In this research, Syndrome of Deficiency of Spleen (DS) and Stagnation of Liver-Qi (SLQ) as well as observations of electrogastrogram (EGG), gastric mucosal pathology and pulse cardiovascular examination were investigated in 56 cases of chronic gastric diseases (CGD). The results showed: (1) In SLQ with DS the amplitude of EGG was significantly higher than that of the control group (P < 0.01), it often indicated the active period of pathologic change, but in DS with SLQ, the amplitude of EGG was significantly lower than that of the control group (P < 0.01), it frequently denoted the static period. In case that DS equalled to SLQ, the amplitude of EGG was significantly higher than that of the control group (P < 0.01). It revealed that there were no significant difference between the patient's number of static and active periods (P > 0.05). It is valuable in Syndrome Differentiation of Deficiency and Excess and analysis of Superficiality and Origin in CGD. (2) Cardiovascular function was also affected in Syndrome differentiation of DS and SLQ. DS with SLQ manifested itself as reduction of left ventricle pump and declination for metabolism of microcirculation, they had significant difference as compared with the control group (P < 0.05), while SLQ with DS or equality between DS and SLQ had the normal function of left ventricle pump and metabolism of microcirculation, even though cardiac output were higher than that of control group (P < 0.05). It showed that the traditional Chinese medicine theory of interrelation among Heart and Spleen, Liver had their own hemodynamic bases.
