2Ionic liquid based dispersive liquid-liquid microextraction of aromatic amines in water samples显示文摘In this work,a new microextraction method termed ionic liquid based dispersive liquid-liquid microextraction(IL-DLLME) was demonstrated for the extraction of 2-methylaniline,4-chloroaniline,1-naphthylamine and 4-aminobiphenyl in aqueous matrices.After extraction the ionic liquid(IL)phase was injected directly into the high performance liquid chromatography(HPLC) system for determination.Some parameters that might affect the extraction efficiency were optimized.Under the optimum conditions,good linear relationship,sensitivity and reproducibility were obtained.The limits of detection(LOD,S/N=3)for the four analytes were in the range of 0.45-2.6μg L^(-1).The relative standard deviations(R.S.D.,n=6)were in the range of 6.2-9.8%. This method was applied for the analysis of the real water samples.The recoveries ranged from 93.4 to 106.4%.The main advantages of the method are high speed,high recovery,good repeatability and volatile organic solvent-free.Yun Chang Fan Zheng Liang Hu Mei Lan Chen Chao Shen Tu Yan Zhu 2008Chinese Chemical Letters2008,19,8:13
3First mass measurement of short-lived nuclides at HIRFL-CSR显示文摘Recent commissioning of the HIRFL-CSR has demonstrated its ability to perform direct mass measurement for short-lived nuclides. Projectile fragments produced by the 78Kr ions at 481.88 MeV/u were separated with the new radioactive beam line in Lanzhou (RIBLL2), and injected into and stored in the experimental storage ring (CSRe). By operating the CSRe as an isochronous mass spectrometry, a typical mass resolution around 2.0×10?5 has been achieved. The masses for 63Ge, 65As and 67Se were measured for the first time. The measured masses are compared with theoretical predictions and the location of the proton drip-line for As isotopes is discussed. The implication of the 65As mass in the astrophysical rapid proton capture process has also been addressed.XU HuShan TU XiaoLin YUAN YouJin XIA JiaWen ZANG YongDong WANG Meng MAO RuiShi HU ZhengGuo MEI Bo SHUAI Peng ZHU ZhiChao TANG ShuWen GENG Peng LIU Yong ZHAO TieCheng ZHANG XueYing YANG JianCheng MAO LiJun ZHANG YuHu ZHOU XiaoHong HUANG WenXue XIAO GuoQing ZHAO HongWei ZHAN WenLong 2009Chinese Science Bulletin2009,54,24:11
4Speciation and fractionation of heavy metals in soil experimentally contaminated with Pb, Cd, Cu and Zn together and effects on soil negative surface charge显示文摘Speciation and fractionation of heavy metals in soil subsamples experimentally loaded with Pb, Cd, Cu and Zn in orthogonal design was investigated by sequential extraction, and operationally defined as water soluble and exchangeable(SE), weakly specific adsorbed(WSA), Fe and Mn oxides bound(OX) and organic bound(ORG). The results showed that fractions of heavy metals in the soil subsamples depended on their speciation. About 90% of Cd and 75% of Zn existed in soil subsamples in the SE fraction. Lead and Cu existed in soil subsamples as SE, WSA and OX fractions simultaneously, although SE was still the major fraction. Organic bound heavy metals were not clearly apparent in all the soil subsamples. The concentration of some heavy metal fractions in soil subsamples showed the good correlation with ionic impulsion of soil, especially for the SE fraction. Continuous saturation of soil subsamples with 0.20 mol/L NH 4Cl, which is the first step for determination of the negative surface charge of soil by the ion retention method, resulted in desorption of certain heavy metals from the soil. It was found that the percentage desorption of heavy metals from soil subsamples depended greatly on pH, the composition and original heavy metal content of the soil subsamples. However, most of the heavy metals in the soil subsamples were still be retained after multiple saturation. Compared with the parent soil, the negative surface charge of soil subsamples loaded with heavy metals did not show difference significantly from that of the parent one by statistical analysis. Heavy metals existed in the soil subsamples mainly as exchangeable and precipitated simultaneously.ZHOU Dong mei, HAO Xiu zhen, TU Cong, CHEN Huai man, SI You bin (Institute of Soil Science, Chinese Academy of Sciences, Nanjing 210008, China. ) 2002Journal of Environmental Sciences2002,14,4:10
5Chemoprophylaxis, diagnosis, treatments, and discharge management of COVID-19: An evidence-based clinical practice guideline(updated version)显示文摘The novel severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)is the cause of a rapidly spreading illness,coronavirus disease 2019(COVID-19),affecting more than seventeen million people around the world.Diagnosis and treatment guidelines for clinicians caring for patients are needed.In the early stage,we have issued'A rapid advice guideline for the diagnosis and treatment of 2019 novel coronavirus(2019-nCoV)infected pneumonia(standard version)';now there are many direct evidences emerged and may change some of previous recommendations and it is ripe for develop an evidence-based guideline.We formed a working group of clinical experts and methodologists.The steering group members proposed 29 questions that are relevant to the management of COVID-19 covering the following areas:chemoprophylaxis,diagnosis,treatments,and discharge management.We searched the literature for direct evidence on the management of COVID-19,and assessed its certainty generated recommendations using the Grading of Recommendations,Assessment,Development and Evaluation(GRADE)approach.Recommendations were either strong or weak,or in the form of ungraded consensus-based statement.Finally,we issued 34 statements.Among them,6 were strong recommendations for,14 were weak recommendations for,3 were weak recommendations against and 11 were ungraded consensus-based statement.They covered topics of chemoprophylaxis(including agents and Traditional Chinese Medicine(TCM)agents),diagnosis(including clinical manifestations,reverse transcription-polymerase chain reaction(RT-PCR),respiratory tract specimens,IgM and IgG antibody tests,chest computed tomography,chest X-ray,and CT features of asymptomatic infections),treatments(including lopinavirritonavir,umifenovir,favipiravir,interferon,remdesivir,combination of antiviral drugs,hydroxychloroquine/chloroquine,interleukin-6 inhibitors,interleukin-1 inhibitors,glucocorticoid,qingfei paidu decoction,lianhua qingwen granules/capsules,convalescent plasma,lung transplantation,invasive or noninvasive ventilation,and extracorporeal membrane oxygenation(ECMO)),and discharge management(including discharge criteria and management plan in patients whose RT-PCR retesting shows SARS-CoV-2 positive after discharge).We also created two figures of these recommendations for the implementation purpose.We hope these recommendations can help support healthcare workers caring for COVID-19 patients.Ying-Hui Jin Qing-Yuan Zhan Zhi-Yong Peng Xue-Qun Ren Xun-Tao Yin Lin Cai Yu-Feng Yuan Ji-Rong Yue Xiao-Chun Zhang Qi-Wen Yang Jianguang Ji Jian Xia Yi-Rong Li Fu-Xiang Zhou Ya-Dong Gao Zhui Yu Feng Xu Ming-Li Tu Li-Ming Tan Min Yang Fang Chen Xiao-Ju Zhang Mei Zeng Yu Zhu Xin-Can Liu Jian Yang Dong-Chi Zhao Yu-Feng Ding Ning Hou Fu-Bing Wang Hao Chen Yong-Gang Zhang Wei Li Wen Chen Yue-Xian Shi Xiu-Zhi Yang Xue-Jun Wang Yan-Jun Zhong Ming-Juan Zhao Bing-Hui Li Lin-Lu Ma Hao Zi Na Wang Yun-Yun Wang Shao-Fu Yu Lu-Yao Li Qiao Huang Hong Weng Xiang-Ying Ren Li-Sha Luo Man-Ru Fan Di Huang Hong-Yang Xue Lin-Xin Yu Jin-Ping Gao Tong Deng Xian-Tao Zeng Hong-Jun Li Zhen-Shun Cheng Xiao-Mei Yao Xing-Huan Wang 2020Military Medical Research2020,7,3:6
6Comparison of Clinical Efficacy of Three Methods for Cervical Ripening followed by Surgical Evacuation in Early Missed Abortion显示文摘Objective To compare clinical efficacy of three cervical preparations for surgical evacuation in first trimester missed abortion.Methods Two hundred and ten women with early missed abortion were equally randomized into three groups.Three cervical preparations,Dilapan-dilator method(group A,n=70),mifepristone method(group B,n=70),and misoprostol method(group C,n=70),were used 24 h before curettage for terminating missed abortion,respectively.Clinical outcomes and complications for these three methods were compared.Results No differences were found in rates of successful treatment among the three groups(P>0.05).The incidence of fitting number 8 Hegar dilator was slightly high in group A,but it was not different compared with that in group B or group C(P>0.05).Bleeding in previous 24 h in group C was significantly greater than that in group A or group B(P<0.01).The cases of blood loss(>50 ml) during evacuation in group B were more than those in group A(P>0.05).Women in group B had less abdominal pain than those in group A or group C(P<0.01).Side effects in group C were more than those in group A on nausea(P<0.01),vomiting(P<0.05),and diarrhea(P<0.01).Group B had the highest acceptability among the three groups(P<0.05).Conclusion Three methods have the similar clinical efficacies in cervical ripening for surgical treatment of early missed abortion.Based on individual characteristics,different approach would be chosen to avoid some adverse events and improve the clinical application of Dilapan-dilator.Yu-xia WANG Mi-jiao HUANG Ting HE Rong ZENG Wei-jie ZHU Mei TU 2012Journal of Reproduction and Contraception2012,23,2:6
7Platinum-group elements for the mantle peridotites in the Dazhuka ophiolite,Tibet,China显示文摘The total PGE amounts of mantle peridotites in the Dazhuka ophiolite, Tibet, are 28.37-50.67 ng/g, slightly higher than those of mantle peridotites in the primitive mantle, and typical ophiolites in the world, and the Alps-type mantle peridotites. The PGE distribution patterns in the Dazhuka mantle peridotites are also different from those of the mantle peridotites of partial melting relict origin. The Dazhuka mantle peridotites have relatively high total PGE amounts and are enriched in Pt, Pd, and Ru. Their PGE distribution patterns belong to the positively inclined-or swallow-type patterns. The PGE distribution patterns in the mantle peridotites of partial melting relict origin belong to the negative-slope patterns or flat patterns. This reflects the unique features of the upper mantle in this region. Relative enrichment in Pt and Pd, as well as in the incompatible elements Cu, Au, Cs, Rb, Ba, Th, U and LREE, indicates that the partial melting-derived relict mantle peridotites in the DazhukaYU Henqxiang XIA Bin MEI Houjun GUO Linzhi QI Liang TU Xianglin 2001Chinese Science Bulletin2001,46,3:5
8Inhibition of cyclooxygenase-2 activity in subchondral bone modifies a subtype of osteoarthritis显示文摘Osteoarthritis(OA) causes the destruction of joints. Its pathogenesis is still under investigation, and there is no effective diseasemodifying therapy. Here, we report that elevated cyclooxygenase-2(COX-2) expression in the osteocytes of subchondral bone causes both spontaneous OA and rheumatoid arthritis(RA). The knockout of COX-2 in osteocytes or treatment with a COX-2 inhibitor effectively rescues the structure of subchondral bone and attenuates cartilage degeneration in spontaneous OA(STR/Ort)mice and tumor necrosis factor-α transgenic RA mice. Thus, elevated COX-2 expression in subchondral bone induces both OAassociated and RA-associated joint cartilage degeneration. The inhibition of COX-2 expression can potentially modify joint destruction in patients with arthritis.Manli Tu Mi Yang Nanxi Yu Gehua Zhen Mei Wan Wenlong Liu Baochao Ji Hairong Ma Qiaoyue Guo Peijian Tong Li Cao Xianghang Luo Xu Cao 2019Bone Research2019,7,3:5
9Resveratrol promotes the survival and neuronal differentiation of hypoxia-conditioned neuronal progenitor cells in rats with cerebral ischemia显示文摘Hypoxia conditioning could increase the survival of transplanted neuronal progenitor cells(NPCs)in rats with cerebral ischemia but could also hinder neuronal differentiation partly by suppressing mitochondrial metabolism.In this work,the mitochondrial metabolism of hypoxia-conditioned NPCs(hcNPCs)was upregulated via the additional administration of resveratrol,an herbal compound,to resolve the limitation of hypoxia conditioning on neuronal differentiation.Resveratrol was first applied during the in vitro neuronal differentiation of hcNPCs and concurrently promoted the differentiation,synaptogenesis,and functional development of neurons derived from hcNPCs and restored the mitochondrial metabolism.Furthermore,this herbal compound was used as an adjuvant during hcNPC transplantation in a photothrombotic stroke rat model.Resveratrol promoted neuronal differentiation and increased the long-term survival of transplanted hcNPCs.18-fluorine fluorodeoxyglucose positron emission tomography and rotarod test showed that resveratrol and hcNPC transplantation synergistically improved the neurological and metabolic recovery of stroke rats.In conclusion,resveratrol promoted the neuronal differentiation and therapeutic efficiency of hcNPCs in stroke rats via restoring mitochondrial metabolism.This work suggested a novel approach to promote the clinical translation of NPC transplantation therapy.Yao Yao Rui Zhou Rui Bai Jing Wang Mengjiao Tu Jingjing Shi Xiao He Jinyun Zhou Liu Feng Yuanxue Gao Fahuan Song Feng Lan Xingguo Liu Mei Tian Hong Zhang 2021Frontiers of Medicine2021,15,3:3
10Development of a polarized ~3He neutron spin filter based on spin exchange optical pumping at China Mianyang Research Reactor显示文摘Spin-polarized^3He gas is widely used in many research areas.It is used to search for new spin-dependent interactions beyond the standard model[1,2].It works as a target for electron scattering when studying the spin structure of neurons in high-energy and nuclear physics[3].Also,it works as a neutron spin filter(NSF)for polarizing/analyzing neutron polarizations in scattering experiments[4-7].One of the advantages of neutron scattering is that the neutron has a magnetic moment;thus,it can detect a magnetic structure with high sensitivity.If the neutrons are polarized,this advantage can be greatly improved because polarized neutron scattering techniques can easily differentiate between magnetic and nuclear scattering.By comparison,it is not very easy for other techniques such as X-ray scattering to separate magnetic interactions from electrical ones in magnetic samples because the latter is usually much stronger than the former.Furthermore,by encoding energy change and scattering angle information into precessions of the neutron polarization,the energy and angle resolutions for scattering can be significantly increased using the so-called spin echo techniques.Song Yan Mo-Fan Zhang Wen-Chuan Guo Wen-Zhao Wang Jian Gong Tian-Jiao Liang Ben-Qiong Liu Mei Peng Shu-Ming Peng GuanAi Sun Xiao-Qing Tu Hai-Yang Yan Jian-Hua Zhang Hao Zheng 2019Science China(Physics,Mechanics & Astronomy)2019,62,10:3
112022 Chinese expert consensus and guidelines on clinical management of toxicity in anti-CD19 chimeric antigen receptor T-cell therapy for B-cell non-Hodgkin lymphoma显示文摘Adoptive cellular immunotherapy with chimeric antigen receptor(CAR)T cells has emerged as a novel modality for treating relapsed and/or refractory B-cell non-Hodgkin lymphoma(B-NHL).With increasing approval of CAR T-cell products and advances in CAR T cell therapy,CAR T cells are expected to be used in a growing number of cases.However,CAR T-cell-associated toxicities can be severe or even fatal,thus compromising the survival benefit from this therapy.Standardizing and studying the clinical management of these toxicities are imperative.In contrast to other hematological malignancies,such as acute lymphoblastic leukemia and multiple myeloma,anti-CD19 CAR T-cell-associated toxicities in B-NHL have several distinctive features,most notably local cytokine-release syndrome(CRS).However,previously published guidelines have provided few specific recommendations for the grading and management of toxicities associated with CAR T-cell treatment for B-NHL.Consequently,we developed this consensus for the prevention,recognition,and management of these toxicities,on the basis of published literature regarding the management of anti-CD19 CAR T-cell-associated toxicities and the clinical experience of multiple Chinese institutions.This consensus refines a grading system and classification of CRS in B-NHL and corresponding measures for CRS management,and delineates comprehensive principles and exploratory recommendations for managing anti-CD19 CAR T-cell-associated toxicities in addition to CRS.Ping Li Yang Liu Yun Liang Jian Bo Sujun Gao Yongxian Hu Yu Hu He Huang Xiaojun Huang Hongmei Jing Xiaoyan Ke Jianyong Li Yuhua Li Qifa Liu Peihua Lu Heng Mei Ting Niu Yongping Song Yuqin Song Liping Su Sanfang Tu Jianxiang Wang Depei Wu Zhao Wang Kailin Xu Zhitao Ying Qingming Yang Yajing Zhang Fengxia Shi Bin Zhang Huilai Zhang Xi Zhang Mingfeng Zhao Weili Zhao Xiangyu Zhao Liang Huang Jun Zhu Wenbin Qian Weidong Han Aibin Liang 2023Cancer Biology & Medicine2023,20,2:3
12PEG-asparaginase in BFM-90 regimen improves outcomes in adults with newly diagnosed lymphoblastic lymphoma显示文摘Objective: Although L-asparaginase(L-ASP) is a standard treatment for lymphoblastic lymphoma(LBL),hypersensitivity reactions by some patients limit its application. Polyethylene glycol-conjugated asparaginase(PEGASP) has a lower immunogenicity and is a standard treatment in all pediatric acute lymphoblastic leukemia(ALL).In this study, we investigated the efficacy and toxicity of PEG-ASP instead of L-ASP as used in the BFM-90regimen(PEG-ASP-BFM-90) for adult LBL.Methods: Between June 2012 and July 2015, we treated 30 adult patients with newly diagnosed LBL, using PEGASP-BFM-90 in a prospective, multicenter and single-arm clinical study at 5 participating institutions in China.Results: All the 30 patients, including 19 males and 11 females with a median age of 30(range: 18–62) years,completed 128 times of the PEG-ASP, with the median of 4(range: 2–6) times. Patients did not receive radiotherapy at this time. The overall response rate was 86.7%(26/30), with 50.0%(15/30) complete response and36.7%(11/30) partial response. The 3-year overall survival was 46.0% [95% confidence interval(95% CI),28.2%–64.8%], and the 3-year progression-free survival was 43.0%(95% CI, 25.7%–62.0%). Major adverse events were myelosuppression, reduced fibrinogen, liver dysfunction and digestive tract toxicities. No allergic reaction and no treatment-related mortality or severe complications were recorded.Conclusions: Our clinical data and observed outcomes indicate that 1 dose of PEG-ASP can replace multiple doses of native L-ASP in BFM-90, with predominantly grade 3–4 neutropenia for adult LBL, and no therapyrelated deaths. The effect is similar to previous reports of PEG-ASP-containing regimens for adult ALL. Major advantages include less serious allergic reactions, 2–3 weeks of action duration, and convenience for patients and physicians.Wen Zheng Hanyun Ren Xiaoyan Ke Mei Xue Yongqing Zhang Yan Xie Ningjing Lin Meifeng Tu Weiping Liu Lingyan Ping Zhitao Ying Chen Zhang Lijuan Deng Xiaopei Wang Yuqin Song Jun Zhu 2017Chinese Journal of Cancer Research2017,29,1:2
13Crucial control measures to contain China's first Delta variant outbreak显示文摘The SARS-C oV-2 B.1.617.2(Delta) variant flared up in late May in Guangzhou,China.Transmission characteristics of Delta variant were analysed for 153 confirmed cases and two complete transmission chains with seven generations were fully presented.A rapid transmission occurred in five generations within10 days.The basic reproduction number(R_0) was 3.60(95% confidence interval:2.50-5.30).After redefining the concept of close contact,the proportion of confirmed cases discovered from close contacts increased from 43% to 100%.With the usage of a yellow health code,the potential exposed individuals were self-motivated to take a nucleic acid test and regained public access with a negative testing result.Facing the massive requirement of screening,novel facilities like makeshift inflatable laboratories were promptly set up as a vital supplement and 17 cases were found,with 1 pre-symptomatic.The dynamic adjustment of these three interventions resulted in the decline of Rt from 5.00 to 1.00 within 9 days.By breaking the transmission chain and eliminating the transmission source through extending the scope of the close-contact tracing,health-code usage and mass testing,the Guangzhou D elta epidemic was effectively contained.Lei Luo Zifeng Yang Jingyi Liang Yu Ma Hui Wang Chitin Hon Mei Jiang Zhengshi Lin Wenda Guan Zhitong Mai Yongming Li Kailin Mai Zhiqi Zeng Chuanmeizi Tu Jian Song Bin Liu Yong Liu Jianfeng He Huiyuan Li Bosheng Li Hang Dong Yutian Miao Shujun Fan Lirui Fan Xingyi Liang Ke Li Chun Chen Huihong Deng Zhicong Yang Nanshan Zhong 2022National Science Review2022,9,4:2
14Comparison of Preliminary Clinical Efficacy for Two Cervical Preparations for Early Second-trimester Pregnancy Termination at 12-17 Weeks Gestation显示文摘Objective To compare clinical efficacy for two cervical preparations for early secondtrimester pregnancy termination at 12-17 weeks gestation. Methods Seventy healthy women aged 18-41 years requesting legal termination of pregnancy at 12-17 weeks of gestation were equally randomized into two groups. Two cervical preparations, the Dilapan-STM combined with mifepristone and misoprostol (DMM) method, and the mifepristone combined with misoprostol (MM) method, were used to end early second-trimester pregnancy for group DMM and group MM, respectively. Clinical outcomes and complications for these two methods were compared. Results No differences were found on rates of successful abortion within 48 h and blood loss after abortion at 2 h between the two groups (P>0.05). DMM group had significant shorter induction-to-abortion interval and hospital stay compared with group MM (P<0.01). In both DMM and MM groups, side effects including nausea/vomiting, diarrhea, chills and rigors, and fever occurred, and incidences of these side effects were no difference (P>0.05). Conclusion DMM method would have similar clinical efficacies with MM method for early second-trimester pregnancy termination. Besides,DMM method has shorter induction-to-abortion interval and hospital stay, which benefits its clinical application.Yu-xia WANG Rong ZENG Mi-jiao HUANG Wei-jie ZHU Mei TU 2011Journal of Reproduction and Contraception2011,22,2:2
15Plasma reforming of toluene as a model tar compound from biomass gasification:effect of CO_(2) and steam显示文摘In this study, plasma reforming of toluene as a tar model compound from biomass gasification has been carried out using an AC gliding arc discharge reactor. The influence of steam and CO_(2) addition on the reforming of toluene has been evaluated. The results show that the highest toluene conversion (59.9%) was achieved when adding 3 vol% CO_(2) at a toluene concentra-tion of 16.1 g/Nm3 and a specific energy input of 0.25 kWh/m3. Further increasing CO_(2) concentration to 12 vol% decreased the conversion of toluene. The presence of steam in the plasma CO_(2) reforming of toluene creates oxidative OH radicals which contribute to the enhanced conversion of toluene and energy efficiency of the plasma reforming process through stepwise oxidation of toluene and reaction intermediates. Hydrogen and C_(2)H_(2) were identified as the major gas products in the plasma reforming of toluene without CO_(2) or steam, with a yield of 9.7% and 14.5%, respectively, while syngas was the primary products with a maximum yield of 58.3% (27.5% for H_(2) and 30.8% for CO) in the plasma reforming with the addition of 12 vol% CO_(2). The plausible reaction pathways and mechanism in the plasma reforming of toluene have been proposed through the combination of the analysis of gas and condensed products and spectroscopic diagnostics.Shiyun Liu Danhua Mei Yaolin Wang Yichen Ma Xin Tu 2019Waste Disposal and Sustainable Energy2019,1,2:2

18Quantitative proteomics revealed extensive microenvironmental changes after stem cell transplantation in ischemic stroke显示文摘The local microenvironment is essential to stem cell-based therapy for ischemic stroke,and spatiotemporal changes of the microenvironment in the pathological process provide vital clues for understanding the therapeutic mechanisms.However,relevant studies on microenvironmental changes were mainly confined in the acute phase of stroke,and long-term changes remain unclear.This study aimed to investigate the microenvironmental changes in the subacute and chronic phases of ischemic stroke after stem cell transplantation.Herein,induced pluripotent stem cells(iPSCs)and neural stem cells(NSCs)were transplanted into the ischemic brain established by middle cerebral artery occlusion surgery.Positron emission tomography imaging and neurological tests were applied to evaluate the metabolic and neurofunctional alterations of rats transplanted with stem cells.Quantitative proteomics was employed to investigate the protein expression profiles in iPSCs-transplanted brain in the subacute and chronic phases of stroke.Compared with NSCs-transplanted rats,significantly increased glucose metabolism and neurofunctional scores were observed in iPSCs-transplanted rats.Subsequent proteomic data of iPSCs-transplanted rats identified a total of 39 differentially expressed proteins in the subacute and chronic phases,which are involved in various ischemic stroke-related biological processes,including neuronal survival,axonal remodeling,antioxidative stress,and mitochondrial function restoration.Taken together,our study indicated that iPSCs have a positive therapeutic effect in ischemic stroke and emphasized the wide-ranging microenvironmental changes in the subacute and chronic phases.Yao Chen Fahuan Song Mengjiao Tu Shuang Wu Xiao He Hao Liu Caiyun Xu Kai Zhang Yuankai Zhu Rui Zhou Chentao Jin Ping Wang Hong Zhang Mei Tian 2022Frontiers of Medicine2022,16,3:1
