1The mechanosensitive lncRNA Neat1 promotes osteoblast function through paraspeckle-dependent Smurf1 mRNA retention显示文摘Mechanical stimulation plays an important role in bone remodeling. Exercise-induced mechanical loading enhances bone strength,whereas mechanical unloading leads to bone loss. Increasing evidence has demonstrated that long noncoding RNAs(lnc RNAs) play key roles in diverse biological, physiological and pathological contexts. However, the roles of lnc RNAs in mechanotransduction and their relationships with bone formation remain unknown. In this study, we screened mechanosensing lnc RNAs in osteoblasts and identified Neat1, the most clearly decreased lnc RNA under simulated microgravity. Of note, not only Neat1 expression but also the specific paraspeckle structure formed by Neat1 was sensitive to different mechanical stimulations, which were closely associated with osteoblast function. Paraspeckles exhibited small punctate aggregates under simulated microgravity and elongated prolate or larger irregular structures under mechanical loading. Neat1 knockout mice displayed disrupted bone formation, impaired bone structure and strength, and reduced bone mass. Neat1 deficiency in osteoblasts reduced the response of osteoblasts to mechanical stimulation. In vivo, Neat1 knockout in mice weakened the bone phenotypes in response to mechanical loading and hindlimb unloading stimulation. Mechanistically, paraspeckles promoted nuclear retention of E3 ubiquitin ligase Smurf1 m RNA and downregulation of their translation, thus inhibiting ubiquitination-mediated degradation of the osteoblast master transcription factor Runx2, a Smurf1 target. Our study revealed that Neat1 plays an essential role in osteoblast function under mechanical stimulation, which provides a paradigm for the function of the lnc RNA-assembled structure in response to mechanical stimulation and offers a therapeutic strategy for long-term spaceflight-or bedrest-induced bone loss and age-related osteoporosis.Caizhi Liu Xingcheng Gao Yuheng Li Weijia Sun Youjia Xu Yingjun Tan Ruikai Du Guohui Zhong Dingsheng Zhao Zizhong Liu Xiaoyan Jin Yinlong Zhao Yinbo Wang Xinxin Yuan Junjie Pan Guodong Yuan Youyou Li Wenjuan Xing Guanghan Kan Yanqing Wang Qi Li Xuan Han Jianwei Li Shukuan Ling Yingxian Li 2022Bone Research2022,10,2:3
2Amelioration of imiquimod-induced psoriasis-like dermatitis in mice by DSW therapy inspired hydrogel显示文摘Psoriasis is a long-lasting and recurrent autoimmune disease which is incurable so far.Dead Sea water(DSW)therapy is an effective approach to help control the symptoms of psoriasis due to the abundant mineral ions in DSW,which inspired the material formulation in this study.Rubidium–Sodium alginate/Polyacrylamide hydrogels(Rb-SA/PAAm gels)composed of sodium alginate and polyacrylamide interpenetrating network structure with different concentrations of rubidium and certain magnesium and zinc content were prepared for the treatment of psoriasis.The obtained results suggest the good mechanical properties of the Rb-SA/PAAm gels including toughness and swelling performance.In terms of in vitro tests,the Rb-SA/PAAm gels not only show nontoxicity to human keratinocyte cell line(Hacats)but also inhibits the activity against inflammatory NF-κβ signaling pathway.Meanwhile,they can release Rb+which enable the Rb-SA/PAAm gels have better antibacterial ability to Streptococcus and Escherichia coli.The results obtained from in vivo tests indicate that these hydrogels could alleviate the symptoms of psoriasis caused by Imiquimod(IMQ)in mice by reducing the inflammatory factor in STAT3 pathway and therefore reduce the immune stimulation of the spleen.In conclusion,the 100Rb-SA/PAAm gel has demonstrated great potential to be a topical wettable dressing for psoriasis treatment.Xiang He Bing Zhu WeiJia Xie Yu He Jian Song Yi Zhang Chi Sun Hao Li QiYu Tang XinXin Sun Yanni Tan Yong Liu 2021Bioactive Materials2021,6,2:2

4A General Method for the Synthesis of Hybrid Nanostructures Using MoSe_(2) Nanosheet-Assembled Nanospheres as Templates显示文摘The layered transition metal dichalcogenides(TMDs)and transition metal phosphides are low-cost,earth-abundant,and robust electrocatalysts for hydrogen evolution reaction(HER).Integrating them into hybrid nanostructures is potentially promising to further boost the catalytic activity toward HER based on their synergistic effects.Herein,we report a general method for the synthesis of a series of MoSe_(2)-based hybrid nanostructures,including MoSe_(2)-Ni_(2)P,MoSe_(2)-Co_(2)P,MoSe_(2)-Ni,MoSe_(2)-Co,and MoSe_(2)-NiS,by postgrowth of Ni_(2)P,Co_(2)P,Ni,Co,and NiS nanostructures on the presynthesized MoSe_(2) nanosheet-assembled nanospheres,respectively,via a colloidal synthesis method.As a proof-of-concept application,the as-synthesized hybrid nanostructures are used as electrocatalysts for HER,exhibiting high activity and stability in acidic media.Among them,the MoSe_(2)-Co_(2)P composite shows the highest HER activity with an overpotential of 167 mV at 10 mA cm^(-2).Shikui Han Kai Zhou Yifu Yu Chaoliang Tan Junze Chen Ying Huang Qinglang Ma Ye Chen Hongfei Cheng Weijia Zhou Hua Zhang 2019Research2019,,1:1
5Embedding wasted hairs in Ti/PbO_(2) anode for efficient and sustainable electrochemical oxidation of organic wastewater显示文摘Despite of the hazardous risk of Pb^(2+) leakage, lead dioxide has been attributed as a quasi-ideal anode material with high oxygen evolution potential, excellent conductivity, good stability and low cost in electrochemical oxidation wastewater treatment technique. In this study, a novel Ti/PbO_(2) anode was fabricated by embedding raw materials that are readily and cheaply available, i.e., hairs. The structure-activity relationship of the new electrode was firstly revealed by material and electrochemical characterizations. Then different levels of pollutants (azo dye, phenol and maleic acid) were used to investigate the electrochemical oxidation performance of the new electrode. Finally, the accelerated electrode lifetime and Pb^(2+) leakage tests were carried out. Results showed that the embedded hairs changed the preferential crystallographic orientation of PbO_(2) and decreased the grain size. Hairs introduced additional roughness and active sites, and decreased the electrode impedance, especially under 5 mg/cm^(2) of embedding amount. The removal efficiencies of different target pollutants were enhanced more or less by embedding appropriate amount of hairs, depending on the current density, but loading excessive hairs had a negative effect. The accumulation of intermediate products during phenol degradation was also changed by the hairs. The new electrode could undergo ~550 h of harsh electrolysis. It is also relieved that the Pb^(2+) leakage was found to be suppressed during this long-term electrolysis process.Dan Shao Zekang Wang Cuiping Zhang Weijia Li Hao Xu Guoqiang Tan Wei Yan 2022Chinese Chemical Letters2022,33,3:1

7Pterostilbene antagonizes homocysteine-induced oxidative stress,apoptosis and lipid deposition in vascular endothelial cells显示文摘Hyperhomocysteinemia(HHcy)causes oxidative stress, induces apoptosis, and leads to damage to the vascular endothelium is the starting point of atherosclerosis. Pterostilbene(Pte)has been reported to have antioxidant and anti-apoptotic effects under various pathological conditions. The purpose of this study was to explore whether Pte can inhibit the oxidative stress and apoptosis of vascular endothelium induced by homocysteine(Hcy)and to explain the possible mechanism by which it occurs. The results showed that 20 μmol/L Pte significantly reduced the accumulation of reactive oxygen species, malondialdehyde, and lipids in cells induced by Hcy and promoted the activities of superoxide dismutase and catalase. The Hoechst 33342/PI staining assay showed that Pte antagonized Hcy-induced apoptosis. Pte inhibited Hcy-induced Akt dephosphorylation, increased p53, and decreased the Bcl-2/Bax ratio and caspase-9/caspase-3 activation in a dose-dependent manner. LY294002 pretreatment partially reversed the protective effect of Pte by blocking the PI3K/Akt pathway. Moreover, Pte reduced lipid deposition in human umbilical vein endothelial cells(HUVECs). This study proposes that Pte can inhibit Hcy-induced oxidative stress and apoptosis of HUVECs, and the PI3K/Akt/p53 signaling pathway of apoptosis was revealed. These results suggest that Pte exhibits significant potential for dealing with HHcy-induced vascular endothelial injury, such as atherosclerosis.Qiao Jiang Li Wang Xu Si Yuanyuan Bian Weijia Zhang Huijun Cui Hailong Gui Ye Zhang Bin Li Dehong Tan 2023Food Science and Human Wellness2023,12,5:1
8Retraction notice to“Amelioration of imiquimod-induced psoriasis-like dermatitis in mice by DSW therapy inspired hydrogel”[BIOMAT 6(2021)299-311]显示文摘This article has been retracted:please see Elsevier Policy on Article Withdrawal(http://gffzzf9eb861a10204708s09v0xbk9pouf6vcf.ffgz.tsg.suse.edu.cn/about/our-business/policies/article-withdrawal).This article has been retracted at the request of all the Authors,the Editor-in-Chief and the owner of the journal.The article has been retracted because of the authors recently re-conducted partly the experiments and found that the anti-bacteria behavior of Rb+was not reproducible.As shown in Fig.1(see enclosed file),at a centration as high as 200 mM,the addition of single Rb+does not show anti-bacteria effect.In Fig.2(see enclosed file),the authors prepared a mixed solution containing Rb+,Mg2+and Zn2+with concentrations close to those(12 h)in the article,and found that the mixed solution does not show anti-bacterial effect either.The two figures indicate that the anti-bacteria effect of Rb+is not conclusive,which seriously impairs the rigidity of the paper.Considering complex factors influencing the experiments with hydrogels,there might be other effects on the anti-bacteria behavior.However,since the anti-bacteria effect of Rb+is incorrect,the authors would like to retract the published article.Xiang He Bing Zhu WeiJia Xie Yu He Jian Song Yi Zhang Chi Sun Hao Li Qi Yu Tang XinXin Sun Yanni Tan Yong Liu 2022Bioactive Materials2022,7,1:0
9An adjustable anti-resonance frequency controller for a dual-stage actuation semi-active vibration isolation system显示文摘In the semiconductor manufacturing industry,the dynamic model of a controlled object is usually obtained from a frequency sweeping method before motion control.However,the existing isolators cannot properly isolate the disturbance of the inertial force on the platform base during frequency sweeping(the frequency is between 0 Hz and the natural frequency).In this paper,an adjustable anti-resonance frequency controller for a dual-stage actuation semi-active vibration isolation system(DSASAVIS)is proposed.This system has a significant anti-resonance characteristic;that is,the vibration amplitude can drop to nearly zero at a particular frequency,which is called the anti-resonance frequency.The proposed controller is designed to add an adjustable anti-resonance frequency to fully use this unique anti-resonance characteristic.Experimental results show that the closed-loop transmissibility is less than−15 dB from 0 Hz to the initial anti-resonance frequency.Furthermore,it is less than−30 dB around an added anti-resonance frequency which can be adjusted from 0 Hz to the initial anti-resonance frequency by changing the parameters of the proposed controller.With the proposed controller,the disturbance amplitude of the payload decays from 4 to 0.5 mm/s with a reduction of 87.5%for the impulse disturbance applied to the platform base.Simultaneously,the system can adjust the anti-resonance frequency point in real time by tracking the frequency sweeping disturbances,and a good vibration isolation performance is achieved.This indicates that the DSA-SAVIS and the proposed controller can be applied in the guarantee of an ultra-low vibration environment,especially at frequency sweeping in the semiconductor manufacturing industry.Bo ZHAO Weijia SHI Bingquan WANG Jiubin TAN 2021Frontiers of Information Technology & Electronic Engineering2021,22,10:0
10Assessing Empathy in Anesthesia Residents with the Chinese Version of the Consultation and Relational Empathy: A Pilot Standardized Patient Program显示文摘Objectives To validate the reliability of the Chinese version of the Consultation and Relational Empathy(CARE)in physician-standardized patient(SP)encounter.We also tried to examine the agreement between video-based ratings and in-room ratings,as well as the agreement between the faculty ratings and SP ratings.Methods The CARE was translated into Chinese.Forty-eight anesthesia residents were recruited to make preoperative interview in SP-counter.Performance of each resident was graded by in-room raters,video raters and SP raters.Consistency between different raters was examined.Results The Chinese-CARE measure demonstrated high scale reliability with a Cronbach's alpha value of 0.95 and high consistency in the in-room ratings in intraclass correlation(coefficient=0.888,P<0.001).Despite a good consistency in intraclass correlation,video ratings were significantly higher than in-room ratings(39.6±7.1 vs.24.0±10.0,P<0.001),and Wilcoxon signed-rank test indicated that the pass/fail rate was significantly higher based on video ratings than based on in-room ratings(45/48 vs.22/48,P<0.001).SP ratings had a moderate consistency with in-room faculty ratings(coefficient=0..568,P<0.001),and there was no significant difference between the pass/fail rates based on the in-room ratings and SP ratings(22/48vs.28/48,P=0.12).Conclusions The Chinese-CARE measure is reliable in the assessment of empathy during preoperative anesthesia interview.In-room and video ratings are not equivalent,while SP may provide a feasible alternative for the faculty rater in the assessment of communication skills with an appropriate measure.Yahong Gong Lijian Pei Xia Ruan Xu Li Xuerong Yu Ruiying Wang Weijia Wang Gang Tan Yuguang Huang 2021Chinese Medical Sciences Journal2021,36,2:0
