Immunohistochemical analysis of PCNA expression intumors from different groups. The expression rate from siRNA/collagen group and siRNA/PEI/collagen group was significantly lower than that from control group and siRNA/Medium group. And the inhibitory effect on cell proliferation from the siRNA/PEI/collagen group was the most evident. **P < 0.01 compared with control group; ## P < 0.01 compared siRNA/collagen group
