| 1 | Core-shell fibrous vascular grafts with the nitric oxide releasing property显示文摘Small-diameter vascular grafts with the nitric oxide(NO) releasing property were designed and prepared.Diazeniumdiolated N,N'-dibutyl-1,6-hexanediamine(DBHD/N2O2) was first synthesized as the NO donor and doped into the biocompatible polymer poly(ε-caprolactone)(PCL).The fibrous vascular grafts were fabricated by electrospinning.Despite the reduced platelet adhesion observed on the NO releasing grafts,the cytotoxicity and burst release were apparent,especially at a higher loading level of the NO donor.In order to solve this problem,core-shell structured nanofibers,in which PCL or gelatin is the shell and PCL doped with the NO donor is the core,were fabricated via coaxial electrospinning.The core-shell structure made the NO release more steady and controllable,and the cell compatibility was improved. | ZHANG Lei,WANG Kai,ZHAO Qiang,ZHENG WenTing,WANG ZhiHong,WANG ShuFang & KONG DeLing Key Laboratory of Bioactive Materials,Ministry of Education College of Life Science,Nankai University,Tianjin 300071,China | 2010 | Science China Chemistry2010，53，3： | 6 |
| 2 | Generation and characterization of stable pig pregastrulation epiblast stem cell lines显示文摘Pig epiblast-derived pluripotent stem cells are considered to have great potential and broad prospects for human therapeutic model developme nt and livestock breeding.Despite on going attempts since the 1990s,no stably defined pig epiblast-derived stem cell line has bee n established.Here,guided by in sights from a large-scale sin gle-cell tran scriptome an alysis of pig embryos from embryonic day(E)0 to E14,specifically,the tracing of pluripotency changes during epiblast development,we developed an in vitro culture medium for establishing and maintaining stable pluripotent stem cell lines from pig E10 pregastrulation epiblasts(pgEpiSCs).Enabled by chemical inhibition of WNT-related signaling in combination with growth factors in the FGF/ERK,JAK/STAT3,and Activin/Nodal pathways,pgEpiSCs maintain their pluripotency transcriptome features,similar to those of E10 epiblast cells,and normal karyotypes after more than 240 passages and have the potential to differentiate into three germ layers.Strikingly,ultradeep in situ Hi-C analysis revealed functional impacts of chromatin 3D-spatial associations on the transcriptional regulation of pluripote ncy marker genes in pgEpiSCs.I n practice,we con firmed that pgEpiSCs readily tolerate at least three rounds of successive gene editi ng and gene rated cloned gen e-edited live piglets.Our findings deliver on the long-a nticipated promise of pig pluripote nt stem cells and open new avenues for biological research,animal husbandry,and regenerative biomedicine. | Minglei Zhi Jinying Zhang Qianzi Tang Dawei Yu Shuai Gao Dengfeng Gao Pengliang Liu Jianxiong Guo Tang Hai Jie Gao Suying Cao Zimo Zhao Chongyang Li Xiaogang Weng Mengnan He Tianzhi Chen Yingjie Wang Keren Long Deling Jiao Guanglei Li Jiaman Zhang Yan Liu Yu Lin Daxin Pang Qianqian Zhu Naixin Chen Jingjing Huang Xinze Chen Yixuan Yao Jingcang Yang Zicong Xie Xianya Huang Mengxin Liu Ran Zhang Qiuyan Li Yiliang Miao Jianhui Tian Xingxu Huang Hongsheng Ouyang Bofeng Liu Wei Xie Qi Zhou Zhonghua Liu Caihong Zheng Mingzhou Li Jianyong Han | 2022 | Cell Research2022，32，4： | 3 |
| 3 | The “1-3-7” Approach to Malaria Surveillance and Response--Henan Province, China, 2012−2018显示文摘What is already known about this topic?The“1-3-7”approach to malaria surveillance and response was a key measure for malaria elimination in China and was first introduced into the World Health Organization(WHO)as an international guideline for malaria surveillance and response in 2018.What is added by this report?The“1-3-7”approach was well implemented in Henan Province from 2012−2018.Over this study period,a total of 1,294 malaria cases were detected and reported,and all cases were diagnosed and reported within 1 day with 99.23%(1,284/1,294)of cases were investigated within 3 days.In addition,93.7%(1,212/1,294)of foci were investigated and vector control was implemented within 7 days at all residual non-active foci to prevent further spread.What are the implications for public health practice?The“1-3-7”controlling pattern would be an effective and approachable method for implementation especially in malaria-eliminating countries and regions,but the interval from symptom onset to diagnosis cannot be ignored.Thus,the roles and responsibilities that all actors involved in the health sector must be specified too. | Qunqun Zhang Ying Liu Yabo Hu Yuling Zhao Chengyun Yang Dan Qian Ruimin Zhou Suhua Li Zhou Guan Deling Lu Hongwei Zhang Wanshen Guo | 2020 | China CDC weekly2020，2，17： | 3 |

| 5 | In situ cardiac regeneration by using neuropeptide substance P and IGF-1C peptide eluting heart patches显示文摘Cardiovascular diseases cause huge socio-economic burden worldwide.Although a mammalian myocardium has its own limited healing capability,scaffold materials capable of releasing stem cell recruiting/engrafting factors may facilitate the regeneration of the infarcted myocardium.The aim of this research was to develop cardiac patches capable of simultaneously eluting substance P(SP)and insulin-like growth factor-1C(IGF-1C)peptide.Polycaprolactone/collagen type 1-based patches with or without SP and IGF-1C peptide were fabricated by co-electrospinning,which exhibited nanofibrous morphology.SP and IGF-1C/SP patches recruited significantly higher numbers of bone marrow-mesenchymal stem cells than that of the negative control and patch-only groups in vitro.The developed patches were transplanted in an infarcted myocardium for up to 14 days.Mice underwent left anterior descending artery ligation and received one of the following treatments:(i)sham,(ii)saline,(iii)patch-only,(iv)IGF-1C patch,(v)SP patch and(vi)IGF-1C/SP patch.SP and IGF-1C/SP patch-treated groups exhibited better heart function and attenuated adverse cardiac remodeling than that of the saline,patch-only and individual peptide containing cardiac patches.SP patch and IGF-1C/SP patch-treated groups also showed higher numbers of CD31-positive vessels and isolectin B4-positive capillaries than that of other groups.IGF-1C/SP-treated group also showed thicker left ventricular wall in comparison to the saline and patch-only groups.Moreover,IGF-1C/SP patches recruited significantly higher numbers of CD29-positive cells and showed less numbers of Tunel-positive cells compared with the other groups.These data suggest that SP and IGF-1C peptides may act synergistically for in situ tissue repair. | Muhammad Shafiq Yue Zhang Dashuai Zhu Zongxian Zhao Dong-Hwee Kim Soo Hyun Kim Deling Kong | 2018 | Regenerative Biomaterials2018，5，5： | 2 |
| 6 | Self-immolative micellar drug delivery:The linker matters显示文摘Redox-responsive polymer-drug conjugate micelles are excellent nanoscale vehicles for self-immolative intracellular drug delivery.To covalently connect the polymer and drug,disulfide-bearing linkers,such as 3,3'-dithiodipropionic acid (DDPA) and 4,4'-dithiodibutyric add (DDBA),are used.In this paper,we report the influence of linker length on the therapeutic outcome of redox-sensitive conjugate micelles.Curcumin was selected as the model drug and it was conjugated to a multivalent methoxy poly(ethylene glycol)-polylysine copolymer with DDPA or DDBA as the linker.The obtained two polymer-curcumin conjugates were amphiphilic and could self-assemble into micelles that have a hydrodynamic diameter less than 100 nm.The loading of curcumin in both micelles was above 20% (w/w).Irrespective of the linker type,micelle disassembly was observed due to the collapse of the disulfide bond in a reducing environment.However,the rate of curcumin release was much faster with the DDBA linker than with the DDPA linker as the side product was a 5-membered ring with a low ring strain.The linker length-induced variation of curcumin release kinetics caused a significant difference in the intracellular drug concentration and a higher cytotoxicity was witnessed in three model cell lines (HeLa,PC3,and 4T1) for the micelles with a DDBA linker compared to those containing a DDPA linker.As expected,this phenomenon was also observed in HeLa tumor-bearing nude mice in vivo.The current work highlights the significance of linker length in engineering redox-responsive on-demand delivery systems. | Xuan Meng Min Gao Jian Deng Di Lu Aiping Fan Dan Ding Deling Kong Zheng Wang Yanjun Zhao | 2018 | Nano Research2018，11，12： | 2 |

| 12 | Reciprocal interaction between vascular niche and sweat gland promotes sweat gland regeneration显示文摘The incorporation of vasculature is known to be effective in tissue or organ functional regeneration.However,a vague understanding of the interaction between epidermal appendages and their vascular niches is a foremost obstacle to obtaining sweat gland(SG)-specific vasculature units.Here,we map their precise anatomical con-nections and report that the interplay between SG cells(SGCs)and the surrounding vascular niche is key for glandular development and homeostasis maintenance.To replicate this interplay in vitro,we used three-dimensional(3D)bioprinting to generate reproducible SGC spheroids from differentiated adipose-derived mesenchymal stem cells(ADSCs).With dermal microvascular endothelial cells(DMECs),sacrificial templates made from poly(ε-caprolactone)(PCL)were fabricated to pattern the vascular niche.This interplay model promoted physiologically relevant vascularized glandular morphogenesis in vitro and in vivo.We identified a reciprocal regulatory mechanism for promoting SGs regeneration via contact-independent cell communication and direct cell-cell interactions between SGs and the vasculature.We envision the successful use of our approach for vascularized organ regeneration in the near future. | Xingyu Yuan Xianlan Duan Enhejirigala Zhao Li Bin Yao Wei Song Yuzhen Wang Yi Kong Shijun Zhu Fanliang Zhang Liting Liang Mengde Zhang Chao Zhang Deling Kong Meifeng Zhu Sha Huang Xiaobing Fu | 2023 | Bioactive Materials2023，，3： | 0 |
