OBJECTIVE: To investigate the efficacy and safety of diagnostic-driven therapy for invasive fungal disease(IFD) in patients with myeloid hematologic malignancies. METHODS: A retrospective analysis was conducted on the clinical data of 91 patients with myeloid hematologic malignancies who received diagnostic-driven therapy for IFD at the Second Hospital of Anhui Medical University from January 1, 2020 to December 31, 2023. The patients were divided into two groups based on medication: 44 patients in the caspofungin group and 47 patients in the voriconazole group. The clinical efficacy and adverse reactions of the two groups were compared and analyzed. RESULTS: The overall response rates in the caspofungin and voriconazole groups were 67.4% and 60.0%, respectively. Among patients who transitioned to diagnostic-driven therapy following prophylactic or empirical treatment with triazole antifungal agents, the response rate of the caspofungin group was significantly higher than that of the voriconazole group (76.9% vs 35.3%, P <0.05). A total of 9 patients in both groups experienced adverse reactions, and no grade III or higher adverse reactions occurred. The incidence of grade I-II adverse reactions in the caspofungin group was lower than in the voriconazole group (2.3% vs 17.0%, P <0.05). CONCLUSION In patients with myeloid hematologic malignancies, caspofungin and voriconazole demonstrate comparable clinical efficacy in diagnostic-driven therapy for IFD, but caspofungin is associated with a lower incidence of adverse reactions. Caspofungin exhibits significant effectiveness when initiating diagnostic-driven therapy after prophylactic or empirical treatment with broad-spectrum triazole antifungal agents.

OBJECTIVE: To investigate the effect of recombinant human granulocyte colony stimulating factor (rhG-CSF) on the clinical efficacy and flow cytometry (FCM) minimal residual disease (MRD) of patients with acute myeloid leukemia (AML) after initial induction therapy in the real world. METHODS: The clinical data of 44 AML patients who were diagnosed for the first time in the Department of Hematology, The Second Hospital of Anhui Medical University, and received the initial induction therapy were retrospectively analyzed. According to whether rhG-CSF was used after treatment, these patients were divided into control group and therapy group. The complete remission (CR) rate, duration of neutropenia, incidence of infection, duration of fever, cost of antibiotics drugs, length of hospital stay, FCM MRD, and relapse-free survival (RFS) time were compared between the two groups. RESULTS: The CR rate in the control group was 60%, and 74% in the therapy group (P=0.3429). The duration of neutropenia was (21.28±7.91) days in the control group and (14.79±3.07) days in the therapy group (P=0.0016). The duration of fever was (12.80±7.31) days in the control group and (9.11±7.48) days in the therapy group (P=0.0136). While, there were no statistically significant differences between the two groups in the incidence of infection, cost of antibacterial drugs, length of hospital stay and RFS time (all P>0.05). In addition, it is particularly noteworthy that among the patients who finally obtained CR in the therapy group, 66% of them had myeloid precursor cells detected by peripheral blood FCM (accounting for 2.25%±0.99%) at the time of the first release of neutropenia, which was easy to be misdiagnosed as MRD positive. CONCLUSION rhG-CSF not only don't affect the clinical remission rate after the initial induction treatment of AML, but also significantly shortens the time of duration of neutropenia and fever, however, it may affect the analysis of peripheral blood FCM MRD detection results when the neutropenia is released for the first time.

Objective: To analyze the clinical characteristics of children with Burkitt lymphoma (BL) and to summarize the mid-term efficacy of China Net Childhood Lymphoma-mature B-cell lymphoma 2017 (CNCL-B-NHL-2017) regimen. Methods: Clinical features of 436 BL patients who were ≤18 years old and treated with the CNCL-B-NHL-2017 regimen from May 2017 to April 2021 were analyzed retrospectively. Clinical characteristics of patients at disease onset were analyzed and the therapeutic effects of patients with different clinical stages and risk groups were compared. Survival analysis was performed by Kaplan-Meier method, and Cox regression was used to identify the prognostic factors. Results: Among 436 patients, there were 368 (84.4%) males and 68 (15.6%) females, the age of disease onset was 6.0 (4.0, 9.0) years old. According to the St. Jude staging system, there were 4 patients (0.9%) with stage Ⅰ, 30 patients (6.9%) with stage Ⅱ, 217 patients (49.8%) with stage Ⅲ, and 185 patients (42.4%) with stage Ⅳ. All patients were stratified into following risk groups: group A (n=1, 0.2%), group B1 (n=46, 10.6%), group B2 (n=19, 4.4%), group C1 (n=285, 65.4%), group C2 (n=85, 19.5%). Sixty-three patients (14.4%) were treated with chemotherapy only and 373 patients (85.6%) were treated with chemotherapy combined with rituximab. Twenty-one patients (4.8%) suffered from progressive disease, 3 patients (0.7%) relapsed, and 13 patients (3.0%) died of treatment-related complications. The follow-up time of all patients was 24.0 (13.0, 35.0) months, the 2-year event free survival (EFS) rate of all patients was (90.9±1.4) %. The 2-year EFS rates of group A, B1, B2, C1 and C2 were 100.0%, 100.0%, (94.7±5.1) %, (90.7±1.7) % and (85.9±4.0) %, respectively. The 2-year EFS rates was higher in group A, B1, and B2 than those in group C1 (χ²=4.16, P=0.041) and group C2 (χ²=7.21, P=0.007). The 2-year EFS rates of the patients treated with chemotherapy alone and those treated with chemotherapy combined with rituximab were (79.3±5.1)% and (92.9±1.4)% (χ²=14.23, P<0.001) respectively. Multivariate analysis showed that stage Ⅳ (including leukemia stage), serum lactate dehydrogenase (LDH)>4-fold normal value, and with residual tumor in the mid-term evaluation were risk factors for poor prognosis (HR=1.38,1.23,8.52,95%CI 1.05-1.82,1.05-1.43,3.96-18.30). Conclusions: The CNCL-B-NHL-2017 regimen show significant effect in the treatment of pediatric BL. The combination of rituximab improve the efficacy further.

To investigate the clinical features and prognostic significance in myelodysplastic syndrome (MDS) patients with DTA (DNMT3A,TET2,ASXL1) mutations. Clinical characteristics of 140 patients diagnosed as de novo MDS at People′s Hospital of Xinjiang Uygur Autonomous Region from September 2015 to December 2019 were retrospectively analyzed. Next-generation sequencing was used to detect 34 related genes in MDS patients. DTA mutations and the correlation with progression-free survival (PFS) and overall survival (OS) in MDS patients were evaluated. Among 140 MDS patients, DTA mutations was detected in 62 (44.3%) patients. And the positive rate of DTA mutations in IPSS-R lower-risk group was 65.4%, significantly higher than that of higher-risk group (31.8%)( P=0.000). Compared with the non-mutated group, patients with DTA mutations had a lower rate of conversion to leukemia (9.7% vs . 29.5%, P=0.004).Survival analysis showed that PFS in patients with DTA mutations was comparable as that in MDS patients without DTA mutations ( P=0.787), but the median OS was significantly shorter (16 months vs . 20 months, P=0.022).According to IPSS-R classification, the median OS in patients with and without DTA mutation was only statistically significant in the higher-risk group (15 months vs. 18 months, P=0.034).Among 62 patients with DTA mutations, 60 (96.8%) had additional gene mutations. DTA mutations were not independent prognostic factors when mutation frequency is greater than 10% were considered in Cox regression model ( P>0.05). DTA mutations often developed in the early stage of MDS, therefore they were more common in IPSS-R lower-risk subgroup which was correlated to the low rate of conversion to leukemia. In conclusion, DTA mutations are not associated with disease progression, but predict unfavorable survival when other add-on genes are mutated.

OBJECTIVE: To explore the influencing factors and countermeasures of infection in leukemia patients after allogeneic peripheral blood hematopoietic stem cell transplantation. METHODS: A total of 126 patients with leukemia admitted in our hospital from August 2016 to March 2018 were selected. The number of infected patients after transplantation was recorded, and the causes of infection were analyzed. RESULTS: Among the 126 patients, 43 were positive for infection, and the infection rate was 34.13%. A total of 89 pathogens were detected, of which bacteria accounted for 64.05%; virus accounted for 22.47%, and fungi accounted for 13.48%. The patient's age, donor type, pre-transplant infection, prophylactic use of antibiotics and aGVHD all were factors influencing the patient's infection (P＜0.05). The follow-up results showed that the incidence of infection in the intervention group significantly decreased after intervention with prevention program (P＜0.05). After reasonable nursing intervention, the incidence of infection in the intervention group after follow-up for 12 months was lower than that in the control group (P＜0.05). CONCLUSION Pre-transplant infection and prophylactic use of antibiotics are factors influencing the infection after allogeneic hematopoietic stem cell transplantation. The incidence of infection can be reduced by reasonable infection prevention.

OBJECTIVE: To study the Polymorphism of the human platelet antigen(HPA) gene 1-17 and human leukocyte antigen(HLA) gene-A and B locus in Shandong Han population. METHODS: A total of 962 samples from routine voluntary platelet donors were genotyped for HPA1-17 system and HLA-A site, B by PCR-SSP and PCR-SSOP respectively．Gene frequencies were calculated by counting. HPA1-17 and HLA genotype combinations were analyzed by Arelequin 3.5. RESULTS: The gene frequencies of HPA-la, -1b, HPA-2a, -2b, HPA-3a, -3b, HPA-4a, -4b, HPA-5a, -5b, HPA-6a, -6b, HPA-15a, -15b were 0.9918, 0.0082, 0.9419, 0.0592, 0.5841, 0.4174, 0.9969, 0.0031, 0.9892, 0.0108, 0.9835, 0.0175,0.5488 and 0.4512, respectively． The most common HPA genotype combination was HPA-(1, 2, 4, 5, 6, 7-14, 16, 17) aa-3ab-15ab (0.2048). Moreover, HLA-A*2(0.3094) and HLA-B*13(0.1513) showed the highest frequency in their respective locus. The most common HLA genotype combination was HLA-A*2-B*13(0.1397) . CONCLUSION Distributions of HPA and HLA show high polymorphism in Shandong Han population. The ethnic and territorial difference of HPA distribution is also confirmed. It is imperative to establish local genetic database of volunteer platelet donors.

Objective: To investigate the predictive value of N-terminal type B natriuretic peptide（NT-proBNP) on the prognosis of elderly hospitalized patients without heart failure（non-heart failure). Method: Elderly patients aged 65 years or older, who were admitted to Beijing Hospital from September 2018 to February 2019, were enrolled in this study. Patients with clinical diagnosis of heart failure or left ventricular ejection fraction（LVEF)<50% were excluded. The patients were divided into 2 groups based on the serum NT-proBNP level: low NT-proBNP group （<125 ng/L) and high NT-proBNP group（≥125 ng/L). Patients were followed up at 3, 6, and 12 months after enrollment, and the major adverse events were recorded. The composite endpoint events included all-cause mortality, readmission or Emergency Department visits. Cardiovascular events include death, readmission or emergency room treatment due to cardiogenic shock, myocardial infarction, angina pectoris, arrhythmia, heart failure or stroke/transient ischemic attack. Results: A total of 600 elderly patients with non-heart failure were included in the analysis. The average age was （74.9±6.5) years, including 304（50.7%) males. The median follow-up time was 344（265, 359) days. One hundred and seventy-eight（29.7%) composite endpoint events were recorded during the follow-up, 19（3.2%) patients died, and 12（2.0%) patients were lost to follow-up. There were 286(47.7%) cases in low NT-proBNP group and 314 cases（52.3%) in high NT-proBNP group. Patients were older, prevalence of atrial fibrillation and myocardial infarction was higher; MMSE scores and ADL scores, albumin and creatinine clearance rate were lower in high NT-proBNP group than in low NT-proBNP group（all P<0.05). At 1-year follow-up, the incidence of composite endpoint events was significantly higher in high NT-proBNP group than in low NT-proBNP group（33.4%（105/314) vs. 24.8%（71/286), P = 0.02). Cardiovascular events were more common in high NT-proBNP group than in low NT-proBNP group（17.5%（55/314) vs. 8.4%（24/286), P = 0.001). Kaplan-Meier survival analysis showed both composite endpoint events（Log-rank P=0.016) and cardiovascular events（Log-rank P=0.001) were higher in high NT-proBNP group than in low NT-proBNP group. All-cause mortality was also significantly higher in highNT-proBNP group than in lowNT-proBNP group（4.8%（15/314) vs. 1.4%（4/286), P = 0.020), and Kaplan-Meier survival analysis demonstrated borderline statistical significance（Log-rank P = 0.052). Cox proportional hazard regression analysis showed that after adjusting for age, sex, creatinine clearance rate, myocardial infarction, and atrial fibrillation, NT-proBNP remained as an independent risk factor for composite endpoint events（HR=1.376，95%CI 1.049-1.806, P=0.021), and cardiovascular events（HR=1.777, 95%CI 1.185-2.664, P=0.005), but not for all-cause mortality（P=0.206). Conclusions: NT-proBNP level at admission has important predictive value on rehospitalization and cardiovascular events for hospitalized elderly non-heart failure patients. NT-proBNP examination is helpful for risk stratification in this patient cohort.

OBJECTIVE: To investigate the hypothesis that hydrogen could ameliorate cecal ligation and puncture (CLP)-induced lung injury of rats by inhibiting cystathionine-gamma-lyase/hydrogen sulfide (CSE/HS) system. METHODS: A total number of 24 healthy male SD rats weighting 250～300 g were randomly divided into four groups (n=6 in each group): sham operation group(sham group), hydrogen-rich saline control group(H group), CLP group and hydrogen-rich saline treatment group(CLP+H group). The rats were treated with hydrogen-rich saline or saline 10 min before CLP or sham operation. At 8 h of sham or CLP operation, lung samples were obtained to detect the changes of the CSE/HS system using biochemical and RT-PCR methods. In order to further confirm the role of HS during hydrogen improve the lung injury of CLP rats, we also observed the effect of hydrogen-rich saline on the lung injury induced by HS donor-sodium sodium hydrosulfide (NaHS). Thirty-two healthy male SD rats (250~300 g) were randomly divided into four groups (n=8 in each group): control group, HS group, HS+H group and H group. Saline(10 mg/kg) or NaHS(HS donor, 56 μmol/kg) was injected intraperitoneally (10 mg/kg) respectively into rats in the control rats or HS group. For rats in the HS+H and H group, hydrogen-rich saline (10 mg/kg) was injected 10 min before saline or NaHS administration. Eight hours after the LPS saline or NaHS administration, lung coefficient, MDA content, and MPO activity were detected. The contents of TNF-α, IL-6 and IL-10 in lung tissue were measured, and the morphological changes of lung tissue were also observed. RESULTS: CSE/HS system up-regulating were observed in animals exposed to CLP. Hydrogen-rich saline treatment significantly inhibited CSE/HS system as indicated by significantly reduced HS production in lung, along with a decreased CSE activity and CSE mRNA expression (all P＜0.05). Importantly, the results showed that lung injury and lung tissue inflammation were observed in animals exposed to NaHS. Hydrogen-rich saline treatment significantly attenuated lung injury as indicated by significantly improved histological changes in lung, significantly reduced index of quantitative assessment (IQA), MDA content and lung coefficient (all P＜0.05). MPO activity in lung tissue was significantly reduced along with decreased productions of TNF-α and IL-6, and an increased production of IL-10 in the presence of hydrogen (all P＜0.05), demonstrating antioxidant and anti-inflammatory effect of hydrogen in NaHS-induced ALI. CONCLUSION These results indicate that hydrogen-rich saline peritoneal injection improves the lung injury induced by CLP operation. The therapeutic effects of hydrogen-rich saline may be related to suppressing the production of HS.

OBJECTIVEWe aim to explore the potential association between serum gamma-glutamyl transferase levels and functional outcome after aneurysmal subarachnoid hemorrhage in a Chinese population.

METHODSA total of 386 aneurysmal subarachnoid hemorrhage patients were included in the study from September 2007 to February 2015. Baseline serum gamma-glutamyl transferase levels and 6-month follow-up functional outcomes were determined. A poor outcome was defined as a modified ranking scale score of ⋝ 3. The multivariable logistic model was used to analyze the relationship between serum gamma-glutamyl transferase and clinical outcomes after aneurysmal subarachnoid hemorrhage.

RESULTSThe adjusted poor outcome rates of patients with gamma-glutamyl transferase levels of < 30 U/L, 30-50 U/L and ⋝ 50 U/L were 16.7%, 19.6%, and 34.4%, respectively (P < 0.01). The age-sex and multivariable adjusted odds ratios (95% confidence intervals) of poor prognosis comparing the top group (⋝ 50 U/L) with the lowest group (< 30 U/L) were 5.76 (2.74-12.13), 6.64 (2.05-21.52), and 6.36 (1.92-21.02). A significant linear trend existed between gamma-glutamyl transferase level and aneurysmal subarachnoid hemorrhage prognosis. This association was also observed among nondrinkers.

CONCLUSIONPatients with higher gamma-glutamyl transferase levels were more likely to have a poor prognosis. Serum gamma-glutamyl transferase can be considered to be an independent predictor of functional outcomes after aneurysmal subarachnoid hemorrhage.
