Objective To analyze the distribution characteristics of the single nucleotide polymorphism (SNP) site rs76206423 in the promoter region of the interleukin-2 receptor (IL-2R) β gene among Han males in a high radiation background area (HBRA) in Yangjiang City. Methods A total of 48 male participants from Tangkou Town, Yangxi County, Yangjiang City (HBRA group), and 51 male participants from Hengpo Town, Enping City (control group) were selected as the research subjects using the random number table method. Peripheral venous blood samples of participants from both groups were collected, and genomic DNA was extracted. The genotyping and allele frequency distribution of the rs76206423 (A/G) site in the IL-2R β promoter region was detected among the participants in both groups using the SNP detection method. The difference of allele frequencies between population in HBRA group and five area of East Asia, South Asia, Africa, Europe, and the Americas published in the Human Genome Project database from National Center for Biotechnology Information were analyzed. Results The allele frequencies of rs76206423 of population in both groups conformed to Hardy-Weinberg equilibrium (P>0.05). In the HBRA group, the AA genotype was predominant (64.6%), while the AG genotype was the most common in the control group (51.0%), with a significant difference (P<0.05). Population in both groups showed a predominance of the variant allele A (78.1% and 72.5%, respectively), with no significant difference (P>0.05). The frequency of the G allele of rs76206423 in the population in HBRA group was higher than those in South Asian, African, European, and American populations (all P<0.01), but showed no significant difference compared with East Asian populations (P>0.05). Conclusion In the Han male population from the HBRA in Yangjiang City, the rs76206423 site in the IL-2R β gene promoter region is predominantly composed of the wild-type A allele and AA genotype, indicating genetic stability and a relatively high degree of variation at this locus.

Objective: To compare and analyze the antibacterial effects of platelets against five common clinical pathogenic bacteria including MRSA, SE, SA, E. coli, and CRKP, and to preliminarily explore the role of DCD sensitivity in the observed variations of antibacterial effects. Methods: The same number of platelets were used to establish co-culture systems of platelets and platelet lysates with the five pathogenic bacteria. The antibacterial effects of platelets and platelet lysates on the five pathogenic bacteria were evaluated by observing the turbidity of the bacterial solution, measuring the OD value of the bacterial solution and counting the colonies. The supernatant protein of platelets co-cultured with MRSA was collected for quantitative proteomics analysis to explore the important antibacterial proteins of platelets. The content of DCD in the supernatant after co-culture of platelets and platelet lysates with the five pathogenic bacteria was detected by ELISA to preliminarily analyze the reasons for the different antibacterial effects of platelets on the five pathogenic bacteria. Results: Compared with the control group of MRSA, SA, and SE, the turbidity of the bacterial solution decreased after co-culture of platelets and platelet lysates with MRSA, SA, and SE for 12 h, and the OD value and colony count were significantly reduced (P<0.05). The turbidity of the bacterial solution did not change significantly after co-culture of platelets and platelet lysates with E. coli for 24 h, but the OD value decreased (P<0.05), and the colony count decreased to 10 CFU/mL but the difference was not statistically significant (P>0.05). Compared with the control group of CRKP, the turbidity, OD value, and colony count of the bacterial solution did not change significantly after co-culture of platelets and platelet lysates with CRKP (P>0.05). Proteomics results showed that after co-culture with MRSA, important proteins related to platelet activation, including collagen, fibrinogen, von Willebrand factor, integrin αIIbβ3, platelet glycoprotein V and IV were significantly up-regulated. ELISA results showed that after co-culture with the five pathogenic bacteria, platelets could secrete a large amount of DCD, with the content around 3 μg/mL. Conclusion: The antibacterial effect of platelets on Gram-positive bacteria MRSA, SA, and SE is better than that on Gram-negative bacteria E. coli and CRKP, and platelets have the best antibacterial effect on MRSA. The differences in antibacterial effects of platelets on the five pathogenic bacteria may be related to the sensitivity of DCD antibacterial peptides to the five pathogenic bacteria.

Objective:To evaluate long-term outcomes of endoscopic papillectomy (EP) for duodenal papillary adenomas and to identify risk factors for incomplete resection.Methods:Clinical data of 180 patients diagnosed as having duodenal papillary adenoma via postoperative pathology after EP in Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School from January 2010 to December 2022 were retrospectively analyzed. Patients were divided into two groups based on their postoperative margin status: the complete resection group (negative resection margins) and the incomplete resection group (positive/uncertain resection margins). Recurrence rates were compared between the two groups, and logistic regression analysis was performed to identify risk factors for incomplete resection.Results:Among the 180 patients included in the study, 137 underwent complete resection, and 43 had incomplete resections. Recurrence rate was significantly higher in the incomplete resection group than that in the complete resection group (30.2% VS 15.3%, χ2=4.75, P=0.029). logistic regression analysis indicated that high-grade intraepithelial neoplasia was an independent risk factor for incomplete resection ( OR=2.43, 95% CI:1.12-5.26, P=0.024). Conclusion:Patients with incomplete resection after EP have a higher recurrence rate in the long-term follow-up. High-grade intraepithelial neoplasia is an independent risk factor for incomplete resection. Close surveillance and aggressive management are warranted for patients with positive or uncertain resection margins to mitigate the recurrence risk.

Objective:To compare the clinical efficacy of direct versus double-balloon occlusion in endoscopic ultrasound-guided gastroenterostomy (EUS-GE) for benign and malignant gastric outlet obstruction (GOO).Methods:Clinical data of patients with GOO who underwent EUS-GE at Nanjing Drum Tower Hospital between April 2017 and July 2024 were analyzed in a retrospectively cohort study. The patients were divided into the direct technique group ( n=36) and the double-balloon occlusion technique group ( n=105). The technical success rate, clinical success rate, procedure time, postoperative stay, stent replacement rate, and incidence of adverse events were compared between the two groups. Results:The technical success rates of the two groups were comparable, 97.2% (35/36) and 94.3% (99/105) ( χ2=0.065, P=0.798), so were the clinical success rates, 94.4% (34/36) and 86.7% (91/105) ( χ2=0.932, P=0.334). However, the direct technique group demonstrated significantly shorter procedure time and postoperative stay compared to the double-balloon occlusion group [33.4 (23.2, 42.3) min VS 43.4 (31.7, 63.1) min, Z=-3.057, P=0.002; 4.0 (3.00, 5.75) days VS 6.0 (5.00, 9.00) days, Z=-4.031, P<0.001]. Adverse event rates [11.1% (4/36) VS 11.4% (12/105), χ2<0.001, P=1.000] and stent replacement rates [5.6% (2/36) VS 9.5% (10/105), χ2=0.152, P=0.696] showed no significant differences. Conclusion:Both EUS-GE techniques achieve comparable efficacy and safety for GOO. However, the direct technique showed significant advantages over the double-balloon occlusion technique in terms of shorter procedure time and reduced postoperative hospital stay.

Objective To mine the risk signals of adverse drug events(ADEs)related to lecanemab through the U.S.Food and Drug Adminstration Adverse Event Reporting System(FAERS)database,to provide a reference for the safe clinical use of lecanemab.Methods Data on adverse events related to lecanemab from the fourth quarter,2010 to the second quarter 2024 in the FAERS were collected.Potential ADE signals were mined using the reporting odds ratio(ROR)method,Medicines and Healthcare Products Regulatory Agency(MHRA)method,Bayesian confidence propagation neural network(BCPNN)method and multi-item gamma Poisson shrinker(MGPS)method.The top 30 ADEs in terms of report frequency and signal strength,as well as ADEs categorized by system organ class(SOC),were statistically analyzed.Results A total of 868 adverse event reports related to lecanemab were collected,involving 1,986 instances of ADEs with 38 related ADE identified,the proportion of serious ADEs was 23.39％,and 87.15％of ADEs occurred in the first 3 months after the initiation of the drug.The top 30 PT signals in reported cases were headache,chills,fatigue,effusion type amyloid-related imaging abnormalities(ARIA-E),hemorrhage-type amyloid-related imaging abnormalities(ARIA-H),and so on.The top 30 signals in terms of signal intensity mainly included ARIA-E,ARIA-H,brain fog,infusion-related reactions.ADEs related to nervous system diseases were the most common.Fifteen new suspected or serious ADEs not recorded in the instructions were discovered,such as brain fog,formication,status epilepticus.Conclusion Risk assessment of patients'medication should be conducted before clinical use of lecanemab,especially in the first 3 months of the medication period,focus should be placed on monitoring common ADEs,such as ARIA-E,ARIA-H,infusion-related reactions.Attention also needs to be paid to the newly discovered suspected ADEs,to ensure the patients'medication safety.
