| 1 | Molecular mechanism of hepatitis B virus X protein function in hepatocarcinogenesis显示文摘Many factors are considered to contribute to hepatitis B virus(HBV)-associated hepatocellular carcinoma(HCC),including products of HBV,HBV integration and mutation,and host susceptibility. HBV X protein(HBx) can interfere with several signaling pathways associated with cell proliferation and invasion,and HBx C-terminal truncation has been suggested to impact the development of HCC. This review focuses on the pathological functions of HBx in HBV-induced hepatocarcinogenesis. As a transactivator,HBx can affect regulatory non-coding RNAs(nc RNAs),including micro RNAs and long nc RNAs. HBx is also involved in epigenetic modification and DNA repair. HBx interacts with various signal-transduction pathways,such as the p53,Wnt,and nuclear factor-κB pathways. We conclude that HBx hastens the development of hepatoma. | Ming Geng Xuan Xin Li-Quan Bi Lu-Ting Zhou Xiao-Hong Liu | 2015 | World Journal of Gastroenterology2015，21，38： | 24 |

| 3 | Loss of Wnt5a and Ror2 protein in hepatocellular carcinoma associated with poor prognosis显示文摘AIM:To investigate the expression and clinical significance of Wnt member 5a (Wnt5a) and receptor tyrosine kinase-like orphan receptor 2 (Ror2) in hepatocellular carcinoma (HCC).METHODS:In HCC tissues obtained from 85 patients,the protein expressions of Wnt5a,Ror2,β-catenin,and Ki-67 via immunohistochemical staining using the Envision Plus System.The antibody binding was visualized with 3,3'-diaminobenzidine tetrahydrochloride (DAB) before brief counterstaining with Mayer's hematoxylin.The degree of immunohistochemical staining was recorded using a semiquantitative and subjective grading system.The mRNA expression of Ror2 was examined by real-time reverse transcription polymerase chain reaction,including nineteen of the 85 HCC and three normal liver tissues.The ratios of Ror2 to the housekeeping gene GAPDH represented the normalized relative levels of Ror2 expression.To determine the prognostic factor,the outcome of the 82 patients was determined by reviewing their medical charts.The overall and disease-free survival rates were estimated using the Kaplan-Meier method and compared with the log-rank test.The prognostic analysis was carried out with univariate and multivariate Cox regressions models.RESULTS:Compared to nontumorous (hepatitis or cirrhotic) tissues,Ror2 mRNA expression was clearly decreased in HCC.Ror2 and Wnt5a protein expressions in the majority of HCC patients (63% and 77%,respectively) was significantly less in tumor tissues,as compared to adjacent nontumorous tissues,and this reduction was correlated with increasing serum α-fetoprotein and tumor stage.In 68% (58/85) of the HCC cases,the expression of β-catenin in tumor tissues was either downregulated in the cellular membrane,upregulated in the cytoplasm,or both.Survival analysis indicated that Wnt5a and Ror2 protein expressions could be regarded as independent prognostic factors for HCC;HCC patients with decreased Wnt5a or Ror2 protein expression had a poorer prognosis than those with elevated Wnt5a and Ror2 expression (P=0.016,P=0.007,respectively).CONCLUSION:Wnt5a and Ror2 may serve as tumor suppressor genes in the development of HCC,and may serve as clinicopathologic biomarkers for prognosis in HCC patients. | Ming Geng Yong-Cheng Cao Ying-Jian Chen Hui Jiang Li-Quan Bi Xiao-Hong Liu | 2012 | World Journal of Gastroenterology2012，18，12： | 12 |
| 4 | Stems and leaves of Aconitum carmichaelii Debx.as potential herbal resources for treating rheumatoid arthritis: Chemical analysis,toxicity and activity evaluation显示文摘According to folk usage of Aconitum carmichaelii Debx., the present study was designed to determine the feasibility of the stems and leaves of Aconitum carmichaelii Debx. as a new medicinal resource. Fourteen alkaloids in mother roots, fibrous roots, stems, and leaves of Aconitum carmichaelii Debx. were measured by HPLC-MS/MS. And multivariate analysis methods, such as clustering analysis and principal component analysis, were applied to analyze the difference among various parts. In addition, the acute toxicity, analgesia, and anti-inflammatory tests were carried out. The results suggested that the contents of alkaloids in mother roots and fibrous roots were approximate, but those of leaves and stems were different from mother roots and fibrous roots. The results of the acute toxicity testing demonstrated the toxicity of fibrous root was strongest, and mother roots were slightly less toxic than fibrous roots. The stems and leaves were far less toxic than mother and fibrous roots. In addition, the analgesia and inflammatory tests showed the effects of the various tissues had no difference each other. These results provided a basis for developing new complementary and alternative treatments for rheumatoid arthritis patients. Simultaneously, the approach may also turn wastes into treasure and promote the development of circular economy. | HE Ya-Nan OU Shui-Ping XIONG Xi PAN Yuan PEI Jin XU Run-Chun GENG Fu-Neng HAN Li ZHANG Ding-Kun YANG Ming | 2018 | Chinese Journal of Natural Medicines2018，16，9： | 10 |

| 6 | Preparation of CS-CMC Bipolar Membrane and its Application in Electro-generated FeO_4^(2-)显示文摘CS-CMC bipolar membrane was prepared and the cross-section photograph of CS-CMC BM was observed by SEM. FT-IR spectrum indicated that CS-CMC BM contained -N=CRH2+ and -COO- functional groups. The charge density of -N=CRH2+ in CS membrane was about 14.13 mmol/g and the charge density of -COO- in CMC membrane was about 9.01 mmol/g. The electrochemistry properties of CS-CMC BM were also studied. CS-CMC BM not only can effectively stop FeO4 from diffusing into the cathode chamber, but also plays an important role in the supply of OH- consumed during the electro-generated FeO42- process. | Yu Xi REN Zhen CHEN Ri Yao CHEN Xi ZHEN Ya Ming GENG | 2006 | Chinese Chemical Letters2006，17，11： | 5 |

| 8 | GOLM1 exacerbates CD8^(+)T cell suppression in hepatocellular carcinoma by promoting exosomal PD-L1 transport into tumor-associated macrophages显示文摘The immunosuppressive microenvironment plays an important role in tumor progression and immunotherapy responses.Golgi membrane protein 1(GOLM1)is correlated to hepatocellular carcinoma(HCC)progression and metastasis.However,little is known about the role of GOLM1 in regulating the immunosuppressive environment and its impact on immunotherapeutic efficacy in HCC.In this study,GOLM1 was positively correlated with infiltrating tumor-associated macrophages(TAMs)expressed high levels of programmed death-ligand 1(PD-L1)and CD8^(+)T cell suppression in HCC tissues.Both gain-and loss-of-function studies determined a close correlation between GOLM1 and immunosuppression.In the mechanism,GOLM1 promoted COP9 signalosome 5-mediated PD-L1 deubiquitination in HCC cells and increased the transport of PD-L1 into exosomes via suppression of Rab27b expression.Furthermore,co-culture with exosomes derived from HCC cells upregulated the expression of PD-L1 on macrophages.Zoledronic acid in combination with anti-PD-L1 therapy reduced PD-L1^(+)TAMs infiltration and alleviated CD8^(+)T cell suppression,resulting in tumor growth inhibition in the mouse HCC model.Together,our study unveils a mechanism by which GOLM1 induces CD8^(+)T cells suppression through promoting PD-L1 stabilization and transporting PD-L1 into TAMs with exosome dependent.Targeting PD-L1^(+)TAM could be a novel strategy to enhance the efficacy of anti-PD-L1 therapy in HCC. | Jinhong Chen Zhifei Lin Lu Liu Rui Zhang Yan Geng Minghao Fan Wenwei Zhu Ming Lu Lu Lu Huliang Jia Jubo Zhang Lun-Xiu Qin | 2021 | Signal Transduction and Targeted Therapy2021，6，12： | 5 |
| 9 | Effects of in-situ TiB_(2)particles on machinability and surface integrity in milling of TiB_(2)/2024 and TiB_(2)/7075 Al composites显示文摘In-situ ceramics particle reinforced aluminum matrix composites are favored in the aerospace industry due to excellent properties.However,the hard ceramic particles as the reinforcement phase bring challenges to machining.To study the effect of in-situ TiB_(2)particles on machinability and surface integrity of TiB_(2)/2024 composite and TiB_(2)/7075 composite,milling experiments were performed,and compared with conventional 2024 and 7075 aluminum alloys.In-situ TiB_(2)particles clustered at the grain boundaries and dispersed inside the matrix alloy grains hinder the dislocation movement of the matrix alloy.Therefore,the milling force and temperature of the composites are higher than those of the aluminum alloys due to the increase of the strength and the decrease of the plasticity.In the milling of composites,abrasive wear is the main wear form of carbide tools,due to the scratching of hard nano-TiB_(2)particles.The composites containing in-situ TiB_(2)particles have machining defects such as smearing,micro-scratches,micro-pits and tail on the machined surface.However,in-situ TiB_(2)particles impede the plastic deformation of the composites,which greatly reduces cutting edge marks on the machined surface.Therefore,under the same milling parameters,the surface roughness of TiB_(2)/2024 composite and TiB_(2)/7075 composite is much less than that of2024 and 7075 aluminum alloy respectively.Under the milling conditions of this experiment,the machined subsurface has no metamorphic layer,and the microhardness of the machined surface is almost the same as that of the material.Besides,compared with 2024 and 7075 aluminum alloy,machined surfaces of TiB_(2)/2024 composite and TiB_(2)/7075 composite both show tensile residual stress or low magnitude of compressive residual stress. | Jie CHEN Weiwei YU Zhenyu ZUO Yugang LI Dong CHEN Qinglong AN Jiwei GENG Ming CHEN Haowei WANG | 2021 | Chinese Journal of Aeronautics2021，34，6： | 5 |
| 10 | Straw return increases crop grain yields and K-use efficiency under a maize-rice cropping system显示文摘Straw return is an effective way to improve crop grain yield and potassium(K)use efficiency by increasing soil K content.However,the effects of straw return on soil K supplying capacity,replacement of K fertilizer,and K-use efficiency under maize(Zea mays L.)–rice(Oryza sativa L.)cropping systems are little studied.A two-year field experiment was conducted to determine the physiological determinants of K-use efficiency under straw return with four K fertilization rates.Sr33(straw returned plus 33%of K fertilizer applied)and Sr67(straw returned plus 67%of K fertilizer applied)increased annual crop yields by 1.5%and 3.2%and increased agronomic K-use efficiency by respectively 2.9 and 1.3-fold on average in the two years,compared with the conventional practice S0K100(no straw returned plus normal amounts of K fertilizer applied).The Sr33 and Sr67 treatments resulted in significantly greater equilibrium K concentration ratios(CR0 K)and specifically exchangeable K(KX)values according to quantity/intensity(Q/I)relationship analyses,indicating improvement of the potential soil K supply capacity.However,the Sr67 better maintained the soil exchangeable K level and K balance.The results suggested that K released from maize and rice straw can replace about half of chemical K fertilizer,depending on the available K content in maize–rice cropping system production. | Yuling Han Wei Ma Baoyuan Zhou Akram Salah Mingjian Geng Cougui Cao Ming Zhan Ming Zhao | 2021 | The Crop Journal2021，9，1： | 5 |
| 11 | Equations of state for aqueous solutions under mantle conditions显示文摘With unique physical and chemical properties, aqueous solutions in the mantle may play important roles for a number of geochemical and geodynamical processes. However, since experimental data available are very limited, people still know little about the aqueous solutions and their interactions with surrounding rocks and melts. From the perspective of thermodynamics, equation of state(EOS) is the key to push forward the modeling of aqueous solutions. Nevertheless, up to now accurate EOSs suitable for the mantle conditions are still in shortage. With discussions over several recognized EOSs, we summarize several ways to enhance the predictability of EOS: utilizing high quality data from molecular simulations, choosing functions with sound physical background, and improving the regression procedures for the empirical parameters. In the meantime, we find that the ion-bearing systems are still the focus of challenges in this area. New developments of experiments and computer simulations effectively deal with these challenges and in-depth understandings of aqueous solutions in the mantle are expected in the near future. | ZHANG ZhiGang ZHANG Chi GENG Ming | 2016 | Science China Earth Sciences2016，59，6： | 4 |
| 12 | The study on the mechanical properties of PU/MF double shell self-healing microcapsules显示文摘The self-healing microcapsules can be buried in the coating to improve the anticorrosive ability.In this paper,self-healing microcapsules of polyurea(PU)/melamine resin(MF)double shell were prepared by in-situ polymerization and interfacial polymerization with isocyanate as the core material.Scanning electron microscope was used to observe the microcapsule morphology.The structures of microcapsules prepared with different chain extenders were characterized by Fourier transform infrared spectroscopy.The micromanipulation system was used to loading–holding,loading–unloading and loading to rupture individual microcapsules,so as to explore the mechanical properties of microcapsules.The Young’s modulus corresponding to microcapsules was calculated by mathematical model fitting.The self-healing properties of microcapsule coating were characterized by optical microscope.The experimental results showed that the microcapsule shell prepared under optimized conditions had a complete morphology and good mechanical properties.The microcapsule was in the elastic deformation stage under small deformation,and the plastic deformation stage under large deformation.The Young’s modulus range of microcapsules was 9.29–14.51 MPa,and the corresponding Young’s modulus could be prepared by adjusting the process.The surface crack of the coating containing microcapsule could heal itself after48 h in a humid environment. | Guohao Du Jianfeng Hu Jianhui Zhou Guangwu Wang Shengli Guan Hailing Liu Man Geng Chuang Lv Yaoqiang Ming Jinqing Qu | 2020 | Chinese Journal of Chemical Engineering2020，28，5： | 4 |
| 13 | Selection and characterization of the novel anti-human PD-1 FV78 antibody from a targeted epitope mammalian cell-displayed antibody library显示文摘Currently,display-based methods are well established and widely used in antibody engineering for affinity maturation and structural stability improvement.We obtained a novel anti-human programmed death 1(PD-1)antibody using computer-aided design and a mammalian cell display technology platform.We used computer-aided modeling and distance geometry methods to predict and assign the key residues that contributed to the binding of human PD-L1 to PD-1.Then,we analyzed the sequence of nivolumab(an anti-human PD-1 antibody,referred to as MIL75 in the article)to determine the template for antibody design and library construction.We identified a series of potential substitutions on the obtained template and constructed a virtual epitope-targeted antibody library based on the physicochemical properties and each possible location of the assigned key residues.The virtual antibody libraries were displayed on the surface of mammalian cells as the antigen-binding fragments of full-length immunoglobulin G.Then,we used flow cytometry and sequencing approaches to sort and screen the candidates.Finally,we obtained a novel anti-human PD-1 antibody named FV78.FV78 competitively recognized the PD-1 epitopes that interacted with MIL75 and possessed an affinity comparable to MIL75.Our results implied that FV78 possessed equivalent bioactivity in vitro and in vivo compared with MIL75,which highlighted the probability and prospect of FV78 becoming a new potential antibody therapy. | Longlong Luo Shi Wang Xiaoling Lang Tingting Zhou Jing Geng Xinying Li Chunxia Qiao Jiannan Feng Beifen Shen Ming Lv Yan Li | 2018 | Cellular & Molecular Immunology2018，15，2： | 4 |
| 14 | HSP90 and SIRT3 expression in hepatocellular carcinoma and their effect on invasive capability of human hepatocellular carcinoma cells显示文摘Objective:To vexplore expression of HSP90,SIRT3 in liver cancer tissue and its effect on liver cancer cell invasion ability.Methods:Moderate expression of HSP90 in SMMC-7721,HepG2,LO2 and Hep-3B cell lines were screened,which was validated by RT-PCR.Overexpression of HSP90 cell line and lentivirus packaging HSP90-RNAi were established,which was validated by RT-PCR and western blot.The level of epithelial-mesenchymal transition(EMT)related gene was detected by western blot.The percentage of cancer stem cells was assayed by flow cytometry.Results:RT-PCR demonstrated the highest expression of HSP90mRNA in SMMC-7721 cells,the lowest expression of HSP90 mRNA in Hep3B and LO2 and the moderate expression of HSP90 mRNA in Hep-G2.Therefore,HepG2 was selected as a follow-up experiment cell lines.Compared with the blank control group,expression of HSP90in HSP overexpression group was increased obviously,and expression of HSP90 in HSP90shRNA group was significantly decreased,which indicated successful establishment of HSP overexpression and shRNA group.The apoptotic cell in hsp-siRNA group was higher than the blank control group,while the HSP overexpression group showed opposite results.Western blot results showed transfection HSP promoted cells EMT transformation,up-regulated the level of E-cadherin,and down-regulated the level of Vimentin;meanwhile,shRNA group showed opposite results.Conclusions:Carcinoma HepG2 cell transfeeted high expression of HSP can promote the transformation of EMT,improve the expression of Vimentin,reduce the expression of E-cadherin,and inhibit apoptosis of cancer stem cells,which improve the invasive ability of cancer of the liver cells.While hsp-siRNA group presents opposite results.In summary,the expression of HSP is closely related to the occurrence,development and invasion of cancer of the liver tissue. | Ming Gao Xiao-Ping Geng He-Ping Xiang | 2015 | Asian Pacific Journal of Tropical Medicine2015，8，4： | 4 |
| 15 | First experimental constraints on WIMP couplings in the effective field theory framework from CDEX显示文摘We present weakly interacting massive particles(WIMPs) search results performed using two approaches of effective field theory from the China Dark Matter Experiment(CDEX), based on the data from both CDEX-1B and CDEX-10 stages. In the nonrelativistic effective field theory approach, both time-integrated and annual modulation analyses were used to set new limits for the coupling of WIMP-nucleon effective operators at 90% confidence level(C.L.) and improve over the current bounds in the low mχregion. In the chiral effective field theory approach, data from CDEX-10 were used to set an upper limit on WIMP-pion coupling at 90% C.L. We for the first time extended the limit to the m_(χ)<6 GeV/c^(2) region. | Yi Wang Zhi Zeng Qian Yue LiTao Yang KeJun Kang YuanJing Li Mehment Agartioglu HaiPeng An JianPing Chang JingHan Chen YunHua Chen JianPing Cheng Cheng Yi Chiang WenHan Dai Zhi Deng ChangHao Fang XinPing Geng Hui Gong QiuJu Guo XuYuan Guo HongJian He Li He ShengMing He JinWei Hu TuChen Huang HanXiong Huang HaiTao Jia LiPing Jia Xi Jiang HauBin Li JianMin Li Jin Li MingXuan Li RenMingJie Li Xia Li YuLan Li Bin Liao FongKay Lin ShinTed Lin ShuKui Liu YanDong Liu Yu Liu YuanYuan Liu ZhongZhi Liu Hao Ma YuCai Mao QiYuan Nie JinHua Ning Hui Pan NingChun Qi Jie Ren XiChao Ruan ChangSong Shang Vivek Sharma Ze She Lakhwinder Singh Monoj Kumar Singh TianXi Sun ChangJian Tang WeiYou Tang Yang Tian GuangFu Wang Li Wang Qing Wang Yu Chen Wang YunXiang Wang Zhen Wang Henry Tsz-King Wong ShiYong Wu YuCheng Wu HaoYang Xing Yin Xu Tao Xue YuLu Yan Nan Yi ChunXu Yu HaiJun Yu JianFeng Yue Ming Zeng BingTao Zhang Lei Zhang FengShou Zhang ZhenYu Zhang KangKang Zhao MingGang Zhao JiFang Zhou ZuYing Zhou JingJun Zhu | 2021 | Science China(Physics,Mechanics & Astronomy)2021，64，8： | 3 |

| 17 | Effects of P addition on the microstructure and mechanical properties of Mg–5%Sn–1.25%Si alloy显示文摘The effects of Al-P addition on the microstructure and mechanical properties of as-cast Mg–5%Sn–1.25%Si magnesium alloy were investigated. The results show that the phases of the as-cast alloy are composed of α-Mg, Mg2 Sn, Mg2 Si, little P, and AlP. The Chinese character shape Mg2 Si phase changes into a granular morphology by P addition because AlP can act as a heterogeneous nucleation core for the Mg2 Si phase. When 0.225wt% of Al–3.5%P alloy is added, the mechanical properties of the Mg–5%Sn–1.25%Si alloy are greatly improved, and the tensile strength increases from 156 to 191 MPa, an increase of 22.4% compared to the alloy without P addition. When the amount of Al–3.5%P reaches 0.300wt%, a segregation phenomenon occurs in the granular Mg2 Si phase, and the tensile strength and hardness decrease though the elongation increases. | Hao-ran Geng Qing-lei Wang Peng Liu Ming Wu | 2014 | International Journal of Minerals,Metallurgy and Materials2014，21，3： | 3 |
| 18 | Numerical simulation of flow focusing pattern and morphological changes in two-phase flow inside nozzle显示文摘The flow focusing nozzle is a new type of nozzle that performs effective atomization of the discrete phase by means of high-speed motion of the continuous phase.The flow pattern and its morphological changes have a significant effect on the atomization, but the influence of different parameters on the morphological change of the flow pattern remains unclear.The flow focusing pattern and morphological changes in the two-phase flow inside the nozzle were simulated numerically, based on the volume of fluid method.The results demonstrate that the ratio of the nozzle-to-capillary distance and capillary diameter, the gas–liquid velocity ratio, and capillary diameter have significant effects on the flow pattern.When the ratio of the nozzle-to-capillary distance H and capillary diameter D increases, or the capillary diameter D increases, the flow pattern tends to transform into a laminar form; however, when the gas–liquid velocity ratio V increases, the flow pattern tends to transform into a turbulence form.Furthermore, we define the cone-shaped expansion rate, cone-shaped focusing rate,and cone angle in order to study the morphological changes in the cone shape inside the nozzle.The results indicate that the morphological change of the cone shape and flow pattern transformation is interrelated.When the cone shape tends to be unstable, the flow pattern changes towards flow blurring, whereas, a stable cone indicates that the flow tends to exhibit a droplet pattern. | Jin Zhao Zhi Ning Ming Lü Geng Wang | 2019 | Chinese Journal of Chemical Engineering2019，27，1： | 2 |
