Objective:To identify risk factors for cement leakage in percutaneous vertebroplasty (PVP) for Kümmell disease.Methods:A total of 309 patients (351 levels) with Kümmell disease who underwent PVP between November 2015 and June 2019 were retrospectively reviewed. Age, gender, time of symptom onset, staging of Kümmell disease, fracture site(thoracic, lumbar), cortical disruption, type of fracture (wedge, biconcave, crush), fracture severity (mild, moderate, severe), intrusion of posterior wall, basivertebral foramen, puncture approach (unilateral, bilateral), cement distribution pattern (lumped, spongy), cement volume, cement leakage (yes, no) and cement leakage type were recorded. Cement leakage was classified into three types: through the basivertebral vein, through the cortical defect, and through the segmental vein. The data was analyzed by univariate and multivariate analysis to determine related factors of cement leakage in general and each type.Results:The rate of overall leakage was 65.8% (231/351). The leakage rate of basivertebral vein type, cortical defect type, and segmental vein type was 21.4% (75/351), 37.6% (132/351) and 22.8% (80/351), respectively. Multivariate analysis showed that three significant factors related to leakage in general were cortical disruption, basivertebral foramen and cement distribution pattern. Significant factors related to basivertebral vein type leakage were basivertebral foramen and cement distribution pattern. Significant factors related to cortical defect type leakage were cortical disruption and cement distribution pattern. Significant factors related to segmental vein type leakage were basivertebral foramen, cement distribution pattern, cement volume and fracture site.Conclusion:Risk factors of cement leakage in PVP for Kümmell disease include cortical disruption, basivertebral foramen and cement distribution pattern.

Focused on the world-wide issue of improving the accuracy of emotion recognition, this paper proposes an electroencephalogram (EEG) signal feature extraction algorithm based on wavelet packet energy entropy and auto-regressive (AR) model. The auto-regressive process can be approached to EEG signal as much as possible, and provide a wealth of spectral information with few parameters. The wavelet packet entropy reflects the spectral energy distribution of the signal in each frequency band. Combination of them gives a better reflect of the energy characteristics of EEG signals. Feature extraction and fusion are implemented based on kernel principal component analysis. Six emotional states from a public multimodal database for emotion analysis using physiological signals (DEAP) are recognized. The results show that the recognition accuracy of the proposed algorithm is more than 90%, and the highest recognition accuracy is 99.33%. It indicates that this algorithm can extract the feature of EEG emotion well, and it is a kind of effective emotion feature extraction algorithm, providing support to emotion recognition.

In order to enhance the anticoagulant properties of decellularized biological materials as scaffolds for tissue engineering research via heparinized process, the decellularized porcine liver scaffolds were respectively immobilized with heparin through layer-by-layer self-assembly technique (LBL), multi-point attachment (MPA) or end-point attachment (EPA). The effects of heparinization and anticoagulant ability were tested. The results showed that the three different scaffolds had different contents of heparin. All the three kinds of heparinized scaffolds gained better performance of anticoagulant than that of the control scaffold. The thrombin time (TT), prothrombin time (PT) and activated partial thromboplastin time (APTT) of EPA scaffold group were longest in all the groups, and all the three times exceeded the measurement limit of the instrument. In addition, EPA scaffolds group showed the shortest prepared time, the slowest speed for heparin release and the longest recalcification time among all the groups. The decellularized biological materials for tissue engineering acquire the best effect of anticoagulant ability in vitro via EPA heparinized technique.
