Patients with periodontal disease often require combined periodontal-orthodontic interventions to restore periodontal health, function, and aesthetics, ensuring both patient satisfaction and long-term stability. Managing these patients involving orthodontic tooth movement can be particularly challenging due to compromised periodontal soft and hard tissues, especially in severe cases. Therefore, close collaboration between orthodontists and periodontists for comprehensive diagnosis and sequential treatment, along with diligent patient compliance throughout the entire process, is crucial for achieving favorable treatment outcomes. Moreover, long-term orthodontic retention and periodontal follow-up are essential to sustain treatment success. This expert consensus, informed by the latest clinical research and practical experience, addresses clinical considerations for orthodontic treatment of periodontal patients, delineating indications, objectives, procedures, and principles with the aim of providing clear and practical guidance for clinical practitioners.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

With the growing emphasis on maternal and child oral health, the significance of managing oral health across preconception, pregnancy, and infancy stages has become increasingly apparent. Oral health challenges extend beyond affecting maternal well-being, exerting profound influences on fetal and neonatal oral development as well as immune system maturation. This expert consensus paper, developed using a modified Delphi method, reviews current research and provides recommendations on maternal and child oral health management. It underscores the critical role of comprehensive oral assessments prior to conception, diligent oral health management throughout pregnancy, and meticulous oral hygiene practices during infancy. Effective strategies should be seamlessly integrated across the life course, encompassing preconception oral assessments, systematic dental care during pregnancy, and routine infant oral hygiene. Collaborative efforts among pediatric dentists, maternal and child health workers, and obstetricians are crucial to improving outcomes and fostering clinical research, contributing to evidence-based health management strategies.

Recent clinical studies have shown that mutation of phosphatase and tensin homolog deleted on chromosome 10 (PTEN) gene in cancer cells may be associated with immunosuppressive tumor microenvironment (TME) and poor response to immune checkpoint blockade (ICB) therapy. Therefore, efficiently restoring PTEN gene expression in cancer cells is critical to improving the responding rate to ICB therapy. Here, we screened an adeno-associated virus (AAV) capsid for efficient PTEN gene delivery into B16F10 tumor cells. We demonstrated that intratumorally injected AAV6-PTEN successfully restored the tumor cell PTEN gene expression and effectively inhibited tumor progression by inducing tumor cell immunogenic cell death (ICD) and increasing immune cell infiltration. Moreover, we developed an anti-PD-1 loaded phospholipid-based phase separation gel (PPSG), which formed an in situ depot and sustainably release anti-PD-1 drugs within 42 days in vivo. In order to effectively inhibit the recurrence of melanoma, we further applied a triple therapy based on AAV6-PTEN, PPSG^@anti-PD-1 and CpG, and showed that this triple therapy strategy enhanced the synergistic antitumor immune effect and also induced robust immune memory, which completely rejected tumor recurrence. We anticipate that this triple therapy could be used as a new tumor combination therapy with stronger immune activation capacity and tumor inhibition efficacy.

Odontogenic maxillary sinusitis(OMS)is a subtype of maxillary sinusitis(MS).It is actually inflammation of the maxillary sinus that secondary to adjacent infectious maxillary dental lesion.Due to the lack of unique clinical features,OMS is difficult to distinguish from other types of rhinosinusitis.Besides,the characteristic infectious pathogeny of OMS makes it is resistant to conventional therapies of rhinosinusitis.Its current diagnosis and treatment are thus facing great difficulties.The multi-disciplinary cooperation between otolaryngologists and dentists is absolutely urgent to settle these questions and to acquire standardized diagnostic and treatment regimen for OMS.However,this disease has actually received little attention and has been underrepresented by relatively low publication volume and quality.Based on systematically reviewed literature and practical experiences of expert members,our consensus focuses on characteristics,symptoms,classification and diagnosis of OMS,and further put forward multi-disciplinary treatment decisions for OMS,as well as the common treatment complications and relative managements.This consensus aims to increase attention to OMS,and optimize the clinical diagnosis and decision-making of OMS,which finally provides evidence-based options for OMS clinical management.

Endo-periodontal lesions(EPLs)involve both the periodontium and pulp tissue and have complicated etiologies and pathogenic mechanisms,including unique anatomical and microbiological characteristics and multiple contributing factors.This etiological complexity leads to difficulties in determining patient prognosis,posing great challenges in clinical practice.Furthermore,EPL-affected teeth require multidisciplinary therapy,including periodontal therapy,endodontic therapy and others,but there is still much debate about the appropriate timing of periodontal therapy and root canal therapy.By compiling the most recent findings on the etiology,pathogenesis,clinical characteristics,diagnosis,therapy,and prognosis of EPL-affected teeth,this consensus sought to support clinicians in making the best possible treatment decisions based on both biological and clinical evidence.

Due to the insufficient long-term protection and significant efficacy reduction to new variants of current COVID-19 vaccines, the epidemic prevention and control are still challenging. Here, we employ a capsid and antigen structure engineering (CASE) strategy to manufacture an adeno-associated viral serotype 6-based vaccine (S663V-RBD), which expresses trimeric receptor binding domain (RBD) of spike protein fused with a biological adjuvant RS09. Impressively, the engineered S663V-RBD could rapidly induce a satisfactory RBD-specific IgG titer within 2 weeks and maintain the titer for more than 4 months. Compared to the licensed BBIBP-CorV (Sinopharm, China), a single-dose S663V-RBD induced more endurable and robust immune responses in mice and elicited superior neutralizing antibodies against three typical SARS-CoV-2 pseudoviruses including wild type, C.37 (Lambda) and B.1.617.2 (Delta). More interestingly, the intramuscular injection of S663V-RBD could overcome pre-existing immunity against the capsid. Given its effectiveness, the CASE-based S663V-RBD may provide a new solution for the current and next pandemic.

This paper compared the differences between two kinds of Bufonis Venenum produced by Bufo gargarizans gargarizans and B. gararizans andrewsi, and verified the rationality of the market value orientation of Bufonis Venenum based on the zebrafish mo-del. Twenty batches of Bufonis Venenum from Jiangsu province, Hebei province, Liaoning province, Jilin province, and Liangshan, Sichuan province, including B. gargarizans gargarizans and B. gararizans andrewsi, were collected. The UHPLC-LTQ-Orbitrap-MS combined with principal component analysis was used to compare the differences between two kinds of Bufonis Venenum. According to the limiting conditions of VIP>1, FC<0.5 or FC>2.0, and peak total area ratio>1%, 9 differential markers were determined, which were cinobufagin, cinobufotalin, arenobufagin, resibufogenin, scillaredin A, resibufagin, 3-(N-suberoylargininyl)-arenobufagin, 3-(N-suberoylargininyl)-marinobufagin, and 3-(N-suberoylargininyl)-resibufogenin. The content of 20 batches of Bufonis Venenum was determined according to the Chinese Pharmacopoeia(2020 edition) by high-performance liquid chromatography, and the 2 batches of Bufonis Venenum, CS7(8.99% of total content) and CS9(5.03% of total content), with the largest difference in the total content of the three quality control indexes of the Chinese Pharmacopoeia(bufalin, cinobufagin, and resibufogenin) were selected to evaluate their anti-liver tumor activity based on the zebrafish model. The tumor inhibition rates of the 2 batches were 38.06% and 45.29%, respectively, proving that only using the quality control indexes of the Chinese Pharmacopoeia as the value orientation of Bufonis Venenum market circulation was unreasonable. This research provides data support for the effective utilization of Bufonis Venenum resources and the establishment of a rational quality evaluation system of Bufonis Venenum.

OBJECTIVE To investigate the effects of the compo nents of traditional Chinese medicine （TCM）（total ginsenoside，total ketone ester of Ginkgo biloba ，total glucoside of Crocus sativus ）for invigorating qi and activating blood circulation on cognitive function of mice with chronic cerebral ischemia （CCI）and its related mechanisms . METHODS CCI model was established by stimulating bilateral common carotid arteries of C 57BL/6J mice with temperature controlled current . Model mice were randomly divided into model group ，aspirin group （positive control 10 mg/kg）and TCM group （the components of TCM for invigorating qi and activating blood circulation 33 mg/kg），sham operation group was set up additionally ，with 16 mice in each group. Except that the mice in model group and sham operation group were given water intragastrically ，the mice in the other groups were given corresponding medicine liquid intragastrically，once a day ，for 8 weeks. The latency of step down and the number of step -down errors of mice in each group were detected ；the ultrastructure of neurovascular units（NVU）in cerebral cortex and hippocampus was observed ；the protein and mRNA expressions of vascular endothelial growth factor（VEGF）and α7 nicotinic acetylcholine receptors （α7nAChRs） in cerebral tissue were detected ；the contents of VEGF，angiopoietin 1 （Ang1） and basic fibroblast growth factor（bFGF）were detected . RESULTS Compared with model group ，the latency of step -down was significantly prolonged （P＜ 0.05），and the number of step -down errors was significantly reduced （P＜0.05）in TCM group . The ultrastructural abnormalities of NVU in cerebral cortex and hippocampus were significantly improved ，and the protein and mRNA expressions of VEGF and α7 nAChRs and the contents of VEGF ，Ang1 and bFGF in cerebral tissue were significantly increased （P＜0.05）. CONCLUSIONS The components of TCM for invigorating qi and activating blood circulation can improve CCI -induced cognitive dysfunction in mice，the mechanism of which may be associated with protecting NVU ，recovering ultrastructural abnormalities of injured NVU ， and regulating the expression of proteins closely related to NVU and memory function .
