The diagnosis of hematological disorders is currently established from the combined results of different tests, including those assessing morphology (M), immunophenotype (I), cytogenetics (C), and molecular biology (M) (collectively known as the MICM classification). In this workflow, most of the results are interpreted manually (i.e., by a human, without automation), which is expertise-dependent, labor-intensive, time-consuming, and with inherent interobserver variability. Also, with advances in instruments and technologies, the data is gaining higher dimensionality and throughput, making additional challenges for manual analysis. Recently, artificial intelligence (AI) has emerged as a promising tool in clinical hematology to ensure timely diagnosis, precise risk stratification, and treatment success. In this review, we summarize the current advances, limitations, and challenges of AI models and raise potential strategies for improving their performance in each sector of the MICM pipeline. Finally, we share perspectives, highlight future directions, and call for extensive interdisciplinary cooperation to perfect AI with wise human-level strategies and promote its integration into the clinical workflow.

High mobility group box 1 (HMGB1), when released extracellularly, plays a pivotal role in the development of spinal cord synapses and exacerbates autoimmune diseases within the central nervous system. In experimental autoimmune encephalomyelitis (EAE), a condition that models multiple sclerosis, the levels of extracellular HMGB1 and interleukin-33 (IL-33) have been found to be inversely correlated. However, the mechanism by which IL-33 deficiency enhances HMGB1 release during EAE remains elusive. Our study elucidates a potential signaling pathway whereby the absence of IL-33 leads to increased binding of P300/CBP-associated factor with HMGB1 in the nuclei of astrocytes, upregulating HMGB1 acetylation and promoting its release from astrocyte nuclei in the spinal cord of EAE mice. Conversely, the addition of IL-33 counteracts the TNF-α-induced increase in HMGB1 and acetylated HMGB1 levels in primary astrocytes. These findings underscore the potential of IL-33-associated signaling pathways as a therapeutic target for EAE treatment.

Objective To understand the latent profiles of kinesiophobia in kidney transplant recipients and explore the influencing factors of different profiles.Methods A cross-sectional study was conducted on 230 kidney transplant recipients subjected with convenient sampling from Department of Nephrology,the First Affiliated Hospital of Army Medical University from November 2024 to February 2025.General Information Questionnaire,Tampa Scale of Kinesiophobia-11(TSK-11),Exercise Compliance Questionnaire,Fatigue Scale-14(FS-14),Patient Health Questionnaire-9(PHQ-9)and Chinese Version of the Self-Efficacy to Manage Chronic Disease Scale(C-SEMCD)were used for investigation and latent profile analysis.Univariate analysis and logistic regression analysis were applied to explore the influencing factors of different profiles.Results Kinesiophobia in the participants was classified into 3 latent profiles:fearless movement type-low kinesiophobia group(54 cases,23.48%),cautious movement type-moderate kinesiophobia group(98 cases,42.61%),and resistant movement type-high kinesiophobia group(78 cases,33.91%).Statistical differences were observed among the 3 groups in terms of age,education level,post-operative duration,depression score,fatigue score,and self-efficacy score of chronic disease management(P<0.05).Logistic regression analysis showed that age(OR=8.82,95%CI:1.27～61.10),education level[junior high school or below(OR=0.14,95%CI:0.04～0.50);technical secondary school or senior high school(OR=0.08,95%CI:0.02～0.27)],post-operative duration[<1 year(OR=11.39,95%CI:2.53～51.30);1-5 years(OR=11.05,95%CI:2.48～49.22)],fatigue(OR=1.32,95%CI:1.10～1.59),and depression(OR=1.53,95%CI:1.19～1.98)were influencing factors for resistant movement type-high kinesiophobia in the kidney transplant recipients.Education level(technical secondary school or senior high school:OR=0.32,95%CI:0.12-0.86)and self-efficacy of chronic disease management(OR=0.95,95%CI:0.90-1.00)were influencing factors for cautious movement type-moderate kinesiophobia in the recipients.Conclusion Kinesiophobia in kidney transplant recipients can be classified into 3 latent profiles.Recipients'age,education level,post-operative duration,fatigue,and depression are influencing factors for the resistant movement type-high kinesiophobia,and education level and chronic disease management self-efficacy are important influencing factors for the cautious movement type-moderate kinesiophobia.

Liver cancer is one of the most common cancers,and its common surgical treatment methods include tran-scatheter arterial chemoembolization,radiofrequency ablation,and liver transplantation surgery.However,the treatment effect of these surgeries on patients with mid-to late-stage liver cancer is not ideal.In recent years,with the continuous development of tumor gene therapy and tumor immunology,tumor treatment methods have transitioned from traditional models to targeted onco-lytic virus therapy.With the advantages of fast replication,the oncolytic virus can kill tumor cells without damaging other normal cells and realize the targeted treatment of liver cancer through mechanisms such as activating the immune system and improving the tumor microenvironment.In addition,immunotherapy can reduce tumor recurrence and metastasis,thereby exerting therapeutic effects on liver cancer.This article reviews the research progress of oncolytic virus and immunotherapy for liver cancer,aiming to provide a reference for the clinical treatment of liver cancer.

Objective To summarize the experience of integrative palliative care at Peking Union Medi-cal College Hospital and provide a reference for promoting the integrative palliative care model.Methods Twenty cases receiving integrative palliative care at Peking Union Medical College Hospital were collected.The clinical characteristics,reasons for initiating integrative palliative care,the process of integrative palliative care,and feedback from these cases were summarized.Results Insomnia(11 cases,55％)and pain(9 cases,45％)were the most common symptoms requiring control in the 20 cases.The integrative palliative care team assisted in medical decision-making for 17 cases(85％),prepared end-of-life for 9 cases(45％),assisted in the transfer for 3 cases(15％),and provided comfort care for all the 20 cases(100％).Conclusions The integrative palliative care model can help alleviate suffering in end-of-life patients and provide support to patients'families and the original medical teams.This model is worth further promotion within class A tertiary hospitals.

Traumatic brain injury (TBI) can cause a series of secondary changes, such as neuronal dysfunction, blood-brain barrier destruction, secondary neurovascular injury, neuroinflammation, and even neurodegenerative diseases. In recent years, studies have found that microglia can regulate the long-term inflammation and tissue repair process after TBI through the changes of M1 phenotype and M2 phenotype, affecting the TBI progress. Therefore, this article reviews the recent advance in role of microglia, regulatory mechanisms and related therapies of microglia after TBI, in order to provide some references for TBI treatment.

Objective:This study aimed to analyze the genomic characteristics of Varicella-Zoster Virus (VZV) strains circulating in Jilin province from 2010 to 2023.Methods:Vesicle fluid from 78 sporadic cases with VZV infection were collected in Jilin province from 2010 to 2023, after detecting by Real-time PCR, 26 specimens (CT<25) were detected by PCR. Open reading frame 22(ORF22), ORF38 and ORF62 were amplified and analyzed. Genotyping was confirmed by SNPs ORF22 (37902, 38019, 38055, 38081 and 38177) and ORF38 (69424). Vaccine strains were indentified from wild-type strains according to ORF38 (69349) and ORF62 (106262, 107252, and 108111). Sequences were analyzed by homologous comparison and phylogenetic analysis.Results:The comparison with Dumas sequence revealed that SNPs (37902, 38055, 38081 and 38177) in ORF22 and ORF38 (69424) have mutations similar to the pOka strain, which belong to clade 2. Compared to the Dumas and Baike strains, all 26 samples were wild-type strains. JL2016-4 strain changes from threonine to asparaginyl at position 38059, JL2021-4 strain changes from arginine to proline at position 37933, from aspartic acid to tyrosine at position 37935, and from aspartic acid at base 38031 to tyrosine. JL2023-1 strain changes from arginine to leucine at position 37933.Conclusions:VZV has been prevalent for 14 years in Jilin province. The main epidemic strains belong to the clade 2. We should strengthen the monitoring of VZV outbreaks and raise the coverage rate of VZV vaccination.

Objective To analyze the distribution characteristics of abnormal karyotypes of fetal sex chromosome aneuploidy(SCA)and pregnancy outcomes in 101 fetal cases.Methods A retrospective study was conducted among 7 821 pregnant women who underwent successfully prenatal karyotyping diagnosis at Guangxi Zhuang Autonomous Region People's Hospital from January 2016 to December 2021.All women received amniotic fluid cell culture karyotype analysis and copy number variation sequencing(CNV-seq)detection and 101 cases of SCA detected were analyzed.Results A total of 101 cases were detected by SCA,with a detection rate of 1.29％.Among them,Klinefelter syndrome accounted for 33.66％,superestrogenism syndrome accounted for 17.82％,superandrogenic syndrome accounted for 12.87％,turner syndrome accounted for 10.89％,other aneuploidy abnormalities[including 48,XXXY:1 case;69,XXY(80％)/68,XXY,-22(20％):1 case]accounted for 1.98％,and chimerism accounted for 22.77％.The prenatal indications for 101 cases of SCA were as follows:age ≥ 35 years,high/critical risk of serum biochemical screening,fetal ultrasound abnormalities,abnormalities in non-invasive prenatal testing(NIPT),history of adverse pregnancy and childbirth and other reasons(1 case of cerebral palsy in pregnant women and 4 cases of bilateral thalassemia)accounted for 53.47％(54/101),4.95％(5/101),17.82％(18/101),51.49％(52/101),12.87％(13/101),4.95％(5/101),respectively.Partial cases had multiple prenatal diagnostic indications.Meanwhile,23 fetuses diagnosed with sex chromosome chimerism,of which 22 cases were validated by karyotype and CNV seq,11 pregnant women chose to terminate their pregnancy,with the rest chose to continue pregnancy.Conclusion The combination of prenatal karyotype diagnosis,serological testing,prenatal ultrasound and other prenatal screening methods can help improve the detection rate of SCA,while CNV-seq can provide more clinical evidence for genetic counseling of pregnant women with sex chromosome chimerism.
