“hold不住”—从小儿遗尿看虚证的病理特点

“Cannot hold”-From the Pathological Features of Infantile Enuresis See Deficiency

"hold",英语中有"抑制"、"约束"、"控制"的意思。生物体的功能(及其相应结构)有进化、发育意义上的不同层次。不同层次功能间的关系上,以大脑皮层和交感神经为代表的高层次功能对低层次功能有抑制、控制作用。正常情况下,高层次功能能"hold住"低层次功能。虚证(指气虚证和阳虚证)情况下,高层次功能的强度减弱。因此,"hold不住"低层次功能,低层次功能的强度反弹性增强。虚证情况下,高层次功能"hold不住"低层次功能,小儿遗尿是明显的例子。小儿遗尿,指小儿到了能够控制排尿的年龄,而经常在夜间睡眠中不自觉地排尿。中枢神经系统对排尿控制的发育,是由低级中枢反射渐至大脑皮层意识控制的过程。遗尿患儿由于发育迟缓,大脑皮层兴奋性不足,因而低级中枢及其相应的排尿机制过度活跃,使夜间发生无意识的排尿。同时,小儿遗尿虚寒证表现突出。所以,从小儿遗尿看,高层次功能"hold不住"低层次功能,是虚证的病理特点。

＂hold＂, English is ＂suppression＂, ＂bound＂, ＂control＂. The function of living organisms （ and the cor responding structure） have different levels of evolution, developmental sense. The relationship between different levels of function, high level functions to the cerebral cortex and sympathetic nerve on behalf of inhibition, control of lower level functions. Under normal circumstances, the high level function ＂can hold＂ low level function. Deficiency syndrome （ de ficiency of Qi and yang deficiency refers to the case）, weaken the high level of intensity function. Therefore, ＂cannot hold＂ low level function, anti elastic strength low level enhancement. Deficiency condition, high level function ＂cannot hold＂ low level function, infantile enuresis is the obvious example. Infantile enuresis, refers to the children to control uri nation age, and often sleep at night, involuntary urination. Central nervous system on urination control development, is from the lower central reflex gradually to the cerebral cortex of conscious control of the process. Enuresis in children due to lack of growth retardation, cerebral cortex excitability, thus lower central and voiding mechanism corresponding overly ac tive, the nighttime unconscious urination. At the same time, to highlight the performance of infantile enuresis of Asthenia Cold syndrome. So, from the infantile enuresis, high level function ＂cannot hold＂ low level features, pathological charac teristics of deficiency syndrome.
