    背景:中药固本健脑叶方(GBJNY)在中医治疗学习记忆障碍和老年失眠方面有着悠久的历史。该配方来源于孙思淼的五剂补药。此外,现代药理学研究揭示了其改善认知障碍和改善睡眠-觉醒昼夜节律紊乱的能力。然而,其疗效的确切机制仍然难以捉摸。
    目的:目前的研究通过转录组测序和实验验证,探讨了GBJNY在阿尔茨海默病昼夜节律睡眠-觉醒障碍和认知功能障碍中的调节作用和可能的机制。
    方法:利用LC-MS/MS串联技术定性地辨别存在于GBJNY中的活性组分。APP/PS1小鼠接受GBJNY或褪黑素连续治疗3个月。利用Morris水迷宫(MWM)测试对小鼠的学习和记忆能力进行评估,同时利用脑电图(EEG)和肌电图(EMG)研究睡眠变化。同时,研究了小鼠海马时钟基因的节律性。随后,我们用HE染色,高尔基染色,和免疫荧光观察GBJNY对突触损伤和神经元丢失的影响。我们进行了高通量测序以分析小鼠的mRNA表达谱,旨在鉴定差异表达基因(DEGs)。随后,我们进行了GO和KEGG富集分析,以探索相关的信号通路。此外,我们评估了小鼠海马中PI3K/AKT/mTOR通路和Aβ沉积相关蛋白的表达水平。通过这种全面的方法,我们试图阐明和验证GBJNY在APP/PS1小鼠中的潜在作用机制.
    结果:结果显示216个DEG。在此之后,我们进行了GO富集和KEGG通路分析,以更深入地研究mRNA靶基因的区别和基本功能。富集分析强调了PI3K/Akt/mTOR信号通路作为其中最关键的信号通路的重要性。通过体内实验,进一步证明,给予GBJNY可增强APP/PS1小鼠的记忆和学习能力.此外,GBJNY治疗导致睡眠-觉醒昼夜节律的改变,其特征在于觉醒减少和非快速眼动(NREM)睡眠增加。此外,Per1、Per2、Clock、在处理的小鼠的海马中注意到Cry1、Cry2和Bmal1mRNA。特别值得注意的是观察到海马内淀粉样β(Aβ)沉积的减少,神经元突触完整性的改善,和mTOR的上调,Akt,海马区PI3K蛋白表达。这些发现强调了PI3K/Akt/mTOR信号通路在减轻睡眠-觉醒昼夜节律紊乱中的关键参与。
    结论:GBJNY增强了APP/PS1小鼠的认知能力,改变了时钟基因表达模式,减轻睡眠-觉醒昼夜节律中断。基本机制似乎与PI3K/Akt/mTOR通路调节有关,为潜在的临床应用奠定了基础。
    BACKGROUND: The Chinese formula Guben-Jiannao Ye (GBJNY) formula has a long history of usage in traditional Chinese medicine (TCM) for the treatment of learning and memory disorders as well as senile insomnia. This formulation is derived from Sun Simiao\'s five tonic pills. Furthermore, modern pharmacological investigations have revealed its ability to improve cognitive impairment and ameliorate sleep-wake circadian rhythm disorders. However, the precise mechanism underlying its efficacy remains elusive.
    OBJECTIVE: The current research explored the modulatory effects and possible mechanisms of GBJNY in circadian rhythm sleep-wake disorders and cognitive dysfunction in Alzheimer\'s disease using transcriptome sequencing and experimental validation.
    METHODS: The LC-MS/MS tandem technology was utilized to qualitatively discern the active components present in GBJNY. The APP/PS1 mice received continuous treatment with GBJNY or Melatonin for 3 months. The learning and memory abilities of mice were assessed utilizing the Morris water maze (MWM) test, while sleep changes were studied utilizing the electroencephalogram (EEG) and electromyogram (EMG). Concurrently, mice\'s hippocampus clock gene rhythmicity was investigated. Subsequently, we employed HE staining, Golgi staining, and immunofluorescence to observe GBJNY\'s impact on synaptic damage and neuronal loss. We performed high-throughput sequencing to analyze the mRNA expression profiles of mice, aiming to identify differentially expressed genes (DEGs). Subsequently, we conducted GO and KEGG enrichment analyses to explore associated signaling pathways. Furthermore, we evaluated the expression levels of proteins involved in the PI3K/AKT/mTOR pathway and Aβ deposition in the hippocampus of mice. Through this comprehensive approach, we sought to elucidate and validate the potential mechanisms of action of GBJNY in APP/PS1 mice.
    RESULTS: Results showed 216 DEGs. Following this, we conducted GO enrichment and KEGG pathway analyses to delve deeper into the distinctions and fundamental functions of the mRNA target genes. The enrichment analysis underscored the prominence of the PI3K/Akt/mTOR signaling pathway as the most pivotal among them. Through in vivo experiments, it was further demonstrated that the administration of GBJNY enhanced memory and learning capacities in APP/PS1 mice. Additionally, GBJNY treatment resulted in alterations in the sleep-wake circadian rhythm, characterized by reduced wakefulness and an increase in non-rapid eye movement (NREM) sleep. Moreover, alterations in the peak expression of Per1, Per2, Clock, Cry1, Cry2, and Bmal1 mRNA were noted in the hippocampus of treated mice. Particularly noteworthy were the observed reductions in amyloid-beta (Aβ) deposition within the hippocampus, improvements in neuronal synaptic integrity, and upregulation of mTOR, Akt, and PI3K protein expression in the hippocampal region. These findings underscore the critical involvement of the PI3K/Akt/mTOR signaling pathway in mitigating disturbances in sleep-wake circadian rhythms.
    CONCLUSIONS: GBJNY enhanced the cognitive performance of APP/PS1 mice and altered clock gene expression patterns, alleviating sleep-wake circadian rhythm disruptions. The fundamental mechanism appears to be linked to the PI3K/Akt/mTOR pathway regulation, offering a foundation for potential clinical applications.

    This study aimed to investigate the mechanism of action of myrrh in breast cancer (BC) treatment and identify its effective constituents. Data on the compounds and targets of myrrh were collected from the TCMSP, PubChem, and Swiss Target Prediction databases. BC-related targets were obtained from the Genecard database. A protein-protein interaction (PPI) analysis, gene ontology (GO) enrichment, and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis were conducted on the intersecting targets of the disease and drug. The key targets of myrrh in BC treatment were identified based on the PPI network. The active constituents of myrrh were determined through reverse-screening using the top 20 KEGG pathways. Macromolecular docking studies, molecular dynamic (MD) simulations, and cell assays were utilized to validate the active constituents and critical targets. Network pharmacology indicated that VEGFA, TP53, ESR1, EGFR, and AKT1 are key targets of myrrh. Pelargonidin chloride, Quercetin, and Naringenin were identified as the active constituents of myrrh. Macromolecular docking showed that Quercetin and Naringenin have strong docking capabilities with ESR1. The results of MD simulation experiments align with those of molecular docking experiments. Cell and western blot assays demonstrated that Quercetin and Naringenin could inhibit MCF-7 cells and significantly reduce the expression of ESR1 protein. The findings reveal the active constituents, key targets, and molecular mechanisms of myrrh in BC treatment, providing scientific evidence that supports the role of myrrh in BC therapy. Furthermore, the results suggest that network pharmacology predictions require experimental validation for reliability.

    牛皮癣是一种炎症性和持续性的皮肤病,导致高复发率,生活质量差,和重大的社会经济负担。其主要病理表现为T细胞异常活化浸润和角质形成细胞(KCs)过度增殖。绝大多数银屑病患者在缓解后会复发。它通常持续一生,需要长期的治疗策略。在活动和缓解期间,牛皮癣的主要细胞类型之一是记忆T细胞,其中包括组织驻留记忆T(TRM)细胞,中央记忆T(TCM)细胞,和效应记忆T(TEM)细胞。它们通过释放炎症因子起作用,细胞毒性颗粒,或者改变细胞亚群,导致炎症增加或复发。本文就记忆T细胞在银屑病病理及治疗中的作用作一综述。以寻找潜在的新疗法和治疗靶点。
    Psoriasis is a skin disease that is inflammatory and persistent, causing a high rate of recurrence, poor quality of life, and significant socioeconomic burden. Its main pathological manifestations are abnormal activation and infiltration of T cells and excessive proliferation of keratinocytes (KCs). The great majority of patients with psoriasis will relapse after remission. It usually lasts a lifetime and necessitates long-term treatment strategies. During periods of activity and remission, one of the main cell types in psoriasis is memory T cells, which include tissue-resident memory T (TRM) cells, central memory T (TCM) cells, and effector memory T (TEM) cells. They work by releasing inflammatory factors, cytotoxic particles, or altering cell subpopulations, leading to increased inflammation or recurrence. This review summarizes the role of memory T cells in the pathology and treatment of psoriasis, with a view to potential novel therapies and therapeutic targets.

    达尔湖,这个举世闻名的旅游胜地已经受到外来和本地来源的污染,结果,水体中的重金属(HMs)浓度已达到有毒水平,危及人们的生命。在2021年(i)期间进行了一项研究,以确定HMs的浓度(钼:钼,砷:Ar,镉:Cd,铅:铅)在达尔湖的四个指定地点,(ii)一项公众调查(400人),涉及就康乐用途和其他利益对水体进行经济评估。DalLake内生物需氧量(BOD)和化学需氧量(COD)的最高值记录在站点A,分别为31±1.10mg/l和76±0.64。同样,在A位点发现了最大的硝酸盐氮(865±0.86μg/l)。从站点A报告了Pb的最高值(6.828±0.003ppb),而B位点最低(2.492±0.002ppb)。发现Mo浓度的平均值(以ppb计)在四个位点分别为2.538±0.002、1.703±0.003、3.627±0.004和4.787±0.002。HMs的观测值(以ppb为单位)远高于允许值(世卫组织,2006年)和之前报道的那些。从达尔湖的浮动花园中产生了巨额资金(16,18,66,000卢比/),通过TCM和CVM方法计算。在调查期间,68%的人表示愿意为恢复达尔湖和改善服务付费(WTP)(平均值:62,852.20卢比/)。因此,除了水质恶化的可能原因外,还进行了监测和评估,以了解达尔湖如何通过其不同的服务和对游客的主要吸引力为国家经济做出贡献。以便为达尔湖的可持续保护找到持久的解决方案。
    Dal Lake, the world-famous tourist attraction has been polluted by allochthonous and autochthonous sources, as a result the heavy metal (HMs) concentrations within the water body has reached the toxic levels which is endangering the lives of the people. A study was carried out during the year 2021 (i) to determine the concentration of HMs (molybdenum: Mo, arsenic: Ar, cadmium: Cd, lead: Pb) at the four designated sites of Dal Lake, and (ii) a public survey (400 persons) involving economic valuation of water body in terms of recreational use and other benefits. The highest values of biological oxygen demand (BOD) and chemical oxygen demand (COD) within the Dal Lake were recorded at site A, which were 31 ± 1.10 mg/l and 76 ± 0.64, respectively. Similarly, maximum nitrate nitrogen was found at site A (865 ± 0.86 μg/l). The highest value of Pb was reported (6.828 ± 0.003 ppb) from site A whereas, the lowest from site B (2.492 ± 0.002 ppb). The mean values of Mo concentrations (in ppb) were found to be 2.538 ± 0.002, 1.703 ± 0.003, 3.627 ± 0.004 and 4.787 ± 0.002 at the four sites respectively. The observed values of HMs (in ppb) were much higher than the permissible values (WHO, 2006) and those reported earlier. A huge amount of money (Rs 16,18,66,000/) is being generated from the floating gardens of Dal Lake, calculated by TCM and CVM methods. During the survey, 68 % of people showed a willingness to pay (WTP) for the restoration of the Dal Lake and improved services (mean value: Rs 62,852.20/). Thus, the monitoring and assessment were done to find out how the Dal Lake contributes to the economy of the state by way of its different services and the major attraction for tourists besides the possible reasons for the deterioration of water quality, in order to find a long-lasting solution for the sustainable conservation of Dal Lake.

    王氏代谢配方(WMF)是在王坤根教授的指导下开发的中药配方。WMF已经在临床上使用了几年。然而,WMF治疗代谢相关脂肪性肝病(MAFLD)的机制尚不清楚.在这项研究中,我们使用LC-MS对WMF进行了植物化学分析。为了研究WMF在MAFLD中的作用,我们对高胆固醇高脂饮食(HCHFD)诱导的雄性MAFLD小鼠口服WMF(20.6g/kg)。然后是病态的,生物化学,并进行代谢组学分析。WMF的主要成分是绿原酸,栀子苷,albiflorin,芍药苷,和calycosin-7-O-葡萄糖苷。用WMF治疗的MAFLD小鼠在肥胖方面表现出显著改善,脂质代谢异常,炎症,和肝脏病理学。WMF降低天冬氨酸氨基转移酶(AST),丙氨酸氨基转移酶(ALT),MAFLD小鼠血清中的甘油三酯(TG)水平,同时增加高密度脂蛋白胆固醇(HDL-c)水平。WMF降低肝脏TG水平和炎症因子(IL-1β,IL-6,TNF-α,和NF-κB)。肝脏的代谢组学分析注释了富含四种途径的78种差异调节的代谢物:甘油磷脂代谢,视黄醇代谢,PPAR信号通路,和胆碱代谢。Westernblot实验显示WMF增加PPAR-α的表达,PPAR-β,和肝脏中的RXR,同时降低RAR的表达。该研究表明WMF对MAFLD具有坚实的预防和治疗作用。WMF的抗炎和调节异常肝脏代谢活性涉及视黄醇代谢和PPAR受体信号通路。
    Wang\'s metabolic formula (WMF) is a traditional Chinese medicine formula developed under the guidance of Professor Kungen Wang. WMF has been clinically utilized for several years. However, the therapeutic mechanism of WMF in treating metabolic-associated fatty liver disease (MAFLD) remains unclear. In this study, we performed phytochemical analysis on WMF using LC-MS. To study the role of WMF in MAFLD, we orally administered WMF (20.6 g/kg) to male MAFLD mice induced by a high-cholesterol high-fat diet (HCHFD). Then pathological, biochemical, and metabolomic analyses were performed. The main components of WMF are chlorogenic acid, geniposide, albiflorin, paeoniflorin, and calycosin-7-O-glucoside. MAFLD mice treated with WMF exhibited significant improvements in obesity, abnormal lipid metabolism, inflammation, and liver pathology. WMF decreased aspartate aminotransferase (AST), alanine aminotransferase (ALT), and triglyceride (TG) levels in the serum of MAFLD mice while increasing high-density lipoprotein cholesterol (HDL-c) levels. WMF lowered liver TG levels and inflammatory factors (IL-1β, IL-6, TNF-α, and NF-κB). Metabolomic analysis of the liver annotated 78 differentially regulated metabolites enriched in four pathways: glycerophospholipid metabolism, retinol metabolism, PPAR signaling pathway, and choline metabolism. Western blot experiments showed that WMF increased the expression of PPAR-α, PPAR-β, and RXR in the liver while decreasing the expression of RAR. The study demonstrates that WMF has a solid preventive and therapeutic effect on MAFLD. The anti-inflammatory and regulation of abnormal liver metabolism activities of WMF involve retinol metabolism and the PPAR signaling pathway.

    Citri Grandis Exocarpium (Huajuhong, CGE) is the peel of the unripe fruits of Citrus grandis \'Tomentosa\' and Citrus grandis (L.) Osbeck, which is commonly used in the clinic for the treatment of cough and indigestion. The pharmacological mechanism of CGE is unclear. In this study, the pharmacological effect of CGE was predicted by System Traditional Chinese Medicine (SYSTCM), which integrated the pharmacological effect prediction approach by artificial intelligence into the systemic traditional Chinese medicine (TCM) platform. The main pharmacological effect of CGE was antiallergy, promoting bile, blood lipid regulation, cardiotonics, diuresis, and antiarrhythmia by prediction of SYSTCM. In vitro cell experiments were carried out to identify the antiallergic effect of CGE. Extracts of Citri Grandis Exocarpium (ECGE) inhibited lipopolysaccharide-induced cell injury and nitric oxide release in RAW264.7 cells. ECGE and naringin-inhibited immunoglobulin E-induced cell degranulation in RBL-2H3 cells. Target profiling, protein interaction network, and molecular docking of compounds from CGE indicated that mitogen-activated protein kinase 14 (MAPK14) and matrix metalloprotease 9 (MMP9) were key potential targets of CGE with antiallergic activity. This study identified and validated the antiallergic effect of CGE by combining SYSTCM, cell experiments, and virtual screening, which provided a new paradigm and approach for studying the pharmacological effect and mechanism of TCM.

    对突破性医疗保健创新的追求导致了人工智能(AI)和中医(TCM)的融合,从而标志着一个新的领域,展示了将古代治疗方法的优势与现代技术的尖端进步相结合的前景。TCM,这是一个整体的医疗系统,拥有超过2000年的经验支持,使用独特的诊断方法,如检查,听诊和嗅觉,询问,和触诊。人工智能是通过机器模拟人类的智能过程,尤其是通过计算机系统。中医是以经验为导向的,整体,整体和主观的,它与人工智能的结合具有有益的效果,这可能源于诊断准确性的观点,治疗功效,和预后的准确性。人工智能在中医中的作用突出了它在诊断中的使用,机器学习通过复杂的模式识别提高治疗的精度。通过AI分析的舌头图像,中医辨证的准确性更高,可以证明这一点。然而,将人工智能整合到中医中也带来了多方面的挑战,例如数据质量和道德问题;因此,统一战略,例如使用标准化数据集,需要提高人工智能对中医原理的理解和应用。通过整合AI的中医发展是阐明医疗保健新视野的关键因素。随着研究的不断发展,技术专家和中医从业者必须合作推动创新解决方案,突破医学科学的界限,尊重中医的深刻遗产。我们可以绘制未来的课程,其中AI增强的中医实践有助于更系统,有效,和所有个人都可以使用的医疗保健系统。
    The pursuit of groundbreaking health care innovations has led to the convergence of artificial intelligence (AI) and traditional Chinese medicine (TCM), thus marking a new frontier that demonstrates the promise of combining the advantages of ancient healing practices with cutting-edge advancements in modern technology. TCM, which is a holistic medical system with >2000 years of empirical support, uses unique diagnostic methods such as inspection, auscultation and olfaction, inquiry, and palpation. AI is the simulation of human intelligence processes by machines, especially via computer systems. TCM is experience oriented, holistic, and subjective, and its combination with AI has beneficial effects, which presumably arises from the perspectives of diagnostic accuracy, treatment efficacy, and prognostic veracity. The role of AI in TCM is highlighted by its use in diagnostics, with machine learning enhancing the precision of treatment through complex pattern recognition. This is exemplified by the greater accuracy of TCM syndrome differentiation via tongue images that are analyzed by AI. However, integrating AI into TCM also presents multifaceted challenges, such as data quality and ethical issues; thus, a unified strategy, such as the use of standardized data sets, is required to improve AI understanding and application of TCM principles. The evolution of TCM through the integration of AI is a key factor for elucidating new horizons in health care. As research continues to evolve, it is imperative that technologists and TCM practitioners collaborate to drive innovative solutions that push the boundaries of medical science and honor the profound legacy of TCM. We can chart a future course wherein AI-augmented TCM practices contribute to more systematic, effective, and accessible health care systems for all individuals.

    背景:代谢综合征(MetS),以肥胖为特征,高血糖症,血脂水平异常,是许多心血管疾病的病理基础。瓜楼-谢白-半夏汤(GT)最早是在《金殿要略》中描述的,中国最早的中医杂病诊疗专著。根据中医戒律,基于它激活阳以释放停滞的能力,激活气以减少抑郁,去痰,扩大胸部,GT已被用于治疗心血管疾病超过2,000年。然而,其治疗机制的分子基础尚不清楚.
    目的:本研究的目的是鉴定由GT差异调节的与脂质和葡萄糖相关的肝脏基因,并评估GT对肠道菌群组成的影响,在高脂饮食(HFD)诱导的MetS小鼠中。
    方法:ApoE-/-小鼠用HFD喂养24周,有或没有同时补充GT,诱导MetS。在研究结束时,体重,内脏脂肪重量,血脂水平,测量胰岛素敏感性,组织病理学染色用于评估肝骨病和肠屏障的完整性。肝脏转录组学用于分析肝脏中差异表达的基因和相关调节途径的预测。通过RT-qPCR和蛋白质印迹法检测肝脂/糖代谢相关基因和蛋白。通过16SrRNA基因测序确定肠道微生物组成。
    结果:GT给药减少了与MetS相关的肝脏脂肪变性和体重增加,促进胰岛素敏感性和脂质代谢,并通过降低g_Lachnoshispileae_NK4A136_组的相对丰度和增加g_Alistipes的相对丰度来有益地调节肠道微生物群组成。肝脏转录组学显示,GT调节与脂质和葡萄糖代谢相关的基因的表达(Pparγ,Igf1,Gpnmb,和Trem2)以及编码趋化因子/趋化因子受体的基因(例如Cxcl9和Cx3cr1)。重要的,Ccr2,Ccl4,Ccr1和Cx3cr1与g_Lachnospiraceae_NK4A136_组呈正相关,在Cxcl9,Ccr2,Ccl4和Cx3cr1和g_脱硫弧菌之间。GT处理下调SCD1和CX3CR1的蛋白表达,上调PCK1蛋白表达。
    结论:补充GT通过改善肝脏脂质和葡萄糖代谢减轻HFD诱导的小鼠MetS。GT的抗代谢综合征作用可能与肠-肝轴的调节有关。
    BACKGROUND: Metabolic syndrome (MetS), characterized by obesity, hyperglycemia, and abnormal blood lipid levels, is the pathological basis of many cardiovascular diseases. Gualou-Xiebai-Banxia-Tang decoction (GT) was first described in the Synopsis of the Golden Chamber, the earliest traditional Chinese medicine (TCM) monograph on diagnosis and treatment of miscellaneous diseases in China. According to TCM precepts, based on its ability to activate yang to release stagnation, activate qi to reduce depression, remove phlegm, and broaden the chest, GT has been used for more than 2,000 years to treat cardiovascular ailments. However, the molecular bases of its therapeutic mechanisms remain unclear.
    OBJECTIVE: The aim of this study was to identify lipid- and glucose-related hepatic genes differentially regulated by GT, and to assess GT impact on gut microbiota composition, in mice with high-fat diet (HFD)-induced MetS.
    METHODS: ApoE-/- mice were fed with an HFD for 24 weeks, with or without concurrent GT supplementation, to induce MetS. At the study\'s end, body weight, visceral fat weight, blood lipid levels, and insulin sensitivity were measured, and histopathological staining was used to evaluate hepatosteatosis and intestinal barrier integrity. Liver transcriptomics was used for analysis of differentially expressed genes in liver and prediction of relevant regulatory pathways. Hepatic lipid/glucose metabolism-related genes and proteins were detected by RT-qPCR and western blotting. Gut microbial composition was determined by 16S rRNA gene sequencing.
    RESULTS: GT administration reduced MetS-related liver steatosis and weight gain, promoted insulin sensitivity and lipid metabolism, and beneficially modulated gut microbiota composition by decreasing the relative abundance of g_Lachnospiraceae_NK4A136_group and increasing the relative abundance of g_Alistipes. Liver transcriptomics revealed that GT regulated the expression of genes related to lipid and glucose metabolism (Pparγ, Igf1, Gpnmb, and Trem2) and of genes encoding chemokines/chemokine receptors (e.g. Cxcl9 and Cx3cr1). Significant, positive correlations were found for Ccr2, Ccl4, Ccr1, and Cx3cr1 and the g_Lachnospiraceae_NK4A136_group, and between Cxcl9, Ccr2, Ccl4, and Cx3cr1 and g_Desulfovibrio. GT treatment downregulated the protein expressions of SCD1 and CX3CR1 and upregulated the expression of PCK1 protein.
    CONCLUSIONS: GT supplementation alleviates HFD-induced MetS in mice by improving hepatic lipid and glucose metabolism. The anti-metabolic syndrome effects of GT may be related to the regulation of the gut-liver axis.

    BACKGROUND: Tinnitus diagnosis poses a challenge in otolaryngology owing to an extremely complex pathogenesis, lack of effective objectification methods, and factor-affected diagnosis. There is currently a lack of explainable auxiliary diagnostic tools for tinnitus in clinical practice.
    OBJECTIVE: This study aims to develop a diagnostic model using an explainable artificial intelligence (AI) method to address the issue of low accuracy in tinnitus diagnosis.
    METHODS: In this study, a knowledge graph-based tinnitus diagnostic method was developed by combining clinical medical knowledge with electronic medical records. Electronic medical record data from 1267 patients were integrated with traditional Chinese clinical medical knowledge to construct a tinnitus knowledge graph. Subsequently, weights were introduced, which measured patient similarity in the knowledge graph based on mutual information values. Finally, a collaborative neighbor algorithm was proposed, which scored patient similarity to obtain the recommended diagnosis. We conducted 2 group experiments and 1 case derivation to explore the effectiveness of our models and compared the models with state-of-the-art graph algorithms and other explainable machine learning models.
    RESULTS: The experimental results indicate that the method achieved 99.4% accuracy, 98.5% sensitivity, 99.6% specificity, 98.7% precision, 98.6% F1-score, and 99% area under the receiver operating characteristic curve for the inference of 5 tinnitus subtypes among 253 test patients. Additionally, it demonstrated good interpretability. The topological structure of knowledge graphs provides transparency that can explain the reasons for the similarity between patients.
    CONCLUSIONS: This method provides doctors with a reliable and explainable diagnostic tool that is expected to improve tinnitus diagnosis accuracy.
