This study includes three aspects:(1) we have reported some novel or rare mutations of SOD1(Cu/Zn superoxide dismutase) gene in Chinese families of ALS/MND,and found quite different features from Western patients in polymorphisms with some candidate genes such as vascular endothelial growth factor(VEGF) in sporadic ALS/MND in China.Meanwhile,we have so for established a complete clinical database with more than 1 200 cases;(2) we have established some neurophysiologic techniques of diagnosis and differential diagnosis at early-stage for ALS/MND,which include trigemino-cervical response,sternocleidomastoid and rectus electromyography,contact heat evoked potentials,and motor unit number estimate;(3) we have attempted some experimental and clinical treatments for ALS/MND,which include gene and stem cell therapies in animal models,and a pilot clinical trial of granulocyte colony stimulating factor(G-CSF) for ALS/MND patients(NCT00397423).Abstract:SUMM ARY This study includes three aspects:(1) we have reported some novel or rare mutations of SOD1(Cu /Zn superoxide d ismutase) gene in Chinese fam ilies ofALS /MND,and found quite d ifferent features from W estern patients in polymorphisms with some cand idate genes such as vascular endothelial growth factor(VEGF) in sporad ic ALS /MND in China.Meanwhile,we have so for established a com-plete clinical database with more than 1 200 cases;(2) we have established some neurophysiologic tech-niques of d iagnosis and d ifferential d iagnosis at early-stage forALS /MND,which include trigem ino-cervi-cal response,sternocleidomastoid and rectus electromyography,contact heat evoked potentials,and motor unit number estimate;(3) we have attempted some experimental and clinical treatments forALS /MND,which include gene and stem cell therapies in animalmodels,and a pilot clinical trial of granulocyte colo-ny stimulating factor(G-CSF) forALS /MND patients(NCT00397423).
