Objective: To assess the effect of 12-year-old children s pit and fissure sealants on the health of first permanent molars, so as to provide evidence for optimizing caries prevention strategies among children. Methods: In March 2025, a cluster random sampling method was used to conduct oral examinations on 965 students aged 12 from Chengdu s 2021 Comprehensive Intervention Program for Pediatric Oral Diseases. Data from the Comprehensive Intervention System for Children s Oral Diseases were referenced. Participants were divided into a sealed group ( n =755) and an unsealed group ( n =210) based on whether they had received sealants on their first permanent molars. Chi square test or analysis of variance were used to compare indicators such as caries incidence, new caries detection rate, and new caries mean (DMFT increment) between the two groups Results: The sealed group showed significantly lower caries incidence, new caries detection rate, and new caries mean (33.38%, 17.65%, 0.59±1.00) compared to the unsealed group (43.81%, 24.70%, 0.87±1.22)( χ 2/F =7.79, 18.26, 9.55, all P <0.05). However, no significant difference was found in the filled teeth ratio between the two groups (20.38% , 20.16%; χ 2=0.01, P =0.94). In girls, the sealed group exhibited significantly lower caries incidence, new caries detection rate, and new caries mean (36.78%, 20.99%, 0.69± 1.10 ) than the unsealed group (57.55%, 33.52%, 1.15±1.29) ( χ 2/F =14.42, 23.76, 10.92, all P <0.05), whereas no significant differences were observed between boys in the sealed (30.47%, 14.85%, 0.50±0.89) and unsealed groups (29.81%, 16.18%, 0.59± 1.08) ( χ 2/F =0.02, 0.41, 0.74, all P >0.05). Boys had significantly lower new caries detection rates and new caries means than girls in both groups ( χ 2/F =16.20, 6.94; 29.93, 11.84, all P <0.05). In urban areas, the sealed group had lower new caries detection rates and new caries means (19.37%, 0.68±1.04) than the unsealed group (24.66%, 0.90±1.20) ( χ 2/F =6.86, 3.94, both P <0.05). In suburban areas, all indicators for the sealed group (24.71%, 13.77%, 0.42±0.87) were significantly lower than those for the unsealed group (38.81%, 24.77%, 0.82±1.28) ( χ 2/F =5.28, 15.36, 6.00, all P <0.05). Indicators from specialized dental institutions (11.25%, 4.81%, 0.16±0.56) were significantly lower than those from county level or above general hospitals (33.33%, 19.11%, 0.38±1.00) and primary healthcare institutions (37.59%, 19.24%, 0.67±1.05) ( χ 2/F =20.99, 34.31, 21.08 , all P <0.01). Conclusions The 12-year-old children s pit and fissure sealants effectively reduce the caries incidence in first permanent molars, particularly showing significant effectiveness in girls and suburban children. Intervention strategies should be optimized according to gender.

Objective To characterize Schistosoma japonicum Class F G protein-coupled receptors (GPCRs), and to decipher the biological function of S. japonicum Smoothened receptor (SjSMO), so as to provide insights into screening of novel anti-schistosomal drug targets. Methods Six Class F GPCRs were identified from the S. japonicum GPCR library using a hidden Markov model (HMM) and genome annotation filese, including five frizzled (FZD) receptors (SjFZD4, SjFZD5, SjFZD7, SjFZD8, SjFZD10) and one Smoothened receptor (SjSMO). Protein domain analysis was performed at the SMART website, and a phylogenetic tree was built with the software MEGA 11.0 and refined with the Interactive Tree Of Life (iTOL) tool. The expression profile and tissue localization of S. japonicum class F GPCRs were analyzed using the real-time fluorescence-based quantitative PCR (RT-qPCR) assay and in situ hybridization, and the effects of SjSMO on parasite growth, development, reproduction, and oviposition were examined using in vivo and in vitro RNA interference (RNAi). S. japonicum adult worms were selected for double-stranded RNAi (dsRNA) in in vitro experiments, and a green fluorescent protein (GFP) negative control group and SjFZD4, SjFZD5, SjFZD7, SjFZD8, SjFZD10, and SjSMO dsRNAi groups were assigned to observe the parasite vitality and state and calculate the female and male rating rate. For in-vivo animal experiments, 6-week-old SPF female mice of the Kunming strain were randomly divided into a GFP dsRNA negative control group and SjFZD4, SjFZD5, SjFZD7, SjFZD8, SjFZD10, and SjSMO dsRNAi groups. Worms and liver tissues were collected for measurement of the worm length and estimation of the worm burdens, and changes in the parasite reproductive organs were observed using alum carmine staining. In addition, the number of S. japonicum eggs in mouse livers was counted and the pathological damages of mouse livers were recorded. Results The five FZD receptors and one Smoothened receptor all contained a conserved Frizzled domain. Phylogenetic analysis revealed that SjSMO formed an independent evolutionary clade, which exhibited a far genetic distance from the FZD family. RT-qPCR assay quantified stable SjSMO expression in male worms but gradually decreased in female worms with worm development, and in situ hybridization revealed high systemic expression of SjSMO. In vitro RNAi results revealed a significant difference in pairing rates among all groups (χ² = 130.530, P < 0.000 1). Only the SjSMO interference group exhibited a markedly reduced worm pairing rate of 20.00%, which was significantly lower than that of the control group (94.74%) (P < 0.000 1), accompanied by decreased worm vitality. In contrast, no statistically significant differences in pairing rates were observed between each FZD family gene interference group and the control group (all P > 0.05). In vivo RNAi assay revealed that SjSMO dsRNAi 1 to 26 days post-infection resulted in a significant reduction in worm length, with reductions in the male worm length by 32.27% and female worm length by 36.77% as compared to controls [male worms: (6.51 ± 1.77) mm vs. (9.62 ± 1.44) mm, t = 7.196, P < 0.000 1; female worms: (5.49 ± 1.36) mm vs. (8.68 ± 2.60) mm, t = 5.953, P < 0.000 1], as well as arrest of testicular development in male worms and ovarian development in females. In addition, SjSMO dsRNAi 26 to 42 days post-infection was found to significantly reduce hepatic egg burdens in mice, with a 49.10% reduction in the count of liver eggs in the SjSMO dsRNAi group relative to the GFP dsRNA negative control group [(2 824 ± 844) eggs per gram vs. (5 548 ± 797) eggs per gram; t = 4.064, P < 0.05], and to alleviate granuloma formation and severity of hepatic fibrosis. Conclusion SjSMO is a key receptor that regulates the growth, development, reproduction, and oviposition of S. japonicum, which provides a new potential target for development of anti-schistosomal drugs.

ObjectiveTo observe the mechanism through which Qige San inhibits tumor angiogenesis in esophageal cancer （EC） by regulating the microRNA-133a （miR-133a）/phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway. MethodsCell experiments were conducted by transfecting miR-133a mimics through liposomes and utilizing PI3K/Akt signaling pathway inhibitors. The effects of 60 mg·L^-1 and 100 mg·L^-1 Qige San on inflammatory factor secretion in the supernatant of EC9706 cells （esophageal cancer cells） were observed. EC9706 cell supernatants were then extracted and used as conditioned media to treat human umbilical vein endothelial cells （HUVECs）. The effects of the conditioned media on the proliferation， migration， tube formation， and apoptosis of HUVECs were examined. Animal experiments involved establishing a subcutaneous tumor model in nude mice with EC9706 cells. After grouping and administration， tumor volumes were measured regularly. At the end of the experiment， tumors were harvested， and histopathological changes were observed under a microscope after hematoxylin-eosin （HE） staining. Real-time polymerase chain reaction （Real-time PCR） was adopted to measure miR-133a expression in the tumor tissue of each group， while Western blotting was employed to analyze the expression of key signaling molecules， such as phosphorylated Akt （p-Akt）， as well as endothelial cell markers， cluster of differentiation 31 （CD31） and cluster of differentiation 34 （CD34）， in the tumor tissue. ResultsCell experiments showed that compared with the blank group， the supernatant of EC9706 cells promoted tube formation of HUVECs （P<0.05）. Both low and high doses of Qige San inhibited tube formation of HUVECs （P<0.05）. All doses of Qige San， PI3K/Akt inhibitor， and the combination reduced the content of interleukin-6 （IL-6） （P<0.05）， while high-dose Qige San， inhibitor， and combination all reduced the content of interleukin-8 （IL-8） （P<0.05）. Compared with the EC9706 blank supernatant group， Qige San-conditioned medium inhibited the proliferation of HUVECs （P<0.05）. Qige San， the inhibitor， and the combination all inhibited the migration and tube formation （P<0.05） and increased the late apoptosis and total apoptosis rates of HUVECs （P<0.05）. In addition， the low-dose combination induced early apoptosis of EC9706 cells （P<0.05）. Compared with the blank supernatant group， the miR-133a mimic combined with Qige San synergistically reduced IL-6/IL-8 （P<0.05）， and enhanced the inhibition on proliferation， migration， and tube formation of HUVECs （P<0.05）. Animal experimental results showed that compared with the model group， both Qige San and cisplatin inhibited the growth of xenograft tumors in nude mice （P<0.05）， promoted tumor cell necrosis， and reduced capillary formation. High-dose Qige San upregulated miR-133a expression （P<0.05）. Moreover， compared with the model group， cisplatin， Qige San， and the combination all downregulated the expression of p-Akt， CD31， and CD34 （P<0.05）. ConclusionQige San upregulates miR-133a expression， inhibit PI3K/Akt signaling pathway activity， and improve the tumor inflammatory microenvironment to suppress the growth and tumor angiogenesis of HUVECs， thereby inhibiting esophageal cancer.

Objective:To explore the medication law for threatened irritability in ancient gynecological monographs based on data mining.Methods:Based on Zhong Hua Yi Dian (5th edition), Chinese Medicine Resource Network and the paper version of ancient books, the representative gynecological monographs from the pre-Qin to the Qing Dynasty were selected to retrieve the prescriptions for the treatment of fetal irritability and establish a database. Excel 2019, IBM SPSS Modeler 18.0 and IBM SPSS Statistics 26.0 software were used to perform frequency statistics, association rule analysis and clustering analysis on the data of Chinese materia medica, analyze the core drug groups, and explore the medication laws. Results:A total of 151 prescriptions were included, including 7 kinds of TCM syndrome types, involving 111 kinds of Chinese materia medica. The most commonly used Chinese materia medica were Angelicae Sinensis Radix, Glycyrrhizae Radix et Rhizoma, Atractylodis Macrocephalae Rhizoma, Chuanxiong Rhizoma, and Paeoniae Radix Alba, etc. The efficacy categories were mainly tonic, heat-clearing, blood-activating and stasis-resolving; the medicinal properties were mainly warm and neutral; the tastes were mainly sweet and pungent; the main meridians were spleen, lung, liver and kidney meridians. 17 commonly used TCM combinations were obtained by association rule analysis, and five core TCM combinations were obtained by clustering analysis.Conclusions:In the treatment of threatened irritability, ancient doctors used the method of tonifying kidney and invigorating spleen, tonifying qi and nourishing blood, clearing heat and preventing miscarriage flexibly. The core drugs were mainly Angelicae Sinensis Radix, which was mostly modified on the basic prescriptions such as Siwu Decoction and Jiaoai Decoction.

Objective:To investigate predictive value of dynamic electrocardiogram heart rate variability(HRV)combined with three-dimensional spot tracking echocardiography(3D-STE)for postoperatively major adverse cardiovascular events(MACE)in patients with coronary heart disease(CHD).Methods:The clinical data of 80 CHD patients,who underwent percutaneous coronary intervention(PCI)treatment at Beijing Rehabilitation Hospital affiliated with Capital Medical University from January 2022 to December 2023,were retrospectively collected.All patients underwent dynamic electrocardiogram HRV and 3D-STE examination before surgery,and 1-year follow-up.The condition of occurring MACE during the follow-up period was analyzed as statistical method,and the patients were divided into occurrence group(21 cases)and non-occurrence group(59 cases).The relevant parameters of dynamic electrocardiogram HRV and 3D-STE examination of occurring MACE of CHD patients between two groups were compared,and the predictive value of dynamic electrocardiogram HRV combined with 3D-STE examination for postoperative MACE of CHD patients was analyzed.Results:In 80 CHD patients,21 cases occurred postoperative MACE,with an incidence rate of 26.25%.The standard deviation of the average NN intervals(SDANN)(65.26±9.65)ms of 5-minute sinus,the standard deviation of normal-to-normal intervals index(SDNN Index)(40.15±6.36)ms of 5-minute in continuous 24 hours,the root mean square of successive differences(r-MSSD)(36.86±4.55)ms between the normal adjacent cardiac cycles,the left atrial emptying fraction(LAEF)(40.25±4.53)%,and the left atrial storage phase strain(LASr)(15.24±3.62)%in CHD patients with MACE were lower than those without MACE[(87.45±10.22)ms,(52.45±7.85)ms,(46.54±6.25)ms,(48.54±6.33)ms,(19.99±4.55)%],and the left atrial pre-contraction volume(LAVp)(42.51±3.65)ml was higher than that(35.18±2.99)mL in patients without MACE,with statistically significant differences(t=8.666,6.457,6.499,9.093,5.510,4.317,P<0.05).Logistic regression analysis showed that SDANN,SDNN Index,r-MSSD,LAVp,LAEF,LASr were correlations with the occurrence of postoperative MACE in CHD patients(OR=0.756,0.772,0.694,2.481,0.721,0.739,P<0.05).The receiver operating characteristics(ROC)curves indicated that the area under curve(AUC)values of SDANN,SDNN Index,r-MSSD,LAVp,LAEF and LASr were all greater than 0.70 in predicting postoperative MACE in CHD patients,which indicated all of them had predictive value,and the predictive value of the combined detection was higher.Conclusion:Dynamic electrocardiogram HRV and 3D-STE parameters have a certain predictive value for the occurrence of postoperative MACE in CHD patients,and the predictive value of the combined detection for the them are higher.Therefore,dynamic electrocardiogram HRV and 3D-STE parameters can be used as one of the important reference schemes of assessing postoperative MACE of patients.

Objective:To investigate the clinicopathological characteristics, molecular features, differential diagnosis and prognosis of renal cell carcinoma (RCC) with TFEB gene amplification.Methods:A total of 113 cases of unclassified RCCs and RCCs with TFEB positive expression were collected from the Affiliated Hospital of Qingdao University and Navy 971 Hospital from January 2010 to December 2024. Eight cases of RCCs with TFEB amplification were identified using tissue microarrays, immunohistochemistry, and fluorescence in situ hybridization (FISH) techniques. The clinicopathological data and prognosis of the 8 cases were summarized, and relevant literature was reviewed.Results:Among the 8 cases, there were 5 males and 3 females. The average age was 63.4 (54, 77) year and the median age was 63.5 (59.0, 65.5) year. Seven cases were detected through physical examination, and 1 case presented with initial symptoms of metastasis to bones and lungs. The cohort included 1 biopsy specimen and 7 surgical resection specimens. The tumor diameters ranged from 2.5 to 15.0 cm. The cut surfaces of 5 cases were grayish-yellow or grayish-red, and 2 cases exhibited a colorful appearance, among which 3 cases involved renal sinus and 1 case showed invasion of the perirenal fat tissue. Microscopically, 4 cases were composed of clear cells arranged in solid sheets or acinar structures, along with varying numbers of eosinophilic cells. Two cases exhibited the morphology of high-grade eosinophilic RCC, and 1 case presented biphasic morphology with diffuse polygonal eosinophilic tumor cells and dense small cell components. The remaining 1 case exhibited the morphology of clear cell RCC. According to the WHO/ISUP nuclear grading system, 6 cases were Grade 3 and 2 cases were Grade 2. Multifocal necrosis was observed in 4 cases. In 4 surgical specimens, the tumor tissue invaded the renal parenchyma, with 2 cases showing nodular infiltration to surrounding tissues and 1 case with intravascular tumor thrombus. Immunohistochemical results showed varying degrees of TFEB nuclear positivity in 6 cases (6/8). Melanocytic markers such as Melan A (5/8) and HMB45 (3/8) were expressed at varying degrees. Cathepsin K (6/8), GPNMB (6/8), P504s (7/8) and CD10 (7/8) were positively expressed in most cases. FISH results revealed high-copy amplification of TFEB gene in 4 cases (partially showing clustered amplification) and low-copy amplification in 4 cases. During the follow-up period of 3 to 64 months of the 8 cases, 3 cases metastasized and 2 cases died of disease (both with high-copy TFEB gene amplification).Conclusions:RCC with TFEB gene amplification is rare and exhibits diverse morphological features. A common morphological characteristic of this type of tumor is a mixture of sheet-like clear cells and high nuclear grade eosinophilic cells. Combined immunohistochemical staining for TFEB, melanocytic markers, and GPNMB is helpful for the diagnosis of the tumor, and FISH detection of TFEB gene amplification is the most definitive method in diagnosing this tumor. RCC with TFEB gene amplification usually presents with strong aggressiveness and poor prognosis. Combining surgical resection with immunotherapy or VEGFR-targeted drugs might have therapeutic effects on the tumor.

Objective:To analyze the distribution of allergen components of dust mite in children with airway allergic diseases.Methods:This was a cross-sectional study. The clinical data of children with dust mite-induced allergic asthma (AA) complicated with allergic rhinitis (AR) or allergic rhinitis who were treated in Department of Allergy,Beijing Children′s Hospital from January 2019 to October 2022 were retrospectively analyzed. The spedific IgE (sIgE) levels to Der p1,Der p2,Der p5,Der p7,Der p10,Der p21,Der p23 and Der f1,Der f2 were detected by protein chip method. The distribution of dust mite sensitized components and the sIgE levels in children with different airway allergic diseases and different ages were compared.Results:Among 138 children with airway allergic diseases,there were 97 boys and 41 girls,age (6.86±2.61) years old,and there were 106 cases of AA combined AR (AAAR group) and 32 cases of AR alone (AR group). The sensitization rates of Der p2 was the highest (75.4%,104/138),followed by Der f2 (74.6%,103/138),Der f1 (73.9%,102/138),Der p1 (71.7%,99/138),Der p21 (19.6%,27/138),Der p5 (16.7%,23/138),Der p23 (14.5%,20/138),Der p7 (11.6%,16/138) and Der p10 (2.9%,4/138). The co-sensitization rate of Der p1,Der p2,Der f1 and Der f2 was the highest (31.2%,43/138). There was no significant difference in sensitization rate of dust mites components between AAAR group and AR group(all P>0.05). AAAR group had higher levels of sIgE to Der p23 than AR group [0.1 (0,0.1) IU/ml vs. 0 (0,0.1) IU/ml,Z=-2.819, P=0.005]. There were no significant differences in the positive rate of dust mite components and sIgE levels between children aged≤6 and>6 years old with airway allergic diseases(all P>0.05). Conclusions:Der p1,Der p2,Der f1 and Der f2 are the major components of dust mites sensitizing airway allergic diseases in children. Der p1,Der p2,Der f1 and Der f2 are the main co-sensitizing components in children with dust mite-induced airway allergic diseases. Compared with AR,the sIgE level to Der p23 in children with AAAR is higher.

Objective:To investigate the effect of intradialytic cerebral blood flow (CBF) fluctuation on cognitive decline in middle-aged and elderly maintenance hemodialysis (MHD) patients.Methods:It was a prospective cohort study. MHD patients aged ≥50 years from Beijing Shijitan Hospital were enrolled from January 2023 to June 2023. Middle cerebral artery mean flow velocity (MFV) was serially monitored via transcranial Doppler (TCD) during dialysis sessions. Cognitive function was assessed at baseline and after 12-month follow-up using standardized neuropsychological tests: montreal cognitive assessment (MoCA), auditory verbal learning test (AVLT 5), complex figure test (CFT), trail making test-B (TMT-B), Stroop color and word test (SCWT), and symbol digit modalities test (SDMT). ΔMFV was calculated as pre-to-post dialysis MFV difference. Multivariable linear regression was used to analyze the association of ΔMFV and cognition.Results:A total of 121 MHD patients were recruited with an age of (63.63±8.44) years. There were 97 males (80.2%), and the dialysis vintage was (55.08±54.73) months. Significant intradialytic MFV reductions were observed ( P<0.05). At 12 months, cognitive decline manifested in global cognition (MoCA), memory (CFT-memory), executive function (TMT-B, SCWT-C, SCWT-T), attention (SDMT), visuospatial ability (CFT-copy)(all P<0.05). Multivariable linear regression analysis revealed ΔMFV independently predicted declines in: MoCA ( B=0.066, 95% CI 0.018-0.113, P=0.007), AVLT5 ( B=0.050, 95% CI 0.004-0.097, P=0.035), TMT-B ( B=-1.955, 95% CI -3.453--0.457, P=0.011), SCWT-C ( B=0.298, 95% CI 0.112-0.484, P=0.002), SCWT-T ( B=-1.371, 95% CI -2.303--0.439, P=0.004). Conclusions:Hemodialysis induces acute CBF reductions detectable by TCD. Cumulative intradialytic CBF fluctuations may accelerate cognitive deterioration in middle-aged and elderly MHD populations, particularly affecting memory and executive domains.

Objective:To analyze the epidemiological and clinical features of infectious diseases of the central nervous system (CNS).Methods:A cross-sectional study and analysis were conducted to summarize the epidemiological and clinical characteristics of 9 918 patients with CNS infectious diseases, who were diagnosed and treated at 29 hospitals across China from January 1, 2001 to December 31, 2020. Data collected included demographic data, clinical manifestations, health economic indicators, and prognostic outcomes.Results:Among the 9 918 collected cases of CNS infectious diseases, 5 559 were male (56.0%) and 4 359 were female (44.0%), with an onset age of 38 (25, 53) years. Education level: slightly more junior high school education (2 651 cases, 26.7%), and less elementary school education and below (2 181 cases, 22.0%) were found. Occupational distribution: farmers were found predominant (3 215 cases, 32.4%), followed by workers (1 826 cases, 18.4%) and students (1 633 cases, 16.5%). Clinical manifestations: headache (6 074 cases, 61.2%), fever (5 869 cases, 59.2%) and positive meningeal irritation signs (2 273 cases, 22.9%) were the 3 most common clinical manifestations, followed by nausea and (or) vomiting (2 095 cases, 21.1%), impaired consciousness (2 077 cases, 20.9%), psychiatric symptom (1 866 cases, 18.8%) and epilepsy (1 627 cases, 16.4%), etc., and cranial nerve involvement was found in 669 cases (6.7%). Major pathogens included viruses in 6 814 cases (68.7%), Mycobacterium tuberculosis in 1 677 cases (16.9%), common bacteria in 864 cases (8.7%), fungi in 254 cases (2.6%), spirochetes of syphilis in 183 cases (1.8%), parasites in 121 cases (1.2%), and rickettsiae in 5 cases (0.1%). Urban-rural distribution: slightly more cases were found in the countryside (5 418 cases, 54.6%) than in the towns (4 500 cases, 45.4%). Distribution of onset by season: 2 412 cases (24.3%) fell ill in spring, 2 835 cases (28.6%) in summer, 2 187 cases (22.1%) in fall, and 2 484 cases (25.0%) in winter. Health economics: the duration of hospitalization was 15 (8, 27) days, and the cost of hospitalization was 1.53 (0.91, 3.02)×10 000 yuan. Prognosis: 9 531 cases (96.1%) were cured or improved, and 92 cases (0.9%) died. Conclusions:The pathogens responsible for CNS infectious diseases are predominantly viruses. Although the incidence is slightly higher during the summer months, the overall seasonal pattern is not particularly pronounced. These infections are more commonly observed in young and middle-aged males and present with a diverse range of clinical manifestations, contributing to a significant disease burden.

Objective To evaluate answers to typical clinical questions related to neuro-ophthalmology generated by Artificial Intelligence(AI)Large Language Models(LLM)and to explore the performance of neuro-ophthalmology-related questions on LLM in a multidimensional manner using objective and expert assessment.Methods Multicenter,random-ized,cross-sectional pilot study.Thirty typical questions related to neuro-ophthalmology were selected based on four per-spectives:definition,etiology,clinical manifestations and signs,and treatment and prognosis,and were analyzed quantita-tively using Deepseek,Wenxin Yiyin 4.0,Doubao,and Kimi 1.5,which are four open-source LLMs in China,and quantita-tively analyzed with objective assessment;and quantitatively rated by three ophthalmologists using expert assessment for 120 answer texts.Three ophthalmology experts quantitatively scored the 120 answer texts.Three ophthalmologists quantita-tively scored the 120 answer texts.Level 3,5,and 4 Likert scales were developed according to the completeness,accura-cy,professionalism,relevance,and criticality of the question texts,respectively.The best-performing LLM was selected,and its performance was observed across the four types of questions.Additionally,three other experts assessed whether the best-performing one could be evaluated as a substitute for real-world doctor-patient communication.Results In the objective Chinese text reading difficulty analysis,the differences in total word count among the four LLMs were statistically significant(all P＜0.001).Of the four LLMs,Kimi 1.5 performed the best,with frequencies of 61％,29％,and 41％for the highest scores in completeness(3),accuracy and professionalism(5),and relevance and usefulness(4),respective-ly.Kimi 1.5 performed more consistently on the questions on the four areas of neuro-ophthalmologic disorders:definition,etiology,clinical manifestations and signs,treatment,and prognosis,with no between-group differences(P＞0.05).Con-clusion Chinese language LLMs have great potential in the clinical application of neuro-ophthalmology.Kimi 1.5 outper-forms other LLMs in terms of completeness,accuracy,professionalism,relevance,and usefulness,but it still cannot re-place real-world doctor-patient communication.There is a need to explore new diagnostic and therapeutic model of AI+physician in the future.
