| 4 | Optimal time for mesenchymal stem cell transplantation in rats with myocardial infarction显示文摘Background:Bone marrow mesenchymal stem cell (MSC) transplantation is a promising strategy in the treatment of myocardial infarction (MI). However, the time for transplanting cells remains controversial. The aim of this study was to find an optimal time point for cell transplantation. Methods: MSCs were isolated and cultured from Sprague-Dawley (SD) rats. MI model was set up in SD rats by permanent ligation of left anterior descending coronary artery. MSCs were directly injected into the infarct border zone at 1 h, 1 week and 2 weeks after MI, respectively. Sham-operated and MI control groups received equal volume of phosphate buffered saline (PBS). At 4 weeks after MI, cardiac function was assessed by echocardiography; vessel density was analyzed on hematoxylin-eosin stained slides by light microscopy; the apoptosis of cardiomyocytes was evaluated by terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL) assay; the expressions of proteins were analyzed by Western blot. Results: MSC transplantation improved cardiac function, reduced the apoptosis of cardiomyocytes and increased vessel density. These benefits were more obvious in 1-week group than in 1-h and 2-week groups. There are more obvious in-creases in the ratio of bcl-2/bax and the expression of vascular endothelial growth factor (VEGF) and more obvious decreases in the expression of cleaved-caspase-3 in 1-week group than those in other two groups. Conclusion: MSC transplantation was beneficial for the recovery of cardiac function. MSC transplantation at 1 week post-MI exerted the best effects on increases of cardiac function, anti-apoptosis and angiogenesis. | Chen-yang JIANG Chun GUI Ai-na HE Xin-yang HU Jie CHEN Yun JIANG Jian-an WANG | 2008 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2008,9,8: | 18 |

| 6 | Discrimination of abiogenic and biogenic alkane gases显示文摘We have combined the analytical data of the carbon isotope distribution pattern, R/Ra and CH4/3He values of abiogenic and biogenic (referring to the thermogenic and bacterial or microbial) alkane gases in China with those of alkane gases from USA, Russia, Germany, Australia and other countries. Four discrimination criteria are derived from this comparative study: 1) Carbon isotopic composition is generally greater than -30‰ for abiogenic methane and less than -30‰ for biogenic methane; 2) Abiogenic alkane gases have a carbon isotopic reversal trend (δ 13C1> δ 13C2> δ 13C3> δ 13C4) with δ 13C1>-30‰ in general; 3) Gases with R/Ra >0.5 and δ 13C11 δ 13C2>0 are of abiogenic origin; 4) Gases (meth- ane) with CH4/3He≤106 are of abiogenic origin, whereas gases with CH4/3He≥1011 are of biogenic origin. | DAI JinXing ZOU CaiNeng ZHANG ShuiChang LI Jian NI YunYan HU GuoYi LUO Xia TAO ShiZhen ZHU GuangYou MI JingKui LI ZhiSheng HU AnPing YANG Chun ZHOU QingHua SHUAI YanHua ZHANG Ying MA ChengHua | 2008 | Science China Earth Sciences2008,51,12: | 17 |

| 9 | Calcium channel blockers reduce severe fever with thrombocytopenia syndrome virus (SFTSV) related fatality显示文摘Severe fever with thrombocytopenia syndrome (SFTS),an emerging tick-borne infectious disease caused by a novel phlebovirus (SFTS virus, SFTSV), was listed among the top 10 priority infectious diseases by the World Health Organization due to its high fatality of 12%-50% and possibility of pandemic transmission. Currently, effective anti-SFTSV intervention remains unavailable. Here, by screening a library of FDA-approved drugs, we found that benidipine hydrochloride, a calcium channel blocker (CCB), inhibited SFTSV replication in vitro. Benidipine hydrochloride was revealed to inhibit virus infection through impairing virus internalization and genome replication. Further experiments showed that a broad panel of CCBs, including nifedipine, inhibited SFTSV infection. The anti-SFTSV effect of these two CCBs was further an a lyzed in a humanized mouse model in which CCB treatment resulted in reduced viral load and decreased fatality rate. Importantly, by performing a retrospective clinical investigation on a large cohort of 2087 SFTS patients, we revealed that nifedipine administration enhaneed virus clearance, improved clinical recovery, and remarkably reduced the case fatality rate by >5-fold. These findings are highly valuable for developing potential host-oriented therapeutics for SFTS and other lethal acute viral infections known to be inhibited by CCBs in vitro. | Hao Li Lei-Ke Zhang Shu-Fen Li Shao-Fei Zhang Wei-Wei Wan Yu-Lan Zhang Qi-Lin Xin Ke Dai Yuan-Yuan Hu Zhi-Bo Wang Xiang-Tao Zhu Yu-Jie Fang Ning Cui Pan-He Zhang Chun Yuan Qing-Bin Lu Jie-Ying Bai Fei Deng Geng-Fu Xiao Wei Liu Ke Peng | 2019 | Cell Research2019,29,9: | 15 |
| 10 | A New Soil Infiltration Technology for Decentralized Sewage Treatment:Two-Stage Anaerobic Tank and Soil Trench System显示文摘The low removal effciency of total nitrogen(TN) is one of the main disadvantages of traditional single stage subsurface infiltration system,which combines an anaerobic tank and a soil filter field.In this study,a full-scale,two-stage anaerobic tank and soil trench system was designed and operated to evaluate the feasibility and performances in treating sewage from a school campus for over a one-year monitoring period.The raw sewage was prepared and fed into the first anaerobic tank and second tank by 60% and 40%,respectively.This novel process could decrease chemical oxygen demand with the dichromate method by 89%-96%,suspended solids by 91%-97%,and total phosphorus by 91%-97%.The denitrification was satisfactory in the second stage soil trench,so the removals of TN as well as ammonia nitrogen(NH+4-N) reached 68%-75% and 96%-99%,respectively.It appeared that the removal effciency of TN in this two-stage anaerobic tank and soil trench system was more effective than that in the single stage soil infiltration system.The effuent met the discharge standard for the sewage treatment plant(GB18918-2002) of China. | YE Chun HU Zhan-Bo KONG Hai-Nan WANG Xin-Ze HE Sheng-Bing | 2008 | Pedosphere2008,18,3: | 14 |
| 11 | Indirect mineral carbonation of titanium-bearing blast furnace slag coupled with recovery of TiO_2 and Al_2O_3显示文摘Large quantities of CO_2 and blast furnace slag are discharged in the iron and steel industry. Mineral carbonation of blast furnace slag can offer substantial CO_2 emission reduction and comprehensive utilization of the solid waste.This paper describes a novel route for indirect mineral carbonation of titanium-bearing blast furnace(TBBF) slag,in which the TBBF slag is roasted with recyclable(NH_4)_2SO_4(AS) at low temperatures and converted into the sulphates of various valuable metals, including calcium, magnesium, aluminium and titanium. High value added Ti-and Al-rich products can be obtained through stepwise precipitation of the leaching solution from the roasted slag. The NH_3 produced during the roasting is used to capture CO_2 from flue gases. The NH_4HCO_3 and(NH_4)_2CO_3 thus obtained are used to carbonate the CaSO_4-containing leaching residue and MgSO_4-rich leaching solution, respectively. In this study, the process parameters and efficiency for the roasting, carbonation and Ti and Al recovery were investigated in detail. The results showed that the sulfation ratios of calcium,magnesium, titanium and aluminium reached 92.6%, 87% and 84.4%, respectively, after roasting at an AS-to-TBBF slag mass ratio of 2:1 and 350 °C for 2 h. The leaching solution was subjected to hydrolysis at 102 °C for 4 h with a Ti hydrolysis ratio of 95.7% and the purity of TiO_2 in the calcined hydrolysate reached 98 wt%.99.7% of aluminium in the Ti-depleted leaching solution was precipitated by using NH_3. The carbonation products of Ca and Mg were CaCO_3 and(NH_4)_2 Mg(CO_3)_2·4H_2O, respectively. The latter can be decomposed into MgCO_3 at 100–200 °C with simultaneous recovery of the NH_3 for reuse. In this process, approximately 82.1% of Ca and 84.2%of Mg in the TBBF slag were transformed into stable carbonates and the total CO_2 sequestration capacity per ton of TBBF slag reached up to 239.7 kg. The TiO_2 obtained can be used directly as an end product, while the Al-rich precipitate and the two carbonation products can act, respectively, as raw materials for electrolytic aluminium,cement and light magnesium carbonate production for the replacement of natural resources. | Lin Wang Weizao Liu Jingpeng Hu Qiang Liu Hairong Yue Bin Liang Guoquan Zhang Dongmei Luo Heping Xie Chun Li | 2018 | Chinese Journal of Chemical Engineering2018,26,3: | 14 |
| 12 | Effects of Cypermethrin on Male Reproductive System in Adult Rats显示文摘Objective To evaluate effects of cypermethrin on the testis histology and testosterone, LH and FSH in adult male Sprague‐Dawley rats. Methods The intact adult male rats were randomly divided into five groups and were treated with cypermethrin at doses of 0, 7.5, 15, 30, or 60 mg/kg per day by oral gavage for 15‐days. After the treatments, serum was collected for hormone assays. The testes, epididymides, seminal vesicles, and prostates were excised and weighed. The right testis was frozen for daily sperm production and the left one was processed for histopathology. Results Daily sperm production decreased significantly in 30 and 60 mg/(kg day) groups. Testicular structure abnormalities included atrophic and distorted seminiferous tubules, deformed and disordered arrangement of germ cells, reduced germ cells, Sertoli cells and Leydig cells, vacuolization and multinucleated formations of spermatids in the cypermethrin‐treated rats. Vacuolization was found in Sertoli cells and the deformed nucleus was noted in Leydig cells. Serum testosterone reduced significantly in 30 and 60 mg/(kg day) groups. Serum FSH increased significantly in 60 mg/(kg day) group. Conclusion Cypermethrin induces impairments of the seminiferous tubules structure and spermatogenesis in the rats. The damages of the male reproductive system may be attributed to the imbalance of circulating testosterone. | LI Yan Fang PAN Chen HU Jin Xia LI Jing XU Li Chun | 2013 | Biomedical and Environmental Sciences2013,26,3: | 13 |
| 13 | Photoproducts of tetracycline and oxytetracycline involving self-sensitized oxidation in aqueous solutions:Effects of Ca^(2+) and Mg^(2+)显示文摘Tetracyclines constitute one of the most important antibiotic families and represent a classic example of phototoxicity.The photoproducts of tetracyclines and their parent compounds have potentially adverse effects on natural ecosystem.In this study,the self-sensitized oxidation products of tetracycline (TC) and oxytetracycline (OTC) were determined and the effects of Ca2+ and Mg2+ on self-sensitized degradation were investigated.The Ca2+ and Mg2+ in the natural water sample accounted for enhancement (pH 7.3) and inhibition (pH 9.0) of photodegradation of TC and OTC due to the formation of metal-ions complexes.The formation of Mg2+ complexes was unfavorable for the photodegradation of the tetracyclines at both pH values.In contrast,the Ca2+ complexes facilitated the attack of singlet oxygen (1O2) arising from self-sensitization at pH 7.3 and enhanced TC photodegradation.For the first time,selfsensitized oxidation products of TC and OTC were verified by quenching experiments and detected by LC/ESI-DAD-MS.The products had a nominal mass 14 Da higher than the parent drugs (designated M+14),which resulted from the 1O2 attack of the dimethylamino group on the C-4 atom of the tetracyclines.The presence of Ca2+ and Mg2+ also affected the generation of M+14 due to the formation of metal-ions complexes with TC and OTC.The findings suggest that the metal-ion complexation has significant impact on the selfsensitized oxidation processes and the photoproducts of tetracyclines. | Yong Chen Hua Li Zongping Wang Tao Tao Chun Hu | 2011 | Journal of Environmental Sciences2011,23,10: | 12 |

| 15 | Fabrication of submicron barium sulfate aggregates in the presence of ethylenediaminetetraacetic acid anions显示文摘Barium sulfate aggregates with an average size of 0.5 μm were synthesized at pH 7,directed by ethylenediaminetetraacetic acid(EDTA) anions.The particle morphology,chemical composition,and size distribution of the BaSO_4 aggregates were characterized.The as-synthesized BaSO_4 particles were spherical and comprised many interconnected nanoballs,of which the surface properties were affected by the EDTA anions.The adsorption of EDTA anions reversed the charge and weakened the surface polarity of BaSO_4,instigating the formation of aggregates by a self-assembly and transformation process.The resulting BaSO_4 particles at pH 9-10 were ellipsoidal and featured smooth surfaces.Based on the zeta potential of BaSO_4,variations in the morphology induced by changes in pH were closely related to the adsorption of mono- and multi-valent anions onto the electrical double layer of BaSO_4. | Linna Hu Guangxiu Wang Chun Yang Rong Cao | 2015 | Particuology2015,13,5: | 11 |
| 16 | Effects of O3/Cl2 disinfection on corrosion and opportunistic pathogens growth in drinking water distribution systems显示文摘The effects of O_3/Cl_2 disinfection on corrosion and the growth of opportunistic pathogens in drinking water distribution systems were studied using annular reactors(ARs).The corrosion process and most probable number(MPN) analysis indicated that the higher content of iron-oxidizing bacteria and iron-reducing bacteria in biofilms of the AR treated with O_3/Cl_2 induced higher Fe_3O_4 formation in corrosion scales.These corrosion scales became more stable than the ones that formed in the AR treated with Cl_2 alone.O_3/Cl_2 disinfection inhibited corrosion and iron release efficiently by changing the content of corrosion-related bacteria.Moreover,ozone disinfection inactivated or damaged the opportunistic pathogens due to its strong oxidizing properties.The damaged bacteria resulting from initial ozone treatment were inactivated by the subsequent chlorine disinfection.Compared with the AR treated with Cl_2 alone,the opportunistic pathogens M.avium and L.pneumophila were not detectable in effluents of the AR treated with O_3/Cl_2,and decreased to(4.60 ± 0.14) and(3.09 ± 0.12) log10(gene copies/g corrosion scales) in biofilms,respectively.The amoeba counts were also lower in the AR treated with O_3/Cl_2.Therefore,O_3/C_l2 disinfection can effectively control opportunistic pathogens in effluents and biofilms of an AR used as a model for a drinking water distribution system. | Haibo Wang Chun Hu Suona Zhang Lizhong Liu Xueci Xing | 2018 | Journal of Environmental Sciences2018,30,11: | 11 |

| 18 | Clinical risk score for invasive fungal diseases in patients with hematological malignancies undergoing chemotherapy:China Assessment of Antifungal Therapy in Hematological Diseases (CAESAR) study显示文摘Invasive fungal disease (IFD) is a major infectious complication in patients with hematological malignancies.In this study,we examined 4889 courses of chemotherapy in patients with hematological diseases to establish a training dataset (n=3500) by simple random sampling to develop a weighted risk score for proven or probable IFD through multivariate regression,which included the following variables: male patients,induction chemotherapy for newly diagnosed or relapsed disease,neutropenia,neutropenia longer than 10 days,hypoalbuminemia,central-venous catheter,and history of IFD.The patients were classified into three groups,which had low (0-10,~1.2%),intermediate (11-15,6.4%),and high risk (> 15,17.5%) of IFD.In the validation set (n=1389),the IFD incidences of the groups were ~1.4%,5.0%,and 21.4%.In addition,we demonstrated that antifungal prophylaxis offered no benefits in low-risk patients,whereas benefits were documented in intermediate (2.1% vs.6.6%,P=0.007) and high-risk patients (8.4% vs.23.3%,P=0.007).To make the risk score applicable for clinical settings,a pre-chemo risk score that deleted all unpredictable factors before chemotherapy was established,and it confirmed that anti-fungal prophylaxis was beneficial in patients with intermediate and high risk of IFD.In conclusion,an objective,weighted risk score for IFD was developed,and it may be useful in guiding antifungal prophylaxis. | Ling Wang Ying Wang Jiong Hu Yuqian Sun He Huang Jing Chen Jianyong Li Jun Ma Juan Li Yingmin Liang Jianmin Wang Yan Li Kang Yu Jianda Hu Jie Jin Chun Wang Depei Wu Yang Xiao Xiaojun Huang | 2019 | Frontiers of Medicine2019,13,3: | 10 |
| 19 | CFD-DEM simulation of the pneumatic conveying of fine particles through a horizontal slit显示文摘Fine particles play a significant role in many industrial processes.To study the dynamic behavior of fine particle and their deposition in rock fractures,the pneumatic conveying of fine particles(approximately100 μm in diameter) through a small-scale horizontal slit(0.41 m × 0.025 m) was studied,which is useful for the sealing technology of underground gas drainage in coal mining production.The CFD-DEM method was adopted to model the gas-particle two-phase flow;the gas phase was treated as a continuum and modeled using computational fluid dynamics(CFD),particle motion and collisions were simulated using the DEM code.Then,the bulk movement of fine particles through a small-scale horizontal slit was explored numerically,and the flow patterns were further investigated by visual inspection.The simulation results indicated that stratified flow or dune flow can be observed at low gas velocities.For intermediate gas velocities,the flow patterns showed pulsation phenomena,and dune flow reappeared in the tail section.Moreover,periodic flow regimes with alternating thick and sparse stream structures were observed at a high gas velocity.The simulation results of the bulk movement of fine particles were in good agreement with the experimental findings,which were obtained by video-imaging experiments.Furthermore,the calculated pressure drop versus gas velocity profile was investigated and compared with relative experimental findings,and the results showed good agreement.Furthermore,the particle velocity vectors and voidage distribution were numerically simulated.Selected stimulation results are presented and provide a reference for the further study of fine particles. | Fubao Zhou Shengyong Hu Yingke Liu Chun Liu Tongqiang Xia | 2014 | Particuology2014,12,5: | 10 |
| 20 | One-year survey of opportunistic premise plumbing pathogens and free-living amoebae in the tap-water of one northern city of China显示文摘In this study, qPCR was used to quantify opportunistic premise plumbing pathogens(OPPPs) and free-living amoebae in 11 tap water samples collected over four seasons from a city in northern China. Results demonstrated that the average numbers of gene copies of Legionella spp. and Mycobacterium spp. were significantly higher than those of Aeromonas spp.(p < 0.05). Legionella spp. and Mycobacterium spp. were 100%(44/44) positively detected while P. aeruginosa and Aeromonas spp. were 79.54%(35/44) and 77.27%(34/44) positively detected. Legionella pneumophila was only detected in 4 samples(4/44), demonstrating its occasional occurrence. No Mycobacterium avium or Naegleria fowleri was detected in any of the samples. The average gene copy numbers of target OPPPs were the highest in summer,suggesting seasonal prevalence of OPPPs. Average gene copy numbers of OPPPs in the taps of low-use-frequency were higher than in taps of high-use-frequency, but the difference was not significant for some OPPPs(p > 0.05). Moderate negative correlations between the chlorine concentration and the gene copy numbers of OPPPs were observed by Spearman analysis(rsranged from -0.311 to -0.710, p < 0.05). However, no significant correlations existed between OPPPs and AOC, BDOC, or turbidity. Moderate positive correlations were observed between the target microorganisms, especially for Acanthamoeba spp., through Spearman analysis(p < 0.05). Based on our studies, it is proposed that disinfectant concentration, season, taps with different-use frequency, OPPP species, and potential microbial correlations should be considered for control of OPPPs in tap water. | Lizhong Liu Xueci Xing Chun Hu Haibo Wang | 2019 | Journal of Environmental Sciences2019,31,3: | 9 |
