Results:Kanglaite combined Gemcitabine remarkably decreased the protein expression of bcl-2,raised the expression of Bax,increased the apoptosis rate of the pancreatic cancer and contract the gross tumor volume. Kanglaite greatly decreased the protein expression of VEGF of the tumor cell. Conclusion:Therapeutic efficacy of Kanglaite combined Gemcitabine is far better than separate use of the two medicines in the pancreatic cancer transplantation tumor treatment.展开更多
