Application of MSCT Image Post-Processing Techniques in the Identification of Rib Fracture Malunion.

Objectives: To compare the application value of three image post-processing techniques volume rendering (VR), multiplanar reformation (MPR) and curved planar reformation (CPR) in the identification of rib fracture malunion.

Methods: The types and numbers of rib fracture malunion in 75 patients were recorded, and the sensitivity, specificity, accuracy and Youden index of VR, MPR and CPR in the diagnosis of rib fracture malunion were compared. Receiver operator characteristic (ROC) curve was drawn and area under the curve (AUC) was calculated, and the detection rates of three image post-processing techniques for different types of rib fracture malunion were compared.

Design of Faster R-CNN-Based Fault Detection Method for Subway Vehicles.

A substantial amount of maintenance and fault data is not properly utilized in the daily maintenance of pantographs in urban metro cars. Pantograph fault analysis can begin with three factors: the external environment, internal flaws, and joint behavior. Based on the analysis of pantograph fault types, corresponding measures are proposed in terms of pantograph fault handling and maintenance strategies, in order to provide safety guarantee for the safe and effective realization of rail transit vehicle speed-up and also provide reference for the maintenance and overhaul of pantographs.

Meta-Regression Analysis of the Long-Term Effects of Pallidal and Subthalamic Deep Brain Stimulation for the Treatment of Isolated Dystonia.

Objective: The globus pallidus internus (GPi) and subthalamic nucleus (STN) are therapeutic targets for deep brain stimulation (DBS) in the treatment of isolated dystonia. We conducted a meta-regression analysis on long-term studies of bilateral DBS in the GPi and STN to compare the relative effects of the 2 approaches.

Methods: We systematically searched the PubMed, Embase, and Cochrane Controlled Register of Trials databases to identify studies reporting the treatment outcomes of GPi DBS and STN DBS for isolated dystonia.

Predictive value of baseline C-reactive protein for periprocedural myocardial infraction of higher risk stratifications: A retrospective cohort clinical study.

Objective: It is controversial whether preprocedural elevated high sensitivity C-reactive protein (CRP) could increase the incidence of periprocedural myocardial infraction (PMI) of higher risk stratifications. The primary aim of this study was to evaluate whether preoperative elevated CRP level was related to the incidence of PMI in patients who underwent percutaneous coronary intervention (PCI).

Methods: A total of 4,426 patients [66 y (59, 75); 72.
