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 application effect of complete decongestive therapy (CDT) and resistance exercise in postoperative breast cancer patients.Methods:A total of 102 breast cancer patients in the Breast Surgery Department of Yantaishan Hospital of Yantai from January 2021 to June 2023 were selected using convenience sampling. Patients were randomly divided into an observation group ( n=52) and a control group ( n=50). In the observation group, 25 patients underwent sentinel lymph node biopsy (SLNB), and 27 underwent axillary lymph node dissection (ALND) ; in the control group, 25 underwent SLNB, and 25 underwent ALND. The control group received routine nursing care, while the observation group received CDT combined with resistance exercise in addition to routine care. The incidence of upper limb lymphedema, axillary web syndrome (AWS), and upper limb functional recovery were compared between the two groups. Results:At 2 weeks postoperatively, the incidence of upper limb lymphedema was significantly lower in the observation group compared to the control group ( P<0.01). At 1 month and 3 months postoperatively, the incidence of AWS in SLNB and ALND patients in the observation group were significantly lower than those in the control group ( P<0.05). At 2 weeks postoperatively, Neer shoulder joint function scores in SLNB and ALND patients in the observation group were significantly higher than those in the control group ( P<0.01) . Conclusions:CDT combined with resistance exercise reduces the incidence of upper limb lymphedema and AWS, while promoting shoulder joint functional recovery in postoperative breast cancer patients. It is worthy of clinical application.

Objective:To investigate the clinical value of ultrasound in evaluating pharyngeal dysphagia after stroke.Methods:Thirty stroke survivors with dysphagia formed the patient group, and 30 healthy persons formed the healthy group. All received pharyngeal ultrasound examinations by the same sonographer. The maximum distance from the hyoid bone to the mandible, the minimum distance, and the required time were measured or calculated. The hyoid bone′s motion, distance shortening rate, geniohyoid muscle activity, activity time, and activity speed were calculated. The differences in each value were compared, and the values were correlated with the videofluoroscopic swallowing study (VFSS) score using Spearman rank correlation. Receiver operating characteristics curves (ROC curves) were used to evaluate the value of hyoid bone and geniohyoid muscle activity for evaluating the severity of pharyngeal swallowing disorders after a stroke.Results:The average range of activity, activity time, and activity speed of the geniohyoid muscle in the patient group were all significantly different from the healthy group′s averages. The hyoid bone′s range of activity, activity time, activity speed, and the rate of shortening of its distance from the mandible were also significantly different, on average. The patients′ VFSS grades correlated strongly with the activity of the geniohyoid muscle, moderately with the geniohyoid muscle′s speed, and weakly with the duration of hyoid bone activity.Conclusion:The speed of geniohyoid muscle activity and hyoid bone activity time can be used to evaluate the severity of pharyngeal swallowing dysfunction after a stroke. Geniohyoid muscle activity is the best indicator.

Objective To explore the relationship between the expression levels of serum cingulate protein(CGN)and polyligand glycan 1(SDC-1)and the disease condition and outcome of hypertensive basal ganglia hemorrhage(HBGH).Methods A total of 123 patients with HBGH admitted to the Second People's Hospi-tal of Lianyungang from February 2019 to February 2022 were selected as the study objects,and 120 healthy volunteers who underwent physical examination in the hospital during the same period were selected as the health group.Serum CGN and SDC-1 expression levels were detected in the two groups.According to the dis-ease outcome,the patients were divided into the improved group(92 cases)and the deteriorated group(31 ca-ses).Receiver operating characteristic(ROC)curve and the area under the curve(AUC)were used to analyze the predictive value of serum CGN and SDC-1 expression levels on the disease outcome of patients with HB-GH.Results Serum CGN and SDC-1 expression levels in the severe group were higher than those in the mod-erate group and the mild group,and serum CGN and SDC-1 levels in the moderate group were higher than those in the mild group,and the differences were statistically significant(P＜0.05).Serum CGN and SDC-1 expression levels in HBGH patients in three groups were higher than those in health group,and the differences were statistically significant(P＜0.05).Serum CGN and SDC-1 expression levels in the deteriorated group were higher than those in the improved group,and the differences were statistically significant(P＜0.05).The AUC of serum CGN and SDC-1 for predicting the disease outcome of HBGH patients was 0.742(95％CI:0.792-0.697)and 0.861(95％CI:0.906-0.910),respectively,and the AUC of the combination of the two was 0.917(95％CI:0.962-0.870).The amount of blood loss and ventricular rupture in the deteriorated group were higher than those in the improved group,and the Glasgow Coma Scale(GCS)score on admission was lower than that in the improved group,and the differences were statistically significant(P＜0.05).Multi-variate Logistic regression analysis showed that serum CGN≥51.63 pg/mL(OR=3.815),serum SDC-1≥450.67 μg/L(OR=4.230)and GCS score ≤8(OR=5.333)were the influencing factors for disease outcome of HBGH patients(P＜0.05).Conclusion The increased expression levels of serum CGN and SDC-1 are closely related to the disease aggravation and the deterioration of the disease outcome in patients with HBGH,and they have certain predictive value for the disease outcome in patients with HBGH.

Objective To investigate the clinicopathological characteristics of extranodal NK/T cell lymphoma(ENKTL)with B-lymphocytosis.Methods Two cases of ENKTL with B-lymphocytosis diagnosed in Shaanxi Provincial People's Hospital from June to September 2023 were collected.HE staining,immunohistochemistry,and in situ hybridisation Epstein-barr virus encoded small RNA(EBER)testing was used to observe the histological features,immunophenotypes,and results of the in situ hybridisation EBER testing.A review of the relevant literature was conducted.Results In two cases of elderly male patients,whose lesion sites were on both the right side of the nasal cavity,histological characteristics of the tumor cells were diffuse distribution.The cells were of different sizes,mainly medium and large cells,with irregular nuclei,stained or transparent cytoplasm,oval nuclei,granular chromatin and inconspicuous nucleoli.Nuclear schizophrenia was more common and coagulative necrosis and apoptosis were evident.Foci of small lymphocyte aggregates were seen in the background and lymphoid follicles were distributed in a scattered manner.Immunohistochemical CD2,CD3,CD56,TIA-1 and granzyme B(GrB)were positive.CD20,CD79a and PAX-5 were focal positive.CD21,CD23 and CD35 had residual FDC network,and CD5 was negative.Ki-67 proliferation index was approximately 30%.EBER tumor cells detected by in situ hybridisation were positive.Pathological diagnosis showed ENKTL with B-lymphocytosis.Conclusion NKTL with B-lymphocytosis was rare,especially when B-lymphocyte hyperplasia formed lymphoid follicles.Lack of experience can easily cause diagnostic difficulties,and comprehensive analysis and diagnosis should be combined with the clinical manifestations,histological morphology and immunophenotype.

Objective:To demonstrate the three-dimensional structures of the limbic system and its fiber connections through fiber dissection,and to provide reference for relevant professionals to master the anatomy of the limbic system.Methods:Ten cerebral hemispheres were treated and dissected according to Kelinger method,and the limbic system and its fiber connections were displayed.Results:The limbic system was arranged around the thalamus and corpus cal-losum in a double-layer concentric circle structure.The outer layer structures mainly consisted of the cingulate gyrus and the parahippocampal gyrus,while the inner layer structures included the amygdala,hippocampus and fornix.The main association fiber of the outer layer is the cingulum,whose superior trunk is mainly located in the cingulate gyrus,and the inferior trunk is mainly located in the parahippocampal gyrus.The fiber structures of the inner layer includes the striae terminalis and ansa peduncularis emanating from the amygdala and the fornix of the hippocampus.Conclusion:Limbic system is an important connection structure between telencephalon and diencephalon,and its anatomical struc-ture is complex.Fiber dissection method can effectively demonstrate the complex spatial structure of limbic system,which is of great benefit to relevant professionals to understand its three-dimensional structure.

Objective:To evaluate the feasibility, accuracy, effectiveness and safety of a novel manual placement of cervical 7 pedicle screws via the posterior approach of cervicothoracic junction.Methods:A retrospective case series study was conducted to analyze the 35 patients with injury to the lower cervical spine or cervicothoracic junction who had been treated by a novel manual placement of cervical 7 pedicle screws at Department of Orthopedics, The First Affiliated Hospital of Zhengzhou University from March 2015 to July 2021. There were 16 males and 19 females, with an age of (52.7±13.2) years. The core of this placement was to determine the entry point of cervical 7 pedicle screws. After the intersection of the upper edge of the cervical 7 lamina and the medial edge of the superior articular process was recorded as point A while the intersection of the lateral edge of the inferior articular process and the lower edge of the transverse process as point B, the intersection of the outer and middle 1/3 of the AB line was taken as the screw entry point, with the screw placement angle perpendicular to the lamina line or slightly inclined from 30° to 40° to the head side and outward. The length, diameter and placement angle of the cervical 7 pedicle screws were recorded and compared postoperatively between the left and right sides to explore the feasibility of this novel manual placement. According to the Rampersaud method, the screw positions were graded 1 week and 6 months after operation to evaluate the accuracy of this manual placement. The visual analogue scale (VAS) and the Japanese Orthopaedic Association (JOA) score were compared between preoperation, 1 week and 6 months after operation to evaluate the effectiveness of this placement. The postoperative complications were counted to evaluate the safety of this method. Loosening, displacement and breakage of the screws were observed by CT scanning at 6 months after operation.Results:This case series was followed up for (9.8±1.7) months. There was no significant difference in the length, diameter or placement angle of the screws between the left and right sides ( P>0.05). A total of 66 cervical 7 pedicle screws were placed. There was no change in the screw position grading at 1 week or 6 months after surgery. Grade A was achieved in 64 screws, Grade B in 2 screws, and Grade C or D in none. The VAS scores before operation, 1 week and 6 months after operation were respectively 4.4±1.7, 3.8±1.0 and 1.1±1.1, and the JOA scores respectively 6.7±2.2, 13.2±1.5 and 15.3±1.2. The VAS and JOA scores at 1 week and 6 months after operation were significantly improved compared with the preoperative values ( P<0.05). The improvement rates in JOA at 1 week and 6 months after operation were 62.7%±13.3 % and 83.9%±11.6%, respectively. There were no complications related to the placement of cervical 7 pedicle screws; there was no wound hematoma or infection. No loosening, displacement or breakage of the screws was observed by the 6-month follow-up. Conclusion:The novel manual placement of cervical 7 pedicle screws via the posterior approach of cervicothoracic junction is feasible, accurate, effective and safe.
