The authors advocate a program for diagnosing Liver-Qi Deficiency Syndrome(LQDS) based on the TCM theory and clinical practice.Through investigation, LQDS was found to be widely existed as latent period or as external manifestation, which occupied 18.85% in Qi Deficiency Syndrome.The subjects were divided into four groups including normal group, Spleen-Qi Deficiency Syndrome(SQDS) group, LQDS with Liver diseases(LD) and LQDS with non-Liver diseases(NLD) group.In order to explore the essence,the simultaneous determinations were done on lactate dehydrogenase (LDH) and its isoenzyme,dopamineβ-hydroxylase(DβH),trace element Zn and Cu, and other serological indexes such as GPT, TP, Alb,A/G, etc.The results were, the content of LDH and trace element Zn in both LQDS-NLD and SQDS were significantly lower than that of normal group.DβH reflecting sympathetic nerve function in LQDS-NLD was significantly higher than that of both normal and SQDS group, comparing LQDS-LD and LQDS-NLD group, the content of GPT, LDH,LDHS and trace element Cu in former was significantly higher than that of the latter, but the content of TP,Alb,A/G, DβH and Zn in former was remarkably lower than that of the latter.In order to avoid confusion, in studying this syndrome,one should distinguish LD and NLD. |
