ObjectiveThis study aims to explore the mechanism by which Yishen Huoxue Tongqiao Formula improves metabolism-neuroplasticity and treats unilateral vestibular labyrinth destruction by regulating the metabolic balance of glutamate （Glu）/γ-aminobutyric acid （GABA）. Methods48 Sprague-Dawley （SD） adult rats were randomly divided into the sham operation group， model group， Yishen Huoxue Tongqiao Formula groups with low， medium， and high doses （9.20， 18.39， 36.78 g·kg^-1）， and betahistine group （1.62 mg·kg^-1）. A unilateral vestibular labyrinth destruction （vestibular dysfunction） model was established by intratympanic injection of chloroform into the right ear， while the control group received intratympanic injection of normal saline. Drugs were administered once daily for seven consecutive days. During the period， behavioral tests were performed to evaluate the behaviors of rats after unilateral vestibular labyrinth destruction. Hematoxylin-eosin （HE） staining and Nissl staining were used to observe the neuronal morphology in the medial vestibular nucleus. Golgi staining was employed to assess the number of dendritic spines of neurons in the medial vestibular nucleus. Ultra-performance liquid chromatography-tandem mass spectrometry （LC-ESI-MS/MS） was utilized to detect Glu/GABA. Immunofluorescence and immunohistochemistry were used to detect the expressions of neuronal nuclei （NeuN）， growth-associated protein 43 （GAP-43）， and glial fibrillary acidic protein （GFAP）. Western blot and real-time fluorescent quantitative polymerase chain reaction （Real-time PCR） were applied to determine the expressions of glutamate-immunoreactive （Glu-IR）， GABA， GFAP， postsynaptic density protein 95 （PSD-95）， and GAP-43. ResultsCompared with the sham operation group， the model group presented with head deviation， balance disorder， increased tail suspension score， nuclear consolidation of medial vestibular nerve neurons， and decreased Nissl bodies （P<0.01）. The number of dendritic spines in neurons and NeuN-positive cells decreased. The content of Glu decreased. The content of GABA increased （Glu/GABA decreased）. The expression of GAP-43 was down-regulated， and GFAP was up-regulated （P<0.05， P<0.01）. The expressions of Glu-IR， PSD-95， and GAP-43 proteins， as well as Glu-IR mRNA decreased， while the expressions of GABA and GFAP proteins and mRNA increased （P<0.05， P<0.01）. Compared with those in the model group， the head deviation， imbalanced behavior， and tail suspension scores in each treatment group decreased， with alleviated neuronal injury and recovered Nissl bodies （P<0.01）. The number of dendritic spines of neurons increased， and the number of NeuN-positive cells rebounded. The content of Glu increased， and the content of GABA decreased （Glu/GABA increased）. GFAP was down-regulated， and GAP-43 was up-regulated （P<0.05， P<0.01）. The expressions of Glu-IR， PMD-95， and GAP-43 proteins， as well as Glu-IR mRNA increased， while the expressions of GABA and GFAP proteins and mRNA decreased. The effect was more significant in the high-dose group （P<0.01）. ConclusionThe Yishen Huoxue Tongqiao Formula can alleviate vestibular dysfunction， and its mechanism may be associated with regulating the metabolic balance of Glu/GABA， mitigating neural damage， improving synaptic plasticity （promoting GAP-43 expression and inhibiting GFAP expression）， and facilitating vestibular compensation.

Objective Based on data from the Global Burden of Disease Study 2023 (GBD 2023), this study analyzes the trends in disease burden and years lived with disability (YLD) of bladder cancer in China from 1990 to 2023. Methods Epidemiological data on bladder cancer in China were obtained from the GBD 2023 database.The age-standardized prevalence rate (ASPR), YLD and population attributable fraction (PAF) of risk factors were calculated.Temporal trends were evaluated using the estimated annual percentage change (EAPC), and Joinpoint regression was applied to compute the annual percent change (APC) and average annual percent change (AAPC) for trend analysis. Results Between 1990 and 2023, the number of bladder cancer patients requiring rehabilitation services increased from 213 568 cases to 587 191 cases, representing a 175.0% increase.The YLD rose from 22 158 to 56 620, marking a 155.6% growth.The ASPR increased from 22.6/100 000 to 25.7/100 000 (EAPC=0.06), indicating a stable trend.The age-standardized YLD rate (ASYR) remained at 2.5/100 000 (EAPC=-0.32), indicating a downward trend.Notably, gender disparities in disease burden were evident, with male patients and YLD being 4.63 times and 4.25 times higher than their female counterparts, respectively.Risk factor analysis showed that smoking and high fasting plasma glucose were the main risk factors for bladder cancer.The ASYR attributable to high fasting plasma glucose showed an increasing trend in males (EAPC=0.13) but a decreasing trend in females (EAPC=-1.41). Conclusion The demand for rehabilitation and disease burden of bladder cancer in China have significantly increased, with particularly heavy burdens among males and the elderly population.It is urgent to formulate targeted interventions, strengthen tobacco control, occupational protection, and weight management, and establish an integrated rehabilitation service system to address the increasingly severe disease burden caused by bladder cancer.

Objective:This study aimed to clarify clinicopathologic characteristics, postoperative complications, and related risk factors of elderly patients with gastric cancer.Methods:A total of 395 patients(≥65 years old)who underwent radical gastrectomy for gastric cancer in Beijing Hospital from January 2014 to December 2021 were enrolled in this study.The patients were divided into the common elderly group(age<80 years, n=340)and the high-age group(age ≥ 80 years, n=55). Postoperative complications were classified into medical and surgical types.The clinicopathological characteristics and complications were compared between the two groups.Logistic regression models(univariate and multivariate)were used to identify the risk factors for postoperative complications.Results:The common elderly group was 65-79 years old(mean age: 71.5±4.3 years), with 263 male(77.4%); The high-age group was 80-89 years old(mean age: 82.6±2.6 years), with 42 male(76.4%). The comorbidity rate and the number of comorbidities in the high-age group were significantly higher than those in the common elderly group.The American Society of Anesthesiologists(ASA)scores and nutritional risk screening(NRS)2002 scores in the high-age group were significantly higher than those in the common elderly group(both P<0.05), and the activities of daily living(ADL)scores in the high-age group were significantly lower than that in the common elderly group( P<0.001). There were no statistically significant differences in tumor location, degree of differentiation, pathological type, T stage, and N stage between the two groups(all P>0.05). The overall postoperative complication rate in the high-age group was significantly higher than that in the common elderly group(38.2% vs.24.7%, P=0.036); the medical complications were significantly increased in the high-age group(21.8% vs.10.9%, P=0.022), whereas the surgical complications did not increase significantly(25.5% vs.17.1%, P=0.135). Multivariate analysis revealed that the number of comorbidities ≥2( HR=2.502, 95% CI: 1.275-4.911, P=0.008), preoperative NRS 2002 scores ≥5( HR=2.714, 95% CI1.294-5.693, P=0.008), and preoperative ADL scores<100( HR=2.012, 95% CI1.010-4.009, P=0.047)were independent risk factors for medical complications.Additionally, ASA grade ≥ 3( HR=2.586, 95% CI: 1.444-4.632, P=0.001)and proximal or distal gastrectomy( HR=2.397, 95% CI: 1.237-4.574, P=0.009)were independent risk factors for surgical complications. Conclusions:The occurrence of postoperative medical complications in very elderly patients with gastric cancer undergoing radical surgery has increased, while the rate of surgical complications has not increased.Moreover, advanced age itself is not an independent risk factor for postoperative complications.More attention should be paid to medical complications, and the management of commodities and nutritional support should be strengthened during the perioperative period.

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.

Orthodontic treatment is the primary method for correcting malocclusion.However,with the continuous increase in the number of patients,the shortage of orthodontists and the lack of standardized diagnosis and treatment have become increasingly prominent,resulting in difficulties in patients'access to care and variability in treatment quality.Traditional orthodontic diagnosis and treatment heavily rely on doctors'experience,which is highly subjective and inefficient,and thus cannot meet the growing demand for precise and standardized medical care.The strengths of artificial intelligence(AI)in data processing,pattern recognition,and intelligent decision-making offer new technological pathways to address these issues.In recent years,AI-based diagnostic and therapeutic systems have shown great potential in improving efficiency in orthodontics and optimizing the consistency of treatment outcomes.This article systematically reviews the advances in the application of AI technology in clinical orthodontic diagnosis and treatment,focusing on its innovative practices in intelligent data acquisition,automated imaging analysis,personalized treatment planning,efficacy prediction modeling,telemedicine,and digital file management,aiming to provide a theoretical basis for promoting the intelligent and standardized development of orthodontic diagnosis and treatment.

Atherosclerosis is a chronic vascular inflammatory disease caused by abnormal lipid metabolism.The formation of lipid-rich foam cells acts as the initial trigger for development of atherosclerotic lesions.Recent studies have shown that lipophagy,a form of selective autophagy,can selectively degrade lipid droplets stored intracellularly and promote cholesterol efflux through the autophagic lysosomal pathway.As a result,intracellular lipid accumulation is re-duced and foaming is inhibited,making lipophagy a potential new target for current anti-atherosclerosis therapy.This arti-cle reviews the crucial role and molecular mechanism of lipophagy in the link between lipid metabolism and atherosclero-sis.Its objective is to outline the regulatory mechanism of lipophagy and present fresh insights for the treatment of athero-sclerotic diseases.

Objective:To investigate the regulatory role of miR-17-5p on B7-H3 and its immunomodulatory role in the develop-ment of colorectal cancer.Methods:Twenty-five pairs of human colorectal cancer tissues and adjacent normal tissues were collected,and the expression levels of miR-17-5p,B7-H3 and PD-L1 were analyzed by real-time fluorescence quantitative PCR,protein immuno-blotting and immunohistochemical assays.Human colorectal cancer HCT-116 cells were divided into four groups:miR-NC group,miR-17-5p mimic group,si-NC group and si-B7-H3 group.The growth,invasive ability and apoptosis rate of HCT-116 cells were ana-lyzed by cell colony formation assay,Transwell assay and flow cytometry.The regulatory effect of miR-17-5p on B7-H3 was analyzed by luciferase reporter gene assay.The levels of IL-2,IL-4,IL-6,IL-10,IFN-γ and TNF-α cytokines in the cell culture medium were analyzed by ELISA.Results:Compared with paracancerous tissues,miR-17-5p expression was decreased and B7-H3 expression was increased in colorectal cancer tissues.miR-17-5p mimic and si-B7-H3 were able to reduce the number of HCT-116 cell colony forma-tion and invasion,promote HCT-116 cell apoptosis,and decrease the levels of IL-2,IL-4,IL-6,IL-10,IFN-γ and TNF-α cytokines in culture medium.In addition,miR-17-5p mimic and si B7-H3 were able to inhibit PD-L1 expression in HCT-116 cells.Conclusion:miR-17-5p can targeting inhibit B7-H3 expression,affect the immunomodulatory role in colorectal cancer development,and inhibit metastasis and promote apoptosis of colorectal cancer cells.
