COVID-19 has been an emerging and rapidly evolving risk to people of the world in 2020.Facing this dangerous situation,many colleagues in Neurorestoratology did their best to avoid infection if themselves and their patients,and continued their work in the research areas described in the 2020 Yearbook of Neurorestoratology.Neurorestorative achievements and progress during 2020 includes recent findings on the pathogenesis of neurological diseases,neurorestorative mechanisms and clinical therapeutic achievements.Therapeutic progress during this year included advances in cell therapies,neurostimulation/neuromodulation,brain-computer interface(BCI),and pharmaceutical neurorestorative therapies,which improved neurological functions and quality of life for patients.Four clinical guidelines or standards of Neurorestoratology were published in 2020.Milestone examples include:1)a multicenter randomized,double-blind,placebo-controlled study of olfactory ensheathing cell treatment of chronic stroke showed functional improvements;2)patients after transhumeral amputation experienced increased sensory acuity and had improved effectiveness in work and other activities of daily life using a prosthesis;3)a patient with amyotrophic lateral sclerosis used a steady-state visual evoked potential(SSVEP)-based BCI to achieve accurate and speedy computer input;4)a patient with complete chronic spinal cord injury recovered both motor function and touch sensation with a BCI and restored ability to detect objects by touch and several sensorimotor functions.We hope these achievements motivate and encourage other scientists and physicians to increase neurorestorative research and its therapeutic applications. 展开更多

Breakthroughs with rapid changes are the themes of the development in Neurorestoratology this year.Given the very difficult circumstances of the persistent COVID-19 pandemic,most of the colleagues in Neurorestoratology have conducted meaningful research and obtained encouraging results,as described in the 2020 Yearbook of Neurorestoratology.Neurorestorative progress during 2021 depicts recent findings on the pathogenesis of neurological diseases,neurorestorative mechanisms and clinical therapeutic achievements.The pathogenesis and risk factors of Alzheimer's disease were parts of the most prominent hot research topics.Yet,it remains controversial whether b-amyloid accumulation and tau protein deposition are the results of,or the reasons for the neurodegenerative processes.Neurogenesis is an important neurorestorative mechanism,however,it is questionable whether neural stem cells are present in the adult humans brain.Thus,neurogenesis may not derive from endogenous neural stem cells in the adult humans.Neurorestorative treatments were important areas of the 2021 research efforts and these therapies are improving the quality of life in patients with neurological diseases.There was major exploration of cell-based therapies for neurological disease and injury.However,unfortunately several multi-center,double-blind or observing-blind,placebo controlled,randomized clinical trials of mesenchymal stromal cells or products of mesenchymal stem cells failed to show positive results in ischemic stroke when employed in the sub-acute or recovery phases as there were no appreciable differences in the quality of life as compared with controls.Excitingly,increased numbers of clinical investigations of brainecomputer interface(BCI)were reported that showed benefits for patients with neurological deficits.In pharmaceutical neurorestorative therapies,Aducanumab(Aduhelm)and Sodium Oligomannate are approved respectively by the United States Food and Drug Administration(USFDA)and the China National Medical Products Administration(NMPA)to treat patients with mild-to-moderate Alzheimer's disease.Although,the decisions to approve these drugs are highly contentious in the medical and scientific community because of the contradictory findings or other problems associated with the drug usage.We believe that repeating low-level evidence studies that showed negative results or scanty evidences in randomized control trials is of little significance.However,we strongly recommend conducting multi-center,double-blind,placebo controlled,randomized clinical trials for promising innovative therapeutic methods to facilitate their possible clinical translation. 展开更多

There was much progress in the field of Neurorestoratology in the year of 2022.It included highlighting advances in understanding the pathogenesis of neurological diseases,neurorestorative mechanisms,and clinical treatments as compiled in the 2022 yearbook of Neurorestoratology.There is still controversy about whether amyloid b-protein and tau protein deposition are the reasons for or the results of Alzheimer's disease(AD)pathology.The fabricated images in important key articles that speculated on the reasons for AD pathogenesis were found.Cholinergic deficiency and decrease or loss in strength of glutamatergic synapse,limited or failing bidirectional cholinergic upregulation in early cognitive impairment,or progressive posterior-to-anterior cortical cholinergic denervation could result in the appearance of AD.Exploration of neurorestorative mechanisms were found in more detail ways in neuromodulation,immunomodulation,neurogenesis,neural network or circuitry reconstruction,neuroprotection,nervous structural repair,and neuroplasticity.Several kinds of cell therapies for neurological diseases showed neurorestorative effects in open-label and/or non-randomized clinical studies or trials.However,mesenchymal stromal cells and mononuclear cells did not demonstrate neurorestorative effects or improve the quality of life for patients with neurodegenerative diseases or neurotrauma including stroke,spinal cord injury(SCI),and amyotrophic lateral sclerosis in randomized,double-blind,placebo-controlled clinical trials(RDPCTs).Clinical treatments through neurostimulation/neuromodulation and the brainecomputer/machine interface yielded positive results in AD,Parkinson's disease,stroke,SCI,cerebral palsy,and other diseases in RDPCTs.Neurorestorative surgery,pharmaceutical neurorestorative therapy and other interventions have demonstrated neurorestorative effects for various considered incurable neurological diseases in RDPCTs.Thus,this year,additional guidelines,assessment scales,and standards were set up or revised.These included guidelines of clinical neurorestorative treatments for brain trauma(2022 China version),clinical cell therapy guidelines for neurorestoration(IANR/CANR 2022),SCI or dysfunction quality of life rating scale(SCIDQLRS)(IANR 2022 version).Neurorestorative effects of varying therapeutic strategies with higher standards of evidence-based medicine are now benefiting patients with currently incurable neurological diseases.Hopefully some of them may become routine therapeutic interventions for patients with these diseases in the near future. 展开更多
