The caudate lobe （Couinaud＇s segment 1） is located at the posterior part of the liver. Isolated resection of caudate lobe is a major challenge especially when it is carried out laparoscopically. We report a case of successful total laparoscopic resection of caudate lobe using the technique of curettage and aspiration on a hepatic hemangioma which measured 7 cm ×5 cm. As far as we know, this is the first report from Asia on isolated laparoscopic resection of the hepatic caudate lobe.

Zeolite nanosheets with a short b-axis thickness are highly desirable in lots of catalytic reactions due to their reduced diffusion resistance. Nevertheless, conventional synthesis methods usually require expensive structure-directing agents(SDAs), pricey raw materials, and eco-unfriendly fluorine-containing additives. Here, we contributed a cost-effective and fluoride-free synthesis method for synthesizing high-quality MFI zeolite nanosheets through a Silicalite-1(Sil-1) seed suspension and urea cooperative strategy, only with inexpensive colloidal silica as the Si source. Our approach was effective for synthesizing both Sil-1 and aluminum-containing ZSM-5 nanosheets. By optimizing key synthesis parameters,including seed aging time, seed quantity, and urea concentration, we achieved precise control over the crystal face aspect ratio and b-axis thickness. We also revealed a non-classical oriented nanosheet growth mechanism, where Sil-1 seeds induced the formation of quasi-ordered precursor particles, and the(010)crystal planes of these particles facilitated urea adsorption, thereby promoting c-axis-oriented *** obtained ZSM-5 nanosheets exhibited exceptional catalytic performance in the benzene alkylation with ethanol, maintaining stability for over 500 h, which is 5 times longer than traditional ZSM-5 catalysts. Furthermore, large-scale production of ZSM-5 nanosheets was successfully carried out in a 3 L highpressure autoclave, yielding samples consistent with those from laboratory-scale synthesis. This work marks a significant step forward in the sustainable and efficient production of MFI nanosheets using inexpensive and environmentally friendly raw materials, offering the broad applicability in catalysis.

资源型地区转型发展是当前我国区域发展中的热点问题之一。通过构建一个两部门、三区域的新新经济地理模型,设定了联系资源地-加工地的联合生产成本,以及联系加工地-消费地的商品贸易成本,重点研究这两个成本对资源型地区转型发展的影响。在理论模型中发现,降低联合生产成本,将抑制资源型地区转型升级;降低商品贸易成本,将推动资源型地区转型升级。同时,资源开采部门生产率下降将产生两方面的福利影响,一是直接导致本地工资下降,二是将导致产业结构升级,从而推动本地工资上升。使用现实数据进行了校验后发现,结构升级将给资源型地区带来正向收益,陕西取得的收益最大,山西次之,新疆最低;区域一体化对陕西的影响要大于山西,而新疆由于融入全国整体市场的相对滞后,对区域一体化基本不敏感。
