| 1 | Study of-amyloid adsorption and aggregation on graphite by STM and AFM显示文摘The scanning tunneling microscopy (STM) and the atomic force microscopy (AFM) have been applied to the direct study of the adsorption and aggregation of -amyloid(1-42)(A42) on the hydrophobic graphite surface. It was found that A42 were preferentially adsorbed on graphite defects such as the edges. A42 peptides self-assembled into intermediate protofibrils, which in turn self-associated to form fibrils. Usually, two or more fibrils intertwined to form the helical structure. These results will provide an important clue to studying the aggregation proc-ess of -amyloid. | WANG Zhigang, WAN Lijun, ZHOU Chunqing, FANG Xiaohong, WANG Chen & BAI Chunli Institute of Chemistry, Chinese Academy of Sciences, Beijing 100080, China Correspondence should be addressed to Bai Chunli (e-mail: clbai@ infoc3.icas.ac.cn) | 2003 | Chinese Science Bulletin2003，48，5： | 4 |
| 2 | Numerical and experimental investigations for an air cannon optimization显示文摘Air cannon is a kind of de-clogging device which produces impulse force by instantly releasing the compressed air deposited in a pressure vessel.Air cannons are widely used in the transport pipes of warehouses,docks,furnaces and coal mines.In this paper,the theoretical analysis with isentropic flow hypothesis is firstly conducted on a simplified model to deduce the theoretical maximum of impulse force.And numerical study is carried out to predict the steady and unsteady impulse forces via simulating the whole exhausting process of the air cannon.The results demonstrate that the impulse force can be improved via increasing the piston sleeve inlet length and increasing the nozzle diameter.Laval nozzle can also increase the impulse force of the air without increasing the air mass flow.The optimization of the air cannon is then conducted on the basis of the theoretical and numerical analyses.Experimental measurements indicate that the computations well simulate the working process of the air cannon and the impulse force of the optimized design is 50%higher than the original model.For the cases with working pressure of 0.8 MPa,the optimized design is 60%higher than the original one. | XU Jian CHEN HaiSheng TAN ChunQing CHEN HuanZhuo ZHOU GenSheng | 2011 | Science China(Technological Sciences)2011，54，2： | 3 |

| 5 | An invasive zone in human liver cancer identified by Stereo-seq promotes hepatocyte–tumor cell crosstalk,local immunosuppression and tumor progression显示文摘Dissecting and understanding the cancer ecosystem,especially that around the tumor margins,which have strong implications for tumor cell infiltration and invasion,are essential for exploring the mechanisms of tumor metastasis and developing effective new treatments.Using a novel tumor border scanning and digitization model enabled by nanoscale resolution-SpaTial Enhanced REsolution Omics-sequencing(Stereo-seq),we identified a 500µm-wide zone centered around the tumor border in patients with liver cancer,referred to as“the invasive zone”.We detected strong immunosuppression,metabolic reprogramming,and severely damaged hepatocytes in this zone.We also identified a subpopulation of damaged hepatocytes with increased expression of serum amyloid A1 and A2(referred to collectively as SAAs)located close to the border on the paratumor side.Overexpression of CXCL6 in adjacent malignant cells could induce activation of the JAK-STAT3 pathway in nearby hepatocytes,which subsequently caused SAAs’overexpression in these hepatocytes.Furthermore,overexpression and secretion of SAAs by hepatocytes in the invasive zone could lead to the recruitment of macrophages and M2 polarization,further promoting local immunosuppression,potentially resulting in tumor progression.Clinical association analysis in additional five independent cohorts of patients with primary and secondary liver cancer(n=423)showed that patients with overexpression of SAAs in the invasive zone had a worse prognosis.Further in vivo experiments using mouse liver tumor models in situ confirmed that the knockdown of genes encoding SAAs in hepatocytes decreased macrophage accumulation around the tumor border and delayed tumor growth.The identification and characterization of a novel invasive zone in human cancer patients not only add an important layer of understanding regarding the mechanisms of tumor invasion and metastasis,but may also pave the way for developing novel therapeutic strategies for advanced liver cancer and other solid tumors. | Liang Wu Jiayan Yan Yinqi Bai Feiyu Chen Xuanxuan Zou Jiangshan Xu Ao Huang Liangzhen Hou Yu Zhong Zehua Jing Qichao Yu Xiaorui Zhou Zhifeng Jiang Chunqing Wang Mengnan Cheng Yuan Ji Yingyong Hou Rongkui Luo Qinqin Li Liang Wu Jianwen Cheng Pengxiang Wang Dezhen Guo Waidong Huang Junjie Lei Shang Liu Yizhen Yan Yiling Chen Sha Liao Yuxiang Li Haixiang Sun Na Yao Xiangyu Zhang Shiyu Zhang Xi Chen Yang Yu Yao Li Fengming Liu Zheng Wang Shaolai Zhou Huanming Yang Shuang Yang Xun Xu Longqi Liu Qiang Gao Zhaoyou Tang Xiangdong Wang Jian Wang Jia Fan Shiping Liu Xinrong Yang Ao Chen Jian Zhou | 2023 | Cell Research2023，33，8： | 1 |

| 16 | Assemble four-arm DNA junctions into nanoweb显示文摘DNA is of structural polymorphism, which is useful in nanoarchitecture; especially, four-arm DNA junctions can be used to assemble nanowebs. The static four-arm DNA junctions were designed and synthesized. One-arm DNA and two-arm DNA came out simultaneously with the four-arm DNA junction’s formation. A new method, termed the two-step method, was proposed and the productivity of four-arm DNA junctions was increased. A nanoweb was assembled successfully, but it showed irregularity itself. It was not the same as we expected. We consider that it is a result from the flexibility of four-arm DNA junction. | ZHOU Chunqing TAN Zukun WANG Chen BAI Chunli CAO Enhua | 2001 | Chinese Science Bulletin2001，46，19： | 0 |
| 17 | Status of transjugular intrahepatic portosystemic shunt for portal hypertension in China:A national survey analysis显示文摘Aim:The transjugular intrahepatic portosystemic shunt(TIPS)procedure has been performed in China for 30 years,but our understanding of the status and difficulties associated with the use of TIPS for portal hypertension is incomplete.This study aims to investigate the current situation of the use of TIPS for portal hypertension,which should aid the development of TIPS in China.Methods:This study involved a questionnaire survey,initiated by the China Portal Hypertension Alliance(CHESS)to investigate the use of TIPS for portal hypertension in China.Questionnaires were released on the Internet between August 16,2022 and September 16,2022.Detailed information was collected from 545 hospitals contracted by the CHESS in China,which performed TIPS surgery in 2021.Results:The 545 hospitals covers the majority of hospitals in China that conduct TIPS intervention.In the survey,a total of 13,527 TIPS interventions were carried out with 94.1%(498/545)of them had a system of routine follow‐up after TIPS.The majority(42.6%[232/545])believed that the main indication of TIPS was the control of acute bleeding.Overall,48.1%(262/545)carried out early or pre‐emptive TIPS,53.0%(289/545)carried out TIPS for cavernous transformation of the portal vein,and 81.0%(441/545)chose routine embolization of collateral circulation during operation.Most used coils(97.0%[475/490])and biological glue(72.0%[353/490])as embolic materials,and 78.5%(428/545)routinely performed intraoperative portal pressure gradient measurements.When selecting TIPS stents,57.1%(311/545)chose viator‐specific stents,and 57.2%(312/545)chose conventional anticoagulation after TIPS.Conventional anticoagulation after TIPS is over a time interval of 3–6 months(55.4%[173/312]).The limitation of TIPS surgery is mainly its cost(72.3%[394/545])and insufficient understanding of the procedure by doctors in other related departments(77.4%[422/545]).Most of the hospital teams accept the use of domestic instruments in TIPS surgery(92.7%[505/545]).Conclusions:This survey shows that TIPS is an essential part of the treatment of portal hypertension in China.TIPS is widely used in Chinese patients with portal hypertension,and this survey presents a more comprehensive picture of the options and difficulties encountered in the implementation of TIPS.In the future,it is necessary to promote TIPS technology and further standardize surgical indications,routine operations,and instrument application. | Haibo Shao Xinwei Han Jianbo Zhao Junhui Sun Zhuting Fang Bin Xiong Xiaoli Zhu Weixin Ren Min Yuan Shiping Yu Meng Niu Weifu Lv Xueqiang Zhang Chunqing Zhang Lei Li Xuefeng Luo Yusheng Song Yilong Ma Tong Dang Hua Xiang Yun Jin Hui Xue Guiyun Jin Xiao Li Jiarui Li Shi Zhou Changlu Yu Song He Lei Yu Hongmei Zu Jun Ma Yanming Lei Ke Xu Xiaolong Qi | 2023 | Portal Hypertension & Cirrhosis2023，2，1： | 0 |
