Objective: To develop a non-invasive predictive model for coronary artery stenosis severity based on adaptive multi-modal integration of traditional Chinese and western medicine data. Methods: Clinical indicators, echocardiographic data, traditional Chinese medicine (TCM) tongue manifestations, and facial features were collected from patients who underwent coronary computed tomography angiography (CTA) in the Cardiac Care Unit (CCU) of Shanghai Tenth People's Hospital between May 1, 2023 and May 1, 2024. An adaptive weighted multi-modal data fusion (AWMDF) model based on deep learning was constructed to predict the severity of coronary artery stenosis. The model was evaluated using metrics including accuracy, precision, recall, F1 score, and the area under the receiver operating characteristic (ROC) curve (AUC). Further performance assessment was conducted through comparisons with six ensemble machine learning methods, data ablation, model component ablation, and various decision-level fusion strategies. Results: A total of 158 patients were included in the study. The AWMDF model achieved excellent predictive performance (AUC = 0.973, accuracy = 0.937, precision = 0.937, recall = 0.929, and F1 score = 0.933). Compared with model ablation, data ablation experiments, and various traditional machine learning models, the AWMDF model demonstrated superior performance. Moreover, the adaptive weighting strategy outperformed alternative approaches, including simple weighting, averaging, voting, and fixed-weight schemes. Conclusion The AWMDF model demonstrates potential clinical value in the non-invasive prediction of coronary artery disease and could serve as a tool for clinical decision support.

ObjectiveThrough qualitatively and quantitatively analysis of the differences in chemical composition between the combined decoction and single decoction of Huaganjian and comparison of their core efficacy， to explore the rationality of the flexible clinical application of Huaganjian compound preparations and single-flavored dispensing granules. MethodsUltra performance liquid chromatography-quadrupole-electrostatic field orbitrap high resolution mass spectrometry（UPLC-Q-Exactive Orbitrap MS） was used to qualitatively analyze the combined decoction and single decoction samples of Huaganjian， and meanwhile， the contents of four index components（geniposide， paeoniflorin， hesperidin and paeonol） were quantitatively analyzed by high performance liquid chromatography（HPLC）. Nonalcoholic fatty liver disease（NAFLD） rat model induced by high-fat diet was applied to compare the efficacy of combined decoction and single decoction of Huaganjian. A total of 30 male SD rats were randomly divided into the control group， model group， lovastatin group（1.8 mg·kg^-1）， combined decoction group（1.26 g·kg^-1） and single decoction group（1.18 g·kg^-1）. After successful modeling， lovastatin group， combined decoction group and single decoction group were given corresponding doses of drugs by intragastric administration every day， and the control group and model group were given equal amounts of normal saline by intragastric administration， after 4 weeks of administration， the serum and liver tissues were collected， and the contents of alanine aminotransferase（ALT）， aspartate aminotransferase（AST）， total cholesterol（TC）， triglyceride（TG）， low-density lipoprotein cholesterol（LDL-C） and high-density lipoprotein cholesterol（HDL-C） in serum of rats were detected， and the liver pathological examination was carried out by hematoxylin-eosin（HE） staining and oil red O staining， so as to compare differences of their efficacy. ResultsSeventy chemical components were initially identified and attributed from the lyophilized powder of the combined decoction and single decoction samples of Huaganjian， and there was no obvious difference in composition between the two. Further quantitative analysis showed that the contents of geniposide， paeoniflorin， hesperidin and paeonol in the combined decoction samples were significantly increased when compared with those of the single decoction samples（P<0.01）. The pharmacodynamic results showed that compared with the model group， both the combined and single decoction groups of Huaganjian could improve the liver index of NAFLD rats， reduce the serum levels of AST， ALT， TC， TG and LDL-C， increase the serum level of HDL-C， and ameliorate the pathological changes of liver cell steatosis and fat accumulation. However， there was no significant difference in pharmacodynamic effects between the combined decoction group and the single decoction group. ConclusionThere is no significant difference between the combined decoction and single decoction of Huaganjian in terms of chemical composition， but the contents of the four index components show significantly difference. Both of them can significantly improve the fat accumulation and liver function in NAFLD rats. This study provides a reference basis for the rational clinical application and evaluation of famous classical formula compound preparations and single-flavored dispensing granules.

Neurodegenerative diseases(NDD)are a heterogeneous group of disorders characterized by neuronal degeneration and functional impairment,in which neuroinflammation plays a pivotal role throughout disease onset and progression.The 18 kDa translocator protein(TSPO)serves as an important molecular biomarker of neuroinflammation,with its expression closely associated with activation of microglia and astrocytes.TSPO-PET enables noninvasive and dynamic mapping of spatiotemporal distribution of cerebral neuroinflammation,providing crucial molecular imaging evidence for early diagnosis,disease evaluation and therapeutic response assessment of NDD.The advances and challenges of TSPO-PET imaging in NDD were reviewed in this article.

AIM:To investigate the potential mechanism of licorice on liver injury induced by Se-men Strychni based on network pharmacology,mo-lecular docking combined with animal experiments,providing an effective strategy for prevention and treatment of liver injury induced by Semen Strych-ni.METHODS:Firstly,the active ingredients of Se-men Strychni and licorice were obtained through the ETCM,TCMSP database and analysis platform,CTD database and literature supplementation.Then,the potential toxic ingredients of Semen Strychni were further screened based on the Swis-sADME platform,and the targets corresponding to the active ingredients were predicted through the SwissTargetPrediction platform.By using the Gene-Cards and OMIM databases to collect DILI-related targets,the potential targets for licorice to alleviate liver injury caused by Semen Strychni were ob-tained.By constructing the active ingredient-target network,the core ingredients of licorice in alleviat-ing liver injury caused by Semen Strychni were screened.The key targets obtained were used to construct and analyze the protein-protein interac-tion networks(PPI)through the STRING database and Cytoscape 3.9.0 software.The potential targets were subjected to GO and KEGG pathway enrich-ment analysis with the aid of the DAVID database,and constructed a network of active ingredient-tar-get-pathway.Molecular docking study was ap-proved for the core targets and the active ingredi-ents by using Schrodinger 2023-1 software,and the visualization operation was conducted through Py-mol.Finally,the regulatory effect of licorice on the key pathway of liver injury caused by Semen Strych-ni was validated by establishing a rat model of liver injury induced by Semen Strychni.RESULTS:After screening,6 potential toxic components of Semen Strychni and 104 corresponding targets,89 active components of licorice and 347 corresponding tar-gets,and 3 200 DILI targets were obtained.A total of 23 intersection targets were obtained through Venn analysis.By constructing the active ingredi-ent-target network,it was found that the main core ingredients were 7-methoxy-2-methyl isofla-vone,medicarpin,shinpterocarpin,quercetin,for-mononetin and isoliquiritigenin.The PPI network indicated that the core targets were protein kinase B1(AKT1),epidermal growth factor receptor(EG-FR),human epidermal growth factor receptor 2(ERBB2),glycogen synthase kinase 3 beta(GSK3B),kinase insert domain receptor(KDR)and Janus ki-nase 2(JAK2).A total of 39 relevant pathways were enriched in KEGG(P＜0.01),among which the phos-phatidylinositol 3-kinase(PI3K)-protein kinase B(AKT)(PI3K-AKT)signaling pathway,which has been confirmed and ranks first in enrichment,and was closely related to liver injury.Molecular docking re-sults showed that the core components have good binding ability with the core targets.In vivo animal experiments demonstrated that,compared to the model group,licorice significantly reduced the liver index(P＜0.01),serum levels of alkaline phospha-tase(ALP),alanine aminotransferase(ALT),aspar-tate aminotransferase(AST),indirect bilirubin(IBIL),and total bilirubin(TBIL)in rats with liver in-jury,while increasing total protein(TP)levels(P＜0.05 or P＜0.01).Additionally,licorice alleviated con-gestion in the central veins and hepatic sinusoids,improved the alignment of hepatocytes,and re-duced inflammatory cell infiltration.Furthermore,licorice significantly decreased the levels of malo-ndialdehyde(MDA),tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β),and interleukin-6(IL-6)in the liver tissue of injured rats,while elevating the levels of superoxide dismutase(SOD)and glutathi-one peroxidase(GSH-Px)(P＜0.01).It also markedly downregulated the phosphorylation levels of PI3K and AKT(P＜0.01).CONCLUSION:Licorice has multi-component and multi-target properties in the treat-ment of liver injury induced by Semen Strychni,which may play a hepatoprotective role by inhibit-ing the activation of PI3K-AKT signaling pathway.

OBJECTIVE To understand the surveillance data regarding to prevalence of hospital-associated infections(HAIs)in a three-A children's specialized hospital of Henan Province and analyze the change trends so as to pro-vide bases for developing precise prevention strategies and optimizing the allocation of infection control resources.METHODS The data involving the case information,case-time infection rates,infection sites,distribu-tion of departments and pathogens were collected from the children who were hospitalized in Children's Hospital Affiliated to Zhengzhou University from 2020 to 2024.The statistical analysis was performed by SPSS 25.0 soft-ware.RESULTS A total of 460,516 children who were hospitalized for treatment from 2020 to 2024,3700 of whom had hospital-associated infections,with the incidence of HAIs 0.80％;totally 3907 case-times of children had HAIs,with the case-time infection rate 0.85％.The departments ranking the top 5 incidence rates of HAIs were as follows:hematopoietic stem cell transplantation ward,ward 2 of hemooncology department,ward 1 of hemooncology department,ward of rehabilitation center,neonatal surgery department.The lower respiratory tract was the major infection site,accounting for 41.13％.The children who had respiratory system infections accounted for 65.29％.The gram-negative bacteria were dominant among the pathogens causing the HAIs,accounting for 48.15％;the percentage of viruses showed an upward trend.CONCLUSIONS The incidence of HAIs shows fluctu-ating downward trend.It is necessary to further strengthen the refined management and take targeted infection prevention and control measures for the departments at high risk of HAIs and the high-risk links so as to continu-ously improve the medical quality and safety.

Objective To explore the expression of serine/threonine protein kinase 1(AKT1)and Isocho-rismatase Domain-Containing 1(ISOC1)in gastric cancer tissues and evaluate their diagnostic utility.Methods A total of 90 patients with gastric cancer who were diagnosed and treated in our hospital between March 2023 and September 2024 were recruited as the study subjects.The positive expression rates and positive scores of AKT1 and ISOC1 in cancer tissues and adjacent tissues were compared.The AKT1 and ISOC1 positive scores of gastric cancer patients with diverse characteristics were also compared.The Spearman correlation analysis was employed to exam-ine the relationship between the expression of AKT1 and ISOC1 in cancer tissues and the clinical features of gastric cancer patients.A diagnostic model for gastric cancer,integrating AKT1 and ISOC1,was established using the Logistic regression model.Receiver operating characteristic(ROC)curves were plotted to analyze the area under the curve(AUC)value,sensitivity,and specificity of AKT1,ISOC1,and their combined diagnosis for gastric cancer.Results The positive expression rates and positive scores of AKT1 and ISOC1 in cancer tissues were significantly higher than those in paracancerous tissues(P<0.05).In gastric cancer patients,the expressions of AKT1 and ISOC1 were notably higher in patients with low differentiation,clinical stage Ⅰ～Ⅱ,invasion depth T1-2,absence of lymph node metastasis,and no distant metastasis compared to those with moderate differentiation,clinical stage Ⅲ～Ⅳ,invasion depth T3-4,and presence of lymph node metastasis and distant metastasis(P<0.05).Spearman's correlation analysis indicated that AKT1 and ISOC1 were positively correlated with the degree of differ-entiation,clinical stage,lymph node metastasis,invasion degree,and distant metastasis(P<0.05).The area under the curve(AUC)values of AKT1,ISOC1,and their combined diagnosis for gastric cancer were 0.735,0.726,and 0.875 respectively(P<0.05).The sensitivities were 60.00%,56.70%,and 75.60%,while the speci-ficities were 85.60%,83.30%,and 87.80%.The AUC value of the combined detection of AKT1 and ISOC1 in the diagnosis of gastric cancer was higher than that of AKT1 or ISOC1 alone(Z=-3.003,-3.196,P<0.05).Conclusions AKT1 and ISOC1 are highly expressed in gastric cancer tissues,and their expressions are upregu-lated with the progression of the disease.The combined detection of their expression levels holds great significance for the diagnosis and prognosis assessment of gastric cancer.

Musculoskeletal disorders (MSDs) are characterized by extensive pathological involvement and high prevalence and cause a significant disease burden. Long-term drug administration often causes by adverse effects with poor therapeutic efficacy. Low-intensity pulsed ultrasound (LIPUS), as a specialized therapeutic modality, delivers acoustic energy at a low intensity in a pulsed wave mode, thus ensuring stable energy transmission to the target tissues while minimizing thermal effects. This non-invasive approach has demonstrated significant potential for MSD treatment by delivering effective physical stimulations. Extensive animal and clinical studies have demonstrated the efficacy of LIPUS for accelerating the healing process of fresh fractures and nonunions, promoting soft tissue regeneration and suppressing inflammatory responses. Emerging evidence suggests promising applications of LIPUS in skeletal muscle injury treatment and promoting tissue regeneration and repair. This review outlines the recent advancements and mechanistic studies of LIPUS for treatment of common MSDs including fractures, nonunions, muscle injuries, and osteoarthritis, addressing also the technical parameters of commercially available LIPUS devices, current therapeutic approaches, the existing challenges, and future research directions.
