Traditional Chinese medicine （TCM） diagnosis is a cognitive process where practitioners rely on their subjective clinical experience and clinical perception abilities to comprehensively integrate the four examinations and flexibly differentiate syndromes， embodying a simple humanistic concern for the state of life. The essential characteristics of the subjectivity and experience of TCM diagnosis determine that there is a threshold in the syndrome differentiation capability of the artificial intelligence （AI）-based TCM diagnostic systems， which refers to a critical point of capability in the process of simulating the syndrome differentiation thinking， due to its inability to replicate the subjective cognition， clinical perception， and humanistic care of the practitioners. Furthermore， this threshold encompasses both a technical threshold and a theoretical threshold. Based on the above analysis， four human-machine collaborative practice paths are proposed to balance the application of AI technology and the subjectivity of TCM syndrome differentiation， including clarifying the auxiliary diagnosis and treatment positioning of AI， optimizing algorithms to achieve technical adaptation， strengthening the cultivation of the practitioner's subjectivity， and promoting interdisciplinary cross-collaboration， aiming to provide theoretical references for the development of AI-based TCM diagnostic systems towards human-machine collaborative clinical applications.

Adolescent idiopathic scoliosis(AIS)is a complex three-dimensional deformity involving coronal,sagittal,and axial planes,with a prevalence that should not be overlooked.With advancements in technology and in-depth research,an increasing number of hospitals and physicians are exploring standardized diagnostic and treatment approaches for AIS.Comprehensive and in-depth understanding is required for AIS,including its etiology,screening and diagnosis,classification,assessment and examination,treatment options,exploration of current focus,and evaluation of quality of life.Such understanding ensures that the diagnostic and treatment are scientific,standardized,and timely.Based on the principles of evidence-based medicine,a consensus on the diagnosis and treatment of AIS is reached after multiple discussions among spinal surgery experts,aiming to provide reference and guidance for clinical practice.

As the defining characteristic and essence of traditional Chinese medicine(TCM),the integration of disease and syndrome,along with the correlation between syndrome and prescription,forms the foundation for syndrome differentiation and treatment,and guides the clinical diagnosis and treatment practice of TCM.However,key scientific questions remain unresolved regarding the"disease-syndrome-prescription"framework,particularly the biological basis of diseases and syndromes,the active pharmacodynamic constituents of compound formulas,and their mechanism of action.Furthermore,a systematic paradigm for investigating"disease-syndrome-prescription"relationships has not been established,restricting the innovation and development of TCM theory and practice.Xiaoyao Powder,which was first described in a medical book named Taiping Huimin Heji Ju Fang written during the Song Dynasty of China,disperses stagnated liver qi for relieving qi stagnation,thus nourishing the blood and strengthening the spleen,making it a representative prescription for addressing depression due to liver qi stagnation and spleen deficiency under the guidance of correspondence between syndrome and prescription.Therefore,base on the combination of disease and syndrome,and correspondence between syndrome and prescription,investigating the formula-syndrome scientific connotation of Xiaoyao Powder and exploring the research paradigm for the"disease-syndrome-prescription"can provide insights into TCM theory from the perspective of modern science.

As a major global public health concern,the incidence of depression disorder is increasing annually.The pathological mechanism of depression involves bidirectional dysregulation between the hypothalamic-pituitary-adrenal(HPA)and gut-brain axes.According to traditional Chinese medicine(TCM),the liver controls conveyance and dispersion,the spleen governs transportation and transformation,and both jointly maintain the balance between ascending and descending qi movement and zang fu viscera function in the body.Liver qi stagnation and spleen deficiency result in qi movement disorder and a lack of source qi and blood,leading to depression induced by malnutrition of heart spirit.As a classic prescription for soothing the liver,invigorating the spleen,and replenishing blood,Xiaoyao Powder is used to reinforce healthy qi and eliminate pathogenic factors.Xiaoyao Powder not only regulates the"yin in property of liver"but also strengthens the"ascending and descending"of the spleen.As commonly used by ancient and modern physicians,also indirectly inhibits HPA axis upregulation and improves depression-related gastrointestinal dysfunction.This paper systematically expounds the multi-dimensional mechanism of Xiaoyao Powder in treating depression through the two-way regulation of the HPA-gut-brain axis.It reveals the therapeutic characteristics of"multi-component and multi-target"in TCM to provide a novel theoretical basis for the modernization of TCM and the treatment of depression by combining TCM and Western medicine.

Depression is closely associated with a neuro-endocrine-immune(NEI)system imbalance.The"excessive vitality leading to restraint and counter-regulation(Kang Hai Cheng Zhi)"theory elucidates the self-regulating mechanism for maintaining dynamic equilibrium in the body,and serves as an importance principle guiding treatment formulation and medication selection.Based on the correlation between NEI system imbalance and the traditional Chinese medicine pathogenesis of depression,and integrating the"Kang Hai Cheng Zhi"theory,the author posits that the pathogenesis of depression lies in overactive liver invading spleen,earth dampness impeding wood′s ascendancy,and disharmony between body and mind,as well as imbalance in storage and discharge functions of liver and kidney,disharmony between Yin and Yang,and disrupted counter-regulation.This dosely aligns with two key pathological methanisms at the micro level:microglial-limbic system homeostatic imbalance and hypothalamic-pituitary-adrenal axis-inflammatory circuit dysregulation.Clinically,the treatment principle for depression adheres to supporting the counter-regulation to restrain excess,with herbal interventions using strategies such as restraining wood to support earth,dredging earth to unblock wood,and harmonizing pivotal functions,as well as nourishing water to nurture wood,warming kidney to tonify liver,and relieving depression to calm the spirit.These approaches aim to regulate the liver,spleen,and kidney,embodying the core therapeutic tenet of"striving for equilibrium,"thereby restoring the body′s self-regulating capability.

Objective To observe the clinical efficacy of therapy focusing on regulating spleen and stomach for the treatment of acoustic hypersensitivity(AH),which also named as auditory hyperaesthesia,and to explore the relevant factors influencing the efficacy.Methods From January 2018 to December 2023,the patients admitted to the outpatient department of otolaryngology-head and neck surgery of the First Affiliated Hospital of Guangzhou University of Chinese Medicine and diagnosed as AH with complete medical data were included as study subjects.Follow-up through telephone or network was carried out for those patients who with uncertain prognosis.The changes in the pre-and post-treatment scores of Indicators of Acoustic Hypersensitivity Severity(IAHS)were used as the reference index for efficacy evaluation,and the cure rate and effective rate were used as the efficacy analysis indexes for statistical analysis.And then the efficacy of traditional Chinese medicine(TCM)medical care combined with health care focusing on regulating spleen and stomach for the treatment of AH was evaluated.Furthermore,multivariate logistic regression was used to explore the relevant factors influencing the efficacy of AH.Results A total of 298 cases of AH patients meeting the inclusion criteria were collected,among which 151 cases(50.67%)were cured,22 cases(7.38%)were markedly effective,75 cases(25.17%)were effective,and 50 cases(16.78%)were ineffective,with a total effective rate of 83.22%(248/298).The univariate analysis results showed that eight factors(including post-treatment lifestyle score,range of lifestyle adjustment,severity of AH,duration of the disease,presence of tinnitus,presence of hearing drop,presence of vertigo,and age)had an influence on the efficacy,and the differences were statistically significant(P<0.05 or P<0.01).However,the factors of gender,occupation,education level,and history of noise exposure had no influence on the efficacy(P>0.05).The multivariate binary logistic regression analysis showed that five factors,namely post-treatment lifestyle score,range of lifestyle adjustment,severity of AH,presence of vertigo and duration of the disease,had a significant correlation with the cure rate of AH(P<0.05 or P<0.01),and four factors,namely post-treatment lifestyle score,severity of AH,range of lifestyle adjustment and age,had a significant correlation with the effective rate of AH(P<0.05 or P<0.01).Conclusion The method of TCM medical care and health care focusing on regulating spleen and stomach exerts a better efficacy for AH patients.And the lifestyle,severity of AH,duration of the disease,age,and presence of vertigo are the relevant factors affecting the outcomes,which is worthy of further in-depth study.

OBJECTIVE To analyze the characteristics of imported malaria cases in West China Hospital of Sichuan University in recent years and to provide reference for the prevention and control of imported infectious diseases.METHOD A retrospective analysis of 62 cases of imported malaria from abroad reported in West China Hospital of Sichuan University from 2012 to 2023 were retrospectively analyzed.RESULTS From 2012 to 2023,62 cases of imported malaria were reported,including 49 cases(79.03％)of falciparum malaria,10 cases(16.13％)of vivax malaria,and 3 cases(4.84％)of ovale malaria.Among the imported malaria cases,9 cases were severe malaria,with 8(16.33％,8/49)severe cases caused by falciparum malaria,of which 6 cases(75.00％,6/8)were cere-bral malaria.The cases were mainly Chinese citizens and young-to-middle-aged adults,with the highest concentra-tion in the 40-49 age group(37.10％,23/62).There were more males than females,with a male-to-female sex ratio of 11.4∶1;the predominant occupation was worker(38.71％,24/62).The primary region of importation was Africa(90.32％,56/62).There was importation throughout the year,with no distinct seasonal distribution pattern.Two of the admitted cases died(severe cases of falciparum malaria,which developed into cerebral malari-a),while the rest were improved and discharged from the hospital after standardized treatment.CONCLUSIONS Cases of imported malaria from abroad are characterized by Chinese nationality,males,young adults and workers.The type of malaria is mainly falciparum malaria,and the prognosis for most cases is relatively good.It is necessary to strengthen the construction of joint prevention and control systems and other long-term mechanisms,and to continuously and scientifically implement various strategies and measures to prevent the re-emergence of malaria through imported ca-ses,in order to avoid the occurrence of secondary cases resulting from imported infections.

Donors with a serum sodium concentration of >155 mmol/L are extended criteria donors for liver transplantation (LT). Elevated serum sodium of donors leads to an increased incidence of hepatic dysfunction in the early postoperative period of LT; however, the exact mechanism has not been reported. We constructed a Lewis rat model of 70% hepatic parenchymal area subjected to ischemia-reperfusion (I/R) with hypernatremia and a BRL-3A cell model of hypoxia-reoxygenation (H/R) with high-sodium (HS) culture medium precondition. To determine the degree of injury, biochemical analysis, histological analysis, and oxidative stress and apoptosis detection were performed. We applied specific inhibitors of the epithelial sodium channel (ENaC) and Na⁺/Ca²⁺ exchanger (NCX) in vivo and in vitro to verify their roles in injury. Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), and lactate dehydrogenase (LDH) levels and the area of hepatic necrosis were significantly elevated in the HS+I/R group. Increased reactive oxygen species (ROS) production, myeloperoxidase (MPO)‍-positive cells, and aggravated cellular apoptosis were detected in the HS+I/R group. The HS+H/R group of BRL-3A cells showed significantly increased cellular apoptosis and ROS production compared to the H/R group. The application of amiloride (Amil), a specific inhibitor of ENaC, reduced ischemia-reperfusion injury (IRI) aggravated by HS both in vivo and in vitro, as evidenced by decreased serum transaminases, inflammatory cytokines, apoptosis, and oxidative stress. SN-6, a specific inhibitor of NCX, had a similar effect to Amil. In summary, hypernatremia aggravates hepatic IRI, which can be attenuated by pharmacological inhibition of ENaC or NCX.

OBJECTIVES: To evaluate the inhibitory effect of oridonin against proliferation of pancreatic cancer cells and the mechanism underlying the synergistic effect of low-intensity pulsed ultrasound (LIPUS). METHODS: PANC-1 cells treated with different concentrations of oridonin were examined for changes in cell proliferation using CCK-8 assay and in MDA, GSH and ATP levels using flow cytometry. The protein expressions of GPX4, Nrf2 and HO-1 in the treated cells were detected with Western blotting. The effect of Fer-1, a ferroptosis inhibitor, on proliferation of oridonin-treated cells were assessed, and the effects of oridonin combined with LIPUS on PIEZO1 protein expression was evalauted using Western blotting. A C57BL/6J mouse model bearing pancreatic cancer cell xenograft was established and treated with oridonin, LIPUS, or both, and the histological changes in the tumor tissues and tumor cell proliferation were examined with HE staining and immunohistochemistry for Ki67; the changes in GPX4 expression in the tumor tissues were detected using Western blotting and immunofluorescence staining. RESULTS: In PANC-1 cells, oridonin treatment significantly inhibited cell proliferation, increased intracellular Fe²⁺, ROS, and MDA levels, and decreased GSH and ATP levels. Oridonin also resulted in lowered GPX4 and increased HO-1 and Nrf2 protein expression levels in the cells. The combined treatment with LIPUS signficiantly enhanced the inhibitory effect of oridonin on PANC-1 cell viability in vitro and on xenograft growth in the mouse models, resulting also in more obvious reduction of the intensity of Ki67 staining and GPX4 protein expression and more pronounced increase of PIEZO1 protein expression in the tumor tissues in the mouse models. CONCLUSIONS LIPUS enhances the effect of oridonin to promote ferroptosis of pancreatic cancer cells by activating PIEZO1 through the Nrf2/HO-1/GPX4 pathway.
