| 1 | Anatomical variation of infra-pyloric artery origination: A prospective multicenter observational study (IPA-Origin)显示文摘Objective: Infra-pyloric artery(IPA) is an important anatomical landmark in treatment of gastric cancer and is the key vessel for pylorus-preserving gastrectomy and subgroup of infra-pyloric lymph nodes. However, its anatomical variation is not thoroughly understood. Our study aimed to clarify the origination of the IPA.Methods: We did this prospective, multicenter, open-label, observational study at gastric surgery departments of34 hospitals in China. Gastric cancer patients aged 18 years or older and scheduled to undergo elective total or distal gastrectomy were assigned. During the surgery, IPA dissecting and exposing the origination point with photographs or video clips were required. The primary outcome was the origination of the IPA. Analysis of variance, χ~2 tests and Fisher's tests were used to analyze the differences between groups. The study is registered at Clinicaltrials.gov(No. NCT03071237).Results: Between May 8 and July 31, 2017, 429 patients were assigned for the study, and 419(97.7%) patients had the IPA dissected and recorded through photograph or video and were included in the primary outcome analysis. The median age was 62 years old, and 73.7% were male. Among the patients, 78.5% received laparoscopic surgery. Single IPA origination was identified in 398(95.0%) patients, including gastroduodenal artery(GDA) in154(36.8%) patients, anterior superior pancreaticoduodenal artery(ASPDA) in 130(31.0%) patients, and right gastroepiploic artery(RGEA) in 114(27.2%) patients. Fifteen(3.6%) patients were identified with multiple IPA and 6(1.4%) patients were identified as IPA absence. The differences in the distribution of surgical approach(P=0.003) and geographic area(P=0.030) were statistically significant. No difference was shown in sex, age,gastrectomy type, tumor location, and clinical T, N and M stage.Conclusions: Our study found that the IPA originates from GDA, ASPDA and RGEA in similar proportions.Laparoscopic surgery may be more helpful in dissection of the IPA than open surgery. | Rulin Miao Jianjun Qu Zhengrong Li Daguang Wang Jiang Yu Weidong Zang Yong Li Fenglin Liu Jian Zhang Wu Song Kai Ye Su Yan Wei Wang Shuangyi Ren Lu Zang Changqing Jing Li Zhang Kuan Wang Weihua Fu Lin Fan Bin Liang Gang Zhao Jun Cai Li Yang Jiaming Zhu Jun You Kun Yang Qingxing Huang Zhaojian Niu Ning Ning Xingfeng Qiu Gang Ji Feng Liang Hua Huang Chao Gao Fei Shan Shuangxi Li Yongning Jia Lianhai Zhang Xiangji Ying Yan Zhang Zhaode Bu Xiangqian Su Gang Zhao Ziyu Li Jiafu Ji | 2018 | Chinese Journal of Cancer Research2018，30，5： | 5 |
| 2 | Engineering CeO_(2)/CuO heterostructure anchored on upconversion nanoparticles with boosting ROS generation-primed apoptosisferroptosis for cancer dynamic therapy显示文摘Highly toxic reactive oxygen species(ROS)induced apoptosis and ferroptosis have been considered as significant cell death pathways for cancer therapy.However,insufficient amount of intracellular ROS extremely restricts the therapeutic effect.Toward this,we report a rationally designed nanocomposite(mUCC)with enhanced ROS generation ability,inducing the combination of apoptosis and ferroptosis through synergistic photodynamic therapy(PDT)and chemodynamic therapy(CDT).Under 808 nm near-infrared(NIR)light irradiation,photocatalytic reaction is triggered starting from the separation of electron-hole pairs on the surface of heterojunction(CeO_(2)/CuO),realizing improved ROS production.Simultaneously,mUCC served as Fenton-like agent exhibits considerable ability to generate highly toxic·OH under tumor microenvironment(TME).The boosted accumulation of ROS disrupts the redox balance within tumor cells and results in the integration of apoptosis and ferroptosis.In addition,mUCC shows satisfactory tumor targeting property benefiting from the cancer cell membrane functionalization under the guidance of magnetic resonance imaging(MRI)and NIR fluorescence imaging.The intelligent mUCC with good biocompatibility and excellent antitumor response achieves efficient tumor elimination under synergistic PDT and CDT.This work offers an elective approach for further development of ROS-based therapeutic nanoplatform in cancer therapy. | Xuan Gao Jing Feng Kehong Lv Yifei Zhou Ruohao Zhang Shuyan Song Hongjie Zhang Daguang Wang | 2023 | Nano Research2023，16，4： | 1 |
| 3 | Population genomic analysis reveals domestication of cultivated rye from weedy rye显示文摘Rye(Secale cereale)is an important crop with multiple uses and a valuable genetic resource for wheat breeding.However,due to its complex genome and outcrossing nature,the origin of cultivated rye remains elusive.The geneticist N.I.Vavilov proposed that cultivated rye had been domesticated from weedy rye,rather than directly from wild species like other crops.Unraveling the domestication history of rye will extend our understanding of crop evolution and upend our inherent understanding of agricultural weeds.To this end,in this study we generated the 8.5 Tb of whole-genome resequencing data from 116 worldwide accessions of wild,weedy,and cultivated rye,and demonstrated that cultivated rye was domesticated directly from weedy relatives with a similar but enhanced genomic selection by humans.We found that a repertoire of genes that experienced artificial selection is associated with important agronomic traits,including shattering,grain yield,and disease resistance.Furthermore,we identified a composite introgression in cultivated rye from the wild perennial Secale strictum and detected a 2-Mb introgressed fragment containing a candidate ammonium transporter gene with potential effect on the grain yield and plant growth of rye.Taken together,our findings unravel the domestication history of cultivated rye,suggest that interspecific introgression serves as one of the likely causes of obscure species taxonomy of the genus Secale,and provide an important resource for future rye and wheat breeding. | Yanqing Sun Enhui Shen Yiyu Hu Dongya Wu Yu Feng Sangting Lao Chenfeng Dong Tianyu Du Wei Hua Chu-Yu Ye Jinhuan Zhu Qian-Hao Zhu Daguang Cai Lidia Skuza Jie Qiu Longjiang Fan | 2022 | Molecular Plant2022，15，3： | 1 |
| 4 | Comprehensive characterization of donkey milk serum proteins显示文摘Donkey milk(DM)has attracted immense attention owing to its resemblance to human milk.Consequently,its components require rigorous analysis.This study aimed to identify DM serum proteins(DMSPs)using a label-free MS-based proteomics method.Herein,1243 DMSPs were characterized in Dezhou DM,and 788 common DMSPs were identified and subsequently analyzed.Gene ontology analysis indicated the involvement of these proteins in cellular components(extracellular exosomes,extracellular space,and focal adhesion),biological processes(small guanosine triphosphatase(GTPase)-mediated signal transduction,translation,and intracellular protein transport),and molecular functions(calcium ion binding,GTP binding,and poly(A)RNA binding).Additionally,metabolic pathway analysis confirmed that protein processing in endoplasmic reticulum is the most related metabolic pathway,followed by those of ribosomes,phagosomes,endocytosis,complement,and coagulation cascades.This study,aimed at decoding the DM composition,advances our understanding of the potential biological functions of DMSPs. | Mohan Li Qing Zhu Ruiyao Hong Daguang Feng Yiming Liu Xiqing Yue | 2022 | Journal of Future Foods2022，2，3： | 0 |
