As an innovative form of combining traditional aromatherapy with modern nasal medicine delivery technology， "olfactory administration of Chinese medicine" carries the theoretical essence of traditional Chinese medicine （TCM）， which is "moving and channeling Qi and fragrance， dredging and awakening the mind". Based on the systematic records of olfactory therapies in ancient books in emergency care， disorders of consciousness， lung system， and gynecological diseases， this paper examines the historical evolution of its clinical application， and elucidates the profound historical basis and theoretical feasibility of "olfactory administration of Chinese medicine" as a new form. Combined with the innovation and precise application of modern Chinese medicine olfactory agents in multi-system diseases such as nervous， respiratory， and cardiovascular diseases， this paper further analyzes the multi-dimensional mechanism of olfactory receptor pathway， olfactory brain pathway， nasal mucosal blood vessels， and lymphatic channels， and demonstrates its advantages of rapid onset， targeted brain entry， and systemic regulation. Under the background of continuous growth in the demand for external TCM treatment， continuous breakthroughs in the technology of nasal dosage forms， and increasingly accurate drug delivery paths， Chinese medicine olfactory agents have shown significant practical applicability and development potential. This study aims to provide theoretical support and practical direction for the system construction of this form.

Effective symptom management can alleviate the physical and psychological distress experienced by patients with cancer, improve quality of life, and contribute to treatment adherence and improve clinical outcomes. However, most existing guidelines are developed for healthcare professionals, and patients and the public have limited access to standardized and comprehensible guidance on symptom management. To address this gap and to facilitate effective communication and shared decision-making, this study proposes the development of a patient version of the cancer symptom management guideline. The development process will adhere to the methodological framework recommended by the Guidelines International Network and the World Health Organization. The GRADE approach will be employed to assess the certainty of evidence and to formulate recommendations. In addition, the process will be informed by the Appraisal of Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ) instrument and the Reporting Items for Practice Guidelines in Healthcare-Public or Patient Versions of Guidelines (RIGHT-PVG). This protocol outlines the establishment of the guideline working group, the identification and prioritization of key questions, evidence retrieval and appraisal, and the formulation of recommendations, with the aim of ensuring methodological rigor and transparency in the development of the patient guideline and providing methodological reference for similar guideline initiatives.

The nose-to-brain pathway refers to a significant drug delivery route through which substances traverse the unique anatomical structures of the nasal cavity to directly access the central nervous system， bypassing the blood-brain barrier. Its core advantage lies in utilizing the olfactory and trigeminal nerves， enabling peripheral drug administration to rapidly and efficiently reach the brain， thereby avoiding the drug loss and bioavailability reduction associated with oral or intravenous routes due to the circulatory system and blood-brain barrier limitations. In recent years， with in-depth research into the neuroanatomy of the olfactory system， nasal mucosal barrier properties， and neural regulatory mechanisms， the potential application of the nose-to-brain pathway in neurological diseases has attracted increasing attention. Traditional Chinese medicine （TCM） essential oils， characterized by strong lipophilicity， small molecular weights， volatility， and diverse chemical components， are highly compatible with the physiological characteristics of the nose-to-brain pathway， thus serving as promising carriers for brain-targeted drug delivery， enhancing drug bioavailability， and exerting neuroprotective effects. On this basis， this review systematically summarizes the anatomical and physiological bases for the delivery of TCM essential oils via the nose-to-brain pathway， the patterns of drug transport and brain distribution， clinical and animal study examples in neurological diseases， the associated molecular mechanisms and signaling pathways， and the progress in the development of novel nasal essential oil formulations. Additionally， the review analyzes the current challenges in this field and proposes strategies for future research and application. By systematically discussing the nose-to-brain pathway and the delivery mechanisms of TCM essential oils， this study aims to provide theoretical support for drug development， mechanism exploration， and formulation innovation in the treatment of neurological diseases， while also offering scientific guidance for further research and clinical applications of the nose-to-brain delivery system.

Objective To evaluate answers to typical clinical questions related to neuro-ophthalmology generated by Artificial Intelligence(AI)Large Language Models(LLM)and to explore the performance of neuro-ophthalmology-related questions on LLM in a multidimensional manner using objective and expert assessment.Methods Multicenter,random-ized,cross-sectional pilot study.Thirty typical questions related to neuro-ophthalmology were selected based on four per-spectives:definition,etiology,clinical manifestations and signs,and treatment and prognosis,and were analyzed quantita-tively using Deepseek,Wenxin Yiyin 4.0,Doubao,and Kimi 1.5,which are four open-source LLMs in China,and quantita-tively analyzed with objective assessment;and quantitatively rated by three ophthalmologists using expert assessment for 120 answer texts.Three ophthalmology experts quantitatively scored the 120 answer texts.Three ophthalmologists quantita-tively scored the 120 answer texts.Level 3,5,and 4 Likert scales were developed according to the completeness,accura-cy,professionalism,relevance,and criticality of the question texts,respectively.The best-performing LLM was selected,and its performance was observed across the four types of questions.Additionally,three other experts assessed whether the best-performing one could be evaluated as a substitute for real-world doctor-patient communication.Results In the objective Chinese text reading difficulty analysis,the differences in total word count among the four LLMs were statistically significant(all P＜0.001).Of the four LLMs,Kimi 1.5 performed the best,with frequencies of 61％,29％,and 41％for the highest scores in completeness(3),accuracy and professionalism(5),and relevance and usefulness(4),respective-ly.Kimi 1.5 performed more consistently on the questions on the four areas of neuro-ophthalmologic disorders:definition,etiology,clinical manifestations and signs,treatment,and prognosis,with no between-group differences(P＞0.05).Con-clusion Chinese language LLMs have great potential in the clinical application of neuro-ophthalmology.Kimi 1.5 outper-forms other LLMs in terms of completeness,accuracy,professionalism,relevance,and usefulness,but it still cannot re-place real-world doctor-patient communication.There is a need to explore new diagnostic and therapeutic model of AI+physician in the future.

Objective To investigate the clinical effect of elastic fixation of Endobutton plate with loop in the treatment of lower tibiofibular combined injury.Methods A total of 326 patients with lower tibiofibular joint injury combined with ankle fracture underwent surgical treatment from June 2019 to June 2021 were randomly divided into experimental group(163 cases)and control group(163 cases)by using a random number table.The control group was fixed with traditional steel plate screw,and the experimental group was fixed with elastic steel plate with loop Endobutton.Hospitalization and operation related indexes were compared between the two groups.The American Association of Foot and Ankle Surgery Ankle Function Score(AOFAS)was performed on the two groups at 2 and 6 months after surgery,respectively,and the reseparation rate of the lower tibiofibular union was evaluated and compared between the two groups at 6 months after surgery.Results There were no significant differences in operation time,blood loss,incision length,getting out of bed time and hospital stay between experimental group and control group(P＞0.05).The incidence of postoperative complications in experimental group was 2.45％,lower than that in control group(7.98％),and the difference between the two groups was statistically significant(P＜0.05).The incidence of postoperative complications in experimental group was 2.45％,lower than that in control group(7.98％),and the difference was statistically significant between the two groups(P＜0.05).The AOFAS scores of control group were(74.5±9.2)and(81.3±4.3)at 2 months and 6 months,respectively,and the excellent and good rate was 76.0％.AOFAS of experimental group were(82.3±5.3)points and(91.2±3.8)points at 2 months and 6 months after surgery,respectively,and the excellent and good rate was 93.2％,the above indexes of experimental group were higher than those of control group,and the difference between the two groups was statistically significant(P＜0.05).Reexamination 6 months after surgery the reseparation rate of lower tibiofibular combination was 12.8％in the control group and 2.4％in the experimental group,and the risk of reseparation in the experimental group was lower than that in the control group,with statistical significance(P＜0.05).Conclusion Elastic fixation using Endobutton plate with loop could be used in the treatment of ankle fracture with distal tibiofibular syndesmosis injury,which has a better effect of traditional internal fixation with plate and screws.

Objective:To assess the burden and development trends of tuberculosis (TB) in China from 1990 to 2021 to provide a reference for TB prevention strategies.Methods:Utilizing the 2021 Global Burden of Disease Study data, the study evaluates the burden of TB and latent TB infection (LTBI) in China using age-standardized incidence, prevalence, disability-adjusted life years (DALYs), and infection rates. The Joinpoint regression model was employed to analyze changing trends, and the autoregressive moving average model was integrated to forecast multidrug-resistant TB incidence and LTBI infection rates from 2022 to 2030.Results:In 2021, the age-standardized TB incidence in China was 36.28 per 100 000, the age-standardized prevalence was 30 557.45 per 100 000, the age-standardized DALY rate was 76.22 per 100 000, and the LTBI age-standardized infection rate was 30.48%. Compared to 1990, these figures dropped by 66.72%, 2.82%, 89.41%, and 2.47%, respectively. The age-standardized incidence, prevalence, DALY rate, and infection rate were elevated in individuals aged ≥70 years, and the TB burden was greater in males than in females. The age-standardized TB incidence declined between 1990 and 2021, while the proportion of multidrug-resistant TB patients among newly diagnosed cases, nationwide rose from 3.11% (36 367/1 167 807) in 1990 to 4.12% (25 431/617 725) in 2021. The LTBI age-standardized infection rate exhibited a fluctuating declining trend, averaging a decrease of 0.09%. Predictions for 2022-2030 indicate that China's multidrug-resistant TB incidence will decline slowly, and the LTBI infection rate will initially rise and then gradually fall, reaching 1.10/100 000 and 31.11%, respectively, by 2030.Conclusions:The TB burden in China declined from 1990 to 2021, but TB prevalence and LTBI infection rates remain high, especially among multidrug-resistant cases, males, and the elderly. Implementing systematic LTBI interventions, enhancing early detection/diagnosis in key populations such as the elderly, and promoting short-course treatments are recommended.
