The cooccurrence of NPM1, FLT3-ITD, and DNMT3A mutations (i.e., triple mutation) is related to dismal prognosis in patients with acute myeloid leukemia (AML) receiving chemotherapy alone. In this multicenter retrospective cohort study, we aimed to identify whether allogeneic hematopoietic stem cell transplantation (allo-HSCT) could overcome the poor prognosis of DNMT3A^mutNPM1^mutFLT3-ITD^mut AML across four transplant centers in China. Fifty-three patients with triple-mutated AML receiving allo-HSCT in complete remission were enrolled. The 1.5-year probabilities of relapse, leukemia-free survival, and overall survival after allo-HSCT were 11.9%, 80.3%, and 81.8%, respectively. Multivariate analysis revealed that more than one course of induction chemotherapy and allo-HSCT beyond CR1 were associated with poor survival. To our knowledge, this work is the largest study to explore the up-to-date undefined role of allo-HSCT in patients with triple-mutated AML. Our real-world data suggest that allo-HSCT could overcome the poor prognosis of DNMT3A^mutNPM1^mutFLT3-ITD^mut in AML.

AIM:To evaluate the effect of intrave-nous oxycodone administration at different timing on rebound pain following the resolution of inter-costal nerve blockade after thoracoscopic surgery.METHODS:A total of 114 patients undergoing elec-tive thoracoscopic surgery under general anesthe-sia between January and July 2024 were selected.The patients were aged 18 to 64 years,regardless of gender,with a BMI of 18 to 30 kg/m2,and classi-fied as ASA Ⅰ-Ⅱ.The patients were randomly divided into three groups using a random number table:control group(Group C),oxycodone administration at the end of surgery group(Group Q1),and oxyco-done administration 6 hours postoperatively group(Group Q2),with 38 patients in each group.Group C received a normal saline injection at the end of surgery,Group Q1 received an intravenous injec-tion of oxycodone 0.04 mg/kg at the end of sur-gery,and Group Q2 received an intravenous injec-tion of oxycodone 0.04 mg/kg at 6 hours postoper-atively.Patients in the three groups were treated with a postoperative intravenous self-control anal-gesic pump(PCIA).The occurrence of rebound pain was recorded,the time of the first analgesic pump press,the number of presses,the dosage of sufent-anil,and the need for rescue analgesia were also recorded.Numerical Rating Scale(NRS)scores at rest and during movement were recorded at 6,8,12,24,48 and 72 hours postoperatively.The Pitts-burgh Sleep Quality Index(PSQI)was used to as-sess the sleep quality of patients the night before surgery and for two nights postoperatively.Adverse reactions such as respiratory depression,postoper-ative nausea and vomiting(PONV),and pruritus were recorded.RESULTS:Compared with group C and Q1,the incidence of rebound pain,postopera-tive sufentanil consumption,effective compression frequency of PCIA from 0-24 hours after surgery,and the rate of rescue analgesia were lower in Groups Q2(P＜0.05);Compared to Group C,the NRS scores at rest and during movement at 8,12,and 24 hours postoperatively were significantly lower in Groups Q1 and Q2(P＜0.05).However,compared to Group Q1,Group Q2 exhibited lower NRS scores at rest and during movement at 8,12,and 24 hours postoperatively(P＜0.05).On the first postoperative night,the PSQI scores of patients in Group Q2 were significantly better than those in Groups C and Q1(P＜0.05).There was no statistical-ly significant difference in the incidence of PONV among the three groups(P＞0.05).No respiratory depression,drowsiness,or pruritus were observed postoperatively in any of the groups.CONCLUSION:Intravenous injection of 0.04 mg/kg oxycodone 6 hours after surgery can reduce the occurrence of rebound pain after intercostal nerve block resolu-tion in thoracoscopic surgery and improves pa-tients' sleep quality.

Creating new germplasms and breeding new cultivars in peanut by radiation mutagenesis and tissue culture were conducted in this study, aiming to develop new breeding method of peanut. Mature seeds from Luhua 11, the most commonly grown peanut cultivar in Northern China, were treated by fast neutron irradiation. Then the embryo leaflets were separated from the irradiated seeds and inoculated on the media, and the regenerated seedlings were obtained through somatic embryogenesis pathway. The regenerated seedlings were grafted, acclimated and then transplanted into field and the selfed pods were harvested from 83 regenerated plants. The progenies were selected by the pedigree method, and 107 mutants were obtained from the progenies of the 83 regenerated plants. Different mutants showed obvious variation in many agronomic traits, including main stem height, branch number, pod shape and size, seed coat color, inner seed coat color, oil content and protein content etc. Yuhua 7, a new peanut variety with low oil content, early maturity and waterlogging tolerance was obtained. The yield of Yuhua 7 was over 14% higher than that of the mutagenic parent Luhua 11, and the oil content of kernels was 47.0%, lower than that of parent Luhua 11 with 52.1% oil content. Yuhua 7 had passed peanut variety regional multi-location trials in Liaoning Province in 2016 and its average yield was 13.8% higher than that of the control variety Baisha 1017. It had also passed national peanut variety registration, and the registration ID is "GPD peanut (2018) 370105". The results show that irradiation mutagenesis combined with tissue culture is an effective method for creating new germplasm and breeding new varieties of peanut.
