OBJECTIVE: To analyze the efficacy and safety of decitabine-based myeloablative preconditioning regimen for allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with acute myeloid leukemia (AML). METHODS: The clinical characteristics and efficacy of 115 AML patients who underwent allo-HSCT at the First Medical Center of Chinese PLA General Hospital from August 2018 to August 2022 were retrospectively analyzed, including 37 patients treated with decitabine conditioning regimen (decitabine group) and 78 patients without decitabine conditioning regimen (non-decitabine group). The cumulative incidence of relapse (CIR), overall survival (OS), leukemia-free survival (LFS), non-relapse mortality (NRM) and graft versus host disease (GVHD) were analyzed. RESULTS: For the patients in first complete remission (CR1) state before allo-HSCT, the 1-year relapse rates of decitabine group(22 cases) and non-decitabine group(69 cases) were 9.1% and 29.6%, respectively, the difference was statistically significant(P =0.042). The 1-year cumulative incidence of acute graft-versus-host disease (aGVHD) in decitabine group and non-decitabine group was 62.2% and 70.5%, respectively, and the 1-year cumulative incidence of chronic inhibitor-versus-host disease (cGVHD) was 18.9% and 14.1%, respectively, there were no significant differences in the incidence of aGVHD and cGVHD between the two groups (P >0.05). Of the 115 patients, there were no significantly differences in the 1-year CIR(21.7% vs 28.8%, P =0.866), NRM(10.9% vs 3.9%, P =0.203), OS(75.2% vs 83.8%, P =0.131) and LFS(74.6% vs 69.1%, P =0.912) between the decitabine group(37 cases) and the non-decitabine group(78 cases). CONCLUSION Decitabine-based conditioning regimen could reduce the relapse rate of AML CR1 patients with good safety.

OBJECTIVE: To explore the clinical characteristics and prognosis of children with SIL-TAL1-positive T-cell acute lymphoblastic leukemia ( SIL-TAL1⁺ T-ALL). METHODS: The clinical data of 110 children with newly diagnosed T-ALL admitted to the pediatric department of our hospital from January 2010 to December 2018 were reviewed to compare the clinical characteristics, treatment response and prognosis between SIL-TAL1⁺ group and SIL-TAL1^-group. RESULTS: Among the 110 children with T-ALL, 25 cases (22.7%) were in the SIL-TAL1⁺ group and 85 cases (77.3%) in the SIL-TAL1^- group. The white blood cell (WBC) count in the SIL-TAL1⁺ group was significantly higher than that in the SIL-TAL1^- group (P < 0.05), while the other clinical characteristics and treatment response were not significantly different between the two groups. The 5-year overall survival (OS) rates of SIL-TAL1⁺ group and SIL-TAL1^- group were 80.0% and 75.5%, and 5-year disease-free survival (DFS) rates were 76.0% and 72.9%, respectively. There were no significant differences in OS rate and DFS rate between the two groups ( P >0.05). In children aged < 10 years, the 5-year OS rate of SIL-TAL1⁺ group and SIL-TAL1^- group was 100% and 75.1%, respectively, and the difference between the two groups was statistically significant (P < 0.05). CONCLUSION Although the WBC level is significantly higher in children with SIL-TAL1⁺ T-ALL than that in those with SIL-TAL1^- T-ALL, the treatment efficacy is similar between the two groups. In children aged < 10 years, the longterm survival rate is superior in the SIL-TAL1⁺ group.

OBJECTIVE: Circadian rhythm disruption (CRD) is a risk factor that correlates with poor prognosis across multiple tumor types, including hepatocellular carcinoma (HCC). However, its mechanism remains unclear. This study aimed to define HCC subtypes based on CRD and explore their individual heterogeneity. METHODS: To quantify CRD, the HCC CRD score (HCCcrds) was developed. Using machine learning algorithms, we identified CRD module genes and defined CRD-related HCC subtypes in The Cancer Genome Atlas liver HCC cohort (n = 369), and the robustness of this method was validated. Furthermore, we used bioinformatics tools to investigate the cellular heterogeneity across these CRD subtypes. RESULTS: We defined three distinct HCC subtypes that exhibit significant heterogeneity in prognosis. The CRD-related subtype with high HCCcrds was significantly correlated with worse prognosis, higher pathological grade, and advanced clinical stages, while the CRD-related subtype with low HCCcrds had better clinical outcomes. We also identified novel biomarkers for each subtype, such as nicotinamide n-methyltransferase and myristoylated alanine-rich protein kinase C substrate-like 1. CONCLUSION We classify the HCC patients into three distinct groups based on circadian rhythm and identify their specific biomarkers. Within these groups greater HCCcrds was associated with worse prognosis. This approach has the potential to improve prediction of an individual's prognosis, guide precision treatments, and assist clinical decision making for HCC patients.

OBJECTIVE: Poxviruses are zoonotic pathogens that infect humans, mammals, vertebrates, and arthropods. However, the specific role of ticks in transmission and evolution of these viruses remains unclear. METHODS: Transcriptomic and metatranscriptomic raw data from 329 sampling pools of seven tick species across five continents were mined to assess the diversity and abundance of poxviruses. Chordopoxviral sequences were assembled and subjected to phylogenetic analysis to trace the origins of the unblasted fragments within these sequences. RESULTS: Fifty-eight poxvirus species, representing two subfamilies and 20 genera, were identified, with 212 poxviral sequences assembled. A substantial proportion of AT-rich fragments were detected in the assembled poxviral genomes. These genomic sequences contained fragments originating from rodents, archaea, and arthropods. CONCLUSION Our findings indicate that ticks play a significant role in the transmission and evolution of poxviruses. These viruses demonstrate the capacity to modulate virulence and adaptability through horizontal gene transfer, gene recombination, and gene mutations, thereby promoting co-existence and co-evolution with their hosts. This study advances understanding of the ecological dynamics of poxvirus transmission and evolution and highlights the potential role of ticks as vectors and vessels in these processes.

Objective To explore the efficacy of early hyperbaric oxygen therapy(HBOT)combined with median nerve electrical stimulation(MNES)in the treatment of severe traumatic brain injury(sTBI)and its impact on hemodynamics,coma degree,and neurological function of patients.Methods A total of 78 patients with sTBI admitted to the General Hospital of Western Theater Command from March 2020 to October 2021 were selected as the research subjects.The patients were randomly divided into the control group and the observation group,with 39 patients in each group.The patients in both groups underwent basic treatments such as water,electrolyte and acid-base balance,nutritional support,anti-infection,and decompressive craniectomy.On this basis,patients in the control group received early HBOT,while patients in the observation group received both HBOT and MNES.Their clinical efficacy was compared between the two groups.Before and after treatment,dual-channel transcranial Doppler ultrasound was performed to detect hemodynamic indicators such as peak systolic blood flow velocity(Vs),mean blood flow velocity(Vm),and pulsatility index(PI)in the middle cerebral artery of patients in the two groups.The Glasgow Coma Scale(GCS)score was used to evaluate the degree of coma of patients in the two groups,the National Institutes of Health Stroke Scale(NIHSS)score was used to assess the neurological deficits of patients in the two groups,and the enzyme-linked immunosorbent assay was used to measure the levels of central nervous system specific protein(S100-β),glial fibrillary acidic protein(GFAP),and myelin basic protein(MBP).Complications during treatment of patients in the two groups were recorded,and their incidence was compared.Results The total effective rate of patients in the control and observation groups was 79.49％(31/39)and 92.31％(36/39),respectively.The total effective rate in the observation group was significantly higher than that in the control group(x2=8.971,P＜0.05).There was no significant difference in Vm,Vs,and PI between the two groups before treatment(P＞0.05).After treatment,the Vm and Vs in both groups were significantly higher than those before treatment,while the PI was significantly lower than that before treatment(P＜0.05);and the Vm and Vs in the observation group were signifi-cantly higher than that those in the control group,while the PI was significantly lower than that in the control group(P＜0.05).There was no significant difference in GCS and NIHSS scores between the two groups before treatment(P＞0.05).After treatment,the GCS score in both groups was significantly higher than that before treatment,while the NIHSS score was significantly lower than that before treatment(P＜0.05);and the GCS score in the observation group was significantly higher than that in the control group,while the NIHSS score was significantly lower than that in the control group(P＜0.05).There was no significant difference in S100-β,GFAP,and MBP levels between the two groups before treatment(P＞0.05).After treatment,the S100-β,GFAP,and MBP levels in both groups were significantly lower than those before treatment(P＜0.05),and the S100-β,GFAP,and MBP levels in the observation group were significantly lower than those in the control group(P＜0.05).During treatment,the incidence of complications in the control and observation groups was 23.08％(9/39)and 20.51％(8/39),respectively,showing no significant difference(x2=2.328,P＞0.05).Conclusion Early HBOT combined with MNES shows good efficacy in treating sTBI,which can effectively improve the patients'hemodynamic level,alleviate the severity of coma,enhance neurological function,and promote early recovery of consciousness,without increased risk of complications.

Objective To investigate the effect of the HtrA serine peptidase 3(HTRA3)gene on choroidal neovascu-larization(CNV)and M2 macrophage polarization.Methods Fasting venous blood was collected from 30 patients with wet age-related macular degeneration(wAMD group)and 30 healthy subjects(normal group).The serum HTRA3 messen-ger ribonucleic acid(mRNA)level was detected by quantitative reverse transcription polymerase chain reaction(qRT-PCR).RF/6A cells were randomly divided into the control group,NC-sh group and HTRA3-sh group.Lentiviral vectors of NC-shRNA and HTRA3-shRNA were transfected into RF/6A cells in the NC-sh group and HTRA3-sh group by Lipo-fectamine2000.HTRA3 transfection was detected by qRT-PCR and Western blot.Then,the RF/6A cells were randomly di-vided into the N group,H group,H+NC-sh group and H+HTRA3-sh group.After cell transfection,RF/6A cells in the N group were cultured in a RPMI 1640 complete medium at a normoxia state,and cells in other groups were cultured in a RP-MI 1640 medium with 200 mmol·L-1 CoCl2 at a hypoxia state.Tubule formation was measured by Matrigel.The C57BL/6J mice were divided into the control group,CNV group,CNV+NC-sh group and CNV+HTRA3-sh group,with 12 mice in each group.Mice in the control group were unmodeled mice,and mice in the other groups were laser-induced CNV model mice.NC-shRNA and HTRA3-shRNA lentiviral vectors with a titer of 1 × 1011 TU·mL-1 were administered to mice in the CNV+NC-sh group and CNV+HTRA3-sh group via intravitreal injection.Mice in the control group and CNV group were in-jected with phosphate buffered saline.After 7 days of treatment,the mice were examined by fundus fluorescein angiogra-phy,and the eyeballs received hematoxylin & eosin staining.The mRNA levels of HTRA3,chitinase-like protein 3(Ym-1),arginase 1(Arg-1),inducible nitric oxide synthase(iNOS),cyclooxygenase-2(COX-2)and vascular endothelial growth factor(VEGF)in RF/6A cells or choroidal tissues were detected by qRT-PCR.The protein expression levels of HTRA3,VEGF and nuclear factor kappa B(NF-κB)p65 in RF/6A cells or choroidal tissues were detected by Western blot.Re-sults Compared with the normal group,serum HTRA3 mRNA level of patients in the wAMD group increased(t=11.804,P＜0.001).Compared with the control group and NC-sh group,the expressions of HTRA3 mRNA and protein in RF/6A cells in the HTRA3-sh group decreased(all P＜0.05).Compared with the N group,the number of closed lumen and the mRNA and protein expressions of HTRA3 and VEGF in RF/6A cells in the H group increased(all P＜0.05).Compared with the H+NC-sh group,the number of closed lumen and the mRNA and protein expressions of HTRA3 and VEGF decreased in RF/6A cells in the H+HTRA3-sh group(all P＜0.05).Compared with the control group,the mRNA and protein expression levels of HTRA3 increased,the relative fluorescence intensity of CNV increased,the mRNA levels of Ym-1 and Arg-1 in-creased,the iNOS and COX-2 mRNA levels decreased,and the NF-κB p65 protein expression level increased in mice of the CNV group(all P＜0.05).Compared with the CNV+NC-sh group,the mRNA and protein expression levels of HTRA3 de-creased,the relative fluorescence intensity of CNV decreased,the mRNA levels of Ym-1 and Arg-1 decreased,the mRNA levels of iNOS and COX-2 increased,and the NF-κB p65 protein expression level decreased in mice of the CNV+HTRA3-sh group(all P＜0.05).Conclusion Down-regulation of HTRA3 can inhibit the formation of CNV and the polarization of M2 macrophages.HTRA3 may be an important potential target for the prevention and treatment of wAMD.

Objective:To investigate the efficacy and safety of Venetoclax combined with CACAG regimen in treatment of patients with refractory/relapse acute myeloid leukemia(R/R AML).Methods:The study was a singlecenter prospective clinical trial.The enrolled patients met the criteria for R/R AML.Treatment included Azacidine(75mg/m2,d1-7),Ara-C(75-100 mg/m2,q12h,d1-5),Aclacinomycin(20 mg d1,d3,d5),Chidamide(30 mg d1,d4),Venetoclax(100 mg d1,200 mg d2,400 mg d3-d14,in combination with Triazole Drug,reduced to 100 mg/d),and granulocyte colony-stimulating factor(300 μg/d until neutrophil recovery).The primary endpoint of observation was overall response rate after 1 course of treatment.Results:A total of 19 patients were enrolled from January 2022 to April 2023.After 1 course of treatmen,the overall response rate was 81.3％(13/16),the CR rate was 68.8％(11/16),and the PR was 12.5％(2/16).Among the 11 patients who got CR/CRi,8 cases achieved CRm(minimal residual disease negative CR)and 3 cases did not.As of March 27,2023,the median follow-up time was 111(19-406)days.The six-month overall survival and progression-free survival rates were both 55.7％,the 1-year overall survival and progression-free survival rates were 46.4％and 47.7％,respectively.In addition,compared with the non-CRm group,CRm patients had a better PFS(377 days vsi11 days,P=0.046).Treatment-related adverse events were mainly 3-4 degrees of bone marrow suppression,complicated by various degrees of infection(n=12),hypokalemia(n=12)and hypocalcemia(n=10)and elevated liver enzymes(n=8),of which 3/4 degrees accounted for 47.4％(9/19).Conclusion:The Venetoclax combined with CACAG regimen is an effective salvage therapy for patients with R/R AML,with high remission rate and safety profile.

Objective:To investigate the relationship between IGF2BP3 gene expression and prognosis in patients with acute myeloid leukemia(AML).Methods:High throughput transcriptome sequencing was performed on bone marrow primary leukemia cells from 27 patients with AML in our center,the relationship between IGF2BP3 expression levels and clinical characteristics were analyzed and verify the samples from patients with newly treated AML and refractory AML.The expression level of IGF2BP3 gene were analyzed in 20 healthy subjects and 26 patients with AML.The expression of IGF2BP3 in two anthracycline-resistant cell lines(HL60/ADR,K562/ADR)was detected by RT-qPCR and Western blot,and the expression difference of IGF2BP3 was compared with that in sensitive cells(HL60,K562).The relationship between the expression level of IGF2BP3 in patients with AML and prognostic were analyzed through data analysis of 746 patients with AML,and the prognostic value of IGF2BP3 in AML was analyzed by multivariate Cox regression analysis.Results:In the bone marrow primary leukemia cells of 27 AML patients in our center,the expression level of IGF2BP3 in patients with refractory AML was significantly higher than that in chemotherapy sensitive patients(P=0.0343).The expression of IGF2BP3 in leukemia patients with extramedullary infiltration(EMI)was significantly higher than that in AML patients without extramedullary infiltration(P=0.0049).Compared with healthy subjects(n=20),IGF2BP3 expression in AML patients(n=26)was higher(P=0.0009).The expression of IGF2BP3 mRNA in the anthracycline resistant cell lines(HL60/ADR,K562/ADR)was significantly higher than that in the sensitive cell lines(K562/ADR vs K562,P=0.0430;HL60/ADR vs HL60,P=0.7369).Western blot results showed that the expression of IGF2BP3 protein in mycin resistant cells was significantly higher than that in sensitive cells(P＜0.001).qPCR results showed that the expression level of IGF2BP3 mRNA in refractory AML patients was significantly higher than that in patients with chemotherapy sensitive(P=0.002).High expression of IGF2BP3 was associated with poor prognosis in AML(P＜0.05)in 3 large sample cohorts of AML patients.Univariate and multivariate prognostic analyses demonstrated that high expression of IGF2BP3 was significantly associated with shorter event-free survival(EFS,HR=1.887,P=0.024)and overall survival(OS,HR=1.619,P=0.016).Conclusion:The high expression of IGF2BP3 gene may be an important factor in the poor prognosis of AML,suggesting that IGF2BP3 gene may be a new molecular marker for the clinical prognosis evaluation and treatment strategy of AML.

Objective:To explore the plasma metabolomic characteristics of children with transfusion-dependent thalassemia(TDT),and reveal the changes of metabolic pattern in children with TDT.Methods:23 children with TDT who received regular blood transfusion in Ganzhou Women and Children's Health Care Hospital in 2021 were selected,and 11 healthy children who underwent physical examination during the same period were selected as the control group.The routine indexes between children with TDT and the control group were compared,and then the metabolic composition of plasma samples from children with TDT and the control group was detected by liquid chromatography-mass spectrometry.An OPLS-DA model was established to perform differential analysis on the detected metabolites,and the differential metabolic pathways between the two groups were analyzed based on the differential metabolites.Results:The results of routine testing showed that the indexes of ferritin,bilirubin,total bile acid,glucose and triglycerides in children with TDT were significantly higher than those in healthy controls,while hemoglobin and total cholesterol were significantly lower(all P＜0.05).However there was no significant difference in lactate dehydrogenase between the two groups(P＞0.05).Compared with the control group,190 differential metabolites(VIP＞1)were identified in TDT children.Among them,168 compounds such as arginine,proline and glycocholic acid were significantly increased,while the other 22 compounds such as myristic acid,eleostearic acid,palmitic acid and linoleic acid were significantly decreased.The metabolic pathway analysis showed that the metabolic impact of TDT on children mainly focused on the upregulation of amino acid metabolism and downregulation of lipid metabolism.Conclusion:The amino acid and lipid metabolism in children with TDT were significantly changed compared with the healthy control group.This finding is helpful to optimize the treatment choice for children with TDT,and provides a new idea for clinical treatment.

Objective To analyze the clinical characteristics of high energy metabolism in lung cancer patients and its correlation with body composition,nutritional status,and quality of life,and to develop a corresponding risk prediction model.Methods Retrospectively analyzed 132 primary lung cancer patients admitted to the First Hospital of Shanxi Medical University from January 2022 to May 2023,and categorized into high(n=94)and low energy metabolism group(n=38)based on their metabolic status.Differences in clinical data,body composition,Patient Generated Subjective Global Assessment(PG-SGA)scores,and European Organization for Research and treatment of Cancer(EORTC)Quality of Life Questionnaire-Core 30(QLQ-C30)scores were compared between the two groups.Logistic regression was used to identify the risk factors for high energy metabolism in lung cancer patients,and a risk prediction model was established accordingly;the Hosmer-Lemeshow test was used to assess the model fit,and the ROC curve was used to test the predictive efficacy of the model.Results Of the 132 patients with primary lung cancer,94(71.2%)exhibited high energy metabolism.Compared with low energy metabolism group,patients in high-energy metabolism group had a smoking index of 400 or higher,advanced disease staging of stage Ⅲ or Ⅳ,and higher levels of IL-6 level,low adiposity index,low skeletal muscle index,and malnutrition(P<0.05),and lower levels of total protein,albumin,hemoglobin level,and prognostic nutritional index(PNI)(P<0.05).There was no significant difference in age,gender,height,weight,BMI and disease type between the two groups(P>0.05).Logistic regression analysis showed that smoking index≥400,advanced disease stage,IL-6≥3.775 ng/L,and PNI<46.43 were independent risk factors for high energy metabolism in lung cancer patients.The AUC of the ROC curve for the established prediction model of high energy metabolism in lung cancer patients was 0.834(95%CI 0.763-0.904).Conclusion The high energy metabolic risk prediction model of lung cancer patients established in this study has good fit and prediction efficiency.
