ABSTRACT
ObjectiveTo effectively organize the interdisciplinary knowledge of traditional Chinese medicine （TCM） and evidence-based medicine contained in the clinical trial literature of TCM and facilitate the processing and mapping of multi-source data， this paper organized the knowledge of clinical trial literature of TCM by ontology modeling. MethodThe seven-step method and skeleton method were used to develop the ontology. After the structure and language characteristics of TCM clinical trial literature were analyzed， the ontological and non-ontological resources such as top-level framework of Scientific Evidence and Provenance Information Ontology （SEPIO） and TCM language system （TCMLS） were reused to determine the domain concepts and attribute relationship. Finally， the core concepts and attribute relationship such as disease， syndrome， symptom， grouping， intervention measures， outcome indicators and literature quality information were determined. ResultThe information contained in the clinical trial literature of TCM was divided into five categories. According to the Cochrane risk of bias assessment tool and CONSORT 2010 statement， the literature quality evaluation information was mapped to the ontology， and a total of 68 categories， 8 object attributes， and 38 data attributes were established， which basically realized the structured expression of clinical trial literature. ConclusionThe ontology of TCM clinical trial literature constructed in this study can well organize， utilize， and present the construction and association of internal knowledge system in TCM clinical trial literature， underpinning the reasoning of strength of evidence and information of diagnosis and treatment in the future.
ABSTRACT
Objective:To investigate the transcriptomic mechanisms and clinical efficacy of D-CAG regimen for the treatment of acute myeloid leukemia (AML) after failure to initial induction of remission.Methods:The transcriptome data of AML cells before and after the use of dexitabine before August 28, 2021 was searched in Gene Expression Omnibus (GEO) database with "decitabine" as the search term. The R language package was used for differential expression analysis and Kyoto encyclopedia of genes and genomes (KEGG) and gene ontology (GO) enrichment analysis of the data. Protein-protein interaction network (PPI) analysis was conducted on the STRING online analysis website. The accurate treatment prediction platform designed based on logistic omics theory (EpiMed) was used to make drug-disease-target correlation analysis. The clinical data of 18 AML patients treated with D-CAG regimen after failure to induction of remission with standard anthracycline and cytarabine regimen ("3+7" regimen) in the 305th Hospital of Chinese PLA from October 8, 2015 to July 9, 2018 were searched and analyzed, and the curative effect was evaluated. The effects of the dose and duration of each drug on the efficacy were analyzed.Results:The transcriptome data of AML cells before and after the use of decitabine in GSE40442 dataset of the GPL5188 platform were finally selected, updated on July 10, 2014. A total of 366 differentially expressed genes were screened, including 201 up-regulated genes and 165 down-regulated genes. The differential genes were mainly related to cell cycle regulation, bone marrow leukocyte migration and differentiation, transcriptional regulation, bone marrow hematopoiesis and other signaling pathways. Ten core genes such as ANXA5, IL-10, THBS1, TLR4, JUN and CXCL12 were screened by PPI analysis. Drug-disease-target analysis showed that dexitabine had a potential therapeutic effect on various blood diseases such as diffuse large B-cell lymphoma, thrombocytopenia, T-cell acute lymphocytic leukemia, aplastic anemia, and AML. Of the 18 patients, after initial induction of remission, 7 (38.8%) patients achieved partial remission (PR), and 11 (61.2%) patients had no response (NR); after one cycle of re-induction remission therapy, 9 patients had complete remission (CR), 5 patients had PR, 4 patients had NR, and the overall response rate (ORR) was 77.8% (14/18). Compared with patients with NR, the CR rate was higher in patients with PR after initial induction therapy, which were 85.7% (6/7) and 27.3% (3/11), and the difference was statistically significant ( χ2=5.84, P = 0.025). The median duration of cytarabine in CR patients was longer than that in NR patients [10 d (7-14 d) vs. 5 d (2-8 d), Z = 3.89, P = 0.002] and the median ratio of the number of bone marrow blast cells to the duration cytarabine was lower in CR patients than that in NR patients [2.29 (0.89-9.10) vs. 8.10 (3.00-38.50), Z = -2.19, P = 0.006]; the median dose of cytarabine in CR patients was lower than NR patients, which were 50 mg·m -2·d -1 (30-150 mg·m -2·d -1) and 100 mg·m -2·d -1 (50-500 mg·m -2·d -1), and the difference was not statistically significant ( Z = -1.80, P = 0.074). Conclusions:AML patients with PR after initial induction and failure to initial induction of remission may be more likely to achieve CR after the treatment of D-CAG regimen, and this change may be related to the epigenetic regulation of decitabine.
