive reappraisal, expressive suppression, rumination and mindfulness) in explaining job burnout and depression of nurses.@*Methods@#We conducted a cross-sectional study with questionnaires for 1 037 nurses from two general hospitals. Maslach Burnout Inventory-Human Service Survey (MBI-HSS), the Patient Health Questionnaire-9 (PHQ-9), Emotion Regulation Questionnaire (ERQ), Ruminative Responses Scale (RRS) and Short Inventory of Mindfulness Capability (SIM-C) were assessed.@*Results@#Dominance analysis revealed that in terms of job burnout, rumination, cognitive reappraisal and mindfulness could explain 41.38% (0.132/0.319), 30.09% (0.096/0.319) and 28.53% (0.091/0.319).

Porphyromonas gingivalis disrupts vascular endothelial homeostasis in a TLR-NF-κB axis dependent manner / 国际口腔科学杂志·英文版

Cardiovascular disease is still the leading cause of mortality worldwide. Vascular endothelial dysfunction is viewed as the initial step of most cardiovascular diseases. Many studies have indicated that periodontal pathogens, especially Porphyromonas gingivalis, are closely correlated with vascular endothelial homeostasis, but the function of P. gingivalis and the underlying mechanisms are still elusive. To illuminate the effects and elucidate the mechanisms of P. gingivalis on endothelial structural integrity, we developed P. gingivalis infection models in vivo and in vitro. Endothelial cell proliferation, differentiation and apoptosis were detected. Here, we showed that P. gingivalis can impair endothelial integrity by inhibiting cell proliferation and inducing endothelial mesenchymal transformation and apoptosis of endothelial cells, which reduce the cell levels and cause the endothelium to lose its ability to repair itself. A mechanistic analysis showed that TLR antagonist or NF-κB signalling inhibitor can largely rescue the damaged integrity of the endothelium caused by P. gingivalis, suggesting that TLR-NF-κB signalling plays a vital role in vascular endothelial homeostasis destroyed by P. gingivalis. These results suggest a potential intervention method for the prevention and treatment of cardiovascular disease.

Relation of neuroticism and resilience to posttraumatic stress disorder and posttraumaticgrowth in patients with burns during rehabilitation / 中国心理卫生杂志

Objective:To investigate the characteristics of posttraumatic stress disorder (PTSD) symptom and posttraumatic growth (PTG) in the patients with burns during rehabilitation, and the relationships among PTSD symptom, PTG, neuroticism and resilience.Methods:A cross-sectional study was carried out among 110 patients with burns during rehabilitation.The PTSD Check-list-Civilian Version (PCL-C), Posttraumatic Growth Inventory (PTGI), Five Factors Inventory-Neuroticism Subscale (FFI-N) and the 10-item Connor-Davidson Resilience Scale (CD-RISC) were used.Result:A significant effect of different groups of marital status (F=5.66, P=0.019), annual household income (F=7.97, P=0.006), and neuroticism (F=34.24, P＜0.001, Partial η2=0.259) on PCL-C scores.A significant effect of different groups of gender (F=6.44, P=0.013) and resilience (F=14.87, P＜0.001, Partial η2=0.132) were significant for PTG scores.There existed a significant interaction between neuroticism and resilience on PTG (F=4.47, P=0.037, Partial η2=0.044).Conclusion:Being married, low annual household income, and high levels of neuroticism were associated with high PTSD symptom levels.Being female and high levels of resilience were associated with high PTG levels.Resilience moderated the effect of neuroticism on PTSD symptoms.

Objective To explorepredictive factors of psychological stress reaction of medical staff members with blood-occupational exposure and to provides scientific basis for the hospital administrators toprovide psychological support and interventionfor medical staff members with blood-occupational exposure. Methods Seventy-eight medical staff members with blood-occupational exposure were recruited as participants. The Socio-demographic Questionnaire, Posttraumatic Stress Disorder Checklist-5, the Perceived Stress Scale, the Hospital Anxiety and Depression Scale, the Ruminative Responses Scale and the Emotion Regulation Questionnaire were used to evaluate the participants' psychological stress reactionat different stages and the styles of their emotion regulation. Correlation analysis and Hierarchical Regression analysis were used to analyze the predictive factors of psychological stress reaction of medical staff members with blood-occupational exposure. Results Ruminative thinking and emotion regulation can predict the psychological stress reaction of medical staff members with blood-occupational exposure at different stages. Conclusions According to the psychological stress reaction and ruminative thinking of medical staff members with blood- occupational exposure, psychological intervention should be implemented within one month to decrease the psychological trauma of medical staff members with blood-occupational exposure.

Mediating effect of emotion regulation on relationship between occupational stress and job burnout of nurses / 中国实用护理杂志

Objective To explore whether emotion regulation mediates the relationship between occupational stress and job burnout in a large sample of nurses, in order to provide a targeted intervention. Methods Chinese Nurses Stressor Scale, Maslach Burnout Inventory-Human Services Survey, Emotion Regulation Questionnaire and Ruminative Responses Scale were used to investigate 602 nurses working in three tertiary hospitals in Jinan. SPSS 16.0 and AMOS 17.0 software were used to analyze the data. Results Job burnout were positively correlated with stressors, expression suppression and rumination (r=0.112–0.576, P<0.01), and negatively correlated with cognitive reappraisal (r=-0.277, P<0.01). Stressors were positively correlated with expression suppression and rumination (r = 0.140–0.403, P <0.01), and negatively correlated with cognitive reappraisal (r =-0.110, P < 0.01). Occupational stress could make a positive role on job burnout directly. Moreover, in the indirect approach, occupational stress could make a positive role on job burnout through the mediating role of cognitive reappraisal and ruminative, but not expression suppression. Conclusions Cognitive reappraisal and ruminative partially mediated the relationship between occupational stress and job burnout.

Relationship between self-reported symptoms of depression and anxiety and the cumulative effect of childhood trauma in pregnant women / 中国实用护理杂志

Objective To probe into the relationship of the cumulative effect of childhood trauma types and symptoms of depression and anxiety among pregnancy women. Methods A total of 276 cases of pregnancy women were investigated by using Childhood Trauma Questionnaire (CTQ- SF), the Edinburgh Postnatal Depression Scale (EPDS) and the State-Trait Anxiety Inventory (STAI). Results The cumulative number of childhood trauma types were positively correlated with the scores of EPDS, state anxiety and trait anxiety (r=0.245, 0.262 and 0.292, P<0.01);the scores of CTQ-SF, EPDS, state anxiety and trait anxiety of multi-CTQ group were higher than that of non-CTQ group, as well as the positive rate of depression symptom and anxiety symptom (P<0.05 or 0.01);Logistic regression analysis showed that the cumulative number and accumulation group of CTQ may be predictors or risk factors of depression and anxiety of women during pregnancy, and existed cumulative effect. When the cumulative number of childhood trauma types more than two types, it increased 2.37 and 3.12 times likelihood of depression and state anxiety comparing to non-CTQ group. Conclusions It suggested that childhood trauma experience may be a risk factors of depression and anxiety during pregnancy, and exist cumulative effect.

Relationship between posttraumatic stress disorder and emotional regulation strategies of mothers ;with neonates hospitalized in the neonatal intensive care unit / 中国实用护理杂志

Objective To investigate the occurrence of posttraumatic stress disorder (PTSD) and the relationship between PTSD and emotional regulation strategies of mothers with neonates hospitalized in the neonatal intensive care unit (NICU). Methods One hundred and twenty-seven postpartum women with neonate hospitalized in the NICU were selected from a general hospital. All the cases were investigated by PTSD check list-Civilian version (PCL-C) and emotion regulation questionnaire (ERQ). Results The incidence of PTSD of postpartum women with neonate in NICU was 13.4%(17/127). The expressive suppression scores in positive PTSD group were (17.76±2.46) points,which were significantly higher than (14.16 ± 5.14) points in negative PTSD group (t=-4.659, P0.05). Conclusions The admission of neonates to the NICU is a stressful event for mothers, which could cause PTSD symptoms. PTSD has a closer relationship with expressive suppression, rather than cognitive reappraisal. Therefore, health workers should instruct mothers with neonates in NICU to regulate emotions by appropriate coping strategies, decreasing the possibility of psychological problems, promoting the mental health of women in the perinatal period.
