Objective:To investigate the neuroprotective effect of non-invasive vagus nerve stimulation(nVNS)on traumatic brain injury(TBI).Methods:Male SD rats were used to prepare controlled cortical impact(CCI)rat mod-el.nVNS treatment was performed.The motor function of rats was detected by beam walking test.The water content of rats was evaluated by the dry-wet ratio of rat brain tissue.The content of lactate dehydrogenase(LDH)in cerebrospinal fluid was detected by commercial kit.The expression of bain-derived neurotrophic factor(BDNF)and nerve growth fac-tor(NGF)mRNA in rat cortex was detected by RT-qPCR.Results:After nVNS stimulation,CCI rats significantly im-proved the neurological function deficit,improved the motor ability,decreased the cerebral water content,decreased the level of LDH in cerebrospinal fluid,and upregulated the expression of BDNF and NGF mRNA in cortex.Conclusion:nVNS has a neuroprotective effect on TBI rats,and its mechanism may be related to the increased expression of BDNF and NGF.

Protrusive facial deformities, characterized by the forward displacement of the teeth and/or jaws beyond the normal range, affect a considerable portion of the population. The manifestations and morphological mechanisms of protrusive facial deformities are complex and diverse, requiring orthodontists to possess a high level of theoretical knowledge and practical experience in the relevant orthodontic field. To further optimize the correction of protrusive facial deformities, this consensus proposes that the morphological mechanisms and diagnosis of protrusive facial deformities should be analyzed and judged from multiple dimensions and factors to accurately formulate treatment plans. It emphasizes the use of orthodontic strategies, including jaw growth modification, tooth extraction or non-extraction for anterior teeth retraction, and maxillofacial vertical control. These strategies aim to reduce anterior teeth and lip protrusion, increase chin prominence, harmonize nasolabial and chin-lip relationships, and improve the facial profile of patients with protrusive facial deformities. For severe skeletal protrusive facial deformities, orthodontic-orthognathic combined treatment may be suggested. This consensus summarizes the theoretical knowledge and clinical experience of numerous renowned oral experts nationwide, offering reference strategies for the correction of protrusive facial deformities.

The prevalence of Class III malocclusion varies among different countries and regions. The populations from Southeast Asian countries (Chinese and Malaysian) showed the highest prevalence rate of 15.8%, which can seriously affect oral function, facial appearance, and mental health. As anterior crossbite tends to worsen with growth, early orthodontic treatment can harness growth potential to normalize maxillofacial development or reduce skeletal malformation severity, thereby reducing the difficulty and shortening the treatment cycle of later-stage treatment. This is beneficial for the physical and mental growth of children. Therefore, early orthodontic treatment for Class III malocclusion is particularly important. Determining the optimal timing for early orthodontic treatment requires a comprehensive assessment of clinical manifestations, dental age, and skeletal age, and can lead to better results with less effort. Currently, standardized treatment guidelines for early orthodontic treatment of Class III malocclusion are lacking. This review provides a comprehensive summary of the etiology, clinical manifestations, classification, and early orthodontic techniques for Class III malocclusion, along with systematic discussions on selecting early treatment plans. The purpose of this expert consensus is to standardize clinical practices and improve the treatment outcomes of Class III malocclusion through early orthodontic treatment.

Peri-implant keratinized mucosa (PIKM) augmentation refers to surgical procedures aimed at increasing the width of PIKM. Consensus reports emphasize the necessity of maintaining a minimum width of PIKM to ensure long-term peri-implant health. Currently, several surgical techniques have been validated for their effectiveness in increasing PIKM. However, the selection and application of PIKM augmentation methods may present challenges for dental practitioners due to heterogeneity in surgical techniques, variations in clinical scenarios, and anatomical differences. Therefore, clear guidelines and considerations for PIKM augmentation are needed. This expert consensus focuses on the commonly employed surgical techniques for PIKM augmentation and the factors influencing their selection at second-stage surgery. It aims to establish a standardized framework for assessing, planning, and executing PIKM augmentation procedures, with the goal of offering evidence-based guidance to enhance the predictability and success of PIKM augmentation.

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 role of purine receptor P2X7 in cerebral ischemia-reperfusion injury(CI-RI).Methods:The CIRI model was prepared by right middle cerebral artery occlusion(MCAO).The P2X7 inhibitor bright blue G(BBG)or NLRP3 inhibitor MCC950 were injected intraperitoneally.Neurological function score was used to detect the changes of neural function in rats.The integrity of blood-brain barrier was detected by Evans blue staining.The contents of IL-1 β and IL-18 in cerebrospinal fluid(CSF)of rats were detected by ELISA,and the expressions of P2X7,CD11b,and NLRP3 in the right cerebral cortex were detected by Western Blot.Results:Treatment with BBG or MCC950 improved neural function in CIRI rats,while reducing the amount of Evans blue in brain tissue and IL-1 β and IL-18 levels in CSF.In addition,BBG can reduce the expression of CD11b and NLRP3 in the right cerebral cortex,while MCC950 can only reduce the expression of CD11b,but has no effect on P2X7 expression.Conclusion:BBG alle-viates neuroinflammation in CIRI rats by inhibiting P2X7/NLRP3 pathway.

Objective:To investigate the effect of lateral hydraulic injury(LFPI)on the integrity of blood-brain bar-rier in rats and its molecular mechanism.Methods:The rat LFPI model was prepared.Neurological impairment of rats was assessed by neurological severity score(NSS).The integrity of blood-brain barrier was assessed by dry/wet ratio test and Evans blue penetration test.The expressions of zonula occludens-1(ZO-1),occludin,and aquaporin 4(AQP4)were detected by Western Blot.Results:LFPI resulted in neurological dysfunction,increased cerebral water content,increased Evans blue permeability,decreased occludin and ZO-1 expression,and increased AQP4 expression.Conclusion:LFPI can cause cerebral edema and damage the integrity of blood-brain barrier in rats.

We retrospectively analyzed the clinical data of seven patients (four men and three women) with primary hyperoxaluria (PH) type 1 (PH1) in the Department of Nephrology of Zhongda Hospital, Southeast University from January 2018 to October 2023. The mean age at disease onset was 32.1 (range: 26-42) years. The mean age at diagnosis was 40.6 (range: 28-51) years. All patients initially had kidney stones, and three patients were found to have renal insufficiency at the time of disease onset. Among them, two patients underwent hemodialysis immediately. Symptoms at the first visit included bone pain ( n=7), joint pain or deformity ( n=5), fatigue ( n=5), hypotension ( n=3), and subcutaneous nodules ( n=2). Four patients had a family history of PH. All patients had varying degrees of anemia (60-114 g/L), significant hypoalbuminemia (16.5-32.1 g/L), and hypercoagulable state (D-dimer: 2 230-12 781 μg/L). Seven patients received maintenance hemodialysis; their mean age was 37.7 (range: 26-50) years. The mean duration from disease onset to hemodialysis was 5.6 (range: 0-20) years. Five patients repeatedly experienced dialysis access dysfunction. Three patients underwent kidney transplantation before a diagnosis was made, and all transplanted kidneys lost function due to oxalate deposition. The mean follow-up duration was 14.43 (range: 4-38) months. Unfortunately, one patient died. All seven patients underwent computed tomography of the abdomen. All patients suffered skeletal abnormalities, bilateral nephrolithiasis, and nephrocalcinosis. Six patients carried AGXT gene mutations, including four compound heterozygous mutations and two pure homozygous mutations.The mutation sites included: c.823-824dup.AG (p.S275Rfs*38)(exon 8), c.815-816ins.GA (p.S275Rfs*38)(exon 8), c.595G>A (p.G199S) (exon 5), c.32C>G (p.P11R) (exon 1), and c.638C>T (p.A213V)(exon 6). According to the American College of Medical Genetics and Genomics guidelines, two loci were identified as likely pathogenic variants, seven were identified as pathogenic variants, and one locus was identified as having uncertain significance. In addition, patients 1 and 4 underwent skin biopsy, patient 2 underwent renal transplant biopsy, and patient 3 underwent bone marrow biopsy. Interestingly, significant oxalate deposition was found in the tissues. Therefore, PH1 is a rare autosomal recessive inherited disease. This study not only enhanced the understanding of the clinical characteristics of PH1 patients but also had great significance in early diagnosis and treatment of the disease.
