1Toxicity and clinical reasonable application of Taoren(Semen Persicae) based on ancient and modern literature research显示文摘OBJECTIVE:To probe the toxicity and relative application theory of the commonly-used traditional Chinese herbal drug Taoren(Semen Persicae),and set up a correct attitude and principle and method to use Taoren(Semen Persicae) for treating the syndrome of stagnation of blood stasis and others in TCM clinic.METHODS:In this study,we analyzed and probed the ancient and modern literature research about Taoren(Semen Persicae),and summarized the realization of its toxicity and application contraindications in ancient herbals and the research assertion of its processing,drug-nature,pharmacologic actions,adverse reaction,and clinical reasonable application in modern literature.RESULTS:We found that some TCM doctors were worried about the effect of Taoren(Semen Persicae) 's disintegrating blood stasis to impair body's healthy Qi and its toxicity,and were not good at using this herb.And some patients were afraid of its toxic and side-effect not to take it.In the ancient and modern literatures some proper hates of Taoren(Semen Persicae) existed,and the toxicity component was also clear-cut,and the applications of Taoren(Semen Persicae) were in many fields especially the gynecological and traumatological diseases.The key root of toxicity generation and unreasonable application of Taoren(Semen Persicae) lies in taking without syndrome differentiation or using with overdosage.CONCLUSION:Under the precondition of correct processing,treatment based on syndrome differentiation,and taking the dosage stipulated by laws to apply Taoren(Semen Persicae) should be quite safe.The ancient and modern literature records and researches about Taoren(Semen Persicae) provide the determinate reference for understanding Taoren(Semen Persicae)'s efficacy and drug-nature(toxicity) more objectively and also for further correctly clinic recognition and research on Taoren(Semen Persicae).Shengyan Xi Linchao Qian Haiying Tong Lifeng Yue Hui Zhao Dawei Wang Dawei Lu Pengcheng Li Xinrong Wang 2013Journal of Traditional Chinese Medicine2013,33,2:5
2New insights on the enhanced non-hydroxyl radical contribution under copper promoted TiO_(2)/GO for the photodegradation of tetracycline hydrochloride显示文摘TiO_(2)/graphene oxide(GO)as photocatalyst in the photo-degradation of multitudinous pollutants has been extensively studied.But its low photocatalytic efficiency is attributed to the high band gap energy which lead to low light utilization.Cu-TiO_(2)/GO was synthesized via the impregnation methods to enhance the catalytic performance.The Cu-TiO_(2)/GO reaction rate constant for photo-degradation of pollutants(tetracycline hydrochloride,TC)was about 1.4 times that of TiO_(2)/GO.In 90 min,the removal ratio of Cu-TiO_(2)/GO for TC was 98%,and the maximum degradation ratio occurred at p H 5.After five cycles,the removal ratio of Cu-Ti O_(2)/GO still exceeded 98%.UV-visible adsorption spectra of Cu-Ti O_(2)/GO showed that its band gap was narrower than TiO_(2)/GO.Electron paramagnetic resonance(EPR)spectra test illustrated the generation rate of·O_(2)^(-)and·OH was higher in Cu-TiO_(2)/GO system than TiO_(2)/GO and TiO_(2) system.The contribution sequence of oxidative species was·O_(2)^(-)>holes(h+)>·OH in both TiO_(2)/GO and Cu-Ti O_(2)/GO system.Interestingly,the contribution of·OH in Cu-TiO_(2)/GO was less than that in TiO_(2)/GO during the photo-degradation process.This phenomenon was attributed to the better adsorption performance of Cu-Ti O_(2)/GO which could reduce the accessibility of TC to·OH in liquid.The enhanced non-hydroxyl radical contribution could be attributed to that the more other active species or sites on(nearby)the surface of Cu-TiO_(2)/GO generated after doping Cu.These results provide a new perspective for the tradition metal-doped conventional catalysts to enhance the removal of organic pollutants in the environment.Sijia Qian Shengyan Pu Ying Zhang Peng Wang Yingchen Bai Bo Lai 2021Journal of Environmental Sciences2021,33,2:4
3Enhanced heterogeneous activation of peroxymonosulfate by boosting internal electron transfer in a bimetallic Fe_(3)O_(4)-MnO_(2) nanocomposite显示文摘Transition metal-based bimetallic oxides can effectively activate peroxymonosulfate(PMS) for the degradation of organic contaminants, which may be attributed to the enhanced electron transfer efficiency between transition metals. Here, we investigated the high-efficiency catalytic activation reaction of PMS on a well-defined bimetallic Fe-Mn nanocomposite(BFMN) catalyst. The surface topography and chemical information of BFMN were simultaneously mapped with nanoscale resolution. Rhodamine B(Rh B, as a model pollutant) was used to evaluate the oxidation activity of PMS activation system. The maximum absorption peak of Rh B obviously blue shifted from 554 nm to 501 nm, and decreased sharply to disappear completely within 60 min. The removal performance is better than most of the reported single transition metal oxide. X-ray photoelectron spectroscopy(XPS) imaging of the BFMN electronic structure after catalytic activation confirmed that the accelerated internal electron transfer is mainly caused by the synergy effect of Mn and Fe sites at the catalysis boundary. The outstanding ability of BFMN for PMS chemical adsorption and activation may attribute to the enhanced covalency and reactivity of Mn-O. These results of this study can advance understandings on the origins of bimetallic oxides activity for PMS activation and developing the efficient metal oxide catalysts in real practice.Qingqing Shi Shengyan Pu Xi Yang Peng Wang Bo Tang Bo Lai 2022Chinese Chemical Letters2022,33,4:1
4Air-drying changes the distribution of Hedley phosphorus pools in forest soils显示文摘Hedley labile phosphorus(P)pools in soil tend to be several times larger than annual forest requirements,even in highly weathered soils characterized by P limitation.The discrepancy between plant and soil P status could be partly attributable to the frequently adopted air-drying pretreatment that tends to increase soil P solubility.In this study,the effects of air-drying on the distribution of Hedley P fractions were examined using soils collected under 4 forest types at Gongga Mountain,southwestern China.The results showed that the microbial biomass P(Pmic)in the organic horizon decreased markedly after air-drying.The concentrations of Hedley labile P in the air-dried samples were 31%–73%more than those in the field-moist samples.Consequently,the air-drying-induced increments of Hedley labile P pools in the surface soil horizons were 0.8–3.8 times the annual plant P requirements.The organic horizon was more susceptible to the air-drying-induced increases in Hedley labile P than the mineral horizon,probably because of the stronger release of Pmicand disruption of soil organic matter.The quality of P,indexed by the ratio of Hedley labile P to slowly cycling P,shifted in favor of the Hedley labile fractions after air-drying,further revealing that air-drying changed the distribution of Hedley P pools in forest soils.These indicated that the effects of air-drying could not be ignored when interpreting the discrepancy between the P status of plants and the Hedley labile P pools in forest soils.To more efficiently evaluate the P status in forest soils via the Hedley fractionation procedure,the use of field-moist soils is recommended.Jipeng WANG Yanhong WU Jun ZHOU Haijian BING Hongyang SUN Ji LUO Shengyan PU 2020Pedosphere2020,30,2:1

6Efficacy of Ciji Hua'ai Baosheng formula on the expressions of vascular endothelial growth factor,kinase insert domain-containing receptor and basic fibroblast growth factor in mouse models of H22 hepatocellular carcinoma显示文摘OBJECTIVE: To investigate the efficacy of Ciji Hua'ai Baosheng formula(CHBF) on microvessel density(MVD) and vascular endothelial growth factor(VEGF), kinase insert domain-containing receptor(KDR) and basic fibroblast growth factor(b FGF) expression in serum and tumor tissue of mice receiving chemotherapy for the treatment of H22 hepatocellular carcinoma.METHODS: Sixty Kunming mice were injected subcutaneously with H22 hepatoma carcinoma cell suspensions into the right anterior armpit. Seven days later, all transplanted tumor were formed and the mice were intraperitoneally injected 200 mg/kg cytoxan(CTX) to establish the models of tumor-bearing mouse chemotherapy, then they were randomly divided into model group, continuing CTX chemotherapy group(CTX group), and three CHBF(117, 58.5 and 29.25 g/kg) groups. After ten days of treatments, histology was observed, contents of VEGF, KDR and b FGF in serum and tumor tissue were measured by enzyme-linked immunosorbent assay(ELISA), VEGF and b FGF protein expression and MVD tagged by CD34 were detected by immunohistochemisty.RESULTS: MVD in CHBF(117, 58.5 g/kg) and CTX groups was significantly lower than that in model group(P < 0.01); expressions of VEGF, KDR and b FGF in serum and tumor tissue in CHBF(117 g/kg)group were less than those in model group(P <0.05; P < 0.01); the expressions of MVD, VEGF and b FGF in tumor tissue of CHBF(117 g/kg) groupwere also less than those in CTX group(P < 0.05;P < 0.01).CONCLUSION: CHBF can effectively reduce the expression of VEGF, KDR and b FGF in serum and tumor tissue, and decrease MVD and delay tumor progression.Zhao Xinyue Xi Shengyan Wang Yanhui Xu Yangxinzi Pollock Galia Su Yu Cheng Yao Loy Guanjie Liu Pei 2017Journal of Traditional Chinese Medicine2017,37,1:1

8SF_(6)catalytic degradation in aγ-Al_(2)O_(3)packed bed plasma system:A combined experimental and theoretical study显示文摘Effective abatement of the greenhouse gas sulphur hexafluoride(SF_(6))waste is of great importance for the environment protection.This work investigates the size effect and the surface properties ofγ-Al_(2)O_(3)pellets on SF_(6)degradation in a packed bed dielectric barrier discharge(PB-DBD)system.Experimental results show that decreasing the packing size improves the filamentary discharges and promotes the ignition and the maintenance of plasma,enhancing the degradation performance at low input powers.However,too small packing pellets decrease the gas residence time and reduce the degradation efficiency,especially for the input power beyond 80 W.Besides,lowering the packing size promotes the generation of SO2,while reduces the yields of S-O-F products,corresponding to a better degradation.After the discharge,the pellet surface becomes smoother with the appearance of S and F elements.Density functional theory calculations show that SF_(6)is likely to be adsorbed at the AlIII site over theγ-Al_(2)O_(3)(110)surface,and it is much more easily to decompose than in the gas phase.The fluorine gaseous products can decompose and stably adsorb on the pellet surface to change the surface element composition.This work provides a better understanding of SF_(6)degradation in a PB-DBD system.Zhaolun Cui Chang Zhou Amin Jafarzadeh Shengyan Meng Yanhui Yi Yufei Wang Xiaoxing Zhang Yanpeng Hao Licheng Li Annemie Bogaerts 2022High Voltage2022,7,6:1

10Effects of Dietary Betaine on Production Perform-ance,Egg Quality and Serum Biochemical Indexes of Layers under Heat Stress Condition显示文摘[Objective]This experiment was conducted to study the effects of dietary betaine on performance,egg quality and serum biochemical parameters of laying hens under heat stress condition. [Method]A total of 600 22-week-old commercial Roman laying hens were randomly divided into five groups,with eight replicates in each group and 15 hens in each replicate. Group I was taken as the positive control group,and laying hens in group I were fed with basal diets in normal thermal environment. Temperature humidity index of group I was between 64. 9 and 68. 9. Group II was taken as the negative control group,and laying hens in group II were fed with basal diets under heat stress condition. Temperature humidity index of group II was higher than 72. Laying hens in groups III-V were fed with basal diets supplemented with 200,400 and 600 mg/kg betaine under heat stress condition respectively,and temperature humidity indexes in groups III-V were all higher than 72. The experiment lasted for 14 weeks. [Results]Results showed that there were no significant differences in average daily feed intake,feed egg ratio and broken egg rate among different test groups( P > 0. 05). Hen-housed laying rate,hen-housed egg yield,serum total protein( TP) content and serum alkaline phosphatase( AKP) activity in group II were significantly lower than those in group I( P < 0. 05). However,activities of glutamic-oxalacetic transaminase( GOT),creatine kinase( CK) and glutamic-pyruvic transaminase( GPT) in group II were significantly higher than those in group I( P < 0. 05). Hen-housed laying rate,hen-housed egg yield and serum TP content in group IV were significantly higher than those in group II( P < 0. 05). Hen-housed egg yield,serum TP content and serum albumin( ALB) content in group V were significantly higher than those in group II( P < 0. 05). Activities of serum CK and GPT in groups IV and V were significantly lower than those in group II( P < 0. 05),serum triglyceride( TG) content in group V was significantly lower than that in group II( P < 0. 05).[Conclusion]Metabolism and physiological function of laying hens could be affected by heat stress,and which caused a decline in performance. Adding of dietary betaine in diets could improve hen-housed egg production and hen-housed laying rate,which could also improve the health of laying hens under heat stress condition. The appropriate dietary adding content of betaine was 400 mg/kg.Hao Shengyan Liu Longsheng Wang Guodong Gu Xian Pan Faming 2017Animal Husbandry and Feed Science2017,9,2:1

12Mineral occurrence for Dachang gold deposit and its impact on gold recovery rate in Qumarleb County,Qinghai显示文摘Based on X-ray diffraction,optical microscopy and scanning electron microscopy analysis of the Dachang gold ore,it is showed that the sulfide of ore is the main carrier minerals of gold. A majority of gold is embedded in pyrite and tetrahedrite as the form of inclusion and a small amount intergrowth with pyrite and gangue mineral,occasionally the presence is in form of monomer natural gold. The main factors which influence the recovery rate are sulfide mineral particle size,and the fine grained sulfide is beneficial for the dissociation and flotation of gold bearing minerals. The monomer dissociation degree of gold bearing minerals can reach91. 3%,when the grinding fineness is less than 0. 074 mm and grain level accounts as 80%. It is not conducive to the flotation of sulfide if the grinding fineness is low or high. It is difficult to completely dissociate the monomer if there is a small amount of pyrite and arsenopyrite in the ore. Therefore,before leaching the gold,it must conduct pretreatment to reach the ideal recovery rate of the gold,like roasting oxidation,pressure oxidation and biological oxidation. The fine microscopic gold has little influence on the gold recovery rate.CHEN Shengyan YAO Xudong JING Xiangyang WANG Chunguang 2014Global Geology2014,17,3:0
13In maize,co-expression of GAT and GR79-EPSPS provides high glyphosate resistance,along with low glyphosate residues显示文摘Herbicide tolerance has been the dominant trait introduced during the global commercialization of genetically modified(GM)crops.Herbicide-tolerant crops,especially glyphosate-resistant crops,offer great advantages for weed management;however,despite these benefits,glyphosate-resistant maize(Zea mays L.)has not yet been commercially deployed in China.To develop a new bio-breeding resource for glyphosate-resistant maize,we introduced a codon-optimized glyphosate N-acetyltransferase gene,gat,and the enolpyruvyl-shikimate-3-phosphate synthase gene,gr79-epsps,into the maize variety B104.We selected a genetically stable high glyphosate resistance(GR)transgenic event,designated GG2,from the transgenic maize population through screening with high doses of glyphosate.A molecular analysis demonstrated that single copy of gat and gr79-epsps were integrated into the maize genome,and these two genes were stably transcribed and translated.Field trials showed that the transgenic event GG2 could tolerate 9000 g acid equivalent(a.e.)glyphosate per ha with no effect on phenotype or yield.A gas chromatography-mass spectrometry(GC–MS)analysis revealed that,shortly after glyphosate application,the glyphosate(PMG)and aminomethylphosphonic acid(AMPA)residues in GG2 leaves decreased by more than 90%compared to their levels in HGK60 transgenic plants,which only harbored the epsps gene.Additionally,PMG and its metabolic residues(AMPA and N-acetyl-PMG)were not detected in the silage or seeds of GG2,even when far more than the recommended agricultural dose of glyphosate was applied.The co-expression of gat and gr79-epsps,therefore,confers GG2 with high GR and a low risk of herbicide residue accumulation,making this germplasm a valuable GR event in herbicide-tolerant maize breeding.Shengyan Li Pengcheng Li Xiangyin Li Ning Wen Yinxiao Wang Wei Lu Min Lin Zhihong Lang 2023aBIOTECH2023,4,4:0
14让抛硬币更环保、更生态的“藻类硬币”显示文摘在很多东方和西方文化中,当人们祈祷好运时,习惯在水体中投掷硬币。然而,这些硬币对那些误以为是食物的动物来说,是个灾难。例如,水生动物有时会将硬币误认为是食物,因此有成千上万的海龟和鱼类因为试图吃硬币而窒息至死。这款“藻类硬币”让人们抛币祈福更环保、更生态。许愿币被扔进水中时,它会自然地分解并喂养水生动植物,成为水生动植物的营养,而不是破坏环境。人与自然的双赢,才能带来好运!Shengyan Gao Xiaowen Lai Jiongjie Wang 2023工业设计2023,,8:0
