Postoperative cognitive dysfunction (POCD) is a clinically significant complication in elderly patients, largely driven by surgery-induced neuroinflammation. The cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway, a crucial regulator of innate immunity, has been implicated in neuroinflammatory activation. This study investigated whether electroacupuncture (EA) improves POCD by modulating this pathway in aged rats. Aged male Sprague-Dawley rats were subjected to sevoflurane anesthesia and splenectomy to establish a POCD model. Animals were divided into sham, POCD, POCD+EA, and POCD+EA+cGAS inhibitor groups. The EA groups received stimulation at Baihui (Governor Vessel 20 (GV20)), Neiguan (Pericardium 6 (PC6)), and Zusanli (Stomach 36 (ST36)) acupoints. Cognitive function was evaluated using the Morris water maze, while hippocampal expression of cGAS-STING pathway components and downstream effectors—interferon regulatory factor 3 (IRF3), nuclear factor kappa B (NF-κB), and interleukin-1 beta (IL-1β)—was assessed by Western blot. Cellular localization was determined by immunofluorescence staining. Compared with the Sham group, rats in the POCD group showed significant impairments in spatial memory, accompanied by upregulated protein expression of cGAS, STING, NF-κB, IRF3, and IL-1β in the hippocampus. Upon pathway activation, cGAS and STING proteins were predominantly co-localized with neurons, and their fluorescence intensity in the hippocampus was markedly increased. These behavioral deficits and molecular alterations were partially reversed in both the POCD+EA and POCD+EA+inhibitor groups. Electroacupuncture alleviates POCD in aged rats by inhibiting hippocampal cGAS-STING pathway activation and reducing neuroinflammation, suggesting a promising non-pharmacological strategy for POCD management.

AIM: To investigate factors associated with anterior chamber exudation following phacoemulsification combined with intraocular lens(IOL)implantation.

METHODS: Clinical data from patients with cataract who underwent phacoemulsification combined with IOL implantation at the hospital between June 2021 and June 2025 were retrospectively analyzed. Patients were divided into an exudation group and a non-exudation group according to the presence or absence of postoperative anterior chamber exudation. Demographic characteristics, underlying diseases, preoperative examination findings, surgery-related factors, intraoperative complications, and postoperative conditions were collected and compared between the two groups. Factors associated with anterior chamber exudation after phacoemulsification combined with IOL implantation were analyzed.

RESULTS: A total of 840 cataract patients(840 eyes)who underwent phacoemulsification combined with IOL implantation were enrolled. According to the presence or absence of postoperative anterior chamber exudation, 42 patients(42 eyes)were assigned to the exudation group, including 18 men and 24 women, with a mean age of 72.04±7.84 y; the remaining 798 patients(798 eyes)were assigned to the non-exudation group, including 370 men and 428 women, with a mean age of 65.13±9.25 y. Univariate analysis showed significant between-group differences in age, duration of cataract, diabetes mellitus, postoperative elevation of intraocular pressure, duration of corticosteroid eye-drop use, and lens nuclear grade(all P<0.05). Restricted cubic spline analysis demonstrated significant overall associations of age, duration of cataract, and duration of corticosteroid eye-drop use with the risk of postoperative anterior chamber exudation(all P<0.001). No significant non-linear associations were observed(P_{for non-linearity} >0.05), indicating linear relationships. Multivariable Logistic regression analysis showed that age(OR=1.096, 95%CI: 1.053-1.141), duration of cataract(OR=1.074, 95%CI: 1.042-1.107), diabetes mellitus(OR=2.630, 95%CI: 1.269-5.453), postoperative elevation of intraocular pressure(OR=4.311, 95%CI: 1.851-10.041), duration of corticosteroid eye-drop use(OR=2.082, 95%CI: 1.479-2.930), and lens nuclear grade ≥IV(OR=2.635, 95%CI: 1.309-5.304)were risk factors for postoperative anterior chamber exudation(all P<0.05). A nomogram prediction model was developed based on these factors. The calibration curve showed good agreement between the predicted and observed probabilities. ROC curve analysis showed that the AUC of the model for predicting postoperative anterior chamber exudation was 0.858(95%CI: 0.801-0.916), with a sensitivity of 0.810 and a specificity of 0.803.

CONCLUSION: Anterior chamber exudation following phacoemulsification combined with IOL implantation is influenced by multiple factors. Age, duration of cataract, diabetes mellitus, postoperative elevation of intraocular pressure, longer duration of corticosteroid eye-drop use, and greater lens nuclear hardness are risk factors. The nomogram developed using these factors demonstrates good predictive performance for postoperative anterior chamber exudation and may facilitate the early identification of high-risk patients and the development of individualized intervention strategies.

AIM: To evaluate whether Wnt pathway-related genes previously implicated in high myopia(HM)could serve as candidate genes for HM in the Chinese Han population, and to identify risk loci associated with HM susceptibility.METHODS: A case-control association analysis was conducted, involving 530 HM patients(HM group)and 1 087 healthy controls. The test efficacy was estimated using Quanto software. Peripheral blood DNA was extracted using the magnetic bead method, and seven candidate single nucleotide polymorphisms(SNPs)were genotyped using the Sequenom MassARRAY system, including HIVEP3 rs17365632, rs35134694, rs11210537, CTNNB1 rs13072632, CAMK2N1 rs10753502, TCF4 rs41396445 and Wnt7B rs73175083. Differences in allele and genotype frequencies between the HM and healthy control groups were compared under different inheritance models. Haplotype analysis was performed using SHEsis plus.RESULTS: All 7 SNPs had a genotyping detection rate exceeding 90%, and were in Hardy-Weinberg equilibrium(P>0.05). The test efficacy of the sample size was above 90.13%, indicating that the samples were representative of the population. In the HM group, the A allele frequency of HIVEP3 rs11210537 was significantly reduced(Pc=0.003, OR=0.889). Conversely, the G allele frequency was significantly elevated(Pc=0.003, OR=1.176). In an additive genetic model(AA vs GG), the AA genotype frequency was significantly lower than the GG genotype frequency(Pc=0.003, OR=0.583). Additionally, the frequency of the CCA haplotype of rs17365632, rs35134694, and rs11210537 in HIVEP3 was decreased in the HM group compared to the control group(Pc=0.008, OR=0.791).CONCLUSION: The SNP locus rs11210537 in the HIVEP3 gene is associated with genetic susceptibility to HM in the Chinese Han population, with the G allele identified as risk genetic markers. The CCA haplotype of rs17365632, rs35134694, and rs11210537 in the HIVEP3 gene represents a protection haplotype for HM.

Dental implantology has developed rapidly for over half a century,since pure titanium(99.7％)dental cylindrical threaded implants were exploited and osseointegration was introduced in 1960s by Prof.Br?nemark.The long term retention rates of 10 years or more are over 95％.However,the biological complications jeopardize the long term effects of dental implant treatment seriously.The prevalence of dental implant biological complications varies greatly among different reports resulting from the disparities on the defini-tions of dental implant biological complications.After analyzing and summarizing the major opinions proposed internationally in recent years,the consensus for the definition of dental implant biological complications has been reached.Generally the dental implant biologi-cal implications can be classified into early stage(before restoration)biological complications and late stage(after restoration)biological complications.The early stage biological complications include acute and chronic infections,pain,soft tissue deficiency,and osseointegration failure,etc.The late stage complications include peri-implant diseases(peri-implant mucositis and peri-implantitis),soft tissue deficiency around implant,implant loosening and dropping off,etc.The various risk factors related to different dental implant biological complications,the strategies of the prevention and treatment for the dental implant biological complications have been discussed comprehensively,and the consensus has been reached.It is aimed to advocate the dentist to pay more attention to the early prevention of the biological implant complications,to promote more researches on the implant biological complications,and to help elevate the level of dental implantology in our country.

Rheumatoid arthritis(RA)is a systemic inflammatory disease characterized by erosive arthritis that can eventually lead to joint deformity and loss of function,which is unknown.Autophagy is a self-degradation process in which cells reuse internal proteins and organelles allowing organisms to withstand adverse situations such as starvation and infection,and eventually allowing cells to survive.In recent years,many studies have discovered that autophagy plays a role in the pathogenesis of RA,including the production of pannus,synovitis,bone degradation,and other critical pathological connections that influence RA progression and prog-nosis.This article examines the function of autophagy in the pathogenesis of RA,with the goal of generating new ideas for future RA treatment and drug development.

Objective:Cognitive interviews were used to explore the target population's understanding and cognition of the Questionnaire about Gynaecological and Pelvic Pain Symptoms (ENDOPAIN-4D) in the Chinese context. The consistency of language expression and concept between the Chinese version ENDOPAIN-4D and the original scale was verified.Methods:Qualitative research methods were employed. Objective sampling method was used to select the patients with endometriosis/adenomyosis in the gynecological ward of Chinese Academy of Medical Sciences & Peking Union Medical College Hospital from October to December 2023 as the interview subjects. Two rounds of cognitive interviews were conducted, and the interview data were coded and analyzed using the Question Appraisal System. Based on the interview results and the recommendations of the expert group, the scale items were revised to form the Chinese version of ENDOPAIN-4D, and reliability and validity tests were conducted.Results:This study ultimately included 24 patients with endometriosis/adenomyosis, aged 24-47 years. The results of the first round of interviews showed that some interviewees had ambiguous understandings of the 16 items in the questionnaire, most of the item questions were concentrated in the category of "3 clarity, 4 hypotheses", and a small number of questions appeared in the category of "2 guidance, 5 knowledge/memory, 7 options", and were revised. The results of the second round of interviews showed that respondents could correctly understand the scale items. The Cronbach α coefficient of the total scale was 0.874, and the retest reliability was 0.952. The correlation coefficient of the Chinese version of the Global Pain Scale as the reference index of compatibility validity was 0.764 ( P<0.01), and the exploratory factor analysis extracted a total of 4 dimensions, with a cumulative variance contribution rate of 61.169%. The final formal questionnaire included 21 items in 4 dimensions including spontaneous pelvic pain, pain during sexual intercourse, intestinal pain and/or symptoms, and other symptoms. Conclusions:Cognitive interviews were used to identify cognitive biases in the target population during the completion of the scale and to address them appropriately, reducing the differences in the target population's understanding of the ENDOPAIN-4D scale and improving its scientific validity and reliability.

Objective To analyze the association between eye-related behaviors and myopia among preschool chil-dren in Ningxia Hui Autonomous Region,and to develop a predictive nomogram model.Methods Using stratified cluster random sampling,36 062 preschool children from 400 randomly selected kindergartens in Ningxia Hui Autonomous Region were enrolled between October and December 2023.Primary caregivers of participants completed structured question-naires.Data were randomly split into a training set(n=25 243,70％)and a validation set(n=10 819,30％)in a ratio of 7∶3.The training set was used for model construction,and the validation set for external validation.Calibration plots and the Hosmer-Lemeshow(H-L)goodness-of-fit test assessed agreement between predicted and observed risks.Decision curve analysis(DCA)and clinical impact curve analysis(CICA)evaluated clinical utility.Results The myopia preva-lence among preschool children in Ningxia Hui Autonomous Region was 3.8％.A nomogram model based on binary Logistic regression showed area under the curve(AUC)values of 0.88(95％CI:0.87-0.89)for the training set and 0.89(95％CI:0.87-0.90)for the validation set,indicating strong discriminative ability.Calibration curves and H-L tests revealed good model fit(training set:x2=4.92,P=0.766;validation set:x2=5.52,P=0.961),with all P＞0.05.DCA and CICA confirmed clinical utility.The nomogram identified parental myopia,academic pressure,frequency of eye fatigue,daily screen time,and regular vision checks as the top five predictors of myopia.Conclusion The nomogram demonstrates promising potential for predicting myopia risk in preschool children in Ningxia Hui Autonomous Region,serving as a robust tool for clinical and educational myopia risk assessment.

Objective:To identify tumor-infiltrating immune cells that affect the prognosis of endometrial cancer(EC)with no specific molecular profile(NSMP)subtypeand to establish an integrated prognostic model based on immune cells.Methods:Gene expression data,whole exome sequencing data,and corresponding clinical infor-mation for EC patients were obtained from the The Cancer Genome Atlas(TCGA)database.The CIBERSORTx algorithm was used to evaluate the infiltration levels of 22 types of immune cells in the tumor microenvironment.Kaplan-Meier survival analysis,along with univariate and multivariate Cox regression analyses were used to identi-fy immune cells with prognostic values.A prognostic nomogram was subsequently developed based on significant immune cells and clinicopathological parameters.Results:A total of 169 EC patients classified as NSMP subtype-swere included in this study.Among them 123 patients(72.8％)were aged＜70 years,and 152 patients(89.9％)had type Ⅰ tumors.Kaplan-Meier curves showed that the proportion of plasma cells(P＜0.001),M1 macrophages(P=0.038)and activated NK cells(P=0.01)were significantly associated with overall survival.Multivariate Cox regression analysis revealed that the proportion of activated NK cells(proportion ≥0.027:HR 0.23,95％CI 0.08-0.66,P=0.006),age(≥70 years:HR4.59,95％CI 1.80-11.70,P=0.001)and tumor stage(stage Ⅱ:HR3.87,95％CI 1.18-12.70,P=0.026;stage Ⅲ:HR 6.08,95％CI 1.69-21.87,P=0.006;Ⅳ stage:HR 10.81,95％CI 3.07-38.08,P＜0.001)are independent prognostic indicators for NSMP tumors.A nomogram model was estab-lished by combining activation of NK cells,tumor stage and patient age.Internal cross-validation showed that the integrated prognostic model exhibited good predictive ability for the overall survival rates of patients(P＜0.001).Conclusions:Elevated tumor-infiltrating activated NK cells serve as an independent prognostic indicator for NSMP-subtype EC patients.When integrated with tumor stage and age,they form a robust multivariable prognos-tic model with superior predictive power.

Purpose To investigate the diagnostic value of immunohistochemical(IHC)and molecular markers in diffuse pleural mesothelioma(DPM).Methods A total of 114 cases of DPM were retrospectively analyzed for clinical and imaging manifestations,histologic subtype and tumor grade.The positivity rates of Calretinin,WT-1,CK5/6,MC,D2-40,UPK3B,and GATA3 were assessed by IHC,and the loss rates of BAP-1 and MTAP were determined.The concordance between MTAP IHC and p16 gene fluorescence in situ hybridization(FISH)status was calculated,a-long with the sensitivity and specificity of MTAP IHC relative to p16 FISH.Results Among the 114 DPM patients,66(57.9％)were male and 48(42.1％)were female,with a mean age of 58.1 years(range 16-85 years).Imaging predominantly demonstrated pleural effusion and multiple pleural nodules(55.3％,63/114).Histologically,epitheli-oid,sarcomatoid and biphasic subtypes accounted for 88(77.2％),17(14.9％)and 9(7.9％)cases,respectively.Within the epithelioid group,low and high-grade tumors numbered 69(78.4％)and 19(21.6％),respectively.In epithelioid DPM,the highest IHC positivity rates were observed for Calretinin(92.4％,81/88),D2-40(90.0％,79/88)and WT-1(90.0％,79/88).In sarcomatoid DPM,D2-40(76.5％,13/17),WT-1(64.7％,11/17),and Cal-retinin(29.4％,5/17)showed the greatest positivity.UPK3B was positive in epithelioid(59.1％,39/66)and bi-phasic cases(66.7％,4/6),but was absent in sarcomatoid tumors(0/12).Among all DPM cases,loss rates were 47.3％(53/112)for BAP-1 and 19.2％(20/104)for MTAP by IHC,p16 gene deletion by FISH was 31.5％(34/108);Concordance between MTAP IHC and p16 FISH was 81.0％(81/100);MTAP IHC had a specificity of 95.5％(64/67)and sensitivity of 51.5％(17/33)relative to p16 FISH.Additionally,GATA3 was highly expressed in sarco-matoid DPM(76.5％,13/17).UPK3B positivity differed significantly between thoracoscopic DPM(59.2％,32/54)and percutaneous biopsy samples(36.7％,11/30)in epithelioid DPM(P＜0.05).WT-1 positivity was higher in thoracoscopic than percutaneous samples of sarcomatoid DPM(90.0％ vs 28.6％,P=0.009).Conclusion Calreti-nin,D2-40,and WT-1 are highly sensitive mesothelial markers and should serve as first-line IHC stains in DPM diag-nosis.UPK3B is diagnostically valuable in epithelioid DPM,GATA3 may complement the diagnosis of sarcomatoid DPM,and MTAP IHC can be used as a surrogate or adjunct to p16 FISH.
