| 1 | Enhancement of acellular cartilage matrix scaffold by Wharton’s jelly mesenchymal stem cell-derived exosomes to promote osteochondral regeneration显示文摘Articular cartilage defect repair is a problem that has long plagued clinicians.Although mesenchymal stem cells(MSCs)have the potential to regenerate articular cartilage,they also have many limitations.Recent studies have found that MSC-derived exosomes(MSC-Exos)play an important role in tissue regeneration.The purpose of this study was to verify whether MSC-Exos can enhance the reparative effect of the acellular cartilage extracellular matrix(ACECM)scaffold and to explore the underlying mechanism.The results of in vitro experiments show that human umbilical cord Wharton’s jelly MSC-Exos(hWJMSC-Exos)can promote the migration and proliferation of bone marrow-derived MSCs(BMSCs)and the proliferation of chondrocytes.We also found that hWJMSC-Exos can promote the polarization of macrophages toward the M2 phenotype.The results of a rabbit knee osteochondral defect repair model confirmed that hWJMSC-Exos can enhance the effect of the ACECM scaffold and promote osteochondral regeneration.We demonstrated that hWJMSC-Exos can regulate the microenvironment of the articular cavity using a rat knee joint osteochondral defect model.This effect was mainly manifested in promoting the polarization of macrophages toward the M2 phenotype and inhibiting the inflammatory response,which may be a promoting factor for osteochondral regeneration.In addition,microRNA(miRNA)sequencing confirmed that hWJMSC-Exos contain many miRNAs that can promote the regeneration of hyaline cartilage.We further clarified the role of hWJMSC-Exos in osteochondral regeneration through target gene prediction and pathway enrichment analysis.In summary,this study confirms that hWJMSC-Exos can enhance the effect of the ACECM scaffold and promote osteochondral regeneration. | Shuangpeng Jiang Guangzhao Tian Zhen Yang Xiang Gao Fuxin Wang Juntan Li Zhuang Tian Bo Huang Fu Wei Xinyu Sang Liuqi Shao Jian Zhou Zhenyong Wang Shuyun Liu Xiang Sui Quanyi Guo Weimin Guo Xu Li | 2021 | Bioactive Materials2021，6，9： | 11 |

| 3 | Atmospheric Corrosion of Steel A3 Deposited with Ammonium Sulfate and in the Presence of Sulfur Dioxide显示文摘A laboratory study of the atmospheric corrosion of carbon steel deposited with (NH4)2SO4 in the presence of SO2 isreported. The different levels of (NH4)2SO4 (0, 15, 30, 45, 60μg.cm-2) were added on the surface of the samplesbefore the exposure. The corrosion was investigated by a combination of gravimetry, Fourier transform infraredspectroscope and scanning electron microscopy. A detailed knowledge about the corrosion products was acquired,both quantitatively and qualitatively. The results show that the metal loss increased and the increasing tendency ofcorrosion rates slowed down with the increasing exposure time. The phase constituents of the corrosion products aremainly c-FeO(OH), γ-FeO(OH), and δ-FeO(OH). | YeWAN ChuanweiYAN ChunanCAO JunTAN | 2003 | Journal of Materials Science & Technology2003，19，5： | 2 |

| 13 | Synthesis of Polymer-Supported Heteronuclear Rhodium- Cobalt Bimetallic Carbonyl Cluster Catalysts and Their Hydroformylation Properties显示文摘Tetranuclear Rh-Co bimetallic cluster was synthesized and characterized by IR and XPS. The properties of the anchored catalysts, its stability and the ligand effect were also studied. The experimental results show that the optimal conditions for the hydroformylation of hexene-1 are as follows: the temperature is 80℃, reaction time 8 h, pressure 5. 88×105 Pa, and molar ratio of H2/CO 1. 2/1. 0. Functional groups attached to the donor atom(N) possess more or less some influence on the catalytic behavior. Compared with the homogeneous cluster, the polymer-supported bimetallic cluster is more stable. After the catalytic reaction, the structure of the anchored catalysts was not destroyed. X-ray photoelectron spectroscopy characterization indicates that there is a weak interaction between the polymer support and the active metals. | He Binglin(Ho Ping-Lum), Sun Juntan, Li Hong, Sang Junjie and Zhao Fenzhi (Institute of Polymer Chemistry, Nankai University, Tianjin) | 1989 | Chemical Research in Chinese Universities1989，5，4： | 0 |
