Neural Mechanism Underlying Task-Specific Enhancement of Motor Learning by Concurrent Transcranial Direct Current Stimulation.

The optimal protocol for neuromodulation by transcranial direct current stimulation (tDCS) remains unclear. Using the rotarod paradigm, we found that mouse motor learning was enhanced by anodal tDCS (3.2 mA/cm) during but not before or after the performance of a task.

Expression of HGF/c-Met is dynamically regulated in the dorsal root ganglions and spinal cord of adult rats following sciatic nerve ligation.

Hepatocyte growth factor (HGF) and its receptor c-Met play pivotal roles in post-traumatic regeneration of the nervous system. However, following peripheral nerve injury, the role and regulation of the HGF/c-Met system is less clear. Therefore, using a sciatic nerve ligation (SNL) model, spatiotemporal changes in HGF and c-Met expression were detected in the dorsal root ganglions (DRGs) and lumbar spinal cords of adult rats.

[Optimization of antibiotics in combination].

Objective: To evaluate the antibacterial activity of Ciprofloxacin, Amikacin in combination with beta-lactams against Pseudomonas aeruginosa strains in vitro, to optimize treatment regime for antibiotics on the basis of pharmacokinetics (PK)/pharmacodynamics (PD) and drug sensitivity tests. Methods With checkerboard titration method, the minimal inhibitory concentrations (MIC) of a combination of antibiotics in different concentrations for 33 clinically isolated Pseudomonas aeruginosa strains were determined by broth dilution. Fractional inhibitory concentrations (FIC) were calculated for judging synergic effect of antibiotics.

[Applied anatomy of inferior epigastric artery in coronary artery bypass grafting].

Objective: To measure the inferior epigastric artery(IEA),coronary artery and arterial bridge to supply the anatomic and hemodynamic data of IEA in coronary artery bypass grafting for clinicians.

Methods: Anatomic method was adopted to measure the length of IEA, arterial bridge, the outer diameter of IEA and coronary arteries. Colour doppler ultrasound instrument was adopted to measure the caliber and the blood flow rate of IEA and coronary artery.

[Microscopic study on skin and soft tissue after repeated expansion].

Objective: The study was to evaluate the microscopic changes on skin and soft tissue after repeated expansion for clinical work.

Methods: Six little pigs were divideded as: conventional expansion group, repeated expansion group, and blank control group. Histologic, ultrastructure and bFGF of the skin were observed and measured in each group after samples had been made.
