Objective:To investigate the therapeutic efficacy of autologous hematopoietic stem cell transplantation (auto-HSCT) for treatment of diffuse large B-cell lymphoma (DLBCL) and the factors affecting the prognosis.Methods:A retrospective case series study was conducted. The clinical data of 51 patients with DLBCL who underwent auto-HSCT in the First Affiliated Hospital of Xinjiang Medical University from March 2019 to January 2024 were retrospectively analyzed. Patients were divided into high-risk group (19 cases) and non-high-risk group (low-risk, low-moderate-risk and moderate-high-risk groups, 32 cases) based on different risk stratifications; patients were divided into the germinal center B-cell (GCB) group (29 cases) and non-GCB group (22 cases) based on different cellular origins; patients were divided into BEAM group (39 cases) and BeEAM group (12 cases) based on different conditioning regimens before auto-HSCT; patients were divided into auto-HSCT consolidation therapy group (41 cases) and auto-HSCT after relapsed/refractory group (10 cases) based on different transplantation timings. The Kaplan-Meier method was used for survival analysis and log-rank was used for subgroup comparison.Results:All 51 patients achieved the hematopoietic reconstitution with no transplantation-related death within 100 d. Before auto-HSCT, 39 cases achieved complete remission and 12 cases (23.5%) achieved partial remission. After auto-HSCT, all cases achieved complete remission. Follow-up was until May 31, 2024, and the median follow-up time [ M ( Q1, Q3)] of 51 DLBCL patients was 33 (8, 43) months. After 51 DLBCL patients receiving auto-HSCT, 7 patients relapsed and 6 cases died including 3 cases with relapse-related death and 3 cases with non relapse-related death. The 3-year progression-free survival (PFS) and overall survival (OS) rates were 78.5% (95% CI: 64.4%-92.6%) and 85.5% (95% CI: 73.2%-97.8%), respectively. The 3-year PFS rate was 94.7% (95% CI: 84.7%-104.7%) in the high-risk group, 82.2% (95% CI: 67.9%-96.5%) in the non-high-risk group, and the difference in the PFS was not statistically significant between the high-risk group and the non-high-risk group ( P = 0.158). The 3-year PFS rate was 80.1% (95% CI: 64.4%-95.8%) in the GCB group, 88.1% (95% CI: 72.3%-104.2%) in the non-GCB group, and the difference in PFS was not statistically significant between the 2 groups ( P = 0.803). The 3-year PFS rate was 84.9% (95% CI: 72.6%-97.2%) in BEAM group, 61.1% (95% CI: 25.0%-97.2%) in the BeEAM group, and the difference in PFS was not statistically significant between the 2 groups ( P = 0.106). The 3-year PFS rate was 85.4% (95% CI: 73.4%-97.4%) in the auto-HSCT consolidation therapy group, 64.3% (95% CI: 31.4%-96.4%) in the auto-HSCT after relapsed/refractory group, and the difference in PFS was not statistically significant between the 2 groups ( P = 0.171). Conclusions:auto-HSCT is an effective therapy method for DLBCL.

Objective To investigate the clinical efficacy of peripheral blood stem cell transplantation from haploidentical and matched sibling donors for treatment of high-risk and refractory/relapsed acute myeloid leukemia (AML). Methods Data on the efficacy of haploidentical peripheral blood stem cell transplantation (Haplo-HSCT) with myeloablative conditioning regimen were retrospectively analyzed and compared with that of matched sibling donors' peripheral blood stem cell transplantation (MSD-HSCT) for treatment of high-risk refractory/relapsed AML in our center from January 1st, 2010 to June 30th, 2020. Results A total of 98 patients were enrolled, including 62 patients in the Haplo-HSCT group and 36 patients in MSD-HSCT group. The median age, conditioning regimen, and infusion doses of MNC and CD34+ cells were significantly different between the two groups, but no significant differences in other baseline parameters were found. Transplantation-related infectious complications and the incidence of acute and chronic graft-versus-host disease (GVHD) were also not significantly different between the two groups. The 3-year cumulative relapse in the Haplo-HSCT group was significantly lower than that in the MSD-HSCT group (16.2% vs. 41.1%, P=0.036). The 3-year DFS of the Haplo-HSCT and MSD-HSCT groups were 66.98% and 41.8%, respectively (P=0.140), and their OS were 73.37% and 51.41%, respectively (P=0.105). Conclusion The clinical efficacy of Haplo-HSCT for the treatment of high-risk and refractory/relapsed AML is similar to that of MSD-HSCT, and Haplo-HSCT may have better GVL effect.

Objective:To investigate the clinical efficacy of high-dose non-T-cell depleted peripheral blood stem cells (PBSC) used as grafts in haploidentical hematopoietic stem cell transplantation with reduced intensity conditioning (RIC-haplo-HSCT) in the treatment of elderly patients with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS).Methods:The clinical data of AML or MDS 28 patients aged ≥50 years who underwent RIC-haplo-HSCT in the First Affiliated Hospital of Xinjiang Medical University from January 2014 to June 2022 were retrospectively analyzed. All patients received high-dose non-T-cell depleted PBSC as grafts. Anti-CD25 monoclonal antibody and glucocorticoid were added as intensive graft-versus-host disease (GVHD) prophylaxis.Results:All patients achieved hematopoietic reconstruction. The accumulative incidence of grade Ⅱ-Ⅳ and Ⅲ-Ⅳ acute GVHD within 100 d was 22.5% (95% CI 5.1%-39.9%) and 8.2% (95% CI 0-19.2%), respectively. The 3-year cumulative incidence of chronic GVHD was 26.8% (95% CI 7.8%-45.8%), and the incidence of extensive chronic GVHD was 5.9% (95% CI 0-17.1%). The median follow-up time was 35.5 (2-83) months. The 3-year cumulative incidence of relapse and non-relapse mortality was 16.7% (95% CI 2.0%-31.9%) and 12.2% (95% CI 0-25.2%), respectively. The 3-year disease-free survival and overall survival rates were 73.3% (95% CI 56.2%-90.4%) and 79.1% (95% CI 62.2%-96.0%), respectively. Conclusions:High-dose non-T-cell depleted PBSC used as grafts for RIC-haplo-HSCT can achieve good clinical efficacy in elderly patients with AML/MDS.

Objective:To explore the pathogenic genes, clinical characteristics and treatment follow-up of children with congenital long QT syndrome (LQTS).Methods:Clinical data of 20 cases diagnosed with congenital LQTS and underwent gene testing from April 15, 2011 to April 15, 2021 in Department of Pediatric Cardiology, Shandong Provincial Hospital Affiliated to Shandong University were retrospectively collected and analyzed using independent sample t-test and Fisher′ s exact probability method. Results:LQTS-related gene mutations were detected in all the 20 cases, and pathogenic or suspected pathogenic mutations were identified in 18 cases (90.0%). Five LQTS mutation genes were discovered, including KCNQ1, KCNH2, SCN5A, CACNA1C and AKAP9.Eighteen cases (90.0%) had positive symptoms, and 13 cases (65.0%) had definite inducements.The inducement of symptoms in children with LQTS type 1(LQT1) was related to exercise, the causes of syncope in LQT1 and Jervell-Lange-Nielsen syndrome type 1 (JLNS1) with complex heterozygous mutations were exercise or emotional agitation; the causes of syncope in LQTS type 2 (LQT2) were unrelated to exercise; severe exercise in LQTS type 3 (LQT3) resulted in symptoms; and seizure in LQTS type 8 (LQT8) was non-induced.The corrected QT(QTc) interval of 20 cases was (553.1±66.6) ms, with a range of 460-707 ms, among which 17 cases showed QTc≥480 ms.The electrocardiogram(ECG) manifestations of children with various types of LQTS were different.There was no significant difference in QTc between different genders, or between children with syncope and those without syncope (all P>0.05). The follow-up time was (3.4±2.3) years, ranging from 0 to 8.3 years.Seventeen children received treatment[beta blockers and implantable cardiovertor-defibrillator(ICD)] and 3 cases did not.By the end of the follow-up, 1 child died, 19 cases survived, and 2 cases of the surviving children lost consciousness. Conclusions:There is a high consistency between genetic diagnosis and clinical diagnosis of congenital LQTS.The positive rate of gene detection is 90.0%.The clinical manifestations and ECG characteristics vary with genotypes.Beta blockers are protective.ICD therapy can prevent sudden cardiac death when oral medication does not respond.
