| 1 | Laparoscopic vs open partial colectomy in elderly patients:Insights from the American College of Surgeons- National Surgical Quality Improvement Program database显示文摘AIM: To compare the outcomes between the laparoscopic and open approaches for partial colectomy in elderly patients aged 65 years and over using the American College of Surgeons- National Surgical Quality Improvement Program(ACS NSQIP) database. METHODS: The ACS NSQIP database for the years 2005-2011 was queried for all patients 65 years and above who underwent partial colectomy. 1:1 propensity score matching using the nearest- neighbor method was performed to ensure both groups had similar preoperative comorbidities. Outcomes including postoperative complications, length of stay and mortality were compared between the laparoscopic and open groups. χ2 and Fisher's exact test were used for discrete variables and Student's t-test for continuous variables. P < 0.05 was considered significant and odds ratios with 95%CI were reported when applicable. RESULTS: The total number of patients in the ACS NSQIP database of the years 2005-2011 was 1777035. We identified 27604 elderly patients who underwent partial colectomy with complete data sets. 12009(43%) of the cases were done laparoscopically and15595(57%) were done with open. After propensity score matching, there were 11008 patients each in the laparoscopic(LC) and open colectomy(OC) cohorts. The laparoscopic approach had lower post-operative complications(LC 15.2%, OC 23.8%, P < 0.001), shorter length of stay(LC 6.61 d, OC 9.62 d, P < 0.001) and lower mortality(LC 1.6%, OC 2.9%, P < 0.001). CONCLUSION: Even after propensity score matching, elderly patients in the ACS NSQIP database having a laparoscopic partial colectomy had better outcomes than those having open colectomies. In the absence of specific contraindications, elderly patients requiring a partial colectomy should be offered the laparoscopic approach. | Umashankkar Kannan Vemuru Sunil K Reddy Amar N Mukerji Vellore S Parithivel Ajay K Shah Brian F Gilchrist Daniel T Farkas | 2015 | World Journal of Gastroenterology2015，21，45： | 3 |

| 15 | Strong and Superhydrophobic Wood with Aligned Cellulose Nanofibers as a Waterproof Structural Material显示文摘Lightweight structural materials are important for the energy efficiency of applications,particularly those in the building sector.Here,inspired by nature,we developed a strong,superhydrophobic,yet lightweight material by simple in situ growth of nano-SiO2 and subsequent densification of the wood substrate.In situ generation of SiO2 nanoparticles both inside the wood channels and on the wood surfaces gives the material superhydrophobicity,with static and dynamic contact angles of 159.4°and 3°,respectively.Densification of the wood to remove most of the spaces among the lumen and cell walls results in a laminated,dense structure,with aligned cellulose nanofibers,which in turn contributes to a high mechanical strength up to 384.2 MPa(7-times higher than natural wood).Such treatment enables the strong and superhydrophobic wood(SH-Wood)to be stable and have excellent water,acid,and alkaline resistance.The high mechanical strength of SH-Wood combined with its excellent structural stability in harsh environments,as well its low density,positions the strong and superhydrophobic wood as a promising candidate for strong,lightweight,and durable structural materials that could potentially replace steel. | Yongfeng Li Chaoji Chen Jianwei Song Chunpeng Yang Yudi Kuang Azhar Vellore Emily Hitz Mingwei Zhu Feng Jiang Yonggang Yao Amy Gong Ashlie Martini Liangbing Hu | 2020 | Chinese Journal of Chemistry2020，38，8： | 1 |
