摘　　要：目的:观察补中益气汤对人胃癌顺铂耐药细胞株SGC-7901CDDP奥沙利铂化疗敏感性的增强作用及机制。方法:将30株SGC-7901CDDP细胞株随机分为空白对照组、奥沙利铂组和补中益气组,每组10株,均置于DMEM高糖培养液中培养。空白对照组不添加其他药液培养,奥沙利铂组添加奥沙利铂注射液1 mL模拟化疗环境,补中益气组添加奥沙利铂注射液1 mL+补中益气汤3 mL进行培养。培养48 h后进行细胞化疗敏感性指标(细胞凋亡率、细胞迁移率、细胞周期、细胞生物学参数及化疗增敏比)及反应机制相关因子(survivin、Bcl-2、NF-κB)检测。结果:与空白对照组比较,奥沙利铂组和补中益气组的细胞凋亡率均较高(P<0.05),且补中益气组的细胞凋亡率明显高于奥沙利铂组(P<0.05)。在24 h和48 h两个时点,奥沙利铂组和补中益气组的划痕面积明显低于空白对照组(P<0.05),且补中益气组的划痕面积更小(P<0.05)。与空白对照组比较,奥沙利铂组和补中益气组细胞处于G2/M期的DNA占比明显下调,处于G1、S期的DNA占比明显上升(P<0.05);与奥沙利铂组比较,补中益气组细胞G2/M期DNA占比明显较低,处于G1、S期的DNA占比明显较高(P<0.05)。与空白对照组比较,奥沙利铂组和补中益气组的细胞化疗生物学参数(D_(0)、D_(q)、N)均显著下降,而化疗增敏值显著上升(P<0.05);与奥沙利铂组比较,补中益气组的细胞化疗生物学参数(D_(0)、D_(q)、N)均显著下降,而化疗增敏值显著上升(P<0.05)。与空白对照组比较,奥沙利铂组和补中益气组的survivin、Bcl-2、NF-κB表达均明显下调(P<0.05);与奥沙利铂组比较,补中益气组的survivin、Bcl-2、NF-κB表达均明显降低(P<0.05)。结论:补中益气汤能通过抑制细胞迁移、诱导细胞凋亡和提升人胃癌顺铂耐药细胞株的奥沙利铂化疗敏感性,其作用机制可能是补中益气汤通过下调survivin、Bcl-2、NF-κB细胞因子水平,从而提Objective:To observe the enhancement effect and mechanism of Buzhong Yiqi Decoction on the chemosensitivity of cisplatin-resistant human gastric cancer cell line SGC-7901 CDDP to oxaliplatin.Methods:Thirty SGC-7901 CDDP cell lines were randomly divided into blank control group,oxaliplatin group and Buzhong Yiqi Decoction group,with 10 cells in each group,all cultured in DMEM high glucose medium.The blank control group was cultured without adding other liquid medicines.In the oxaliplatin group,1 mL of oxaliplatin injection was added to simulate a chemotherapy environment.The Buzhong Yiqi Decoction group was supplemented with oxaliplatin injection 1 mL+Buzhong Yiqi Decoction 3 mL for culture.After 48 hours of culture,the chemosensitivity indicators(apoptosis rate,cell migration rate,cell cycle,cell biological parameters,and chemosensitization ratio) and response mechanism-related factors(survivin,Bcl-2,NF-κB) were detected.Results:Compared with the blank control group,the cell apoptosis rates in the oxaliplatin group and the Buzhong Yiqi Decoction group were both higher(P<0.05),and the cell apoptosis rate in the Buzhong Yiqi Decoction group was significantly higher than that in the oxaliplatin group(P<0.05).At 24 h and 48 h,the scratch areas of the oxaliplatin group and the Buzhong Yiqi Decoction group were significantly lower than those of the blank control group(P<0.05),and the Buzhong Yiqi Decoction group had a lower scratch area than the oxaliplatin group(P<0.05).Compared with the blank control group,the proportion of DNA in the G2/M phase of the oxaliplatin group and the Buzhong Yiqi Decoction group was significantly down-regulated,and the proportion of DNA in the G1 and S phases was significantly higher(P<0.05).Compared with the oxaliplatin group,the proportion of DNA in the G2/M phase of the Buzhong Yiqi Decoction group was significantly lower,and the proportion of DNA in the G1 and S phases was significantly higher(P<0.05).Compared with the blank culture group,the biological parameters of cell chemotherapy
