Dynamic expressions of monocyte chemo attractant protein-1 and CC chamomile receptor 2 after balloon injury and their effects in intimal proliferation

Table 2 Changes of ratio of intimal thickness and media thickness (ξ ± ΣΔ)

	Sham group	4th day group	7th day group	14th day group	28th day group
Sample No.	8	8	8	8	8
Intimal thickness/media thickness	0.03 ± 0.01	0.19 ± 0.04*	0.35 ± 0.05*	0.66 ± 0.07*	0.91 ± 0.15*

On 4, 7, 14 and 28 days after balloon injury, ratios of intimal thickness and media thickness were higher compared with the sham group and the differences were significant (*P < 0.05).
