The purpose of this study is to evaluate the dosages of recombinant human serum albumin/granulocyte colony-stimulating factor fusion protein by injection for preventing neutrophilic granulocytopenia among chemotherapy patients.

Conduct Pharmacokinetics (PK) study on recombinant human serum albumin/granulocyte colony-stimulating factor fusion protein with recombinant human granulocyte colony-stimulating factor injection as a control.

• Brief Protocol: Treat the patients taking Taxotere+Epirubicin+Cyclophosphamide (TEC) treatment or Taxotere+Epirubicin (TE) treatment chemotherapy with the study medicine or positive control during the period between two chemotherapy treatments.
• Positive control：recombinant human granulocyte colony-stimulating factor injection.
• Targeted patients: breast cancer
