| 1 | Antitumor activities of human autologous cytokineinduced killer(CIK)cells against hepatocellular carcinoma cells in vitro and in vivo显示文摘AIM: To characterize the anticancer function of cytokine-induced killer cells (CIK) and develop an adoptiveimmunotherapy for the patients with primary hepatocellularcarcinoma (HCC), we evaluated the proliferation rate,phenotype and the antitumor activity of human CIK cellsfrom healthy donors and HCC patients in vitro and in vivo.METHODS: Peripheral blood mononuclear cells (PBMC) fronhealthy donors and patients with primary HCC were incubatedin vitro and induced into ClK cells in the presence of variouscytokines such as interferon-gamma (IFN-γ), interleukin-1(IL-1), IL-2, and monoclonal antibody (mAb) against CD3.The phenotype and characterization of CIK cells wereidentified by flow cytometric analysis. The cytotoxicity of CIKcells was determined by 51 Cr release assay.RESULTS: The CIK cells were shown to be a heterogeneouspopulation with different cellular phenotypes. Thepercentage of CD3+/CD56+ positive cells, the dominanteffector cells, in total CIK cells from healthy donors andHCC patients, significantly increased from 0.1-0.13 % at day0 to 19.0-20.5 % at day 21 incubation, which suggested thatthe CD3+ CD56+ positive cells proliferated faster than othercell populations of CIK cells in the protocol used in thisstudy. After 28 day in vitro incubation, the ClK cells frompatients with HCC and healthy donors increased by morethan 300-fold and 500-fold in proliferation cell number,respectively. CIK cells originated from HCC patientspossessed a higher in vitro antitumor cytotoxic activity onautologous HCC cells than the autologous lymphokine-activated killer (LAK) cells and PBMC cells. In in vivoanimal experiment, CIK cells had stronger effects on theinhibition of tumor growth in Balb/c nude mice bearing BEL-7402-producing tumor than LAK cells (mean inhibitory rate,84.7 % vs 52.8 %, P < 0.05) or PBMC (mean inhibitoryrate, 84.7% vs37.1%, P<0.01).CONCLUSION: Autologous CIK cells are of highly efficientcytotoxic effector cells against primary hepatocellularcarcinoma cells and might serve as an alternative adoptivetherapeutic strategy for HCC patients. | Fu-Sheng Wang Ming-Xu Liu Bing Zhang Ming Shi Zhou-Yun Lei Wen-Bing Sun Qing-You Du Ju-Mei Chen,Division of Biological Engineering,Beijing Institute of Infectious Diseases,Beijing 100039,China Wen-Bing Sun,Department of Surgery,Beijing Hospital of Infectious Diseases,Beijing 100039,China | 2002 | World Journal of Gastroenterology2002，8，3： | 108 |

| 6 | Directional hydraulic fracturing to control hard-roof rockburst in coal mines显示文摘Hard roof is the main factor that induces rock-burst.In view of the present obvious weakness of control measures for hard roof rockburst in domestic collieries,the mechanism and field application of directional hydraulic fracturing technology for rock-burst prevention have been investigated in this paper using theoretical analysis and numerical simulation.The results show that the weighting span of the main roof and the released kinetic energy as well as the total elastic energy decreased greatly after the directional fracturing of hard roof with the mining progression,thereby reducing the rockburst hazard degree to coal body.The directional hydraulic fracturing technology was carried out in 6305 working face of Jisan Coal Mine to prevent rockburst.Field practices have proved that this technology is much simpler and safer to operate with better prevention effect compared with blasting.By optimizing the operation procedures and developing a new technology of automated high-pressure delivery pipe,the maximum fracturing radius now reaches more than 9 m and the borehole depth exceeds 20 m.Additionally,drilling cutting method was applied to monitor the stress of the coal mass before and after the fracturing,and the drill cuttings dropped significantly which indicates that the burst prevention effect of directional hydraulic fracturing technology is very remarkable.The research results of this paper have laid a theoretical and practical foundation for the widespread application of the directional hydraulic fracturing technology in China. | Fan Jun Dou Linming He Hu Du Taotao Zhang Shibin Gui Bing Sun Xinglin | 2012 | International Journal of Mining Science and Technology2012，22，2： | 28 |
| 7 | Traditional Chinese medicine for prevention and treatment of hepatocarcinoma: From bench to bedside显示文摘Traditional Chinese medicine(TCM) has played a positive role in the management of hepatocarcinoma. Hepatocarcinoma patients may present Qi-stagnation, damp-heat, blood stasis, Qi-deficiency, Yin-deficiency and other TCM syndromes(Zheng). Modern treatments such as surgery, transarterial chemoembolization(TACE) and high intensity focus ultrasound treatment would influence the manifestation of TCM syndromes. Herbs with traditional efficacy of tonifying Qi, blood and Yin, soothing liver-Qi stagnation, clearing heat and detoxifying and dissolving stasis, have been demonstrated to be potent to prevent hepatocarcinogenesis. TCM has been widely used in all aspects of integrative therapy in hepatocarcinoma, including surgical resection, liver transplantation, TACE, local ablative therapies and even as monotherapy for middle-advanced stage hepatocarcinoma. Clinical practices have confirmed that TCM is effective to alleviate clinical symptoms, improve quality of life and immune function, prevent recurrence and metastasis, delay tumor progression, and prolong survival time in hepatocarcinoma patients. The effective mechanism of TCM against hepatocarcinoma is related to inducing apoptosis, autophagy, anoikis and cell senescence, arresting cell cycle, regulating immune function, inhibiting metastasis and angiogenesis, reversing drug resistance and enhancing effects of chemotherapy. Along with the progress of research in this field, TCM will contribute more to the prevention and treatment of hepatocarcinoma. | Bing Hu Shuang-Shuang Wang Qin Du | 2015 | World Journal of Hepatology2015，7，9： | 22 |

| 11 | Removal of copper ions from aqueous solution by calcium alginate immobilized kaolin显示文摘Kaolin has been widely used as an adsorbent to remove heavy metal ions from aqueous solutions.However,the lower heavy metal adsorption capacity of kaolin limits its practical application.A novel environmental friendly material,calcium alginate immobilized kaolin (kaolin/CA),was prepared using a sol-gel method.The effects of contact time,pH,adsorbent dose,and temperature on Cu 2+ adsorption by kaolin/CA were investigated.The Langmuir isotherm was used to describe the experimental adsorption,the maximum Cu 2+ adsorption capacity of the kaolin/CA reached up to 53.63 mg/g.The thermodynamic studies showed that the adsorption reaction was a spontaneous and endothermic process. | Yanhui Li Bing Xia Quansheng Zhao Fuqiang Liu Pan Zhang Qiuju Du DechangWang Da Li ZonghuaWang Yanzhi Xia | 2011 | Journal of Environmental Sciences2011，23，3： | 14 |
| 12 | Tracing the first hematopoietic stem cell generation in human embryo by single-cell RNA sequencing显示文摘Tracing the emergence of the first hematopoietic stem cells(HSCs)in human embryos,particularly the scarce and transient precursors thereof,is so far challenging,largely due to the technical limitations and the material rarity.Here,using single-cell RNA sequencing,we constructed the first genome-scale gene expression landscape covering the entire course of endothelial-to-HSC transition during human embryogenesis.The transcriptomically defined HSC-primed hemogenic endothelial cells(HECs)were captured at Carnegie stage(CS)12-14 in an unbiased way,showing an unambiguous feature of arterial endothelial cells(ECs)with the up-regulation of RUNX1,MYB and ANGPTL Importantly,subcategorizing CD34+CD45-ECs into a CD44+population strikingly enriched HECs by over 10-fold.We further mapped the developmental path from arterial ECs via HSC-primed HECs to hematopoietic stem progenitor cells,and revealed a distinct expression pattern of genes that were transiently over-represented upon the hemogenic fate choice of arterial ECs#including EMCN,PROCR and RUNX1T1.We also uncovered another temporally and molecularly distinct intra-embryonic HEC population,which was detected mainly at earlier CS 10 and lacked the arterial feature.Finally,we revealed the cellular components of the putative aortic niche and potential cellular interactions acting on the HSCprimed HECs.The cellular and molecular programs that underlie the generation of the first HSCs from HECs in human embryos,together with the ability to distinguish the HSC-primed HECs from others,will shed light on the strategies for the production of clinically useful HSCs from pluripotent stem cells. | Yang Zeng Jian He Zhijie Bai Zongcheng Li Yandong Gong Chen Liu Yanli Ni Junjie Du Chunyu Ma Lihong Bian Yu Lan Bing Liu | 2019 | Cell Research2019，29，11： | 14 |
| 13 | Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event. | TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou | 2018 | Science China(Physics,Mechanics & Astronomy)2018，61，3： | 12 |
| 14 | Fabrication and Testing of Carbon Fiber Reinforced Truss Core Sandwich Panels显示文摘Truss core sandwich panels reinforced by carbon fibers were assembled with bonded laminate facesheets and carbon fiber reinforced truss cores.The top and bottom facesheets were interconnected with truss cores.Both ends of the truss cores were embedded into four layers of top and bottom facesheets.The mechanical properties of truss core sandwich panels were then investigated under out-of-plane and in-plane compression loadings to reveal the failure mechanisms of sandwich panels.Experimental results indicated that the mechanical behavior of sandwich structure under in-plane loading is dominated by the buckling and debonding of facesheets. | Bing Wang Linzhi Wu Li Ma Qiang Wang Shanyi Du | 2009 | Journal of Materials Science & Technology2009，25，4： | 10 |
| 15 | Effect of emodin on pancreatic fi brosis in rats显示文摘AIM: To establish the rats model of chronic fibrosing pancreatitis and to prove the anti-fibrotic effect of emodin in chronic pancreatitis with fi brosis. METHODS: Fifty rats were randomly divided into five groups, 10 rats in each group. Trinitrobenzene sulfonic acid (TNBS) was infused into the pancreatic duct to induce chronic pancreatitis in rats (except for normal group). Emodin-treated rats were fed with different doses of emodin (20, 40 and 80 mg/kg body weight) for 28 d, while normal group and control group received 0.9% sodium chloride solution. Serum levels of hyaluronic acid (HA) and laminin (LN) were determined by radioimmunoassay. Histopathological alterations were studied by optical microscopy. Expression of collagen was also examined while transforming growth factor-beta-1 (TGF-β1) was localized by immunochemistry. RESULTS: In emodin-treated rats, the serum levels of HA and LN were decreased significantly (HA, 62.2 ± 19.3 μg/L vs 112.7 ± 26.5 μg/L, P < 0.05; LN 44.3 ± 10.4 μg/L vs 86.2 ± 16.5 μg/L, P < 0.05); the degree of fibrosis was ameliorated observably; the expression of collagen in pancreatic tissue was reduced especially in high-dose emodin-treated group (36% ± 5% vs 42% ± 6%, P < 0.05); with the increased doses of emodin, the expression of TGF-β1 was declined, compared with those in control group. CONCLUSION: Emodin has an anti-fibrotic effect on pancreatic fibrosis in rats. Because of its anti-fibrotic effect, it could be a potential herb for the treatment of chronic pancreatitis. | Cai-Hua Wang Zhi-Qiang Gao Bing Ye Jian-Ting Cai Chuan-Gao Xie Ke-Da Qian Qin Du | 2007 | World Journal of Gastroenterology2007，13，3： | 10 |
| 16 | Impacts of mixed litter decomposition from Robinia pseudoacacia and other tree species on C loss and nutrient release in the Loess Plateau of China显示文摘The productivity of Robinia pseudoacacia(R.p.) pure forest usually declines at the late growth stage,and reforming it into mixed forests could be a promising way to resolve this problem. When choosing a suitable tree species that can be mixed with R.p., the interspecific relationship is an important issue. Therefore, we gathered the autumn litter fall from R.p. and 10 other species from the Loess Plateau of China were mixed in dual species litterbags(R.p.+each other species) and buried them in soil for a 345 days lab decay incubation. We measured the litter mass loss and nutrient contents to determine whether the nutrient release was affected by mixed species litter decomposition. The impacts of mixed litter decomposition on macro-elements release were more obvious than on micro-elements. The litters with similar substrate quality might show variable impacts on nutrients release in mixed decomposition. The C loss and release of nutrient was improved by descending order when R.p. litter was mixed with Hippophae rhamnoides, Ulmus pumila, Populus simonii, Larix principis-rupprechtii and Quercus liaotungensis(Q.l.). But, except for Q.l., only the other species were recommended as suitable mix-plants for R.p. since promoting a high turnover of the nutrient in the litter compartment and a rapid availability for tree. | Xiaoxi Zhang Zengwen Liu Bochao Zhu Yuanhao Bing Nhu Trung Luc Liangzhen Du Zhenhua Zhu | 2016 | Journal of Forestry Research2016，27，3： | 10 |

| 19 | Enhancing effect of natural borneol on the absorption of geniposide in rat via intranasal administration显示文摘Both geniposide (Ge) and natural borneol (NB) are bioactive substances derived from traditional Chinese herbs. The effect of NB on the pharmacokinetics of Ge in rat via intranasal administration was investigated. The concentrations of Ge in plasma were determined by reversed-phase high-performance liquid chromatography (HPLC) after intranasal administration of Ge (4 mg/kg) alone and combined with different doses (0.08, 0.8, and 8 mg/kg) of NB. The intravenous administration was given as a reference (4 mg/kg of Ge and 8 mg/kg of NB). Compared with the intravenous administration, the absolute bioavailability of Ge was 76.14% through intranasal administration combined with NB. Compared with the intranasal administration of Ge alone, Ge could be absorbed rapidly in the nasal cavity combined with NB; the peak time of Ge in the plasma became shorter (3-5 min vs. 40 min); the peak concentration became higher (1.32-4.25 μg/ml vs. 0.67 μg/ml); and, the relative bioavailability of Ge combined with NB was 90.3%-237.8%. The enhancing effect was attenuated as the dose of NB decreased. The results indicated that NB can accelerate the absorption of Ge dose-dependently in the nasal cavity. | Yang LU Shou-ying DU Xiao-lan CHEN Qing WU Xiao SONG Bing XU Yong-song ZHAI | 2011 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2011，12，2： | 8 |
| 20 | Presenilin 2 deficiency facilitates Aβ-induced neuroinflammation and injury by upregulating P2X7 expression显示文摘Accumulating evidence suggests that β-amyloid (Aβ)-induced neuroinflammation plays a prominent and early role in Alzheimer’s disease (AD). In this study, we demonstrated that Presenilin 2 (PS2) deficiency facilitates Aβ-induced neuroinflammation and injury by upregulating P2X7 expression both in vitro and in vivo. PS2 knockout mice demonstrated increased cognitive impairments and cerebral injury. PS2 deficiency increased the expression of P2X7 both in neurons and microglial cells.Furthermore, extracellular ATP also increased in both Aβ-treated and untreated PS2 knockout microglial cells. Notably, Aβ-induced classical proinflammatory cytokines such as IL-1β, IL-1α and TNF-α were increased in PS2 knockout microglial cells, suggesting a potential role for PS2 in the regulation of neuroinflammation. The expression of P2X7 clearly increased in PS2 knockdown BV2 cells. Consistent with in vivo data, Aβ-induced IL-1β production was also clearly enhanced in PS2 knockdown BV2 cells. Additionally, expression of the transcription factor Sp1 was increased in PS2 knockdown cells. When we treated PS2 knockdown cells with the specific Sp1 inhibitor MIT, we observed that enhanced P2X7 expression was significantly rescued. Taken together, these data suggests that PS2 plays a protective role during Aβ-induced neuroinflammation and injury through down-regulation of P2X7 expression. | Juliang Qin Xiaoyu Zhang Ziqiang Wang Jinju Li Zhen Zhang Liangcai Gao Hua Ren Min Qian Bing Du | 2017 | Science China(Life Sciences)2017，60，2： | 7 |
