目的对比分析四点和两点悬吊固定术后患者人工晶状体的倾斜和偏心情况及其与视力预后的关系。方法选取2021年6月至2022年4月于保定市第一中心医院眼科因各种原因行人工晶状体悬吊固定术的患者80例80眼作为研究对象。将患者随机分为2组,试验组41例41眼,均行四点悬吊固定术;对照组39例39眼,均行传统的两点悬吊固定术。术后至少随访6个月,记录两组术眼术前及末次随访裸眼视力(UCVA)、最佳矫正视力(BCVA),应用全景超声生物显微镜(UBM)测量两组术眼术后人工晶状体倾斜角度及偏心距离。比较两组术眼术前及末次随访UCVA、BCVA,术后人工晶状体倾斜角度与偏心距离,采用Pearson相关分析对倾斜角度及偏心距离与术后UCVA、BCVA的相关性进行分析。结果试验组和对照组术眼末次随访时UCVA和BCVA均优于术前(均为P0.05)。对照组术眼人工晶状体水平倾斜度与术后UCVA和术后BCVA均呈正相关(均为P0.05),水平偏心距离与术后UCVA和术后BCVA均呈正相关(均为P0.05)。结论四点悬吊固定术与传统两点悬吊固定术均可有效提高患者术后视力,但四点悬吊固定术后术眼人工晶状体倾斜和偏心程度更小。

促进农村产业融合发展是推进乡村振兴、农业农村现代化的重要途径。数字经济在推动农村产业融合发展方面发挥着重要作用。文章基于2013-2022年中国30个省(区、市)面板数据,运用双向固定效应模型,从财政支农的视角考察了数字经济对农村产业融合发展的影响作用。结果表明,数字经济对我国农村产业融合发展具有显著的促进作用,且其影响效应具有区域异质性,对中部地区的影响效应显著高于其他地区,财政支农正向调节了数字经济对农村产业融合发展的促进作用。鉴于此,在推进数字经济与农村产业融合过程中,应该加强对农村地区数字基础设施建设、优化农村资源配置、优化农业数字风险管理、提高财政支农资金投入水平,因地制宜制定差异化战略。

以2010—2018年国有非金融上市公司为研究对象,分析了政府审计监管下,国有企业高管政企合作特征和晋升特征与企业影子银行业务的关系。研究结果表明:国有非金融企业高管政企合作特征与企业影子银行业务规模显著负相关,高管晋升特征与企业影子银行业务规模显著正相关;政府审计对上述关系起到不同程度的监管和威慑作用。进一步研究发现,企业显性金融资产受缚会使影子银行业务增加。这对于防止国有企业实体经济“脱实向虚”和研究政府审计影响国企高管决策的路径提供了理论支持。未来应进一步加强党组织对国有企业的领导;国家审计机关应对存在晋升预期的高管所在国企,增加审计力度和审计资源供给;同时,国有企业方面应当合理配置金融资产,降低金融资产错配率。

This paper aims to discuss an environmental, social, and economic analysis of energy utilization of crop residues from life cycle perspectives in China. The methodologies employed to achieve this objective are environmental life cycle assessment (E-LCA), life cycle cost (LCC), and social life cycle assessment (S-LCA). Five scenarios are developed based on the conversion technologies and final bioenergy products. The system boundaries include crop residue collection, transportation, pre-treatment, and conversion process. The replaced amounts of energy are also taken into account in the E-LCA analysis. The functional unit is defined as 1 MJ of energy produced. Eight impact categories are considered besides climate change in E-LCA. The investment capital cost and salary cost are collected and compared in the life cycle of the scenarios. Three stakeholders and several subcategories are considered in the S-LCA analysis defined by UNEP/SETAS guidelines. The results show that the energy utilization of crop residue has carbon emission factors of 0.09–0.18 kg (CO2 eq per 1 MJ), and presents a net carbon emissions reduction of 0.03–0.15 kg (CO2 eq per 1 MJ) compared with the convectional electricity or petrol, but the other impacts should be paid attention to in the biomass energy scenarios. The energy utilization of crop residues can bring economic benefit to local communities and the society, but the working conditions of local workers need to be improved in future biomass energy development.

A bacterial strain BAP5 with a relatively high degradation ability of benzo[a]pyrene （BaP） was isolated from marine sediments of Xiamen Western Sea, China and identified as Ochrobactrum sp. according to 16S rRNA gene sequence as well as Biolog microbial identification system. Strain BAP5 could grow in mineral salt medium with 50 mg/L of BaP and degrade about 20% BaP after 30 d of incubation. Ochrobactrum sp. BAP5 was able to utilize other polycyclic aromatic hydrocarbons （PAHs）（such as phenanthrene, pyrene and fluoranthene） as the sole carbon source and energy source, suggesting its potential application in PAHs bioremediation. The profile of total soluble protein from Ochrobactrum sp. BAP5 was also investigated. Some over- and special-expressed proteins of strain BAP5 when incubated with the presence of BaP were detected by two-dimensional polyacrylamide gel electrophoresis, and found to be related with PAHs metabolism, DNA translation, and energy production based on peptide fingerprint analysis through matrix-assisted laser desorption/ionization-time of flight mass spectrometry.

Although cholecystokinin octapeptide-8 is important for neurological function, its neuroprotective properties remain unclear. We speculated that cholecystokinin octapeptide-8 can protect human retinal pigment epithelial cells against oxidative injury. In this study, retinal pigment epithelial cells were treated with peroxynitrite to induce oxidative stress. Peroxynitrite triggered apoptosis in these cells, and increased the expression of Fas-associated death domain, Bax, caspase-8 and Bcl-2. These changes were suppressed by treatment with cholecystokinin octapeptide-8. These results suggest that cholecystokinin octapeptide-8 can protect human retinal pigment epithelial cells against apoptosis induced by peroxynitrite.
