This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.

Objective To investigate the nutritional quality characteristics of vitamin D3-fortified yogurt and explore its improving effect on vitamin D metabolism in the body under simulated weightlessness,thereby providing a theoretical basis for the development of functional foods.Methods Using reconstituted milk as the matrix and Vitamin D3(VD3)microcapsule powder as the fortifier,VD3-fortified yogurt was prepared.A systematic study was conducted to investigate the effects of different gradients(1.25 μg/100 mL,2.50 μg/100 mL,3.75 μg/100 mL,5.00 μg/100 mL,6.25 μg/100 mL)of VD3 microcapsule addition on its quality characteristics(titratable acidity,solid content,water-holding capacity,syneresis).In vivo assessments were conducted using a Sprague-Dawley(SD)rat tail-suspension model to simulate weightlessness.Levels in serum 25(OH)D3,1,25-(OH)2D3,calcium(Ca),and phosphorus(P)were detected using the enzyme-linked immunosorbent assay(ELISA)to evaluate its metabolic capacity.Results During fermentation(3 h),titratable acidity of VD?-fortified yogurt initially increased,then decreased,and eventually stabilized with rising microcapsule dosage,while total solid content remained consistent.WHC exhibited an initial increase followed by a decline,whereas syneresis showed an inverse trend.At an optimal dosage of 3.75 μg/100 mL,the yogurt displayed a dense and uniform network structure,characterized by non-Newtonian fluid behavior with shear-thinning properties.This formulation demonstrated robust structural stability under high-frequency mechanical stress,alongside desirable textural,flavor,and sensory attributes.Animal experiments revealed that the serum concentrations of 25(OH)D3,1,25-(OH)2D3,calcium,and phosphorus in the vitamin D?-fortified yogurt intervention group were significantly higher than those in the tail-suspended control group(P<0.05).Conclusion VD? microencapsulation technology effectively preserves and enhances the nutritional quality characteristics of yogurt and mitigates vitamin D metabolic dysregulation under simulated weightlessness.

Objective To investigate the expression of cysteine rich protein 2 binding protein(CSRP2BP)mRNA and estrogen related receptors β(ESRRB)mRNA and protein in cervical cancer tissues and their correlation with epithelial mesenchymal transition(EMT)and clinical prognosis.Methods A total of 106 cervical cancer patients admitted to Yan'an Traditional Chinese Medicine Hospital from March 2018 to March 2020 were selected.Real time fluorescence quantitative PCR(RT-qPCR)was used to detect CSRP2BP mRNA,ESRRB mRNA and EMT related indicators[E-cadherin(E-cad),N-cadherin(N-cad),snail family transcriptional repressor 1(Snail)].Immunohistochemistry was used to detect the CSRP2BP protein and ESRRB protein expression in tissues.Pearson correlation analysis was used to analyze the correlation between CSRP2BP mRNA,ESRRB mRNA and EMT related indicators.Kaplan-Meier curve and COX regression were used to analyze the effect of CSRP2BP mRNA and ESRRB mRNA expression on the prognosis of cervical cancer patients.Results CSRP2BP mRNA(3.14±0.52 vs 1.22±0.21)expression and protein positive rate(86.79%vs 9.43%),ESRRB mRNA expression(2.86±0.31 vs 1.06±0.20)and protein positive rate(92.45%vs 8.49%),N-cad mRNA(3.22±0.43 vs 1.05±0.26)and Snail mRNA(2.67±0.36 vs 0.69±0.17)expression in cancer tissues were higher than those in adjacent tissues,while E-cad mRNA(0.84±0.17 vs 2.15±0.24)expression was lower than that in adjacent tissues,and the differences were statistically significant(t/x2=34.249,127.049;50.234,149.466;44.461,51.204,45.858,all P<0.001).The expression of CSRP2BP mRNA and ESRRB mRNA in cervical cancer was positively correlated with N-cad mRNA and Snail mRNA(r=0.663,0.731;0.726,0.715,all P<0.001),and was negatively correlated with E-cad mRNA(r=-0.594,-0.669,all P<0.001).The expression of CSRP2BP mRNA(4.48±0.36,4.21±0.37,4.69±0.33)and ESRRB mRNA(4.48±0.36,4.21±0.37,4.69±0.33)in cervical cancer tissues of patients with FIGO stage Ⅰ B2～Ⅱ A,poor differentiation and lymph node metastasis was higher than that of patients with FIGO stage ⅠA～ⅠB1(2.60±0.44,2.06±0.24),medium and high differentiation(2.43±0.44,2.01±0.25)and no lymph node metastasis(2.53±0.58,2.07±0.26),and the differences were statistically significant(t=16.327,41.135;18.507,36.545;14.501,43.806,all P<0.001).The 3-year overall survival rate of patients with high expression of CSRP2BP mRNA was 66.00%(33/50),which was lower than 89.29%(50/56)in the low expression group,while the 3-year overall survival rate of the high expression group of ESRRB mRNA was 65.38%(34/52),which was lower than 90.74%(49/54)of the low expression group,and the differences were statistically significant(Log rank x2=5.401,11.400,P=0.020,0.001).Multivariate Cox regression analysis showed that,CSRP2BP mRNA high expression(HR=1.327,95%CI:1.097～1.605),ESRRB mRNA high expression(HR=1.322,95%CI:1.108～1.577),FIGO stage Ⅰ B2～Ⅱ A(HR=1.423,95%CI:1.154～1.755),lymph node metastasis(HR=1.363,95%CI:1.095～1.698)and poor differentiation(HR=1.297,95%CI:1.064～1.581)were risk factors affecting the prognosis of cervical cancer patients(all P<0.001).Conclusion The increased expression of CSRP2BP mRNA and ESRRB mRNA in cervical cancer are related to EMT related indicators and adverse clinical and pathological features,and are new tumor markers for prognostic evaluation.

A retrospective analysis was made on the clinical data and gene mutation characteristics of 2 children admitted to the Children′s Hospital of Zhejiang University School of Medicine for epilepsy without periventricular nodules caused by the ARF1 gene mutation from August 2023 to February 2024, and relevant literature was reviewed.Both patients presented with seizures and psychomotor retardation, and 1 of them was diagnosed with West syndrome.Whole exome sequencing confirmed that the 2 patients carried a missense mutation in the ARF1 gene (c.55C>A, p.R19S).Brain magnetic resonance imaging (MRI) of 2 patients revealed no obvious abnormalities.A summary analysis of 5 cases of ARF1 gene mutations reported in three foreign literatures showed that patients with ARF1 gene mutations usually presented with seizures, developmental delay, hypotonia, mental retardation, and motor stereotypies.MRI showed periventricular nodular heterotopia, corpus callosum dysplasia, subcortical white matter abnormalities, and delayed myelination.This study found for the first time that ARF1-related disorders can occur without significant brain structural malformations, indicating that there are inconsistencies in neuroimaging findings, adding valuable phenotypic information to this gene.The differences in imaging findings may be the result of genetic background or variation in ARF1-interacting proteins, or may be caused by altered regulatory mechanisms of protein activity.

Objective: To develop a method for generating three-dimensional (3D) digital models of the periodontal ligament (PDL) using 3D cone-beam computed tomography (CBCT) reconstruction and to evaluate the accuracy and agreement of the 3D PDL models in the measurement of periodontal bone loss. Methods: CBCT data collected from four patients with skeletal Class III malocclusion prior to periodontal surgery were reconstructed at three voxel sizes (0.2 mm, 0.25 mm, and 0.3 mm), and 3D tooth and alveolar bone models were generated to obtain digital PDL models for the maxillary and mandibular anterior teeth. Linear measurements of the alveolar bone crest obtained during periodontal surgery were compared with the digital measurements for assessment of the accuracy of the digital models. The agreement and reliability of the digital PDL models were analyzed using intra- and interexaminer correlation coefficients and Bland–Altman plots. Results: Digital models of the maxillary and mandibular anterior teeth, PDL, and alveolar bone of the four patients were successfully established. Relative to the intraoperative measurements, linear measurements obtained from the 3D digital models were accurate, and there were no significant differences among different voxel sizes at different sites. High diagnostic coincidence rates were found for the maxillary anterior teeth. The digital models showed high intra- and interexaminer agreement. Conclusions Digital PDL models generated by 3D CBCT reconstruction can provide accurate and useful information regarding the alveolar crest morphology and facilitate reproducible measurements. This could assist clinicians in the evaluation of periodontal prognosis and establishment of an appropriate orthodontic treatment plan.

BACKGROUND: Massive bleeding is the main concern for the management of placenta percreta (PP). Intra-abdominal aortic balloon occlusion (IABO) is one method for pelvic devascularization, but the efficacy of IABO is uncertain. This study aims to investigate the outcomes of IABO in PP patients. METHODS: We retrospectively reviewed the clinical data of PP cases from six tertiary centers in China between January 2011 and December 2015. PP cases with/without the use of IABO were analyzed. Propensity score matching analysis was performed to reduce the effect of selection bias. Postpartum hemorrhage (PPH) and the rate of hysterectomy, as well as neonatal outcomes, were analyzed. RESULTS: One hundred and thirty-two matched pairs of patients were included in the final analysis. Compared with the control group, maternal outcomes, including PPH (68.9% vs. 87.9%, χ2 = 13.984, P < 0.001), hysterectomy (8.3% vs. 65.2%, χ2 = 91.672, P < 0.001), and repeated surgery (1.5% vs. 12.1%, χ2 = 11.686, P = 0.001) were significantly reduced in the IABO group. For neonatal outcomes, Apgar scores at 1 minute (8.67 ± 1.79 vs. 8.53 ± 1.68, t = -0.638, P = 0.947) and 5 minutes (9.43 ± 1.55 vs. 9.53 ± 1.26, t = 0.566, P = 0.293) were not significantly different between the two groups. CONCLUSIONS IABO can significantly reduce blood loss, hysterectomies, and repeated surgeries. This procedure has not shown harmful effects on neonatal outcomes.

The clinical data of a case with late-onset isolated sulfite oxidase deficiency(ISOD)admitted in the Department of Neurology, Children′s Hospital, Zhejiang University School of Medicine in July 2021 were retrospectively analyzed.Fifteen previously published cases of late-onset ISOD were also reviewed.The patient was a girl, who was hospitalized because of " motor regression with mental retardation for 5 days" at 1 year old.The manifestations of the patient were extrapyramidal symptoms, regression of motor development and seizures.The level of urinary sulfites in the patient was increased.Magnetic resonance imaging (MRI) features were bilateral pallidus and substantia nigra.Gene sequencing suggested a pure missense mutation of the sulfite oxidase( SUOX) gene c. 650(exon5)G>A(p.Arg217Gln). In 16 cases of late-onset ISOD, the median age at onset and diagnosis was 10.5 months and 34.0 months, respectively.The common clinical manifestations were hypotonia (13 cases), seizures (10 cases), movement disorders (9 cases), and ectopia lentis (6 cases). The most common brain MRI feature was pallidus changes (11 cases), followed by lesions of substantia nigra (5 cases), and cerebral atrophy (4 cases). Fourteen cases of late-onset ISOD showed a positive urinary sulfite test.The missense mutation of the SUOX gene was found in 9 cases.It suggested that brain MRI involvement of bilateral pallidus, high excretion of urine sulfites and the missense mutation of the SUOX gene were important diagnostic clues for late-onset ISOD.
