According to the results of ELISA for relevant indicators of blood specimen in serums, the levels of TLR2, IL1-β, IL-6, and TNF-ɑ were significantly higher in primary hypertension group and primary hypertension combined with hyperlipidemia group than those in the control group (all P < 0.001, Table 3), with no significant difference in CCL2 levels among three groups (P=0.805, Table 3). This evidence concerns the gene CCL2 and hyperlipidemia.
