ABSTRACT
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.
ABSTRACT
Objective To investigate the regulation of metabolize characteristic of some antibiotics in ACST in human bile, and provide the theoretic basis for physician selecting antibiotic rationally when biliary tract has been infected. Methods Samples of ACST in human bile were obtained by ERCP + ENBD, contents of Cefradine, Cefoperazone, Ceftriaxone, Ciprofloxacin and Lomefloxacin in human bile were simultaneously measured by HPLC method. Results After antibiotics were given through iv 0. 25 ～ 1. 5 hour, an increase was observed in contents of all antibiotics in bile, and the changes of Ceftriaxone and Ciprofloxa-cin were the most significant ( P <0.01). Ceftriaxone and Ciprofloxacin had a higher Cmax than other antibiotics, and Cefoperazone had a longer tl/2. Conclusion As maintaining a little time to tmax , a higher Cmax and a longer tl/2 in the bile by iv, Cefradine and Ciprofloxacin are recommended in the patient with ACST.
ABSTRACT
OBJECTIVE:To provide reference for drug management in clinical trial process in hospital. METHODS:To summarize the common problems of current drug control in clinical trial process and analyze their harmfulness. Some countermeasures were put forward to resolve those problems. RESULTS & CONCLUSIONS:At present uniform management mode hasn’t been established for drug control in clinical trial institutions. Realizations on the importance of drug control are different from one another. There are several factors which affect clinical trials even result in undesirable consequence. The institution should formulate scientific,effective and practical management standards and operation process to improve the quality of drug control and ensure safety, scientificity and reliability of clinical trials.
