[Clinical comparison of polymethylmethacrylate and bone cement in the treatment of osteoporotic vertebral compression fractures: a retrospective study].
To analyze the outcomes of patients with osteoporotic vertebral compression fractures treated with polymethylmethacrylate (PMMA) and GeneX bone cement in percutaneous kyphoplasty and to provide guidance in selecting the vertebral filling material for this procedure. ⋯ GeneX bone cement is similar to PMMA in terms of postoperative pain relief. As the filling material in percutaneous kyphoplasty, it is effective at maintaining vertebral height, quickly improves strength and stiffness of the vertebral body and has fewer complications. However, it is not satisfactory in maintaining long-term postoperative vertebral height. GeneX bone cement can be used as the filling material for patients with osteoporotic vertebral compression fractures in percutaneous kyphoplasty. Patients with severe osteoporosis and vertebral compression should be treated with standardized osteoporosis treatment and should try to avoid early postoperative walking exercises. Sustained vertebral filling materials, such as PMMA, are more suitable for such patients. Research into better biodegradable materials is still needed.

[Clinical research on robot-assisted percutaneous pelvic and acetabular screws surgery].
To evaluate the security and efficiency of a surgical robotic assisted percutaneous screw fixation for the treatment of pelvic and acetabular fractures. ⋯ Surgical robots are suitable for robot-assisted percutaneous screw fixation in pelvic and acetabular fractures. Robot-assisted treatment of pelvic and acetabular fractures has significant advantages over manual operations including high accuracy, small perspective radiation, safety and efficiency.

[Efficacy of transforaminal endoscopic nerve root decompression in the treatment of degenerative lumbar spinal stenosis].
To evaluate the feasibility of transforaminal endoscopic nerve root decompression for degenerative lumbar spinal stenosis (DLSS). ⋯ We can apply transforaminal endoscopic decompression for the patients of lumbar spinal stenosis who have unilateral nerve root irritation. Patients with transforaminal endoscopic decompression can get less surgical trauma, quick recovery and obtain good short-term outcome.

[Influences of repeated propofol anesthesia on hippocampal apoptosis and long-term learning and memory abilities of neonatal rats].
To investigate the influences of repeated propofol anesthesia on the hippocampal apoptosis and the long-term learning and memory abilities of neonatal rats. ⋯ Repeated propofol anesthesia may destroy long-term learning and memory abilities by inducing apoptosis of hippocampal neurons in neonatal rats, while single dose of propofol has no obvious effect on the hippocampal apoptosis and long-term learning and memory of neonatal rats.
