1Clinical features and treatment status of hemifacial spasm in China显示文摘Wang Lin Hu Xingyue Dong Hongjuan Wang Wenzhao Huang Yue Jin Lingjing Luo Yumin Zhang Weixi Lian Yajun Liang Zhanhua Shang Huifang Feng Yabo wu Yiwen Chen Jun Luo Weifeng Wan Xinhua 2014Chinese Medical Journal2014,,5:20
2Anti-inflammatory and anti-thrombogenic effects of atorvastatin in acute ischemic stroke显示文摘Atorvastatin decreases inflammation and thrombogenesis in patients with carotid artery plaque. Atorvastatin is administered to lower lipid levels, but its anti-inflammatory and anti-thrombogenic effects remain unclear. Eighty-nine patients from northeastern China with acute ischemic stroke caused by large-artery atherosclerosis were randomly divided into the study and control groups. All patients received routine treatment, including antiplatelet therapy, circulatory support, and symp-tomatic treatment. The study group (n=43) also received daily atorvastatin 20 mg/d, and the control group (n=46) received daily placebo pills containing glucose. After 4 weeks, the levels of C-reactive protein, fibrinogen, and D-dimer were significantly lower in the study group than in the control group. Decreases in the levels of C-reactive protein, fibrinogen, and D-dimer were not associated with de-creases in the levels of triacylglycerol and low-density lipoprotein cholesterol. These results suggest that atorvastatin reduces inflammation and thrombogenesis independent of its lipid-lowering effects in patients with acute ischemic stroke caused by large-artery atherosclerosis.Lianqiu Min Shuai Shao Xiaoning Wu Lin Cong Ping Liu Haiping Zhao Yumin Luo 2013Neural Regeneration Research2013,8,23:19
3Wogonoside inhibits tumor growth and metastasis in endometrial cancer via ER stress-Hippo signaling axis显示文摘Wogonoside,a bioactive flavonoid component derived from Scutellaria baicalensis Georgi,has been reported to inhibit tumor growth in mice bearing various types of cancer cells such as breast cancer,lung cancer,and leukemia cells.However,whether wogonoside could inhibit tumor growth of endometrial cancer has not been elucidated.In this study,we explored the function of wogonoside on tumor growth and the underlying mechanism on endometrial cancer.Firstly,we investigated the effect of wogonoside on endometrial cancer cells and found that wogonoside could significantly decrease cell proliferation and metastasis.Mechanistically,wogonoside could aggravate the extent of ER stress and upregulate the phosphorylation level of Mammalian Ste20-like kinase 1,leading to the activation of the Hippo signaling pathway.Taken together,in vitro and in vivo data demonstrated that wogonoside could be a potent inducer of ER stress and could be further developed into a promising therapy for endometrial cancer.Shaorong Chen Zhuna Wu Yumin Ke Pingping Shu Caihong Chen Ruying Lin Qirong Shi 2019Acta Biochimica et Biophysica Sinica2019,51,11:8
4Distinct beneficial effect of Sn on the corrosion resistance of Cr-Mo low alloy steel显示文摘In this work,the beneficial effect of Sn addition on the corrosion resistance mechanism of Cr-Mo low alloy steel was studied.Results demonstrated that Sn improves the corrosion resistance of the steel matrix mainly by influencing the microstructural transformation.Sn addition and the synergistic effect of Sn,Cr,and Mo promote the formation of α-FeOOH,SnO_(2),SnO,Cr(OH)_(3),and molybdates,lead to the improved protection and stability of the rust layer.This synergistic effect also endows the inner rust layer with cation selectivity,preventing the further penetration of Cl-and inhibiting the localized corrosion of steel.Meihui Sun Xiaojia Yang Cuiwei Du Zhiyong Liu Yong Li Yumin Wu Hongyu San Xiandong Su Xiaogang Li 2021Journal of Materials Science & Technology2021,,22:6
5An interpolating boundary element-free method (IBEFM) for elasticity problems显示文摘The paper begins by discussing the interpolating moving least-squares (IMLS) method. Then the formulae of the IMLS method obtained by Lancaster are revised. On the basis of the boundary element-free method (BEFM), combining the boundary integral equation method with the IMLS method improved in this paper, the interpolating boundary element-free method (IBEFM) for two-dimensional elasticity problems is presented, and the corresponding formulae of the IBEFM for two-dimensional elasticity problems are obtained. In the IMLS method in this paper, the shape function satisfies the property of Kronecker δ function, and then in the IBEFM the boundary conditions can be applied directly and easily. The IBEFM is a direct meshless boundary integral equation method in which the basic unknown quantity is the real solution to the nodal variables. Thus it gives a greater computational precision. Numerical examples are presented to demonstrate the method.REN HongPing 1 , CHENG YuMin 2 & ZHANG Wu 1 1 School of Computer Engineering and Science, Shanghai University, Shanghai 200072, China 2 Shanghai Institute of Applied Mathematics and Mechanics, Shanghai University, Shanghai 200072, China 2010Science China(Physics,Mechanics & Astronomy)2010,53,4:5
6Biocompatibility studies of silk fibroin-based artificial nerve grafts in vitro and in vivo显示文摘Silk fibroin(SF)has been used extensively in the biomedical field including tissue engineering for the generation of artificial bones,skins or ligaments.We have previously reported on good in vitro biocompatibility of SF fibers with peripheral nerve tissues and cells.In the present study,we developed a novel design of the SF-based artificial nerve graft(SF graft)which was composed of a SF-nerve guidance conduit(NGC)inserted with SF fibers.MTT assay was performed to determine the cytotoxicity of the SF-NGC extract fluid on the cultured L929 cells derived from an immortalized mouse fibroblast cell line.In addition,this SF graft was implanted into adult rats for bridging a 10-mm long sciatic nerve defect.The following-up experiments at initial stage(1-4 week)of nerve regeneration including routine blood tests and histochemical investigation were conducted to evaluate the in vivo biocompatibility of the SF graft with peripheral nerves.The results demonstrated that the SF-NGC graft was biocompatible with the surrounding tissues and cells due to its low inflammatory potential with a grade 0 under the U.S.Pharmacopeia guidelines and it was generally suitable to a certain degree for bridging peripheral nerve defects in virtue of supporting Schwann cell adherence,expansion and migration.Therefore the SF graft is a promising alternative to classical autografts for peripheral nerve repair.Chen Xuemei Yang Yumin Wu Jian Zhao Yahong Ding Fei Gu Xiaosong 2007Progress in Natural Science:Materials International2007,17,9:5
7Injectable dual glucose-responsive hydrogel-micelle composite for mimicking physiological basal and prandial insulin delivery显示文摘For type 1 and advanced type 2 diabetic patients, insulin replacement therapy with simulating on-demand prandial and basal insulin secretion is the best option for optimal glycemic control. However, there is no insulin delivery system yet could mimic both controlled basal insulin release and rapid prandial insulin release in response to real-time blood glucose changes. Here we reported an artificial insulin delivery system, mimicking physiological basal and prandial insulin secretion, to achieve real-time glycemic control and reduce risk of hypoglycemia. A phenylboronic acid(PBA)/galactosyl-based glucose-responsive insulin delivery system was prepared with insulin-loaded micelles embedded in hydrogel matrix. At the hyperglycemic state, both the hydrogel and micelles could swell and achieve rapid glucose-responsive release of insulin, mimicking prandial insulin secretion.When the glucose level returned to the normal state, only the micelles partially responded to glucose and still released insulin gradually. The hydrogel with increased crosslinking density could slow down the diffusion speed of insulin inside, resulting in controlled release of insulin and simulating physiological basal insulin secretion. This hydrogel-micelle composite insulin delivery system could quickly reduce the blood glucose level in a mouse model of type 1 diabetes, and maintain normal blood glucose level without hypoglycemia for about 24 h. This kind of glucose-responsive hydrogel-micelle composite may be a promising candidate for delivery of insulin in the treatment of diabetes.Juan Lv Gang Wu Ying Liu Chang Li Fan Huang Yumin Zhang Jinjian Liu Yingli An Rujiang Ma Linqi Shi 2019Science China Chemistry2019,62,5:5
8Loss of Wip1 aggravates brain injury after ischaemia/reperfusion by overactivating microglia显示文摘Background and purpose The inflammatory response mediated by microglia/macrophages is closely related to cerebral ischaemia/reperfusion injury.Wild-type p53-induced protein phosphatase 1(Wip1),a serine/threonine phosphatase,is expressed in various tissues.A growing number of reports have suggested that Wip1 is a negative regulator of inflammation in peripheral tissue;however,its role in the central nervous system(CNS)remains unclear.This study aimed to clarify whether Wip1 can inhibit CNS inflammation by regulating microglia/macrophage functions after ischaemic injury.Methods A model of middle cerebral artery occlusion and reperfusion was established in mice.CNS inflammation was simulated by lipopolysaccharide treatment of primary microglia.Laser speckle imaging was used to monitor regional cerebral blood flow.Behavioural outcomes were assessed with a TreadScan gait analysis system.TTC staining was used to evaluate the infarct volume,and western blotting and immunofluorescence staining were applied to detect the phenotypical transformation of microglia.ELISA was performed to detect the levels of inflammatory factors.Results Wip1 expression was increased after ischaemia/reperfusion.Wip1-knockout(KO)mice displayed more severe brain injury than wild-type mice,as indicated by aggravated motor dysfunction,greater brain infarct volumes and higher expression of inflammatory cytokines(interleukin-6 and tumour necrosis factor alpha)in the brain.We also found that Wip1 depletion increased microglial/macrophage activation in both in vitro and in vivo models,which all showed activation of microglia/macrophages.Lentivirus-Ppm1d reversed the injury induced by Wip1-KO.Conclusions Our results suggest that Wip1 may inhibit neuroinflammation by inhibiting microglial/macrophage activation after brain ischaemia/reperfusion injury.Feng Yan Xiang Cheng Ming Zhao Shenghui Gong Ying Han Liping Ding Di Wu Yumin Luo Wei Zuo Lingling Zhu Ming Fan Xunming Ji 2021Stroke & Vascular Neurology2021,6,3:4
9All-dielectric three-element transmissive Huygens’ metasurface performing anomalous refraction显示文摘Metasurfaces have pioneered a new avenue for advanced wave-front engineering.Among the various types of metasurfaces,Huygens'metasurfaces are thought to be a novel paradigm for flat optical devices.Enabled by spectrally overlapped electric resonance and magnetic resonance,Huygens'metasurfaces are imparted with high transmission and full phase coverage of 2π,which makes them capable of realizing high-efficiency wave-front control.However,a defect of Huygens'metasurfaces is that their phase profiles and transmissive responses are often sensitive to the interaction of neighboring Huygens'elements.Consequently,the original assigned phase distribution can be distorted.In this work,we present our design strategy of transmissive Huygens'metasurfaces performing anomalous refraction.We illustrate the investigation of Huygens'elements,realizing the overlapping between an electric dipole and magnetic dipole resonance based on cross-shaped structures.We find that the traditional discrete equidistant-phase design method is not enough to realize a transmissive Huygens'surface due to the interaction between neighboring Huygens'elements.Therefore,we introduce an extra optimization process on the element spacing to palliate the phase distortion resulting from the element interaction.Based on this method,we successfully design unequally spaced three-element transmissive metasurfaces exhibiting anomalous refraction effect.The anomalous refractive angle of the designed Huygens'metasurface is 30°,which exceeds the angles of most present transmissive Huygens'metasurfaces.A transmissive efficiency of 83.5%is numerically derived at the operating wavelength.The far-field electric distribution shows that about 93%of transmissive light is directed along the 30°refractive direction.The deflection angle can be tuned by adjusting the number of Huygens'elements in one metasurface unit cell.The design strategies used in this paper can be inspiring for other functional Huygens'metasurface schemes.CHANG LIU LEI CHEN TIESHENG WU YUMIN LIU JING LI YU WANG ZHONGYUAN YU HAN YE LI YU 2019Photonics Research2019,7,12:3
10High-efficiency all-dielectric transmission metasurface for linearly polarized light in the visible region显示文摘We propose and numerically investigate an efficient transmission-mode metasurface that consists of quasicontinuous trapezoid-shaped crystalline silicon nanoantennas on a quartz substrate. This metasurface provides a linear phase gradient and realizes both full 2π phase shift and high transmission efficiency in the operating wavelength range from 740 to 780 nm. At the central wavelength around 751 nm, the total transmission efficiency is up to 88.0% and the section of the desired anomalous refraction is 80.4%. The anomalous refraction angle is 29.62°, and larger refraction angle can be achieved by changing the period of the super cell. We demonstrate a refraction angle as large as 38.59°, and the anomalous transmission efficiency reaches 76.6% at wavelength of 741 nm. It is worth mentioning that the structure is much simpler than conventional metasurfaces based on arrays of discrete nanoantennas. Our research may pave the way for designing efficient all-dielectric phase-gradient metasurfaces and applying them in integrated optical devices for wavefront control.LIU YANG DONG WU YUMIN LIU CHANG LIU ZENGHUI XU HUI LI ZHONGYUAN YU LI YU RAN YE 2018Photonics Research2018,6,6:2
11Engineering of dendritic dopant-free hole transport molecules:enabling ultrahigh fill factor in perovskite solar cells with optimized dendron construction显示文摘Developing dopant-free hole-transporting materials(HTMs)for high-performance perovskite solar cells(PVSCs)has been a very active research topic in recent years since HTMs play a critical role in optimizing interfacial charge carrier kinetics and in turn determining device performance.Here,a novel dendritic engineering strategy is first utilized to design HTMs with a D-A type molecular framework,and diphenylamine and/or carbazole is selected as the building block for constructing dendrons.All HTMs show good thermal stability and excellent film morphology,and the key optoelectronic properties could be fine-tuned by varying the dendron structure.Among them,MPA-Cz-BTI and MCz-Cz-BTI exhibit an improved interfacial contact with the perovskite active layer,and non-radiative recombination loss and charge transport loss can be effectively suppressed.Consequently,high power conversion efficiencies(PCEs)of 20.8%and 21.35%are achieved for MPA-Cz-BTI and MCz-Cz-BTI based devices,respectively,accompanied by excellent long-term storage stability.More encouragingly,ultrahigh fill factors of 85.2%and 83.5%are recorded for both devices,which are among the highest values reported to date.This work demonstrates the great potential of dendritic materials as a new type of dopant-free HTMs for high-performance PVSCs with excellent FF.Wei Chen Yang Wang Bin Liu Yajun Gao Ziang Wu Yongqiang Shi Yumin Tang Kun Yang Yujie Zhang Weipeng Sun Xiyuan Feng Frédéric Laquai Han Young Woo Aleksandra B.Djurisic Xugang Guo Zhubing He 2021Science China Chemistry2021,64,1:2
12Cephalopods-inspired Repairable MWCNTs/PDMS Conductive Elastomers for Sensitive Strain Sensor显示文摘Flexible electronic devices based on reversible bonds for self-curing capabilities arouses extensive interest.However,most of the composite conductive elastomers have the problems of poor mechanical properties and slow recovery of mechanical properties during multiple stretching,which hinder their stability in continuous operation.In this study,hyperbranched-MWCNTs/hyperbranched-PDMS self-healable conductive elastomers inspired by cephalopods were successfully developed.The prepared conductive elastomer exhibited good self-healing ability(91%)at room temperature excited by multiple reversible interactions.The prepared elastomer showed outstanding mechanical properties and anti-fatigue ability,so that it can cope with more arduous tasks.Moreover,the elastomer was sensitive to the change of stress states and can be used as a stable strain sensor.Therefore,the self-repairing conductive elastomer has potential practicability in the fields of human-computer interaction,motion monitoring,soft robot and so on.Kaiming Zhang Zhe Wang Yuetao Liu Haoyu Zhao Chuanhui Gao Yumin Wu 2022Chinese Journal of Polymer Science2022,40,4:2
13Bulk growth and separation of single-walled carbon nanotubes from rhenium catalyst显示文摘Bulk synthesis of single-walled carbon nanotubes(SWNTs)using solid catalyst has been challenging,despite of recent breakthrough in the chirality-specific growth on the flat substrate surface.In this work,we propose a porous magnesia support rhenium catalyst for bulk synthesis of SWNTs.It is found that the well-dispersed catalyst with a high melting point and the optimal chemical vapor deposition reaction conditions account for the growth of SWNTs.Detailed characterizations reveal the produced SWNTs are dominant in(n,n−1)and(n,n−2)species.Furthermore,by using a multicolumn chromatography post-growth separation method,SWNTs with three defined diameter ranges were obtained.This work guides the design of porous oxide supported catalyst for bulk synthesis and diameter-dependent sorting of SWNTs,which will ultimately help harness the extraordinary properties of SWNTs.Chen Ma Yumin Liu Lili Zhang Liu Qian Yiming Zhao Ying Tian Qianru Wu Dong Li Nan Zhao Xueting Zhang Liantao Xin Huaping Liu Pengxiang Hou Chang Liu Maoshuai He Jin Zhang 2022Nano Research2022,15,7:2

15A ratiometric near-infrared naphthalimide-based fluorescent probe with high sensitivity for detecting Fe^(2+)in vivo显示文摘Iron is one of the essential trace elements in the human body.It plays an important role in human biology and pathology.Deregulation of iron levels in cells is associated with disease development.In this work,we synthesized a novel near-infrared intramolecular charge transfer(ICT)based ratiometric fluorescent probe to detect Fe^(2+),by using naphthalimide and indole moieties as building blocks.Our work showed that the radiometric probe has excellent selectivity,sensitivity and rapid response.Moreover,we could successfully perform real-time monitoring of Fe^(2+) in He La cells and C.elegans.Lina Huang Yu Chen Yuqiang Zhao Yumin Wang Junwei Xiong Junfeng Zhang Xianghua Wu Ying Zhou 2020Chinese Chemical Letters2020,31,11:2
16Ubiquitin-specific protease 24 promotes EV71 infection by restricting K63-linked polyubiquitination of TBK1显示文摘TANK-binding kinase 1(TBK1)is an essential protein kinase for activation of interferon regulatory factor 3(IRF3)and induction of the type I interferons(IFN-I).Although the biochemical regulation of TBK1 activation has been studied,little is known about how enterovirus 71(EV71)employs the deubiquitinases(DUBs)to regulate TBK1 activation for viral immune evasion.Here,we found that EV71 infection upregulated the expression of ubiquitinspecific protease 24(USP24).Further studies revealed that USP24 physically interacted with TBK1,and can reduce K63-linked polyubiquitination of TBK1.Knockdown of USP24 upregulated TBK1 K63-linked polyubiquitination,promoted the phosphorylation and nuclear translocation of IRF3,and in turn improved IFN-I production during EV71 infection.As a consequence,USP24 knockdown dramatically inhibited EV71 infection.This study revealed USP24 as a novel regulator of TBK1 activation,which promotes the understanding of immune evasion mechanisms of EV71 and could provide a potential strategy for treatment of EV71 infection.Lichao Zang Jin Gu Xinyu Yang Yukang Yuan Hui Guo Wei Zhou Jinhong Ma Yan Chen Yumin Wu Hui Zheng Weifeng Shi 2023Virologica Sinica2023,38,1:2
