Aplicación de la dinámica de sistemas en el análisis de la evolución de la hipoacusia y la evaluación del impacto de estrategias sanitarias

Objetivos: Aplicar la dinámica de sistemas para estimar la evolución de la incidencia y la prevalencia de hipoacusia en personas mayores en países de bajos, medios y altos ingresos, así como el acceso al tratamiento, y evaluar la influencia de la implementación de estrategias sanitarias sobre estos indicadores. Metodología: Los análisis se realizaron mediante simulación con dinámica de sistemas según parámetros globales. Para ello, se desarrolló un diagrama de bucles causal, integrando la incidencia, la prevalencia y el tratamiento de hipoacusia con el nivel de desigualdad, factores de riesgo, uso de dispositivos de ayuda auditiva, fuerza laboral de audiólogos y otorrinolaringólogos según el nivel de ingresos del país. Luego, se construyó un diagrama de flujo para ejecutar las simulaciones durante un período de 100 años. Además, se ejecutaron cuatro simulaciones con estrategias sanitarias (reducción de factores de riesgo, mejora en el uso dispositivos de ayuda auditiva, aumento del número de audiólogos y otorrinolaringólogos) y se estimó el porcentaje de cambio respecto al modelo basal. Resultados: Los países de bajos ingresos mostraron una mayor incidencia y prevalencia de hipoacusia, menor acceso a tratamiento adecuado y una mayor prevalencia de hipoacusia sin tratar o con tratamiento inadecuado. La reducción de factores de riesgo creció en un 15 y 33 % la población con audición normal en los próximos 50 y 100 años, respectivamente. Además, la mejora en el uso de dispositivos de ayuda auditiva logró una reducción del 60 % de la población con tratamientos inadecuados o sin tratamiento, y el aumento de audiólogos y otorrinolaringólogos incrementó un 250 % el acceso a un tratamiento adecuado. Conclusiones: La evolución de la salud auditiva está condicionada por factores económicos, donde los entornos más desfavorecidos muestran peores indicadores. Además, la implementación de estrategias combinadas favorecería la salud auditiva en el futuro.

Objectives: To estimate the evolution of the incidence and prevalence of hearing loss in the elderly in low-, middle- and high-income countries by means of system dynamics simulation according to global parameters and to analyze the influence of the implementation of health strategies. Methodology: A causal loop diagram was developed to relate the incidence, prevalence and treatment of hearing loss to the level of inequality, risk factors (RF), use of hearing aids (HA), audiologist and otolaryngologist (ENT) workforce by country income level. A flow chart was then constructed to run the simulations over a 100-year period. In addition, four simulations were run with health strategies (reduction of RF, improvement in HA use, increase in the number of audiologists and ENT specialists) and the percentage change from the baseline model was estimated. Results: Low-income countries showed a higher incidence and prevalence of hearing loss, less access to adequate treatment, and a higher prevalence of untreated or inadequately treated hearing loss. The reduction of RF increased the population with normal hearing by 15% and 33% over the next 50 and 100 years, respectively. In addition, the improvement in the use of ha achieved a 60% reduction in the population with inadequate or untreated treatment, and the increase in audiologists and ENT specialists improved the access to adequate treatment by 250%. Conclusions: The evolution of hearing health is conditioned by economic factors, where the most disadvantaged environments show worse indicators. In addition, the implementation of combined strategies would favor hearing health in the future. System dynamics is a very useful methodology for health managers because it enables to understand how a disease evolves and define what are the best health interventions considering different scenarios.

Objetivos: Aplicar a dinâmica do sistema para estimar a evolução da incidência e prevalência da perda auditiva em pessoas idosas em países de baixo, médio e alto rendimento, bem como o acesso ao tratamento, e avaliar a influência da implementação de estratégias de saúde sobre estes indicadores. Metodologia: As análises foram conduzidas utilizando simulação da dinâmica do sistema com base em parâmetros globais. Para tal, foi desenvolvido um diagrama do laço causal, integrando a incidência, prevalência e tratamento da perda auditiva com o nível de desigualdade, fatores de risco, utilização de aparelhos auditivos, mão-de-obra de audiologistas e otorrinolaringologistas por nível de rendimento nacional. Foi então construído um fluxograma para executar as simulações ao longo de um período de 100 anos. Além disso, foram realizadas quatro simulações com estratégias de saúde (reduzindo os fatores de risco, melhorando a utilização de aparelhos auditivos, aumentando o número de audiologistas e otorrinolaringologistas) e foi estimada a mudança percentual em relação ao modelo de base. Resultados: Os países de baixos rendimentos mostraram maior incidência e prevalência de perda auditiva, menor acesso a tratamento apropriado e maior prevalência de perda auditiva não tratada ou tratada de forma inadequada. A redução dos fatores de risco aumentou a população com audição normal em 15 e 33% durante os próximos 50 e 100 anos, respectivamente. Além disso, uma melhor utilização de aparelhos auditivos permitiu uma redução de 60% na população mal tratada ou não tratada, e o aumento do número de audiologistas e especialistas em ORL aumentou em 250% o acesso ao tratamento adequado. Conclusões: A evolução da saúde auditiva é condicionada por fatores económicos, com os ambientes mais desfavorecidos a apresentarem indicadores piores. Além disso, a implementação de estratégias combinadas favoreceria a saúde auditiva no futuro.

Credibility, accuracy and readability of patient-oriented information about low back pain on Brazilian websites: a mixed-method review / Credibilidade, acurácia e legibilidade das informações orientadas ao paciente sobre dor lombar em sites brasileiros: uma revisão de método misto

ABSTRACT BACKGROUND AND OBJECTIVES: Low-quality online health-related content may lead to inefective or harmful decision-making from patients related to their healthcare. The aim of this study was to evaluate the credibility, accuracy and readability of web-based content on Brazilian websites. METHODS: This is a mixed-method review with exploratory sequential design. Google was selected as the search engine for retrieving web-information about low back pain (LBP) in Brazilian websites. We assessed the URL on three domains: credibility, accuracy, and readability. Qualitative analysis of each URL was performed in three steps: (1) organization into thematic units; (2) data exploration; and (3) interpretation of the data and summarization. RESULTS: Credibility was assessed in 135 URLs, 72 (53%) URLs had no authorship, 119 (88%) did not mention the sources of their information, none presented a declaration of conflict of interest or the declared source of funding, 76 (56%) URLs present the date of creation. Accuracy was assessed in 121 URLs and none fully adhered to the guidelines. Readability was assessed in 128 and texts were classified as "very easy" or "easy" to read. Five main themes emerged in the qualitative analysis: (1) Explanations and causes for low back pain, (2) diagnosis, (3) recommendation about treatment, (4) recommendation for coping and self-management, and (5) lifestyle factors. CONCLUSION: Content analysis of web-based searches on the Brazilian Portuguese language demonstrated low credibility standards, mostly inaccurate information, and moderate-high readability levels about low back pain.

RESUMO JUSTIFICATIVA E OBJETIVOS: O conteúdo on-line relacionado à saúde quando apresenta baixa qualidade pode levar a tomadas de decisão ineficazes ou prejudiciais por parte dos pacientes.

O Google foi selecionado como o mecanismo de busca para recuperar informações da web sobre dor lombar em sites brasileiros. Avaliamos os URL em três domínios: credibilidade, acurácia e legibilidade. A análise qualitativa de cada URL foi realizada em três etapas: (1) organização em unidades temáticas; (2) exploração de dados; e (3) interpretação dos dados e resumo. RESULTADOS: A credibilidade foi avaliada em 135 URLs, 72 (53%) URLs não tinham autoria, 119 (88%) não mencionavam as fontes de suas informações, nenhuma apresentava declaração de confito de interesse ou fonte de fnanciamento declarada, 76 (56%) URLs apresentam a data de criação. A acurácia foi avaliada em 121 URLs e nenhuma aderiu totalmente às diretrizes. A legibilidade foi avaliada em 128 e os textos foram classificados como "muito fáceis" ou "fáceis" de ler. Cinco temas principais emergiram na análise qualitativa: (1) Explicações e causas da dor lombar, (2) diagnóstico, (3) recomendação sobre tratamento, (4) recomendação para enfrentamento e autogerenciamento e (5) fatores de estilo de vida. CONCLUSÃO: A análise de conteúdo de pesquisas baseadas na web, no idioma português do Brasil, demonstrou baixos padrões de credibilidade, acurácia e níveis moderados a altos de legibilidade sobre a dor lombar.

Screening and functional verification of key genes in acute myeloid leukemia / 白血病·淋巴瘤

Objective:To explore the key genes related to the development, progression and prognosis of acute myeloid leukemia (AML) based on bioinformatics, and to analyze their functions.Methods:The chip expression profile GSE84881 data set of AML patients including 19 AML samples and 4 normal tissue samples was downloaded from the gene expression omnibus (GEO) database. GEO online tool GEO2R was used to screen the differentially expressed genes (DEG). The DAVID online database was used to make gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) enrichment analysis of DEG. The STRING online database was used to analyze the protein interaction (PPI) network of DEG, and the key genes were screened by using the Cytoscape software. The weighted gene co-expression network analysis (WGCNA) was used to build co-expressed network and obtain the central genes.LC-Bio online platform was used to construct Venn diagram and the key genes and central genes in PPI were crossed to finally obtain the true key genes. RNA-seq datasets GSE2191 and GSE90062 of human tissues were downloaded from GEO database to verify the screened key genes. Kaplan-Meier method was used to analyze the effects of key genes on the overall survival (OS) of AML based on the data of GEPIA database.Results:A total of 247 DEG were identified in GSE84881 data set, including 112 up-regulated genes and 135 down-regulated genes. According to the results of GO enrichment analysis, 247 DEG were mainly enriched in the regulation of signal transduction and cell proliferation in the biological process (BP); the cell composition (CC) revealed that these genes were mainly involved in the cytoplasm and exosomes; the molecular function (MF) analysis showed that these genes were mainly enriched in protein binding and calcium binding. Further KEGG pathway enrichment analysis showed that these 247 DEG were mainly involved in NOD-like receptor signal pathway and interleukin 17 (IL-17) signal pathway. And then the 12 key genes were obtained from PPI. WGCNA software was used to screen 13 central genes from GSE84881 dataset and finally 1 real key gene EGF was obtained after taking intersection. Kaplan-Meier method showed that OS time of AML patients in EGF high expression group was decreased than that in EGF low expression group, and the difference was statistically significant( P = 0.044). Conclusions:EGF may be an important diagnosis and treatment target of AML and may become a potential biomarker for clinical treatment and prognosis prediction of AML.

Objective:To study the practical efficacy of the clinical decision support system for diagnosis and treatment of thyroid cancer (CDSS-TC) in assisting doctors to complete several diagnosis and treatment tasks, and to make a preliminary evaluation of its clinical practicability according to the test results.Methods:From Jan. 2022 to Mar. 2022, 90 patients with thyroid cancer who were admitted to the Head and Neck Surgery Department of Shaw Hospital affiliated to Zhejiang University were prospectively analyzed, and the average time spent in reading the pre-operative B-ultrasound report, as well as the individual fitness of the dose adjustment of eugenol in 70 patients with thyroid cancer after surgery. A retrospective analysis was made of the compliance of the basis of the "recommended scheme" and the deviation of the basis of the doctor’s "final scheme" for the preoperative surgery of 120 patients with thyroid cancer who were treated for the first time in the head and neck surgery of Shaw Hospital affiliated to Zhejiang University from Mar. 2021 to May. 2021. All cases were treated by pure artificial (group A) and CDSS-TC assisted (group B) , and the differences in organization were compared.Results:The average time for disposal of a single B-ultrasound report in Group B was much shorter than that in Group A ( P=5.600E-04) ; The number of patients with excellent grade and the total number of patients with excellent grade and qualified grade recommended by the doctor in group B were significantly higher than those in group A ( P=7.819E-20 and P=1.335E-18) ; The conformity rate of the basis of CDSS-TC "Recommended Scheme" ≥ 98%; The deviation rate of the basis for "final protocol" of doctors in group B was lower than that in group A ( P=0.059 for total resection or not, P=0.075 for lateral neck dissection or not) . Conclusions:CDSS-TC can accurately extract the disease-related source information in all the original examination/laboratory reports, and provide accurate decision-making suggestions through efficient correlation analysis. In view of the accurate and objective conclusions of its analysis, it can provide high-quality and all-link decision support for doctors’ clinical diagnosis and treatment, and is an ideal information work platform.

Effects of long non-coding RNA HAGLR on the prognosis of breast cancer and the construction of competitive endogenous RNA interaction network / 肿瘤研究与临床

Objective:To explore the expression of long non-coding RNA (lncRNA) HAGLR in breast cancer and its effect on the prognosis of breast cancer, and to construct a competitive endogenous RNA (ceRNA) network.Methods:The Atlas of Genetics and Cytogenetics in Oncology and Haematology website was used to search for HAGLR chromosome gene mapping and transcript expression. The lnclocater website was used to predict the subcellular localization of HAGLR, and the differential expression of HAGLR in breast cancer tissues and adjacent tissues was analyzed by using lnCAR database. The patients in lnCAR database were divided into HAGLR high expression group and HAGLR low expression according to HAGLR expression. The Kaplan-Meier method was used to analyze the overall survival (OS) and metastasis-free survival, which was verified by using UCSC Xena database. lnCAR database was used to search the co-expressed genes of HAGLR. The top 200 co-expressed genes were submitted to the Metascape website for Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) functional enrichment analysis, and protein interaction network (PPI) was constructed. Starbase, a bioinformatics online analysis website, was used to predict HAGLR targeting mircoRNA (miRNA) and mRNA that directly encoded proteins. ceRNA network of HAGLR was constructed with Cytoscape3.8 software.Results:HAGLR gene was localized in 2q31.1 and mainly distributed in cytoplasm. The expression level of HAGLR in breast cancer tissues was higher than that in adjacent tissues, and the difference was statistically significant ( P < 0.001). lnCAR database and UCSC Xena database analysis showed that OS in HAGLR high expression group was worse than that in HAGLR low expression group (all P < 0.01). lnCAR database, the metastasis-free survival in HAGLR high expression group was worse than that in HAGLR low expression group ( P = 0.030). Among the top 200 HAGLR co-expressed genes, 129 genes were negatively correlated with HAGLR and 71 genes were positively correlated with HAGLR. KEGG pathway analysis showed that HAGLR was related to metabolic pathways, MAPK signaling pathway, JAK-STAT signaling pathway and cancer pathway. GO annotation analysis showed that HAGLR was mainly enriched in cell cycle, centromeric complex assembly, mitotic progression, protein kinase binding, kinase activity regulation, cell response to DNA damage stimulation and other functions. hsa-miR-130b-3p, hsa-miR-1245b-5p, hsa-miR-182b-5p, hsa-miR-512-3p, hsa-miR-302b-3p, hsa-miR-185b-5p, hsa-miR-106b-5p were HAGLR targeting miRNA. Conclusions:HAGLR is highly expressed in breast cancer tissues, and it may be a biomarker for predicting the prognosis of breast cancer.

Screening of endoplasmic reticulum stress signature-related genes in gastric cancer and the establishment of prognostic risk models / 肿瘤研究与临床

Objective:To screen the endoplasmic reticulum stress (ERS) signature-related differentially expressed genes (DEG) in gastric cancer and to construct a prognostic risk model based on a bioinformatics.Methods:Transcriptome sequencing data (RNA-seq) of 375 gastric cancer and 32 paracancerous tissue samples downloaded from The Cancer Genome Atlas (TCGA) database and the corresponding clinical information were obtained as training set samples; data of 387 gastric cancer patients (GSE84437) from Gene Expression Omnibus (GEO) database were downloaded as validation set samples. All data were obtained on December 25, 2021. A total of 785 ERS signature-related genes (ERS-RG) were obtained from the GeneCards database. DEG between gastric cancer tissues and paracancerous tissues in the TCGA database was analyzed. The identified gastric cancer DEG were intersected with ERS-RG from the GeneCards database to obtain gastric cancer ERS signature-related DEG, which were analyzed for gene ontology (GO) function and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment. Univariate Cox proportional risk model was used to screen ERS signature-related DEG with prognostic value in gastric cancer, and LASSO regression analysis was performed to construct a polygenic prognostic risk model, and to calculate the prognostic risk score. The patients in training set and validation set were divided into high-risk group and low-risk group according to the median of the prognostic risk score (2.369); Kaplan-Meier survival analysis was used to compare the overall survival (OS) and to draw time-dependent receiver operating characteristic (ROC) curves of patients in the two groups; nomogram was drawn based on the prognostic independent influencing factors of gastric cancer. The characteristic immune cell infiltration abundance between the two groups was analyzed by using the inverse convolution-based CIBERSORT algorithm. Cytolytic activity scores were calculated by using the geometric mean of granzyme A and perforin 1 expression. According to the median prognostic risk score (2.369) and median tumor mutation burden (TMB) (3.000), all patients with gastric cancer were divided into high risk score-high TMB group, high risk score-low TMB group, low risk score-high TMB group and low risk score-low TMB group to compare the OS of patients in each group.Results:A total of 444 ERS signature-related DEG in gastric cancer including 168 down-regulated genes and 276 up-regulated genes were obtained, which were mainly enriched in biological processes such as protein processing in the endoplasmic reticulum, extracellular matrix (ECM) receptor interactions and unfolded protein responses (all P < 0.05). Univariate Cox regression analysis showed that 12 prognostic-related ERS signature-related DEG in gastric cancer were screened out. LASSO regression analysis was performed to obtain a prognostic risk score = 0.052×NOS3+0.137×PON1+0.067×CXCR4+0.131×MATN3+0.116×ANXA5+0.090×SERPINE1. The results of Kaplan-Meier analysis showed that the OS of the low-risk group in both the training and validation sets was better than that of the high-risk group (all P < 0.01). The results of the time-dependent ROC curve analysis showed that the AUC for the 3-year, 5-year, 8-year OS rates was 0.695, 0.786, 0.698, respectively in the training set, while the AUC for the 3-year 5-year, 8-year OS rates was 0.580, 0.625, 0.627, respectively in the validation set. Multivariate Cox regression analysis showed that prognostic risk score ( HR = 3.598, 95% CI 2.290-5.655, P < 0.001) and tumor stage ( HR = 1.344, 95% CI 1.057-1.709, P < 0.05) were independent factors influencing the prognosis of gastric cancer. Among 375 gastric cancer patients in the TCGA database, the expression levels of ATF6, HSPA5, XBP1 and ATF4 in the high-risk group were higher than those in the low-risk group (all P < 0.05); CIBERSORT results showed that the abundance of activated CD4 memory T cells in the high-risk group was lower than that in the low-risk group, and the abundance of both M0 and M2 macrophages in the high-risk group was higher than that in the low-risk group (all P < 0.05). The expression levels of common immune checkpoints (CD274, CTLA4, TNFRSF9, TIGIT, PDCD1, LAG3) in the high-risk group were all higher than those in the low-risk group (all P < 0.05). Cytolytic activity score in the high-risk group was higher than that in the low-risk group ( P < 0.05). The prognostic risk score was negatively correlated with TMB ( r = -0.20, P < 0.001). Patients in the low-risk score-high TMB group had the best OS and those in the high-risk score-low TMB group had the worst OS (both P < 0.001). Conclusions:The prognostic risk score model is established based on 6 ERS signature-related DEG in gastric cancer and its prognostic risk score may be effective as an independent prognostic factor to predict the prognosis of gastric cancer patients.

Construction and validation of a prognostic model for colon cancer based on inflammatory response-related genes / 肿瘤研究与临床

Objective:To screen the differentially expressed genes (DEG) related to inflammatory response associated with the prognosis of colon cancer based on the bioinformatics approach, and to construct and validate a prognostic model for colon cancer.Methods:RNA sequencing and clinical data of 472 colon cancer patients and normal colon tissues of 41 healthy people were retrieved from the Cancer Genome Atlas (TCGA) database. Gene expression related to prognosis of colon cancer and clinical data were retrieved from the International Cancer Genome Consortium (ICGC) database. The retrieval time was all from the establishment of library to November 2022. A total of 200 genes associated with inflammatory response obtained from the Gene Set Enrichment Analysis (GSEA) database were compared with the RNA sequencing gene dataset of colon cancer and normal colon tissues obtained from the TCGA database, and then DEG associated with inflammatory response were obtained. The prognosis-related DEG in the TCGA database were analyzed by using Cox proportional risk model, and the inflammatory response-related DEG were intersected with the prognosis-related DEG to obtain the prognosis-related inflammatory response-related DEG. The prognostic model of colon cancer was constructed by using LASSO Cox regression. Risk scores were calculated, and colon cancer patients in the TCGA database were divided into two groups of low risk (< the median value) and high risk (≥the median value) according to the median value of risk scores. Principal component analysis (PCA) was performed on patients in both groups, and survival analysis was performed by using Kaplan-Meier method. The efficacy of risk score in predicting the overall survival (OS) of colon cancer patients in the TCGA database was analyzed based on the R software timeROC program package. Clinical data from the ICGC database were applied to externally validate the constructed prognostic model, and patients with colon cancer in the ICGC database were classified into high and low risk groups based on the median risk score of patients with colon cancer in the TCGA database. By using R software, single-sample gene set enrichment analysis (ssGESA), immunophenotyping difference analysis, immune microenvironment correlation analysis, and immune checkpoint gene difference analysis of immune cells and immune function were performed for prognosis-related inflammation response-related DEG in the TCGA database.Results:A total of 60 inflammatory response-related DEG and 12 prognosis-related DEG were obtained; and 6 prognosis-related inflammatory response-related DEG (CCL24, GP1BA, SLC4A4, SRI, SPHK1, TIMP1) were obtained by taking the intersection set. LASSO Cox regression analysis showed that a prognostic model for colon cancer was constructed based on 6 prognosis-related inflammatory response-related DEG, and the risk score was calculated as = -0.113×CCL24+0.568×GP1BA+ (-0.375)×SLC4A4+(-0.051)×SRI+0.287×SPHK1+0.345×TIMP1. PCA results showed that patients with colon cancer could be better classified into 2 clusters. The OS in the high-risk group was worse than that in the low-risk group in the TCGA database ( P < 0.001); the area of the curve (AUC) of the prognostic risk score for predicting the OS rates of 1-year, 3-year, 5-year was 0.701, 0.685, and 0.675, respectively. The OS of the low-risk group was better than that of the high-risk group in the ICGC database; AUC of the prognostic risk score for predicting the OS rates of 1-year, 2-year, 3-year was 0.760, 0.788, and 0.743, respectively. ssGSEA analysis showed that the level of immune cell infiltration in the high-risk group in the TCGA database was high, especially the scores of activated dendritic cells, macrophages, neutrophils, plasmacytoid dendritic cells, T helper cells, and follicular helper T cells in the high-risk group were higher than those in the low-risk group, while the score of helper T cells 2 (Th2) in the high-risk group was lower compared with that in the low-risk group (all P < 0.05); in terms of immune function, the high-risk group had higher scores of antigen-presenting cell (APC) co-inhibition, APC co-stimulation, immune checkpoint, human leukocyte antigen (HLA), promotion of inflammation, parainflammation, T-cell stimulation, type Ⅰ interferon (IFN) response, and type ⅡIFN response scores compared with those in the low-risk group (all P < 0.05). The results of immunophenotyping analysis showed that IFN-γ-dominant type (C2) had the highest inflammatory response score, and the differences were statistically significant when compared with trauma healing type (C1) and inflammatory response type (C3), respectively (all P < 0.05). Immune microenvironment stromal cells and immune cells were all positively correlated with prognostic risk scores ( r values were 0.35 and 0.21, respectively, both P < 0.01). The results of immune checkpoint difference analysis showed there was a statistically significant difference in programmed-death receptor ligand 1 (PD-L1) expression level between high-risk group and low-risk group ( P = 0.002), and PD-L1 expression level was positively correlated with prognostic risk score ( r = 0.23, P < 0.01). Conclusions:Inflammatory response-related genes may play an important role in tumor immunity of colon cancer and can be used in the prognostic analysis and immunotherapy of colon cancer patients.

Teaching practice and exploration of the optional course of medical informatics for non-informatics students in medical colleges and universities / 中华医学教育探索杂志

Nowadays, the new healthcare industry is closely integrated with the new-generation information techniques such as mobile Internet, Internet of things, cloud computing, and big data, which proposes higher requirements for the teaching objectives and contents of the optional course of medical informatics for non-informatics students in medical colleges and universities. Based on the actual teaching demands and the training objectives of clinical medical students, the teaching contents of the optional course of medical informatics were scientifically optimized and allocated. With "small datasets and basic application of electronic medical records/electronic health records" in medical informatics education as the main contents, numeric data, text data, and image data were modularized in medical information processing, and the methods of flipped classroom and case-driven teaching were adopted. The commonly used methods in machine learning (such as regression, classification, and clustering methods) were introduced and applied in task-based case studies, and the comprehensive algorithm case report was used for course assessment and evaluation. The teaching practice has shown that the above exploration not only stimulated the interest in the optional course of medical informatics among students, but also effectively implemented the "five early" mode of early prediction, early adjustment, early identification, early diagnosis, and early treatment among medical students.
