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, P<0.01). Expressive suppression contributed significantly positive correlation to the total and the dimension scores of PCL-C (r=0.187-0.243, P<0.05 or 0.01). Expressive suppression was found to contribute significantly to the explained variance in mothers′ PTSD (P<0.05), whereas no association was found between PTSD and cognitive reappraisal (P>0.05). 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.

Objective:To probe into the status characteristics and the dynamic change trend of the psychological stress among medical staff at four time points after exposed to blood-borne pathogen.Methods:A longitudinal study was carried out among 78 medical personnel in this study,with 67 of hepatitis B virus,5 of hepatitis C virus,4 of HIV and 2 of treponema pallidum respectively.Perceived stress scale (PSS-4),Post-traumatic stress disorder Checklist-5 (PCL-5),Hospital anxiety and depression scale (HADS) were used to assess the psychological status,including perceived stress,post-traumatic stress symptom,anxiety and depression at the four times.Data analysis was performed using repeated measures analysis of variance (RMANOVA) and paired sample t test to explore time effect of the psychological stress reaction in the exposed population.Results:The scores of PSS-4,PCL-5,HADS-A,and HADS-D increased from exposure,and gained highest at one month after exposed,then gradually declined with time (Ps ＜ 0.05).Conclusion:It suggests that the levels of perceived stress,post-traumatic stress symptom,anxiety,depression may be the highest at one month after exposed.

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.

Objecive To design and develop a simulated maritime rescue training platform to emulate different sea conditions and carry out maritime rescue training.Methods Corresponding computer program was used to control a 3 degreeof-freedom electric platform,and the rolling,pitching and heaving of the ambulance boat were simulated by setting vibration frequency and displacement.An operating training room was set up and equipped with necessary emergency devices.Results By changing the frequency and displacement of the training platform,the operating environment in the ambulance boat was simulated under the second to fifth grades of sea conditions to execute the training for antivertigo,fine operation and nursing.Conclusion The platform facilitates the medical staff to be familiar with maritime environment,master treatment techniques at different sea conditions and enhance support efficiency.

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.

Objective To establish an assay for the detection of Streptococcus pneumoniae by real-time fluorescence quantititive polymerase chain reaction (PCR).Methods Special primers and probe for the autolysin A (lytA)gene were designed.The sensitivity and specificity of primers and probe were studied,and cut-off of cycle threshold was assayed.158 clinical specimens were confirmed by real-time fluorescence quantitative PCR and bacterial culture method.Results Primer and probe design for LytA gene could sensitively detect serotype Streptococcus pneumoniae strains of common pathogenic,and the sensitivity was 100 copies.Among 35 strains of Streptococcus pneumoniae,34 cases were detected to be positive for Streptococcus pneumoniae by real-time fluorescence quantitative PCR,while 1 case was detected to be negative;among 15 strains of non-Streptococcus pneumoniae, all were detected to be negative.Among the 158 clinical sputum specimens,34 cases with Streptococcus pneumoniae were detected by real-time fluorescence quantitative PCR,while only 10 cases with Streptococcus pneumoniae were detected by the culture method.White blood cells count and time in hospital of cases with Streptococcus pneumoniae were higher than those of cases without Streptococcus pneumoniae (P <0.05 ). Conclusion Real-time fluorescence quantitative PCR is a sensitive and specific assay for the detection of Streptococcus pneumoniae.It can be used for the diagnosis of Streptococcus pneumoniae.

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 explore the effect of Dahuang-Zhidan decoction on postoperative peripheral inflammatory factors and prognosis in patients with hypertensive cerebral hemorrhage. Methods: A total of 103 patients with hypertensive cerebral hemorrhage in our hospital from May 2015 to January 2017 were divided into two groups according to the randomly number tables method. The control group (n=51) were treated by conventional treatment of western medicine, and the observation group (n=52) were treated with Dahuang-Zhidan decoction based on the treatment of the control group.The inflammatory factors, including interleukin-6 (IL-6), tumor necrosis factor (TNF-α), highly sensitive C-reactive protein (hs-CRP), interleukin-1β (IL-1β) in hematoma lesions after treatment for 1st, 7th day between two groups were measured. The comparisons of awake rate after treatment for the 7th, 14th, 30th day between two groups was conducted. The National Institute of Health Stroke Scale (NIHSS) scores after treatment for 30th, 90th day between two groups was launched. The Glasgow Prognosis Score (GOS) between two groups was compared at the 90th day. Results: After treatment for 7 d,the postoperative peripheral inflammatory factors IL-6 (90.55 ± 18.89 pg/ml vs. 122.71 ± 19.62 pg/ml, t=-6.892), TNF-α (172.26 ± 29.85 pg/ml vs. 229.02 ± 30.34 pg/ml, t=-10.332), hs-CRP (137.55 ± 24.60 pg/ml vs. 162.14 ± 23.98 pg/ml, t=-8.615), IL-1β (95.57 ± 18.92 pg/ml vs. 110.65 ± 17.38 pg/ml, t=-3.594) in the observation group was significantly lower than those in the control group (P<0.05). After treatment for 7, 14, 30 d, the awake rate was 44.23% (23/52), 69.23% (36/52), 90.38% (47/52) in the observation group, which was significantly higher than those in the control group (χ²=3.977, 4.355, 4.499, P<0.05). After treatment for 30, 90 d, the NIHSS scores (12.24 ± 6.38 vs. 16.27 ± 7.69, t=-2.906), (5.39 ± 6.24 vs. 9.94 ± 8.11 , t=-3.198) in the observation group were significantly lower than those in the control group (P<0.05). After treatment for 90 d, the distribution of GOS scores in the observation group was significantly different from the control group (Z=-2.400, P=0.016). Conclusions The Dahuang-Zhidan decoction in the treatment of patients with hypertensive cerebral hemorrhage significantly inhibit postoperative the inflammatory response around hematoma lesions, and improve the neurological function, the awake rate and the qualify of life.
