Oligodendrocyte lineage cells, including oligodendrocyte precursor cells (OPCs) and oligodendrocytes (OLs), are essential in establishing and maintaining brain circuits. Autophagy is a conserved process that keeps the quality of organelles and proteostasis. The role of autophagy in oligodendrocyte lineage cells remains unclear. The present study shows that autophagy is required to maintain the number of OPCs/OLs and myelin integrity during brain aging. Inactivation of autophagy in oligodendrocyte lineage cells increases the number of OPCs/OLs in the developing brain while exaggerating the loss of OPCs/OLs with brain aging. Inactivation of autophagy in oligodendrocyte lineage cells impairs the turnover of myelin basic protein (MBP). It causes MBP to accumulate in the cytoplasm as multimeric aggregates and fails to be incorporated into integral myelin, which is associated with attenuated endocytic recycling. Inactivation of autophagy in oligodendrocyte lineage cells impairs myelin integrity and causes demyelination. Thus, this study shows autophagy is required to maintain myelin quality during aging by controlling the turnover of myelin components.

Objective:To analyze the clinical characteristics,treatment,and prognosis of adult patients with early T-cell precursor acute lymphoblastic leukemia/lymphoma(ETP-ALL/LBL).Methods:Clinical data of 113 T lymphoblastic leukemia/lymphoma(T-ALL/LBL)patients from January 2006 to January 2019 were collected from three hematology research centers,including Peking University Third Hospital,the First Medical Center of Chinese PLA General Hospital and Institute of Hematology and Blood Diseases Hospital,Chinese Medical University.The clinical characteristics and prognosis of ETP-ALL/LBL patients were analyzed compared with non-ETP-ALL/LBL patients.Results:In 113 T-ALL/LBL patients,13 cases(11.5％)were diagnosed as ETP-ALL/LBL,including 11 males,with a median age of 28(18-53)years.Compared with non-ETP-ALL/LBL patients,there were no significant differences in age,sex,incidence of large mediastinal mass,clinical stage,international prognostic index(IPI)score,white blood cell(WBC)count and lactate dehydrogenase(LDH)level among ETP-ALL/LBL patients.Among 13 ETP-ALL/LBL patients,9 cases(69.2％)achieved complete remission(CR),and there was no statistically significant difference in response rate induced by chemotherapy between ETP-ALL/LBL patients and non-ETP-ALL/LBL patients.Among patients who received chemotherapy without allogeneic hematopoietic stem cell transplantation(allo-HSCT),ETP-ALL/LBL group had a worse 5-year overall survival(OS)rate compared with non-ETP-ALL/LBL group(0 vs 7.1％,P=0.008),while in patients with allo-HSCT,there was no significant difference for 5-year OS rate between the two group(37.5％vs 40.2％,P＞0.05).Multivariate Cox regression analysis showed that CR after induction therapy,allo-HSCT,and LDH level were independent prognostic factors affecting T-ALL/LBL patients.Conclusion:No significant difference in response rate induced by chemotherapy is observed between ETP-ALL/LBL and non-ETP-ALL/LBL patients.Allo-HSCT consolidation after induction of remission therapy may have significant favorable influence on OS for patients with ETP-ALL/LBL.

Objective To systematically evaluate the efficacy and safety of three-dimensional visualization technology in assisting ablation therapy for hepatocellular carcinoma.Methods This study was conducted according to PRISMA guidelines,with a PROSPERO registration number of CRD42023488398.PubMed,Embase,Web of Science,the Cochrane Library,CNKI,Wanfang Data,VIP,and CBM were searched for Chinese and English articles on three-dimensional visualization technology in assisting ablation therapy for hepatocellular carcinoma published up to March 2023.After quality assessment and data extraction of the studies included,RevMan 5.4 software was used to perform the meta-analysis.Results A total of 11 studies were included,with 972 patients in total,among whom 447 underwent ablation assisted by three-dimensional visualization technology(3D group)and 525 underwent ablation assisted by traditional two-dimensional imaging technology(2D group).The meta-analysis showed that compared with the 2D group,the 3D group had significantly higher success rate of first-time ablation treatment(odds ratio[OR]=5.43,95%confidence interval[CI]:2.64—11.18,P<0.001),technical efficiency(OR=6.15,95%CI:3.23—11.70,P<0.001),and complete ablation rate(OR=2.50,95%CI:1.08—5.78,P=0.03),as well as significantly lower incidence rate of major complications(OR=0.45,95%CI:0.24—0.87,P=0.02),local recurrence rate(OR=0.35,95%CI:0.17—0.72,P=0.004),and local tumor progression rate(OR=0.29,95%CI:0.16—0.50,P<0.001),while there was no significant difference in the incidence rate of mild complications between the two groups(P>0.05).Conclusion Three-dimensional visualization technology is safe and feasible in assisting ablation therapy for hepatocellular carcinoma and can improve ablation rate and reduce the incidence rate of serious complications,local recurrence rate,and local tumor progression rate,thereby showing an important application value in clinical practice.
