Objective To screen the laboratory medicine indexes for auxiliary diagnosis of kidney deficiency syndrome. Methods According to research results about modern biomedical pathomechanism of kidney deficiency syndrome

referring to literature reports on abnormal laboratory medicine indexes of patients with deficiency of the kidney

and combined with present situation of clinic routine inspection items

the related laboratory indexes were preliminarily screened. They were 7 immune indexes

including immunoglobulin A（ Ig A）

immunoglobulin G（ Ig G）

immunoglobulin M（ Ig M）

complement C3

complement C4

helper T lymphocytes（ CD4 +） and inhibited cytotoxic T cell（ CD8 +）; 5 indexes related to hypothalamic-pituitary-adrenal axis

including adrenaline（ ADR）

norepinephrine（ NOR）

adrenocorticotropic hormone（ ACTH）

dopamine（ DOP）

and cortisol; 5 indexes of serous microelement including calcium（ Ca）

magnesium（ Mg）

copper（ Cu）

zinc（ Zn）

and iron（ Fe）. Twenty-five patients with kidney-Yang deficiency syndrome

25 patients with kidney-Yin deficiency syndrome

and 24 healthy volunteers were chosen to compare the indexes. Results Compared with those in the healthy control group

serous levels of complement C3

CD4 + / CD8 +

Ig M

ACTH

Mg

Cu

Zn

Fe all reduced significantly in the kidneyYang deficiency syndrome group and the kidney-Yin deficiency syndrome group（ P < 0. 01）; In the kidney-Yang deficiency syndrome group and the kidney-Yin deficiency syndrome group

the levels of dopamine were higher than that in the healthy control group

and there was significant difference in the level of dopamine between the kidney-Yin deficiency syndrome group and the healthy group（ P < 0. 05）; In the kidney-Yang deficiency syndrome group

levels of NOR and ADR were much lower than those in the kidney-Yin deficiency syndrome group and the healthy control group（ P < 0. 05）; In the kidney-Yin deficiency syndrome group

level of Ig G was much higher than that in the healthy control group（ P < 0. 01）. Conclusion Patients with kidney deficiency syndrome showed the changes of body immune

hormones related to adrenal and metabolic indexes of microelement. In clinic

combined with apparent signs of patients

doctors may make combinatorial detection with the above-mentioned indexes to realize quantitative detection and diagnosis by types of kidney deficiency syndrome.
