| 1 | 地肤子抑菌活性成分筛选显示文摘以最小抑菌浓度为指标,采用二倍稀释法分别测试地肤子乙醇提取物中的石油醚相、乙酸乙酯相、正丁醇相和水相萃取物对4株细菌和5株植物病原菌的抑制作用;再对抑菌活性较强的萃取物进行分离纯化,通过二倍稀释法测试所分离化合物的抑菌活性,并对其结构进行表征。结果表明,正丁醇相萃取物的抑菌活性最强,从中分离得到3个化合物,其中化合物Ⅰ的抑菌活性较强,对大肠杆菌具有显著的抑制作用,其最小抑菌浓度为31.3μg·mL-1,经1 HNMR、IR及高分辨质谱等鉴定化合物Ⅰ为齐墩果酸。齐墩果酸有较强的抑菌活性,是地肤子抑菌活性的物质基础。 | 闫梦茹 张文博 罗国平 Demetra Simion 王小宁 陈程 | 2019 | 化学与生物工程2019，36，2： | 15 |
| 2 | Endoscopic management and prevention of migrated esophageal stents显示文摘The use of self-expandable metallic stents has increased recently to palliate inoperable esophageal neoplasia and also in the management of benign strictures. Migration is one of the most common complications after stent placement and the endoscopist should be able to recognize and manage this situation. Several techniques for managing migrated stents have been described, as well as new techniques for preventing stent migration. Most stents have a 'lasso' at the upper flange which facilitates stent repositioning or removal. An overtube, endoloop and large polypectomy snare may be useful for the retrieval of stents migrated into the stomach. External fixation of the stent with Shim's technique is efficient in preventing stent migration. Suturing the stent to the esophageal wall, new stent designs with larger flanges and double-layered stents are promising techniques to prevent stent migration but they warrant validation in a larger cohort of patients. | Bruno da Costa Martins Felipe Alves Retes Bruno Frederico Medrado Marcelo Simas de Lima Caterina Maria Pia Simione Pennacchi Fabio Shiguehissa Kawaguti Adriana Vaz Safatle-Ribeiro Ricardo Sato Uemura Fauze Maluf-Filho | 2014 | World Journal of Gastrointestinal Endoscopy2014，6，2： | 3 |
