Bladder urothelial carcinoma is one of the common malignant tumors of the urinary system.The traditional treatment is transurethral resection of bladder tumor (TURBT)，which is mainly used for non-muscle invasive bladder cancer.However，this surgical procedure has problems such as fragmented specimens，inaccurate staging，and high incidence of complications.With the development of surgical techniques and equipment，en bloc resection of bladder tumor (ERBT) is gradually replacing traditional TURBT thanks to advantages of minimal trauma，fewer complications，and so on.ERBT based on various types of lasers provides clinicians with multiple choices，such as neodymium laser，holmium laser，thulium laser，blue laser，and diode laser.However，lasers have different advantages as well as limitations.This paper explores the current application of various lasers in ERBT，and analyzes the challenges and plans in handling large volume bladder tumors and collecting specimens，so as to provide reference for clinical urologists.

Objective:From the perspective of patients'emotions,to compare and study the effectiveness between experiential communication and GLTC communication of outpatient doctors,understand the main communication details that affect patients'emotions,and provide a reference for improving patient emotions and enhancing doctor-patient communication skills in the future.Methods:From July 2021 to January 2022,a pilot study of GLTC communication program in outpatient settings was conducted in a total of 24 departments from 4 tertiary comprehensive hospitals in Jiangsu Province.Descriptive analysis,independent sample t-test,multiple linear regression and other analyses were conducted on the relevant data.Results:After experiential communication in outpatient settings,patients showed improvements in dimensions of emotion such as anxiety,fatigue,confusion,and depression,but there was a decrease in patient vitality(P<0.05).After GLTC communication in outpatient settings,patients'emotions in all six dimensions improved(P<0.05).Meanwhile,the GLTC group had better emotions than the experiential group after communication(P<0.05).After training,the completion rate of relevant communication details of doctors in the GLTC group was mostly significantly higher than that in the experiential within the same unit time(P<0.05).Multiple linear regression showed that smiling,comforting language,and kind gaze were the main factors affecting patients'overall emotions.Conclusion:Experiential communication in outpatient settings has certain communication effects,but there is still a lot of room for improvement compared to GLTC communication in outpatient settings.GLTC communication in outpatient settings can improve patients'emotions,and doctors'smiles,comforting language,and other communication details need to be emphasized in outpatient settings.How to improve the execution of GLTC communication in outpatient settings plans is an important direction for future research.

[Objective] To explore the cellular composition and gene expression characteristics of adrenocortical adenoma (ACA) based on single-nuclear RNA sequencing. [Methods] The postoperative resection samples of 2 ACA cases treated at our hospital during Jul.and Aug.2022 were collected.The cellular composition was isolated and identified with single-nuclear RNA sequencing, the adrenal cortical subgroups were subdivided with specific cortical cell subgroup markers, and the characteristic gene expression profile was studied. [Results] The main components of ACA were adrenal cortical cells (78.62%), endothelial cells (1.91%), fibroblasts (3.09%), macrophages (14.34%), and T cells (2.05%). Subdivision of cortical cells revealed a group of undefined cells (1.08%), in addition to zona glomerulosa (ZG) cells (1.77%), zona fasciculata (ZF) cells (94.98%), and zona reticularis (ZR) cells (2.17%). These undefined cells were characterized by high expression of intercellular adhesion molecule 1, growth arrest and DNA damage inducing proteins β, tumor necrosis factor α inducing protein 3 and CD36 molecules.According to correlation analysis of the gene expression, these undefined cells were similar to the ZF cells.DEGs enrichment analysis indicated that the metabolic process enrichment index was the highest in biological processes.Reactome GO enrichment analysis revealed that the immune system cytokine signaling response was the most significant.KEGG signaling pathway analysis showed that Th17 cell differentiation pathway was the mostly enriched.DEGs were found to be most closely related to viral infection by DO enrichment analysis. [Conclusion] This study reveals for the first time the gene expression profile characteristics of cell subset in ACA, which can provide reference to explore the mechanism of ACA.

Objective:To investigate the clinical characteristics and the efficacy of thrombus aspiration in patients with early intrastent thrombosis (EST) following carotid artery stenting (CAS).Methods:This study is a retrospective case series, collecting clinical data of five patients who developed EST after CAS in the Department of Neurosurgery, Beijing Chaoyang Hospital, Capital Medical University from January 2021 to September 2023.All patients were male, with an age of (64.0±11.9) years (range:48 to 77 years), accounting for 2.0% (5/244) of CAS procedures during the same period.Among them, three patients did not receive standard dual antiplatelet therapy before the procedure, and one had an inadequate ADP inhibition rate (45.6%).Four patients received XACT carotid stents, while one received a Wallstent carotid stent.All five patients showed significant residual stenosis ranging from 43% to 55% after CAS.Emergency thrombus aspiration was performed in all cases, and data regarding perioperative conditions, vascular patency, and clinical outcomes were collected.Results:The interval between CAS and the occurrence of EST ranged from 3 hours to 14 days.The main clinical symptoms included sudden onset of consciousness disorders and contralateral limb weakness.None of the patients received preoperative intravenous thrombolysis, and thrombus aspiration was performed during the procedure to restore vascular patency.Four cases underwent balloon angioplasty during the procedure, and two cases utilized overlapping stents.Two patients experienced intraoperative embolization of thrombus to the C 2 segment.In one case, the embolized thrombus was retrieved using an intracranial thrombectomy stent, while in another case, it was aspirated using a guiding catheter.Postoperatively, all patients had a thrombolysis in cerebral infarction grade of 3, and symptoms improved in four cases.One patient showed no improvement in symptoms, and MRI revealed extensive new infarction in the right frontal and insular regions, adjacent to the right lateral ventricle.Regular follow-up examinations after discharge did not reveal restenosis or embolism within the stent.The follow-up period ranged from 7.6 to 21.2 months, with modified Rankin scale scores of 0 to 1 point in four cases and 2 points in one case, indicating good recovery in all patients. Conclusions:Acute intrastent thrombosis is a rare complication after carotid artery stenting.The combined use of percutaneous thrombus aspiration and endovascular techniques, such as balloon angioplasty and stent overlapping, can rapidly restore vessel patency with favorable outcomes.However, further large-scale clinical studies are needed to confirm the effectiveness of these treatments for acute intrastent thrombosis.

Purpose To study the clinical and pathological features of angiomatoid fibrous histocytoma(AFH)and to ex-plore its diagnosis,differential diagnosis and prognosis.Meth-ods The clinicopathological and follow-up data were analyzed in 14 cases of AFH,and the literatures were reviewed.Results There were 11 males and 3 females.The age ranged from 11 months to 12 years and 11 months,with average 5.9 years.3 cases were located in limbs,and 5 cases in trunk,5 cases in head and neck region,and 1 of intracranial tumor.Histological-ly,14 cases were composed of fibrous capsules and lymphocyte sheaths,and cell nucleus were vacuolar,forming fascicles with focal whirling and synteny.Intralesional pseudoangiomatous spaces were noted in 9 cases.Calcification was found in 2 ca-ses.2 cases showed high mitotic acticity(11/10 HPF).Scle-rosing and/or myxoid stroma was seen in 3 cases.Tumors were immunopositive for desmin(10/14),EMA(12/14),CD99(12/14),SMA(9/12),ALK(7/8),and the average of Ki67 index was 16％.7 cases harbored EWSR1 rearrangenent(part-ner gene not identified),2 cases had EWSR1-ATF1 fusion and 2 EWSR1-CREB1 fusion.Clinical follow-up information was a-vailable for 14 cases(average 46 months).All the 14 cases were alive without recurrence and metastasis.Conclusion AFH is a borderline or low-grade malignant tumor,often demon-strates indolent behavior in children,but rarely recurs and me-tastasizes.The diagnosis and differential diagnosis require a comprehensive analysis of clinical features,histopathologic changes,immunohistochemical finding and EWSR1 or FUS gene detection results.

Background::Renal ischemia-reperfusion (R-I/R) injury is the most prevalent cause of acute kidney injury, with high mortality and poor prognosis. However, the underlying pathological mechanisms are not yet fully understood. Therefore, this study aimed to investigate the role of N-myc downstream-regulated gene 2 ( Ndrg2) in R-I/R injury. Methods::We examined the expression of Ndrg2 in the kidney under normal physiological conditions and after R-I/R injury by immunofluorescence staining, real-time polymerase chain reaction, and western blotting. We then detected R-I/R injury in Ndrg2-deficient ( Ndrg2-/-) mice and wild type ( Ndrg2+/+) littermates in vivo, and detected oxygen and glucose deprivation and reperfusion (OGD-R) injury in HK-2 cells. We further conducted transcriptomic sequencing to investigate the role of Ndrg2 in R-I/R injury and detected levels of oxidative stress and mitochondrial damage by dihydroethidium staining, biochemical assays, and western blot. Finally, we measured the levels of mitophagy in Ndrg2+/+ and Ndrg2-/- mice after R-I/R injury or HK-2 cells in OGD-R injury. Results::Ndrg2 was primarily expressed in renal proximal tubules and its expression was significantly decreased 24 h after R-I/R injury. Ndrg2-/- mice exhibited significantly attenuated R-I/R injury compared to Ndrg2+/+ mice. Transcriptomics profiling showed that Ndrg2 deficiency induced perturbations of multiple signaling pathways, downregulated inflammatory responses and oxidative stress, and increased autophagy following R-I/R injury. Further studies revealed that Ndrg2 deficiency reduced oxidative stress and mitochondrial damage. Notably, Ndrg2 deficiency significantly activated phosphatase and tensin homologue on chromosome ten-induced putative kinase 1 (PINK1)/Parkin-mediated mitophagy. The downregulation of NDRG2 expression significantly increased cell viability after OGD-R injury, increased the expression of heme oxygenase-1, decreased the expression of nicotinamide adenine dinucleotide phosphate oxidase 4, and increased the expression of the PINK1/Parkin pathway. Conclusion::Ndrg2 deficiency might become a therapy target for R-I/R injury by decreasing oxidative stress, maintaining mitochondrial homeostasis, and activating PINK1/Parkin-mediated mitophagy.

Exosomes are nanoscale particles secreted by various cells,including immune,stem,and tumor cells.They are enriched with bio-active substances that transport tumor information,mediate intercellular communication,and regulate multiple physiological processes and tumor microenvironment(TME)remodeling.Exosomes secreted by different tumor cell types exhibit cell-specific characteristics,contain various factors involved in immune regulation,and can interact with all types of immune cells.Cancer immunoediting is a process in which the immune system can both constrain and promote tumor development,involving three phases:elimination,equilibrium,and escape.Tu-mor-derived exosomes play diverse roles during these stages,both promoting anti-tumor immunity and inhibiting the anti-tumor activity of immune cells.Collectively,understanding the immunoediting role of exhausted T cells(TEXs)in regulating the immune microenvironment in lung cancer provides novel insights into antitumor therapy.

Female acquired urinary incontinence is a clinical challenge. This article reported a female patient who had urinary incontinence after excessive urethral caruncle resection. Urodynamics showed effective urethral length was 1.6 cm and maximal urethral pressure was 41 cm cmH 2O(1 cmH 2O=0.133 kPa). Urethroscopy showed urethral length was about 2 cm, urethral sphincter function was good, and urethral stricture was absent. The patient has undergone robot-assisted modified Leadbetter bladder neck reconstruction. The surgery was successfully completed without intraoperative complications. Urinary catheter was removed at 4 weeks after surgery, and the patient has complete urinary continence with unobstructed voiding. After 3 months of follow-up, the patient still has unobstructed voiding and urinary continence.

Objective:To evaluate the efficacy of robot-assisted Y-V plasty (RAYV) and laparoscopic Y-V plasty (LYV) in the treatment of refractory bladder neck contracture (BNC) after BPH surgery.Methods:A retrospective analysis was performed for the clinical data of 42 patients with refractory BNC after BPH surgery from January 2020 to July 2023, including 18 RAYV and 24 LYV. There were no significant differences between both groups( P>0.05) in term of median age [68(62, 81) years vs. 70(61, 76) years], median body mass index [20.7(17.6, 26.1) kg/m 2 vs. 19.8(16.3, 25.3) kg/m 2], median Q max [9.4(5.6, 13.2) ml/s vs. 8.9(6.2, 12.2)ml/s], median IPSS [20.5(15, 23) vs. 21.1(17, 23)], median QOL score [4.6 (4, 6) points vs. 4.8 (4, 6) points] and median postvoid residual volume [84.7(58, 125)ml vs. 78.3(50, 120)ml]. Preoperative examination of one patient in the RAYV group showed no contractile function of the external urethral sphincter.The surgical procedure was basically the same for both groups: entering into the retropubic space, and incision of the anterior wall of bladder and prostate urethra was performed in an inverted Y-shaped. After excising the scar around the anterior wall of bladder neck, the apex of inverted V-shaped bladder wall flap is brought to the base of the Y-shaped incision using two 3-0 running suture. The catheter was removed 2 weeks after surgery. Perioperative and follow-up data were compared between the two groups. Results:All surgeries were successfully completed without complications. The difference between RAYV and the LYV group in operation time [71.8(50, 98)min vs. 105.9(71, 143)min] and postoperative drainage removal time [2.7(2, 4)d vs. 4.5(3, 7)d] was statistically significant ( P<0.05). There was no significant difference between both groups in term of intraoperative blood loss [50.4(20, 100) ml vs. 60.8(40, 150) ml] and postoperative hospital stay [4.1(3, 5)d vs. 4.6(3, 7)d]( P>0.05). All patients were followed up with a median follow-up of 16.5(2, 41) months. There was no significant difference between RAYV and LYV in term of postoperative Q max [27.9(11.7, 37.6) ml/s vs. 22.4(12.3, 31.5)ml/s], IPSS[5.1(4, 9) points vs. 4.8(4, 10) points], QOL[1.6(1, 3) points vs. 1.5(1, 3) points] and postvoid residual volume [5.6(0, 15) ml vs. 7.2(5, 20) ml] ( P>0.05). The postoperative bladder neck patency rates in the RAYV group and the LYV group were 94.4%(17/18) and 95.8%(23/24), respectively, with no significant difference( P>0.05). In terms of urinary continence, 1 patient in the RAYV group had no contractile function of the external urethral sphincter before surgery, and none of the 41 patients with good preoperative continence had urinary incontinence after surgery. Conclusions:The effect of RAYV in the treatment of refractory BNC after BPH surgery is comparable to that of LYV, but RAYV can shorten the operation time and postoperative drainage time.
