Introduction: The aim of the study was to compare the efficacy of a flexible-tip ureteral access sheath (F-UAS) with a traditional non-flexible ureteral access sheath (T-UAS) in the treatment of renal lower calyx stones. Methods: This retrospective analysis included clinical data from patients with unilateral renal lower calyx stones who underwent treatment with either an F-UAS (cases from December 2023 to September 2024) or a T-UAS (cases from January 2023 to November 2023). Inclusion criteria were ages 18–75 years, lower pole kidney stones measuring 1–2 cm. The primary outcome was the immediate postoperative stone-free rate (SFR) on the first day post-surgery. Secondary outcomes included operative time, postoperative complications, postoperative hospital stay, and 3-month SFR. Results: A total of 132 patients were included in the study, with 63 in the F-UAS group and 69 in the T-UAS group. Baseline characteristics were comparable between groups. The F-UAS group demonstrated a significantly higher day-1 postoperative SFR (73.0% vs. 17.4%; p < 0.001). The overall complication rate was lower in the F-UAS group (p = 0.031), with a notably reduced incidence of postoperative fever. The F-UAS group also had a significantly lower basket usage rate (20.6% vs. 100%; p < 0.001). There were no significant differences in operative time or 3-month SFR between the groups (p = 0.097 and p = 0.354, respectively). Hospital stay and stone composition were also similar between groups. Conclusion: Compared to T-UAS, the use of F-UAS for retrograde intrarenal surgery in the treatment of renal lower calyx stones is associated with a higher day-1 SFR. Additionally, the F-UAS group demonstrated reduced basket usage and fewer postoperative complications.

To assess the alterations in the resting-state function connections between the two cerebral hemispheres in patients with optic neuritis (ON) and healthy controls (HCs). A total of 12 ON patients (six males and six females) and 12 HCs (six males and six females) who were highly matched for sex, age, and educational level were recruited. They underwent functional magnetic resonance imaging (fMRI), testing and brain activities were assessed using the degree centrality (DC) method. Correlation analysis between the mean DC values in specific brain areas and behavior performances was analyzed as well. Linear correlations between A anxiety scale (AS) and depression scale (DS) values and DC values in brain regions of patients with ON were also analyzed. The areas that showed a higher DC value in ON patients were the right angular gyrus and bilateral precuneus, while the left insula and left superior temporal gyrus (LSTG) were regions that presented a lower DC value in ON patients. A receiver operating characteristic (ROC) curve analysis confirmed the accuracy of the area under the curve (AUC) assessment. Linear analysis showed anxiety scale (AS) and depression scale (DS) values in the left insula were both negatively correlated with DC values, while best corrected visual acuity logMAR-R (BCVA logMAR-R) showed a negative correlation with DC in the LSTG. The study explores altered brain activities of specific regions in patients with ON. The results provide clues for revealing the underlying mechanism of ON development.

PurposeTo explore the value of tissue quantitative diffusion analysis of ultrasound elastography in the diagnosis of early-stage chronic kidney disease (CKD).MethodsThe observation group comprised 54 patients with early-stage CKD treated at Fuzhou No 7 Hospital, and the control group consisted of 40 healthy individuals who underwent physical examinations at the same hospital. The renal parenchyma of the participants were examined using ultrasonography, color Doppler ultrasonography, and tissue quantitative diffusion analysis of ultrasound elastography. Renal dimensions (diameter, thickness, and renal parenchyma thickness), interlobar artery blood flow parameters, and 11 elastic characteristic values were analyzed and compared between the two groups. The area under the receiver-operating characteristic (ROC) curve, cut-off values, sensitivity, and specificity were calculated using the ROC curve analysis.ResultsThere were no significant differences in the blood flow parameters of the interlobar artery and the dimensions of renal meridians between the two groups. In the observation group, the mean (MEAN) decreased, while the blue area ratio and skewness, increased, compared to the control group (p < 0.05). In addition, the ROC curve revealed that the blue area ratio, MEAN, and skewness had significant diagnostic value (the area under the curve > 0.7). Notably, the best cut-off value of the MEAN was found to be 106, indicating that a MEAN value less than 106 represented early-stage CKD. Also, this cutoff value had a sensitivity of 80% and a specificity of 81%.ConclusionTissue quantitative diffusion analysis of ultrasound elastography can quantitatively evaluate renal parenchymal damage in early-stage CKD using quantitative diffusion parameters, with the MEAN parameter, having a cutoff of 106, being particularly effective. This parameter and cutoff value offer a valuable tool for the early detection and diagnosis of CKD, potentially improving patient outcomes through earlier intervention.Clinical trial numberNot applicable.

Objective: To investigate the clinicopathological characteristics of primary pulmonary NUT carcinoma. Methods: A total of 7 cases of primary pulmonary NUT carcinoma were collected from Fujian Provincial Hospital (n=5), Fuzhou Taijiang Hospital (n=1) and Binzhou City People's Hospital of Shandong Province (n=1) from January 2021 to April 2023. The clinical, histopathological, and immunohistochemical features were analyzed, and NUT rearrangement were detected by fluorescence in situ hybridization (FISH) with break-apart probes. Results: Seven cases were all male with age ranging from 32 to 73 years. The main clinical manifestations were cough, expectoration and chest tightness. Microscopically, NUT carcinoma was composed of monotonous proliferation of primitive-appearing small-to-medium round cells, with few eosinophilic cytoplasm, arranged in solid sheets, nests or clusters. Abrupt keratinization was typically observed in 4 cases (4/7), with high mitotic activities and necrosis. Immunohistochemistry (IHC) showed that the tumors were positive for NUT (7/7), CK7 (4/4), CK5/6 (5/6), p40 (6/7). Ki-67 index were 30%-80%. NUT gene segregation (7/7) was detected by FISH break probes. Conclusions: Primary pulmonary NUT carcinoma is rare and highly malignant. Diagnosis depends on histopathology and IHC, with molecular detection as an adjunct for diagnosis. Pathologists should be aware of the clinicopathological characteristics to avoid misdiagnosis.

BackgroundHemoporfin-mediated photodynamic therapy (HMME-PDT) is reported to be effective and safe for port-wine stains (PWS). However, its efficacy is influenced by several factors and there is no appropriate method to evaluate efficacy so far. Therefore, this study explored the clinical efficacy of HMME-PDT for PWS on the face and neck and the feasibility of evaluating treatment potency with optical coherence tomography (OCT).MethodsA total of 211 PWS patients subjected to HMME-PDT were recruited for study and correlations of therapeutic effect with treatment sessions, age, gender, lesion distribution and treatment history analyzed. OCT was utilized for quantitative analysis of PWS lesions of 36 selected patients before and after HMME-PDT.ResultsThe efficacy of two consecutive treatments was significantly higher than that of single treatment (P < 0.05). In multivariate analysis, after the first treatment, age, lesion distribution and treatment history were correlative factors affecting treatment efficacy (P < 0.05). The improvement effect on central facial lesions was lower than that on lateral facial lesions (P < 0.05). The efficacy of therapy on the group with no history of pulsed dye laser (PDL) treatment was greater than that on effective and ineffective treatment groups (P < 0.05). After the second session, age remained the only factor correlated with efficacy (P < 0.05). Dilated vessel diameter and depth before and after treatment were significantly different (P < 0.05). With increasing treatment times, age was the most significant factor influencing treatment efficacy.ConclusionsOur collective findings indicate that HMME-PDT therapy is effective and safe for PWS and support the utility of OCT in objective assessment of the efficacy of HMME-PDT.

Malignant atrophic papulosis (MAP) is a life-threatening vasculopathy affecting the skin, gastrointestinal tract, central nervous system, pleural membrane, and pericardium. MAP carries a poor prognosis primarily because of its systemic involvement. It is extremely rare in children. Herein, we report a pediatric case of MAP with small bowel perforation and anticardiolipin antibody positivity.

Purpose: There is still lacking of highly sensitive and specific biomarkers for the prediction of hepatocellular carcinoma (HCC) early recurrence, which has hindered further improvement of the clinical outcomes. We aim to find highly sensitive and specific biomarkers for the prediction of HCC recurrence.Patients and methods: By using isobaric tags for relative and absolute quantitation (iTRAQ)-based multidimensional liquid chromatography-tandem mass spectrometry (2D LC-MS/MS) technique, we have quantitatively investigated and monitored the proteome alterations of a series of serum after radical resection during the follow-up of 4 HCC patients.Results: A total of 27 differentially abundant proteins (DAPs) in serum were identified to be closely associated with the early recurrence of HCC, and these DAPs were particularly concentrated within ERK1/2 and nuclear factor-κ beta signaling pathways, suggesting the dysregulation of these two pathways played an important role in the pathological process of HCC early recurrence. Further investigation of a cohort of patients confirmed that the high serum level of PGK1 was closely associated with HCC early recurrence and poor prognosis. In addition, the serum level of PGK1 could be complementary with AFP to further improve the sensitivity and specificity for predicting the relapse of HCC.Conclusion: PGK1 might be an independent factor for the recurrence of HCC. And the PGK1 could be complementary with AFP to further improve the sensitivity and specificity in prognostic prediction of HCC relapse.
