| 1 | Total mesopancreas excision for pancreatic head cancer: analysis of 120 cases显示文摘Objective: To evaluate the feasibility and safety of total mesopancreas excision(TMpE) in the treatment of pancreatic head cancer. Methods: The clinical and pathological data of 120 patients with pancreatic head cancer who had undergone TMpE in our center from May 2010 to January 2014 were retrospectively analyzed. Results: The mean operative time was(275.0±50.2) min and the average intra-operative blood loss was(390.0±160.5) mL. Post-operative complications were reported in 45 patients, while no peri-operative death was noted. The specimen margins were measured in three dimensions, and 86 patients(71.6%) achieved R0 resection. Conclusions: TMpE is safe and feasible for pancreatic head cancer and is particularly helpful to increase the R0 resection rate. | Wenguang Wu Xu'an Wang Xiangsong Wu Maolan Li Hao Weng Yang Cao Ruifa Bao Sijun Su Jianhua Lu Wei Gong Weibin Shi Jun Gu Xuefeng Wang Yingbin Liu Zhiwei Quan Shuyou Peng | 2016 | Chinese Journal of Cancer Research2016，28，4： | 10 |
| 2 | Synergistic Catalysis of Enzymes and Biomimetic MOFs: Immobilizing Cyt c on Two-dimensional MOFs to Enhance the Performance of Peroxidase显示文摘Metal-organic frameworks(MOFs) have been widely regarded as promising carriers for enzyme immobilization owing to their advantages in improving loading and regulating interaction with enzymes. However, they are still suffering from the problems of slow mass transfer and compromising activity. In this paper, the active two-dimensional(2D) MOF of Cu-TCPP(Fe)[TCPP=tetrakis(4-carboxy-phenyl)porphyrin], which possesses the biomimetic architecture of peroxidase, was adopted to anchor cytochrome(Cyt c) for the enhancement of catalytic activity. The atomic/nanometer thickness and micrometer lateral dimension of 2D MOFs can ensure the full exposure of immobilized enzymes and a shorter diffusion distance for the reactant molecules. Besides, the active carrier can provide synergistic catalysis and activity compensation during the reaction. When tested in the decomposition reaction of H_(2)O_(2), Cyt c/Cu-TCPP(Fe) exhibited nearly twice catalytic activity and an accelerated catalytic rate compared to free Cyt c. | WANG Yitong MENG Fanchen SU Ruifa SUN Changrui HAN Qianqian ZHANG Weina ZHANG Suoying | 2022 | Chemical Research in Chinese Universities2022，38，6： | 0 |
| 3 | Incorporating metal nanoparticles in porous materials via selective heating effect using microwave显示文摘Metal nanoparticle@porous material composites have attracted increasing attention due to their excellent synergistic catalytic performance.However,it is a challenge to introduce metal nanoparticles into cavities of porous materials without agglomeration on the exterior.Despite the progress achieved,a universal approach that can integrate different kinds of metal nanoparticles and porous materials is still highly desirable.Here we report a facile and general approach to fabricating metal nanoparticle@porous materials by microwave-triggered selective heating.The microwave can pass through the non-polar solvent and act on the polar solvent in the porous materials,causing the polar solvent to be heated,vaporized,and away from the pores of porous materials.The local void produced by the escape of polar solvent facilitates non-polar solvent containing metallic precursor to be dragged into the narrow pores,followed by further reduction,resulting in the complete encapsulation of nanoparticles.A series of metal nanoparticles@porous materials,ranging from metal-organic frameworks(MOFs)to zeolites,are successfully prepared by this method and show excellent size selectivity in catalytic reactions. | Yingyu Zhou Jiacheng Liu Fuyuan Sun Junchen Ouyang Ruifa Su Fanchen Meng Yongqi Luo Cheng Xu Weina Zhang Suoying Zhang Fengwei Huo | 2024 | Nano Research2024，17，4： | 0 |
