Pancreatic cancer remains a lethal disease and is associated with poor prognosis, particularly for patients with distant metastasis at diagnosis. Recently, Oweira reported a retrospective study that included 13233 metastatic pancreatic cancer patients from the Surveillance, Epidemiology and End Results database. They demonstrated that pancreatic cancer patients with isolated liver metastases had worse outcomes than patients with isolated lung metastases or distant nodal metastases. At present, the standard treatment for metastatic pancreatic cancer is chemotherapy. However, improvement in the safety of pancreatic surgery has led to the consideration of more aggressive surgical approaches. Schneitler reported two cases of hepatic metastatic pancreatic cancer in which negative margin(R0) resection and long survival were achieved after effective preoperative chemotherapy. In general, these two studies indicate that although pancreatic cancer patients with liver metastasis have a poor prognosis, surgical approaches may prolong survival for a few of these patients. A strategy to select hepatic metastatic pancreatic cancer patients who may benefit from surgical intervention is urgently needed.

Background: LncRNA AK044604(regulator of insulin sensitivity and autophagy, Risa) and autophagy-related factors sirt1 and GSK3β play important roles in diabetic nephropathy(DN). In this study, we sought to explore the effect of Risa on sirt1/GSK3β-induced podocyte ***: Diabetic db/db mice received Risa-inhibition adeno-associated virus(AAV) via tail vein injection, and intraperitoneal injection of lithium chloride(LiCl). Blood, urine, and kidney tissue samples were collected and analyzed at different time points. Immortalized mouse podocyte cells(MPCs) were cultured and treated with Risa-inhibition lentivirus(LV), EX-527, and LiCl. MPCs were collected under different stimulations as noted. The effects of Risa on podocyte autophagy were examined by qRT-PCR, Western blotting analysis, transmission electron microscopy,Periodic Acid-Schiff staining, and immunofluorescence ***: Risa and activated GSK3β were overexpressed, but sirt1 was downregulated in DN mice and high glucosetreated MPCs(Psis. Risa overexpression attenuated sirt1-mediated downstream autophagy levels and aggravated podocyte injury by inhibiting the expression of sirt1(Psion enhanced sirt1-induced autophagy and attenuated podocyte injury, which could be abrogated by EX-527(Psion aggravated podocyte injury by decreasing ***: Risa could inhibit autophagy by regulating the sirt1/GSK3β axis, thereby aggravating podocyte injury in DN. Risa may serve as a therapeutic target for the treatment of DN.

土壤有机质(SOM)含量是表征土壤质量的关键指标,在全球碳循环系统中发挥重大作用。快速准确的SOM估算和空间制图对土壤碳库估算、作物生长监测和耕地规划管理具有重要意义。利用传统方法监测区域性SOM含量耗时费力,基于高光谱遥感影像建立SOM估测模型是现在较为合理有效的方法。为探索解决目前高光谱遥感影像建立SOM含量估测模型存在光谱数据冗余、光谱数据特征提取精度低、小样本模型泛化能力不强的问题,选择位于青海省湟中县的研究区,共采集67个土壤样本。获取资源1号02D(ZY1-02D)高光谱遥感影像并进行预处理得到样点像元光谱数据,采用分数阶微分变换(FOD)方法挖掘与SOM含量具有响应关系的敏感波段,以0.2为一个步长,利用相关性阈值法对比分析不同阶次微分处理数据挖掘能力;运用稳定性竞争性自适应重加权采样算法(sCARS)去除高光谱冗余数据获取建模特征波段,选择随机森林(RF)、极端梯度提升树、极限学习机和岭回归机器学习作为建模算法,以全波段和特征波段光谱数据分别作为模型输入变量构建SOM估测模型进行高光谱反演研究工作;最后根据最优特征变量和建模算法,基于ZY1-02D遥感影像进行了SOM空间分布制图。结果表明:采用FOD变换相比整数阶可以大大提高波段与SOM含量间的相关性,挖掘出更多细微的与SOM含量产生响应关系的光谱波段,其中0.8阶微分变换效果最优,较原始波段相比相关系数最大值提高了0.546;相较于全波段光谱数据,采用sCARS特征提取方法获取特征波段构建模型的估测精度得到较大提升,说明sCARS可以有效提升建模数据的质量,提升模型预测精度。建模算法中RF表现最优,R_(p)^(2)(模型决定系数)达到0.766,RPD达到1.86,较全波段建模结果R_(p)^(2)提升约7.58%;基于FOD-sCARS和RF实现了区域SOM含量估测制图。研究进一步验证利用星载高光谱遥感影像是实现区域SOM估测制图的可靠途径,研究结果可为估测区域SOM含量提供新思路,为利用星载高光谱遥感影像绘制SOM含量空间分布图提供了数据支持。

A combination of photochlorination ofp-xylene and succedent Friedel-Crafts alkylation polymerization was firstly used in the preparation of the hypercrosslinked adsorptive resin. The data of GC-MS and GC showed that a series of chlorizates were produced when p-xylene was photochlorinated. Hypercrosslinked resins could be synthesized by copolymerization, self-polymerization of chlorizates or post crosslinking reaction. The chemical structure and micromorphology of the porous resins were characterized by BET, FF-IR, SEM and elementary analysis （EA）. The results showed that the novel adsorptive resins possess high BET surface near to 1038 m^2/g and large pore volumes range from 0.5 to 1.2 cm^3/g.
