OBJECTIVE： To analyze the characteristics of liver pacifying medicinal in the treatment of brain disease to provide scientific evidence in clinical usage on ***： MEDLINE/PubMed, Google Scholar, and China National Knowledge Infrastructure Database were used as the literature sources. The Scientific name, Latin pharmaceutical name, Chinese name of 7 kinds of liver pacifying medicinal including Gouteng （Ramulus Uncariae Rhynchophyllae cure Uncis）, Tianma （Rhizoma Gastrodiae）, Juemingzi （Semen Cassiae Obtusifoliae）, Quanxie （Scorpio）, Wugong （Scolopendra）, Jiangcan （Bombyx Batryticatus）, and Dilong （Pheretima Aspergillum） were used as the keywords to search the databases for relevant publications up to July 2016. Their major compounds were also used as the keywords. The papers were selected based on the pharmacological activities and mechanisms of action related to brain diseases and subsequently, were analyzed and reviewed. We first described the origin, efficacy, and clinical indications of selected medicines, then brain disease specific activities focusing on stroke after the description of the general pharmacological activities. RESULTS： On the basis of the literature of scientific studies and clinical use in traditional medicine, we found and discussed the characteristics of liver pacifying medicinal in stroke treatment. First, liver-pacifying medicinal, or their components, might pass through the blood-brain barrier and act directly on neurons or on the neural network to provide protective effects against brain disease. Second, although it could be used throughout the disease duration, treatment of stroke might be more effective from the subacute up to the convalescent phase than the acute ***： We can suggest that live pacifying medicinal has beneficial pharmacological activities directly or indirectly on neurons in brain disease and is useful for the treatment of stroke from subacute to convalescent phase.

Spinal cord injury necessitates effective rehabilitation strategies, with exercise therapies showing promise in promoting recovery. This study investigated the impact of rehabilitation exercise on functional recovery and morphological changes following thoracic contusive spinal cord injury. After a 7-day recovery period after spinal cord injury, mice were assigned to either a trained group(10 weeks of voluntary running wheel or forced treadmill exercise) or an untrained group. Bi-weekly assessments revealed that the exercise-trained group, particularly the voluntary wheel exercise subgroup, displayed significantly improved locomotor recovery, more plasticity of dopaminergic and serotonin modulation compared with the untrained group. Additionally, exercise interventions led to gait pattern restoration and enhanced transcranial magnetic motor-evoked potentials. Despite consistent injury areas across groups, exercise training promoted terminal innervation of descending axons. In summary, voluntary wheel exercise shows promise for enhancing outcomes after thoracic contusive spinal cord injury, emphasizing the role of exercise modality in promoting recovery and morphological changes in spinal cord injuries. Our findings will influence future strategies for rehabilitation exercises, restoring functional movement after spinal cord injury.
