Objective: To compare pattern-pulse multifocal visual evoked potential (PPmfVEP) with pattern-reversal multifocal visual evoked potential (PRmfVEP), and to investigate the symmetry of mfVEP between both eyes in normal individuals.
Methods: The multifocal Vision Monitor was used to observe the mfVEP. T-test and ANOVA were used to analyze P1 wave, amplitude and signal noise ratios (SNR) of two mfVEPs.
Objective: To find an objective and accurate examination for evaluation of spinal cord injury (SCI) in forensic clinical medicine.
Methods: The onset latency of cortex, peak latency of N1, central motor conduction time (CMCT) and wave width of the abductor pollicis brevis and the anterior tibialis were calculated by transcranial magnetic stimulation-motor evoked potential (TMS-MEP). The data of 68 patients suffered from SCI including 23 cervical levels and 45 thoracolumbar levels were collected and compared with that of 30 normal controls.
[Analysis of forensic identification of traumatic macular hole in 16 cases].

Objective: To analyze and summarize the characteristics of traumatic macular hole and to discuss the key points and matters need attention in forensic identification.
Methods: Sixteen cases of traumatic macular hole were collected from Forensic Science Identification Center of China Medical University from 2004 to 2009 and analyzed.
Results: All of the 16 cases resulted from closed ocular contusion.
Objective: To study the characteristics of forensic identification cases involved with peripheral nerve injury, and to discuss how to apply the clinical information, forensic examination and neurophysiological testing.
Methods: One hundred and fifty-eight cases which were diagnosed peripheral nerve injury in clinic, were collected. Then the individual characteristics, injuries, identification results, exaggeration or camouflage were analysed.
Objective: To evaluate diagnostic value of spiral CT reconstruction in atlantoaxial injuries.
Methods: The images of 25 cases of spiral CT reconstruction were analyzed and compared with images of CT scan and X-ray.
Results: In 7 cases of odontoid process fracture, X-ray demonstrated 4 cases and CT demonstrated 5 cases, whereas the spiral CT reconstruction diagnosed 7 cases, which could display the displacement of fracture clearly.
Objective: To analyze the clinical characteristics of post-traumatic abortion and the relationship between trauma and abortion.
Methods: We collected and analyzed 23 cases of post-traumatic abortion encountered in the department of clinical forensic medicine, faculty of forensic medicine, China Medical University in recent years.
Results: All 23 post-traumatic abort inns were early abortions.
Objective: To evaluate the diagnostic value of somatosensory evoked potential(SEP) in lumbosacral disc herniation(LDH).
Methods: Posterior tibial nerve somatosensory evoked potential(PTNSEP) and dermatomal somatosensory evoked potential (DSEP) were recorded from 60 patients with radiculopathy caused by LDH and 30 healthy subjects.
Results: DSEP was abnormal in 56 cases (93.
