| 1 | Crystal structure of SARS-CoV-2 main protease in complex with protease inhibitor PF-07321332显示文摘Dear Editor,Since December 2019,the pandemic of coronavirus disease 2019(COVID-19)has taken a heavy toll on global health,creating an urgent need to develop effective strategies for prevention and treatment.The etiological agent,known as severe acute respiratory syndrome coronavirus 2(SARSCoV-2),has infected nearly 229.2 million people worldwide with more than 4.7 million deaths as of September 15,2021.Older age and preexisting health conditions are associated with worse clinical prognosis including higher mortality rates(Zhou et al.,2020).The global race to combat this pandemic has led to rapid deployment of numerous effective vaccines against SARS-CoV-2(Tregoning et al.,2021).However,the emergence of viral variants,including the Delta variant(B.1.617.2),compromised vaccine effectiveness with resurgence of SARS-CoV-2 infection among highly vaccinated population(Keehner et al.,2021).Therefore,development of therapeutics against the more conserved viral targets would be essential to contain the spread of COVID-19 and reduce mortality. | Yao Zhao Chao Fang Qi Zhang Ruxue Zhang Xiangbo Zhao Yinkai Duan Haofeng Wang Yan Zhu Lu Feng Jinyi Zhao Maolin Shao Xiuna Yang Leike Zhang Chao Peng Kailin Yang Dawei Ma Zihe Rao Haitao Yang | 2022 | Protein & Cell2022，13，9： | 6 |
| 2 | METTL5 stabilizes c-Myc by facilitating USP5 translation to reprogram glucose metabolism and promote hepatocellular carcinoma progression显示文摘Background:Hepatocellular carcinoma(HCC)is one of the most prevalent cancers in the world,with a high likelihood of metastasis and a dismal prognosis.The reprogramming of glucosemetabolism is critical in the development ofHCC.TheWarburg effect has recently been confirmed to occur in a variety of cancers,including HCC.However,little is known about the molecular biological mechanisms underlying the Warburg effect in HCC cells.In this study,we sought to better understand how methyltransferase 5,N6-adenosine(METTL5)controls the development of HCC and theWarburg effect.Methods:In the current study,quantitative real-time polymerase chain reaction and Western blotting were used to detect the expression of METTL5 in HCC tissues and cell lines.Several different cell models and animal models were established to determine the role of METTL5 in glucose metabolism reprogramming and the underlying molecularmechanism of HCC.Glutathione-S-transferase pulldown,coimmunoprecipitation,RNA sequencing,non-targeted metabolomics,polysome profiling,and luciferase reporter assays were performed to investigate the molecular mechanisms of METTL5 in HCC cells.Results:We discovered that METTL5 drove glucose metabolic reprogramming to promote the proliferation and metastasis of HCC.Mechanistically,upregulation of METTL5 promoted c-Myc stability and thus activated its downstream glycolytic genes lactate dehydrogenase A(LDHA),enolase 1(ENO1),triosephosphate isomerase 1(TPI1),solute carrier family 2 member 1(SLC2A1),and pyruvate kinase M2(PKM2).The c-Box and ubiquitin binding domain(UBA)regions of ubiquitin specific peptidase 5(USP5)binded to c-Myc protein and inhibited K48-linked polyubiquitination of c-Myc.Further study revealed that METTL5 controled the USP5 translation process,which in turn regulated the ubiquitination of c-Myc.Furthermore,we identified cAMP responsive element binding protein 1(CREB1)/P300 as a critical transcriptional regulator ofMETTL5 that promoted the transcription of METTL5 in HCC.In patient-derived tumor xenograft(PDX)models,adenovirus-mediated knockout of METTL5 had a good antitumor effect and prolonged the survival of PDX-bearing mice.Conclusions:These findings point to a novel mechanism by which CREB1/P300-METTL5-USP5-c-Myc controls abnormal glucose metabolism and promotes tumor growth,suggesting that METTL5 is a potential therapeutic target and prognostic biomarker for HCC. | Peng Xia Hao Zhang Haofeng Lu Kequan Xu Xiang Jiang Yuke Jiang Xiangdong Gongye Zhang Chen Jie Liu Xi Chen Weijie Ma Zhonglin Zhang Yufeng Yuan | 2023 | Cancer Communications2023，43，3： | 3 |
| 3 | Straight line feature based image distortion correction显示文摘An image distortion correction method is proposed, which uses the straight line features. Many parallel lines of different direction from different images were extracted, and then were used to optimize the distortion parameters by nonlinear least square. The thought of step by step was added when the optimization method working. 3D world coordination is not need to know, and the method is easy to implement. The experiment result shows its high accuracy. | Zhang Haofeng Zhao Chunxia Lu Jianfeng Tang Zhenmin Yang Jingyu | 2008 | Engineering Sciences2008，6，2： | 1 |

| 5 | Attitudes of hospitalized patients toward wearing patient clothing in Tianjin,China:A cross-sectional survey显示文摘Objective:To assess the attitudes of hospitalized patients toward wearing patient clothing and identify the factors those influence their negative attitudes.Methods:A cross-sectional design was employed and a questionnaire survey was conducted.The data were collected from 251 hospitalized patients between July 2015 and August 2015.Results:Around 57.8%of the participants reported that they were unwilling to wear patient clothing.Among them,60.7%knew little to nothing about the function of patient clothing.Some of these patients were unwilling to wear patient clothing because these uniforms had poor comfort(26.2%),fit(34.5%),hygiene(66.2%),and appearance(31.1%),and wearing them was psychologically uncomfortable(43.5%).Conclusions:More than half of the hospitalized patients dislike wearing patient clothing because they were unaware of its functions and were skeptical about its hygiene,comfortability,fit,and appearance.Therefore,these patients must be provided with comfortable,well fitting,hygienic,and aesthetically pleasing clothing. | Lu Liu Haofeng Zhao Gege Lu Yulu Ling Lingjie Jiang Huilan Cai Weijie Gao | 2016 | International Journal of Nursing Sciences2016，3，4： | 0 |
