| 1 | Parathyroid hormone increases alveolar bone homoeostasis during orthodontic tooth movement in rats with periodontitis via crosstalk between STAT3 and β-catenin显示文摘Periodontitis patients are at risk of alveolar bone loss during orthodontic treatment.The aim of this study was to investigate whether intermittent parathyroid hormone(1–34)treatment(iPTH)could reduce alveolar bone loss during orthodontic tooth movement(OTM)in individuals with periodontitis and the underlying mechanism.A rat model of OTM in the context of periodontitis was established and alveolar bone loss was observed.The control,iPTH and iPTH+stattic groups received injections of vehicle,PTH and vehicle,or PTH and the signal transducer and activator of transcription 3(STAT3)inhibitor stattic,respectively.iPTH prevented alveolar bone loss by enhancing osteogenesis and suppressing bone resorption in the alveolar bone during OTM in rats with periodontitis.This effect of iPTH was along with STAT3 activation and reduced by a local injection of stattic.iPTH promoted osteoblastic differentiation and might further regulate the Wnt/β-catenin pathway in a STAT3-dependent manner.The findings of this study suggest that iPTH might reduce alveolar bone loss during OTM in rats with periodontitis through STAT3/β-catenin crosstalk. | Cheng Zhang Tiancheng Li Chenchen Zhou Li Huang Yuyu Li Han Wang Peipei Duan Shujuan Zou Li Mei | 2020 | International Journal of Oral Science2020，12，4： | 4 |

| 3 | Layered double hydroxides:Scale production and application in soil remediation as super-stable mineralizer显示文摘Soil contamination by heavy metals has presented severe risks to human health through food chain.As one of the most promising remediation technologies,in-situ immobilization strategy has been widely adopted in practice.However,considering the large quantities of contaminated soil,it is still a huge challenge to design low-cost amendments with strong and long-term immobilization ability.Layered double hydroxides(LDHs)have drawn tremendous attention in fundamental research and practical application because of their unique properties.Moreover,owing to its super-stable mineralization effect to heavy metal ions,LDHs have exhibited great potential in the field of soil remediation.In this work,we mainly focused on the scale production strategy of LDHs with low-cost,and its application in soil remediation.Besides,several key challenges in using LDHs as amendments for immobilization of heavy metal ions are presented.We hope that this mini-review could shed light on the sustainable development of LDHs as amendment for heavy metals in future research directions. | Fangqi Mao Peipei Hao Yuquan Zhu Xianggui Kong Xue Duan | 2022 | Chinese Journal of Chemical Engineering2022，35，1： | 2 |

| 7 | Schiff-base silver nanocomplexes formation on natural biopolymer coated mesoporous silica contributed to the improved curative effect on infectious microbes显示文摘Infectious microbes that spread easily in healthcare facilities remain as the severe threat for the public health,especially among immunocompromised populations.Given the intricate problem of dramatic increase in resistance to common biocides,the development of safe and efficient biocide formulated agents to alleviate drug resistance is highly demanding.In this study,Schiff-base ligands were successfully formed on natural biopolymer of epsilon-poly-L-lysine(ε-PL)decorated aldehyde functionalized mesoporous silica SBA-15(CHO-SBA-15)for the selective coordination of silver ions,which was affirmed by various physicochemical methods.Besides the identified broad-spectrum antibacterial activities,the as-prepared Schiff-base silver nanocomplex(CHO-SBA-15/ε-PL/Ag,CLA-1)exhibited an improved inhibitory effect on infectious pathogen growth typified by Escherichia coli and Staphylococcus aureus in comparison with two control silver complexes without Schiff-base conjugates,SBA-15/ε-PL/Ag and CHO-SBA-15/Ag,respectively.In addition,CLA-1 remarkably inhibited the growth of Mycobacterium tuberculosis due to the excellent antimicrobial activity of silver species.Significantly,CLA-1 kills Candida albicans cells,inhibits biofilm formation,and eliminates preformed biofilms,with no development of resistance during continuous serial passaging.The antifungal activity is connected to disruption of bacterial cell membranes and increased levels of intracellular reactive oxygen species.In mouse models of multidrug-resistant C.albicans infection,CLA-1 exhibited efficient in vivo fungicidal efficacy superior to two antifungal drugs,amphotericin B and fluconazole.Moreover,CLA-1 treatment induces negligible toxicity against normal tissues with safety.Therefore,this study reveals the pivotal role of the molecular design of Schiff-base silver nanocomplex formation on biopolymer surface-functionalized silica mesopores as a green and efficient nanoplatform to tackle infectious microbes. | Ling Cai Yanqiang Huang Yuanyuan Duan Qiao Liu Qilan Xu Jia Jia Jianming Wang Qian Tong Peipei Luo Yujie Wen Luming Peng Qian Wu Xudong Hang Huijun Jiang Ping Zhu Yanmei Yang Boshen Zhou Liping Zeng Hongkai Bi Jin Chen | 2021 | Nano Research2021，14，8： | 0 |
| 8 | Chiral self-assembly regulated photon upconversion based on triplet-triplet annihilation显示文摘Photon upconversion(UC)based on triplet-triplet annihilation(TTA)in quasi-solid or solid state has been attracting much research interest due to its great potential applications.To get effective UC,precisely controlled donor-acceptor interaction is vitally important.Chiral self-assembly provides a powerful approach for sophisticated regulation of molecular interaction.Here we report a chiral self-assembly controlled TTA-UC system composed of chiral acceptor and achiral donor.It is found that racemic mixture of acceptors could form straight fibrous nanostructures,which show strong UC emission,while chiral assemblies for homochiral acceptors emit weak upconverted light.The racemic assemblies allow efficient triplet-triplet energy transfer(TTET)and further realize efficient UC emission,while the homochiral assemblies from chiral acceptor produce twisted nanostructures,suppressing efficient triplet energy transfer and annihilation.The establishment of such chiral self-assembly controlled UC system highlights the potential applications of triplet fusion in optoelectronic materials and provides a new perspective for designing highly effective UC systems. | Xujin Qin Jianlei Han Dong Yang Wenjie Chen Tonghan Zhao Xue Jin Peipei Guo Pengfei Duan | 2019 | Chinese Chemical Letters2019，30，11： | 0 |
| 9 | 快重离子辐照在白云母中产生的缺陷形貌和分子振动显示文摘Muscovite mica sheets with a thickness of 12m were irradiated by various kinds of swift heavy ions in Heavy Ion Research Facility in Lanzhou(HIRFL).In the irradiation experiment,the fluence was kept in the range of 1×10^(10)∼1×10^(12) ions/cm^(2),whereas the electronic stopping power Se was in the range from 5.9 to 31.5 keV/nm.The vibrational modifications in irradiated mica were investigated by Fourier-transform infrared(FTIR)spectroscopy and the morphology of the nano-defects on the surface of mica was analyzed by the atomic force microscopy(AFM)in the tapping mode.The infrared spectrum showed that motions from all atomic types in the muscovite mica structure could be found in modes for all vibrations.The intensity of all observed vibrational modes,including the O-H stretching motion at 3621 cm^(−1),was found to decrease with increasing Se values and ion fluences.It was indicated that formation of the defects and structural modifications take place in muscovite mica as a result of swift heavy ion irradiation.And it was found that more defects were introduced in mica by irradiation with higher ion fluences and higher electronic stopping power Se values. | Zhang Shengxia Liu Jie Zengjian Hu Peipei Xu Lijun Li Zongzheng Liu Li Zhai Pengfei Duan Jinglai | 2017 | IMP & HIRFL Annual Report2017，，1： | 0 |
