This study demonstrated that chewing gum can promote bowel function recovery in elderly patients after lumbar spinal surgery.

In patients with bone tumors of the proximal femur, endoprosthetic reconstruction can provide stable and durable biological reconstruction. However, it is difficult and time-consuming to accurately place the femoral component for an appropriate anteversion angle after large tumor resection. We propose a modified surgical technique for simplifying the implantation process and promoting the stability of the artificial joint. We retrospectively analyzed the clinical data of 28 patients undergoing endoprosthetic reconstruction at our center between 2009 and 2016. We used a traditional method (group A, n=11) and a modified surgical technique (group B, n=17) to determine the femoral anteversion angle during implantation of the femoral component. The modified surgical technique allowed more convenient and accurate implantation of the femoral components by externally rotating the shin at an angle of 15°. Surgical time and blood loss were designated as the primary outcomes, hospital stays, postoperative complicatimplications. Systemic lupus erythematosus (SLE) is an autoimmune disease. This study aims to analyze the value of procalcitonin (PCT), white blood cell count (WBC), and neutrophil-to-lymphocyte ratio (NLR) in the differential diagnosis of SLE with a bacterial infection.
