Artificial intelligence-based medical decision-making systems can significantly accelerate decision processes and enhance accuracy.However,challenges persist in achieving personalized care and in the compre-hensive collection of medical data.This paper explores potential solutions to these issues by examining AI ap-plications in diagnostic omics and multi-dimensional data acquisition,providing an overview of current pro-gress and limitations in developing intelligent medical decision systems through these approaches.Additional-ly,the paper also discusses the broad potential for artificial intelligence applications in medical education and their possible contributions to advancing overall decision-making standards in healthcare.

Objective To screen the key N6-methyladenosine(m6A)methylation related genes in renal clear cell carcinoma(ccRCC),and to study their expression and relationship with the prognosis,migration and invasion of renal clear cell carcinoma.Methods The RNA sequencing data and clinical data of ccRCC and ad-jacent tissues were downloaded from the Cancer Genome Atlas(TCGA)and GTEx(Genotype-Tissue Expres-sion).The expression profile and prognosis were analyzed with R 4.1.1,and the key genes were screened.Clinical specimens of 10 patients with ccRCC were collected.The mRNA and protein expressions were detec-ted by RT-qPCR and immunohistochemistry,respectively.In human ccRCC cell line RCC23,siRNA was used to knock down key genes,and CCK-8 was used to detect the survival rate of cells.Scratch test and Trans well test were used to detect the migration and invasion of cells,respectively.Results Among the 19 m6A methyl-ation related genes,only insulin-like growth factor 2 mRNA binding protein 3(IGF2BP3)was highly ex-pressed in cancer tissues,and the high expression was significantly positively correlated with poor prognosis.The high expression of IGF2BP3 was verified in clinical specimens by RT-qPCR and immunohistochemistry.After knockdown of IGF2BP3 by siRNA,the survival rate of RCC23 cells decreased significantly,and the mi-gration and invasion ability of cut cells decreased.Conclusion These results suggest that IGF2BP3 may be an effective biomarker and potential drug target for predicting the prognosis of patients with ccRCC.

Objective To assess the clinical utility of single-molecule real-time technology(SMRT)in identifying triplicated α-globin genes and compound variant alleles.Methods A total of 36 samples with tripli-cated α-globin genes were collected.Among them,28 samples were confirmed by PCR flow-through hybridiza-tion and 8 samples were confirmed by Next Generation Sequencing(NGS).These 36 samples included tripli-cated α-globin genes compound variants with cis or trans arrangements unknown,such as αααanti4 2 compoundαcsα(2 cases),αααanti4.2 compound-α3.7(10 cases),and HKαα/--SEA pending confirmation(2 cases),SMRT technology was employed to detect thalassemia gene variants.Additionally,a pedigree with the genotype ofαααanti4.2 compound-α3.7 variant was recruited,including the proband(Ⅱ-1),its father(Ⅰ-1),and mother(Ⅰ-2).PCR flow-through hybridization and SMRT were employed to detect thalassemia gene variants.Results SMRT detected 35 out of 36 samples with triplicated α-globin genes,and 1 sample with quadrupllcated α-globin genes(ααααanti4.2).Among the 2 αααanti4 2 compound αCSα variant samples,both αααanti42 and αCSα were arranged in trans,with a genotype of αααanti4.2/αCSα.Among the 10 αααanti4.2 compound-α3.7 variant samples,9 samples hadαααanti4.2 and-α3.7 in a cis arrangement,with a genotype of HKαα/αα,and 1 sample had αααannti4.2 and-α3.7 in a trans arrangement,with a genotype of αααanti4.2/-α3.7.Compared with PCR flow-through hybridization,SMRT detected one case of a large segment deletion in the β-globin gene and two unknown variants,which led to an increase in the positive detection rate of approximately 10.71％(3/28).The pedigree analysis showed that the proband(Ⅱ-1)inherited αααanti4.2 and-α3.7 variants from his mother(Ⅰ-2),with a genotype of HKαα/αα,con-sistent with the SMRT detection results.Conclusion SMRT can accurately detect triplicated or quadrupllcat-ed α-globin genes,and compound variant alleles.It offers high accuracy,enables one-step identification of cis or trans arrangements,and provides comprehensive coverage of thalassemia gene variations,demonstrating its significant clinical value.

Objective To explore the relationship between minimal residual disease(MRD)on the 19th day(D19)and prognosis of children with acute B-lymphoblastic leukemia(B-ALL),as well as the correlation with related biological changes.Methods A total of 88 children with B-ALL newly diagnosed in this hospital from April 2016 to April 2020 who met the enrollment conditions were analyzed for induction therapy D19 MRD,overall survival(OS)rate,event-free survival(EFS)rate,chromosome karyotype,fusion gene and mu-tation gene.MRD≥ 0.01％was considered positive,and they were divided into MRD positive group and MRD negative group.The characteristics of OS rate,EFS rate,immunophenotype and molecular biology/cytogenet-ics were compared between the two groups over a period of 3 years.Results The 3-year OS rate and EFS rate of 88 pediatric patients were 92.0％and 86.4％,respectively.The rates of OS rate and EFS rate in MRD posi-tive group were lower than those in MRD negative group,with statistical significance(P＜0.05).The detec-tion rate of CD10 in MRD positive group was lower than that in MRD negative group,and the difference was statistically significant(P＜0.05).Thirty-two patients(36.4％)detected 8 types of 35 fusion genes.The de-tection rates of BCR-ABL1 and E2A-PBX1 in MRD positive group were higher than those in MRD negative group,and the differences were statistically significant(P＜0.05).Among 48 cases(54.5％)of pediatric pa-tients,41 types of 91 mutated genes were detected,and the remaining mutated genes were less than 5 cases.Abnormal karyotype was detected in 18 cases(20.5％),and no mitotic phase was detected in 17 cases.There was no difference in MRD between normal and abnormal karyotype.Binary Logistic regression analysis showed that BCR-ABL1 and E2A-PBX1 were prognostic factors of children with B-ALL.Conclusion The positive D19 MRD is the influential factor of adverse OS and EFS in children with B-ALL.Both E2A-PBX1 and BCR-ABL1 have adverse effects on the prognosis of children with B-ALL.
