Purpose::This study evaluated the methods and clinical effects of multidisciplinary collaborative treatment for occlusal reconstruction in patients with old jaw fractures and dentition defects.Methods::Patients with old jaw fractures and dentition defects who underwent occlusal reconstruction at the Third Affiliated Hospital of Air Force Military Medical University from January 2018 to December 2022 were enrolled. Clinical treatment was classified into 3 phases. In phase I, techniques such as orthognathic surgery, microsurgery, and distraction osteogenesis were employed to reconstruct the correct 3-dimensional (3D) jaw position relationship. In phase II, bone augmentation and soft tissue management techniques were utilized to address insufficient alveolar bone mass and poor gingival soft tissue conditions. In phase III, implant-supported overdentures or fixed dentures were used for occlusal reconstruction. A summary of treatment methods, clinical efficacy evaluation, comparative analysis of imageological examinations, and satisfaction questionnaire survey were utilized to evaluate the therapeutic efficacy in patients with traumatic old jaw fractures and dentition defects. All data are summarized using the arithmetic mean ± standard deviation and compared using independent sample t-tests. Results::In 15 patients with old jaw fractures and dentition defects (an average age of 32 years, ranging from 18 to 53 years), there were 7 cases of malocclusion of single maxillary fracture, 6 of malocclusion of single mandible fracture, and 2 of malocclusion of both maxillary and mandible fractures. There were 5 patients with single maxillary dentition defects, 2 with single mandibular dentition defects, and 8 with both maxillary and mandibular dentition defects. To reconstruct the correct 3D jaw positional relationship, 5 patients underwent Le Fort I osteotomy of the maxilla, 3 underwent bilateral sagittal split ramus osteotomy of the mandible, 4 underwent open reduction and internal fixation for old jaw fractures, 3 underwent temporomandibular joint surgery, and 4 underwent distraction osteogenesis. All patients underwent jawbone augmentation, of whom 4 patients underwent a free composite vascularized bone flap (26.66%) and the remaining patients underwent local alveolar bone augmentation. Free gingival graft and connective tissue graft were the main methods for soft tissue augmentation (73.33%). The 15 patients received 81 implants, of whom 11 patients received implant-supported fixed dentures and 4 received implant-supported removable dentures. The survival rate of all implants was 93.82%. The final imageological examination of 15 patients confirmed that the malocclusion was corrected, and the clinical treatment ultimately achieved occlusal function reconstruction. The patient satisfaction questionnaire survey showed that they were satisfied with the efficacy, phonetics, aesthetics, and comfort after treatment.Conclusion::Occlusal reconstruction of old jaw fractures and dentition defects requires a phased sequential comprehensive treatment, consisting of 3D spatial jaw correction, alveolar bone augmentation and soft tissue augmentation, and implant-supported occlusal reconstruction, achieving satisfactory clinical therapeutic efficacy.

Objective To investigate the effect of nobiletin on platelet-activating factor(PAF)metabolism in diabetic rats with renal injury.Methods Totally 72 rats were randomly divided into control group(n=10)and modeling group(n=62).The modeling group rats were induced to develop a diabetic rat model with renal injury and then further divided into the model group,aspirin group(20 mg/kg),and nobiletin low(50 mg/kg),medium(100 mg/kg),and high-dose(200 mg/kg)groups,each with 10 rats.After continuous oral administration for 6 weeks,rat body weight,kidney weight,and kidney index were measured.Histopathological assessments were conducted by using HE,periodic acid-Schiff staining(PAS),Masson staining,and transmission electron microscopy.Blood glucose levels,renal function,inflammatory factors,PAF and its regulatory factors were detected.Expression levels of PAF metabolism-related proteins,PAF-acetylhydrolase(PAFAH),PAF receptor(PAFR),and cholinephosphotransferase 1(CHPT1)in kidney tissues were assessed using Western blotting and immunohistochemistry.Results Following nobiletin intervention,rat body weight increased while kidney weight and kidney index decreased.Improvement in renal tissue pathology was observed,with reduced interstitial fibrosis and thinner basement membrane.Fasting blood glucose and glycated hemoglobin decreased,while fasting insulin showed no significant improvement.Urea nitrogen,blood creatinine,cystatin C,and 24-hour urinary protein excretion were reduced.Levels of interleukin(IL)-1α,IL-6,IL-8,and tumor necrosis factor(TNF-α)were lowered.PAF and its regulatory factors decreased.PAFR and CHPT1 expression decreased,while PAFAH increased.Conclusion Nobiletin can alleviate renal injury in diabetic rats with renal injury,improve kidney function,regulate blood glucose,and mitigate inflammatory response.Its mechanism may be associated with the modulation of platelet-activating factor metabolism.

Objective To analyze the relationship between dietary and lifestyle inflammatory scores and metabolic syndrome, diabetes mellitus, cardiovascular disease, non-alcoholic fatty liver disease, tumor and other common metabolic diseases, and to explore the impact of dietary and lifestyle inflammatory potential on metabolic diseases, so as to provide new ideas for the diagnosis, treatment and prevention of metabolic diseases. Methods Databases such as CNKI, Wanfang , and PubMed were searched, and literatures related to the dietary and lifestyle inflammatory scores (DLIS) and metabolic diseases were reviewed . Results Seven articles showed that dietary and lifestyle inflammation scores had a positive correlation with metabolic diseases, and two articles showed that only lifestyle inflammatory scores had a positive correlation with metabolic diseases. Conclusion Dietary and lifestyle inflammatory scores may be positively correlated with metabolic diseases, but some results are still controversial. Further studies are needed to prove the correlation between DLIS and metabolic diseases.

The cis-emodin-emodin dianthrone (compound 1) and trans-emodin-emodin dianthrone (compound 2) were extracted from Polygonum multiflorum Thunb. The protective effect and mechanism of compound 1 and compound 2 (emodin-emodin dianthrones) on acute liver injury induced by concanavalin A (ConA) in ICR mice was first investigated. The results indicated that emodin-emodin dianthrones at 1 mg·kg^-1 significantly reduced serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) level (P < 0.05). Emodin-emodin dianthrones also improved liver histopathological damage in liver-injured mice. The level of Bcl-2-associated X protein (Bax) mRNA in liver was significantly reduced by 1 mg·kg^-1 of emodin-emodin dianthrones, while the level of B-cell lymphoma-2 (Bcl-2) mRNA expression was significantly increased (P < 0.05). The protective activity of compounds 1 and 2 against hepatocyte injury was further evaluated by hydrogen peroxide (H₂O₂)-induced hepatocyte injury. Compounds 1 and 2 significantly inhibited H₂O₂-induced hepatocyte injury and reduced the levels of ALT, AST, alkaline phosphatase (ALP), and lactate dehydrogenase (LDH) in cell culture. Compounds 1 and 2 also significantly improved the cell survival rate and decreased H₂O₂-induced oxidative stress in hepatocytes. Compound 1 (0.5 µmol·L^-1) significantly increased the enzymatic activity of superoxide dismutase (SOD) in hepatocytes (P < 0.01), and 0.5 µmol·L^-1 of compound 2 significantly decreased the intracellular reactive oxygen species (ROS), increased SOD enzyme activity, and glutathione (GSH) content (P < 0.01). Compounds 1 and 2 at 0.5 µmol·L^-1 also inhibited hepatocyte apoptosis by increasing the protein expression ratio of Bcl-2/Bax (P < 0.05) and decreasing the protein expression ratio of cleaved caspase-3 and pro caspase-3 (P < 0.05). This study indicates that the emodin-emodin dianthrones from Polygonum multiflorum Thunb. have liver-protective activity. Compounds 1 and 2 exerted hepatoprotective effects by inhibiting apoptosis and oxidative stress. The study provides an important material basis for the hepatoprotective effect of commonly used amounts of Polygonum multiflorum Thunb.
