摘  要:目的研究测定人淋巴瘤细胞株Raji摄取18F-氟脱氧葡萄糖(18F—FDG)和18F-氟脱氧胸腺嘧啶核苷(18F—FLT)的方法并比较两者的差异。方法在不同条件下测定淋巴瘤细胞株Raji对18F—FDG和18F—FLT的细胞结合率:细胞数量1×10^5-1×10^7/瓶;18F-FDG和18F—FLT的放射性活度1.85—29.6kBq;反应时间20—120min;葡萄糖浓度0~11.1mmol/L。结果每瓶1×10^7个细胞、加入3.7kBq18F.FDG、葡萄糖浓度在0—2.78mmol/L、作用100min,18F-FDG细胞结合率达到(50.42×1.07)%;每瓶1×10^7个细胞、加入3.7kBq 18F—FLT、作用100min,18F—FLT细胞结合率达到(59.48±0.77)%;18F—FDG和18F-FLT的细胞结合率之间具有统计学差异(F=1192.805,P〈0.001)。结论Raji细胞与18F—FDG的结合率与细胞数量、作用时间及葡萄糖浓度有关,与18F-FDG的放射性活度无关;Raji细胞与18F-FLT的结合率与细胞数量和作用时间有关,与18F-FLT的放射性活度及葡萄糖浓度无关;同等条件下,Raji细胞对18F-FLT的细胞结合率高于18F—FDG。Objective To investigate the binding characteristics of 18F-fluorodeoxyglucose 18F-FDG) and 18F-fluorodeoxythymidine (18F-FLT) with human lymphoma cell Raji and the differences between them. Methods The binding rates of 18F-FDG and 18F-FLT was measured under different conditions: 1×10^5-1×10^7 cells, 1.85-29.6 kBq 18F-FDG or 18F-FLT, 0-11.1 mmol/L glucose levels and 20-120 min to measure. Results The binding rate of 18F-FDG was (50.42±1.07) % at the condition of 1×10^7 cells, 3.7 kBq 18F-FDG, 0-2.78 mmol/L glucose levels, 100 min, while 18F-FLT was (59.48±0.77) % at the same conditions. The difference of binding rates between 18F-FDG and 18F-FLT was significant (F=1192.805, P〈0.001). Conclusion The uptake of 18F-FDG and 18F-FLT in human lymphoma Raji cell is high, and at the same condition, the uptake rate of 18F-FLT is higher than 18F-FDG.
