| 3 | The resurgent landscape of xenotransplantation of pig organs in nonhuman primates显示文摘Organ shortage is a major bottleneck in allotransplantation and causes many wait-listed patients to die or become too sick for transplantation.Genetically engineered pigs have been discussed as a potential alternative to allogeneic donor organs.Although xenotransplantation of pig-derived organs in nonhuman primates(NHPs)has shown sequential advances in recent years,there are still underlying problems that need to be completely addressed before clinical applications,including(i)acute humoral xenograft rejection;(ii)acute cellular rejection;(iii)dysregulation of coagulation and inflammation;(iv)physiological incompatibility;and(v)cross-species infection.Moreover,various genetic modifications to the pig donor need to be fully characterized,with the aim of identifying the ideal transgene combination for upcoming clinical trials.In addition,suitable pretransplant screening methods need to be confirmed for optimal donor-recipient matching,ensuring a good outcome from xenotransplantation.Herein,we summarize the understanding of organ xenotransplantation in pigs-to-NHPs and highlight the current status and recent progress in extending the survival time of pig xenografts and recipients.We also discuss practical strategies for overcoming the obstacles to xenotransplantation mentioned above to further advance transplantation of pig organs in the clinic. | Xuan Zhang Quancheng Wang Jingjun Zhao Xiao Li Wei Peng Zhaoxu Yang Zhibin Lin Long Yang Rui Ding Kaishan Tao Kefeng Dou | 2021 | Science China(Life Sciences)2021，64，5： | 10 |
| 4 | Application of open-pit and underground mining technology for residual coal of end slopes显示文摘Given the conditions of residual coal from the boundary of a flat dipping open-pit mine,which uses strip areas mining and inner dumping with slope-covering,we propose an open-pit and underground integrated mining technology for residual coal of end slopes.In the proposal a conveyance road and ventilation conveyance near the slope are built,corresponding to the pit mining area and the surface coal mine dump,as well as an interval haulage tunnel and air-inlet tunnel.The outcome shows that such mining method may reduce the effect to slope stability from underground mining,it does not affect the dumping advance and has a high recovery rate of residual coal resources.The working face is timbered by single hydraulic props,transported by a scraper conveyor and supported by coal walls.This method of mining is one of layered top coal caving,with high resource recovery,low production cost where positive economic benefit can be realized. | CHE, Zhaoxue YANG, Hong | 2010 | Mining Science and Technology2010，20，2： | 9 |
| 5 | Long-term outcomes in patients with ypT0 rectal cancer after neoadjuvant chemoradiotherapy and curative resection显示文摘Objective: For patients with locally advanced rectal cancer treated with neoadjuvant chemoradiotherapy(NCRT), significant pathological response of the primary tumor has been proposed to identify candidates for organ preservation. However, this does not address metastatic lymph nodes in the mesorectum. The aim of this study was to assess the incidence of lymph node metastases in ypT0 patients treated with NCRT and curative resection and to explore risk factors associated with survival.Methods: This was a retrospective study of patients with ypT0 rectal cancer after NCRT and curative resection at a tertiary care center in China from 2005 to 2014.Results: A total of 60(18.6%) patients who underwent surgery after NCRT and achieved ypT0 were enrolled in this study; one patient was excluded owing to lack of follow-up. Of these 59 patients, lymph node metastases were found in the mesorectum(ypT0N+) in eight(13.6%) patients. After a median follow-up of 52 months, 5-year recurrence-free survival(82.7% vs. 62.5%, P=0.014) and overall survival(OS)(90.9% vs. 70.0%, P=0.032) were much higher in ypN0 than yp N+ patients. Multivariate analyses showed that ypN+ status(P=0.009) and perioperative blood transfusion(BT)(P=0.001) were significantly independent risk factors associated with recurrence; however, no factor was correlated with 5-year OS.Conclusions: Patients with ypT0N0 rectal cancer can achieve excellent long-term outcomes; however, positive lymph nodes or tumor deposits can still be found in 13.6% of ypT0 patients. Nodal positivity in the mesorectum and perioperative BT are independent risk factors for recurrence. | Zhao Lu Pu Cheng Fu Yang Zhaoxu Zheng Xishan Wang | 2018 | Chinese Journal of Cancer Research2018，30，2： | 8 |
| 6 | Mineralogical and micromorphological characteristics of Si-Fe-Mn oxyhydroxides from the PACMANUS hydrothermal field, Eastern Manus Basin显示文摘The mineralogical and micromorphological characteristics of Si-Fe-Mn oxyhydroxides from the dacite-hosted PACMANUS hydrothermal field were analyzed.The samples are poorly crystallized Si-Fe-Mn oxyhydroxides with minor birnessite, todorokite, nontronite, goethite, and opal-A.There are some microtextures which are rather like fossil microbes such as the filamentous silica and the hollow pipes.Flakes of nontronite crystals are found either forming a honeycomb texture or distrib- uted on the surface of the hollow pipes.Nontronite is the product precipitated from low-temperature hydrothermal fluids, and microbes may play a role in its formation.Si-Fe-Mn oxyhydroxides have two kinds of nuclei: Si-Mn nuclei and Si nuclei, both enveloped by the similar Si-Fe outer layer, existing in the rod-shaped oxyhydroxide and spheroidal oxyhydroxide, respectively.In the Si-Mn nuclei, the concentration of SiO2 is between 39.32 wt% and 86.31 wt%, and MnO concentration is between 4.97 wt% and 27.01 wt%, but Fe2O3 concentration is very low (0.54 wt%-3.43 wt%).In the Si nucleus the concentration of SiO2 is 90.17 wt%, but concentration of MnO and Fe2O3 are low, with 0.06 wt% and 3.47 wt%, respectively.The formation of the Si-Mn nucleus is closely related to microbes, whereas the Si nucleus is of inorganic origin. | ZENG ZhiGang CHEN Shuai WANG XiaoYuan OUYANG HeGen YIN XueBo LI ZhaoXue | 2012 | Science China Earth Sciences2012，55，12： | 7 |

| 8 | The study of antioxidant activities of fucoidan from Laminaria japonica显示文摘Two large molecular weight fucoidan fractions F-A and F-B were obtained by water extraction and anion-exchange chromatography and then L-A and L-B with low molecular weight and uronic acid content were prepared by radical process degradation of F-A and F-B. The antioxidant activities of the fucoidan fractions on two oxygen free radicals and Cu2+-induced low-density lipoprotein (LDL) oxidation were studied. The results show that all the fucoidan fractions had excellent scavenging capacities on superoxide radical and hypochlorous acid, except the highly sulfated fraction L-B. In LDL oxidation system, low molecular weight fractions L-A and L-B exhibited great inhibitory effects on LDL oxidation induced by Cu2+, however F-A and F-B had little inhibitory effects in this system due to their large molecular weights. The present results suggest that fucoidan from Laminaria japonica is an excellent natural antioxidant and has great potential for preventing the free radical-mediated diseases. | ZhaoXue XueChanghu CaiYuepiao WangDongfeng FangYu | 2005 | High Technology Letters2005，11，1： | 7 |
| 9 | Safety and survival outcomes of transanal natural orifice specimen extraction using prolapsing technique for patients with middle-to low-rectal cancer显示文摘Objective:The transanal approach to specimen collection,combined with the prolapsing technique,is a wellestablished and minimally invasive surgery for treating rectal cancer.However,reports on outcomes for this approach are sparse.We compared short-and long-term outcomes of conventional laparoscopic surgery(CLS)vs.transanal natural orifice specimen extraction(NOSE)using the prolapsing technique for patients with middle-to low-rectal cancer.Methods:From January 2013 to December 2017,we enrolled consecutive patients with middle-to low-rectal cancer undergoing laparoscopic anterior resection.Totally,50 patients who underwent transanal NOSE using the prolapsing technique were matched with 50 patients who received CLS.Clinical parameters and survival outcomes between the two groups were compared.Results:Estimated blood loss(29.70±29.28 vs.52.80±45.09 mL,P=0.003),time to first flatus(2.50±0.79 vs.2.86±0.76,P=0.022),time to liquid diet(3.62±0.64 vs.4.20±0.76 d,P<0.001),and the need for analgesics(22%vs.48%,P=0.006)were significantly lower for the NOSE group compared to the CLS group.The incidences of overall complications and fecal incontinence were comparable in both groups.After a median follow-up of 44.52 months,the overall local recurrence rate(6%vs.5%,P=0.670),3-year disease-free survival(86.7%vs.88.0%,P=0.945)and 3-year overall survival(95.6%vs.96.0%,P=0.708),were not significantly different.Conclusions:For total laparoscopic rectal resection,transanal NOSE using the prolapsing technique is effective and safe,and associated with less trauma and pain,a faster recovery,and similar survival outcomes compared to CLS. | Zhao Lu Haipeng Chen Mingguang Zhang Xu Guan Zhixun Zhao Zheng Jiang Zheng Liu Zhaoxu Zheng Xishan Wang | 2020 | Chinese Journal of Cancer Research2020，32，5： | 6 |
| 10 | The dynamic changes of arsenic biotransformation and bioaccumulation in muscle of freshwater food fish crucian carp during chronic dietborne exposure显示文摘Dietary uptake is the major way that inorganic arsenic(iAs)enters into benthic fish;however,the metabolic process of dietborne i As in fish muscle following chronic exposure remains unclear.This was a 40-day study on chronic dietborne i As[arsenite(AsⅢ)and arsenate(AsⅤ)]exposure in the benthic freshwater food fish,the crucian carp(Carassius auratus),which determined the temporal profiles of iAs metabolism and toxicokinetics during exposure.We found that an adaptive response occurred in the fish body after iAs dietary exposure,which was associated with decreased As accumulation and increased As transformation into a non-toxic As form(arsenobetaine).The bioavailability of dietary AsⅢwas lower than that of AsⅤ,probably because AsⅢhas a lower ability to pass through fish tissues.Dietary AsⅤexhibited a high potential for transformation into AsⅢspecies,which then accumulated in fish muscle.The largely produced AsⅢconsidered more toxic at the earlier stage of AsⅤexposure should attract sufficient attention to human exposure assessment.Therefore,the pristine As species and exposure duration had significant effects on As bioaccumulation and biotransformation in fish.The behavior determined for dietborne arsenic in food fish is crucial for not only arsenic ecotoxicology but also food safety. | Di Cui Peng Zhang Haipu Li Zhaoxue Zhang Yang Song Zhaoguang Yang | 2021 | Journal of Environmental Sciences2021，33，2： | 5 |
| 11 | The Structural Characterization and Antigenicity of the S Protein of SARS-CoV显示文摘The corona-like spikes or peplomers on the surface of the virion under electronicmicroscope are the most striking features of coronaviruses. The S (spike) proteinis the largest structural protein, with 1,255 amino acids, in the viral genome. Itsstructure can be divided into three regions: a long N-terminal region in the exte-rior, a characteristic transmembrane (TM) region, and a short C-terminus in theinterior of a virion. We detected fifteen substitutions of nucleotides by comparisonswith the seventeen published SARS-CoV genome sequences, eight (53.3%) of whichare non-synonymous mutations leading to amino acid alternations with predictedphysiochemical changes. The possible antigenic determinants of the S protein arepredicted, and the result is confirmed by ELISA (enzyme-linked immunosorbentassay) with synthesized peptides. Another profound finding is that three disulfidebonds are defined at the C-terminus with the N-terminus of the E (envelope) pro-tein, based on the typical sequence and positions, thus establishing the structuralconnection with these two important structural proteins, if confirmed. Phyloge-netic analysis reveals several conserved regions that might be potent drug targets. | JingxiangLi ChunqingLuo YajunDeng YujunHan LingTang JingWang JiaJi JiaYe FanboJiang ZhaoXu WeiTong WeiWei QingrunZhang ShengbinLi WeiLi HongyanLi YudongLi WeiDong JianWang ShengliBi HuanmingYaug | 2003 | Genomics, Proteomics & Bioinformatics2003，1，2： | 5 |
| 12 | Hydrothermal alteration of plagioclase microphenocrysts and glass in basalts from the East Pacific Rise near 13°N: An SEM-EDS study显示文摘The interactions of seafloor hydrothermal fluid with igneous rocks can result in leaching elements from the rocks,creating potential ore-forming fluids and influencing the chemical compositions of near-bottom seawater.The hydrothermal alteration of plagioclase microphenocrysts and basaltic glass in the pillow basalts from one dredge station(103°57.62′′W,12°50.55′N,water depth 2480 m)on the East Pacific Rise(EPR)near 13°N were analyzed using a scanning electron microscope(SEM)and energy dispersive X-ray spectrometry(EDS).The results show that the edges of the plagioclase microphenocrysts and the basaltic glass fragments are altered but the pyroxene and olivine microphenocrysts in the interior of the pillow basalts appear to be unaffected by the hydrothermal fluids.In addition,our results show that the chemical alteration at the rims of the plagioclase microphenocrysts and the edges of basaltic glass fragments can be divided into separate types of alteration.The chemical difference in hydrothermal alteration of the plagioclase microphenocrysts and the basaltic glass indicate that different degrees of hydrothermal fluid-solid phase interaction have taken place at the surface of the pillow basalts.If the degree of hydrothermal fluid-solid phase interaction is relatively minor,Si,Al,Ca and Na diffuse from the inside of the solid phase out and as a result these elements have a tendency to accumulate in the edge of the plagioclase microphenocrysts or basaltic glass.If the degree of hydrothermal fluid-solid phase interaction is relatively strong,Si,Al,Ca and Na also diffuse from the inside of solid phase out but these elements will have a relatively low concentration in the edge of the plagioclase microphenocrysts or basaltic glass.Based on the chemical variation observed in the edges of plagioclase microphenocrysts and basaltic glass,we estimate that the content of Si,Al and Fe in the edges of plagioclase microphenocrysts can have a variation of 10.69%,17.59%and 109%,respectively.Similarly,the Si,Al and Fe concentrations in the edges of basaltic glass can have a variation of 9.79%,16.30%and 37.83%,respectively,during the interaction of hydrothermal fluids and seafloor pillow basalt. | ZENG ZhiGang QI HaiYan CHEN Shuai YIN XueBo LI ZhaoXue | 2014 | Science China Earth Sciences2014，57，7： | 5 |

| 17 | Photocatalytic remediation of γ-HCH contaminated soil induced by α-Fe_2O_3 and TiO_2显示文摘Heterogeneous photocatalytic degradation of γ-HCH on soil surfaces was carried out to evaluate the photocatalytic effectiveness of α-Fe 2O 3 and TiO 2 toward degrading γ-HCH on soil surfaces. After being spiked with γ-HCH, soil samples were loaded with α-Fe 2O 3 or TiO 2 and exposed to UV-light irradiation. Different catalyst loads, 0%, 2%, 5%, 7%, and 10% (wt.)α-Fe 2O 3; 0%, 0.5%, 1%, 2:(wt.)TiO 2, were tested for up to 7 d irradiation. The effects of soil thickness, acidity, and humic substances were also investigated. The obtained results indicated that the γ-HCH photodegradation follows the pseudo-first-order kinetics. The addition of α-Fe 2O 3 or TiO 2 accelerates the photodegradation of γ-HCH, while the photodegradation rate decreases when the content of α-Fe 2O 3 exceeds 7%(wt.). The degradation rate increases with the soil pH value. Humic substances inhibit the photocatalytic degradation of γ-HCH. Pentachlorocyclohexene, tetrachlorocyclohexene, and trichlorobenzene are detected as photodegradation intermediates, which are gradually degraded with the photodegradation evolution. | ZHAOXu QUANXie ZHAOYa-zhi ZHAOHui-min CHENShuo CHENJing-wen | 2004 | Journal of Environmental Sciences2004，16，6： | 4 |

| 19 | Carbon matrix effects on the micro-structure and performance of Pt nanowire cathode prepared by decal transfer method显示文摘High performance cathode for polymer electrolyte membrane fuel cell was prepared by depositing Pt nanowires in a carbon matrix coated on a substrate, and using decal transfer method to fabricate the membrane electrode assembly. The effects of carbon and ionomer contents on the electrode micro-structure and fuel cell performance are investigated by physical characterization and single cell testing. The Pt nanowires are gradient distributed across the cathode thickness, and more Pt exists near the membrane. Both the carbon and ionomer contents can affect the Pt nanowires distribution and aggregation. In addition, the carbon loading dominates the transport distance of gas and proton, and the ionomer content affects the triple phase boundaries and porosity in the cathode. The optimal structure of Pt nanowire cathode is obtained at0.10 mg cm-2carbon loading and 10 wt% ionomer. | Zhaoxu Wei An He Kaihua Su Sheng Sui | 2015 | Journal of Energy Chemistry2015，24，2： | 3 |
