| 1 | Current status of diagnosis and treatment of bladder cancer in China-Analyses of Chinese Bladder Cancer Consortium database显示文摘Objective:To investigate current status of diagnosis and treatment of bladder cancer in China.Methods:A database was generated by Chinese Bladder Cancer Consortium(CBCC).From January 2007 to December 2012,14,260 cases from 44 CBCC centers were included.Data of diagnosis,treatment and pathology were collected.Results:The average age was 63.5 year-old and most patients were male(84.3%).The most common histologic types were urothelial carcinoma(91.4%),adenocarcinoma(1.8%),and squamous carcinoma(1.9%).According to 1973 and 2004 WHO grading system,42.0%,41.0%,and 17.0% of patients were grade 1,2,and 3,and 16.0%,48.7%,and 35.3% of patients were papillary urothelial neoplasms of low malignant potential,low,and high grade,respectively.Non-muscle invasive bladder cancer(NMIBC)and muscle invasive bladder cancer(MIBC)were 25.2% and 74.1%,respectively(0.8% not clear).Carcinoma in situ was only 2.4%.Most patients were diagnosed by white-light cystoscopy with biopsy(74.3%).Fluorescence and narrow band imaging cystoscopy had additional detection rate of 1.0% and 4.0%,respectively.Diagnostic transurethral resection(TUR)provided detection rate of 16.9%.Most NMIBCs were treated with TUR(89.2%).After initial TUR,2.6%accepted second TUR,and 45.7%,69.9%,and 58.7% accepted immediate,induced,and maintenance chemotherapy instillation,respectively.Most MIBCs were treated with radical cystectomy(RC,59.7%).Laparoscopic RCs were 35.1%,while open RC 63.4%.Extended and standard pelvic lymph node dissection were 7% and 66%,respectively.Three most common urinary diversions were orthotopic neobladder(44%),ileal conduit(31%),and ureterocutaneostomy(23%).Only 2.3% of patients accepted neo-adjuvant chemotherapy and only 18%of T3 and T4 patients accepted adjuvant chemotherapy.Conclusion:Disease characteristics are similar to international reports,while differences of diagnosis and treatment exist.This study can provide evidences for revisions of the guideline on bladder cancer in China. | Kaiwen Li Tianxin Lin 无 Wei Xue Xin Mu Enci Xu Xu Yang Fubao Chen Guangyong Li Lulin Ma Guoliang Wang Chaozhao Liang Haoqiang Shi Ming Li Mao Tang Xueyi Xue Yisong Lv Yaoliang Deng Chengyang Li Zhiwen Chen Xiaozhou Zhou Fengshuo Jin Xudong Liu Jinxin Wei Lei Shi Xin Gou Weiyang He Liqun Zhou Lin Cai Baiye Jin Guanghou Fu Xiangbo Kong Hongyan Sun Ye Tian Lang Feng Tiejun Pan Yiyi Wu Dongwen Wang Hailong Hao Benkang Shi Yaofeng Zhu Qiang Wei Ping Han Changli Wu Dawei Tian Zhangqun Ye Zheng Liu Zhiping Wang Junqiang Tian Lin Qi Minfeng Chen Wei Li Jinchun Qi Gongxian Wang Longlong Fu Zhaolin Sun Guangheng Luo Zhoujun Shen Zhaowei Zhu Jinchun Xing Zhun Wu Dong Wei Xin Chen Yanqun Na Hongfeng Guo Chunxi Wang Zhihua Lu Chuize Kong Yang Liu Jin Yang Jianyun Hu Xin Gao Jielin Li Changjun Yin Pu Li Shan Chen Zhen Du Jiongming Li Yongji Yan Xu Zhang Shuang Huang Fangjian Zhou Zhiling Zhang Yinghao Sun Shuxiong Zeng Song Cen Jiaquan Zhou Hanzhong Li Jin Wen Jian Huang | 2015 | Asian Journal of Urology2015，2，2： | 21 |
| 2 | Selection and characterization of the novel anti-human PD-1 FV78 antibody from a targeted epitope mammalian cell-displayed antibody library显示文摘Currently,display-based methods are well established and widely used in antibody engineering for affinity maturation and structural stability improvement.We obtained a novel anti-human programmed death 1(PD-1)antibody using computer-aided design and a mammalian cell display technology platform.We used computer-aided modeling and distance geometry methods to predict and assign the key residues that contributed to the binding of human PD-L1 to PD-1.Then,we analyzed the sequence of nivolumab(an anti-human PD-1 antibody,referred to as MIL75 in the article)to determine the template for antibody design and library construction.We identified a series of potential substitutions on the obtained template and constructed a virtual epitope-targeted antibody library based on the physicochemical properties and each possible location of the assigned key residues.The virtual antibody libraries were displayed on the surface of mammalian cells as the antigen-binding fragments of full-length immunoglobulin G.Then,we used flow cytometry and sequencing approaches to sort and screen the candidates.Finally,we obtained a novel anti-human PD-1 antibody named FV78.FV78 competitively recognized the PD-1 epitopes that interacted with MIL75 and possessed an affinity comparable to MIL75.Our results implied that FV78 possessed equivalent bioactivity in vitro and in vivo compared with MIL75,which highlighted the probability and prospect of FV78 becoming a new potential antibody therapy. | Longlong Luo Shi Wang Xiaoling Lang Tingting Zhou Jing Geng Xinying Li Chunxia Qiao Jiannan Feng Beifen Shen Ming Lv Yan Li | 2018 | Cellular & Molecular Immunology2018，15，2： | 4 |
| 3 | Acrolein Aggravates Secondary Brain Injury After Intracerebral Hemorrhage Through Drp1-Mediated Mitochondrial Oxidative Damage in Mice显示文摘Clinical advances in the treatment of intracranial hemorrhage(ICH)are restricted by the incomplete understanding of the molecular mechanisms contributing to secondary brain injury.Acrolein is a highly active unsaturated aldehyde which has been implicated in many nervous system diseases.Our results indicated a significant increase in the level of acrolein after ICH in mouse brain.In primary neurons,acrolein induced an increase in mitochondrial fragmentation,loss of mitochondrial membrane potential,generation of reactive oxidative species,and release of mitochondrial cytochrome c.Mechanistically,acrolein facilitated the translocation of dynaminrelated protein 1(Drpl)from the cytoplasm onto the mitochondrial membrane and led to excessive mitochondrial fission.Further studies found that treatment with hydralazine(an acrolein scavenger)significantly reversed Drpl translocation and the morphological damage of mitochondria after ICH.In parallel,the neural apoptosis,brain edema,and neurological functional deficits induced by ICH were also remarkably alleviated.In conclusion,our results identify acrolein as an important contributor to the secondary brain injury following ICH.Meanwhile,we uncovered a novel mechanism by which Drpl-mediated mitochondrial oxidative damage is involved in acroleininduced brain injury. | Xun Wu Wenxing Cui Wei Guo Haixiao Liu Jianing Luo Lei Zhao Hao Guo Longlong Zheng Hao Bai Dayun Feng Yan Qu | 2020 | Neuroscience Bulletin2020，36，10： | 3 |
| 4 | Drp1-dependent remodeling of mitochondrial morphology triggered by EBV-LMP1 increases cisplatin resistance显示文摘Latent membrane protein 1(LMP1)is a major Epstein–Barr virus(EBV)-encoded oncoprotein involved in latency infection that regulates mitochondrial functions to facilitate cell survival.Recently,mitochondrial fission has been demonstrated as a crucial mechanism in oncovirus-mediated carcinogenesis.Mitochondrial dynamin-related protein 1(Drp1)-mediated mitochondrial fission has an impact on the chemoresistance of cancers.However,the mechanism by which oncogenic stress promotes mitochondrial fission,potentially contributing to tumorigenesis,is not entirely understood.The role of Drp1 in the oncogenesis and prognosis of EBV-LMP1-positive nasopharyngeal carcinoma(NPC)was determined in our study.We show that EBV-LMP1 exhibits a new function in remodeling mitochondrial morphology by activating Drp1.A high level of p-Drp1(Ser616)or a low level of p-Drp1(Ser637)correlates with poor overall survival and disease-free survival.Furthermore,the protein level of p-Drp1(Ser616)is related to the clinical stage(TNM stage)of NPC.Targeting Drp1 impairs mitochondrial function and induces cell death in LMP1-positive NPC cells.In addition,EBV-LMP1 regulates Drp1 through two oncogenic signaling axes,AMPK and cyclin B1/Cdk1,which promote cell survival and cisplatin resistance in NPC.Our findings provide novel insight into the role of EBV-LMP1-driven mitochondrial fission in regulating Drp1 phosphorylation at serine 616 and serine 637.Disruption of Drp1 could be a promising therapeutic strategy for LMP1-positive NPC. | Longlong Xie Feng Shi Yueshuo Li We Li Xinfang Yu Lin Zhao Min Zhou Jianmin Hu Xiangjian Luo Min Tang Jia Fan Jian Zhou Qiang Gao Weizhong Wu Xin Zhang Weihua Liao Ann MBode Ya Cao | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 1 |
| 5 | High-Affinity Decoy PD-1 Mutant Screened from an Epitope-Specific Cell Library显示文摘Immunotherapy with anti-programmed cell death protein-1(PD-1)/programmed cell death ligand-1(PDL1)monoclonal antibodies has become routine in the treatment of many kinds of human cancers,such as lung cancer,intestinal cancer,and melanoma.The PD-1/PD-L1 pathway inhibits T cell activation in the micro-environment,making it an attractive target against cancer.Wild-type(WT)PD-1 ectodomain has been shown to have difficulty blocking PD-1/PD-L1 mixture formation due to its low affinity.The present work uses three-dimensional(3D)crystal complex structures to analyze the interaction by which PD-1 binds to PD-L1 or PD-L2.It also reports on a theoretical study of the binding mode between PD-1 and its clinical antibody Opdivo.Based on the theoretical binding analysis of PD-1 and its ligands(i.e.,PD-L1 and PD-L2)or antibody(Opdivo),a small-content,epitope-oriented mammalian cell library was established for PD-1.After three rounds of cell sorting,the decoy PD-1 mutant 463,which presented a higher affinity than WT PD-1 to the PD-L1(the affinity has increased by almost three orders of magnitude)was screened out.It exhibited an inhibitory effect against PD-1 to prevent it from forming mixtures with PD-L1,which was similar to the effect of the commercial anti-PD-L1 antibody atezolizumab(ATE).The median effective concentration(EC50)value of the decoy mutant was 0.031 μg·mL^(-1) in comparison with 0.063 μg·mL^(-1) for ATE;both values were much lower than that of WT PD-1,at 2.571 μg·mL^(-1).The 463 decoy mutant reversed the inhibitory function of PD-1 in T cell activation;furthermore,10 mg·kg^(-1) of 463 inhibited about 75%of tumor growth in vivo in a MC38 transgenic xenograft mice model,which was similar to the activity of ATE.More interestingly,an even lower dose of 463(2 mg·kg^(-1))showed a better effect than 10 mg·kg^(-1) of WT PD-1.This work offers the decoy 463 with an improved curative effect,which holds potential to become a good option against PD-1/PD-L1-related cancers. | Hao Liu Chunxia Qiao Naijing Hu Zhihong Wang Jing Wang Jiannan Feng Beifen Shen Yuanfang Ma Longlong Luo | 2021 | Engineering2021，7，11： | 0 |

| 7 | Targeting the signaling in Epstein-Barr virus-associated diseases: mechanism, regulation, and clinical study显示文摘Epstein-Barr virus-associated diseases are important global health concerns.As a group I carcinogen,EBV accounts for 1.5%of human malignances,including both epithelial-and lymphatic-originated tumors.Moreover,EBV plays an etiological and pathogenic role in a number of non-neoplastic diseases,and is even involved in multiple autoimmune diseases(SADs).In this review,we summarize and discuss some recent exciting discoveries in EBV research area,which including DNA methylation alterations,metabolic reprogramming,the changes of mitochondria and ubiquitin-proteasome system(UPS),oxidative stress and EBV lytic reactivation,variations in non-coding RNA(ncRNA),radiochemotherapy and immunotherapy.Understanding and learning from this advancement will further confrm the far-reaching and future value of therapeutic strategies in EBV-associated diseases. | Ya Cao Longlong Xie Feng Shi Min Tang Yueshuo Li Jianmin Hu Lin Zha Luqing Zhao Xinfang Yu Xiangjian Luo Weihua Liao Ann MBode | 2021 | Signal Transduction and Targeted Therapy2021，6，2： | 0 |
| 8 | Study of the Compensatory Growth Following Starvation of Juvenile Golden Pompano Trachinotus ovatus显示文摘A starvation trial was conducted to determine compensatory growth of the juvenile golden pompano Trachinotus ovatus which were deprived of food for 1,2,5 and 7 days respectively. The results of tests in outdoor cement pools and net pens showed that,in the first 15 days and 30 days,the growth of 1 day and 2days-deprived groups was probably the same with that of control group,which accorded with fully compensatory description. However,the weight of 5 days and 7days-deprived fingerlings were lower than that of the control group,which accorded with the description of the partial compensatory growth. As the starvation prolonged,feed conversion efficiency of the starved groups increased and was higher than the control group. Meanwhile,feeding rate also increased,but the fish of 1day and 2 days-deprived groups was lower than that of the control group,and feeding quantity reduced and was lower than that of the control group. It suggested that the mechanism of compensatory growth was mainly due to improving feed conversion efficiency. Fish biochemical composition was analyzed: the water content and ash of fish sample increased due to starvation,while the lipid and protein decreased. The loss of lipid was greater than that of the protein,and the biochemical composition of fish in each group was restored to the control level by the end of the experiment. It suggested that Trachinotus ovatus may mainly consume lipid during the period of starvation. | Liu Longlong Luo Ming Chen Fuxiao Tan Wei Zhang Junbin Li Xiangmin | 2015 | Animal Husbandry and Feed Science2015，7，3： | 0 |
| 9 | Electric modulation of conduction in MAPbBr_(3) single crystals显示文摘The resistive switching(RS)mechanism of hybrid organic–inorganic perovskites has not been clearly understood until now.A switchable diode-like RS behavior in MAPbBr3 single crystals using Au(or Pt)symmetric electrodes is reported.Both the high resistance state(HRS)and low resistance state(LRS)are electrode-area dependent and light responsive.We propose an electric-fielddriven inner p–n junction accompanied by a trap-controlled space-charge-limited conduction(SCLC)conduction mechanism to explain this switchable diode-like RS behavior in MAPbBr_(3) single crystals. | Shanming Ke Shangyu Luo Jinhui Gong Liwen Qiu Renhong Liang Yangbo Zhou Bingcheng Luo Baochang Cheng Li Wang Longlong Shu | 2021 | Journal of Advanced Ceramics2021，10，2： | 0 |
