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 observe the effect of exogenous hydrogen sulfide(H 2S) on the proliferation of rabbit vascular smooth muscle cell(VSMC) under high static pressure. Methods:Rabbit thoracic aorta VSMC were isolated and cultured under high static pressure(100mmHg) and divided into control group [cultured with 0.2%fetal bovine serum(FBS) and no NaHS]、10%FBS group(10%FBS and no NaHS) and NaHS group(10%FBS and 50mmol/L NaHS). VSMC proliferation was analyzed with BUDR. CSE, Calmodulin(p-CaM)and CyclinD1 protein levels of VSMC were measured by Western blotting.Results:Compared with the 10%FBS group, NaHS inhibit the proliferation of rabbit VSMC significantly (0.50±0.03 vs. 0.26±0.03, P<0.05). Compared with control group, CSE protein in the 10%FBS group decreased significantly(1.21±0.10 vs. 0.33±0.04, P<0.05) and p-CaM and CyclinD1 protein increased significantly(0.23±0.04 vs. 0.86±0.04 and 0.22±0.03 vs. 1.19±0.06, P<0.05). Compared with the 10%FBS group, CSE protein in NaHS group increased significantly(0.33±0.04 vs. 1.11±0.11, P<0.05), and the expression of p-CaM and CyclinD1 protein decreased significantly(0.86±0.04 vs. 0.26±0.05 and 1.19±0.06 vs. 0.51±0.03, P<0.05). Conclusion:Exogenous hydrogen sulfide inhibits the proliferation of VSMC under high static pressure by the CSE/H2S pathway which related to the reduction of the expression of p-CaM and CyclinD1.

Objective To establish staff performance evaluation system of academy of medical sciences.Methods The Delphi method was employed.Results The main indicators of staff performance evaluation were selected by two-round of the Delphi method,and the evaluation system was established.Evaluation indicators covered different types of jobs of science research,medical services,disease prevention,medical education,science and technology support.Conclusions After two-round of consultation,there were more consistencies among experts regarding to selection of evaluation indicators.It will be tested and justified by further theoretical and empirical research.

Objectives:To evaluate the use of needle catheter jejunostomy for early enteral nutrition in liver transplant recipients . Methods:Five liver transplant recipients who had indication were performed with needle catheter jejunostomy before abdominal wall closure.The Flocare jejunokath was inserted on the small bowel at the point 20 cm distal to the ligament of Treitz,continued to go ahead in the wall of the bowel for a distance of about 4～5 cm,and then pierced into bowel lumen.Enteral nutrition was given through jejunostic tube at postoperative 1st day. Results:The time for placing needle catheter jejunostomy during operation was (9.2?2.3)min.The jejunostic tube was used well and pulled out from 14 to 46 days after operation.One patient occurred with jejunostic tube obstruction, and the tube was reused after treatment.No other complication occurred associated with needle catheter jejunostomy. Conclusions:Needle catheter jejunostomy may become the preferable method for early enteral nutrition in indicated liver transplant recipients.
