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 Studies on the relationship between iodine,vitamin A(VA),and vitamin D(VD)and thyroid function are limited.This study aimed to analyze iodine and thyroid-stimulating hormone(TSH)status and their possible relationships with VA,VD,and other factors in postpartum women. Methods A total of 1,311 mothers(896 lactating and 415 non-lactating)from Hebei,Zhejiang,and Guangxi provinces were included in this study.The urinary iodine concentration(UIC),TSH,VA,and VD were measured. Results The median UIC of total and lactating participants were 142.00 μg/L and 139.95 μg/L,respectively.The median TSH,VA,and VD levels in all the participants were 1.89 mIU/L,0.44 μg/mL,and 24.04 ng/mL,respectively.No differences in the UIC were found between lactating and non-lactating mothers.UIC and TSH levels were significantly different among the three provinces.The rural UIC was higher than the urban UIC.Obese mothers had a higher UIC and a higher prevalence of excessive TSH.Higher UICs and TSHs levels were observed in both the VD deficiency and insufficiency groups than in the VD-sufficient group.After adjustment,no linear correlation was observed between UIC and VA/VD.No interaction was found between vitamins A/D and UIC on TSH levels. Conclusion The mothers in the present study had no iodine deficiency.Region,area type,BMI,and VD may be related to the iodine status or TSH levels.

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.

The UK screening and treatment of retinopathy of prematurity(ROP)updated 2022 guidelines were developed by a multidisciplinary guideline development group from the Royal College of Paediatrics and Child Health and the Royal College of Ophthalmologists,following the standards of the National Institute for Health and Care Excellence.They were published on the websites of the Royal College of Paediatrics and Child Health and the Royal College of Ophthalmologists in March 2022,and formally published in Early Human Development in March 2023.The guidelines provide evidence-based recommendations for the screening and treatment of ROP.The most significant change in the 2022 updated version compared to the previous guidelines is the lowering of the gestational age screening criterion to below 31 weeks.The treatment section covers treatment indications,timing,methods,and follow-up visits of ROP.This article interprets the guidelines and compares them with ROP guidelines/consensus in China,providing a reference for domestic peers.

Objective To investigate the efficacy and safety of stereotactic body radiotherapy(SBRT)combined with camrelizumab and apatinib in treatment of advanced hepatocellular carcinoma(HCC).Methods The clinical data were retrospectively analyzed of 85 patients with advanced HCC treated in the Fifth Affiliated Hospital of Zhengzhou University and People's Hospital of Zhengzhou from January 2019 to September 2021.They were divided into observation group(n=31,SBRT combined with camrelizumab and apatinib)and control group(n=54,treated with camrelizumab and apatinib)according to whether they received SBRT.The propensity score matching(PSM)was used to balance the influence of confounding factors.The objective remission rate(ORR)and disease control rate(DCR)were compared between the two groups.The 6-month overall survival rate,1-year overall survival rate and progression-free survival(PFS)were compared between the two groups by Kaplan-Meier method.The safety of the two groups was evaluated by Common Terminology Criteria for Adverse Events(CTCAE)version 5.0.Results Before PSM,there were significant differences in age(P=0.043),number of extrahepatic metastasis(P=0.028),and previous surgical treatment(P=0.038)between the two groups.After PSM,there was no significant difference in baseline characteristics between the two groups(P>0.05).After PSM,27 cases were included in each groups,and three months after treatment,the ORR in observation group and control group were 66.7%and 29.6%,respectively,showed difference with statistically significant(P=0.006);and the DCR in the both groups were 96.3%and 85.2%respectively,showed no statistically significant difference(P=0.175).There were statistical differences in 6-month overall survival rate(96.3%vs.80.9%,P=0.001),1-year overall survival rate(75.0%vs.61.4%,P=0.034)and median PFS(8 months vs.5 months,P=0.003)between the observation group and control group.Multi-factor Cox regression analysis showed that baseline alpha-fetoprotein(AFP)≥400 ng/ml was an independent risk factor for affecting the survival of patients with advanced HCC(HR>1,P<0.05),while the triple therapy and previous targeted drugs therapy were the protective factors for the survival of patients with advanced HCC(HR<1,P<0.05).In the observation group,4 patients had grade 3 adverse reactions,and the common adverse reactions were dyspepsia(14.8%).One case of grade 3 adverse reactions occurred in control group,and there was no statistically significant difference in the incidence of adverse reactions between the two groups(P=0.639).Conclusion SBRT combined with camrelizumab and apatinib is a safe and effective treatment for advanced HCC with significant clinical effect and controllable adverse reactions.

Objective: To analyze the efficacy and prognostic factors of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for treating T lymphoblastic leukemia/lymphoma (T-ALL/LBL) . Methods: This study retrospectively evaluated 119 adolescent and adult patients with T-ALL/LBL from January 2006 to January 2020 at Peking University Third Hospital and Institute of Hematology and Blood Diseases Hospital, Chinese Academy of Medical Sciences. Patients were divided into chemotherapy-only, chemotherapy followed by allo-HSCT, and chemotherapy followed by autologous hematopoietic stem cell transplantation (auto-HSCT) groups according to the consolidation regimen, and the 5-year overall survival (OS) and progression-free survival (PFS) rates of each group were compared. Results: Among 113 patients with effective follow-up, 96 (84.9%) patients achieved overall response (ORR), with 79 (69.9%) having complete response (CR) and 17 (15.0%) having partial response (PR), until July 2022. The analysis of the 96 ORR population revealed that patients without transplantation demonstrated poorer outcomes compared with the allo-HSCT group (5-year OS: 11.4% vs 55.6%, P=0.001; 5-year PFS: 8.9% vs 54.2%, P<0.001). No difference was found in 5-year OS and 5-year PFS between the allo-HSCT and auto-HSCT groups (P=0.271, P=0.197). The same results were achieved in the CR population. Allo-HSCT got better 5-year OS (37.5% vs 0) for the 17 PR cases (P=0.064). Different donor sources did not affect 5-year OS, with sibling of 61.1% vs hap-haploidentical of 63.6% vs unrelated donor of 50.0% (P>0.05). No significant difference was found in the treatment response in the early T-cell precursor acute lymphoblastic leukemia/lymphoma (ETP) and non-ETP populations. The ETP group demonstrated lower 5-year OS compared with the non-ETP group in the chemotherapy alone group (0 vs 12.6%, P=0.045), whereas no significant difference was found between the ETP and non-ETP groups in the allo-HSCT group (75.0% vs 62.9%, P=0.852). Multivariate analysis revealed that high serum lactate dehydrogenase level, without transplantation, and no CR after chemotherapy induction were independently associated with inferior outcomes (P<0.05) . Conclusion: Allo-HSCT could be an effective consolidation therapy for adult and adolescent patients with T-ALL/LBL. Different donor sources did not affect survival. Allo-HSCT may overcome the adverse influence of ETP-ALL/LBL on OS.

Abstract: Objective　To investigate the drug demand and related influencing factors of AIDS non-occupational post-exposure prophylaxis (nPEP) among men who have sex with men (MSM) in Wuhan, and to provide a scientific basis for the development of subsequent intervention policies for MSM. Methods　With the assistance of social organizations in Wuhan, MSM was recruited by the snowball method to carry out an online questionnaire survey to collect information on demographics, AIDS-related knowledge, high-risk behaviors, and the need for nPEP medication. The χ2 test and unconditional Logistic regression were used to analyze the related factors of the demand for nPEP medication. Results　A total of 308 valid subjects were included in this study, with predominantly 18-29 years old (78.57%, 242/308). The self-reported sexual orientation was mainly homosexuality (82.47%, 254/308), and the awareness rate of AIDS knowledge was high (89.29%, 275/308). Among the survey respondents, 35.06% (108/308) did not know the situation of HIV infection among MSM population in Wuhan; 55.19% (170/308) had two or more same-sex sexual partners in the last six months; 90.91% (280/308) had heard of nPEP before participating in this survey. After passing nPEP and informing the protective effect of nPEP, 59.42% (183/308) of them needed nPEP. After HIV exposure, 73.38% (226/308) were willing to spend money to buy nPEP drugs, and 88.64% (273/308) were willing to take nPEP drugs because of the known side effects. Logistic regression analysis showed that in the last six months, the needs for taking nPEP medication in those who had 2 or more same-sex sexual partners (OR=2.121, 95%CI: 1.329-3.386) and who had received peer education (OR=1.740, 95%CI: 1.088-2.781) were higher than those of those who had a same-sex sexual partner in the last six months and who had not received peer education. Conclusions　The MSM population in Wuhan has a great demand for nPEP drugs, and peer education is an important way to carry out nPEP publicity and promotion. At the same time, we should continue to strengthen warning publicity and education and behavioral intervention to reduce MSM risky sexual behaviors and reduce new HIV infections.
