Objective To explore the traditional Chinese medicine(TCM)syndrome characteristics of patients with Chikungunya hemorrhagic fever and to provide empirical data to support the application of TCM in diagnosing and treating Chikungunya hemorrhagic fever.Methods A cross-sectional survey was conducted to collect clinical data(sex,age,days since onset,and comorbidity underlying disease conditions)and TCM with four-examination information(symptoms,tongue manifestations,and pulse manifestations)from 255 patients with Chikungunya hemorrhagic fever who visited Lecong Hospital of Shunde,Foshan,the Third People's Hospital of Shunde District of Foshan,Shunde Hospital of Southern Medical University Affiliated Chencun Hospital between July 23 and July 29,2025.Factor and cluster analyses were used to summarize TCM syndrome characteristics and analyze core pathogenesis in conjunction with clinical features.Results Among the 255 patients with Chikungunya hemorrhagic fever,131 were male and 124 were female,with a age of(49.05±17.93)years and a disease duration of(3.26±1.78)days.Among the four types of examination information in TCM,35 items exhibited a frequency exceeding 10%.The most prevalent symptoms were arthralgia(180 patients,70.59%),exanthem(153 patients,60.00%),fatigue(99 patients,38.82%),anhidrosis(98 patients,38.43%),pruritus(96 patients,37.65%),and fever(92 patients,36.08%).Tongue and pulse manifestations were primarily white fur(155 patients,60.78%),pink tongue(111 patients,43.53%),slippery pulse(143 patients,56.08%),and greasy fur(134 patients,52.53%).Patients with disease onset≤3 d had a higher incidence of arthralgia,fatigue,fever,aversion to cold,generalized muscle pain,aversion to wind,insomnia,headache,sweating,low-grade fever,poor appetite,loose stool,hyperhidrosis,and red tongue than those with disease onset≥4 d(P<0.05).Patients with disease onset≥4 d had a higher incidence of pink tongue and thick fur than those with disease onset≤3 d(P<0.05).The syndrome elements in patients with Chikungunya hemorrhagic fever predominantly manifested on the defensive exterior,with involvement of the sinew-bone joints,skin-muscle,and spleen.Pathogenic factors were primarily characterized by external winds,dampness,and heat.Factor and cluster analysis result indicated three TCM pathogenesis progression patterns:imbalance of the defensive exterior with wind-dampness conflict and heat transformation;dampness-heat flowing into muscles and meridians causing joint obstruction and qi blood stasis;and dampness-heat congelation resulting in qi mechanism obstruction,consumption of body fluids,and infiltration of the skin.Conclusion Patients with Chikungunya hemorrhagic fever primarily present with fever,joint pain,and rashes.In TCM,this condition falls under the category of"dampness-warmth"syndrome.Its etiology is attributed to pathogens,with transmission occurring through mosquito bites.The core pathogenesis of TCM is the invasion of the defensive exterior and dampness-toxic heat accumulation.The therapeutic principles focus on clearing heat pathogens,resolving dampness pathogens,dispersing wind pathogens,and promoting the resolution of rashes.

Large language models (LLMs) such as ChatGPT, Claude, Llama, and Qwen are emerging as transformative technologies for the diagnosis and treatment of various diseases. With their exceptional long-context reasoning capabilities, LLMs are proficient in clinically relevant tasks, particularly in medical text analysis and interactive dialogue. They can enhance diagnostic accuracy by processing vast amounts of patient data and medical literature and have demonstrated their utility in diagnosing common diseases and facilitating the identification of rare diseases by recognizing subtle patterns in symptoms and test results. Building on their image-recognition abilities, multimodal LLMs (MLLMs) show promising potential for diagnosis based on radiography, chest computed tomography (CT), electrocardiography (ECG), and common pathological images. These models can also assist in treatment planning by suggesting evidence-based interventions and improving clinical decision support systems through integrated analysis of patient records. Despite these promising developments, significant challenges persist regarding the use of LLMs in medicine, including concerns regarding algorithmic bias, the potential for hallucinations, and the need for rigorous clinical validation. Ethical considerations also underscore the importance of maintaining the function of supervision in clinical practice. This paper highlights the rapid advancements in research on the diagnostic and therapeutic applications of LLMs across different medical disciplines and emphasizes the importance of policymaking, ethical supervision, and multidisciplinary collaboration in promoting more effective and safer clinical applications of LLMs. Future directions include the integration of proprietary clinical knowledge, the investigation of open-source and customized models, and the evaluation of real-time effects in clinical diagnosis and treatment practices.

AIM:This study aims to investigate the therapeutic effects of Xiaozhen Fang(XZF)on epidermal growth factor receptor(EGFR)inhibitor,erlotinib-induced skin toxicity in mice,with a focus on the underlying functional mechanisms.METHODS:A mouse model of skin toxicity was established and divided into three groups(n=5 per group):blank,erlotinib(150 mg/kg),and erlotinib(150 mg/kg)combined with XZF(45 g/kg)groups.Skin toxicity se-verity and body weight were evaluated.Western blot was performed to detect protein levels of gasdermin D(GSDMD),caspase-1,and interleukin-1β(IL-1β)in skin tissue.Immunofluorescence was employed to analyze gasdermin E,IL-1β,caspase-1,and nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3)expression in skin tissue.In vitro,HacaT cells were cultured and treated with erlotinib followed by different concentrations of XZF-containing se-rum.Cell viability was assessed by MTT assay.Cell ultrastructure was observed by transmission electron microscopy,and p53-binding protein 1(53BP1)expression was analyzed by immunofluorescence staining.RESULTS:The XZF signifi-cantly alleviated erlotinib-induced skin toxicity in mouse model,as evidenced by reduced rash incidence,alleviated limb swelling,and increased body weight(P<0.05).Expression of Gasdermins,IL-1β,caspase-1,and NLRP3 was distinctly down-regulated in dorsal skin tissue(P<0.05 or P<0.01).In vitro,XZF-containing serum markedly suppressed pyropto-sis in HacaT cells(P<0.01),preserved cell membrane integrity,and significantly reduced 53BP1 fluorescence intensity(P<0.01).CONCLUSION:The XZF mitigates EGFR inhibitor,erlotinib-induced skin toxicity in mice,potentially by regulating pyroptosis through the NLRP3/caspase-1/GSDMD signaling pathway.This mechanism exerts a cytoprotective ef-fect and alleviates erlotinib-induced skin toxicity.

Unlike chemosynthetic drugs designed for specific molecular and disease targets,active small-molecule natural products typically have a wide range of bioactivities and multiple targets,necessitating extensive screening and development.To address this issue,we propose a strategy for the direct in situ micro-dynamic examination of potential drug candidates to rapidly identify their effects and mechanisms of action.As a proof-of-concept,we investigated the behavior of mussel oligosaccharide(MOS-1)by tracking the subcellular dynamics of fluorescently labeled MOS-1 in cultured cells.We recorded the entire dynamic process of the localization of fluorescein isothiocyanate(FITC)-MOS-1 to the lysosomes and visualized the distribution of the drug within the cell.Remarkably,lysosomes containing FITC-MOS-1 actively recruited lipid droplets,leading to fusion events and increased cellular lipid consumption.These drug behaviors confirmed MOS-1 is a candidate for the treatment of lipid-related diseases.Furthermore,in a high-fat HepG2 cell model and in high-fat diet-fed apolipoprotein E(ApoE)-/-mice,MOS-1 significantly promoted triglyceride degradation,reduced lipid droplet accumulation,lowered serum triglyceride levels,and mitigated liver damage and steatosis.Overall,our work supports the prioritization of in situ visual monitoring of drug location and distribution in subcellular compartments during the drug development phase,as this methodology contributes to the rapid identification of drug indications.Collectively,this methodology is significant for the screening and development of selective small-molecule drugs,and is expected to expedite the identification of candidate molecules with me-dicinal effects.

The RANKL/RANK/OPG signaling pathway is essential for balancing bone resorption and bone formation. Research shows this signaling pathway exists in various tissues, including liver, muscle, adipose tissue, pancreas, and other tissues that might influence glucose metabolism. Blocking the pathway could protect islet β cell function. Furthermore, RANKL also improves insulin resistance by inducing beige adipocytes differentiation and increasing energy expenditure. Currently, the role of RANKL in glucose metabolism remains controversial. This article reviews current research and discusses the potential use of RANKL inhibitors for treating diabetes with osteoporosis.
