Objective To investigate the correlation between the hemoglobin glycation index(HGI)and the severity of intraplaque neovascularization(IPN)in patients with mild-to-moderate carotid artery stenosis.Methods This study retrospectively and consecutively enrolled patients with mild-to-moderate carotid artery stenosis(＜70%narrowing)hospitalized in the Department of Neurology at the Hefei Second People's Hospital between June,2020 and June,2024.Demographic data(age,gender),personal history(smoking,drinking),cerebrovascular risk factors(hypertension,diabetes,hyperlipidemia),body mass index,and laboratory indicators from fasting venous blood collected on the second morning of hospital admission(neutrophils,lymphocytes,neutrophil-to-lymphocyte ratio,platelet count,total cholesterol,triglycerides,high-density lipoprotein cholesterol,low-density lipoprotein cholesterol(LDL-C),homocysteine,blood glucose,and glycated hemoglobin[HbA1c])were collected and compared.A univariate linear regression analysis was performed to assess the relationship between fasting blood glucose and HbA1c levels measured on the second day after admission,yielding the prediction formula:predicted HbA1c(%)=0.571×fasting blood glucose(mmol/L)+3.125.Subsequently,HGI was calculated through:HGI=actual HbA1c-predicted HbA1c.Carotid ultrasound was used to measure patients'carotid intima-media thickness,and,plaque location,thickness(maximum plaque diameter),length,echogenicity,and resistance index.For patients with multiple plaques,the thickest plaque was selected as the target plaque.Using the AngioPLUS mode of carotid ultrasound,dynamically observe for presence of IPN at the filling defect of the carotid artery plaque.The IPN condition of the target plaque was then assessed,including the number,location,morphology(e.g.,punctate,short linear,etc.),and spectral Doppler characteristics of the new blood vessels.The IPN signals were counted and scored according to the following criteria:absence of high-echogenicity blood flow signals in the target carotid artery plaque indicating no neovascularization,was scored as 0 point;the presence of fewer than 4 punctate or short linear hyperechoic blood flow signals within the target plaque was scored as 1 point;the presence of diffusely distributed(≥4)short linear or strip-like hyperechoic blood flow signals within the plaque was scored as 2 points.A higher IPN score indicates a more severe degree of IPN.Patients with an IPN score of 0-1 were categorized as the low IPN score group,while those with an IPN score of 2 were classified as the high IPN score group.Indicators with statistically significant differences between the two groups in the univariate analysis and exhibited no multicollinearity were included in the multivariate binary Logistic regression model to analyze the relationship between HGI and the severity of carotid IPN.Results A total of 387 patients(222 males and 165 females,with a mean age of[70±10]years)with mild-to-moderate carotid artery stenosis were included in this study.Among the 387 patients enrolled,97 were in the low IPN score group,while 290 were in the high IPN score group.(1)The high IPN score group exhibited significantly higher average age([71±10]years vs.[67±10]years),higher prevalence of hypertension(79.7%[231/290]vs.67.0%[65/97]),higher prevalence of diabetes(37.6%[109/290]vs.14.4%[14/97]),greater plaque thickness(2.40[2.00,3.10]mm vs.2.30[1.80,2.70]mm),higher HbA1c levels(6.25%[5.70%,7.20%]vs.5.80%[5.50%,6.40%]),and higher HGI values(-0.05%[-0.39%,0.46%]vs.-0.29%[-0.56%,-0.10%])in comparison to the low IPN score group(all P＜0.05).Additionally,the high IPN score group had significantly lower lymphocyte ratios([27.75±9.19]%vs.[30.17±9.04]%)and lower LDL-C levels([2.19±0.81]mmol/L vs.[2.43±0.91]mmol/L;both P＜0.05).(2)The results of multivariate Logistic regression analysis indicated that age(OR,1.031,95%CI 1.004-1.060,P=0.027),HGI(OR,1.782,95%CI 1.066-2.979,P=0.028),and plaque thickness(OR,1.750,95%CI 1.229-2.490,P=0.002)were independent influencing factors associated with the severity of IPN in the mild-to-moderate carotid artery stenosis.Conclusions High HGI may serve as an independent risk factor for the severe IPN in patients with mild-to-moderate carotid artery stenosis.However,the findings of this study require further validation through multi-center,large-scale,prospective clinical trials.

Cervical spinal cord injury without fracture-dislocation (CSCIWFD) is referred to as a special type of cervical spinal cord injury characterized by traumatic spinal cord dysfunction and no significant bony structural abnormalities on imagines. Duo to the high risk of missed diagnosis during the initial consultation, CSCIWFD may lead to progressive neurological deterioration or even complete paralysis, severely impacting patients′ prognosis. Currently, there are no established consensuses over the diagnosis and treatment of CSCIWFD, such as the lack of evidence-based standards for indications of non-surgical treatment and risk of secondary neurological injury, as well as debates over the optimal timing for surgical intervention and indications for different surgical approaches. To address these issues, the Spine Trauma Group of the Orthopedic Branch of the Chinese Medical Doctor Association organized experts in the relevant fields to formulate Diagnosis and treatment guideline for acute cervical spinal cord injury without fracture- dislocation in adults ( version 2025) . Based on evidence-based medicine and the principles of scientific rigor and clinical applicability, the guidelines proposed 11 recommendations covering terminology, diagnosis, evaluation treatment, and rehabilitation, etc., aiming to standardize the management of CSCIWFD.

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.

Hearing loss is the most prevalent disabling disease. Cochlear implantation（CI） serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system（Favorable, Marginal, Poor）. The consensus focuses on common hereditary non-syndromic hearing loss（such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1） and syndromic hereditary hearing loss（such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome）, which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.

Nitrogen narcosis is a neurological syndrome that manifests when humans or animals encounter hyperbaric nitrogen, resulting in a range of motor, emotional, and cognitive abnormalities. The anterior cingulate cortex (ACC) is known for its significant involvement in regulating motivation, cognition, and action. However, its specific contribution to nitrogen narcosis-induced hyperlocomotion and the underlying mechanisms remain poorly understood. Here we report that exposure to hyperbaric nitrogen notably increased the locomotor activity of mice in a pressure-dependent manner. Concurrently, this exposure induced heightened activation among neurons in both the ACC and dorsal medial striatum (DMS). Notably, chemogenetic inhibition of ACC neurons effectively suppressed hyperlocomotion. Conversely, chemogenetic excitation lowered the hyperbaric pressure threshold required to induce hyperlocomotion. Moreover, both chemogenetic inhibition and genetic ablation of activity-dependent neurons within the ACC reduced the hyperlocomotion. Further investigation revealed that ACC neurons project to the DMS, and chemogenetic inhibition of ACC-DMS projections resulted in a reduction in hyperlocomotion. Finally, nitrogen narcosis led to an increase in local field potentials in the theta frequency band and a decrease in the alpha frequency band in both the ACC and DMS. These results collectively suggest that excitatory neurons within the ACC, along with their projections to the DMS, play a pivotal role in regulating the hyperlocomotion induced by exposure to hyperbaric nitrogen.

Basket trial, as an innovative clinical trial design concept, marks the transformation of medical research from the traditional large-scale and single-disease treatment to the precise and individualized treatment. By gradually incorporating the Bayesian method during development, the trial design becomes more scientific and reasonable and increases its efficiency. The fundamental principle of the Bayesian method is the utilization of prior knowledge in conjunction with new observational data to dynamically update the posterior probability. This flexibility enhances the basket trial's capacity to effectively adapt to variations during the research process. Consequently, it enables researchers to dynamically adjust research strategies based on accumulated data and improve the predictive accuracy regarding treatment responses. In addition, the design concept of the basket trial aligns with the traditional Chinese medicine(TCM) principle of "homotherapy for heteropathy". The principle of "homotherapy for heteropathy" emphasizes that under certain conditions, different diseases may have the same treatment. Similarly, basket trials allow using a uniform trial design across multiple diseases, offering enhanced operational and significant practical value in the realm of TCM, particularly within the context of syndrome-based disease research. By introducing basket trials, the design of TCM clinical studies will be more scientific and yield higher-quality evidence. This study systematically categorized various Bayesian methods and models utilized in basket trials, evaluated their strengths and weaknesses, and identified their appropriate application contexts, so as to offer a practical guide for designing basket trials in the realm of TCM.

The chemical composition of Paeoniae Radix Alba(PRA) is complex, with primary secondary metabolites including monoterpenoids, tannins, triterpenoids, and flavonoids. In previous studies on the material basis of PRA, it was found that, in addition to the widely studied characteristic monoterpene glycosides, tannic acid components also play an important role in the efficacy of PRA. However, their pharmacological effects have not been thoroughly investigated. This paper reviews the tannic acid components in PRA, including pentagaloyl glucose(PGG), tetragaloyl glucose(TGG), trigaloyl glucose(TriGG), and gallic acid, along with their structures, properties, and characteristics to provide a detailed discussion of their pharmacological activities and related mechanisms, aiming to offer a theoretical basis for the material basis research and clinical application of PRA.
