Blood has historically held symbolic importance in various cultures, with early medical observations dating back to Hippocrates and Galeno. The discovery of cells and subsequent advancements in microscopy by scientists like Hooke and van Leeuwenhoek paved the way for understanding blood cell morphology. Influential figures such as Hewson, Donné, and Ehrlich followed. Diagnostic cytology evolved from manual cell counting to the development of automated hematological systems. Automated complete blood counting came to support microscopic examination in diagnosing hematological disorders. Morphology is crucial in predicting disease outcomes and guiding treatment decisions, particularly hematological neoplasms. The introduction of flow cytometry and its integration with traditional morphological analysis and the new cytogenetic and molecular techniques revolutionized the classification and prognostication of hematologic disorders. Digital microscopy has emerged as a powerful tool in recent years, offering rapid acquisition and sharing of blood cell images. Integrating Artificial Intelligence with digital microscopy has further enhanced morphological analysis, improving diagnostic efficiency. We also discuss the prospects of AI in pre-classifying blood cells in bone marrow aspirate samples, potentially revolutionizing diagnostic pathways for hematologic diseases.

The major diagnostic criteria of the guidelines for T-PLL diagnosis&lt;span&gt;&lt;sup&gt;2&lt;/sup&gt;&lt;/span&gt; include: (1) 5 × 10&lt;sup&gt;9&lt;/sup&gt;/L cells of the T-PLL phenotype in peripheral blood or bone marrow (BM); (2) T-cell clonality determined via PCR or flow cytometry (FCM); and, (3) an abnormal 14q32 or Xq28 karyotype or expression of &lt;i&gt;TCL1A/B&lt;/i&gt; or &lt;i&gt;MTCP1&lt;/i&gt;. Additionally, four minor criteria also contribute to the diagnostic framework: (1) abnormalities involving chromosome 11 (11q22.3; &lt;i&gt;ATM&lt;/i&gt;); (2) abnormalities involving chromosome 8 such as idic(8)(p11), t(8;8), trisomy 8q; (3) abnormalities in chromosomes 5, 12, 13, 22, or a complex karyotype; and, (4) T-PLL-specific features (e.g., splenomegaly, effusions). A diagnosis of T-PLL is established if all three major criteria are met or if the first two such criteria and at least one minor criterion are met. Obviously, analysis of chromosomal abnormalities is essential for diagnosis of T-PLL. However, T-PLL poses a challenge in this regard given the low proliferation capacity of mature T lymphocytes, leading to a high failure rate of chromosomal karyotyping associated with conventional culture methods (short-term culture).&lt;/p&gt;&lt;p&gt;In this study, we retrospectively analyze and present five cases for whom we used a phytohemagglutinin (PHA)-stimulated culture method to increase the detection rate of chromosomal abnormalities in BM cells.

Besides, DESeq2 was applied for differential expression analysis on AML samples and screening for differentially expressed genes (DEGs). The screened DEGs were subjected to the intersection analysis with ferroptosis-related genes to identify the ferroptosis-related DEGs. Next, the functional pathways of ferroptosis-related DEGs were further be discussed by Gene Ontology as well as Kyoto Encyclopedia of Genes and Genomes enrichment analysis of DEGs. Additionally, lasso regression analysis was employed to determine the differential genes related to prognosis in patients with AML and the survival analysis was performed. Subsequently, quantitative real-time polymerase chain reaction and western blot assay were applied to detect the mRNA and protein expression levels of HSPB1 in normal/AML bone marrow tissues and human normal (HS-5)/AML (HL-60) bone marrow cells, respectively. Furthermore, HSPB1 was knocked down to assess the expression changes of glutathione peroxidase 4 and acyl-CoA synthetase long-chain family member 4. Ultimately, the viability and oxidative stress levels of HL-60 were analyzed by Cell Counting Kit-8 and biochemical detection.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Results&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;A total of 4986 DEGs were identified in AML samples, with 3324 up-regulated and 1662 down-regulated. The enrichment analysis illustrated that ferroptosis-related DEGs were significantly enriched in response to metal irons, oxidative stress, and other pathways. After lasso regression analysis, 17 feature genes related to the prognosis of patients with AML were obtained, with HSPB1 exhibiting a significant correlation. The reliability of our models was verified by Cox regression analysis and survival analysis of the hazard model. Furthermore, the outcomes of quantitative real-time polymerase chain reaction and western blot showed that mRNA and protein expression levels of HSPB1 were significantly increased in the AML Group and HL-60 cells. The knockdown of HSPB1 in HL-60 cells reduced the protein level of glutathione peroxidase 4, increased the protein level of acyl-CoA synthetase long-chain family member 4, decreased the cell viability, and aggravated oxidative stress.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Conclusion&lt;/h3&gt;\u0000 ","PeriodicalId":14120,"journal":{"name":"International Journal of Laboratory Hematology","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2024-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141201589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
