| 2 | Preparation and coagulation efficiency of polyaluminium ferric silicate chloride composite coagulant from wastewater of high-purity graphite production显示文摘The aim of the present work was to produce a polyaluminium ferric silicate chloride (PAFSiC) coagulant from acidic and alkaline wastewater of purifying graphite by roasting, and subsequently to evaluate coagulation efficiency of the reagent by treating surface water from the Yellow River as well as municipal wastewater in comparison with the conventional coagulant polyaluminium chloride (PAC). The PAFSiC coagulant was prepared by co-polymerization. The effects of (Al+Fe)/Si molar ratio, OH/(Al+Fe) molar ratio (i.e., γ value), coagulant dosage and pH value of test suspension on the coagulation behavior of FAFSiC and the stability of the PAFSiC were also examined. Results showed that PAFSiC performed more efficiently than PAC in removing turbidity, chemical oxygen demand (COD), and total phosphate (TP). The PAFSiC with a γ value of 2.0 and (Al+Fe)/Si ratio of 5 (PAFSiC 2.0/5) showed excellent coagulation effect for both turbidity and COD, while PAFSiC 1.0/5 was the best for TP. The optimum coagulation pH range of PAFSiC 2.0/5 was 5.0–9.0, slightly wider than that of PAC (6.0–8.0). The process can be easily incorporated into high-purity graphite production plants, thereby reducing wastewater pollution and producing a valuable coagulant. | Xiaoxia Niu Xili Li Jihong Zhao Yigang Ren Yanqin Yang | 2011 | Journal of Environmental Sciences2011，23，7： | 23 |
| 3 | The deep-lake deposit in the Upper Triassic Yanchang Formation in Ordos Basin, China and its significance for oil-gas accumulation显示文摘The deep-lake facies of the Yanchang Formation represents a large outflowing lake basin in the Ordos area. Its deposition can be divided into four stages: lake genetic and expanding stage, peak stage, inversion stage and dying stage. All the stages are obviously consistent with the evolution of depositional environment and the paleoclimate in the region. The study indicates that the lake basin has evolution fluctuations from highstand to lowstand for four times in its evolution history, and the deposition center of the lake has not obviously moved, staying along the Huachi-Yijun belt. The deep lake sedimentary system mainly consists of deep water deltas and turbidite fans during the entire evolution course of the lake basin in the Late Triassic. The former mainly developed on the slope of steep shore of the delta in the early period of the deep-water expansion and gradually experienced a big shift from deep-water deltas to shallow-water platform delta. And the latter appeared almost in all the above stages and had two types of turbidite fans, slope-moving turbidite fans and slump turbidite fans. The slope-moving turbidite fans have relatively complete facies belts overlapping one another vertically and consist of the slope channel of inter fans, the turbidite channel, inter turbidite channel and turbidite channel front of middle fans and outer fans (or lakebottom plain). However, the slide-moving turbidity fans are formed in the deep lake with their microfacies difficult to be distinguished, and only the center microfacies and edge microfacies can be determined. The two types of the turbidity fans are similarly distributing in the near-root-slope and far-root-slope regions. The deep-lake deposition governs the distribution of the hydrocarbon and reservoir, while the slope-moving turbidite fans are excellent reservoirs for oil-gas exploration due to their great thickness, widespread distribution and accumulation properties. | CHEN QuanHong LI WenHou GAO YongXiang GUO YanQin FENG JuanPing ZHANG DaoFeng CAO HongXia LIANG JiWei | 2007 | Science China Earth Sciences2007，50，z2： | 12 |
| 4 | Chemical characteristics of haze particles in Xi'an during Chinese Spring Festival: Impact of fireworks burning显示文摘Fireworks burning releases massive fine particles and gaseous pollutants, significantly deteriorating air quality during Chinese Lunar New Year(LNY) period. To investigate the impact of the fireworks burning on the atmospheric aerosol chemistry, 1-hr time resolution of PM_(2.5) samples in Xi'an during the winter of 2016 including the LNY were collected and detected for inorganic ions, acidity and liquid water content(LWC) of the fine aerosols. PM_(2.5) during the LNY was 167 ± 87 μg/m^3, two times higher than the China National Ambient Air Quality Standard(75 μg/m^3). K^+(28 wt.% of the total ion mass) was the most abundant ion in the LNY period, followed by SO_4^(2-)(25 wt.%) and Cl-(18 wt.%). In contrast, NO_3^-(34 wt.%) was the most abundant species in the haze periods(hourly PM32-2.5> 75 μg/m), followed by SO_4(29.2 wt.%) and NH_4^+(16.3 wt.%), while SO_4^(2-)(35 wt.%) was the most abundant species in the clean periods(hourly PM_(2.5)< 75 μg/m^3), followed by NO_3^-(23.1 wt.%) and NH_4^+(11 wt.%). Being different from the acidic nature in the non-LNY periods, aerosol in the LNY period presented an alkaline nature with a pH value of 7.8 ± 1.3. LWC during the LNY period showed a robust linear correlation with K_2SO_4 and KCl, suggesting that aerosol hygroscopicity was dominated by inorganic salts derived from fireworks burning. Analysis of correlations between the ratios of NO--3/SO_4^(2-) and NH_4^+/SO_4^(2-) indicated that heterogeneous reaction of HNO_3 with NH_3 was an important formation pathway of particulate nitrate and ammonium during the LNY period. | Can Wu Gehui Wang Jiayuan Wang Jianjun Li Yanqin Ren Lu Zhang Cong Cao Jin Li Shuagshuang Ge Yuning Xie Xinpei Wang Guoyan Xue | 2018 | Journal of Environmental Sciences2018，30，9： | 10 |
| 5 | Wnt/β-catenin signaling in cancers and targeted therapies显示文摘Wnt/β-catenin signaling has been broadly implicated in human cancers and experimental cancer models of animals.Aberrant activation of Wnt/β-catenin signaling is tightly linked with the increment of prevalence,advancement of malignant progression,development of poor prognostics,and even ascendence of the cancer-associated mortality.Early experimental investigations have proposed the theoretical potential that efficient repression of this signaling might provide promising therapeutic choices in managing various types of cancers.Up to date,many therapies targeting Wnt/β-catenin signaling in cancers have been developed,which is assumed to endow clinicians with new opportunities of developing more satisfactory and precise remedies for cancer patients with aberrant Wnt/β-catenin signaling. | Fanyuan Yu Changhao Yu Feifei Li Yanqin Zuo Yitian Wang Lin Yao Chenzhou Wu Chenglin Wang Ling Ye | 2021 | Signal Transduction and Targeted Therapy2021，6，9： | 8 |
| 6 | Ce and Er Co-doped TiO2 for rapid bacteria- killing using visible light显示文摘Bacterial infection and related diseases are threatening the health of human beings.Photocatalytic disinfection as a simple and low-cost disinfection strategy is attracting more and more attention.In this work,TiO2 nanoparticles(NPs)were modified by co-doping of Ce and Er using the sol-gel method,which endowed TiO2 NPs with enhanced visible light photocatalytic performance but not pure ultraviolet photocatalytic properties compared the untreated TiO2.Our results disclosed that as the doping content of Er increased,the photocatalytic activity of modified TiO2 NPs initially increased and subsequently decreased.The same trend occurred for Ce doping.When the doping dose of Er and Ce is 0.5 mol%and 0.2 mol%,the 0.5Ce0.2Ti-O calcined at 800℃ presented the best antibacterial properties,with the antibacterial efficiency of 91.23%and 92.8%for Staphylococcus aureus and Escherichia coli,respectively.The existence of Er ions is thought to successfully turn the near-infrared radiation into visible region,which is easier to be absorbed by TiO2 NPs.Meanwhile,the addition of Ce ions can effectively extend spectral response range and inhibit the recombination of electrons and holes,enhancing the photocatalytic disinfection activity of co-doped TiO2. | Yawei Ren Yajing Han Zhaoyang Li Xiangmei Liu Shengli Zhu Yanqin Liang Kelvin Wai Kwok Yeung Shuilin Wu | 2020 | Bioactive Materials2020，5，2： | 7 |
| 7 | Catalytic conversion of lignocellulosic biomass into chemicals and fuels显示文摘In the search of alternative resources to make commodity chemicals and transportation fuels for a low carbon future,lignocellulosic biomass with over 180-billion-ton annual production rate has been identified as a promising feedstock.This review focuses on the state-of-the-art catalytic transformation of lignocellulosic biomass into value-added chemicals and fuels.Following a brief introduction on the structure,major resources and pretreatment methods of lignocellulosic biomass,the catalytic conversion of three main components,i.e.,cellulose,hemicellulose and lignin,into various compounds are comprehensively discussed.Either in separate steps or in one-pot,cellulose and hemicellulose are hydrolyzed into sugars and upgraded into oxygen-containing chemicals such as 5-HMF,furfural,polyols,and organic acids,or even nitrogen-containing chemicals such as amino acids.On the other hand,lignin is first depolymerized into phenols,catechols,guaiacols,aldehydes and ketones,and then further transformed into hydrocarbon fuels,bioplastic precursors and bioactive compounds.The review then introduces the transformations of whole biomass via catalytic gasification,catalytic pyrolysis,as well as emerging strategies.Finally,opportunities,challenges and prospective of woody biomass valorization are highlighted. | Weiping Deng Yunchao Feng Jie Fu Haiwei Guo Yong Guo Buxing Han Zhicheng Jiang Lingzhao Kong Changzhi Li Haichao Liu Phuc T.T.Nguyen Puning Ren Feng Wang Shuai Wang Yanqin Wang Ye Wang Sie Shing Wong Kai Yan Ning Yan Xiaofei Yang Yuanbao Zhang Zhanrong Zhang Xianhai Zeng Hui Zhou | 2023 | Green Energy & Environment2023，8，1： | 6 |
| 8 | Photo-controlled degradation of PLGA/Ti3C2 hybrid coating on Mg-Sr alloy using near infrared light显示文摘A PLGA/Ti_(3)C_(2) hybrid coating was successfully deposited on the surface of magnesium-strontium(Mg-Sr)alloys.Compared with the corrosion current density(icorr)of the Mg-Sr alloy(7.13×10^−5 A/cm^2),the modified samples(Mg/PLGA/Ti_(3)C_(2))was lower by approximately four orders of magnitude(7.65×10^−9 A/cm^2).After near infrared 808 nm laser irradiation,the icorr of the modified samples increased to 3.48×10^−7 A/cm^2.The mechanism is that the local hyperthermia induced the free volume expansion of PLGA,and the increase in intermolecular gap enhanced the penetration of electrolytes.Meanwhile,the cytotoxicity study showed that the hybrid coating endowed the Mg-Sr alloy with enhanced biocompatibility. | Li Liu Bo Huang Xiangmei Liu Wei Yuan Yufeng Zheng Zhaoyang Li Kelvin Wai Kwok Yeung Shengli Zhu Yanqin Liang Zhenduo Cui Shuilin Wu | 2021 | Bioactive Materials2021，6，2： | 4 |

| 10 | Three Tiaobu Feishen therapies protect human alveolar epithelial cells against cigarette smoking and tumor necrosis factor-mlear factor-kappa B pathwayα-induced inflamation by nuc显示文摘OBJECTIVE: To investigate the efficacy of Tiaobu Feishen formulae(TBFS), including Bufei Jianpi formula(BJF), Bufei Yishen formula(BYF), and Yiqi Zishen formula(YZF), on inflammatory response, protease-anti-protease imbalance and collagen deposition in rats.METHODS: In present work, we used an in vitro model of cigarette smoking extract(CSE)-and tumor necrosis factor-α(TNF-α)-induced A549 cellsto examine the efficacy of BJF, BYF and YZF on the production of inflammatory cytokines, including TNF-α and interleukin(IL)-8, IL-6, matrix metalloproteinases(MMP)-9, and IL-10 in CSE or TNF-ls. And their related transcripα-induced A549 celtion factors and signaling pathway were also analyzed.RESULTS: The results showed that BJF, BYF and YZF could significantly decrease the expression levels of the pro-inflammatory cytokines induced by CSE or TNF-α. Furthermore, BJF, BYF and YZF could suppress CSE-or TNF-α-induced activation of nuclear factor-kappa B(NF-κB) transcription factors and its corresponding pathways. Taken together, these data implied that BJF, BYF and YZF effectively inhibited CSE-or TNF-α-induced inflammatory response in alveolar epithelial cell, which was due to their inhibition effect on NF-κB pathways.CONCLUSION: Our findings suggest that the Tiaobu Feishen therapies may protect human alveolar epithelial cells against cigarette smoking and TNF-α-induced inflammation. NF-κB pathway may involve in the actions. | Chen Yulong Wu Yaosong Li Jiansheng Feng Suxiang Hao Lili Liu Xuefang Zheng Wanchun Dong Haoran Qin Yanqin Yin Sugai Zhao Peng | 2019 | Journal of Traditional Chinese Medicine2019，39，1： | 4 |
| 11 | Seasonal variation and size distribution of biogenic secondary organic aerosols at urban and continental background sites of China显示文摘Size-resolved biogenic secondary organic aerosols(BSOA) derived from isoprene and monoterpene photooxidation in Qinghai Lake, Tibetan Plateau(a continental background site) and five cities of China were measured using gas chromatography/mass spectrometry(GC/MS). Concentrations of the determined BSOA are higher in the cities than in the background and are also higher in summer than in winter. Moreover, strong positive correlations(R2= 0.44–0.90) between BSOA and sulfate were found at the six sites,suggesting that anthropogenic pollution(i.e., sulfate) could enhance SOA formation,because sulfate provides a surface favorable for acid-catalyzed formation of BSOA. Size distribution measurements showed that most of the determined SOA tracers are enriched in the fine mode(< 3.3 μm) except for cis-pinic and cis-pinonic acids, both presented a comparable mass in the fine and coarse(> 3.3 μm) modes, respectively. Mass ratio of oxidation products derived from isoprene to those from monoterpene in the five urban regions during summer are much less than those in Qinghai Lake region. In addition, in the five urban regions relative abundances of monoterpene oxidation products to SOA are much higher than those of isoprene. Such phenomena suggest that BSOA derived from monoterpenes are more abundant than those from isoprene in Chinese urban areas. | Yanqin Ren Gehui Wang Jianjun Li Can Wu Cong Cao Jiayuan Wang Lu Zhang Fan Meng Hong Li | 2018 | Journal of Environmental Sciences2018，30，9： | 4 |
| 12 | Overwhelming low ammonia escape and low temperature denitration efficiency via MnOx-decorated two-dimensional MgAl layered double oxides显示文摘Low temperature catalysts are attracting increasing attention in the selective catalytic reduction(SCR)of NO with NH3.Mn Ox-decorated Mg Al layered double oxide(Mn/Mg Al-LDO)was synthesized via a facile fast pour assisted co-precipitation(FP-CP)process.Compared to the Mn/Mg Al-LDO obtained via slow drop assisted coprecipitation(SD-CP)method,the Mn/Mg Al-LDO(FP-CP)has excellent activity.The Mn/Mg Al-LDO(FP-CP)catalyst was shown to possess a high NO conversion rate of 76%-100%from 25 to 150℃,which is much better than the control Mn/Mg Al-LDO(SD-CP)(29.4%-75.8%).In addition,the Mn/Mg Al-LDO(FP-CP)offered an enhanced NO conversion rate of 97%and a N2selectivity of 97.3%at 100℃;the NO conversion rate was 100%and the N2selectivity was 90%at 150℃with a GHSV of 60,000 h^-1.The Mn/Mg Al-LDO(FP-CP)catalyst exhibited a smaller fragment nano-sheet structure(sheet thickness of 7.23 nm).An apparent lattice disorder was observed in the HRTEM image confirming the presence of many defects.The H2-TPR curves show that the Mn/Mg Al-LDO(FP-CP)catalyst has abundant reducing substances.Furthermore,the enhanced surface acidity makes the NH3concentration of the Mn/Mg Al-LDO(FP-CP)catalyst lower than 100 ml·m^-3after the reaction from 25 to 400℃.This can effectively reduce the ammonia escape rate in the SCR reaction.Thus,the Mn/Mg Al-LDO(FP-CP)catalyst has potential applications in stationary industrial installations for environmentally friendly ultra-low temperature SCR. | Junqi Tian Yanqin Li Xia Zhou Yongbin Yao DenghaoWang Jianming Dan Bin Dai Qiang Wang Feng Yu | 2020 | Chinese Journal of Chemical Engineering2020，28，7： | 4 |
| 13 | Hierarchical Ni_(3)S_(4)@MoS_(2)nanocomposites as efficient electrocatalysts for hydrogen evolution reaction显示文摘Hydrogen evolution reaction(HER)through water splitting is a promising way to solve the energy shortage.Noble-metal-free HER electrocatalysts with high efficiency is very important for practical applications.Herein,we prepare the Ni_(3)S_(4)@MoS_(2)electrocatalyst on carbon cloth(CC)through a two-step hydrothermal process.The Ni_(3)S_(4)nanorods are uniformly integrated with the MoS_(2)nanosheets,forming a hierarchical structure and heterogeneous interfaces.The fast electron transfer on the interface enhances the kinetics of catalytic reaction.The hierarchical structure provides more exposed active sites.The Ni_(3)S_(4)@MoS_(2)/CC exhibits good catalytic activity and long-term stability for HER.This work provided a practicable strategy to develop efficient electrocatalysts for HER in alkaline media. | Yuxi Ren Shengli Zhu Yanqin Liang Zhaoyang Li Shuilin Wu Chuntao Chang Shuiyuan Luo Zhenduo Cui | 2021 | Journal of Materials Science & Technology2021，，36： | 3 |
| 14 | Pollution characteristics and health risk assessment of polycyclic aromatic hydrocarbons and nitrated polycyclic aromatic hydrocarbons during heating season in Beijing显示文摘Polycyclic aromatic hydrocarbons(PAHs)and their nitrated derivatives(NPAHs)attract continuous attention due to their outstanding carcinogenicity and mutagenicity.In order to investigate the diurnal variations,sources,formation mechanism,and health risk assessment of them in heating season,particulate matter(PM)were collected in Beijing urban area from December 26,2017 to January 17,2018.PAHs and NPAHs in PM were quantitatively analyzed via gas chromatography-mass spectrometry(GC-MS).Average daily concentrations of PAHs and NPAHs were(78±54)ng/m^(3)and(783±684)pg/m^(3),respectively.The concentrations of them were significantly higher at nighttime than at daytime,and NPAHs concentrations were 1-2 orders of magnitude lower than PAHs concentrations.In the heating season,the dominant species of PAHs include benzo[b]fluoranthene,fluoranthene,pyrene,and chrysene,while 9-nitroanthracene,2+3-nitrofluoranthene,and 2-nitropyrene were dominant species for NPAHs.NPAHs were found to have a single peak during heating and to be primarily distributed in the 0.4-0.7μm particle size.Primary emissions such as biomass burning,coal combustion,and traffic emissions were the major sources of PAHs.NPAHs were produced by the primary source of vehicle emissions and the secondary reaction triggered by OH radicals,as well as biomass burning during daytime.According to the health risk assessment,the total carcinogenic risk was higher in adults than in children.While upon oral ingestion,the carcinogenic risk in children was higher than that of adults,but the risk of adults was higher than children through skin contact and respiratory inhalation. | Xurong Bai Jie Wei Yanqin Ren Rui Gao Fahe Chai Hong Li Fei Xu Yuxue Kong | 2023 | Journal of Environmental Sciences2023，，1： | 3 |
| 15 | Tagging single nucleotide polymorphisms in the PPAR-γ and RXR-α gene and type 2 diabetes risk:a case-control study of a Chinese Han population显示文摘Peroxisome proliferator-activated receptor (PPAR-γ),which is mainly involved in adipocyte differentiation, has been suggested to play an important role in the pathogenesis of insulin resistance and atherosclerosis. We investigated the frequencies of two common tagging polymorphisms of the PPAR-γ gene and two of PPAR-α with minor allele frequency (MAF)≥ 0.05 in the Chinese Han population and analyzed the correlation between the different genotypes and the risk of type 2 diabetes mellitus (T2DM). TaqMan assay was performed to test the genotypes in T2DM patients (n = 1,105) and normal controls (n = 1,107). Serum adiponectin concentration was measured by ELISA kit. The variant genotypes rs17817276GG, rs3856806CT and rs3856806CT/TT of PPAR-γ were associated with T2DM, P = 0.023,0.037 and 0.018, respectively. Furthermore, the prevalence of haplotype GT in PPAR-γ was less frequent in the case subjects (0.3%) than in the controls (1.9%) [P < 0.001,OR(95%CI)=0.13 (0.06-0.31)]. Patients with genotype TT of rs3856806 had a higher serum level of adiponectin than those with the genotype CC and CT (P = 0.031 and 0.038, respectively). There was no statistically significant difference between patients and controls in genotype distribution of rs6537944 and rs1045570 of the RXR-α gene. The present study suggests that the variant genotypes in the PPAR-γ gene could decrease the risk for the development of T2DM in the Chinese Han population. | Juan Du Hui Shi Ying Lu Wencong Du Yuanyuan Cao Qian Li Jianhua Ma Xinhua Ye Jinluo Cheng Xiaofang Yu Yanqin Gao Ling Zhou | 2011 | The Journal of Biomedical Research2011，25，1： | 3 |

| 17 | Application of the back-error propagation artificial neural network(BPANN) on genetic variants in the PPAR-γ and RXR-α gene and risk of metabolic syndrome in a Chinese Han population显示文摘This study was aimed to explore the associations between the combined effects of several polymorphisms in the PPAR-γ and RXR-α gene and environmental factors with the risk of metabolic syndrome by back-error propagation artificial neural network(BPANN).We established the model based on data gathered from metabolic syndrome patients(n = 1012) and normal controls(n = 1069) by BPANN.Mean impact value(MIV) for each input variable was calculated and the sequence of factors was sorted according to their absolute MIVs.Generalized multifactor dimensionality reduction(GMDR) confirmed a joint effect of PPAR-γ and RXR-α based on the results from BPANN.By BPANN analysis,the sequences according to the importance of metabolic syndrome risk factors were in the order of body mass index(BMI).serum adiponectin,rs4240711,gender,rs4842194,family history of type 2 diabetes,rs2920502,physical activity,alcohol drinking,rs3856806,family history of hypertension,rsl045570,rs6537944,age,rsl7817276,family history of hyperlipidemia,smoking,rs1801282 and rs3132291.However,no polymorphism was statistically significant in multiple logistic regression analysis.After controlling for environmental factors,A_1,A_2,B_1 and B_2(rs4240711,rs4842194,rs2920502 and rs3856806) models were the best models(cross-validation consistency 10/10,P = 0.0107) with the GMDR method.In conclusion,the interaction of the PPAR-γ and RXR-α gene could play a role in susceptibility to metabolic syndrome.A more realistic model is obtained by using BPANN to screen out determinants of diseases of multiple etiologies like metabolic syndrome. | Xu Zhao Kang Xu Hui Shi Jinluo Cheng Jianhua Ma Yanqin Gao Qian Li Xinhua Ye Ying Lu Xiaofang Yu Juan Du Wencong Du Qing Ye Ling Zhou | 2014 | The Journal of Biomedical Research2014，28，2： | 3 |
| 18 | The enhanced photocatalytic sterilization of MOF-Based nanohybrid for rapid and portable therapy of bacteria-infected open wounds显示文摘Open wounds are prone to infection and difficult to heal,which even threatens the life of patients because bacterial infections can induce other lethal complications without prompt treatment.The commonly used antibiotics treatment for bacterial infections has been reported to cause globally bacterial resistance and even the occurrence of superbacteria.The highly effective and antibiotic-independent therapeutic strategies are urgently needed for treating various kinds of bacteria-infected diseases.In this work,we synthesized an eco-friendly nanohybrid material(ZnDMZ)consisting of a kind of biodegradable metal organic framework(MOF,ZIF-8)combined with Zn-doped MoS_(2)(Zn-MoS_(2))nanosheets,which exhibited great ability to kill bacteria and promote the healing of bacteria-infected wounds under 660 nm light irradiation.The underlying mechanism is that besides the local hyperthermia,the nanohybrid material exhibits enhanced photocatalytic performance than single component in it,i.e.,it can also be excited by 660 nm light to produce more oxygen radical species(ROS)due to the following factors.On one hand,the Zn doping can reduce the work function and the band gap of MoS_(2),which promotes the movement of photoexcited electrons to the surface of the material.On the other hand,the combination between Zn-MoS_(2) and MOF induces the formation of a built-in electric field due to their work function difference,thus accelerating the separation of photoexcited electron-hole pairs.Because of the synergy of photocatalytic effect,photothermal effect and the released Zn ions,the synthesized ZnDMZ possessed a highly effective antibacterial efficacy of 99.9%against Staphylococcus aureus under 660 nm light irradiation for 20 min without cytotoxicity.In vivo tests showed that this nanohybrid material promoted the wound healing due to the released Zn ions.This nanohybrid will be promising for rapid and portable treatment of bacteria-infected open wounds in pathogenic bacteria contaminated environments. | Chaofeng Wang Yue Luo Xiangmei Liu Zhenduo Cui Yufeng Zheng Yanqin Liang Zhaoyang Li Shengli Zhu Jie Lei Xiaobo Feng Shuilin Wu | 2022 | Bioactive Materials2022，7，7： | 3 |
| 19 | DNA methylation status of H19 and Xist genes in lungs of somatic cell nuclear transfer bovines显示文摘In somatic cell nuclear transfer (SCNT) technologies,the donor cell’s nuclei need to be epigenetically reprogrammed for embryonic development. The incomplete reprogramming of donor cell nuclei has been implicated as a primary reason for the low efficiency of SCNT. DNA methylation is a major epige-netic modification of the genome that regulates crucial aspects of genome function,including estab-lishment of genomic imprinting. In order to make sure whether the DNA methylation reprogramming is efficient in SCNT animals,we analyzed the DNA methylation status of two imprinting genes,H19 and Xist,in lungs of deceased SCNT bovines that died within 48 h of birth using bisulfite sequencing analysis. Our findings demonstrated that cloned bovines showed significantly lower DNA methylation of H19 than controls (P<0.05),and three tested CpGs sites (1,2,3) exhibited unmethylation in one cloned bovine (9C3); however,Xist showed similar DNA methylation levels between clones and con-trols,and both showed hypermethylation (96.11% and 86.67%). | CHEN Jie LI DongJie LIU YanQin ZHANG Cui DAI YunPing LI ShiJie LI Ning | 2008 | Chinese Science Bulletin2008，53，13： | 3 |
| 20 | Oxymatrine Inhibits Bocavirus MVC Replication, Reduces Viral Gene Expression and Decreases Apoptosis Induced by Viral Infection显示文摘Oxymatrine(OMT), as the main active component of Sophoraflavescens, exhibits a variety of pharmacological properties,including anti-oxidative, anti-inflammatory, anti-tumor, and anti-viral activities, and currently is extensively employed to treat viral hepatitis; however, its effects on parvovirus infection have yet to be reported. In the present study, we investigated the effects of OMT on cell viability, virus DNA replication, viral gene expression, cell cycle, and apoptosis in Walter Reed canine cells/3873 D infected with minute virus of canines(MVC). OMT, at concentrations below 4 mmol/L(no cellular toxicity), was found to inhibit MVC DNA replication and reduce viral gene expression at both mRNA and protein levels, which was associated with the inhibition of cell cycle S-phase arrest in early-stage of MVC infection.Furthermore, OMT significantly increased cell viability, decreased MVC-infected cell apoptosis, and reduced the expression of activated caspase 3. Our results suggest that OMT has potential application in combating parvovirus infection. | Yanqin Ding Na Li Jinhan Sun Linran Zhang Jianhui Guo Xueqi Hao Yuning Sun | 2019 | Virologica Sinica2019，34，1： | 2 |
