ABSTRACT
OBJECTIVE@#To investigate the clinical effect of anterior cervical Hybrid surgery in the treatment of cervical degenerative diseases (CDD) and observe the incidence of heterotopic ossification of disc replacement segment at 1 year after surgery.@*METHODS@#From January 2015 to April 2018, 35 patients who received anterior cervical hybrid surgery met the inclusion and exclusion criteria and the complete clinical follow up data were analyzed retrospectively. Complete imaging follow-up data were obtained from 24 patients. There were 15 males and 20 females, aged from 39 to 70(55.57±7.73) years old. The amount of bleeding was for 20 to 100 (40.29±18.39) ml, and the hospitalstay was for 4 to 28(11.03±4.63) days, and the follow-up time was(12.97±1.36) months. Clinical outcomes were assessed by the Tanaka Yasushi cervical spondylitis symptom scale 20 score (YT20), and Japanese Orthopaedic Association (JOA) score. The occurrence of heterotopic ossification after Hybrid surgery was evaluated by X-ray according to McAfee standard one year after operation. Patients with or without heterotopic ossificationwere divided into two groups and their clinical effects were compared.@*RESULTS@#At the final follow up, the mean YT20 score and JOA score were significantly higher than those before operation (P <0.05), and the average improvement rate of JOA was (70.66 ±0.44)%. One year after operation, the heterotopic ossification occurred in 10 of 24 segments, with incidence of 41.70%(10/24), including 29.20% in gradeⅠand 12.50% in gradeⅡ. The results of clinical efficacy comparison between patients with and without heterotopic ossification were as follows:there was no significant difference in JOA score before and after operation (@*CONCLUSION@#The short-term clinical effect of Hybrid surgery is satisfactory for cervical degenerative diseases, and the cause of heterotopic ossification still needs tobe further explored.

<p><b>OBJECTIVE</b>To compare the clinical effect between spinal card decompression combined with traditional Chinese medicine and simple spinal card decompression for cervical spondylotic myelopathy.</p><p><b>METHODS</b>From June 2012 to June 2015, 73 patients with cervical spondylotic myelopathy were treated, including 42 males and 31 females, aged from 29 to 73 years old with a mean of 50.9 years old. The patients were divided into the simple operation group (34 cases) and the operation combined with traditional Chinese medicine group(39 cases) according to the idea of themselves. The anterior discectomy or subtotal corpectomy with internal fixation or posterior simple open-door decompression with lateral mass screw fixation were performed in the patients. Among them, 39 cases were treated with traditional Chinese medicine after surgery. The Japanese orthopedic association (JOA) score of spinal cord function, the improvement rate of neural function, the neck dysfunction index (NDI) score and the governor vessel stasis syndrome score were compared between two groups preoperative and postoperative 1 week, 1 month and the final follow-up respectively. The internal fixation and the condition of spinal cord decompression were observed by CT, MRI and X-rays before and after operation.</p><p><b>RESULTS</b>All the operations were successful, no injuries such as dura mater, spinal cord and nerve root were found. All the wounds were healed without infection except one patient had a superficial infection. It was solved after intermittent debridement and anti-infective therapy. Hematoma occurred in 1 case, complicated with spinal cord compression, caused incomplete paralysis, and promptly performed the re-operation to remove the hematoma without any obvious sequelae. All the patients were followed up from 12 to 24 months, (14.6±0.8) months for simple operation group and (13.5±0.7) months for operation combined with traditional Chinese medicine group, and there was no significant difference(>0.05). The scores of JOA, NDI and the governor's vessel stasis syndrome in simple operation group were 8.31±3.15, 29.91±4.52, 6.58±1.31 before operation, and 10.21±2.58, 18.67±4.31, 8.24±1.18 one week after operation, and 11.38±2.85, 16.11±3.18, 8.91±2.11 one month after operation, and 12.21±3.12, 14.61±3.28, 9.12±1.56 at final follow-up, respectively; and in operation combined with traditional Chinese medicine group were 8.29±3.47, 30.83±4.14, 6.38±1.81before operation, and 10.48±2.39, 17.59±5.14, 8.33±1.57 one week after operation, and 12.14±3.12, 13.14±3.21, 9.55±2.49 one month after operation, and 13.85±3.34, 12.11±2.51, 10.33±1.95 at final follow-up, respectively. Postoperative JOA , NDI, and the governor vessel stasis syndrome score of two groups were significantly higher than preoperativee(<0.05). There was no significant difference in JOA, NDI, and the governor vessel stasis syndrome score between two groups one week after operation (>0.05). The above items in operation combined with traditional Chinese medicine group was better than that of simple operation group one month and final follow-up after operation (<0.05). The improvement rate of neural function in simple operation group was (67.59±10.78)%, and in operation combined traditional Chinese medicine group was (66.88±12.15)%, there was no significant difference between two groups(>0.05). There were no complications such as internal fixation failure or re-dislocation of atlas by postoperative CT, MRI and X-rays examination.</p><p><b>CONCLUSIONS</b>Spinal card decompression for the treatment of cervical spondylotic myelopathy can extend the spinal canal, relieve the compression of nerve, achieve the deoppilation of governor vessel, the regulation of qi and blood, the restore of Yangqi, combined with traditional Chinese medicine of activating blood removing stasis, warming yang and activating meridians, reinforcing liver benefiting kidney, which may obtain better clinical effect.</p>
ABSTRACT
<p><b>OBJECTIVE</b>To explore the effect and underlying mechanism of decompression(DE)combined with Governor Vessel(GV)electro-acupuncture(EA) on rats with acute severe upper cervical spinal cord compression injury.</p><p><b>METHODS</b>Thirty SPF rats were randomly divided into 5 groups(control group A, B and experiment group C, D, E), 6 rats in each group. The model of acute severe upper cervical spinal cord compression injury were made by forcing a balloon catheter put in atlas pillow clearance. The group A was blank one, the group B put balloon catheter in atlas pillow clearance without forcing, and the group C, D, E sustained compressed for 48 h. The group C received electric acupuncture intervention, selecting the Baihui and Dazhui point, having the continuous wave and frequency of 2 Hz, with the treatment time of 15 min and continuous treatment for 14 d; the group D received methylprednisolone intervention, injected by caudal vein; the group E did not received any intervention again. The arterial blood and injured spinal cord tissue of all the rats were obtained after 14 days' treatment, and BBB score was used to evaluate the change of each group hind limbs motor function, the contents of platelet activating factor(PAF) in injured spinal cord tissue and blood serum were assess by ELISA method; the Caspase-9 expression for each group after 14 days' treatment was assess by Western blot method.</p><p><b>RESULTS</b>BBB scores were(21.000±0.000) points at the 6 time points, that was, 1 h, 48 h after forcing in control group, 24 h, 3 d, 7 d, 14 d after treating in experiment group; the score of experimental groups (group C, D, E) were always lower than control groups(group A, B); compared with group E, group C and D were significantly higher(<0.05); and there was no significant difference between group C and group D(>0.05). The results of PAF by ELISA method to measure:the concentration of serum PAF, there was no statistical difference among group A, B, D, E (>0.05), group C was lower than the other groups (<0.05); the concentration of tissue PAF, there was no significant difference between group A and group B(>0.05), group D was significantly higher than that of group A, B, and C(<0.05), group E was the highest one than that of the other groups(<0.05). Western blot med tests showed that the Caspase-9 protein expression in group A and B was similar (>0.05), group C was higher than that of group A and B(<0.05), group D was higher than group A, B and C(<0.05), group E was the highest than that of group A, B, C and D (<0.05).</p><p><b>CONCLUSIONS</b>Decompression and Governor Vessel electro-acupuncture on acute severe upper cervical spinal cord compression injury had a better effect compare with decompression and methylprednisolone or simple decompression only, its mechanism may be related to lower the PAF levels and downregulating Caspase-9 protein expression in spinal injury tissue.</p>
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effect and mechanism of Buyanghuanwu decoction on platelet activating factor expression in spinal cord tissue of model of acute upper cervical spinal cord injury in rats.</p><p><b>METHODS</b>Sixty SPF grade 3-month-old female Wistar rats were randomly divided into sham operation group, model group, methylprednisolone group and Buyanghuanwu decoction (Traditional Chinese Medicine group, TCM), with 15 rats in each group. The first day after the modeling, the methylprednisolone group were treated by injection of the tail vein for a total of 24 h, the first dose of 30 mg/kg, followed by a dose of 5.4 mg/kg·h, and 1 time per 4 h. The traditional Chinese medicine group was prepared with a medium dose of Buyanghuanwu decoction granules which were prepared into a solution containing 2 g/ml of granules, 3.5 g/kg per day gavage, was equivalent to 1 time the amount of adult consumption. The model group and the sham operation group were given equal volume of normal saline for 2 times a day for 2 weeks. The recovery of nerve function was evaluated by BBB classification at 1, 3, 7, 14 days after treatment. The expression of PAF in the segment of spinal cord injury was detected by double antibody sandwich (ELISA) method at 1, 7, and 14 d postoperatively.</p><p><b>RESULTS</b>At the first day after treatment, BBB score in model, TCM and methylprednisolone groups were lower than that of sham operation group(<0.01), but there was no difference among the three groups(>0.05). At 7, 14 days afer treatment, BBB score in TCM and methylprednisolone groups were higher than that of model group significantly(<0.01); but there were no significant difference between TCM group and methylprednisolone group(>0.05). PAF expression in TCM group and methylprednisolone group were lower than that of model group at 7, 14 day afer treatment significantly (<0.05); but there were no significant difference between TCM group and methylprednisolone group (>0.05).</p><p><b>CONCLUSIONS</b>Buyanghuanwu decoction treatment after acute upper cervical spinal cord injury can significantly improve locomotor recovery by inhibiting the expression of PAF.</p>
