摘要: 目的:探讨存活蛋白重组腺病毒载体感染的树突细胞对体外淋巴瘤细胞生长的影响。方法:采取随机单盲的方法,选取体质量相近的健康小鼠120只,运用马兜铃酸诱导小鼠患淋巴细胞瘤,抽取其淋巴瘤细胞进行体外细胞培养,每只小鼠的一份淋巴瘤细胞培养液给予常规抗肿瘤药物为对照组,另一份加入存活蛋白重组腺病毒载体感染的树突状细胞培养液为观察组,对比分析2组淋巴瘤细胞培养液中癌细胞死亡情况和抗瘤情况。结果:观察组60%~79%、80%~100%瘤细胞培养液中瘤细胞死亡率分别为40.83%和29.17%,对照组死亡率分别为14.17%和3.33%,2组差异有统计学意义(P0.01)。观察组细胞培养液抗瘤情况明显优于对照组,其总有效率95.83%显著高于对照组的51.67%(P0.01)。结论:存活蛋白重组腺病毒载体感染的树突状细胞在一定程度上能有效抑制淋巴瘤细胞的生长与繁殖,对抗淋巴细胞瘤和在淋巴细胞瘤的治疗中有一定的积极意义。Abstract: Objective: To explore the expression and clinical significance of survival protein recombinant retroviral vector construction in diseases. Methods: One hundred and twenty healthy mice with close body weight were chosen by using random single-blind research method. The mice were given aristolochic acid to induce lymphocytoma,which was extracted for cell culture in vitro. In the control group,each mouse's lymphoma cell nutrient solution was added conventional normal antineoplastic drugs,while in the observation group it was added the dendritic cell nutrient protein recombinant retroviral vector. The cancer cell death and anticancer conditions in the lymphoma cell nutrient solution were compared and analyzed between the two groups. Results: In the observation group,The death rates for the cancer cell culture fluid with 60%- 79% and 80%- 100% oncocyte were 40. 83% and 29. 17% respectively,while they were 14. 17% and 3. 33% in the control group. The difference was significant( P 0. 01). The cell culture fluid of the observation group was significantly better than that of the control group in eliminating oncocyte with a total efficiency of 95. 83%,which was significantly higher than that of the control group( 51. 67%)( P 0. 01). Conclusions: The dendritic cells infected by the survival protein recombinant retroviral vector can effectively restrain the lymphoma cells growth and reproduction in some degree,and antagonize the lymphoma cell. They have certain positive meaning in the treatment of lymphocytoma.
