Objective To identify renal function and other readily accessible indicators influencing the prognosis of renal cell carcinoma (RCC) patients after nephrectomy, and to construct a prognostic prediction model based on them. Methods The clinical and pathological data of 624 RCC patients undergoing radical or partial nephrectomy in the First Hospital of Shanxi Medical University during Jan. 2013 and Dec. 2021 were retrospectively analyzed. The independent prognostic factors affecting postoperative overall survival (OS) were identified with LASSO algorithm combined with Cox regression analysis. Based on these factors, a nomogram was constructed to predict the 1-, 3-, and 5-year survival rates. The performance of the model was evaluated using the concordance index (C-index), time-dependent receiver operating characteristic (ROC) curves and the area under the curve (AUC), calibration plots, and decision curve analysis (DCA). Finally, the cutoff value of the nomogram was calculated to stratify patients into risk groups. Kaplan-Meier survival analysis with log-rank testing was performed to compare outcomes between the risk groups. Results Nine independent prognostic factors were identified, including age, smoking history, diabetes mellitus history, maximum tumor diameter, tumor subtype, N stage, Fuhrman grade, preoperative serum creatinine and cystatin C (P<0.05). The nomogram achieved a C-index of 0.891, with time-dependent AUC of 0.920, 0.903, and 0.867 for 1-, 3-, and 5-year OS, respectively. Calibration curves showed excellent agreement with actual observations, and DCA demonstrated significant clinical net benefits across a wide threshold probability range. Using a cutoff score of 110.4, Kaplan-Meier analysis revealed statistically significant survival differences between risk groups (P<0.001). Conclusion The proposed nomogram, incorporating renal function and other readily accessible clinical indicators, exhibits strong predictive accuracy for postoperative survival in RCC patients and may serve as a practical tool for individualized clinical decision-making.

AIM:To investigate the effect of peripheral defocus design rigid gas permeable contact lenses(defocus RGPCL)in controlling myopia progression in children aged 6-12 y with high myopia, and to compare the outcomes with traditional single-vision RGPCL and single-vision spectacles.METHODS:This prospective cohort study enrolled children aged 6-12 y with high myopia who visited the Ophthalmology and Optometry Center of Xi'an No.1 Hospital between January 2022 and January 2023. Based on parental preference, participants were divided into three groups: defocused RGPCL group, single-vision RGPCL group, and single-vision spectacles group. The axial length(AL)and cycloplegic spherical equivalent(SE)refraction were compared at baseline, 0.5, 1, 1.5, and 2 y after lens wear. Additionally, AL and SE delay rates were calculated for each group.RESULTS: This study enrolled a total of 90 children with high myopia(180 eyes), with no participants lost to follow-up. Participants were allocated into three groups based on parental preference. Thirty children(60 eyes)were assigned to the peripheral defocus RGPCL group, consisting of 12 boys and 18 girls with a mean age of 9.96±1.56 y; 30 children(60 eyes)to the single-vision RGPCL group, including 15 boys and 15 girls with a mean age of 9.40±1.52 y; and 30 children(60 eyes)to the single-vision spectacles group, with 14 boys and 16 girls and a mean age of 9.80±1.37 y. At 0.5, 1, 1.5, and 2 y lens fitting, AL and SE increased significantly in all three groups(all P<0.05), with the growth rates in the defocused RGPCL group being significantly lower than those in the single-vision RGPCL and single-vision spectacles groups(all P<0.05). At 2 y lens fitting, the AL elongation was 0.22±0.24 mm and the mean SE progression was 0.70±0.70 D in the peripheral defocus RGPCL group; 0.49±0.38 mm and 1.34±0.60 D in the single-vision RGPCL group; and 0.50±0.21 mm and 1.72±0.47 D in the single-vision spectacles group. Using the single-vision spectacles group as the control, the AL delay rate and SE delay rate at 2 y lens fitting were 56.0% and 59.3%, respectively, in the defocused RGPCL group.CONCLUSION:For children with high myopia aged 6-12 y, defocus RGPCLs can effectively and significantly delay AL elongation and SE progression, demonstrating markedly superior control efficacy compared to single-vision RGPCL or single-vision spectacles. Defocused RGPCL can serve as an effective optical intervention for high myopia children.

The NOD-like receptor protein 3(NLRP3)inflammasome is essential in innate immune-mediated inflammation,with its overactivation implicated in various autoinflammatory,metabolic,and neurode-generative diseases.Pharmacological inhibition of NLRP3 offers a promising treatment strategy for in-flammatory conditions,although no medications targeting the NLRP3 inflammasome are currently available.This study demonstrates that clioquinol(CQ),a clinical drug with chelating properties,effec-tively inhibits NLRP3 activation,resulting in reduced cytokine secretion and cell pyroptosis in both human and mouse macrophages,with a half maximal inhibitory concentration(IC50)of 0.478 μM.Additionally,CQ mitigates experimental acute peritonitis,gouty arthritis,sepsis,and colitis by lowering serum levels of interleukin-1β(IL-1β),IL-6,and tumor necrosis factor-α(TNF-α).Mechanistically,CQ covalently binds to Arginine 335(R335)in the NACHT domain,inhibiting NLRP3 inflammasome assembly and blocking the interaction between NLRP3 and its component protein.Collectively,this study identifies CQ as an effective natural NLRP3 inhibitor and a potential therapeutic agent for NLRP3-driven diseases.

Objective:To propose a deep learning(DL)-based ultrasound imaging auxiliary tool for automatic segmentation and recognition of the brachial plexus(BP),and to enhance the accuracy and safety of clinical procedures.Methods:It was a multicenter study that collected 773 healthy subjects from Peking University Third Hospital and its branch campuses,the Third Medical Center of the Chinese PLA General Hospital,and Shanghai Eighth People's Hospital between August 2024 and February 2025. Brachial plexus(BP)images in the interscalene groove were captured used high-frequency ultrasound by senior sonographers,a dataset comprising 1 289 standardized images were constructed and the improved model(CHA-TransUNet)was trained. The test set was input into 6 different models(CHA-TransUNet,R50-Unet,TransUnet,SegFormer,SwinUnet,MISSFormer)for segmentation. Segmentation accuracy was evaluated using metrics including the Dice similarity coefficient(DSC),95% Hausdorff distance(HD95)and mean intersection over union(mIoU),and was compared with the segmentation results of 3 ultrasound physicians with varying experience levels(junior physicians and senior physicians)to validate the model's segmentation efficacy.Results:The CHA-TransUNet model established based on a dataset of 1 289 standardized images achieved segmentation results for the BP with a DSC of 90.15%,mIoU of 91.02%,and HD95 of 8.08. Its accuracy was higher than other mainstream models(DSC:90.15% vs. 87.60%,87.77%,81.35%,84.78%,84.55%),significantly better than junior physicians(DSC:90.15% vs. 68.73%, Z=-127.76, P<0.001),and approached the level of senior physician(DSC:90.15% vs. 86.15%, Z=-31.33, P=0.549). The model demonstrated superior boundary recognition in complex anatomical structures(e.g.,C6/C7 nerve roots)compared to ultrasound physicians(junior and senior)(HD95:8.08 vs. 26.34,17.44,56.80). Conclusions:This study proposes an analysis model for BP ultrasound images,CHA-TransUNet. This model achieves segmentation and recognition of the BP with relatively complex pathways and structures. The model exhibits high accuracy and stability,outperforming current mainstream network models and junior physicians while approaching the performance level of senior physicians. It assists junior physicians or trainees in more accurately identifying and localizing the BP.
