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.

Background and Aims:With the widespread use of electrosurgical devices in open thyroid surgery,the surgical smoke generated during procedures has become a significant concern,as it compromises surgical visibility,reduces operational efficiency,and poses health risks to medical staff.Currently,local smoke evacuation is commonly performed by an assistant using a handheld suction device,which is limited in range,interferes with surgical procedures,and increases labor costs.This study aimed to evaluate the effectiveness,safety,feasibility,and staff satisfaction associated with a self-made annular smoke evacuation device constructed from readily available materials for use in open thyroid surgery.Methods:A total of 82 patients undergoing open surgery for papillary thyroid carcinoma at Suqian First People's Hospital between March and June 2024 were randomly assigned to an observation group and a control group(41 patients each).During surgery,the observation group used a self-made annular smoke evacuation device for continuous smoke removal,while the control group used conventional manual suction via an assistant.Outcomes compared between the two groups included PM2.5 concentrations 30 cm above the surgical field,operative time,intraoperative blood loss,and medical staff satisfaction with smoke removal.Results:During thyroid tissue dissection,the PM2.5 concentration in the observation group was(63.26±11.71)μg/m3,corresponding to a"good"air quality level,while in the control group it was(126.35±40.12)μg/m3,ranging from"mild to severe pollution"—a statistically significant difference(P<0.05).In the observation group,operative times for unilateral and bilateral procedures were(31.25±11.36)min and(71.13±17.12)min,respectively,with intraoperative blood loss of(10.5±5.3)mL and(18.6±5.5)mL.In the control group,times were(39.27±15.42)min and(78.35±22.35)min,with blood loss of(12.5±5.8)mL and(20.5±6.5)mL,respectively—all differences not statistically significant(all P>0.05).Staff satisfaction was significantly higher in the observation group compared to the control group(97.6%vs.31.7%,P<0.05).Conclusion:The self-made annular smoke evacuation device demonstrated favorable results in open thyroid surgery,effectively reducing surgical smoke concentration,improving visibility,and minimizing health risks to medical staff without compromising surgical efficiency or safety.The device is cost-effective,easy to assemble,and can be repurposed postoperatively as a drainage tube,requiring no additional consumables.Its reusability and ease of integration offer strong practical value and clinical applicability.

By sorting out the differences and connections between family doctor teams and specialized disease teams, role competency and mutual collaboration, and introducing the learning health system (LHS) mechanism, a comprehensive operating system for community general practice learning organizations based on LHS was constructed, focusing on five single disease types. The system includes a combination of general and specialized medicine that links three levels of medical institutions, thereby opening up the business cooperation process between professionals in different institutions, and establishing a sustainable collaboration mechanism. This allows medical institutions at three levels to continuously tap the potential of their disciplines, achieve their own ability growth and feel higher work value, and also bring better health solutions to residents, guided by the common goal of "health centered, patient centered".

BACKGROUND:As a dominant breed pig in southwest China,the southern Yunnan small-ear pig has been widely used as an experimental animal in the basic research of other disciplines,but there are still no reports on its application in anterior cruciate ligament reconstruction. OBJECTIVE:To establish a large animal model of the southern Yunnan small-ear pig with anterior cruciate ligament with autologous Achilles tendon was established. METHODS:Twenty adult female Yunnan small-ear pigs were equally randomized into two groups.In the autologous Achilles tendon group,the right knee anterior cruciate ligament was reconstructed with autologous Achilles tendon as a graft,while in the sham-operated group,a similar operation was performed on the right knee without any treatment of the anterior cruciate ligament.General conditions of each pig were observed and recorded before and 12 months after surgery.Ligaments and grafts were taken for gross observation and MAS scoring.Hematoxylin-eosin staining was performed to observe morphological characteristics of ligaments.The staining and arrangement of type I and type Ⅲ collagen were evaluated by immunohistochemistry.Transmission electron microscopy was used to observe the type,size,diameter,ratio,and distribution of collagen fibers in ligaments. RESULTS AND CONCLUSION:All animals had normal diet and activity,good wound healing,no obvious inflammatory reaction,no local purulent infection,and no significant changes in mental and urinary conditions compared with those before surgery.The reconstructed cruciate ligament of the knee was intact,with no stiffness and normal range of motion.Both the anterior drawer and Lachman tests were negative.Gross observation of the graft:12 months after surgery,the grafts was in good position,with good integrity,obvious tension,ligament color close to the original anterior cruciate ligament,and complete surface synovial coverage.Most of the intraarticular ligaments in the autologous Achilles tendon group were defined as MAS I type and a few were defined as MAS Ⅱ type.In the sham-operated group,the intraarticular ligament was defined as MAS I type.Hematoxylin-eosin staining indicated that,12 months after surgery,collagen fibers in the autologous Achilles tendon group began to appear bundled,isotropic,and uniformly arranged,with more obvious isotropic corrugations,and the nuclei were mainly linear or spindle-shaped,which were similar to those in normal anterior cruciate ligament tissue of the sham-operated group.Immunohistochemistry results indicated that,12 months after surgery,there was a higher expression of type I collagen and significantly less expression of type Ⅲ collagen in the reconstructed anterior cruciate ligament in the autologous Achilles tendon group.The degree of type I and type Ⅲ staining was similar in the two groups.Under the transmission electron microscope,the diameter,arrangement and density of collagen fibers in the reconstructed anterior cruciate ligament of the autologous Achilles tendon group were similar to those of the original anterior cruciate ligament at 12 months after surgery,indicating that the ligament remodeling process had been basically completed in the autologous Achilles tendon group at 12 months after surgery.Through a comprehensive evaluation of animal general conditions,ligament general view,MAS score,hematoxylin-eosin staining,immunohistochemistry,and transmission electron microscopy observation,we successfully established a large animal model of anterior cruciate ligament reconstruction using autogenous Achilles tendon in southern Yunnan small-ear pigs,with good morphological,histological and ultrastructural results.

Objective:To investigate the effect of clozapine on endocrine hormone levels in patients with schizophrenia, and to analyze the factors causing metabolic abnormality.Methods:The clinical data of 102 patients with schizophrenia who received treatment at the Wenzhou Seventh People's Hospital from January 2021 to January 2023 were retrospectively analyzed. All patients were treated with clozapine. They were divided into a normal metabolism group ( n = 76) and a metabolic abnormality group ( n = 26) according to whether or not metabolic abnormality occurred after treatment. The glycolipid metabolism levels, thyroid function, and gonadal hormone levels were recorded and compared between the two groups. Logistic regression analysis was then performed to determine the relevant factors influencing the occurrence of concurrent metabolic abnormality in these patients. Results:After treatment, the levels of triglyceride, low-density lipoprotein, glycosylated hemoglobin, triiodothyronine, and prolactin in patients were all significantly increased compared with those measured before treatment, while estradiol level was significantly decreased compared with that measured before treatment ( t = 2.84, 3.36, 25.35, 3.26, 4.88, -5.76, all P < 0.05). Body mass index, disease duration, and the levels of triglyceride, glycosylated hemoglobin, triiodothyronine, and prolactin in the metabolic abnormality group were significantly higher than those in the normal metabolism group, while the levels of low-density lipoprotein, FT 4, and estradiol in the metabolic abnormality group were significantly lower than those in the normal metabolism group ( t = 4.41, 5.67, 3.20, 4.71, 3.49, 3.97, -4.84, -4.51, -4.25, all P < 0.05). The results of the logistic regression analysis indicated that high body mass index ( OR = 7.410, 95% CI = 1.485-36.988), prolonged disease duration ( OR = 1.385, 95% CI = 1.088-1.764), low low-density lipoprotein level ( OR = 0.003, 95% CI = 0.000-0.453), elevated glycosylated hemoglobin level ( OR = 4.222, 95% CI = 1.067-16.706), decreased FT 4 level ( OR = 0.238, 95% CI = 0.086-0.655), and low estradiol level ( OR = 0.845, 95% CI = 0.726-0.984) were the factors associated with metabolic abnormality (all P < 0.05). Conclusion:The use of clozapine in the treatment of schizophrenia will affect the patient's glycolipid metabolism, thyroid function, and gonadal hormone levels. At the same time, it is found that high body mass index, long disease duration, low low-density lipoprotein level, high glycosylated hemoglobin level, low FT 4 level, and low estradiol level will increase the risk of metabolic abnormality in patients. Therefore, targeted interventions should be carried out according to the actual situation.

Pulmonary blast injury has become the main type of trauma in modern warfare, characterized by externally mild injuries but internally severe injuries, rapid disease progression, and a high rate of early death. The injury is complicated in clinical practice, often with multiple and compound injuries. Currently, there is a lack of effective protective materials, accurate injury detection instrument and portable monitoring and transportation equipment, standardized clinical treatment guidelines in various medical centers, and evidence-based guidelines at home and abroad, resulting in a high mortality in clinlcal practice. Therefore, the Trauma Branch of Chinese Medical Association and the Editorial Committee of Chinese Journal of Trauma organized military and civilian experts in related fields such as thoracic surgery and traumatic surgery to jointly develop the Clinical treatment guideline for pulmonary blast injury ( version 2023) by combining evidence for effectiveness and clinical first-line treatment experience. This guideline provided 16 recommended opinions surrounding definition, characteristics, pre-hospital diagnosis and treatment, and in-hospital treatment of pulmonary blast injury, hoping to provide a basis for the clinical treatment in hospitals at different levels.

Objective:To explore any changes with age in the center of plantar pressure among normal people after walking.Methods:Fifty healthy subjects were divided into a young group and an elderly group, each of 25. Gait descriptors were collected for each subject using a model AL-600 gait and balance training and evaluation apparatus. The gait descriptors were the center of pressure displacement (COPD), and the COPD in the medial-lateral (COPD-X) and anterior-posterior (COPD-Y) directions before and after 10 and 15 minutes of walking.Results:The average COPD, COPD-X and COPD-Y of the elderly group increased after both 10 and 15 minutes of walking, but among the young group increases were observed only after 15 minutes. The average COPD, COPD-X and COPD-Y of the elderly group were always significantly larger than the young group′s averages.Conclusions:Gait stability among the elderly decreases after as little as 10 minutes of walking, but among the young decreases are observed only after 15 minutes.

Objective:To explore the value of contrast-enhanced ultrasound (CEUS) combined with Ovarian-Adnexal Reporting and Data System (O-RADS US) risk stratification and management system in differential diagnosis of ovarian-adnexal mass.Methods:Fifty-six patients with ovarian-adnexal mass who received transabdominal transvaginal ultrasound and CEUS in the Third People′s Hospital of Longgang District from September 2018 to January 2021 were enrolled. The images were classified by O-RADS US and diagnosed by CEUS by experienced and senior radiologist. On the basis of O-RADS US classification, the enhancement time, enhancement level and enhancement mode of CEUS were combined to upgrade or degrade the classification results of O-RADS US. The diagnostic accuracy was assessed using ROC curve analysis, the area under the ROC curve (AUC) was calculated. The reproducibility of O-RADS US was assessed by another senior radiologist.Results:The AUC of O-RADS US for diagnosing benign and malignant ovarian-adnexal masses was 0.844(0.722, 0.927), the AUC of CEUS was 0.833(0.710, 0.920), the AUC of O-RADS US combined with CEUS was 0.940(0.842, 0.986) (compared with O-RADS US, P=0.020; compared with CEUS, P=0.031). The intra-class correlation coefficient (ICC) was 0.897(0.824, 0.940) for O-RADS US. Conclusions:CEUS combined with O-RADS US classification can effectively improve the diagnostic efficiency for benign and malignant ovarian-adnexal masses.
