Methods From March, 2009 to July, 2010, 16 cases with chronic cervical cord injury underwent spinal dura mater incision and unilateral open-door laminoplasty with internal screw fixation. Nerve functions of preand postoperation were evaluated by Frankel classification and the Japanese Orthopaedic Association (JOA) scale. The improvement rate of JOA score at the indicated time was recorded. Results Postoperative Frankel classification rating of 16 patients improved obviously. JOA scores at the 1st month, 3rd month, 6th month, and 12th month after surgery were 7.9±2.3, 8.5±1.6, 8.9±2.1, and 12.4±2.5, respectively, and significantly increased compared with that prior to surgery (5.5±0.6). At the end of follow-up period, JOA score was significantly higher than that of pre-treatment (P<0.05). The recovery was relatively rapid during the first 3 months following the surgery, then entered a platform period. Conclusion It is effective for patients with dated spinal cord injury to undergo spinal decompression and laminoplasty.展开更多
Effects of electroacupuncture (EA) and routine acupuncture with twirling reinforcing and reducing manipulation of the needle (RA) both at Zusanli point (St 36) on volume of microcirculatory blood flow in the cerebral ...Effects of electroacupuncture (EA) and routine acupuncture with twirling reinforcing and reducing manipulation of the needle (RA) both at Zusanli point (St 36) on volume of microcirculatory blood flow in the cerebral pia mater were observed by fenestration of the cranial bone and laser Doppler microcirculatory blood flow analyser. Results showed that both RA and EA could increase the volume of microcirculatory blood flow in the cerebral pia mater; and that the increase in the EA group was superior to that in RA group. This suggests that a moderate and effective stimulation is a key to the production of a regulative effect on the organism.展开更多
