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 investigate the relationship between serum interleukin-1β(IL-1β),C-reactive pro-tein to albumin ratio(CAR)and heparin-binding protein(HBP)levels and secondary pulmonary Candida albi-cans infection during chemotherapy in patients with lung cancer.Methods A total of 175 patients with lung cancer admitted to this hospital from January 2018 to April 2022 were selected,and all patients were treated with chemotherapy.According to whether they had secondary pulmonary Candida albicans infection,they were divided into infection group(37 cases)and non-infection group(138 cases).The clinical data,serum levels of IL-1β,HBP and CAR were compared between the two groups.Multivariate Logistic regression analysis was used to analyze the influencing factors of secondary pulmonary Candida albicans infection in patients with lung cancer during chemotherapy.The receiver operating characteristic(ROC)curve was used to analyze the pre-dictive value of serum IL-1β,CAR and HBP for secondary pulmonary Candida albicans infection during chemo-therapy,and the prognosis of lung cancer patients with different serum IL-1β,HBP levels and CAR were com-pared.Results There were significant differences in smoking,pathological stage,diabetes mellitus,chemo-therapy cycle,chronic obstructive pulmonary disease and anatomical location between the infection group and the non-infection group(P＜0.05).The serum levels of IL-1β,HBP and CAR in the infection group were higher than those in the non-infection group(P＜0.05).Multivariate Logistic regression analysis showed that smoking,diabetes,anatomical site,chronic obstructive pulmonary disease,pathological stage,chemotherapy cycle and serum IL-1β,HBP,CAR were the influencing factors of secondary pulmonary Candida albicans infec-tion in patients with lung cancer during chemotherapy(P＜0.05).The area under the curve(AUC)of serumIL-1β,CAR and HBP in predicting pulmonary Candida albicans infection was 0.779,0.732 and 0.796,respec-tively.The AUC of the combination of the three was 0.931,and the sensitivity and specificity were 86.49％and 90.58％,respectively.The survival rate of lung cancer patients with high levels of IL-1β,CAR and HBP was sig-nificantly lower than that of patients with low levels of Il-1β,CAR and HBP(P＜0.05).Conclusion The in-crease of serum IL-1β,CAR and HBP levels in patients with lung cancer is related to secondary pulmonary Candida albicans infection during chemotherapy.Detection of these serum Il-1β,CAR and HBP levels is helpful to predict the risk of pulmonary Candida albicans infection and death.
