| 1 | LA-ICP-MS Zircon U-Pb Geochronology of Quartz Porphyry from the Niutougou Gold Deposit in Songxian County,Henan Province显示文摘The Niutougou gold deposit,located in the center of the Xiong'ershan gold district,western Henan Province,is a large gold deposit with many quartz porphyries found in the area.Based on the field geological investigation of quartz porphyry of Niutougou gold deposit and by using the cathodoluminescence(CL) images analysis and in situ LA-ICP-MS U-Pb isotope dating method of zircons,the inner structure,trace element compositions and U-Pb age of the zircons separated from quartz porphyry were analyzed and determined.Cathodoluminescence(CL) images of zircons show clear magmatic zonations.Trace element analyses of zircons reveal that all zircons show high concentrations of Th,U,and HREE,and the REE patterns of depletion in LREE,with a positive Ce anomaly.Zircon LA-ICP-MS U-Pb dating results show that the quartz porphyry in the Niutougou gold deposit was formed at 159.71±0.99 Ma(about 160 Ma),belonging to the product of magmatic activity in late Middle Jurassic.Combined with the geological characteristics of the Niutougou gold deposit,the formation age of the quartz porphyry and the analysis of the formation age of the granite body exposed in the Niutougou gold deposit,the study suggests that the metallogenic epoch of the Niutougou gold deposit may be Yanshanian in age. | WANG Zhongliang GONG Qingjie SUN Xiang WU Fafu WANG Weixing | 2012 | Acta Geologica Sinica(English Edition)2012，86，2： | 17 |

| 3 | Trifolirhizin induces autophagy-dependent apoptosis in colon cancer via AMPK/mTOR signaling显示文摘Dear Editor,Colorectal cancer(CRC)is one of the most frequent diseases with high mortality around the world.Conventional treatments of CRC remain unsatisfactory due to the increasing recurrence rate and adverse reactions including neutropenia,drug resistance,etc.Recently,autophagy has been shown to be involved in regulating cancer development and progression by regulating apoptosis through pro-apoptosis proteins including caspases,in addition to being a potential target for cancer therapeutic intervention.1 Trifolirhizin(Supplementary Fig.S1a)is a natural flavonoid glycosides isolated from Sophora flavescens as well as a bioactive constituent of Xian-Lian-Ke-Li,a commercial traditional Chinese medicine for the cancer prevention.Numerous evidence manifested that trifolirhizin inhibited proliferative activity in melanoma B16 cell,lung cancer H23 cell,human ovarian A2780 cell,and human gastric cancer cell MKN45.2 However,its pharmacological effect and mechanism on CRC remain elusive.Herein,we evaluated the effect of trifolirhizin on autophagy and apoptosis on CRC as well as its related mechanisms,in order to provide evidence to develop a potential agent with less adverse effect in treating CRC. | Dongdong Sun Weiwei Tao Feng Zhang Weixing Shen Jiani Tan Liu Li Qinghai Meng Yugen Chen Ye Yang Haibo Cheng | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 3 |

| 11 | Highly selective detection of copper(Ⅱ) by a “ligand-free” conjugated copolymer in nucleophilic solvents显示文摘The synthesis of N-cyclohexyl carbamate-attached fluorene-alt-phenylene copolymer(PFPNCC)and the use of PFPNCC as a“ligand-free”fluorescent chemosensor for Cu(Ⅱ)are described.Addition of Cu(Ⅱ)can efficiently quench the fluorescence of PFPNCC in nucleophilic solvents such as DMF and DMSO,but not in low nucleophilic solvents such as 1,4-dioxane and THF.Ultraviolet-visible spectra of the mixture of the conjugated polymer and Cu(Ⅱ)indicate the presence of a reduced Cu(Ⅰ)ion in the solution.Furthermore,fluorescence recovery of PFPNCC observed at low temperature suggests that the quenching and reducing mechanism is most probably due to a photo-induced electron transfer from excited PFPNCC to Cu(Ⅱ).Our findings provide a novel strategy for highly selective conjugated polymer-based chemosensors for various target analytes,albeit“ligand-free”. | Weixing Deng Pengfei Sun Quli Fan Lei Zhang Tsuyoshi Minami | 2020 | Frontiers of Chemical Science and Engineering2020，14，1： | 1 |
| 12 | Effect of Aidi injection plus transarterial chemoembolization on primary hepatic carcinoma: a systematic review and Meta-analysis显示文摘OBJECTIVE: To assess the efficacy and safety of Aidi injection plus transarterial chemoembolization(TACE) in patients with primary hepatic carcinoma.METHODS: A comprehensive research of seven electronic databases was performed for comparative studies evaluating Aidi injection combined with TACE for primary hepatic carcinoma until September 2016. Two authors independently extracted data and assessed the methodological quality of the included trials using the Cochrane risk of bias tool from the Cochrane Handbook version 5.1.0. Data was synthesized by using Rev Man 5.3 software.RESULTS: Forty-nine studies involving 3435 patients met the inclusion criteria, most of which were low methodological quality. Compared with TACE alone, Aidi injection plus TACE can significantly improve the efficiency rate [RR = 1.33, 95% CI(1.24, 1.43), P < 0.000 01], clinical beneficial rate[RR = 1.25, 95% CI(1.17, 1.33), P < 0.000 01], survival rate [6 months, RR = 1.19, 95% CI(1.09, 1.29), P <0.0001], 12 months, [RR = 1.37, 95% CI(1.24, 1.52),P < 0.000 01], 18 months, [RR = 2.00, 95% CI(1.26,3.20), P < 0.004], 24 months, [RR = 1.44, 95% CI(1.22, 1.70), P < 0.0001], 36 months, [RR = 1.50, 95%CI(1.07, 2.11), P = 0.02 < 0.05], quality of life [RR =1.84, 95% CI(1.64, 2.05), P < 0.000 01] and immune function [CD3+, MD = 11.12, 95% CI(7.93, 14.30),P < 0.000 01], CD4 +, [MD = 10.37, 95% CI(7.29,13.45), P < 0.000 01], CD4+/CD8+, [MD = 0.30, 95%CI(0.07, 0.53), P = 0.01 < 0.05], NK, [MD = 7.49, 95%CI(6.64, 8.34), P < 0.000 01]. A significant improvement was also found in improvement of symptoms[RR = 1.64, 95%CI(1.38, 1.94), P < 0.000 01], leukopenia [RR = 0.60, 95% CI(0.54, 0.66), P < 0.000 01],thrombocytopenia [RR = 0.46, 95% CI(0.34, 0.61),P < 0.000 01], nausea and vomiting incidence [RR =0.66, 95% CI(0.54, 0.81), P < 0.0001), liver damage rate [RR = 0.57, 95% CI(0.42, 0.77), P = 0.0003 <0.05), and kidney damage rate [RR = 0.18, 95% CI(0.05, 0.68), P = 0.01 < 0.05].CONCLUSION: The results suggested that Aidi injection plus TACE significantly improve the clinical effect of TACE, and reduce the incidence of adverse events. However, rigorous multicenter trials with larger size are warranted to further confirm the findings. | Shen Zhengjie Gu Wenzhe Cheng Haibo Shen Weixing Sun Dongdong Zeng Yun Tao Lihuiping Wu Mianhua | 2017 | Journal of Traditional Chinese Medicine2017，37，5： | 1 |

| 14 | The novel peptide Nb PPI1 identified from Nicotiana benthamiana triggers immune responses and enhances resistance against Phytophthora pathogens显示文摘In plants, recognition of small secreted peptides, such as damage/danger-associated molecular patterns(DAMPs), regulates diverse processes,includingstressandimmune responses. Here, we identified an SGPS(Ser-Gly-Pro-Ser) motif-containing peptide, Nicotiana tabacum NtPROPPI, and its two homologs in Nicotiana benthamiana, NbPROPPI1 and NbPROPPI2. Phytophthora parasitica infection and salicylic acid(SA) treatment induced NbPROPPI1/2 expression. Moreover, SignalP predicted that the 89-amino acid NtPROPPI includes a 24-amino acid N-terminal signal peptide and NbPROPPI1/2-GFP fusion proteins were mainly localized to the periplasm. Transient expression of NbPROPPI1/2 inhibited P.parasiticacolonization,andNbPROPPI1/2 knockdown rendered plants more susceptible to P. parasitica. An eight-amino-acid segment in the NbPROPPI1 C-terminus was essential for its immune function and a synthetic 20-residue peptide, NbPPI1, derived from the C-terminus of NbPROPPI1 provoked significant immune responses in N. benthamiana. These responses led to enhanced accumulation of reactive oxygen species, activation of mitogen-activated protein kinases, and up-regulation of the defense genes Flg22-induced receptor-like kinase(FRK) and WRKY DNA-binding protein 33(WRKY33). The NbPPI1-induced defense responses require Brassinosteroid insensitive1-associated receptor kinase 1(BAK1). These results suggest that NbPPI1 functions as a DAMP in N. benthamiana;this novel DAMP provides a potentially useful target for improving plant resistance to Pytophthora pathogens. | Qujiang Wen Manli Sun Xianglan Kong Yang Yang Qiang Zhang Guiyan Huang Wenqin Lu Wanyue Li Yuling Meng Weixing Shan | 2021 | Journal of Integrative Plant Biology2021，63，5： | 1 |
| 15 | Comprehensive Control Scheme for an Interlinking Converter in a Hybrid AC/DC Microgrid显示文摘This paper presents a comprehensive control scheme for the interlinking converter(ILC)in a hybrid AC/DC microgrid consisting of the outer loop flexible power sharing control and the improved robust inner loop control.The outer loop power control of ILC is presented to achieve flexible power sharing of distributed generations(DGs)in the hybrid microgrid,depending on different power management objectives,which is realized based on the deduced balance state equation,and regulating the frequency and DC voltage at the same time.The improved robust inner loop control of ILC is also presented to suppress external disturbance and system model uncertainties with the improved dynamic response.This improved inner loop control which includes a disturbance observer link,can force the converter current to track the reference value with no steady error and improve the dynamic stability of the microgrid・With the proposed outer loop power sharing control and improved inner loop control,the comprehensive control scheme for the ILC is presented・Simulations cases show the effectiveness and superiority of the proposed comprehensive control scheme. | Ziwen Liu Shihong Miao Weixing Wang Dandan Sun | 2021 | CSEE Journal of Power and Energy Systems2021，7，4： | 1 |
| 16 | Synthesis, Characterization and Application of A Novel Carbon Bridged Half-metallocene Chromium Catalyst for Methyl Methacrylate Polymerization显示文摘A new carbon bridged cyclopentadienyl chromium complex of the type [(C5H4)C(CH3)2 CH2(C5H4N)]CrCl2 was prepared by treatment of CrCl3·(THF)3 in THF solution with the lithium salt of ligand containing cyclopentadienyl and pyridyl groups. The chromium complex was characterized by 1H NMR and elemental analysis(EA), and the crystal structure was determined by X-ray diffraction analysis. Activated by Al(i-Bu)3, the chromium complex displayed a very high activity for methyl methacrylate(MMA) polymerization. After 24 hours,more than 95.5% MMA was converted to polymethyl methacrylate(PMMA) with a viscosity average molecular weight(Wη) of 416000 g·mol-1 at 60 ℃ for MMA/ Al(i-Bu)3 /chromium catalyst molar ratio of up to 2000:20:1. Effects of temperature, molar ratios of MMA/catalyst and catalyst/cocatalyst on the polymerization have been studied. The high conversion of MMA and high molecular weight of PMMA with narrow molecular weight distribution is caused by the unique stable active site formed by the new chromium complex and aluminum cocatalyst. | 程正载 GONG Kai WANG Yang ZHOU Xue ZHANG Weixing LI Yin SUN Junquan LI Wenbing | 2014 | Journal of Wuhan University of Technology(Materials Science)2014，29，6： | 1 |
