ABSTRACT

@#Objective To observe the effect sling exercise therapy (SET) and Tuina on radicular cervical spondylosis. Methods From August, 2015 to December, 2016, 72 patients with radicular cervical spondylosis were randomly divided into control group (n = 36) and trial group (n = 36), who accepted traction and SET+Tuina, respectively, for four weeks. They were measured F-wave conduction velocity with electromyogram from median nerve and ulnar nerve, somatosensory evoked potential (SEP), and current perception threshold (CPT) before and after treatment. The clinical ratio of improvement was calculated. Results The ratio of improvement was 83.33% in the trial group more than 58.33% in the control group (Z = 2.093, P < 0.05). F-wave conduction velocity increased in both groups after treatment (t > 12.059, P < 0.001), and increased more in the trial group than in the control group (t > 3.266, P < 0.01); while the latency of SEP decreased in N9 and N13 in both groups (t > 7.061, P < 0.001), and decreased more in the trial group than in the control group (t > 8.033, P < 0.001); the grade of CPT decreased in both groups (t > 8.895, P < 0.001), and decreased more in the trial group than in the control group (t = 8.913, P < 0.001). Conclusion The combination of SET and Tuina can promote the repair of nerve conduction of cervical spondylotic radiculopathy.

ABSTRACT

BACKGROUND: Many factors affect the outcome of olfactory ensheathing cell transplantation for obsolete spinal cord injury, such as the time of injury, segment and sex. The best time to do olfactory ensheathing cell transplantation is unknown up to now. OBJECTIVE: To investigate the influence of time windows of olfactory ensheathing cell transplantation on the recovery of motion and sensation function in spinal cord injury patients. DESIGN: Self-control observation. SETTING: Department of Neurosurgery, Taian Disabled Soldier's Hospital. PARTICIPANTS: 135 patients with spinal cord injury were enrolled at the Department of Spinal Cord Surgery, Taian Disabled Soldier's Hospital of Shandong Province from June 2004 to June 2007, including 121 males and 14 females, aged 7-59 years, averagely 36 years. Duration of spinal cord injury included 0-6 months in 21 cases, 7 months-2 years in 71 cases and over 2 years in 43 cases. These patients or their guardians signed an informed consent of the cell transplantation. The experimental procedures were accorded with the rules of Ministry of Health of China (No. 91-006) and approved by the Taian Disabled Soldier's Hospital of Shandong Province. METHODS: ①Olfactory bulbs of aborted fetus were digested into single olfactory ensheathing cells, and then cultured for 7-15 days. Parturients signed the informed consent. This study was approved by the Hospital Ethical Committee. ②After general anesthesia, olfactory ensheathing cell suspension was implanted into the corresponding region by the multi-targeted injection with a microscope. According to the injury condition, targets generally located in upper or lower injured region and left or right normal spinal cord. The amount of targets depends on the size of the injured region. About 1 000 000 units of cells were injected into each target, about 50 μL of suspension, at 2×1010 L-1, 2-5 targets. ③American Spinal Injury Association impairment scale was used to assess the motion and sensation function in spinal cord injury patients before transplantation and 2-8 weeks after transplantation. MAIN OUTCOME MEASURES: Scores on American Spinal Injury Association impairment scale. RESULTS: 135 spinal cord injury patients were involved in the result analysis. Motion and sensation function was improved in spinal cord injury patients at different time windows compared with that before transplantation (P < 0.01). There was no significant difference in scores on motion and sensation function and the increased degree of the score at different time windows after transplantation (P > 0.05).CONCLUSION: Olfactory ensheathing cell transplantation can promote the recovery of nerve function in spinal cord injury patients, without the difference in time windows.

ABSTRACT

BACKGROUND: Animal experimental studies have confirmed that cell transplantation, neurotrophic factor infusion or transplantation as well as other methods can alter the local environment of injured spinal cord and promote its partial function recovery.OBJECTIVE: This study aimed to assess the clinical efficacy of olfactory ensheathing cell transplantation for the treatment of the sequel of myelitis, and to explore whether it would promote the recovery of the spinal cord function.DESIGN: A non-randomized self-control study.SETTING: Ward of Second Department of Surgery of Taian Disabled Soldiers Hospital of Shandong Province.PARTICIPANTS: Thirty-two patients with obsolete myelitis, who come from all over China and suffered from disease for 0.5 to 7 years, admitted to our hospital between June 2004 and July 2007 were recruited in this study. The involved patients, including 21 males and 11 females, were aged 5-48 years. Their neurological functions were not obviously improved after various conventional treatments and limb function exercise. Meanwhile, various sensorimotors and autonomic nerve functional impairments were left. Among the patients, 18 suffered from acute viral myelitis, 8 from acute purulent myelitis and 6 from tuberculous myelitis. After onset, they were all given large doses of radiosonde,dexamethasone, anti-inflammatory and immunomodulatory drugs and various neurotrophic drugs. Twenty-six patients presented complete injury and six patients incomplete injury. Informed consent of treatment was obtained from each patient. The therapeutic protocol was approved by the Ethics Committee of the hospital. Embryonic olfactory bulbs were harvested from aborted embryo, which was donated voluntarily by the patients or their relatives.METHODS: Cells were isolated from embryonic olfactory bulbs, cultured and purified for 7 to 14 days, and finally they were digested into single-cell suspension. Under the surgical miscroscope, the cells were transplanted onto the regions which were above or below the spinal cord injury site. Two weeks to 2 months postoperatively, neurological function of spinal cord was assessed by using the American Spinal Injury Association (ASIA) Scoring Standard formulated in 2000, and was compared to pre-operation function.MAIN OUTCOME MEASURES: ①Sensory function change. ②Motor function change.RESULTS: Half a year to 2 years after olfactory ensheathing cell transplantation, the sensory and motor functions of 32 patients were all obviously improved (motor function: 55.72±10.50 vs. 51.53±13.41; light touch:69.53±11.68 vs.63.06±15.98; pain sense: 69.50±12.20 vs. 64.03±15.0, all P < 0.01 ).CONCLUSION: Olfactory ensheathing cell transplantation can help to promote the neurological function recovery of patients with the sequel of myelitis. However, its long-term curative effect needs to be further investigated.

ABSTRACT

BACKGROUND: Changing the local environment of spinal injury promotes the repair and regeneration of injured nerve and recovery of partial nervous function of spinal cord. Transplantation of olfactory ensheathing cells can improve the local internal environment of injured spinal cord.OBJECTIVE: To probe into the effect and safety of transplantation of olfactory ensheathing cells on functional repair of spinal cord and nerve in patients with obsolete spinal injury DESIGN: Self-control experiment.SETTING: Wards of the Department of Surgery, Taian Rongjun Hospital of Shandong Province.PARTICIPANTS: Totally 48 patients admitted for obsolete spinal injury in the Department of Surgery, Taian Rongjun Hospital, between June 2004 and July 2005 were recruited. There were 39 males and 9 females, aged 7 to 59 years with the mean of 36 years.METHODS: ①Cell culture: Olfactory bulb of aborted fetus was digested into single olfactory ensheathing cells, which were then cultured and puri fied for 1 to 2 weeks, and finally made into single cell suspension. ②Operation and cell transplantation: Under general anesthesia, the purified single cell suspension (about 0.05-0.20 mL) of olfactory ensheathing cells was injected into the corresponding spinal injury site through multiple points with home-made syringe of 0.45 mm in diameter. Stitches were taken out at postoperative 10 to 14 days. ③Evaluation of spinal function: Injury Scoring Standard made by American Spinal Injury Association (ASIA) was used for scoring, comparison and statistical analysis at postoperative 1 day and 2 weeks to 2 months. ④Spinal function of 48 patients was observed or followed up through telephone at postoperative 3 weeks to 1 year.MAIN OUTCOME MEASURES: Changes of postoperative sensory function of the patients. Changes of postoperative motor function of the patients. Changes of postoperative automatic nervous system of the patients.RESULTS: ①All the 48 patients had improvement in spinal function, and continued improved tendency was found in the observation and follow-up through telephone at postoperative 3 weeks to 1 year. ②Scoring by ASIA for sensory function was higher after operation than before operation (touch sensation: 56.9, 51.2, P < 0.01; pain sensation: 55.2, 48.3, P < 0.01). Sensory function was improved obviously at the lower shift of sensory level,generally more than 2 segments. ③Scoring by ASIA for motor function was higher after operation than before operation (44.8, 40.7, P < 0.01), but the improvement was slow. ④Scoring by ASIA for automatic nervous system was higher after operation than before operation (18.0, 14.5, P < 0.01); diaphoresis, increased enterokinesia and other automatic nervous system improved earliest.CONCLUSION: Transplantation of olfactory ensheathing cells promotes the spinal and neurofunctional recovery of patients with malignant spinal injury, and the therapeutic method is safe.
