| 2 | A comparative study of Mn/CeO_2,Mn/ZrO_2 and Mn/Ce-ZrO_2 for low temperature selective catalytic reduction of NO with NH_3 in the presence of SO_2 and H_2O显示文摘Ce-ZrO2 is a widely used three-way catalyst support.Because of the large surface area and excellent redox quality,Ce-ZrO2 may have potential application in selective catalytic reduction(SCR) systems.In the present work,Ce-ZrO2 was introduced into a low-temperature SCR system and CeO2 and ZrO2 supports were also introduced to make a contrastive study.Mn/CeO2,Mn/ZrO2 and Mn/Ce-ZrO2 were prepared by impregnating these supports with Mn(NO3)2 solution,and have been characterized by N2-BET,XRD,TPR,TPD,XPS,FT-IR and TG.The activity and resistance to SO2 and H2O of the catalysts were investigated.Mn/Ce-ZrO2 and Mn/CeO2 were proved to have better low-temperature activities than Mn/ZrO2,and yielded 98.6% and 96.8% NO conversion at 180°C,respectively.This is mainly because Mn/Ce-ZrO2 and Mn/CeO2 had higher dispersion of manganese oxides,better redox properties and more weakly adsorbed oxygen species than Mn/ZrO2.In addition,Mn/Ce-ZrO2 showed a good resistance to SO2 and H2O and presented 87.1% NO conversion,even under SO2 and H2O treatment for 6 hours,and the activity of Mn/Ce-ZrO2 was almost restored to its original level after cutting off the injection of SO2 and H2O.This was due to the weak water absorption and weak sulfation process on the surface of the catalyst. | Boxiong Shen Xiaopeng Zhang Hongqing Ma Yan Yao Ting Liu | 2013 | Journal of Environmental Sciences2013，25，4： | 30 |
| 3 | Enhancing the antihepatitis B virus immune response by adefovir dipivoxil and entecavir therapies显示文摘Chronicity of hepatitis B(CHB)infection is characterized by a weak immune response to the virus.Entecavir(ETV)and adefovir dipivoxil(ADV)are effective in suppressing hepatitis B virus(HBV)replication.However,the underlying immune mechanism in the antiviral response of patients treated with nucleoside or nucleotide analogs is not clearly understood.In this study,regulatory T cells(Tregs)and intracellular cytokines,including IL-2,interferon(IFN)-γ,tumor-necrosis factor(TNF)-α and IL-4,were measured prior to and at 12,24,36 and 48 weeks after treatment with ETV or ADV.The cytokines were increased from 24 to 48 weeks after treatment.Higher levels of Th1 cytokines were observed with ETV(n=29)versus ADV(n=28)treatment.By contrast,the numbers of Tregs in both groups were decreased.The altered cytokine profile and cellular component was accompanied by a decrease in HBV DNA levels in both groups,which may contribute to their therapeutic effect in CHB infection.Our findings suggest that the antiviral effect of the drugs may be attributed not only to their direct effect on virus suppression but also to their immunoregulatory capabilities. | Yanfang Jiang Wanyu Li Lei Yu Jingjing Liu Guijie Xin Hongqing Yan Pinghui Sun Hong Zhang Damo Xu Junqi Niu | 2011 | Cellular & Molecular Immunology2011，8，1： | 16 |
| 4 | Mechanism of lead immobilization by oxalic acid-activated phosphate rocks显示文摘Lead (Pb) chemical fixation is an important environmental aspect for human health. Phosphate rocks (PRs) were utilized as an adsorbent to remove Pb from aqueous solution. Raw PRs and oxalic acid-activated PRs (APRs) were used to investigate the effect of chemical modification on the Pb-binding capacity in the pH range 2.0-5.0. The Pb adsorption rate of all treatments above pH 3.0 reached 90%. The Pb binding on PRs and APRs was pH-independent, except at pH 2.0 in activated treatments. The X-ray diffraction analysis confirmed that the raw PRs formed cerussite after reacting with the Pb solution, whereas the APRs formed pyromorphite. The Fourier Transform Infrared spectroscopy analysis indicated that carbonate (CO32-) in raw PRs and phosphate (PO43-) groups in APRs played an important role in the Pb-binding process. After adsorption, anomalous block-shaped particles were observed by scanning electron microscopy with energy dispersive spectroscopy. The X-ray photoelectron spectroscopy data further indicated that both chemical and physical reactions occurred during the adsorption process according to the binding energy. Because of lower solubility of pyromorphite compared to cerussite, the APRs are more effective in immobilizing Pb than that of PRs. | Guanjie Jiang Yonghong Liu Li Huang Qingling Fu Youjun Deng Hongqing Hu | 2012 | Journal of Environmental Sciences2012，24，5： | 12 |
| 5 | Immobilization of lead in anthropogenic contaminated soils using phosphates with/without oxalic acid显示文摘Understanding the effects of oxalic acid(OA) on the immobilization of Pb(Ⅱ) in contaminated soils by phosphate materials, has considerable benefits for risk assessment and remediation strategies for the soil. A series of phosphate amendments with/without oxalic acid were applied to two anthropogenic contaminated soils. We investigated the immobilization of Pb(Ⅱ) by KH2PO4, phosphate rock(PR), activated phosphate rock(APR) and synthetic hydroxyapatite(HAP) at different phosphate:Pb(P:Pb) molar ratios(0, 0.6, 2.0 and 4.0) in the presence/absence of 50 mmol oxalic acid/kg soil, respectively. The effects of treatments were evaluated using single extraction with deionized water or Ca Cl2, Community Bureau of Reference(BCR) sequential extraction and toxicity characteristic leaching procedure(TCLP)methods. Our results showed that the concentration of water extractable, exchangeable and TCLP-Pb all decreased with incubation time. The concentration of water-extractable Pb after120 days was reduced by 100% when soils were amended with APR, HAP and HAP + OA, and the TCLP-Pb was <5 mg/L for the red soil at P:Pb molar ratio 4.0. Water-soluble Pb could not be detected and the TCLP-Pb was <5 mg/L at all treatments applied to the yellow-brown soil. BCR results indicated that APR was most effective, although a slight enhancement of water-soluble phosphate was detected at the P:Pb molar ratio 4.0 at the beginning of incubation. Oxalic acid activated phosphates, and so mixing insoluble phosphates with oxalic acid may be a useful strategy to improve their effectiveness in reducing Pb bioavailability. | Xiaojuan Su Jun Zhu Qingling Fu Jichao Zuo Yonghong Liu Hongqing Hu | 2015 | Journal of Environmental Sciences2015，27，2： | 9 |

| 7 | Effect of preoperative nutrition therapy type and duration on short-time outcomes in gastric cancer patient with gastric outlet obstruction显示文摘Objective:To avoid perioperative complications caused malnutrition,nutrition therapy is necessary in gastric outlet obstruction(GOO)patients.Compared to parenteral nutrition(PN),enteral nutrition(EN)is associated with many advantages.This study aimed to investigate whether preoperative EN has beneficial clinical effects compared to preoperative PN in gastric cancer patients with GOO undergoing surgery.Methods:According to the methods of preoperative nutrition therapy,143 patients were divided into EN group(n=42)and PN group(n=101)between January 2013 and December 2017 at the Chinese People’s Liberation Army General Hospital.Multiple logistic regression models were used to assess the association between the methods of preoperative nutrition therapy and postoperative day of flatus passage.The generalized additive model and twopiecewise linear regression model were used to calculate the inflection point of the preoperative nutritional therapy time on the postoperative day of flatus passage in the PN group.Results:EN shortened the postoperative day of flatus passage in gastric cancer patients with GOO,which is a protective factor,especially in patients who underwent non-radical operations and the postoperative day of flatus passage reduced when the preoperative PN therapy was up to 3 d and a longer PN therapy(>3 d)did not accelerate the postoperative recovery of gastrointestinal functions.Conclusions:Preoperative EN therapy would benefit gastric cancer patients with GOO by accelerating postoperative recovery.For patients with absolute obstruction,no more than 3-day PN therapy is recommended if patients can tolerate general anesthesia and surgery. | Jiyang Li Shaoqing Li Hongqing Xi Peifa Liu Wenquan Liang Yunhe Gao Chuang Wang Bo Wei Lin Chen Yun Tang Zhi Qiao | 2021 | Chinese Journal of Cancer Research2021，33，2： | 4 |

| 10 | A structure-supporting,self-healing,and high permeating hydrogel bioink for establishment of diverse homogeneous tissue-like constructs显示文摘The ready-to-use,structure-supporting hydrogel bioink can shorten the time for ink preparation,ensure cell dispersion,and maintain the preset shape/microstructure without additional assistance during printing.Meanwhile,ink with high permeability might facilitate uniform cell growth in biological constructs,which is beneficial to homogeneous tissue repair.Unfortunately,current bioinks are hard to meet these requirements simultaneously in a simple way.Here,based on the fast dynamic crosslinking of aldehyde hyaluronic acid(AHA)/N-carboxymethyl chitosan(CMC)and the slow stable crosslinking of gelatin(GEL)/4-arm poly(ethylene glycol)succinimidyl glutarate(PEG-SG),we present a time-sharing structure-supporting(TSHSP)hydrogel bioink with high permeability,containing 1%AHA,0.75%CMC,1%GEL and 0.5%PEG-SG.The TSHSP hydrogel can facilitate printing with proper viscoelastic property and self-healing behavior.By crosslinking with 4%PEG-SG for only 3 min,the integrity of the cell-laden construct can last for 21 days due to the stable internal and external GEL/PEG-SG networks,and cells manifested long-term viability and spreading morphology.Nerve-like,muscle-like,and cartilage-like in vitro constructs exhibited homogeneous cell growth and remarkable biological specificities.This work provides not only a convenient and practical bioink for tissue engineering,targeted cell therapy,but also a new direction for hydrogel bioink development. | Hongqing Chen Fei Fei Xinda Li Zhenguo Nie Dezhi Zhou Libiao Liu Jing Zhang Haitao Zhang Zhou Fei Tao Xu | 2021 | Bioactive Materials2021，6，10： | 2 |

| 12 | The Pumilio RNA-binding protein APUM24 regulates seed maturation by fine-tuning the BPM-WRI1 module in Arabidopsis显示文摘Pumilio RNAbindingproteinsparticipateinmes-senger RNA(mRNA)degradation and t ranslational repression,but their roles in plant development are largely unclear.Here,we show that Arabidopsis PUMILIO PROTEIN24(APUM24),an atypical Pumiliohomology domaincontaining protein,plays an im-portant part in regulating seed maturation,a major stage of plant development.APUM24 is strongly expressed in maturing seeds.Reducing APUM24 expression resulted in abnormal seed maturation,wrinkled seeds,and lower seed oil contents,and APUM24 knockdown resulted in lower levels of WRINKLED 1(WRI1),a key transcription factor con-trolling seed oil accumulation,and lower expression of WRI1 target genes.APUM24 reduces the mRNA stability of BTB/POZMATH(BPM)family genes,thus decreasing BPM protein levels.BPM is responsible for the 26S proteasomemediated degradation of WRI1 and has important functions in plant growth and development.The 3′untranslated regions of BPM family genes contain putative Pumilio response elements(PREs),which are bound by APUM24.Re-duced BPM or increased WRI1 expression rescued the decient seed maturation of apum242 knock-down mutants,and APUM24 overexpression re-sulted in increased seed size and weight.Therefore,APUM24 is crucial to seed maturation through its action as a positive regulatornetuning the BPMWRI1 module,making APUM24 apromising target for breeding strategies to increase crop yields. | Ruihua Huang Mengling Liu Guanping Gong Pingzhi Wu Barunava Patra Ling Yuan Hongting Qin Xiaoxu Wang Guohe Wang Huimei Liao Lu Gao Chengwei Yang Hongqing Li Shengchun Zhang | 2021 | Journal of Integrative Plant Biology2021，63，7： | 2 |
| 13 | Sphingosine kinase 1 promotes growth of glioblastoma by increasing inflammation mediated by the NF-κB/IL-6/STAT3 and JNK/PTX3 pathways显示文摘Glioblastoma(GBM)is the most challenging malignant tumor of the central nervous system because of its high morbidity,mortality,and recurrence rate.Currently,mechanisms of GBM are still unclear and there is no effective drug for GBM in the clinic.Therefore,it is urgent to identify new drug targets and corresponding drugs for GBM.In this study,in silico analyses and experimental data show that sphingosine kinase 1(SPHK1)is up-regulated in GBM patients,and is strongly correlated with poor prognosis and reduced overall survival.Overexpression of SPHK1 promoted the proliferation,invasion,metastasis,and clonogenicity of GBM cells,while silencing SPHK1 had the opposite effect.SPHK1 promoted inflammation through the NF-κB/IL-6/STAT3 signaling pathway and led to the phosphorylation of JNK,activating the JNK-JUN and JNK-ATF3 pathways and promoting inflammation and proliferation of GBM cells by transcriptional activation of PTX3.SPHK1 interacted with PTX3 and formed a positive feedback loop to reciprocally increase expression,promote inflammation and GBM growth.Inhibition of SPHK1 by the inhibitor,PF543,also decreased tumorigenesis in the U87-MG and U251-MG SPHK1 orthotopic mouse models.In summary,we have characterized the role and molecular mechanisms by which SPHK1 promotes GBM,which may provide opportunities for SPHK1-targeted therapy. | Wan Li Hongqing Cai Liwen Ren Yihui Yang Hong Yang Jinyi Liu Sha Li Yizhi Zhang Xiangjin Zheng Wei Tan Guanhua Du Jinhua Wang | 2022 | Acta Pharmaceutica Sinica B2022，12，12： | 2 |

| 20 | MiR-378a-3p acts as a tumor suppressor in gastric cancer via directly targeting RAB31 and inhibiting the Hedgehog pathway proteins GLI1/2显示文摘Objective:To improve the prognosis of patients with gastric cancer(GC),more effective therapeutic targets are urgently needed.Increasing evidence indicates that miRNAs are involved in the progression of various tumors,and RAS-associated protein in the brain 31(RAB31)is upregulated and promotes the progression of multiple malignant tumors.Here,we focused on identifying RAB31-targeted miRNAs and elucidating their potential mechanism in the progression of GC.Methods:RAB31 and miR-378a-3p expression levels were detected in paired fresh GC tissues and GC cell lines.Bioinformatics analysis was used to predict the miRNAs targeting RAB31 and the relationships between RAB31 and other genes.Dual-luciferase reporter assays were applied to verify the targeted interaction relationship.CCK-8,colony formation,flow cytometry,wound healing,and Transwell assays were performed to assess the proliferation,apoptosis,migration,and invasion of GC cells.Tumorsphere formation assays were performed to assess the stemness of gastric cancer stem cells.Related proteins were detected by Western blot.Xenograft assays in nude mice were performed to explore the effect of miR-378a-3p in vivo.Results:We report the first evidence that miR-378a-3p is downregulated in GC,whereas its overexpression inhibits proliferation,invasion,and migration as well as promotes apoptosis in GC cells.Mechanistically,miR-378a-3p inhibits the progression of GC by directly targeting RAB31.Restoring RAB31 expression partially offsets the inhibitory effect of miR-378a-3p.Further research revealed that miR-378a-3p inhibits GLI1/2 in the Hedgehog signaling pathway and attenuates the stemness of gastric cancer stem cells.Finally,xenograft assays showed that miR-378a-3p inhibits GC tumorigenesis in vivo.Conclusions:MiR-378a-3p inhibits GC progression by directly targeting RAB31 and inhibiting the Hedgehog signaling pathway proteins GLI1/2. | Xinxin Xu Yang Li Guoxiao Liu Kai Li Peng Chen Yunhe Gao Wenquan Liang Hongqing Xi Xinxin Wang Bo Wei Hongtao Li Lin Chen | 2022 | Cancer Biology & Medicine2022，19，12： | 1 |
