Dr. Jixiang Ren and team from the Affiliated Hospital to Changchun University of Chinese Medicine proposed a therapeutic principle for Poxue Huayu and Tianjing Busui (i.e., breaking blood stasis, replenishing essence). The researchers established cerebral hemorrhage rat models which were intragastrically administered 5, 10, 20 g/kg Poxue Huayu and Tianjing Busui Decoction, supplemented with Hirudo, raw rhubarb, raw Pollen Typhae, gadfly, Fructrs Trichosanthis, Radix Notoginseng, Rhizoma Acori Talarinowii, and glue of tortoise plastron, once a day, for 14 consecutive days. Their findings, which were published in the Neural Regeneration Research (Vol. 8, No. 22, 2013), demonstrated that brain water content significantly reduced in rats with cerebral hemorrhage, and intracerebral hematoma volume markedly reduced after treatment. Brain-derived neurotrophic factor, tyrosine kinase B and vascular endothelial growth factor expression noticeably increased around the surrounding hematoma. Moreover, neurologic impairment obviously reduced. Poxue Huayu and Tianjing Busui Decoction can markedly elevate the expression of brain-derived neurotrophic factor, tyrosine kinase B and vascular endothelial growth factor in the brain, thereby providing a new scientific therapeutic method for protecting neurons after cerebral hemorrhage.
