基于营卫理论探讨癌性脑病的发病机制

Analysis of Pathogenesis of Cancerous Encephalopathy Based on Nutrient-defense Theory

通过梳理营卫与癌病的相关性,指出各种致癌因素交互作用,损伤营卫,是癌病发生的核心病机。营卫源自中焦,根在肝肾,若肝肾亏虚,则营卫不充,固护不利,癌易犯脑,发为原发性脑癌。营不化血养脉,卫不护脉卫外,则癌侵入血脉,且循脉上行头面,转移性脑癌由此而生。营卫失调,致脏腑气化失司,则痰湿、瘀热、热毒等病理产物蜂起,各致病因素入脑窍,损脑脉,可引发头痛、眩晕、抑郁、乏力、消瘦等临床表现。以营卫辨识癌性脑病的发病机制,能更好地把握该病的复杂性与多样性,有利于临床治疗。

Through sorting out the correlation between nutrient-defense and cancer,it is pointed out that the interaction of various carcinogenic factors damaging nutrient-defense is the core pathogenesis of cancer.Nutrient-defense originates from the middle energizer,and the root is in liver and kidney. If liver and kidney are deficient,nutrient-defense is insufficient,failing to defend and protect,and cancer is easy to invade brain causing primary cerebral cancer. If nutrient fails to transform into blood and nourish vessels,and defense fails to protect vessels and defend outside,cancer will invade blood and vessels,following vessels up to head and face,resulting in metastatic cerebral cancer. Nutrient-defense disorder leads to dysfunction of qi transformation of zang-fu organs. The pathological products,such as phlegm and dampness,stagnant heat,heat toxin and the pathogenic factors invade brain,damage brain vessels,causing headache,vertigo,depression,fatigue,emaciation and other clinical manifestations. To identify the pathogenesis of cancerous encephalopathy by means of nutrient-defense can better grasp the complexity and diversity of the disease,which is conducive to clinical treatment.
