The specific pathophysiological mechanism of chronic thoracolumbar cord injury has not yet been elucidated. The purpose of this study was to improve animal models of chronic thoracolumbar cord compression using the progressive screw. A custom-designed flat plastic screw was implanted in the spinal cord between thoracic vertebrae 12 and lumbar 1 of rats. The screw was tightened one complete turn（0.5 mm） every 7 days for 4 weeks to create different levels of chronic spinal cord compression. Following insertion of the screw, there was a significant decline in motor function of the hind limbs, and severe stenosis of micro-computed tomography parameters in the spinal cord. Cortical somatosensory evoked potential amplitudes were reduced remarkably, and latencies were prolonged at 30 minutes after surgery. The loss of motor neurons in the gray matter was marked. Demyelination and cavitation were observed in the white matter. An appropriate rat model of chronic thoracolumbar cord compression was successfully created using the progressive screw compression method, which simulated spinal cord compression injury.展开更多

Methods: 66 cases of acute lumbar vertebral articular dyskinesia were randomly divided into acupuncture plus manual reposition group (treatment group, n=33) and routine manual reposition group (control group, n=33). Yaotong point was punctured, when, the patient was asked to move his or her waist simultaneously. Results: After one session of treatment, of the two 33 cases in treatment and control groups, 28 (84.85%) and 20 (60.61%) were cured, 4 (12.12%) and 9 (27.27%) were improved, and 1 (3.03%) and 4 (12.12%) failed in the treatment. The therapeutic effect of treatment group was significantly superior to that of control group (P<0.05). Conclusion: Acupuncture combined with manual reposition is apparently superior to simple routine manual reposition in relieving acute lumbar vertebral articular dyskinesia.展开更多

It is difficult to identify the main focus and responsible segment, and it is also difficult to select the sequence of staging surgery.
