The invention discloses a traditional Chinese medicine composition for preventing and treating vascular dementia. The traditional Chinese medicine composition for preventing and treating vascular dementia comprises ginseng, gastrodia elata, Euonymus alatus and Ligusticum wallichii. The composition can be prepared into Chinese herbal preparation crude drug for preventing and treating vascular dementia. The ginseng and the Ligusticum wallichii are extracted with alcohol, the gastrodia elata and the Euonymus alatus are extracted with water, the obtained alcohol extract and the obtained water extract are mixed, the mixture is dried under vacuum and then is pulverized to obtain the final product, and the composition can be directly taken orally or is prepared into other dosage forms such as granules, capsules, soft capsules, electuaries, pills and decocted extracts. The composition is completely prepared from natural medicinal plants, does not contain hormones, and does not contain other chemical synthetic products such as pigment, and even if a patient orally takes the composition continuously, no toxic and side effect is performed on the human body. The traditional Chinese medicine composition contains various easily absorbable ingredients such as ginsenoside, chuanxiongol, chuanxiongzine, gastrodin and quercetin, can be effectively used for treating the vascular dementia, increases cerebral blood flow, reduces cerebral vascular resistance, improves body immunocompetence, and has effects of tonifying deficiency, promoting intelligence, suppressing the hyperactive liver, subsiding Yang, dispelling blood stasis and dredging collaterals.

The invention discloses TAT-LBD-PEP fusion protein and application of the TAT-LBD-PEP fusion protein in treatment of central nervous system lesion. The TAT-LBD-PEP fusion protein is combined with myelin inhibiting factors MAG, Nogo-66 and OMgp, accordingly the axon regenerative capacity is promoted through antagonism PirB effect, and the TAT-LBD-PEP fusion protein has the advantages of being high transduction efficiency and easily transmitting a blood-spinal barrier and a blood brain barrier, can transduce targeting to a hurt region and has the enrichment effect on an ischemic region. The problems that additional harm of nervous tissues is caused by the protein injection in a micro-injection mode or other injection modes and macromolecule cannot transmit the blood-spinal barrier and the blood brain barrier are solved, and the shortcoming that corresponding biological concentration cannot be met is overcome, and the targeting is transduced to the ischemic region through a ligand binding domain (LBD). The TAT-LBD-PEP fusion protein can be prepared in large-scale mode, is low in cost and high in activity, and is used for treatment of various brain and spinal cord injury including cerebral ischemia hypoxia, cerebral hemorrhage, cerebral trauma, spinal cord injury and the like and promoting regeneration of nervous tissues and neural functional recovery.
