Objective: This study aims to explore the association between oral lichen planus (OLP) and Hashimoto’s thyroiditis (HT) and its anti-thyroid antibodies to provide clinical evidence for thyroid disease screening in patients with OLP. Methods: This study was approved by the institutional ethics committee. A total of 125 clinically and histopathologically confirmed patients with OLP were enrolled as the case group, and they were matched with 125 non-OLP controls based on sex and age. Demographic data (gender, age, lesion type, and disease duration) were collected from both groups. Serum levels of thyroid peroxidase antibodies (TPOAb) and thyroglobulin antibodies (TgAb) were measured to analyze their associations with sex, age, lesion type, and disease duration in patients with OLP. Result: The prevalence of HT in patients with OLP was 31.20%, significantly higher than that in the control group (9.60%) (χ2=18.504, P<0.001). The prevalence of HT in female patients with OLP (39.13%) was significantly higher than that in male patients (9.09%)（χ2=10.93，P<0.001）. The positivity rate of thyroid peroxidase antibodies (TPOAb) in patients with OLP (17.6%) was significantly higher than in the control group (4.0%) (χ2=10.989, P<0.001). The TPOAb positivity rate was significantly higher in female patients (22.83%) than in male patients (3.03%) (χ2=5.210, P=0.014). There was no statistically significant difference in the positivity rate of TgAb between patients with OLP (7.2%) and the control group (3.2%) (P>0.05). Patients with erosive lesions had a significantly higher TPOAb positivity rate (25.0%, 17/68) compared to those with non-erosive lesions (8.77%, 5/57), and the difference was statistically significant (χ2=4.831, P=0.028). Logistic regression analysis revealed that female patients with OLP had an 8.935-fold higher risk of being TPOAb positive compared to males (OR=8.935, 95%CI: 1.134-70.388, P=0.038). Patients with erosive OLP lesions had a 3.199-fold higher risk of TPOAb positivity compared to those with non-erosive lesions (OR=3.199, 95%CI: 1.064-9.618, P=0.038). Conclusion The prevalence of HT is higher in patients with OLP, with higher positivity rates of anti-thyroid antibodies observed in female patients and those with erosive OLP lesions. This suggests that thyroid disease screening should be incorporated into the clinical management of patients with OLP, especially for women and patients who present with erosive lesions.

AIM: To investigate the protective effect of β-sitosterol on retinal structure and function and its underlying molecular mechanism in a sodium iodate(NaIO3)-induced mouse model of dry age-related macular degeneration(ARMD).METHODS: A dry ARMD mouse model was established by NaIO3 injection. The therapeutic effect of β-sitosterol intervention was evaluated using fundus photography, histopathology(HE staining), and electroretinography(ERG). Network pharmacology was employed to screen potential targets of β-sitosterol in ARMD, and molecular docking was used to validate the binding ability between β-sitosterol and these targets. The impact of β-sitosterol on ARPE-19 cell viability and apoptosis pathways was analyzed using CCK-8 assay, Hoechst staining, and Western blotting.RESULTS: The β-sitosterol significantly alleviated structural damage in the retinas of model mice(increased retinal and outer nuclear layer thickness, reduced yellowish-white drusen-like deposits)and functional impairment(partial restoration of a-wave and b-wave amplitudes). Network pharmacology identified PON1 as a key target of β-sitosterol; molecular docking demonstrated that β-sitosterol binds to PON1 via hydrophobic interactions and hydrogen bonds. In vitro experiments showed that β-sitosterol(10 μmol/L)significantly increased ARPE-19 cell viability(P<0.01), reduced apoptosis(P<0.01), upregulated PON1 expression(P<0.01), and concurrently suppressed cleaved-Caspase3 expression(P<0.01).CONCLUSION: The β-sitosterol likely protects against oxidative stress-induced retinal damage by modulating PON1 to suppress the Caspase3-dependent apoptotic pathway. These findings provide experimental evidence supporting the development of β-sitosterol as a novel therapeutic agent for dry ARMD.

Objective To investigate the correlation between serum Irisin,long pentraxin 3(PTX3),human metas-tasis-associated lung adenocarcinoma transcript 1(MALAT1)levels and the severity of diabetic retinopathy(DR)and the value of combined diagnosis.Methods Eighty-five patients with type 2 diabetes mellitus(T2DM)combined with DR at Cangzhou Central Hospital from April 2022 to April 2023 were selected as the DR group,85 patients with T2DM alone were selected as the non-DR group,and 85 healthy volunteers were selected as the control group during the same period.Pa-tients in the DR group were further divided into the proliferative DR(PDR)group(38 patients)and the non-PDR group(47 patients)based on whether DR was in the proliferative phase.Clinical data of patients in the DR group were collected,including gender,diastolic pressure,age,systolic pressure,disease course,fasting plasma glucose(FPG),body mass in-dex,hemoglobin A1c(HbA1c),smoking history,triglyceride(TG),drinking history,peak systolic velocity(PSV),peak end-diastolic velocity(PEDV),resistance index(RI),fasting insulin(FINS),family history of diabetes,total cholesterol(TC),and homa-insulin resistance(HOMA-IR).Enzyme-linked immunosorbent assay was used to detect serum levels of Irisin and PTX3 in each group of patients,and real-time quantitative polymerase chain reaction was used to detect the ser-um level of MALAT1.The correlations between serum levels of Irisin,PTX3 and MALAT1 and the severity of DR were ana-lyzed using the Pearson correlation coefficient.The influencing factors of the DR severity were identified using the Logistic regression.The value of serum Irisin,PTX3,and MALAT1 levels in diagnosing DR alone was analyzed using the receiver operating characteristic(ROC)curve.The value of regimens containing and not containing serum Irisin,PTX3,and MAL-AT1 levels in diagnosing DR was analyzed using the ROC curve,net reclassification index(NRI),and integrated discrimina-tion improvement(IDI)index.Results The serum levels of Irisin,PTX3,and MALAT1 were compared among the three groups of patients,and the differences were statistically significant(all P＜0.001).The disease course of patients in the PDR group was longer than that in the non-PDR group,the PSV,PEDV and serum Irisin level were lower than those in the non-PDR group,while the RI,FPG,HbA1c,TG,FINS,HOMA-IR,and serum PTX3 and MALAT1 levels were higher than those in the non-PDR group(all P＜0.05).The serum Irisin level in DR patients was negatively correlated with the severity of DR(r=-0.512,P＜0.001),while the PTX3 and MALAT1 levels were positively correlated with the severity of DR(r=0.497,0.573,both P＜0.05).The Logistic regression analysis showed that the disease course,FPG,HbA1c,TG,FINS,HOMA-IR,PSV,PEDV,RI,and serum levels of Irisin,PTX3 and MALAT1 were influencing factors for the DR progression(allP＜0.05).The area under the curve(AUC)of serum Irisin,PTX3,and MALAT1 levels in diagnosing DR was 0.743,0.811,and 0.773,respectively.Compared with conventional diagnostic protocols,the AUC of the new diagnostic protocol containing serum levels of Irisin,PTX3,and MALAT1 significantly increased(Z=2.708,P=0.007),and the NRI and IDI were 0.039(95％CI:0.022-0.069)and 0.026(95％CI:0.014-0.047),respectively(all P＜0.05).Conclusion The serum Irisin level in DR patients decreases,while the serum PTX3 and MALAT1 levels increase,which are closely related to the severity of DR.Diagnostic plans containing serum Irisin,PTX3,and MALAT1 indicators have high diagnostic value.

Objectives:To observe the incidence of residual shunt post patent foramen ovale(PFO)closure and the effect of PFO closure in these migraine patients at one year after PFO. Methods:This retrospective study included patients who underwent PFO closure for migraine in the Second Affiliated Hospital Zhejiang University School of Medicine from January 2019 to June 2022,patients were divided into the grade 0 shunt group(n=67),the grade Ⅰ shunt group(n=10),the grade Ⅱ shunt group(n=13)and the grade Ⅲ shunt group(n=16)according to the results of contrast transthoracic echocardiography(cTTE)at 1 year after PFO closure.The incidence of postoperative migraine attacks among different groups of patients were compared.The risk factors of residual shunt after PFO closure were explored. Results:The mean age of enrolled 106 patients with migraine was(35.80±11.70)years,of which 83 patients(78.30%)were female.One year after PFO closure,the migraine attack and rating scale were significantly decreased compared to baseline in the grade 0 shunt group,in the grade Ⅰ shunt group and in the grade Ⅱ shunt group(all P<0.05),but not in the grade Ⅲ shunt group(P>0.05).The rate of significant and complete migraine was significantly higher in the grade 0 shunt group(58.21%),in the gradeⅠ shunt group(60.00%),in the grade Ⅱ shunt group(69.23%)as compared to the grade Ⅲ shunt group(18.75%,P=0.02)at one year after PFO.The rate of grade 0 shunt after PFO closure in patients with the microvesicles appearing in≥6 cardiac cycles in resting state before operation was significantly lower than in patients with the microvesicles appearing within 6 cardiac cycles and no microvesicles in resting state(24.00%vs.83.87%vs.70.00%,P=0.04).Logistic multivariate regression analysis showed that patients with microvesicles appearing beyond 6 cardiac cycles in resting state were more likely to have residual shunts in postoperative cTTE compared to the patients with negative cTTE and microvesicles appearing within 6 cardiac cycles in the cTTE in resting state before operation(OR=0.06,95%CI:0.02-0.23,P<0.01;OR=0.014,95%CI:0.05-0.41,P<0.01). Conclusions:Migraine patients who underwent PFO closure and with grade 0 to grade Ⅱ residual shunt at one year after PFO are most likely to have significant remission of migraine,while the incidence of migraine remission is low in patients with grade Ⅲresidual shunt.The incidence of residual shunt after PFO closure is higher in patients with the microvesicles appearing in 6 cardiac cycles in resting state in the cTTE before operation than in patients with the microvesicles appearing within 6 cardiac cycles and no microvesicles.

Objective To investigate the value of a nomogram model constructed from intratumoral and peritumoral magnetic resonance imaging radiomics combined with clinical characteristics in predicting the status of lymphovascular space invasion(LVSI)in cervical cancer.Methods A retrospective analysis was conducted on 178 cervical cancer patients confirmed by postoperative pathology,with 70 cases of LVSI(+)and 108 cases of LVSI(-).The patients were divided into a training set[142 cases,including 54 cases of LVSI(+)and 88 cases of LVSI(-)]and a test set[36 cases,including 16 cases of LVSI(+)and 20 cases of LVSI(-)]at a ratio of 8:2.All underwent magnetic resonance imaging before surgery,and regions of interest were manually delineated layer by layer on the T2WI sequence,with the peritumoral region being uniformly expanded outward.Univariate logistic analysis was performed on clinical factors to select independent factors for cervical cancer LVSI(+).Radiomic features were extracted separately from the intratumoral region,the peritumoral region,and the intratumoral-peritumoral region to construct radiomics models,and the differences between the peritumoral and the intratumoral-peritumoral models were compared.A combined model was established based on the radiomics scores of the optimal intratumoral-peritumoral model and clinical independent predictive factors,and a nomogram was plotted.Receiver operating characteristic curves were used to evaluate the diagnostic performance of each model,and decision curve analysis was used to assess the clinical value of the models.Results The combined model demonstrated the best performance among the various models,with AUC of 0.970 in the training set and 0.803 in the test set.Conclusion Intratumoral and peritumoral magnetic resonance imaging radiomics combined with clinical characteristics can effectively predict LVSI in cervical cancer.
