Objective To explore the relationship among clinicians' work pressure,perceived social support and compassion fatigue,and to provide a new prospective for the localization studying of intervention and treatment to compassion fatigue.Methods Data of scale for occupational stressors on clinician,perceived social support scale and professional quality of life scale were collected from a sample of 533 clinicians and analyzed with structural equation modeling to study the relationship among clinicians' work pressure,perceived social support and compassion fatigue.Results (1)Work pressure(2.40±0.45),burnout (2.14±0.54) and secondary traumatic stress(1.93±0.60) scores of the clinicians with high perceived social support were significantly lower than that of the clinicians with low perceived social support (2.78±3.67,2.73± 0.59,2.32±0.71;t=7.68,-9.44,8.77,5.07;P＜0.01).Compassion satisfaction scores (4.15±0.63) of the clinicians with high perceived social support were significantly higher than that of the clinicians with low perceived social support (3.40±0.71,t =-9.44,P＜0.01).(2) According to relevant results,work pressure was significantly negative correlation with both perceived social support (r=-0.34,P＜0.01) and compassion satisfaction (r=-0.44,P＜0.01),and significantly positive correlation with both burnout (r=0.69,P＜0.01) and secondary traumatic stress(r=0.53,P＜0.01);while perceived social support was significantly positive correlation with compassion satisfaction (r=0.42,P＜0.01),and significantly negative correlation with burnout (r=-0.40,P＜0.01) and secondary traumatic stress(r=-0.26,P＜0.01).(3) According to the results of structural equation modeling,perceived social support played a partly mediating role in the effect of work pressure toward compassion satisfaction and fatigue with the intermediary effect of 55.4％ and 12.5％.Conclusion Perceived social support plays a mediation role between work pressure and compassion fatigue for clinicians,and better social support of the clinician is beneficial to clinicians mental health level.

Objective To explore the possibility of guiding clinical fast diagnosis and rational use of drugs by rapid detection of plasma digoxin concentration(PDC) with i4000.Methods The plasma samples of 132 patients were collected and digoxin concentration was detected by i4000,and the relationship between PDC and clinical effect was analyzed.Then,the regularities of distribution of digoxin concentration also analyzed according to the age and PDC.The patients whose PDC beyond the effective concentration 0.8 ～ 2.0 μg/L,were treated with adjusted dose respectively according to the circumstance and continuous monitoring of PDC.Results In 132 cases,PDC of 106 patients within the therapeutic dose,accounted for 80.30％,and the total effective rate was 86.36％ after treatment.The effective rates in ＜0.8μg/L group,0.8 ～2.0μg/L group and ＞2.0μg/L group were 10.91％,95.28％and 75.00％,respectively.After dosage adjusted for 1 1 cases with PDC ＜ 0.8μg/L and 4 cases ＞ 2.0μg/L,the PDC returned to the effective concentration.The PDC in over 60 years old group was higher than that in 50 ～ 60 years old group.Poisoning symptoms occurred in 7 cases,and symptoms disappeared through adjustment dosages.Conclusion The PDC detection by Abbott i4000 is rapid and easy to operate,and the result is accurate and reliable.

Objective To study the relationship between social support and subjective well-being(SWB) of labor workers.Methods 1038 labor workers in Shenzhen were evaluated by subjective well-being scale for Chinese citizen (SWBS-CC), social support rating scale ( SSRS ).Results There was no significant difference in SWB between male and female( ( 63.51 ± 11.03 ) vs ( 63.22 ± 12.02 ), t = 0.389, P ＞ 0.05 ).The 30 ～ 49 age group's score was significantly higher than the 16 ～29 age group's( (62.80 ± 11.80) vs (64.54 ± 11.28), t=2.21, P ＜ 0.05 ).The married group's score was significantly higher than the unmarried group's ( (62.50 ± 12.18)vs (64.27 ± 10.80 ), t= 2.44, P ＜ 0.05 ).Social support was significant positively correlative with subjective well-being ( r=0.075 ～0.391, P＜0.05), except support availability was not correlative with both subscales.Subjective support, support availability and objective support were significantly positive predictions of SWB, meanwhile subjective support was the biggest( β =0.297).Conclusion Subjective well-being of the labor workers in Shenzhen have significant relationship with age and social support.To increase the emotional support for the labor workers could possibly help to improve their subjective well-being.

Objective:To investigate the status quo of psychological characteristics of mindfulness, family concern and rehabilitation compliance of patients undergoing hip arthroplasty and to explore the internal relationships between psychological characteristics of mindfulness, family concern and rehabilitation compliance of patients undergoing hip arthroplasty in order to clarify the mediating effect of psychological characteristics of mindfulness.Methods:Using the convenient sampling method, a total of 101 patients who underwent hip arthroplasty in Department of Orthopedics in Peking University Shenzhen Hospital from July 2017 to June 2018 were selected as research objects. Five Facet Mindfulness Questionnaire (FFMQ) , Family Adaptability, Partnership, Growth, Affection, and Resolve (Family APGAR) Index and Rehabilitation Compliance Scale were used to conduct questionnaire surveys. The Pearson correlation analysis were used to analyze the correlations between rehabilitation compliance, family concern and psychological characteristics of mindfulness. Then a hypothetical model was established to analyze the mediating effect of psychological characteristics of mindfulness between family concern and rehabilitation compliance.Results:Finally, 90 valid questionnaires were collected. The total scores of FFMQ, Family APGAR Index and Rehabilitation Compliance Scale were respectively (115.01±8.99) , (7.27±0.84) and (5.27±0.92) . The psychological characteristics of mindfulness, family concern and rehabilitation compliance of patients with hip replacement were positively correlated ( r=0.562, 0.491; P<0.01) . The constructed mediation model showed that family concern had a positive predictive effect on rehabilitation compliance ( P<0.05) , psychological characteristics of mindfulness had a positive predictive effect on rehabilitation compliance ( P<0.05) , and psychological characteristics of mindfulness played a mediating role between family concern and rehabilitation compliance of patients with hip replacement. Conclusions:In this study, family concern, psychological characteristics of mindfulness and rehabilitation compliance of patients with hip replacement are all at a moderate level. Psychological characteristics of mindfulness of patients, family concern and postoperative rehabilitation compliance are positively correlated, and psychological characteristics of mindfulness has a mediating role between family concern and rehabilitation compliance. Medical staff can carry out mindfulness psychological interventions for patients with hip replacement to improve family concern and promote rehabilitation compliance of patients.

Autologous ozonized blood transfusion(AOBT) is a therapy of re-transfusion of 100-200 mL of autologous blood after shaking and agitation with appropriate amount of oxygen-ozone in vitro. The oxidation of blood through the strong oxidation of ozone can enhance the non-specific immune response of the body, regulate the internal environment and promote health. This therapy has been increasingly applied in clinical practice, while no unified standard for the operation process in terms of ozone concentration, treatment frequency and treatment course had been established. This operation process of AOBT is primarily explored in order to standardize the operation process and ensure its safety and efficacy.
