[Graduated quantitative diagnosis of spleen deficiency syndrome]

90 Cases with Spleen Deficiency Syndrome (SDS) in various diseases of different body system were studied to obtain a quantitative measurement of the syndrome for more accurate diagnosis. Rates of symptom manifestation of SDS, absorptivity of D-xylose, activity of salivary amylase, hemoglobin level, RBC count, plasma albumin, cardiac function as well as some parameters of hemorheology and lymphocyte transformation rate were observed. The results clearly showed that the D-xylose absorptivity was much lower in patients with higher appearance rate of SDS symptoms, which was dose-dependent. Along with the lowering of D-xylose absorptivity, the values of above-mentioned parameters dropped were positively correlated to it. On the contrary, the peripheral vascular resistance elevated as D-xylose absorptivity dropped. The author divided the SDS into three stages as a graduated quantitative diagnosis based on the drop of D-xylose absorptivity, the increase of SDS symptom and other changes of laboratory findings.
