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 investigate the effect and mechanism of Grifola frondosa extract on inflammatory response of colon tissue in rats with ulcerative colitis(UC)by regulating interleukin-6(IL-6)/Janus kinase 2(JAK2)/signal transducer and activator of transcription 3(STAT3)signaling pathway.Methods:Forty SD rats were randomly divided into blank control group,UC model group,Grifola frondosa treatment group,western medicine treatment group and combined treatment group,with 8 rats in each group.After UC rats were established by free drinking 3%DSS for 7 days,the treatment group were given Grifola frondosa extract 10 mg/(kg·d),sulfasalazine 0.3 g/(kg·d),and the same amount of two drugs,for 14 consecutive days.During the experiment,general state of rats were observed,and the disease activity index(DAI)score was calculated;pathological changes of rats colon tissue were observed by HE staining;protein expression levels of IL-6,JAK2,STAT3 and p-STAT3 in rats colon tissue were detected by Western blot;content of IL-6 in rats serum was detected by ELISA;protein contents and expressions of IL-6R and MPO in rats colon tissue were determined by immunohistochemistry.Results:Compared with blank control group,general state of rats in UC model group was poor,DAI score was increased,obvious tissue mucosal defects and inflammatory cell infiltration were observed by HE staining;protein expression levels of IL-6,JAK2,STAT3 and p-STAT3 in rats colon tissue and contents of IL-6R and MPO were significantly increased(P<0.01);content of IL-6 in rats serum was significantly increased(P<0.01),the difference was statistically significant.Compared with UC model group,general condition of rats in each treatment group was improved,DAI score was decreased,HE staining showed that mucosal defects were improved to varying degrees,and occasionally inflammatory cell infiltration was observed;protein expression levels of IL-6,JAK2,STAT3 and p-STAT3 in colon tissue were significantly decreased(P<0.01),contents of IL-6R and MPO in colon tissue and content of IL-6 in serum were significantly decreased(P<0.01 or P<0.05),the differences were statistically significant.Conclusion:Grifola frondosa extract can reduce the inflammatory response in colon tissue of UC rats by regulating expressions of IL-6/JAK2/STAT3 signaling pathway related factors.

Objective:To investigate the safety and efficacy of total pelvic exenteration (TPE) for treating late complications of radiation-induced pelvic injury.Methods:This was a descriptive case series study. The inclusion criteria were as follows: (1) confirmed radiation-induced pelvic injury after radiotherapy for pelvic malignancies; (2) late complications of radiation-induced pelvic injury, such as bleeding, perforation, fistula, and obstruction, involving multiple pelvic organs; (3) TPE recommended by a multidisciplinary team; (4) patient in good preoperative condition and considered fit enough to tolerate TPE; and (5) patient extremely willing to undergo the procedure and accept the associated risks. The exclusion criteria were as follows: (1) preoperative or intraoperative diagnosis of tumor recurrence or metastasis; (2) had only undergone diversion or bypass surgery after laparoscopic exploration; and (3) incomplete medical records. Clinical and follow-up data of patients who had undergone TPE for late complications of radiation-induced pelvic injury between March 2020 and September 2022 at the Sixth Affiliated Hospital of Sun Yat-sen University were analyzed. Perioperative recovery, postoperative complications, perioperative deaths, and quality of life 1 year postoperatively were recorded.Results:The study cohort comprised 14 women, nine of whom had recto-vagino-vesical fistulas, two vesicovaginal fistulas, one ileo-vesical fistula and rectal necrosis, one ileo-vesical and rectovaginal fistulas, and one rectal ulcer and bilateral ureteral stenosis. The mean duration of surgery was 592.1±167.6 minutes and the median blood loss 550 (100–6000) mL. Ten patients underwent intestinal reconstruction, and four the Hartmann procedure. Ten patients underwent urinary reconstruction using Bricker's procedure and 7 underwent pelvic floor reconstruction. The mean postoperative hospital stay was 23.6±14.9 days. Seven patients (7/14) had serious postoperative complications (Clavien-Dindo IIIa to IVb), including surgical site infections in eight, abdominopelvic abscesses in five, pulmonary infections in five, intestinal obstruction in four, and urinary leakage in two. Empty pelvis syndrome (EPS) was diagnosed in five patients, none of whom had undergone pelvic floor reconstruction. Five of the seven patients who had not undergone pelvic floor reconstruction developed EPS, compared with none of those who had undergone pelvic floor reconstruction. One patient with EPS underwent reoperation because of a pelvic abscess, pelvic hemorrhage, and intestinal obstruction. There were no perioperative deaths. During 18.9±10.1 months of follow-up, three patients died, two of renal failure, which was a preoperative comorbidity, and one of COVID-19. The remaining patients had gradual and significant relief of symptoms during follow-up. QLQ-C30 assessment of postoperative quality of life showed gradual improvement in all functional domains and general health at 1, 3, and 6 months postoperatively (all P<0.05). Conclusions:TPE is a feasible procedure for treating late complications of radiation-induced pelvic injury combined with complex pelvic fistulas. TPE is effective in alleviating symptoms and improving quality of life. However, the indications for this procedure should be strictly controlled and the surgery carried out only by experienced surgeons.

Copy number variations (CNVs), which can affect the role of long non-coding RNAs (lncRNAs), are important genetic changes seen in some malignant tumors. We analyzed lncRNAs with CNV to explore the relationship between lncRNAs and prognosis in bladder cancer (BLCA). Messenger RNA (mRNA) expression levels, DNA methylation, and DNA copy number data of 408 BLCA patients were subjected to integrative bioinformatics analysis. Cluster analysis was performed to obtain different subtypes and differently expressed lncRNAs and coding genes. Weighted gene co-expression network analysis (WGCNA) was performed to identify the co-expression gene and lncRNA modules. CNV-associated lncRNA data and their influence on cancer prognosis were assessed with Kaplan-Meier survival curve. Multi-omics integration analysis revealed five prognostic lncRNAs with CNV, namely

[Abstrict]Objective To explore the key points and clinical value of combined direct and indirect extracranial-in?tracranial (EC-IC) bypass in patients with adult moyamoya disease. Methods Retrospective analysis of combined revas?cularization surgery in 25 adult patients with moyamoya disease. The frontal branch and parietal branch of the superficial temporal artery (STA) were dissected. Combined revascularization surgery consisted of direct (anastomosis between the su?perficial temporal artery and cortical branch of the middle cerebral artery) and indirect (encephalodurogaleosynan-giosis EDAS) surgeries. Clinical status was evaluated using the modified Rankin Scale and NIHSS score at 1 day before, 1 week and 3 months after surgery. Results Thirty lateralities were successfully performed on 25 patients. Postoperative angiogra?phy or CTA and cranial computer tomography perfusion imaging(CTP) were conducted to examine the patency of the di?rect anastomosis and cerebral blood flow in 23 patientswithin 1 weeks after surgery . The results showed that the anasto?motic vascular patency was excellent and the cerebral blood flow increased in parallel to the relief of the patients’s isch?emic symptoms. The median mRS scores were 3 (1,3) before surgery, 2 (1,3) 1 week and 1 (0,3) 1 month after surgery.The median mRS scores were significantly improved (Z=15.14, P<0.01). The median NIHSS scores was 5 (4,8) preopera?tively and 4(2,7) postoperation 1 week and 3(1,4) 3 months. The median NIHSS scores were also significantly improved (Z=11.36, P<0.01). Unfortunately, two patients had complication and left hemiparesis. One patient complicated with con?tralateral hemisphere infarction and the another one complicated with ipsilateral hemispheric hemorrhage after operation. Conclusions Combined revascularization surgery may result in satisfying improvement in clinical, angiographic, and he?modynamic states and prevention of recurrent stroke. The stabilized hemodynamic is the key point in peroperative period for moyamoya patients.

Objective To study the effect of long-time carbon dioxide (CO2) pneumoperitoneum on QT dispersion (QTd) in elderly patients during Davinci robotassisted surgery.Methods Thirty elderly patients undergoing elective Davinci robot-assisted hepato-pancreato-biliary surgery with general anesthesia were enrolled in this study.Pneumoperitoneum was established at 12 mm Hg ( 1 mm Hg =0.13 3 k Pa).QTd was recorded before the induction of anesthesia; at 5,15,30,60,120,180 and 240 min after pneumoperitoneum.Results Compared with before anesthesia,mean arterial blood pressure (MAP) increased significantly at 15,30 min after pneumoperitoneum ( P＜0.05 ),and had no significant difference at 5,60,120,180,240min (P＞0.05 ).Heart rate (HR) increased significantly at 15,30 min after pneumoperitoneum (P＜0.05 ).End-tidal pressure of carbon dioxide (PETCO2) increased after pneumoperi-toneum,and had significant difference at 30,60,120,180,240 min after pneumoperitoneum (P＜0.05).In 30 patients,11 patients occurred arrhythmia including atrial extrasystole,premature ventricular beats,tachycardia.Compared with before anesthesia,QTd,corrected QTd (QTcd),QT interval,corrected QT interval (QTe) were significantly increased at 15,30,60 min after pneumoperitoneum (P＜0.05),but had on significant difference at 5,120,180,240 min after pneumoperitoneum (P＞0.05).Conclusion The effect of CO2 pneumoperitoneum on the autonomic nervous system for elderly patients might be important,as an imbalance in autonomic cardiac control might lead to serious consequences.
