摘      要：OBJECTIVE: To investigate the effect of optimal combination(E) of Huangqi(Radix Astragali Mongolici) and Ezhu(Rhizoma Curcumae Phaeocaulis) on proliferation and apoptosis of A549 lung cancer cells and the possible mechanism underpinning the ***: A uniform design method was used to optimize the E of Huangqi(Radix Astragali Mongolici) and Ezhu(Rhizoma Curcumae Phaeocaulis) in A549 lung cancer cells. MTS assay was applied to analyze the effect of the component formula ofHuangqi(Radix Astragali Mongolici) and Ezhu(Rhizoma Curcumae Phaeocaulis) on A549 cells viability in various uniform design groups. A549 cells with exponential growth in routine culture were exposed to Co Cl_2(200 μmol/L) to mimic hypoxic conditions. Group 0 was treated with RPMI-1640, the group Co Cl_2 was treated with Co Cl_2(200 μmol/L),the group DDP + Co Cl_2 was treated with 4 mg/L Cisplatin injection(DDP) + Co Cl_2(200 μmol/L), and the drug group was treated with various dose of E(0.5 E, 1 E, 2 E) + Co Cl_2(200 μmol/L). All groups were cultured for 24 h. Cell apoptosis was measured by Annexin V-FITC/propidium iodide double staining and flow cytometry. Western blot assay and quantitative real-time polymerase chain reaction(q RT-PCR) were employed to detect the protein and m RNA expression of B-celllymphoma-2(Bcl-2),Bcl-2-associated X protein(Bax) and cysteinyl aspartate specific proteinase-3(caspase-3).RESULTS: The E obtained by the uniform design was comprise of 200 mg/L Astragalus polysaccharide(X1) and 32 mg/L Curcumin(X3). Group DDP+Co Cl_2, group 1 E + Co Cl_2 and group 2 E + Co Cl_2 promoted the apoptosis of A549 cells(P 0.05). Compared with group 0, various doses of E + Co Cl_2 could up-regulate the expression of Bax and caspase-3 and down-regulate the expression of Bcl-2 at protein and m RNA levels(P 0.05).CONCLUSION: Astragalus polysacchari
