ObjectiveThe essence of syndrome manifestation recognition in traditional Chinese medicine (TCM) is to infer the body’s latent pathogenesis state from clinical observational information, rather than to perform simple label matching. However, previous studies have largely modeled this task as syndrome pattern classification within a fixed label space, which does not adequately reflect the cognition process of TCM syndrome differentiation centered on pathogenesis reasoning, and is also insufficient to capture the openness, semantic variability, and cross-disease reusability of syndrome manifestation expression. This study aimed to investigate whether introducing pathogenesis reasoning chain-of-thought (PR-CoT) supervision into large language models (LLMs) could improve the quality and cognitive consistency of syndrome manifestation recognition and support cross-disease transfer. MethodsSyndrome manifestation recognition was formulated as a conditional generation task under the framework of clinical observational information (X)→pathogenesis structure (Z)→syndrome pattern output (Y), where Z serves as an explicit intermediate structural variable linking the clinical evidence and syndrome judgment. Within this framework, a PR-CoT-supervised dataset for syndrome manifestation recognition was constructed based on medical case records of spleen-stomach disorders. After preprocessing, information extraction, manual proofreading, and data cleaning, the dataset comprised 4 800 training cases, 400 development cases, and 400 test cases. Each sample was annotated with a structured PR-CoT consisting of three progressive levels: clinical information summarization, comprehensive pathogenesis analysis, and syndrome pattern output. Supervised fine-tuning was conducted on open-source LLMs, with an end-to-end model serving as the baseline. Qwen3-32B was used as the primary experimental model, and Qwen3-14B as the scale comparison model. A progressive multidimensional evaluation framework was further established, comprising a structural parsing level, a semantic similarity level, and an expert blind review level. At the structural parsing level, syndrome pattern expressions were decomposed into structural elements and evaluated using Precision, Recall, F1 score, and Jaccard similarity. At the semantic similarity level, independent LLMs scored the theoretical proximity between predicted and reference syndrome patterns. At the expert blind review level, three TCM experts independently evaluated model outputs on two dimensions: syndrome differentiation consistency and terminology standardization of syndrome patterns. In addition, zero-shot cross-disease transfer evaluation was conducted on gynecological and heart-system disorder test sets. ResultsAt the structural parsing level, PR-CoT supervision did not lead to a stable improvement in the element-wise overlap of syndrome pattern structural components. Compared with the corresponding baselines, neither Qwen3-32B nor Qwen3-14B showed consistent advantages in structural matching metrics after the introduction of PR-CoT supervision. In contrast, at the semantic similarity level, PR-CoT supervision produced stable positive gains across different model scales and evaluation systems. The average semantic score of Qwen3-32B increased from 6.425 8 in the baseline model to 6.585 0 after PR-CoT supervision, and that of Qwen3-14B increased from 5.870 0 to 5.964 2. At the expert blind review level, the overall score of Qwen3-32B (PR-CoT) was 7.026 0±0.107 7, higher than 6.416 3±0.288 9 for its baseline. In zero-shot cross-disease testing, the PR-CoT model still showed advantages in semantic evaluation and expert evaluation on both gynecological and heart-system disorder test sets, indicating a certain degree of transferability. ConclusionThe benefits of PR-CoT supervision are mainly reflected in TCM semantic consistency and clinical plausibility, rather than in improved hard matching of structural elements. These findings support understanding syndrome manifestation recognition as a process of generating and expressing latent pathogenesis structures, rather than as a classification task within a traditional fixed label space. By introducing pathogenesis reasoning as an explicit intermediate structure into the modeling process and combining it with a progressive multidimensional evaluation framework, this study provides a methodological pathway for intelligent TCM syndrome differentiation that integrates theoretical alignment, interpretability, and multi-level evaluation.

Objective: To identify early clinical predictors associated with dysphagia and delayed swallowing recovery in patients with traumatic brain injury (TBI). Methods: In this retrospective study, we enrolled adult TBI patients admitted to the rehabilitation unit of a tertiary medical center between June 2019 and June 2023. Data on baseline characteristics, neurological status, imaging findings, and rehabilitation-related variables were collected. Swallowing function was assessed using two indicators: (1) nasogastric (NG) tube retention and (2) the Functional Oral Intake Scale (FOIS) scores at 1, 4, and 12 weeks post-injury. Regression analyses were conducted to identify predictors associated with dysphagia and swallowing recovery. Results: A total of 160 patients were included. At 1 week post-injury, longer intensive care unit (ICU) stay, poor initial sitting balance and use of sedative medication in ICU were associated with NG tube retention. At 4 weeks, lower initial Rancho Los Amigos Scale (RLAS) scores, immobility-related complications, longer hospitalization, and temporal lobe hematomas were associated with persistent NG tube dependence. By 12 weeks, older age, delayed ability to follow commands, and poor initial sitting balance remained associated with NG tube retention. FOIS outcomes were also associated with older age, delayed time to follow commands, impaired initial sitting balance, prolonged ICU stay, temporal lobe hematomas, lower initial RLAS scores, immobility-related complications, prolonged endotracheal tube placement and extended hospital stays. Conclusion Impaired cognitive status, poor physical function, immobility-related complications, and temporal lobe hematomas were key factors associated with dysphagia and delayed oral intake in individuals with TBI.

Objective To investigate the epidemiological characteristics of malaria and provide a basis for developing improved prevention and control measures. Methods Data were obtained from the Chinese Disease Prevention and Control Information System. Malaria surveillance data for Nanning City from January 1,2023, to December 31,2024, were exported from the Infectious Disease Reporting Information Management Subsystem. The characteristics of the two groups of malaria cases were compared. Results A total of 103 imported malaria cases were reported in Nanning City in 2024, representing a 38.32% decrease compared with the same period of the previous year. No statistically significant difference were observed between cases reported in 2023 and 2024 in terms of average age, gender ratio, proportion of parasite species, and monthly reporting distribution;however, statistically significant differences were found in the proportion of reporting areas and current residence areas(χ2= 13.572 and 10.355, respectively; P = 0.001 and 0.035, respectively). The proportion of cases reported in Shanglin County and the proportion of cases residing in Shanglin County were both lower than those during the same period of the previous year. Conclusions The high aggregation of imported malaria cases in Nanning City has decreased. Medical institutions in areas other than Shanglin County should strengthen their vigilance against malaria.

Objective To gain insights into the biological characteristics of different populations of Culex tritaeniorhynchus within and around the Yellow Sea wetland from the perspective of the occurrence of resistance, we investigated the levels of resistance to deltamethrin and kdr gene mutation in the wetland and its peripheral areas. Methods Specimens were collected from Cx. tritaeniorhynchus populations at two monitoring sites in the Rare Bird National Nature Reserve and Tiaozi Ni Wetland Scenic Area, and also from two populations in Yancheng City and the Liuhe District of Nanjing, and the resistance of these mosquitoes to deltamethrin was determined using the CDC biotest bottle method. For each concentration of deltamethrin assessed, a random subset of exposed specimens was selected for amplification of the kdr gene fragment, followed by Sanger sequencing to identify and analyze resistance-associated mutations. Results The LC50 levels of deltamethrin among mosquitoes from the four populations in Luhe, Yancheng, the Rare Bird National Nature Reserve and the Tiaozi Ni Wetland Scenic Area were 2.048 5, 7.798 2, 3.473 3, and 17.695 5 mg/mL, respectively, with corresponding concentrations of deltamethrin ranging from 0.005 to 5.000,0.050 to 50.000,0.050 to 25.000 and 0.050 to 50.000 mg/mL, respectively. Furthermore, the ranges of the KT50 values were 11.76-107.43, 67.05-216.30,29.77-107.43 and 28.40-329.51 min; the 1-h knockdown rates were 34.58%-99.15%, 9.52%-43.80%, 55.09%-73.01%, and 10.09%-68.07%; and the 24-h mortality rates were 12.15%-67.52%,9.52%-79.56%,13.17%-82.21%, and 11.01%-78.99%, respectively. With respect to kdr gene mutation, we assayed a total of 63,70,59, and 57 mosquitoes for the four populations, for which we detected L1014F mutation frequencies of 14.29%, 35.00%, 20.34%, and 31.58%, respectively, with a majority of these mutations being heterozygous for resistance. In addition, five adult mosquitoes were identified has having synonymous mutations at site 1011[i. e. , AAT(asparagine)mutation to AAC(asparagine)]. Conclusions Our findings revealed the clear resistance of Cx. tritaeniorhynchus to deltamethrin in the Yancheng region of the Yellow Sea wetland, and the resistance phenotype and kdr frequency of Cx. tritaeniorhynchus in the wetland environment were comparable to those of Cx. tritaeniorhynchus in the wetland environment, thereby indicating that the resistance of different populations of Cx. tritaeniorhynchus was homogeneous under the pressure of different insecticide selection within and around the wetland. However, the underlying mechanisms need to be further studied.

Objective:To investigate mental health literacy and advance care planning(ACP)condition,their influencing fac-tors,and their correlation in elderly patients with coronary heart disease(CHD).Methods:General data of 500 elderly CHD patients admitted in the Second Affiliated Hospital of Chinese PLA Air Force Military Medical University between January 2020 and December 2021 were collected.Mental health literacy and ACP condition were assessed.Multivariate linear regres-sion was used to analyze their influencing factors,and Pearson method was used to analyze their association.Results:Total score of Multicomponent Mental Health Literacy(MHL)was(10.78±2.57)points,and total score of Advance Care Plan-ning Readiness Scale(ACPRS)was(71.41±4.84)points in the 500 elderly CHD patients.Multivariate linear regression a-nalysis indicated that level of disease uncertainty had negative impact on MHL score,presence of spouse and trust in medical care had positive impact on MHL score(P＜0.05 or＜0.01);number of complications had negative impact on ACPR score,while presence of spouse and family mean monthly income had positive impact on ACPRS score(P＜0.05 or＜0.01).Pearson correlation analysis indicated that MHL score was positively correlated with ACPRS score(r=0.476,P＜0.001).Conclusion:Both mental health literacy and ACP status need to be improved in elderly CHD patients.They are posi-tively correlated with each other.Presence of spouse,number of complications and trust in medical care are the important influencing factors.Therefore,medical staff can take targeted measures to improve ACP readiness and mental health quality.

Objective:This study aims to explore the rehabilitation effect of continuous rehabilitation management based on Internet thinking on patients with coronary heart disease(CHD)after percutaneous coronary intervention(PCI).Methods:This randomized controlled study enrolled 100 CHD patients admitted in Second Affiliated Hospi-tal of Chinese PLA Air Force Military Medical University between October 2020 and December 2021.They were di-vided into control group(n=50)and intervention group(n=50).Patients in control group received routine reha-bilitation nursing mode,compared to those in intervention group applying"Internet+"continuous rehabilitation nursing intervention program,both groups were intervened for 3 months.Cardiac function,cardiopulmonary exer-cise test indexes,depression,medication compliance,quality of life and incidence of adverse cardiovascular events within 1-year follow-up were compared between two groups.Results:Compared with patients in control group after 3 months,those in intervention group had significant higher oxygen uptake at anaerobic threshold(VO2@AT)[(11.75±0.39)ml·kg-1·min-1 vs.(10.17±0.76)ml·kg-1·min-1],peak oxygen uptake(Peak VO2)[(17.87±0.72)ml·kg-1·min-1 vs.(16.66±0.24)ml·kg-1·min-1],left ventricular ejection fraction(LVEF)[(51.15±2.42)％vs.(44.09±1.94)％],scores of Morisky Medication Adherence Scale(MMAS-8)[(5.29±0.30)points vs.(4.11±0.27)points]and Seattle Angina Questionnaire(SAQ)[(85.50±4.37)points vs.(73.27±2.53)points],and significant lower left ventricular end-diastolic diameter(LVEDd)[(40.51±0.41)mm vs.(46.64±0.99)mm],score of Patient Health Questionnaire-9(PHQ-9)[(7.67±0.85)points vs.(9.66±1.43)points]and total incidence of adverse cardiovascular events within 1-year follow-up(4.00％vs.16.00％)(P＜0.05 or＜0.01).Conclusion:Internet continuous rehabilitation intervention could improve car-diopulmonary exercise capacity and cardiac function,help to improve their quality of life and relieve depression,and reduce the risk of adverse cardiovascular events in CHD patients after PCI.

Objective:To analyze the dual gain effect of hyperbaric oxygen combined with vestibular rehabilitation training on patients with tinnitus and dizziness.Methods:This study was a retrospective analysis,and 90 patients with tinnitus and dizziness who visited the outpatient department of our hospital from January 2022 to January 2025 were selected to carry out the study,and were divided into observation group and control group according to the treatment methods,with 45 cases in each group.The matched group patients were treated with conventional medication,while the observation group received hyperbaric oxygen combined with vestibular rehabilitation training on the basis of the matched group.The clinical efficacy of the two groups was compared,including the concentration of oxygenated hemoglobin in the cerebral cortex,vestibular function,severity of tinnitus,and severity of dizziness before and after treatment.Results:The total effective rate of the observation group was higher than the matched group(P＜0.05);Post-treatment,there was no significant change in the concentration of oxygenated hemoglobin in the parietal and occipital cortex between the two groups(P＞0.05).However,the concentration of oxygenated hemoglobin in the temporal lobe,dorsolateral prefrontal cortex,and frontal polar cortex increased,and the observation group was higher than the matched group(P＜0.05);Post-treatment,the values of hemiparesis,total area of center of gravity movement(CA),and total length of center of gravity movement(PL)in both groups decreased,and the observation group was lower than the matched group(P＜0.05);Post-treatment,the severity score of tinnitus in both groups decreased,and the observation group was lower than that in the matched group(P＜0.05);Post-treatment,the degree score of vertigo in both groups decreased,and the observation group was lower than that in the matched group(P＜0.05).Conclusion:Hyperbaric oxygen combined with vestibular rehabilitation training has a significant dual gain effect on patients with tinnitus and dizziness,which can improve clinical efficacy,promote cortical neural activity,improve vestibular function,and thereby alleviate the severity of tinnitus and dizziness.

The number of patients with eye diseases in China is enormous,and the negative effects of these conditions,such as impaired visual function,psychological burdens,and restricted social participation,are becoming increasingly severe.Due to the limited and unevenly distributed ophthalmic resources,and the significant limitations of traditional diagnostic and therapeutic approaches in terms of accuracy and efficiency,there is an urgent need for more sensitive and efficient modalities.With the rapid advancement of artificial intelligence technology,ophthalmic diagnosis has entered a new stage of intelligent transformation.Facial photos,as a noninvasive and convenient medium,show unique advantages in eye disease diagnosis.Artificial intelligence systems based on facial photo analysis have been applied to the screening and diagnosis of conditions such as myopia,strabismus,ptosis,and thyroid eye disease,showing promising results.This review introduces the workflow of intelligent diagnosis for ocular diseases based on facial photographs,with a focus on recapitulating relevant research findings both domestically and internationally in recent years.It summarizes the innovative features and application advantages of intelligent diagnosis systems for eye diseases based on facial photos,analyzes the current technical bottlenecks and challenges in application,proposes corresponding countermeasures,and discusses future development directions,aiming to provide references and new insights for the intelligent screening and diagnosis of eye diseases.

The scientific research and innovation capabilities of medical students are intrinsically linked to the sustained and high-quality development of national healthcare initiatives.Cultivating outstanding medi-cal students with independent scientific capabilities and innovative consciousness is a critical component in the education and training of high-level medical professionals.Our investigation revealed that within the imperfections of the cultivating model,some faculty and students at medical schools have an insufficient understanding of scientific research and innovation and lack motivation for engaging in such activities,which hinder the progression of scientific research activities.Consequently,we initiated a teaching practice and exploratory study on the"tutorial system"aimed at fostering medical students'scientific research and innovation abilities.Based on the principle of"research informing teaching,teaching and research advan-cing together,"this study implements a"tutorial system"coordinated by tutors,supplemented by graduate and undergraduate student mentors,to cultivate innovative thinking,stimulate interest in scientific re-search,and enhance practical and research skills among medical students.Through collaborative efforts within"scientific research innovation teams,"various educational methods—including preliminary re-search,in-class and extracurricular activities,intra-group and inter-group interactions,and theoretical and practical applications—are employed to improve and strengthen the cultivation of medical students'scientif-ic research and innovation abilities.This study aims to provide valuable references for optimizing medical education management systems and enhancing the quality of medical student training.
