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.

Objective: To assess the awareness and associated factors of wild mushroom poisoning among students in Guizhou Province, so as to provide a scientific foundation for wild mushroom poisoning prevention and control among students. Methods: By a multi stage stratified cluster random sampling method, 1 162 students from Guizhou Province were selected in May 2024. The questionnaire survey was administered to evaluate knowledge regarding wild mushroom poisoning. Data were analyzed employing the χ 2 test and Logistic regression model. Results: Among the nine questions assessing awareness of wild mushroom poisoning, only three had the awareness rate exceeding 70%. Binary Logistic regression analysis revealed that students who "actively learn about the prevention of wild mushroom poisoning" ( OR=0.48, 95%CI =0.26-0.92) and "spread knowledge about wild mushroom poisoning to others" ( OR=0.47, 95%CI =0.33-0.69) scored higher on the wild mushroom poisoning knowledge questions ( P <0.05). Conversely, students with a habit of consuming wild mushrooms ( OR=1.52, 95%CI =1.15-2.02) scored lower ( P < 0.05 ). 42.3% of the students suggested that scientific dissemination and publicity about wild mushrooms should be intensified. Conclusions The awareness rate of wild mushroom poisoning knowledge among students in Guizhou Province requires further attention. Comprehensive knowledge should be disseminated systematically through various channels to further improve students awareness of the prevention and control of wild mushroom poisoning.

OBJECTIVE To evaluate the efficacy and safety of rituximab （RTX） in the treatment of primary Sjögren syndrome （pSS）. METHODS Randomized controlled trials （RCTs） on the effects of RTX （trial group） versus placebo （control group） in the treatment of pSS were searched from the Cochran Library， PubMed， Embase， Medline， Web of Science， VIP， CNKI， Wanfang， and other databases during the inception to February 2024. After literature screening and quality evaluation， meta-analysis was performed by using RevMan 5.3 software. RESULTS Seven RCTs were finally included， involving a total of 518 patients. Results of meta-analysis showed that European League Against Rheumatism Sjögren syndrome disease activity index （ESSDAI） score [MD＝－1.17， 95%CI（－1.52， －0.82）， P＜0.000 01] and oral dryness visual analogue scale （VAS） score [MD＝－3.97， 95%CI （－5.08， －2.86）， P＜0.000 01] in the trial group were significantly lower than the control group； unstimulated salivary flow rate [SMD＝0.64， 95%CI（0.41， 0.87）， P＜0.000 01] and Schirmer score [MD＝0.19， 95%CI（0.18， 0.20）， P＜0.000 01] were significantly higher than the control group. There was no statistical significance in response rate [RD＝0.10， 95%CI（－0.04， 0.23）， P＝0.16]， fatigue VAS score [MD＝－12.50， 95%CI（－35.14， 10.15）， P＝0.28]， European League Against Rheumatism Sjögren syndrome patient reported index （ESSPRI） score [MD＝0.33， 95%CI（－0.53， 1.18）， P＝0.46]， Short-form 36 health survey physical component summary （SF36-PCS） score [MD＝0.90， 95%CI（－2.97， 4.78）， P＝0.65]， SF-36 mental component summary （SF36-MCS） score [MD＝0.11， 95%CI（－0.41， 0.63）， P＝0.68]， total salivary gland ultrasound score [SMD＝－1.91， 95%CI（－4.01， 0.19）， P＝0.07] or the incidence of adverse drug reactions [OR＝1.15，95%CI（0.62，2.13），P＝0.66] between 2 groups. CONCLUSIONS RTX has advantages in the improvement of ESSDAI score， unstimulated salivary flow rate， Schirmer score and oral dryness VAS score in pSS patients， and has a good safety profile. However， it did not exhibit significant improvement in fatigue VAS score， ESSPRI score， SF36-PCS score， SF36-MCS score or response rates.

Objective:To discuss the optimal doping concentration of vanadium(V)and silicon(Si)co-doped TiO? coating(V-Si TiO?)formed on titanium surface by electrochemical treatment,to evaluate its antibacterial effect under visible light irradiation,and to clarify its visible light response mechanism.Methods:The medical pure titanium sheets were subjected to micro-arc oxidation followed by high-temperature calcination,and V-Si TiO2 coatings with different doping concentrations were prepared by adjusting the ratio of V to Si in the electrolyte.The experiment was divided into 1V:10Si(V5Si50)group,2V:10Si(V10Si50)group,and 3V:10Si(V15Si50)group;control group was set up(contains only bacterial culture medium).The optimal doping concentration was screened based on comprehensive evaluation of surface morphology,ion release,photocatalytic ability,and biocompatibility;cell counting kit-8(CCK-8)method was used to detect the proliferation activities and the survival rates of the cells in various group.Subsequently,the optimized coating was characterized and compared by scanning electron microscope(SEM),atomic force microscopy(AFM),digital eddy current coating thickness gauge,X-ray diffraction(XRD),X-ray photoelectron spectroscope(XPS),and ultraviolet-visible absorption spectroscopy(UV-vis).The experiment was divided into PT group(blank control),PEO group(no element doping),V10 group(V doping),Si50 group(Si doping),and V10Si50 group(2V:10Si).The ability of the coating materials to degrade methylene blue(MB)and generation of reactive oxygen species(ROS)under visible light were detected.For antibacterial experiments,Staphylococcus aureus(S.aureus)and Escherichia coli(E.coli)were used.The colony counts on plates in various groups were recorded after visible light irradiation for 2 h and dark treatment for 2 h,respectively.The ROS levels were detected using 2',7'-dichlorofluorescein diacetate(DCFH-DA)ROS probe.ROS scavenging experiment was performed using the optimal doping concentration V10Si50 group,and the two kinds of bacteria were divided into blank control group,N-acetylcysteine(NAC)group,V10Si50 group,and NAC+V10Si50 group.The colony counts on plates in various groups were recorded after visible light irradiation for 2 h.Results:The V concentration of 0.01 mol·L?1 and Si concentration of 0.05 mol·L?1 in the electrolyte solution were the optimal doping concentrations for the V-Si TiO? coating.The SEM observation results showed that compared with V5Si50 group and V15Si50 group,the surface pore size of the coating material in V10Si50 group was significantly decreased(P<0.05),and the coating thickness was significantly increased(P<0.05);its crystal structure was mainly anatase type,and the MB degradation rate of the coating material in V10Si50 group after 9 h of visible light catalysis was significantly increased(P<0.05).Compared with control group,the cell proliferation activity and cell survival rate in V10Si50 group were significantly increased at 1,2,and 4 d of cell culture(P<0.05);at 2 and 4 d of cell culture,the cell proliferation activity and cell survival rate in V5Si50 group and V15Si50 group were significantly decreased(P<0.05).Compared with PT,PEO,and Si50 groups,the colony counts of two kinds of the bacteria in V10 group and V10Si50 group after visible light irradiation for 2 h were significantly decreased(P<0.05).Compared with PT group and PEO group,the ROS levels in two kinds of the bacteria in V10Si50 group after 2 h of irradiation were significantly increased(P<0.05).Compared with V10Si50 group,the colony counts of two kinds of the bacteria in NAC+V10Si50 group were significantly increased(P<0.05).Conclusion:A reasonably loaded V-Si TiO? coating material(V10Si50)was screened out,which maintained good biological activity and significantly enhanced the antibacterial effect under visible light irradiation.

[Purpose]To analyze the trends of brain tumor incidence and age of onset in cancer registration areas of Jiangsu Province from 2009 to 2019.[Methods]The incidence data of brain tumors from 2009 to 2019 were obtained from 16 national cancer registration areas of Jiangsu Province.The crude incidence rate,age-standardized incidence rate by Chinese standard popula-tion(ASIRC),average age of onset,standardized age-specific incidence rate,and annual average percentage change(AAPC)by sexes and regions were calculated.[Results]The incidence rate of brain tumor in Jiangsu Province from 2009 to 2019 showed an increasing trend(AAPC=4.12％,95％CI:3.31％～4.95％),and the increase in female(AAPC=5.79％,95％CI:4.44％～7.15％)was higher than that in male(AAPC=2.31％,95％CI:1.66％～2.97％);and the increase in urban areas(AAPC=4.84％,95％CI:3.52％～6.18％)was higher than that in rural areas(AAPC=3.04％,95％CI:2.12％～3.98％).The ASIRC also showed an increasing trend(AAPC=2.14％,95％CI:1.27％～3.02％).Birth cohort analysis showed that within the same age group,the incidence rate of brain tumors increased with increasing birth years.The average age of onset for crude incidence showed a delaying trend of 0.43 years old per year(t=7.09,P＜0.001);that for ASIRC was 0.20 years old per year(t=3.33,P=0.009).The proportion of patients in the age group of 60 years old and above increased from 35.79％in 2009 to 44.18％in 2019.[Conclusion]The incidence of brain tumor in cancer registration areas of Jiangsu Province showed an increasing trend from 2009 to 2019 with a delaying trend of average age of onset.

The NOD-like receptor protein 3 (NLRP3) inflammasome is essential in innate immune-mediated inflammation, with its overactivation implicated in various autoinflammatory, metabolic, and neurodegenerative diseases. Pharmacological inhibition of NLRP3 offers a promising treatment strategy for inflammatory conditions, although no medications targeting the NLRP3 inflammasome are currently available. This study demonstrates that clioquinol (CQ), a clinical drug with chelating properties, effectively 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.
