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 comprehensively assess the current status of extrauterine growth restriction (EUGR) in very preterm infants (VPI) and its associated factors in Chinese neonatal intensive care units (NICU). Methods: In this cohort study, 6 179 preterm infants born at <32 weeks' gestation were included, who were admitted to 57 hospitals in the China Neonatal Network in 2019 and hospitalized for ≥7 days. EUGR was evaluated by a cross-sectional definition (weight at discharge<10th percentile for postmenstrual age), a longitudinal definition (decline in weight Z score>1 from birth to discharge), and weight growth velocity. The comparison between infants with and without EUGR was conducted by t-test, Mann-Whitney U test or χ2 test as appropriate. Multivariable Logistic regression models were used to evaluate associations between EUGR with different definitions and maternal and neonatal factors, clinical practices, and neonatal morbidities. Results: A total of 6 179 VPI were enrolled in the study, with a gestational age of (29.8±1.5) weeks and birth weight of (1 365±304) g; 56.2% (3 474) of them were male. Among them, 48.4% (2 992 VPI) were cross-sectional EUGR and 74.9% (4 628 VPI) were longitudinal EUGR. Z score of weight was (0.13±0.78) at birth and decrease to (-1.35±0.99) at discharge. The weight growth velocity was 10.13 (8.42, 11.66) g/(kg·d). Multivariate Logistic regression analysis showed that among the influential factors that could be intervened after birth, late attainment of full enteral feeds (ORadjust=1.01, 95%CI 1.01-1.02, P<0.001; ORadjust=1.01, 95%CI 1.01-1.02, P<0.001), necrotizing enterocolitis≥Ⅱstage (ORadjust=2.64, 95%CI 1.60-4.35, P<0.001; ORadjust=1.62, 95%CI 1.10-2.40, P<0.001) and patent ductus arteriosus (ORadjust=1.94, 95%CI 1.50-2.51, P<0.001; ORadjust=1.63, 95%CI 1.29-2.06, P<0.001) were all associated with increased risks of both cross-sectional and longitudinal EUGR. In addition, late initiation of enteral feeds (ORadjust=1.06, 95%CI 1.02-1.09, P=0.020) and respiratory distress syndrome (ORadjust=1.45, 95%CI 1.24-1.69, P<0.001) were all associated with cross-sectional EUGR. Breast milk feeding (ORadjust=1.33, 95%CI 1.05-1.68, P<0.001) was associated with a higher risk of longitudinal EUGR. Conclusions: The incidence of EUGR in VPI in China is high. Some modifiable risk factors provide priorities to improve postnatal growth for VPI. Nutritional management of VPI and the efforts to decrease the incidence of complications are still the focus of clinical management in China.

ObjectiveTo compare the outcomes in controlled ovarian stimulation (COH) and fresh embryo transfer between women with and those without a high basal luteinizing hormone (bLH) level in polycystic ovary syndrome (PCOS). MethodsThe clinical data of PCOS patients at the Reproductive Medicine Center of the Sixth Hospital of Sun Yat-sen University from January 2015 to December 2021 were retrospectively analyzed. They were divided into the high group (LH≥10 U/L) and normal group (LH<10 U/L) according to the bLH levels. The results of COH and pregnancy outcomes after fresh transfer were compared, including gonadotropin (Gn) initiation dose, Gn duration, total Gn dose, number of oocytes obtained, two pronuclei (2PN) rate, available embryos rate, high-quality embryos rate, blastocyst formation rate, human chorionic gonadotrophin (HCG) positive rate, clinical pregnancy rate (CPR), spontaneous abortion rate (SAR), ongoing pregnancy rate (OPR) and live birth rate (LBR). The differences in hormonal trends during COH were also analyzed. ResultsThere were no statistically significant differences in age, body mass index, anti-Mullerian hormone, and type of infertility between the two groups. Compared with the normal group, the Gn initiation dose and Gn duration were not statistically significant (P>0.05), while the total Gn dose was significantly lower (P<0.001) in the high group. The number of oocytes retrieved, 2PN rate, available embryos rate, high-quality embryos rate, and blastocyst formation rate were comparable between the two groups (all P>0.05). After fresh embryo transfer, they had similar pregnancy outcomes in the HCG positive rate, CPR, SAR, OPR and LBR (all P > 0.05). ConclusionsIn patients with PCOS, high bLH levels do not affect COH or pregnancy outcomes in fresh transfer cycles. Further studies are needed to determine whether LH levels need to be lowered prior to COH and whether frozen-all strategy is required in patients with elevated bLH levels.

OBJECTIVE:
To analyze the gene mutation profile in children with acute lymphocyte leukemia (ALL) and to explore its prognostic significance.
METHODS:
Clinical data of 249 primary pediatric ALL patients diagnosed and treated in the Department of Hematological Oncology of Wuhan Children's Hospital from January 2018 to December 2021 were analyzed retrospectively. Next-generation sequencing (NGS) was used to obtain gene mutation data and analyze the correlation between it and the prognosis of children with ALL.
RESULTS:
227 (91.2%) were B-ALL, 22 (8.8%) were T-ALL among the 249 cases, and 178 (71.5%) were found to have gene mutations, of which 85 (34.1%) had ≥3 gene mutations. NRAS(23.7%), KRAS (22.9%),FLT3(11.2%), PTPN11(8.8%), CREBBP (7.2%), NOTCH1(6.4%) were the most frequently mutated genes, the mutations of KRAS, FLT3, PTPN11, CREBBP were mainly found in B-ALL, the mutations of NOTCH1 and FBXW7 were mainly found in T-ALL. The gene mutation incidence of T-ALL was significantly higher than that of B-ALL (χ2= 5.573,P<0.05) and were more likely to have co-mutations (P<0.05). The predicted 4-year EFS rate (47.9% vs 88.5%, P<0.001) and OS rate (53.8% vs 94.1%, P<0.001) in children with tp53 mutations were significantly lower than those of patients without tp53 mutations. Patients with NOTCH1 mutations had higher initial white blood cell count (128.64×109/L vs 8.23×109/L,P<0.001), and children with NOTCH1 mutations had a lower 4-year EFS rate than those of without mutations (71.5% vs 87.2%, P=0.037).
CONCLUSION
Genetic mutations are prevalent in childhood ALL and mutations in tp53 and NOTCH1 are strong predictors of adverse outcomes in childhood ALL, with NGS contributing to the discovery of genetic mutations and timely adjustment of treatment regimens.

OBJECTIVE:
To investigate the mechanism of drug reversing resistance of Agaricus blazei extract FA-2-b-β on T cell acute lymphoblastic leukemia (T-ALL) cell lines.
METHODS:
Cell proliferation was detected by CCK-8 assay; the apoptosis, cell cycle mitochondrial membrane potential, and intracellular rhodamine accumulation were detected by flow cytometry, and apoptosis-related gene and protein expression were detected by qPCR and Western blot; the membrane surface protein MDR1 was observed by immunofluorescence microscopy.
RESULTS:
Different concentrations of FA-2-b-β significantly inhibited proliferation and induced apoptosis of CCRF-CEM and CEM/C1 (P<0.05), and CCRF-CEM cell cycle were arrested at S phase, and CEM/C1 cells were arrested at G0/G1 phase. Western blot and qPCR results show that FA-2-b-β inhibited ABCB1、ABCG2、CTNNB、MYC and BCL-2 expression, but upregulated Bax expression. In addition, FA-2-b-β reversed the resistance characteristics of CEM/C1 drug-resistance cells, which decreased mitochondrial membrane potential, and significantly increased the intracellular rhodamine accumulation, and weakening of the expression of the membrane surface protein MDR1. With the Wnt/β-catenin inhibitor (ICG001), the process was further intensified.
CONCLUSION
Agaricus Blazei Extract FA-2-b-β inhibits cell proliferation, promotes apoptosis, regulates the cell cycle, reduces mitochondrial energy supply, and down-regulate MDR1 expression to reverse the resistance of CEM/C1, which all suggest it is through regulating the Wnt signaling pathway in T-ALL.

OBJECTIVE:
To evaluate the clinical efficacy and safety of decitabine combined with modified CAG regimen (D-CAG regimen) in patients aged ≥70 years with newly diagnosed acute myeloid leukemia (AML).
METHODS:
The clinical data of 59 AML patients (≥70 years old) who were newly diagnosed and treated in the Hematology Department of the First Affiliated Hospital of Nanjing Medical University from November 2010 to June 2021 were retrospectively analyzed.
RESULTS:
Among the 59 AML patients, 28 were males and 31 were females, with a median age of 74 (70-86) years. The complete remission (CR) rate was 69.4% (34/49), and the median duration of CR was 10.7 (0.6-125.4) months after 2 courses of D-CAG treatment. According to the British Medical Research Council (MRC) classification, there was only one patient in the favorable-risk group, and the CR rate was 71.8% (28/39) in the intermediate-risk group, and 55.6% (5/9) in the adverse-risk group, respectively. There was no statistical difference in the CR rate between the intermediate-risk and adverse-risk group. Referring to ELN 2017 genetic risk classification, CR rate was 88.2% (15/17) in the favorable-risk group, 45.5% (5/11) in the intermediate-risk group, and 66.7% (14/21) in the adverse-risk group. There was no significant difference in CR rate between the favorable-risk and adverse-risk categories, but both were significantly higher than that in the intermediate-risk group (P <0.05). Next-generation sequencing (NGS) analysis showed that 11 gene mutations with a frequency of more than 10%, including TET2 mutation (35.6%), ASXL1 mutation (30.5%), NPM1 mutation (28.8%), FLT3-ITD mutation (27.1%), DNMT3A mutation (22.0%), IDH1 mutation (15.3%), CEBPA single mutation (13.6%), TP53 mutation (13.6%), IDH2 mutation (11.9%), RUNX1 mutation (11.9%), and NRAS mutation (10.2%). There were no statistical differences in mutation frequency of these 11 genes between CR group and non-CR group. Compared with normal karyotypes, patients with complex karyotypes were more likely to develop TP53 mutations (P <0.001), while FLT3-ITD and DNMT3A mutations were more likely to occur in patients with normal karyotypes (P =0.04, P =0.047). The median follow-up, overall survival (OS), and event-free survival (EFS) of all the patients was 11.7 (1.5-128.2) months, 12.3 (1.5-128.2) months, and 8.5 (1.5-128.2) months, respectively. The median OS and EFS of CR patients were 19.8 and 13.3 months, respectively, which were significantly longer than 6.4 and 5.7 months in patients experiencing treatment failure (P < 0.001, P =0.009). In regard to genes with mutation frequency >10%, there were no statistical differences in CR rate, median OS, and median EFS between mutated and wild-type patients by Chi-square test and survival analysis. Univariate analysis showed that age, hemoglobin, lactate dehydrogenase, cytogenetics and CR were factors affecting prognosis, while multivariate analysis showed that only CR failure was an independent adverse prognostic factor for OS. The major adverse reactions to D-CAG regimen were grade 3-4 myelosuppression, pulmonary infection, and fever (infection focus was not identified).
CONCLUSION
D-CAG regimen is safe and effective in the treatment of AML patients ≥70 years old, and can partially improve the prognosis of elderly and high-risk patients.

OBJECTIVE:
To study the cerebrospinal fluid (CSF) status and prognosis value in patients with newly diagnosed acute lymphoblastic leukemia (ALL) by flow cytometry (FCM).
METHODS:
The clinical features of the 75 newly diagnosed ALL patients from September 2020 to December 2021 in our centre were retrospective analyzed, as well as the bone marrow (BM) and CSF minimal residual disease (MRD) data, and the CSF conventional cytology data. Central nervous system infiltration(CNSI) positive was as CSF MRD positive by FCM or leukemia cells detected by conventional cytology. The status of CSF were compared and analyzed by FCM and conventional cytology, the clinical features and the prognosis value of different CNSI status in these patients were analyzed.
RESULTS:
Among 75 newly diagnosed ALL, 16 cases (21%) with CNSI positive (CNSI+) were detected by FCM, while only 2 positive cases (3%) were detected by conventional cytology. The CNSI+ rate detected by FCM was significantly higher than conventional cytology(P<0.05). Compared with CNSI- ALL patients, the median age of CNSI+ ALL patients was significantly younger, and the median platelet count was significantly lower, the difference was statistically significant (P<0.05). Up to follow-up time (August 31, 2022), four ALL patients were died, including 3 patients were CNSI- and 1 patient was CNSI+. Furthermore, three cases were primary disease relapse, including 1 case was CNSI+. There was no significant difference in overall survival (OS) rate and relapse-free survival (RFS) rate of the patients with different CNSI status.
CONCLUSION
Compared with conventional cytology, FCM is a more sensitive assay to evaluate the central nervous system status in ALL patients. After active treatment, there was no significant difference in OS and RFS between patients with different CNSI status at diagnosis.

OBJECTIVE:
To establish an immune gene prognostic model of acute myeloid leukemia (AML) and explore its correlation with immune cells in bone marrow microenvironment.
METHODS:
Gene expression profile and clinical data of TCGA-AML were downloaded from TCGA database. Immune genes were screened by LASSO analysis to construct prognosis prediction model, and prediction accuracy of the model was quantified by receiver operating characteristic curve and area under the curve. Survival analysis was performed by Log-rank test. Enriched pathways in the different immune risk subtypes were evaluated from train cohort. The relationship between immune prediction model and bone marrow immune microenvironment was verified by flow cytometry in the real world.
RESULTS:
Patients with low-risk score of immune gene model had better prognosis than those with high-risk score. Multivariate analysis showed that the immune gene risk model was an independent prognostic factor. The risk ratio for AML patients in the training concentration was HR=24.594 (95%CI: 6.180-97.878), and the AUC for 1-year, 3-year, and 5-year overall survival rate was 0.811, 0.815, and 0.837, respectively. In addition, enrichment analysis of differential gene sets indicated activation of immune-related pathways such as cytokines and chemokines as well as autoimmune disease-related pathways. At the same time, real world data showed that patients with high immune risk had lower numbers of CD8+T cells and B lymphocytes compared with low immune risk patients.
CONCLUSION
We constructed a stable prognostic model for AML, which can not only predict the prognosis of AML, but also reveal the dysregulation of immune microenvironment.
