OBJECTIVE: To investigate the clinical application value of artificial intelligence (AI)-based bone marrow cell recognition and analysis system in the diagnosis of hematological diseases. METHODS: The bone marrow smears of hematological patients who were admitted to The Second Hospital of Shanxi Medical University from 2018 to 2020 were retrospectively analyzed. A total of 115 bone marrow smears with clear diagnosis and typical cell morphology characteristics were selected, including 20 cases of immune thrombocytopenia(ITP), 11 cases of iron deficiency anemia (IDA), 17 cases of megaloblastic anemia (MA), 20 cases of chronic myeloid leukemia (CML), 17 cases of acute lymphoblastic leukemia (ALL), 23 cases of acute promyelocytic leukemia (APL), and 7 cases of acute myeloid leukemia unclassified (AML-M2). The samples were analyzed by manual microscopic examination, AI automatic recognition, and manual correction after AI recognition. RESULTS: The images captured by the AI device were clear, and the cell morphological structures were distinct. The average experimental diagnostic efficiency parameters of the bone marrow nucleated cells classified in this system were calculated. The sensitivity was 74.90%, specificity was 99.03%, and accuracy was 98.29%. In the comparison between the AI recognition group and the manual examination group, the data of IDA, ITP, MA, and CML diseases were all greater than 0.85 in ICC correlation coefficient, with excellent consistency; the data of APL, AML-M2, and ALL three diseases were between 0.6 and 0.85 in ICC correlation coefficient, with moderate consistency. However, after manual review and correction, the ICC correlation coefficient between the data of the AI correction group and the data from the manual examination group was greatly improved. CONCLUSION The AI bone marrow cell recognition and analysis system has the characteristics of high accuracy, high specificity, good sensitivity and fast detection. When used in combination with manual review, it can improve the detection efficiency of bone marrow cells morphological analysis and meet the needs of clinical work.

Liver involvement is often observed in hematological disorders, resulting in liver abnormality, including unconjugated hyperbilirubinemia, monoclonal hyperglobulinemia, portal vein, or hepatic vein thrombosis or portal hypertension, hepatosplenomegaly, or iron accumulation in the liver. Here we summarize the major hematological diseases that often affect the liver: hemolytic anemia, defect in coagulation or anti-coagulation factors, myeloproliferative neoplasm, hemophagocytic lymphohistiocytosis, multiple myeloma, leukemia, and lymphoma. We hope this review will help clinicians diagnose and manage the patients with liver involvement by hematological disorders.

Spontaneous chronic subdural hematoma (SDH) is a rare condition that could develop in association with hematologic disease. A 66-year-old male developed a chronic SDH as an initial manifestation of chronic myelomonocytic leukemia (CMML). He experienced recurrent chronic subdural hemorrhage and newly developed intracerebral hemorrhage. Considering the scheduled long-term chemotherapy, bilateral middle meningeal artery (MMA) embolization was performed to prevent recurrence of subdural hemorrhage. Although pancytopenia occurred during the 7 months' follow-up period, residual chronic subdural hemorrhage was absorbed without recurrence. To our best knowledge, this is the first report of CMML with spontaneous chronic SDH. MMA embolization is potentially a useful and safe treatment option in the challenging clinical situations with underlying pathologies.

Mitochondria are important intracellular organelles that produce energy for cellular development, differentiation, and growth. Mitochondrial DNA (mtDNA) presents a 10- to 20-fold higher susceptibility to genetic mutations owing to the lack of introns and histone proteins. The mtDNA repair system is relatively inefficient, rendering it vulnerable to reactive oxygen species (ROS) produced during ATP synthesis within the mitochondria, which can then target the mtDNA. Under conditions of chronic inflammation and excess stress, increased ROS production can overwhelm the antioxidant system, resulting in mtDNA damage. This paper reviews recent literature describing the pathophysiological implications of oxidative stress, mitochondrial dysfunction, and mitochondrial genome aberrations in aging hematopoietic stem cells, bone marrow failure syndromes, hematological malignancies, solid organ cancers, chronic inflammatory diseases, and other diseases caused by exposure to environmental hazards.

INTRODUCTIONThis study aimed to assess the kind of haematological abnormalities that are present in patients with mitochondrial disorders (MIDs) and the frequency of their occurrence.

METHODSThe blood cell counts of a cohort of patients with syndromic and non-syndromic MIDs were retrospectively reviewed. MIDs were classified as 'definite', 'probable' or 'possible' according to clinical presentation, instrumental findings, immunohistological findings on muscle biopsy, biochemical abnormalities of the respiratory chain and/or the results of genetic studies. Patients who had medical conditions other than MID that account for the haematological abnormalities were excluded.

RESULTSA total of 46 patients ('definite' = 5; 'probable' = 9; 'possible' = 32) had haematological abnormalities attributable to MIDs. The most frequent haematological abnormality in patients with MIDs was anaemia. 27 patients had anaemia as their sole haematological problem. Anaemia was associated with thrombopenia (n = 4), thrombocytosis (n = 2), leucopenia (n = 2), and eosinophilia (n = 1). Anaemia was hypochromic and normocytic in 27 patients, hypochromic and microcytic in six patients, hyperchromic and macrocytic in two patients, and normochromic and microcytic in one patient. Among the 46 patients with a mitochondrial haematological abnormality, 78.3% had anaemia, 13.0% had thrombopenia, 8.7% had leucopenia and 8.7% had eosinophilia, alone or in combination with other haematological abnormalities.

CONCLUSIONMID should be considered if a patient's abnormal blood cell counts (particularly those associated with anaemia, thrombopenia, leucopenia or eosinophilia) cannot be explained by established causes. Abnormal blood cell counts may be the sole manifestation of MID or a collateral feature of a multisystem problem.

The inflammasome is a group of multiprotein complexes in the cytoplasm, which can activate caspase-1 that mediates the maturation and release of IL-1β, IL-18, IL-33 and other pro-inflammatory cytokines.NALP1 (NACHT leucine-rich-repeat protein 1), also known as NLRP1, is the first one of the identified complex inflammasomes with definite ligands mainly involved in the activation of inflammasome assembly and the formation of apoptotic bodies. Moreover, it was also found that NLRP1 plays an important biological role in the development of acute leukemia, the bone marrow hematopoietic stem cell apoptosis and other blood diseases. This review briefly summarizes the structure, activation mechanism, regulation and the role of NLRP1 in the hematopoietic system.

This study evaluated the toxicity profiles of temozolomide in the treatment of malignant glioma as either concurrent or adjuvant chemotherapy. We retrospectively reviewed the medical records of 300 malignant glioma patients treated with temozolomide in two medical institutions in Korea between 2004 and 2010. Two hundred nine patients experienced a total of 618 toxicities during temozolomide therapy. A total of 84.8% of the 618 toxicities were Common Terminology Criteria for Adverse Events (CTCAE) grade 1 or 2, while 15.2% were grade 3 or 4. Among the hematologic toxicities, thrombocytopenia (13.7%), anemia (11.0%), and AST/ALT increases (7.0%) were common. Among the non-hematologic toxicities, nausea (44.3%), vomiting (37.0%), and anorexia (14.3%) were the three most common toxicities. There was no mortality due to temozolomide. Although temozolomide showed many types of toxicities, the majority of the toxicities were tolerable and of lower grade. Gastrointestinal troubles are the most common toxicities in Korean patients treated with temozolomide.

Small ubiquitin-related modifier (SUMO) can be covalently attached to target proteins and thereby plays a crucial role in regulating the normal functions of cells, such as protein-protein interaction, subcellular localization, DNA repair, cell cycle and transcription factor regulation. Several lines have implicated that sumoylation is important in disease occurrence and development. This brief review will focus on some recent findings about the roles of sumoylation in the etiology and treatment of hematological malignancies.
