Digital technologies have become an integral part of complete denture restoration. With advancement in computer-aided design and computer-aided manufacturing (CAD/CAM), tools such as intraoral scanning, facial scanning, 3D printing, and numerical control machining are reshaping the workflow of complete denture restoration. Unlike conventional methods that rely heavily on clinical experience and manual techniques, digital technologies offer greater precision, predictability, and efficacy. They also streamline the process by reducing the number of patient visits and improving overall comfort. Despite these improvements, the clinical application of digital complete denture restoration still faces challenges that require further standardization. The major issues include appropriate case selection, establishing consistent digital workflows, and evaluating long-term outcomes. To address these challenges and provide clinical guidance for practitioners, this expert consensus outlines the principles, advantages, and limitations of digital complete denture technology. The aim of this review was to offer practical recommendations on indications, clinical procedures and precautions, evaluation metrics, and outcome assessment to support digital restoration of complete denture in clinical practice.

The incidence of allergic diseases in children is increasing, which has become a serious public health burden.Studies have shown that the interaction between the human body and microorganisms contributes to the establishment of immune tolerance.This evidence supports the use of microbial agents for the prevention and treatment of allergic diseases.Bacterial lysates (BLs) are immunomodulators composed of inactivated extracts of a variety of bacteria associated with respiratory tract infections.BLs act on the mucosal immune system and initiate downstream immune responses by activating dendritic cells, thereby restoring T helper cell 1/T helper cell 2 balance.Relevant studies have confirmed that BLs can alleviate the clinical symptoms of allergic diseases and may play a role in primary prevention.The immunomodulatory effect of BLs is affected by many factors such as product type, administration method, and administration regimen.In clinical application, the patient′s immune status should be evaluated to avoid immune exhaustion.This review summarizes the mechanism, clinical research progress and administration regimen of BLs, in order to provide evidence for clinical application.

Cancer is a key risk factor for venous thromboembolic events.The risk of VTE in tumor patients is 4 to 7 times that of non-tumor patients,which is the second cause of death after tumor progression or recurrence in cancer patients.Cancer associated thromboembolism results in delays or discontinuation of anti-cancer treatment and increased mortality.At present,clinical practice guidelines at home and abroad recommend risk assessment of venous thromboembolic events for cancer pa-tients.In this review,the risk assessment models were summarize for cancer-associated venous thromboembolism.

Objective:To investigate the action targets and mechanism of celastrol in alleviating liver inflammatory injuries using network pharmacology; To verify the key targets through liver ischemia-reperfusion injury inducing inflammation mouse model.Methods:The targets of celastrol were integrated by searching SymMap, BATMAN-TCM, TCMSP, HIT 2.0, LigTMap, SEA, SwissTarget, Super-PRED, STITCH databases. The molecular targets of hepatic inflammatory injuries were investigated by GeneCards and DisGeNET databases. The intersection of drug targets and disease targets was obtained by Venn diagram to obtain the possible targets of celastrol in alleviating hepatic inflammatory diseases. Cytoscape 3.9.1 software was used to analyze the key targets of protein interaction (PPI) networks based on STRING database, and enrichment analysis was conducted through DAVID database. Based on the key targets, the ceRNA network was mapped by retrieving the starBase database. Molecular docking was used to evaluated the binding of celastrol with the key target proteins. The mice were divided into sham-operation solvent group, sham- operation medication group, model group, and Tripterygium wilfordii extract low- (0.1 mg/kg), medium- (0.3 mg/kg), and high- (1 mg/kg) dosage groups according to body weight, with 3-4 mice in each group. After 7 days of corresponding drug intervention, except for the sham-operation solvent group and sham-operation medication group, other groups were prepared with ischemia-reperfusion induced liver inflammation mouse models. The serum transaminase levels in mice were detected; the pathological morphology of mouse liver tissue was observed using HE staining; the expressions of IL-6 and TNF-α were detected in liver tissue using immunohistochemistry staining.Results:The key targets of celastrol in alleviating liver inflammation were inflammatory cytokines such as IL6 and TNF. The analysis of functional enrichment results showed that the key signaling pathways of Tripterygium wilfordii extract in reducing liver inflammatory injury included inflammatory response, cell apoptosis and proliferation, HIF1, and other pathways. Triptolide pretreatment could reduce serum aminotransferase level ( P<0.01) and liver inflammatory factors expression such as IL-6 and TNF-α ( P<0.05, P<0.01) after hepatic ischemia-reperfusion. Conclusion:Celastrol can alleviate hepatic ischemia-reperfusion injury, and its mechanism is closely related to the reduction of inflammatory factors such as IL-6 and TNF-α and the alleviation of hepatic inflammatory injury.

Objective To evaluate the effect of photo-activated disinfection(PAD)as a kind of adjuvant treatment on moderate to severe chronic periodontitis.Methods 21 patients with the chronic periodontitis(totally 218 selected sites)were randomly enrolled and divided into group A(minocycline hydrochloride),group B(PAD),group C(PAD + minocycline hydrochloride),and group D(no adjunctive therapy)for the adjunctive treatment after receiving the scaling and root planing(SRP).Periodontal indexs as probing depth(PD),bleeding on probing(BOP)and clinical attachment loss(CAL)were examined at the baseline,6 and 12 weeks after the treatment.Meanwhile,periodontal pathogens as Porphyromonas gingivalis(Pg)and Tannerella forsythia(Tf)from subgingival plaque of group A,B and C were detected by Real-time PCR.Results Compared with the baseline,the periodontal inflammations of all groups were improved signiffcantly at 6 and 12 weeks after the treatment(P<0.001),and group A,group B and group C were better than group D(P<0.001),group C was better than group A(P<0.001);Furthermore,the concentration of Pg and Tf was decreased significantly(P<0.001),and there was no difference among the three groups with adjunctive therapy.Conclussion As the adjunctive treatment of SRP,PAD could achieve the same and even better effect than minocycline hydrochloride ointment.

Objective:To analyze the detection of non-alcoholic fatty liver disease (NAFLD) and the multiple corresponding relationships of its risk factors in a middle-aged and young adult population undergoing health check-ups.Methods:This study was a cross-sectional study conducted on 15 423 individuals aged between 18 and 59 who underwent health check-ups at the Health Management Center of Henan Provincial Hospital of Traditional Chinese Medicine from January to December 2021. Relevant health examination data was collected, including basic information (age, gender, past medical history, smoking and alcohol consumption), physical examination, laboratory indicators such as blood lipids and blood glucose, and abdominal ultrasound results. The chi-square test was used to compare the prevalence of NAFLD among different characteristics of the population, and multiple correspondence analysis was employed for statistical analysis of related influencing factors.Results:A total of 5 859 cases of NAFLD were detected in this study, with a detection rate of 37.99%. The detection rate of NAFLD gradually increased with age ( χ2=828.841, P<0.001) and body mass index (BMI) ( χ2=1 889.809, P<0.001). The detection rates of NAFLD were higher in individuals with hypertension, diabetes, hypercholesterolemia, hypertriglyceridemia, low high-density lipoprotein cholesterolemia, high low-density lipoprotein cholesterolemia, and hyperuricemia compared to those without these conditions ( χ2 value was 1 223.673, 364.808, 444.074, 2 436.765, 1 323.736, 591.478, and 943.069, respectively, all P<0.001). Multiple correspondence analysis revealed that NAFLD was closely related to hypertension, hypertriglyceridemia, diabetes, hyperuricemia, overweight, obesity, and the age group of 45-49 years. Correspondence analysis graphs for males and females showed associations between NAFLD and hypertension, hypertriglyceridemia, hyperuricemia, overweight, and obesity. In males, NAFLD was closely related to the age group of 35-49 years, while in females, it was closely associated with the age group of 45-49 years and diabetes. Conclusions:The detection rate of non-alcoholic fatty liver disease is relatively high in middle-aged and young adult populations. Males, those who are overweight or obese, and individuals with hypertension, diabetes, hyperuricemia, or abnormal blood lipids are more susceptible to non-alcoholic fatty liver disease.

Objective:To explore the efficacy of stage I modified posterior vertebral column resection (mPVCR) in the treatment of postoperative infection after percutaneous vertebroplasty (PVP) for osteoporotic vertebral compression fracture (OVCF).Methods:A retrospective case series study was conducted to analyze the clinical data of 11 OVCF patients with post-PVP infection who were admitted to Zhengzhou Orthopedics Hospital from January 2016 to June 2022, including 4 males and 7 females, aged 61-81 years [(70.2±6.4)years]. Injured segments included T 9 in 1 patient, T 11 in 2, T 12 in 3, L 1 in 1, L 2 in 2, T 11-T 12 in 1, and T 12-L 1 in 1. American Spinal Injury Association (ASIA) grading was grade D in 5 patients and grade E in 6. All the patients were treated with stage I mPVCR. The operation time and intraoperative bleeding volume were recorded. The values of Visual Analogue Scale (VAS), Oswestry Dysfunction Index (ODI), and Cobb angle of the lesion segments before, at 2 weeks, 3 months after surgery, and at the last follow-up were compared. The loss of Cobb angle of the lesion segments at 2 weeks after surgery and at the last follow-up were compared, and the ASIA grading at the last follow-up was recorded. The infection control, bone healing, and the incidence of complications were observed at the last follow-up. Results:All the patients were followed up for 12-44 months [(26.0±9.4)months]. The operation time and intraoperative bleeding volume were 230-330 minutes [(279.2±28.6)minutes] and 500-1 100 ml [(840.9±184.1)ml] respectively. At 2 weeks, 3 months after surgery and at the last follow-up, the VAS scores were (4.0±0.8)points, (2.7±0.9)points, and (2.4±0.7)points respectively, which were all lower than that before surgery [(8.1±1.2)points] ( P<0.01); the ODI was (45.5±5.1)%, (30.0±6.5)%, and (18.5±3.6)% respectively, which were all lower than that before surgery [(78.7±6.2)%] ( P<0.01); the Cobb angle of the lesion segments were (7.9±1.4)°, (8.5±1.4)°, and (9.2±1.5)° respectively, which were lower than that before surgery [(25.5±9.2)°] ( P<0.01). The VAS and ODI were both improved at 3 months after surgery compared with those at 2 weeks after surgery ( P<0.05), while there was no significant difference in Cobb angle of the lesion segments ( P>0.05). The ODI was further improved at the last follow-up compared with that at 3 months after surgery ( P<0.05), while there were no significant differences in VAS or Cobb angle of the lesion segments ( P>0.05). The loss of Cobb angle correction of the lesion segment at the last follow-up was 0.96 (0.69, 1.45)° compared with that at 2 weeks after surgery and the rate of loss of Cobb angle correction of the lesion segment was 4.4(2.2, 7.4)%. At the last follow-up, the ASIA grading was grade E for all the patients, who were able to walk normally independently. The infection was all cured and good bony fusion was observed in the operated area at the last follow-up. Two patients had pleural effusion and pulmonary atelectasis, 1 incision fat liquefaction, and 1 pneumonia after the surgery. None of the patients had internal fixation failure and serious complications such as worsening neurological symptoms or death. Conclusion:Stage I mPVCR for the treatment of post-PVP infection in patients with OVCF is proved to attain significant pain relief and functional improvement, good correction results, effective reconstruction of spinal stability, complete removal of infected lesions, and few serious complications.

Objective:To investigate the efficacy of one-stage posterior-anterior combined operation for the treatment of abnormal fusion after facet joint dislocation in the subaxial cervical spine.Methods:A retrospective study of case series was conducted to analyze the clinical data of 10 patients with abnormal fusion after facet joint dislocation in the subaxial cervical spine who had been admitted to Department of Spine Surgery, Zhengzhou Orthopedic Hospital from January 2015 to May 2023. There were 7 males and 3 females with an age of (41.2±3.1) years. Preoperative American Spinal Injury Association (ASIA) grading: 5 cases of grade A, 4 cases of grade B, and 1 cases of grade C. All the patients were treated with one-stage posterior-anterior combined operation. The surgical time and intraoperative bleeding volume were recorded. The ASIA grading was used to evaluate the improvements in nerve function of the spinal cord 3 months after surgery. The VAS scores, cervical intervertebral heights, and Cobb angles were compared between pre-surgery, 3 months after surgery, and the last follow-up. The fusion of intervertebral bone graft was evaluated 3 months after surgery using the Bridgell intervertebral fusion criteria. Complications were observed.Results:All patients were followed up for 15.5 (13.8, 20.5) months. The surgical time was (119.5±3.6) minutes, and the intraoperative bleeding volume (141.6±25.6) mL. Significant improvements in VAS score, cervical intervertebral height, and Cobb angle were observed at 3 months after surgery and the last follow-up compared with the pre-surgery values ( P<0.05), but there was no statistically significant difference between 3 months after surgery and the last follow-up ( P>0.05). ASIA grading 3 months after surgery: 4 cases of grade A, 4 cases of grade B, and 2 cases of grade C. By the Bridgell intervertebral fusion criteria at 3 months after surgery: 9 cases of grade Ⅰ and 1 cases of grade Ⅱ, showing good intervertebral fusion. Surgery went on well for all patients, showing no postoperative complications such as aggravation of nerve lesion or vascular injury. Conclusion:In the treatment of abnormal fusion after facet joint dislocation in the subaxial cervical spine, the efficacy of one-stage posterior-anterior combined operation is definite because it can effectively reduce pain, restore the height and physiological curvature of the cervical intervertebral space, and achieve good intervertebral fusion.

Objective:To evaluate the application of digital visualization in preoperative planning for surgical clearance of vertebral infection lesions following percutaneous vertebroplasty (PVP).Methods:A retrospective study was conducted to analyze the 13 patients with infectious spondylitis following PVP who had undergone one-stage posterior debridement and interbody bone grafting combined with instrumentation at Department of Spinal Surgery, Zhengzhou Orthopaedics Hospital from January 2016 to December 2022. They were 4 males and 9 females with an age of (71.4±6.5) years. Before surgery, the CT raw data of the patients were imported into software Mimics to reconstruct a three-dimensional model of the spine. After the distribution of bone cement in the model and its relationships with the vertebral plate, pedicle, articular process, and spinal cord were observed, a safe area for spinal canal surgery was designed. Intraoperative operations were carried out according to the preoperative planning. Surgical time, intraoperative blood loss, improvements in American Spinal Injury Association (ASIA) grading, and postoperative complications were recorded. The therapeutic efficacy was evaluated by comparisons of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), visual analogue scale (VAS), and Oswestry disability index (ODI) between preoperation, 2 weeks and 3 months postoperation, and the last follow-up.Results:Surgery went on successfully in all the 13 patients according to the preoperative planning. The surgical time was (275.9±28.3) min and the intraoperative blood loss (865.4±183.0) mL. All patients were followed up for (24.7±9.4) months. The levels of ESR, CRP, VAS, and ODI at 2 weeks, 3 months and the last follow-up were significantly lower than those before surgery ( P<0.05). At the last follow-up, X-ray and CT examinations showed good positions of internal fixation and sufficient bone graft fusion. The ASIA grading recovered from preoperative D to E in 5 patients. No incision infection, sinus formation, worsening of neurological symptoms, loosening or rupture of internal fixation, or worsening of neurological dysfunction were found. Conclusion:With the assistance of 3D visualization, the spinal cord, bone cement, and debridement area can be visualized directly to reduce nerve injury complications so that a safe and effective preoperative planning can be made for surgical clearance of vertebral infection lesions following PVP.

Objectives:To explore the microanatomy and functional MRI(fMRI) of arcuate fasciculus(AF) and superior longitudinal fasciculus(SLF),and to analyze their functions.Methods:Ten normal adult cadaveric head specimens (20 cerebral hemispheres) were fixed with 10% methanal at the Translational Research Institute for Neurological Disorders of the Wannan Medical College from February to December 2022.The Klingler fiber dissection technique was utilized to perform white matter fiber dissection,with a magnification ranging from 6 to 40.The study focused on the microanatomical structures of the AF and SLF,aiming to explore their relationships with deep brain fibers.Furthermore, six healthy adult volunteers who underwent fMRI of the brain were included.The collected diffusion tensor imaging (DTI) data were processed and integrated with the microanatomical findings for a comprehensive analysis.Results:After removing the gray matter of the cerebral cortex,the superficial U fibers were exposed.The long association fibers that beneath the U fibers were the AF and SLF,which were the main long association fibers in the superficial layers of the brain.The AF could be divided into dorsal and ventral parts,while the SLF could be divided into Ⅰ,Ⅱ,and Ⅲ.SLF Ⅰ lied within the upper bank of the cingulate sulcus,travels medial to the callosal sulcus.The SLF Ⅱ,Ⅲ,and the AF were located on the lateral surface of the brain.By removing the gray matter of the insular cortex and the extreme capsule,exposing the external capsule and claustrum.Subsequently,the AF and SLF Ⅱ,Ⅲ were dissected,revealing the corona radiata and sagittal stratum,along with other deep brain fibers.During the dissection,it was observed that there was a close connection between the AF,SLF Ⅱ,and the deep brain fibers.Furthermore,in the regions above the lateral fissure of the cerebral hemisphere,there was no direct connection of long association fibers between the gray matter cortex and the deep U fibers in the coronal plane.These findings were further supported by DTI studies.Conclusions:The AF and SLF are the major long association fibers that located in the superficial layers of the brain,and closely connect to the gray matter cortex and U fibers,even closely relate with deep brain fibers.In the regions above the lateral fissure of the hemisphere,only the AF and SLF Ⅱ and Ⅲ serve as superficial long association fibers in the anterior-posterior direction.These fibers are likely involved in the transmission of brain functional information between the top and bottom gray matter cortex in the coronal plane above the lateral fissure.
