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 assess the clinical value of a nomogram model constructed by the authors in predicting recurrent laryngeal nerve(RLN)injury after thermal ablation for secondary hyperparathyroidism(SHPT).Methods The clinical data of a total of 102 patients with end-stage renal disease SHPT,who received thermal ablation at the Yulin Municipal First People's Hospital of China from May 2019 to January 2024,were retrospectively analyzed.According to whether RLN injury occurred or not after thermal ablation,the patients were divided into RLN injury group(n=24)and non-RLN injury group(n=78).The clinical data were compared between the two groups.Multivariate logistic regression analysis was used to determine the independent risk factors for RLN injury.R language was used to construct a visualization nomogram according to the variables of the logistic regression model.The receiver operating characteristic(ROC)curve was used to evaluate the discrimination of the nomogram model.Hosmer-Lemeshow test and calibration curve were used to evaluate the goodness of fit and the calibration of the nomogram model.Results Superior gland ablation(OR=8.784,95％ CI:2.056-37.521,P=0.003),total parathyroid gland volume(OR=1.684,95％CI:1.167-2.430,P=0.005),thermal ablation energy(OR=1.132,95％ CI:1.016-1.261,P=0.025)were the independent risk factors for RLN injury after thermal ablation(all P＜0.05).Based on the above 3 risk factors,a nomogram model used for predicting the risk of RLN injury was established.The area under ROC curve(AUC)was 0.868,and the Hosmer-Lemeshow test showed that the degree of fit was good(P=0.769).The calibration curve indicated that the calibration curve basically coincided with the ideal curve.Conclusion Superior gland ablation,total parathyroid gland volume,and thermal ablation energy are the independent risk factors for RLN injury after thermal ablation in patients with end-stage renal disease SHPT.The nomogram model constructed based on the above mentioned three factors can effectively predict RLN injury.

Purpose To investigate the risk factors of severe hypocalcemia after ultrasound-guided thermal ablation for secondary hyperparathyroidism.Materials and Methods A retrospective case-control study was used to study 91 patients with uremia complicated with secondary hyperparathyroidism in the First People's Hospital of Yulin from May 2019 to May 2023.All patients underwent ultrasound-guided thermal ablation and were divided into severe hypocalcemia group(SH)and non-SH group according to postoperative blood calcium levels.The difference of clinical data between the two groups was compared,and the independent risk factors of SH were investigated by multivariate Logistic regression analysis.Results A total of 317 glands were ablated in 49 cases of microwave ablation and 42 cases of radiofrequency ablation.SH occurred in 57 cases(62.64%)after ablation.The comparison of clinical data between the two groups showed that there were significant differences in the preoperative intact parathyroid hormone(iPTH),decline rate of iPTH 1 d,preoperative serum alkaline phosphatase,the proportion of parathyroid glands≥4 and the total gland volume between the two groups(all P<0.05).Receiver operating characteristic curve analysis was used to obtain the best cut-off point of iPTH 1 d decline rate,the result was 74.59%,the area under the curve was 0.866(95%CI 0.787-0.945)(P<0.05),the sensitivity was 84.2%,and the specificity was 78.1%.Multivariate Logistic regression analysis showed that preoperative alkaline phosphatase(OR=1.015,95%CI 1.005-1.025,P=0.030)and decline rate of iPTH 1 d≥74.59%(OR=30.423,95%CI 5.938-155.858,P<0.001)and parathyroid glands≥4(OR=4.355,95%CI 1.027-18.469,P=0.046)were independent risk factors for postoperative SH(all P<0.05).Conclusion Preoperative alkaline phosphatase and decline rate of iPTH 1 d≥74.59%and the number of parathyroid glands≥4 are independent risk factors for SH after thermal ablation.

Objective To observe the risk factors of recurrence after ultrasound-guided thermal ablation for treating uremia secondary hyperparathyroidism(SHPT).Methods Totally 59 patients with uremia SHPT who underwent ultrasound-guided thermal ablation were enrolled,including 23 cases with(relapse group)and 36 without SHPT recurrence(non relapsed group).Clinical data were compared between groups,univariate and multivariate logistic regression analysis were performed to screen independent risk factors of SHPT recurrence.Results There were significant differences of serum free thyroxine(FT4),urea,intact parathyroid hormone(iPTH)1 day after ablation,1 day decrease rate of iPTH,the maximum diameter of the largest nodule,ablation time,total ablation energy,energy to volume ratio and the proportion of 1 day decrease rate of iPTH≤90%between groups(all P＜0.05).Higher urea,lower energy to volume ratio and 1 day decrease rate of iPTH≤90%were all independent risk factors of SHPT recurrence(all P＜0.05).Conclusion Higher urea,lower energy to volume ratio and 1 day decrease rate of iPTH≤90%were independent risk factors of recurrence after ultrasound-guided thermal ablation for treating uremia SHPT.

Objective To investigate the relationship between sleep duration and obesity, and the risk of common chronic diseases in the occupational population in Shanghai City. Methods A total of 18 775 occupational individuals were selected as the study subjects using convenience sampling method in Shanghai City. Data on personal lifestyle behaviors and medical examination results were collected. The relationship between sleep duration and different types of obesity with dyslipidemia, hyperuricemia, hypertension, and hyperglycemia was analyzed. Results The incidence of dyslipidemia, hyperuricemia, hypertension, and hyperglycemia among the study subjects was 24.9%, 16.2%, 11.5%, and 7.3%, respectively. The incidence of these four chronic diseases were higher in individuals with central obesity and suboptimal sleep compared to the control group (all P<0.01). Multivariate logistic regression analysis showed that suboptimal sleep combined with general obesity/overweight increased the risk of dyslipidemia, hyperuricemia, hypertension, and hyperglycemia in the study subjects ［odds ratio (OR) were 2.40, 3.47, 3.30, and 2.79, respectively; all P<0.01］, after adjusting for age, gender, education level, marital status, occupation type, labor intensity, smoking, and drinking. Suboptimal sleep combined with central obesity also potentially increased the risk of these four chronic diseases (OR were 2.25, 3.09, 3.09, and 2.98, respectively; all P<0.01). Conclusion The incidence of common chronic diseases is relatively high in the occupational population in Shanghai City. Suboptimal sleep combined with different types of obesity increases the risk of common chronic diseases.

Objective:To understand the relationship between the RNA shedding time of SARS-CoV-2 infected persons and the single nucleotide mutation of the virus, the population of infected persons, underlying diseases and other factors, so as to provide more clues for the study of SARS-CoV-2 infection dynamics.Methods:The data of epidemiology, clinical manifestations, and underlying diseases of infected persons in a cluster epidemic of COVID-19 in Jiangsu province from July to September 2021 were collected. Nasopharyngeal swab samples of cases were collected, and the whole genome of the virus was sequenced by second-generation sequencing technology. The online analysis platform was used to judge the virus type and analyze the mutation site, and Cox proportional risk model was used to analyze the relationship between the RNA shedding time of SARS-CoV-2 and various research factors.Results:There were 350 persons who finally obtained the whole genome sequence of the virus in this COVID-19 outbreak, of which 60.3% were female, the median age was 49 years old (interquartile range, IQR: 37-65 years old)), and the median time of virus shedding was 33 days ( IQR, 26-44 days). The whole-genome sequencing analysis showed that compared with the Wuhan reference strain sequence, the infected persons’ sequence had 34~41 nucleotide mutation sites, belonging to VOC/Delta variant (B.1.617.2 evolutionary branch), and C346T, C1060T, T2803C, T7513C, A29681C were the main single nucleotide polymorphisms (SNPs) of this epidemic. Cox regression analysis showed that age, underlying disease, clinical classification, vaccination, SNP T2803C and T7513C had an impact on the RNA shedding time of SARS-CoV-2. The adjusted multivariate Cox regression result showed that age [ HR=0.73, 95% CI (0.55, 0.95)] and T7513C [ HR=0.37, 95% CI (0.18, 0.77)] were still the risk factors for the extension of SARS-CoV-2 RNA shedding time. Conclusions:This study analyzed the effects of the individual factors and viral single nucleotide variations on the time of viral RNA shedding. Those who were older, suffered from hypertension, had more severe clinical symptoms, were not vaccinated or incompletely vaccinated, and had T7513C mutation in the infected virus, had a risk of a long RNA shedding time of SARS-CoV-2, which should be given special attention and follow-up after rehabilitation.

Objective : To investigate the effects of Lin28 overexpression on the proliferation and osteogenic differentiation of human dental pulp stem cells (hDPSCs) through mTOR signaling pathway. Methods : After transfecting lentiviral vectors of Lin28 gene in hDPSCs , the relative expression of Lin28 was detected by Real⁃time PCR. CCK⁃8 assay was applied to detect the effect on cell proliferation. qRT⁃PCR was used to research the expression levels of alkaline phosphatase (ALP) , osteopontin (OPN) and osteocalcin (OCN) . Western blot assay was processed to investigate the effects on the relative expression levels of ALP and OPN proteins. Alizarin red staining was utilized to detect the mineralized nodules. Results : Compared with the control group , the cell proliferation of transfection group was promoted (P < 0. 05) ; The mRNA and protein expression levels of ALP , OPN and OCN in transfection group were significantly lower than those in control group (P < 0. 05) , the expression level of ALP apparently decreased after the addition of mTOR inhibitor rapamycin (P < 0. 05) ; Alizarin red staining showed that the size and number of mineralized nodules formed in transfection group were markedly declined compared with empty carrier group (P < 0. 05) . Conclusion Overexpression of Lin28 can inhibit the osteogenic differentiation of hDP⁃ SCs through suppress mTOR signaling pathway.

Objective:To explore the clinical characteristics, plasma levels of hydrogen sulfide(H 2S) and the relationship between the genotype and phenotype of cardiovascular involvement in children with methylmalonic acidemia and homocystinemia. Methods:The clinical and laboratory data of 66 outpatients diagnosed with methylmalonic acidemia combined with homocystinemia in Department of Pediatrics, Peking University First Hospital from January 2014 to July 2014 were collected and analyzed respectively, and the patients were divided into 2 groups: cardiovascular involvement group (10 cases) and non-cardiovascular involvement group(56 cases). The differences in the clinical characteristics, plasma levels of H 2S and genotypes were compared between 2 groups. Results:(1) There were 45 cases of early-onset children under 1 year old, including 4 cases of cardiovascular system involvement and 41 cases of non-cardiovascular system involvement.Twenty-one cases had onset above 1 year old, including 6 cases of cardiovascular system involvement and 15 cases of non-cardiovascular system involvement. There were 44 male children, including 8 cases with cardiovascular system involvement and 36 cases without cardiovascular system involvement; 22 cases female children, including 2 cases with cardiovascular system involvement and 20 cases without cardiovascular system involvement. There was no significant difference in onset age and gender distribution between the 2 groups ( χ2=2.910, 0.368, all P>0.05). (2)In the 10 cases with cardiovascular involvement, there were 3 cases with hypertension, 2 cases with hypertension combined with pulmonary hypertension, 2 cases with mild myocardial hypertrophy, 1 case with atrial septal defect combined with pulmonary hypertension, 1 case with pulmonary hypertension, 1 case with myocardial noncompaction.Compared with the non-cardiovascular involvement group, the proportion of kidney involvement was increased and that of nervous system was decreased in cardiovascular system involvement group( χ2=20.34, 5.79, all P<0.05), the proportion of hematological system involvement between the 2 groups had no significant differences ( χ2=1.28, P>0.05). The plasma levels of hydrogen sulfide of children with cardiovascular involvement was significantly lower than that of non-cardiovascular involvement[(33.8±3.6) μmol/L vs.(39.3±5.2) μmol/L, t=-3.22, P<0.01]. (3) MMACHC gene mutation (cblC type) was identified in all 46 patients.It was found that the most common type of gene mutation was c. 80A>G in cardiovascular involvement group, while c. 609G>A was the most common type of gene mutation in non-cardiovascular involvement group. Conclusions:The clinical manifestations of children with methylmalonic acidemia and homocystinemia involving cardiovascular system are multiple and prone to multiple system involvement, especially renal involvement.A decrease in plasma hydrogen sulfide levels may be involved in the involvement of its cardiovascular system.The MMACHC gene c. 80A>G mutation is the most common genetic mutation site in children with cardiovascular involvement with methylmalonic acidemia and homocystinemia.
