| 3 | Cell-Mediated Immunity Imbalance in Patients with Intrahepatic Cholestasis of Pregnancy显示文摘Decidual lymphocytes may mediate fetal trophoblast recognition and regulate maternal immune reaction and play an essential role in the maintenance of normal pregnancy. The aim of this study was to compare the percentage of T cells, natural killer (NK) cells and natural killer T (NKT) cells within decidual parietalis of normal pregnant controls (NP) and patients with intraheptic cholestasis of pregnancy (ICP), and to investigate the production of interleukin-4 (IL-4), interferon-γ (IFN-γ) in the culture supernatant of decidual parietalis mononuclear cells (DPMCs). Compared with controls, the decidua parietalis from ICP were characterized with significant increased percentages of CD3-CD56+ cells, CD3+CD56+ cells, CD56+CD16+ cells, CD56+CD16- cells, CD56+NKG2D+ cells, and the significant decreased percentages of CD3+ cells, CD3+CD4+ cells. There were no differences found for the percentage of CD3+CD8+ cells, CD56+NKG2A+ cells between control and study group. In addition, the enhanced concentration of IFN-γ was presented in culture supernatant of DPMCs from ICP. It was suggested that the increased NK cells, NKT cells and the decreased T cells in the decidual parietalis and over-secretion of IFN-γ could be correlated with the pathophysiology of ICP patients. | Bin Ling Fengqiu Yao Ying Zhou Zhengzheng Chen Guodong Shen Yuanyuan Zhu | 2007 | Cellular & Molecular Immunology2007，4，1： | 19 |
| 4 | Effect of hierarchical ZSM-5zeolite crystal size on diffusion and catalytic performance of n-heptane cracking显示文摘Hierarchical ZSM-5zeolite aggregates with different sizes of nanocrystals were synthesized using different amounts of the mesoporogen 3-aminopropyl- triethoxysilane.The effect of the crystal size on the catalytic cracking of n-heptane was investigated and the Thiele modulus and effectiveness factor were used to determine the reaction rate-limiting step.The crystal size affected the textual properties of the catalysts but not the acidic properties of the catalysts.The reaction rate was first order with respect to the n-heptane concentration.Cracking over hierarchical zeolites with nanocrystal sizes larger than about 50nm took place under transition-limiting conditions,whereas the reaction over hierarchical zeolites with nanocrystal sizes of 15 or 30nm proceeded under reaction control conditions.Hierarchical ZSM-5 zeolite aggregates with smaller nanocrystals had better selectivity for light olefins which can be ascribed to the shorter diffusion path lengths and lower diffusion resistance in these catalysts. Furthermore,these catalysts had lower coking levels which can be attributed to the substantial number of mesopores which prevent the formation of coke precursors. | Shuman Xu Xiaoxiao Zhang Dangguo Cheng Fengqiu Chen Xiaohong Ren | 2018 | Frontiers of Chemical Science and Engineering2018，12，4： | 10 |
| 5 | Local icariin application enhanced periodontal tissue regeneration and relieved local inflammation in a minipig model of periodontitis显示文摘Periodontitis is an inflammatory autoimmune disease. Treatment should alleviate inflammation, regulate the immune reaction and promote periodontal tissue regeneration. Icariin is the main active ingredient of Epimedii Folium, and it is a promising compound for the enhancement of mesenchymal stem cell function, promotion of bone formation, inhibition of bone resorption, alleviation of inflammation and regulation of immunity. The study investigated the effect of icariin on periodontal tissue regeneration in a minipig model of periodontitis. The minipig model of periodontitis was established. Icariin was injected locally. The periodontal clinical assessment index, a computed tomography(CT) scan, histopathology and enzyme-linked immune sorbent assay(ELISA)were used to evaluate the effects of icariin. Quantitative analysis results 12 weeks post-injection demonstrated that probing depth,gingival recession, attachment loss and alveolar bone regeneration values were(3.72 ± 1.18) mm vs.(6.56 ± 1.47) mm,(1.67 ± 0.59)mm vs.(2.38 ± 0.61) mm,(5.56 ± 1.29) mm vs.(8.61 ± 1.72) mm, and(25.65 ± 5.13) mm3 vs.(9.48 ± 1.78) mm3 in the icariin group and0.9% NaCl group, respectively. The clinical assessment, CT scan, and histopathology results demonstrated significant enhancement of periodontal tissue regeneration in the icariin group compared to the 0.9% NaCl group. The ELISA results suggested that the concentration of interleukin-1 beta(IL-1β) in the icariin group was downregulated compared to the 0.9% NaCl group, which indicates that local injection of icariin relieved local inflammation in a minipig model of periodontitis. Local injection of icariin promoted periodontal tissue regeneration and exerted anti-inflammatory and immunomodulatory function. These results support the application of icariin for the clinical treatment of periodontitis. | Xiuli Zhang Nannan Han Guoqing Li Haoqing Yang Yangyang Cao Zhipeng Fan Fengqiu Zhang | 2018 | International Journal of Oral Science2018，10，3： | 9 |

| 7 | A density functional theory study on the decomposition of aliphatic hydrocarbons and cycloalkanes during coal pyrolysis in hydrogen plasma显示文摘To get deep understanding of the reaction mechanism of coal pyrolysis in hydrogen plasma, the decomposition reaction pathways of aliphatic hydrocarbons and cycloalkanes, which are two main components in volatiles from coal, were investigated. Methane and cyclohexane were chosen as the model compounds. Density functional theory was employed, and many reaction pathways were involved. Calculations were carried out in Gaussian 09 at the B3LYP/6-31G(d,p) level of the theory. The results indicate that the main pyrolysis products of methane and cyclohexane in hydrogen plasma are both hydrogen and acetylene, and the participation of active hydrogen atoms makes dehydrogenation reactions more favorable. H2 mainly comes from dehydrogenation process, while many reaction pathways are responsible for acetylene formation. During coal pyrolysis in hydrogen plasma, three main components in volatiles like aliphatic hydrocarbons, cycloalkanes and aromatic hydrocarbons lead to the formation of hydrogen and acetylene, but their contributions to products distribution are different. | Xiaoyuan Huang Dangguo Cheng Fengqiu Chen Xiaoli Zhan | 2015 | Journal of Energy Chemistry2015，24，1： | 5 |
| 8 | Ultrafast Stretched-Pulse Fiber Laser Mode-Locked by Carbon Nanotubes显示文摘Ultrafast fiber sources having short pulses, broad bandwidth, high energy, and low amplitude fluctuations have widespread applications. Stretched-pulse fiber lasers, incorporating segments of normal and anomalous dispersion fibers, are a preferred means to generate such pulses. We realize a stretched-pulse fiber laser based on a nanotube saturable absorber, with 113 fs pulses, 33.5 nm spectral width and ~0.07% amplitude fluctuation, outperforming current nanotube-based designs. | Zhipei Sun Tawfique Hasan Fengqiu Wang Aleksey G.Rozhin Ian H.White Andrea C.Ferrari | 2010 | Nano Research2010，3，6： | 4 |
| 9 | Studies on the structure and catalytic performance of S and P promoted Na-W-Mn-Zr/SiO_2 catalyst for oxidative coupling of methane显示文摘A series of Na-W-Mn-Zr/SiO2 catalysts promoted by different contents of S or/and P were prepared and their catalytic performance for oxidative coupling of methane was investigated to clarify the effect of S and P on the Na-W-Mn-Zr/SiO2 catalyst. The catalysts were characterized by X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). From the characterization results, it is found that the addition of S and P to the Na-W-Mn-Zr/SiO2 catalyst helps the formation of active phases, such as α-cristobalite, Na2WO4, ZrO2, and Na2SO4. Moreover, the addition of S and P increases the concentration of surface-active oxygen species by improving the migration of active components from the bulk phase to the surface of the catalyst. According to the activity test, impressive methane conversion and C2 hydrocarbons yield were obtained at a low temperature of 1023 K over the six-component Na-W-Mn-Zr-S-P/SiO2 catalyst, which contained 2 wt% S and 0.4 wt% P simultaneously. The deactivation of Na-W-Mn-Zr-S-P/SiO2 was due to the loss of surface active components. | Wen Zheng, Dangguo Cheng, Ning Zhu, Fengqiu Chen, Xiaoli Zhan Department of Chemical and Biochemical Engineering, Zhejiang University, Hangzhou 310027, Zhejiang, China | 2010 | Journal of Natural Gas Chemistry2010，19，1： | 4 |
| 10 | Aluminum impregnated silica catalyst for Friedel–Crafts reaction:Influence of ordering mesostructure显示文摘Friedel–Crafts alkylation of benzene with linear chain ole fin(C_(10)–C_(14)),which is an important reaction of synthetic detergent,was studied via different catalysts of aluminum impregnated silica molecular sieves.AlCl_3 was immobilized on silica molecular sieves with different channel structures,hexagonal packing channels network(SBA-15,MCM-41),and disordered channel network(SiO_2,SiO_2-Gel) by impregnation.XRD and N_2 adsorption–desorption isotherms con firmed that the speci fic mesoporous structures were maintained for order channel network catalyst after impregnation.Catalytic activities were investigated under different conditions.The in fluences of channel structure were discussed.The results showed that catalyst based on mesoporous like SBA-15 had the highest catalytic activities and 2-LAB selectivity compared with other catalysts in this work.The highest 2-LAB selectivity was nearly 50% when 1-dodecene conversion was nearly 100%.At low 1-dodecene conversion or higher benzene/1-dodecene molar ratio,2-LAB selectivity was nearly 60%. | Yibo He Qinghua Zhang Xiaoli Zhan Dangguo Cheng Fengqiu Chen | 2017 | Chinese Journal of Chemical Engineering2017，25，10： | 3 |

| 15 | Synthesis and characterization of caprolactone based polyurethane with degradable and antifouling performance显示文摘In this work,a degradable polyurethane composed of caprolactone(CL)and L-Lactide(LLA)as soft segments,and 4,40-methylenebis(cyclohexyl isocyanate)(H12 MDI)and polytetramethylene ether glycol(PTMEG)as hard segments,was prepared.Hydrolytic degradation experiment revealed that the degradable polyurethane(PU)could be degraded in artificial seawater.It also showed that caprolactone-copolyurethane(CL-PU)copolymer with higher crystallinity degraded much slower in artificial seawater.However,the introduction of LLA resulted in an increase in the hydrophilicity and reduction in the crystallinity of degradable PU,as demonstrated by the contact angle analysis.The result of the scanning electron microscope showed that the surface of degradable PU renewed under static condition.Moreover,degradable PU was able to be used as a carrier,and it controlled the release rate of 4,5-dichloro-2-octyl-isothiazolone(DCOIT).The anti-diatom(Navicula incerta)test demonstrated that the(caprolactone-co-L-lactide)-co-polyurethane 4(CL/LAx-PU4)with DCOIT contents prevented the adhesion of diatom Navicula incerta(88.37%reduction)due to their self-polishing and the release of antifoulants.Therefore,the degradable PU consisted of CL,LLA,and DCOIT could be a durable resin with good antifouling activity for the application in the marine anti-biofouling field. | Abid Ali Lina Song Jiankun Hu Jingxian Jiang Qingqing Rao Muhammad Shoaib Shah Fahad Yongjie Cai Xiaoli Zhan Fengqiu Chen Qinghua Zhang | 2021 | Chinese Journal of Chemical Engineering2021，34，6： | 2 |

| 19 | Dealumination kinetics of composite ZSM-5/mordenite zeolite during steam treatment: An in-situ DRIFTS study显示文摘To get a better understanding of structural deactivation of ZSM-5/MOR during the catalytic cracking of n-heptane in the steam atmosphere, a comprehensive mechanism of hydrothermal dealumination was proposed through in-situ diffuse reflectance Fourier transform infrared spectroscopy(DRIFTS) in this work. The mechanism can be divided into two steps: firstly, the hydrolysis of four Al\\O bonds, and secondly, the self-healing of Si\\OH bonds accompanied with partial condensation of the extra-framework Al species. Accordingly, the kinetics of dealumination process has also been fully discussed. In the IR spectra, the range of 3450–3850 cm^(-1) could be deconvolved to distinguish the hydroxyl groups on the different position and calculate the consumption of each hydroxyl group during the reaction. Based on results from the in-situ DRIFTS, the kinetics of dealumination was hence developed and also in well agreement with the kinetics of deactivation of ZSM/MOR catalysts during the reaction in the presence of little coke deposits. | Xiaoxiao Zhang Dangguo Cheng Fengqiu Chen Xiaoli Zhan | 2018 | Chinese Journal of Chemical Engineering2018，26，3： | 1 |
| 20 | Characterization and catalytic behavior of Na-W-Mn-Zr-S-P/SiO_2 prepared by different methods in oxidative coupling of methane显示文摘Na-W-Mn-Zr-S-P/SiO2 catalysts for oxidative coupling of methane (OCM) were prepared by incipient wetness impregnation, sol-gel and mixture slurry methods. The catalyst prepared by mixture slurry method showed the best catalytic performance among all samples. In addition, the effects of different addition sequences of Na, W, Mn, Zr, S and P on the catalytic performance were studied. The absence of Na before the addition of Mn and Zr in the catalysts preparation depressed the formation of the active phases of Mn2O3 and ZrO2 and decreased the activities of the catalysts significantly. | Wen Zheng Dangguo Cheng Fengqiu Chen Xiaoli Zhan | 2010 | Journal of Natural Gas Chemistry2010，19，5： | 1 |
