目的探讨瘀毒清对诱导慢性粒细胞白血病K562细胞株凋亡的作用.方法采用血清药理学方法,取慢性粒细胞白血病K562细胞株悬液分组,分别加入不含药血清(空白对照组)、含伊马替尼血清、含高剂量瘀毒清血清、中剂量瘀毒清血清、低剂量瘀毒清血清、含伊马替尼加高、中、低剂量瘀毒清血清,不加血清作为正常对照组.分别于干预后第12h、24 h、48 h和72 h通过Annexin V/PI双染法、流式细胞仪检测不同时间、不同药物组的细胞凋亡率.结果正常对照组的原代细胞有较低凋亡率,而空白对照组K562细胞的凋亡率更低,二者比较差异有统计学意义(P＜0.05).12h、24 h内瘀毒清含药血清低、中、高组凋亡率与正常对照组、空白对照组比较存在统计学差异(P＜0.05).药物组间相互比较亦有显著差异,并呈一定的时间剂量依赖性.瘀毒清高剂量组72 h未见凋亡率(31.48±6.58)进一步升高,与48 h比较无统计学差异,与瘀毒清中剂量组72 h的诱导凋亡率(27.54±5.89)比较也无统计学差异(P＞0.05).伊马替尼组12h开始即显示较高的凋亡率(23.80±6.94),与空白对照组细胞的凋亡率相比有统计学差异(P＜0.05).伊马替尼加瘀毒清各剂量组72 h的凋亡率与伊马替尼组、瘀毒清低、中、高组的凋亡率比较均有明显差异(P＜0.05).结论含瘀毒清血清对体外K562细胞有诱导凋亡作用,其作用呈一定时间、剂量依赖关系:瘀毒清与伊马替尼联合使用有增效作用.

Objective To explore the effect of Yuduqing on the apoptosis of CML K562 cells cultured in vitro and its molecular mechanism.Methods In serologic pharmacological test,the K562 cells were divided into 8 different groups.Serum with imatinib plus Yuduqing (high-dose,middle-dose,low-dose) were added into the cells respectively in the 8 groups of K562 cells.Morphological assessment of apoptosis was performed with optical microscope,the rates of apoptosis and the cell cycles analysis was performed with flow cytometry at 12 h,24 h,48 h and 72 h time points respectively after the intervention.Results The primary cell of normal control group had a low rate of apoptosis,while the blank control group K562 cell apoptosis rate was lower,the difference is significant (P＜0.05).The differences between the rates of apoptosis in high-dose,middle-dose and low-dose Yuduqing groups and those in normal control group and blank control group were significant in 12 hours or 24 hours (P＜0.05).Drug groups showed significant differences of pair-comparison in groups and a certain time dose dependence.But the rate of apoptosis(31.48± 6.58) in k562 cells in high-dose Yuduqing group did not increase further at 72 hours after the intervention and it was not statistically different from that of 48 hours,nor statistically different from that of middle-dose group at 72 hours(27.54±5.89) after the intervention (P＞0.05).The rate ofapoptosis in k562 cells in imatinib group (23.80±6.94) was relatively high at 12 hours after the intervention and it was significantly different from that in blank control group (P＜0.05).The rates of apoptosis in imatinib and Yuduqing (high-dose,middle-dose,and low-dose) groups were significantly higher than those in imatinib group or Yuduqing high-dose,middle-dose,and low-dose)groups (P＜0.05).Conclusion Serum with Yuduqing could induce apoptosis of K562 cells cultured in vitro and its action was dose-time dependent; Serum with Yuduqing (high-dose and middle-dose) was similar to serum with imatinib in inducing apoptosis of K562 cells cultured in vitro; Yuduqing could enhance the efficacy of imatinib.
