Objective To explore the application of drones in blood emergency support during the 19th Asian Games Hangzhou in Shaoxing venue,so as to provide reference for future major events.Methods A retrospective analysis of drone delivery of emergency blood to two designated rescue hospitals in Shaoxing for the Asian Games was conducted.Ten emer-gency and 30 routine land blood delivery records from two designated hospitals in 2023 were randomly selected to compare with the blood delivery using drones.The blood temperature during the drone flight were monitored,the cold chain control during drone flight was evaluated,and the application of drone flight was reviewed.Results During the Hangzhou Asian Games,a total of 14 drones were used for blood delivery.The delivery time(min)by drone from the blood station to one of the designated hospitals was 11.83±0.09,and 20.80±3.29 by emergency land delivery and 23.23±3.54 by routine land de-livery(P＜0.05),meanwhile was 17.50±0.08,24.50±3.27 and 26.57±3.23 respectively to the other hospital(P＜0.05).Compared with land emergency blood delivery and routine blood delivery,blood delivery time by drone was much shorter,demonstrating better timeliness and stability.The temperature monitoring during the drone delivering showed that the suspen-ded red blood cells and platelets were in a range of 3.8-6.8℃ and 21.8-22.8℃,with a temperature difference of 0.5-0.9℃ and 0.2-1.0℃ between takeoff and landing respectively,demonstrating that the blood cold chain was under control,and the delivery ran safely and smoothly.Conclusion During major events,the use of drones for emergency blood delivery ensures the quality of the blood,with good timeliness,feasibility and operability,and is worthy of promotion and applica-tion.

OBJECTIVE: To investigate the expression of Wilms'tumor 1 () gene in patients with acute myeloid leukemia (AML), and to explore its application in predicting prognosis of AML in patients with wild or mutated nucleophosmin 1() and Fms-like tyrosine kinase 3-internal tandem duplication (). METHODS: One hundred and sixty-seven newly diagnosed AML patients(exclued M3 type) were enrolled in this study. The survival of patients were analyzed with Kaplan-Meier method. The clinical data, laboratory findings and the survival of patients were analyzed and compared between patients with high expression (high- group) and those with low expression (low- group), as well as among the patients with or wild type and mutants. RESULTS: The overall response rates (ORR) in high- and low- groups were 65.9% (83/126) and 95.1% (39/41), respectively (<0.01). Compared with the low- group, the high- group had lower 2-y overall survival (OS) rate (46.1% vs. 75.2%, <0.05) and 2-y disease free survival (DFS) rate (43.5% vs. 68.5%, <0.05). After induction chemotherapy, the patients with decreased gene expression ≥ 1log was associated with higher ORR and 2-y OS rate (all <0.05), but the advantage of 2-y DFS rate was not shown (>0.05). In patients with wild type, the high- group had inferior ORR and 2-y OS rate (all <0.05), while in the patients with wild type, the high- group had inferior ORR, 2-y OS rate and 2-y DFS rate (all <0.05). In patients with or FLT3 -ITD mutations, the expression had no significantly predicting values in treatment efficacy and survival (all >0.05). CONCLUSIONS gene overexpression indicated poor prognosis of AML patients; the patients with decreased gene expression ≥ 1 log after the first induction therapy show better prognosis than those with<1 log. The gene expression level at diagnosis can be used as an unfavorable prognostic factor for AML patients with or wild types.
