| 2 | Spatial and temporal distribution of Neolithic sites in coastal China:Sea level changes, geomorphic evolution and human adaption显示文摘The East China coastal plain is one of the most important Neolithic culture areas in China, where rich archaeological sites including those producing the earliest domesticated rice are observed. It is also a place where landscape has experienced dramatic evolution during the Holocene when both sea level and climate changed, such that it is an ideal place for studying human-environment interaction. This study investigated over 2000 sites of pre-history and Shang and Zhou Dynasties, with 655 of which being Neolithic ages, by using DEM and GIS methods. The results suggest that the spatial and temporal distribution of Neolithic sites has largely been controlled by landscape evolution(particularly changes in coastal line), which ultimately governed by sea level changes. During early Holocene, Neolithic sites sparsely distributed in the intermountain basins of east Zhejiang Province, far from the influence of ocean. Over the period of 9–7 ka, the coastal plain(including the shelf) was largely submerged,only the feet of low hills to the south and southwest of the study area, and islands protruding the estuary, cradled limited number of settlements with characteristic 'maritime components'. At about 7 ka, sea level rise decelerated prominently, while sediments supply in the drainage remained high value, the combination of which led to land formation and propagation. Vast space during this period facilitated the growth of settlements in both size and number. In the mean time, however, the coastal plain was vulnerable to extreme environmental events such as storms and flooding owning to its geomorphic nature, which exerted great influence on the rise and fall of Neolithic culture. | ZHENG HongBo ZHOU YouSheng YANG Qing HU ZhuJun LING GuangJiu ZHANG JuZhong GU ChunGuang WANG YingYing CAO YeTing HUANG XianRong CHENG Yue ZHANG XiaoYu WU WenXiang | 2018 | Science China Earth Sciences2018,61,2: | 7 |
| 3 | Efficacy of rigosertib, a small molecular RAS signaling disrupter for the treatment of KRAS-mutant colorectal cancer显示文摘Objective:Mutant KRAS,the principal isoform of RAS,plays a pivotal role in the oncogenesis of colorectal cancer by constitutively activating the RAF/MEK/ERK and PI3K/AKT pathways.Effective targeted therapies are urgently needed.We investigated whether rigosertib,a benzyl styryl sulfone RAS signaling disruptor,could selectively kill KRAS-mutant colorectal cancer cells.Methods:CCK-8 was used to determine the cell viability.Patient-derived tumor and cancer cell xenograft models were used to detect the inhibitory efficacy of rigosertib.Flow cytometry was used to evaluate the apoptosis and cell cycle progression.Apoptosis and cell cycle arrest markers were detected by Western blot.DCFH-DA was used to determine the reactive oxygen species.Immunohistochemistry staining and Western blot were performed to characterize RAS signaling markers in colorectal cancer tissues and cells.Results:Rigosertib(RGS)exhibited a cytotoxic effect against colorectal cancer cells,which was greater in KRAS-mutant cells.Furthermore,RGS induced mitotic arrest and oxidative stress-dependent apoptosis in KRAS-mutant DLD1 and HCT116 cells.Besides,RGS disrupted RAS signaling,and the inhibition of RAS/MEK/ERK was independent of cellular oxidative stress.Using patient-derived xenograft models,the response and tumor inhibition of RGS were significantly higher in the KRAS-mutant subgroup,while p-MEK,p-ERK,and p-AKT levels of RGS-treated tumors were significantly decreased.Finally,in a KRAS-mutant,chemotherapy-resistant patient-derived xenograft model,RGS showed a stronger therapeutic effect than the combination standard therapy involving fluoropyrimidine+oxaliplatin/irinotecan+bevacizumab.Conclusions:These data showed that targeting RAS signaling using RGS could be a therapeutic treatment for KRAS-mutant colorectal cancer patients. | Xinyi Zhou Qian Xiao Dongliang Fu Haochen Zhang Yang Tang Jinjie He Yeting Hu Xiangxing Kong Fei Teng Xiangrui Liu Ying Yuan Kefeng Ding | 2022 | Cancer Biology & Medicine2022,19,2: | 2 |

| 5 | Proximity-enabled covalent binding of IL-2 to IL-2Rα selectively activates regulatory T cells and suppresses autoimmunity显示文摘Interleukin-2(IL-2)is a pleiotropic cytokine that orchestrates bidirectional immune responses via regulatory T cells(Tregs)and effector cells,leading to paradoxical consequences.Here,we report a strategy that exploited genetic code expansion-guided incorporation of the latent bioreactive artificial amino acid fluorosulfate-L-tyrosine(FSY)into IL-2 for proximity-enabled covalent binding to IL-2Rαto selectively promote Treg activation.We found that FSY-bearing IL-2 variants,such as L72-FSY,covalently bound to IL-2Rαvia sulfur-fluoride exchange when in proximity,resulting in persistent recycling of IL-2 and selectively promoting the expansion of Tregs but not effector cells.Further assessment of L72-FSY-expanded Tregs demonstrated that L72-FSY maintained Tregs in a central memory phenotype without driving terminal differentiation,as demonstrated by simultaneously attenuated expression of lymphocyte activation gene-3(LAG-3)and enhanced expression of programmed cell death protein-1(PD-1).Subcutaneous administration of L72-FSY in murine models of pristane-induced lupus and graft-versus-host disease(GvHD)resulted in enhanced and sustained therapeutic efficacy compared with wild-type IL-2 treatment.The efficacy of L72-FSY was further improved by N-terminal PEGylation,which increased its circulatory retention for preferential and sustained effects.This proximity-enabled covalent binding strategy may accelerate the development of pleiotropic cytokines as a new class of immunomodulatory therapies. | Bo Zhang Jiaqi Sun Yeshuang Yuan Dezhong Ji Yeting Sun Yudong Liu Shengjie Li Xingxing Zhu Xunyao Wu Jin Hu Qiu Xie Ling Wu Lulu Liu Boyang Cheng Yuanjie Zhang Lingjuan Jiang Lidan Zhao Fei Yu Wei Song Min Wang Yue Xu Shiliang Ma Yunyun Fei Lihe Zhang Demin Zhou Xuan Zhang | 2023 | Signal Transduction and Targeted Therapy2023,8,2: | 0 |
| 6 | Utilization of quantitative electroencephalogram in China:an online questionnaire survey显示文摘Background:Quantitative electroencephalogram(QEEG)is a tool that uses a computer to analyze brain activity monitored by electroencephalogram(EEG)according to measurements such as frequency,amplitude,and slope.The purpose of this study was to understand the current situation of QEEG utilization in China and further compare the situations among different regions and different levels of hospitals.Methods:An online questionnaire comprising 14 questions was designed.Statistical description and analysis were made for the results of the questionnaire survey.Results:A total of 158 people from 134 medical institutions participated in the survey.The participants came from 21 provinces,accounting for 61.76%(21/34)of the 34 provincial administrative regions in China.The Eastern China region accounted for 66.42%(89/134)of all the medical institutions that participated in this survey.Among the institutions surveyed,QEEG was routinely used in only 23.88%(32/134)of them.Among the medical institutions in which QEEG was routinely used,87.50%(28/32)of them were 3A-grade hospitals.Among the institutions with routine use of QEEG,56.25%(18/32)were affiliated hospitals of medical schools.There was a significant difference in the utilization of QEEG between the 3A-grade and non-3A-grade hospitals(P=0.040)and between the hospitals affiliated to medical schools and those non-affiliated to medical schools(P=0.020).Conclusions:The utilization of QEEG is still limited in China.There are differences in the use of QEEG among different hospitals and regions. | Jiayin Li Xiangyi Zhu Shengjie Pan Yeting Lu Xiaowei Hu | 2022 | Acta Epileptologica2022,5,3: | 0 |
