Density (mean±SD)	0.07±0.08	0.32±0.17†	0.08±0.06§

^*Expression of β1-integrin was detected more in experimental group rather than in control group (P<0.001).
^†Density of β1-integrin was higher in experimental group as compared with the controls (P<0.001).
^‡Expression of β1-integrin was more significantly decreased after operation (P<0.001).
^§Density of β1-integrin was significantly decreased after operation (P<0.001).
