[Drainage characteristic of the brain interstitial fluid detected by using fluorescence and magnetic tracer method].
Compare the results of molecular diffusion and mass flow in the interstitial space(ISS) displayed by using optical and magnetic probes and study partitioned drainage of the brain interstitial fluid (ISF). ⋯ LSCM imaging technology confirmed partitioned drainage of the brain ISF found by MRI tracer-based method and provided technology and method validation for MRI tracer-based method. LSCM imaging technology with higher contrast and resolution, therefore more sophisticated partitioned drainage of the brain interstitial fluid were got.

Randomized Controlled Trial[Comparison of the effects of total hip arthroplasty via direct anterior approach and posterolateral piriformis-sparing approach].
To compare the clinical effects of direct anterior approach (DAA) and posterolateral piriformis-sparing approach (Mis-PLA) for minimally invasive surgery of total hip arthroplasty. ⋯ Total hip arthroplasty through either DAA or Mis-PLA approaches could result in very satisfactory clinical effect. Comparing with DAA, Mis-PLA requires less operation time, shorter learning curve,which indicates that it is a relatively safer approach. The advantages of total hip arthroplasty through direct anterior approach lie in less positional limitation in the early stage of postoperative period, as well as a faster recovery of hip function.

[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.

[Clinical evaluation of in-plane ultrasound-guided thoracic paravertebral block using laterally intercostal approach].
To evaluate the feasibility and success rate of in-plane ultrasound-guided paravertebral block using laterally intercostal approach. ⋯ Thoracic paravertebral block using laterally intercostal approach is feasible, which has high success rate of block and low rate of complications.
