先秦时期孔子和孟子分别从政治、家庭维度对《小弁》展开论说,毛诗学派的解读利用太子宜臼(咎)被周幽王废逐一事,综合了政治和家庭、君臣和父子之间的关系,得到了北宋至清代学者的普遍认可。《小弁》中超越家庭关系的政治性话语意蕴贯穿始终,传统的宜臼被父放逐说和闻一多的弃妇说等均忽略了这一现象。《毛诗序》将其视为刺诗自有道理,但其附诗于史的倾向使后世产生诸多争端。《小弁》抒发了君臣关系破裂后的贤人失志之悲,其内容当与父子无关,亦与宜臼无关。

为探究水路布置对冷却效率的影响,并建立水路数量与冷却时间之间的经验公式。研究基于传统加工条件下的水路冷却系统设计,以尺寸为200 mm×100 mm×2.24 mm的聚丙烯(PP)薄板注塑件为研究对象,利用NX UG10.0对PP薄板注塑件进行三维建模,使用Moldex 3D分析软件对选取不同的水路数量及间距组合进行有限元分析。将基于冷却系统设计经验公式计算出来的冷却时间与Moldex 3D分析软件模拟得到的冷却时间进行比较后,推导出水路数量与冷却时间之间的经验公式。该公式以水路数量、水路间距等作为自变量,以冷却时间作为因变量。试验结果表明:在只考虑水路数量、水路间距的前提下,在水路数量为30根,间距为22 mm时,最符合预期要求。同时发现,有效传热面积的变化对冷却效率影响显著,而水路间距的变化对冷却效率影响不明显。

氧气是机体进行新陈代谢和维持生存的必要因素。低氧适应是机体为了适应缺氧这一生理或病理现象,降低缺氧带来的影响而发生的一系列局部性和系统性的改变。竞争性内源RNA(ceRNA)是指具有同种miRNA反应元件(MREs)的RNA分子,竞争性结合miRNA在转录后水平调控基因的表达,进而影响细胞的生物学功能。ceRNA是一种复杂的网络调节机制,在细胞增殖与凋亡、炎症反应、能量代谢、肌肉发育、脂肪沉积、脂质代谢等方面发挥作用。文章总结了长链非编码RNA(lncRNA)、环状RNA(circRNA)和假基因的生物学功能和特点,阐述经过验证的ceRNA参与动物低氧适应的生物学功能,为哺乳动物低氧适应性研究提供参考。

研究多层螺旋CT血流动力学成像技术(MSCTPI)、磁共振成像技术(MRI)在肝癌患者经肝动脉化疗栓塞(TACE)术后肿瘤活性评估中的应用。选取2017年1月—2022年12月收治的45例原发性肝癌患者,TACE术后3~5周后进行MSCTPI、MRI、DSA检查,以DSA诊断为金标准,比较MSCTPI、MRI对肿瘤活性病灶的诊断情况,TACE术后复发及残余病灶的诊断敏感度、准确度及特异度,TACE术后肿瘤包膜的检查情况。45例原发性肝癌患者TACE术后,DSA诊断共有59个病灶,其中活性病灶51个;残留或复发病灶48个,术后无残余或复发病灶11个。MSCTPI、MRI病灶检出率分别为91.53%、96.61%,差异无统计学意义(P>0.05)。MSCTPI活性病灶数检出率(50.98%)低于MRI活性病灶数检出率(82.35%,P<0.05)。以DSA诊断为金标准分别与MSCTPI、MRI绘制四格表,MSCTPI诊断肝癌复发及残余病灶的准确度为79.66%,敏感度为81.25%,特异度为72.72%;MRI诊断肝癌复发及残余病灶的准确度为89.83%,敏感度为91.67%,特异度为81.82%。对患者术后肿瘤包膜检出率MSCTPI为16.95%,MRI为42.37%,MRI对患者术后肿瘤包膜检出率高于MSCTPI,差异有统计学意义(P<0.05)。MRI在肝癌患者TACE术后对肿瘤活性病灶、复发及残余病灶、肿瘤包膜临床诊断优于MSCTPI,评估残留病灶效能更好,值得在临床上推广使用。

BACKGROUND： Pancreatic cancer is one of the most aggressive malignancies and chemotherapy is an effective strategy for advanced pancreatic cancer. Gemcitabine （GEM） is one of first-line agents. However, GEM-based combination therapy has shown promising efficacy in patients with advanced pancreatic cancer. This meta-analysis aimed to compare the efficacy and safety of GEM-based combination therapy versus GEM alone in the treatment of advanced pancreatic *** SOURCES： A comprehensive search of literature was performed using PubMed, EMBASE, Web of Science and Cochrane Central Register of Controlled Trials. A quantitative meta-analysis was performed based on the inclusion criteria from all eligible randomized controlled trials. The outcome indicators included overall survival （OS）, 6-month survival, 1-year survival, progression-free survival/time-to-progression （PFS/TTP）, and toxicities. RESULTS： A total of nine randomized controlled trials involving 1661 patients were included in this meta-analysis. There was significant improvement in the GEM-based combination therapy with regard to the OS （HR=0.85, 95% CI： 0.76-0.95, P=0.003）, PFS （HR=0.76, 95% CI： 0.65-0.90, P-0.002）, 6-month survival （RR=1.09, 95% CI： 1.01-1.17, P=0.03）, and the overall toxicity （RR=l.68, 95% CI： 1.52-1.86, P〈0.01）. However, there was no significant difference in the 1-year ***： GEM-based combination chemotherapy might improve the OS, 6-month survival, and PFS in advanced pancreatic cancer. However, combined therapy also added toxicity.

Inorganic/organic nanohybrids composed of arrayed TiO_2 nanotubes（Ti NTs）/porphyrin nanoparticles（NPs） have been fabricated via a wet chemical approach. The inorganic component, particularly the arrayed one-dimensional（1D） nanostructures, provides high charge-carrier mobility and rapid charge transport. The organic component exhibits extensive visible light absorption and good solution processability. Additionally, the geometric restraint by supramolecular assembly renders an improved photostability. A combination of these two components could thus allow for an efficient solar energy conversion. In this work, a colloid of porphyrin NPs prepared by a solvent exchange method is coated on anodic Ti NTs by means of a dip-coating treatment to form inorganic/organic hybrids. The hybrids exhibit an improvement on solar absorption and a significant enhancement on photocurrent generation at a small bias compared with individual component. Herein, the inorganic/organic nanohybrids are proved to be excellent photoanodes highly responsive to visible light and thus pave a way to discover new inorganic/organic assemblies for high-performance optoelectronic applications, as well as for device integration.

Rice-duck （RD） and rice-fish （RF） ecological systems are major complex planting and breeding models of rice paddy fields in southern China. Studying the methane （CH4） and nitrous oxide （N2O） emissions and their economic value from these two ecosystems can provide theoretical and practical basis for further development and utilization of these classical agricultural techniques. CH4 and N2O emissions from RD and RF ecological systems were measured in situ by using static chambers technique. Using global warming potentials （GWPs）, we assessed the greenhouse effect of CH4 and N2O and their economic value. Results showed that the peaks of CH4 emission fluxes from RD and RF appeared at full tillering stage and at heading stage, and the average emission fluxes were significantly （P〈 0.05） lower than that from CK. N2O fluxes remained low when the field is flooded and high after draining the water. Compared with CK, the total amount of N2O emissions was significantly （P〈0.05） higher and slightly lower than those from RD and RF, respectively. In 2006 and 2007, the total greenhouse effect of CH4 and N20 from RD and RF were 4 728.3 and 4 611 kg CO2 ha^-1, 4 545 and 4 754.3 kg CO2 ha^-1, respectively. The costs of greenhouse effect were 970.89 and 946.81 RMB yuan ha^-1, and 933.25 and 976.23 RMB yuan ha^-1, respectively, which were significant lower than those from CK （5 997.6 and 5 391.5 RMB yuan ha^-1）. Except for the environment cost of CH4 and N2O, the economic benefits from RD and RF were 2 210.64 and 4 881.92 RMB yuan ha^-1; 3 798.37 and 5 310.64 RMB yuan ha^-1, respectively, higher than those from CK. Therefore, RD and RF complex ecological planting and breeding models can effectively decrease and control CH4 and N2O emissions, and they are two of the effective strategies to reduce greenhouse gases from rice paddy fields and contribute in alleviating global warming. Thus, their adoption is important to the environment together with their economy benefits.
