In the context of the rapid development of 5G technology， the development of artificial intelligence （AI） in traditional Chinese medicine （TCM） faces new opportunities and challenges. Focusing on how to uphold tradition while innovating in the development of AI in TCM， starting from the current development status of AI in Chinese medicine， including the integration of four diagnostic methods， syndrome differentiation and treatment， auxiliary diagnosis and treatment， research and development of Chinese herbal medicine， prevention and treatment of diseases， knowledge inheritance， and other aspects， this paper discussed the support of policies and technical advancements， as well as development opportunities such as increased demand for health. Regarding machine ethics， data ethics， regulatory review， and other aspects， it also proposed some suggestions that the training algorithm should be improved to assist medical work； data ownership should be clarified to ensure data security； and an AI ethics committee should be set up to improve the review system， aiming to maximize the advantages of smart healthcare and accelerate the modernization of TCM for the benefit of patients and the service of human health.

ObjectiveTo investigate the effects of Maxing Kugan decoction （MKD） on inflammatory response and apoptosis in rats with oleic acid （OA）-induced acute lung injury （ALI） and explore its mechanism of action. MethodsSixty Sprague-Dawley （SD） rats were randomly assigned into six groups： a control group， a model group， a dexamethasone-treated group （2 mg·kg^-1）， and three MKD-treated groups at low， medium， and high doses （3.1， 6.2，12.4 g·kg^-1）. Each group was administered either an equivalent volume of normal saline or the corresponding concentration of MKD by gavage for seven consecutive days. The model group and each administration group were used to establish the ALI model by tail vein injection of OA （0.2 mL·kg^-1）. Twelve hours after modeling， blood gas analyses were conducted， and the wet-to-dry （W/D） weight ratio of lung tissue was measured for each group. Additionally， enzyme-linked immunosorbent assay （ELISA） was employed to quantify the levels of tumor necrosis factor-alpha （TNF-α）， interleukin-1β （IL-1β）， and interleukin-6 （IL-6） in the bronchoalveolar lavage fluid （BALF） of the rats. Cell damage and apoptosis in lung tissue were examined via hematoxylin-eosin （HE） staining and TdT-mediated dUTP-biotin nick end labeling （TUNEL） assays， and the results were subsequently scored. The expression levels of the p38 mitogen-activated protein kinase （p38 MAPK）/nuclear factor kappa-B （NF-κB） signaling pathway and apoptosis-related proteins and mRNAs were assessed using Western blot and real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. ResultsCompared with the control group， the model group exhibited a significant decrease in partial pressure of oxygen （PaO₂）， blood oxygen saturation （SaO₂）， and oxygenation index （PaO₂/FiO₂）， along with a marked increase in partial pressure of carbon dioxide （PaCO₂） and lung W/D ratio （P<0.01）. Additionally， levels of TNF-α， IL-6， and IL-1β in BALF were significantly elevated （P<0.01）. Histopathological analysis of lung tissue showed significant inflammatory infiltration， tissue edema， alveolar septal thickening， and apoptosis of lung tissue. Pronounced increases were observed in the mRNA expression levels of p38 MAPK， NF-κB p65， inhibitor of NF-κB （IκBα）， B-cell lymphoma-2 associated x protein （Bax）， and Caspases-3， as well as the protein expression levels of p-p38 MAPK， p-NF-κB p65， p-IκBα， Bax， Caspases-3， and cleaved Caspases-3， while the mRNA and protein expression of Bcl-2 was downregulated （P<0.01）. Compared with the model group， MKD significantly elevated PaO₂， SaO₂， and PaO₂/FiO₂ while reducing PaCO₂ and W/D ratio in rats （P<0.01）. It also greatly reduced TNF-α， IL-6， and IL-1β levels in BALF （P<0.01） and alleviated inflammatory infiltration， tissue edema， alveolar septal thickening， and apoptosis of lung tissue. Additionally， it downregulated the mRNA expression of p38 MAPK， NF-κB p65， IκBα， Bax， Caspases-3， as well as protein expression of p-p38 MAPK， p-NF-κB p65， p-IκBα， Bax， Caspases-3， and cleaved Caspases-3 in lung tissue （P<0.05， P<0.01）， while significantly upregulating mRNA and protein expression of Bcl-2 （P<0.01）. ConclusionMKD exerts a protective effect on OA-induced ALI rats， potentially through the regulation of the p38 MAPK/NF-κB signaling pathway to inhibit inflammation and apoptosis.

Objective : To investigate the antidepressant effects and the underlying mechanisms of tetrahydrocurcumin(THC) and its nanoparticle formulation(THCN). Methods : Forty-six male ICR mice were randomly divided into Con group, LPS group, THC group, THCN group and SER group. A mouse depression model was established by intraperitoneal administration of LPS. The anxiety and depression-like behaviors of mice were evaluated by open field test(OFT) and forced swimming test(FST). Myelin staining was applied to assess the extent of demyelination in the prefrontal cortex of the mice. The prefrontal cortex and hippocampus were further examined for the expression levels of glial fibrillary acidic protein(GFAP) and Toll-like receptor 4(TLR4) through quantitative immunofluorescence assays. Results : Compared with the Con group, the LPS group showed increased anxiety-like and depressive-like behaviors in both the long-term and short-term experiments(P<0.05); the degree of demyelination increased in the LPS group of the long-term experiment(P<0.01); the expression of GFAP was reduced in the LPS group of the short-term experiment(P<0.01), while the expression of TLR4 increased(P<0.05); the expression of TLR4 decreased in the THC group(P<0.01); the expression of GFAP in the prefrontal cortex of the THCN group was reduced(P<0.01), while the expression of TLR4 increased(P<0.05). Compared with the LPS group, the THC group showed reduced depressive-like behaviors in the long-term experiment(P<0.05), while the anxiety-like and depressive-like behaviors of the THCN group and the SER group were reduced(P<0.05), and the anxiety-like and depressive-like behaviors of the THC group and the THCN group were reduced in the short-term experiment(P<0.05); the degree of demyelination was reduced in the THC group, THCN group and SER group in the long-term experiment(P<0.05); the expression of GFAP increased in the THC group of the short-term experiment(P<0.05), while the expression of TLR4 was reduced(P<0.05), and the expression of GFAP increased in the THCN group(P<0.05). Compared with the THC group, the THCN group and the SER group showed reduced anxiety-like behaviors in the long-term experiment(P<0.05); the expression of GFAP in the prefrontal cortex of the THCN group was reduced in the short-term experiment(P<0.05), while the expression of TLR4 in the hippocampal DG area increased in the short-term experiment(P<0.01). Conclusion Tetrahydrocurcumin and its nanoparticle formulation both exert significant ameliorative effects on depression-like behaviors and demyelination in mice induced by lipopolysaccharide. The antidepressant mechanism of THC appears to be mediated through the down-regulation of TLR4 and the up-regulation of GFAP. The mechanism underlying the antidepressant action of THCN seems predominantly focused on the enhancement of GFAP expression.

Objective : To investigate the therapeutic effects and underlying mechanisms of cannabidiol(CBD) and its nano-formulations on depression-like behaviors in mice. Methods : A murine model of acute anxiety and depression was established by intraperitoneal administration of lipopolysaccharide(LPS). A total of 55 mice were randomly assigned into several groups: for the long-term study, a control group(Con), a model group(LPS), a cannabidiol group(CBD), a nano-cannabidiol group(NCBD), and a sertraline(SER) group, each consisting of 7 mice. In the short-term study, mice were divided into four groups: the Con group, LPS group, CBD group, and NCBD group, with 5 mice in each group. Except for the Con group and LPS group, which were given distilled water, the remaining groups were administered 25 and 50 mg/kg of cannabidiol and its nano-formulationviaoral gavage. The open field and forced swimming tests were employed to assess anxiety-and depression-like behaviors inmice. Luxol Fast Blue myelin staining was employed to evaluate myelin sheath morphology in the prefrontal cortex, and immunofluorescence staining was utilized to quantify the protein expression levels of silencing information regulator(SIRT2), ionized calcium binding adaptor molecule-1(Iba-1), and interleukin-1β(IL-1β) in the prefrontal cortex. Results : In the long-term experiment, the LPS group exhibited a significant reduction in shuttle times(P<0.05), an increase in immobility time(P<0.01), and a decrease in the number and length of myelin sheaths(P<0.05) compared to the Con group. Compared to the LPS group, the depressive behaviors in the CBD, NCBD, and SER groups were significantly alleviated(P<0.01), and the number and length of myelin sheaths increased(P<0.05). In the short-term experiment, compared to the Con group, the LPS group exhibited significantly increased anxiety-and depression-like behaviors(P<0.05), downregulated SIRT2 expression(P<0.01), and upregulated Iba-1 and IL-1β expression(P<0.01). The CBD and NCBD groups demonstrated a reduction in anxiety and depression-like behaviors(P<0.05), an increase in SIRT2 expression(P<0.01), and a decrease in Iba-1 and IL-1β expressions(P<0.05) compared to the LPS group. Conclusion CBD and its nano-formulations effectively mitigate anxiety and depression-like behaviors in mice. The underlying mechanisms may be associated with the reversal of SIRT2 protein expression, demyelination changes, microglial activation, and the levels of inflammatory factors in the prefrontal cortex.

Objective To observe the changes in the subfoveal choroidal thickness(SFCT)of children and adoles-cents with different refractive states using optical coherence tomography angiography.Methods A total of 171 children and adolescents were followed.They were divided into the lower primary school group(6-8 years old),upper primary school group(9-11 years old),and junior high school group(12-14 years old)according to their age at the time of en-rollment.Dioptric examinations(including best corrected visual acuity,diopter,intraocular pressure,corneal curvature,axial length and SFCT)were performed,data collection was conducted twice in half a year(initial examination and review after half a year),and the eyeball parameters and changes in eyeball parameters after half a year among all groups were compared.Results The axial length and SFCT of subjects had significant differences among all groups(both P＜0.05).In children and adolescents,the axial length gradually lengthened and SFCT gradually thickened with age,while intraocular pressure and corneal curvature were not associated with age(both P＞0.05).In the initial examination and review after half a year,there was no significant difference in intraocular pressure,corneal curvature and SFCT of subjects with differ-ent refractive states in all groups(all P＞0.05),while the axial length of myopic subjects was greater than that of non-my-opic subjects in all groups(all P＜0.05).In the review after half a year,the SFCT of non-myopic subjects in the lower pri-mary school group and upper primary school group was significantly thickened(P＜0.001,P=0.003),while there was no significant difference in SFCT of myopic subjects in all groups compared with the value half a year ago(all P＞0.05).The axial length of all subjects showed a positive correlation with the SFCT in the initial examination and review after half a year(r=0.354,0.228,P＜0.05).Conclusion Myopia affects the increase in SFCT in children and adolescents.

Objective:To investigate the relationship between the lowest hemoglobin value during hospitalization and the prognosis in patients with extensive burns, in order to explore the hemoglobin warning threshold for blood transfusion in patients with extensive burns.Methods:The research was a retrospective observational study. From October 2012 to October 2022, 288 patients with extensive burns who met the inclusion criteria were admitted to the First Affiliated Hospital of Army Medical University (the Third Military Medical University), including 243 males and 45 females, aged 18 to 65 years. These patients were assigned to the death group ( n=54) and the survival group ( n=234) based on their final prognosis. The clinical data including gender, age, body mass index, total burn area, full-thickness burn area, time of first operation after injury, preoperative prothrombin time (PT) and activated partial thromboplastin time (APTT) and hemoglobin level of the first surgery, complication of inhalation injury, number of surgeries, total surgical area, total surgical time, total length of hospital stay, and highest procalcitonin value, lowest platelet count and hemoglobin values, and occurrence of sepsis during hospitalization were compared between the two groups of patients. According to the lowest hemoglobin value during hospitalization, the patients were assigned to <65 g/L group, ≥65 g/L and <75 g/L group, ≥75 g/L and <85 g/L group, and ≥85 g/L group. The total length of hospital stay, mortality and incidence of sepsis during hospitalization, and mortality within 90 days after injury were compared among the four groups of patients. The relationship between the lowest hemoglobin value during hospitalization and the mortality risk of patients with extensive burns was analyzed using a restricted cubic spline model before and after adjusting covariates. A logistic regression model was adopted to analyze the relationship between the lowest hemoglobin value during hospitalization and the mortality risk of patients with extensive burns after adjusting covariates, with the lowest hemoglobin value during hospitalization as a continuous variable and a categorical variable, separately. Results:Compared with those in survival group, the total burn area, full-thickness burn area, and total surgical area of patients in death group were significantly increased, the preoperative APTT of the first surgery was significantly prolonged, the number of surgeries was significantly reduced, the total length of hospital stay was significantly shortened, the highest procalcitonin value during hospitalization was significantly increased, the lowest platelet count and hemoglobin values during hospitalization were significantly decreased, and the incidence proportion of sepsis during hospitalization was significantly increased (with Z values of -6.72, -5.40, -2.15, -2.99, -2.21, -7.84, -6.23, -7.03, and -3.43, respectively, χ2=161.95, P values all <0.05). There were no statistically significant differences in the other clinical data of patients between the two groups ( P>0.05). There were statistically significant differences in mortality and incidence of sepsis during hospitalization, and mortality within 90 days after injury of patients among the four groups divided according to the lowest hemoglobin value during hospitalization (with χ2 values of 12.12, 15.93, and 10.62, respectively, P<0.05). There was no statistically significant difference in the total length of hospital stay of patients among the four groups ( P>0.05). The restricted cubic spline model analysis revealed an approximately linear relationship between the lowest hemoglobin value during hospitalization and the mortality risk of patients with extensive burns before and after adjusting covariates (with χ2 values of 0.81 and 0.75, respectively, P>0.05). After adjusting covariates, the logistic regression model analysis showed that the mortality risk of patients with extensive burns increased with decreasing hemoglobin when the lowest hemoglobin value during hospitalization was analyzed as a continuous variable (with odds ratio of 0.96, with 95% confidence interval of 0.92 to 0.99, P<0.05). When using the median value of 75.5 g/L as the cut-off value for categorizing the lowest hemoglobin value during hospitalization, there was no statistically significant difference in the mortality risk between patients with hemoglobin <75.5 g/L and those with hemoglobin ≥75.5 g/L ( P>0.05). When the patients were divided into four groups based on the lowest hemoglobin value during hospitalization as above, using ≥85 g/L group as a reference, only patients in <65 g/L group had a significantly increased mortality risk (with odds ratio of 5.37, with 95% confidence interval of 1.57 to 18.29, P<0.05). Conclusions:There is an approximately linear correlation between the lowest hemoglobin value during hospitalization and the mortality risk of patients with extensive burns. When the hemoglobin level drops to 65 g/L or lower, the mortality risk of patients increases significantly, suggesting that a hemoglobin level of 65 g/L could serve as a warning threshold for blood transfusion in patients with extensive burns.

Objective In the context of expanding in size and improving the quality of medical consumables,the"one product,one policy"approach has brought challenges to the management of consumables in public hospitals.This study investi-gated the potential management problems in the process of centralized procurement with volume of medical consumables in a pub-lic tertiary hospital in Guangdong Province,and accordingly worked out the corresponding management countermeasures and then assessed their implementation effects.Methods The fishbone diagrams was applied to systematically analyze the potential prob-lems in the implementation process of centralized procurement with volume of medical consumables.Targeted measures were worked out from May to July 2023 in the hospital.The time series data of centralized procurement of coronary stents,pacemak-ers,tubular/end-to-end anastomoses,and spinal products from December 2022 to December 2023 were analyzed.Changes in the monthly implementation rate and contract completion volume pre-and post-intervention were measured to evaluate the effectiveness of the intervention.Results The fishbone diagrams analysis revealed that the primary factors impeding procurement implementa-tion were internal system flaws,personnel management inadequacy,supply issues,and an absence of an information system.Post-intervention,the monthly implementation rate(t=-4.19,P＜0.05)and contract completion(t=-2.38,P＜0.05)significantly improved.Conclusion The implementation of intervention management for centralized procurement with volume of medical consumables can effectively promote the related implementation effect in the department.In the context of centralized pro-curement,clinical and health management personnel need to bolster their professionalism to ensure the procurement management efficiency and quality.It is crucial to deepen policy understanding and implementation,enhance production and distribution process supervision and disciplinary mechanisms,ensure multi-departmental coordination for supply security,and improve hospi-tal information systems and procurement platforms.

Effective cost control and structure optimization of medical consumables in public hospitals can facilitate a shift from extensive cost control to scientific and refine management.On the premise of ensuring medical quality,reducing the burden of patients'diagnosis and treatment and meeting the actual needs of hospital management,this approach aims to realize valuable healthcare outcomes.This study was conducted in a tertiary hospital,which balanced both the medical and economic val-ue of medical consumables.Using an integrated approach to specialty capacity building and disease structure optimization,the hospital restructured the use of medical consumables in Transcatheter Arterial Embolization(TAE)procedures.It developed standardized pathways and usage protocols tailored to specific diseases and surgical requirements.A targeted consumable usage policy framework was introduced,comprising"one department,one policy;one surgery type,one policy;and one consumable,one policy."This included initiatives such as validating the use of drug-loaded embolic microspheres,conducting multi-depart-mental review meetings,strictly regulating indications for these microspheres,limiting personnel involvement,and negotiating re-duced pricing on imported microspheres.Following implementation,the average case-mix index(CMI)for discharged patients undergoing TAE increased from 2.23 to 2.34(P＜0.001),while the average per-case cost of consumables decreased from 19 600 to 15 600(P＜0.001).These measures offer valuable decision-making and operational reference for hospitals nation-wide,supporting efficient,quality-focused consumables management.
