| 1 | 板块构造机制在显生宙初期发生转变显示文摘虽然目前对于板块构造何时成为主要构造机制存在争议,但是研究者普遍认为在古太古代已经完成转变。元古代时期,哥伦比亚超大陆向罗迪尼亚超大陆的转换,并未发生超大陆的完全裂解和聚合,而是岩石圈和环境的相对稳定期。相比之下,成冰期至今则发育有大量的被动大陆边缘,以及在425~225 Ma期间大幅增加的裂谷和大陆岛弧长度,表明存在与潘吉亚超大陆形成密切相关的激烈板块构造活动。 | 袁超(编译) Brown M Kirkland C L Johnson T E | 2020 | 矿物岩石地球化学通报2020，39，4： | 9 |

| 4 | Radial artery access site complications during cardiac procedures,clinical implications and potential solutions: The role of nitric oxide显示文摘Percutaneous coronary intervention for the treatment of coronary artery disease is most commonly performed in the UK through the radial artery,as this is considered to be safer than the femoral approach.However,despite improvements in technology and techniques,complications can occur.The most common complication,arterial spasm,can cause intense pain and,in some cases,procedural failure.The incidence of spasm is dependent on several variables,including operator experience,artery size,and equipment used.An antispasmolytic cocktail can be applied to reduce spasm,which usually includes an exogenous nitric oxide(NO)donor(glyceryl trinitrate).NO is an endogenous local vasodilator and therefore is a potential target for anti-spasm intervention.However,systemic administration can result in unwanted side-effects,such as hypotension.A method that adopts local delivery of NO might be advantageous.This review article describes the mechanisms involved in radial artery spasm,discusses the advantages and disadvantages of current strategies to reduce spasm,and highlight the potential of NO-loaded nanoporous materials for use in this setting. | Emma M Coghill Timothy Johnson Russell E Morris Ian L Megson Stephen J Leslie | 2020 | World Journal of Cardiology2020，12，1： | 4 |

| 6 | Hepatocytes isolated from neoplastic liver-immunomagnetic purging as a new source for transplantation显示文摘AIM: To investigate whether hepatocytes isolated from macroscopically normal liver during hepatic resection for neoplasia could provide a novel source of healthy hepatocytes, including the development of reliable protocols for malignant cells removal from the hepatocyte preparation. METHODS: Hepatocytes were procured from resected liver of 18 patients with liver tumors using optimised digestion and cell-enrichment protocols. Suspensions of various known quantities of the HT-29 tumor cell line and patient hepatocytes were treated or not with Ep-CAM-antibody-coated immunomagnetic beads in order to investigate the effi cacy of tumor-purging by immunomagnetic depletion, using a semi-quantitative RT-PCR method developed to detect tumor cells. Immunomagnetic bead-treated or bead-untreated tumor cell-hepatocyte suspensions were transplanted intra-peritoneally in Balb/C nude mice to assess the rates of tumor development. RESULTS: Mean viable hepatocyte yield was 9.3 x 106 cells per gram of digested liver with mean viability of 70.5%. Immunomagnetic depletion removed tumor cells to below the RT-PCR detection-threshold of 1 tumor cell in 106 hepatocytes, representing a maximum tumor purging efficacy of greater than 400 000-fold. Transplanted, immunomagnetic bead-purged tumor cell-hepatocyte suspensions did not form peritonealtumors in Balb/C nude mice. Co-transplantation of hepatocytes with tumor cells did not increase tumorigenesis of the tumor cells. CONCLUSION: Immunomagnetic depletion appears to be an effective method of purging contaminating tumor cells to below threshold for likely tumorigenesis. Along with improved techniques for isolation of large numbers of viable hepatocytes, normal liver resected for neoplasia has potential as another clinically useful source of hepatocytes | Aravin Gunasegaram Javed Akhter Peng Yao Loreena A Johnson Stephen M Riodan David L Morris | 2008 | World Journal of Gastroenterology2008，14，32： | 2 |
