[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.

[Surgical technique and early clinical outcomes of direct anterior approach to total hip arthroplasty].
To describe the surgical technique of direct anterior approach to total hip arthroplasty and to report the early clinical outcomes. ⋯ Direct anterior approach to total hip arthroplasty allows accurate and reproducible cup orientation positioning and leg length restoration and decreases the risk of postoperative dislocation, which is helpful for early rapid postoperative recovery.

Case Reports[One of the pitfalls in the surgical treatment of maisonneuve fractures: a case report].
There exist controversies in the surgical treatment of maisonneuve injury with regard to reduction and fixation of syndesmosis and management of proximal fibular fracture. It is very important for the orthopaedic surgeons to learn more techniques and avoid pitfalls from clinical practice. We summarized the clinical data of 1 failed case, a 20-year-old girl with big body weight who underwent a primary surgery for the treatment of maisonneuve fracture with minimally invasive reduction and fixation of ankle syndesmosis and posterior malleolus and open reduction and internal fixation of medial malleolus, then a revision surgery for the treatment of iatrogenic syndesmotic malreduction with open reduction and re-stabilization of ankle syndesmosis supplemented with open reduction and internal fixation of proximal fibular facture. ⋯ Attention should be paid to the fact that an obliquely placed clamp for closed reduction of diastasis of ankle syndesmosis could result in syndesmotic malreduction. The worsened alignment of the fracture end of proximal fibula observed by intraoperative fluoroscopy may alert surgeons to syndesmotic malreduction. Partial exposure of syndesmosis and anatomical reduction and fixation of proximal fibular fracture may be useful measurres to avoid malreduction of ankle syndesmosis in the surgical treatment of maisonneuve injury in some patient, especially the patient with critically destabilized ankle.
