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.

Cancer is a major chronic disease that threatens human health, while traditional Chinese medicine (TCM) is a unique method for cancer prevention and treatment in China. After about 70 years of innovation and development, TCM has made constant progress in areas such as the clinical diagnosis, treatment, evidence-based researches, and mechanism exploration of cancer. It has special advantages in aspects such as reducing toxicity, enhancing treatment efficacy, managing symptoms, accelerating recovery, preventing recurrence and metastasis, and prolonging advanced-stage survival. However, there are still bottlenecks for TCM in cancer care. This paper cuts in the key links between TCM and western medicine in their combined application in cancer prevention and treatment, and take the original TCM theories on cancer as the lead, high-quality evidence-based researches as the drive, and analysis on the dynamic mechanism as the core, to show the advantages and effects of TCM in cancer treatment in an all-round way. It also aims to provide novel strategies for sustainable and innovative development and for formulation of comprehensive schemes that integrate TCM and western medicine for cancer prevention and treatment.

ObjectiveTo explore the distribution characteristics of traditional Chinese medicine （TCM） syndromes in postoperative gastric cancer patients， and to analyse the factors associated with yang deficiency syndrome and its severity. MethodsTotally， 173 patients who underwent postoperative gastric cancer surgery and were treated in four centers nationwide from February 22， 2022 to March 21， 2023， were enrolled. General information and TCM syndromes were collected， and Diagnostic Scale for Yang Deficiency Syndrome in Gastric Malignancies was filled in. The frequency of TCM syndromes after gastric cancer surgery was analyzed， and univariate analysis and multivariate logistic regression analysis were performed on the related factors of yang deficiency syndrome versus non-yang deficiency syndrome and between different severity of yang deficiency syndrome. ResultsThe most common syndrome after gastric cancer surgery was qi deficiency （95 cases， 54.91%）， followed by yang deficiency （87 cases， 50.29%）. Patients with yang deficiency syndrome were often suffered from qi deficiency， qi stagnation， and phlegm dampness syndrome. Comparing yang deficiency syndrome with non-yang deficiency syndrome， univariate analysis showed that history of alcohol consumption， pathological stage， degree of differentiation， Lauren grade， signet ring cell carcinoma， vascular cancer thrombus， and nerve invasion were statistically significant （P＜0.05）； and multivariate logistic regression analysis showed that history of alcohol consumption， signet ring cell carcinoma， pathological stage Ⅲ， Ⅳ， and vascular cancer thrombus may be correlated with yang deficiency syndrome in postoperative gastric cancer patients （P＜0.05）. The univariate analysis showed that age， pathological stage， precancerous lesions， and body mass index grade were significantly different when compared between mild and severe yang deficiency syndrome （P＜0.05）； multivariate logistic regression analysis showed that age， low body weight， and pathological stage Ⅲ and Ⅳ might be correlated with severe yang deficiency syndrome after gastric cancer surgery （P＜0.05）. ConclusionQi deficiency and yang deficiency are common TCM syndromes in postoperative patients with gastric cancer. Alcohol consumption history， pathological staging （stage Ⅲ and Ⅳ）， signet ring cell carcinoma， and the presence of vascular cancer thrombus may be correlated with the occurrence of yang deficiency syndrome， and higher age， low body weight， and pathological staging （stage Ⅲ and Ⅳ） may be the correlates of severe yang deficiency syndrome.

ObjectiveTo explore the therapeutic mechanism of Bushen Huoxue prescription from the perspective of bone metabolism by observing the clinical efficacy of this prescription in treating femoral head necrosis （ONFH， syndrome of liver and kidney deficiency） and its influences on bone metabolism indexes： N-terminal propeptide （PINP） and β-collagen degradation product （β-CTX）. MethodSixty-six ONFH patients with the syndrome of liver and kidney deficiency in Zhengzhou Traditional Chinese Medicine Hospital of Orthopedics from December 2021 to September 2022 were selected. The patients were randomized into an experimental group and a control group by the parallel control method， with 33 patients in each group. The experimental group received Bushen Huoxue prescription orally， while the control group received Xianlinggubao Capsules orally， with a treatment cycle of 6 months. The visual analogue scale （VAS） score， Harris score， Association Research Circulation Osseous （ARCO） staging， imaging changes， quantitative scores of TCM symptoms， and serum levels of PINP and β-CTX were determined before and after treatment. The occurrence of adverse events and reactions was recorded. ResultThe total response rate in the experimental group was 83.87% （26/31）， which was higher than that （68.75%， 22/32） in the control group （Z=-2.096， P<0.05）. After treatment， the single and total scores of TCM symptoms， VAS score， and β-CTX level decreased in the two groups （P<0.05）. Moreover， the decreases in the scores of hip pain， lower limb mobility， soreness of waist and knees， and lower limb flaccidity， total score of TCM symptoms， VAS score， and β-CTX level in the experimental were larger than those in the control group （P<0.05）. After treatment， the imaging results showed no significant improvement in the two groups. The Harris score and PINP level in both groups increased after treatment （P<0.05）， and the increases were more obvious in the experimental group than in the control group （P<0.05）. No serious adverse event or adverse reaction appeared during the observation period. ConclusionBushen Huoxue prescription can relieve pain and TCM symptoms and improve the hip joint function in treating ONFH patients with the syndrome of liver and kidney deficiency. It can inhibit the development of ONFH， increase PINP， and decrease β-CTX. No obvious side effect appears during the clinical observation period， which shows that Bushen Huoxue prescription has good safety.

Osteoarthritis(OA),characterized by cartilage degeneration,synovial inflammation,and subchondral bone remodeling,is among the most common musculoskeletal disorders globally in people over 60 years of age.The initiation and progression of OA involves the abnormal metabolism of chondrocytes as an important pathogenic process.Cartilage degeneration features mitochondrial dysfunction as one of the important causative factors of abnormal chondrocyte metabolism.Therefore,maintaining mitochondrial homeostasis is an important strategy to mitigate OA.Mitophagy is a vital process for autophagosomes to target,engulf,and remove damaged and dysfunctional mitochondria,thereby maintaining mitochondrial homeostasis.Cumulative studies have revealed a strong association between mitophagy and OA,suggesting that the regulation of mitophagy may be a novel therapeutic direction for OA.By reviewing the literature on mitophagy and OA published in recent years,this paper elaborates the potential mechanism of mitophagy regulating OA,thus providing a theoretical basis for studies related to mitophagy to develop new treatment options for OA.

The endoplasmic reticulum is a key site for protein production and quality control.More than one-third of proteins are synthesized and folded into the correct three-dimensional conformation in the endoplasmic reticulum.However,during protein folding,unfolded and/or misfolded proteins are prone to occur,which may lead to endoplasmic reticulum stress.Organisms can monitor the quality of the proteins produced by endoplasmic reticulum quality control(ERQC)and endoplasmic reticulum-associated degradation(ERAD),which maintain endoplasmic reticulum protein homeostasis by degrading abnormally folded proteins.The underlying mechanisms of protein folding and ERAD in mammals have not yet been fully explored.Therefore,this paper reviews the process and function of protein folding and ERAD in mammalian cells,in order to help clinicians better understand the mechanism of ERAD and to provide a scientific reference for the treatment of diseases caused by abnormal ERAD.

Objective:To describe the distribution of fat-free mass (FFM) and fat-free mass index (FFMI) in children aged 3-17 years in China.Methods:Data were collected from National Nutrition and Health Systematic Survey in 0-18 years old children in China. By using multi-stage stratified randomized cluster sampling method, the project was conducted in 28 survey points in urban and rural areas in 14 provinces (autonomous regions and municipalities) in 7 regions in China from 2019 to 2021. FFM was measured using bioelectrical impedance meter. Finally, the body composition data of 70 853 children were included in the analysis. M ( Q1, Q3) was used to describe the gender and age specific FFM and FFMI of the children in different regions. Kruskal-Wallis H rank sum test was used to compare FFM and FFMI of boys and girls in same age group, boys in different age groups, girls in different age groups, as well as boys in same age group and girls in same age group in different regions. DSCF method was used for pairwise comparisons. Results:After the age of 11 years, the difference of FFMI between boys and girls increased year by year. The FFMI was 14.2 kg/m 2 in boys and 13.8 kg/m 2 in girls at 11 years old, the difference was significant ( χ2=135.86, P<0.001). The difference of FFMI between boys and girls exceed 1.0 kg/m 2 from 12 years old, and FFMI was 15.3 kg/m 2 in boys and 14.2 kg/m 2 in girls at 12 year old, the difference was significant ( χ2=597.27, P<0.001). The FFMI was 17.5 kg/m 2 in boys and 14.7 kg/m 2 in girls at 16 years old, the difference was significant ( χ2=2 543.60, P<0.001). The FFMI was higher in boys in northeast China, while the FFMI was lower in both boys and girls in northwest China. Conclusions:Gender specific difference was observed in the increase of FFMI with age. The FFMI was significantly higher in boys than in girls after 11 years old. It is necessary to pay attention to the problem of FFM in children in northeastern and northwestern China.

Objective:To investigate the distribution characteristics of body height, body weight and body mass index (BMI) in children aged 3-17 years in China.Methods:Data were obtained from the National Nutrition and Health Systematic Survey in 0-18 years old children in China. The study selected 70 853 children aged 3-17 years from 28 urban and rural survey sites in 14 provinces (autonomous regions and municipalities) in 7 regions of China with multi-stage stratified cluster random sampling. M ( Q1, Q3) was used to describe the region, age and gender specific body height, body weight and BMI in the children aged 3-17 years. Wilcoxon rank sum test was used to compare the body height, body weight, and BMI between boys and girls in same age group. Kruskal-Wallis H rank sum test was used to compare the body height, body weight and BMI among boys in different age groups and among girls in different age groups, as well as among boys in same age group and among girls in same age group from different regions, and DSCF method was used for further pairwise comparisons. Results:In this study, the median body height and body weight were 172.0 cm and 62.9 kg in 17-year-old boys and 160.0 cm and 53.7 kg in 17-year-old girls. The median for children's body height, body weight, and BMI in most age groups were higher in northeastern and northern China than in southern China, and the differences could be observed until age 17 years. The differences in body weight and BMI in children in northeastern and northern China were greater in Q3 than in Q1 compared with southern China. Conclusions:The body height of children aged 3-17 years continues to increase in China. Northeastern and northern China have more children with higher bodyweight, showing an obvious body weight increase trend, to which close attention needs to be paid.
