Mitochondrial factor and cell cytokines play important roles in the incidence of vascular dementia (VD), but their correlations with inflammatory and mitochondrial factors and the role of both in the kidney essence deficiency pattern and phlegm turbidity blocking orifice pattern are not clear. This study was aimed at studying the correlations between the serum mitochondrial factor and cell cytokines with TCM Syndrome Scale in vascular dementia. According to the inclusion criteria we collected 108 vascular dementia patients which were divided into the kidney essence deficiency pattern and phlegm turbidity blocking orifice pattern based on the TCM Syndrome Scale. We measured serum tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-18 (IL-18) concentration using an enzyme-linked immunosorbent assay (ELISA) and serum malondialdelyde (MDA) and superoxide dismutase (SOD) was quantified according to instructions of kits from the 108 patients (45 in kidney essence deficiency pattern, 63 in phlegm turbidity blocking orifice pattern). The scale scores were assessed using TCM Syndrome Scale, MMSE, Hachinski, Barthel, BBS, CDR. There was a significant difference on the scores of CDR and the factors of the memory, judgment, social affairs, personal care, family and hobbies among the two groups, The means of kidney essence deficiency group was higher than that of phlegm turbidity blocking orifice pattern group. IL-18 and SOD in the phlegm turbidity blocking orifice group was higher than those in the kidney essence deficiency pattern; IL-6 in phlegm turbidity blocking orifice pattern group was lower than that in the kidney essence deficiency pattern. By logistic regression analysis, we demonstrated that high concentration of IL-6, TNF-α, and MDA were associated with increased TCM syndrome scores in two groups, while IL-6, IL-18, TNF-α, SOD were associated with decreased MMSE, Barthel. Our study support the notion that IL-6 plays a more important role in the integral of kidney essence deficiency pattern, IL-18 is a more important factor in phlegm turbidity blocking orifice pattern. The results can be used as the theoretical basis of traditional Chinese Medicine prescription and pharmacological research in future, through decrease in IL-6 lever and increase in SOD in integral kidney essence deficiency pattern, and IL-18 as the main anti inflammation index in phlegm turbidity blocking orifice pattern.
