Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

OBJECTIVE: To explore the risk and location of multiple malignancies in patients with hematologic malignancies who were followed up for 9 years in Jiangsu Province Hospital and to evaluate the impact of the second primary malignancy on survival of patients. METHODS: The incidence and survival of multiple malignancies in 7 921 patients with hematologic malignancies from 2009 to 2017 were analyzed retrospectively. RESULTS: A total of 180 (2.3%, 180/7 921) patients developed second malignancy, of whom 58 patients were diagnosed with hematologic malignancies as the first primary malignancy, and 98 patients developed hematologic malignancies as second primary malignancy, and the other 24 cases were diagnosed with the second malignancy within 6 months after the first primary malignancy was diagnosed, which was difined as multiple malignancies occurring simultaneously. In 180 patients, 18 cases developed two hematologic malignancies successively, and 11 patients developed more than 3 primary cancers (among them, 2 female patients were diagnosed with 4 primary cancers). Patients with lymphoma and multiple myeloma (MM) as the second primary malignancy had poorer survival than patients with lymphoma and MM as the first primary malignancy. Patients with chronic myeloid leukemia as the second primary malignancy were also associated with inferior overall survival. CONCLUSION In this study, 2.3% of hematologic malignancy patients had multiple mali-gnancies, lymphoma and MM as the second primary malignancy had poor survival.

OBJECTIVE: To investigate the risk factors and prognosis of cardiovascular damage in hypereosinophilia (HE). METHODS: The clinical data of 62 patients with HE in Gansu Provincial Hospital from January 2015 to December 2020 were retrospectively analyzed, including clinical characteristics and laboratory indicators, and the influencing factors of survival and prognosis were also analyzed. RESULTS: In this study, there were 34 males and 28 females, with a median age of 53.5 (20-79) years, 35 patients without cardiovascular damage, 27 patients with cardiovascular damage, including 22 patients with abnormal electrocardiogram (ECG) (81.5%), 18 patients with abnormal echocardiography (ECHO) (66.7%), 9 patients with single ECG abnormality, 5 patients with single ECHO abnormality, and other 13 patients with multiple abnormalities. In cardiovascular damage group, peripheral white blood cell count, absolute value of eosinophils, troponin T (TNT), N-terminal pro-B-type natriuretic peptide (NT-proBNP), interleukin (IL)-4 and IL-5 levels at initial diagnosis were significantly higher than those in the non-cardiovascular damage group (P <0.01), while hemoglobin, IL-2 and interferon-γ levels were significantly lower (P <0.01). There were no significant differences in age, sex, course of disease, etiological classification, platelet count, serum creatine kinase, serum creatine kinase isoenzyme and lactate dehydrogenase between the two groups (P >0.05). The 5-year overal survival rate of patients with cardiovascular damage was 88.9%, and that of patients without cardiovascular damage was 100%, the difference was statistically significant (P =0.012). The 5-year event-free survival (EFS) rate of patients with cardiovascular damage was 59.3%, and the median time was 37 (21-52) months, while that of patients without cardiovascular damage was 80%, and the median time was 63 (51-74) months (P =0.002). Age (>60 years old), course of disease (>24 months), NT-proBNP (>3 000 pg/ml), TNT (>100 ng/L), elevated IL-4 and IL-5 were associated with EFS shortening in patients with cardiovascular damage, which were independent risk factors for EFS. CONCLUSION The EFS rate in HE patients without cardiovascular damage is significantly higher than patients with cardiovascular damage. Age, course of disease, NT-proBNP, TNT, IL-4 and IL-5 are independent risk factors affecting EFS of patients with cardiovascular damage.

Multiple myeloma (MM) is a malignant proliferative disease of plasma cells. Bone marrow mesenchymal stem cells (MSC) play an important role in the progression of MM. Compared with normal donor derived MSC (ND-MSC), MM patients derived MSC (MM-MSC) exhibit abnormalities in genes, signaling pathways, protein expression levels and cytokines secreted by themselves. Moreover, the exosomes of MM-MSC can interact with the bone marrow microenvironment. The above reasons can lead to MM cell proliferation, chemoresistance, impaired osteogenic differentiation of MM-MSC, and affect the immunomodulatory capacity of MM patients. In order to further understand the pathogenesis and related influencing factors of MM, this paper reviews the latest research progress of MM-MSC.

OBJECTIVE: To investigate the clinical characteristics, diagnosis, and treatment of one patient with TAFRO syndrome, and to strengthen the understanding of this rare type. METHODS: The clinical manifestations, diagnosis and treatment process, and prognosis of the patient admitted in Gansu Provincial People's Hospital were retrospectively analyzed. RESULTS: Combined with laboratory tests, bone marrow examination, imaging, pathology, etc, the patient was diagnosed with TAFRO syndrome. After three cycles of treatment with pomalidomide (2-3 mg/d, d1-21), cyclophosphamide (300 mg/m², 0.54 g once a week) and dexamethasone (20 mg/d, two days a week), platelet count, serum creatinine and procalcitonin returned to normal, the systemic edema disappeared, and the patient's condition was alleviated. The therapeutic effect was good. CONCLUSION TAFRO syndrome is rare, involves multiple systems, progresses rapidly, and has a worse prognosis. The choice of the "Pomalidomide+cyclophosphamide+dexamethasone" regimen is help to improve the survival prognosis of patient with TAFRO syndrome.

OBJECTIVE: To observe the expression level of serum homocysteine (Hcy) and methylenetetrahydrofolate reductase (MTHFR) gene polymorphism in patients with hematological diseases complicated with coronary heart disease, and analyze the relationship between serum Hcy level, MTHFR gene polymorphism and coronary heart disease. METHODS: The medical records of 80 patients with coronary heart disease who completed treatment of hematological diseases during the period from March 2018 to March 2020 were selected as observation group. In addition, the medical records of 92 patients with hematological diseases who completed treatment in our hospital during the same period were selected as control group. Venous blood samples of the two groups were collected to detect serum Hcy level and MTHFR gene polymorphism. The serum Hcy levels of the two groups with different MTHFR genotypes were compared, and the effects of the above indicators on hematological diseases complicated with coronary heart disease were analyzed. RESULTS: The detection rates of MTHFR gene TT and TC in the observation group were higher than those in the control group, while the distribution frequency of MTHFR genotype CC was lower (P<0.05). The serum Hcy levels of the patients with MTHFR genotype TT and TC in the observation group was higher than the control group (P<0.05). Binary logistic regression analysis showed that MTHFR gene TC/CC genotype serum Hcy overexpression may be influencing factor which induced coronary heart disease in patients with hematological diseases (OR=2.107/OR=1.634, P<0.05). ROC curves showed that the AUC of serum Hcy level of MTHFR gene TC/CC genotype and hematological disease complicated with coronary heart disease were both > 0.8. When MTHFR gene TC reaching the optimal threshold of 22.165 μmol/L, the sensitivity was 0.950 and the specificity was 0.837, While MTHFR gene CC reached the optimal threshold of 19.630 μmol/L, the sensitivity was 0.938 and the specificity was 0.826, the best predictive value could be obtained. CONCLUSION The changes of serum Hcy and MTHFR gene polymorphisms may be involved in the pathological process in patients with hematological diseases complicated with coronary heart disease. In the future, early detection of serum Hcy levels and MTHFR gene polymorphisms in patients with hematological diseases can be used to predict the risk of coronary heart disease.

OBJECTIVE: To analyze the clinical characteristics of multiple myeloma(MM) patients with early relapse. METHODS: A total of 50 MM patients with early relapse (≤12 months) and 50 matched controls with late relapse (>12 months) were selected. The time from diagnosis to relapse and related clinical data of the 100 patients were retrospectively analyzed, and the factors associated with early relapse were identified. Kaplan-Meier curve was used to analyze the overall survival (OS) time of the whole cohort. Area under the curve (AUC) was used to evaluate the effect of circulating plasma cells on early recurrence of the patients. RESULTS: The results showed that high-risk cytogenetics (FISH) (P=0.005), and ISS stage III (P=0.008) were associated with early recurrence of the patients. For patients with early relapse, high-risk FISH showed poor survival. Compared with the patients with late relapse, most of the chromosome karyotype of patients with early relapse showed quantitative and structural abnormalities. The expression of circulating plasma cells was significantly increased in patients with early recurrence group (P=0.0318). The response to initial treatment was poor in the early recurrence group (P=0.001), and the prognosis was significantly worse than those in the late recurrence group (median OS: 38 vs 81 months, P=0.002). CONCLUSION Early relapse is a marker poor prognostic in MM patients, and such patients should be focused on the improving their prognosis.

OBJECTIVE: To observe the effects of drug-containing serum of Xijiao Dihuang combined prescription(XJDH) on the related functions of dendritic cells(DCs) induced in vitro, and to explore the mechanisms underlying the effectiveness of XJDH treatment on primary immune thrombocytopenia(ITP). METHODS: Peripheral blood samples were colle-ted from 6 healthy volunteers. Mononuclear cells were isolated by density gradient centrifugation, and CD14⁺ mononuclear cells were collected by the magnetic separation technique. CD14+ mononuclear cells were induced into immature DCs by recombinant human granulocyte-macrophage colony stimulating factor (GM-CSF) and recombinant human interleukin 4 (IL-4). Immature DCs were divided into three groups: control group, model group and XJDH group. CCK-8 assay was used to determine the intervention concentration and time of drug-containing serum. Lipopolysaccharide(LPS) with the final concentration of 1 μg/ml was added to model group and XJDH group respectively for 24 h to induce DCs maturation. Normal rat serum was added to control group and model group, and XJDH was added to XJDH group for 24 h. Flow cytometry was used to detect the levels of CD80, CD83 and HLA-DR on the surface of DCs. Western blot was used to detect the expression of TLR4 and NF-κB, and levels of IL-6, IL-12 and TNF-α in cell supernatant was detected by ELISA. RESULTS: Compared with the control group, LPS stimulation increased the expression of CD80, CD83 and HLA-DR, with subsequent increasing expression of TLR4 and NF-κB, as well as IL-6, IL-12 and TNF-α increased(P<0.05). In comparison with model group, the expression of DCs surface molecules CD80, CD83 and HLA-DR, DCs' expression of TLR4 and NF-κB protein, and the levels of IL-6, IL-12 and TNF-α in the cell supernatant of XJDH group decreased after the intervention of XJDH (P<0.05). CONCLUSION Drug containing serum of Xijiao Dihuang combined prescription can down-regulate TLR4/NF-κB signaling pathway related protein expression, inhibit DCs maturation, and reduce proinflammatory factor secretion, which may be one of the mechanisms of drug-containing serum of Xijiao Dihuang combined prescription in the treatment of immune thrombocytopenia.

Myelodysplastic syndrome (MDS) are a heterogeneous group of hematological malignancies. Currently, in addition to demethylated chemotherapy and hematopoietic stem cell transplantation, MDS patient-derived mesenchymal stem cells (MDS-MSC) play an important role in understanding the pathogenesis of MDS and related therapeutic targets. For example, abnormal expression of DICER1 gene, abnormalities of PI3K/AKT and Wnt/β-catenin signaling pathways provide new therapeutic targets for MDS. In addition, MDS-MSC is also affected by abnormal microenvironment of the body, such as inflammatory factor S100A9, as well as hypercoagulation and iron overload. In this review, genes, signaling pathways, cytokines, hematopoietic microenvironment, and the effect of therapeutic drugs for MDS-MSC were briefly summarized.
