AIM: To analyze the influencing factors of cognitive dysfunction in patients with open angle glaucoma, and construct a risk prediction decision tree model. METHODS:Retrospective study. The clinical data of patients with open angle glaucoma treated in the hospital from February 2022 to November 2024 were collected, and patients were divided into a cognitive dysfunction group and a cognitive function normal group according to the evaluation results of the Montreal Cognitive Assessment Scale(MoCA)at the time of admission, and the clinical data of the two groups were compared. The influencing factors of cognitive dysfunction in patients with open angle glaucoma were analyzed through Logistic regression model, and the decision tree model was analyzed and constructed based on the clinical data of the two groups through the decision tree CHAID algorithm, and the predictive performance of two models was compared using receiver operating characteristic(ROC)curves. RESULTS:The total of 179 patients with open angle glaucoma were included in this study, and were divided into a cognitive dysfunction group of 107 cases(59 males and 48 females, with 66 cases aged ≥60 y)and a cognitive function normal group of 72 cases(34 males and 38 females, with 28 cases aged ≥60 y)according to the MoCA assessment results at the time of patient admission.The incidence of cognitive dysfunction was 59.8%(107/179). The proportion of age ≥60y, education level of junior high school or below, hypertension, sleep disorders, and middle/late stage diseases in the cognitive dysfunction group were higher than those in the cognitive function normal group(all P<0.05). Logistic regression analysis showed that age ≥60 y, education level of junior high school or below, hypertension, sleep disorders, and middle/late stage disease were all risk factors for cognitive dysfunction in patients with open angle glaucoma(all P<0.05). The risk prediction decision tree model constructed using the decision tree CHAID algorithm included 4 layers and 11 nodes, and it outputed 5 risk variables: disease severity, age, sleep disorders, education level, and hypertension. Among them,the disease severity was the first layer risk variable. The ROC curve showed that the area under curve for predicting cognitive dysfunction in patients with open angle glaucoma using the risk prediction decision tree model and logistic regression model was 0.849 and 0.842 respectively, and there was no statistically significant difference in the predictive value between the two models(P>0.05). CONCLUSION: The disease severity, age, sleep disorders, education level, and hypertension are influencing factors for cognitive dysfunction in patients with open angle glaucoma, and the risk prediction decision tree model analyzed and constructed by the decision tree CHAID algorithm has good predictive value for cognitive dysfunction.

OBJECTIVES: This retrospective study aimed to investigate factors influencing positional changes of the condyle and temporomandibular joint (TMJ) following mandibular defect reconstruction with bone flaps, and to evaluate the biomechanical impacts of flap reconstruction on condylar positioning, thereby providing evidence for optimizing surgical protocols and TMJ functional rehabilitation. METHODS: A retrospective study was conducted on 90 patients undergoing mandibular segmental resection with immediate bone flap reconstruction at Guizhou Medical University Affiliated Stomatological Hospital (June 2019 to May 2024). After strict screening, 50 cases with complete data were analyzed. Clinical parameters (defect size, location, reconstruction method) and craniofacial CT scans at four timepoints [preoperative (T0), 7-10 days (T1), 3 months (T2), and 6 months (T3) postoperatively] were collected. Mimics 20 software facilitated 3D reconstruction for measuring TMJ anterior/posterior/superior joint spaces (Kamelchuk method) and calculating condylar position via the Pullinger index [Ln (posterior/anterior space)]. Vitral and Krisjane methods quantified mandibular linear parameters (ramus length, condylar pole distances to the sagittal plane, angulation) and glenoid fossa morphology. Statistical analyses were performed using SPSS 21.0. RESULTS: Mandibular defect size and location were significant factors influencing postoperative condylar position changes (P<0.05). Compared to preoperative measurements, postoperative condylar anterior, posterior, and superior joint spaces were significantly increased (P<0.001). The most pronounced anterior condylar displacement occurred within 7-10 days postoperatively (P<0.05). In patients with condyle resection, postoperative joint space and angle changes were significant; in patients with condyle preservation, only superior and anterior joint space changes were statistically significant (P<0.05). Additionally, from T1 to T2, the changes in condylar medial-lateral distance, superior joint space, and anterior joint space were negatively correlated with the preoperative condylar position. Compared with preoperative,in the T0-T1 period, condylar medial-lateral distance, posterior joint space, and articular tubercle angle changes were significantly negatively correlated with time (P<0.05). Notably, the angle between the condylar long axis and the coronal axis showed a sustained negative trend from T1 to T3 (P<0.05). CONCLUSIONS Condylar position changes after mandibular defect repair with bone flap reconstruction are associated with the size and location of the defect. Additionally, adaptive remodeling of the temporomandibular joint (TMJ) joint space occurs postoperatively. The phenomenon of anterior displacement of the condyle in the early postoperative period (7-10 days) shows a trend of reduction with prolonged follow-up time, and further sample size research is needed.

Surgical operation is the main treatment of oral and maxillofacial tumors.Dysphagia is a common postoperative complication.Swal-lowing disorder can not only lead to mis-aspiration,malnutrition,aspiration pneumonia and other serious consequences,but also may cause psychological problems and social communication barriers,affecting the quality of life of the patients.At present,there is no systematic evalua-tion and rehabilitation management plan for the problem of swallowing disorder after oral and maxillofacial tumor surgery in China.Combining the characteristics of postoperative swallowing disorder in patients with oral and maxillofacial tumors,summarizing the clinical experience of ex-perts in the field of tumor and rehabilitation,reviewing and summarizing relevant literature at home and abroad,and through joint discussion and modification,a group of national experts reached this consensus including the core contents of the screening of swallowing disorders,the phased assessment of prognosis and complications,and the implementation plan of comprehensive management such as nutrition management,respiratory management,swallowing function recovery,psychology and nursing during rehabilitation treatment,in order to improve the evalua-tion and rehabilitation of swallowing disorder after oral and maxillofacial tumor surgery in clinic.

Liver failure is a kind of acute and severe liver disease.Bone marrow-derived mesenchymal stem cells(BM-MSCs)have the function of differentiating into hepatocytes.Promotion of the regeneration of hepatocytes re-generation,inhibition of apoptosis,necrosis and inflammation of hepatocytes,may facilitate repairing damaged liver tissue and improving liver function.BM-MSCs have become a new choice with great application potential in the treatment of liver failure.

The activation of hepatic stellate cells (HSCs) and excessive deposition of extracellular matrix are the keys to the occurrence and development of liver fibrosis. Metabolic reprogramming supports the activation process of HSCs, which requires substantial energy to meet the corresponding energy requirements for liver fibrosis formation. This review focuses on the effect of metabolomic changes characterized by metabolic reprogramming on HSC activation and summarizes the characteristics of HSC energy metabolism reprogramming during the formation of liver fibrosis, with the aim to summarize research evidence for exploring the mechanism and developing strategies for the prevention and treatment of liver fibrosis.

Objective By analyzing the characteristics of hidden poisoning homicide cases,provide scientific references for grass-roots forensic examination and toxicological screening and provide direction for the efficient discovery of hidden or missed cases of poisoning homicide in non-natural death cases.Methods Poisoning incidents in Hunan Province from 2018 to 2023 were retrospectively analyzed and compiled using Origin and EXCEL software.Results There were a total of 149 poisoning homicide cases,with 15 occurring in urban areas(accounting for 10.1%)and 134 in rural areas(accounting for 89.9%).Out of the 46 cases that led to casualties,rodenticide poisoning was the most prevalent(accounting for 52.2%),followed by cyanide(4.3%),nitrite(4.3%),thallium(2.2%),and other forms of poisoning.These incidents were primarily concentrated in urban areas.The main way of poisoning was to mix poisons into drinking water(accounting for 28.3%),meals(26.1%),and dark or heavy seasoning(8.7%).There was no significant disparity in the gender distribution of suspects,although the number of male victims was notably higher than that of female victims.The suspects were predominantly between the ages of 19 and 45,while the victims were mostly between the ages of 46 and 60.Among the 103 cases that did not result in injury or death,99%occurred in rural areas,with more than 95%of the involved poisons included pungent pesticides or herbicides,while rodenticides accounted for the least(1.9%).Conclusion There are obvious urban-rural differences in the case occurrence areas and types of involved poisons in poisoning homicide cases.Therefore,it is imperative to focus on both urban and rural areas during the investigation and evidence collection process in suspected poisoning cases.

Tooth extraction is a common and widely employed therapeutic procedure in oral and maxillofacial surgery.Minimally invasive tooth extraction can reduce both physical and psychological trauma to the patients,and is widely recommended as a first-line clinical treatment.But currently no guidelines or consensus has been available to provide a systematic introduction of minimally invasive tooth extraction to guide the clinical practices.To address this issue,this consensus,based on a comprehensive literature review and clinical experiences of experts,systematically summarizes the indications,target patients,and contraindications of minimally invasive tooth extraction,the overall workflow of this procedure(preoperative preparation,surgical steps,postoperative management,postoperative instructions,medications,and follow-up),and its common postoperative complications to provide a comprehensive guidance for clinical application of this technique.

Objective To study the expression of domain protein ubiquitin 5(OTUD5)and ring finger protein 186(RNF186)in non-muscle invasive bladder cancer(NMIBC)and their relationship with clinicopathological characteristics and prognostic value.Methods A total of 106 NMIBC patients admitted to Tangshan Traditional Chinese Medicine Hospital from January 2019 to January 2020 were collected.OTUD5 and RNF186 expression in NMIBC cancer tissue and para-cancer tissue were detected by immunochemistry.The differences between OTUD5 and RNF186 expressions in NMIBC cancer tissues with different clinical and pathological characteristics were compared.Kaplan-Meier curve analysis(Log Rank test)was used to analyze the impact of OTUD5 and RNF186 expression on progression free survival of NMIBC.COX regression model analysis was used to analyze factors affecting progression free survival in NMIBC patients.Results The positive rates of OTUD5(62.26％)and RNF186(66.04％)in NMIBC cancer tissue were higher than those in adjacent tissues(11.32％,8.49％),with significant differences(x2=59.146,75.079,all P＜0.05).There was a significant positive correlation between OTUD5 and RNF186 expressions in NMIBC cancer(r=0.659,P＜0.05).The positive rates of OTUD5(72.97％,84.21％)and RNF186(77.03％,86.84％)in T1 stage and high-grade NMIBC cancer tissues were higher than those in Ta/Tis stage(37.50％,50.00％)and low-grade cancer tissues(40.63％,54.41％),and the differences were significant(x2=11.964,13.199;12.143,11.431,all P＜0.05).The 3-year cumulative progression free survival rate of patients in the OTUD5 positive group(40.91％)and RNF186 positive group(45.70％)were lower than that in the OTUD5 negative group(90.00％)and RNF186 negative group(86.11％)(Log Rank test x2=24.710,14.586,all P＜0.05).OTUD5 positive(OR=1.446,95％CI:1.086～1.925),RNF186 positive(OR=1.579,95％CI:1.132～2.024),Tumor TNM stage T1(OR=1.582,95％CI:1.219～2.054)and high pathological grade(OR=1.570,95％CI:1.188～2.074)were independent risk factors affecting progression free survival in NMIBC patients(all P＜0.001).Conclusion The increased expression of OTUD5 and RNF186 in cancer tissue of NMIBC patients are related to tumor TNM staging and pathological grading and are independent risk factors affecting the prognosis of NMIBC patients.

The biological clock(also known as the circadian rhythm)is the fundamental reliance for all organisms on Earth to adapt and survive in the Earth's rotation environment.Circadian rhythm is the most basic regulatory mechanism of life activities,and plays a key role in maintaining normal physiological and biochemical homeostasis,disease occurrence and treatment.Recent studies have shown that the biologi-cal clock plays an important role in the development of oral tissues and in the occurrence and treatment of oral diseases.Since there is cur-rently no guiding literature on the research methods of biological clock in stomatology,researchers mainly conduct research based on pub-lished references,which has led to controversy about the research methods of biological clock in stomatology,and there are many confusions about how to rationally apply the research methods of circadia rhythms.In view of this,this expert consensus summarizes the characteristics of the biological clock and analyzes the shortcomings of the current biological clock research in stomatology,and organizes relevant experts to summarize and recommend 10 principles as a reference for the rational implementation of the biological clock in stomatology research.
