  • OLFACTORY ENSHEATHING CELLS TRANSPLANTATION FOR CENTRAL NERVOUS SYSTEM DISEASES IN 1 255 PATIENTS

    Objective To analyze the therapeutic effect of olfactory ensheathing cells (OECs) transplantation for central nervous system diseases. Methods Between November 2001 and January 2008, 1 255 participants with central nervous system diseases were enrolled in this cl inical study for fetal OECs transplantation. There were 928 males and 327 femalesaged 1.2-87 (mean 40) years. The course of disease was (4.52 ± 4.67) years. Among them, 656 participants suffered from chronic spinal cord injury (SCI), 457 amyotrophic lateral sclerosis (ALS), 68 cerebral palsy (CP), 20 multiple sclerosis (MS), 11 the sequelae of stoke, 10 ataxia, and 33 residual diseases. The participants came from 71 countries or regions. Accidentally abortional fetal olfactory bulbs were donated voluntarily and were cultured for 2 weeks, then were transplanted. Results One thousand one hundred and twenty-eight cases were followed up for 2-8 weeks (mean 4 weeks) to obtain integrated data. Among them, the neurological functional amel ioration was noticed in 994 participants with the overall short-term improvement rate of 88.12%. Seventy-six patients experienced the various perioperative compl ications with the incidence rate of 6.74%. One hundred and twenty patients with SCI received over 1 year follow-up. And according to ASIA assessment, motor scores increased from (39.82 ± 20.25) to (44.55 ± 18.99) points, l ight touch scores from (51.56 ± 25.89) to (59.81 ± 27.72) points, pain scores from (50.36 ± 27.44) to (57.09 ± 28.51) points for foreign patients (P lt; 0.05); motor scores increased from (40.52 ± 20.80) to (46.45 ± 20.35) points, l ight touch scores from (55.64 ± 26.32) to (68.64 ± 25.89) points, pain scores from (57.05 ± 26.00) to (66.13 ± 24.29) points for good rehabil itation Chinese patients (overall P lt; 0.05); motor scores from (37.03 ± 18.52) to (38.03 ± 18.50 points (P lt;0.05), l ight touch scores from (45.88 ± 22.56) to (46.63 ± 23.09) points (P gt; 0.05), pain scores from (45.25 ± 23.68) to (45.28 ± 23.63) points (P gt; 0.05) for poor rehabil itation Chinese patients. Compared foreign patients and good rehabil itation Chinese patients with poor rehabil itation Chinese patients, difference in score change was remarkable (P lt; 0.05). One hundred and six cases of ALS, 32 CP, 8 MS, 7 ataxia, and 2 stroke sequelae were followed up for 3-48, 3-36, 2-20, 7-17, 6 and 24 months, One hundred and six cases of respectively. Majority of them (113/155, 72.9%)were benefited from OECs transplantation. Conclusion OECs transplantation into brain and spinal cord is feasible and safe . The therapeutic strategy is valuable treatment for such central nervous system diseases such as chronic SCI, ALS, CP and stroke sequelae and can improve the patients’ neurological functions and/or decrease the progressive deterioration.

  • INTRODUCTION OF AMYOTROPHIC LATERAL SCLEROSIS SELF-ASSESSMENT SCALE

    Objective To introduce a new functional self-assessment scale of amyotrophic lateral sclerosis (ALS). Methods By comparing current different ALS functional scales and combining relative cl inical experience and numeric pain intensity scale, ALS self-assessment scale was set down by International Association of Neural Restoration. Results ALS self-assessment scale included 3 categories with 18 items, adopting 10 points grading system, namely 10 was defined as the normal, 0 as the worst, and the total scores was 180. This scale included: ① Bulbus medullae function: speech, swallowing, sal ivation, and tongue extension. ② Limbs function: left arm movement, left hand movement, right arm movement, right hand movement, left leg movement, right leg movement, trunk movement, head-up, walking, and cl imbing stairs. ③ Others: breathing, muscular tone, pain, and muscle discomfort. Conclusion ALS self-assessment scale is specifically designed for ASL patients. It can evaluate patient’s function comprehensively and is simple and convenient, consuming less time.

  • Short-term Outcome of Olfactory Ensheathing Cells Transplantation for Treatment of Amyotrophic Lateral Sclerosis

    Objective To determine whether transplanting olfactory ensheathing cells (OECs) is effective in controlling or reversing the deterioration caused by amyotrophic lateral sclerosis (ALS). Methods Between February 2003 and April 2006, 327 patients (241 males and 86 females) with probable or definite ALS (diagnosed according to the El Escorial criteria) received the OECs transplantation. Their ages ranged from 20 to 84 years (51.6±11.1 years). The duration of symptoms before surgical treatment was 4-8 months to 13 years (2.9±2.0 years). OECs were cultured and injected into pathological regions of the spinal cord and/or bilateral corona radiata of the brain; the patients were divided into three groups, group A (cord only,n=29), group B (cord and brain,n=6), and group C (brain only,n=292) based on the transplant sites. Results The patient’s neurological function was assessed both before and at 4 weeks after transplantation by using the Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS) of the ALS CNTF Treatment Study (ACTS). The scores were increased from 17.2±8.6 preoperation to 20.1±9.7 postoperation in group A (P<0.05),from 24.2±6.8to 25.7±6.6 (P>0.05) in group B, and from 20.3±8.6 to 22.0±9.4 (P<0.001) in group C.There were no significant difference in increased ALSFRS scores among the threegroups (P>0.05). The total improvement rate of neurological function was 77.1% (252/327). The result of electromyographic examination showed that spontaneouspotential diminished and/or disappeared, the amplitude of the motor unit actionpotential decreased remarkably and the numbers of motor unit action potential greatly increased in 261 cases (79.8%). Sixteen patients (4.9%) experienced thevarious complications including headache, shortterm fever, seizure attack, central nerve system infection, pneumonia, respiratory failure, urinary tract infection, heart failure, and possible pulmonary embolism; of them, there were 4 deaths(1.2%). Conclusion These preliminary results suggest that the OECs transplantation is effective in controlling or reversing the physiological deterioration caused by ALS.
