Table 3

The comparison of the expressing of target protein in brain tissue in three groups.

group	Number of Aβ positive cells		Number of p-Tau positive cells		Number of PSD95 positive cells
	hippoca	prefrontal	hippoca	prefrontal	hippocam	prefrontal
	mpus	cortex	mpus	cortex	pus	cortex
C	19 ± 13	38 ± 11	40 ± 11	48 ± 8	23 ± 5	37 ± 4
M	55 ± 13	59 ± 16	62 ± 20	76 ± 11	6 ± 3	16 ± 4
D	30 ± 9	46 ± 12	41 ± 10	65 ± 11	17 ± 7	26 ± 2

C: control group, M: POCD group, D: POCD + Dex group, compared with control group, compared with POCD group, was considered as statistical significance.
