Traditional Chinese medicine(TCM)is an ancient medical system distinctive and effective in treating cancer,depression,coronavirus disease 2019(COVID-19),and other diseases.However,the relatively abstract diagnostic methods of TCM lack objective measurement,and the complex mechanisms of action are difficult to comprehend,which hinders the application and internationalization of TCM.Recently,while breakthroughs have been made in utilizing methods such as network pharmacology and virtual screening for TCM research,the rise of machine learning(ML)has significantly enhanced their inte-gration with TCM.This article introduces representative methodological cases in quality control,mechanism research,diagnosis,and treatment processes of TCM,revealing the potential applications of ML technology in TCM.Furthermore,the challenges faced by ML in TCM applications are summarized,and future directions are discussed.

Objective To explore the value of deep learning(DL)model based on grayscale ultrasound for predicting asymptomatic advanced chronic liver disease(cACLD).Methods Totally 258 patients with asymptomatic compensatory chronic liver diseases were retrospectively included,among them 117 with F3 or F4 stage liver fibrosis were classified into cACLD group,while 141 with F1 or F2 stage liver fibrosis were taken as non-cACLD group.The patients were divided into training set(n=180,including 82 cases of cACLD and 98 cases of non-cACLD)and validation set(n=78,including 35 cases of cACLD and 43 cases of non-cACLD)at the ratio of 7∶3.Univariate and multivariate logistic regression were used to screen independent clinical predictors of cACLD and construct a clinical model.Based on liver grayscale ultrasound,optimal DL features were extracted and screened,and Resnet50 network was adopted as framework,na?ve Bayes classifier was used to construct DL model,and a combined model was constructed based on clinical model and DL model.The efficacy and clinical value of each model for predicting asymptomatic cACLD were evaluated.Results Age,gamma-glutamyl transferase and platelet count were all independent clinical predictors of cACLD,and a clinical model was constructed.Totally 38 optimal DL features were screened to build a DL model.The AUC of combined model in training set and validation set was 0.950 and 0.740,of DL model was 0.944 and 0.737,respectively,being not significantly different(both P＞0.05)but all higher than that of clinical model(0.667 and 0.573,all P＜0.05).Taken 0.59-0.90 as the threshold,the net benefits of combined model in both training and validation sets were higher than that of other models.Conclusion DL model based on grayscale ultrasound could be used to effectively predict asymptomatic cACLD.Combining with clinical characteristics might improve clinical net benefit of this model.

Objective To investigate the drivers,stakeholders,core tasks,and differentiated development models of digital transformation in Chinese hospitals,develop a hospital digital transformation model,and propose advancement pathways.Methods Leveraging ROCCIPI theory,socio-technical systems theory,and social network theory,a multiple case study approach was employed to analyze four representative Chinese hospitals,examining the driving factors,social network relationship,and core tasks of digital transformation.Results Hospital digital transformation is a complex process driven by regulations,opportunities,and capabilities,requiring efficient collaboration among stakeholders focused on patient services,clinical operations,hospital management,and security.It identified three development models-ecology-oriented,regional integration,and grassroots enhancement—based on the distinct characteristics of the hospitals.A theoretical model for digital transformation in four Chinese hospitals was developed,along with proposed pathways and strategies.Conclusion It presents a digital transformation model and advancement pathways for hospitals through multiple case analyses,addressing the limited perspectives of existing research and providing a reference for practice.

Objective:To explore the construction of a core competency evaluation indicator system for pediatric surgery operating room specialist nurses.Methods:The evaluation indicator system was constructed by reviewing literature, analyzing semi-structured interview results, and examining the characteristics of training specialized nurses in pediatric surgery operating rooms, as well as combining the characteristics of pediatric surgery and multi-source data. The research group discussed and proposed a preliminary core competency evaluation indicator system for specialized nurses in pediatric surgery operating rooms. This study used the Delphi expert inquiry method to conduct two rounds of expert consultation and ultimately established the core competency evaluation indicator system for pediatric surgery operating room specialist nurses. The expert positivity coefficient was represented by the questionnaire response rate, and the expert authority coefficient was calculated using the judgment coefficient and familiarity degree. The coefficient of variation and Kendall's W coefficient were used to measure the degree of coordination of expert opinions. Results:The effective response rates for the two rounds of expert consultation were 100.00% and 95.24%, respectively. The authority coefficients of the two rounds of expert consultation were 0.92 and 0.90, respectively. The coefficients of variation of indicators at various levels were less than 0.25. The Kendall's W coefficients for the first-, second-, and third-level indicators in the first and second rounds of expert consultation were 0.516-0.664 and 0.652-0.711, respectively ( P<0.001). The final core competency evaluation indicator system for pediatric surgery operating room specialist nurses included 3 first-level indicators, 15 second-level indicators, and 52 third-level indicators. Conclusions:The core competency evaluation indicator system for pediatric surgery operating room specialist nurses constructed in this study provides a scientific and practical guidance for training pediatric surgery operating room specialist nurses in China.

Objective:To evaluate the efficacy of role-playing games with parental involvement and immediate therapist feedback for children with autism spectrum disorder(ASD)and to explore their impact on parental compe-tence,thereby providing new insights for ASD rehabilitation.Method:Seventy children with ASD were randomly assigned to either a control or an intervention group.The control group received traditional one-on-one role-playing therapy with parents as observers.In addition to this therapy,the intervention group participated in a 60-minute parent-inclusive role-playing session with real-time therapist feedback.Assessments of children's social perspective-taking abilities and parental competence were conducted at pre-and post-intervention and at follow-up.Children's developmental outcomes were further evalu-ated using the Griffiths Scales at the same timepoints.Result:Sixty-four participants provided valid data.The intervention group showed significant improvements in social perspective-taking post-intervention and at follow-up compared to baseline(P<0.05).At follow-up,chil-dren in the intervention group also scored higher on personal and social,hearing,and language development domains of the Griffiths Scale than the control group(P<0.05).Parental competence in the intervention group significantly increased(P<0.05).Conclusion:The integrated intervention of role-playing games with immediate feedback effectively enhances so-cial perspective-taking in children with ASD,promotes developmental levels,and strengthens parental competence.

Objective To observe the repair effect and mechanism of Danhuang Powder-containing serum on high glucose-induced vascular endothelial cell injury.Methods Danhuang Powder-containing serum was prepared.Human umbilical vein endothelial cells(HUVECs)were cultured to be divided into control group,recombinant human epidermal growth factor(called"growth factor"for short)group,Danhuang Powder group,high glucose group,high glucose+growth factor group,and high glucose+Danhuang Powder group.After corresponding intervention in each group for 48 hours,the cell ultrastructure and autophagy were observed under transmission electron microscope,apoptosis was detected by flow cytometry,and the protein expression levels of vascular endothelial growth factor(VEGF),epidermal growth factor(EGF)and basic fibroblast growth factor(bFGF)in the cells were detected by Western Blot.Results(1)The intra-mitochondrial ridges in the control group were clearly visible,autophagosomes and autolysosomes were fewer;mitochondria in the high glucose group were swollen and irregular,and appeared vacuolated;and the more typical autophagy-like structures were seen in the high glucose+Danhuang Powder group.(2)Compared with the high glucose group and high glucose+growth factor group,the apoptosis rate of cells in the high glucose+Danhuang Powder group was significantly decreased(P<0.05).(3)Compared with the high glucose group and the high glucose+growth factor group,the protein expression levels of VEGF,EGF and bFGF in the cells of the high glucose+Danhuang Powder group were significantly increased(P<0.05).Conclusion Danhuang Powder-containing serum can reduce the high glucose-induced damage in HUVEC cells,and its mechanism may be related to the activation of mitochondrial autophagy,and the inhibition of apoptosis,as well as the up-regulation of the expression of VEGF,EGF and bFGF.

Objective To investigate the application of cardiovascular magnetic resonance feature tracking(CMR-FT)in assessing myocardial strain in dilated cardiomyopathy(DCM)patients residing at high altitudes.Methods We retrospectively enrolled 29 DCM patients living at high altitudes(DCM-H),27 DCM patients living in a low-altitude plain environment(DCM-P),23 healthy volunteers living at a high altitude(HV-H),and 24 healthy volunteers living in a low-altitude plain environment(HV-P).All subjects underwent cine MRI scanning using a 3.0T rapid steady-state free precession sequence.The CMR images thus acquired were analyzed using cvi42,a post-processing software,to obtain left ventricular function and myocardial strain parameters.Results Compared with the HV-H group,the DCM-H group showed higher left ventricle end-diastolic volume(LVEDV)and left ventricle end-systolic volume(LVESV),and lower left ventricular ejection fraction(LVEF)and stroke volume(LVSV)(all P＜0.01).No significant difference was observed in cardiac function between the DCM-H and DCM-P groups(all P＞0.05).The absolute values of global radial strain(GRS),global circumferential strain(GCS),and global longitudinal strain(GLS)in the DCM-H group were lower than those in the HV-P group([14.5±6.5]％vs.[34.2±10.7]％,[-11.1±4.4]％vs.[-19.9±2.8]％,and[-7.7±3.2]％vs.[-13.6±4.1]％,respectively),with the differences being statistically significant(all P＜0.001).The DCM-H group had higher absolute GRS,GCS,and GCS values than the DCM-P group did([14.5±6.5]％vs.[7.0±2.7]％,[-11.1±4.4]％vs.[—5.4±2.2]％,and[—7.7±3.2]％vs.[—4.3±1.7]％,respectivley,all P＜0.01).Conclusion Myocardial strain in DCM patients living at a high altitude is lower than that in healthy volunteers living at a high altitude,but higher than that in DCM patients living in a low-altitude plain environment.CMR-FT can be used to quantitatively assess myocardial contractility in DCM patients living at a high altitude,showing promise for clinical application.

Objective To explore the value of combined detection of serum mitogen-activated protein kinase 1(MAPK1)and lysyl oxidase-like protein 2(LOXL2)in early diagnosis of cervical cancer.Methods A total of 218 patients with cervical lesions were selected as study group(103 ca-ses in cervical cancer group,115 cases in benign tumor group).Additionally,100 patients with cer-vical intraepithelial neoplasia grade Ⅱ were selected as precancerous lesion group,and 79 healthy in-dividuals undergoing physical examinations during the same period were selected as control group.Se-rum levels of MAPK1 and LOXL2 were measured in each group.Pearson correlation analysis was used to evaluate the correlations of serum MAPK1 and LOXL2 levels in patients with cervical cancer.Logistic regression analysis was performed to screen influencing factors for the occurrence of cervical cancer.Receiver operating characteristic(ROC)curves were plotted to assess the diagnostic efficacy of serum MAPK1 and LOXL2 for cervical cancer.Results Serum MAPK1 and LOXL2 levels in the study group were higher than those in the precancerous lesion group and the control group,and those in the precancerous lesion group were higher than those in the control group,with statistically signif-icant differences(P＜0.05).The proportion of patients with high-risk human papillomavirus(HPV)infection and serum MAPK1 and LOXL2 levels in the cervical cancer group were higher than those in the benign tumor group,with statistically significant differences(P＜0.05).Serum MAPK1 and LOXL2 levels in patients with stage Ⅲ to Ⅳ cervical cancer were higher than those in patients with stage Ⅰ to Ⅱ cervical cancer,with statistically significant differences(P＜0.05).Pearson correlation analysis showed a positive correlation between serum MAPK1 and LOXL2 levels in patients with cervical cancer(r=0.468,P＜0.001).Logistic regression analysis showed that high-risk HPV infection,MAPK1 and LOXL2 were all influencing factors for the occurrence of cervi-cal cancer(P＜0.05).ROC curve analysis showed that the area under the curve(AUC)for com-bined diagnosis of serum MAPK1 and LOXL2 was 0.911,which was significantly greater than the AUCs for individual diagnoses(0.848 and 0.843,respectively).Conclusion Serum MAPK1 and LOXL2 levels in patients with cervical cancer are significantly upregulated,and the two indicators were positively correlated.High-risk HPV infection,serum MAPK1 and LOXL2 levels were influen-cing factors for the occurrence of cervical cancer.Combined detection of MAPK1 and LOXL2 levels is expected to assist in the diagnosis of cervical cancer.

OBJECTIVE T o carry out the health economics evaluation and cost-benefit analysis of the type b Hae-mophilus influenzae(Hib)vaccination for the children who were hospitalized due to Hib infection so as to provide evidence for public health policies.METHODS The children who were diagnosed with Hib-related respiratory tract infections or meningitis and were hospitalized in respiratory medicine department,infection management depart-ment,emergency rooms and neurology department of Jiangxi Provincial Children's Hospital from Jan.1,2021 to Dec.31,2023 were recruited as the research subjects.Based on a 1∶1 matching condition,the matching variables included four items such as the same age for the admission to the hospital,same gender,same department and same grade of disease severity.The children for whom the primary immunization of Hib vaccination(including Hib monovalent vaccine and Hib-containing combination vaccine)were completed and the integrity of vaccination infor-mation could be checked out were assigned as the intervention group,while the children for whom the primary im-munization of Hib vaccination was not completed were chosen as the control group.The clinical data,vaccination data and the data such as length of hospital stay and hospitalization cost were collected from the children.The cost-benefit of the Hib vaccination among the children with Hib infection was observed.RESULTS A total of 622 hospi-talized children who were detected with Hib-positive respiratory tract infections or meningitis were enrolled in the study,and 73 children(20 children from infection management department,27 children from respiratory medi-cine department,26 children from emergency rooms)were finally included in the intervention group after matc-hing and multiple rounds of screening,73 children were chosen as the control group based on a 1∶1 matching con-dition.The male children accounted for 57.53％(42 cases)in both groups,and the female children accounted for 42.47％(31 cases)in both groups.With the respect to the length of hospital stay,it was 7.00(5.00,8.00)days in the intervention group,7.00(6.00,8.00)days in the control group(Z=-0.341,P=0.733).In terms of the hospitalization cost,it was 7 756.17(6 617.92,10 617.69)yuan in the intervention group,9 040.65(8 033.76,10 935.84)yuan in the control group(Z=-2.795,P=0.005).The cost of Hib vaccination was 343.03 yuan per capita in the intervention group,and the benefit-cost ratio(BCR)was 1∶3.74(343.03 yuan/1 284.48 yuan).CONCLUSIONS The Hib vaccination can save the hospitalization cost and has high cost effectiveness.It is sugges-ted that the Hib vaccination should be promoted and the coverage rate of Hib vaccination should be raised among the age-eligible children.
