[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.

Randomized Controlled Trial[Comparison between flexible laryngeal mask airway and reinforced tracheal tube used for lumbar vertebral surgery in prone position].
To estimate the safety and feasibility of flexible laryngeal mask airway (FLMA) for lumbar vertebral surgery in prone position. ⋯ For suitable patients, FLMA can be used in mechanical ventilation forlumbar vertebral surgery in prone position with more stable circulation and less respiratory complications than RTT. Further clinical validation is needed for the safety of FLMA.

[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.

[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.
