| 2 | Generation of B Cell-Deficient Pigs by Highly Efficient CRISPR/Cas9-Mediated Gene Targeting显示文摘Generating B cell-deficient mutant is the first step to produce human antibody repertoires in large animal models. In this study, we applied the clustered regularly interspaced short palindromic repeat(CRISPR)/CRISPR-associated(Cas) system to target the JHregion of the pig Ig M heavy chain gene which is crucial for B cell development and differentiation. Transfection of Ig M-targeting Cas9 plasmid in primary porcine fetal fibroblasts(PFFs) enabled inducing gene knock out(KO) in up to 53.3% of colonies analyzed, a quarter of which harbored biallelic modification, which was much higher than that of the traditional homologous recombination(HR). With the aid of somatic cell nuclear transfer(SCNT) technology, three piglets with the biallelic Ig M heavy chain gene mutation were produced. The piglets showed no antibody-producing B cells which indicated that the biallelic mutation of the Ig M heavy chain gene effectively knocked out the function of the Ig M and resulted in a B cell-deficient phenotype. Our study suggests that the CRISPR/Cas9 system combined with SCNT technology is an efficient genome-editing approach in pigs. | Fengjiao Chen Ying Wang Yilin Yuan Wei Zhang Zijian Ren Yong Jin Xiaorui Liu Qiang Xiong Qin Chen Manling Zhang Xiaokang Li Lihua Zhao Ze Li Zhaoqiang Wu Yanfei Zhang Feifei Hu Juan Huang Rongfeng Li Yifan Dai | 2015 | Journal of Genetics and Genomics2015，42，8： | 15 |

| 4 | Fabrication and properties of foam geopolymer using circulating fluidized bed combustion fly ash显示文摘In recent years,circulating fluidized bed combustion fly ash(CFA) is used as a raw material for geopolymer synthesis.Hydrogen peroxide was employed as a foaming agent to prepare CFA-based foam geopolymer.The particle distribution,mineral composition,and chemical composition of CFA were examined firstly.Geopolymerization products were characterized by mechanical testing,scanning electron microscopy(SEM),X-ray diffraction(XRD),and X-ray fluorescence(XRF).The CFA-based foam geopolymer was successfully fabricated with different contents of hydrogen peroxide and exhibited uncompleted alkali reaction and reasonable strength with relative low atomic ratios of Si/Al and Si/Na.Type-C CFA in this research could be recycled as an alternative source material for geopolymer production. | Ze Liu Ning-ning Shao Dong-min Wang Jun-feng Qin Tian-yong Huang Wei Song Mu-xi Lin Jin-sha Yuan Zhen Wang | 2014 | International Journal of Minerals,Metallurgy and Materials2014，21，1： | 11 |
| 5 | The anti-inflammatory effects of asiatic acid in lipopolysaccharide-stimulated human corneal epithelial cells显示文摘AIM: To investigate the anti-inflammatory effects of asiatic acid(AA) on lipopolysaccharide(LPS)-induced inflammatory response in human corneal epithelial cells(HCECs).METHODS: Cell viability was measured using a cell counting kit-8(CCK-8) assay.Quantitative real-time polymerase chain reaction(qR T-PCR) was used to determine the mR NA expression of interleukin-8(IL-8),interleukin-6(IL-6),interleukin-1β(IL-1β),tumor necrosis factor-alpha(TNF-α),and transforming growth factor-β(TGF-β) in HCECs.Intracellular reactive oxygen species(ROS) was measured using the ROS assay kit.Glutathione(GSH) concentration was measured using the total GSH assay kit.Akt1 and Akt phosphorylation(p-Akt1) levels were measured by Western blotting and immunofluorescence.RESULTS: AA induced toxicity at high concentrations and significantly stimulated the proliferation of HCECs at concentrations of 20 μmol/L for 1h.LPS at concentrations of 300 ng/mL for 1h significantly stimulated the mR NA expression of IL-8,IL-6,IL-1β,TNF-α,and TGF-β in HCECs,while the stimulation effects were significantly inhibited by AA(20 μmol/L).In addition,AA was found to decrease the content of ROS,increase GSH generation,and also inhibit LPS-induced p-Akt in HCECs.CONCLUSION: AA decreases the generation of inflammatory factors IL-8,IL-6,IL-1β,TNF-α,and TGF-β in LPSstimulated HCECs.AA significantly inhibites the intracellular concentrations of ROS and increases GSH generation.AA also inhibites LPS-induced p-Akt in HCECs.These findings reveal that AA has anti-inflammation effects in LPS-stimulated HCECs. | Hao Chen Xiao-Min Hua Bai-Chen Ze Bin Wang Li Wei | 2017 | International Journal of Ophthalmology(English edition)2017，10，2： | 9 |
| 6 | Impedance Modeling and Stability Analysis of PV Grid-connected Inverter Systems Considering Frequency Coupling显示文摘Impedance analysis is an effective method to analyze the oscillation issue associated with grid-connected photovoltaic systems.However,the existing impedance modeling of a gridconnected photovoltaic inverter usually only considers the effect of a single perturbation frequency,ignoring the coupling frequency response between the internal control loops of a grid-connected inverter,which severely affects the accuracy of the stability analysis.Hence,a method of impedance modeling and stability analysis for grid-connected photovoltaic inverters considering cross-coupling frequency is proposed in this paper.First,the generation mechanism of frequency coupling in gridconnected photovoltaic inverters,and the relationship between the coupling frequency and perturbation frequency are analyzed.Secondly,a sequence impedance model of grid-connected photovoltaic systems considering the coupling frequency is established by using the harmonic linearization method.The impact of DC bus voltage control strategy on frequency coupling characteristics of a grid-connected photovoltaic system is evaluated,and the impact of a coupling frequency term on system stability is quantitatively analyzed.Finally,the advantages of the proposed method are verified by several simulations.The results show that the proposed impedance model can accurately predict the potential resonance points of the system,and the coupling frequency characteristics will become much stronger with smaller DC bus capacitance or larger bandwidth of the DC bus controller. | Shaojian Song Ze Wei Yuzhang Lin Bin Liu Hui Liu | 2020 | CSEE Journal of Power and Energy Systems2020，6，2： | 8 |
| 7 | Isolation and Analysis of α-Gliadin Gene Coding Sequences from Triticum durum显示文摘Three coding sequences of gliadins genes, designed as Gli2_Du1, Gli2_Du2 and Gli2_Du3, were isolated from thegenomic DNA of Triticum durum accessions CItr5083. Gli2_Du1 and Gli2_Du2 contain 945 and 864 bp, encoding themature proteins with 314 and 287 amino acid residues, respectively. Gli2_Du3 is recognized as a pseudogene due to thestop codon occurring in the coding region. The pseudogenes, commonly occurring in gliadins family, are attributed to thesingle base change C → T. The amino acid sequences deduced from these gene sequences were characterized with thetypical structure of α-gliadin proteins, including the toxic sequences (PSQQQP). The peptide fraction PF(Y)PP(Q) isthought to be an extra unit of repetitive domain, slightly diverging from the previous report. Six cysteine residues wereobserved within two unique domains. Phylogenetic analysis showed Gli2_Du2 and Gli2_Du3 were closely related to thegenes on chromosome 6A, whereas Gli2_Du1 seems to be more homologous with the genes on chromosome 6B. | WANG Han-yan WEI Yu-ming ZE Hong-yan ZHENG You-liang | 2007 | Agricultural Sciences in China2007，6，1： | 7 |
| 8 | Hydrogen-rich saline protects against ultraviolet B radiation injury in rats显示文摘Exposure of skin to solar ultraviolet(UV) radiation induces photo-damage.Ultraviolet B(UVB) is the major component of UV radiation which induces the production of reactive oxygen species(ROS) and plays an impor-tant role in photo-damage.Hydrogen gas reduces ROS and alleviates inflammation.In this study,we sought to demonstrate that hydrogen-rich saline has the effect on skin injuries caused by UVB radiation.UVB radiation was irradiated on female C57BL/6 rats to induce skin injury.Hydrogen-rich saline and nitrogen-rich saline were ad-ministered to rats by intraperitoneal injection.Skin damage was detected by microscope after injury.UVB radia-tion had a significant affection in tumor necrosis factor alpha,interleukin(IL)-1β and IL-6 levels,tissue superox-ide dismutase,malondialdehyde and nitric oxide activity.Hydrogen-rich saline had a protective effect by altering the levels of these markers and relieved morphological skin injury.Hydrogen-rich saline protected against UVB radiation injury,possibly by reducing inflammation and oxidative stress. | Ze Guo Bingrong Zhou Wei Li Xuejun Sun Dan Luo | 2012 | The Journal of Biomedical Research2012，26，5： | 6 |
| 9 | Phylogeny and evolutionary history of the silkworm显示文摘The silkworm,Bombyx mori,played an important role in the old Silk Road that connected ancient Asia and Europe.However,to date,there have been few studies of the origins and domestication of this species using molecular methods.In this study,DNA sequences of mitochondrial and nuclear loci were used to infer the phylogeny and evolutionary history of the domesticated silkworm and its relatives.All of the phylogenetic analyses indicated a close relationship between the domesticated silkworm and the Chinese wild silkworm.Domestication was estimated to have occurred about 4100 years ago(ya),and the radiation of the different geographic strains of B.mori about 2000 ya.The Chinese wild silkworm and the Japanese wild silkworm split about 23600 ya.These estimates are in good agreement with the fossil evidence and historical records.In addition,we show that the domesticated silkworm experienced a population expansion around 1000 ya.The divergence times and the population dynamics of silkworms presented in this study will be useful for studies of lepidopteran phylogenetics,in the genetic analysis of domestic animals,and for understanding the spread of human civilizations. | SUN Wei YU HongSong SHEN YiHong BANNO Yutaka XIANG ZhongHuai ZHANG Ze | 2012 | Science China(Life Sciences)2012，55，6： | 6 |

The protocol was formulated under the direct leadership of the National Administration of Traditional Chinese Medicine, based on the experience of a panel of experts, supported by evidence from fever clinics and from the outcomes of emergency(EM) observation rooms and inpatients throughout China(especially in Wuhan, Hubei Province) in combination with the latest scientific research results and data. The present interpretation of the TCM protocol is based on an overall understanding of the revised content, and aims to guide and standardize its clinical application to provide a reference for clinicians. | Song Ping Zhao Linhua Li Xiuyang Su Jiansen Jiang Zhaoyuan Song Bin Liu Wenke Tang Shuang Lei Ye Ding Qiyou Yang Ze Lin Jiaran Wei Yu Tong Xiaolin | 2020 | Journal of Traditional Chinese Medicine2020，40，3： | 5 |
| 11 | Spatio-temporal variation in rock exhumation linked to large-scale shear zones in the southeastern Tibetan Plateau显示文摘Crustal-scale shear zones are believed to have played an important role in the tectonic and landscape evolution of orogens. However, the variation of long-term rock exhumation between the interior of shear zones and adjacent regions has not been documented in detail. In this study, we obtained new zircon U-Pb, biotite ^(40)Ar/^(39)Ar, zircon and apatite(U-Th)/He data, and conducted inverse thermal history modeling from two age-elevation profiles(the Pianma and Tu'er profiles) in the southeastern Tibetan Plateau. Our goal is to constrain the exhumation history of the Gaoligong and Chongshan shear zones and adjacent regions, so as to explore the effect of the shear zones on exhumation and their thermal effect on cooling that should not be ignored. Our results suggest that during the interval of 18–11 Ma the exhumation rates of rocks within the Gaoligong shear zone are anomalously high compared with those outside of. The rapid cooling during 18–11 Ma appears to be restricted to the shear zone, likely due to localized thermal effects of shearing and exhumation. After 11 Ma, both the areas within and outside of the shear zones experienced a similar two-stage exhumation history: slower cooling until the early Pliocene, and then a rapid increase in cooling rate since the early Pliocene. Our results indicate a synchronized exhumation but with spatially varied exhumation rates. Our study also highlights the important role of large-scale shear zones in exposing rocks, and thus the importance of the structural context when interpreting thermochronological data in the southeastern margin of the Tibetan Plateau. | Yukui GE Jing LIU-ZENG Jinyu ZHANG Wei WANG Yuntao TIAN Matthew FOX Lingsen ZENG Xiaoming SHEN Heng WANG Ze SU Kejia XIE | 2020 | Science China Earth Sciences2020，63，4： | 5 |
| 12 | Samarium doped apatite-type orange-red emitting phosphor Ca5(PO4)2SiO4 with satisfactory thermal properties for n-UV w-LEDs显示文摘A novel single-phase Sm^3+activated Ca5(PO4)2SiO4 phosphor was successfully fabricated via a conventional solid-state method,which can be e fficie ntly excited by near ultraviolet(n-UV)light-emitting chips.The crystal structure and luminescence properties were characterized and analyzed systematically by using relevant instruments.The Ca5(PO4)2SiO4:Sm^3+phosphor shows an orange-red emission peaking at600 nm under the excitation of 403 nm and the optimal doping concentration of Sm^3+is determined to be 0.08,The critical distance of Ca5(PO4)2SiO4:0.08 Sm^3+is calculated to be 1.849 nm and concentration quenching mechanism of the Sm^3+in Ca5(PO4)2SiO4 host is ascribed to energy transfer between nearestneighbor activators.The decay time of Ca5(PO4)2 SiO4:0,08 Sm^3+is determined to be 1.1957 ms.In addition,the effect of temperature on the emission intensity was also studied,72.4%of the initial intensity is still preserved at 250℃,better thermal stability compared to commercial phosphor YAG:Ce^3+indicates that Ca5(PO4)2SiO4:0.08 Sm^3+has excellent thermal stability and active energy is deduced to be 0.130 eV.All the results demonstrate that orange-red emitting Ca5(PO4)2SiO4:0.08 Sm3+phosphor exhibits good luminescent properties.Owing to the excellent thermal quenching luminescence property,Ca5(PO4)2SiO4:0.08 Sm^3+phosphor can be applied in n-UV white light emitting diodes and serve as the warm part of white light. | Ze Zhang Jialiang Niu Wei Zhou Dingdian Xu Huanhuan Du | 2019 | Journal of Rare Earths2019，37，9： | 5 |
| 13 | Association between single nucleotide polymorphisms on chromosome 17q and the risk of prostate cancer in a Chinese population显示文摘In European populations,7 single nucleotide polymorphisms(SNPs) on chromosome 17q,3 SNPs on 17q12,and 4 SNPs on 17q24.3 were recently identified to be closely related to the risk of prostate cancer by a genome-wide association study.In Japanese populations,the correlation between 2 SNPs on 17q and the risk of prostate cancer and tumor aggressiveness was also confirmed by a large-scale experiment.However,whether 17q is associated with prostate cancer and its clinical manifestations in Chinese populations is still unknown.Therefore,we conducted a case-control study in a northern Chinese population and tested 2 SNPs,rs4430796 and rs1859962,on 17q in 124 prostate cancer patients and 111 controls using polymerase chain reaction-high resolution melting curve(PCR-HRM) combined with sequencing.We analyzed the association of the 2 SNPs with the risk of prostate cancer as well as patients' lifestyles,onset ages,Gleason scores,PSA levels,and pathologic stages.We found a significant difference in the G allele of SNP rs1859962(P = 0.035,OR = 1.51,95% CI = 1.03-2.21) but not in the rs4430796 genotype frequency or allele frequency distribution between prostate cancer patients and the controls(P > 0.05).Neither of the SNPs was significantly associated with the onset age,Gleason score,PSA level,pathologic stage,or other clinical indicators of patients with prostate cancer(P > 0.05).Our results show that polymorphism of the G allele of SNP rs1859962 is associated with the risk of prostate cancer in a Chinese population. | Chang-Hu Zhou Jian-Ye Wang Su-Yan Cao Xiao-Hong Shi Yao-Guang Zhang Ming Liu Xin wang Jin Huang Yi-Ge Yang Dong Wei Ze Yang | 2011 | Chinese Journal of Cancer2011，30，10： | 4 |

| 19 | Ecological rebuilding and land reclamation in surface mines in Shanxi Province, China显示文摘It is well known that the mining industry produces a large amount of derelict land, and causes pollution of water loss and soil erosion as well as other environmental damage in China. As land is under pressure in China, it is now policy to restore or reclaim land despoiled by mining, the aim being to develop sustainable and healthy arable land ecosystems. This paper outlines the principles and approaches of ecological restoration, which have been adopted in Shanxi Province with reference to three typical surface mines. In the research, the principles of ecological engineering and ecological succession are considered as the critical theories of ecological restoration in mine degraded land. Meanwhile, the paper made a comparative research on main links of ecological rebuilding in three surface mines in Shanxi Province, which include new land construction, treatment of toxic substances, control of soil erosion, fertility management, irrigation, ecological planning and the establishment of legislation systems. As the research demonstrated, for successful restoration, new land construction is the fundamental framework, but it must be integrated with ecological engineering including ecological planning, the control of soil erosion and vegetation establishment and ecosystem creation in order to optimise land productivity and soil fertility. In addition, the establishment of the legislation systems and organization of administration are also indispensable aspects of ecological rebuilding in mined land. | MIAO Ze wei 1, BAI Zhong ke 2, GAO Lin 1 (1.
