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.

The prevalence of Class III malocclusion varies among different countries and regions. The populations from Southeast Asian countries (Chinese and Malaysian) showed the highest prevalence rate of 15.8%, which can seriously affect oral function, facial appearance, and mental health. As anterior crossbite tends to worsen with growth, early orthodontic treatment can harness growth potential to normalize maxillofacial development or reduce skeletal malformation severity, thereby reducing the difficulty and shortening the treatment cycle of later-stage treatment. This is beneficial for the physical and mental growth of children. Therefore, early orthodontic treatment for Class III malocclusion is particularly important. Determining the optimal timing for early orthodontic treatment requires a comprehensive assessment of clinical manifestations, dental age, and skeletal age, and can lead to better results with less effort. Currently, standardized treatment guidelines for early orthodontic treatment of Class III malocclusion are lacking. This review provides a comprehensive summary of the etiology, clinical manifestations, classification, and early orthodontic techniques for Class III malocclusion, along with systematic discussions on selecting early treatment plans. The purpose of this expert consensus is to standardize clinical practices and improve the treatment outcomes of Class III malocclusion through early orthodontic treatment.

Patients with periodontal disease often require combined periodontal-orthodontic interventions to restore periodontal health, function, and aesthetics, ensuring both patient satisfaction and long-term stability. Managing these patients involving orthodontic tooth movement can be particularly challenging due to compromised periodontal soft and hard tissues, especially in severe cases. Therefore, close collaboration between orthodontists and periodontists for comprehensive diagnosis and sequential treatment, along with diligent patient compliance throughout the entire process, is crucial for achieving favorable treatment outcomes. Moreover, long-term orthodontic retention and periodontal follow-up are essential to sustain treatment success. This expert consensus, informed by the latest clinical research and practical experience, addresses clinical considerations for orthodontic treatment of periodontal patients, delineating indications, objectives, procedures, and principles with the aim of providing clear and practical guidance for clinical practitioners.

Objective:To investigate the iodine nutrition level and the prevalence of thyroid nodules in pregnant women in Hubei Province, and to provide a basis for prevention and treatment of iodine deficiency disorders.Methods:According to the requirements of the National Iodine Deficiency Disorders Monitoring Program (2016 Edition), a cross-sectional survey of iodine nutrition status of pregnant women ( n = 321) was conducted from July to October 2020 in two mountainous counties (Tongcheng County and Xingshan County) and two plain counties (Liangzihu District and Xinzhou District) in Hubei Province. Among them, there were 43, 114, and 164 pregnant women in the early, middle, and late stages of pregnancy, respectively. Edible salt samples and once random urine samples were collected to detect salt iodine and urinary iodine, and thyroid ultrasound was performed to calculate the detection rate of thyroid nodules. Results:The coverage rate of iodized salt, qualified rate of iodized salt, and consumption rate of qualified iodized salt in Hubei Province were 99.69% (320/321), 95.94% (307/320) and 95.64% (307/321), respectively. The median urinary iodine level for pregnant women was 164.80 μg/L. Among them, the median urinary iodine levels in Liangzihu District, Tongcheng County, Xinzhou District, and Xingshan County were 175.90, 178.25, 155.80 and 143.00 μg/L, respectively. There was a statistically significant difference in urinary iodine levels among different regions ( H = 8.51, P = 0.037). The median urinary iodine levels of pregnant women in the early, middle, and late stages of pregnancy were 187.20, 144.45, and 172.05 μg/L, respectively. There was no statistically significant difference in urinary iodine levels among pregnant women in different stages of pregnancy ( H = 2.94, P = 0.230). Urinary iodine < 150, 150 - < 250, 250 - < 500, ≥500 μg/L accounted for 45.48% (146/321), 33.33% (107/321), 19.63% (63/321), 1.56% (5/321), respectively. The detection rate of thyroid nodules was 16.82% (54/321), and the goiter rate was 0.93% (3/321). Conclusions:In 2020, Hubei Province is in an appropriate state of iodine, and there are still a considerable proportion of pregnant women in a state of iodine deficiency. The detection rate of thyroid nodules is relatively low. It is necessary to continuously monitor the iodine nutrition of pregnant women, strengthen health promotion on the hazards of iodine deficiency during pregnancy, and minimize maternal and infant health damage caused by iodine deficiency.

OBJECTIVE To predict the core ingredients, targets and signaling pathways of Sanhuang ointment in the treatment of haemorrhoids based on network pharmacology, and preliminarily discuss the mechanism of action preliminarily by means of molecular docking and experimental verification. METHODS Active ingredients, targets and haemorrhoid related targets of Sanhuang ointment were obtained through literature research and database screening. Association networks were constructed and core targets were screened by Cytoscape, and gene function analysis and pathway enrichment analysis were conducted. Autodock Vina was used for molecular docking verification, and the regulatory effects of Sanhuang ointment on core targets were verified by ELISA and immunohistochemistry. RESULTS The 77 active ingredients and 61 potential targets of Sanhuang ointment for treating haemorrhoids were collected. KEGG showed that Sanhuang ointment could regulate calcium signaling pathways, neuroactive ligand receptor interactions, cGMP-PKG pathway, etc. Affect 6 core targets of CGRP, NK-1R, TRPV1, VEGF, IL-6 and TNF-α. Molecular docking showed that Sanhuang ointment had a good affinity with target protein, and animal experiments verified that Sanhuang ointment could inhibit the expression of IL-6, CGRP, substance P, and promote the expression of VEGF. CONCLUSION Sanhuang ointment may act on CGRP, NK-1R and other targets, regulate Calcium signaling pathway and PI3K-Akt pathways, and exert analgesic and anti-inflammatory effects, promoting blood circulation and removing blood stasis to treat haemorrhoids.

Objective:To investigate the iodine nutrition level and thyroid function status of pregnant women in Hubei Province.Methods:According to the requirements of "the National Iodine Deficiency Disorders Monitoring Program (2016 Edition)", in 2020, using a cross-sectional survey method, two mountainous counties and two plain areas in Hubei Province were divided into five districts: east, west, south, north, and central. One township (street) was selected from each district, and 20 pregnant women were selected from each township (street) as survey subjects. Urine iodine content and thyroid function indicators [serum free triiodothyronine (FT 3), free thyroxine (FT 4), thyroid-stimulating hormone (TSH), thyroid peroxidase antibody (TPOAb), thyroglobulin antibody (TgAb)] were tested. Abnormal thyroid function rate and antibody positive rate were analyzed, and correlation analysis of thyroid function indicators was conducted (Spearman method). Results:A total of 321 pregnant women were included, including 43, 114, and 164 in early, middle, and late pregnancy, respectively; The median urinary iodine was 164.80 μg/L. The median serum FT 3, FT 4, TSH, TPOAb, TgAb levels were 4.10, 12.83 pmol/L, 1.85 mU/L, 15.84 and 13.35 U/ml, respectively. There were statistically significant differences in FT 3, FT 4, and TSH levels among different trimesters ( P < 0.05). According to Spearman's correlation analysis, FT 3 in early stage of pregnancy was negatively correlated with TSH and TPOAb levels ( r = - 0.46, - 0.33, P < 0.05), while TSH was positively correlated with TPOAb level ( r = 0.33, P = 0.032); there was a positive correlation between FT 4 and TgAb levels in middle stage of pregnancy ( r = 0.21, P = 0.032); there was a negative correlation between FT 3 and TPOAb levels in late stage of pregnancy ( r = - 0.19, P = 0.017); FT 3 and FT 4, TPOAb and TgAb levels were positively correlated throughout pregnancy ( P < 0.05). There was no correlation between urinary iodine content and thyroid function indicators ( P > 0.05). The total abnormal rate of thyroid function was 7.79% (25/321), with 16.28% (7/43), 5.26% (6/114), and 7.32% (12/164) in early, middle, and late pregnancy, respectively. There was no statistically significant difference in the abnormal rate of thyroid function among different pregnancy periods (χ 2 = 4.83, P = 0.097). The detection rates of hypothyroxinemia, hypothyroidism, subclinical hypothyroidism, hyperthyroidism, and subclinical hyperthyroidism were 4.36% (14/321), 0.31% (1/321), 2.49% (8/321), 0.31% (1/321), and 0.31% (1/321), respectively. The positive detection rate of autospecific antibodies was 10.28% (33/321), with a TPOAb positive detection rate of 9.97% (32/321) and a TgAb positive detection rate of 5.30% (17/321). Conclusions:The iodine nutrition level of pregnant women in Hubei Province is at a suitable level, and the rates of abnormal thyroid function and thyroid autospecific antibody positive are relatively low. It is necessary to continuously monitor the iodine nutrition and thyroid function indexes of pregnant women, strengthen health education on the hazards of iodine deficiency during pregnancy, and minimize the harm to maternal and infant health caused by iodine deficiency.

Objective: The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population. Methods: The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models. Results: A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices). Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.
