| 1 | Cryopreservation of mammalian oocytes and embryos: current problems and future perspectives显示文摘Cryopreservation techniques for mammalian oocytes and embryos have rapidly progressed during the past two decades,emphasizing their importance in various assisted reproductive technologies.Pregnancies and live births resulting from cryopreserved oocytes and embryos of several species including humans have provided proof of principle and led to the adoption of cryopreservation as an integral part of clinical in vitro fertilization.Considerable progress has been achieved in the development and application of the cryopreservation of mammalian oocytes and embryos,including preservation of the reproductive potential of patients who may become infertile,establishment of cryopreserved oocyte banks,and transport of oocytes and embryos internationally.However,the success rates are still far lower than those obtained with fresh oocytes and embryos,and there are still obstacles that need to be overcome.In this review,we address the major obstacles in the development of effective cryopreservation techniques.Such knowledge may help to eliminate these hurdles by revealing which aspects need improvement.Furthermore,this information may encourage further research by cryobiologists and increase the practical use of cryopreservation as a major part of assisted reproductive technologies for both humans and animal species. | MOUSSA Mahmoud SHU Juan ZHANG XueHong ZENG FanYi | 2014 | Science China(Life Sciences)2014，57，9： | 18 |
| 2 | Distinct element method analysis and field experiment of soil resistance applied on the subsoiler显示文摘Since the design of the subsoiler is a complex work,the interaction between the subsoiler and soil was investigated by using Distinct Element Method(DEM)in this study.Based on the traditional discrete element theory,the 3D model of soil particles and the subsoiler were established after considering the liquid bridge force between soil particles.The operating resistance curves of the subsoiler were achieved after the DEM simulation at a speed of 1 m/s,and three depths of 180 mm,220 mm and 260 mm,respectively.The simulation curves agreed well with the field experimental results based on relative errors of 2.96%,14.95%and 7.15%,respectively,at three depths.All these data proved that it was feasible and favorable to analyze the performance of the subsoiler by using the DEM and it is of important significance for studying and further optimizing the structure of the subsoiler. | Li Bo Liu Fanyi Mu Junying Chen Jun Han Wenting | 2014 | International Journal of Agricultural and Biological Engineering2014，7，1： | 9 |

| 4 | Modeling of flexible wheat straw by discrete element method and its parameter calibration显示文摘To simulate the bending behavior of wheat straw,a flexible straw model was developed based on the Hertz-Mindlin with bonding model using discrete element method.The proposed model was constructed by bonding straw units(filled by multi-spherical method)through parallel bonding keys.By means of a three-point bending test,single-factor sensitivity analysis and calibration of bonding parameters were performed.Results showed that elastic modulus of the flexible straw enhanced with the increase of bonded disk radius,normal stiffness per unit area and shear stiffness per unit area.The three bonding parameters were respectively calibrated to be 2.11 mm,9.48×10^(9)N/m^(3)and 4.67×10^(9)N/m^(3) by solving the regression equation developed from Box-Behnken design.The simulated elastic modulus(in terms of those three calibrated parameters)exhibited 4.20%difference with the measured one.It proved that the flexible straw could accurately demonstrate bending property of the wheat straw.This would not only help to improve accuracy in simulating wheat straw,but also provide references for flexible straw modeling and parameters calibration of other crops. | Fanyi Liu Jian Zhang Jun Chen | 2018 | International Journal of Agricultural and Biological Engineering2018，11，3： | 8 |
| 5 | Effects of donor cells on in vitro development of cloned bovine embryos显示文摘The donor cells from different individuals and with different foreign genes introduced were investigated to determine their effects on the efficiency of somatic cell nuclear transfer (SCNT). The bovine ear fibroblast from different individuals was isolated, cultured, and then transfected with foreign genes to establish the stable cell lines, which were used as donor cells for nuclear transfer. The oocytes were obtained through ovum pick up operation. After in vitro maturation, the M II phase oocytes were selected as receptors for nuclear transfer. The reconstructed embryos were cultured in vitro and observed at 2 h, 48 h, and 7 days after transfer to assess the rate of fusion using cleaved and blastocyst as the parameters of SCNT efficiency. The donor cells from different individuals (04036, 06081, 06088, and 06129) had no obvious effect on the fusion and cleaved rate, whereas there was significant difference in the blastocyst rate (P<0.05), and the rate was 62.3%, 37.0%, 35.1%, and 15.6%, respectively. There was no significant difference among the rate of fusion, cleaved and blastocyst in donor cells with different foreign genes (P>0.05). It was concluded that the genetic background of the donor cells could affect the effi- ciency of SCNT, while the introduction of foreign genes into the donor cells had no obvious effect on the efficiency. This study provides useful information for the SCNT and would benefit in promoting the efficiency. | Jing Fu Pengfei Guan Leiwen Zhao Hua Li Shuzhen Huang Fanyi Zeng Yitao Zeng | 2008 | Journal of Genetics and Genomics2008，35，5： | 6 |
| 6 | Determination of the draft force for different subsoiler points using discrete element method显示文摘Generally,a subsoiler is comprised of a shank and a point.The point shape has a significant effect on the draft force of a subsoiler.In this study,the draft force of subsoilers with four different points were compared under the speed of 0.8 m/s and the depth of 350 mm in the soil bin.Discrete Element Method(DEM)was applied in simulating the working process of the subsoiler.The stiffness of soil particles used in DEM was calibrated by comparing the simulated draft force of a standard arc-shaped subsoiler with the experiment.The calibrated soil particle stiffness was 1.1×104 N/m.The validated model was then used to compare the draft force of subsoilers with four different points under the same condition in the test.Results showed that different points would cause different draft forces.The subsoiler with short chisel point caused the smallest draft force(2885 N)while the point with short face and wings had the largest force(4474 N).The relative errors of the simulated results were less than 4%,which proved that DEM was an effective way for predicting the draft force of subsilers.The velocity field and contact force filed could show the movement of soil around the subsoiler. | Li Bo Xia Rui Liu Fanyi Chen Jun Han Wenting Han Bing | 2016 | International Journal of Agricultural and Biological Engineering2016，9，3： | 5 |
| 7 | Systematic review of risk factors for progressive ischemic stroke显示文摘OBJECTIVE: To determine the risk factors for progressive ischemic stroke, and to prevent onset and make a prognosis of disease, the present study systemically evaluated 19 cohort studies and 10 case-controlled studies of progressive ischemic stroke. SEARCH STRATEGY: A computer-based, online, literature search of PubMed (1966/2007), China Biological Medicine Database (CBM-disc, 1979/2007) and CNKI (www.cnki.net, 1979/2007) was performed to screen for related studies. DATA SELECTION: Cohort or case-controlled studies that focused on risk factors of progressive ischemic stroke were selected for review. Two reviewers independently extracted data and as-sessed study quality according to Cochrane Collaboration guidelines. Statistical analysis was per-formed using RevMan software. MAIN OUTCOME MEASUREMENT: Risk factors for progressive ischemic stroke. RESULTS: Using the inclusion criteria, 29/781 studies published in English and Chinese were ini-tially reviewed, including 19 cohort studies and 10 case-control studies. Despite variations in de-termination of progressive ischemic stroke and the intervals between 2 evaluations, all studies de-scribed the diagnostic criteria for progressive ischemic stroke. Logistic analysis was employed in 20 of the studies. Meta-analysis of primary data in the related studies determined that the following factors that significantly correlated with progressive ischemic stroke: fever [risk ratio (RR) = 2.26, 95% confidence interval (CI): 1.20–4.26, P = 0.01; odds ratio (OR) = 2.85, 95% CI: 1.64–4.98, P < 0.01)]; diabetes (RR = 1.38, 95% CI: 1.18–1.61, P < 0.01; OR = 2.48, 95% CI: 1.93–3.19, P < 0.01); coronary heart disease (RR = 1.22, 95% CI: 1.08–1.38, P < 0.01); neuroimaging transformation (RR = 1.55, 95%CI: 1.34–1.80, P < 0.01; OR = 2.29, 95% CI: 1.47–3.58, P < 0.01); and hypergly-cemia (RR = 2.62, 95% CI: 1.86–3.68, P < 0.01; OR = 3.49, 95% CI: 1.92–6.35, P < 0.01). CONCLUSION: Fever, diabetes, coronary heart disease, neuroimaging transformation, and hyper-glycemia are important risk factors for progressive ischemic stroke. Interventions for these risk fac-tors could effectively prevent occurrence of progressive ischemic stroke. | Weimin Yang Fanyi Kong Ming Liu Zilong Hao | 2011 | Neural Regeneration Research2011，6，5： | 5 |
| 8 | Integration-free Methods for Generating Induced Pluripotent Stem Cells显示文摘Induced pluripotent stem(iPS)cells can be generated from mouse or human fbroblasts by exogenous expression of four factors,Oct4,Sox2,Klf4 and c-Myc,and hold great potential for transplantation therapies and regenerative medicine.However,use of retroviral vectors during iPS cell generation has limited the technique’s clinical application due to the potential risks resulting from genome integration of transgenes,including insertional mutations and altered differentiation potentials of the target cells,which may lead to pathologies such as tumorigenesis.Here we review recent progress in generating safer transgene-free or integration-free iPS cells,including the use of non-integrating vectors,excision of vectors after integration,DNA-free delivery of factors and chemical induction of pluripotency. | Yi-ye Zhou Fanyi Zeng | 2013 | Genomics, Proteomics & Bioinformatics2013，11，5： | 3 |

| 14 | Amelioration of β^(654)-thalassemia in mouse model with the knockdown of aberrantly spliced β-globin mRNA显示文摘Large amounts of aberrantly spliced mRNA from the β654 allele was present in erythroid cells, which might impair the erythropoiesis. A therapeutic strategy for β-thalassemia was explored by knocking down the aberrantly spliced mRNA of β-globin. Lentiviral vector with siRNA fragment targets on the specific portion of β654-globin aberrantly spliced pre-mRNA was constructed. In HeLa β654 cells, the siRNA vector could reduce approximately 60% of aberrantly spliced mRNA, which was assessed by RT-PCR and qRT-PCR. Furthermore, a disease model of β654 thalassemia mice with lentiviral-mediated siRNA was produced by subzonal injection (named Hβi-Hbbth-4/Hbb+ transgenic mice). Our results showed that the hemotological parameters were improved in Hβi-Hbbth-4/Hbb+ transgenic mice. This study provides a potential way for β654-thalassemia therapy by knocking down the aberrantly spliced β-globin mRNA, whilst supporting that the aberrantly spliced β-globin mRNA may aggravate the disease. | Shuyang Xie Wei Li Zhaorui Ren Jingzhi Zhang Xinbin Guo Shu Wang Shuzhen Huang Fanyi Zeng Yi-Tao Zeng | 2008 | Journal of Genetics and Genomics2008，35，10： | 1 |

| 19 | Few-layered MoS_(2)anchored on 2D porous C_(3)N_(4)nanosheets for Ptfree photocatalytic hydrogen evolution显示文摘The Pt-free photocatalytic hydrogen evolution(PHE)has been the focus in the photocatalytic field.The catalytic system with the large accessible surface and good mass-transfer ability,as well as the intimate combination of co-catalyst with semiconductor is promising for the promotion of the application.Here,we have reported the design of the two-dimensional(2D)porous C_(3)N_(4)nanosheets(PCN NS)intimately combined with few-layered MoS_(2)for the high-effective Pt-free PHE.The PCN NS were synthesized based on peeling the melamine–cyanuric acid precursor(MC precursor)by the triphenylphosphine(TP)molecular followed by the calcination,mainly due to the matched size of the(100)plane distance of the precursor(0.8 nm)and the height of TP molecular.The porous structure is favorable for the mass-transfer and the 2D structure having large accessible surface,both of which are positive to promote the photocatalytic ability.The few-layered MoS_(2)are grown on PCN to give 2D MoS_(2)/PCN composites based on anchoring phosphomolybdic acid(PMo_(12))cluster on polyetherimide(PEI)-modified PCN followed by the vulcanization.The few-layered MoS_(2)have abundant edge active sites,and its intimate combination with porous PCN NS is favorable for the faster transfer and separation of the electrons.The characterization together with the advantage of 2D porous structure can largely promote the photocatalytic ability.The MoS_(2)/PCN showed good PHE activity with the high hydrogen production activity of 4,270.8μmol·h^(−1)·g^(−1)under the simulated sunlight condition(AM1.5),which was 7.9 times of the corresponding MoS_(2)/bulk C_(3)N_(4)and 12.7 times of the 1 wt.%Pt/bulk C_(3)N_(4).The study is potentially meaningful for the synthesis of PCN-based catalytic systems. | Nan Wang Dongxu Wang Aiping Wu Siyu Wang Zhihui Li Chengxu Jin Youming Dong Fanyi Kong Chungui Tian Honggang Fu | 2023 | Nano Research2023，16，2： | 1 |
