3Immune modulatory function of abundant immune-related microRNAs in microvesicles from bovine colostrum显示文摘Colostrum provides essential nutrients and immunologically active factors that are beneficial to newborns.Our previous work demonstrated that milk contains large amounts of miRNA that is largely stored in milk-derived microvesicles(MVs).In the present study,we found that the MVs from colostrum contain signifi cantly higher levels of several immune-related miRNAs.We hypothesized that the colostrum MVs may transfer the immune-related miR-NAs into cells,which contribute to its immune modulatory feature.We isolated colostrum MVs by ultracentrifugation and demonstrated several immune modulation features associated with miRNAs.We also provide evidence that the physical structure of milk-derived MVs is essential for transfer miRNAs and following immune modulation effect.Moreover,we found that colostrum powder-derived MVs also contains higher levels of immune-related miRNAs that display similar immune modulation effects.Taken together,these results show that MV-containing immunerelated miRNAs may be a novel mechanism by which co-lostrum modulates body immune response.Qi Sun Xi Chen Jianxiong Yu Ke Zen Chen-Yu Zhang Liang Li 2013Protein & Cell2013,4,3:14
4Secretory/releasing proteome-based identification of plasma biomarkers in HBV-associated hepatocellular carcinoma显示文摘For successful therapy, hepatocellular carcinoma (HCC) must be detected at an early stage. Herein, we used a proteomic approach to analyze the secretory/releasing proteome of HCC tissues to identify plasma biomarkers. Serum-free conditioned media (CM) were collected from primary cultures of cancerous tissues and surrounding noncancerous tissues. Proteomic analysis of the CM proteins permitted the identification of 1365 proteins. The enriched molecular functions and biological processes of the CM proteins, such as hydrolase activity and catabolic processes, were consistent with the liver being the most important metabolic organ. Moreover, 19% of the proteins were characterized as extracellular or membrane-bound. For validation, secretory proteins involved in transforming growth factor-β signaling pathways were validated in plasma samples. Alphafetoprotein (AFP), metalloproteinase (MMP)1, osteopontin (OPN), and pregnancy-specific beta-1-glycoprotein (PSG)9 were significantly increased in HCC patients. The overall performance of MMP1 and OPN in the diagnosis of HCC remained greater than that of AFP. In addition, this study represents the first report of MMP1 as a biomarker with a higher sensitivity and specificity than AFP. Thus, this study provides a valuable resource of the HCC secretome with the potential to investigate serological biomarkers. MMP1 and OPN could be used as novel biomarkers for the early detection of HCC and to improve the sensitivity of biomarkers compared with AFP.YANG Lei RONG WeiQi XIAO Ting ZHANG Ying XU Bin LIU Yu WANG LiMing WU Fan QI Jun ZHAO XiuYing WANG HongXia HAN NaiJun GUO SuPing WU JianXiong GAO YanNing CHENG ShuJun 2013Science China(Life Sciences)2013,56,7:9

6Constructing a high-density linkage map for Gossypium hirsutum × Gossypium barbadense and identifying QTLs for lint percentage显示文摘To introgress the good fiber quality and yield from Gossypium barbadense into a commercial Upland cotton variety, a high-density simple sequence repeat(SSR) genetic linkage map was developed from a BC1F1 population of Gossypium hirsutum×Gossypium barbadense. The map comprised 2,292 loci and covered 5115.16 centi Morgan(c M) of the cotton AD genome, with an average marker interval of 2.23 c M. Of the marker order for 1,577 common loci on this new map, 90.36% agrees well with the marker order on the D genome sequence genetic map. Compared with five published high-density SSR genetic maps, 53.14% of marker loci were newly discovered in this map. Twenty-six quantitative trait loci(QTLs) for lint percentage(LP) were identified on nine chromosomes. Nine stable or common QTLs could be used for marker-assisted selection. Fifty percent of the QTLs were from G. barbadense and increased LP by 1.07%–2.41%. These results indicated that the map could be used for screening chromosome substitution segments from G. barbadense in the Upland cotton background, identifying QTLs or genes from G. barbadense, and further developing the gene pyramiding effect for improving fiber yield and quality.Yuzhen Shi Wentan Li Aiguo Li Ruihua Ge Baocai Zhang Junzhi Li Guangping Liu Junwen Li Aiying Liu Haihong Shang Juwu Gong Wankui Gong Zemao Yang Feiyü Tang Zhi Liu Weiping Zhu Jianxiong Jiang Xiaonan Yu Tao Wang Wei Wang Tingting Chen Kunbo Wang Zhengsheng Zhang Youlu Yuan 2015Journal of Integrative Plant Biology2015,57,5:7
7Adjuvant radiotherapy in central hepatocellular carcinoma after narrow-margin hepatectomy:A 10-year real-world evidence显示文摘Objective:A prospective randomized control study investigated the feasibility and efficacy of adjuvant radiotherapy on patients with central hepatocellular carcinoma(HCC)after narrow-margin hepatectomy(<1 cm).This study presents an updated 10-year real-world evidence to further characterize the role of adjuvant radiotherapy.Methods:Patients with central HCC after narrow-margin hepatectomy(<1 cm)were prospectively assigned to adjuvant radiotherapy group and control group.Patients'outcome,adverse events,long-term recurrence and survival rates were investigated.Results:The 1-,5-,and 10-year recurrence-free survival(RFS)rates were 81.0%,43.9%,and 38.7%,respectively in adjuvant radiotherapy group and 71.7%,35.8%,and 24.2%,respectively in control group(log-rank test,P=0.09).The 1-,5-,and 10-year overall survival(OS)rates were 96.6%,54.7%,and 42.8%,respectively in adjuvant radiotherapy group and 90.2%,55.1%,and 30.0%,respectively in control group(log-rank test,P=0.20).The 1-,5-,and 10-year RFS rates for patients with small HCC(≤5 cm)were 91.1%,51.6%,and 48.4%,respectively in adjuvant radiotherapy group and 80.0%,36.6%,and 26.6%,respectively in control group(log-rank test,P=0.03).Landmark analysis demonstrated that patients with small HCC in adjuvant radiotherapy group had a significantly improved OS in second five years after treatment in comparison to patients in control group(log-rank test,P=0.05).Conclusions:Our updated results showed a sustained clinical benefit on reducing recurrence,improving longterm survival for small central HCC by adjuvant radiotherapy after narrow-margin hepatectomy.Long-term survival data also indicated that hepatectomy is an optimal treatment for selected patients with central HCC.Weiqi Rong Weibo Yu Liming Wang Fan Wu Kai Zhang Bo Chen Chengli Miao Liguo Liu Songlin An Changcheng Tao Weihu Wang Jianxiong Wu 2020Chinese Journal of Cancer Research2020,32,5:6
8Biomechanical properties of acellular sciatic nerves treated with a modified chemical method显示文摘Nerve grafts are able to adapt to surrounding biomechanical environments if the nerve graft itself exhibits appropriate biomechanical properties (load, elastic modulus, etc.). The present study was designed to determine the differences in biomechanical properties between fresh and chemically acellularized sciatic nerve grafts. Two different chemical methods were used to establish acellular nerve grafts. The nerve was chemically extracted in the Sondell method with a combination of Triton X-100 (nonionic detergent) and sodium deoxycholate (anionic detergent), and in the modified method with a combination of Triton X-200 (anionic detergent), sulfobetaine-10 (SB-10, amphoteric detergents), and sulfobetaine-16 (SB-16, amphoteric detergents). Following acellularization, hematoxylin-eosin staining and scanning electron microscopy demonstrated that the effect of acellularization via the modified method was similar to the traditional Sondell method. However, effects of demyelination and nerve fiber tube integrity were superior to the traditional Sondell method. Biomechanical testing showed that peripheral nerve graft treated using the chemical method resulted in decreased biomechanical properties (ultimate load, ultimate stress, ultimate strain, and mechanical work to fracture) compared with fresh nerves, but the differences had no statistical significance (P > 0.05). These results demonstrated no significant effect on biomechanical properties of nerves treated using the chemical method. In conclusion, nerve grafts treated via the modified method removed Schwann cells, preserved neural structures, and ensured biomechanical properties of the nerve graft, which could be more appropriate for implantation studies.Xinlong Ma Zhao Yang Xiaolei Sun Jianxiong Ma Xiulan Li Zhenzhen Yuan Yang Zhang Honggang Guo 2011Neural Regeneration Research2011,6,4:6
9Paleoenvironmental implications of high-density records in Co-rich seamount crusts from the Pacific Ocean显示文摘Co-rich seamount crusts have been shown to possess great potential for providing information on paleoceanographic and paleoclimatic changes. High resolution data are essential to decipher and correctly understand such high-density records. With the development of modern microprobe techniques, detailed sampling of crusts can be performed and it is possible to retrieve detailed information about envi- ronmental changes recorded in the seamount crusts. We report here geochemical results of more than 40 elements (including all rare earth elements) of four Co-rich seamount crust samples, which were collected from seamounts in the central and western Pacific Ocean. These data were obtained with two micro-probe techniques: Electron Probe Micro Analyzer and Laser Ablation Inductively Coupled Plasma Mass Spectrometry. The chronological framework of the seamount crust samples was determined using the cos- mogenic 10Be and the Co-chronometer. Records of elemental composition, P, and Al/(Fe + Mn) and Y/Ho ratios across the sections of the four samples are used to identify paleoceanographic and paleoclimatic events over the past ~30 Ma. These data show that: (1) Al/(Fe + Mn) in the western Pacific seamount crust is a useful proxy for the assessment of changes of source materials related to the variability of the Asian monsoon; (2) P and Y/Ho can be used as proxies to infer biogenic episodes. Finally we discuss the methodology related to dating and micro-probe analysis used in crust study.WANG XiaoHong ZHOU LiPing WANG YiMin ZHANG XueHua LIU XiaoMing FAN XingTao LIU KeXin ZHOU JianXiong 2008Science China Earth Sciences2008,51,10:5
10Post-surgical resection prognostic value of combined OPN, MMP7, and PSG9 plasma biomarkers in hepatocellular carcinoma显示文摘Biomarkers for hepatocellular carcinoma (HCC) following curative resection are not currently sufficient for prognostic indication of overall survival (OS) and disease-free survival (DFS). The aim of this study was to investigate the prognostic performance of osteopontin (OPN), matrix metalloproteinase 7 (MMP7), and pregnancy specific glycoprotein 9 (PSG9) in patients with HCC. A total of 179 prospective patients with HCC provided plasma before hepatectomy. Plasma OPN, MMP7, and PSG9 levels were determined by enzyme-linked immunosorbent assay. Correlations between plasma levels, clinical parameters, and outcomes (OS and DFS) were overall analyzed. High OPN (≥149.97 ng/mL), MMP7 (≥2.28 ng/mL), and PSG9 (≥45.59 ng/mL) were prognostic indicators of reduced OS (P<0.001, P<0.001, and P=0.007, respectively). Plasma PSG9 protein level was an independent factor in predicting OS (P=0.008) and DFS (P=0.038). Plasma OPN+MMP7+PSG9 elevation in combination was a prognostic factor for OS (P<0.001). OPN was demonstrated to be a risk factor-associated OS in stage I patients with HCC and patients with low α-fetoprotein levels (<20 ng/mL). These findings suggested that OPN, MMP7, PSG9 and their combined panels may be useful for aiding in tumor recurrence and mortality risk prediction of patients with HCC, particularly in the early stage of HCC carcinogenesis.Weiqi Rong Yang Zhang Lei Yang Lin Feng Baojun Wei Fan Wu Liming Wang Yanning Gao Shujun Cheng Jianxiong Wu Ting Xiao 2019Frontiers of Medicine2019,13,2:5

12MATRIEX imaging:multiarea two-photon real-time in vivo explorer显示文摘Two-photon laser scanning microscopy has been extensively applied to study in vivo neuronal activity at cellular and subcellular resolutions in mammalian brains.However,the extent of such studies is typically confined to a single functional region of the brain.Here,we demonstrate a novel technique,termed the multiarea two-photon real-time in vivo explorer(MATRIEX),that allows the user to target multiple functional brain regions distributed within a zone of up to 12mm in diameter,each with a field of view(FOV)of ~200μm in diameter,thus performing two-photon Ca2+imaging with single-cell resolution in all of the regions simultaneously.For example,we demonstrate real-time functional imaging of single-neuron activities in the primary visual cortex,primary motor cortex and hippocampal CA1 region of mice in both anesthetized and awake states.A unique advantage of the MATRIEX technique is the configuration of multiple microscopic FOVs that are distributed in three-dimensional space over macroscopic distances(>1 mm)both laterally and axially but that are imaged by a single conventional laser scanning device.In particular,the MATRIEX technique can be effectively implemented as an add-on optical module for an existing conventional single-beam-scanning two-photon microscope without requiring any modification to the microscope itself.Thus,the MATRIEX technique can be readily applied to substantially facilitate the exploration of multiarea neuronal activity in vivo for studies of brain-wide neural circuit function with single-cell resolution.Mengke Yang Zhenqiao Zhou Jianxiong Zhang Shanshan Jia Tong Li Jiangheng Guan Xiang Liao Bing Leng Jing Lyu Kuan Zhang Min Li Yan Gong Zhiming Zhu Junan Yan Yi Zhou Jian K Liu Zsuzsanna Varga Arthur Konnerth Yuguo Tang Jinsong Gao Xiaowei Chen Hongbo Jia 2019Light(Science & Applications)2019,8,1:4
13Crystalline behaviors and phase transition during the manufacture of fine denier PA6 fibers显示文摘Recently we have successfully produced fine denier PA6 fibers by using additives containing lanthanide compounds.Meanwhile,crystallization and phase transition of PA6 fibers during spinning and drawing processes were investigated.During the spinning process,β phase crystal could be obtained in as-spun PA6 fibers which were produced with relatively high melt draw ratio,while γ phase crystal predominated when the melt draw ratio was relatively low.β phase crystal,whose behaviors are similar with those of γ phase by FT-IR and XRD characterization,could be transformed to α form easily when PA6 fibers are immersed in boiling water.However,γ phase crystal of PA6 remains unchanged in boiling water.Thus,β and γ phase crystals of PA6 can be differentiated by the crystalline behaviors of PA6 fibers after treatment in boiling water.Further experiments demonstrate that the β phase can also be produced during a drawing process where a phase transformation from γ to α occurs.In other words,β phase may act as an intermediate state during the phase transformation.ZHANG ChengFeng LIU YuHai LIU ShaoXuan LI HuiZhen HUANG Kun PAN QingHua HUA XiaoHui HAO ChaoWei MA QingFang LV ChangYou LI WeiHong YANG ZhanLan ZHAO Ying WANG DuJin LAI GuoQiao JIANG JianXiong XU YiZhuang WU JinGuang 2009Science China Chemistry2009,52,11:4
14Deep learning-enabled triboelectric smart socks for IoT-based gait analysis and VR applications显示文摘The era of artificial intelligence and internet of things is rapidly developed by recent advances in wearable electronics.Gait reveals sensory information in daily life containing personal information,regarding identification and healthcare.Current wearable electronics of gait analysis are mainly limited by high fabrication cost,operation energy consumption,or inferior analysis methods,which barely involve machine learning or implement nonoptimal models that require massive datasets for training.Herein,we developed low-cost triboelectric intelligent socks for harvesting waste energy from low-frequency body motions to transmit wireless sensory data.The sock equipped with self-powered functionality also can be used as wearable sensors to deliver information,regarding the identity,health status,and activity of the users.To further address the issue of ineffective analysis methods,an optimized deep learning model with an end-to-end structure on the socks signals for the gait analysis is proposed,which produces a 93.54%identification accuracy of 13 participants and detects five different human activities with 96.67%accuracy.Toward practical application,we map the physical signals collected through the socks in the virtual space to establish a digital human system for sports monitoring,healthcare,identification,and future smart home applications.Zixuan Zhang Tianyiyi He Minglu Zhu Zhongda Sun Qiongfeng Shi Jianxiong Zhu Bowei Dong Mehmet Rasit Yuce Chengkuo Lee 2020npj Flexible Electronics2020,4,1:4
15DYNAMIC PRICING UNDER TEMPERATURE CONTROL FOR PERISHABLE FOODS显示文摘Consumers pay more and more attention to the quality of perishable foods,which is mainly affected by storage temperature.This paper presents a dynamic pricing model for perishable foods under temperature control.To maximize the total profit,the optimal price and storage temperature are obtained using Pontryagin's maximum principle.A static pricing model is provided to compare with the dynamic one.It is shown by a numerical example that the dynamic policy can make more revenue than the static one.Moreover,the managerial implications are analyzed and the effectiveness of the proposed method is demonstrated.Wenwen Liu Wansheng Tang Lin Feng Jianxiong Zhang 2014Journal of Systems Science and Systems Engineering2014,23,3:3
16Generation 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 2022Cell Research2022,32,4:3
17Development of FGF-2-loaded electrospun waterborne polyurethane fibrous membranes for bone regeneration显示文摘Guided bone regeneration(G BR)membrane has been used to improve functional outcomes for periodontal regener ation.However,few studies have focused on the biomimetic membrane mim-icking the vascularization of the periodontal membrane.This study aimed to fabricate waterborne polyurethane(WPU)fibrous membranes loaJed fibroblast growth factor-2(FGF-2)via emulsion electrospinning,which can promote regeneration of periodontal tissue via the vascularization of the biomimetic GBR membrane.A biodegradable WPU was synthesized by using lysine and dime-thylpropionic acid as chain extenders according to the rule of green chemical synthesis technology.The WPU fibers with FGF-2 was fabricated via emulsion electrospinning.The results confirmed that controlled properties of the fibrous membrane had been achieved with controlled degradation,suitable mech anical properties and sustained release of the factor.The immunohistochemical expression of angiogenic-related factors was positive,meaning that FGF-2 loaded in fibers can sig-nificantly promote cell vasculariz ation.The fiber scaffold loaded FGF-2 has the potential to be used as a functional GBR membrane to promote the formation of extraosseous blood vessels during periodontal repairing.Chi Zhang Jianxiong Wang Yujie Xie Li Wang Lishi Yang Jihua Yu Akira Miyamoto Fuhua Sun 2021Regenerative Biomaterials2021,8,1:3
18Unfolding the fast neutron spectra of a BC501A liquid scintillation detector using GRAVEL method显示文摘Accurate knowledge of the neutron energy spectra is useful in basic research and applications. The overall procedure of measuring and unfolding the fast neutron energy spectra with BC501 A liquid scintillation detector is described. The recoil proton spectrum of 241Am-Be neutrons was obtained experimentally. With the NRESP7 code, the response matrix of detector was simulated.Combining the recoil proton spectrum and response matrix, the unfolding of neutron spectra was performed by GRAVEL iterative algorithm. A MatLab program based on the GRAVEL method was developed. The continuous neutron spectrum of 241Am-Be source and monoenergetic neutron spectrum of D-T source have been unfolded successfully and are in good agreement with their standard reference spectra. The unfolded 241Am-Be spectrum are more accurate than the spectra unfolded by artificial neural networks in recent years.CHEN YongHao CHEN XiMeng LEI JiaRong AN Li ZHANG XiaoDong SHAO JianXiong ZHENG Pu WANG XinHua 2014Science China(Physics,Mechanics & Astronomy)2014,57,10:3

20The role of intraoperative electron radiotherapy in centrally located hepatocellular carcinomas treated with narrow-margin (<1 cm) hepatectomy: a prospective, phase 2 study显示文摘Background: Postoperative radiotherapy (RT) is known to play an important role in the treatment of hepatocellular carcinomas (HCCs), but the specific role of intraoperative electron radiotherapy (IOERT) in HCCs remains unclear. The aim of this study was to investigate the safety and efficacy of IOERT in centrally located HCCs treated with narrow-margin (<1 cm) hepatectomy. Methods: This was a single-center, phase 2, prospective non-randomized controlled study, including 268 patients with centrally located HCCs who underwent narrow-margin hepatectomy. The patients were subsequently allocated to the IOERT group (n=59) or to the control group (n=65). The primary outcome of the study was to compare recurrence-free survival (RFS) between the IOERT group and the control group, and the secondary outcome was to compare overall survival (OS) rate between the two groups. Results: Of 268 patients enrolled, a total of 124 were included in the study: 59 in IOERT group, 65 in control group. The 1-, 2-, 3-year RFS rates were 79.3%, 62.1% and 45.8% for patients in the IOERT group, and 47.6%, 28.6%, and 22.9% for patients in the control group, respectively (P=0.025). The 1-, 2-, and 3-year OS rates were 100.0%, 94.9%, and 83.7% for patients in the IOERT group, and 92.3%, 87.5%, and 79.4% for patients in the control group, respectively (P=0.314). Subgroup analysis of MVI (+) patients revealed that RFS and OS are significantly prolonged in the IOERT subgroup as compared to the control, whereas there was no significant difference of RFS and OS between the two groups in MVI (−) patients. Conclusions: IOERT for centrally located HCCs with concurrent narrow-margin hepatectomy was feasible and safe. Statistically better RFS rate was observed in the IOERT group compared to the control group. Subgroup analysis revealed that IOERT was more beneficial for postoperative survival of HCC patients with MVI.
