ABSTRACT
OBJECTIVE: To explore the influence of work pressure and psychological capital on job burnout of college teachers. METHODS: A total of 287 teachers from 7 universities in Nanjing City were selected as the research subjects using the convenient sampling method. The Maslach Burnout Inventory, Job Stress Scale for University Teachers and Psychological Capital Questionnaire were used to investigate their job burnout, job stress and psychological capital. RESULTS: The total scores of job burnout and job stress were(42.9±12.5) and(48.5±12.4) respectively, and the occurrence of job burnout was 64.1%. The total scores of psychological capital was(106.7±14.7), and the scores of the four dimensions including self-efficacy, hope, resilience and optimism were(27.6±4.6),(26.7±4.8),(27.0±4.2) and(25.4±3.8) respectively. The total score of job stress was positively correlated with the total score of job burnout [correlation coefficient(r)=0.41, P<0.01]. The total score of psychological capital, self-efficacy, hope, resilience and optimism were negatively correlated with the total score of job burnout(r values were-0.42,-0.28,-0.36,-0.36 and-0.42, respectively, P<0.01). The results of multiple linear regression analysis showed that after adjusting the influence of confounding factors and excluding other confounding factors, the higher the job stress, the higher the job burnout level(P<0.01), the higher the psychological capital optimism dimension score, the lower the job burnout level(P<0.01). CONCLUSION: The job stress and psychological capital of college teachers can independently affect their job burnout level, with a dose-effect relationship.
ABSTRACT
Objective To investigate the effecacy of open reduction internal fixation in cases with rib fracture. Methods The pain scores,respiratory related clinical indicators change of 81 rib fractuure cases underwent open reduction internal fixation surgery were ob-served. A comparison was made between the surgical group and the non-surgical group of 37 cases on pain scores trend and hospital stay. Re-sults All operations were successfully completed and postoperative recovery was good. Postoperative pain scores and respiratory rate was sig-nificantly lower(P=0. 000),Oxygen saturation was significantly higher(P=0. 002),the proportion of expectoration difficult,dyspnea and ac-tivities inconvenience were significantly lower(P<0. 05). Pain scores of surgical group significantly decreased after surgery peak hours that was the fourth day hospitalized,but the overall decline of pain scores in non-surgical group was slow. The hospital stay between the surgical group and the non-surgical group was not significantly different(P=0. 084). Conclusion The efficacy of open reduction internal fixation is significant to rib fracture with exact surgery indications,and appropriate timing of surgery is the fourth day after admission.
ABSTRACT
Objective To investigate the effect of video-assisted thoracoscopic surgery( VATS) in thoracic disease,and the feasibility to carry out VATS for basic hospital. Methods The data of VATS treatment were collected to compare the differences between study group and control group,and evaluate the the feasibility to carry out VATS for basic hospital. Results The operation time was (100. 75±22. 72) min, blood loss was (54. 27±26. 21) mL,postoperative drainage was (920. 67±171. 99) mL. The postoperative complications were fewer,post-operative hospital stay was shorter,incision time was shorter(P=0. 000) and pain scores was lower(P=0. 000) in study group than that in control group. Basic hospital has the capacity to conduct this technical. Conclusion VATS is feasible to carry out in basic hospital.
ABSTRACT
Objective To investigate the value of video-assisted thoracoscopic surgery(VATS)in the treatment of coagulated hemothorax.Methods A prospective randomized controlled study.Between July 2005 and July 2007,62 patients with coagulated hemothorax were enrolled in this study.The patients were randomly divided into VATS and traditional thoracotomy groups(31 in each).The pathophysiological parameters of the two grups were compared.Results No significant difference in the sex,age,property and location of the wound,and rate of complicated injuries was noticed between the two groups.The mean operation time,duration of postoperative drainage,and postoperative hospital stay of the VATS group were significantly shorter than those in the traditional group [(52.1?24.4)min vs(120.2?47.2)min,t=-7.136,P=0.000;(1.7?0.7)d vs(4.8?1.8)d,t=-8.937,P=0.000;and(12.6?2.4)d vs(18.0?8.9)d,t=-3.262,P=0.002;respectively];and the mean intraoperative blood loss and the volume of thoracic drainage of the VATS group were significantly lower than those in the traditional group [(137.1?14.6)ml vs(203.2?53.4)ml,t=-6.648,P=0.000;and(181.3?37.9)ml vs(253.9?64.0)ml,t=-5.435,P=0.000,respectively].No significant difference in the rate of complications existed between the two groups(0 vs 1 case,?2=0.000,P=0.000).Conclusion Video-assisted thoracoscopy is feasible and safe for coagulated hemothorax and is worth being widely used.
