Objective To discuss the mechanism of the streaking artifact of Star-volumetric interpolated body examination(Star-VIBE)sequence and the influence of phase coding on it.Methods Twenty-six volunteers underwent many times Star-VIBE sequences scanning with different phase coding(320,640,960,1 280,1 600).The severity of streaking artifact of images in different phase cod-ing groups was evaluated qualitatively.The signal-to-noise ratio(SNR)of muscle,thyroid and contrast-enhanced artery,contrast-to-noise ratio(CNR)between soft tissues,and CNR between muscle and contrast-enhanced artery of the images in different phase coding groups were evaluated quantitatively.Results In qualitative evaluation,with the number of phase coding increased,the streaking artifact decreased(H=83.022,P<0.005).In quantitative evaluation,SNRmuscle,SNRthyroid,SNRcontrast-enhanced artery and CNRcontrast-enhanced gradually increased with the increase of phase coding number(SNRmuscle:F=6.913,P<0.005;SNRthyroid:F=3.930,P=0.005;SNRcontrast-enhanced artery:F=6.980,P<0.005;CNRcontrast-enhanced:F=6.482,P<0.005),while CNRsoft tissue showed no statistical difference(F=1.114,P=0.339).Conclusion There is streaking artifact on the image of the Star-VIBE sequence,which can be reduced by increas-ing the number of phase coding appropriately.The most suitable phase coding is 960.

Objective To discuss the causes and the therapeutic strategy of acute cardiac tamponade(ACT)occurring as a complication of transcatheter aortic valve replacement(TAVR)so as to improve the success rate of the surgery and to make a further understanding of this complication.Methods The general clinical data,surgical procedures,and postoperative follow-up results of five patients,who received TAVR at the Affiliated Northern Jiangsu People's Hospital of Yangzhou University of China and developed ACT from March 2018 to September 2024,were retrospectively analyzed.Results After developing ACT,all the 5 patients received pericardiocentesis together with other adjuvant therapies including blood volume expansion with infusion,vasopressors,heparin neutralization,and blood transfusion.However,due to no obvious reduction in drainage volume and unstable hemodynamics all the 5 patients had eventually to receive open-chest surgery to identify the source of bleeding and to make hemostasis.Surgical exploration revealed that the perforation or rupture of cardiac structures caused by the temporary pacemaker lead or a super-stiff guide wire during the procedure was the main cause of ACT.Finally,after active treatment four patients recovered and discharged,and one patient died.The discharged patients were followed up for 3-12 months,and no procedure-related complications such as acute coronary artery occlusion,severe arrhythmia,exacerbation of heart failure symptoms,valve displacement,or stroke occurred.Conclusion As a severe complication occurring during the TAVR procedure,ACT requires to get a rapid diagnosis and management.Improvement of surgical techniques and operative methods,comprehensive preoperative assessment,and close intraoperative monitoring are crucial points for the prevention of ACT.

T-cell acute lymphoblastic leukemia (T-ALL) is a highly aggressive hematologic malignancy with a poor prognosis, despite advancements in treatment. Many patients struggle with relapse or refractory disease. Investigating the role of the super-enhancer (SE) regulated gene ubiquitin-specific protease 20 (USP20) in T-ALL could enhance targeted therapies and improve clinical outcomes. Analysis of histone H3 lysine 27 acetylation (H3K27ac) chromatin immunoprecipitation sequencing (ChIP-seq) data from six T-ALL cell lines and seven pediatric samples identified USP20 as an SE-regulated driver gene. Utilizing the Cancer Cell Line Encyclopedia (CCLE) and BloodSpot databases, it was found that USP20 is specifically highly expressed in T-ALL. Knocking down USP20 with short hairpin RNA (shRNA) increased apoptosis and inhibited proliferation in T-ALL cells. In vivo studies showed that USP20 knockdown reduced tumor growth and improved survival. The USP20 inhibitor GSK2643943A demonstrated similar anti-tumor effects. Mass spectrometry, RNA-Seq, and immunoprecipitation revealed that USP20 interacted with hypoxia-inducible factor 1 subunit alpha (HIF1A) and stabilized it by deubiquitination. Cleavage under targets and tagmentation (CUT&Tag) results indicated that USP20 co-localized with HIF1A, jointly modulating target genes in T-ALL. This study identifies USP20 as a therapeutic target in T-ALL and suggests GSK2643943A as a potential treatment strategy.

Objective To evaluate the efficacy of transurethral resection of bladder tumor(TURBT)in treating cystitis glandularis(CG),and to explore the influencing factors.Methods A retrospective analysis was conducted on 243 CG patients treated with TURBT during Jan.2013 and Dec.2020 in our hospitals.Postoperative efficacy was assessed using global response assessment(GRA).The correlation between GRA score and the demographic characteristics,comorbidities,initial complaints,and postoperative recurrence was determined with logistic regression analysis.Results Among the 243 patients,3.70%(9/243)had dysplasia,2.47%(6/243)had exuberant hyperplasia of Brinell's nest,and 2.06%(5/243)had intestinal metaplasia.The mean GRA score was(2.02±0.72)after a follow-up of(47.10±28.53)months.Re-operation was performed in 10.29%(25/243)of the patients due to recurrence,and the improvement of hydronephrosis and dysuria was 70.59%(12/17)and 50.00%(15/30),respectively.Pelvic fat increase developed in 1 patient(0.41%)after surgery.Logistic regression analysis showed that postoperative GRA score was not significantly correlated with demographic characteristics,body mass index,comorbidities,alcoholism and postoperative recurrence(P>0.05).Conclusion TURBT is an effective method in the treatment of CG,which can significantly improve patients'hydronephrosis and dysuria.However,approximately 10%of the patients experience recurrence,necessitating further surgery,which suggests the need for vigilance regarding potential recurrence during treatment.

Objective:
Hypertrophy ligamentum flavum (LFH) is a common cause of lumbar spinal stenosis, resulting in significant disability and morbidity. Although long noncoding RNAs (lncRNAs) have been associated with various biological processes and disorders, their involvement in LFH remains not fully understood.
Methods:
Human ligamentum flavum samples were analyzed using lncRNA sequencing followed by validation through quantitative real-time polymerase chain reaction. To explore the potential biological functions of differentially expressed lncRNA-associated genes, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were performed. We also studied the impact of lncRNA PARD3-AS1 on the progression of LFH in vitro.
Results:
In the LFH tissues when compared to that in the nonhypertrophic ligamentum flavum (LFN) tissues, a total of 1,091 lncRNAs exhibited differential expression, with 645 upregulated and 446 downregulated. Based on GO analysis, the differentially expressed transcripts primarily participated in metabolic processes, organelles, nuclear lumen, cytoplasm, protein binding, nucleic acid binding, and transcription factor activity. Moreover, KEGG pathway analysis indicated that the differentially expressed lncRNAs were associated with the hippo signaling pathway, nucleotide excision repair, and nuclear factor-kappa B signaling pathway. The expression of PARD3-AS1, RP11-430G17.3, RP1-193H18.3, and H19 was confirmed to be consistent with the sequencing analysis. Inhibition of PARD3-AS1 resulted in the suppression of fibrosis in LFH cells, whereas the overexpression of PARD3-AS1 promoted fibrosis in LFH cells in vitro.
Conclusion
This study identified distinct expression patterns of lncRNAs that are linked to LFH, providing insights into its underlying mechanisms and potential prognostic and therapeutic interventions. Notably, PARD3-AS1 appears to play a significant role in the pathophysiology of LFH.
