Objective To compare the clinical efficacy between bone cement-augmented pedicle screw fixation and bone filling vertebroplasty for stable osteoporotic thoracolumbar burst fracture (TBF).Methods From August 2014 to August 2017,48 patients with stable osteoporotic TBF but no neurological symptoms were treated at Department of Orthopedics,The First Affiliated Hospital to Chongqing Medical University.Those undergoing bone cement-augmented pedicle screw fixation were assigned into Group A while those undergoing bone filling vertebroplasty into Group B.The clinical efficacy was evaluated by comparing visual analogue scale (VAS) for pain assessment,Oswestry disability index (ODI),compression ratio of anterior vertebral height,and cobb kyphotic angle between preoperation and postoperation.The 2 groups were compared in terms of operation time,bone cement consumption,blood loss,hospital stay and relative medical costs.Results Of the 48 patients included in this study,27 were in Group A and 21 in Group B.The 2 groups were comparable as their baseline characteristics were insignificantly different (P ＞ 0.05).At 3 days after operation,the VAS (2.8 ± 1.0) and ODI (26.0 ±3.5) scores for group B were significantly lower than those for group A (4.6 ± 1.3 and 34.3 ± 2.9) (P ＜ 0.05).In group A at 3 months after operation and final follow-up,the VAS (2.9 ±0.9 and 2.3 ±0.7) and ODI (24.7 ±3.1 and 23.1 ±4.6) scores were significantly lower than those at 3 days after operation (4.6 ± 1.3 and 34.3 ± 2.9) (P ＜ 0.05).In group B at 3 months after operation and final follow-up,the VAS (2.8 ±0.9 and 2.3 ± 1.0) and ODI (23.8 ±3.7 and 22.8 ± 5.6) scores were insignificantly better than those at 3 days after operation (2.8 ± 1.0 and 26.0 ± 3.5) (P ＞ 0.05).At 3 days and 3 months after operation and final follow-up,group B had significantly smaller compression ratios of anterior vertebral height (81.1％ ± 3.7％,81.1％ ± 3.4％ and 75.6％ ± 5.8％) than group A did (91.4％ ±4.4％,90.1％ ±2.9％ and 83.5％ ±4.4％) but significantly larger cobb kyphotic angles (17.0° ± 4.0°,18.0° ± 3.5 ° and 22.1 ° ± 3.6°) than group A (14.0° ± 3.2°,14.3° ± 5.5° and 19.2° ± 3.2°) (P ＜ 0.05).The compression ratio of anterior vertebral height and cobb kyphotic angle at the final follow-up in all the patients were significantly improved compared with those at 3 days and 3 months after operation (P ＜ 0.05).Group B had significantly less operation time (51.5 ±7.3 min),blood loss (16.0 ± 8.2 mL),hospital stay (3.4 ±0.9 d) and medical costs per person (34,000 ±4,000 RMB yuan) than group A (91.5 ± 9.8 min,77.4 ± 16.5 mL,8.7 ± 2.2 d and 55,000 ± 9,000 RMB yuan),but significantly larger bone cement consumption (5.1 ± 0.7 mL) than group A (1.9 ± 0.7 mL) (P ＜ 0.05).Conclusion For patients with stable osteoporotic TBF,both bone cement-augmented pedicle screw fixation and bone filling vertebroplasty can lead to similar clinical outcomes,but the latter may have advantages of less invasion,faster recovery and lower medical costs.

Objective:To understand the current situation of work performance and influencing factors of medical staff in tertiary hospitals in Henan Province,in order to provide references for improving their performance level.Methods:An electronic questionnaire was used to investigate the work engagement and work performance of medical staff in a sample hospital in Henan Province,and multiple regression analysis was used to explore the relationship between work engagement and work performance.Results:The total score of medical staff's job performance was 45.18±5.78;Cronbach's α coefficient of the questionnaire's reliability ranged from 0.870 to 0.964;medical staff's job commitment was positively correlated with their job performance;and the highest level of educational attainment,occupational category,and job commitment were the main influencing factors of job performance(P＜0.05).Conclusion:There is still much room for improvement in the work performance of medical staff in tertiary hospitals in Henan Province,and hospitals should focus on improving the work capacity of medical staff and actively improving work engagement in order to enhance the level of medical staff performance.

Objective To investigate the effects of transcutaneous electrical acupoint stimulation at Neiguan combined with Danzhong on intraoperative remifentanil dosage and early postoperative pain in pa-tients undergoing radical mastectomy.Methods A total of 153 female patients undergoing radical mastecto-my under general anaesthesia aged 18-64 years,BMI 18.5-30.0 kg/m2 and ASA physical status Ⅰ or Ⅱwere enrolled.The patients were randomly assigned into three groups:single-acupoint(Neiguan)group,dual-acupoint(Neiguan and Danzhong)group and control group,51 patients in each group.TEAS for 30 minutes at different points(Neiguan combined with Danzhong for the dual-acupoint group,Neiguan for the single-acupoint group,no stimulation for the sham group)were given before anaesthesia induction.30 mi-nutes of disperse/dense stimulation of 2/10 Hz with an intensity of 4-11 mA was used.The consumption of remifentanil,time to recall and to extubation were recorded.The visual analogue scale(VAS)pain score in PACU and 24 hours after surgery,and patient satisfaction scores was recorded.Results The intra-operative remifentanil consumption in the dual-acupoint group was significantly less than groups single-acupoint and sham(P＜0.05).Patient satisfaction score 24 hours after surgery was significantly higher in the dual-acu-point group than those in groups single-acupoint and sham(P＜0.05).The VAS scores in PACU and 24 hours after surgery had no significantly differences among the three groups.Conclusion Compared with single-acupoint,stimulation at Neiguan combined with Danzhong in patients undergoing radical mastectomy induced stronger remifentanil-sparing effect and higher patients'satisfaction after radical mastectomy.
