[Study on relationship between brain function and syndrome differentiation-typing of TCM in non-insulin dependent diabetes mellitus].

The relationship between brain function and syndrome-types of TCM in 51 patients with non-insulin dependent diabetes mellitus (NIDDM) was observed. The syndromes were divided into three types. (1) Yin Deficiency with internal excessive Heat (YDIEH), 15 cases; (2) Qi-Yin Deficiency (QYD), 21 cases; (3) Deficiency of both Yin and Yang (DYY), 15 cases. The control group consisted of 30 healthy subjects matched in age, sex and educational level. The brain function were tested by neurobehavioral and neuroelectrophysiological tests. The former included short-term memory, thinking, eye-hand coordination and emotion tests; the latter consisted of brainstem auditory evoked potentials (BAEP), visual evoked potentials (VEP) and somatosensory evoked potentials (SEP). The results showed that the brain function in YDIEH group approached normal controls, and the brain function in QYD and QYY groups were significantly deteriorated. The results suggested that the brain function were correlated with the syndrome-types of patients with NIDDM. This would be valuable for diagnosis and treatment of NIDDM in TCM.
