Objective To explore the efficacy of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) in distinguishing the properties of abnormal lymph nodes and its role in assessing the prognosis of patients with related diseases, and to provide more precise evidence for clinical diagnosis and treatment regimen formulation. Methods The clinical data of 97 patients with malignant tumors diagnosed with abnormal lymph nodes at Wuxi People’s Hospital Affiliated to Nanjing Medical University between April 2024 and June 2025 were retrospectively analyzed. Patients were divided into a malignant lymph node group (n=47) and a benign lymph node group (n=50) based on pathological results. PET/CT metabolic parameters [maximum standardized uptake value (SUVmax), mean standardized uptake value (SUVmean), metabolic tumor volume (MTV), and total lesion glycolysis (TLG)] were compared between the two groups of patients. Receiver operating characteristic curves were used to evaluate the diagnostic value of 18F-FDG PET/CT parameters for abnormal lymph nodes. Progression-free survival was compared among patients in the malignant lymph node group stratified by different levels of SUVmax, SUVmean, MTV, and TLG. Results SUVmax, SUVmean, MTV, and TLG were significantly higher in the malignant lymph node group than in the benign lymph node group (P < 0.05). The areas under the receiver operating characteristic curves for predicting malignant lymph nodes with SUVmax, SUVmean, MTV, and TLG were 0.761, 0.855, 0.860, and 0.792, with sensitivities of 74.47%, 82.98%, 74.47%, and 70.21%, and specificities of 76.00%, 76.00%, 90.00%, and 82.00%, respectively (P < 0.05). Comparison of progression-free survival in patients with malignant lymph nodes with different 18F-FDG PET/CT parameter levels revealed that patients with lower levels of SUVmax, SUVmean, MTV, and TLG had significantly longer progression-free survival than those with higher levels (Log-rank χ2=4.297, P=0.038; Log-rank χ2=6.569, P=0.010; Log-rank χ2=5.970, P=0.015; and Log-rank χ2=7.422, P=0.006, respectively). Conclusion 18F-FDG PET/CT metabolic parameters (SUVmax, SUVmean, MTV, and TLG) demonstrate high efficacy in the differential diagnosis of benign and malignant abnormal lymph nodes and prognostic evaluation, providing significant guidance for clinical treatment decisions.

OBJECTIVE To explore optimization pathways for the drug traceability code management model in outpatient pharmacy workflows, providing practical evidence for enhancing the efficiency of pharmaceutical service. METHODS Taking the outpatient pharmacy of the First Affiliated Hospital of Sun Yat-sen University as the research subject, a comprehensive drug traceability system was established through three key interventions: upgrading the information system architecture [including integration of the hospital information system (HIS) with the traceability platform], workflow optimization (reorganizing the inventory-dispensing-verification tripartite process), and designing a dual-mode traceability data collection mechanism (primary data capture at dispensing stations and supplementary capture at verification stations). Operational efficiency differences before and after implementation were analyzed using the medical insurance data and service timeliness metrics in September 2024. RESULTS After the implementation of drug traceability code management, in terms of data collection: Mode Ⅰ (verification-stage capture) uploaded 26 144 records, while Mode Ⅲ (inventory-as-sales capture) uploaded 443 061 records, totaling 469 205 entries; in terms of time efficiency: average drug dispensing time increased from 28.74 s to 43.37 s (enhanced by 51%). Through dynamic staffing adjustments, patient wait time only extended from 8.04 min to 8.67 min (enhanced by 8%). CONCLUSIONS Drug traceability code management can be effectively implemented via a “system reconstruction-process reengineering-human-machine collaboration” trinity strategy, leveraging informatization (e.g., dual-mode data capture) to offset manual operation delays, which validates the feasibility of balancing national traceability demands with service efficiency in outpatient pharmacies.

Objective:To construct a novel dual-specific antibody targeting human CD123 (CD123 DuAb) and study its effects in acute myeloid leukemia (AML) .Methods:Based on the variable region of the CD123 monoclonal antibody independently developed at our institution, the CD123 DuAb expression plasmid was constructed by molecular cloning and transfected into ExpiCHO-S cells to prepare the antibody protein. Through a series of in vitro experiments, its activation and proliferation effect on T cells, as well as the effect of promoting T-cell killing of AML cells, were verified.Results:① A novel CD123 DuAb plasmid targeting CD123 was successfully constructed and expressed in the Expi-CHO eukaryotic system. ②The CD123 DuAb could bind both CD3 on T cells and CD123 on CD123 + tumor cells. ③When T cells were co-cultured with MV4-11 cells with addition of the CD123 DuAb at a concentration of 1 nmol/L, the positive expression rates of CD69 and CD25 on T cells were 68.0% and 44.3%, respectively, which were significantly higher than those of the control group ( P<0.05). ④Co-culture with CD123 DuAb at 1 nmol/L promoted T-cell proliferation, and the absolute T-cell count increased from 5×10 5/ml to 3.2×10 6/ml on day 9, and CFSE fluorescence intensity decreased significantly. ⑤ With the increase in CD123 DuAb concentration in the culture system, T-cell exhaustion and apoptosis increased. When the CD123 DuAb was added at a concentration of 1 nmol/L to the culture system, the proportion of CD8 + PD-1 + LAG-3 + T cells was 10.90%, and the proportion of propidium iodide (PI) - Annexin Ⅴ + T cells and PI + Annexin Ⅴ + T cells was 18.27% and 11.43%, respectively, which were significantly higher than those in the control group ( P<0.05). ⑥ The CD123 DuAb significantly activated T cells, and the activation intensity was positively correlated with its concentration. The expression rate of CD107a on T cells reached 16.05% with 1 nmol/L CD123 DuAb, which was significantly higher than that of the control group ( P<0.05). ⑦The CD123 DuAb promoted cytokine secretion by T cells at a concentration of 1 nmol/L, and the concentration of IFN-γ and TNF-α in the supernatant of the co-culture system reached 193.8 pg/ml and 169.8 pg/ml, respectively, which was significantly higher than that of the control group ( P<0.05). ⑧When CD123 DuAb was added at a concentration of 1 nmol/L to the co-culture system of T cells and CD123 + tumor cells, the killing intensity of T cells significantly increased, and the residual rates of CD123 + MV4-11 cells, CD123 + Molm13 cells, and CD123 + THP-1 cells were 7.4%, 6.7%, and 14.6% on day 3, respectively, which were significantly lower than those in the control group ( P<0.05) . Conclusion:In this study, a novel CD123 DuAb was constructed and expressed. In vitro experiments verified that the DuAb binds to CD123 + tumor cells and T cells simultaneously, promotes T-cell activation and proliferation, and facilitates their anti-leukemia effect, which provides a basis for further clinical research.

Objective To identify the risk factors of new-onset hypertriglyceridemia (HTG) in kidney transplant recipients. Methods Clinical data of 149 kidney transplant recipients were retrospectively analyzed. According to serum triglyceride (TG) level after operation, they were divided into the non-HTG group (TG≤1.7 mmol/L, n=60) and new-onset HTG group (TG>1.7 mmol/L, n=89). Baseline data of all recipients were compared between two groups. The risk factors of HTG in kidney transplant recipients were analyzed by generalized estimating equation (GEE), and validated by multiple regression equations. Results No significant differences were observed in baseline data between two groups (all P>0.05). Multivariate analysis showed that the incidence of HTG in the middle and high tacrolimus (Tac) concentration groups was higher than that in the low Tac concentration group [odds ratio (OR) 3.11, 95% confidence interval (CI) 1.22-7.93, P=0.018 in the middle Tac concentration group; OR 5.11, 95%CI 1.31-19.98, P=0.019 in the high Tac concentration group]. Compared with type-A blood recipients, the risk of new-onset HTG was significantly increased in type-O blood counterparts (OR 2.77, 95%CI 1.14-6.71, P=0.024). The risk of new-onset HTG was decreased along with the increase of preoperative globulin level (OR 0.93, 95%CI 0.87-0.99, P=0.043). At postoperative 3 months, Tac blood concentration in the new-onset HTG group was significantly higher compared with that in the non-HTG group, and significant difference was observed (P<0.05). Multiple regression equations confirmed that the risk of new-onset HTG in type-O blood kidney transplant recipients was higher than that in type-A blood counterparts, and the risk of new-onset HTG in the middle and high Tac concentration groups was higher than that in the low Tac concentration group (all P<0.05). Conclusions Type-O blood kidney transplant recipients are more prone to HTG. It is necessary to strengthen postoperative monitoring and control of blood lipids. The blood concentration of Tac probably affects the new-onset HTG in kidney transplant recipients. Maintaining an appropriate blood concentration of Tac may be beneficial to lowering the risk of HTG.
