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.

Aim To analyze the correlation between serum retinol-binding protein 4(RBP4),low density lipo-protein cholesterol to albumin ratio(LDLC/Alb),monocyte to high density lipoprotein ratio(MHR)and plaque stability in carotid atherosclerosis population and their predictive value for acute ischemic stroke(AIS).Methods A total of 197 patients with asymptomatic carotid atherosclerosis admitted to our hospital from September 2021 to January 2023 were selected for a prospective cohort study,and they were categorized into occurred group and non-occurred group according to whether AIS occurred within 12 months.Baseline information at time of visit,results of the cervical ultrasonography and serum RBP4,LDLC/Alb,MHR levels were compared between the two groups.Spearman/Pearson and receiver operating characteristic(ROC)curve were used to analyze the corr-elation of RBP4,LDLC/Alb and MHR with carotid atherosclerosis and plaque stability,and the value of predicting AIS in carotid atherosclerosis population.Hosmer-Lemeshow goodness of fit test was used to evaluate the calibration ability of serum RBP4,LDLC/Alb and MHR to jointly predict AIS in carotid atherosclerosis population.Results The carotid intima-media thickness(IMT)was higher in occurred group than that in non-occurred group.There were more soft plaques and mixed plaques in occurred group than in non-occurred group(P＜0.05).Serum levels of RBP4,LDLC/Alb and MHR were higher in occurred group than those in non-occurred group(P＜0.05).The correlation analysis showed that the levels of serum RBP4,LDLC/Alb and MHR were positively correla-ted with IMT(r=0.803,0.740,0.710)and plaque properties(r=0.736,0.685,0.703)(P＜0.001).ROC curve a-nalysis showed that the AUC of serum RBP4,LDLC/Alb and MHR in predicting AIS in carotid atherosclerosis population was 0.796,0.821 and 0.828,respectively,and the AUC of MHR was the largest;the AUC of the combination of serum RBP4,LDLC/Alb and MHR was 0.936,which was higher than that of MHR(Z=2.978,P＜0.05),the predictive sensi-tivity and specificity were 88.24％and 87.40％.Hosmer-Lemeshow goodness of fit test showed that there was no signifi-cant difference between serum RBP4,LDLC/Alb and MHR in predicting AIS and the actual observation value in carotid atherosclerosis population(P＞0.05),and the prediction model had good calibration ability.Conclusion Serum RBP4,LDLC/Alb,and MHR are positively correlated with carotid atherosclerosis and plaque stability,and can predict the occurrence of AIS.Combined detection of the three can be used as a method for early identification of potential high-risk populations for AIS,providing a new,quantifiable guidance scheme for the prevention and treatment of AIS in carotid ath-erosclerotic population.

Radiotherapy (RT) can potentially induce systemic immune responses by initiating immunogenic cell death (ICD) of tumor cells. However, RT-induced antitumor immunologic responses are sporadic and insufficient against cancer metastases. Herein, we construct multifunctional self-sufficient nanoparticles (MARS) with dual-enzyme activity (GOx and peroxidase-like) to trigger radical storms and activate the cascade-amplified systemic immune responses to suppress both local tumors and metastatic relapse. In addition to limiting the Warburg effect to actualize starvation therapy, MARS catalyzes glucose to produce hydrogen peroxide (H₂O₂), which is then used in the Cu⁺-mediated Fenton-like reaction and RT sensitization. RT and chemodynamic therapy produce reactive oxygen species in the form of radical storms, which have a robust ICD impact on mobilizing the immune system. Thus, when MARS is combined with RT, potent systemic antitumor immunity can be generated by activating antigen-presenting cells, promoting dendritic cells maturation, increasing the infiltration of cytotoxic T lymphocytes, and reprogramming the immunosuppressive tumor microenvironment. Furthermore, the synergistic therapy of RT and MARS effectively suppresses local tumor growth, increases mouse longevity, and results in a 90% reduction in lung metastasis and postoperative recurrence. Overall, we provide a viable approach to treating cancer by inducing radical storms and activating cascade-amplified systemic immunity.

Objective: To explore the phenotypic and genotypic characteristics in Chinese children with classic pantothenate kinase-associated neurodegeneration (PKAN). Method: The clinical, radiographic and genetic data of all PKAN patients diagnosed at pediatric department of Peking University First Hospital from November 2006 to December 2016 were retrospectively collected and analyzed. Result: Twenty patients with classic PKAN were included in the study. The median age at onset was 3.5 years (ranging from 1.0 to 10.0 years), and the most common initial symptom was gait disturbance (16 cases). At the last evaluation, the clinical features were limbs dystonia (20 cases), dysarthria (16 cases), dysphagia (11 cases), pyramidal sign (7 cases), mental regression (3 cases) and pigmentary retinopathy (5 cases). For those classic PKAN patients, the median time from onset of disease to loss of independent ambulation was 6.9 years (ranging from 2.0 to 12.0 years). Imaging data showed, except "eye of tiger" in MRI (19 cases), globus pallidus calcification in CT was also found in four patients. In gene testing, 26 different mutations in PANK2 gene were identified, and 16 of 26 were novel mutations. Moreover, c. 1502T>C (p.Ile501Asn) was the most common mutation (4 cases). Conclusion Dystonia is the major neurologic feature of classic PKAN. Disease progression is rapid, with loss of independent ambulation within 10 years after onset. Except "eye of tiger" in MRI, globus pallidus calcification in CT may be another imaging feature of PKAN.Sixteen novel mutations of PANK2 gene were identified in the study.
