Everyone has a donor: contribution of the Chinese experience to global practice of haploidentical hematopoieticstem cell transplantation

Meng Lv, Yingjun Chang, Xiaojun Huang

《医学前沿（英文）》 2019年 第13卷 第1期   页码 45-56 doi: 10.1007/s11684-017-0595-7

摘要： Human leukocyte antigen (HLA)-matched donors for hematopoietic stem cell transplantation (HSCT) have long been scarce in China. Haploidentical (haplo) donors are available for the vast majority of patients, but toxicity has limited this approach. Three new approaches for haplo-HSCT originated from Italy, China, and USA in 1990 and have been developed to world-renowned system up to now. The Chinese approach have been greatly improved by implementing new individualized conditioning regimens, donor selection based on non-HLA systems, risk-directed strategies for graft-versus-host disease and relapse, and infection management. Haplo-HSCT has exhibited similar efficacy to HLA-matched HSCT and has gradually become the predominant donor source and the first alternative donor choice for allo-HSCT in China. Registry-based analyses and multicenter studies adhering to international standards facilitated the transformation of the unique Chinese experience into an inspiration for the refinement of global practice. This review will focus on how the new era in which “everyone has a donor” will become a reality in China.

leukemia/myelodysplastic syndrome with unsatisfactory response to minimal residual disease-directed donorlymphocyte infusion after allogeneic hematopoietic stem cell transplantation

Xiaodong Mo, Xiaohui Zhang, Lanping Xu, Yu Wang, Chenhua Yan, Huan Chen, Yuhong Chen, Wei Han, Fengrong Wang, Jingzhi Wang, Kaiyan Liu, Xiaojun Huang

《医学前沿（英文）》 2019年 第13卷 第2期   页码 238-249 doi: 10.1007/s11684-017-0599-3

摘要： The efficacy of salvage interferon-α (IFN-α) treatment was investigated in patients with unsatisfactory response to minimal residual disease (MRD)-directed donor lymphocyte infusion (DLI) ( =24). Patients who did not become MRD-negative at 1 month after DLI were those with unsatisfactory response and were eligible to receive salvage IFN-α treatment within 3 months of DLI. Recombinant human IFN-α-2b injections were subcutaneously administered 2–3 times a week for 6 months. Nine (37.5%), 6 (25.0%), and 3 (12.5%) patients became MRD-negative at 1, 2, and>2 months after the salvage IFN-α treatment, respectively. Two-year cumulative incidences of relapse and non-relapse mortality were 35.9% and 8.3%, respectively. Two-year probabilities of event-free survival, disease-free survival, and overall survival were 51.6%, 54.3%, and 68.0%, respectively. Outcomes of patients subjected to salvage IFN-α treatment after DLI were significantly better than those with persistent MRD without IFN-α treatment. Moreover, clinical outcomes were comparable between the salvage DLI and IFN-α treatment groups. Thus, salvage IFN-α treatment may help improve the outcome of patients with unsatisfactory responses to MRD-directed DLI and could be a potential salvage treatment for these patients after allogeneic hematopoietic stem cell transplantation.

used as a salvage option for patients with relapsed acute leukemia post-chemotherapy plus modified donor

《医学前沿（英文）》 2021年 第15卷 第5期   页码 728-739 doi: 10.1007/s11684-021-0833-x

摘要： Relapse is the main problem after allogeneic hematopoietic stem cell transplantation (allo-HSCT). The outcome of a second allo-HSCT (HSCT2) for relapse post-HSCT has shown promising results in some previous studies. However, little is known about the efficacy of HSCT2 in patients with relapsed/refractory acute leukemia (AL) post-chemotherapy plus modified donor lymphocyte infusion (post-Chemo+m-DLI) after the first allo-HSCT (HSCT1). Therefore, we retrospectively analyzed the efficacy of HSCT2 in 28 patients with relapsed/refractory AL post-Chemo+m-DLI in our center. With a median follow-up of 918 (457–1732) days, 26 patients (92.9%) achieved complete remission, and 2 patients exhibited persistent disease. The probabilities of overall survival (OS) and disease-free survival (DFS) 1 year after HSCT2 were 25.0% and 21.4%, respectively. The cumulative incidences of nonrelapse mortality on day 100 and at 1 year post-HSCT2 were 7.1%±4.9% and 25.0%±8.4%. The cumulative incidences of relapse were 50.0%±9.8% and 53.5%±9.9% at 1 and 2 years post-HSCT2, respectively. Risk stratification prior to HSCT1 and percentage of blasts before HSCT2 were independent risk factors for OS post-HSCT2, and relapse within 6 months post-HSCT1 was an independent risk factor for DFS and relapse post-HSCT2. Our findings suggest that HSCT2 could be a salvage option for patients with relapsed AL post-Chemo+m-DLI.

《医学前沿（英文）》 2013年 第7卷 第3期   页码 306-315 doi: 10.1007/s11684-013-0279-x

摘要：

Allogeneic hematopoietic stem cell transplantation (HSCT) is one of the most effective options for hematological malignancies, and human leukocyte antigen-partially matched related donors (PMRDs) are a valuable option for HSCT. Several protocols (with or without ex vivo T-cell depletion (TCD)) have been established worldwide. TCD including CD34+positive selection and CD3/CD19 depletion has successfully overcome the human leukocyte antigen disparity. However, TCD is associated with prolonged immune deficiencies, increased risks of infectious complications, and high transplantation-related mortality. PMRD HSCT without ex vivo TCD is well developed, and numerous patients have benefitted from it. Here, we review the literature on PMRD HSCT.

patients receiving haploidentical allografts and those receiving human leukocyte antigen-matched sibling donor

《医学前沿（英文）》 2018年 第12卷 第2期   页码 153-163 doi: 10.1007/s11684-017-0548-1

摘要：

To establish optimal reference values for recovered immune cell subsets, we prospectively investigated post-transplant immune reconstitution (IR) in 144 patients who received allogeneic stem cell transplantation (allo-SCT) and without showing any of the following events: poor graft function, grades II?IV acute graft-versus-host disease (GVHD), serious chronic GVHD, serious bacterial infection, invasive fungal infection, or relapse or death in the first year after transplantation. IR was rapid in monocytes, intermediate in lymphocytes, CD3+ T cells, CD8+ T cells, and CD19+ B cells, and very slow in CD4+ T cells in the entire patient cohort. Immune recovery was generally faster under HLA-matched sibling donor transplantation than under haploidentical transplantation. Results suggest that patients with an IR comparable to the reference values display superior survival, and the levels of recovery in immune cells need not reach those in healthy donor in the first year after transplantation. We suggest that data from this recipient cohort should be used as reference values for post-transplant immune cell counts in patients receiving HSCT.

The influence of brain death on donor liver and the potential mechanisms of protective intervention

null

《医学前沿（英文）》 2011年 第5卷 第1期   页码 8-14 doi: 10.1007/s11684-011-0109-y

摘要：

Brain-dead donors have become one of the main sources of organs for transplantation in Western countries. The quality of donor organs is closely related to the outcome of the transplantation. Experimental studies have confirmed the inferior graft survival of livers from brain-dead donors compared with those from living donors. Studies conducted in the past 10 years have shown that brain death is associated with effects on the decreased donor organ quality. However, whether the decrease in the viability of donor organs is caused by brain death or by the events before and after brain death remains uncertain. The purpose of this review is to introduce the advances and controversies regarding the influence of brain death on the viability of donor livers and to summarize the mechanisms of the different protective interventions for donor livers.

Regulation of radicals by hydrogen-donor solvent in direct coal liquefaction

《化学科学与工程前沿（英文）》 2022年 第16卷 第12期   页码 1689-1699 doi: 10.1007/s11705-022-2186-7

摘要： Radicals are important intermediates in direct coal liquefaction. Certain radicals can cause the cleavage of chemical bonds. At high temperatures, radical fragments can be produced by the splitting of large organic molecules, which can break strong chemical bonds through the induction pyrolysis of radicals. The reaction between the formation and annihilation of coal radical fragments and the effect of hydrogen-donor solvents on the radical fragments are discussed in lignite hydrogenolysis. Using the hydroxyl and ether bonds as indicators, the effects of different radicals on the cleavage of chemical bond were investigated employing density functional theory calculations and lignite hydrogenolysis experiments. Results showed that the adjustment of the coal radical fragments could be made by the addition of hydrogen-donor solvents. Results showed that the transition from coal radical fragment to H radical leads to the variation of product distribution. The synergistic mechanism of hydrogen supply and hydrogenolysis of hydrogen-donor solvent was proposed.

摘要：

Using a data set from our laboratory, we assessed the effects of several factors on pig cloning efficiency. The results demonstrated that cells at high confluence (>90%) used as donor cell resulted in higher pregnancy rate, delivery rate and overall cloning efficiency (number of live offspring born per reconstructed embryo transferred to recipients) compared with the cells at 60% to 79% confluence and 80% to 89% confluence. Cells with four, five and six passages compromised the pregnancy and delivery rates compared with first passage cells. The number of blastocysts transferred by somatic cell nuclear transfer (SCNT) did not significantly affect the cloning efficiency, but transfer of blastocyst derived from culture 5 d after SCNT achieved a significantly higher pregnancy rate compared with one to two cell SCNT embryos from overnight culture. The highest pregnancy rate, delivery rate and the largest litter size were obtained when Bama Miniature pig fibroblasts were used as donor cells and Landrace/Yorkshire hybrid gilts were used as recipients. Recipients treated with chemicals for estrus synchronization had higher pregnancy rates compared with untreated recipients. Our data might be helpful for improving SCNT efficiency in pigs.

Enhanced photoelectrochemical water splitting with a donor-acceptor polyimide

《能源前沿（英文）》 doi: 10.1007/s11708-023-0910-8

摘要： Polyimide (PI) has emerged as a promising organic photocatalyst owing to its distinct advantages of high visible-light response, facile synthesis, molecularly tunable donor-acceptor structure, and excellent physicochemical stability. However, the synthesis of high-quality PI photoelectrode remains a challenge, and photoelectrochemical (PEC) water splitting for PI has been less studied. Herein, the synthesis of uniform PI photoelectrode films via a simple spin-coating method was reported, and their PEC properties were investigated using melamine as donor and various anhydrides as acceptors. The influence of the conjugate size of aromatic unit (phenyl, biphenyl, naphthalene, perylene) of electron acceptor on PEC performance were studied, where naphthalene-based PI photoelectrode exhibited the highest photocurrent response. This is resulted from the unification of wide-range light absorption, efficient charge separation and transport, and strong photooxidation capacity. This paper expands the material library of polymer films for PEC applications and contributes to the rational design of efficient polymer photoelectrodes.

《医学前沿（英文）》 2019年 第13卷 第3期   页码 354-364 doi: 10.1007/s11684-018-0665-5

摘要： The efficacy of minimal residual disease (MRD)-directed immunotherapy, including interferon- (IFN- ) treatment and chemotherapy plus granulocyte colony-stimulating factor-primed donor leukocyte infusion (chemo-DLI), was investigated in patients with high-risk myelodysplastic syndrome (MDS) who were MRD-positive after allogeneic hematopoietic stem cell transplantation (allo-HSCT). High-risk MDS patients who received non-T-cell-depleted allo-HSCT at the Peking University Institute of Hematology and were MRD-positive after allo-HSCT were studied ( =47). The MRD-positive status was considered if leukemia-associated aberrant immune phenotypes or Wilms’ tumor gene 1 expression is present in a single bone marrow sample. The cumulative incidence of the relapse and non-relapse mortality 2 years after immunotherapy were 14.5% and 21.4% ( =0.377) and 9.1% and 0.0% ( =0.985) for patients in the IFN- and chemo-DLI groups, respectively. The probability of disease-free and overall survival 2 years after immunotherapy were 76.4% and 78.6% ( =0.891) and 84.3% and 84.6% ( =0.972) for patients in the IFN- and chemo-DLI groups, respectively. Persistent MRD after immunotherapy was associated with poor survival. Thus, the MRD-directed immunotherapy was effective for patients with high-risk MDS who were MRD-positive after allo-HSCT, and the efficacy was comparable between chemo-DLI and IFN- treatment.

Partial liver transplantation

《医学前沿（英文）》 2011年 第5卷 第1期   页码 1-7 doi: 10.1007/s11684-010-0105-7

摘要：

Partial liver transplantation, including reduced-size liver transplantation, split liver transplantation, and living donor liver transplantation, has been developed with several innovative techniques because of donor shortage. Reduced-size liver transplantation is based on Couinaud’s anatomical classification, benefiting children and small adult recipients but failing to relieve the overall donor shortage. Split liver transplantation provides chances to two or even more recipients when only one liver graft is available. The splitting technique must follow stricter anatomical and physiological criteria either ex situ or in situto ensure long-term quality. The first and most important issue involving living donor liver transplantation is donor safety. Before surgery, a series of donor evaluations—including anatomical, liver volume, and liver function evaluations—is indispensable, followed by ethnic agreement. At different recipient conditions, auxiliary liver transplantation and auxiliary partial orthotopic liver transplantation, which employ piggyback techniques, are good alternatives. Partial liver transplantation enriches the practice and knowledge of the transplant society.

摘要：

移植是终末期肝病最有效的治疗方法，但由于供体器官的短缺而受到限制。扩大标准供体（ECD）供肝在临床实践中越来越多地用于缓解这一挑战。然而，这些移植物耐受缺血的能力下降，危及冷保存期间器官的活力。机器灌注（MP）旨在改善器官保存并减少移植后并发症。然而，越来越明显的是，单独使用MP无法达到ECD供肝的最佳保存。因此，人们逐渐开始重视改良的 MP 策略，包括使用不同的灌注剂、改良的灌注方式并结合不同的治疗干预策略。本文中，我们提出了“机械灌注+”的新理念，代表这些旨在提升器官功能并可能实现ECD供肝体外再生的机械灌注新策略。为此，我们总结了现有和改良的MP策略，并阐述其在临床场景中修复不同ECD供肝的优势。

《医学前沿（英文）》 2008年 第2卷 第2期   页码 130-133 doi: 10.1007/s11684-008-0024-z

摘要： The aim of this paper is to summarize our experience of using right lobe liver grafts to reduce biliary complications in adult-to-adult (A-A) living donor liver transplantation (LDLT). From January 2002 to October 2007, 124 adult patients underwent living donor liver transplantation using right lobe grafts at the West China Hospital, Sichuan University Medical School, China. There was no death in all donors. Biliary reconstruction for 178 hepatic duct orifices from 124 donor grafts was performed which included 106 reconstructions of duct-to-duct anastomoses and 72 cholangiojejunostomy. Nine recipients had biliary complications including six bile leakages (four from the anastomotic site and two from the cut surface of the liver graft) and three biliary strictures. With the improved techniques for biliary reconstruction, we have achieved good results in 124 recipients of A-A LDLT. We ascribe our success to the introduction of microsurgical techniques and the use of fixed operators which help in decreasing the biliary complications of LDLT.
