We deeply regret that the representative image of invaded 143B cells treated with Z-GP-DAVLBH + AXL-KD in the lower panel of Fig. 6C was incorrect due to inadvertent mistake of copying and pasting in the process of assembling figures with Adobe Illustrator software. The image has now been corrected, and the quantification of cell invasion in Fig. 6C remains correct. The corrected version of Fig. 6C has been provided below, and the change did not affect the results and conclusions of this study. We have provided the original data of this figure to Editorial Office, and the Editorial Office or the corresponding authors can be contacted for original data access.

Engineering Sciences 2009年第3期7卷 88-92页

作者： Wang Changjiang Jiang Hanqiao chen minfeng Geng Zhanli Liu Pengfei School of Petrolemn and Natural Gas Engineering China University of Petroleum Beijing 102249 China Research Center of CNOOC Beijing 101049 China

Nine targets which stand both for the static characteristic of produced formations and the dynamic parameter of wells including the average permeability,variation coefficient of permeability,moving capability,remaining recoverable reserves,coefficient of flooding,daily oil production,increasing rate of water cut,cumulative liquid production per unit meter and efficiency index of oil production are selected as the evaluation indexes,a novel model to evaluate the porous formations in long-term waterflooding sand reservoir was established by using the support vector machine and clustering analysis. Data of 57 wells from Shentuo 21 block Shengli oilfield was analyzed by using the model. Four kinds of formation groups were gained. According to the analysis result,different adjustment solutions were put forward to develop the relevant formations. The Monthly oil production increased 7.6 % and the water cut decreased 8.9 % after the adjusted solutions. Good results indicate that the learning from this method gained will be valuable adding to other long-term waterflooding sand reservoirs in Shengli oilfield and other similar reservoirs worldwide.

Lymphatic metastasis is the main metastatic route for colorectal cancer, which increases the risk of cancer recurrence and distant metastasis. The properties of the lymph node metastatic colorectal cancer(LNM-CRC) cells are poorly understood, and effective therapies are still lacking. Here, we found that hypoxia-induced fibroblast activation protein alpha(FAPα) expression in LNM-CRC cells. Gain-or loss-function experiments demonstrated that FAPα enhanced tumor cell migration, invasion, epithelial-mesenchymal transition, stemness, and lymphangiogenesis via activation of the STAT3 pathway. In addition, FAPα in tumor cells induced extracellular matrix remodeling and established an immunosuppressive environment via recruiting regulatory T cells, to promote colorectal cancer lymph node metastasis(CRCLNM). Z-GP-DAVLBH, a FAPα-activated prodrug, inhibited CRCLNM by targeting FAPα-positive LNM-CRC cells. Our study highlights the role of FAPα in tumor cells in CRCLNM and provides a potential therapeutic target and promising strategy for CRCLNM.
